[PATCH v2] maple_tree: Add GFP_KERNEL to allocations in mas_expected_entries()

by Liam R. Howlett

Users complained about OOM errors during fork without triggering compaction. This can be fixed by modifying the flags used in mas_expected_entries() so that the compaction will be triggered in low memory situations. Since mas_expected_entries() is only used during fork, the extra argument does not need to be passed through. Additionally, the two test_maple_tree test cases and one benchmark test were altered to use the correct locking type so that allocations would not trigger sleeping and thus fail. Testing was completed with lockdep atomic sleep detection. The additional locking change requires rwsem support additions to the tools/ directory through the use of pthreads pthread_rwlock_t. With this change test_maple_tree works in userspace, as a module, and in-kernel. Users may notice that the system gave up early on attempting to start new processes instead of attempting to reclaim memory.

Especially the static call from cleanup_trusted() led to a crash on x86 kernel with CONFIG_DEBUG_VIRTUAL=y. However, the usage of static call invocations for trusted_key_init() and trusted_key_exit() don't add any value from either a performance or security perspective. Hence switch to use indirect function calls instead. Note here that although it will fix the current crash report, ultimately the static call infrastructure should be fixed to either support its future usage from module __init and __exit functions or not.

[PATCH v2] ARM: OMAP1: ams-delta: Fix MODEM initialization failure

by Janusz Krzysztofik

Regulator drivers were modified to use asynchronous device probe. Since then, the board .init_late hook fails to acquire a GPIO based fixed regulator needed by an on-board voice MODEM device, and unregisters the MODEM. That in turn triggers a so far not discovered bug of device unregister function called for a device with no associated release() op. serial8250 serial8250.1: incomplete constraints, dummy supplies not allowed WARNING: CPU: 0 PID: 1 at drivers/base/core.c:2486 device_release+0x98/0xa8 Device 'serial8250.1' does not have a release() function, it is broken and must be fixed. See Documentation/core-api/kobject.rst. ... put_device from platform_device_put+0x1c/0x24 platform_device_put from ams_delta_init_late+0x4c/0x68 ams_delta_init_late from init_machine_late+0x1c/0x94 init_machine_late from do_one_initcall+0x60/0x1d4 As a consequence, ASoC CODEC driver is no longer able to control its device over the voice MODEM's tty interface. cx20442-codec: ASoC: error at soc_component_write_no_lock on cx20442-codec for register: [0x00000000] -5 cx20442-codec: ASoC: error at snd_soc_component_update_bits_legacy on cx20442-codec for register: [0x00000000] -5 cx20442-codec: ASoC: error at snd_soc_component_update_bits on cx20442-codec for register: [0x00000000] -5 The regulator hangs of a GPIO pin controlled by basic-mmio-gpio driver. Unlike most GPIO drivers, that driver doesn't probe for devices before device_initcall, then GPIO pins under its control are not availabele to majority of devices probed at that phase, including regulators. On the other hand, serial8250 driver used by the MODEM device neither accepts via platform data nor handles regulators, then the board file is not able to teach that driver to return -EPROBE_DEFER when the regulator is not ready so the failed probe is retried after late_initcall. Resolve the issue by extending description of the MODEM device with a dedicated power management domain. Acquire the regulator from the domain's .activate hook and return -EPROBE_DEFER if the regulator is not available. Having that under control, add the regulator device description to the list of platform devices initialized from .init_machine and drop the no longer needed custom .init_late hook. v2: Trim down the warning for prettier git log output (Tony).

[PATCH v3] nvme: fix memory corruption for passthrough metadata

by Kanchan Joshi

User can specify a smaller meta buffer than what the device is wired to update/access. Kernel makes a copy of the meta buffer into which the device does DMA. As a result, the device overwrites the unrelated kernel memory, causing random kernel crashes. Same issue is possible for extended-lba case also. When user specifies a short unaligned buffer, the kernel makes a copy and uses that for DMA. Detect these situations for sync/uring passthrough, and bail out. Fixes: 456cba386e94 ("nvme: wire-up uring-cmd support for io-passthru on char-device") Cc: stable(a)vger.kernel.org Reported-by: Vincent Fu <vincent.fu(a)samsung.com> Signed-off-by: Kanchan Joshi <joshi.k(a)samsung.com> --- Changes since v2: - Handle extended-lba case: short unaligned buffer IO - Reduce the scope of check to only well-known commands - Do not check early. Move it deeper so that check gets executed less often - Combine two patches into one. Changes since v1: - Revise the check to exclude PRACT=1 case Random crash example: [ 6815.014478] general protection fault, probably for non-canonical address 0x70e3cdbe9133b7a6: 0000 [#1] PREEMPT SMP PTI [ 6815.014505] CPU: 1 PID: 434 Comm: systemd-timesyn Tainted: G OE 6.4.0-rc3+ #5 [ 6815.014516] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.16.2-0-gea1b7a073390-prebuilt.qemu.org 04/01/2014 [ 6815.014522] RIP: 0010:__kmem_cache_alloc_node+0x100/0x440 [ 6815.014551] Code: 48 85 c0 0f 84 fb 02 00 00 41 83 ff ff 74 10 48 8b 00 48 c1 e8 36 41 39 c7 0f 85 e5 02 00 00 41 8b 45 28 49 8b 7d 00 4c 01 e0 <48> 8b 18 48 89 c1 49 33 9d b8 00 00 00 4c 89 e0 48 0f c9 48 31 cb [ 6815.014559] RSP: 0018:ffffb510c0577d18 EFLAGS: 00010216 [ 6815.014569] RAX: 70e3cdbe9133b7a6 RBX: ffff8a9ec1042300 RCX: 0000000000000010 [ 6815.014575] RDX: 00000000048b0001 RSI: 0000000000000dc0 RDI: 0000000000037060 [ 6815.014581] RBP: ffffb510c0577d58 R08: ffffffffb9ffa280 R09: 0000000000000000 [ 6815.014586] R10: ffff8a9ecbcab1f0 R11: 0000000000000000 R12: 70e3cdbe9133b79e [ 6815.014591] R13: ffff8a9ec1042300 R14: 0000000000000dc0 R15: 00000000ffffffff [ 6815.014597] FS: 00007fce590d6940(0000) GS:ffff8a9f3dd00000(0000) knlGS:0000000000000000 [ 6815.014604] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 6815.014609] CR2: 00005579abbb6498 CR3: 000000000d9b0000 CR4: 00000000000006e0 [ 6815.014622] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 6815.014627] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 6815.014632] Call Trace: [ 6815.014650] <TASK> [ 6815.014655] ?
