Upgrade to valgrind 3.13.0 (15 June 2017).
Release 3.13.0 (15 June 2017)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.13.0 is a feature release with many improvements and the usual collection of
bug fixes.
This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux,
PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux,
MIPS64/Linux, ARM/Android, ARM64/Android, MIPS32/Android, X86/Android,
X86/Solaris, AMD64/Solaris and AMD64/MacOSX 10.12.
* ==================== CORE CHANGES ===================
* The translation cache size has been increased to keep up with the demands of
large applications. The maximum number of sectors has increased from 24 to
48. The default number of sectors has increased from 16 to 32 on all
targets except Android, where the increase is from 6 to 12.
* The amount of memory that Valgrind can use has been increased from 64GB to
128GB. In particular this means your application can allocate up to about
60GB when running on Memcheck.
* Valgrind's default load address has been changed from 0x3800'0000 to
0x5800'0000, so as to make it possible to load larger executables. This
should make it possible to load executables of size at least 1200MB.
* A massive spaceleak caused by reading compressed debuginfo files has been
fixed. Valgrind should now be entirely usable with gcc-7.0 "-gz" created
debuginfo.
* The C++ demangler has been updated.
* Support for demangling Rust symbols has been added.
* A new representation of stack traces, the "XTree", has been added. An XTree
is a tree of stacktraces with data associated with the stacktraces. This is
used by various tools (Memcheck, Helgrind, Massif) to report on the heap
consumption of your program. Reporting is controlled by the new options
--xtree-memory=none|allocs|full and --xtree-memory-file=<file>.
A report can also be produced on demand using the gdbserver monitor command
'xtmemory [<filename>]>'. The XTree can be output in 2 formats: 'callgrind
format' and 'massif format. The existing visualisers for these formats (e.g.
callgrind_annotate, KCachegrind, ms_print) can be used to visualise and
analyse these reports.
Memcheck can also produce XTree leak reports using the Callgrind file
format. For more details, see the user manual.
* ================== PLATFORM CHANGES =================
* ppc64: support for ISA 3.0B and various fixes for existing 3.0 support
* amd64: fixes for JIT failure problems on long AVX2 code blocks
* amd64 and x86: support for CET prefixes has been added
* arm32: a few missing ARMv8 instructions have been implemented
* arm64, mips64, mips32: an alternative implementation of Load-Linked and
Store-Conditional instructions has been added. This is to deal with
processor implementations that implement the LL/SC specifications strictly
and as a result cause Valgrind to hang in certain situations. The
alternative implementation is automatically enabled at startup, as required.
You can use the option --sim-hints=fallback-llsc to force-enable it if you
want.
* Support for OSX 10.12 has been improved.
* On Linux, clone handling has been improved to honour CLONE_VFORK that
involves a child stack. Note however that CLONE_VFORK | CLONE_VM is handled
like CLONE_VFORK (by removing CLONE_VM), so applications that depend on
CLONE_VM exact semantics will (still) not work.
* The TileGX/Linux port has been removed because it appears to be both unused
and unsupported.
* ==================== TOOL CHANGES ====================
* Memcheck:
- Memcheck should give fewer false positives when running optimised
Clang/LLVM generated code.
- Support for --xtree-memory and 'xtmemory [<filename>]>'.
- New command line options --xtree-leak=no|yes and --xtree-leak-file=<file>
to produce the end of execution leak report in a xtree callgrind format
file.
- New option 'xtleak' in the memcheck leak_check monitor command, to produce
the leak report in an xtree file.
* Massif:
- Support for --xtree-memory and 'xtmemory [<filename>]>'.
- For some workloads (typically, for big applications), Massif memory
consumption and CPU consumption has decreased significantly.
* Helgrind:
- Support for --xtree-memory and 'xtmemory [<filename>]>'.
- addition of client request VALGRIND_HG_GNAT_DEPENDENT_MASTER_JOIN, useful
for Ada gnat compiled applications.
* ==================== OTHER CHANGES ====================
* For Valgrind developers: in an outer/inner setup, the outer Valgrind will
append the inner guest stacktrace to the inner host stacktrace. This helps
to investigate the errors reported by the outer, when they are caused by the
inner guest program (such as an inner regtest). See README_DEVELOPERS for
more info.
* To allow fast detection of callgrind files by desktop environments and file
managers, the format was extended to have an optional first line that
uniquely identifies the format ("# callgrind format"). Callgrind creates
this line now, as does the new xtree functionality.
* File name template arguments (such as --log-file, --xtree-memory-file, ...)
have a new %n format letter that is replaced by a sequence number.
* "--version -v" now shows the SVN revision numbers from which Valgrind was
built.
* ==================== FIXED BUGS ====================
The following bugs have been fixed or resolved. Note that "n-i-bz"
stands for "not in bugzilla" -- that is, a bug that was reported to us
but never got a bugzilla entry. We encourage you to file bugs in
bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
than mailing the developers (or mailing lists) directly -- bugs that
are not entered into bugzilla tend to get forgotten about or ignored.

