746 2001-10-16 John Hughes <john@Calva.COM>
748 * util.c (umovestr): UnixWare (svr4?) returns 0 when trying
749 to read unmapped page. Make it possible to strace ksh.

765 new ioctlent.h generation scheme.
767 * linux/syscall.h (sys_clone2): Declare.
768 [IA64] Define ia32 socket, ipc, and extra syscall numbers.
770 * linux/ioctlent.sh (regexp): Also handle <asm/ioctls.h> so we
771 don't miss the tty ioctls (unfortunately, some of the sound timer
772 ioctls are in conflict with them!).

775 (clrbpt) [IA64]: Ditto.
777 * syscall.c (internal_syscall): Handle SYS_clone2, SYS32_wait4,

804 * signal.c (parse_sigset_t): New function.
805 (sigishandled): Fix off-by-one bug by using parse_sigset_t() and

816 always the same as r32 (e.g., consider inlined syscalls).
818 2001-09-28 John Hughes <john@Calva.COM>
820 * process.c: FreeBSD-CURRENT no longer has PT_READ_U, and anyway we
821 were showing it as PT_WRITE_U! Fix from Maxime Henrion.
823 2001-09-18 John Hughes <john@Calva.COM>
825 * net.c: fix display of sockaddr structures, sometimes too many "}",
826 sometimes too few. Fix suggested by Richard Kettlewell.
828 2001-08-19 Wichert Akkerman <wakkerma@debian.org>
830 * signal.c: do not include asm/sigcontext.h on IA64 since it gets
831 the struct from bits/sigcontext.h already which signal.h includes.
833 2001-08-03 Wichert Akkerman <wakkerma@debian.org>
835 * linux/ioctlent.sh: change regexps so we catch sound ioctls as well in

841 2001-08-03 Wichert Akkerman <wakkerma@debian.org>
843 * Linux/**/syscallent.h: synchronize section for fcntl and use sys_fcntl

876 routine from net.c (duplicate of tprint_iov in util.c).
878 2001-07-02 Wichert Akkerman <wakkerma@debian.org>
880 * config.{guess,sub}: updated
882 2001-05-15 John Hughes <john@Calva.COM>

887 2001-05-15 John Hughes <john@Calva.COM>
889 * util.c: Don't run off the end of valid memory in umovestr when
890 USE_PROCFS. Important for FREEBSD systems (which seem to have an
891 unmapped page just after the args/env area).
893 2001-04-18 John Hughes <john@Calva.COM>
895 * configure.in: test for sys/nscsys.h, the non-stop clusters includes.
896 * process.c: handle rfork{1,all} and rexecve calls on non-stop clusters.
897 * syscall.c: treat rfork{1,all} and fork{1,all} as fork like calls.

968 * process.c, syscall.c: work around double define of fpq, fq and fpu

1532 is similar enough to i386 to not need it's own subdirectory
1533 + add support for sendfile and mremap syscalls for Linux
1534 * Merge in patches from Sascha Schumann <sascha@schumann.2ns.de>
1535 + ioctls.h vs sys/ioctl.h on Alpha platform

1538 + several other casts changed
1539 + correct ARM/POWERPC architecture defines in acconfig.h
1540 * Merge in patches from Morten Welinder <terra@diku.dk>

1551 Fri Apr 16 02:18:05 CEST 1999 Wichert Akkerman <wakkerma@debian.org>

1555 * Change references to LINUX into linux in file.c
1556 * Fix include for LDT in mem.c
1558 Thu Apr 15 22:28:15 CEST 1999 Wichert Akkerman <wakkerma@debian.org>

