[PATCH v2] block: Change a rcu_read_{lock, unlock}_sched() pair into rcu_read_{lock, unlock}()

by Bart Van Assche

scsi_device_quiesce() uses synchronize_rcu() to guarantee that the effect of blk_set_preempt_only() will be visible for percpu_ref_tryget() calls that occur after the queue unfreeze by using the approach explained in https://lwn.net/Articles/573497/. The rcu read lock and unlock calls in blk_queue_enter() form a pair with the synchronize_rcu() call in scsi_device_quiesce(). Both scsi_device_quiesce() and blk_queue_enter() must either use regular RCU or RCU-sched. Since neither the RCU-protected code in blk_queue_enter() nor blk_queue_usage_counter_release() sleeps, regular RCU protection is sufficient. Note: scsi_device_quiesce() does not have to be modified since it already uses synchronize_rcu().

patch "staging: comedi: ni_mio_common: ack ai fifo error interrupts." added to staging-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled staging: comedi: ni_mio_common: ack ai fifo error interrupts. to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-testing 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 be merged to the staging-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From e1d9fc04c41840a4688ef6ce90b6dcca157ea4d7 Mon Sep 17 00:00:00 2001 From: Frank Mori Hess <fmh6jj(a)gmail.com> Date: Thu, 15 Mar 2018 10:25:44 +0000 Subject: staging: comedi: ni_mio_common: ack ai fifo error interrupts.

[PATCH] xprtrdma: Fix corner cases when handling device removal

by Chuck Lever

Michal Kalderon has found some corner cases around device unload with active NFS mounts that I didn't have the imagination to test when xprtrdma device removal was added last year. - The ULP device removal handler is responsible for deallocating the PD. That wasn't clear to me initially, and my own testing suggested it was not necessary, but that is incorrect. - The transport destruction path can no longer assume that there is a valid ID. - When destroying a transport, ensure that ib_free_cq() is not invoked on a CQ that was already released.

requesting stable backport for 4.1 and 4.4: 95a762e2c8c9 ("bpf: fix incorrect sign extension in check_alu_op()")

by Jann Horn

Hi! Someone on Twitter (https://twitter.com/vnik5287/status/974277953394651137) is pointing out that the BPF fix commit 95a762e2c8c942780948091f8f2a4f32fce1ac6f ("bpf: fix incorrect sign extension in check_alu_op()") needs to be applied all the way back to 4.4, and probably also 4.1; my "Fixes:" tag on that commit is incorrect. I assumed that without map access, math correctness issues don't matter, but actually, this one does matter because check_cond_jmp_op() will omit verification for branches that appear to be unreachable (comparison of CONST_IMM register and a constant value). :/ FWIW, I checked by hand what the binary blob of BPF code in the linked PoC does, and it's basically this (with some error checking and other minor stuff omitted): // trick the verifier into not checking any of the code below r9 = (u32)-1 if (r9 == (s32)-1) exit 0 // read some configuration r6 = *map_lookup_elem(MAP_FD, &0) // operation selector r7 = *map_lookup_elem(MAP_FD, &1) // pointer to access r8 = *map_lookup_elem(MAP_FD, &2) // value to write r2 = map_lookup_elem(MAP_FD, &2) if r6 == 0: // operation: read r3 = *r7 *r2 = r3 exit if r6 == 1: // operation: get frame pointer *r2 = fp exit *r7 = r8 // operation: write exit The author of the tweet does point out that this exploit is mitigated by sanitize_dead_code() (introduced in "bpf: fix branch pruning logic" and backported all the way), but 95a762e2c8c9 should still be applied.

Commit 689bf72c6e0d ("usb: dwc3: Don't reinitialize core during host bus-suspend/resume") updated suspend/resume routines to not power_off and reinit PHYs/core for host mode. It broke platforms that rely on DWC3 core to power_off PHYs to enter low power state on system suspend. Perform dwc3_core_exit/init only during host mode system_suspend/ resume to addresses power regression from above mentioned patch and also allow USB session to stay connected across runtime_suspend/resume in host mode. While at it also replace existing checks for HOST only dr_mode with current_dr_role to have similar core driver behavior for both Host-only and DRD+Host configurations.

Patch "scsi: qla2xxx: Fix crashes in qla2x00_probe_one on probe failure" has been added to the 4.15-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled scsi: qla2xxx: Fix crashes in qla2x00_probe_one on probe failure to the 4.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: scsi-qla2xxx-fix-crashes-in-qla2x00_probe_one-on-probe-failure.patch and it can be found in the queue-4.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 6a2cf8d3663e13e19af636c2a8d92e766261dc45 Mon Sep 17 00:00:00 2001 From: Bill Kuzeja <William.Kuzeja(a)stratus.com> Date: Mon, 5 Mar 2018 00:02:55 -0500 Subject: scsi: qla2xxx: Fix crashes in qla2x00_probe_one on probe failure From: Bill Kuzeja <William.Kuzeja(a)stratus.com> commit 6a2cf8d3663e13e19af636c2a8d92e766261dc45 upstream. Because of the shifting around of code in qla2x00_probe_one recently, failures during adapter initialization can lead to problems, i.e. NULL pointer crashes and doubly freed data structures which cause eventual panics. This V2 version makes the relevant memory free routines idempotent, so repeat calls won't cause any harm. I also removed the problematic probe_init_failed exit point as it is not needed.

This is caused by a bug in the BDC core. When the BDC core comes out of reset and it's not selected, it gets a backup clock. When the BDC core is selected, it get's the main clock. If HOST mode is then selected the BDC core has the main clock shut off but the backup clock is not restored. The failure scenario and cause are as follows: - DRD mode is active - Device mode is selected first in bootloader - When host mode is now selected, the clock to the BDC is cut off. - BDC registers are inaccessible and therefore the BDC driver crashes upon Linux boot. The fix is to have the phy driver always force a BDC reset on startup.
