The ksz884x driver does receive processing in a custom tasklet, and seems to be assuming that since it takes its private interface spinlock with spin_lock_irq(), it won't be running concurrently with its own interrupt handler, as it cannot be preempted by it, but since its interrupt handler doesn't do any locking whatsoever, the receive processing tasklet and interrupt handler can end up running concurrently on different CPUs. As a result of this, the ksz884x receive path ends up locking up fairly easily, when the receive processing tasklet's reenabling of receive interrupts (due to it being done with polling the receive ring) races with the interrupt handler's disabling of receive interrupts (due to a new receive interrupt coming in) resulting in the receive interrupt being masked but the receive processing tasklet not being scheduled. Fix this by making the ksz884x interrupt handler take its private interface spinlock. This requires upgrading the spin_lock() in the transmit cleanup tasklet to a spin_lock_irq(), as otherwise the IRQ handler can preempt transmit cleanup and deadlock the system, but with those two changes, no more receive lockups have been observed.

Beside imx6q, the kernel built from imx_v6_v7_defconfig is also supposed to be running on other IMX SoCs that do not have the PTP block. Before fec driver gets fixed to run-time detect target hardware rather than conditional compiling with #ifdef CONFIG_FEC_PTP, let's give it a quick fix in Kconfig to forbid FEC_PTP on those IMX SoCs that do not support PTP.

The RX CQ can report completions with invalid frag_idx when the RXQ that was *previously* using it, was not cleaned up properly. This hits a BUG_ON() in be2net. When completion coalescing is enabled on a CQ, an explicit CQ-notify (with rearm) is needed for each compl, to flush partially coalesced CQ entries that are pending DMA. In be_close(), this fix now notifies CQ for each compl, waits explicitly for the flush compl to arrive and complains if it doesn't arrive. Also renaming be_crit_error() to be_hw_error() as it's the more appropriate name and to convey that we don't wait for the flush compl only when a HW error has occurred. Signed-off-by:

In be_close(), be_eq_clean() must be called after all RX/TX/MCC queues have been cleaned to ensure that any events caused while cleaning up completions are notified/acked. Not clearing all events can cause upredictable behaviour when RX rings are re-created in the subsequent be_open(). Signed-off-by:

In commit 'mac80211: support radiotap vendor namespace RX data' new fields were added to 'struct ieee80211_rx_status' and those fileds must be zeroed. However the rt2x00 driver stores driver specific data in the cb array of the rx skbs, so the fields might contain garbage and this can cause unexpected behaviour. The rt2x00 driver from the compat-wireless-2012-12-01 tarball caused the following warning: WARNING: at /devel/ramips/build_dir/target-mipsel_r2_uClibc-0.9.33.2/linux-ramips_rt305x/ compat-wireless-2012-12-01/net/mac80211/rx.c:115 ieee80211_rx_irqsafe+0x274/0xbcc [mac80211]() Modules linked in: dwc_otg ledtrig_usbdev nf_nat_irc nf_nat_ftp nf_conntrack_irc nf_conntrack_ftp ipt_MASQUERADE iptable_nat nf_nat pppoe xt_conntrack xt_CT xt_NOTRACK iptable_raw xt_state nf_conntrack_ipv4 nf_defrag_ipv4 nf_conntrack pppox ipt_REJECT xt_TCPMSS xt_comment xt_multiport xt_mac xt_limit iptable_mangle iptable_filter ip_tables xt_tcpudp x_tables ppp_async ppp_generic slhc rt2800pci(O) rt2800lib(O) rt2x00soc(O) rt2x00pci(O) rt2x00lib(O) mac80211(O) usbcore usb_common nls_base crc_itu_t crc_ccitt eeprom_93cx6 cfg80211(O) compat(O) arc4 aes_generic crypto_blkcipher cryptomgr aead crypto_hash crypto_algapi leds_gpio button_hotplug(O) gpio_keys_polled input_polldev input_core Call Trace: [<801e96b4>] dump_stack+0x8/0x34 [<80010a9c>] warn_slowpath_common+0x78/0xa4 [<80010ae0>] warn_slowpath_null+0x18/0x24 [<80a9710c>] ieee80211_rx_irqsafe+0x274/0xbcc [mac80211] The patch ensures that each field gets initialized with zeroes.