Upgrade to valgrind 3.12.0.
Release 3.12.0 (20 October 2016)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.12.0 is a feature release with many improvements and the usual
collection of bug fixes.
This release supports X86/Linux, AMD64/Linux, ARM32/Linux,
ARM64/Linux, PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux,
MIPS32/Linux, MIPS64/Linux, ARM/Android, ARM64/Android,
MIPS32/Android, X86/Android, X86/Solaris, AMD64/Solaris, X86/MacOSX
10.10 and AMD64/MacOSX 10.10. There is also preliminary support for
X86/MacOSX 10.11/12, AMD64/MacOSX 10.11/12 and TILEGX/Linux.
* ================== PLATFORM CHANGES =================
* POWER: Support for ISA 3.0 has been added
* mips: support for O32 FPXX ABI has been added.
* mips: improved recognition of different processors
* mips: determination of page size now done at run time
* amd64: Partial support for AMD FMA4 instructions.
* arm, arm64: Support for v8 crypto and CRC instructions.
* Improvements and robustification of the Solaris port.
* Preliminary support for MacOS 10.12 (Sierra) has been added.
Whilst 3.12.0 continues to support the 32-bit x86 instruction set, we
would prefer users to migrate to 64-bit x86 (a.k.a amd64 or x86_64)
where possible. Valgrind's support for 32-bit x86 has stagnated in
recent years and has fallen far behind that for 64-bit x86
instructions. By contrast 64-bit x86 is well supported, up to and
including AVX2.
* ==================== TOOL CHANGES ====================
* Memcheck:
- Added meta mempool support for describing a custom allocator which:
- Auto-frees all chunks assuming that destroying a pool destroys all
objects in the pool
- Uses itself to allocate other memory blocks
- New flag --ignore-range-below-sp to ignore memory accesses below
the stack pointer, if you really have to. The related flag
--workaround-gcc296-bugs=yes is now deprecated. Use
--ignore-range-below-sp=1024-1 as a replacement.
* DRD:
- Improved thread startup time significantly on non-Linux platforms.
* DHAT
- Added collection of the metric "tot-blocks-allocd"
* ==================== OTHER CHANGES ====================
* Replacement/wrapping of malloc/new related functions is now done not just
for system libraries by default, but for any globally defined malloc/new
related function (both in shared libraries and statically linked alternative
malloc implementations). The dynamic (runtime) linker is excluded, though.
To only intercept malloc/new related functions in
system libraries use --soname-synonyms=somalloc=nouserintercepts (where
"nouserintercepts" can be any non-existing library name).
This new functionality is not implemented for MacOS X.
* The maximum number of callers in a suppression entry is now equal to
the maximum size for --num-callers (500).
Note that --gen-suppressions=yes|all similarly generates suppressions
containing up to --num-callers frames.
* New and modified GDB server monitor features:
- Valgrind's gdbserver now accepts the command 'catch syscall'.
Note that you must have GDB >= 7.11 to use 'catch syscall' with
gdbserver.
* New option --run-cxx-freeres=<yes|no> can be used to change whether
__gnu_cxx::__freeres() cleanup function is called or not. Default is
'yes'.
* Valgrind is able to read compressed debuginfo sections in two formats:
- zlib ELF gABI format with SHF_COMPRESSED flag (gcc option -gz=zlib)
- zlib GNU format with .zdebug sections (gcc option -gz=zlib-gnu)
* Modest JIT-cost improvements: the cost of instrumenting code blocks
for the most common use case (x86_64-linux, Memcheck) has been
reduced by 10%-15%.
* Improved performance for programs that do a lot of discarding of
instruction address ranges of 8KB or less.
* The C++ symbol demangler has been updated.
* More robustness against invalid syscall parameters on Linux.
* ==================== FIXED BUGS ====================
The following bugs have been fixed or resolved. Note that "n-i-bz"
stands for "not in bugzilla" -- that is, a bug that was reported to us
but never got a bugzilla entry. We encourage you to file bugs in
bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
than mailing the developers (or mailing lists) directly -- bugs that
are not entered into bugzilla tend to get forgotten about or ignored.

