git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the big driver core update for 4.13-rc1. The large majority of this is a lot of cleanup of old fields in the driver core structures and their remaining usages in random drivers. All of those fixes have been reviewed by the various subsystem maintainers. There's also some small firmware updates in here, a new kobject uevent api interface that makes userspace interaction easier, and a few other minor things.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler updates from Ingo Molnar: "The main changes in this cycle were: - Add the SYSTEM_SCHEDULING bootup state to move various scheduler debug checks earlier into the bootup. This turns silent and sporadically deadly bugs into nice, deterministic splats. Fix some of the splats that triggered. (Thomas Gleixner) - A round of restructuring and refactoring of the load-balancing and topology code (Peter Zijlstra) - Another round of consolidating ~20 of incremental scheduler code history: this time in terms of wait-queue nomenclature. (I didn't get much feedback on these renaming patches, and we can still easily change any names I might have misplaced, so if anyone hates a new name, please holler and I'll fix it.) (Ingo Molnar) - sched/numa improvements, fixes and updates (Rik van Riel) - Another round of x86/tsc scheduler clock code improvements, in hope of making it more robust (Peter Zijlstra) - Improve NOHZ behavior (Frederic Weisbecker) - Deadline scheduler improvements and fixes (Luca Abeni, Daniel Bristot de Oliveira) - Simplify and optimize the topology setup code (Lauro Ramos Venancio) - Debloat and decouple scheduler code some more (Nicolas Pitre) - Simplify code by making better use of llist primitives (Byungchul Park) - ... plus other fixes and improvements" * 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (103 commits) sched/cputime: Refactor the cputime_adjust() code sched/debug: Expose the number of RT/DL tasks that can migrate sched/numa: Hide numa_wake_affine() from UP build sched/fair: Remove effective_load() sched/numa: Implement NUMA node level wake_affine() sched/fair: Simplify wake_affine() for the single socket case sched/numa: Override part of migrate_degrades_locality() when idle balancing sched/rt: Move RT related code from sched/core.c to sched/rt.c sched/deadline: Move DL related code from sched/core.c to sched/deadline.c sched/cpuset: Only offer CONFIG_CPUSETS if SMP is enabled sched/fair: Spare idle load balancing on nohz_full CPUs nohz: Move idle balancer registration to the idle path sched/loadavg: Generalize "_idle" naming to "_nohz" sched/core: Drop the unused try_get_task_struct() helper function sched/fair: WARN() and refuse to set buddy when !se->on_rq sched/debug: Fix SCHED_WARN_ON() to return a value on !CONFIG_SCHED_DEBUG as well sched/wait: Disambiguate wq_entry->task_list and wq_head->task_list naming sched/wait: Move bit_wait_table[] and related functionality from sched/core.c to sched/wait_bit.c sched/wait: Split out the wait_bit*() APIs from <linux/wait.h> into <linux/wait_bit.h> sched/wait: Re-adjust macro line continuation backslashes in <linux/wait.h> ...

2017-06-29sfc: fix attempt to translate invalid filter IDEdward Cree
When filter insertion fails with no rollback, we were trying to convert EFX_EF10_FILTER_ID_INVALID to an id to store in 'ids' (which is either vlan->uc or vlan->mc). This would WARN_ON_ONCE and then record a bogus filter ID of 0x1fff, neither of which is a good thing.

2017-06-29mlxsw: spectrum_router: Fix NULL pointer dereferenceIdo Schimmel
In case a VLAN device is enslaved to a bridge we shouldn't create a router interface (RIF) for it when it's configured with an IP address. This is already handled by the driver for other types of netdevs, such as physical ports and LAG devices. If this IP address is then removed and the interface is subsequently unlinked from the bridge, a NULL pointer dereference can happen, as the original 802.1d FID was replaced with an rFID which was then deleted. To reproduce: $ ip link set dev enp3s0np9 up $ ip link add name enp3s0np9.111 link enp3s0np9 type vlan id 111 $ ip link set dev enp3s0np9.111 up $ ip link add name br0 type bridge $ ip link set dev br0 up $ ip link set enp3s0np9.111 master br0 $ ip address add dev enp3s0np9.111 192.168.0.1/24 $ ip address del dev enp3s0np9.111 192.168.0.1/24 $ ip link set dev enp3s0np9.111 nomaster Fixes: 99724c18fc66 ("mlxsw: spectrum: Introduce support for router interfaces") Signed-off-by: Ido Schimmel <idosch@mellanox.com> Reported-by: Petr Machata <petrm@mellanox.com> Tested-by: Petr Machata <petrm@mellanox.com> Reviewed-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S.

2017-06-23bnxt_en: Fix netpoll handling.Michael Chan
To handle netpoll properly, the driver must only handle TX packets during NAPI. Handling RX events cause warnings and errors in netpoll mode. The ndo_poll_controller() method should call napi_schedule() directly so that a NAPI weight of zero will be used during netpoll mode. The bnxt_en driver supports 2 ring modes: combined, and separate rx/tx. In separate rx/tx mode, the ndo_poll_controller() method will only process the tx rings. In combined mode, the rx and tx completion entries are mixed in the completion ring and we need to drop the rx entries and recycle the rx buffers. Add a function bnxt_force_rx_discard() to handle this in netpoll mode when we see rx entries in combined ring mode.

