2015-06-12netfilter: bridge: refactor frag_max_sizeBernhard Thaler
Currently frag_max_size is member of br_input_skb_cb and copied back and forth using IPCB(skb) and BR_INPUT_SKB_CB(skb) each time it is changed or used. Attach frag_max_size to nf_bridge_info and set value in pre_routing and forward functions. Use its value in forward and xmit functions.

2015-06-12netfilter: bridge: detect NAT66 correctly and change MAC addressBernhard Thaler
IPv4 iptables allows to REDIRECT/DNAT/SNAT any traffic over a bridge. e.g. REDIRECT $ sysctl -w net.bridge.bridge-nf-call-iptables=1 $ iptables -t nat -A PREROUTING -p tcp -m tcp --dport 8080 \ -j REDIRECT --to-ports 81 This does not work with ip6tables on a bridge in NAT66 scenario because the REDIRECT/DNAT/SNAT is not correctly detected. The bridge pre-routing (finish) netfilter hook has to check for a possible redirect and then fix the destination mac address. This allows to use the ip6tables rules for local REDIRECT/DNAT/SNAT REDIRECT similar to the IPv4 iptables version. e.g. REDIRECT $ sysctl -w net.bridge.bridge-nf-call-ip6tables=1 $ ip6tables -t nat -A PREROUTING -p tcp -m tcp --dport 8080 \ -j REDIRECT --to-ports 81 This patch makes it possible to use IPv6 NAT66 on a bridge. It was tested on a bridge with two interfaces using SNAT/DNAT NAT66 rules.

2015-06-12netfilter: conntrack: warn the user if there is a better helper to useMarcelo Ricardo Leitner
After db29a9508a92 ("netfilter: conntrack: disable generic tracking for known protocols"), if the specific helper is built but not loaded (a standard for most distributions) systems with a restrictive firewall but weak configuration regarding netfilter modules to load, will silently stop working. This patch then puts a warning message so the sysadmin knows where to start looking into. It's a pr_warn_once regardless of protocol itself but it should be enough to give a hint on where to look.

2015-06-12iommu/vt-d: Only enable extended context tables if PASID is supportedDavid Woodhouse
Although the extended tables are theoretically a completely orthogonal feature to PASID and anything else that *uses* the newly-available bits, some of the early hardware has problems even when all we do is enable them and use only the same bits that were in the old context tables. For now, there's no motivation to support extended tables unless we're going to use PASID support to do SVM. So just don't use them unless PASID support is advertised too. Also add a command-line bailout just in case later chips also have issues. The equivalent problem for PASID support has already been fixed with the upcoming VT-d spec update and commit bd00c606a ("iommu/vt-d: Change PASID support to bit 40 of Extended Capability Register"), because the problematic platforms use the old definition of the PASID-capable bit, which is now marked as reserved and meaningless. So with this change, we'll magically start using ECS again only when we see the new hardware advertising "hey, we have PASID support and we actually tested it this time" on bit 40. The VT-d hardware architect has promised that we are not going to have any reason to support ECS *without* PASID any time soon, and he'll make sure he checks with us before changing that. In the future, if hypothetical new features also use new bits in the context tables and can be seen on implementations *without* PASID support, we might need to add their feature bits to the ecs_enabled() macro.

2015-06-12md: make sure MD_RECOVERY_DONE is clear before starting recovery/resyncNeilBrown
MD_RECOVERY_DONE is normally cleared by md_check_recovery after a resync etc finished. However it is possible for raid5_start_reshape to race and start a reshape before MD_RECOVERY_DONE is cleared. This can lean to multiple reshapes running at the same time, which isn't good. To make sure it is cleared before starting a reshape, and also clear it when reaping a thread, just to be safe.

2015-06-12md: Close race when setting 'action' to 'idle'.NeilBrown
Checking ->sync_thread without holding the mddev_lock() isn't really safe, even after flushing the workqueue which ensures md_start_sync() has been run. While this code is waiting for the lock, md_check_recovery could reap the thread itself, and then start another thread (e.g. recovery might finish, then reshape starts). When this thread gets the lock md_start_sync() hasn't run so it doesn't get reaped, but MD_RECOVERY_RUNNING gets cleared. This allows two threads to start which leads to confusion. So don't both if MD_RECOVERY_RUNNING isn't set, but if it is do the flush and the test and the reap all under the mddev_lock to avoid any race with md_check_recovery.

2015-06-12dmaengine: Fix choppy sound because of unimplemented resumeKrzysztof Kozlowski
Some drivers implement only pause operation (no resuming). Example is pl330 where pause is needed for getting residuum. pl330 does not support resume operation, transfer must be stopped after pause. However for slaves this is exposed always as "pause and resume" which introduces subtle errors on Odroid U3 board (Exynos4412 with pl330). After adding pause function to pl330 driver the audio playback (utilizing DMA) gets choppy after some time (approximately 24 hours). Fix this by exposing "cmd_pause" if and only if pause and resume are implemented.

The IRTE (Interrupt Remapping Table Entry) is either an entry for remapped or for posted interrupts. The hardware distiguishes between remapped and posted entries by bit 15 in the low 64 bit of the IRTE. If cleared the entry is remapped, if set it's posted. The entries have common fields and dependent on the posted bit fields with different meanings. Extend struct irte to handle the differences between remap and posted mode by having three structs in the unions: - Shared - Remapped - Posted Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Feng Wu <feng.wu@intel.com> Acked-by: Joerg Roedel <joro@8bytes.org> Cc: jiang.liu@linux.intel.com Cc: iommu@lists.linux-foundation.org Cc: dwmw2@infradead.org Link: http://lkml.kernel.org/r/1433827237-3382-3-git-send-email-feng.wu@intel.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2015-06-12pwm: atmel: Fix incorrect CDTY value after disablingAlexandre Belloni
pwm-leds calls .config() and .disable() in a row. This exhibits that it may happen that the channel gets disabled before CDTY has been updated with CUPD. The issue gets quite worse with long periods. So, ensure that at least one period has past before disabling the channel by polling ISR.
