#1352104 — [PATCH 4.2.y-ckt 254/273] s390/perf_event: fix address range for asynchronous stack

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Heiko Carstens <heiko.carstens@de.ibm.com>

commit 1f8cbb9c8365061d8b866e9b4f4403e029d57989 upstream.

git commit dc7ee00d4771 ("s390: lowcore stack pointer offsets")
introduced a regression in regard to perf_callchain_kernel(). The
stack pointer for the asynchronous stack in the lowcore now has an
additional offset applied. This offset needs to be taken into account
in the calculation for the low and high address for the stack.

This bug was already partially fixed with 9cc5c206d9b4
("s390/dumpstack: fix address ranges for asynchronous and panic
stack"). This patch fixes it also for the perf_event code.

#1352105 — [PATCH 4.2.y-ckt 266/273] bonding: don't use stale speed and duplex information

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Jay Vosburgh <jay.vosburgh@canonical.com>

commit 266b495f11d6706018f66250cb02a788ff2490d7 upstream.

There is presently a race condition between the bonding periodic
link monitor and the updating of a slave's speed and duplex.  The former
occurs on a periodic basis, and the latter in response to a driver's
calling of netif_carrier_on.

	It is possible for the periodic monitor to run between the
driver call of netif_carrier_on and the receipt of the NETDEV_CHANGE
event that causes bonding to update the slave's speed and duplex.  This
manifests most notably as a report that a slave is up and "0 Mbps full
duplex" after enslavement, but in principle could report an incorrect
speed and duplex after any link up event if the device comes up with a
different speed or duplex.  This affects the 802.3ad aggregator
selection, as the speed and duplex are selection criteria.

	This is fixed by updating the speed and duplex in the periodic
monitor, prior to using that information.

	This was done historically in bonding, but the call to
bond_update_speed_duplex was removed in commit 876254ae2758 ("bonding:
don't call update_speed_duplex() under spinlocks"), as it might sleep
under lock.  Later, the locking was changed to only hold RTNL, and so
after commit 876254ae2758 ("bonding: don't call update_speed_duplex()
under spinlocks") this call is again safe.

#1352106 — [PATCH 4.2.y-ckt 245/273] net/mlx4_en: Choose time-stamping shift value according to HW frequency

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Eugenia Emantayev <eugenia@mellanox.com>

[ Upstream commit 31c128b66e5b28f468076e4f3ca3025c35342041 ]

Previously, the shift value used for time-stamping was constant and didn't
depend on the HW chip frequency. Change that to take the frequency into account
and calculate the maximal value in cycles per wraparound of ten seconds. This
time slot was chosen since it gives a good accuracy in time synchronization.

Algorithm for shift value calculation:
 * Round up the maximal value in cycles to nearest power of two

 * Calculate maximal multiplier by division of all 64 bits set
   to above result

 * Then, invert the function clocksource_khz2mult() to get the shift from
   maximal mult value

#1352107 — [PATCH 4.2.y-ckt 242/273] af_unix: Guard against other == sk in unix_dgram_sendmsg

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Rainer Weikusat <rweikusat@mobileactivedefense.com>

[ Upstream commit a5527dda344fff0514b7989ef7a755729769daa1 ]

The unix_dgram_sendmsg routine use the following test

if (unlikely(unix_peer(other) != sk && unix_recvq_full(other))) {

to determine if sk and other are in an n:1 association (either
established via connect or by using sendto to send messages to an
unrelated socket identified by address). This isn't correct as the
specified address could have been bound to the sending socket itself or
because this socket could have been connected to itself by the time of
the unix_peer_get but disconnected before the unix_state_lock(other). In
both cases, the if-block would be entered despite other == sk which
might either block the sender unintentionally or lead to trying to unlock
the same spin lock twice for a non-blocking send. Add a other != sk
check to guard against this.

#1352108 — [PATCH 4.2.y-ckt 239/273] bpf: fix branch offset adjustment on backjumps after patching ctx expansion

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Daniel Borkmann <daniel@iogearbox.net>

[ Upstream commit a1b14d27ed0965838350f1377ff97c93ee383492 ]

When ctx access is used, the kernel often needs to expand/rewrite
instructions, so after that patching, branch offsets have to be
adjusted for both forward and backward jumps in the new eBPF program,
but for backward jumps it fails to account the delta. Meaning, for
example, if the expansion happens exactly on the insn that sits at
the jump target, it doesn't fix up the back jump offset.