Adds initial support for AArch64 (arm64) on Android. Small programs
(/system/bin/ls, /system/bin/date) run. Still to do:
* enable more malloc/free intercepts
* enable wrappers for ashmem and binder syscalls
* check to see if any special ioctl support is required for ARM Mali GPUs

Prepare to change the default for --read-inline-info from =no to =yes
The interception/replacements functions should preferrably not
depend on the value of --read-inline-info.
The idea is to change the default from no to yes.
Depending on the no or yes, some intercept/replacement functions
that are inlined will be shown or not shown in stacktraces.
To have such stack traces not depending on the value of --read-inline-info,
such functions should either be marked as
noinline
or be defined as macros.

Solve false negative for various malloc replaced functions arguments
The replacement functions are running on the simulated CPU.
The code on the simulated CPU does not necessarily use
all arguments. E.g. args can be ignored and/or only given
to a NON SIMD call.
The definedness of such 'unused' arguments will not be verified
by memcheck.
A call to 'trigger_memcheck_error_if_undefined' allows
memcheck to detect such errors for the otherwise unused args.
Apart of allowing memcheck to detect an error, the function
trigger_memcheck_error_if_undefined has no effect and
has a minimal cost for other tools replacing malloc functions.
(suggestion of the 'no operation check' from Julian).
tested on f12/x86, debian6/amd64, f18/ppc64
Note that some Darwin specific code has been modified
in coregrind/m_replace_malloc/vg_replace_malloc.c.
(Some of) this code has not been compiled (no access to a
Darwin system). The code changed is trivial, so there is
some chance it will compile and even maybe work.
Added a new test verifying that various malloc related
functions undefined args are triggering an error in memcheck.

fix 219156 support static malloc or alternate malloc lib (e.g. tcmalloc) with new option --soname-synonyms
* pub_tool_redir.h : define the prefix to be used for "soname synonym"
place holder
* vg_replace_malloc.c : define synonym place holder for malloc related
functions
* m_redir.c : when detecting a soname synonym place holder redir spec, search
in clo_soname_synonyms if there is a synonym pattern.
If yes, replace the soname pattern. If not, ignore the redir spec.
* various files: implement or document the new clo --soname-synonyms
* new test memcheck/tests/static_malloc.vgtest

Add initial support for Mac OS X 10.7 (Lion). Tracked by bug #275168.
* configure.in support
* new supp file darwin11.supp
* comment out many intercepts in mc_replace_strmem.c and
vg_replace_malloc.c that are apparently unnecessary for Darwin
* add minimal handling for the following new syscalls and mach traps:
mach_port_set_context
task_get_exception_ports
getaudit_addr
psynch_mutexwait
psynch_mutexdrop
psynch_cvbroad
psynch_cvsignal
psynch_cvwait
psynch_rw_rdlock
psynch_rw_wrlock
psynch_rw_unlock
psynch_cvclrprepost
* wqthread_hijack on amd64-darwin: deal with
tst->os_state.pthread having an apparently different offset,
which caused an assertion failure
* m_debuginfo: for 32 bit processes on Lion, use the DebugInfoFSM
cleanup added in r12041/12042 to handle apparently new dyld
behaviour, which is to map text areas r-- first and only
vm_protect them later to r-x.
The following cleanups remain to be done
* remove apparently pointless, commented out wrapper macro
invokations in mc_replace_strmem.c, eg
//MEMMOVE(VG_Z_DYLD, memmove)
(or determine that they are still necessary, and uncomment)
* ditto in vg_replace_malloc.c, plus general VGO_darwin cleanups
there
* write proper syscall wrappers for
mach_port_set_context
task_get_exception_ports
getaudit_addr
psynch_mutexwait
psynch_mutexdrop
psynch_cvbroad
psynch_cvsignal
psynch_cvwait
psynch_rw_rdlock
psynch_rw_wrlock
psynch_rw_unlock
psynch_cvclrprepost
These are currently just no-ops and may be causing Memcheck to
report false undef-value errors
* figure out why it doesn't work properly unless built with gcc-4.2 on
Lion.
gcc-4.2 is the "normal" gcc (i686-apple-darwin11-gcc-4.2.1). Plain
gcc is the hybrid gcc-front-end clang-back-end thing
(i686-apple-darwin11-llvm-gcc-4.2). Whereas on Snow Leopard, plain
gcc is the normal gcc.
The symptoms of the failure are that wqthread_hijack in
syswrap-amd64-linux.c hits this /*NOTREACHED*/ vg_assert(0); right
at the end (you need a pretty complex threaded app to trigger this),
which makes me think that either ML_(wqthread_continue_NORETURN) or
call_on_new_stack_0_1 do return, which they are not expected to.
* figure out if some of the uninitialised value errors reported in
system libraries on are caused by Memcheck being confused by LLVM
generated code, as per bug #242137

