tune2fs: Allow building it as a static lib
This allows getting all of tune2fs as a static library.
The entry point is
int tune2fs_main(int argc, char **argv).
It requires passing argv[0]="tune2fs" to get tune2fs behavior.

llseek: setup the correct seek for ext2fs_llseek
After
http://git.kernel.org/cgit/fs/ext2/e2fsprogs.git/commit/lib/ext2fs/llseek.c?id=274d46e1d35af423d0292d63c4d0ad7a03be82ba
with
__linux__
defined(HAVE_LSEEK64) && defined(HAVE_LSEEK64_PROTOTYPE)
SIZEOF_OFF_T >= SIZEOF_LONG_LONG
it leads to ext2fs_llseek() doing a "return lseek(fd, offset, origin);"
Which fails for offsets > 32bit.
Also, with
__linux__
!(defined(HAVE_LSEEK64) && defined(HAVE_LSEEK64_PROTOTYPE))
defined(HAVE_LLSEEK)
SIZEOF_OFF_T == SIZEOF_LONG_LONG
my_llseek is not defined at all. And there is no need to define
llseek as lseek, as llseek is never used.
Luckily ext2fs_llseek() then does "return lseek(...);"
It would seem that my_llseek should be used in both places.

Add files that would normally be generated by the e2fsprogs build system
Android doesn't run ./configure and friends, so it has to rely on
pre-populated versions of the autogenerated files.
This is somewhat bogus (e.g. hardcoded little-endian reference in
lib/ext2fs/ext2_types.h) and should at some point be fixed, but it's
what Android has always done, not a regression from the 1.41.14 branch.
Also, don't #include config.h which we don't generate (we pass what it
usually contains as -D parameters from Android.mk) anywhere.
Add a new Android.mk file for the quota library.

e2image: only skip writing zero blocks when writing to a new file
The e2image progam was originally intended to create image files.
However, some people have started using e2image to copy a file system
from one block device to another, since it is more efficient than
using dd because it only copies the blocks which are in use. If we
are doing this, however, we must not skip writing blocks which are all
zero in the source device, since they may not be zero in the
destination device.

Currently the ext4 block group descriptor is 64 bytes. In case we

debugfs, e2fsck: fix s_desc_size handling
The s_desc_size in the superblock specifies the group descriptor
size in bytes, but in various places the EXT4_FEATURE_INCOMPAT_64BIT
flag implies that the descriptor size is EXT2_MIN_DESC_SIZE_64BIT
(64 bytes) instead of checking the actual size. In other places,
the s_desc_size field is used without checking for INCOMPAT_64BIT.
In the case of ext2fs_group_desc() the s_desc_size was being ignored,
and assumed to be sizeof(struct ext4_group_desc), which would result
in garbage for any but the first group descriptor. Similarly, in
ext2fs_group_desc_csum() and print_csum() they assumed that the
maximum group descriptor size was sizeof(struct ext4_group_desc).
Fix these functions to use the actual superblock s_desc_size if
INCOMPAT_64BIT.
Conversely, in ext2fs_swap_group_desc2() s_desc_size was used
without checking for INCOMPAT_64BIT being set.
The e2fsprogs behaviour is different than that of the kernel,
which always checks INCOMPAT_64BIT, and only uses s_desc_size to
determine the offset of group descriptors and what range of bytes
to checksum.
Allow specifying the s_desc_size field at mke2fs time with the
"-E desc_size=NNN" option. Allow a power-of-two s_desc_size
value up to s_blocksize if INCOMPAT_64BIT is specified. This
is not expected to be used by regular users at this time, so it
is not currently documented in the mke2fs usage or man page.
Add m_desc_size_128, f_desc_size_128, and f_desc_bad test cases to
verify mke2fs and e2fsck handling of larger group descriptor sizes.

e2fsck: verify s_desc_size is power-of-two value
Add a LOG2_CHECK mode for check_super_value() so that it is easy
to verify values that are supposed to be power-of-two values
(s_desc_size and s_inode_size so far). In ext2fs_check_desc()
also check for a power-of-two s_desc_size.
Print out s_desc_size in debugfs "stats" and dumpe2fs output, if
it is non-zero.
It turns out that the s_desc_size validation in check_super_block()
is not currently used by e2fsck, because the group descriptors are
verified earlier by ext2fs_check_desc(), and even without an
explicit check of s_desc_size the group descriptors fail to align
correctly on disk. It makes sense to keep the check_super_block()
regardless, in case the code changes at some point in the future.

mke2fs: disallow creating FS on a loop mounted file with no option
When /etc/mtab is a symlink of /proc/mounts, mke2fs without -FF option
can create a filesystem on the image file that is mounted.
According to mke2fs man page, we should specify -FF option in this case.
This patch protects filesystem from unintended mke2fs caused by human error.
How to reproduce:
# mke2fs -t ext4 -Fq fs.img
# mount -o loop fs.img /mnt/mp1
# mke2fs -t ext4 -Fq fs.img && echo "mke2fs success"

libext2fs: only punch complete clusters
When bigalloc is enabled, using ext2fs_block_alloc_stats2() to free
any block in a cluster has the effect of freeing the entire cluster.
This is problematic if a caller instructs us to punch, say, blocks
12-15 of a 16-block cluster, because blocks 0-11 now point to a "free"
cluster.
The naive way to solve this problem is to see if any of the other
blocks in this logical cluster map to a physical cluster. If so, then
we know that the cluster is still in use and it mustn't be freed.
Otherwise, we are punching the last mapped block in this cluster, so
we can free the cluster.
The implementation given only does the rigorous checks for the partial
clusters at the beginning and end of the punching range.

build: use long long for __u64 by default
Don't print a verbose configure error in parse-types.h if

The printf formatting strings all use "%llu" for printing 64-bit

"unsigned long long" for __u64 in ext2-types.h and blkid-types.h

libext2fs: fail fileio write if we can't allocate a block
If we're using ext2fs_file_write() to write to a hole in a file,
ensure that we can actually allocate the block before updating i_size.
In other words, don't update i_size and don't return success if we hit
an error while allocating space.

libext2fs: don't overflow when punching indirect blocks with large blocks
On a FS with a rather large blockize (> 4K), the old block map
structure can construct a fat enough "tree" (or whatever we call that
lopsided thing) that (at least in theory) one could create mappings
for logical blocks higher than 32 bits. In practice this doesn't
happen, but the 'max' and 'iter' variables that the punch helpers use
will overflow because the BLOCK_SIZE_BITS shifts are too large to fit
a 32-bit variable. The current variable declarations also cause punch
to fail on TIND-mapped blocks even if the file is < 16T. So enlarge
the fields to fit.
Yes, this is an obscure corner case, but it seems a little silly if we
can't punch a file's block 300,000,000 on a 64k-block filesystem.

libext2fs: ind_punch() must not stop examining blocks prematurely
When we're iterating the main loop in ind_punch(), "offset" tracks how
far we've progressed into the block map, "start" tells us where to
start punching, and "count" tells us how many blocks we are to punch
after "start". Therefore, we would like to break out of the loop once
the "offset" that we're looking at has progressed past the end of the
punch range. Unfortunately, if start !=0, the if-break clause in the
loop causes us to break out of the loop early.
Therefore, change the breakout test to terminate the loop at the
correct time.

2/ 2 3/117 13348 - 13353 650276 - 650281 6
...
and we resize the fs in such a way that all of those blocks must
be moved down, we do them one at a time. Eventually we move 1-block
extent A) to a lower block, and then follow it with the other
blocks in the next logical offsets from extent C) in the next
interior node B).
The userspace extent code tries to merge, so when it finds that
logical 13228 can be merged with logical 13227 into a single extent,
it does. And so on, all through extent C), up to block 13250 (why
not 13251? [1]), and eventually move the node block as well.
So we end up with this when all the blocks are moved post-resize:
Level Entries Logical Physical Length Flags
...
2/ 2 120/122 13193 - 13193 33220 - 33220 1
2/ 2 121/122 13194 - 13194 33221 - 33221 1
2/ 2 122/122 13227 - 13250 33222 - 33245 24 D)
1/ 2 5/ 19 13228 - 17108 34676 3881 E) ***
2/ 2 1/222 13251 - 13251 33246 - 33246 1 F)
2/ 2 2/222 13275 - 13286 33247 - 33258 12
...
All those adjacent blocks got moved into extent D), which is nice -
but the next interior node E) was never updated to reflect its new
starting point - it says the leaf extents beneath it start at 13228,
when in fact they start at 13251.
So as we move blocks one by one out of original extent C) above, we
need to keep updating C)'s parent node B) for a proper starting point.
fix_parents() does this.
Once the tree is corrupted like this, more corruption can
ensue post-resize, because we traverse the tree by interior nodes,
relying on their start block to know where we are in the tree.
If it gets off, we'll end up inserting blocks into the wrong part
of the tree, etc.
I have a testcase using fsx to create a complex extent tree which
is then moved during resize; it hit this corruption quite easily,
and with this fix, it succeeds.
Note the first hunk in the commit is for going the other way,
moving the last block of an extent to the extent after it; this
needs the same sort of fix-up, although I haven't seen it in
practice.
[1] We leave the last block because a single-block extent is its
own case, and there is no merging code in that case. \o/

libext2fs: ext2fs_dup_handle should not alias MMP buffers
It turns out that resize2fs uses ext2fs_dup_handle to duplicate fs handles. If
MMP is enabled, this causes both handles to share MMP buffers, which is bad
news when it comes time to free both handles. Change the code to (we hope) fix
this. This prevents resize2fs from failing with a double-free error when
handed a MMP filesystem.

