ChangeLog

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.

2009-01-17  Denys Vlasenko  <dvlasenk@redhat.com>

	* defs.h: Update a comment. No code changes.
	* 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".

2009-01-17  Denys Vlasenko  <dvlasenk@redhat.com>

	* process.c: Add a comment. No code changes.
	* 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.

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.
	* 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.

2009-01-09  Denys Vlasenko  <dvlasenk@redhat.com>

	* defs.h: Add new struct tcb fields: wait_status, next_need_service.
	make flags field wider (ints are easier to work with on many CPUs).
	* strace.c (trace): Split this function into two:
	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
	is executed on a multi-thread process"
	* test/many_looping_threads.c: example program which cna't be straced
	successfully without this fix.

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.

2009-01-02  Denys Vlasenko  <dvlasenk@redhat.com>

	* strace.c: Fix compile failure: on some systems PTRACE_O_xxx
	and PTRACE_EVENT_xxx constants are not defined because
	those system have old kernel headers.
	OTOH, if PT_SETOPTIONS is not defined too,
	I don't risk using ptrace options, the kernel is too old.
	I've seen problems on RHEL4 ia64 when I tried to.

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.

2008-12-29  Denys Vlasenko  <dvlasenk@redhat.com>

	* defs.h: Remove sigtrap80 field from struct tcb.
	* strace.c: Add ptrace_stop_sig static variable
	and use it in place of tcp->sigtrap80.
	Add ptrace_opts_set static flag variable.
	(trace): Set ptrace options once, not per-process.
	If unexpected SIGTRAP is later received,
	revert back to using SIGTRAP
	(assume old, broken kernel).

2008-12-22  Denys Vlasenko  <dvlasenk@redhat.com>

	Make strace correctly handle SIGTRAP produced by e.g.
	kill(2) and by trapping instruction.
	* defs.h: Add sigtrap80 field to struct tcb.
	* strace.c (alloc_tcb): Initialize it to SIGTRAP.
	(detach): Use tcp->sigtrap80 instead of SIGTRAP constant.
	(trace): Attempt to set PTRACE_O_TRACESYSGOOD and
	PTRACE_O_TRACEEXEC options on each newly attached process,
	distinquish between SIGTRAP and (SIGTRAP | 0x80) stops.
	Fixes RH#162774 "strace ignores int3 SIGTRAP".

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.

	* signal.c (sys_sigaction, sys_rt_sigaction): Fix typo

	(foobar): New dummy signal handler.
	(main): Install a dummy signal handler in the child before pausing
	to work around an SGI bug in PRSABORT.
	(proc_open): Send a interrupt to the child instead of aborting the
	syscall which doesn't work on Irix5.2.
	* svr4/dummy.h: Add new unfinished SGI syscalls
	(e.g. sys_sysmp, sys_sginap, etc.).  Handle some SGI syscalls like
	existing calls (e.g. sys_ksigaction like sys_sigaction).
	Printargs does the print thing for sys_sethostid.
	* svr4/syscall.h: Declare all new SGI syscalls.
	(SGI_KLUDGE): Define syscall table starting index to be 1 for SGI
	and add it to all subcall entry points.
	(SYS_pgrpsys_subcall, SYS_sigcall_subcall, SYS_context): Don't
	decode as subcalls on MIPS. Instead, use the normal syscalls.
	* svr4/syscallent.h [MIPS]: Lead syscall table with a dummy entry
	since SGI syscall numbers are off by one.
	[MIPS] (sys_pgrpsys): Rename to sys_setpgrp on SGI.
	[MIPS] (sys_xenix): Rename to sys_syssgi on SGI.
	[MIPS] (sys_sysmachine): Rename to sys_sysmips on SGI.
	[MIPS]: Conditionalize SVR4 extension into SGI and Solaris classes.
	* syscall.c (dumpio): Validate descriptor against MAX_QUALS.
	[HAVE_PR_SYSCALL] (syscall): Conditionalize SYS_vfork.
	[MIPS] (syscall): Add SGI section for decoding u_error and u_rval.
	Add workaround for broken SGI pr_sysarg on syscall entry.
	[SVR4] (syscall): Conditionalize subcall decoding for
	SYS_ptrpsys_subcall, SYS_sigcall_subcall and SYS_context_subcall.
	[SVR4] [MIPS] (getrval2): Handle SGI.
	* syscallent.sh: Dork the sed line to be choosier about SYS_ lines.
	* system.c [HAVE_SYSCONFIG_H]: Include sys/sysconfig.h.
	[MIPS] (syssgi_options, sys_syssgi): New for SGI.
