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.

cgd acad90d846 * (slight) general cleanup
* change in-kernel syscall prototypes to match user-land prototypes in
  the following ways:
    + add 'const' where appropriate.
    + make the following "safe" type changes where appropriate:
	caddr_t -> struct msghdr *
	caddr_t -> struct sockaddr *
	caddr_t -> void *
	char * -> void *
	int -> uid_t (safe because uid_t not used as index/count)
	int -> gid_t (safe because gid_t not used as index/count)
	u_int -> size_t
    + change "int" to "u_long" in flags arguments to chflags() and
      fchflags().  This is safe because the arguments are used as
      flag bits and there's nothing that would cause the top bit
      of the int to be set yet, and because the user-land definitions
      already specified u_long, so a u_long's worth of argument was
      already being passed in.

cgd 997ec138ad change ntp_gettime's struct ntptimeval *'s name to match kern_ntptime.c 1996-12-22 07:47:43 +00:00
cgd c99936a735 * fix return types. previously, most things returned 'int.' which was
wrong for a bunch of functions:
	void:		sys_exit, sys_sync
	ssize_t:	sys_read, sys_write, sys_recvmsg, sys_sendmsg,
			sys_recvfrom, sys_readv, sys_writev, sys_sendto
	long:		sys_pathconf, sys_fpathconf
	void *:		sys_shmat

* Note that sys_open, sys_ioctl, and sys_fcntl are defined such that their
  last argument is optional.

These changes should not have any real effect, because right now this
information is not actually used for anything.

It had implications that didn't occur to me at the time.  *sigh*
