[PATCH] nvme: Skip checking heads without namespaces

by Keith Busch

If a task is holding a reference to a namespace on a removed controller, the head will not be released. If the same controller is added again later, its namespaces may not be successfully added. Instead, the user will see kernel message "Duplicate IDs for nsid <X>". This patch fixes that by skipping heads that don't have namespaces when considering if a new namespace is safe to add.

Build/test failures in v4.1.50

by Guenter Roeck

Hi, unfortunately I missed message that the stable release queue repository for 4.1.y changed. It looks like I am not copied on release announcements, so I missed the last couple of releases. As a result, my builders did not catch any changes for some time. I just ran a test on v4.1.50 and got the following results. Build results: total: 139 pass: 133 fail: 6 Failed builds: arm:axm55xx_defconfig arm64:allmodconfig i386:defconfig i386:allyesconfig i386:allmodconfig i386:allnoconfig Qemu test results: total: 125 pass: 111 fail: 14 Failed tests: arm64:virt:smp:defconfig:initrd arm64:xlnx-zcu102:smp:defconfig:initrd:zynqmp-ep108 arm64:virt:nosmp:defconfig:initrd arm64:xlnx-zcu102:nosmp:defconfig:initrd:zynqmp-ep108 x86:Broadwell:q35:x86_pc_defconfig x86:Skylake-Client:q35:x86_pc_defconfig x86:SandyBridge:q35:x86_pc_defconfig x86:Haswell:pc:x86_pc_defconfig x86:Nehalem:q35:x86_pc_defconfig x86:phenom:pc:x86_pc_defconfig x86:core2duo:q35:x86_pc_nosmp_defconfig x86:Conroe:isapc:x86_pc_nosmp_defconfig x86:Opteron_G1:pc:x86_pc_nosmp_defconfig x86:n270:isapc:x86_pc_nosmp_defconfig From the logs: Building arm:axm55xx_defconfig ... failed -------------- Error log: arch/arm/kvm/handle_exit.c: In function 'handle_hvc': arch/arm/kvm/handle_exit.c:48:3: error: implicit declaration of function 'vcpu_set_reg' Building arm64:allmodconfig ... failed -------------- Error log: arch/arm64/kvm/handle_exit.c:45:3: error: implicit declaration of function ‘vcpu_set_reg’; did you mean ‘vcpu_sys_reg’?

[PATCH 1/6] mm/vmscan: Wake up flushers for legacy cgroups too

by Andrey Ryabinin

Commit 726d061fbd36 ("mm: vmscan: kick flushers when we encounter dirty pages on the LRU") added flusher invocation to shrink_inactive_list() when many dirty pages on the LRU are encountered. However, shrink_inactive_list() doesn't wake up flushers for legacy cgroup reclaim, so the next commit bbef938429f5 ("mm: vmscan: remove old flusher wakeup from direct reclaim path") removed the only source of flusher's wake up in legacy mem cgroup reclaim path. This leads to premature OOM if there is too many dirty pages in cgroup: # mkdir /sys/fs/cgroup/memory/test # echo $$ > /sys/fs/cgroup/memory/test/tasks # echo 50M > /sys/fs/cgroup/memory/test/memory.limit_in_bytes # dd if=/dev/zero of=tmp_file bs=1M count=100 Killed dd invoked oom-killer: gfp_mask=0x14000c0(GFP_KERNEL), nodemask=(null), order=0, oom_score_adj=0 Call Trace: dump_stack+0x46/0x65 dump_header+0x6b/0x2ac oom_kill_process+0x21c/0x4a0 out_of_memory+0x2a5/0x4b0 mem_cgroup_out_of_memory+0x3b/0x60 mem_cgroup_oom_synchronize+0x2ed/0x330 pagefault_out_of_memory+0x24/0x54 __do_page_fault+0x521/0x540 page_fault+0x45/0x50 Task in /test killed as a result of limit of /test memory: usage 51200kB, limit 51200kB, failcnt 73 memory+swap: usage 51200kB, limit 9007199254740988kB, failcnt 0 kmem: usage 296kB, limit 9007199254740988kB, failcnt 0 Memory cgroup stats for /test: cache:49632KB rss:1056KB rss_huge:0KB shmem:0KB mapped_file:0KB dirty:49500KB writeback:0KB swap:0KB inactive_anon:0KB active_anon:1168KB inactive_file:24760KB active_file:24960KB unevictable:0KB Memory cgroup out of memory: Kill process 3861 (bash) score 88 or sacrifice child Killed process 3876 (dd) total-vm:8484kB, anon-rss:1052kB, file-rss:1720kB, shmem-rss:0kB oom_reaper: reaped process 3876 (dd), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB Wake up flushers in legacy cgroup reclaim too.

Interesting, I also experienced a spontaneous panic on my home firewall after upgrading it from 4.14.10 to 4.14.27, but I didn't have any symbol in the traces so the dump wasn't exploitable. All I know is that it was a NULL deref with a very small offset as well. It may be totally unrelated though but the coincidence is troubling, especially since I haven't had a panic in -stable for a very long time. Ah I've just seen your second e-mail. So if it's the same as the patch you pointed, the bug is 4.14-only and the fix as well. It will likely come with the next batch of networking backports. Cheers, Willy

[Linux-stable-mirror] [PATCH] thermal: imx: Fix race condition in imx_thermal_probe()

by Fabio Estevam

From: Mikhail Lappo <mikhail.lappo(a)esrlabs.com> When device boots with T > T_trip_1 and requests interrupt, the race condition takes place. The interrupt comes before THERMAL_DEVICE_ENABLED is set. This leads to an attempt to reading sensor value from irq and disabling the sensor, based on the data->mode field, which expected to be THERMAL_DEVICE_ENABLED, but still stays as THERMAL_DEVICE_DISABLED. Afher this issue sensor is never re-enabled, as the driver state is wrong. Fix this problem by setting the 'data' members prior to requesting the interrupts.

patch "phy: allwinner: sun4i-usb: poll vbus changes on A23/A33 when driving" added to usb-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled phy: allwinner: sun4i-usb: poll vbus changes on A23/A33 when driving to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From d7119224bfe6e8efbf821a52db7da9530d790f07 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai <wens(a)csie.org> Date: Fri, 19 Jan 2018 17:25:41 +0800 Subject: phy: allwinner: sun4i-usb: poll vbus changes on A23/A33 when driving VBUS The AXP223 PMIC, like the AXP221, does not generate VBUS change interrupts when N_VBUSEN is used to drive VBUS for the OTG port on the board. This was not noticed until recently, as most A23/A33 boards use a GPIO pin that does not support interrupts for OTG ID detection. This forces the driver to use polling. However the A33-OlinuXino uses a pin that does support interrupts, so the driver uses them. However the VBUS interrupt never fires, and the driver never gets to update the VBUS status. This results in musb timing out waiting for VBUS to rise. This was worked around for the AXP221 by resorting to polling changes in commit 91d96f06a760 ("phy-sun4i-usb: Add workaround for missing Vbus det interrupts on A31"). This patch adds the A23 and A33 to the list of SoCs that need the workaround.

[PATCH][v2] mtd: rawnand: fsl_ifc: Fix nand waitfunc return value

by Jagdish Gediya

As per the IFC hardware manual, Most significant 2 bytes in nand_fsr register are the outcome of NAND READ STATUS command. So status value need to be shifted and aligned as per the nand framework requirement.
