But the SLUB code is relatively lockless, and the spin_locks there are raw_spin_locks (not converted to mutexes), thus I believe this bug can happen in mainline without -rt features. The -rt patch is just good at triggering mainline bugs ;-) Anyway, looking at where this crashed, it seems that the page variable can be NULL when passed to the node_match() function (which does not check if it is NULL). When this happens we get the above panic. As page is only used in slab_alloc() to check if the node matches, if it's NULL I'm assuming that we can say it doesn't and call the __slab_alloc() code. Is this a correct assumption?

e9a17bd Oleg Nesterov 08 July 2013, 21:24:19 UTC llist: llist_add() can use llist_add_batch() llist_add(new, head) can simply use llist_add_batch(new, new, head), no need to duplicate the code. This obviously uninlines llist_add() and to me this is a win. But we can make llist_add_batch() inline if this is desirable, in this case gcc can notice that new_first == new_last if the caller is llist_add().

fb4214d Oleg Nesterov 08 July 2013, 21:24:18 UTC llist: fix/simplify llist_add() and llist_add_batch() 1. This is mostly theoretical, but llist_add*() need ACCESS_ONCE(). Otherwise it is not guaranteed that the first cmpxchg() uses the same value for old_entry and new_last->next. 2. These helpers cache the result of cmpxchg() and read the initial value of head->first before the main loop. I do not think this makes sense. In the likely case cmpxchg() succeeds, otherwise it doesn't hurt to reload head->first. I think it would be better to simplify the code and simply read ->first before cmpxchg().

307f2fb Hannes Frederic Sowa 12 July 2013, 21:46:33 UTC ipv6: only static routes qualify for equal cost multipathing Static routes in this case are non-expiring routes which did not get configured by autoconf or by icmpv6 redirects. To make sure we actually get an ecmp route while searching for the first one in this fib6_node's leafs, also make sure it matches the ecmp route assumptions. v2: a) Removed RTF_EXPIRE check in dst.from chain. The check of RTF_ADDRCONF already ensures that this route, even if added again without RTF_EXPIRES (in case of a RA announcement with infinite timeout), does not cause the rt6i_nsiblings logic to go wrong if a later RA updates the expiration time later. v3: a) Allow RTF_EXPIRES routes to enter the ecmp route set. We have to do so, because an pmtu event could update the RTF_EXPIRES flag and we would not count this route, if another route joins this set. We now filter only for RTF_GATEWAY|RTF_ADDRCONF|RTF_DYNAMIC, which are flags that don't get changed after rt6_info construction.

The hrtimer code only needs this when we accidentally try to program an expired time. We don't much care about those anyway since we have the regular tick to fall back to.

a272dcc Stephen Boyd 11 July 2013, 14:00:59 UTC tick: broadcast: Check broadcast mode on CPU hotplug On ARM systems the dummy clockevent is registered with the cpu hotplug notifier chain before any other per-cpu clockevent. This has the side-effect of causing the dummy clockevent to be registered first in every hotplug sequence. Because the dummy is first, we'll try to turn the broadcast source on but the code in tick_device_uses_broadcast() assumes the broadcast source is in periodic mode and calls tick_broadcast_start_periodic() unconditionally. On boot this isn't a problem because we typically haven't switched into oneshot mode yet (if at all). During hotplug, if the broadcast source isn't in periodic mode we'll replace the broadcast oneshot handler with the broadcast periodic handler and start emulating oneshot mode when we shouldn't. Due to the way the broadcast oneshot handler programs the next_event it's possible for it to contain KTIME_MAX and cause us to hang the system when the periodic handler tries to program the next tick. Fix this by using the appropriate function to start the broadcast source.

The reason is that there's a time window between the 'ctx->is_active' check in the perf_event_enable() function and the __perf_event_enable() function having: - IRQs on - ctx->lock unlocked where the task could be killed and 'ctx' deactivated by perf_event_exit_task(), ending up with the warning below.

8c91e16 Alexander Duyck 11 July 2013, 20:12:22 UTC gre: Fix MTU sizing check for gretap tunnels This change fixes an MTU sizing issue seen with gretap tunnels when non-gso packets are sent from the interface. In my case I was able to reproduce the issue by simply sending a ping of 1421 bytes with the gretap interface created on a device with a standard 1500 mtu. This fix is based on the fact that the tunnel mtu is already adjusted by dev->hard_header_len so it would make sense that any packets being compared against that mtu should also be adjusted by hard_header_len and the tunnel header instead of just the tunnel header.

The check made sense in Irix, but in Linux, quota is turned off one at a time, which makes the test invalid for Linux. This problem existed since XFS was ported to Linux. David suggested to fix the problem by detecting when all quotas are turned off by checking m_qflags.

