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.

unwind: implement automatic mmap cache invalidation
A mmap cache belonging to a tcb was updated when a system call which
changed the memory mapping was called. This implementation was assumed
the mapping was changed only by the tcb. However, this assumption is
incorrect if the target application is multi-threaded; more than two
tcbs can shared the same memory mapping and a tcb can modify it without
being noticed by the others.
This change introduces a global integer variable mmap_cache_generation,
and mmap_cache_generation field to struct tcb. The variable
is incremented each time a process enters a syscall that can modify its
memory mapping. Each tcb records the value of this variable at the
moment if building its mmap cache. Every mmap cache associated with
the given tcb can be validated by comparing its mmap_cache_generation
field with the variable mmap_cache_generation.
This implementation is inefficient. If strace attaches two processes
which don't share the memory mapping, rebuilding mmap cache of a tcb
triggered by another tcb's mmap system call is not necessary.

unwind: introduce queue_t for capturing stacktrace
This is the second step for splitting capturing from printing.
New `queue' field is added to tcb. Captured stacktrace is stored here.
The field is initialized/finalized at unwind_tcb_init/unwind_tcb_fin.
New API function unwind_capture_stacktrace is added. This function
captures the currest stack using stracktrace_walker and records it in
tcb. It's printing is delayed to the next call of
unwind_print_stacktrace.
unwind_print_stacktrace is extended. Now it checks queue field of
the given tcb at the start of function. If the function finds a
captured stack trace, the latter is printed using stracktrace_walker.
Currently unwind_capture_stacktrace invocations are added directly to
handlers of mmap, munmap, mprotect, and execve.
Here is the difference of output with/without patch:
(without patch)
execve("./test-fork", ["./test-fork"], [/* 56 vars */]) = 0
> /usr/lib64/ld-2.18.so(check_one_fd.part.0+0x82) [0x11f0]
(with patch)
execve("./test-fork", ["./test-fork"], [/* 54 vars */]) = 0
> /usr/lib64/libc-2.18.so(execve+0x7) [0xbcd27]
> /home/yamato/var/strace/strace(exec_or_die+0x10c) [0x26ac]

> /home/yamato/var/strace/strace(_start+0x29) [0x2799]
In older version output lines of captured elements were built when
printing. In this version they are built when capturing the stack.
As result, unneeded dynamic memory allocations are avoided.
Suggested by Luca Clementi.
In older version the combination of snprintf and realloc were used.
In this version they are replaced with asprintf.
Suggested by Dmitry Levin.

Time spent in system time is not useful where a syscall depends on some
non-CPU resource, eg. typically open() or stat() to a network drive.
This patch adds a new flag (-w) to produce a summary of the time

Fix {get,set}rlimit decoding with unreliable SIZEOF_RLIM_T
When strace is built with large file support definitions in CFLAGS (as
may be provided by buildroot) the C library headers may expose a 64-bit
rlim_t even though the struct rlimit fields used by the system call
interface are only 32-bit. The SIZEOF_RLIM_T will then be 8 which
results in bad decoding of the getrlimit and setrlimit syscalls.
This is fixed by replacing unreliable SIZEOF_RLIM_T based checks with
checks for current_wordsize.

Even with the -q flag specified, tracing output is still mixed
with messages about signals and process exit status, which is
often irrelevant. Allow the -q option to be repeated to force
the suppression of signals / exit status info too.

mips: fix build regression
The recent commit (2690fadc8b35190dddd29274a7405bac13adc469) shuffled
the mips headers around causing it to check the ABI defines before it
included the header which set those up. Now all mips builds fail with:

Open-code isprint(c) and isspace(c)
We don't call setlocale, thus we always use C locale.
But libc supports various other locales, and therefore
its ctype interface is general and at times inefficient.
For example, in glibc these macros result in function call,
whereas for e.g. isprint(c) just c >= ' ' && c <= 0x7e
suffices.
By open-coding ctype checks (we have only 4 of them)
we avoid function calls, we get smaller code:
text data bss dec hex filename
245127 680 5708 251515 3d67b strace_old
245019 676 5708 251403 3d60b strace
and we don't link in ctype tables (beneficial for static builds).

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.

* syscall.c (shuffle_scno): New function.
(undefined_scno_name): New function.

