* sysdeps/mach/hurd/readlink.c (__readlink): Don't clobber original
LEN value with io_read result; save it and compare them just in case
the server bogusly returns more than we asked for.
* sysdeps/mach/hurd/recv.c (recv): Likewise for socket_recv.
* sysdeps/mach/hurd/recvfrom.c (recvfrom): Likewise.
* hurd/fd-read.c (_hurd_fd_read): Likewise for io_read.
Initialize NREAD before the RPC. I think this must only have failed
to bomb before because all the servers always return ool data(?).
* sysdeps/mach/hurd/getsockopt.c (getsockopt): Fix inverted sense of
test: *OPTLEN gets BUFLEN iff BUFLEN is lesser. Move that test out of
BUF != OPTVAL condition, since it is a separate issue. Short-circuit
the memcpy and dealloc for BUFLEN==0.
* sysdeps/mach/hurd/setitimer.c (quantize_timeval): New function.
(setitimer_locked): Use it to quantize the timer values. Use
quantized timer values to check if the timeout changed.
* sysdeps/generic/lseek64.c (__libc_lseek64): Renamed from __lseek64.
(__lseek64, lseek64): Make these weak aliases for __libc_lseek64.
* sysdeps/mach/hurd/lseek.c (__libc_lseek): Renamed from __lseek.
(__lseek, lseek): Make these weak aliases for __libc_lseek.
* sysdeps/mach/hurd/fcntl.c (__libc_fcntl): Renamed from __fcntl.
(__fcntl, fcntl): Make these weak aliases for __libc_fcntl.
* sysdeps/mach/hurd/open.c (__libc_open): Renamed from __open.
(__open, open): Make these weak aliases for __libc_open.
* sysdeps/mach/hurd/errnos.awk: Rediddle to collect lines and print
them all at the end, eliding the final comma.
* sysdeps/mach/hurd/bits/errno.h: Regenerated.
* hurd/hurdsig.c (_hurdsig_init): If __hurd_threadvar_stack_mask is
nonzero, use cthread_fork to create the signal thread.
* hurd/msgportdemux.c (_hurd_msgport_receive): Initialize
_hurd_msgport_thread here (to self).
* sysdeps/mach/hurd/fork.c (__fork): When __hurd_sigthread_stack_end
is zero, instead compute child signal thread's starting SP from parent
signal thread's current SP and the threadvar_stack variables.
* hurd/Versions (GLIBC_2.1.3): Add cthread_fork, cthread_detach.
These are now referenced weakly by _hurdsig_init.
* sysdeps/mach/hurd/nfs/nfs.h: New file, empty but for comments.
Its presence lets librpcsvc compile ok. This from Mark Kettenis.
We don't install this file for users.
* sysdeps/mach/hurd/Dist: Add it.
* sysdeps/mach/hurd/Makefile [$(subdir) = sunrpc] (sysdep_headers):
Append nfs/nfs.h here.
* hurd/report-wait.c (describe_port): Return char * and use __stpcpy
to return the location of the null byte written into the string.
(describe_number): Likewise.
(describe_number): Remove assert, not always used with #.
If FLAVOR is null, don't use it.
(describe_number): Take signed argument and print a - if negative.
(_S_msg_report_wait): Report system call number for system calls that
aren't mach_msg. Soup up reporting for mach_msg: If destination port
matches SS->intr_port, bracket port description with [...] to indicate
a Hurd interruptible RPC; if destination port is null, examine the
receive port and report that state; if receive port is also null,
check for timeout and report its value.
* sysdeps/mach/hurd/i386/intr-msg.h (MSG_EXAMINE): Return int that is
zero iff we managed to examine the stack; take new args RCV_NAME,
SEND_NAME, OPTION, and TIMEOUT to fill in with mach_msg args.
* hurd/hurdlookup.c (__hurd_directory_name_split): New function.
(__directory_name_split): New function.
* hurd/hurd.h: Declare them.
* sysdeps/mach/hurd/rmdir.c: Use __directory_name_split instead of
__file_name_split, so we ignore trailing slashes properly.
* sysdeps/mach/hurd/rename.c: Likewise.
* hurd/hurdioctl.c (rectty_dtable): Renamed to install_ctty.
(install_ctty): Do the changing of the cttyid port cell here, inside
the critical section while we holding the dtable lock.
(_hurd_setcttyid, tiocsctty, tiocnotty): Use that instead of changing
the port cell and calling rectty_dtable.
(_hurd_locked_install_cttyid): New function, split out of install_ctty.
(install_ctty): Use it inside a critical section, with the lock held.
* sysdeps/mach/hurd/setsid.c (__setsid): Use
_hurd_locked_install_cttyid to effect the cttyid and dtable changes
after proc_setsid, having held the dtable lock throughout.
* hurd/dtable.c (ctty_new_pgrp): With the dtable lock held, check the
cttyid port for null and bail out early if so. The dtable lock
serializes us after any cttyid change and its associated dtable update.
* sysdeps/mach/hurd/i386/intr-msg.h (INTR_MSG_TRAP): Mark OPTION and
TIMEOUT as outputs of the asm to indicate that the signal thread
might mutate them.
