ChangeLog

2001-03-07  John Hughes <john@Calva.COM>

  * desc.c: On FreeBSD flock structure uses 64 bit offsets.
  * file.c: On FreeBSD use stat64 and pals instead of stat.
  * freebsd/syscalls.print: use stat64, lstat64 and fstat64.
  * freebsd/i386/syscall.h: ditto.
  * freebsd/i386/syscallent.h: ditto.

2001-03-07  John Hughes <john@Calva.COM>

  * file.c: merge missing part of Harald Böhme's solaris patches,
    was only declaring sys_{stat64,lstat64,fstat64} on linux!

2001-03-07  John Hughes <john@Calva.COM>

  * svr4/dummy.h: fix multiple define warning on non LFS64 systems.
  * svr4/syscallent.h: pread/pwrite are TF calls.

2001-03-07  John Hughes <john@Calva.COM>

  * defs.h: add ALIGN64 macro to cope with FreeBSD's strange insistence
    on alignment for off_t (64 bit) arguments.  Also simplify get64 so
    we don't need to know endianness of long long.
  * file.c: FreeBSD now uses 64 bit versions of lseek, truncate,
    ftruncate, allows reduction in numvber of horrid #if's
  * io.c: FreeBSD now uses 64 bit versions of pread, pwrite.
  * mem.c: FreeBSD now uses 64 bit version of mmap.
  * freebsd/syscalls.print: use 64 bit versions of various syscalls.
  * freebsd/i386/syscall.h: use 64 bit versions of various syscalls.
  * freebsd/i386/syscallent.h: use 64 bit versions of various syscalls.

2001-03-06  John Hughes <john@Calva.COM>

  * file.c: Implement truncate64 and ftruncate64
  * svr4/dummy.h: add dummies for truncate64 and ftruncate64 for non
    LFS64 systems.
  * svr4/syscall.h: add declarations for truncate64 and ftruncate64.

2001-03-06  John Hughes <john@Calva.COM>

    syscall master file).

2001-03-06  John Hughes <john@Calva.COM>

  * syscall.c: fix for FreeBSD 4.1 (SYS_semconfig has disappeared).  Also
    zap incorrect syscall subarg range check.

2001-03-06  John Hughes <john@Calva.COM>

    signal.c, syscall.c, svr4/dummy.h, svr4/syscall.h, svr4/syscallent.h:
    merge Harald Böhme's solaris patches (_LFS64_LARGEFILE and kernel aio
    mostly).

	* 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>

	* version.c: Version 3.0.14 is released.

	* aclocal.m4 (AC_STRUCT_MSG_CONTROL): New macro.
	* configure.in: Add call to AC_STRUCT_MSG_CONTROL.
	* net.c (printmsghdr): Handle BSD 4.3 and 4.4 msghdr members
 	differently.
	Reported by Henrik Storner <storner@osiris.ping.dk>.

	* configure.in: (AC_CHECK_{HEADERS,FUNCS}): Add checks for
 	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*.
	* util.c (umoven, umovestr): Move data in long-sized chunks

	(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.
