MFC Revision 197277:

2009-10-20T19:05:43+00:00

Make libc.a provide __stack_chk_fail_local weak alias. This is
needed to satisfy static libraries that are compiled with -fpic
and linked into static binary afterwards. Several libraries in
gcc are examples of such static libs.

2009-10-04T21:46:43+00:00

Correct the pthread stub prototype for pthread_mutexattr_settype to allow for
the type argument.  This is known to fix some pthread_mutexattr_settype()
invocations, especially when it comes to pulseaudio.

cr_groups is no longer embedded in struct ucred and is instead stored
in a seperate array.  As such we need to use kvm_read rather than bcopy
to populate the ki_groups field.

This fixes a crash when running ps -ax on a coredump.

  Revision: 197322
  Log:
    Correct BIOS header sanitizing on pc98.

  Revision: 197374
  Log:
    Disable a check on a disk size because it's too strict.  This change is
    to avoid using incorrect geometry.

   It seems that this is the same problem in g_part_bsd_read()@g_part_bsd.c.

Let fall down in the hard path (thus handling shared waiters wakeup
correctly) for the shared waiters also in the rwlock held in shared mode
as well, fixing possible deadlocks.

Please note that this is a special condition as we want this fix in
before RC2 as we assume it is critical and so it has been handled
as an instant-merge.  For the STABLE_7 branch, 1 week before the MFC
is assumed.

MFC r196962: Fix /usr/bin/unzip: A bug deep in libarchive's read-ahead logic

2009-09-17T06:31:59+00:00

(incorrect handling of zero-length reads before the copy buffer is
allocated) is masked by the iso9660 taster.  Tar and cpio both enable
that taster so were protected from the bug; unzip is susceptible.

This both fixes the bug and updates the test harness to exercise
this case.
