0287aa1cee Revert to using yp_order() to probe for master.paswd.by* maps and
don't probe the server at all for passwd.by* maps. This fixes
interoperability with the Services For UNIX NIS server (which is
really a front end to Captive^WActiveDirectory). This server
incorrectly returns success for all YPPROC_MASTER requests,
even for maps that don't exist, which makes it impossible to
(ab)use it to probe for the existence of the master.passwd.by*
maps.

This is a little kludgey, but basically restores the original
behavior of getpwent.c as it is in -stable, and works around both
the lack of YPPROC_ORDER on NIS+ servers as well as the broken
YPPROC_MASTER on Services For UNIX servers.

596ea21c7f Add a preemption point when a mutex or condition variable is
handed-off/signaled to a higher priority thread.  Note that when
there are idle KSEs that could run the higher priority thread,
we still add the preemption point because it seems to take the
kernel a while to schedule an idle KSE.  The drawbacks are that
threads will be swapped more often between CPUs (KSEs) and
that there will be an extra userland context switch (the idle
KSE is still woken and will probably resume the preempted
thread).  We'll revisit this if and when idle CPU/KSE wakeup
times improve.

090b336154 o Eliminate upcall for PTHREAD_SYSTEM_SCOPE thread, now it
is system bound thread and when it is blocked, no upcall is generated.

o Add ability to libkse to allow it run in pure 1:1 threading mode,
  defining SYSTEM_SCOPE_ONLY in Makefile can turn on this option.

o Eliminate code for installing dummy signal handler for sigwait call.

o Add hash table to find thread.

4afa371832 Very big makeover in the way telnet, telnetd and libtelnet are built.
Previously, there were two copies of telnet; a non-crypto version
that lived in the usual places, and a crypto version that lived in
crypto/telnet/. The latter was built in a broken manner somewhat akin
to other "contribified" sources. This meant that there were 4 telnets
competing with each other at build time - KerberosIV, Kerberos5,
plain-old-secure and base. KerberosIV is no longer in the running, but
the other three took it in turns to jump all over each other during a
"make buildworld".

As the crypto issue has been clarified, and crypto _calls_ are not
a problem, crypto/telnet has been repo-copied to contrib/telnet,
and with this commit, all telnets are now "contribified". The contrib
path was chosen to not destroy history in the repository, and differs
from other contrib/ entries in that it may be worked on as "normal"
BSD code. There is no dangerous crypto in these sources, only a
very weak system less strong than enigma(1).

Kerberos5 telnet and Secure telnet are now selected by using the usual
macros in /etc/make.conf, and the build process is unsurprising and
less treacherous.

68d0d87b81 _start() needed to be written in assembly. See crt1.S. 2003-07-14 03:05:42 +00:00
Marcel Moolenaar
db7ffe67c6 Rewite _start(). We cannot use a C function due to the fact that we
don't call it according to the runtime specification and especially
WRT to gp this can cause trouble. The gcc 3.3.1 import broke the
ia64 runtime because the compiler saved gp prior to us being able
to set it properly. Restoring gp after the calls would then invalidate
gp and cause segmentation faults later on.
By rewriting _start() as an assembly function, we also avoided even
more gcc dependences, by trying to use gcc specific features to work
around the problem.
This version of _start() does not reference _DYNAMIC. We register the
cleanup function when it's a non-NULL pointer. The kernel will always
pass a NULL pointer and dynamic linkers may pass a non-NULL pointer.

The machine independent code to set __progname now unfortunately is
written in assembly. So be it.

6fbddb9816 Don't resume sigwait thread If signal is masked. 2003-07-09 22:30:55 +00:00
David Xu
d80384bc8d POSIX says if a thread is in sigwait state, although a signal may not in
its waitset, but if the signal is not masked by the thread, the signal
can interrupt the thread and signal action can be invoked by the thread,
sigwait should return with errno set to EINTR.
Also save and restore thread internal state(timeout and interrupted)
around signal handler invoking.
