Add private data field to struct tcb
We need to be able to store private data in the struct tcb across it's
lifetime. To ensure proper deallocation of this stored data a callback
must be provided along with the data. The callback is executed
automatically on exiting syscall, and when the life of the tcb ends.

Fix SYS_FUNC and SEN macros for musl
The syscall_name argument was subject to macro expansion because
it was passed down to other macros before it was prefixed.
musl libc defines lfs64 names as macros (e.g. fstat64 as fstat)
so SYS_FUNC(fstat64) was expanded to sys_fstat.
This change adds the prefix before the name is passed to other macros,
i.e. the argument of SYS_FUNC_NAME is already prefixed with sys_.
* defs.h (SYS_FUNC): Add sys_ prefix to SYS_FUNC_NAME's argument.
(SYS_FUNC_NAME): Do not add sys_ prefix to MPERS_FUNC_NAME's argument.
* linux/ia64/syscallent.h (SYS_FUNC_NAME): Do not add sys_ prefix
to MPERS_FUNC_NAME's argument.
* syscall.c (SEN_NAME): Remove.
(SEN): Replace SEN_NAME call with its definition. Add sys_ prefix
to SYS_FUNC_NAME's argument.

Cleanup print_pc
Apparently, there are only two types of instruction pointer printers
depending on the architecture: those that print a register that was
fetched earlier, and those that fetch a register themselves using upeek.
With this change, architectures of the first type have ARCH_PC_REG
defined in their arch_regs.c file, architectures of the first type
have ARCH_PC_PEEK_ADDR defined there, and the common code in syscall.c
uses these macros to print the instruction pointer.

Add mpers support
Add a subsystem for semi-automatical definition of how parsers should
work with personality-dependent (mpers) types of tracee's data. Create
auxiliary libraries containing mpers syscall parsers and printer
functions, one library for each possible nonnative target personality.
Currently some parsers do not handle differences in definitions of data
types between personalities, namely LP64 and ILP32. When
this is the case, long integers, pointers, and all compound
types containing long and pointer members may be printed incorrectly,
because of differences in sizes, offsets and alignments.
Since in most cases these are the only differences in desired behaviour
of parsers and printers for different personalities, a correct way
would be to compile one source code into multiple parsers, differing
only in definitions of mpers types.
To get a definition of a given type for nonnative personality
a very basic .c file containing a declaration of a variable of this type
is being compiled for this personality (using -m32 or -mx32 compiler
flag). Information about the type is then being extracted from
this binary's DWARF debug info with an awk script and put
into a corresponding header file. Resulting headers are being used to
compile mpers variations of syscall parsers and printer functions.
In addition to syscall parsers, there can occur a need to create mpers
printing functions, which then can be called from many places
in the code (for example, printsiginfo_at). Such functions (printers)
are marked in a special manner.
For each possible nonnative target personality a library is being
created, containing mpers variations of syscall parsers and printers.
Only syscall parsers from files marked in a special manner and specially
marked functions from such files are being recompiled and included
in these libraries.
generate_mpers_am.sh is called by bootstrap to find the files
from strace_SOURCES which include MPERS_DEFS. During compilation,
these files are being inspected for inclusions of DEF_MPERS_TYPE,
and nonnative variations of each included type are being generated
by an awk script.
Mpers parser names are being modified during inclusions of syscallent
headers for nonnative personalities. Pointers to printers are
being stored in structs struct_printers, and a master
pointer printers is being updated on every set_personality.

