Since commit b0e9a30d ("bridge: Add vlan id to multicast groups") there's a check in br_ip_equal() for a matching vlan id, but the mdb functions were not modified to use (or at least zero it) so when an entry was added it would have a garbage vlan id (from the local br_ip variable in __br_mdb_add/del) and this would prevent it from being matched and also deleted. So zero out the whole local ip var to protect ourselves from future changes and also to fix the current bug, since there's no vlan id support in the mdb uapi - use always vlan id 0. Example before patch: root@debian:~# bridge mdb add dev br0 port eth1 grp 239.0.0.1 permanent root@debian:~# bridge mdb dev br0 port eth1 grp 239.0.0.1 permanent root@debian:~# bridge mdb del dev br0 port eth1 grp 239.0.0.1 permanent RTNETLINK answers: Invalid argument After patch: root@debian:~# bridge mdb add dev br0 port eth1 grp 239.0.0.1 permanent root@debian:~# bridge mdb dev br0 port eth1 grp 239.0.0.1 permanent root@debian:~# bridge mdb del dev br0 port eth1 grp 239.0.0.1 permanent root@debian:~# bridge mdb Signed-off-by:

When cpsw's number of slave is set to 1 in device tree and while accessing second slave ndev and priv in cpsw_tx_interrupt(), there is a kernel crash. This is due to cpsw_get_slave_priv() not verifying number of slaves while retriving netdev priv and returns a invalid memory region. Fixing the issue by introducing number of slave check in cpsw_get_slave_priv() and cpsw_get_slave_ndev().

Calling connect() with an AF_TIPC socket would trigger a series of error messages from SELinux along the lines of: SELinux: Invalid class 0 type=AVC msg=audit(1434126658.487:34500): avc: denied { <unprintable> } for pid=292 comm="kworker/u16:5" scontext=system_u:system_r:kernel_t:s0 tcontext=system_u:object_r:unlabeled_t:s0 tclass=<unprintable> permissive=0 This was due to a failure to initialize the security state of the new connection sock by the tipc code, leaving it with junk in the security class field and an unlabeled secid. Add a call to security_sk_clone() to inherit the security state from the parent socket. Reported-by:Tim Shearer <tim.shearer@overturenetworks.com> Signed-off-by:

Some versions of MCFW do not support the MC_CMD_VADAPTOR_SET_MAC command, and ENOSYS will be returned. If the PF created its own vport, the function's datapath must be stopped and the vport can be reconfigured to reflect the new MAC address. If the MCFW created the vport for the PF (which is the case when the nic_data->vport_mac is blank), nothing further needs to be done as the vport is not under the control of the PF. This only applies to PFs because the MCFW in question does not support VFs. Signed-off-by:

Re-organize the structure of error handling to avoid having to duplicate the netif_err() around the ifdefs. The only change to the behaviour of the error-handling is that the PF's data structure to record VF details should only be updated if the original command succeeded. Signed-off-by:

When "primary_reselect" is set to "failure", primary interface should not become active until current active slave is down. But if we set first member of bond device as a "primary" interface and "primary_reselect" is set to "failure" then whenever primary interface's link get back(up) it become active slave even if current active slave is still up. With this patch, "bond_find_best_slave" will not traverse members if primary interface is not candidate for failover/reselection and current active slave is still up. Signed-off-by:

Frag needed should be sent only if the inner header asked to not fragment. Currently fragmentation is broken if the tunnel has df set, but df was not asked in the original packet. The tunnel's df needs to be still checked to update internally the pmtu cache. Commit 23a3647b broke it, and this commit fixes the ipv4 df check back to the way it was.

Jason Gunthorpe reported that since commit c02db8c6 ("rtnetlink: make SR-IOV VF interface symmetric"), we don't verify IFLA_VF_INFO attributes anymore with respect to their policy, that is, ifla_vfinfo_policy[]. Before, they were part of ifla_policy[], but they have been nested since placed under IFLA_VFINFO_LIST, that contains the attribute IFLA_VF_INFO, which is another nested attribute for the actual VF attributes such as IFLA_VF_MAC, IFLA_VF_VLAN, etc. Despite the policy being split out from ifla_policy[] in this commit, it's never applied anywhere. nla_for_each_nested() only does basic nla_ok() testing for struct nlattr, but it doesn't know about the data context and their requirements. Fix, on top of Jason's initial work, does 1) parsing of the attributes with the right policy, and 2) using the resulting parsed attribute table from 1) instead of the nla_for_each_nested() loop (just like we used to do when still part of ifla_policy[]).