Optimize out PTRACE_PEEKUSER with -i
strace -i was fetching PC with a separate PEEKUSER
despite having GETREGS data:
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
ptrace(PTRACE_SYSCALL, 22331, 0, SIG_0) = 0
Now it does this:
ptrace(PTRACE_GETREGS, 22549, 0, 0x8087ea0) = 0
write(3, "[080dd7b7] ioctl(0, SNDCTL_TMR_T"..., 82) = 82

Report some ptrace failures; nuke tcp->ptrace_errno
Report some (not all) ptrace errors, namely,
errors on ptrace restart operations.
Before: 10533 sendto(-1, 0x804895e, 17, 0, NULL, 0 <unfinished ...>
After: 10533 sendto(-1, 0x804895e, 17, 0, NULL, 0 <ptrace(SYSCALL):No such process>
This tells user that strace failed to let sendto syscall
to be entered - process was dead at that point of time.
It is (marginally) better than to always say "<unfinished ...>"
While at it, patch removes tcp->ptrace_errno.
I added it many months ago, and it looks that after all
it is not needed for ptrace error detection: I failed to execute
a single existing code path which is accessible
through that variable only.

Pass addr=0 instead of 1 into restarting ptrace calls
While we are at it, fold do_ptrace into its lone caller.
We no longer set tcp->ptrace_errno = ESRCH on ESRC error in upeek.
Other code paths where ptrace fails wern't doing it, and the code which
checks tcp->ptrace_errno even assumes it is never set to ESRCH.

that it was a bit messy)
I ran sigkill_rain test and verified that unfinished syscalls are
still handled correctly.

Add experimental code to use PTRACE_SEIZE, disabled by default
All new code is predicated on "ifdef USE_SEIZE". If it is not defined,
behavior is not changed.
If USE_SEIZE is enabled and run-time check shows that PTRACE_SEIZE works, then:
- All attaching is done with PTRACE_SEIZE + PTRACE_INTERRUPT.
This means that we no longer generate (and possibly race with) SIGSTOP.
- PTRACE_EVENT_STOP will be generated if tracee is group-stopped.
When we detect it, we issue PTRACE_LISTEN instead of PTRACE_SYSCALL.
This leaves tracee stopped. This fixes the inability to SIGSTOP or ^Z
a straced process.
* defs.h: Add commented-out "define USE_SEIZE 1" and define PTRACE_SEIZE
and related constants.

Get rid of TCB_SIGTRAPPED
On attempts to block or set SIGTRAP handler,
for example, using sigaction syscall, we generate
an additional SIGSTOP.
This change gets rid of this SIGSTOP sending/ignoring.
It appears to work just fine.
It also works if I force strace to not use PTRACE_O_TRACESYSGOOD,
which means strace stops will be marked with SIGTRAP,
not (SIGTRAP | 0x80) - I wondered maybe that's when
this hack is needed.
So, why we even have TCB_SIGTRAPPED? No one knows. It predates
version control: this code was present in the initial commit,
in 1999. No adequate comments, either.
Moreover, TCB_SIGTRAPPED is not set in sys_rt_sigaction
and sys_sigprocmask syscalls - the ones which are most usually
used to implement signal blocking, it is only set in obsolete
sys_signal, sys_sigaction, sys_sigsetmask, and in some dead
non-Linux code.
I think whatever bug it was fixing is gone long ago -
at least as long as sys_rt_sigaction is used by glibc.
Again, since glibc (and uclibc) uses sys_rt_sigaction
and sys_sigprocmask, modified code paths are not used
by most programs anyway.
* defs.h: Remove definition of TCB_SIGTRAPPED.
* signal.c (sys_sigvec): Don't set TCB_SIGTRAPPED and don't send SIGSTOP.