Recently I posted commit 3c68198e which made selection of the cookie hmac algorithm selectable. This is all well and good, but Linus noted that it changes the default config: http://marc.info/?l=linux-netdev&m=135536629004808&w=2 I've modified the sctp Kconfig file to reflect the recommended way of making this choice, using the thermal driver example specified, and brought the defaults back into line with the way they were prior to my origional patch Also, on Linus' suggestion, re-adding ability to select default 'none' hmac algorithm, so we don't needlessly bloat the kernel by forcing a non-none default. This also led me to note that we won't honor the default none condition properly because of how sctp_net_init is encoded. Fix that up as well. Tested by myself (allbeit fairly quickly). All configuration combinations seems to work soundly. Signed-off-by:

Additionally, things like xfrm, memcg, cookie_values,... may have been initialized. We have to free them properly. This is fixed by forcing a call to tcp_done(), ending up in inet_csk_destroy_sock, doing the final sock_put(). tcp_done() is necessary, because it ends up doing all the cleanup on xfrm, memcg, cookie_values, xfrm,... Before calling tcp_done, we have to set the socket to SOCK_DEAD, to force it entering inet_csk_destroy_sock. To avoid the warning in inet_csk_destroy_sock, inet_num has to be set to 0. As inet_csk_destroy_sock does a dec on orphan_count, we first have to increase it. Calling tcp_done() allows us to remove the calls to tcp_clear_xmit_timer() and tcp_cleanup_congestion_control(). A similar approach is taken for dccp by calling dccp_done(). This is in the kernel since 093d2823 (tproxy: fix hash locking issue when using port redirection in __inet_inherit_port()), thus since version >= 2.6.37.

The current multiqueue API is ambigious which may confuse both user and LSM to do things correctly: - Both TUNSETIFF and TUNSETQUEUE could be used to create the queues of a tuntap device. - TUNSETQUEUE were used to disable and enable a specific queue of the device. But since the state of tuntap were completely removed from the queue, it could be used to attach to another device (there's no such kind of requirement currently, and it needs new kind of LSM policy. - TUNSETQUEUE could be used to attach to a persistent device without any queues. This kind of attching bypass the necessary checking during TUNSETIFF and may lead unexpected result. So this patch tries to make a cleaner and simpler API by: - Only allow TUNSETIFF to create queues. - TUNSETQUEUE could be only used to disable and enabled the queues of a device, and the state of the tuntap device were not detachd from the queues when it was disabled, so TUNSETQUEUE could be only used after TUNSETIFF and with the same device. This is done by introducing a list which keeps track of all queues which were disabled. The queue would be moved between this list and tfiles[] array when it was enabled/disabled. A pointer of the tun_struct were also introdued to track the device it belongs to when it was disabled. After the change, the isolation between management and application could be done through: TUNSETIFF were only called by management software and TUNSETQUEUE were only called by application.For LSM/SELinux, the things left is to do proper check during tun_set_queue() if needed.

This reverts commit f269ae04. It turns out it causes a very noticeable interactivity regression with CONFIG_SCHED_AUTOGROUP (test-case: "make -j32" of the kernel in a terminal window, while scrolling in a browser - the autogrouping means that the two end up in separate cgroups, and the browser should be smooth as silk despite the high load). Says Paul Turner: "It seems that the update-throttling on the wake-side is reducing the interactive tasks' ability to preempt. While I suspect the right longer term answer here is force these updates only in the cross-cgroup case; this is less trivial. For this release I believe the right answer is either going to be a revert or restore the updates on the enqueue-side." Reported-by:

The new features to note are: - Common code for describing GPIO CS lines in the device tree - Remove the SPI_BUFSIZ limitation on spi_write_the_read() - core spi ensures bits_per_word is set correctly - SPARC can now use SPI" * tag 'spi-for-linus' of git://git.secretlab.ca/git/linux-2.6: (36 commits) spi/sparc: Allow of_register_spi_devices for sparc spi: Remove HOTPLUG section attributes spi: Add support for specifying 3-wire mode via device tree spi: Fix comparison of different integer types spi/orion: Add SPI_CHPA and SPI_CPOL support to kirkwood driver. spi/sh: Add SH Mobile series as dependency to MSIOF controller spi/sh-msiof: Remove unneeded clock name spi: Remove SPI_BUFSIZ restriction on spi_write_then_read() spi/stmp: remove obsolete driver spi/clps711x: New SPI master driver spi: omap2-mcspi: remove duplicate inclusion of linux/err.h spi: omap2-mcspi: Fix the redifine warning spi/sh-hspi: add CS manual control support of_spi: add generic binding support to specify cs gpio spi: omap2-mcspi: remove duplicated include from spi-omap2-mcspi.c spi/bitbang: (cosmetic) simplify list manipulation spi/bitbang: avoid needless loop flow manipulations spi/omap: fix D0/D1 direction confusion spi: tegra: add spi driver for sflash controller spi: Dont call master->setup if not populated ...

For direct (and offset) mounts, if an automounted mount is manually umounted the trigger mount dentry can appear non-empty causing it to not trigger mounts. This can also happen if there is a file handle leak in a user space automounting application. This happens because, when a ioctl control file handle is opened on the mount, a cursor dentry is created which causes list_empty() to see the dentry as non-empty. Since there is a case where listing the directory of these dentrys is needed, the use of dcache_dir_*() functions for .open() and .release() is needed. Consequently simple_empty() must be used instead of list_empty() when checking for an empty directory. Signed-off-by:
