sctp: Fix ECN markings for IPv6

Commit e9df2e8fd8fbc95c57dbd1d33dada66c4627b44c ("[IPV6]: Use
appropriate sock tclass setting for routing lookup.") also changed the
way that ECN capable transports mark this capability in IPv6.  As a
result, SCTP was not marking ECN capablity because the traffic class
was never set.  This patch brings back the markings for IPv6 traffic.

sctp: Flush the queue only once during fast retransmit.

When fast retransmit is triggered by a sack, we should flush the queue
only once so that only 1 retransmit happens.  Also, since we could
potentially have non-fast-rtx chunks on the retransmit queue, we need

11 years agotcp: fix skb vs fack_count out-of-sync condition
Ilpo Järvinen [Wed, 4 Jun 2008 19:07:44 +0000]
tcp: fix skb vs fack_count out-of-sync condition

This bug is able to corrupt fackets_out in very rare cases.
In order for this to cause corruption:
  1) DSACK in the middle of previous SACK block must be generated.
  2) In order to take that particular branch, part or all of the
     DSACKed segment must already be SACKed so that we have that
     in cache in the first place.
  3) The new info must be top enough so that fackets_out will be
     updated on this iteration.
...then fack_count is updated while skb wasn't, then we walk again
that particular segment thus updating fack_count twice for
a single skb and finally that value is assigned to fackets_out
by tcp_sacktag_one.

It is safe to call tcp_sacktag_one just once for a segment (at
DSACK), no need to call again for plain SACK.

Potential problem of the miscount are limited to premature entry
to recovery and to inflated reordering metric (which could even
cancel each other out in the most the luckiest scenarios :-)).
Both are quite insignificant in worst case too and there exists
also code to reset them (fackets_out once sacked_out becomes zero
and reordering metric on RTO).

This has been reported by a number of people, because it occurred
quite rarely, it has been very evasive. Andy Furniss was able to
get it to occur couple of times so that a bit more info was
collected about the problem using a debug patch, though it still
required lot of checking around. Thanks also to others who have
tried to help here.

This is listed as Bugzilla #10346. The bug was introduced by
me in commit 68f8353b48 ([TCP]: Rewrite SACK block processing &
sack_recv_cache use), I probably thought back then that there's
need to scan that entry twice or didn't dare to make it go
through it just once there. Going through twice would have
required restoring fack_count after the walk but as noted above,
I chose to drop the additional walk step altogether here.

11 years agotcp: Fix inconsistency source (CA_Open only when !tcp_left_out(tp))
Ilpo Järvinen [Wed, 4 Jun 2008 18:34:22 +0000]
tcp: Fix inconsistency source (CA_Open only when !tcp_left_out(tp))

It is possible that this skip path causes TCP to end up into an
invalid state where ca_state was left to CA_Open while some
segments already came into sacked_out. If next valid ACK doesn't
contain new SACK information TCP fails to enter into
tcp_fastretrans_alert(). Thus at least high_seq is set
incorrectly to a too high seqno because some new data segments
could be sent in between (and also, limited transmit is not
being correctly invoked there). Reordering in both directions
can easily cause this situation to occur.

I guess we would want to use tcp_moderate_cwnd(tp) there as well
as it may be possible to use this to trigger oversized burst to
network by sending an old ACK with huge amount of SACK info, but
I'm a bit unsure about its effects (mainly to FlightSize), so to
be on the safe side I just currently fixed it minimally to keep
TCP's state consistent (obviously, such nasty ACKs have been
possible this far). Though it seems that FlightSize is already
underestimated by some amount, so probably on the long term we
might want to trigger recovery there too, if appropriate, to make
FlightSize calculation to resemble reality at the time when the
losses where discovered (but such change scares me too much now
and requires some more thinking anyway how to do that as it
likely involves some code shuffling).

This bug was found by Brian Vowell while running my TCP debug
patch to find cause of another TCP issue (fackets_out
miscount).

11 years agonet: neighbour table ABI problem
Stephen Hemminger [Tue, 3 Jun 2008 23:03:15 +0000]
net: neighbour table ABI problem

The neighbor table time of last use information is returned in the
incorrect unit. Kernel to user space ABI's need to use USER_HZ (or
milliseconds), otherwise the application has to try and discover the
real system HZ value which is problematic.  Linux has standardized on
keeping USER_HZ consistent (100hz) even when kernel is running
internally at some other value.

This change is small, but it breaks the ABI for older version of
iproute2 utilities.  But these utilities are already broken since they
are looking at the psched_hz values which are completely different. So
let's just go ahead and fix both kernel and user space. Older
utilities will just print wrong values.

ax25: Fix NULL pointer dereference and lockup.

From: Jarek Poplawski <jarkao2@gmail.com>

There is only one function in AX25 calling skb_append(), and it really
looks suspicious: appends skb after previously enqueued one, but in
the meantime this previous skb could be removed from the queue.

