d01552a | NeilBrown | 31 October 2015, 00:00:56 UTC | Revert "md: allow a partially recovered device to be hot-added to an array." This reverts commit 7eb418851f3278de67126ea0c427641ab4792c57. This commit is poorly justified, I can find not discusison in email, and it clearly causes a problem. If a device which is being recovered fails and is subsequently re-added to an array, there could easily have been changes to the array *before* the point where the recovery was up to. So the recovery must start again from the beginning. If a spare is being recovered and fails, then when it is re-added we really should do a bitmap-based recovery up to the recovery-offset, and then a full recovery from there. Before this reversion, we only did the "full recovery from there" which is not corect. After this reversion with will do a full recovery from the start, which is safer but not ideal. It will be left to a future patch to arrange the two different styles of recovery.

b8a9d66 | Roman Gushchin | 30 October 2015, 23:53:50 UTC | md/raid5: fix locking in handle_stripe_clean_event() After commit 566c09c53455 ("raid5: relieve lock contention in get_active_stripe()") __find_stripe() is called under conf->hash_locks + hash. But handle_stripe_clean_event() calls remove_hash() under conf->device_lock. Under some cirscumstances the hash chain can be circuited, and we get an infinite loop with disabled interrupts and locked hash lock in __find_stripe(). This leads to hard lockup on multiple CPUs and following system crash. I was able to reproduce this behavior on raid6 over 6 ssd disks. The devices_handle_discard_safely option should be set to enable trim support. The following script was used: for i in `seq 1 32`; do dd if=/dev/zero of=large$i bs=10M count=100 & done neilb: original was against a 3.x kernel. I forward-ported to 4.3-rc.

But since kernel 3.9 (patch 1d1d1a767206fbe5d4c69493b7e6d2a8d08cc0a0 "mm: only enforce stable page writes if the backing device requires it") it is not assumed anymore that block devices require stable pages. This patch sets the necessary flag to get stable pages back for rbd. In a ceph installation that provides multiple ext4 formatted rbd devices "bad crc" messages appeared regularly (ca 1 message every 1-2 minutes on every OSD that provided the data for the rbd) in the OSD-logs before this patch. After this patch this messages are pretty much gone (only ca 1-2 / month / OSD).

In case we need to fragment those packets, we reparse the options header to find the place where we can insert the fragment header. If the extension headers exceed the link's MTU we actually cannot make progress in such a case. Instead of ending up in broken arithmetic or rounding towards 0 and entering an endless loop in ip6_fragment, just prevent those cases by aborting early and signal -EMSGSIZE to user space.

This however caused a regression for MUSB omap2430 interface as the runtime PM for the parent device needs the child initialized to access the MUSB hardware registers. Let's delay the enabling of PM runtime for the parent until the child has been properly initialized as suggested in an earlier patch by Grygorii Strashko <grygorii.strashko@ti.com>. In addition to delaying pm_runtime_enable, we now also need to make sure the parent is enabled during omap2430_musb_init. We also want to propagate an error from omap2430_runtime_resume if struct musb is not initialized. Note that we use pm_runtime_put_noidle here for both the child and parent to prevent an extra runtime_suspend/resume cycle. Let's also add some comments to avoid confusion between the two different devices.

With this patch applied, we were the only architecture making this sort of adjustment to the PC calculation in the unwinder. This causes problems for ftrace, where the PC values are matched against the contents of the stack frames in the callchain and fail to match any records after the address adjustment. Whilst there has been some effort to change ftrace to workaround this, those patches are not yet ready for mainline and, since we're the odd architecture in this regard, let's just step in line with other architectures (like arch/arm/) for now.

e13d918 | Lorenzo Pieralisi | 27 October 2015, 17:29:10 UTC | arm64: kernel: fix tcr_el1.t0sz restore on systems with extended idmap Commit dd006da21646 ("arm64: mm: increase VA range of identity map") introduced a mechanism to extend the virtual memory map range to support arm64 systems with system RAM located at very high offset, where the identity mapping used to enable/disable the MMU requires additional translation levels to map the physical memory at an equal virtual offset. The kernel detects at boot time the tcr_el1.t0sz value required by the identity mapping and sets-up the tcr_el1.t0sz register field accordingly, any time the identity map is required in the kernel (ie when enabling the MMU). After enabling the MMU, in the cold boot path the kernel resets the tcr_el1.t0sz to its default value (ie the actual configuration value for the system virtual address space) so that after enabling the MMU the memory space translated by ttbr0_el1 is restored as expected. Commit dd006da21646 ("arm64: mm: increase VA range of identity map") also added code to set-up the tcr_el1.t0sz value when the kernel resumes from low-power states with the MMU off through cpu_resume() in order to effectively use the identity mapping to enable the MMU but failed to add the code required to restore the tcr_el1.t0sz to its default value, when the core returns to the kernel with the MMU enabled, so that the kernel might end up running with tcr_el1.t0sz value set-up for the identity mapping which can be lower than the value required by the actual virtual address space, resulting in an erroneous set-up. This patchs adds code in the resume path that restores the tcr_el1.t0sz default value upon core resume, mirroring this way the cold boot path behaviour therefore fixing the issue.

