38593e942ad4b16b2c3c43ea521167368771cbfb 26-Feb-2014 Dmitry V. Levin <ldv@altlinux.org> Rewrite signal mask decoding without sigset_t

The sigset_t provided by libc is not quite convenient.
In glibc, sigset_t is an array with space for 1024 bits, which is much
more than required: all architectures supported by Linux have only 64
signals except MIPS, which has 128.
In bionic libc, LP32 sigset_t is only 4 bytes long, which is less than
necessary.

With this change, signal mask is decoded without use of intermediate
sigset_t structure, which saves us some cpu cycles in case of glibc with
its inflated sigset_t, and enables build with libcs where sigset_t is
broken.

Old implementation used to check each signal number in the given signal
mask twice using sigismember().
New implementation is based on popcount and next_set_bit() so it's
noticeably faster.

In almost all cases, the parameter was 1 ("decode RT sigs too").
This change hardwires it to be 1.

The cases where it was 0 are, and why the change to "decode RT sigs too"
is fine:

IA64: 64-bit arch, all 64 signals fit in one word in any case.
S390[x]: sc.oldmask is a sigset_t on kernel side,
(sigset_t *)&sc.oldmask[0] does contain all 64 signals.
TILE: uc.uc_sigmask is a sigset_t on kernel side,
memcpy(&sigm, &uc.uc_sigmask, NSIG / 8) copies all 64 signals.

Replace print_sigset() with print_sigset_addr_len(),
which takes not only addr, but also len parameter.
This allows us to drop "do we need to print RT signals?" parameter,
and this fixes RT signals printing in many syscalls.

sys_epoll_pwait: print RT signals too, print sigmask size argument.

sys_sigprocmask: print_sigset -> print_sigset_addr_len(current_wordsize),
no change in functionality.

sys_sigpending: use print_sigset_addr_len(current_wordsize)
instead of open-coding it.

sys_rt_sigprocmask: use print_sigset_addr_len instead of open-coding it.
sys_rt_sigpending: ditto.
sys_rt_sigsuspend: ditto.

do_signalfd: print_sigset -> print_sigset_addr_len. This fixes
RT signals printing (wasn't showing them before).

sys_ppoll: ditto.

copy_sigset_len() is folded into its only user, print_sigset_addr_len(),
and copy_sigset() is gone.

While at it, checked kernel sources and noted where kernel enforces
sigset_size == NSIG / 8 (== sizeof(kernel_sigset_t)),
and where it allows word-sized sigset_size ([rt_]sigpending).

In practice, we always copy as many bytes as syscall param says
(8, or 16 on mips). However, malicious program can call sigaction
with wrong sigset size. Such syscall will result in EINVAL,
but we (strace) end up copying 128 bytes (sizeof(sigset_t)),
which copyes some garbage from stack after struct sigaction.

Now we always copy NSIG / 8 bytes (which is 8 bytes, or 16 on mips).

94e10354d888d1f09bc803616869802a13a576bf 18-Jul-2013 Denys Vlasenko <dvlasenk@redhat.com> 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.

tilegx support has been in the kernel since 3.0.
In addition, fix some issues with the tilepro support already
present in strace, primarily the decision to use the
<asm/unistd.h> numbering space for system calls.

* defs.h [TILE]: Include <asm/ptrace.h> and provide an extern
struct pt_regs tile_regs for efficiency. Provide compat 32-bit
personality via SUPPORTED_PERSONALITIES, PERSONALITY0_WORDSIZE,
PERSONALITY1_WORDSIZE, and DEFAULT_PERSONALITY.
* linux/tile/errnoent1.h: New file, includes linux/errnoent.h.
* linux/tile/ioctlent1.h: New file, includes linux/ioctlent.h.
* linux/tile/signalent1.h: New file, includes linux/signalent.h.
* linux/tile/syscallent.h: Update with new asm-generic syscalls.
The version previously committed was the from the first tile patch
to LKML, which subsequently was changed to use <asm-generic/unistd.h>.
* linux/tile/syscallent1.h: Copy from linux/tile/syscallent.h.
* mem.c (addtileflags) [TILE]: use %ld properly for a "long" variable.
* process.c [TILE]: Choose clone arguments correctly and properly
suppress all "struct user" related offsets in user_struct_offsets.
* signal.c [TILE]: Use tile_regs not upeek.
* syscall.c (update_personality) [TILE]: Print mode.
(PT_FLAGS_COMPAT) [TILE]: Provide if not in system headers.
(tile_regs) [TILE]: Define 'struct pt_regs' variable to hold state.
(get_regs) [TILE]: use PTRACE_GETREGS to set tile_regs rather than using upeek.
(get_scno) [TILE]: Set personality.
(get_syscall_args) [TILE]: Use tile_regs.
(get_syscall_result) [TILE]: Update tile_regs.
(get_error) [TILE]: Use tile_regs.
(printcall) [TILE]: Print pc.
(arg0_offset, arg1_offset, restore_arg0, restore_arg1) [TILE]:
Properly handle tile call semantics and support tilegx.

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
ptrace(PTRACE_SYSCALL, 22549, 0, SIG_0) = 0

Analogous improvement in sys_sigreturn() is also implemented.

* defs.h: Declare extern struct pt_regs regs for SPARC[64] and ARM.
Declare clear_regs(), get_regs() and get_regs_error flag variable.
* strace.c (trace): Call get_regs(pid) as soon as we know the tcb
and that it is stopped.
* syscall.c (get_regs): New function. Used to fetch registers early,
just after tracee has stopped.

osf_sigprocmask(SIG_SETMASK, [HUP INT]) = 0 (old mask [])
osf_sigprocmask(SIG_UNBLOCK, []) = 0x3 (old mask [HUP INT])

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.

b11322fd3c8d291061d69e40e28004b97b91b15d 10-Jan-2012 Denys Vlasenko <dvlasenk@redhat.com> 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)

39fca628019cbfa01835482ac8559e21fde7f03c 20-Aug-2011 Denys Vlasenko <dvlasenk@redhat.com> 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.

* defs.h: Stop exporting ioctlent{0,1,2}, nioctlents{0,1,2},
signalent{0,1,2}, nsignals{0,1,2}.
* ioctl.c: Remove definitions of ioctlent{,0,1,2} and nioctlents{,0,1,2}.
* signal.c: Remove definitions of signalent{,0,1,2} and nsignals{,0,1,2}.
* syscall.c: Move above definitions to this file. Make them static const
or enums if suitable.

d9560c108099394281012eb4bd7c46a46df6d31d 19-Aug-2011 Denys Vlasenko <dvlasenk@redhat.com> 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.

* defs.h: Reduce MAX_ARGS for X86_64 and I386 from 32 to 8
for FreeBSD and to 6 for everyone else. Add comment about current
state of needed MAX_ARGS.
* signal.c: Add comment about size of sigset_t.

19cdada5b499b978ffd9c3367b4ef34ad6f8bf2b 17-Aug-2011 Denys Vlasenko <dvlasenk@redhat.com> 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.

* signal.c (parse_sigset_t): Delete this function.

(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.

4dedd561d61562fe66f1a0b673ad33ac6a1e3c71 24-Feb-2009 Denys Vlasenko <dvlasenk@redhat.com> 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.

932fc7d4fc1a29e8b8bcea5685db3f6c2e212e36 16-Dec-2008 Denys Vlasenko <dvlasenk@redhat.com> 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.
