Added documentation that inetd can open UNIX-domain sockets. It's been
able to do this for over a decade but it hasn't been documented and it's
quite a nice feature.
support for specifying an accept filter for a service (mostly as a usage
example, but it can be handy for other things). Manual pages to follow
in a day or so.
OK core@.
legacy code), if the builtin service forks (not all do), avoid leaking
listening sockets into the child process.
If the child process were to keep copies of the listening sockets
around and then hang about for a long time, it would prevent inetd
from being able to re-bind them upon restart.
The listening sockets are tagged close-on-exec, but that doesn't help
when one doesn't exec.
Patch from my own very old PR 8253.
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry. RedHat has
evidently built all "core system packages" with this option for some time.
This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.
This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros. Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.
Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.
* Remove a few trailing whitespaces
* Rearrange and join to one #if for some headers

last 60 second interval is reached to more accurately reflect
what has happened.
Also, break up a few long strings, obey 80 columns, and remove a
superfluous newline passed to syslog(3).
- Don't invoke kevent(2) for every single event change. Instead collect
event changes and try to do them in the event loop.
- Handle signals via kevent(2) to avoid race conditions for SIGHUP (which
probably exist in the select(2) based implementation, too).
