minoura f6051edef5 Add native issetugid() call.
Implementation from compat/freebsd.

mrg a6f7a7855f implement lchflags(2), which does the chflags(2) dance without following
symlinks, and thus can operate on symlinks.  remove a bogus comment in
chflags(1) that claims symlinks do not have file flags.

XXX: todo -- make chflags(1) use lchflags(2) when given the right options.

christos 3cbe025990 __semctl13 -> ____semctl13 because this now is not called directly.
The fourth argument to it is a pointer to union semun not union semun,
because passing structs and unions to syscalls cannot be handled portably.

mycroft db70ed30f4 Use proper varargs format for __semctl13. 2000-01-23 01:01:30 +00:00
thorpej dc8ecaa15b Overhaul of the SVID IPC facilities, primarily to use the types specified
by the Single UNIX Specification version 2, rather than the SVR2-derived
types.  While I was here, I did a namespace sweep to expose the constants
and strucutures, and structure members described by SUSv2; documentation
updates coming shortly.

Fixes kern/8158.

sommerfe 095cd96cd5 Change namei cache to record vnode->(parent,name) entries (for directories).
Add kernel implementation of getcwd() which uses this cache, falling
back to reading the filesystem on a cache miss.
Along for the ride: add new VOP_FSYNC flag FSYNC_RECLAIM indicating
that a reclaim is being done, so only a "shallow" fsync is needed.

kleink dfffb2f357 * Due to addition and use of socklen_t, make the socket option and address
arguments passed to accept(), bind(), connect(), getpeername(), getsockname(),
getsockopt(), recvfrom(), sendto() and sendmsg() unsigned, which also elimiates
a few casts.
* Reflect the (now) signedness of msg_iovlen, which necessiates the addition
of a few casts.

mycroft 89ea1fcbdd Version sys_sigreturn, to avoid breaking programs that use it explicitly. 1998-09-12 00:47:12 +00:00
mycroft fb526e055c Substantial signal handling changes:
* Increase the size of sigset_t to accomodate 128 signals -- adding new
  versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
  sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
  sys_sigpending() and sys_sigsuspend() into separate functions, and call them
  from all the emulations rather than hard-coding everything.  (Avoids uses
  the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
  pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
  bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
  in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.

Note: Only code touched by the i386 port has been modified.  Other ports and
emulations need to be updated.

thorpej d4e618b3a5 Argh, pad the off_t args in pread/pwrite/preadv/pwritev. System call
numbers don't change since the window of brokenness was so small (1 day).

thorpej f0dda0d383 Add positional read and write system calls:
- pread() (#173) and pwrite() (#174), which are defined by XPG4.2.  System
  call numbers match Solaris.
- preadv() (#289) and pwritev() (#290), which are the positional cousins
  of readv() and writev(), but not defined by any standard.

kleink 3a1500efe9 Per X/Open CAE Spec Issue 5 Version 2, change the buffer size argument of
readlink() from type `int' to type `size_t'.  This isn't an ABI change, since
the calling convention of our only LP64 platform (the Alpha) already promotes
this argument to a `long'.

This may not be the final action on this matter; readlink() still returns
an `int', which may change in a future revision of the standard.

kleink a255f23ee3 In XPG4.2, the ss_size member of type stack_t (struct sigaltstack) is specified
to be of type size_t; since this imposes an interface change on the Alpha
(sizeof(int) != sizeof(size_t)), allocate a new system call number and make
the previous version a compatibility system call.

thorpej 97d2a58201 Fix slight argument bogosity with getgroups(), setgroups(), select(),
and swapctl().  For the former three, they use an 'int' in their user-land
prototype which was a 'u_int' in the kernel, which screwed up automatic
generation/checking of lint syscall stubs.  For the latter, the user-land
prototype uses a "const char *", but the syscall just used "char *".

thorpej 14cd99880c Fix the shared library versioning snafu caused by the recent changes
to the stat(2) family and msync(2).  This uses a primitive function
versioning scheme.

This reverts the libc shared library major version from 13 to 12, and
adds a few new interfaces to bring us to libc version 12.20.
