      [SNAP] make SNAP work again · 0cf604b1
      Arnaldo Carvalho de Melo authored
      Stupid me, this is really needed, IPX as it supports several datalink_protos
      and needs pt->type to find the right interface. Appletalk doesn't care, so
      it worked without this. And these are the only snap users in the kernel.

      SCTP: Resync with LKSCTP tree. · 372f525b
      Jon Grimm authored
      sctp: one more list_t removal.
      sctp: more whitespace cleanup (jgrimm)
      sctp: merge with linux bk tree
      sctp: Minor ABORT updates (ardelle.fan)  
      sctp: Fix misc. COOKIE-ECHO bundling bugs.  (jgrimm)
      
        There were small windows where the following could occur.
        -Two DATA chunks bundled with COOKIE-ECHO (only 1 allowed.)
        -DATA bundled with lost COOKIE-ECHO needs resent too.
        -DATA sent while in COOKIE-ECHOED if there had not been control data already bundled.
      
      sctp:  more updates for abort (jgrimm and ardelle.fan)
        
        Cleanup T5 upon abort.   Send COMM_LOST notification to ULP upon abort.
      
      sctp: updates to T5 shutdown timer.  (samudrala)
        
        I missed a couple changes from Sridhar's last patch.
      
      sctp: more ABORT, cleanup shutdown timers (ardelle.fan)
        
        When we send or receive an ABORT, there may be a variety of timers running. 
        Turn these timers off when we abort.
      
      sctp: Fix bug in COOKIE-ECHO retransmission.  (jgrimm)
          
        We had saved away the pointer directly to the INIT-ACK state cookie param, but upon COOKIE ECHO retransmission, this skb has already been thrown away.   The fix is to save away the cookie.
      
      sctp:  Unknown chunk processing. (daisyc)
        
        Each chunkheader contains the chunk type.  
        For forward compatiblity, 'action' bits in the type describe what action 
        the peer requests if one does not understand that chunk type.  This patch is to
        implement the handling of those 'unrecognized chunk' actions.
      
      sctp: Add T5 shutdown guard handling. (samudrala)
        
        The T5-shutdown-guard timer is used to bound the time we are willing to try gracefully shutting down.   This protects against certain pathological peers.
      
      sctp: Add msg_name support for notifications and PF_INET sockets. (jgrimm)

      [PATCH] exit-fix-2.5.38-E3 · 5dd6a6e5
      Ingo Molnar authored
      This fixes a number of bugs in the thread-release code:
      
       - notify parents only if the group leader is a zombie,
         and if it's not a detached thread.
      
       - do not reparent children to zombie tasks.
      
       - introduce the TASK_DEAD state for tasks, to serialize the task-release
         path. (to some it might be confusing that tasks are zombies first, then
         dead :-)
      
       - simplify tasklist_lock usage in release_task().
      
      the effect of the above bugs ranged from unkillable hung zombies to kernel
      crashes. None of those happens with the patch applied.

      [PATCH] ALi and Cypress IDE fixes · 26b90050
      Ivan Kokshaysky authored
      These two chipsets are most common on alpha.
      - cy82c693: allow the generic IDE setup code to work correctly
        with broken PCI registers layout of this chip. This fixes
        quite a few problems with secondary channel, plus some hacks in
        arch code can go away.

      [PATCH] pidhash-2.5.38-A0 · 5191a147
      Ingo Molnar authored
      This removes the cmpxchg from the PID allocator and replaces it with a
      spinlock.  This spinlock is hit only a couple of times per bootup, so
      it's not a performance issue.

      [PATCH] thread-flock-2.5.38-A3 · a16435af
      Ingo Molnar authored
      Ulrich found another small detail wrt. POSIX requirements for threads -
      this time it's the recursion features (read-held lock being write-locked
      means an upgrade if the same 'process' is the owner, means a deadlock if a
      different 'process').
      
      this requirement even makes some sense - the group of threads who own a
      lock really own all rights to the lock as well.
      
      These changes fix this, all testcases pass now.  (inter-process
      testcases as well, which are not affected by this patch.)
      
      (SIGURG and SIGIO semantics should also continue to work - there's some
      more stuff we can optimize with the new pidhash in this area, but that's
      for later.)

      [PATCH] loop device broken in 2.5.38 · 86b18ae3
      Theodore Y. Ts'o authored
      The loop device driver was broken in 2.5.38 when it was converted over
      to use gendisk.  I discovered this while doing final regression testing
      on the ext3 htree code.
      
      The problem is that figure_loop_size() is setting the capacity of the
      loop device in kilobytes (because that's what compute_loop_size()
      returns), but set_capacity() expects the size in 512 byte sectors.
      
      I've enclosed a patch which fixes the problem, as well as simplifying
      the code by eliminating compute_loop_size(), since it is a static
      function is only used once by figure_loop_size().

      [LLC] keep the skb in llc_sap_state_process · 0284d996
      Arnaldo Carvalho de Melo authored
      We have to hold the skb, because llc_sap_next_state
      will kfree it in the sending path and we need to
      look at the skb->cb, where we encode llc_sap_state_ev.

      [LLC] use struct sock list members · 97ef8f8c
      Arnaldo Carvalho de Melo authored
      Now that we don't have anymore the double sock (PF_LLC + core) we can
      use struct sock list members.
      
      Also use use rw locks instead of spinlocks in some places.

      [PATCH] fix null dereference in sys_mprotect · 0cd9efe3
      Paul Mackerras authored
      As it is at the moment, sys_mprotect will dereference a null pointer
      if you use it on a region that is contained within the first vma.  I
      have a little program that demonstrates this (I'll post it if anyone
      is interested).  What happens then is that the process hangs in
      do_page_fault at the down_read on the mm->mmap_sem, since sys_mprotect
      has done a down_write on mm->mmap_sem.
      
      The problem is that mprotect_fixup isn't updating prev properly.  Thus
      we can finish the main loop in sys_mprotect with prev == NULL.  This
      has been the case since Christoph's cleanups went in.  Prior to that,
      mprotect_fixup always set prev to something non-NULL.  I suspect that
      not updating prev could also cause vmas to get dropped completely if
      the region being mprotected spans more than one vma.
      
      The patch below fixes the problem by making mprotect_fixup set prev to
      a reasonable value in all circumstances.

      [PATCH] remove preempt workaround in slab.c · 7f644d00
      Robert Love authored
      Before the irqs_disabled() check in preempt_schedule(), we worked around
      some locking issues in slab.c.  Now that we will never preempt with
      interrupts disabled, we can remove those and clean things up.

      [PATCH] s/preempt_count()/in_atomic() in do_exit() · 5d671309
      Robert Love authored
      This converts the debugging check in do_exit from a check on
      preempt_count() to in_atomic().
      
      The main benefit to this is we will stop warning over the BKL and now
      use the standard mechanism for such checks.

      [PATCH] pgrp-fix-2.5.38-A2 · 872aa4a8
      Ingo Molnar authored
      This fixes the emacs bug reported by Andries.  It should probably also
      fix other, terminal handling related weirdnesses introduced by the new
      PID handling code in 2.5.38.
      
      The bug was in the session_of_pgrp() function, if no proper session is
      found in the process group then we must take the session ID from the
      process that has pgrp PID (which does not necesserily have to be part of
      the pgrp).  The fallback code is only triggered when no process in the
      process group has a valid session - besides being faster, this also
      matches the old implementation.
