12 years ago[SG] Get rid of __sg_mark_end()
Jens Axboe [Wed, 31 Oct 2007 11:06:37 +0000]
[SG] Get rid of __sg_mark_end()

sg_mark_end() overwrites the page_link information, but all users want
__sg_mark_end() behaviour where we just set the end bit. That is the most
natural way to use the sg list, since you'll fill it in and then mark the
end point.

So change sg_mark_end() to only set the termination bit. Add a sg_magic
debug check as well, and clear a chain pointer if it is set.

12 years ago[TCP]: Process DSACKs that reside within a SACK block
Ilpo Järvinen [Thu, 1 Nov 2007 07:09:37 +0000]
[TCP]: Process DSACKs that reside within a SACK block

DSACK inside another SACK block were missed if start_seq of DSACK
was larger than SACK block's because sorting prioritizes full
processing of the SACK block before DSACK. After SACK block
sorting situation is like this:

             SSSSSSSSS
                  D
                        SSSSSS
                               SSSSSSS

Because write_queue is walked in-order, when the first SACK block
has been processed, TCP is already past the skb for which the
DSACK arrived and we haven't taught it to backtrack (nor should
we), so TCP just continues processing by going to the next SACK
block after the DSACK (if any).

Whenever such DSACK is present, do an embedded checking during
the previous SACK block.

If the DSACK is below snd_una, there won't be overlapping SACK
block, and thus no problem in that case. Also if start_seq of
the DSACK is equal to the actual block, it will be processed
first.

Tested this by using netem to duplicate 15% of packets, and
by printing SACK block when found_dup_sack is true and the
selected skb in the dup_sack = 1 branch (if taken):

  SACK block 0: 4344-5792 (relative to snd_una 2019137317)
  SACK block 1: 4344-5792 (relative to snd_una 2019137317)

equal start seqnos => next_dup = 0, dup_sack = 1 won't occur...

  SACK block 0: 5792-7240 (relative to snd_una 2019214061)
  SACK block 1: 2896-7240 (relative to snd_una 2019214061)
  DSACK skb match 5792-7240 (relative to snd_una)

...and next_dup = 1 case (after the not shown start_seq sort),
went to dup_sack = 1 branch.

Remove broken ptrace() special-case code from file mapping

However, Nick broke that by mistake when doing the new fault handling in

nopage into fault (fixes nonlinear)".  The breakage caused a hang with
gdb when trying to access the invalid page.

The ptrace "feature" really isn't worth resurrecting, since it really is
wrong both from a portability _and_ from an internal page cache validity
standpoint.  So this removes those old broken remnants, and fixes the

[ARM] 4634/1: DaVinci GPIO header build fix

This fixes a build problem with GPIOs on DaVinci.  Since it inlines
operations for on-chip GPIOs, it needs some headers to support those
direct register accesses.  Those headers won't be included on other
platforms, since they don't have that optimization.

[NET]: Fix incorrect sg_mark_end() calls.

This fixes scatterlist corruptions added by

commit 68e3f5dd4db62619fdbe520d36c9ebf62e672256
[CRYPTO] users: Fix up scatterlist conversion errors

The issue is that the code calls sg_mark_end() which clobbers the
sg_page() pointer of the final scatterlist entry.

The first part fo the fix makes skb_to_sgvec() do __sg_mark_end().

After considering all skb_to_sgvec() call sites the most correct
solution is to call __sg_mark_end() in skb_to_sgvec() since that is
what all of the callers would end up doing anyways.

I suspect this might have fixed some problems in virtio_net which is
the sole non-crypto user of skb_to_sgvec().

Other similar sg_mark_end() cases were converted over to
__sg_mark_end() as well.

Arguably sg_mark_end() is a poorly named function because it doesn't
just "mark", it clears out the page pointer as a side effect, which is
what led to these bugs in the first place.

The one remaining plain sg_mark_end() call is in scsi_alloc_sgtable()
and arguably it could be converted to __sg_mark_end() if only so that
we can delete this confusing interface from linux/scatterlist.h

[NETNS]: fix net released by rcu callback

When a network namespace reference is held by a network subsystem,
and when this reference is decremented in a rcu update callback, we
must ensure that there is no more outstanding rcu update before
trying to free the network namespace.

In the normal case, the rcu_barrier is called when the network namespace
is exiting in the cleanup_net function.

But when a network namespace creation fails, and the subsystems are
undone (like the cleanup), the rcu_barrier is missing.

12 years ago[NET]: Fix free_netdev on register_netdev failure.
Daniel Lezcano [Tue, 30 Oct 2007 22:38:18 +0000]
[NET]: Fix free_netdev on register_netdev failure.

Point 1:
The unregistering of a network device schedule a netdev_run_todo.
This function calls dev->destructor when it is set and the
destructor calls free_netdev.

Point 2:
In the case of an initialization of a network device the usual code
is:
 * alloc_netdev
 * register_netdev
    -> if this one fails, call free_netdev and exit with error.