libext2fs, tests: allow /etc/mtab file to be missing
The environment variable EXT2FS_NO_MTAB_OK will suppress the error
code EXT2_NO_MTAB_FILE when the /etc/mtab file can not be found. This
allows the e2fsprogs regression test suite to be run in chroots which
might not have an /etc/mtab file.
By default will still want to complain if the /etc/mtab file is
missing, since we really don't want to discourage distributions and
purveyors of embedded systems from running without an /etc/mtab file.
But if it's missing it only results in a missing sanity check that
might cause file system corruption if the file system is mounted when
programs such as e2fsck, tune2fs, or resize2fs is running, so there is
no potential security problems that might result if this environment
variable is set inappropriately.

libext2fs: fix ext2fs_llseek on i386
ext2fs_llseek() was using lseek instead of lseek64. The
only time it would use lseek64 is if passed an offset that
overflowed 32 bits. This works for SEEK_SET, but not
SEEK_CUR, which can apply a small offset to move the file
pointer past the 32 bit limit.
The code has been changed to instead try lseek64 first, and
fall back to lseek if that fails. It also was doing a
runtime check of the size of off_t. This has been moved to
compile time.
This fixes a problem which would cause e2image when built for
x86-32 to bomb out when used with large file systems.

libext2fs: teach the ext2fs_*_block_bitmap_range2() about clusters
The ext2fs_{mark,unmark,test}_block_bitmap2() functions understand
about clusters, and will take block numbers and convert them to
clusters before checking the bitmap. The
ext2fs_*_block_bitmap_range2() functions did not do this, which made
them inconsistent. Fortunately, nothing has depended on this
incorrect behavior, and in fact most of the usage of these functions
have only recently been added, and only for optimizations that were
only enabled for non-bigalloc file systems.
So this is a change in previously exported functions, but (a) it
doesn't change the behavior at all for non-bigalloc file systems, and
(b) the change is more likely to fix bugs for bigalloc file systems.
For example, this change fixes a problem with resize2fs and bigalloc
file systems.

libext2fs: add the ext2fs_symlink() function
Creating symlinks is a complex affair when accounting for slowlinks.
Create a new function, ext2fs_symlink(), modeled after ext2fs_mkdir().
Like ext2fs_mkdir(), ext2fs_symlink() takes on the task of allocating a
new inode and block (for slowlinks), setting up sane default values in
the inode, copying the target path to either the inode (for fastlinks)
or to the first block (for slowlinks), and accounting for the inode and
block stats. Disallow link targets longer than blocksize as the Linux
kernel prevents this.
It does not attempt to expand the parent directory, instead returning
EXT2_ET_DIR_NO_SPACE and leaving it to the caller to expand just as
ext2fs_mkdir() does. Ideally, I think both of these functions should
make a single attempt to expand the directory.

libext2fs: remove m68k-specific bitops code
The current m68k code was buggy for multiple reasons; first the bfset,
et. al commands interpret the bit number as a signed number, not an
unsigned number. Secondly, there were missing memory clobbers. Since
there is no real benefit in using explicit asm's at this point (gcc is
smart enough to optimize the generic C code to use the set/clear/test
bit m68k instruction) fix this bug by removing the m68k specific asm
versions of these functions.
Tested on m68k-linux with e2fsprogs-1.42.6 and gcc-4.6.3 as before.
All tests pass and the debug output looks sane.
I compared the e2fsck binaries from the previous build with this
one. They had identical .text sizes, and almost the same number
of bit field instructions (obviously compiler-generated), so this
change should have no serious performance implications.

libext2fs: further optimize rb_test_bit
Profiling shows that rb_test_bit() is now calling ext2fs_rb_next() a
lot, and this function is now the hot spot when running e2freefrag.
If we cache the results of ext2fs_rb_next(), we can eliminate those
extra calls, which further speeds up both e2freefrag and e2fsck by
reducing the amount of CPU time spent in userspace.

libext2fs: remove pointless indirection in rbtree bitmaps
The code was previously allocating a single 4 or 8 byte pointer for
the rcursor and wcursor fields in the ext2fs_rb_private structure;
this added two extra memory allocations (which could fail), and extra
indirections, for no good reason. Removing the extra indirection also
makes the code more readable, so it's all upside and no downside.

