The be_cmd_rx_filter() routine sends a non-embedded cmd to the FW and used a pre-allocated dma memory to hold the cmd payload. This worked fine when this cmd was synchronous. This cmd was changed to asynchronous mode by the commit 8af65c2f("make the RX_FILTER command asynchronous"). So now when there are two quick invocations of this cmd, the 2nd request may end up overwriting the first request, causing FW cmd corruption. This patch reverts the offending commit and hence fixes the regression. Fixes: 8af65c2f("be2net: make the RX_FILTER command asynchronous") Signed-off-by:

Conflicts: include/net/netfilter/nf_conntrack.h The conflict was an overlap between changing the type of the zone argument to nf_ct_tmpl_alloc() whilst exporting nf_ct_tmpl_free. Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for net, they are: 1) Oneliner to restore maps in nf_tables since we support addressing registers at 32 bits level. 2) Restore previous default behaviour in bridge netfilter when CONFIG_IPV6=n, oneliner from Bernhard Thaler. 3) Out of bound access in ipset hash:net* set types, reported by Dave Jones' KASan utility, patch from Jozsef Kadlecsik. 4) Fix ipset compilation with gcc 4.4.7 related to C99 initialization of unnamed unions, patch from Elad Raz. 5) Add a workaround to address inconsistent endianess in the res_id field of nfnetlink batch messages, reported by Florian Westphal. 6) Fix error paths of CT/synproxy since the conntrack template was moved to use kmalloc, patch from Daniel Borkmann. All of them look good to me to reach 4.2, I can route this to -stable myself too, just let me know what you prefer. ==================== Signed-off-by:

In the IPv6 multicast routing code the mrt_lock was not being released correctly in the MFC iterator, as a result adding or deleting a MIF would cause a hang because the mrt_lock could not be acquired. This fix is a copy of the code for the IPv4 case and ensures that the lock is released correctly. Signed-off-by:

Marcelo Ricardo Leitner says: ==================== couple of sctp fixes for 0ca50d12 These are two fixes for sctp after my patch on 0ca50d12 ("sctp: fix src address selection if using secondary addresses") The first, fix a dst leak on those it decided to skip. The second, adds the fallback on src selection that Vlad had asked about. Unfortunatelly a lot of ipvs setups relies on the old behavior and I don't see a better fix for it. Please consider both to -stable tree. ==================== Acked-by:

Commit 0ca50d12 added a restriction that the address must belong to the output interface, so that sctp will use the right interface even when using secondary addresses. But it breaks IPVS setups, on which people is used to attach VIP addresses to loopback interface on real servers. It's preferred to attach to the interface actually in use, but it's a very common setup and that used to work. This patch then saves the first routing good result, even if it would be going out through an interface that doesn't have that address. If no better hit found, it's then used. This effectively restores the original behavior if no better interface could be found. Fixes: 0ca50d12 ("sctp: fix src address selection if using secondary addresses") Signed-off-by:

Therefore, split the more generic parts into a common header under include/linux/netfilter/ and move nf_ct_zone_dflt into the built-in section that already holds parts related to CONFIG_NF_CONNTRACK in the netfilter core. This fixes the issue on my side. Fixes: 308ac914 ("netfilter: nf_conntrack: push zone object into functions") Reported-by:

The patch just to re-submit the patch "db3421c1" because the patch "4d494cdc" remove the change. Clear any pending receive interrupt before we process a pending packet. This helps to avoid any spurious interrupts being raised after we have fully cleaned the receive ring, while still allowing an interrupt to be raised if we receive another packet. The position of this is critical: we must do this prior to reading the next packet status to avoid potentially dropping an interrupt when a packet is still pending. Acked-by:

Pull core block updates from Jens Axboe: "This first core part of the block IO changes contains: - Cleanup of the bio IO error signaling from Christoph. We used to rely on the uptodate bit and passing around of an error, now we store the error in the bio itself. - Improvement of the above from myself, by shrinking the bio size down again to fit in two cachelines on x86-64. - Revert of the max_hw_sectors cap removal from a revision again, from Jeff Moyer. This caused performance regressions in various tests. Reinstate the limit, bump it to a more reasonable size instead. - Make /sys/block/<dev>/queue/discard_max_bytes writeable, by me.

From Ming Lei. - Also from Ming Lei, a basic fixup for overflow of the sysfs pending file in blk-mq, as well as a fix for a blk-mq timeout race condition. - Ming Lin has been carrying Kents above mentioned patches forward for a while, and testing them.

