ChangeLog

2002-12-16  Roland McGrath  <roland@redhat.com>

	* signal.c (sprintsigmask): Increase static buffer size to account for
	worst possible case.  Reported by Daniel Jacobowitz <drow@false.org>.

	* process.c [LINUX] (wait4_options): Fix __WCLONE value.  Add
	__WNOTHREAD and __WALL.

	* strace.c (trace) [LINUX]: Only check errno if wait4 actually fails,
	so we don't repeat a wait and thus drop a status.  Fixes RH#62591.

2002-12-15  Roland McGrath  <roland@redhat.com>

	* process.c (setarg) [POWERPC]: Support it.

	* util.c [POWERPC] (LOOP): Fix value, now 0x48000000 (0: b 0b).
	Old value was bogus, not even a proper instruction.
	From Guy M. Streeter <streeter@redhat.com>.

	* strace.c (main) [! USE_PROCFS]: Always reset SIGCHLD to SIG_DFL.

	* configure.in: Don't check for putpmsg.
	* stream.c (sys_getpmsg, sys_putpmsg): Make these conditional on
	#ifdef SYS_*, rather than on HAVE_PUTPMSG.

	* aclocal.m4 (AC_STAT64): Include <linux/types.h> before <asm/stat.h>
	in test.  Test our own #ifdef LINUX rather than predefined `linux'.

	* linux/powerpc/syscallent.h: Use sys_llseek for _llseek.
	* linux/sparc/syscallent.h: Likewise.
	* linux/hppa/syscallent.h: Likewise.

	* syscall.c (syscall_enter) [LINUX && POWERPC]: Define PT_ORIG_R3 if
	not defined, since <asm/ptrace.h> defines it only #ifdef __KERNEL__.
	* process.c: Likewise.

	* desc.c (sys_osf_select): Add missing return type.

	* syscall.c (trace_syscall): Use strerror, not sys_errlist/sys_nerr.

	* linux/ia64/syscallent.h: Remove macros for sys_delete_module,
	sys_nanosleep, both already in linux/dummy.h.

	* syscall.c (get_scno): Move static `currpers' inside #ifdef X86_64.
	(trace_syscall): Fix return without value.

	* linux/syscallent.h: Update table with names of new syscalls
	io_setup, io_destroy, io_getvents, io_submit, io_cancel.
	* linux/ia64/syscallent.h: Likewise.
	* linux/powerpc/syscallent.h: Likewise.

	* signal.c [LINUX && I386]: Provide SA_RESTORER constant if not
	defined.  If the bit is set, print the sa_restorer field of sigaction.

	* mem.c: Add sys_{get,set}_thread_area.
	* linux/syscall.h: Declare them.
	* linux/syscallent.h: Update the table for these.
	* linux/dummy.h (sys_modify_ldt): Define only #ifndef I386.
	(sys_get_thread_area, sys_set_thread_area): New macros #ifndef I386.

	* configure.in: Check for linux/xattr.h and linux/futex.h headers.
	* linux/syscall.h: Add sys_* decls for new syscalls getpmsg, putpmsg,
	readahead, sendfile64, setxattr, fsetxattr, getxattr, fgetxattr, int
	listxattr, flistxattr, removexattr, fremovexattr, sched_setaffinity,
	sched_getaffinity, futex.
	* linux/syscallent.h: Update the table.
	* io.c: Add sys_sendfile64.
	* file.c: Add sys_readahead, sys_*xattr.
	* process.c: Add sys_futex, sys_*affinity.

	* linux/syscall.h (SYS_socket_subcall): Define to 256 on all machines.
	(SYS_ipc_subcall): Always SYS_socket_subcall + SYS_socket_nsubcalls.
	* linux/syscallent.h: Update the table for socket and ipc subcalls.

	* linux/ia64/Makefile.in (ioctldefs.h ioctls.h): Update for
	new ioctlent.h generation scheme.

	* linux/syscall.h (sys_clone2): Declare.
	[IA64] Define ia32 socket, ipc, and extra syscall numbers.

	[IA64]: Declare "ia32" variable.

  * net.c: fix display of sockaddr structures, sometimes too many "}",
    sometimes too few.  Fix suggested by Richard Kettlewell.

