- getpwent:
o adjunctbuf should be NUL terminated after copying
o _pw_breakout_yp() needs to know the length of the buffer returned
from YP so it can properly NUL terminate its local buffer.
- getgrent:
o YP buffers should be YPMAXRECORD + 2 bytes long and NUL terminated.
(Previously they were hardcoded to 1024 bytes.)
- getnetgrent:
o YP data should be copied with snprintf(), not sprintf()
These are 2.2 candidates. I will wait a few days to make sure these don't
break anything and then, if there are no objections, move them to the 2.2
branch.
- getservent:
o put _yp_check() proto under #ifdef YP where it belongs
o local YP buffers should be YPMAXRECORD + 2 bytes long and should
be NUL terminated after copying
- gethostbynis:
o local YP buffer should be YPMAXRECORD + 2 bytes long
- getnetbynis:
o local YP buffer should be YPMAXRECORD + 2 bytes long and should
be NUL terminated after copying
- ether_addr:
o local YP buffers should be YPMAXRECORD + 2 bytes long and should
be NUL terminated after copying (in this case it's BUFSIZ + 2 bytes,
but it happens that BUFSIZ == YPMAXRECORD.
- gethostbydns:
o nuke stray 'return(NULL)' in __dns_getanswer() (harmless but looks silly)
These are 2.2 candidates. I will wait a few days to make sure these don't

able to be exploited, or might not. However, it is better to be safe
than sorry.
Definitely a 2.2 fix, and a -stable if there is someone to commit it.

Remove a duplicate entry for ahc0 in hardware.hlp (closes PR #
docs/2282), a few additions all over the place while i was at it.
Tried to add as much of the important highlights for the new features
in 2.2 into the release notes. I still think that many things are
missing here, so folks, if you imported something great that's in 2.2
but not in 2.1.X, please review this section and send us your
additions!

line length limit anymore - now 500 members or 5000 members are
possible. For security group lines longer than 256K will be count as
an error. 256K should be enough for 65536 users.
Support comments (lines that begin with a #) if compiled with

Fortunately it seems that all system utilities which use getgrent()
functions are dynamically linked executables. So you need only
rebuild libc.so.3.0 if you want this change. Note: if you have
an old X server which depend on libc.so.2.* you should rebuild
libc.so.2.* too.
Not a 2.2 candidate.
successful write. Only do it for the IO_SYNC case (like ufs). On
one of my systems, this speeds up `iozone 24 512' from 32K/sec
(1/128 as fast as ufs) to 2.8MB/sec (7/10 as fast as ufs).

Generalize the selection of programs to run based on the existance of files
rather than the OS names that we find. Add comments about me being the
keeper of the OpenBSD mods of this file. Use ftp on OpenBSD rather than
fetch since OpenBSD's FTP supports urls and there is no fetch.

- yp_main.c: Always add the resolver socket to the set of fds
monitored by select(). It can happen that pending == 0 but we
still have some data in the socket buffer from an old query.
This way, the data will be flushed in a timely manner.
- yp_extern.h: remove proto for yp_dns_pending() since we don't need
it anynmore.
- yp_server.c: call yp_async_lookup_name()/yp_async_lookup_addr()
functions with the svc_req pointer as an arg instead of the xprt.
(The svc_req struct includes a pointer to the transport handle,
and it also has the service version number which the async DNS
code will need. (see below))
- yp_dnslookup.c:
o Nuke yp_dns_pending() since we don't need it anymore.
o In yp_run_dnsq(), swallow up and ignore replies if no requests
are pending or the ID doesn't match any of the IDs in the queue.
o In yp_send_dns_reply(), we assume that we will always be
replying to an NIS v2 client. While this will probably always
be the case, we do support the v1 'match' procedure, and it
has a different result struct than v2. For completeness,
support replying to both NIS v1 and v2 clients.
o Update the queue entry structure to include a member to
keep track of the NIS version number.
o Have yp_async_lookup_name/addr() extract the version number
from the svc_req structure and save it with the queue entry
for yp_send_dns_reply() to inspect later.
o Add some comments.
while remaining (becoming :) compatible with other popular shells.
Specifically these changes include:
1) Implement 'trap -l' to get a list of valid signals names. This
is useful if you wanted to do something like reset all signal
handlers to there defaults values, in which case something like
this will do the trick.
trap `trap -l`
2) Reformat the output of 'trap' so it can be saved and later eval'd
to restore the saved settings.
3) Allow the use of signal names as well as signal numbers.
4) Fix trap handling of SIGCHLD so that commands like the following
(albeit, contrived) won't cause sh(1) to recurse ad infinitum.
trap uname 0 20
5) Make variables static that are used only in trap.c.
6) Minor 'style(9) police' mods.
