- bzipfs and gzipfs now properly return errno values directly from their
read routines rather than returning -1.
- missing errno values on error returns for the seek routines on almost
all filesystems were added.
- fstat() now returns -1 if an error occurs rather than ignoring it.
- nfs's readdir() routine now reports valid errno values if an error or
EOF occurs rather than EPERM (It was just returning 0 for success and
1 for failure).
- nullfs used the wrong semantics for every function besides close() and
seek(). Getting it right for close() appears to be an accident at that.
- read() for buffered files no longer returns 0 (EOF) if an error occurs,
but returns -1 instead.

This results in no functional change, aside from fixing a data
corruption bug on LP64 platforms. The code here could still use a
significant amount of cleanup.

a list in the thread structure to keep track of the locks and
how many times they have been locked. This list is checked
on every lock and unlock. The traversal through the list is
O(n). Most applications don't hold so many locks at once that
this will become a problem. However, if it does become a problem
it might be a good idea to review this once libthr is
off probation and in the optimization cycle.
This fixes:
o deadlock when a thread tries to recursively acquire a
read lock when a writer is waiting on the lock.
o a thread could previously successfully unlock a lock it did not own
o deadlock when a thread tries to acquire a write lock on
a lock it already owns for reading or writing [ this is admittedly
not required by POSIX, but is nice to have ]
- Update and improve the documentation for %[aA]
o Like %[eE], %[aA] may round the result if a precision is specified.
o Grammar police: Fix a split infinitive.
o The FreeBSD implementation does better than the minimum required
by C99 (literal translation of the mantissa). The digit before
the hexadecimal-point is never 0 unless the number itself is 0.
o Clarify that the exponent field represents a decimal exponent of 2.
o Discuss the fact that multiple valid representations are possible.
o Remove the entry in the BUGS section claiming that %[aA] is not
implemented.
- Remove the entry in the BUGS section claiming that the ' flag for
printing thousands separators is unimplemented for floating-point.
- Remove the entry in the BUGS section claiming that the L modifier

on the release media -- only put what is different in the crypto
version compared to the base version. This reduces PAM entries
in /usr/lib in the "crypto" distribution to:
libpam.a
libpam.so@
libpam.so.2
pam_krb5.so@
pam_krb5.so.2
pam_ksu.so@
pam_ksu.so.2
pam_ssh.so@
pam_ssh.so.2
The libpam.so* is still redundant (it is identical to the "base"
version), but we can't set DISTRIBUTION differently for libpam.a
and libpam.so.
(The removal of libpam.so* from the crypto distribution could be
addressed by the release/scripts/crypto-make.sh script, but then
we'd also need to remove redundant PAM headers, and I'm not sure
this is worth a hassle.)
these are not fully implemented and ifdef'd out, the bugs have
never manifested themselves. Specifically:
- Fix a memory leak in the case where %a follows another
floating-point format.
- Make the %a/%A code behave like %e/%E with respect to
precision.
- It is no longer valid to assume that '-' and '0x' are
mutually exclusive.
- Address other minor issues.

o Refactor the pthread_rwlock_[try]rdlock() and pthread_rwlock_[try]wrlock()
functions. They are now completeley condensed into rwlock_rdlock_common()
and rwlock_wrlock_common(), respectively.
o If the application tries to destroy an rwlock that is currently
held by a thread return EBUSY where it previously went ahead and
freed all resources associated with the lock.
o Refactor _pthread_rwlock_init() to make it look (relatively) sane.
o When obtaining a read lock on an rwlock the check for whether it
would exceed the maximum allowed read locks should happen *before*
we obtain the lock.
o The pthread_rwlock_* functions shall *never* return EINTR, so make
sure to requeue/resuspend the thread if it encounters such an error.
o Make a note that pthread_rwlock_unlock() needs to ensure it holds a
lock on an rwlock it tries to unlock. It will be implemented in a
separate commit because it requires some additional rwlock infrastructure.

getpwent(3) or getpwuid(3) when using NIS adjunct maps. The bug was
present in the internal `nis_passwd' function. The lookup in the
adjunct map used the name passed into `nis_passwd', however no name
was of course supplied by getpwent or getpwuid. Correctly use the
name from the `struct pwd' that was found instead.
