#1369747 — [PATCH 3.19.y-ckt 129/170] ath9k: fix misleading indentation

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: Arnd Bergmann <arnd@arndb.de>

commit 362210e0dff4eb7bb36a9b34dbef3b39d779d95e upstream.

A cleanup patch in linux-3.18 moved around some code in the ath9k
driver and left some code to be indented in a misleading way,
made worse by the addition of some new code for p2p mode, as
discovered by a new gcc-6 warning:

drivers/net/wireless/ath/ath9k/init.c: In function 'ath9k_set_hw_capab':
drivers/net/wireless/ath/ath9k/init.c:851:4: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation]
    hw->wiphy->iface_combinations = if_comb;
    ^~
drivers/net/wireless/ath/ath9k/init.c:847:3: note: ...this 'if' clause, but it is not
   if (ath9k_is_chanctx_enabled())
   ^~

The code is in fact correct, but the indentation is not, so I'm
reformatting it as it should have been after the original cleanup.

#1369748 — [PATCH 3.19.y-ckt 130/170] sctp: fix the transports round robin issue when init is retransmitted

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: Xin Long <lucien.xin@gmail.com>

commit 39d2adebf137de5f900843f69f5e500932e31047 upstream.

prior to this patch, at the beginning if we have two paths in one assoc,
they may have the same params other than the last_time_heard, it will try
the paths like this:

1st cycle
  try trans1 fail.
  then trans2 is selected.(cause it's last_time_heard is after trans1).

2nd cycle:
  try  trans2 fail
  then trans2 is selected.(cause it's last_time_heard is after trans1).

3rd cycle:
  try  trans2 fail
  then trans2 is selected.(cause it's last_time_heard is after trans1).

....

trans1 will never have change to be selected, which is not what we expect.
we should keeping round robin all the paths if they are just added at the
beginning.

So at first every tranport's last_time_heard should be initialized 0, so
that we ensure they have the same value at the beginning, only by this,
all the transports could get equal chance to be selected.

Then for sctp_trans_elect_best, it should return the trans_next one when
*trans == *trans_next, so that we can try next if it fails,  but now it
always return trans. so we can fix it by exchanging these two params when
we calls sctp_trans_elect_tie().

#1369749 — [PATCH 3.19.y-ckt 096/170] mmc: mmc_spi: Add Card Detect comments and fix CD GPIO case

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: Magnus Damm <damm+renesas@opensource.se>

commit bcdc9f260bdce09913db1464be9817170d51044a upstream.

This patch fixes the MMC SPI driver from doing polling card detect when a
CD GPIO that supports interrupts is specified using the gpios DT property.

Without this patch the DT node below results in the following output:

 spi_gpio: spi-gpio { /* SD2 @ CN12 */
         compatible = "spi-gpio";
         #address-cells = <1>;
         #size-cells = <0>;
         gpio-sck = <&gpio6 16 GPIO_ACTIVE_HIGH>;
         gpio-mosi = <&gpio6 17 GPIO_ACTIVE_HIGH>;
         gpio-miso = <&gpio6 18 GPIO_ACTIVE_HIGH>;
         num-chipselects = <1>;
         cs-gpios = <&gpio6 21 GPIO_ACTIVE_LOW>;
         status = "okay";

         spi@0 {
                 compatible = "mmc-spi-slot";
                 reg = <0>;
                 voltage-ranges = <3200 3400>;
                 spi-max-frequency = <25000000>;
                 gpios = <&gpio6 22 GPIO_ACTIVE_LOW>;   /* CD */
         };
 };

 # dmesg | grep mmc
 mmc_spi spi32766.0: SD/MMC host mmc0, no WP, no poweroff, cd polling
 mmc0: host does not support reading read-only switch, assuming write-enable
 mmc0: new SDHC card on SPI
 mmcblk0: mmc0:0000 SU04G 3.69 GiB
 mmcblk0: p1

With this patch applied the "cd polling" portion above disappears.

#1369750 — [PATCH 3.19.y-ckt 107/170] tracing: Fix crash from reading trace_pipe with sendfile

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

commit a29054d9478d0435ab01b7544da4f674ab13f533 upstream.