2017-06-22macvlan: Let passthru macvlan correctly restore lower mac addressVlad Yasevich
Passthru macvlans directly change the mac address of the lower level device. That's OK, but after the macvlan is deleted, the lower device is left with changed address and one needs to reboot to bring back the origina HW addresses. This scenario is actually quite common with passthru macvtap devices. This patch attempts to solve this, by storing the mac address of the lower device in macvlan_port structure and keeping track of it through the changes. After this patch, any changes to the lower device mac address done trough the macvlan device, will be reverted back. Any changs done directly to the lower device mac address will be kept.

2017-06-22macvlan: Fix passthru macvlan mac address inheritanceVlad Yasevich
When a lower device of the passthru macvlan changes it's address, passthru macvlan is supposed to change it's own address as well. However, that doesn't happen correctly because the check in macvlan_addr_busy() will catch the fact that the lower level (port) mac address is the same as the address we are trying to assign to the macvlan, and return an error. As a reasult, the address of the passthru macvlan device is never changed. The same thing happens when the user attempts to change the mac address of the passthru macvlan. The simple solution appers to be to not check against the lower device in case of passthru macvlan device, since the 2 addresses are _supposed_ to be the same.

First it is not feasible to configure both network devices with same MAC address since this makes communication in such configuration problematic. This case can be reproduced with following sequence: # ip link add address 02:11:22:33:44:55 type veth # ip li sh ... 26: veth0@veth1: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc \ noop state DOWN mode DEFAULT qlen 1000 link/ether 00:11:22:33:44:55 brd ff:ff:ff:ff:ff:ff 27: veth1@veth0: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc \ noop state DOWN mode DEFAULT qlen 1000 link/ether 00:11:22:33:44:55 brd ff:ff:ff:ff:ff:ff Second it is not possible to register both main and peer network devices with same name, that happens when name for main interface is given with IFLA_IFNAME and same attribute reused for peer. This case can be reproduced with following sequence: # ip link add dev veth1a type veth RTNETLINK answers: File exists To fix both of the cases check if corresponding netlink attributes are taken from peer_tb when valid or name based on rtnl ops kind and random address is used.

Rename: wait_queue_t => wait_queue_entry_t 'wait_queue_t' was always a slight misnomer: its name implies that it's a "queue", but in reality it's a queue *entry*. The 'real' queue is the wait queue head, which had to carry the name. Start sorting this out by renaming it to 'wait_queue_entry_t'. This also allows the real structure name 'struct __wait_queue' to lose its double underscore and become 'struct wait_queue_entry', which is the more canonical nomenclature for such data types.

2017-06-19cxgb4: notify uP to route ctrlq compl to rdma rspqRaju Rangoju
During the module initialisation there is a possible race (basically race between uld and lld) where neither the uld nor lld notifies the uP about where to route the ctrl queue completions. LLD skips notifying uP as the rdma queues were not created by then (will leave it to ULD to notify the uP). As the ULD comes up, it also skips notifying the uP as the flag FULL_INIT_DONE is not set yet (ULD assumes that the interface is not up yet). Consequently, this race between uld and lld leaves uP unnotified about where to send the ctrl queue completions to, leading to iwarp RI_RES WR failure. Here is the race: CPU 0 CPU1 - allocates nic rx queus - t4_sge_alloc_ctrl_txq() (if rdma rsp queues exists, tell uP to route ctrl queue compl to rdma rspq) - acquires the mutex_lock - allocates rdma response queues - if FULL_INIT_DONE set, tell uP to route ctrl queue compl to rdma rspq - relinquishes mutex_lock - acquires the mutex_lock - enable_rx() - set FULL_INIT_DONE - relinquishes mutex_lock This patch fixes the above issue.

2017-06-15brcmfmac: unbind all devices upon failure in firmware callbackArend Van Spriel
When request firmware fails, brcmf_ops_sdio_remove is being called and brcmf_bus freed. In such circumstancies if you do a suspend/resume cycle the kernel hangs on resume due a NULL pointer dereference in resume function. So in brcmf_sdio_firmware_callback() we need to unbind the driver from both sdio_func devices when firmware load failure is indicated.

2017-06-15brcmfmac: use firmware callback upon failure to loadArend Van Spriel
When firmware loading failed the code used to unbind the device provided by the calling code. However, for the sdio driver two devices are bound and both need to be released upon failure. The callback has been extended with parameter to pass error code so add that in this commit upon firmware loading failure.

2017-06-15brcmfmac: add parameter to pass error code in firmware callbackArend Van Spriel
Extend the parameters in the firmware callback so it can be called upon success and failure. This allows the caller to properly clear all resources in the failure path. Right now the error code is always zero, ie. success.