2001-08-19   Wichert Akkerman <wakkerma@debian.org>

  * signal.c: do not include asm/sigcontext.h on IA64 since it gets
    the struct from bits/sigcontext.h already which signal.h includes.

  * linux/ioctlent.sh: change regexps so we catch sound ioctls as well in

  * config.{guess,sub}: updated

2001-05-15  John Hughes <john@Calva.COM>

	* util.c (umovestr) [LINUX]: Handle Linux like SunOS4
	instead of SVR4.  That is, read a few bytes at a time
	to avoid overrunning the end of the stack.

Fri May 31 01:48:49 1996  J. Richard Sladkey  <jrs@world.std.com>

	* version.c: Version 3.1 is released.

Thu May 23 01:04:43 1996  J. Richard Sladkey  <jrs@world.std.com>

	* aclocal.m4 (AC_DECL_SYS_ERRLIST): Try looking in stdio.h
	as well since that's where glibc declares it.  Go figure.
	* signal.c (sys_sigreturn) [ALPHA]: Use sigcontext
	instead of sigcontext_struct since glibc v5+ apparently
	plays games with the native OS namespace.
	From David Mosberger-Tang <davidm@AZStarNet.com>.

Mon May 20 23:17:14 1996  J. Richard Sladkey  <jrs@world.std.com>

 	sys/filio.h and sys/stream.h and remove check for poll.
	* desc.c (decode_select, sys_select, sys_oldselect) [LINUX]:
 	Handle old and new styles of argument passing for select on Linux.
	* ioctl.c, stream.c: Conditionalize stream code on presence of
	sys/stream.h instead of poll because glibc implements poll but
	not the rest of the stream interface.
	* signal.c [LINUX]: Standardize on the name sigcontext_struct.
	(sys_sigprocmask) [ALPHA]: Handle OSF flavor which is more like
	sigsetmask.
	* term.c (term_ioctl): Use _VMIN, if present, for TC{G,S}ETA*.

	* syscall.c (nerrnos{0,2}): Correct size computation.

	* Makefile.in: Remove dependencies and rules relating to files
 	normally found in the os directory.  Because of the new scheme we
 	don't know precisely where they come from.  Sigh.
	* signalent.sh: Make it work for sunos4, linux, and svr4.
	* {sunos4,linux{,/alpha},svr4}/Makefile.in: Make rules correspond
 	to traditional make syntax.  Add signalent.h to files which can
 	unconditionally be rebuilt.  Prevent signalent.h from being
 	unconditionally being rebuilt since it's customized.
	* {sunos4,linux{,/alpha},svr4}/{ioctlent,errnoent,signalent}.h:
 	Use versions built by {ioctlent,errnoent,signaltent}.sh.
  	* sunos4/ioctlent.sh: Work around sprintf troubles with SunOS
 	4.1.4 and gcc 2.7.2.

	* strace.c (cleanup): Send SIGCONT before SIGTERM because Linux
	1.1.62 doesn't continue a traced child when the parent exits.
	Reported by Matt Day <mday@artisoft.com>.

	* system.c [LINUX]: Include netinet/in.h before arpa/inet.h.

	* util.c (printstr): Fix longstanding bug in notating string
	continuation.

	* strace.c [SVR4] (proc_open): Specifically wait for the child the
	child to go into the execve syscall to avoid spurious traces.
	[LINUX] (detach): Conditionalize the status variable.

	* Makefile.in: Add mips arch.
	* acconfig.h (MIPS): Add mips define.
	* configure.in: Add detection of opsys irix5 and arch mips.  Check
	for prctl function.
	Check for sys/sysconfig.h header.
	* defs.h (MAX_ARGS): Bump maximum syscall arguments from 8 to 32.
	* file.c [SVR4]: Include sys/cred.h.
	(access_flags): Update access flags for SGI.
	(sprinttime): Change type of sprinttime argument from unsigned
	long to time_t.
	* process.c [HAVE_PRCTL]: Include sys/prctl.h.
	[HAVE_PRCTL] (prctl_options, sys_prctl): New for SGI.
	(printsiginfo): Conditionally compile SI_TIMER and SI_MESGQ.
	Cast si_band member to long before printing.
	* signal.c (sigact_flags): Add _SA_BSDCALL for SGI.
	(sigprocmaskcmds): Add SIG_SETMASK32 for SGI.
	* strace.c [SVR4] [MIPS]:
	(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.
