* linux/powerpc/errnoent.h: Remove, we can use common errnoent.h now.
2009-02-20 Denys Vlasenko <dvlasenk@redhat.com>
Patch by Mike Frysinger (vapier AT gentoo.org).
Removing redundant errnoent.h files.
* Makefile.am: Remove reference to linux/ia64/errnoent.h,
linux/s390/errnoent.h, linux/s390x/errnoent.h and linux/sh/errnoent.h.
* linux/ia64/errnoent.h: Remove, this arch uses common errnoent.h.

2009-02-10 Roland McGrath <roland@redhat.com>

* signal.c [LINUX] [M68K] (struct sigcontext): Don't define it if
[HAVE_STRUCT_SIGCONTEXT].
From Muttley Meen <muttley.meen@gmail.com>.
2009-02-09 Denys Vlasenko <dvlasenk@redhat.com>
* defs.h: Correct the comment about TCB_SUSPENDED.
* strace.c: Fix misplaced #endif.
* util.c: Indent preprocessor directives, mark code parts
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.
2009-01-29 Denys Vlasenko <dvlasenk@redhat.com>
* strace.c (newoutf): Prevent -o FILENAME overflowing the stack.
(startup_attach): Fix wrong pid in "Process <PID> attached".
(handle_group_exit): Do not consider exit to be spurious if
tcb has TCB_STARTUP bit set - we can attach to the task
right before its death, it can legitimately happen.
(handle_stopped_tcbs): Ditto.
2009-01-26 Denys Vlasenko <dvlasenk@redhat.com>
* process.c (printwaitn): Add comment about wait4() pid expansion.
Use #ifdef ALPHA instead of LINUX_64BIT, it was misleading
(by implying "any 64-bit platform").
* defs.h: Remove now-unused LINUX_64BIT define.

2009-01-26 Denys Vlasenko <dvlasenk@redhat.com>

2009-01-23 Michal Nowak <mnowak@redhat.com>
* syscall.c (get_scno): Fix warnings about unused variable 'pid'.
2009-01-23 Michal Nowak <mnowak@redhat.com>
* mem.c (print_ldt_entry): Fix warning:
Format '%#08lx' expects type 'long unsigned int', but
argument 2 was type 'unsigned int'.
2009-01-17 Denys Vlasenko <dvlasenk@redhat.com>
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.
2009-01-14 Denys Vlasenko <dvlasenk@redhat.com>
* linux/bfin/syscallent.h: sys_futex has 6 parameters, not 5.
2009-01-13 Denys Vlasenko <dvlasenk@redhat.com>
Fixes for ptrace() argument parsing.
* process.c: Add parsing of PTRACE_SETOPTIONS, PTRACE_GETEVENTMSG,
PTRACE_GETSIGINFO, PTRACE_SETSIGINFO.
* defs.h: Declare several "extern const struct xlat" arrays here.
* desc.c: Remove open_mode_flags[] and open_access_modes[]
extern declarations.
* net.c: Remove open_mode_flags[] extern declaration.
* sock.c: Remove addrfams[] extern declaration.
* util.c: Remove struct_user_offsets[] extern declaration.
* signal.c: Remove open_mode_flags[] extern declaration.
2009-01-06 Denys Vlasenko <dvlasenk@redhat.com>
Output format fixes, improving the situation after recent
change which added beeter 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.
2009-01-06 Denys Vlasenko <dvlasenk@redhat.com>
* desc.c (printflock): Fix display of fcntl(F_SETLK) on
non-native 32-bit architecture.
Fixes RH#471169 "format fcntl64() system calls for
32 bit application incorrect".
* desc.c: const'ify two static struct xlat vector[]'s,
convert all remaining old style C parameter declarations
in this file.
2008-11-13 Kirill A. Shutemov <kirill@shutemov.name>
* linux/arm/syscallent.h: Update syscalls.
Based on patch by Enrico Scholz.
* linux/arm/syscallent.h: Fix build on ARM EABI which does not
provide syscalls socketcall and ipc.
2009-01-01 Andreas Schwab <schwab@suse.de>
* net.c (sys_accept): Properly decode third argument as pointer to
int.
2008-12-30 Denys Vlasenko <dvlasenk@redhat.com>
Experimental support for -D option.
Unlike normal case, with -D *grandparent* process exec's,
becoming a traced process. Child exits (this prevents traced process
from having children it doesn't expect to have), and grandchild
attaches to grandparent similarly to strace -p PID.
This allows for more transparent interaction in cases
when process and its parent are communicating via signals,
wait() etc. Without -D, strace process gets lodged in between,
disrupting parent<->child link.
* strace.c: Add global flag variable daemonized_tracer for -D option.
(startup_attach): If -D, fork and block parent in pause().
In this case we are already a child, we in fact created a grandchild.
After attaching to grandparent, grandchild SIGKILLs parent.
(startup_child): If -D, parent blocks in wait(), then
execs the program to strace. Normally (w/o -D), it is child
who execs the program.
(main): Detect -D option, call startup_attach() if it is given.
2008-12-30 Kirill A. Shutemov <kirill@shutemov.name>
Fix some warnings on ARM build.
* defs.h: include <sys/ptrace.h> on arm too.
* syscall.c: EABI arm does not need decode_subcall(),
ifdef it out.
2008-12-29 Nick Black <dankamongmen@acm.org>
* linux/syscallent.h: Mark sendfile(2) as network syscall.
* linux/*/syscallent.h: Same, for all architectures.
2008-12-17 Denys Vlasenko <dvlasenk@redhat.com>
Make strace detect when traced process suddenly disappeared
(prime example is randomly arriving SIGKILL).
* defs.h (do_ptrace, ptrace_restart): Declare new functions
* process.c: Use ptrace_restart instead of bare ptrace.
This catches and records ESRCH errors.
Print "<unavailable>" if syscall decode or result can't be
determined because of an earlier error in ptrace()
* syscall.c (trace_syscall): Stop indiscriminately bailing out
on errors, print "syscall(????" or even "????(????" but continue.
* util.c (do_ptrace, ptrace_restart): Define new functions.
(upeek): use do_ptrace in order to catch and record ESRCH.
Do not print error message in this case.
Fixes RH#472053.
2008-12-17 Denys Vlasenko <dvlasenk@redhat.com>
* signal.c (sys_sigaction, sys_rt_sigaction): Fix typo