mke2fs: recalculate the reserved blocks when the last BG is dropped
mke2fs -m option can set reserved blocks ratio up to 50%. But if the
last block group is not big enough to support the necessary data
structures, it gets dropped, we have to recalculate the number of
reserved blocks so that the reserved blocks matches the requested
percentage.
It also avoids a problem where if the user specifies a reserved blocks
of 50%, and after the last partial block group was dropped, if the
number of reserved blocks is greater than 50%, e2fsck will complain.
Steps to reproduce:
1. Create a FS which has the overhead for the last BG
and specify 50 % for reserved blocks ratio
# mke2fs -m 50 -t ext4 DEV 1025M
mke2fs 1.42.5 (29-Jul-2012)
warning: 256 blocks unused.
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
656640 inodes, 2621440 blocks
1310848 blocks (50.00%) reserved for the super user
~~~~~~~ <-- Reserved blocks exceed 50% of FS blocks count!
2. e2fsck outputs filesystem corruption
# e2fsck DEV
e2fsck 1.42.5 (29-Jul-2012)
Corruption found in superblock. (r_blocks_count = 1310848).
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:

Put ELF_OTHER_LIBS in the right place for the linker
Commit a7c17431b9 attempted to fix a problem where the system
libraries might get used instead of local libraries for things like
-lcom_err. It tried to accomplish this by moving $(ELF_OTHER_LIBS) to
before $(LDFLAGS).
Unfortunately, this was the wrong fix; $(ELF_OTHER_LIBS) *MUST* be
after the object files, or the linker might not pull in the necessary
library and not include it into the DT_NEEDED section of the shared
library. The proper fix is to add a -L$(LIB) before $(LDFLAGS), and
then remove the -L option from all of the ELF_OTHER_LIBS definitions
in the library Makefiles.

libext2fs: fix uninit block calculation when inodes_per_block < first_ino
The following commands:
dd if=/dev/zero of=/tmp/foo count=1 ibs=$(( 256 * 1024 * 1024 ))
mke2fs -N 256 -t ext4 /tmp/foo
... will cause mke2fs to write until it fills the device. The cause
for this is that the explicit request for 256 inodes causes the number
of inodes per block group to be 8. The ext2fs_initialize() function
assumed that all of the reserved inodes would be in the first block
group, which is not true in this case. This caused the number of
uninitialized inodes in the first block group to be negative, which
then resulted in mke2fs trying to zero out a very large number of
blocks. Oops.

Fix blhc (Build Log Hardening Check) warnings
The Build Log Hardening Check is a debian tool which scans the output
of a package build making sure that the security hardening flags are
used when compiling and linking all of binaries in a package.
For the most part we were passing CFLAGS, CPPFLAGS, and LDFLAGS down
to the compiler and link commands, but there there were one or two
exceptions. In addition, there where a few places in "make install"
where the V=1 option was not being honored, which triggered blhc
warnings since it couldn't analyze those commands.
The e2fsck.static was the only binary that was not getting built and
packaged with the hardening flags, but I've fixed all of the blhc
warnings so in the future it will be obvious if we regress.

libext2fs: fix block iterator for extents when truncating inodes
When e2fsck uses the block iterator to release the blocks in an
extent-mapped inode, when the last block in an extent is removed, the
current extent has been removed and the extent cursor is now pointing
at the next inode. But the block iterator code doesn't know that. So
when it tries to go the next extent, it will end up skipping an
extent, and so the inode will be incompletely truncated.
The fix is to go to the next extent before calling the callback
function for the current extent. This way, regardless of whether the
current extent gets removed, the extent cursor is still pointing at
the right place.

libext2fs: don't inline ext2fs_open_file() and ext2fs_stat()
The creation of inline wrappers ext2fs_open_file() and ext2fs_stat()
in commit c859cb1de0d624caa0779fb17d1a53766143136e in ext2fs.h caused
difficulties with the use of headers, since the headers for open64()
and stat64() may already be included (and skip the declaration of the
64-bit variants) before ext2fs.h is ever read. There is no real way
to solve the missing prototypes and resulting compiler warnings inside
ext2fs.h.
Since ext2fs_open_file() and ext2fs_stat() are not performance
critical operations, they do not need to be inline functions at all,
and the needed function headers can be handled properly in one file.
Similarly, posix_memalloc() was having difficulties with headers, and
was being defined in ext2fs.h, but it is now only being used by a
single file, so move the required header there.

libext2fs: fix rbtree backend for extent lengths greater than 2^32
For a completely full filesystem with more than 2^32 blocks, the
rbtree bitmap backend can assemble an extent of used blocks which is
longer than 2^32. If it does, it will overflow ->count, and corrupt
the rbtree for the bitmaps.
Discovered by completely filling a 32T filesystem using fallocate, and
then observing debugfs, dumpe2fs, and e2fsck all behaving badly.
(Note that filling with only 31 x 1T files did not show the problem,
because freespace was fragmented enough that there was no sufficiently
long range of used blocks.)

Change the include path in the Cflags field so that #include
<lib/foo.h> and <foo.h> will work. We had originally used a C flags
which allowed <foo.h> to work, but many applications (especially those
not using pkg-config) had been using the <lob/foo.h> formulation which
didn't require an explicit -I{$includedir} option to the C compiler.
If those applications then converted over to pkg-config, and the
e2fsprogs libraries were installed with a prefix other than /usr, so
that the header files were in some directory such as
/usr/local/include, a program that used #include <lib/foo.h> would
fail to compile.
So change the pkg-config files to include both -I{$includedir} and
-I{$includir}/lib.

Support systems without posix_memalign() and memalign()
MacOS 10.5 doesn't have posix_memalign() nor memalign(), but it does
have valloc(). The Android SDK would like to be built on MacOS 10.5,
so I've added support for a good-enough emulation of memalign()'s
functionality using valloc(), with an explicit test to make sure
valloc() is returning a pointer which is sufficiently aligned given
the requested alignment. This won't work if you try to operate on a
file system with a 16k blocksize using an e2fsprogs built on MacOS
10.5 system, but it is good enough for the common case of 4k
blocksize file systems, and we will let the memory allocation fail in
the alignment is not good enough.
I've also added a unit test for ext2fs_get_memalign() so we can be
sure it's working as expected. I've tested the code paths with
HAVE_POSIX_MEMALIGN defined, HAVE_POSIX_MEMALIGN undefined, and
HAVE_POSIX_MEMALIGN and HAVE_MEMALIGN undefined on an x86 Linux
system, and so I know the valloc() code path works OK. The simplistic
(and less safe) patch at:
https://trac.macports.org/attachment/ticket/33692/patch-lib-ext2fs-inline.c.diff
Shows that using valloc() apparently works OK for MacOS 10.5 (but if
it doesn't the unit test will catch a problem).

libext2fs: Implement ext2fs_find_first_zero_generic_bmap().
This function searches a bitmap for the first zero bit within a range.
It checks if there is a bitmap backend specific implementation
available (if the relevant field in bitmap_ops is non-NULL). If not,
it uses a generic and slow method by repeatedly calling test_bmap() in
a loop. Also change ext2fs_new_inode() to use this new function.
This change in itself does not result in a large speedup, rather it
refactors the code in preparation for the introduction of a faster
find_first_zero() for bitarray based bitmaps.

e2fsck: remove EXT4_EOFBLOCKS_FL flag handling
We've decided to remove EOFBLOCKS_FL from the ext4 file system entirely,
because it is not actually very useful and it is causing more problems
than it solves. We're going to remove it from e2fsprogs first and then
after the new e2fsprogs version is common enough we can remove the
kernel part as well.
This commit changes e2fsck to not check for EOFBLOCKS_FL. Instead we
simply search for initialized extents past the i_size as this should not
happen. Uninitialized extents can be past the i_size as we can do
fallocate with KEEP_SIZE flag.
Also remove the EXT4_EOFBLOCKS_FL from lib/ext2fs/ext2_fs.h since it is
no longer needed.

libext2fs: don't mark the superblock as dirty if the fs was opened r/o
If the file system is read/only opened with a backup superblock, and
the file system has uninit_bg enabled, the super block must not be
marked as dirty; otherwise, ext2fs_close() will call ext2fs_flush(),
which will fail, since the file descriptor for the block device was
opened read/only, and then the file descriptor won't actually be
closed.
This is normally not a problem since most of the time the program will
exit shortly after calling ext2fs_close(), and many programs don't
bother checking the error return from ext2fs_close(), especially if
the file system was opened read/only.
A big exception to this is e2fsck, since it opens and close the file
systems during its startup, and to make matters worse, registers an
error handler which will noisly complain about the failed writes
caused by ext2fs_flush().
Fix this by not marking the superblock as dirty if the file system was
opened read/only. The changes to the block group descriptors to clear
the uninit bits will still happen, so that e2fsck -n will properly
scan the whole file system. However, those changes will get dropped
when the file system handle is closed.

libext2fs, libe2p: Reserve RO_COMPAT_REPLICA feature
The replica is a feature which stores multiple copies of the key
metadata blocks so a single block failure in failure-prone media
(read: certain types of flash storage) doesn't take out the entire
file system.
Discussion on the upstream list proved not to be very positive on this
feature; the arguments were that it added complexity that wasn't
warrented, since common practice in industry is to insist on reliable
media, and if media is unreliable, you're kind of toast anyway (unless
the file system is being used as the back-end store of a cluster file
system where checksuming and data replication is happening above the
local disk file system level). So, this feature is being developed
out of tree.
