asked to verify a passwd file (pwd_mkdb -C).
Entries with oversized usernames are still permitted when building
the passwd database.
When entries are >= MAXLOGNAME in length, they are correctly stored
in passwd, pwd.db and spwd.db but are only correctly retrieved by
getpwent*() and getpwuid*(). getpwnam*() truncates to MAXLOGNAME - 1
when reading from a file (breaking at least sh, tcsh and bash)
and utilities such as su(1) check, complain and fail if the
passed name is >= MAXLOGNAME in length.

avoid the confusing error message about the line being too long). This
change uses fgetln to detect the right conditions, but the fixed-width
line buffer is kept because too many other places in the program make
assumptions about its maximum width.

While version 4 entries are architecture-independent, we
also store old (version 3) entries in native byte order.
Also, the hash itself is created in a native byte order.
With this change, pwd_mkdb(8) can be used to cross-build
*pwd.db files for another architecture.

you've specified a directory. It is intended to be used in building
custom releases over NFS where locking may be unreliable at best and
there is no contention that the locking is designed to arbitrate.
Other uses of this flag are discouraged. Document same in usage and
man page (including the warning about unwise).

(1) use strlcpy instead of strncpy since the use here of the latter
was incorrect.
(2) Move 'N' case into proper sorted order (sorted the same way that
ls sorts its args).
do not add the "\xFF" "VERSION" key --- it should only be added once
ALL entries have been updated.
While I'm here, correct the logic that detects whether or not the
user-ID has changed so that it works even if all entries have not
yet been updated to the new format.

family of functions using the new nsdispatch(3) core. Remove
arbitrary size limits when using the thread-safe versions.
= Re-implement the traditional getpwent(3)/getgrent(3) functions on
top of the thread-safe versions.
= Update the on-disk format of the hashed version of the passwd(5)
databases to allow for versioned entries. The legacy version is
`3'. (Don't ask.)
= Add support for version `4' entries in the passwd(5) database.
Entries in this format are identical to version 3 entries except
that all integers are stored as 32-bit integers in network byte
order (big endian).
= pwd_mkdb is updated to generate both version 3 and version 4
entries.

tweaks here. We can define a record format that uses 64 bit times if/when
we need to.
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.
= Hesiod has been added to libc (see hesiod(3)).
= A library routine for parsing nsswitch.conf and invoking callback
functions as specified has been added to libc (see nsdispatch(3)).
= The following C library functions have been modified to use nsdispatch:
. getgrent, getgrnam, getgrgid
. getpwent, getpwnam, getpwuid
. getusershell
. getaddrinfo
. gethostbyname, gethostbyname2, gethostbyaddr
. getnetbyname, getnetbyaddr
. getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr
= host.conf has been removed from src/etc. rc.network has been modified
to warn that host.conf is no longer used at boot time. In addition, if
there is a host.conf but no nsswitch.conf, the latter is created at boot
time from the former.

the environment. This allows big ID warnings to be suppressed for
vipw and chpass as well.
Since the environment variable test is only performed for callers
of pw_scan() that do not set pw_big_ids_warning, the test can still
be overriden. Currently, chpass and pwd_mkdb are the only users
of pw_scan() and neither of them overrides the environment variable
test.

Have pwd_mkdb lock the source file while rebuilding the database. When
called by programs such as vipw, the source file is a temporary file and
this does not conflict with the lock on /etc/master.passwd already held
by vipw. When run manually, however, master.passwd is typically specified
as the argument and the locking prevents other programs from messing with
master.passwd during the database rebuild.
Also pwd_mkdb uses a blocking exclusive lock as it may be called from
a script. The -N option was added to cause pwd_mkdb to get the lock
non-blocking and exit with an error if the attempt fails, again useful
for scripts.
