239 Fri Sep 10 04:35:16 CEST 1999 Wichert Akkerman <wakkerma@debian.org>
241 * #define USE_GNU before including file.c so we get some extra O_* flags

261 * configure.in: Allow compilation in a different directory

267 * syscall.c: Likewise.
269 Wed Aug 4 18:01:50 CEST 1999 Wichert Akkerman <wakkerma@debian.org>

330 * linux/sparc/syscall.h: Update used sparc-linux syscalls.
331 * linux/sparc/syscallent.h: Match 2.2.9 system calls.
332 * file.c: sparc-linux asm/stat.h uses dev_t etc. types,

357 + some layout and other minor fixes
358 + add some m68k-specific things to linux/syscallent.h. Note that m68k

385 Thu Apr 15 22:28:15 CEST 1999 Wichert Akkerman <wakkerma@debian.org>

409 * util.c (umovestr) [LINUX]: Handle Linux like SunOS4
410 instead of SVR4. That is, read a few bytes at a time
411 to avoid overrunning the end of the stack.
413 Fri May 31 01:48:49 1996 J. Richard Sladkey <jrs@world.std.com>
415 * version.c: Version 3.1 is released.
417 Thu May 23 01:04:43 1996 J. Richard Sladkey <jrs@world.std.com>
419 * aclocal.m4 (AC_DECL_SYS_ERRLIST): Try looking in stdio.h
420 as well since that's where glibc declares it. Go figure.
421 * signal.c (sys_sigreturn) [ALPHA]: Use sigcontext
422 instead of sigcontext_struct since glibc v5+ apparently
423 plays games with the native OS namespace.
424 From David Mosberger-Tang <davidm@AZStarNet.com>.
426 Mon May 20 23:17:14 1996 J. Richard Sladkey <jrs@world.std.com>
428 * version.c: Version 3.0.14 is released.
430 * aclocal.m4 (AC_STRUCT_MSG_CONTROL): New macro.
431 * configure.in: Add call to AC_STRUCT_MSG_CONTROL.
432 * net.c (printmsghdr): Handle BSD 4.3 and 4.4 msghdr members
434 Reported by Henrik Storner <storner@osiris.ping.dk>.
436 * configure.in: (AC_CHECK_{HEADERS,FUNCS}): Add checks for
437 sys/filio.h and sys/stream.h and remove check for poll.
438 * desc.c (decode_select, sys_select, sys_oldselect) [LINUX]:
439 Handle old and new styles of argument passing for select on Linux.
440 * ioctl.c, stream.c: Conditionalize stream code on presence of
441 sys/stream.h instead of poll because glibc implements poll but
442 not the rest of the stream interface.
443 * signal.c [LINUX]: Standardize on the name sigcontext_struct.
444 (sys_sigprocmask) [ALPHA]: Handle OSF flavor which is more like
446 * term.c (term_ioctl): Use _VMIN, if present, for TC{G,S}ETA*.
447 * util.c (umoven, umovestr): Move data in long-sized chunks
448 at a time, instead of hard coding it to be 4.
449 From David Mosberger-Tang <davidm@AZStarNet.com>.
451 Mon May 20 01:19:36 1996 J. Richard Sladkey <jrs@world.std.com>

456 * signal.c [HAVE_ASM_SIGCONTEXT_H]: Conditionally include
457 asm/sigcontext.h to define sigcontext_struct and don't define it
458 locally if the header is present.
460 * syscall.c (nerrnos{0,2}): Correct size computation.
462 * Makefile.in: Remove dependencies and rules relating to files
463 normally found in the os directory. Because of the new scheme we
464 don't know precisely where they come from. Sigh.
465 * signalent.sh: Make it work for sunos4, linux, and svr4.
466 * {sunos4,linux{,/alpha},svr4}/Makefile.in: Make rules correspond
467 to traditional make syntax. Add signalent.h to files which can
468 unconditionally be rebuilt. Prevent signalent.h from being
469 unconditionally being rebuilt since it's customized.
470 * {sunos4,linux{,/alpha},svr4}/{ioctlent,errnoent,signalent}.h:
471 Use versions built by {ioctlent,errnoent,signaltent}.sh.
472 * sunos4/ioctlent.sh: Work around sprintf troubles with SunOS
475 Sun May 19 17:14:09 1996 J. Richard Sladkey <jrs@world.std.com>
477 * configure.in, Makefile.in: Add OSARCH concept to finish
478 build support for the alpha.
479 * Makefile.in, linux/Makefile.in: Rewrite clean, distclean,
480 and maintainer-clean rules.
481 * defs.h, ioctlsort.c: Make ioctl code member unsigned.
482 * ioctl.c, ioctlsort.c (compare): Perform explicit checking
483 for less, greater, and equal since subtraction on two's
484 complement numbers isn't an order relation (it isn't transitive)!
485 * linux/Makefile.in: Add rules for the signalent.h file.
486 * linux/alpha/Makefile.in: New file.
488 Sun May 19 01:12:28 1996 J. Richard Sladkey <jrs@world.std.com>
490 * version.c: Version 3.0.12 is released.
492 * linux{,alpha}/ioctlent.sh: Tweak for recent kernels.
493 From Michael E Chastain <mec@duracef.shout.net>.
495 * defs.h (SUPPORTED_PERSONALITES, DEFAULT_PERSONALITY): New.
496 * syscall.c (set_personality): New.
497 * strace.c (main): Call set_personality.
498 * defs.h, syscall.c, ioctl.c, signal.c: Make sysent, errnoent,
499 ioctlent, and signalent indirect pointers and redirect them
500 based on personality.
501 * {sunos4,svr4,linux{,/alpha}}/signalent.h: New files.
502 Suggested by Tom Dyas <tdyas@eden.rutgers.edu>.
504 * util.c (upeek): Handle case where ptrace returns a long
505 and sizeof(long) != sizeof(int).
506 From Richard Henderson <richard@twiddle.tamu.edu>
508 Fri May 17 21:03:36 1996 J. Richard Sladkey <jrs@world.std.com>
510 * version.c: Version 3.0.11 is released.
512 * many files: Fix more printf warnings for other platforms.
514 * ipc.c (sys_msgrcv) [LINUX]: Conditionalize definition of ipc_wrapper.
516 * linux/dummy.h: Handle missing library support for {send,recv}msg.
517 Reported by Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.
519 * linux/syscall.h (sys_utimes): Fix a typo in the declaration.
520 From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.
522 Fri May 17 00:50:06 1996 J. Richard Sladkey <jrs@world.std.com>
524 * version.c: Version 3.0.10 is released.
526 * Makfile.in: Add os/arch to includes so that a given arch
527 (like alpha) can override the native arch (like i386).
528 * configure.in: Check for sendmsg.
