Nikolay Aleksandrov says: ==================== bridge: vlan: failure path and comment fixes This is a set from Ido which takes care of one failure path error in nbp_vlan_init (patch 1) and a few comment errors (patch 2). I must admit I didn't expect the port init continues after a vlan init failure but should've checked to make sure. Thanks to Ido for catching these! ==================== Signed-off-by: David S.

2015-11-02bridge: vlan: Use correct flag name in commentIdo Schimmel
The flag used to indicate if a VLAN should be used for filtering - as opposed to context only - on the bridge itself (e.g. br0) is called 'brentry' and not 'brvlan'.

2015-11-02bridge: vlan: Prevent possible use-after-freeIdo Schimmel
When adding a port to a bridge we initialize VLAN filtering on it. We do not bail out in case an error occurred in nbp_vlan_init, as it can be used as a non VLAN filtering bridge. However, if VLAN filtering is required and an error occurred in nbp_vlan_init, we should set vlgrp to NULL, so that VLAN filtering functions (e.g. br_vlan_find, br_get_pvid) will know the struct is invalid and will not try to access it.

2015-11-02tcp/dccp: fix ireq->pktopts raceEric Dumazet
IPv6 request sockets store a pointer to skb containing the SYN packet to be able to transfer it to full blown socket when 3WHS is done (ireq->pktopts -> np->pktoptions) As explained in commit 5e0724d027f0 ("tcp/dccp: fix hashdance race for passive sessions"), we must transfer the skb only if we won the hashdance race, if multiple cpus receive the 'ack' packet completing 3WHS at the same time.

2015-11-02RDS: convert bind hash table to re-sizable hashtablesantosh.shilimkar@oracle.com
To further improve the RDS connection scalabilty on massive systems where number of sockets grows into tens of thousands of sockets, there is a need of larger bind hashtable. Pre-allocated 8K or 16K table is not very flexible in terms of memory utilisation. The rhashtable infrastructure gives us the flexibility to grow the hashtbable based on use and also comes up with inbuilt efficient bucket(chain) handling.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the big bulk of pin control changes for the v4.4 kernel development cycle. Development pace is high in pin control again this merge window. 28 contributors, 83 patches. It hits a few sites outside the pin control subsystem: - Device tree bindings in Documentation (as usual) - MAINTAINERS - drivers/base/* for the "init" state handling by Doug Anderson. This has been ACKed by Greg. - drivers/usb/renesas_usbhs/rcar2.c, for a dependent Renesas change in the USB subsystem. This has been ACKed by both Greg and Felipe. - arch/arm/boot/dts/sama5d2.dtsi - this should ideally have gone through the ARM SoC tree but ended up here. This time I am using Geert Uytterhoeven as submaintainer for SH PFC since the are three-four people working in parallel with new Renesas ASICs. Summary of changes: Infrastructure: - Doug Anderson wrote a patch adding an "init" state different from the "default" state for pin control state handling in the core framework. This is applied before the driver's probe() call if defined and takes precedence over "default". If both are defined, "init" will be applied *before* probe() and "default" will be applied *after* probe(). Significant subdriver improvements: - SH PFC is switched to getting GPIO ranges from the device tree ranges property on DT platforms. - Got rid of CONFIG_ARCH_SHMOBILE_LEGACY, we are all modernized. - Got rid of SH PFC hardcoded IRQ numbers. - Allwinner sunxi external interrupt through the "r" controller. - Moved the Cygnus driver to use DT-provided GPIO ranges. New drivers: - Atmel PIO4 pin controller for the SAMA4D2 family New subdrivers: - Rockchip RK3036 subdriver - Renesas SH PFC R8A7795 subdriver - Allwinner sunxi A83T PIO subdriver - Freescale i.MX7d iomux lpsr subdriver - Marvell Berlin BG4CT subdriver - SiRF Atlas 7 step B SoC subdriver - Intel Broxton SoC subdriver Apart from this, the usual slew if syntactic and semantic fixes" * tag 'pinctrl-v4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (81 commits) pinctrl: pinconf: remove needless loop pinctrl: uniphier: guard uniphier directory with CONFIG_PINCTRL_UNIPHIER pinctrl: zynq: fix UTF-8 errors pinctrl: zynq: Initialize early pinctrl: at91: add missing of_node_put pinctrl: tegra-xusb: Correct lane mux options pinctrl: intel: Add Intel Broxton pin controller support pinctrl: intel: Allow requesting pins which are in ACPI mode as GPIOs pinctrl: intel: Add support for multiple GPIO chips sharing the interrupt drivers/pinctrl: Add the concept of an "init" state pinctrl: uniphier: set input-enable before pin-muxing pinctrl: cygnus: Add new compatible string for gpio controller driver pinctrl: cygnus: Remove GPIO to Pinctrl pin mapping from driver pinctrl: cygnus: Optional DT property to support pin mappings pinctrl: sunxi: Add irq pinmuxing to sun6i "r" pincontroller pinctrl: sunxi: Fix irq_of_xlate for the r_pio pinctrl block pinctrl: sh-pfc: Remove obsolete r8a7778 platform_device_id entry pinctrl: sh-pfc: Remove obsolete r8a7779 platform_device_id entry pinctrl: sh-pfc: Stop including <linux/platform_data/gpio-rcar.h> usb: renesas_usbhs: Remove unneeded #include <linux/platform_data/gpio-rcar.h> ...

