Use eth_hw_addr_random() instead of calling random_ether_addr(). Here, this change is setting addr_assign_type to NET_ADDR_RANDOM. The Coccinelle semantic patch that performs this transformation is as follows: @@ identifier a,b; @@ -random_ether_addr(a->b); +eth_hw_addr_random(a); Signed-off-by:

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for your net tree. This batch mostly comes with patches to address fallout from the previous merge window cycle, they are: 1) Use entry->state.hook_list from nf_queue() instead of the global nf_hooks which is not valid when used from NFPROTO_NETDEV, this should cause no problems though since we have no userspace queueing for that family, but let's fix this now for the sake of correctness. Patch from Eric W. Biederman. 2) Fix compilation breakage in bridge netfilter if CONFIG_NF_DEFRAG_IPV4 is not set, from Bernhard Thaler. 3) Use percpu jumpstack in arptables too, now that there's a single copy of the rule blob we can't store the return address there anymore. Patch from Florian Westphal. 4) Fix a skb leak in the xmit path of bridge netfilter, problem there since 2.6.37 although it should be not possible to hit invalid traffic there, also from Florian. 5) Eric Leblond reports that when loading a large ruleset with many missing modules after a fresh boot, nf_tables can take long time commit it. Fix this by processing the full batch until the end, even on missing modules, then abort only once and restart processing. 6) Add bridge netfilter files to the MAINTAINER files. 7) Fix a net_device refcount leak in the new IPV6 bridge netfilter code, from Julien Grall. ==================== Signed-off-by: -

The limit for BQL is updated each time we call netdev_tx_completed_queue. Without this patch the BQL limit was updated for every TX event we see. The issue was that this only updated the limit to handle the data we complete in two events as the first event wouldn't show that enough traffic had been processed between them. This was OK when interrupt moderation was off but not when it was on as more data had to be completed in a single interrupt. The patch changes this so that we do report the completion to BQL only when all the TX events in the interrupt have been processed. Signed-off-by:

As its first order of business, boomerang_interrupt() checks whether the device really has any pending interrupts. If it does not, it does nothing and returns, but it still returns IRQ_HANDLED. This is wrong: interrupt was not handled, IRQ handlers of other devices sharing this IRQ line need to be called. vortex_interrupt() has it right: it returns IRQ_NONE in this case via IRQ_RETVAL(0). Do the same in boomerang_interrupt(). Signed-off-by:

vmxnet3's current napi path is built to count every rx descriptor we recieve, and use that as a count of the napi budget. That means its possible to return from a napi poll halfway through recieving a fragmented packet accross multiple dma descriptors. If that happens, the next napi poll will start with the descriptor ring in an improper state (e.g. the first descriptor we look at may have the end-of-packet bit set), which will cause a BUG halt in the driver. Fix the issue by only counting whole received packets in the napi poll and returning that value, rather than the descriptor count. Tested by the reporter and myself, successfully Signed-off-by:

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.

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.

The commit efb6de9b "netfilter: bridge: forward IPv6 fragmented packets" introduced a new function br_validate_ipv6 which take a reference on the inet6 device. Although, the reference is not released at the end. This will result to the impossibility to destroy any netdevice using ipv6 and bridge. It's possible to directly retrieve the inet6 device without taking a reference as all netfilter hooks are protected by rcu_read_lock via nf_hook_slow.

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.

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.

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