For intercepts in libc and the dynamic linker (ld.so or dyld), split
the Linux and Darwin definitions so they are in completely separate
ifdefs -- iow, remove any definitions that are common to both. This
gives some duplication, but the upside is that it is now possible to
edit the Darwin intercepts without fear of breaking the Linux ones.
This will be important when it comes to supporting OSX 10.7.

Extend the behavioural-equivalence-class mechanism for redirection
functions to include the ability to give a priority to each function,
as well as a tag indicating its behavioural class. Add logic in
m_redir.c to resolve conflicting redirections with the same eclass but
different priorities by preferring the redirection with the higher
priority. Use all of the above in mc_replace_strmem.c, to cause a
conflict between redirections for "memcpy" and "memcpy@GLIBC_2.2.5" to
be resolved in favour of the latter (the non-overlap-checking
version).
This is all related to the massive swamp that is #275284.

Fix for #275284 (initial fix, at least). Will break OSX; fix
to follow.
* add behavioural eclass tags for most functions in
mc_replace_strmem.c and vg_replace_malloc.c.
* add a wrapper for strspn() (see bug 270925)
* coregrind/m_redir.c: add logic to use eclass tags for
resolving conflicting redirections. Improve debug
printing in that situation.
* mc_replace_strmem.c: add a wrapper for "__GI___strcasecmp_l".
Gark. Is this correct? Does __GI___strcasecmp_l behave the
same as __GI_strcasecmp_l and strcasecmp_l ?

Get rid of the remaining "set but not used" warnings reported by gcc 4.6 by
swapping the roles of the VALGRIND_DO_CLIENT_REQUEST() and
VALGRIND_DO_CLIENT_REQUEST_EXPR() macros. Also, many __attribute__((unused))
declarations on variables have been eliminated. Closes #269778.
Note: so far this patch has been tested on x86/Linux, amd64/Linux and
ppc64/Linux but not yet on any other supported CPU/OS combination.

Remove some fluff detected by llvm-2.8 (clang):
- "*(int *)0 = " is apparently ignored by LLVM for who-knows-why
reason. Cast the zero to a volatile int * instead.
- remove an unused function that gcc failed to mention was unused
(why? because it was marked __attribute__((noreturn)) ?)
As an aside, clang/llvm-2.8 seemed to be able to successfully
compile Valgrind.

With the recent VG_(message) change,
VALGRIND_{PRINTF,PRINTF_BACKTRACE,INTERNAL_PRINTF} were no longer appending
newlines. This meant that --trace-malloc=yes spewed everything onto a
single line, among other things.
Rather than adding the newline back in, I chose to offically change their
behaviour to not add the newlines, as this is more flexible (and the reason
for the underlying VG_(message) change). I updated all the relevant places
I could find.

Merge the DARWIN branch onto the trunk.
I tried using 'svn merge' to do the merge but it did a terrible job and
there were bazillions of conflicts. So instead I just took the diff between
the branch and trunk at r10155, applied the diff to the trunk, 'svn add'ed
the added files (no files needed to be 'svn remove'd) and committed.

