christos 23c15f1578 Don't set P_SUGID if the calls to set{e,}{u,g}id(), setreuid(),
setgroups() did not result in actual changes. This has the nice
side effect that we don't needlesly allocate new credential and
resource limit data structures.

This is so that non setuid programs that call seteuid(getuid()),
don't end up setting P_SUGID, resulting in broken behavior [i.e.
non setuid ssh, doesn't read ~/.hostaliases...].

This is a good candidate for a pullup, if someone reviews it.

sommerfeld 40339b39f9 Reduce use of curproc in several places:
- Change ktrace interface to pass in the current process, rather than
p->p_tracep, since the various ktr* function need curproc anyway.

 - Add curproc as a parameter to mi_switch() since all callers had it
handy anyway.

 - Add a second proc argument for inferior() since callers all had
curproc handy.

Also, miscellaneous cleanups in ktrace:

 - ktrace now always uses file-based, rather than vnode-based I/O
(simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD.
Do non-blocking I/O, and yield a finite number of times when receiving
EWOULDBLOCK before giving up.

 - move code duplicated between sys_fktrace and sys_ktrace into ktrace_common.

 - simplify interface to ktrwrite()

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.

mycroft 402ecc3fed Clean up code from last commit. 1997-11-10 08:26:09 +00:00
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 *".

From Chris Demetriou <cgd@pa.dec.com>.

mrg 5abbf990f3 Change reboot(2) to take two arguments: bootopt like normal and also
a boot string for firmware that can do this, such as the SPARC and
the sun3 models.  It is currently silently ignored on all other
hardware now, however.  The MD function "boot()" has been changed to
also take a char *.
