Amir Vadai says: ==================== cpumask,net: Affinity hint helper function This patchset will set affinity hint to influence IRQs to be allocated on the same NUMA node as the one where the card resides. As discussed in http://www.spinics.net/lists/netdev/msg271497.html If the number of IRQs allocated is greater than the number of local NUMA cores, all local cores will be used first, and the rest of the IRQs will be on a remote NUMA node. If no NUMA support - IRQ's and cores will be mapped 1:1 Since the utility function to calculate the mapping could be useful in other mq drivers in the kernel, it was added to cpumask.[ch] This patchset was tested and applied on top of net-next since the first consumer is a network device (mlx4_en). Over commit 506724c: "tg3: Override clock, link aware and link idle mode during NVRAM dump" I couldn't find a maintainer for cpumask.c, so only added the kernel mailing list Amir Changes from V5: - Moved the utility function from kernel/irq/manage.c to lib/cpumask.c, and renamed it's name accordingly to cpumask_set_cpu_local_first() - Added some comments as Thomas Gleixner suggested - Changed -EINVAL to -EAGAIN, that describes the error situtation better. Changes from V4: - Patch 1/2: irq: Utility function to get affinity_hint by policy Thank you Ben for the great review: - Moved the function it kernel/irq/manage.c since it could be useful for block mq devices - Fixed Typo's - Use cpumask_t * instead of cpumask_var_t in function header - Restructured the function to remove NULL assignment in a cpumask_var_t - Fix for offline local CPU's Changes from V3: - Patch 2/2: net/mlx4_en: Use affinity hint - somehow patch file was corrupted Changes from V2: - Patch 1/2: net: Utility function to get affinity_hint by policy - Fixed style issues Changes from V1: - Patch 1/2: net: Utility function to get affinity_hint by policy - Fixed error flow to return -EINVAL on error (thanks govind) - Patch 2/2: net/mlx4_en: Use affinity hint - Set ring->affinity_hint to NULL on error Changes from V0: - Fixed small style issues ==================== Signed-off-by: David S.

2014-06-01net/mlx4_en: Use affinity hintYuval Atias
The “affinity hint” mechanism is used by the user space daemon, irqbalancer, to indicate a preferred CPU mask for irqs. Irqbalancer can use this hint to balance the irqs between the cpus indicated by the mask. We wish the HCA to preferentially map the IRQs it uses to numa cores close to it. To accomplish this, we use cpumask_set_cpu_local_first(), that sets the affinity hint according the following policy: First it maps IRQs to “close” numa cores. If these are exhausted, the remaining IRQs are mapped to “far” numa cores. Signed-off-by: Yuval Atias <yuvala@mellanox.com> Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.

2014-06-01cpumask: Utility function to set n'th cpu - local cpu firstAmir Vadai
This function sets the n'th cpu - local cpu's first. For example: in a 16 cores server with even cpu's local, will get the following values: cpumask_set_cpu_local_first(0, numa, cpumask) => cpu 0 is set cpumask_set_cpu_local_first(1, numa, cpumask) => cpu 2 is set ... cpumask_set_cpu_local_first(7, numa, cpumask) => cpu 14 is set cpumask_set_cpu_local_first(8, numa, cpumask) => cpu 1 is set cpumask_set_cpu_local_first(9, numa, cpumask) => cpu 3 is set ... cpumask_set_cpu_local_first(15, numa, cpumask) => cpu 15 is set Curently this function will be used by multi queue networking devices to calculate the irq affinity mask, such that as many local cpu's as possible will be utilized to handle the mq device irq's.

2014-05-31Bluetooth: Fix requiring SMP MITM for outgoing connectionsJohan Hedberg
Due to recent changes to the way that the MITM requirement is set for outgoing pairing attempts we can no longer rely on the hcon->auth_type variable (which is actually good since it was formed from BR/EDR concepts that don't really exist for SMP). To match the logic that BR/EDR now uses simply rely on the local IO capability and/or needed security level to set the MITM requirement for outgoing pairing requests.

2014-05-31dcache: add missing lockdep annotationLinus Torvalds
lock_parent() very much on purpose does nested locking of dentries, and is careful to maintain the right order (lock parent first). But because it didn't annotate the nested locking order, lockdep thought it might be a deadlock on d_lock, and complained. Add the proper annotation for the inner locking of the child dentry to make lockdep happy. Introduced by commit 046b961b45f9 ("shrink_dentry_list(): take parent's ->d_lock earlier").

