* As it turned out, "if (interrupted) break;" is needed in both loops,Denys Vlasenko2009-03-201-0/+2
| | | | | | | in "collect tasks" loop and in enclosing "collect/process" loop. Before this patch, "strace cat" + "killall -INT strace" wasn't making strace stop and exit. This patch restores 4.5.18 behavior in this regard.
* Remove "better attach to SIGSTOP", it is not correct...Denys Vlasenko2009-03-172-25/+9
| | | | (^C fix remains).
* * strace.c (startup_attach): Take care to correctly attachDenys Vlasenko2009-03-172-13/+33
| | | | | | to stopped processes by resending SIGSTOP. (collect_stopped_tcbs): Check for ^C here, not in trace(). (trace): Remove check for ^C.
* Decode fcntl's F_{GET,SET}LEASE, F_NOTIFY, and F_DUPFD_CLOEXEC.Denys Vlasenko2009-03-105-55/+147
| | | | | | | | | | | | | | | | | By Mike Frysinger (vapier AT gentoo.org) * desc.c: Add F_SETLEASE, F_GETLEASE, F_NOTIFY, F_DUPFD_CLOEXEC to fcntlcmds[]. Create notifyflags[] array. (sys_fcntl): Handle new flags. Optimize printing of open modes. * defs.h: Declare sprint_open_modes(), remove unused parameter in tprint_open_modes(). * desc.c (sprint_open_modes): Move fuction definition from here... * file.c (sprint_open_modes): To here. (tprint_open_modes): Use sprint_open_modes(), it already generates needed string. * ipc.c: Remove unused parameter from calls to tprint_open_modes().

* By Hans-Christian Egtvedt (hans-christian.egtvedt AT atmel.com):Denys Vlasenko2009-02-2513-124/+178
| | | | | | | strace.c: suppress "warning: unused static" message by adding #ifdef's around a variable .gitignore: trivial test/*.c: cleanup (suppress warnings, much better style).
* Replace many more bare ptrace calls with calls to wrappersDenys Vlasenko2009-02-247-298/+287
| | | | | | | | | | | | | | | | | | | | | 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.
* * process.c: Indent preprocessor directives so that nestingDenys Vlasenko2009-02-242-179/+176
| | | | can be figured out. Add PTRACE_SET_SYSCALL to ptrace_cmds[].

| | | | | | | | | | Removing redundant errnoent.h files. * Makefile.am: Remove references 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. * linux/s390/errnoent.h: Ditto. * linux/s390x/errnoent.h: Ditto. * linux/sh/errnoent.h: Ditto.

* Cleanup after tcb table expansion simplification.Denys Vlasenko2009-02-105-45/+35
| | | | | | | | | | 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. * strace.c (startup_attach): Remove usage of TCB_FOLLOWFORK. * syscall.c: Indent preprocessor directives.
* * defs.h: Correct the comment about TCB_SUSPENDED.Denys Vlasenko2009-02-094-244/+259
| | | | | | | | * 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.
* * strace.c (newoutf): Prevent -o FILENAME overflowing the stack.Denys Vlasenko2009-01-292-37/+44
| | | | | | | | (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.
* * process.c (internal_clone): Check and complain if pid valueDenys Vlasenko2009-01-283-23/+48
| | | | | | | | looks insane. * strace.c (alloc_tcb): Clear *all* fields in reused tcb. (main): Query and remember uname() info on startup. (handle_stopped_tcbs): Do not use PTRACE_SETOPTIONS on Linux < 2.6.29. (printleader): Correct printing of "<unavailable>" markers.
* * strace.c (collect_stopped_tcbs): Guard against the case whenDenys Vlasenko2009-01-272-5/+63
| | | | | waitpid() reports the same task multiple times. Run tested.
* * process.c (printwaitn): Add comment about wait4() pid expansion.Denys Vlasenko2009-01-264-16/+26
| | | | | | | Use #ifdef ALPHA instead of LINUX_64BIT, it was misleading (by implying "any 64-bit platform"). * defs.h: Remove now-unused LINUX_64BIT define. * resource.c (sys_osf_getrusage): Fix indentation.
* fix fallout from recent tcb table expansion error handling changeDenys Vlasenko2009-01-262-2/+10

* By Michal Nowak <mnowak@redhat.com>:Denys Vlasenko2009-01-232-3/+8
| | | | | | * mem.c (print_ldt_entry): Fix warning: Format '%#08lx' expects type 'long unsigned int', but argument 2 was type 'unsigned int'.
* * strace.c (collect_stopped_tcbs): Do not return NULL when ECHILDDenys Vlasenko2009-01-212-12/+16
| | | | | is detected, return collected list instead. Fixes symptom when the last "+++ killed by SIGxxx +++" is not printed.
* Two cleanups: tcb table expansion failure is not really a survivableDenys Vlasenko2009-01-175-80/+62
| | | | | | | | | | | | | | | | | | | | | 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.
* * defs.h: Update a comment. No code changes.Denys Vlasenko2009-01-174-8/+52
| | | | | | | | | * strace.c (handle_stopped_tcbs): Discard all execve stops and clear TCB_WAITEXECVE bit. * syscall.c (get_scno): Add the code to not mistakenly treat ptrace stop as execve stop (execve stops can be blocked by traced program). Fixes RH#477775 "strace hangs if the target process blocks SIGTRAP".
* * process.c: Add a comment. No code changes.Denys Vlasenko2009-01-173-17/+40
| | | | | | | | | | | * strace.c (collect_stopped_tcbs): Stop reversing list of stopped tcp's. I'm not totally convinced it is crucial, but this is surely fits the concept of "least surprise". Do not collect TCB_SUSPENDED tcp's (this is closer to how it was before). (handle_stopped_tcbs): Remove the code to reject TCB_SUSPENDED tcp's, it's done earlier now. In an unobvious way, this was causing SIGSTOPs from freshly attached children to be misinterpreted.
* * linux/bfin/syscallent.h: sys_futex has 6 parameters, not 5.Denys Vlasenko2009-01-142-1/+5
|
* Fixes for ptrace() argument parsing.Denys Vlasenko2009-01-139-19/+109
| | | | | | | | | | | | | | * process.c: Add parsing of PTRACE_SETOPTIONS, PTRACE_GETEVENTMSG, PTRACE_GETSIGINFO, PTRACE_SETSIGINFO. * strace.c (handle_stopped_tcbs): Make PTRACE_SETOPTIONS define check more robust. * 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.