Xen's PV network protocol includes messages to add/remove ethernet multicast addresses to/from a filter list in the backend. This allows the frontend to request the backend only forward multicast packets which are of interest thus preventing unnecessary noise on the shared ring. The canonical netif header in git://xenbits.xen.org/xen.git specifies the message format (two more XEN_NETIF_EXTRA_TYPEs) so the minimal necessary changes have been pulled into include/xen/interface/io/netif.h. To prevent the frontend from extending the multicast filter list arbitrarily a limit (XEN_NETBK_MCAST_MAX) has been set to 64 entries. This limit is not specified by the protocol and so may change in future. If the limit is reached then the next XEN_NETIF_EXTRA_TYPE_MCAST_ADD sent by the frontend will be failed with NETIF_RSP_ERROR.

diag socket's sock_diag_put_filterinfo() dumps classic BPF programs upon request to user space (ss -0 -b). However, native eBPF programs attached to sockets (SO_ATTACH_BPF) cannot be dumped with this method: Their orig_prog is always NULL. However, sock_diag_put_filterinfo() unconditionally tries to access its filter length resp. wants to copy the filter insns from there. Internal cBPF to eBPF transformations attached to sockets don't have this issue, as orig_prog state is kept. It's currently only used by packet sockets. If we would want to add native eBPF support in the future, this needs to be done through a different attribute than PACKET_DIAG_FILTER to not confuse possible user space disassemblers that work on diag data.

There is no such ordering enforced in C, so this incorrect. This patch fixes that by splitting out the arguments. This bug was found via a compiler warning that keys may be uninitialized.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-09-01 This series contains updates to i40e, ixgbe and ixgbevf. Anjali fixes a bug in i40e where the port is not receiving multicast or VLAN tagged packets in promiscuous mode. Which can occur when a software bridge is created on top of the device. Don adds support in ixgbe that indicates the presence of management firmware. Added support for entering low power link up state on devices that support it when the device is closing or suspending. Updated the driver to report unknown bus speed and width since IOSF does not report a PCIe bus speed or width for X550 devices. Also added the new bus type for integrated I/O interface (IOSF). Cleaned up of redundant code in ixgbe. Mark adds support for UDP-encapsulation transmit checksum and for VXLAN receive offloads. Introduces a helper function to do the register access and processing to avoid needless PHY access on copper PHYs. Added support for reporting 2.5G link speed. Fixed warnings resulting from redundant initializations of the get_bus_info field. Maninder Singh updates the ixgbe driver to use kzalloc instead of kcalloc for allocation of one thing. Tom Barbette adds support for ethtool to change the rxfh indirection table and/or key using ethtool interface. Emil resolves an issue where users were not able to dynamically set number of queues for 82598 via ethtool -L. Alex Williamson removes bimodal SR-IOV disabling behavior since it is confusing to users and results in a state where the PF is broken for other uses unless the user sets sriov_numvfs to zero prior to unbinding the device. ==================== Signed-off-by:

