#1167431 — [PATCH 3.19.y-ckt 066/146] jbd2: fix r_count overflows leading to buffer overflow in journal recovery

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Darrick J. Wong" <darrick.wong@oracle.com>

commit e531d0bceb402e643a4499de40dd3fa39d8d2e43 upstream.

The journal revoke block recovery code does not check r_count for
sanity, which means that an evil value of r_count could result in
the kernel reading off the end of the revoke table and into whatever
garbage lies beyond.  This could crash the kernel, so fix that.

However, in testing this fix, I discovered that the code to write
out the revoke tables also was not correctly checking to see if the
block was full -- the current offset check is fine so long as the
revoke table space size is a multiple of the record size, but this
is not true when either journal_csum_v[23] are set.

#1167432 — [PATCH 3.19.y-ckt 046/146] xhci: gracefully handle xhci_irq dead device

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Joe Lawrence <joe.lawrence@stratus.com>

commit 948fa13504f80b9765d2b753691ab94c83a10341 upstream.

If the xHCI host controller has died (ie, device removed) or suffered
other serious fatal error (STS_FATAL), then xhci_irq should handle this
condition with IRQ_HANDLED instead of -ESHUTDOWN.

#1167433 — [PATCH 3.19.y-ckt 048/146] staging: gdm724x: Correction of variable usage after applying ALIGN()

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: =?UTF-8?q?S=C5=82awomir=20Demeszko?=

commit 892c89d5d7ffd1bb794fe54d86c0eef18d215fab upstream.

Fix regression introduced by commit <29ef8a53542a>. After it writing
AT commands to /dev/GCT-ATM0 is unsuccessful (no echo, no response)
and dmesg show "gdmtty: invalid payload : 1 16 f011".

Before that commit value of dummy_cnt was only a padding size. After using
ALIGN() this value is increased by its first argument. So the following
usage of this variable needs correction.

#1167435 — [PATCH 3.19.y-ckt 054/146] x86/vdso: Fix the x86 vdso2c tool includes

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tommi Kyntola <tommi.kyntola@gmail.com>

commit 0a4f59d6e09ef16fbb7d213cfa1bf472c7845fda upstream.

The build-time tool arch/x86/vdso/vdso2c.c includes <linux/elf.h>,
but cannot find it, unless the build host happens to provide it.

It should be reading the uapi linux/elf.h

This build regression came along with the vdso2c changes between
v3.15 and v3.16.

#1167436 — [PATCH 3.19.y-ckt 062/146] net: phy: micrel: Fix regression in kszphy_probe

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Niklas Cassel <niklas.cassel@axis.com>

commit bced870152161435cc59a53e77f3699f8e8f22ca upstream.

Don't do clock-mode-select if clk == NULL,
since when building without CONFIG_HAVE_CLK,
clk_get returns NULL and clk_get_rate returns 0.

Doing clock-mode-select in this cause causes kszphy_probe to
return -EINVAL and thus prevents the device from being probed.

The original code (before regression) would return 0
when building without CONFIG_HAVE_CLK.

KSZ8021/KSZ8031")

Most of kernel code assume that interface array in
struct usb_configuration is NULL terminated.

When gadget is composed with configfs configuration
structure may be reused for different functions set.

This bug happens because purge_configs_funcs() sets
only next_interface_id to 0. Interface array still
contains pointers to already freed interfaces. If in
second try we add less interfaces than earlier we
may access unallocated memory when trying to get
interface descriptors.

#1167438 — [PATCH 3.19.y-ckt 045/146] xhci: Solve full event ring by increasing TRBS_PER_SEGMENT to 256

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mathias Nyman <mathias.nyman@linux.intel.com>

commit 18cc2f4cbbaf825a4fedcf2d60fd388d291e0a38 upstream.

Our event ring consists of only one segment, and we risk filling
the event ring in case we get isoc transfers with short intervals
such as webcams that fill a TD every microframe (125us)

With 64 TRB segment size one usb camera could fill the event ring in 8ms.
A setup with several cameras and other devices can fill up the
event ring as it is shared between all devices.
This has occurred when uvcvideo queues 5 * 32TD URBs which then
get cancelled when the video mode changes. The cancelled URBs are returned
in the xhci interrupt context and blocks the interrupt handler from
handling the new events.

A full event ring will block xhci from scheduling traffic and affect all
devices conneted to the xhci, will see errors such as Missed Service
Intervals for isoc devices, and  and Split transaction errors for LS/FS
interrupt devices.

Increasing the TRB_PER_SEGMENT will also increase the default endpoint ring
size, which is welcome as for most isoc transfer we had to dynamically
expand the endpoint ring anyway to be able to queue the 5 * 32TDs uvcvideo
queues.

The default size used to be 64 TRBs per segment

#1167439 — [PATCH 3.19.y-ckt 028/146] rtlwifi: rtl8192cu: Fix kernel deadlock

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Larry Finger <Larry.Finger@lwfinger.net>

commit 414b7e3b9ce8b0577f613e656fdbc36b34b444dd upstream.

The USB mini-driver in rtlwifi, which is used by rtl8192cu, issues a call to
usb_control_msg() with a timeout value of 0. In some instances where the
interface is shutting down, this infinite wait results in a CPU deadlock. A
one second timeout fixes this problem without affecting any normal operations.

This bug is reported at https://bugzilla.novell.com/show_bug.cgi?id=927786.