If tracing contains data and the trace_pipe file is read with sendfile(),
then it can trigger a NULL pointer dereference and various BUG_ON within the
VM code.

There's a patch to fix this in the splice_to_pipe() code, but it's also a
good idea to not let that happen from trace_pipe either.

From: Oliver Neukum <oneukum@suse.com>

commit 0b818e3956fc1ad976bee791eadcbb3b5fec5bfd upstream.

Attacks that trick drivers into passing a NULL pointer
to usb_driver_claim_interface() using forged descriptors are
known. This thwarts them by sanity checking.

#1369752 — [PATCH 3.19.y-ckt 132/170] megaraid_sas: add missing curly braces in ioctl handler

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: Arnd Bergmann <arnd@arndb.de>

commit 3deb9438d34a09f6796639b652a01d110aca9f75 upstream.

gcc-6 found a dubious indentation in the megasas_mgmt_fw_ioctl
function:

drivers/scsi/megaraid/megaraid_sas_base.c: In function 'megasas_mgmt_fw_ioctl':
drivers/scsi/megaraid/megaraid_sas_base.c:6658:4: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation]
    kbuff_arr[i] = NULL;
    ^~~~~~~~~
drivers/scsi/megaraid/megaraid_sas_base.c:6653:3: note: ...this 'if' clause, but it is not
   if (kbuff_arr[i])
   ^~

The code is actually correct, as there is no downside in clearing a NULL
pointer again.

This clarifies the code and avoids the warning by adding extra curly
braces.

#1369753 — [PATCH 3.19.y-ckt 079/170] EDAC/sb_edac: Fix computation of channel address

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: "Luck, Tony" <tony.luck@intel.com>

commit eb1af3b71f9d83e45f2fd2fd649356e98e1c582c upstream.

Large memory Haswell-EX systems with multiple DIMMs per channel were
sometimes reporting the wrong DIMM.

Found three problems:

 1) Debug printouts for socket and channel interleave were not interpreting
    the register fields correctly. The socket interleave field is a 2^X
    value (0=1, 1=2, 2=4, 3=8). The channel interleave is X+1 (0=1, 1=2,
    2=3. 3=4).

 2) Actual use of the socket interleave value didn't interpret as 2^X

 3) Conversion of address to channel address was complicated, and wrong.

#1369755 — [PATCH 3.19.y-ckt 112/170] KVM: fix spin_lock_init order on x86

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: Paolo Bonzini <pbonzini@redhat.com>

commit e9ad4ec8379ad1ba6f68b8ca1c26b50b5ae0a327 upstream.

Moving the initialization earlier is needed in 4.6 because
kvm_arch_init_vm is now using mmu_lock, causing lockdep to
complain:

[  284.440294] INFO: trying to register non-static key.
[  284.445259] the code is fine but needs lockdep annotation.

[  284.574740]  [<ffffffffa02bff3f>] kvm_dev_ioctl+0xbf/0x4d0 [kvm]

However, it also helps fixing a preexisting problem, which is why this
patch is also good for stable kernels: kvm_create_vm was incrementing
current->mm->mm_count but not decrementing it at the out_err label (in
case kvm_init_mmu_notifier failed).  The new initialization order makes
it possible to add the required mmdrop without adding a new error label.

From: Arnaldo Carvalho de Melo <acme@redhat.com>

commit 34b88a68f26a75e4fded796f1a49c40f82234b7d upstream.

The syzkaller fuzzer hit the following use-after-free:

  Call Trace:
   [<ffffffff8175ea0e>] __asan_report_load8_noabort+0x3e/0x40 mm/kasan/report.c:295
   [<ffffffff851cc31a>] __sys_recvmmsg+0x6fa/0x7f0 net/socket.c:2261

   [<ffffffff86332bb6>] entry_SYSCALL_64_fastpath+0x16/0x7a
  arch/x86/entry/entry_64.S:185

And, as Dmitry rightly assessed, that is because we can drop the
reference and then touch it when the underlying recvmsg calls return
some packets and then hit an error, which will make recvmmsg to set
sock->sk->sk_err, oops, fix it.

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

commit cb86e05390debcc084cfdb0a71ed4c5dbbec517d upstream.

