third argument - the old version relies on the compiler to use the same
address for identical strings.
Spotted by segv at netctl dot net in libnbcompat context, details
in PR pkg/32097.
2. return ENAMETOOLONG instead of ENOMEM if name is too long to fit.
3. only decrement cp if we are pointing to the end of the string.
[this fixes the cp truncation of the last char problem reported]
going from:
activate -verbose
to:
reset -activation
results in:
reset -activationverbose"
instead of:
reset -activation
This is because we choose to insert "reset -" before the current line,
and the delete "e -" and insert "ion" in the appropriate place. The
cleareol code did not handle this case properly; we now cleareol to
the maximum number of characters of the first difference, the second
difference and the difference in line length.
- add _citrus_stdenc_get_state_desc() interface to get
encoding-scheme-independent encoder/decoder state descriptions.
- make sure that iconv_std module uses it to judge whether the last
sequences forms complete shift sequences.
- bump minor of i18n_module because of get_state_desc().
which is needed for things like S/KEY. We abuse the SRA_CONTINUE message
passing the password prompt there. That is usually NULL, so SRA
implementations usually ignore it. While I am here, if telnet_gets() fails
[user hit <eof> for example], then we exit.
any threads are created turned out to be not such a good idea.
there are stronger requirements on what has to work in a forked child
while a process is still single-threaded. so take all that stuff
back out and fix the problems with single-threaded programs that
are linked with libpthread differently, by checking if the library
has been started and doing completely different stuff if it hasn't been:
- for pthread_rwlock_timedrdlock(), just fail with EDEADLK immediately.
- for sem_wait(), the only thing that can unlock the semaphore is a
signal handler, so use sigsuspend() to wait for a signal.
- for pthread_mutex_lock_slow(), just go into an infinite loop
waiting for signals.
I also noticed that there's a "sem2" test that has never worked in its
single-threaded form. the problem there is that a signal handler tries
to take a sem_t interlock which is already held when the signal is received.
fix this too, by adding a single-threaded case for sig_trywait() that
blocks signals instead of using the userland interlock.

"NARUSE, Yui" <naruse _at_ airemix.com>, and fixed by MORIYAMA-san.
if the target thread is a zombie.
in all the functions that didn't do so already, verify a pthread_t before
dereferencing it (under #ifdef ERRORCHECK, since these checks are not
mandated by the standard).
clean up some debugging stuff.
call pthread__start() if it hasn't already been called. this avoids
an internal assertion from the library if these routines are used
before any threads are created and they need to sleep.

The name "hash.c" is already used in db/hash/hash.c, and having duplicated
names, aside from it being bad style, breaks the tools/nbcompat build
because it picks the wrong hash.c file. Thanks to greg for helping debug
this.
support in pam_sm_setcred()
With this and a suitably pam-aware screen locker (eg xscreensaver built
with PAM), you now get the nice Windows-style behavior of having
your tickets refreshed (and tokens, with pam_afslog) when you unlock
your screen.
when the strings get expanded we gain an _ from namespace.h. So define a
macro to point to the appropriate include file for the hash function, and
include the hash function later, from the .c file we always include. This
allows us to eliminate the hack of including namespace.h twice as well as
nbtool_config.h.
- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
file sys/nfs/nfs_export.c. The former was becoming large and its code
is always compiled, regardless of the build options. Using the latter,
the code is only compiled in when NFSSERVER is enabled. While doing this,
also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
path and a set of export entries. At the moment it can only clear the
exports list or append entries, one by one, but it is done in a way that
allows setting the whole set of entries atomically in the future (see the
comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
that it becomes file system agnostic. In fact, all this whole thing was
done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
exports initialization; done internally by the kernel when initializing
the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
subsystems can run arbitrary code upon receipt of specific VFS events.
At the moment, this only provides support for unmount and is used to
destroy NFS exports lists from the file systems being unmounted, though it
has room for extension.
Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments
and advice in the development of this patch.
SCHED_OTHER happens to be 0, so this assignment to "int *" succeeds,
and becomes a no-op.
Fix by dereferencing "policy" to do the assignment, thus filling the
return buffer with 0.