Analysis on what the check in adjust_branches() is currently doing:

  /* adjust offset of jmps if necessary */
  if (i < pos && i + insn->off + 1 > pos)
    insn->off += delta;
  else if (i > pos && i + insn->off + 1 < pos)
    insn->off -= delta;

First condition (forward jumps):

  Before:                         After:

  insns[0]                        insns[0]
  insns[1] <--- i/insn            insns[1] <--- i/insn
  insns[2] <--- pos               insns[P] <--- pos
  insns[3]                        insns[P]  `------| delta
  insns[4] <--- target_X          insns[P]   `-----|
  insns[5]                        insns[3]
                                  insns[4] <--- target_X
                                  insns[5]

First case is if we cross pos-boundary and the jump instruction was
before pos. This is handeled correctly. I.e. if i == pos, then this
would mean our jump that we currently check was the patchlet itself
that we just injected. Since such patchlets are self-contained and
have no awareness of any insns before or after the patched one, the
delta is correctly not adjusted. Also, for the second condition in
case of i + insn->off + 1 == pos, means we jump to that newly patched
instruction, so no offset adjustment are needed. That part is correct.

Second condition (backward jumps):

  Before:                         After:

  insns[0]                        insns[0]
  insns[1] <--- target_X          insns[1] <--- target_X
  insns[2] <--- pos <-- target_Y  insns[P] <--- pos <-- target_Y
  insns[3]                        insns[P]  `------| delta
  insns[4] <--- i/insn            insns[P]   `-----|
  insns[5]                        insns[3]
                                  insns[4] <--- i/insn
                                  insns[5]

Second interesting case is where we cross pos-boundary and the jump
instruction was after pos. Backward jump with i == pos would be
impossible and pose a bug somewhere in the patchlet, so the first
condition checking i > pos is okay only by itself. However, i +
insn->off + 1 < pos does not always work as intended to trigger the
adjustment. It works when jump targets would be far off where the
delta wouldn't matter. But, for example, where the fixed insn->off
before pointed to pos (target_Y), it now points to pos + delta, so
that additional room needs to be taken into account for the check.
This means that i) both tests here need to be adjusted into pos + delta,
and ii) for the second condition, the test needs to be <= as pos
itself can be a target in the backjump, too.

#1352110 — [PATCH 4.2.y-ckt 265/273] writeback: initialize inode members that track writeback history

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Tahsin Erdogan <tahsin@google.com>

commit 3d65ae4634ed8350aee98a4e6f4e41fe40c7d282 upstream.

inode struct members that track cgroup writeback information
should be reinitialized when inode gets allocated from
kmem_cache. Otherwise, their values remain and get used by the
new inode.

#1352112 — [PATCH 4.2.y-ckt 257/273] netlink: not trim skb for mmaped socket when dump

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

From: Ken-ichirou MATSUZAWA <chamaken@gmail.com>

commit aa3a022094fac7f6e48050e139fa8a5a2e3265ce upstream.

We should not trim skb for mmaped socket since its buf size is fixed
and userspace will read as frame which data equals head. mmaped
socket will not call recvmsg, means max_recvmsg_len is 0,
skb_reserve was not called before commit: db65a3aaf29e.

#1352115 — [PATCH 4.2.y-ckt 252/273] sctp: Fix port hash table size computation

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Neil Horman <nhorman@tuxdriver.com>

[ Upstream commit d9749fb5942f51555dc9ce1ac0dbb1806960a975 ]

Dmitry Vyukov noted recently that the sctp_port_hashtable had an error in
its size computation, observing that the current method never guaranteed
that the hashsize (measured in number of entries) would be a power of two,
which the input hash function for that table requires.  The root cause of
the problem is that two values need to be computed (one, the allocation
order of the storage requries, as passed to __get_free_pages, and two the
number of entries for the hash table).  Both need to be ^2, but for
different reasons, and the existing code is simply computing one order
value, and using it as the basis for both, which is wrong (i.e. it assumes
that ((1<<order)*PAGE_SIZE)/sizeof(bucket) is still ^2 when its not).