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)

Do post-attach initialization earlier; fix "we ignore SIGSTOP on NOMMU" bug
We set ptrace options when we see post-attach SIGSTOP.
This is wrong: it's better to set them right away on the very first
stop (whichever it will be). It also will make adding SEIZE support easier,
since SEIZE has no post-attach SIGSTOP.
We do it by adding a new bit, TCB_IGNORE_ONE_SIGSTOP, and treating
TCB_STARTUP and TCB_IGNORE_ONE_SIGSTOP as two slightly different things.
* defs.h: Add a new flag bit, TCB_IGNORE_ONE_SIGSTOP.
* process.c (internal_fork): Set TCB_IGNORE_ONE_SIGSTOP on a newly added child.
* strace.c (startup_attach): Set TCB_IGNORE_ONE_SIGSTOP after attach.
Fix a case when "strace -p PID" found PID dead but sone other of its threads
still alive.
(startup_child): Set TCB_IGNORE_ONE_SIGSTOP after attach, _if needed_.
This fixes a bogus case where we can ignore a _real_ SIGSTOP on NOMMU.
(detach): Perform anti-SIGSTOP dance only if TCB_IGNORE_ONE_SIGSTOP is set,
not if TCB_STARTUP is set.
(trace): Set TCB_IGNORE_ONE_SIGSTOP after attach.

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

Set saner MAX_ARGS (6 or 8) for X86_64 and I386
I noticed that tcp->u_args[MAX_ARGS] array is way larger than
I'd expect: for all arches except HPPA it has 32 (!) elements.
I looked at the code and so far I spotted only one abuser of
this fact: sys_sigreturn. On several arches, it saves sigset_t
into tcp->u_args[1...N] on entry and prints it on exit, a-la
memcpy(&tcp->u_arg[1], &sc.oldmask[0], sizeof(sigset_t))
The problem here is that in glibc sigset_t is insanely large:
128 bytes, and using sizeof(sigset_t) in memcpy will overrun
&tcp->u_args[1] even with MAX_ARGS == 32:
On 32 bits, sizeof(tcp->u_args) == 32*4 == 128 bytes!
We may already have a bug there!
This commit changes the code to save NSIG / 8 bytes only.
NSIG can't ever be > 256, and in practice is <= 129,
thus NSIG / 8 is <= 16 bytes == 4 32-bit words,
and even MAX_ARGS == 5 should be enough for saving signal masks.

Remove tcp->parent and TCB_CLONE_THREAD.
tcp->parent is used for only two things:
(1) to send signal on detach via tgkill (need to know tgid).
Solution: use tkill, it needs only tid.
(2) to optimize out ptrace options setting for new tracees.
Not a big deal if we drop this optimization: "set options" op is fast,
doing it just one extra time once per each tracee is hardly measurable.
TCB_CLONE_THREAD is a misnomer. It used only to flag sibling we attached to
in startup_attach. This is used to prevent infinite recursive rescanning
of /proc/PID/task.
Despite the name, there is no guarantee it is set only on non-leader:
if one would run "strace -f -p THREAD_ID" and THREAD_ID is *not*
a thread leader, strace will happily attach to it and all siblings
and will think that THREAD_ID is the leader! Which is a bug, but
since we no longer detach when we think tracee is going to die,
this bug no longer matters, because we do not use the knowledge
about thread group leaders for anything. (We used it to delay
leader's exit).
IOW: after this patch strace has no need to know about threads, parents
and children, and so on. Therefore it does not track that information.
It treats all tracees as independent entities. Overall,
this simplifies code a lot.
* defs.h: Add TCB_ATTACH_DONE flag, remove TCB_CLONE_THREAD flag
and struct tcb::parent field.
* process.c (internal_fork): Don't set tcpchild->parent.
* strace.c (startup_attach): Use TCB_ATTACH_DONE flag instead of
TCB_CLONE_THREAD to avoid attach attempts on already-attached threads.
Unlike TCB_CLONE_THREAD, TCB_ATTACH_DONE bit is used only temporarily,
and only in this function. We clear it on every tcb before we return.
(detach): Use tkill instead of tgkill.
(trace): Set ptrace options on new tracees unconditionally,
not only when tcp->parent == NULL.

