Remove empty file remnants that were left in the tree by mistake

Noted by various people (Sam, Jeff, Roland..)

Commit 58b7983d15a422d9616bdc4e245d5c31dfaefbe2 intended to remove the
xfs "Makefile-linux-2.6" file, but it was mistakenly still left in the
tree as a empty file, and would cause git to correctly complain about a
tracked file being removed after a "make distclean" (which removes empty
files as garbage).

And the asm-x86/desc_64.h file was supposed to be removed by commit
c81c6ca45a69478c7877b729af1942d2b80ef582, but instead stayed around
containing just a single newline.

Commit efcd9971 ("IPoIB/cm: Factor out ipoib_cm_free_rx_reap_list()")
introduced a bug in ipoib_cm_dev_stop() when the receive drain times
out.  In that case, the function moves all the pending rx stuff into a
private list but then calls ipoib_cm_free_rx_reap_list(), which
handles a different list.

Fix this by moving everything to the rx_reap_list that will actually
get freed up.

11 years agoRevert "SLUB: Alternate fast paths using cmpxchg_local"
Linus Torvalds [Tue, 19 Feb 2008 17:08:49 +0000]
Revert "SLUB: Alternate fast paths using cmpxchg_local"

This reverts commit 1f84260c8ce3b1ce26d4c1d6dedc2f33a3a29c0c, which is
suspected to be the reason for some very occasional and hard-to-trigger
crashes that usually look related to memory allocation (mostly reported
in networking, but since that's generally the most common source of
shortlived allocations - and allocations in interrupt contexts - that in
itself is not a big clue).

See for example
http://bugzilla.kernel.org/show_bug.cgi?id=9973
http://lkml.org/lkml/2008/2/19/278
etc.

One promising suspicion for what the root cause of bug is (which also
explains why it's so hard to trigger in practice) came from Eric
Dumazet:

   "I wonder how SLUB_FASTPATH is supposed to work, since it is affected
    by a classical ABA problem of lockless algo.

    cmpxchg_local(&c->freelist, object, object[c->offset]) can succeed,
    while an interrupt came (on this cpu), and several allocations were
    done, and one free was performed at the end of this interruption, so
    'object' was recycled.

    c->freelist can then contain the previous value (object), but
    object[c->offset] was changed by IRQ.

    We then put back in freelist an already allocated object."

but another reason for the revert is simply that everybody agrees that
this code was the main suspect just by virtue of the pattern of oopses.

Ralf Baechle [Mon, 11 Feb 2008 14:51:40 +0000]
[MIPS] Handle I-cache coherency in flush_cache_range()

So far flush_cache_range() did't consider the I-cache largely because it
did rarely ever matter to real world code.  This was working primarily
because normally code and data are don't share the same pages - with the
exception of MIPS16 code which uses address constants embedded between
the code.   The following sequence of events may break the code:

 o MIPS16 executable being loaded
 o dynamic linker relocates the address constants embedded into the code:
 o   Uses mprotect(2) to make code pages PROT_READ|PROT_WRITE
 o   Performs the actual relocations by writing to the pages which likely
     are COW.  Because no PROT_EXEC is set I-cache coherence will not be
     considered.
 o   Uses mprotect(2) to switch code pages back to PROT_READ|PROT_EXEC.
     This results in a call to flush_cache_range() which also does not
     consider I-caches.
 o => executing the page just having been relocated may now result in the
   I-cache getting refilled with stale data from memory.

11 years agoSmack: unlabeled outgoing ambient packets
Casey Schaufler [Fri, 15 Feb 2008 23:24:25 +0000]
Smack: unlabeled outgoing ambient packets

Smack uses CIPSO labeling, but allows for unlabeled packets by
specifying an "ambient" label that is applied to incoming unlabeled
packets.

Because the other end of the connection may dislike IP options, and ssh
is one know application that behaves thus, it is prudent to respond in
kind.

This patch changes the network labeling behavior such that an outgoing
packet that would be given a CIPSO label that matches the ambient label
is left unlabeled.  An "unlbl" domain is added and the netlabel
defaulting mechanism invoked rather than assuming that everything is
CIPSO.  Locking has been added around changes to the ambient label as
the mechanisms used to do so are more involved.

x86: fix WARN_ON() message: teach page_is_ram() about the special 4Kb bios data page

This patch teaches page_is_ram() about the fact that the first
4Kb of memory are special on x86, even though the E820 table
normally doesn't exclude it.

This fixes the WARN_ON() reported by Laurent Riffard who was also
very helpful in diagnosing the issue.

11 years agox86, kprobes: remove sparse warnings from x86
Harvey Harrison [Thu, 14 Feb 2008 23:23:53 +0000]
x86, kprobes: remove sparse warnings from x86

arch/x86/kernel/kprobes.c:584:16: warning: symbol 'kretprobe_trampoline_holder' was not declared. Should it be static?
arch/x86/kernel/kprobes.c:676:6: warning: symbol 'trampoline_handler' was not declared. Should it be static?

Make them static and add the __used attribute, approach taken from the
arm kprobes implementation.

kretprobe_trampoline_holder uses inline assemly to define the global
symbol kretprobe_trampoline, but nothing ever calls the holder explicitly.

trampoline handler is only called from inline assembly in the same file,
mark it used and static.