To fix this, we change the logic slightly.  We start by computing a goal
allocation order (which is limited by the maximum size hash table we want
to support.  Then we attempt to allocate that size table, decreasing the
order until a successful allocation is made.  Then, with the resultant
successful order we compute the number of buckets that hash table supports,
which we then round down to the nearest power of two, giving us the number
of entries the table actually supports.

I've tested this locally here, using non-debug and spinlock-debug kernels,
and the number of entries in the hashtable consistently work out to be
powers of two in all cases.

#1352116 — [PATCH 4.2.y-ckt 260/273] s390/stacktrace: fix address ranges for asynchronous and panic stack

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Heiko Carstens <heiko.carstens@de.ibm.com>

commit 9900c48c46d8bcf497972024c5fe366e6d9771f3 upstream.

git commit dc7ee00d4771 ("s390: lowcore stack pointer offsets")
introduced a regression in regard to save_stack_trace(). The stack
pointer for the asynchronous and the panic stack in the lowcore now
have an additional offset applied to them. This offset needs to be
taken into account in the calculation for the low and high address for
the stacks.

This bug was already partially fixed with 9cc5c206d9b4
("s390/dumpstack: fix address ranges for asynchronous and panic
stack"). This patch fixes it also for the stacktrace code.

#1352118 — [PATCH 4.2.y-ckt 272/273] netfilter: nfnetlink: correctly validate length of batch messages

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Phil Turnbull <phil.turnbull@oracle.com>

commit c58d6c93680f28ac58984af61d0a7ebf4319c241 upstream.

If nlh->nlmsg_len is zero then an infinite loop is triggered because
'skb_pull(skb, msglen);' pulls zero bytes.

The calculation in nlmsg_len() underflows if 'nlh->nlmsg_len <
NLMSG_HDRLEN' which bypasses the length validation and will later
trigger an out-of-bound read.

If the length validation does fail then the malformed batch message is
copied back to userspace. However, we cannot do this because the
nlh->nlmsg_len can be invalid. This leads to an out-of-bounds read in
netlink_ack:

device total dropped packets accounting to show wrong results.

Fix that. Use it for rx_fifo_errors only.

#1352121 — [PATCH 4.2.y-ckt 225/273] tipc: fix connection abort during subscription cancel

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Parthasarathy Bhuvaragan <parthasarathy.bhuvaragan@ericsson.com>

[ Upstream commit 4d5cfcba2f6ec494d8810b9e3c0a7b06255c8067 ]

In 'commit 7fe8097cef5f ("tipc: fix nullpointer bug when subscribing
to events")', we terminate the connection if the subscription
creation fails.
In the same commit, the subscription creation result was based on
the value of the subscription pointer (set in the function) instead
of the return code.

Unfortunately, the same function tipc_subscrp_create() handles
subscription cancel request. For a subscription cancellation request,
the subscription pointer cannot be set. Thus if a subscriber has
several subscriptions and cancels any of them, the connection is
terminated.

In this commit, we terminate the connection based on the return value
of tipc_subscrp_create().
Fixes: commit 7fe8097cef5f ("tipc: fix nullpointer bug when subscribing to events")

This patch will be deferred to the next 4.2-stable release (4.2.8-ckt6) 
so that it lands along with

4de13d7e tipc: fix nullptr crash during subscription cancel

... which has not yet appeared in a mainline -rc.

#1352122 — [PATCH 4.2.y-ckt 131/273] ALSA: timer: Fix race between stop and interrupt

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Takashi Iwai <tiwai@suse.de>

commit ed8b1d6d2c741ab26d60d499d7fbb7ac801f0f51 upstream.

A slave timer element also unlinks at snd_timer_stop() but it takes
only slave_active_lock.  When a slave is assigned to a master,
however, this may become a race against the master's interrupt
handling, eventually resulting in a list corruption.  The actual bug
could be seen with a syzkaller fuzzer test case in BugLink below.

As a fix, we need to take timeri->timer->lock when timer isn't NULL,
i.e. assigned to a master, while the assignment to a master itself is
protected by slave_active_lock.

#1352124 — [PATCH 4.2.y-ckt 222/273] af_unix: fix struct pid memory leak

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Eric Dumazet <edumazet@google.com>

[ Upstream commit fa0dc04df259ba2df3ce1920e9690c7842f8fa4b ]

Dmitry reported a struct pid leak detected by a syzkaller program.

Bug happens in unix_stream_recvmsg() when we break the loop when a
signal is pending, without properly releasing scm.