* hurd/intr-msg.c (_hurd_intr_rpc_mach_msg): Short circuit to plain
mach_msg if only sending or only receiving (i.e., not an RPC). When
making an RPC that might get interrupted, save OPTION and the portion
of the message buffer that gets clobbered by an EINTR reply message,
and properly restore them before attempting to retry the request
message send.
* sysdeps/mach/hurd/i386/init-first.c (init): Move the inline
assembler code to switch stacks and call init1 outside this
function. Inside `init' the code was optimized away by gcc
2.95 since it was "clearly" unreachable.
* sysdeps/mach/hurd/i386/trampoline.c (_hurd_setup_sighandler):
Do something similar for the trampoline code.
* sysdeps/mach/hurd/Makefile [stdio-common]: Set inhibit-siglist.
(The code this disables is entirely gone in the main branch,
so this change does not need to be propagated from the 2.1 branch.)
* sysdeps/mach/hurd/brk.c (static_data_start): New variable.
(_hurd_set_brk, init_brk): Use that instead of &__data_start.
Initialize it from &__data_start if defined, or else &_end.
* sysdeps/unix/sysv/linux/siglist.c: Moved to ...
* sysdeps/gnu/siglist.c: ... here.
Use <siglist.h> instead of "siglist.h", to ensure sysdeps-search.
Use <bits/wordsize.h> instead of <sizes.h> to determine PTR_SIZE_STR.
* sysdeps/gnu/siglist.h: New file, contents from linux version.
Add entry for SIGLOST protected by #ifdef.
* sysdeps/unix/sysv/linux/siglist.h: Just #include that file,
and define OLD_SIGLIST_SIZE_STR.
* sysdeps/mach/hurd/siglist.h: New file, likewise.
* Makeconfig (static-start-installed-name): Set to
$(start-installed-name) if not defined.
(+link-static): Use $(static-start-installed-name) instead of
$(start-installed-name).
* sysdeps/mach/hurd/i386/Makefile (static-start-installed-name):
Set to crt0.o.
* sysdeps/mach/hurd/fork.c (__fork): Make use of `insert_type' when
inserting a send right into the child instead of unconditionally
copying the send right.
* sysdeps/mach/hurd/getdents.c (__getdirentries): Remove
implementation and just always fail with ENOSYS. This entry point is
obsolete. Add link warning to that effect.
* sysdeps/mach/hurd/i386/Makefile [$(subdir) = csu]
(CFLAGS-initfini.s): New variable, add -DWEAK_GMON_START.
This does for Hurd/i386 what the 1998-09-08 change did for Linux/i386.
* sysdeps/mach/hurd/Makefile: Undo last change.
[$(subdir) = mach] (lib-noranlib): Depend on libmachuser-link.so.
[$(subdir) = hurd] (lib-noranlib): Depend on libhurduser-link.so.
* mach/Machrules (+preinit, +postinit, +interp,
LDFLAGS-$(interface.so)): Variables removed. Interface libraries get
linked just like other shared libraries.
(interface.so): Fix typo in defn, so it works.
($(objpfx)$(interface.so)): Make it depend on libc.so.
* sysdeps/mach/hurd/fcntl.c (__fcntl: case F_GETLK,F_SETLK,F_SETLKW):
Support whole-file locking (only) by using the file_lock RPC. This
has very wrong semantics, but is better than nothing for the time
being. (Correct POSIX.1 locking will require new RPCs in the Hurd
protocols that will be somewhat hairy to specify.)
* sysdeps/mach/hurd/poll.c (__poll): Correctly pass NULL to
_hurd_select if TIMEMOUT is -1.
1999-03-15 Mark Kettenis <kettenis@gnu.org>
* sysdeps/mach/hurd/recvfrom.c (recvfrom): Allow ADDR to be NULL.
* sysdeps/mach/hurd/ioctl.c (__ioctl): Move the marshalling of the
arguments into the request message buffer inside `send_rpc'
subfunction. We must repeat the marshalling when retrying the RPC
after a SIGTTOU delivery.
* sysdeps/mach/hurd/bits/fcntl.h
[__USE_GNU] (O_NOFOLLOW, O_DIRECTORY): New macros.
* hurd/hurdlookup.c (__hurd_file_name_lookup): If O_NOFOLLOW is set,
set O_NOTRANS as well.
(__hurd_file_name_lookup_retry): At successful end of lookup,
if O_NOFOLLOW set, io_stat the resultant port and fail with ENOENT if
it is a translated node not owned by root.
(__hurd_file_name_lookup): If O_DIRECTORY is set, put a trailing slash
on the file name passed to LOOKUP.
* sysdeps/mach/hurd/getsockname.c (getsockname): Set *LEN to the
actual length if the adress length is smaller than the input
value. Change type of *LEN paramater to socklen_t.
* sysdeps/mach/hurd/getpeername.c (getpeername): Likewise.
* sysdeps/mach/hurd/accept.c (accept): Likewise.
* sysdeps/mach/hurd/recvfrom.c (recvfrom): Likewise.
* sysdeps/mach/hurd/sendto.c (sendto): Change type of ADDR_LEN
paramater to socklen_t.
