      rt2x00: LEDS build failure · 6847aa5c
      由 Randy Dunlap 提交于 
      Config symbols that select LEDS_CLASS need to depend on NEW_LEDS so that
undefined symbols are not used in the build.

The alternative is to select NEW_LEDS, which some drivers do.

This patch fixes the led_* symbols build errors.

      b43: Fix possible NULL pointer dereference in DMA code · 028118a5
      由 Michael Buesch 提交于 
      This fixes a possible NULL pointer dereference in an error path of the
DMA allocation error checking code. This is also necessary for a future
DMA API change that is on its way into the mainline kernel that adds
an additional dev parameter to dma_mapping_error().

This patch moves the whole struct b43_dmaring struct initialization
right before any DMA allocation operation.

      rt2x00: Restrict DMA to 32-bit addresses. · 051c256f
      由 Gertjan van Wingerde 提交于 
      None of the rt2x00 PCI devices support 64-bit DMA addresses (they all
only accept 32-bit buffer addresses). Hence it makes no sense to try to
enable 64-bit DMA addresses. Only try to enable 32-bit DMA addresses.

      tcp: Revert 'process defer accept as established' changes. · ec0a1966
      由 David S. Miller 提交于 
      This reverts two changesets, ec3c0982
("[TCP]: TCP_DEFER_ACCEPT updates - process as established") and
the follow-on bug fix 9ae27e0a
("tcp: Fix slab corruption with ipv6 and tcp6fuzz").

This change causes several problems, first reported by Ingo Molnar
as a distcc-over-loopback regression where connections were getting
stuck.

Ilpo Järvinen first spotted the locking problems.  The new function
added by this code, tcp_defer_accept_check(), only has the
child socket locked, yet it is modifying state of the parent
listening socket.

Fixing that is non-trivial at best, because we can't simply just grab
the parent listening socket lock at this point, because it would
create an ABBA deadlock.  The normal ordering is parent listening
socket --> child socket, but this code path would require the
reverse lock ordering.

Next is a problem noticed by Vitaliy Gusev, he noted:

----------------------------------------
>--- a/net/ipv4/tcp_timer.c
>+++ b/net/ipv4/tcp_timer.c
>@@ -481,6 +481,11 @@ static void tcp_keepalive_timer (unsigned long data)
> 		goto death;
> 	}
>
>+	if (tp->defer_tcp_accept.request && sk->sk_state == TCP_ESTABLISHED) {
>+		tcp_send_active_reset(sk, GFP_ATOMIC);
>+		goto death;

Here socket sk is not attached to listening socket's request queue. tcp_done()
will not call inet_csk_destroy_sock() (and tcp_v4_destroy_sock() which should
release this sk) as socket is not DEAD. Therefore socket sk will be lost for
freeing.
----------------------------------------

Finally, Alexey Kuznetsov argues that there might not even be any
real value or advantage to these new semantics even if we fix all
of the bugs:

----------------------------------------
Hiding from accept() sockets with only out-of-order data only
is the only thing which is impossible with old approach. Is this really
so valuable? My opinion: no, this is nothing but a new loophole
to consume memory without control.
----------------------------------------

So revert this thing for now.

      ipv6: Fix duplicate initialization of rawv6_prot.destroy · f23d60de
      由 David S. Miller 提交于 
      In changeset 22dd4850
("raw: Raw socket leak.") code was added so that we
flush pending frames on raw sockets to avoid leaks.

The ipv4 part was fine, but the ipv6 part was not
done correctly.  Unlike the ipv4 side, the ipv6 code
already has a .destroy method for rawv6_prot.

So now there were two assignments to this member, and
what the compiler does is use the last one, effectively
making the ipv6 parts of that changeset a NOP.

Fix this by removing the:

	.destroy	   = inet6_destroy_sock,

line, and adding an inet6_destroy_sock() call to the
end of raw6_destroy().

Noticed by Al Viro.