Implement RVAL_DECODED flag
Implement a method for "on entering" parsers to return
"done with decoding" information to their callers.
If a syscall parser called from trace_syscall_entering returns a value
with RVAL_DECODED bit set, record this value in tcp->sys_func_rval
and use it in trace_syscall_exiting instead of calling the parser on
exiting syscall.
If an ioctl parser returned RVAL_DECODED, this would tell
SYS_FUNC(ioctl) that the decoding is finished but fallback printing of
the ioctl command argument is needed, while e.g. RVAL_DONE+1 would mean
that the decoding is finished and no fallback decoding is needed.
* defs.h (struct tcb): Add sys_func_rval.
(RVAL_DECODED): New macro.
* syscall.c (trace_syscall_entering): Initialize tcp->sys_func_rval
along with setting TCB_INSYSCALL flag.
(trace_syscall_exiting): Use tcp->sys_func_rval instead of calling
tcp->s_ent->sys_func when the former has RVAL_DECODED flag set.
Reset tcp->sys_func_rval along with clearing TCB_INSYSCALL flag.
* ioctl.c (sys_ioctl): Set RVAL_DECODED flag on exiting.
Print ioctl argument iff RVAL_DECODED is set and fallback decoding
is requested.

Show the syscall name in "resuming interrupted call" message
When signal is received, or if we have attached to a process,
current syscall (if process is in one) gets restarted.
Some syscalls are restarted via "restart_syscall()" mechanism.
On such sycalls, we don't show _which_ syscall gets restarted.
IOW: users want to see "resuming interrupted nanosleep"
instead of "resuming interrupted call" when they attach to "sleep 999".
Kernel does expose this information. The only thing we need is
to fetch syscall# on attach, and save it.
This patch does this. It adds tcp->s_prev_ent, which is
a pointer to struct_sysent of the previous syscall of this tracee.
It can be NULL.
sys_restart_syscall() is made to use it when the message is generated.
To similarly handle restart_syscall() *after signals*, not just
on attach, on each syscall exit patch saves exited syscall's data
in the same member (tcp->s_prev_ent).
Example:
$ sleep 3 & strace -p $!
Process 8728 attached
restart_syscall(<... resuming interrupted nanosleep ...>) = 0
_exit(0) = ?
+++ exited with 0 +++

As get_regs() is now guaranteed to fetch registers when either

ioctl: take all 32 bits of ioctl commands into account
Historically, only 16 bits (8-bit number and 8-bit type) of 32-bit ioctl
commands were used for decoding, which was the source for numerous
annoying collisions like this:
ioctl(0, SNDCTL_TMR_TIMEBASE or SNDRV_TIMER_IOCTL_NEXT_DEVICE or TCGETS, {B38400 opost isig icanon echo ...}) = 0
ioctl(0, MGSL_IOCGPARAMS or MMTIMER_GETRES or MTIOCTOP or SNDCTL_MIDI_MPUMODE, 0x7fffd47f7338) = -1 ENOTTY (Inappropriate ioctl for device)
The solution is to use all 32 bits for decoding, not just "number" and
"type", but also "size" and "direction".
As some architectures override defaults that come from asm-generic/ and
provide alternative definitions for some ioctl commands, we support
per-architecture ioctl definitions and merge them with common
definitions at build time. During the merge, we used to keep both
generic and architecture-specific definitions, now architecture-specific
definitions have precedence over generic ones -- ioctlsort omits
definitions from asm-generic/ for those ioctl names that have different
definitions in asm/.
Additional bits of "direction" are architecture specific -- the number
of bits and their values differ between architectures. To reduce
architecture differences in the source code, we keep "direction" in
symbolic form and compile it in ioctlsort.
Additional bits of "size" are also architecture specific -- not only the
number of bits differ between architectures, but sizes of many types
depend on sizeof(long). To reduce architecture differences in the
source code, we keep 32-bit and 64-bit versions of common ioctl
definitions, and use the appropriate version for each architecture and
personality.
To implement this, the tools for generating ioctl definitions from
kernel headers have been rewritten, and the source format of ioctl
definitions has been extended. The final ioctlent*.h files that are
included by syscall.c are now generated from source ioctls_inc*.h and
ioctls_arch*.h files at build time with ioctlsort.

unwind: move stacktrace capturing and mmap cache invalidating to trace_syscall_entering
Instead of handling stacktrace capturing and mmap cache invalidating in
sys_* functions, handle them uniformly in trace_syscall_entering using
new flags introduced by previous two commits.
The patch is simpler than its older version(v3). The value of
hide_log_until_execve is just ignored. I found the value is nothing
to do with this patch. unwind_cache_invalidate is mentioned only
once in trace_syscall_exiting.
Both are suggested by Dmitry Levin.

