- Fix problem described in PR #1079: _gethostbynisaddr() doesn't
work. Make it accept the same arguments as all the other
gethostby*addr() functions and properly convert the supplied IP
address into a text string so that yp_match() can find it in the
hosts.byaddr map.
- Also fix potential memory leak: copy the results of yp_match() to
a static buffer and free the result (yp_match() returns dynamically
allocated memory).
ether_addr.c:
- Since I was in the neighborhood, fix ether_ntohost() and
ether_hostton() so that they don't bogusly for a free(result)
when yp_match() fails.
matter much on some systems, but on ftp servers (like wcarchive) where
you run with special stripped group and pwd.db files in the anonymous
ftp /etc, this can be a major speedup for ls(1).
ss_flags to SS_DISABLE and SS_ONSTACK. SA_ONSTACK is still used in
struct sigaction. Nowhere in our entire source tree could I find a
single place these were used.
reconnect once using the saved openlog() parameters.
This helps one of the system startup race conditions. If syslogd takes too
long to get going, some daemons can fail the connection and forever log
to the console even though the syslogd is running. That is ..unfortunate..
the statically compiled PS_STRINGS and USRSTACK variables. This prevents
programs using setproctitle from coredumping if the kernel VM is increased,
and stops libkvm users (w, ps, etc) from needing to be recompiled if only
the VM layout changes.
explicit that it is global to the entire "session", and that setsid() or
daemon() are need to have been called at some point.
The most notable offender of setlogin() misuse is XFree86's xdm.
for "fts_open" was wrong. Also, the "fts_info" field of the FTSENT
structure was misleadingly described as containing "flags". Actually, it
contains a single integer value.
in the main text of various man pages.
Thanks to Warner Losh for adding an option to manck to allow
it to scan the entire man page looking for bogus xrefs, instead
of just checking the SEE ALSO section.
resides in read-only memory is going to cause the program to core dump,
and this is commmon with older pre-ANSI C programs.
(I've scratched my head over this one at 3 in the morning before
while trying to port some ancient program)

Also corrected a few minor formatting errors, file location and cross
references in some of the section 3 man pages.
This shuts up a lot of the output from "manck" for section 3.
Install (optional) libutil.h with prototypes for the functions and
document this in the man page.
minor cleanups to the various routines, include the prototype file, declare
return codes etc.
of signals. Signals are now properly caught, tty state is being
restored, and the previous sigaction triggered. Upon receipt of a
sigcont, echo is turned off again.
SIGTSTP causes a buffer flush, the man page mentions this. (Although
i rather think of it as a feature than a bug.)
This is likely to be my last FreeBSD action for 1995, xearth shows
me that our .au guys must already write 1996. :-)
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches. The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.
gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes. Does anyone
disagree?
gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header. This
hack will do until then. (Use gprof4 -u to examine the results
of non-statistical profiling.)
config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.
kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'. `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.
is really necessary. Going backwards on a P6 is much slower than forwards
and it's a little slower on a P5. Also moved the count mask and 'std'
down a few lines - it's a couple percent faster this way on a P5.
replace the dozen other various hacks in the code that do all sorts
of crude things including spamming the envrionment strings with the new
argv string.
This version is mainly inspired by the sendmail version, with a couple of
ideas taken from the NetBSD implementation as well.
XDR routines auto-generated by rpcgen don't quite match the format of
the original ones even though tey have the same names (that was one of
the things wrong with the old XDR routines).
rpcgen-erated on the fly (just like librpcsvc).
Makefile: Add rule for generating yp_xdr.c and yp.h.
xdryp.c: gut everything except the special ypresp_all XDR function
needed to to handle yp_all() (this one can't be created on
the fly), and xdr_datum(), which isn't used internally by
libc, but which as documented as being there in yp_prot.h,
so what the hell. We now get everything else from yp_xdr.c.
yplib.c: change a few structure member names to match those found in
yp.h instead of those declared in yp_prot.h.
via mmap() up around the shared library area. Previously the directory
was allocated from space from it's own memory pool. Because of the way it
was being extended on processes with large malloced data segments (ie: inn)
once the page directory was extended for some reason, it was not possible
to lower the heap size any more to return pages to the OS.
(If my understanding is correct, page directory expansion occurs at 4MB,
12MB, 20MB, 28MB, etc.) I was seeing INN allocate a large amount of short
term memory, pushing it over the 28MB mark, and once it's transient demands
hit 28MB, it never freed it's pages and swap space again.)
I've been running this in my libc for about a month...
Also, seperate MALLOC_STATS from EXTRA_SANITY.. I found it useful to call
malloc_dump() from within INN from a ctlinnd command to see where the hell
all the memory was going.. :-) I've left MALLOC_STATS enabled, as it has
no run-time or data storage cost.

it before before trying to establish a binding. If /var/run/ypbind.lock
doesn't exist, or if it exists and isn't locked, then ypbind isn't
running, which means NIS is either turned off or hosed.
- Have _yp_check() call yp_unbind() after it sucessfully calls yp_bind()
to make sure it frees resources correctly. (I don't think there's really
a memory leak here, but it seems somehow wrong to call yp_bind() without
making a corresponding call to yp_unbind() afterwards.)
This makes the NIS code behave a little better in cases where libc makes
calls to NIS, but it isn't running correctly (i.e. there's no ypbind).
This cleans up some strange libc behavior that manifests itself if
you have the system domain name set, but aren't actually running NIS.
In this event, the getrpcent(3) code could try to call into NIS and
cause several inexplicable "clnttcp_create error: RPC program not
registered" messages to appear. This happens because _yp_check() checks
if the system domain name is set and, if it is, proceeds to call
yp_bind() to attempt to establish a binding. Since there is no
binding file (remember: ypbind isn't running, so /var/yp/binding
will be empty), _yp_dobind() will attempt to contact ypbind to
prod it into binding the domain. And because ypbind isn't running,
the code generates the 'clnttcp_create' error. Ultimately the
_yp_check() fails and the getrpcent(3) code rolls over to the /etc/rpc
file, but the error messages are annoying, and the code should be
smart enough to forgo the binding attempt when NIS is turned off.
both call getservent() to do most of the work, so we only need to modify
this file to take care of everybody).
Note that there is only one NIS services map (services.byname) even
though there are getservbyname() and getservbyport() library functions.

I still belive the quad stuff should go back into gcc.
Add compile-time warnings about crypt functions.