#1167440 — [PATCH 3.19.y-ckt 059/146] RDMA/core: Fix for parsing netlink string attribute

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tatyana Nikolova <Tatyana.E.Nikolova@intel.com>

commit ec04847c0c5b471bab2dacceadfdb803a9d1a2ea upstream.

The string iwpm_ulib_name is recorded in a nlmsg as a netlink attribute.
Without this fix parsing of the nlmsg by the userspace port mapper service fails
because of unknown attribute length, causing the port mapper service not to
register the client, which has sent the nlmsg.

#1167441 — [PATCH 3.19.y-ckt 033/146] nfsd: fix the check for confirmed openowner in nfs4_preprocess_stateid_op

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christoph Hellwig <hch@lst.de>

commit ebe9cb3bb13e7b9b281969cd279ce70834f7500f upstream.

If we find a non-confirmed openowner we jump to exit the function, but do
not set an error value.  Fix this by factoring out a helper to do the
check and properly set the error from nfsd4_validate_stateid.

#1167443 — [PATCH 3.19.y-ckt 061/146] parisc,metag: Fix crashes due to stack randomization on stack-grows-upwards architectures

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Helge Deller <deller@gmx.de>

commit d045c77c1a69703143a36169c224429c48b9eecd upstream.

On architectures where the stack grows upwards (CONFIG_STACK_GROWSUP=y,
currently parisc and metag only) stack randomization sometimes leads to crashes
when the stack ulimit is set to lower values than STACK_RND_MASK (which is 8 MB
by default if not defined in arch-specific headers).

The problem is, that when the stack vm_area_struct is set up in fs/exec.c, the
additional space needed for the stack randomization (as defined by the value of
STACK_RND_MASK) was not taken into account yet and as such, when the stack
randomization code added a random offset to the stack start, the stack
effectively got smaller than what the user defined via rlimit_max(RLIMIT_STACK)
which then sometimes leads to out-of-stack situations and crashes.

This patch fixes it by adding the maximum possible amount of memory (based on
STACK_RND_MASK) which theoretically could be added by the stack randomization
code to the initial stack size. That way, the user-defined stack size is always
guaranteed to be at minimum what is defined via rlimit_max(RLIMIT_STACK).

This bug is currently not visible on the metag architecture, because on metag
STACK_RND_MASK is defined to 0 which effectively disables stack randomization.

The changes to fs/exec.c are inside an "#ifdef CONFIG_STACK_GROWSUP"
section, so it does not affect other platformws beside those where the
stack grows upwards (parisc and metag).

#1167444 — [PATCH 3.19.y-ckt 068/146] mm, numa: really disable NUMA balancing by default on single node machines

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mel Gorman <mgorman@suse.de>

commit b0dc2b9bb4ab782115b964310518ee0b17784277 upstream.

NUMA balancing is meant to be disabled by default on UMA machines but
the check is using nr_node_ids (highest node) instead of
num_online_nodes (online nodes).

The consequences are that a UMA machine with a node ID of 1 or higher
will enable NUMA balancing.  This will incur useless overhead due to
minor faults with the impact depending on the workload.  These are the
impact on the stats when running a kernel build on a single node machine
whose node ID happened to be 1:

  			       vanilla     patched
  NUMA base PTE updates          5113158           0
  NUMA huge PMD updates              643           0
  NUMA page range updates        5442374           0
  NUMA hint faults               2109622           0
  NUMA hint local faults         2109622           0
  NUMA hint local percent            100         100

commit b23f14302e86628625ac3982a6d23e35888755f2 upstream.

Information for packet type is in ieee80211_tx_info

band IEEE80211_BAND_5GHZ for PK_TYPE_11A.

IEEE80211_TX_RC_USE_CTS_PROTECT via tx_rate flags selects PK_TYPE_11GB

This ensures that the packet is always the right type.

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jeppe Ledet-Pedersen <jlp@gomspace.com>

commit 5793affe8c723ece8114b898ab9003c7d97f86d1 upstream.

Using IDR_SRR in RXFIFO_ID to test for the presence of data is only
valid for standard frames. For extended frames the bit is always 1 and
IDR_RTR should be used instead. This patch switches the check to use
CAN_RTR_FLAG which is correctly set when reading the ID.

The patch also changes the DW1/DW2 to be read unconditionally, since
this is necessary to remove the frame from the RXFIFO.

the loop of the allocation of memory of the FW monitor we
indeed free the pages, but don't NULL out the page variable
thus allowing for the possibility of setting the FW monitor

#1167448 — [PATCH 3.19.y-ckt 034/146] svcrpc: fix potential GSSX_ACCEPT_SEC_CONTEXT decoding failures

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Scott Mayhew <smayhew@redhat.com>

commit 9507271d960a1911a51683888837d75c171cd91f upstream.

In an environment where the KDC is running Active Directory, the
exported composite name field returned in the context could be large
enough to span a page boundary.  Attaching a scratch buffer to the
decoding xdr_stream helps deal with those cases.

The case where we saw this was actually due to behavior that's been
fixed in newer gss-proxy versions, but we're fixing it here too.

#1167450 — [PATCH 3.19.y-ckt 057/146] net: qca_spi: Fix possible race during probe

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

From: Stefan Wahren <stefan.wahren@i2se.com>

commit 268be0f7a7d9b3644bcb99568efba13cb208b627 upstream.

Registering the netdev before setting the priv data is unsafe.
So fix this possible race by setting the priv data first.