If caps.eqe_size is bigger than the struct mlx4_eqe then we corrupt data in the master context. When using a 64 byte stride, the memcpy copied over 63 bytes to the slave_eq structure. This resulted in copying over the entire eqe of interest, including its ownership bit -- and also 31 bytes of garbage into the next WQE in the slave EQ -- which did NOT include the ownership bit (and therefore had no impact). However, once the stride is increased to 128, we are overwriting the ownership bits of *three* eqes in the slave_eq struct. This results in an incorrect ownership bit for those eqes, which causes the eq to seem to be full. The issue therefore surfaced only once 128-byte EQEs started being used in SRIOV and (overarchitectures that have 128/256 byte cache-lines such as PPC) - e.g after commit 77507aa249ae "net/mlx4_core: Enable CQE/EQE stride support".

This causes errant warnings in the netpoll path as in netpoll_send_skb_on_dev, where we disable irqs using local_irq_save, leading to the following warning: WARNING: at net/core/netpoll.c:352 netpoll_send_skb_on_dev+0x243/0x250() (Not tainted) Hardware name: netpoll_send_skb_on_dev(): eth0 enabled interrupts in poll (nv_start_xmit_optimized+0x0/0x860 [forcedeth]) Modules linked in: netconsole(+) configfs ipv6 iptable_filter ip_tables ppdev parport_pc parport sg microcode serio_raw edac_core edac_mce_amd k8temp snd_hda_codec_realtek snd_hda_codec_generic forcedeth snd_hda_intel snd_hda_codec snd_hwdep snd_seq snd_seq_device snd_pcm snd_timer snd soundcore snd_page_alloc i2c_nforce2 i2c_core shpchp ext4 jbd2 mbcache sr_mod cdrom sd_mod crc_t10dif pata_amd ata_generic pata_acpi sata_nv dm_mirror dm_region_hash dm_log dm_mod [last unloaded: scsi_wait_scan] Pid: 1940, comm: modprobe Not tainted 2.6.32-573.7.1.el6.x86_64.debug #1 Call Trace: [<ffffffff8107bbc1>] ? warn_slowpath_common+0x91/0xe0 [<ffffffff8107bcc6>] ? warn_slowpath_fmt+0x46/0x60 [<ffffffffa00fe5b0>] ? nv_start_xmit_optimized+0x0/0x860 [forcedeth] [<ffffffff814b3593>] ? netpoll_send_skb_on_dev+0x243/0x250 [<ffffffff814b37c9>] ? netpoll_send_udp+0x229/0x270 [<ffffffffa02e3299>] ? write_msg+0x39/0x110 [netconsole] [<ffffffffa02e331b>] ? write_msg+0xbb/0x110 [netconsole] [<ffffffff8107bd55>] ? __call_console_drivers+0x75/0x90 [<ffffffff8107bdba>] ? _call_console_drivers+0x4a/0x80 [<ffffffff8107c445>] ? release_console_sem+0xe5/0x250 [<ffffffff8107d200>] ? register_console+0x190/0x3e0 [<ffffffffa02e71a6>] ? init_netconsole+0x1a6/0x216 [netconsole] [<ffffffffa02e7000>] ? init_netconsole+0x0/0x216 [netconsole] [<ffffffff810020d0>] ? do_one_initcall+0xc0/0x280 [<ffffffff810d4933>] ? sys_init_module+0xe3/0x260 [<ffffffff8100b0d2>] ? system_call_fastpath+0x16/0x1b ---[ end trace f349c7af88e6a6d5 ]--- console [netcon0] enabled netconsole: network logging started Fix it by modifying the forcedeth code to use disable_irq_nosync_lockdep_irqsavedisable_irq_nosync_lockdep_irqsave instead, which saves and restores irq state properly.