unwind: introduce markers specifying the needs of special care in unwinding
Some system calls require capturing the stack trace before they are
processed in kernel. Typical one is execve. Some system calls require
invalidating mmap cache after they are processed in kernel.
In current implementation these requirements are handled directly by
appropriate syscall handlers. However, it is difficult to keep the
source code maintainable using this approach to cover all system calls
which have such requirements.
A more generic way to implement this is to flag all syscalls that
require special processing, and handle these flags right in
trace_syscall_entering instead of changing syscall handlers.
This patch just defines new flags: STACKTRACE_INVALIDATE_CACHE and
STACKTRACE_CAPTURE_ON_ENTER.
The names of macros are suggested by Dmitry Levin.

ARM: remove wrong NSIG = 32 define
ARM in fact has 64 signals (1..64), and NSIG should be 65
(as usual, rememebr that NSIG_libc == NSIG_kernel+1).
I carefully reviewed all usages of NSIG. In syscall.c,
the only usage is:
for (i = 0; i <= NSIG; i++)
if (strcasecmp(s, signame(i) + 3) == 0)...
which is safe even if NSIG is way too big - signame(i)
returns a well-formed string for any i.
In signal.c, memcpy(&sigset, &sc.sc_mask, NSIG / 8) is used by
IA64 and TILE code, so ARM change can't affect it. And final
usage is:
struct new_sigaction::unsigned long sa_mask[NSIG / sizeof(long)];
It will grow on ARM (and become correct in the process).
Its only use is
memcpy(&sigset, &sa.sa_mask, NSIG / 8);
printsigmask(&sigset, 1);
which used to copy garbage in high bits, now it will copy actual data.

s390[x]: get rid of syscall_mode, delete code which never triggers
Before this change, the logic was as follows:
syscall entry:
get_scno:
syscall_mode = GPR2
scno = syscall_mode unless syscall_mode == -ENOSYS
(if -ENOSYS, scn is retrieved by decoding current insn)
fixup:
gpr2 = GPR2
syscall_mode = scno unless syscall_mode == -ENOSYS
if (gpr2 != syscall_mode) stray_entry
syscall exit:
get_res:
gpr2 = GRP2
fixup:
syscall_mode = scno unless syscall_mode == -ENOSYS
if (WAITEXECVE && gpr2 in (-ENOSYS, scno)) gpr2 = 0;
get_error:
gpr2 is retval
Entry fixup's if() can never trigger:
regardless whether GPR2 is -ENOSYS or not, syscall_mode is always
equal to GRP2 value there. So it can be removed.
On sysexit path, syscall mode is never used.
Therefore, syscall_mode variable is deleted. grp2 is read from
GPR2 register in get_scno, redundant read in entry fixup is removed.
As a result, entry fixup's s390 code block vanishes completely.
gpr2 variable is renamed s390_gpr2 to match the convention used
by other arches.

Add support for Imagination Technologies Meta
Add support for Imagination Technologies Meta architecture (the
architecture/ABI is usually referred to as metag in code). The Meta
Linux kernel port is in the process of being upstreamed for v3.9 so it
uses generic system call numbers.
sys_lookup_dcookie writes a filename to buffer argument, so I've set
TF flag.
nfsservctl appears to be set to sys_ni_syscall in asm-generic/unistd.h
so I've left it blank.
truncate64/ftruncate64/pread64/pwrite64/readahead have unaligned 64bit
args which are packed tightly on metag, so less arguments on metag.
fchdir/llseek takes a file descriptor so s/TF/TD/
sync_file_range has 2 64bit args so uses 6 args, so s/4/6/
timerfd_create/msgget/msgctl/msgrcv/semget/segtimedop/semop/shmget/
shmctl/shmat/shmdt/recvmsg/migrate_pages have different number of args.
oldgetrlimit is just getrlimit for metag.
add TM flag to various memory syscalls.
metag doesn't directly use sys_mmap_pgoff for mmap2.
prlimit64/process_vm_readv/process_vm_writev take a pid so add TP flag.

