Suzuki K Poulose 502bd98a8e coresight: etm4x: Fix use-after-free of per-cpu etm drvdata [ Upstream commit 3f4943d422c5febbb3c764670011a00eb2a86238 ] etm probe could be deferred due to the dependency in the trace path chain and may be retried. We need to clear the per-cpu etmdrvdata entry for the etm in case of a failure to avoid use-after-free cases as reported below: KASAN use-after-free bug in etm4_cpu_pm_notify(): [ 8.574566] coresight etm0: CPU0: ETM v4.2 initialized [ 8.581920] BUG: KASAN: use-after-free in etm4_cpu_pm_notify+0x580/0x2024 [ 8.581925] Read of size 8 at addr ffffff813304f8c8 by task swapper/3/0 [ 8.581927] [ 8.581934] CPU: 3 PID: 0 Comm: swapper/3 Tainted: G S W 5.4.28 #314 [ 8.587775] coresight etm1: CPU1: ETM v4.2 initialized [ 8.594195] Call trace: [ 8.594205] dump_backtrace+0x0/0x188 [ 8.594209] show_stack+0x20/0x2c [ 8.594216] dump_stack+0xdc/0x144 [ 8.594227] print_address_description+0x3c/0x494 [ 8.594232] __kasan_report+0x144/0x168 [ 8.601598] coresight etm2: CPU2: ETM v4.2 initialized [ 8.602563] kasan_report+0x10/0x18 [ 8.602568] check_memory_region+0x1a4/0x1b4 [ 8.602572] __kasan_check_read+0x18/0x24 [ 8.602577] etm4_cpu_pm_notify+0x580/0x2024 [ 8.665945] notifier_call_chain+0x5c/0x90 [ 8.670166] __atomic_notifier_call_chain+0x90/0xf8 [ 8.675182] cpu_pm_notify+0x40/0x6c [ 8.678858] cpu_pm_enter+0x38/0x80 [ 8.682451] psci_enter_idle_state+0x34/0x70 [ 8.686844] cpuidle_enter_state+0xb8/0x20c [ 8.691143] cpuidle_enter+0x38/0x4c [ 8.694820] call_cpuidle+0x3c/0x68 [ 8.698408] do_idle+0x1a0/0x280 [ 8.701729] cpu_startup_entry+0x24/0x28 [ 8.705768] secondary_start_kernel+0x15c/0x170 [ 8.710423] [ 8.711972] Allocated by task 242: [ 8.715473] __kasan_kmalloc+0xf0/0x1ac [ 8.719426] kasan_slab_alloc+0x14/0x1c [ 8.723375] __kmalloc_track_caller+0x23c/0x388 [ 8.728040] devm_kmalloc+0x38/0x94 [ 8.731632] etm4_probe+0x48/0x3c8 [ 8.735140] amba_probe+0xbc/0x158 [ 8.738645] really_probe+0x144/0x408 [ 8.742412] driver_probe_device+0x70/0x140 [ 8.746716] __device_attach_driver+0x9c/0x110 [ 8.751287] bus_for_each_drv+0x90/0xd8 [ 8.755236] __device_attach+0xb4/0x164 [ 8.759188] device_initial_probe+0x20/0x2c [ 8.763490] bus_probe_device+0x34/0x94 [ 8.767436] device_add+0x34c/0x3e0 [ 8.771029] amba_device_try_add+0x68/0x440 [ 8.775332] amba_deferred_retry_func+0x48/0xc8 [ 8.779997] process_one_work+0x344/0x648 [ 8.784127] worker_thread+0x2ac/0x47c [ 8.787987] kthread+0x128/0x138 [ 8.791313] ret_from_fork+0x10/0x18 [ 8.794993] [ 8.796532] Freed by task 242: [ 8.799684] __kasan_slab_free+0x15c/0x22c [ 8.803897] kasan_slab_free+0x10/0x1c [ 8.807761] kfree+0x25c/0x4bc [ 8.810913] release_nodes+0x240/0x2b0 [ 8.814767] devres_release_all+0x3c/0x54 [ 8.818887] really_probe+0x178/0x408 [ 8.822661] driver_probe_device+0x70/0x140 [ 8.826963] __device_attach_driver+0x9c/0x110 [ 8.831539] bus_for_each_drv+0x90/0xd8 [ 8.835487] __device_attach+0xb4/0x164 [ 8.839431] device_initial_probe+0x20/0x2c [ 8.843732] bus_probe_device+0x34/0x94 [ 8.847678] device_add+0x34c/0x3e0 [ 8.851274] amba_device_try_add+0x68/0x440 [ 8.855576] amba_deferred_retry_func+0x48/0xc8 [ 8.860240] process_one_work+0x344/0x648 [ 8.864366] worker_thread+0x2ac/0x47c [ 8.868228] kthread+0x128/0x138 [ 8.871557] ret_from_fork+0x10/0x18 [ 8.875231] [ 8.876782] The buggy address belongs to the object at ffffff813304f800 [ 8.876782] which belongs to the cache kmalloc-1k of size 1024 [ 8.889632] The buggy address is located 200 bytes inside of [ 8.889632] 1024-byte region [ffffff813304f800, ffffff813304fc00) [ 8.901761] The buggy address belongs to the page: [ 8.906695] page:ffffffff04ac1200 refcount:1 mapcount:0 mapping:ffffff8146c03800 index:0x0 compound_mapcount: 0 [ 8.917047] flags: 0x4000000000010200(slab\|head) [ 8.921799] raw: 4000000000010200 dead000000000100 dead000000000122 ffffff8146c03800 [ 8.929753] raw: 0000000000000000 0000000000100010 00000001ffffffff 0000000000000000 [ 8.937703] page dumped because: kasan: bad access detected [ 8.943433] [ 8.944974] Memory state around the buggy address: [ 8.949903] ffffff813304f780: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc [ 8.957320] ffffff813304f800: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb [ 8.964742] >ffffff813304f880: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb [ 8.972157] ^ [ 8.977886] ffffff813304f900: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb [ 8.985298] ffffff813304f980: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb [ 8.992713] ================================================================== Fixes: f188b5e76aae ("coresight: etm4x: Save/restore state across CPU low power states") Reported-by: Sai Prakash Ranjan <saiprakash.ranjan@codeaurora.org> Tested-by: Sai Prakash Ranjan <saiprakash.ranjan@codeaurora.org> Cc: Mathieu Poirier <mathieu.poirier@linaro.org> Cc: Mike Leach <mike.leach@linaro.org> Signed-off-by: Suzuki K Poulose <suzuki.poulose@arm.com> Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org> Link: https://lore.kernel.org/r/20200518180242.7916-22-mathieu.poirier@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2020-10-01 13:18:02 +02:00

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