Javier Martinez Canillas says: ==================== net: encx24j600: Fix SPI driver module autoload Recently I've been trying to fix module autoloading for all SPI drivers and found that the encx24j600 driver does not fill module alias information due missing a MODULE_DEVICE_TABLE() so module autload won't work and the driver Kconfig symbol is tristate which means the driver can be built as a module.

2015-11-02net: encx24j600: Fix SPI id table definitionJavier Martinez Canillas
A driver's SPI id table is expected to be an array of struct spi_device_id that ends with a zero-initialized sentinel entry. But this driver defines the table as a single struct spi_device_id and sets .id_table to a pointer to this struct. But spi_match_id() has a loop that iterates while the struct spi_device_id .name[0] is not NULL, so not having a sentinel can cause a NULL pointer deference error. This patch defines the SPI id table correctly as all other SPI drivers do. Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-11-02ipv4: use l4 hash for locally generated multipath flowsPaolo Abeni
This patch changes how the multipath hash is computed for locally generated flows: now the hash comprises l4 information. This allows better utilization of the available paths when the existing flows have the same source IP and the same destination IP: with l3 hash, even when multiple connections are in place simultaneously, a single path will be used, while with l4 hash we can use all the available paths. v2 changes: - use get_hash_from_flowi4() instead of implementing just another l4 hash function Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.

This is because: 1) We cannot see these records since ring_buffer record is off at that moment. 2) If tracing is off and benchmark tracepoint is enabled, the time tracepoint takes is fewer than the same situation when tracing is on, since the tracepoints need to be wrote into ring_buffer, it would take more time. If turn on tracing at this moment, the average and standard deviation cannot exactly present the time that tracepoints take to write data into ring_buffer.

2015-11-02recordmcount: x86: Assign a meaningful value to rel_type_nopLi Bin
Although, the default value of rel_type_nop is zero, and the value of R_386_NONE/R_X86_64_NONE is zero too, but it should be assigned a meaningful value explicitly, otherwise it looks confused. Assign R_386_NONE to rel_type_nop for 386, assign R_X86_64_NONE to rel_type_nop for x86_64.

set_event_pid For the case where pids are already in set_event_pid, and one is added or removed then each CPU should be checked to make sure that the new or old pid is on or not on a CPU. For example: # echo 123 >> set_event_pid or # echo '!123' >> set_event_pid Link: http://lkml.kernel.org/r/20151030061643.GA19480@cac Suggested-by: Jiaxing Wang <hello.wjx@gmail.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

2015-11-02ALSA: hda - Fix lost 4k BDL boundary workaroundTakashi Iwai
During the migration to HDA core code, we lost the workaround for 4k BDL boundary. The flag exists in the new hdac_bus, but it's never set. This resulted in the sudden sound stall on some controllers that require this workaround like Creative Recon3D. This patch fixes the issue by setting the flag for such controllers properly.
