set_filter_wr is requesting __GFP_NOFAIL allocation although it can return ENOMEM without any problems obviously (t4_l2t_set_switching does that already). So the non-failing requirement is too strong without any obvious reason. Drop __GFP_NOFAIL and reorganize the code to have the failure paths easier. The same applies to _c4iw_write_mem_dma_aligned which uses __GFP_NOFAIL and then checks the return value and returns -ENOMEM on failure. This doesn't make any sense what so ever. Either the allocation cannot fail or it can. del_filter_wr seems to be safe as well because the filter entry is not marked as pending and the return value is propagated up the stack up to c4iw_destroy_listen.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-04-14 This series contains updates to i40e and i40evf. Mitch provides a fix for i40e, where VFs were gone and the associated VSI's had been removed and the rings were not stopped, which in some circumstances cased memory corruption or DMAR errors. So stop all the rings associated with each VF before releasing its resources. Also cleaned up a poorly indented piece of code. Fixes VF link state, where VF devices were assuming link is up unless told otherwise, which means that VFs instantiated on a PF with no link, would report the wrong state. Anjali adds support to add Flow director Sideband rules for a VF from it's PF. Fixes a recently discovered hardware issue, where after a VFLR hardware might be indicating to us a reset completion little too early, so wait another 10 msec for cache to be cleaned up. Jesse enables the user to dump the internal hardware state for better debugging by allowing a bash script to acquire information about the internal hardware state. The data output to the kernel log is collected by the script and can then be sent to Intel. Also fixed a possible failure path to allocate memory that was found by smatch. Cleaned up unused local variables. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Commit 9a2620c8 ("bnx2x: prevent WARN during driver unload") switched the napi/busy_lock locking mechanism from spin_lock() into spin_lock_bh(), breaking inter-operability with netconsole, as netpoll disables interrupts prior to calling our napi mechanism. This switches the driver into using atomic assignments instead of the spinlock mechanisms previously employed. Based on initial patch from Yuval Mintz & Ariel Elior I basically added softirq starvation avoidance, and mixture of atomic operations, plain writes and barriers. Note this slightly reduces the overhead for this driver when no busy_poll sockets are in use.

The code sets the expiry value of the timer to a relative value and starts it with hrtimer_start_expires. That's fine, but that only works once. The timer is started in relative mode, so the expiry value gets overwritten with the absolut expiry time (now + expiry). So once the timer expired, a new call to hrtimer_start_expires results in an immidiately expired timer, because the expiry value is already in the past. Use the proper mechanisms to (re)start the timer in the intended way. Signed-off-by: NThomas Gleixner <tglx@linutronix.de> Cc: "David S.

All from Eric Biederman. 7) Support L3 forwarding offloading in switches, from Scott Feldman. 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed up route lookups even further. From Alexander Duyck. 9) Many improvements and bug fixes to the rhashtable implementation, from Herbert Xu and Thomas Graf.