6f5cade | Joe Stringer | 26 October 2015, 03:21:50 UTC | openvswitch: Fix skb leak using IPv6 defrag nf_ct_frag6_gather() makes a clone of each skb passed to it, and if the reassembly is successful, expects the caller to free all of the original skbs using nf_ct_frag6_consume_orig(). This call was previously missing, meaning that the original fragments were never freed (with the exception of the last fragment to arrive). Fix this by ensuring that all original fragments except for the last fragment are freed via nf_ct_frag6_consume_orig(). The last fragment will be morphed into the head, so it must not be freed yet. Furthermore, retain the ->next pointer for the head after skb_morph().

a22c4d7 | Ming Lin | 22 October 2015, 16:59:42 UTC | block: re-add discard_granularity and alignment checks In commit b49a087("block: remove split code in blkdev_issue_{discard,write_same}"), discard_granularity and alignment checks were removed. Ideally, with bio late splitting, the upper layers shouldn't need to depend on device's limits. Christoph reported a discard regression on the HGST Ultrastar SN100 NVMe device when mkfs.xfs. We have not found the root cause yet. This patch re-adds discard_granularity and alignment checks by reverting the related changes in commit b49a087. The good thing is now we can remove the 2G discard size cap and just use UINT_MAX to avoid bi_size overflow.

1955621 | Hans de Goede | 26 October 2015, 08:50:28 UTC | Input: alps - only the Dell Latitude D420/430/620/630 have separate stick button bits commit 92bac83dd79e ("Input: alps - non interleaved V2 dualpoint has separate stick button bits") assumes that all alps v2 non-interleaved dual point setups have the separate stick button bits. Later we limited this to Dell laptops only because of reports that this broke things on non Dell laptops. Now it turns out that this breaks things on the Dell Latitude D600 too. So it seems that only the Dell Latitude D420/430/620/630, which all share the same touchpad / stick combo, have these separate bits. This patch limits the checking of the separate bits to only these models fixing regressions with other models.

That results in a NULL pointer dereference for the rare case where the underlying irq chip is lapic_chip which has no irq_set_affinity() callback. lapic_chip is occasionally used for the timer interrupt (irq 0). The fix is simple: Check the availability of the callback instead of calling it unconditionally.

182475b | Dan Williams | 26 October 2015, 20:55:56 UTC | memremap: fix highmem support Currently memremap checks if the range is "System RAM" and returns the kernel linear address. This is broken for highmem platforms where a range may be "System RAM", but is not part of the kernel linear mapping. Fallback to ioremap_cache() in these cases, to let the arch code attempt to handle it. Note that ARM ioremap will WARN when attempting to remap ram, and in that case the caller needs to be fixed. For this reason, existing ioremap_cache() usages for ARM are already trained to avoid attempts to remap ram. The impact of this bug is low for now since the pmem driver is the only user of memremap(), but this is important to fix before more conversions to memremap arrive in 4.4. Cc: Rafael J.

Use the right counter. BSY conditions happen when the SoC is under performance stress. Doing *more* work in stress situations by trying to schedule NAPI is not a good idea as the stressed system becomes still more stressed. The Rx interrupt is already at work making sure the NAPI is scheduled. So calling gfar_receive() here does not help. This issue was present since day 1.

With the default config this does not happen because the default Rx offloads (Rx csum and Rx VLAN) properly enable PRSDEP. But if anyone disables all these offloads (via ethtool), we get a wrong configuration were the Rx flow classification and hashing, and other Filer based features (e.g. wake-on-filer interrupt) won't work.

353d6d6 | Thomas Petazzoni | 21 October 2015, 13:48:15 UTC | irqchip/armada-370-xp: Fix regression by clearing IRQ_NOAUTOEN Commit d17cab4451df1 ("irqchip: Kill off set_irq_flags usage") changed the code of armada_370_xp_mpic_irq_map() from using set_irq_flags() to irq_set_probe(). While the commit log seems to imply that there are no functional changes, there are indeed functional changes introduced by this commit: the IRQ_NOAUTOEN flag is no longer cleared. This functional change causes a regression on Armada XP, which no longer works properly after suspend/resume because per-CPU interrupts remain disabled. Due to how the hardware registers work, the irq-armada-370-xp cannot simply save/restore a bunch of registers at suspend/resume to make sure that the interrupts remain in the same state after resuming. Therefore, it relies on the kernel to say whether the interrupt is disabled or not, using the irqd_irq_disabled() function. This was all working fine while the IRQ_NOAUTOEN flag was cleared. With the change introduced by Rob Herring in d17cab4451df1, the IRQ_NOAUTOEN flag is now set for all interrupts. irqd_irq_disabled() returns false for per-CPU interrupts, and therefore our per-CPU interrupts are no longer re-enabled after resume. This commit works around this problem by clearing again the IRQ_NOAUTOEN flags, so that we are back to the situation we had before commit d17cab4451df1. This work around is proposed as a minimal fix for the problem, while a better long-term solution is being worked on.