Eliminate MAX_QUALS, make qualifier array dynamic
MAX_QUALS was 2048, even though most arches used less than 500 entries
in it. MAX_QUALS had to be maintained by hand to be higher than syscall
count. It also limited the highest possible fd to track.
This change makes qual_flagsN[] arrays start sized to the required minimum
(number of syscalls) and grow dynamically if user requested
-e read=BIGNUM. As a precaution, BIGNUM should be < 2^15, but this limit
can be raised with no cost for normal strace invocations.
qual_flags is now a define to qual_vec[current_personality].
As a bonus, this patch aliases sysent, errnoent, signalent, ioctlent
names in one-personality arches to their corresponding <foo>0 arrays,
removing one indirection level.

Eliminate many SCNO_IS_VALID checks
By adding tcp->s_ent pointer tot syscall table entry,
we can replace sysent[tcp->scno] references by tcp->s_ent.
More importantly, we may ensure that tcp->s_ent is always valid,
regardless of tcp->scno value. This allows us to drop
SCNO_IS_VALID(tcp->scno) checks before we access syscall
table entry.
We can optimize (qual_flags[tcp->scno] & QUAL_foo) checks
with a similar technique.

ARM: make it one-personality arch
ARM in fact _is_ one personality.
We had two personalities for it because it has a handful of
syscalls with huge scnos (0x000f00xx).
Extending syscall table to have [0x000f0005] index is of course
not a good idea.
Someone decided to handle that by having a separate personality
just for these syscalls.
But multi-personality arch does a bit more work in other parts.
This patch is another alternative: "move" 0x000f00nn syscalls
down to the entries just above last ordinary syscall,
by manipulating scno if it falls into the 0x000f00xx range.
In order to not worsen genuine undefined scnos' printing,
the code remaps scno back to actual value before printing
"syscall_NNN" string.

Zero-extension is slightly more common that sign-extension:
all pointers are zero-extended, and some other params are unsigned.

_32-bit ints_ even by kernel, so just unconditionally casting
such tcp->u_arg[N] to int works.

ptrace(PTRACE_GETREGS, 22331, 0, 0x8087f00) = 0
ptrace(PTRACE_PEEKUSER, 22331, 4*EIP, [0x80dd7b7]) = 0

write(3, "[080dd7b7] ioctl(0, SNDCTL_TMR_T"..., 82) = 82

Restore tcb::u_lrval; fix lseek on MIPS-n32
Linux kernel v3.4 adds x32 support. Both x32 and n32 use 64bit offset
for lseek parameter and return value. We need u_lrval to handle it
properly. Also we shouldn't check HAVE_LONG_LONG_OFF_T for n32 lseek.
This patch fixes it properly and prepares lseek for x32.

Replace reprinting decision logic
After this change, we no longer need to decide when we need
to set TCB_REPRINT, and when we don't: it's never needed :)
Well, almost. That pesky pid-changing execve needs special treatment.

While at it, fix a case of mishandled -C.

Make ERESTARTxyz messages more descriptive
There is widespread confusion about exact meaning
of ERESTARTxyz codes. Before this change, we were showing
all four of them the same: as "(To be restarted)".
This change prints better explanations for these codes,
and contains verbose comments which explain *why* we display
codes that way - or else someone confused
is bound to come later and mangle them again.
New messages are:
ERESTARTSYS (To be restarted if SA_RESTART is set)
ERESTARTNOINTR (To be restarted)
ERESTARTNOHAND (Interrupted by signal)
ERESTART_RESTARTBLOCK (Interrupted by signal)
* syscall.c (trace_syscall_exiting): Make ERESTARTxyz messages
more descriptive.