87f1369 Paolo Valente 10 July 2013, 13:46:08 UTC pkt_sched: sch_qfq: improve efficiency of make_eligible In make_eligible, a mask is used to decide which groups must become eligible: the i-th group becomes eligible only if the i-th bit of the mask (from the right) is set. The mask is computed by left-shifting a 1 by a given number of places, and decrementing the result. The shift is performed on a ULL to avoid problems in case the number of places to shift is higher than 31. On a 32-bit machine, this is more costly than working on an UL. This patch replaces such a costly operation with two cheaper branches. The trick is based on the following fact: in case of a shift of at least 32 places, the resulting mask has at least the 32 less significant bits set, whereas the total number of groups is lower than 32. As a consequence, in this case it is enough to just set the 32 less significant bits of the mask with a cheaper ~0UL. In the other case, the shift can be safely performed on a UL.

This driver registers CPU digital temperature package level sensor as a thermal zone. - small fixes/cleanups including removing redundant use of platform_set_drvdata() and of_match_ptr for all platform thermal drivers" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: (34 commits) thermal: cpu_cooling: fix stub function thermal: ti-soc-thermal: use standard GPIO DT bindings thermal: MAINTAINERS: Add git tree path for SoC specific updates thermal: fix x86_pkg_temp_thermal.c build and Kconfig Thermal: Documentation for x86 package temperature thermal driver Thermal: CPU Package temperature thermal thermal: consider emul_temperature while computing trend thermal: ti-soc-thermal: add DT example for DRA752 chip thermal: ti-soc-thermal: add dra752 chip to device table thermal: ti-soc-thermal: add thermal data for DRA752 chips thermal: ti-soc-thermal: remove usage of IS_ERR_OR_NULL thermal: ti-soc-thermal: freeze FSM while computing trend thermal: ti-soc-thermal: remove external heat while extrapolating hotspot thermal: ti-soc-thermal: update DT reference for OMAP5430 x86, mcheck, therm_throt: Process package thresholds thermal: cpu_cooling: fix 'descend' check in get_property() Thermal: spear: Remove redundant use of of_match_ptr Thermal: kirkwood: Remove redundant use of of_match_ptr Thermal: dove: Remove redundant use of of_match_ptr Thermal: armada: Remove redundant use of of_match_ptr ... 11 July 2013, 19:26:08 UTC
cdbaa0b Alexander Duyck 11 July 2013, 00:05:06 UTC gso: Update tunnel segmentation to support Tx checksum offload This change makes it so that the GRE and VXLAN tunnels can make use of Tx checksum offload support provided by some drivers via the hw_enc_features. Without this fix enabling GSO means sacrificing Tx checksum offload and this actually leads to a performance regression as shown below: Utilization Send Throughput local GSO 10^6bits/s % S state 6276.51 8.39 enabled 7123.52 8.42 disabled To resolve this it was necessary to address two items. First netif_skb_features needed to be updated so that it would correctly handle the Trans Ether Bridging protocol without impacting the need to check for Q-in-Q tagging. To do this it was necessary to update harmonize_features so that it used skb_network_protocol instead of just using the outer protocol. Second it was necessary to update the GRE and UDP tunnel segmentation offloads so that they would reset the encapsulation bit and inner header offsets after the offload was complete. As a result of this change I have seen the following results on a interface with Tx checksum enabled for encapsulated frames: Utilization Send Throughput local GSO 10^6bits/s % S state 7123.52 8.42 disabled 8321.75 5.43 enabled v2: Instead of replacing refrence to skb->protocol with skb_network_protocol just replace the protocol reference in harmonize_features to allow for double VLAN tag checks.

fcf9567 Hector Palacios 08 April 2013, 15:06:32 UTC watchdog: core: don't try to stop device if not running A watchdog device may be stopped from userspace using WDIOC_SETOPTIONS ioctl and flag WDIOS_DISABLECARD. If the device is closed after this operation, watchdog_release() is called and status bits checked for stopping it. Besides, if the device has not been unregistered a critical message "watchdog did not stop!" is printed, although the ioctl may have successfully stopped it already. Without the patch a user application sample code like this will successfully stop the watchdog, but the kernel will output the message "watchdog did not stop!": wd_fd = open("/dev/watchdog", O_RDWR); flags = WDIOS_DISABLECARD; ioctl(wd_fd, WDIOC_SETOPTIONS, &flags); close(wd_fd); Signed-off-by: Hector Palacios <hector.palacios@digi.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> 11 July 2013, 19:14:39 UTC
