#1574078 — [PATCH 3.10 275/319] ipc: remove use of seq_printf return value

From: Joe Perches <joe@perches.com>

commit 7f032d6ef6154868a2a5d5f6b2c3f8587292196c upstream.

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.

See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
     seq_has_overflowed() and make public")

Is this necessary?  It doesn't seem so.

This one seems an unlikely candidate to backport as
it effectively doesn't do anything but prepare for
seq_printf return value removal.

Is that removal going to be backported too or is this
being patched to avoid some other backported patch's
desire to be applied without offsets?

Hmmm sorry, I missed the comment on this one, it was picked
because it makes it easier to apply "ipc/sem.c: fix
complex_count vs. simple op race". This latter was picked
as-is from Jiri's 3.12 tree so I preferred to avoid modifying
it. I'll just mention it in the commit message.

Thanks for notifying me.

#1574080 — [PATCH 3.10 307/319] PCI: Handle read-only BARs on AMD CS553x devices

From: Myron Stowe <myron.stowe@redhat.com>

commit 06cf35f903aa6da0cc8d9f81e9bcd1f7e1b534bb upstream.

Some AMD CS553x devices have read-only BARs because of a firmware or
hardware defect.  There's a workaround in quirk_cs5536_vsa(), but it no
longer works after 36e8164882ca ("PCI: Restore detection of read-only
BARs").  Prior to 36e8164882ca, we filled in res->start; afterwards we
leave it zeroed out.  The quirk only updated the size, so the driver tried
to use a region starting at zero, which didn't work.

Expand quirk_cs5536_vsa() to read the base addresses from the BARs and
hard-code the sizes.

On Nix's system BAR 2's read-only value is 0x6200.  Prior to 36e8164882ca,
we interpret that as a 512-byte BAR based on the lowest-order bit set.  Per
datasheet sec 5.6.1, that BAR (MFGPT) requires only 64 bytes; use that to
avoid clearing any address bits if a platform uses only 64-byte alignment.

[js] pcibios_bus_to_resource takes pdev, not bus in 3.12

#1574082 — [PATCH 3.10 284/319] drbd: Fix kernel_sendmsg() usage - potential NULL deref

From: Richard Weinberger <richard@nod.at>

commit d8e9e5e80e882b4f90cba7edf1e6cb7376e52e54 upstream.

Don't pass a size larger than iov_len to kernel_sendmsg().
Otherwise it will cause a NULL pointer deref when kernel_sendmsg()
returns with rv < size.

DRBD as external module has been around in the kernel 2.4 days already.
We used to be compatible to 2.4 and very early 2.6 kernels,
we used to use
 rv = sock_sendmsg(sock, &msg, iov.iov_len);
then later changed to
 rv = kernel_sendmsg(sock, &msg, &iov, 1, size);
when we should have used
 rv = kernel_sendmsg(sock, &msg, &iov, 1, iov.iov_len);

tcp_sendmsg() used to totally ignore the size parameter.
 57be5bd ip: convert tcp_sendmsg() to iov_iter primitives
changes that, and exposes our long standing error.

Even with this error exposed, to trigger the bug, we would need to have
an environment (config or otherwise) causing us to not use sendpage()
for larger transfers, a failing connection, and have it fail "just at the
right time".  Apparently that was unlikely enough for most, so this went
unnoticed for years.

Still, it is known to trigger at least some of these,
and suspected for the others:
[0] http://lists.linbit.com/pipermail/drbd-user/2016-July/023112.html
[1] http://lists.linbit.com/pipermail/drbd-dev/2016-March/003362.html
[2] https://forums.grsecurity.net/viewtopic.php?f=3&t=4546
[3] https://ubuntuforums.org/showthread.php?t=2336150
[4] http://e2.howsolveproblem.com/i/1175162/

This should go into 4.9,
and into all stable branches since and including v4.0,
which is the first to contain the exposing change.

It is correct for all stable branches older than that as well
(which contain the DRBD driver; which is 2.6.33 and up).

It requires a small "conflict" resolution for v4.4 and earlier, with v4.5
we dropped the comment block immediately preceding the kernel_sendmsg().

