MFC rev 1.20 to 1.23 access.2

2008-02-14T21:45:41+00:00

  v1.23
  After issueing a ntpdate [1] I noticed it's already 2008, reflect that
  in the last modified date.

  Noticed by:	brueffer [1]

  v1.22
  Fix typo (s/existance/existence/)

  Noticed by:	ceri

  v1.21
  Fix some style nits.

  Prodded by:	brueffer
  MFC After:	3 days

  v1.20
  Make the warning a bit less 'broad' then it used to be.  The access
  is seems to be a problem for SUID applications, which we like to
  prevent as much as possible.

Change the C wrappers for mmap/lseek/pread/pwrite/truncate/ftruncate to

2007-07-04T23:27:38+00:00

call the pad-less versions of the corresponding syscalls if the running
kernel supports it.  Check kern.osreldate once per program and cache the
result to select the appropriate syscall.  This maintains userland
compatability with kernel.old's from quite a while back.

Classify mmap, lseek, pread, pwrite, truncate, ftruncate as pseudo

2007-07-04T23:23:01+00:00

syscalls, unless WITHOUT_SYSCALL_COMPAT is defined.  The default case
will have the .c wrappers still.  If you define WITHOUT_SYSCALL_COMPAT,
the .c wrappers will go away and libc will make direct syscalls.

After 7-stable starts, the direct syscall method will be default.