We reserve the code points so that other people won't accidentally
step on them. Since it's not upstream, it's a soft reservation, but
it's not like we have any shortage of RO_COMPAT features. We are a
bit more tight on reserved inodes, but EXT2_BOOT_LOADER_INO and
EXT2_UNDEL_DIR_INO are not currently used anywhere, and
EXT2_EXCLUDE_INO is a reservation for another out-of-tree feature.
There are no features currently being discussed which require a
reserved inode, but if a need were to arise, we can claw back code
point reservations that were never used or not in tree, as those will
always be considered lower priority than in-tree features.

libext2fs: when truncating file, punch out blocks at end
Currently, ext2fs_file_set_size2 punches out data blocks between the
end of the file and infinity when truncate_block <= old_truncate
(i.e. when you've made the file longer). This is not a useful
behavior, particularly since it *fails* to punch out the data blocks
when the file is shortened (i.e. truncate_block < old_truncate). This
seems to be the result of the test being backwards, so fix the code to
punch only when the file is getting shorter.

libext2fs: add a bitmap implementation using rbtree's
For a long time we had a bitarray backend for storing filesystem
metadata bitmaps, however today this approach might hit its limits with
todays huge data storage devices, because of its memory utilization.
Bitarrays stores bitmaps as ..well, as bitmaps. But this is in most
cases highly unefficient because we need to allocate memory even for the
big parts of bitmaps we will never use, resulting in high memory
utilization especially for huge filesystem, when bitmaps might occupy
gigabytes of space.
This commit adds another backend to store bitmaps. It is based on
rbtrees and it stores just used extents of bitmaps. It means that it can
be more memory efficient in most cases.
I have done some limited benchmarking and it shows that rbtree backend
consumes approx 65% less memory that bitarray on 312GB filesystem aged
with Impression (default config). This number may grow significantly
with the filesystem size, but also it may be a lot lower (even negative)
if the inodes are very fragmented (need more benchmarking).
This commit itself does not enable the use of rbtree backend.
[ Simplified the code by avoiding unneeded memory allocation and
deallocation of del_ext. In addition, fixed a bug discovered by the
tst_bitmaps tests: rb_unamrk_bmap() must return true if the bit was
previously set in bitmap, and zero otherwise -- tytso ]

libext2fs: use HAVE_FSTAT64 instead of HAVE_STAT64 for ext2fs_stat()
Commit 6b56f3d92d introduced the use of HAVE_STAT64 without arranging
that it be defined in configure.in. Previously ext4.h used
HAVE_OPEN64, but apparently there are (broken) platforms that have
open64() but not stat64(). Go figure.
We do need to consistently use a single test for ext2fs_stat(),
ext2fs_fstat(), and struct ext2fs_struct_stat, or we could end up
passing a struct stat64 to a fstat() system call, or some such. I've
elected to use HAVE_FSTAT64 because: (a) it's already defined in the
configure script, and (b) if we ever come across a really broken
platform that defines fstat64() but not stat64(), we can always
emulate stat64() using open64() followed by a fstat64().
This commit fixed a bug whose symptoms were that mke2fs would not work
if given a file > 2GB on 32-bit platforms.

libext2fs: ext2fs_[set_]file_acl_block needs to check for 64-bit feature flag
The ext2fs_file_acl_block() and ext2fs_set_file_acl_block() needs to
only check i_file_acl_high if the 64-bit flag is set. This is needed
because otherwise we will run into problems on Hurd systems which
actually use that field for h_i_mode_high.
This involves an ABI change since we need to pass ext2_filsys to these
functions. Fortunately these functions were first included in the
1.42-WIP series, so it's OK for us to change them now. (This is why
we have 1.42-WIP releases. :-)

ext2fs: add multi-mount protection (INCOMPAT_MMP)
Multi-mount protection is feature that allows mke2fs, e2fsck, and
others to detect if the filesystem is mounted on a remote node (on
SAN disks) and avoid corrupting the filesystem. For e2fsprogs this
means that it checks the MMP block to see if the filesystem is in use,
and marks the filesystem busy while e2fsck is running on the system.
This is useful on SAN disks that are shared between high-availability
servers, or accessible by multiple nodes that aren't in HA pairs. MMP
isn't intended to serve as a primary HA exclusion mechanism, but as a
failsafe to protect against user, software, or hardware errors.
There is no requirement that e2fsck updates the MMP block at regular
intervals, but e2fsck does this occasionally to provide useful
information to the sysadmin in case of a detected conflict.
For the kernel (since Linux 3.0) MMP adds a "heartbeat" mechanism to
periodically write to disk (every few seconds by default) to notify
other nodes that the filesystem is still in use and unsafe to modify.

libext2fs: add flag to ext2fs_flush() and ext2fs_close() to avoid fsync
This adds new APIs: ext2fs_flush2 and ext2fs_close2 which take an
extra 'int flags' parameter.
This allows us to pass in an EXT2_FLAG_FLUSH_NO_SYNC flag which avoids
fsync'ing the filesystem when closing it. For the case we have in
mind where we are just constructing a throwaway ext2 filesystem in a
file in order to boot a VM, this saves over 5 seconds during the boot
process and avoids many unnecessary disk writes.
Existing code using ext2fs_flush and ext2fs_close remains unaffected

Shorten compile commands run by the build system
The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and
this was starting to cause some tools heartburn. It also made "make
V=1" almost useless, since trying to following the individual commands
run by make was lost in the noise of all of the defines.
So fix this by putting the configure-generated defines in lib/config.h
and the directory pathnames to lib/dirpaths.h.
In addition, clean up some vestigal defines in configure.in and in the
Makefiles to further shorten the cc command lines.

e2fsprogs: Fix some error cleanup path bugs
In inode_open(), if the allocation of &io fails, we go to cleanup
and dereference io to test io->name, which is a bug.
Similarly in undo_open() if allocation of &data fails, we
go to cleanup and dereference data to test data->real.
In the test_open() case we explicitly set retval to the only
possible error return from ext2fs_get_mem(), so remove that
for tidiness.
The other changes just make make earlier returns go through
the error goto for consistency.
In many cases we returned directly from the first error, but
"goto cleanup" etc for every subsequent error. In some
cases this leads to "impossible" tests such as:
if (ptr)
ext2fs_free_mem(&ptr)
on paths where ptr cannot be null because we would have
returned directly earlier, and Coverity flags this.
This isn't really indicative of an error in most cases, but
I think it can be clearer to always exit through the error goto
if it's used later in the function.

The user can either set the low or high part of the field via
"blocks_count_lo" or "blocks_count_hi", or both parts can be set via
"blocks_count".

libext2fs: add metadata checksum and snapshot feature flags
Reserve EXT4_FEATURE_RO_COMPAT_METADATA_CSUM and
EXT2_FEATURE_COMPAT_EXCLUDE_BITMAP. Also reserve fields in the
superblock and the inode for the checksums. In the block group
descriptor, reserve the exclude bitmap field for the snapshot feature,
and checksums for the inode and block allocation bitmaps.
With this commit, the metadata checksum and exclude bitmap features
should have reserved all of the fields they need in ext4's on-disk
format.
This commit also fixes an a missing byte swap for s_overhead_blocks.

e2fsprogs: Use punch hole as "discard" on regular files
If e2fsprogs tools (mke2fs, e2fsck) is run on regular file instead of
on block device, we can use punch hole instead of regular discard
command which would not work on regular file anyway. This gives us
several advantages. First of all when e2fsck is run with '-E discard'
parameter it will punch out all ununsed space from the image, hence
trimming down the file system image. And secondly, when creating an
file system on regular file (with '-E discard' which is default), we
can use punch hole to clear the file content, hence we can skip inode
table initialization, because reads from sparse area returns zeros. This
will result in faster file system creation (without the need to specify
lazy_itable_init) and smaller images.
This commit also fixes some tests that would fail due to mke2fs showing
discard progress, hence the output would differ.

The dump program relies on fs->frag_size and the

part of the kludgy way the dump program (which was originally written
for the BSD FFS was ported over to support ext2/3.) Given how it
makes assumptions about the ext2/3/4 file system being similar to the
BSD FFS, it's a bit of a miracle it works for ext4 --- or at least
appears to work...

Looking at gen_bitmap64.c:

A little more debugging showed that it was actually

Add the ability to skip zeroing journal blocks on disk. This can
significantly speed up mke2fs with large journals. At worst the
uninitialized journal is only a very short-term risk (if at all),
because the journal will be overwritten on any new filesystem as
soon as any significant amount of data is written to disk, and
the new journal TID would need to match the offset/TID of an old

ext2fs: Handle internal journal over 2^32 bytes
The write_journal_inode() code is only setting the low 32-bit i_size
for the journal size, even though it is possible to specify a journal
up to 10M blocks in size. Trying to create a journal larger than 2GB
will succeed, but an immediate e2fsck would fail. Store i_size_high
for the journal inode when creating it, and load it upon access.
Use s_jnl_blocks[15] to store the journal i_size_high backup. This
field is currently unused, as EXT2_N_BLOCKS is 15, so it is using
s_jnl_blocks[0..14], and i_size is in s_jnl_blocks[16].
Rename the "size" argument "num_blocks" for the journal creation functions
to clarify this parameter is in units of filesystem blocks and not bytes.

libext2fs: teach bitmap functions about bigalloc/cluster
This patch makes the following changes:
* ext2fs_allocate_block_bitmap() now allocates a bitmap with cluster
granularity for bigalloc file systems. For mke2fs and e2fsck, a