When a switch is attached to the mdio bus, the mdio bus can be used while the interface is not open. If the IPG clock is not enabled, MDIO reads/writes will simply time out. Add support for runtime PM to control this clock. Enable/disable this clock using runtime PM, with open()/close() and mdio read()/write() function triggering runtime PM operations. Since PM is optional, the IPG clock is enabled at probe and is no longer modified by fec_enet_clk_enable(), thus if PM is not enabled in the kernel, it is guaranteed the clock is running when MDIO operations are performed.

When running a kernel configured with CONFIG_DMA_API_DEBUG=y a warning is issued: DMA-API: device driver tries to sync DMA memory it has not allocated This warning is the result of mapping the full range of the Rx buffer pages allocated and then performing a dma_sync_single_for_cpu against a calculated DMA address. The proper thing to do is to use the dma_sync_single_range_for_cpu with a base DMA address and an offset. Reported-by:

If rhashtable_walk_next detects a resize operation in progress, it jumps to the new table and continues walking that one. But it misses to drop the reference to it's current item, leading it to continue traversing the new table's bucket in which the current item is sorted into, and after reaching that bucket's end continues traversing the new table's second bucket instead of the first one, thereby potentially missing items. This fixes the rhashtable runtime test for me. Bug probably introduced by Herbert Xu's patch eddee5ba ("rhashtable: Fix walker behaviour during rehash") although not explicitly tested.

Part of commit 49aa284fe64c4c1 ("cxgb4: Add support for devlog") change introduced a real bug where the Device Log Sequence Numbers are no longer being converted from firmware Big-Endian to local CPU-Endian format. This patch moves all of the translation into the devlog_show() routine. The only endianness code now in devlog_open() is the small loop to find the earliest (lowest Sequence Number) Device Log entry in the circular buffer.

After the change, a copy of MLD packet goes through ip6_mr_input, causing MRT6MSG_NOCACHE message to be generated to user space. Make MLD packet only processed locally.

Johan Hedberg says: ==================== pull request: bluetooth 2015-07-02 A couple of regressions crept in because of a patch to use proper list APIs rather than manually reading & writing the next/prev pointers (commit 835a6a2f). Turns out this was masking a few bugs: a missing INIT_LIST_HEAD() call and incorrectly using list_del() rather than list_del_init(). The two patches in this set fix these, and it'd be nice they could still make it to 4.2-rc1 to avoid new bug reports from users. Please let me know if there are any issues pulling. Thanks. ==================== Signed-off-by:

In enic_poll, we clean tx and rx queues, when low latency busy socket polling is happening, enic_poll will only clean tx queue. After cleaning tx, it should return total budget for re-poll. There is a small window between vnic_intr_unmask() and enic_poll_unlock_napi(). In this window if an irq occurs and napi is scheduled on different cpu, it tries to acquire enic_poll_lock_napi() and fails. Unlock napi_poll before unmasking the interrupt. v2: Do not change tx wonk done behaviour. Consider only rx work done for completing napi. Signed-off-by:

Pull init.h/module.h fragility fixes from Paul Gortmaker: "Fixup various init.h misuses that are fragile wrt code moving to module.h What started as a removal of no longer required include <linux/init.h> due to the earlier __cpuinit and __devinit removal led to the observation that some module specfic support was living in init.h itself, thus preventing the full removal from introducing compile regressions. This series includes a few final fixups needed prior to the relocation of the modular init code from <init.h> to <module.h>. These are things that weren't easily categorized into any of the other previous series categories already requested for pull. That said, each fixup branch (including this one) is independent and there are no ordering constraints. Only the final code relocation (which is NOT in this pull) requires that all my cleanup branches be merged first" * tag 'module-misc-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: tile: add init.h to usb.c to avoid compile failure arm: fix implicit #include <linux/init.h> in entry asm. x86: replace __init_or_module with __init in non-modular vsmp_64.c