Joel Fernandes reported that the function tracing of preempt disabled
sections was not being reported when running either the preemptirqsoff or
preemptoff tracers. This was due to the fact that the function tracer
callback for those tracers checked if irqs were disabled before tracing. But
this fails when we want to trace preempt off locations as well.

Joel explained that he wanted to see funcitons where interrupts are enabled
but preemption was disabled. The expected output he wanted:

   <...>-2265    1d.h1 3419us : preempt_count_sub <-irq_exit
   <...>-2265    1d..1 3419us : __do_softirq <-irq_exit

   <...>-2265    1d.s2 3422us : _raw_spin_unlock_irq <-run_timer_softirq
   <...>-2265    1..s2 3422us : preempt_count_sub <-_raw_spin_unlock_irq
   <...>-2265    1..s1 3423us : rcu_bh_qs <-__do_softirq

   <...>-2265    1d.s1 3423us : __local_bh_enable <-__do_softirq

There's a comment saying that the irq disabled check is because there's a
possible race that tracing_cpu may be set when the function is executed. But
I don't remember that race. For now, I added a check for preemption being
enabled too to not record the function, as there would be no race if that
was the case. I need to re-investigate this, as I'm now thinking that the
tracing_cpu will always be correct. But no harm in keeping the check for
now, except for the slight performance hit.

#1369762 — [PATCH 3.19.y-ckt 097/170] nfsd: fix deadlock secinfo+readdir compound

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: "J. Bruce Fields" <bfields@redhat.com>

commit 2f6fc056e899bd0144a08da5cacaecbe8997cd74 upstream.

nfsd_lookup_dentry exits with the parent filehandle locked.  fh_put also
unlocks if necessary (nfsd filehandle locking is probably too lenient),
so it gets unlocked eventually, but if the following op in the compound
needs to lock it again, we can deadlock.

A fuzzer ran into this; normal clients don't send a secinfo followed by
a readdir in the same compound.

#1369763 — [PATCH 3.19.y-ckt 110/170] target: Fix target_release_cmd_kref shutdown comp leak

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: Himanshu Madhani <himanshu.madhani@qlogic.com>

commit 5e47f1985d7107331c3f64fb3ec83d66fd73577e upstream.

This patch fixes an active I/O shutdown bug for fabric
drivers using target_wait_for_sess_cmds(), where se_cmd
descriptor shutdown would result in hung tasks waiting
indefinitely for se_cmd->cmd_wait_comp to complete().

To address this bug, drop the incorrect list_del_init()
usage in target_wait_for_sess_cmds() and always complete()
during se_cmd target_release_cmd_kref() put, in order to
let caller invoke the final fabric release callback
into se_cmd->se_tfo->release_cmd() code.

Since 4.4, I've been able to trigger this occasionally:

#1369766 — [PATCH 3.19.y-ckt 125/170] ppp: take reference on channels netns

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: Guillaume Nault <g.nault@alphalink.fr>

commit 1f461dcdd296eecedaffffc6bae2bfa90bd7eb89 upstream.

Let channels hold a reference on their network namespace.
Some channel types, like ppp_async and ppp_synctty, can have their
userspace controller running in a different namespace. Therefore they
can't rely on them to preclude their netns from being removed from
under them.

#1369767 — [PATCH 3.19.y-ckt 118/170] MAINTAINERS: Update mailing list and web page for hwmon subsystem

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: Guenter Roeck <linux@roeck-us.net>

commit 968ce1b1f45a7d76b5471b19bd035dbecc72f32d upstream.

The old web page for the hwmon subsystem is no longer operational,
and the mailing list has become unreliable. Move both to kernel.org.

#1369768 — [PATCH 3.19.y-ckt 093/170] net: mvneta: enable change MAC address when interface is up

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: Dmitri Epshtein <dima@marvell.com>

commit 928b6519afeb2a5e2dc61154380b545ed66c476a upstream.

Function eth_prepare_mac_addr_change() is called as part of MAC
address change. This function check if interface is running.
To enable change MAC address when interface is running:
IFF_LIVE_ADDR_CHANGE flag must be set to dev->priv_flags field
