775a76844f Catch up with many years of changes:
o Document PF_LOCAL as being an alias for PF_UNIX
o Document POSIX standardization of this interface using AF_*
  constants rather than PF_* constants, and note the three particular
  families which POSIX standardizes.
o Note anticipated POSIX standardization of SOCK_CLOEXEC.
o Delete from listing protocol families that FreeBSD doesn't support
  (in some cases, like PF_PUP, has never supported).
o Add to listing some current protocol families that have been
  introduced in the last decade or so.
o Document the correspondence of PF_* and AF_* constants.

We should probably change the documentation to make the AF_* constants
primary, but this commit does not do so.

f56cfe8d61 Fix table alignment. EVFILT_PROCDESC is longer than the existing filters. 2014-04-07 18:17:31 +00:00
Ed Schouten
38219d6acd Implement kqueue(2) for procdesc(4).
kqueue(2) already supports EVFILT_PROC. Add an EVFILT_PROCDESC that
behaves the same, but operates on a procdesc(4) instead. Only implement
NOTE_EXIT for now. The nice thing about NOTE_EXIT is that it also
returns the exit status of the process, meaning that we can now obtain
this value, even if pdwait4(2) is still unimplemented.

Notes:

- Simply reuse EVFILT_NETDEV for EVFILT_PROCDESC. As both of these will
  be used on totally different descriptor types, this should not clash.

- Let procdesc_kqops_event() reuse the same structure as filt_proc().
  The only difference is that procdesc_kqops_event() should also be able
  to deal with the case where the process was already terminated after
  registration. Simply test this when hint == 0.

- Fix some style(9) issues in filt_proc() to keep it consistent with the
  newly added procdesc_kqops_event().

- Save the exit status of the process in pd->pd_xstat, as we cannot pick
  up the proctree_lock from within procdesc_kqops_event().

2ad6bba714 Correct return type of pdfork(2).
The pdfork(2) man page states:

	"pdfork() returns a PID, 0 or -1, as fork(2) does."

As it returns a PID, the return type should obviously be pid_t. As int
and pid_t have the same size on all architectures, this change does not
affect the ABI in any way.

8876613dc5 Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP}
if not already defined. This allows building libc from outside of
lib/libc using a reach-over makefile.

A typical use-case is to build a standard ILP32 version and a COMPAT32
version in a single iteration by building the COMPAT32 version using a
reach-over makefile.