Pull power management and ACPI updates from Rafael Wysocki: "From the number of commits perspective, the biggest items are ACPICA and cpufreq changes with the latter taking the lead (over 50 commits). On the cpufreq front, there are many cleanups and minor fixes in the core and governors, driver updates etc. We also have a new cpufreq driver for Mediatek MT8173 chips. ACPICA mostly updates its debug infrastructure and adds a number of fixes and cleanups for a good measure. The Operating Performance Points (OPP) framework is updated with new DT bindings and support for them among other things. We have a few updates of the generic power domains framework and a reorganization of the ACPI device enumeration code and bus type operations. And a lot of fixes and cleanups all over. Included is one branch from the MFD tree as it contains some PM-related driver core and ACPI PM changes a few other commits are based on. Specifics: - ACPICA update to upstream revision 20150818 including method tracing extensions to allow more in-depth AML debugging in the kernel and a number of assorted fixes and cleanups (Bob Moore, Lv Zheng, Markus Elfring). - ACPI sysfs code updates and a documentation update related to AML method tracing (Lv Zheng). - ACPI EC driver fix related to serialized evaluations of _Qxx methods and ACPI tools updates allowing the EC userspace tool to be built from the kernel source (Lv Zheng). - ACPI processor driver updates preparing it for future introduction of CPPC support and ACPI PCC mailbox driver updates (Ashwin Chaugule). - ACPI interrupts enumeration fix for a regression related to the handling of IRQ attribute conflicts between MADT and the ACPI namespace (Jiang Liu). - Fixes related to ACPI device PM (Mika Westerberg, Srinidhi Kasagar). - ACPI device registration code reorganization to separate the sysfs-related code and bus type operations from the rest (Rafael J Wysocki). - Assorted cleanups in the ACPI core (Jarkko Nikula, Mathias Krause, Andy Shevchenko, Rafael J Wysocki, Nicolas Iooss). - ACPI cpufreq driver and ia64 cpufreq driver fixes and cleanups (Pan Xinhui, Rafael J Wysocki). - cpufreq core cleanups on top of the previous changes allowing it to preseve its sysfs directories over system suspend/resume (Viresh Kumar, Rafael J Wysocki, Sebastian Andrzej Siewior). - cpufreq fixes and cleanups related to governors (Viresh Kumar). - cpufreq updates (core and the cpufreq-dt driver) related to the turbo/boost mode support (Viresh Kumar, Bartlomiej Zolnierkiewicz). - New DT bindings for Operating Performance Points (OPP), support for them in the OPP framework and in the cpufreq-dt driver plus related OPP framework fixes and cleanups (Viresh Kumar). - cpufreq powernv driver updates (Shilpasri G Bhat). - New cpufreq driver for Mediatek MT8173 (Pi-Cheng Chen). - Assorted cpufreq driver (speedstep-lib, sfi, integrator) cleanups and fixes (Abhilash Jindal, Andrzej Hajda, Cristian Ardelean). - intel_pstate driver updates including Skylake-S support, support for enabling HW P-states per CPU and an additional vendor bypass list entry (Kristen Carlson Accardi, Chen Yu, Ethan Zhao). - cpuidle core fixes related to the handling of coupled idle states (Xunlei Pang). - intel_idle driver updates including Skylake Client support and support for freeze-mode-specific idle states (Len Brown). - Driver core updates related to power management (Andy Shevchenko, Rafael J Wysocki). - Generic power domains framework fixes and cleanups (Jon Hunter, Geert Uytterhoeven, Rajendra Nayak, Ulf Hansson). - Device PM QoS framework update to allow the latency tolerance setting to be exposed to user space via sysfs (Mika Westerberg). - devfreq support for PPMUv2 in Exynos5433 and a fix for an incorrect exynos-ppmu DT binding (Chanwoo Choi, Javier Martinez Canillas). - System sleep support updates (Alan Stern, Len Brown, SungEun Kim). - rockchip-io AVS support updates (Heiko Stuebner). - PM core clocks support fixup (Colin Ian King). - Power capping RAPL driver update including support for Skylake H/S and Broadwell-H (Radivoje Jovanovic, Seiichi Ikarashi). - Generic device properties framework fixes related to the handling of static (driver-provided) property sets (Andy Shevchenko). - turbostat and cpupower updates (Len Brown, Shilpasri G Bhat, Shreyas B Prabhu)" * tag 'pm+acpi-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (180 commits) cpufreq: speedstep-lib: Use monotonic clock cpufreq: powernv: Increase the verbosity of OCC console messages cpufreq: sfi: use kmemdup rather than duplicating its implementation cpufreq: drop !cpufreq_driver check from cpufreq_parse_governor() cpufreq: rename cpufreq_real_policy as cpufreq_user_policy cpufreq: remove redundant 'policy' field from user_policy cpufreq: remove redundant 'governor' field from user_policy cpufreq: update user_policy.* on success cpufreq: use memcpy() to copy policy cpufreq: remove redundant CPUFREQ_INCOMPATIBLE notifier event cpufreq: mediatek: Add MT8173 cpufreq driver dt-bindings: mediatek: Add MT8173 CPU DVFS clock bindings PM / Domains: Fix typo in description of genpd_dev_pm_detach() PM / Domains: Remove unusable governor dummies PM / Domains: Make pm_genpd_init() available to modules PM / domains: Align column headers and data in pm_genpd_summary output powercap / RAPL: disable the 2nd power limit properly tools: cpupower: Fix error when running cpupower monitor PM / OPP: Drop unlikely before IS_ERR(_OR_NULL) PM / OPP: Fix static checker warning (broken 64bit big endian systems) ...

When unbinding an SR-IOV device with VFs configured from ixgbe, the driver behaves in one of two ways. If max_vfs was specified, the SR-IOV state is disabled, removing the VFs. The occurs regardless of whether the VF count was later modified through sysfs. If however max_vfs is zero, such as by not specifying the module parameter, the VFs persist after the PF is unbound from ixgbe. If the PF is then bound to vfio-pci to be assigned to a VM, the PF is non-functional. >From the comment, commit da36b647 ("ixgbe: Implement PCI SR-IOV sysfs callback operation") clearly intended this alternate behavior, but probably didn't realize the PF doesn't work in this mode. This bimodal behavior is confusing to users and results in a state where the PF is broken for other uses unless the user sets sriov_numvfs to zero prior to unbinding the device. Remove this behavior so that VFs are removed and the PF is functional for other uses after unbind, regardless of the way VFs are enabled. Signed-off-by:
