bouyer 52497e180a Remplace kern.shortcorename sysctl with a more flexible sheme,
core filename format, which allow to change the name of the core dump,
and to relocate it in a directory. Credits to Bill Sommerfeld for giving me
the idea :)
The default core filename format can be changed by options DEFCORENAME and/or
kern.defcorename
Create a new sysctl tree, proc, which holds per-process values (for now
the corename format, and resources limits). Process is designed by its pid
at the second level name. These values are inherited on fork, and the corename
fomat is reset to defcorename on suid/sgid exec.
Create a p_sugid() function, to take appropriate actions on suid/sgid
exec (for now set the P_SUGID flag and reset the per-proc corename).
Adjust dosetrlimit() to allow changing limits of one proc by another, with
credential controls.

drochner 192b3c733c Build libraries for kernel/standalone code from within their compilation
directories and use .PATH to lookup the source files.
(Formerly, the libs were built from the source dirs, with MAKEOBJDIR
set to the compilation directory.)
This solves 2 problems:
-"mkdep" and "make" are now consistent about the file lookup, this fixes
 bad interactions with amd reported in PR bin/7374 (Arne Juul) and
 lossage reported by Andrew Gillham ("obj" dirs and relative paths still
 don't work well together)
-kernel compile trees can be moved around without forcing a new
 "make depend" - fixing PR kern/4021 by Martin Husemann

thorpej e3669c3393 Add "use counting" to file entries. When closing a file, and it's reference
count is 0, wait for use count to drain before finishing the close.

This is necessary in order for multiple processes to safely share file
descriptor tables.

christos b69c7692af From cgd again: pbuf == path on failure. 1999-04-27 15:42:37 +00:00
christos c4f1bab08e Make the usage consistant and document it:
if the path was given in a user buffer, return the new path in
a user buffer.
if the path was given in a kernel buffer, allocate a new kernel buffer
to return the new path; the caller is responsible for freeing the buffer
if we fail always set the new path to NULL.
This usage broke when I adde the /../ shortcut. Noted by cgd.

cgd f12f795592 a quick hack to make generating errno conversion tables from our and other
systems' headers a bit easier.  leaves much to be desired, but it's better
than nothing.

comment (we're converting from a new to an old struct stat).

christos 5e44086190 Provide a way for compat programs to specify files in the normal tree.
We do this using a trick similar to mach's /../; if a path is given as
/..<absolute-path-name>, then we return <absolute-path-name>

drochner c22ef79250 solve the COMPAT_OLDSOCK/MSG_COMPAT problem differently:
The source files which need MSG_COMPAT define COMPAT_OLDSOCK.

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.

kleink c6ef57702d UIO_MAXIOV -> IOV_MAX 1998-08-04 12:19:15 +00:00
kleink 3d9b4a4320 Fix two off-by-one bugs, both present in each recvmsg(2) and sendmsg(2):
* the first one would cause an unnecessary malloc() of iovec storage for
  a msg_iovlen of UIO_SMALLIOV although the required amount of memory has
  been allocated on the stack.
* the second one would cause a recvmsg() or sendmsg() with a msg_iovlen of
  UIO_MAXIOV to fail with EMSGSIZE, which is also a violation of XNS5.

mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

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 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.