Display mask on enter to sigreturn, not on exit
sys_sigreturn() performs ugly manipulations in order to show
signal mask which is restored by this syscall: on syscall entry,
fetches it from the stack, saves it in tcp->u_arg[]
(where it used to overflow this array - fixed sometime ago),
then retrieves the mask and displays it on syscall exit.
Apparently, the motivation is to make it slightly more obvious
to user that signal mask is restored only when this syscall returns.
IMO, this hardly justifies the necessary hacks. It is much easier
to display the mask at the point when we fetch it - on syscall entry.
While at it, I made it so that we do display returned value/errno.
I see no point in hiding it and showing uninformative "= ?" instead.
Example of pause() being interrupted by ALRM which has installed handler
which re-arms ALRM:
Before the patch:
rt_sigsuspend([INT]) = ? ERESTARTNOHAND (To be restarted)
--- {si_signo=SIGALRM, si_code=SI_KERNEL} (Alarm clock) ---
alarm(1) = 0
sigreturn() = ? (mask now [INT])
After:
rt_sigsuspend([INT]) = ? ERESTARTNOHAND (To be restarted)
--- {si_signo=SIGALRM, si_code=SI_KERNEL} (Alarm clock) ---
alarm(1) = 0
sigreturn() (mask [INT]) = -1 EINTR (Interrupted system call)
* defs.h: Declare struct pt_regs i386_regs and struct pt_regs x86_64_regs.
* syscall.c: Remove "static" keywork from these structures' definitions.
* signal.c (sys_sigreturn): Display mask on enter, not on exit.

get_scno is an unholy mess, make it less horrible
Currently, get_scno does *much* more than "get syscall no".
It checks for post-execve SIGTRAP. It checks for changes
in personality. It retrieves params on entry and registers on exit.
Worse still, it is different in different architectures: for example,
for AVR32 regs are fetched in get_scno(), while for e.g. I386
it is done in syscall_enter().
Another problem is that get_scno() is called on both syscall entry and
syscall exit, which is stupid: we don't need to know scno on syscall
exit, it is already known from last syscall entry and stored in
tcp->scno! In essence, get_scno() does two completely different things
on syscall entry and on exit, they are just mixed into one bottle, like
shampoo and conditioner.
The following patches will try to improve this situation.
This change duplicates get_scno into identical get_scno_on_sysenter,
get_scno_on_sysexit functions. Call them in syscall enter and syscall
exit, correspondingly.
* defs.h: Rename get_scno to get_scno_on_sysenter; declare it only
if USE_PROCFS.
* strace.c (proc_open): Call get_scno_on_sysenter instead of get_scno.
* syscall.c (get_scno): Split into two (so far identical) functions
get_scno_on_sysenter and get_scno_on_sysexit.
(trace_syscall_entering): Call get_scno_on_sysenter instead of get_scno.
(trace_syscall_exiting): Call get_scno_on_sysexit instead of get_scno.

Small optimization in signal and ioctl tables
Trivial shuffling of data tables puts them all in one file,
allowing gcc to see their sizes and eliminate variables
which store these sizes.
Surprisingly, in C mode gcc does not optimize out static const int
variables. Help it by using enums instead.

signalent{0,1,2}, nsignals{0,1,2}.

or enums if suitable.

