2015-06-21MIPS: mipsregs.h: Add EntryLo bit definitionsJames Hogan
Add definitions for EntryLo register bits in mipsregs.h. The R4000 compatible ones are prefixed MIPS_ENTRYLO_ and the R3000 compatible ones are prefixed R3K_ENTRYLO_. These will be used in later patches. Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: linux-mips@linux-mips.org Cc: Maciej W.

2015-06-21MIPS: hazards: Add hazard macros for tlb readJames Hogan
Add hazard macros to <asm/hazards.h> for the following hazards around tlbr (TLB read) instructions, which are used in TLB dumping code and some KVM TLB management code: - mtc0_tlbr_hazard Between mtc0 (Index) and tlbr. This is copied from mtc0_tlbw_hazard in all cases on the assumption that tlbr always has similar data user timings to tlbw. - tlb_read_hazard Between tlbr and mfc0 (various TLB registers). This is copied from tlbw_use_hazard in all cases on the assumption that tlbr has similar data writer characteristics to tlbw, and mfc0 has similar data user characteristics to loads and stores.

2015-06-21i2c: designware: Make sure the device is suspended before disabling runtime PMMika Westerberg
The driver calls pm_runtime_put() right before pm_runtime_disable() in its ->remove() hook to make sure clock is gated etc. However, it turns out that pm_runtime_put() only calls ->idle() hook without actually suspending anything. The following pm_runtime_disable() will prevent the driver from suspending thus leaving it "active". It is better to suspend the device synchronously to make sure it is actually suspended before disabling runtime PM from it. While there, undo call to pm_runtime_use_autosuspend().

2015-06-21netlink: add API to retrieve all group membershipsDavid Herrmann
This patch adds getsockopt(SOL_NETLINK, NETLINK_LIST_MEMBERSHIPS) to retrieve all groups a socket is a member of. Currently, we have to use getsockname() and look at the nl.nl_groups bitmask. However, this mask is limited to 32 groups. Hence, similar to NETLINK_ADD_MEMBERSHIP and NETLINK_DROP_MEMBERSHIP, this adds a separate sockopt to manager higher groups IDs than 32. This new NETLINK_LIST_MEMBERSHIPS option takes a pointer to __u32 and the size of the array. The array is filled with the full membership-set of the socket, and the required array size is returned in optlen. Hence, user-space can retry with a properly sized array in case it was too small.

2015-06-21mac80211: fix locking in update_vlan_tailroom_need_count()Johannes Berg
Unfortunately, Michal's change to fix AP_VLAN crypto tailroom caused a locking issue that was reported by lockdep, but only in a few cases - the issue was a classic ABBA deadlock caused by taking the mtx after the key_mtx, where normally they're taken the other way around. As the key mutex protects the field in question (I'm adding a few annotations to make that clear) only the iteration needs to be protected, but we can also iterate the interface list with just RCU protection while holding the key mutex.

2015-06-21can: fix loss of CAN frames in raw_rcvOliver Hartkopp
As reported by Manfred Schlaegl here http://marc.info/?l=linux-netdev&m=143482089824232&w=2 commit 514ac99c64b "can: fix multiple delivery of a single CAN frame for overlapping CAN filters" requires the skb->tstamp to be set to check for identical CAN skbs. As net timestamping is influenced by several players (netstamp_needed and netdev_tstamp_prequeue) Manfred missed a proper timestamp which leads to CAN frame loss. As skb timestamping became now mandatory for CAN related skbs this patch makes sure that received CAN skbs always have a proper timestamp set. Maybe there's a better solution in the future but this patch fixes the CAN frame loss so far.

2015-06-21neigh: do not modify unlinked entriesJulian Anastasov
The lockless lookups can return entry that is unlinked. Sometimes they get reference before last neigh_cleanup_and_release, sometimes they do not need reference. Later, any modification attempts may result in the following problems: 1. entry is not destroyed immediately because neigh_update can start the timer for dead entry, eg. on change to NUD_REACHABLE state. As result, entry lives for some time but is invisible and out of control. 2. __neigh_event_send can run in parallel with neigh_destroy while refcnt=0 but if timer is started and expired refcnt can reach 0 for second time leading to second neigh_destroy and possible crash.

hpet_assign_irq() is called with hpet_device->num as "hardware interrupt number", but hpet_device->num is initialized after the interrupt has been assigned, so it's always 0.

The nx driver reads two crucial paramters from the firmware for each crypto algorithm, the maximum SG list length and byte limit. Unfortunately those two parameters may be bogus, or worse they may be absent altogether. When this happens the algorithms will still register successfully but will fail when used or tested. This patch adds checks to report any firmware entries which are found to be bogus, and avoid registering algorithms which have bogus parameters. A warning is also printed when an algorithm is not registered because of this as there may have been no firmware entries for it at all.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains a final Netfilter pull request for net-next 4.2. This mostly addresses some fallout from the previous pull request, small netns updates and a couple of new features for nfnetlink_log and the socket match that didn't get in time for the previous pull request. More specifically they are: 1) Add security context information to nfnetlink_queue, from Roman Kubiak. 2) Add support to restore the sk_mark into skb->mark through xt_socket, from Harout Hedeshian. 3) Force alignment of 16 bytes of per cpu xt_counters, from Eric Dumazet. 4) Rename br_netfilter.c to br_netfilter_hooks.c to prepare split of IPv6 code into a separated file. 5) Move the IPv6 code in br_netfilter into a separated file. 6) Remove unused RCV_SKB_FAIL() in nfnetlink_queue and nfetlink_log, from Eric Biederman. 7) Two liner to simplify netns logic in em_ipset_match(). 8) Add missing includes to net/net_namespace.h to avoid compilation problems that result from not including linux/netfilter.h in netns headers. 9) Use a forward declaration instead of including linux/proc_fs.h from netns/netfilter.h 10) Add a new linux/netfilter_defs.h to replace the linux/netfilter.h inclusion in netns headers. 11) Remove spurious netfilter.h file included in the net tree, also from Eric Biederman. 12) Fix x_tables compilation warnings on 32 bits platforms that resulted from recent changes in x_tables counters, from Florian Westphal. ==================== Signed-off-by: David S.