1562 * Incorporate all changes already made in the Debian strace package:
1563 + compiles with more Linux kernels
1564 + added support for more Linux architectures
1565 + add support for a lot of extra syscalls
1566 + fix some problems with hanging children
1567 + check stray syscall after execv
1568 + decode capget and capset arguments
1569 + add more constants to net.c
1570 + detect ROSE networking
1571 + add more protocol families to domains
1573 + added MSG_PROXY and MSG_CTRUNC to msg_flags
1574 + added SO_BSDCOMPAT and SO_REUSEPORT to sockoptions
1575 + added IP, IPX and TCP-options
1576 + added IP, IPX and TCP support to get-/setsockopt()
1578 + updated handling of signals
1580 Sun Oct 27 22:28:00 1996 J. Richard Sladkey <jrs@world.std.com>
1582 * util.c (umovestr) [LINUX]: Handle Linux like SunOS4
1583 instead of SVR4. That is, read a few bytes at a time
1584 to avoid overrunning the end of the stack.
1586 Fri May 31 01:48:49 1996 J. Richard Sladkey <jrs@world.std.com>
1588 * version.c: Version 3.1 is released.
1590 Thu May 23 01:04:43 1996 J. Richard Sladkey <jrs@world.std.com>
1592 * aclocal.m4 (AC_DECL_SYS_ERRLIST): Try looking in stdio.h
1593 as well since that's where glibc declares it. Go figure.
1594 * signal.c (sys_sigreturn) [ALPHA]: Use sigcontext
1595 instead of sigcontext_struct since glibc v5+ apparently
1596 plays games with the native OS namespace.
1597 From David Mosberger-Tang <davidm@AZStarNet.com>.
1599 Mon May 20 23:17:14 1996 J. Richard Sladkey <jrs@world.std.com>
1601 * version.c: Version 3.0.14 is released.
1603 * aclocal.m4 (AC_STRUCT_MSG_CONTROL): New macro.
1604 * configure.in: Add call to AC_STRUCT_MSG_CONTROL.
1605 * net.c (printmsghdr): Handle BSD 4.3 and 4.4 msghdr members
1607 Reported by Henrik Storner <storner@osiris.ping.dk>.
1609 * configure.in: (AC_CHECK_{HEADERS,FUNCS}): Add checks for
1610 sys/filio.h and sys/stream.h and remove check for poll.
1611 * desc.c (decode_select, sys_select, sys_oldselect) [LINUX]:
1612 Handle old and new styles of argument passing for select on Linux.
1613 * ioctl.c, stream.c: Conditionalize stream code on presence of
1614 sys/stream.h instead of poll because glibc implements poll but
1615 not the rest of the stream interface.
1616 * signal.c [LINUX]: Standardize on the name sigcontext_struct.
1617 (sys_sigprocmask) [ALPHA]: Handle OSF flavor which is more like
1619 * term.c (term_ioctl): Use _VMIN, if present, for TC{G,S}ETA*.
1620 * util.c (umoven, umovestr): Move data in long-sized chunks
1621 at a time, instead of hard coding it to be 4.

1628 * configure.in (AC_CHECK_HEADERS): Add check for asm/sigcontext.h.
1629 * signal.c [HAVE_ASM_SIGCONTEXT_H]: Conditionally include
1630 asm/sigcontext.h to define sigcontext_struct and don't define it
1631 locally if the header is present.
1633 * syscall.c (nerrnos{0,2}): Correct size computation.
1635 * Makefile.in: Remove dependencies and rules relating to files
1636 normally found in the os directory. Because of the new scheme we
1637 don't know precisely where they come from. Sigh.
1638 * signalent.sh: Make it work for sunos4, linux, and svr4.
1639 * {sunos4,linux{,/alpha},svr4}/Makefile.in: Make rules correspond
1640 to traditional make syntax. Add signalent.h to files which can
1641 unconditionally be rebuilt. Prevent signalent.h from being
1642 unconditionally being rebuilt since it's customized.
1643 * {sunos4,linux{,/alpha},svr4}/{ioctlent,errnoent,signalent}.h:
1644 Use versions built by {ioctlent,errnoent,signaltent}.sh.
1645 * sunos4/ioctlent.sh: Work around sprintf troubles with SunOS
1646 4.1.4 and gcc 2.7.2.

1655 * ioctl.c, ioctlsort.c (compare): Perform explicit checking
1656 for less, greater, and equal since subtraction on two's
1657 complement numbers isn't an order relation (it isn't transitive)!
1658 * linux/Makefile.in: Add rules for the signalent.h file.
1659 * linux/alpha/Makefile.in: New file.
1661 Sun May 19 01:12:28 1996 J. Richard Sladkey <jrs@world.std.com>

1673 based on personality.
1674 * {sunos4,svr4,linux{,/alpha}}/signalent.h: New files.
1675 Suggested by Tom Dyas <tdyas@eden.rutgers.edu>.

1690 Reported by Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.
1692 * linux/syscall.h (sys_utimes): Fix a typo in the declaration.
1693 From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.

1697 * version.c: Version 3.0.10 is released.
1699 * Makfile.in: Add os/arch to includes so that a given arch
1700 (like alpha) can override the native arch (like i386).
1701 * configure.in: Check for sendmsg.
1703 * net.c: Make sendmsg and recvmsg dependent on an autoconf
1704 test. Reported by Michael E Chastain <mec@duracef.shout.net>.
1706 * acconfig.h, configure.in: Detect the alpha.
1707 * ioctl.c: Handle the alpha.
1708 * defs.h: Make some members long for the alpha. Define
1709 some register nicknames. Add support for WAITEXECVE.
1710 * file.c [ALPHA]: Support the alpha for statfs. Add
1711 osf_statfs and osf_fstatfs for the alpha. Make damn sure
1712 major and minor results are suitable for passing to printf.
1713 * signal.c, syscall.c: Support the alpha.
1714 * process.c: Add alpha user offsets.
1715 * most files: Use %l? for printf arguments since
1716 most are now longs for the alpha.
1717 * linux/alpha/{errnoent.h,ioctlent.{h,sh},syscallent.h}:
1719 From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.

1744 * time.c [LINUX]: Explicitly include linux/version.h.
1746 * strace.c (main): Don't let them even *try* to
