#1660436 — [PATCH 3.10 094/250] perf scripting: Avoid leaking the scripting_context variable

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

commit cf346d5bd4b9d61656df2f72565c9b354ef3ca0d upstream.

Both register_perl_scripting() and register_python_scripting() allocate
this variable, fix it by checking if it already was.

#1660437 — [PATCH 3.10 219/250] MIPS: KGDB: Use kernel context for sleeping threads

From: James Hogan <james.hogan@imgtec.com>

commit 162b270c664dca2e0944308e92f9fcc887151a72 upstream.

KGDB is a kernel debug stub and it can't be used to debug userland as it
can only safely access kernel memory.

On MIPS however KGDB has always got the register state of sleeping
processes from the userland register context at the beginning of the
kernel stack. This is meaningless for kernel threads (which never enter
userland), and for user threads it prevents the user seeing what it is
doing while in the kernel:

(gdb) info threads
  Id   Target Id         Frame
  ...
  3    Thread 2 (kthreadd) 0x0000000000000000 in ?? ()
  2    Thread 1 (init)   0x000000007705c4b4 in ?? ()
  1    Thread -2 (shadowCPU0) 0xffffffff8012524c in arch_kgdb_breakpoint () at arch/mips/kernel/kgdb.c:201

Get the register state instead from the (partial) kernel register
context stored in the task's thread_struct for resume() to restore. All
threads now correctly appear to be in context_switch():

(gdb) info threads

#1660439 — [PATCH 3.10 132/250] USB: serial: ark3116: fix register-accessor error handling

From: Johan Hovold <johan@kernel.org>

commit 9fef37d7cf170522fb354d6d0ea6de09b9b16678 upstream.

The current implementation failed to detect short transfers, something
which could lead to bits of the uninitialised heap transfer buffer
leaking to user space.

#1660441 — [PATCH 3.10 130/250] USB: serial: spcp8x5: fix modem-status handling

From: Johan Hovold <johan@kernel.org>

commit 5ed8d41023751bdd3546f2fe4118304357efe8d2 upstream.

Make sure to detect short control transfers and return zero on success
when retrieving the modem status.

This fixes the TIOCMGET implementation which since e1ed212d8593 ("USB:
spcp8x5: add proper modem-status support") has returned TIOCM_LE on
successful retrieval, and avoids leaking bits from the stack on short
transfers.

This also fixes the carrier-detect implementation which since the above
mentioned commit unconditionally has returned true.

#1660442 — [PATCH 3.10 227/250] ping: implement proper locking

From: Eric Dumazet <edumazet@google.com>

commit 43a6684519ab0a6c52024b5e25322476cabad893 upstream.

We got a report of yet another bug in ping

http://www.openwall.com/lists/oss-security/2017/03/24/6

->disconnect() is not called with socket lock held.

Fix this by acquiring ping rwlock earlier.

Set traffic class within sl_tclass_flowlabel when create iboe AH.
Without this the TOS value will be empty when running VLAN tagged
traffic, because the TOS value is taken from the traffic class in the

#1660447 — [PATCH 3.10 242/250] kvm: exclude ioeventfd from counting kvm_io_range limit

From: Amos Kong <akong@redhat.com>

commit 6ea34c9b78c10289846db0abeebd6b84d5aca084 upstream.

We can easily reach the 1000 limit by start VM with a couple
hundred I/O devices (multifunction=on). The hardcode limit
already been adjusted 3 times (6 ~ 200 ~ 300 ~ 1000).

In userspace, we already have maximum file descriptor to
limit ioeventfd count. But kvm_io_bus devices also are used
for pit, pic, ioapic, coalesced_mmio. They couldn't be limited
by maximum file descriptor.

Currently only ioeventfds take too much kvm_io_bus devices,
so just exclude it from counting kvm_io_range limit.

Also fixed one indent issue in kvm_host.h

#1660448 — [PATCH 3.10 222/250] tun: Fix TUN_PKT_STRIP setting

From: Herbert Xu <herbert@gondor.apana.org.au>

commit 2eb783c43e7cf807a45899c10ed556b6dc116625 upstream.

We set the flag TUN_PKT_STRIP if the user buffer provided is too
small to contain the entire packet plus meta-data.  However, this
has been broken ever since we added GSO meta-data.  VLAN acceleration
also has the same problem.

This patch fixes this by taking both into account when setting the
TUN_PKT_STRIP flag.

The fact that this has been broken for six years without anyone
realising means that nobody actually uses this flag.

drivers/scsi/mvsas/mv_94xx.c: In function 'mvs_94xx_command_active':
drivers/scsi/mvsas/mv_94xx.c:671:15: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context]

This was introduced when the mv_printk() statement got added, and leads
to the condition being ignored. This is probably harmless.