newly added function, ext2fs_allocate_subcluster_bitmap() allocates
a bitmap with block granularity (even for bigalloc file systems).
The newly added function ext2fs_get_bitmap_granularity() will return
the number of bits (log2) of the granularity used by the bitmap.
* The ext2fs_{mark,unmark,test}_block_bitmap2() functions will shift
their passed-in argument by log2(cluster_ganularity) bits right.
This means that the arguments for the single-argument bitmap
functions will be interpreted with block granluarity, since this
minimizes code changes in the rest of the code base.
* The ext2fs_{get,set}_block_bitmap_range() functions will interpret
their arguments in cluster granularity. This is a bit inconsistent,
but the caller of those functions will need to be taught about the
subtleties of clusters for bigalloc file systems.

e2image: Add support for qcow2 format
This commit adds support for exporting filesystem into QCOW2 image
format. Like sparse format this saves space, by writing only necessary
(metadata blocks) into image. Unlike sparse image, QCOW2 image is NOT
sparse, hence does not change its size by copying with not-sparse-aware
tools.
New options '-Q' has been added to tell the e2image to use QCOW2 as an
output image format. QCOW2 supports encryption and compression, however
e2image so far does no support such features, however you can still
scramble filenames with '-s' option.

mke2fs: make s_inodes_per_group >= 8 in ext2fs_initialize
current mkfs.ext4 fails if we tried with the following parameters:
mkfs.ext4 -m 0 -N 16 -O ^has_journal,^resize_inode,^uninit_bg,extent,meta_bg -b 1024 /dev/sdb3
It will cause segfault, but it is caused by another issue. See my
patch "mke2fs: Avoid segmentation fault in
ext2fs_alloc_generic_bmap". And with that patch, the mkfs.ext4 will
fail with the error: /dev/sdb3: Memory allocation failed while setting
up superblock
The reason is that in ext2fs_initialize, we align s_inodes_per_group
to 8, but fails to consider the case that s_inodes_per_group < 8.
So make at least 8 inodes for s_inodes_per_group.

add new superblock field: s_overhead_blocks
It turns out that it's very hard to calculate overheads in the face of
clustered allocation (bigalloc). This is because multiple metadata
blocks from different block groups can end up in the same allocation
cluster. Calculating the exact overhead requires O(all block bitmaps)
in memory, or O(number of block groups**2) in time. So we will
calculate this at mkfs time and stash it in the superblock.

e2fsprogs: enable user namespace xattrs by default
User namespace xattrs are generally useful, and I think extN
is the only filesystem requiring a special mount option to
enable them, when xattrs are otherwise available. So this
change sets that mount option into the defaults, via a
mke2fs.conf option.
Note that if xattrs are config'd off, this will lead to a
mostly-harmless:

e2fsprogs: turn off enforced fsck intervals by default
The forced fsck often comes at unexpected and inopportune moments,
and even enterprise customers are often caught by surprise when
this happens. Because a filesystem with an error condition will
be marked as requiring fsck anyway, I submit that the time-based
and mount-based checks are not particularly useful, and that
administrators can schedule fscks on their own time, or tune2fs
the enforced intervals if they so choose. This patch disables the
intervals by default, and I've added a new mkfs.conf option to
turn on the old behavior of random, unexpected, time-consuming
fscks at boot time. ;)

e2fsck: Discard free data and inode blocks.
In Pass 5 when we are checking block and inode bitmaps we have great
opportunity to discard free space and unused inodes on the device,
because bitmaps has just been verified as valid. This commit takes
advantage of this opportunity and discards both, all free space and
unused inodes.
I have added new set of options, 'nodiscard' and 'discard'. When the
underlying devices does not support discard, or discard ends with an
error, or when any kind of error occurs on the filesystem, no further
discard attempt will be made and the e2fsck will behave as it would
with nodiscard option provided.
As an addition, when there is any not-yet-zeroed inode table and
discard zeroes data, then inode table is marked as zeroed.

In order to provide generic "discard" function for all e2fsprogs tools
add a discard function prototype into struct_io_manager. Specific

This commit also creates unix_discard function which uses BLKDISCARD
ioctl to discard data blocks on the block device and bind it into
unit_io_manager structure to be available for all e2fsprogs tools.
Note that BLKDISCARD is still Linux specific ioctl, however other
unix systems may provide similar functionality. So far the
unix_discard() remains linux specific hence is embedded in #ifdef

Fix EXT4_FEATURE_RO_COMPAT_HUGE_FILE check
Creating a 4TB file on a filesystem with the 64bit flag set results in
e2fsck consistently complaining about i_blocks being wrong, with
confusing messages like this:
Inode 29818882, i_blocks is 8388608816, should be 8388608816. Fix? no
That appears to be caused by ext2fs_inode_i_blocks() checking for the
EXT4_FEATURE_RO_COMPAT_HUGE_FILE in the wrong place. Fix it.

libext2fs: make fs->group_desc opaque
To prevent direct array indexing of fs->group_desc[i] (because the
group_desc may be a different size for different filesystems) make it
an opaque pointer that may only be accessed through the accessor
functions in blknum.c. The type itself is still available in a public
header; if we have a group_desc that we know is one type or another,
it's ok to access its fields directly. This change only prevents us
from indexing off fs->group_desc[i] directly.
Old-style applications who don't want to change their source code can
(as a temporary short-term hack) #define EXT2FS_OLD_32_COMPAT before
including ext2fs.h.
Change the accessors in blknum.c to use ext4fs_group_desc(), a version
of ext2fs_group_desc() which returns a ext4_group_desc pointer.
This simplifies and collapses a fair bit of code in blknum.c

Reserve the EXT4_FEATURE_INCOMPAT_DIRDATA feature flag
Reserve the EXT4_FEATURE_INCOMPAT_DIRDATA feature flag for adding
extra file data in ext2_dir_entry_2 entries.
This changes the on-disk layout in the following way.
Firstly, the ext2_dir_entry_2 file_type field now has a mask: that
limits the "filetype" information to the low 4 bits of this field.
Since these values are sequentially assigned, this allows for up to 7
more filetypes to be assigned. When reading the "filetype" field, the
high 4 bits should be masked off when converting to DT_* filetypes for
userspace.
The high 4 bits of "filetype" are used as a bitmask to register up to
4 different "extended" directory entry fields. Extended data fields
are packed without alignment into the directory entry after the "name"
field in order of increasing bitmask value, for each field where bit
is set. In order to avoid the need to "understand" each of the
extended fields, the first byte of each extended data field holds the
size of that data field (including the size itself), so they can be
skipped if not understood. For fields that change the semantics of
the filesystem it is expected that a separate ROCOMPAT or INCOMPAT
field is registered.
There is a single dirent data type defined currently, for Lustre:
which holds a 128-bit file identifier. It is expected that if there
are 64-bit inode values that this will be assigned the 0x20 value.
Should a need ever arise to use all 4 of the extended dirent data
fields, it would be possible to keep the last bit (0x80) for use as a
multiplexor that stores a 1-byte aggregate data size, then a series of
"<u8_size><u8_type><data>" records in the last extended data record.
It is not expected that this will actually be needed in the lifetime
of ext4.

Reserve the EXT4_INCOMPAT_EA_INODE feature flag
Reserve the EXT4_INCOMPAT_EA_INODE feature flag for use with
large extended attributes that are stored in a separate inode.
This changes the on-disk format in several ways:
First, replace the e_value_block field with e_value_inum, so that
an xattr entry can reference an external inode. This field is
currently unused, as all of the entries live in the same block.
struct ext2_ext_attr_entry {
__u8 e_name_len; /* length of name */
__u8 e_name_index; /* attribute name index */
__le16 e_value_offs; /* offset in disk block of value */
> __le32 e_value_inum; /* inode in which the value is stored */
__le32 e_value_size; /* size of attribute value */
__le32 e_hash; /* hash value of name and value */
char e_name[0]; /* attribute name */
}
Second, add a flag to the inode that indicates it is using a large
(external) extended attribute. This is needed so that when unlinking
an inode the xattrs will be scanned to unlink the xattr inodes
referenced by the main inode.
Third, for inodes that have a number of xattrs that are larger than
a single block, but not large enough to justify an external inode
(less than 64kB total xattr size, due to e_value_offs limitation)
the ext2_ext_attr_header->h_blocks field can grow beyond a single
block to represent a contiguous allocation of blocks for the xattr.

mke2fs: account for physical as well as logical sector size
Some devices, notably 4k sector drives, may have a 512 logical
sector size, mapped onto a 4k physical sector size.
When mke2fs is ratcheting down the blocksize for small filesystems,
or when a blocksize is specified on the commandline, we should not
willingly go below the physical sector size of the device.
When a blocksize is specified, we -must- not go below
the logical sector size of the device.
Add a new library function, ext2fs_get_device_phys_sectsize()
to get the physical sector size if possible, and adjust the
logic in mke2fs to enforce the above rules.

namei.o is also needed by e2initrd_helper.
Long term, if we care about reduced e2fsprogs builds, we need a more
general solution for deciding what .o files are needed for a
particular build. Given that install floppies are going (gone?) the

libext2fs: Add some fail-safe checks to the 32-bit bitmap code
If a 64-bit bitmap is passed to a 32-bit bitmap function, add some
checks to make sure that we print a useful error message so we can
better catch potential problems.

libext2fs: Improve flex_bg inode table placement algorithm
When trying to find the best place for the inode table in the last
flex block group, use the true size for the flex_bg's portion of the
inode table instead of the worst case required size of the inode table