Pull ARM updates from Russell King: "Included in this update are both some long term fixes and some new features. Fixes: - An integer overflow in the calculation of ELF_ET_DYN_BASE. - Avoiding OOMs for high-order IOMMU allocations - SMP requires the data cache to be enabled for synchronisation primitives to work, so prevent the CPU_DCACHE_DISABLE option being visible on SMP builds. - A bug going back 10+ years in the noMMU ARM94* CPU support code, where it corrupts registers. Found by folk getting Linux running on their cameras. - Versatile Express needs an errata workaround enabled for CPU hot-unplug to work. Features: - Clean up module linker by handling out of range relocations separately from relocation cases we don't handle. - Fix a long term bug in the pci_mmap_page_range() code, which we hope won't impact userspace (we hope there's no users of the existing broken interface.) - Don't map DMA coherent allocations when we don't have a MMU. - Drop experimental status for SMP_ON_UP. - Warn when DT doesn't specify ePAPR mandatory cache properties. - Add documentation concerning how we find the start of physical memory for AUTO_ZRELADDR kernels, detailing why we have chosen the mask and the implications of changing it. - Updates from Ard Biesheuvel to address some issues with large kernels (such as allyesconfig) failing to link. - Allow hibernation to work on modern (ARMv7) CPUs - this appears to have never worked in the past on these CPUs. - Enable IRQ_SHOW_LEVEL, which changes the /proc/interrupts output format (hopefully without userspace breaking... let's hope that if it causes someone a problem, they tell us.) - Fix tegra-ahb DT offsets. - Rework ARM errata 643719 code (and ARMv7 flush_cache_louis()/ flush_dcache_all()) code to be more efficient, and enable this errata workaround by default for ARMv7+SMP CPUs. This complements the Versatile Express fix above. - Rework ARMv7 context code for errata 430973, so that only Cortex A8 CPUs are impacted by the branch target buffer flush when this errata is enabled. Also update the help text to indicate that all r1p* A8 CPUs are impacted. - Switch ARM to the generic show_mem() implementation, it conveys all the information which we were already reporting. - Prevent slow timer sources being used for udelay() - timers running at less than 1MHz are not useful for this, and can cause udelay() to return immediately, without any wait. Using such a slow timer is silly. - VDSO support for 32-bit ARM, mainly for gettimeofday() using the ARM architected timer. - Perf support for Scorpion performance monitoring units" vdso semantic conflict fixed up as per linux-next. * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (52 commits) ARM: update errata 430973 documentation to cover Cortex A8 r1p* ARM: ensure delay timer has sufficient accuracy for delays ARM: switch to use the generic show_mem() implementation ARM: proc-v7: avoid errata 430973 workaround for non-Cortex A8 CPUs ARM: enable ARM errata 643719 workaround by default ARM: cache-v7: optimise test for Cortex A9 r0pX devices ARM: cache-v7: optimise branches in v7_flush_cache_louis ARM: cache-v7: consolidate initialisation of cache level index ARM: cache-v7: shift CLIDR to extract appropriate field before masking ARM: cache-v7: use movw/movt instructions ARM: allow 16-bit instructions in ALT_UP() ARM: proc-arm94*.S: fix setup function ARM: vexpress: fix CPU hotplug with CT9x4 tile.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-04-14 This series contains updates to fm10k only. Fixed transmit statistics which was actually using values from the receive ring, instead of the transmit ring. Fixed up spelling mistakes in code comments and resolved unused argument warnings. Added support for netconsole. Fixed up statistic reporting so that we are only reporting from actual queues as well as display PF only stats for just the PF and not the VF. Also fixed an issue that when returning virtualization queues from the VF back to the PF, we were retaining the VF rate limiter. Fixed up the driver to use a separate workqueue, which helps reduce and stabilize latency between scheduling the work in our interrupt and actually performing the work. Fixed a bug where the VF tried to set a multicast address before requesting the required xcast mode. Fix VF multicast update since VFs were being improperly added to the switch's mutlicast group. The error stems from the fact that incorrect arguments were passed to the update_mc_addr(). Thanks to Alex Duyck for the extensive review. ==================== Signed-off-by: NDavid S.

Gratuitously notify VFs of link state when they activate their queues. In general, this is the last thing that a VF driver will do as it opens its interface, so this is a good time to notify the VF. Currently, VF devices assume link is up unless told otherwise, which means that VFs instantiated on a PF with no link will report the wrong state. This change corrects that issue.

The aq_pending field in the adapter structure is actually redundant with the current_op field. Remove the aq_pending field and expunge all traces of it from the official record.

When task->comm is passed directly to audit_log_untrustedstring() without getting a copy or using the task_lock, there is a race that could happen that would output a NULL (\0) in the middle of the output string that would effectively truncate the rest of the report text after the comm= field in the audit log message, losing fields. Using get_task_comm() to get a copy while acquiring the task_lock to prevent this and to prevent the result from being a mixture of old and new values of comm would incur potentially unacceptable overhead, considering that the value can be influenced by userspace and therefore untrusted anyways. Copy the value before passing it to audit_log_untrustedstring() ensures that a local copy is used to calculate the length *and* subsequently printed. Even if this value contains a mix of old and new values, it will only calculate and copy up to the first NULL, preventing the rest of the audit log message being truncated. Use a second local copy of comm to avoid a race between the first and second calls to audit_log_untrustedstring() with comm.

Explicitly stop the rings belonging to each VF when disabling SR-IOV. Even though the VFs were gone, and the associated VSIs were removed, the rings were not stopped, and in some circumstances the hardware would continue to access the memory formerly used by the rings, causing memory corruption or DMAR errors, both of which would lead to general malaise of the kernel. To relieve this condition, explicitly stop all the rings associated with each VF before releasing its resources.
