NIS map which is present on SunOS NIS servers with the SunOS C2 security
hack^Woption installed. I'm convinced that the C2 security option restricts
access to the passwd.adjunct.byname map in the same way that I restrict
access to the master.passwd.{byname,buid} maps (checking for reserved ports),
which means that we should be able to handle passwd.adjunct.byname map
correctly.
If _havemaster() doesn't find a master.passwd.byname map, it will now
test for a passwd.adjunct.byname map before defaulting back to the
standard non-shadowed passwd.{byname,byuid} maps. If _pw_breakout_yp()
sees that the adjunct map was found and the password from the standard
maps starts with ##, it will try to grab the correct password field
from the adjunct map. As with the master.passwd maps, this only happens
if the caller is root, so the shadowing feature is preserved; non-root
users just get back ##username as the encrypted password.
Note that all we do is grab the second field from the passwd.adjunct.byname
entry, which is designated to be the real encrypted password. There are
other auditing fields in the entry but they aren't of much use to us.
Also switched back to using yp_order() to probe for the maps (instead
of yp_first()). The original problem with yp_order() was that it barfed
with NIS+ servers in YP compat mode since they don't support the
YPPROC_ORDER procedure. This condition is handled a bit more gracefully
in yplib now: we can detect the error and just punt on the probing.
Since locale reading code not resistent against stack overflowing or
similar intruder attacks, don't allow PATH_LOCALE env variable action
for s-bit programs (non-standard locale path setting)
strdup() it to prevent unsetenv() or setenv() effects. Check its length to
not allow user to overflow internal locale buffer. Move PATH_LOCALE
handling code into one place.
POSIX: make better stub for LC_MONETARY & LC_NUMERIC, now it check
locale directory existance instead of refusing all non-C non-POSIX
locales. POSIX treats empty locale env variable as unset variable
while our old code treats it as "C" locale, fix it. Implement previous locale
restoring, if locale setting fails. Old code assumes success if some
of LC_ALL subset is successed even other fails, POSIX treats it as
failure with previous locale restoring, fix it.
Remove unneccessary length checking in currentlocale()
Garbage in `eacces' caused the wrong errno to be set for non-EACCES errors.
Garbage in `etxtbsy' caused a semi-random retry strategy for ETXTBSY errors.
Found by: NIST-PCTS. gcc -Wall reported the problem, but -Wall is not
enabled for libc.

Also added the MNT_RELOAD, MNT_WANTRDWR, MNT_ASYNC, MNT_NOATIME,
MOUNT_UNION flags. Someone might want to check my description of MNT_RELOAD.

- Add socket descriptor sanity checks to _yp_unbind().
- Fix yp_order() so that it handles the RPC_PROCUNAVAIL error gracefully.
NIS+ in YP compat mode doesn't support the YPPROC_ORDER procedure.
This is a 2.2 candidate with bells on.

Use 'char' function argument for proper sign extension
Add progname to warning/error message layout. (joerg)

Remove on the fly calculation of parameters, no longer critical.
Make D & U flags valid even if we don't support them.

Zap contents on free() if we have "Junk" set. [*]
Various nitpicking.

Somehow, I also managed to get quite some other changes in this file at
the same time. All I did was checkout the file and made a single change.
If someone has an explanation how these PURIFFY defines got in...
- removed references to nonexistent pathconf-related variables.
- document everything in CTL_MACHDEP(more than in sysctl.8) and
80% of the things in CTL_KERN (same as in sysctl.8).