Merge tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Pull module_platform_driver replacement from Paul Gortmaker: "Replace module_platform_driver with builtin_platform driver in non modules. We see an increasing number of non-modular drivers using modular_driver() type register functions. There are several downsides to letting this continue unchecked: - The code can appear modular to a reader of the code, and they won't know if the code really is modular without checking the Makefile and Kconfig to see if compilation is governed by a bool or tristate. - Coders of drivers may be tempted to code up an __exit function that is never used, just in order to satisfy the required three args of the modular registration function. - Non-modular code ends up including the <module.h> which increases CPP overhead that they don't need. - It hinders us from performing better separation of the module init code and the generic init code. So here we introduce similar macros for builtin drivers. Then we convert builtin drivers (controlled by a bool Kconfig) by making the following type of mapping: module_platform_driver() ---> builtin_platform_driver() module_platform_driver_probe() ---> builtin_platform_driver_probe(). The set of drivers that are converted here are just the ones that showed up as relying on an implicit include of <module.h> during a pending header cleanup. So we convert them here vs adding an include of <module.h> to non-modular code to avoid compile fails. Additonal conversions can be done asynchronously at any time. Once again, an unused module_exit function that is removed here appears in the diffstat as an outlier wrt all the other changes" * tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: drivers/clk: convert sunxi/clk-mod0.c to use builtin_platform_driver drivers/power: Convert non-modular syscon-reboot to use builtin_platform_driver drivers/soc: Convert non-modular soc-realview to use builtin_platform_driver drivers/soc: Convert non-modular tegra/pmc to use builtin_platform_driver drivers/cpufreq: Convert non-modular s5pv210-cpufreq.c to use builtin_platform_driver drivers/cpuidle: Convert non-modular drivers to use builtin_platform_driver drivers/platform: Convert non-modular pdev_bus to use builtin_platform_driver platform_device: better support builtin boilerplate avoidance

Merge tag 'module_init-alternate_initcall-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Pull module_init replacement part two from Paul Gortmaker: "Replace module_init with appropriate alternate initcall in non modules. This series converts non-modular code that is using the module_init() call to hook itself into the system to instead use one of our alternate priority initcalls. Unlike the previous series that used device_initcall and hence was a runtime no-op, these commits change to one of the alternate initcalls, because (a) we have them and (b) it seems like the right thing to do. For example, it would seem logical to use arch_initcall for arch specific setup code and fs_initcall for filesystem setup code. This does mean however, that changes in the init ordering will be taking place, and so there is a small risk that some kind of implicit init ordering issue may lie uncovered. But I think it is still better to give these ones sensible priorities than to just assign them all to device_initcall in order to exactly preserve the old ordering. Thad said, we have already made similar changes in core kernel code in commit c96d6660 ("kernel: audit/fix non-modular users of module_init in core code") without any regressions reported, so this type of change isn't without precedent. It has also got the same local testing and linux-next coverage as all the other pull requests that I'm sending for this merge window have got.

This series of commits converts non-modular code that is using the module_init() call to hook itself into the system to instead use device_initcall(). The conversion is a runtime no-op, since module_init actually becomes __initcall in the non-modular case, and that in turn gets mapped onto device_initcall.

We fix them up now, so that we can decouple some of the module related init code from the core init code in the future.

Pull __cpuinit removal from Paul Gortmaker: "Remove __cpuinit macros and users. We removed the __cpuinit stuff in 3.11-rc1 with commit 22f0a273 ("init.h: remove __cpuinit sections from the kernel") but we left some no-op stubs as a courtesy to unmerged code. Here we get rid of the stubs as well, since (as can be seen in these changes) they are enabling use cases to sneak back in, primarily from older BSP code that has been living out of tree for some time prior to getting mainlined. So we get rid of these "new" users 1st and then get rid of the stubs. Obviously, getting rid of the stubs can't happen until all the users are gone, so I had to keep this together as a series, even though some of these commits since got picked up into maintainers trees as well. The nature of this change is such that it should have zero impact on the generated runtime. This is one of several independent cleanup branches aimed at enabling better organization in the init.h and module.h code. They have been getting coverage in the linux-next tree for the last month, in addition to my local testing, which also covers approximately a half dozen or more architectures" * tag 'cpuinit-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: init: delete the __cpuinit related stubs kernel/cpu.c: remove new instance of __cpuinit that crept back in sched/core: remove __cpuinit section tag that crept back in. mips/mm/tlbex: remove new instance of __cpuinit that crept back in mips/c-r4k: remove legacy __cpuinit section that crept in mips/bcm77xx: remove legacy __cpuinit sections that crept in mips/ath25: remove legacy __cpuinit section that crept in arm/mach-hisi: remove legacy __CPUINIT section that crept in arm/mach-rockchip: remove legacy __cpuinit section that crept in arm/mach-mvebu: remove legacy __cpuinit sections that crept in arm/mach-keystone: remove legacy __cpuinit sections that crept in