Changing '&&' to '&' makes the code look reasonable, as we check the
command bit before setting and printing it.

#1660451 — [PATCH 3.10 207/250] s390/decompressor: fix initrd corruption caused by bss clear

From: Marcelo Henrique Cerri <marcelo.cerri@canonical.com>

commit d82c0d12c92705ef468683c9b7a8298dd61ed191 upstream.

Reorder the operations in decompress_kernel() to ensure initrd is moved
to a safe location before the bss section is zeroed.

During decompression bss can overlap with the initrd and this can
corrupt the initrd contents depending on the size of the compressed
kernel (which affects where the initrd is placed by the bootloader) and
the size of the bss section of the decompressor.

Also use the correct initrd size when checking for overlaps with
parmblock.

#1660454 — [PATCH 3.10 161/250] MIPS: ip27: Disable qlge driver in defconfig

From: Arnd Bergmann <arnd@arndb.de>

commit b617649468390713db1515ea79fc772d2eb897a8 upstream.

One of the last remaining failures in kernelci.org is for a gcc bug:

drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: error: insn does not satisfy its constraints:
drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: internal compiler error: in extract_constrain_insn, at recog.c:2190

This is apparently broken in gcc-6 but fixed in gcc-7, and I cannot
reproduce the problem here. However, it is clear that ip27_defconfig
does not actually need this driver as the platform has only PCI-X but
not PCIe, and the qlge adapter in turn is PCIe-only.

The driver was originally enabled in 2010 along with lots of other
drivers.

#1660457 — [PATCH 3.10 228/250] USB: fix problems with duplicate endpoint addresses

From: Alan Stern <stern@rowland.harvard.edu>

commit 0a8fd1346254974c3a852338508e4a4cddbb35f1 upstream.

When checking a new device's descriptors, the USB core does not check
for duplicate endpoint addresses.  This can cause a problem when the
sysfs files for those endpoints are created; trying to create multiple
files with the same name will provoke a WARNING:

#1660458 — [PATCH 3.10 143/250] MIPS: Prevent unaligned accesses during stack unwinding

From: Paul Burton <paul.burton@imgtec.com>

commit a3552dace7d1d0cabf573e88fc3025cb90c4a601 upstream.

During stack unwinding we call a number of functions to determine what
type of instruction we're looking at. The union mips_instruction pointer
provided to them may be pointing at a 2 byte, but not 4 byte, aligned
address & we thus cannot directly access the 4 byte wide members of the
union mips_instruction. To avoid this is_ra_save_ins() copies the
required half-words of the microMIPS instruction to a correctly aligned
union mips_instruction on the stack, which it can then access safely.
The is_jump_ins() & is_sp_move_ins() functions do not correctly perform
this temporary copy, and instead attempt to directly dereference 4 byte
fields which may be misaligned and lead to an address exception.

Fix this by copying the instruction halfwords to a temporary union
mips_instruction in get_frame_info() such that we can provide a 4 byte
aligned union mips_instruction to the is_*_ins() functions and they do
not need to deal with misalignment themselves.

#1660460 — [PATCH 3.10 119/250] netlabel: out of bound access in cipso_v4_validate()

From: Eric Dumazet <edumazet@google.com>

commit d71b7896886345c53ef1d84bda2bc758554f5d61 upstream.

syzkaller found another out of bound access in ip_options_compile(),
or more exactly in cipso_v4_validate()

Fixes: 20e2a8648596 ("cipso: handle CIPSO options correctly when NetLabel is disabled")
Fixes: 446fda4f2682 ("[NetLabel]: CIPSOv4 engine")

#1660461 — [PATCH 3.10 065/250] hwmon: (ds620) Fix overflows seen when writing temperature limits

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

commit e36ce99ee0815d7919a7b589bfb66f3de50b6bc7 upstream.

Module test reports:

temp1_max: Suspected overflow: [160000 vs. 0]
temp1_min: Suspected overflow: [160000 vs. 0]

This is seen because the values passed when writing temperature limits
are unbound.

#1660462 — [PATCH 3.10 162/250] tracing: Add #undef to fix compile error

From: Rik van Riel <riel@redhat.com>

commit bf7165cfa23695c51998231c4efa080fe1d3548d upstream.

There are several trace include files that define TRACE_INCLUDE_FILE.

Include several of them in the same .c file (as I currently have in
some code I am working on), and the compile will blow up with a
"warning: "TRACE_INCLUDE_FILE" redefined #define TRACE_INCLUDE_FILE syscalls"

Every other include file in include/trace/events/ avoids that issue
by having a #undef TRACE_INCLUDE_FILE before the #define; syscalls.h
should have one, too.