This patch Fixes it the simple way, so this is not fully compatible with

11 years agobluetooth: rfcomm_dev_state_change deadlock fix
Dave Young [Mon, 2 Jun 2008 06:50:52 +0000]
bluetooth: rfcomm_dev_state_change deadlock fix

There's logic in __rfcomm_dlc_close:
rfcomm_dlc_lock(d);
d->state = BT_CLOSED;
d->state_changed(d, err);
rfcomm_dlc_unlock(d);

In rfcomm_dev_state_change, it's possible that rfcomm_dev_put try to
take the dlc lock, then we will deadlock.

Here fixed it by unlock dlc before rfcomm_dev_get in
rfcomm_dev_state_change.

why not unlock just before rfcomm_dev_put? it's because there's
another problem.  rfcomm_dev_get/rfcomm_dev_del will take
rfcomm_dev_lock, but in rfcomm_dev_add the lock order is :
rfcomm_dev_lock --> dlc lock

so I unlock dlc before the taken of rfcomm_dev_lock.

Actually it's a regression caused by commit
1905f6c736cb618e07eca0c96e60e3c024023428 ("bluetooth :
__rfcomm_dlc_close lock fix"), the dlc state_change could be two
callbacks : rfcomm_sk_state_change and rfcomm_dev_state_change. I
missed the rfcomm_sk_state_change that time.

Thanks Arjan van de Ven <arjan@linux.intel.com> for the effort in
commit 4c8411f8c115def968820a4df6658ccfd55d7f1a ("bluetooth: fix

kbuild: fix $(src) assignmnet with external modules

When we introduced support for KBUILD_EXTRA_SYMBOLS
we started to include the externam module's kbuild
file when doing the final modpost step.

As external modules often do:
ccflags-y := -I$(src)

We had problems because $(src) was unassinged and
gcc then used the next parameter for -I resulting in
strange build failures.

Fix is to assign $(src) and $(obj) when building
external modules.

The following commit (4c9bf4e799ce06a7378f1196587084802a414c03):
libata: replace tf_read with qc_fill_rtf for non-SFF drivers

Broke the sata_fsl.c driver in 2.6.26-rc.  I know the following patch fixes
the issue, it clearly also adds port multipler support.  The current
2.6.26-rc driver is broken.

On boot with debug enabled we get something like (w/o this patch):

spurious interrupt!!, CC = 0x1
interrupt status 0x1
xx_scr_read, reg_in = 1

xx_scr_read, reg_in = 1
spurious interrupt!!, CC = 0x1
interrupt status 0x1

.. continues for ever.

ICH8M on macbooks are peculiar in that some of them lock up when the

yet others hang on SIDPR access.  Also, the ich8m_apple_sata entry was

If/when support is added for other SOC variants, we'll need

Input: rename SW_RADIO to SW_RFKILL_ALL

The SW_RADIO code for EV_SW events has a name that is not descriptive
enough of its intended function, and could induce someone to think
KEY_RADIO is its EV_KEY counterpart, which is false.

Rename it to SW_RFKILL_ALL, and document what this event is for.  Keep
the old name around, to avoid userspace ABI breaks.

The SW_RFKILL_ALL event is meant to be used by rfkill master switches.  It
is not bound to a particular radio switch type, and usually applies to all

llc_state_process that calls sock_queue_rcv_skb, that in turn calls
skb_set_owner_r again making the space allowed to be used by the socket to be
leaked, making the socket to get stuck.

Fix it by setting skb->sk at llc_sap_rcv and leave the accounting to be done
only at sock_queue_rcv_skb.

[S390] sclp_vt220: fix scheduling while atomic bug.

The driver incorrectly assumed that putchar will only be called from
schedulable process context and therefore blocked and waited if no
free output buffers where available.
Since putchar may also be called from BH context this may lead to
deadlocks.
To fix this just return the number of characters accepted and let the
upper layer handle the rest.

The console write function will busy wait (sclp_sync_wait) until a
buffer is available again.

[S390] showmem: Only walk spanned pages.

Convert show_mem() so its nearly the same as on x86/powerpc.
Gives us proper locking and we get also rid of the only use of max_mapnr.
Also the number of pages was contained in an int which might not be
sufficient not too far in the future.

Heiko Carstens [Fri, 30 May 2008 08:03:27 +0000]
[S390] Fix section mismatch warnings.

This fixes the last remaining section mismatch warnings in s390
architecture code. It reveals also a real bug introduced by... me
with git commit 2069e978d5a6e7b45d58027e3de7f879b8c5e488
("[S390] sparsemem vmemmap: initialize memmap.")

Calling the generic vmemmap_alloc_block() function to get initialized
memory is a nice idea, however that function is __meminit annotated
and therefore the function might be gone if we try to call it later.
This can happen if a DCSS segment gets added.

So basically revert the patch and clear the memmap explicitly to fix
the original bug.