2014-05-30Bluetooth: 6LoWPAN: Fix MAC address universal/local bit handlingJukka Rissanen
The universal/local bit handling was incorrectly done in the code. So when setting EUI address from BD address we do this: - If BD address type is PUBLIC, then we clear the universal bit in EUI address. If the address type is RANDOM, then the universal bit is set (BT 6lowpan draft chapter 3.2.2) - After this we invert the universal/local bit according to RFC 2464 When figuring out BD address we do the reverse: - Take EUI address from stateless IPv6 address, invert the universal/local bit according to RFC 2464 - If universal bit is 1 in this modified EUI address, then address type is set to RANDOM, otherwise it is PUBLIC Note that 6lowpan_iphc.[ch] does the final toggling of U/L bit before sending or receiving the network packet.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e and i40evf. Kevin updates the i40e and i40evf driver i40e_check_asq_alive() to ensure the length register offset is non-zero which indicates that the software has initialized the admin queue. Also removes PCTYPE definitions which are now reserved. Mitch enables descriptor prefetch for rings belonging to the virtual function. Also configures the VF minimum transmit rate to 50 Mbps rather than 0 which was be interpreted as no limit at all. Mitch found in order for the VF to achieve its programmed transmit rate, we need to set the max credit value to 4. Lastly fixes a Tx hang and firmware crash that happens after setting the MTU on a VF by not using the RESETTING state during reinit, this is because the RESETTING state means that a catastrophic hardware bad thing is happening and the driver needs to tiptoe around and not use the admin queue or registers. A reinit is no big deal and we can use the admin queue (and we should) so do not set the state to RESETTING during reinit to resolve the bug. Akeem changes the declaration of the transmit and receive rings inside several loops to eliminate declaring the same ring every time for the duration of the loop and declares them just once before the loop. Also fixes the driver to clear the recovery pending bit if pf_reset fails instead of falling through the setup process. Anjali makes a change based on feedback from Ben Hutchings that cmd->data needs to be reported in ETHTOOL_GRXCLSRLCNT and use a helper function to calculate the total filter count. Jesse removes storm control since the storm control features are not apart of the hardware and were mistakenly left in the code. Greg changes tx_lpi_status and rx_lpi_status from bool to u32 to avoid sparse errors. Shannon adds the clear_pxe AdminQ API call to tell the firmware that the driver is taking over from PXE. In addition, relaxes the firmware API check to allow more flexibility in handling newer NICs and NVMs in the field. Vasu ensures that FCoE is disabled for MFP modes since it is not supported by overriding the hardware FCoE capability. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-05-30be2net: re-factor MCCQ error status handling codeKalesh AP
This patch improves MCCQ error status handling in the following ways: a) A MCC cmd completion returns a base-status and an addl-status. So far, the routine be_mcc_compl_process() returned only the "status" value. Now, embedd both statuses in the return value and let the caller routine access the value of interest using base_status() and addl_status() macros. b) Rename variables accordingly (base/addl) to avoid confusion while error checking. b) Some of the errors returned by FW are harmless and so an error msg is not logged for such errors.

Whatever it was, it can safely be removed now. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-30net: tile: Remove unnecessary memset of netdev private dataTobias Klauser
The memory for private data is allocated using kzalloc/vzalloc in alloc_netdev_mqs, thus there is no need to zero it again in the driver. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Acked-by: Chris Metcalf <cmetcalf@tilera.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-30net: tile: Use helpers from linux/etherdevice.h to check/set MACTobias Klauser
Use is_zero_ether_addr() to check for the MAC address being all zeros instead of open coding the check. Also use ether_addr_copy() instead of a manual memcpy() to set the netdev->dev_addr. Furthermore, get rid of a redundant assignment of netdev->addr_len. This is already set by ether_setup() which is called in tile_net_setup().

2014-05-30bnx2x: update MAINTAINERS for bnx2x and e-mail addressesAriel Elior
The bnx2x development team has transferred from Broadcom to Qlogic. This patch updates some obsolete email addresses to usable ones. The bnx2x files contain headers with legal information from Broadcom. Qlogic Legal depratment is taking their time coming up with their own legal info. So this patch only updates contact information. I will follow up with a patch for the headers once I have the required info. Signed-off-by: Ariel Elior <ariel.elior@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>

when system suspend, need to set pins to low power state to save IO power consumption, there are three states of pinctrl: "default", "idle" and "sleep". Currently enet supports default and sleep state. Signed-off-by: Fugang Duan <B38611@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-30net/mlx4_core: Reset RoCE VF gids when guest driver goes downJack Morgenstein
Reset the GIDs assigned to a VF in the port RoCE GID table when that guest goes down (either crashes or goes down cleanly). As part of this fix, we refactor the RoCE gid table driver copy, moving it to the mlx4_port_info structure (together with the MAC and VLAN tables). As with the MAC and VLAN tables, we now use a mutex per port for the GID table so that modifying the driver copy and modifying the firmware copy of a port GID table becomes an atomic operation (thus avoiding driver-copy/FW-copy mismatches).

2014-05-30net: filter: use block statements in tcpdump testsDaniel Borkmann
This patch converts raw opcodes for tcpdump tests into BPF_STMT()/BPF_JUMP() combinations, which brings it into conformity with the rest of the patches and it also makes life easier to grasp what's going on in these particular test cases when they ever fail. Also arrange payload from the jump+holes test in a way as we have with other packet payloads in the test suite.

2014-05-30net: filter: test fill/spill of all M[] regsDaniel Borkmann
This test for classic BPF probes stores and load combination via X on all 16 registers of the scratch memory store. It initially loads integer 100 and passes this value around to each register while incrementing it every time, thus we expect to have 116 as a result. Might be useful for JIT testing.