Make Memcheck work sanely on AIX5.3 (again):
* Don't intercept putenv/getenv/setenv. Causes a lot of whinging
about missing TOC pointers.
* Add 'strcmp' to the bundle of 4 functions intercepted in all
objects.
* xlc now seems to route calls through to malloc_common, free_common,
calloc_common, realloc_common, memalign_common in libc. Intercept
those names too.

Create a new module, m_vki, and move all knowledge about the kernel
interface, except for the syscall numbers, into that. Mostly this
means moving include/vki-*.h to include/vki/vki-*.h.
include/pub_tool_basics.h previously dragged in the entire kernel
interface. I've done away with that, so that modules which need to
see the kernel interface now have to include pub_{core,tool}_vki.h
explicitly. This is why there are many modified .c files -- they have
all acquired an extra #include line.
This certainly breaks all platforms except x86. Will fix shortly.

Final commit for the initial modularisation pass:
- Broke part of m_scheduler off into a new module m_threadstate. It
contains ThreadState, VG_(threads)[] and some basic operations on the
thread table. All simple stuff, the complex stuff stays in m_scheduler.
This avoids lots of circular dependencies between m_scheduler and other
modules.
- Managed to finally remove core.h and tool.h, double hurrah!
- Introduced pub_tool_basics.h and pub_core_basics.h, one of which is
include by every single C file.
- Lots of little cleanups and changes related to the above.
- I even did a small amount of documentation updating.

A cleanup of the redirection stuff.
- Renamed VG_INTERCEPT as VG_REPLACE_FUNCTION to make its purpose
clearer.
- Renamed VG_WRAPPER as VG_NOTIFY_ON_LOAD to make its purpose cleare.
Started calling that stuff "load notification".
- Moved various things into m_redir.c, a much more sensible place for
them. This reduced the number of exported functions overall. Renamed
intercept_demangle() as Z_decode() as part of this.
- Improved the documentation of this stuff, especially in
pub_core_redir.c.
- Got --run-libc-freeres=yes working again. It was doing nothing.
- Renamed vg_inject.so as vg_preload_core.so to match
vg_preload_<tool>.so
- Renamed vg_intercept.c as vg_preloaded.c. (I kept the "vg_" prefix
because this filename can appear in stack traces, so the "vg_" is a
useful hint for users that it belongs to Valgrind.)
- Removed all the Memcheck-specific calls to add_redirect_sym_to_sym()
from VG_(setup_redirect_table)(), instead using VG_REPLACE_FUNCTION in
mac_replace_strmem.c, just like vg_replace_malloc.c. This is the
right way to do it. This required moving some of
coregrind/pub_core_redir.h into the newly added
include/pub_tool_redir.h. add_redirect_sym_to_sym() is no longer
used...
- Now only handing off symbols to m_redir for inspection/decoding after
they have been deemed to be interesting by the symbol table reader.
- Factored out commonality between the add_redirect_*_to_* functions
into add_redirect_X_to_X().
- Added "Zh", meaning '-' ('h' for "hyphen"), to the Z-decoding scheme,
to handle sonames like "ld-linux-x86-64.so.2".
- Added a FAQ explaining the newly found issue of glibc aliasing
sometimes causing the wrong function name to appear in stack traces.
- Added a new regtest strchr.c. It's possible this will fail on some
platforms. If so, an alternative output file can be provided, but
I'd like to see it in practice first.
It's possible that there will be minor breakage on other
platforms/setups, but it should be minimal and easily fixable.
Plus some ordinary cleanups in symtab.c:
- Removed the old optimisation from VG_(addStr)() whereby it kept track
of the previous 5 added strings and avoiding duplicating any of them.
Turns out it was barely having any effect any more, and just
complicated things.
- Made read_symtab() more readable, by introducing a new variable
"sym_name" and introducing the auxiliary function
is_symbol_interesting().
- renamed the module variable 'segInfo' as 'segInfo_list' to make it
more obvious it's a module variable and not just some ordinary local
variable (which was an easy mistake to make).
-----------------------------------------------------------------------------
XXX: [later] remove add_redirect_sym_to_sym, and everything related to
X_to_sym? (ie. only need X_to_addr)
XXX: better function names? all those 'resolved' names...
[later...]

Modularised the malloc/free stuff into two modules: m_mallocfree for the
malloc/free implementation, and m_replacemalloc with the stuff for the tools
that replace malloc with their own version. Previously these two areas of
functionality were mixed up somewhat.