fragment if the file system is resized. This fixes a corner case
where if the size of the filesystem is just big enough that there is
only room for a single block group in the last flex_bg, and that
partial block group is too small for the full portion of the inode
table, the inode table is placed in the very first block group:
Group 64: (Blocks 2097152-2099199) [INODE_UNINIT, ITABLE_ZEROED]
Checksum 0xd305, unused inodes 8080
Block bitmap at 2097152 (+0), Inode bitmap at 2097168 (+16)
Inode table at 8626-9130 (+4292878770)
^^^^^^^^^

libext2fs: Fix SET_BMAP bugs in ext2fs_bmap() and ext2fs_bmap2()
Don't byte-swap the block number when setting i_block[x], since the
write_inode function will take of byte swapping the inode.
The phys_blk parameter contains an input parameter in the SET_BMAP
case, so it must be passed to ext2fs_bmap2() from the legacy function
ext2fs_bmap().

libext2fs: don't swap extent-based journal backup
The f_illitable_flexbg test was failing on ppc, because
e2fsck_move_ext3_journal is doing a direct memcmp of i_block with
s_jnl_blocks, and failing.
This is because we don't swap extent data on read from disk; rather
we do it when we access the extents. However, ext2fs_swap_super
was swapping s_jnl_blocks unconditionally, so these didn't match.
Looks like we need to treat s_jnl_blocks the same as i_block, and
swap it on access, not on read. Except for the last i_size bit...

libext2fs: clean up ext2fs_bg_flags_ interfaces
The ext2fs_bg_flag* functions were confusing.
Currently we have this:
void ext2fs_bg_flags_set(ext2_filsys fs, dgrp_t group, __u16 bg_flags);
void ext2fs_bg_flags_clear(ext2_filsys fs, dgrp_t group,__u16 bg_flags);
(_set (unused) sets exactly bg_flags; _clear clears all and ignores bg_flags)
and these, which can twiddle individual bits in bg_flags:
void ext2fs_bg_flag_set(ext2_filsys fs, dgrp_t group, __u16 bg_flag);
void ext2fs_bg_flag_clear(ext2_filsys fs, dgrp_t group, __u16 bg_flag);
A better interface, after the patch below, is just:
ext2fs_bg_flags_zap(fs, group) /* zeros bg_flags */
ext2fs_bg_flags_set(fs, group, flags) /* adds flags to bg_flags */
ext2fs_bg_flags_clear(fs, group, flags) /* clears flags in bg_flags */
and remove the original ext2fs_bg_flags_set / ext2fs_bg_flags_clear.

libext2fs: Round up the bitmap size when allocating a new bitmap
The x86 BT assembly instructure can overshoot the end of a bit array
when testing a bit at the end of the bit array, even if it never needs
to look at those memory locations. This can cause a spurious
segmentation fault. If we allocate a little extra memory, it avoids
this problem. See:
http://faydoc.tripod.com/cpu/bt.htm
This doesn't happen on Linux, probably because of the glibc's malloc()
function works, but apparently it's a major problem on the *BSD
operating systems.

libext2fs: Make ext2fs_extent_set_bmap() more robust against ENOSPC
In the case where we ext2fs_extent_set_bmap() is replacing the block
mapping at the beginning of an already-existing extent, insert a new
extent if necessary before shrinking an existing extent, to avoid data
loss if the disk is full.
This mostly addresses the problem described in Red Hat Bugzilla's
statistics are still wrong, but at least the files on the filesystem
are not corrupted. If there is a failure during the
inode_scan_and_fix pass, the simplest thing to do may be to tell the
user to run e2fsck -fy.

libext2fs: reset handle after inserting new extent
Commit 53422e moved the new extent insertion in
ext2fs_extent_set_bmap() prior to the modification of the original
extent, but the insert function left the handle pointing to the new
extent. This left us modifying the -new- extent, instead of the
original one, and winding up with a corrupt extent tree something
like:
BLOCKS:
(0-1):588791-588792, (0):588791
We need to move back to the previous extent prior
to modification, if we inserted a new one.

Add support for configure --enable-verbose-makecmds
Some people don't want to see the concise "kernel-style" make output.
This configure option allows build engines that want to see the full
set of commands executed by the makefile to get what they want. Most
people will find this more distracting than useful, unless they need
to debug the Makefiles.
(It is not necessary to rerun configure to enable this verbose make
output temprarily; if a developer wants to do a quick debug of a
directory's makefile, he or she can simply edit the definition of the
$(E) and $(Q) variables in the Makefile; instructions can be found in
the MCONFIG file which is included in at the beginning of every
Makefile.)

The e2fsprogs makefiles were using the same Makefile variable
LIBCOM_ERR for the link-line arguments as well as the dependencies.
Since LIBCOM_ERR can now include non-file arguments such as
"-lpthread", we need to use a separate DEPLIBCOM_ERR variable that
only has build file dependencies.

Fix encoding for rec_len in directories for >= 64k blocksize file systems
Previously e2fsprogs interpreted 0 for a rec_len of 65536 (which could
occur if the directory block is completely empty in 64k blocksize
filesystems), while the kernel interpreted 65535 to mean 65536. The
kernel will accept both to mean 65536, and encodes 65535 to be 65536.
This commit changes e2fsprogs to match.
We add the encoding agreed upon for 128k and 256k filesystems, but we
don't enable support for these larger block sizes, since they haven't

libext2fs: write only core inode in update_path()
The ext2_extent_handle only has a struct ext2_inode allocated on
it, and the same amount copied into it in that same function,
but in update_path() we're possibly writing out more than that -
for example 256 bytes, from that address. This causes uninitialized
memory to get written to disk, overwriting the parts of the
inode past the osd2 member (the end of the smaller structure).

libext2fs: Fix memory leak in the extents handling function
Each time an extent handle is opened and closed, if the inode has an
extent tree which does not fit in the inode's i_block structure, a
filesystem block buffer was not getting released. Since e2fsck opens
an extent handle for every inode using extents, this can translate to
a very large amount of memory getting lost.
Thanks to Henrik 'Mauritz' Johnson for discovering and pointing out
this leak, which he ran into while running the "rdump" command in
debugfs.

resize2fs: fix ENOSPC corruption case
http://people.redhat.com/esandeen/livecd-creator-imagefile.bz2
contains an image (for now) which, when resized to 578639, corrupts
the filesystem.
This is a bit crazy, I guess, because the fs currently has only
1 free block, but still, we should be graceful about the failure.
Perhaps it would make sense to check the requested valuea against
the minimum value resize2fs would compute for "-P" and fail (at
least without a force).
But in any case, this exposed 2 bugs when moving that one block
required an extent split, which is what hit the ENOSPC.
For starters, ext2fs_extent_set_bmap() in the "(re/un)mapping last
block in extent" case was replacing the old extent before the
new one was created; when the new extent creation failed, it
left us in an inconsistent state. Simply changing the order of
the two should fix this problem.
Next, ext2fs_extent_insert was calling ext2fs_extent_delete()
on *any* error, including one caused by failure to allocate a new
block to split the node to hold that extent ... the handle was left
unchanged, and we deleted the -original- extent.
As a quick fix for this, just don't do the delete if we fail the split,
though this may need to be smarter. I don't think we have terribly
consistent behavior about where a handle is left on various errors.

portability standpoint, fear not. This has been beaten to death
in other forums. Here are a few threads:
http://thread.gmane.org/gmane.comp.version-control.git/74187
http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/12712
http://thread.gmane.org/gmane.emacs.devel/98144
http://thread.gmane.org/gmane.comp.lib.glibc.alpha/13092
There has been debate about whether it's a good idea from a
performance standpoint, too, but imho you'll have a hard time
finding an instance where this sort of change induces a
measurable performance penalty. If you do, please let me know.

libext2fs: Add sanity checks to ext2fs_{block,inode}_alloc_stats
If ext2fs_inode_alloc_stats2() or ext2fs_block_alloc_stats() is passed
an insanely large inode or block number, it's possible for these
functions to overrun an array boundary and cause the calling program
to crash with a memory error.
Detect this case, and since these functions don't return an error
code, print a warning message, much like we do in ext2fs_warn_bitmap2().

Create the journal in the middle of the filesystem
This speeds up access to the journal by eliminating worst-case seeks
from one end of the disk to another, which can be quite common in very
fsync-intensive workloads if the file is located near the end of the
disk, and the journal is located the beginning of the disk.
In addition, this can help eliminate journal fragmentation when
flex_bg is enabled, since the first block group has a large amount of
metadata.

libext2fs: Don't check the group checksum when !GDT_CSUM
ext2fs_group_desc_csum_verify() is always checking the bg_checksum (to
make sure it is zero) even when the GDT_CSUM feature is not present.
This is normally OK, but apparently there are filesystems in the wild
where this field has not be initialized to zero.

Define _XOPEN_SOURCE to 600 consistently for Solaris C99 support
Solaris's header files are very picky about which C compiler can be
used for SUSv3 conformance. Use of C99 is not compatible with SUSv2
(_XOPEN_SOURCE=500), and C89 is not compatible with SUSv3
(_XOPEN_SOURCE=600). Since we need some SUSv3 functions, consistently
use SUSv3 so that e2fsprogs will build on Solaris using c99.

Make ext2fs_check_desc() more stringent to force use of backup superbocks
E2fsck could to do more damage to a filesystem by trying to relocate
inode tables due to corrupted block group descriptors, and the
relocation could seriously damage the filesystem.
This patch enhances ext2fs_check_desk() so it detects more
self-inconsistent block group descriptors, including the cases where
e2sck might be tempted to relocate the inode table, and reports the
block group descriptors as invalid; this will cause e2fsck to attempt
to use the backup superblocks, which hopefully have not been trashed.

When called for a given handle, the new function extent_node_split()