Remove TCB_SUSPENDED constant and related code.
Since we no longer suspend waitpid'ing tracees, we have only one case when
we suspend tracee: when we pick up a new tracee created by clone/fork/vfork.
Background: on some other OSes, attach to child is done this way:
get fork's result (pid), loop ptrace(PTRACE_ATTACH) until you hook up
new process/thread. This is ugly and not safe, but what matters for us
is that it doesn't require suspending. Suspending is required
on Linux only, because on Linux attach to child is done differently.
On Linux, we use two methods of catching new tracee:
adding CLONE_THREAD bit to syscall (if needed, we change
[v]fork into clone before that), or using ptrace options.
In both cases, it may be so that new tracee appears before one which
created it returns from syscall. In this case, current code
suspends new tracee until its creator returns. Only then
strace can determine who is its parent (it needs child's pid for this,
which is visible in parent's [v]fork/clone result).
This is inherently racy. For example, what if SIGKILL kills
creator after it succeeded creating child, but before it returns?
Looks like we will have child suspended forever.
But after previous commit, we DO NOT NEED parent<->child link for anything.
Therefore we do not need suspending too. Bingo!
This patch removes suspending code. Now new tracees will be continued
right away. Next patch will remove tcp->parent member.
* defs.h: Remove TCB_SUSPENDED constant
* process.c (handle_new_child): Delete this function.
(internal_fork): Do not call handle_new_child on syscall exit.
* strace.c (handle_ptrace_event): Delete this function.

of now impossible TCB_SUSPENDED condition.

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.

Fix regression introduced by "Properly handle real SIGTRAPs" change
Commit 3454e4b463e6c22c7ea8c5461ef5a077f4650a54
introduced a bug: sometimes, TRACECLONE/TRACE[V]FORK opts were not set.
The check (tcp->parent == NULL) in old code was meant to check
"if we are not a child created by auto-attach" - in this case,
options need to be set on the child; otherwise they are inherited
and do not need to be set.
I misunderstood the check and if tcp->parent is not NULL, I was
setting only ptrace_setoptions_for_all bits.
This change fixes the problem. Since the fixed logic makes it
unnecessary to keep two sets of options in separate variables,
I merge them back into one variable, ptrace_setoptions.

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 how PTRACE_SETOPTIONS support works
Currently test fork related options only. Fork a child that uses
PTRACE_TRACEME at startup and then does a fork so strace can test
how the PTRACE_SETOPTIONS support works before it handles any real
tracee. Since PTRACE_O_TRACECLONE/*FORK were introduced to kernel
at the same time, this test seems to be enough for these 3 options.
* defs.h [LINUX]: Define PTRACE_O_TRACECLONE et al macros here.
(ptrace_setoptions): New variable declaration.
* strace.c [LINUX] (test_ptrace_setoptions): New function, tests
whether kernel supports PTRACE_O_CLONE/*FORK, the result is stored
in the new variable ptrace_setoptions for later use.

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

Cleanup after tcb table expansion simplification.
There was code which was trying to continue tracing
even if table expansion fails. Now we treat it as fatal
failure, so this code is removed by this change.
* defs.h: Delete TCB_FOLLOWFORK constant.
* process.c: Delete fork_tcb() and all calls of it.

which can never be reached by compilation because of
the combination of #if directives. These are likely dead code,
I want to remove them later.

Two cleanups: tcb table expansion failure is not really a survivable
event, we do not have any viable way to continue. No wonder most
places where that is detected have FIXMEs.
It's way simpler to treat as fatal failure, and handle it inside
tcb table expansion finctions.
Second cleanup: tidy up haphazard locations of a few externs.
* defs.h: Change return type of expand_tcbtab() to void.
Declare change_syscall().
* process.c: Change all callsites of alloctcb(), alloc_tcb() and
fork_tcb(), removing now-redundant error checks.
(fork_tcb): Change return type to void - it can't fail now.
* strace.c: Move extern declarations out of function bodies.
Change all callsites of alloctcb(), alloc_tcb() and
fork_tcb(), removing now-redundant error checks.
(expand_tcbtab): Change return type to void - it can't fail now.
On failure to expand, print a message, clean up, and exit.
(alloc_tcb): On failure to expand, print a message, clean up, and exit.
* util.c (setbpt): Remove extern declaration from function body.

collect_stopped_tcbs() and handle_stopped_tcbs().
Now we collect *all* waitable tasks, then handle them all,
then repeat.
Fixes RH#478419 "Some threads stop when strace with -f option

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.
(umovestr): Do not complain and do not abort() if error is ESRCH.
* defs.h: Remove unused tcp parameter from printtrailer().
* process.c: Adjust printtrailer() calls accordingly.
* strace.c: Adjust printtrailer() calls accordingly.
* syscall.c: Adjust printtrailer() calls accordingly.

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.