Do not detach when we think tracee is going to die.
Current code plays some ungodly tricks, trying to not detach
thread group leader until all threads exit.
Also, it detaches from a tracee when signal delivery is detected
which will cause tracee to exit.
This operation is racy (not to mention the determination
whether signal is set to SIG_DFL is a horrible hack):
after we determined that this signal is indeed fatal
but before we detach and let process die,
*other thread* may set a handler to this signal, and
we will leak the process, falsely displaying it as killed!
I need to look in the past to figure out why we even do it.
First guess is that it's a workaround for old kernel bugs:
kernel used to deliver exit notifications to the tracer,
not to real parent. These workarounds are ancient
(internal_exit is from 1995).
The patch deletes the hacks. We no longer need tcp->nclone_threads,
TCB_EXITING and TCB_GROUP_EXITING. We also lose a few rather
ugly functions.
I also added a new message: "+++ exited with EXITCODE +++"
which shows exact moment strace got exit notification.
It is analogous to existing "+++ killed by SIG +++" message.
* defs.h: Delete struct tcb::nclone_threads field,
TCB_EXITING and TCB_GROUP_EXITING constants,
declarations of sigishandled() and internal_exit().
* process.c (internal_exit): Delete this function.
(handle_new_child): Don't ++tcp->nclone_threads.
* signal.c (parse_sigset_t): Delete this function.
(sigishandled): Delete this function.
* strace.c (startup_attach): Don't tcbtab[tcbi]->nclone_threads++.
(droptcb): Don't delay dropping if tcp->nclone_threads > 0,
don't drop parent if its nclone_threads reached 0:
just drop (only) this tcb unconditionally.
(detach): don't drop parent.
(handle_group_exit): Delete this function.
(handle_ptrace_event): Instead of handle_group_exit, just drop tcb;
do not panic if we see WIFEXITED from an attached pid;
print "+++ exited with EXITCODE +++" for every WIFEXITED pid.
* syscall.c (internal_syscall): Do not treat sys_exit specially -
don't call internal_exit on it.

Deindent syscall_enter by removing unnecessary braces. No code changes.
syscall_enter has many long (>80 columns) lines.
It is aggravated by the fact that it has a lot of {} blocks
which are not necessary (the code is the same without them).
This patch removes {}s and deindents affected lines.
While at it, it indents ifdefs so that nesting is easier to track,
and adds a few spaces in the expressions, such as
"tcp->u_nargs*sizeof..." -> "tcp->u_nargs * sizeof...".
There is no actual changes to the code here.

Do not suspend waitpid.
strace used to suspend waitpid until there is a child
for waitpid'ing process to collect status from.
Apparently, it was done because in some very old kernels
(circa 2002 or even earlier) there were ptrace bugs which
were making waitpid in real parent to not see children.
This kernel bug is fixed long ago. This change removes the workaround.
test/wait_must_be_interruptible.c is a test program which
illustrates why without this change strace changes
programs's behavior.

Replace many more bare ptrace calls with calls to wrappers
which do proper error-checking and set tcp->ptrace_errno.
In some cases, missing error checking is added.
Error handling for trace_syscall() failures and other cases
where tcp->ptrace_errno is nonzero is cleaned up a bit
and made more verbose if we see error other than ESRC.
Some comments are added or expanded.
* defs.h: Declare ptrace_cmds[]. Modify do_ptrace
declaration (last parameter is long, not void *).
* process.c: Make ptrace_cmds[] non-static.
(change_syscall): Use do_ptrace() instead of bare ptrace().
* signal.c: Use do_ptrace() instead of bare ptrace().
* strace.c: Update trace_syscall() failure handling.
* syscall.c: Use do_ptrace() instead of bare ptrace().
* util.c: Use do_ptrace() instead of bare ptrace().
Update do_ptrace() wrapper.
(str_PTRACE_xxx): New function - helper returning "PTRACE_xxx".
(do_ptrace_peekdata): New function - wrapper for PTRACE_PEEKDATA
(do_ptrace5): New function - wrapper for 5-argument ptrace calls.

Output format fixes, improving the situation after recent
change which added better handling of processes suddenly
disappearing. Now we often do not finish last line
before exiting in those cases.
The only change affecting something other than output
is change in umovestr where we were calling
abort() on ptrace error.
* strace.c (trace): If trace_syscall() failed with ESRCH,
finish current output line with " <unfinished ...>".
(mp_ioctl): While we are at it, fix gross style mismatch
in this function definition. No code chages.
* syscall.c (trace_syscall): If decode fails on syscall exit,
finish current output line with "= ? <unavailable>".
* util.c (umoven): Do not complain if error is ESRCH.

This patch does not change any logic.
It merely passes tcp pointer to upeek instead of pid.
This is needed if one wants to check or change
some tcp fields.
I have patches which require this. I can imagine someone else
eventually needing to look at tcp for completely orthogonal reasons.