will split the current node such that half of the node's entries will
be moved to a new tree block. The parent will then be updated to
point to the (now smaller) original node as well as the new node.
If the root node is requested to be split, it will move all
entries out to a new node, and leave a single entry in the
root pointing to that new node.
If the reqested split node's parent is full it will recursively
split up to the root to make room for the new node's insertion.
If you ask to split a non-root node with only one entry,
it will refuse (we'd have an empty node otherwise).
It also updates the i_blocks count when a new block has
successfully been connected to the tree.

It used to be the case that ext2fs_set_gdt_csum set the ITABLE_ZEROED
flag if the INODE_UNINIT is not set. This assumed that the only
caller of ext2fs_set_gdt_csum was e2fsck (which was not true), and
that e2fsck would take care of zeroing the inode table (whic was also
not true).

libext2fs: Fix resize inode creation with non-standard s_first_data_block
Thanks to Max Lindner (lokimuh) for pointing this out.
I'm playing around a bit with ext2 and multi-user encryption and I
need space for my key management. So I set s_first_data_block to 4000
or something like that.
This way mke2fs segfaults when executing
ext2fs_create_resize_inode() because
blk_t goal = 3 + sb->s_reserved_gdt_blocks + fs->desc_blocks +
fs->inode_blocks_per_group;
will produce a integer underrun later and segfault then in the
ext2fs_test_bit assembler inline function.
when exchanging 3 with 2 + sb->s_first_data_block, mke2fs does not
segfault.
I'm not 100% sure if thats the correct way dealing with this issue
but I think its a proper solution.

Add support for the DIR_NLINK feature.
This patch includes the changes required to e2fsck to understand the
nlink count changes made in the kernel.
In e2fsck pass 4, when we fetch the actual link count, if it is
exceeds 65,000 we set the link count to 1. We silently fix the
situation where the nlink count of the directory is 1, and there are
fewer than 65,000 subdirectories, since since that can happen
naturally.
Patch originally from CFS, significantly rewritten by Theodore Ts'o.

libext2fs: Make icount use a 32-bit counter
In order to more accurately count the number of directories, which
with the DIR_NLINKS feature can now be greater than 65,000, change
icount to use a 32-bit counter. This doesn't cost us anything extra
when the icount data structures are stored in memory, since due to
padding for alignment reasons.
If the actual count is greater than 65,500, we return 65,500. This is
because e2fsck doesn't actually need to know the exact count; it only
needs to know if the number of subdirectories is greater than 65,000.
In the future if someone really needs to know the exact number, we
could add a 32-bit interface. One isn't needed now, though.

Fix ext2fs_swap_inode_full() for in-inode xattrs on big-endian machines
After the fix for resize2fs's inode mover losing in-inode
extended attributes, the regression test I wrote caught
that the attrs were still getting lost on powerpc.
Looks like the problem is that ext2fs_swap_inode_full()
isn't paying attention to whether or not the EA magic is
in hostorder, so it's not recognized (and not swapped)
on BE machines. Patch below seems to fix it.
Yay for regression tests. ;)

Don't byte swap extents information in the inode
Responsibility for byte swapping the extents information rests with
the low-level extent code, which translates the on-disk extents
information to the abstract extent format. The on-disk format will
eventually get more complicated, in order to add support for 64-bit
block numbers, bit-compressed extents, etc. So to avoid needing to
expose all of that complexity in swapfs.c, the in-memory contents of
i_blocks will not be byte-swapped and will be identical to the on-disk
format.

Use lseek() instead of llseek() of sizeof(long) == sizeof(long long)
Previously we used a hard-coded test where for the Alpha and the IA64,
we used lseek instead of llseek(). Generalize this to whenver
sizeof(long) is the same as sizeof(long long).
It turns out this fixes a FTBFS problem on the x86_64 for Debian,
since dietlibc doesn't provide llseek() on that architecture.

it will be removed from the primary superblock either when the

libext2fs: Add checks to prevent integer overflows passed to malloc()
This addresses a potential security vulnerability where an untrusted
filesystem can be corrupted in such a way that a program using
libext2fs will allocate a buffer which is far too small. This can
lead to either a crash or potentially a heap-based buffer overflow
crash. No known exploits exist, but main concern is where an
untrusted user who possesses privileged access in a guest Xen
environment could corrupt a filesystem which is then accessed by the
pygrub program, running as root in the dom0 host environment, thus
allowing the untrusted user to gain privileged access in the host OS.
Thanks to the McAfee AVERT Research group for reporting this issue.

really bad things can happen when are deleting the first directory
entry in a block where the last directory entry in the previous

the current entry is not the first one in the block before trying to

ext2fs_dblist_dir_iterate: Fix ABORT propagation logic
ext2fs_dblist_dir_iterate() calls ext2fs_dblist_iterate(), which calls
ext2fs_process_dir_block(), which in turn calls the helper function
db_dir_proc() which calls callback function passed into
ext2fs_dblist_dir_iterate(). At each stage the conventions for
signalling requests to abort the iteration or to signal errors
changes, db_dir_proc() was not properly mapping the abort request back
to ext2fs_dblist_iterate().
Currently db_dir_proc() is ignoring errors (i/o errors or directory
block corrupt errors) from ext2fs_process_dir_block(), since the main
user of ext2fs_dblist_dir_iterate() is e2fsck, for which this is the
correct behavior. In the future ext2fs_dblist_dir_iterate() could
take a flag which would cause it to abort if
ext2fs_process_dir_block() returns an error; however, it's not clear
how useful this would be since we don't have a way of signalling the
exact nature of which block had the error, and the caller wouldn't
have a good way of knowing what percentage of the directory block list
had been processed. Ultimately this may not be the best interface for
applications that need that level of error reporting.

this problem.

Fix test in ext2fs_check_desc() for inode table within block group
The test in ext2fs_check_desc() is off by one; if the inode table
goes all the way to the last block of the block group, it will
falsely assert that it has extended past it. The last block
of a range is start + len -1, not start + len.
You can create (valid) filesystems that will cause e2fsck to complain
via one of the following mkfs commands:
mkfs.ext3 -F -b 1024 /dev/sdb1 2046000000
mke2fs -j -F -b 4096 -m 0 -N 5217280 /mnt/test/fsfile2 327680
mkfs.ext2 -F -b 1024 -m 0 -g 256 -N 3744 fsfile 1024

Properly calculate overhead in ext2fs_initialize()
For some odd geometries*, mkfs will try to allocate inode tables off
the end of the block group and fail, rather than warning that too
many inodes have been requested.
This is because when ext2fs_initialize calculates metadata overhead,
it is only adding in group descriptor blocks and the superblock
if the *last* bg contains them - but the first bg also has all of
the various metadata bits taking up space.
We need to calculate the overhead both for the first block group and
the last block groups separately, since the two different tests need
to know what the overheads are for those two cases, which may be
different.
*for example "mke2fs -b 1024 -m 0 -g 256 -N 3745 fsfile 1024"
(Note, the test here is a little funky; the expected output is
actually a mkfs failure - but a proper failure instead of the
allocator catching the problem at the last minute)

Don't write changes to the backup superblocks by default
This patch changes ext2fs_open() to set EXT2_FLAG_MASTER_SB_ONLY by
default. This avoids some problems in e2fsck (reported by Jim Garlick)
where a corrupt journal can end up writing the bad superblock to the
backups. In general, only e2fsck (after the filesystem is clean),
tune2fs, and resize2fs should change the backup superblocks by default.
Most callers of ext2fs_open() should not be touching anything where the
backups should be touched. So let's change the defaults to avoid
potential problems.

Reserve superblock fields for multiple mount protection feature
There have been reported instances of a filesystem having been mounted
at 2 places at the same time causing a lot of damage to the
filesystem. This patch reserves superblock fields and an INCOMPAT flag
for adding multiple mount protection(MMP) support within the ext4
filesystem itself. The superblock will have a block number
(s_mmp_block) which will hold a MMP structure which has a sequence
number which will be periodically updated every 5 seconds by a mounted
filesystem. Whenever a filesystem will be mounted it will wait for
s_mmp_interval seconds to make sure that the MMP sequence does not
change. To further make sure, we write a random sequence number into
the MMP block and wait for another s_mmp_interval secs. If the
sequence no. doesn't change then the mount will succeed. In case of
failure, the nodename, bdevname and the time at which the MMP block
was last updated will be displayed. tune2fs can be used to set
s_mmp_interval as desired.

Add directory hashed signed/unsigned hint to superblock
The e2fsprogs and kernel implementation of directory hash tree has a
bug which causes the implementation to be dependent on whether
characters are signed or unsigned. Platforms such as the PowerPC,
Arm, and S/390 have signed characters by default, which means that
hash directories on those systems are incompatible with hash
directories on other systems, such as the x86.
To fix this we add a new flags field to the superblock, and define two
new bits in that field to indicate whether or not the directory should
be signed or unsigned. If the bits are not set, e2fsck and fixed
kernels will set them to the signed/unsigned value of the currently
running platform, and then respect those bits when calculating the
directory hash. This allows compatibility with current filesystems,
as well as allowing cross-architectural compatibility.

Fix loops over group descriptors to prevent 2**32-1 block number overflows