#1574084 — [PATCH 3.10 242/319] iwlwifi: pcie: fix access to scratch buffer

From: Sara Sharon <sara.sharon@intel.com>

commit d5d0689aefc59c6a5352ca25d7e6d47d03f543ce upstream.

This fixes a pretty ancient bug that hasn't manifested itself
until now.
The scratchbuf for command queue is allocated only for 32 slots
but is accessed with the queue write pointer - which can be
up to 256.
Since the scratch buf size was 16 and there are up to 256 TFDs
we never passed a page boundary when accessing the scratch buffer,
but when attempting to increase the size of the scratch buffer a
panic was quick to follow when trying to access the address resulted
in a page boundary.

commit 7bd3e239d6c6d1cad276e8f130b386df4234dcd7 upstream.

The fact that volatile allows for atomic load/stores is a special case
not a requirement for {READ,WRITE}_ONCE(). Their primary purpose is to
force the compiler to emit load/stores _once_.

#1574086 — [PATCH 3.10 256/319] packet: call fanout_release, while UNREGISTERING a netdev

From: Anoob Soman <anoob.soman@citrix.com>

commit 6664498280cf17a59c3e7cf1a931444c02633ed1 upstream.

If a socket has FANOUT sockopt set, a new proto_hook is registered
as part of fanout_add(). When processing a NETDEV_UNREGISTER event in
af_packet, __fanout_unlink is called for all sockets, but prot_hook which was
registered as part of fanout_add is not removed. Call fanout_release, on a
NETDEV_UNREGISTER, which removes prot_hook and removes fanout from the
fanout_list.

This fixes BUG_ON(!list_empty(&dev->ptype_specific)) in netdev_run_todo()

#1574088 — [PATCH 3.10 286/319] tools/vm/slabinfo: fix an unintentional printf

#1574089 — [PATCH 3.10 199/319] IB/srpt: Simplify srpt_handle_tsk_mgmt()

From: Bart Van Assche <bart.vanassche@sandisk.com>

commit 51093254bf879bc9ce96590400a87897c7498463 upstream.

Let the target core check task existence instead of the SRP target
driver. Additionally, let the target core check the validity of the
task management request instead of the ib_srpt driver.

This patch fixes the following kernel crash:

#1574091 — [PATCH 3.10 233/319] tcp: fix overflow in __tcp_retransmit_skb()

From: Eric Dumazet <edumazet@google.com>

commit ffb4d6c8508657824bcef68a36b2a0f9d8c09d10 upstream.

If a TCP socket gets a large write queue, an overflow can happen
in a test in __tcp_retransmit_skb() preventing all retransmits.

The flow then stalls and resets after timeouts.

Tested:

sysctl -w net.core.wmem_max=1000000000
netperf -H dest -- -s 1000000000

If we hold the superblock lock while calling reiserfs_quota_on_mount(), we can
deadlock our own worker - mount blocks kworker/3:2, sleeps forever more.

The problem happens when you call ioctl(SNDRV_TIMER_IOCTL_CONTINUE) on a
completely new/unused timer -- it will have ->sticks == 0, which causes a
divide by 0 in snd_hrtimer_callback().

#1574094 — [PATCH 3.10 231/319] tcp: fix use after free in tcp_xmit_retransmit_queue()

From: Eric Dumazet <edumazet@google.com>

commit bb1fceca22492109be12640d49f5ea5a544c6bb4 upstream.

When tcp_sendmsg() allocates a fresh and empty skb, it puts it at the
tail of the write queue using tcp_add_write_queue_tail()

Then it attempts to copy user data into this fresh skb.

If the copy fails, we undo the work and remove the fresh skb.

Unfortunately, this undo lacks the change done to tp->highest_sack and
we can leave a dangling pointer (to a freed skb)

Later, tcp_xmit_retransmit_queue() can dereference this pointer and
access freed memory. For regular kernels where memory is not unmapped,
this might cause SACK bugs because tcp_highest_sack_seq() is buggy,
returning garbage instead of tp->snd_nxt, but with various debug
features like CONFIG_DEBUG_PAGEALLOC, this can crash the kernel.

This bug was found by Marco Grassi thanks to syzkaller.

Fixes: 6859d49475d4 ("[TCP]: Abstract tp->highest_sack accessing & point to next skb")