Point 3:
In the register_netdevice function at the later state, when the device
is at the registered state, a call to the netdevice_notifiers is made.
If one of the notification falls into an error, a rollback to the
registered state is done using unregister_netdevice.

Conclusion:
When a network device fails to register during initialization because
one network subsystem returned an error during a notification call
chain, the network device is freed twice because of fact 1 and fact 2.
The second free_netdev will be done with an invalid pointer.

Proposed solution:
The following patch move all the code of unregister_netdevice *except*
the call to net_set_todo, to a new function "rollback_registered".

The following functions are changed in this way:
 * register_netdevice: calls rollback_registered when a notification fails
 * unregister_netdevice: calls rollback_register + net_set_todo, the call
                         order to net_set_todo is changed because it is the
                         latest now. Since it justs add an element to a list
                         that should not break anything.

12 years agodio: fix cache invalidation after sync writes
Zach Brown [Tue, 30 Oct 2007 18:45:46 +0000]
dio: fix cache invalidation after sync writes

Commit commit 65b8291c4000e5f38fc94fb2ca0cb7e8683c8a1b ("dio: invalidate
clean pages before dio write") introduced a bug which stopped dio from
ever invalidating the page cache after writes.  It still invalidated it
before writes so most users were fine.

Karl Schendel reported ( http://lkml.org/lkml/2007/10/26/481 ) hitting
this bug when he had a buffered reader immediately reading file data
after an O_DIRECT wirter had written the data.  The kernel issued
read-ahead beyond the position of the reader which overlapped with the
O_DIRECT writer.  The failure to invalidate after writes caused the
reader to see stale data from the read-ahead.

The following patch is originally from Karl.  The following commentary
is his:

The below 3rd try takes on your suggestion of just invalidating
no matter what the retval from the direct_IO call.  I ran it
thru the test-case several times and it has worked every time.
The post-invalidate is probably still too early for async-directio,
but I don't have a testcase for that;  just sync.  And, this
won't be any worse in the async case.

I added a test to the aio-dio-regress repository which mimics Karl's IO
pattern.  It verifed the bad behaviour and that the patch fixed it.  I
agree with Karl, this still doesn't help the case where a buffered
reader follows an AIO O_DIRECT writer.  That will require a bit more
work.

This gives up on the idea of returning EIO to indicate to userspace that
stale data remains if the invalidation failed.

For now, fix this just by bailing out after a few iterations.  We may

Hugh Dickins [Mon, 29 Oct 2007 21:37:20 +0000]
fix tmpfs BUG and AOP_WRITEPAGE_ACTIVATE

It's possible to provoke unionfs (not yet in mainline, though in mm and
some distros) to hit shmem_writepage's BUG_ON(page_mapped(page)).  I expect
it's possible to provoke the 2.6.23 ecryptfs in the same way (but the
2.6.24 ecryptfs no longer calls lower level's ->writepage).

This came to light with the recent find that AOP_WRITEPAGE_ACTIVATE could
leak from tmpfs via write_cache_pages and unionfs to userspace.  There's
already a fix (e423003028183df54f039dfda8b58c49e78c89d7 - writeback: don't
propagate AOP_WRITEPAGE_ACTIVATE) in the tree for that, and it's okay so
far as it goes; but insufficient because it doesn't address the underlying
issue, that shmem_writepage expects to be called only by vmscan (relying on
backing_dev_info capabilities to prevent the normal writeback path from
ever approaching it).

That's an increasingly fragile assumption, and ramdisk_writepage (the other
source of AOP_WRITEPAGE_ACTIVATEs) is already careful to check
wbc->for_reclaim before returning it.  Make the same check in
shmem_writepage, thereby sidestepping the page_mapped BUG also.

12 years agomm/sparse-vmemmap.c: make sure init_mm is included
Glauber de Oliveira Costa [Mon, 29 Oct 2007 21:37:19 +0000]
mm/sparse-vmemmap.c: make sure init_mm is included

mm/sparse-vmemmap.c uses init_mm in some places.  However, it is not
present in any of the headers currently included in the file.

init_mm is defined as extern in sched.h, so we add it to the headers list

Up to now, this problem was masked by the fact that functions like
set_pte_at() and pmd_populate_kernel() are usually macros that expand to
simpler variants that does not use the first parameter at all.

Remove bogus default y for DMAR and NET_DMA

No reason I can think of of making them default y Most people don't have
the hardware and with default y they just pollute lots of configs during
make oldconfig.

sunrpc: fix rpc debugging

Commit baa3a2a0d24ebcf1c451bec8e5bee3d3467f4cbb ("sysctl: remove broken
sunrpc debug binary sysctls"), by removing initialization of the
ctl_name field, broke this conditional, preventing the display of
rpc_tasks that you previously got when turning on rpc debugging.

radeonfb: remove warning with CONFIG_PM=n

Remove warning from powerpc ppc64_defconfig builds:

drivers/video/aty/radeon_pm.c:30: warning: 'radeon_reinitialize_M10' declared 'static' but never defined

It's used only under CONFIG_PM, and only with CONFIG_X86 before it is
defined, so the forward declaration can be moved under the ifdef.