For loops iterating over all group descriptors, consistently define
first_block and last_block in a way that they are inclusive of the
range, and do not overflow.
Previously on the last block group we did a test of <= first +
dec_blocks; this would actually wrap back to 0 for a total block count
of 2^32-1
Also add handling of last block group which may be smaller.

This feature is initially intended for testing purposes; it allows an
ext2/ext3 developer to create very large filesystems using sparse files
where most of the block groups are not initialized and so do not require
much disk space. Eventually it could be used as a way of speeding up
mke2fs and e2fsck for large filesystem, but that would be best done by
adding an RO_COMPAT extension to the filesystem to allow the inode table
to be lazily initialized on a per-block basis, instead of being entirely initialized
or entirely unused on a per-blockgroup basis.

Fix the i386 bitmap operations so they are 32-bit clean
The x86 assembly instructures for bit test-and-set, test-and-clear,
etc., interpret the bit number as a 32-bit signed number, which is
problematic in order to support filesystems > 8TB.
Added new inline functions (in C) to implement a
ext2fs_fast_set/clear_bit() that does not return the old value of the
bit, and use it for the fast block/bitmap functions.
Added a regression test suite to test the low-level bit operations
functions to make sure they work correctly.
Note that a bitmap can address 2**32 blocks requires 2**29 bytes, or
512 megabytes. E2fsck requires 3 (and possibly 4 block bitmaps),
which means that the block bitmaps can require 2GB all by themselves,
and this doesn't include the 4 or 5 inode bitmaps (which assuming an
8k inode ratio, will take 256 megabytes each). This means that it's
more likely that a filesystem check of a filesystem greater than 2**31
blocks will fail if the e2fsck is dynamically linked (since the shared
libraries can consume a substantial portion of the 3GB address space
available to x86 userspace applications). Even if e2fsck is
statically linked, for a badly damaged filesystem, which may require
additional block and/or inode bitmaps, I am not sure e2fsck will
succeed in all cases.

ext2fs_resize_mem() is suffering from C99 strict type aliasing problems.
The trouble is that it is modifying pointers in place, but doing so via
"void *" types which alias the pointers passed in (which are typically
pointers to a struct.) The inline ext2fs_resize_mem() code may update
the pointer, but the caller is not required to reload the old value it
may have cached in a register, according to the type aliasing rules.
This is causing the caller to dereference the old pointer when compiled
with -O2, resulting in reproducible SEGV, on at least one ia64
configuration.
The compiler *is* required to reload if it sees an update to a dereferenced
char value, though, as chars are defined to alias anything; and memcpy()
is defined to operate on chars. So using memcpy() to copy the pointer
values is guaranteed to force the caller to reload. This has been
verified to fix the problem in practice.
Fixes Red Hat bug #161183.

Add paranoia checks into the blkid, ext2fs, and ss libraries to ignore
environment variables if the libraries are called from setuid or setguid
programs, or if kernel believes that the process is not eligible to create
a core dump. In addition, if the libc has __secure_getenv(), use it so that
the libc can also do any additional limitations regarding when libraries can
trust environment variables (i.e., to integrate with systems like SELinux
and Posix capabilities).

Fix e2fsck, debugfs, and the ext2fs_mkdir function so that when we create
a new inode we make sure that the extra information in the inode (any extra
fields in a large inode and any ea-in-inode information) is cleared. This
can happen when e2fsck creates a new root inode or a new lost+found directory,
or when the user uses the debugfs write, mknod, or mkdir commands. Otherwise,
the newly create inode could inherit garbage (or old EA information) from
a previously deleted inode.

Add support for backing up the journal inode location in the
superblock. E2fsck will automatically save the journal information
in the superblock if it is not there already, and will use it if the
journal inode appears to be corrupted. ext2fs_add_journal_inode()
will also save the backup information, so that new filesystems
created by mke2fs and filesystems that have journals added via
tune2fs will also have journal location written to the superblock as
well. Debugfs's logdump command has been enhanced so that it can
use the journal information in the superblock.
The debugfs man page has been improved to more fully describe the
logdump command.
Added two new functions, ext2fs_file_open2() and
ext2fs_inode_io_intern2() which take a pointer to an inode structure;
this is needed so that e2fsck and debugfs can synthesize a
fake journal inode and use it to access the journal.

Fix bug in resize2fs which caused it to fail on filesystems with a
non-empty bad block list. Resize2fs now discards any blocks on the
badblock list which are no longer part of the filesystem as the result
of a filesystem shrink. (Note: this means that shrinking and then
enlarging a filesystem is no longer a reversible operation;
information about bad blocks in the part of the filesystem
which is to be chopped off will be lost.)

unix_io.c (unix_open): Only attempt the setrlimit workaround if

doesn't need to be byte swapped --- except if an
old-style kernel had byte-swapped the name_len field
as part of the V1 structure.
Also fixed a bug in debugfs which used ext2_dir_entry_2 without
worrying about the above issue, with the net result that "ls -l"
would print an incorrect file type on big-endian systems.

Fixes necessary for e2fsprogs to work using the diet libc.
- Renamed linux/list.h to be linux/linked_list.h to work around a
problem caused by diet libc insistence to search the kernel
header files ahead of all other files in the include path,
including the user specified include files.
- Worked around a bug in diet libc which core dumps when using
putc with stderr by using fputs instead. As a bonus, this
also shaved a few bytes off of com_err.o.
- Fixed a real bug in debugfs which was detected because diet libc
was more sensitive than glibc when incorrectly using fclose()
where pclose() is required.

Speed up journal recovery in userspace by avoiding a pointless
unconditional ext2_flush() call. Also made ext2_flush() more
efficient when the superblock is modified after the filesystem has
been flushed, and make it clear the superblock dirty flag
after doing the superblock/block group descriptor flush.

ChangeLog, ext2_err.et.in, ext2fs.h, initialize.c, mkjournal.c, openfs.c:
initialize.c (ext2fs_initialize): Add support for initializing the
ext2 superblock for external journal devices. This basically means we
don't bother to allocate any block group descriptors.
openfs.c (ext2fs_open): Only open external journal devices if the new
flag EXT2_FLAG_JOURNAL_DEV_OK is passed to ext2fs_open. When opening
such devices, don't try to read the block group descriptors, since
they're not there.
ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
mkjournal.c: Export a new function,
ext2fs_create_journal_superblock(), which allocates and returns a
buffer containing a journal superblock. This is needed by mke2fs to
create an external journal. Rewrote ext2fs_add_journal_device() so
that it no longer creates the external journal, but rather adds a
filesystem to an existing external journal. It handles all of the
UUID manipulation.
ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported by the

ChangeLog, debug_cmds.ct, debugfs.8.in, debugfs.c, dump.c, ls.c:
debugfs.8.in: Documented new behaviour.
ls.c (ls_l_file): Fix Y2K bug -- was printing 22-May-100 for recent
files. Switched to 4-digit years.
dump.c, debug_cmds.ct (do_rdump): Add new debugfs command "rdump",
which recursively dumps a directory and its contents.
(fix_perms): New function. Break permission-fixing code out of
dump_file() so it can be called by rdump code as well.
(dump_file): Call fix_perms().
debugfs.c, debug_cmds.ct (do_lcd): Add new debugfs command "lcd",
which changes the cwd on the native filesystem.
debugfs.c (open_filesystem): Extra args for superblock, blocksize, and
catastrophic mode. Changed callers.
(do_open_filesys, main): Accept new -b, -s, -c options for
open_filesystem.
ChangeLog, mkdir.c:

ChangeLog, pass3.c:
pass3.c (check_directory): Only do the loop detection algorithm if
we've searched over 2048 parent directories and haven't found the end

the inode_loop_detection bitmap, which for large systems, merely
clearing the bitmap for each directory was turning out to be quite
expensive. Thanks to Jani Jaakkola (jjaakkol@cs.helsinki.fi) for

Many files:

bitmap, don't check to see if it is disconnected from the inode tree
(because it almost certainly will be). Free inode_imagic_map at the
end of pass 4.
pass2.c (check_dir_block, check_filetype): If the FILETYPE feature is
set, check the directory entry's filetype information field, and
fix/set it if necessary. (e2fsck_pass2): Free the inode_reg_map
bitmap at the end of pass 2.
pass1.c (e2fsck_pass1, alloc_imagic_map): Allocate and fill in
information for inode_reg_map and inode_imagic_map, which indicates
which inodes are regular files and AFS inodes, respectively.
Since only the master superblock is written during a restart, force
that superblock to be used after a restart; otherwise changes to the
block group descriptors end up getting ignored.
problem.c, problemP.h: If e2fsck is run -n, make def_yn variable be 0

ChangeLog, Makefile.in, bmap.c, bmove.c, ext2fs.h, jump.funcs:
ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform with
32 bit longs, then we need to manually define __s64 and __u64, since
the current kernel header files don't define these if __STRICT_ANSI__
is defined. This is a problem if we are compiling with full GCC
warnings, since we do need 64 bit support.

llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype to
make life easer for GNU Libc 2.
rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
filesystem has its bitmaps stored as 32-bit words with bit 0 as the
LSB of each word. Thus a bitmap with only bit 0 set would be, as a
string of bytes, 00 00 00 01 00 ... To cope with this, we
byte-reverse each word of a bitmap if we have a big-endian filesystem,
that is, if we are *not* byte-swapping other word-sized numbers.
