[PATCH] xhci: Fix Kernel oops in xhci dbgtty

by Mathias Nyman

From: Zhengjun Xing <zhengjun.xing(a)linux.intel.com> tty_unregister_driver may be called more than 1 time in some hotplug cases,it will cause the kernel oops. This patch checked dbc_tty_driver to make sure it is unregistered only 1 time.

[PATCH] scsi_transport_srp: Fix shost to rport translation

by Bart Van Assche

Since an SRP remote port is attached as a child to shost->shost_gendev and as the only child, the translation from the shost pointer into an rport pointer must happen by looking up the shost child that is an rport. This patch fixes the following KASAN complaint: BUG: KASAN: slab-out-of-bounds in srp_timed_out+0x57/0x110 [scsi_transport_srp] Read of size 4 at addr ffff880035d3fcc0 by task kworker/1:0H/19 CPU: 1 PID: 19 Comm: kworker/1:0H Not tainted 4.16.0-rc3-dbg+ #1 Workqueue: kblockd blk_mq_timeout_work Call Trace: dump_stack+0x85/0xc7 print_address_description+0x65/0x270 kasan_report+0x231/0x350 srp_timed_out+0x57/0x110 [scsi_transport_srp] scsi_times_out+0xc7/0x3f0 [scsi_mod] blk_mq_terminate_expired+0xc2/0x140 bt_iter+0xbc/0xd0 blk_mq_queue_tag_busy_iter+0x1c7/0x350 blk_mq_timeout_work+0x325/0x3f0 process_one_work+0x441/0xa50 worker_thread+0x76/0x6c0 kthread+0x1b2/0x1d0 ret_from_fork+0x24/0x30 Fixes: e68ca75200fe ("scsi_transport_srp: Reduce failover time") Signed-off-by: Bart Van Assche <bart.vanassche(a)wdc.com> Cc: Hannes Reinecke <hare(a)suse.com> Cc: Johannes Thumshirn <jthumshirn(a)suse.de> Cc: Jason Gunthorpe <jgg(a)mellanox.com> Cc: Doug Ledford <dledford(a)redhat.com> Cc: Laurence Oberman <loberman(a)redhat.com> Cc: stable(a)vger.kernel.org --- drivers/scsi/scsi_transport_srp.c | 19 ++++++++++++++++++- 1 file changed, 18 insertions(+), 1 deletion(-) diff --git a/drivers/scsi/scsi_transport_srp.c b/drivers/scsi/scsi_transport_srp.c index 36f6190931bc..0d0515615847 100644 --- a/drivers/scsi/scsi_transport_srp.c +++ b/drivers/scsi/scsi_transport_srp.c @@ -51,6 +51,8 @@ struct srp_internal { struct transport_container rport_attr_cont; }; +static int scsi_is_srp_rport(const struct device *dev); + #define to_srp_internal(tmpl) container_of(tmpl, struct srp_internal, t) #define dev_to_rport(d) container_of(d, struct srp_rport, dev) @@ -60,9 +62,24 @@ static inline struct Scsi_Host *rport_to_shost(struct srp_rport *r) return dev_to_shost(r->dev.parent); } +static int find_child_rport(struct device *dev, void *data) +{ + struct device **child = data; + + if (scsi_is_srp_rport(dev)) { + WARN_ON_ONCE(*child); + *child = dev; + } + return 0; +} + static inline struct srp_rport *shost_to_rport(struct Scsi_Host *shost) { - return transport_class_to_srp_rport(&shost->shost_gendev); + struct device *child = NULL; + + WARN_ON_ONCE(device_for_each_child(&shost->shost_gendev, &child, + find_child_rport) < 0); + return child ? dev_to_rport(child) : NULL; } /** -- 2.16.2

[PATCH] mm, slab: reschedule cache_reap() on the same CPU

by Vlastimil Babka

cache_reap() is initially scheduled in start_cpu_timer() via schedule_delayed_work_on(). But then the next iterations are scheduled via schedule_delayed_work(), i.e. using WORK_CPU_UNBOUND. Thus since commit ef557180447f ("workqueue: schedule WORK_CPU_UNBOUND work on wq_unbound_cpumask CPUs") there is no guarantee the future iterations will run on the originally intended cpu, although it's still preferred. I was able to demonstrate this with /sys/module/workqueue/parameters/debug_force_rr_cpu. IIUC, it may also happen due to migrating timers in nohz context. As a result, some cpu's would be calling cache_reap() more frequently and others never. This patch uses schedule_delayed_work_on() with the current cpu when scheduling the next iteration.

[PATCH AUTOSEL for 4.9 001/293] ALSA: timer: Wrap with spinlock for queue access

by Sasha Levin

From: Takashi Iwai <tiwai(a)suse.de> [ Upstream commit d7f910bfedd863d13ea320030fe98e42d0938ed5 ] For accessing the snd_timer_user queue indices, we take tu->qlock. But it's forgotten in a couple of places. The one in snd_timer_user_params() should be safe without the spinlock as the timer is already stopped. But it's better for consistency. The one in poll is just a read-out, so it's not inevitably needed, but it'd be good to make the result consistent, too.

[alternative-merged] resource-fix-integer-overflow-at-reallocation.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: resource: fix integer overflow at reallocation has been removed from the -mm tree. Its filename was resource-fix-integer-overflow-at-reallocation.patch This patch was dropped because an alternative patch was merged ------------------------------------------------------ From: Takashi Iwai <tiwai(a)suse.de> Subject: resource: fix integer overflow at reallocation We've got a bug report indicating a kernel panic at booting on an x86-32 system, and it turned out to be the invalid resource assigned after PCI resource reallocation. __find_resource() first aligns the resource start address and resets the end address with start+size-1 accordingly, then checks whether it's contained. Here the end address may overflow the integer, although resource_contains() still returns true because the function validates only start and end address. So this ends up with returning an invalid resource (start > end). There was already an attempt to cover such a problem in the commit 47ea91b4052d ("Resource: fix wrong resource window calculation"), but this case is an overseen one. This patch adds the validity check in resource_contains() to see whether the given resource has a valid range for avoiding the integer overflow problem.

But we have some error branches before that. In case of such an error, the code would return on the error path and trigger the calling of dma_req_free() with a req structure which is not completely initialized. This causes a NULL pointer dereference in dma_req_free(). This patch fixes these error branches by making sure that all necessary mport_dma_req structure members are initialized in rio_dma_transfer() immediately after the request structure gets allocated.
