commit 90cc55f0 upstream. Otherwise we introduce a race condition where userspace can request input before we're ready leading to null pointer dereference such as input: bma150 as /devices/platform/i2c-gpio-2/i2c-5/5-0038/input/input3 Unable to handle kernel NULL pointer dereference at virtual address 00000018 pgd = (ptrval) [00000018] *pgd=55dac831, *pte=00000000, *ppte=00000000 Internal error: Oops: 17 [#1] PREEMPT ARM Modules linked in: bma150 input_polldev [last unloaded: bma150] CPU: 0 PID: 2870 Comm: accelerometer Not tainted 5.0.0-rc3-dirty #46 Hardware name: Samsung S5PC110/S5PV210-based board PC is at input_event+0x8/0x60 LR is at bma150_report_xyz+0x9c/0xe0 [bma150] pc : [<80450f70>] lr : [<7f0a614c>] psr: 800d0013 sp : a4c1fd78 ip : 00000081 fp : 00020000 r10: 00000000 r9 : a5e2944c r8 : a7455000 r7 : 00000016 r6 : 00000101 r5 : a7617940 r4 : 80909048 r3 : fffffff2 r2 : 00000000 r1 : 00000003 r0 : 00000000 Flags: Nzcv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 10c5387d Table: 54e34019 DAC: 00000051 Process accelerometer (pid: 2870, stack limit = 0x(ptrval)) Stackck: (0xa4c1fd78 to 0xa4c20000) fd60: fffffff3 fc813f6c fd80: 40410581 d7530ce3 a5e2817c a7617f00 a5e29404 a5e2817c 00000000 7f008324 fda0: a5e28000 8044f59c a5fdd9d0 a5e2945c a46a4a00 a5e29668 a7455000 80454f10 fdc0: 80909048 a5e29668 a5fdd9d0 a46a4a00 806316d0 00000000 a46a4a00 801df5f0 fde0: 00000000 d7530ce3 a4c1fec0 a46a4a00 00000000 a5fdd9d0 a46a4a08 801df53c fe00: 00000000 801d74bc a4c1fec0 00000000 a4c1ff70 00000000 a7038da8 00000000 fe20: a46a4a00 801e91fc a411bbe0 801f2e88 00000004 00000000 80909048 00000041 fe40: 00000000 00020000 00000000 dead4ead a6a88da0 00000000 ffffe000 806fcae8 fe60: a4c1fec8 00000000 80909048 00000002 a5fdd9d0 a7660110 a411bab0 00000001 fe80: dead4ead ffffffff ffffffff a4c1fe8c a4c1fe8c d7530ce3 20000013 80909048 fea0: 80909048 a4c1ff70 00000001 fffff000 a4c1e000 00000005 00026038 801eabd8 fec0: a7660110 a411bab0 b9394901 00000006 a696201b 76fb3000 00000000 a7039720 fee0: a5fdd9d0 00000101 00000002 00000096 00000000 00000000 00000000 a4c1ff00 ff00: a6b310f4 805cb174 a6b310f4 00000010 00000fe0 00000010 a4c1e000 d7530ce3 ff20: 00000003 a5f41400 a5f41424 00000000 a6962000 00000000 00000003 00000002 ff40: ffffff9c 000a0000 80909048 d7530ce3 a6962000 00000003 80909048 ffffff9c ff60: a6962000 801d890c 00000000 00000000 00020000 a7590000 00000004 00000100 ff80: 00000001 d7530ce3 000288b8 00026320 000288b8 00000005 80101204 a4c1e000 ffa0: 00000005 80101000 000288b8 00026320 000288b8 000a0000 00000000 00000000 ffc0: 000288b8 00026320 000288b8 00000005 7eef3bac 000264e8 00028ad8 00026038 ffe0: 00000005 7eef3300 76f76e91 76f78546 800d0030 000288b8 00000000 00000000 [<80450f70>] (input_event) from [<a5e2817c>] (0xa5e2817c) Code: e1a08148 eaffffa8 e351001f 812fff1e (e590c018) ---[ end trace 1c691ee85f2ff243 ]--- Signed-off-by:

commit dcf6e2e3 upstream. The kblockd workqueue is created with the WQ_MEM_RECLAIM flag set. This generates a rescuer thread for that queue that will trigger when the CPU is under heavy load and collect the uncompleted work. In the case of mmc, this creates the possibility of a deadlock when there are multiple partitions on the device as other blk-mq work is also run on the same queue. For example: - worker 0 claims the mmc host to work on partition 1 - worker 1 attempts to claim the host for partition 2 but has to wait for worker 0 to finish - worker 0 schedules complete_work to release the host - rescuer thread is triggered after time-out and collects the dangling work - rescuer thread attempts to complete the work in order starting with claim host - the task to release host is now blocked by a task to claim it and will never be called The above results in multiple hung tasks that lead to failures to mount partitions. Handling complete_work on a separate workqueue avoids this by keeping the work completion tasks separate from the other blk-mq work. This allows the host to be released without getting blocked by other tasks attempting to claim the host. Signed-off-by:

commit d6f11e7d upstream. The MMC device tree bindings include properties used to signal various signalling speed modes. Until now the sunxi driver was accepting them without any further filtering, while the sunxi device trees were not actually using them. Since some of the H5 boards can not run at higher speed modes stably, we are resorting to declaring the higher speed modes per-board. Regardless, having boards declare modes and blindly following them, even without proper support in the driver, is generally a bad thing. Filter out all unsupported modes from the capabilities mask after the device tree properties have been parsed. Cc: <stable@vger.kernel.org> Signed-off-by:

Following sequence will cause the crash: If we create an 'almost' BTS event with precise_ip and callchains, and it into a BTS event it will crash the perf_prepare_sample() function because precise_ip events are expected to come in with callchain data initialized, but that's not the case for intel_pmu_drain_bts_buffer() caller. Adding a check_period callback to be called before the period is changed via PERF_EVENT_IOC_PERIOD. It will deny the change if the event would become BTS. Plus adding also the limit_period check as well. Reported-by:

commit d0243693 upstream. Commit 83a86fbb ("irqchip/gic: Loudly complain about the use of IRQ_TYPE_NONE") started warning about incorrect dts usage for irqs. ARM GIC only supports active-high interrupts for SPI (Shared Peripheral Interrupts), and the Palmas PMIC by default is active-low. Palmas PMIC allows changing the interrupt polarity using register PALMAS_POLARITY_CTRL_INT_POLARITY, but configuring sys_nirq1 with a pull-down and setting PALMAS_POLARITY_CTRL_INT_POLARITY made the Palmas RTC interrupts stop working. This can be easily tested with kernel tools rtctest.c. Turns out the SoC inverts the sys_nirq pins for GIC as they do not go through a peripheral device but go directly to the MPUSS wakeupgen. I've verified this by muxing the interrupt line temporarily to gpio_wk16 instead of sys_nirq1. with a gpio, the interrupt works fine both active-low and active-high with the SoC internal pull configured and palmas polarity configured. But as sys_nirq1, the interrupt only works when configured ACTIVE_LOW for palmas, and ACTIVE_HIGH for GIC. Note that there was a similar issue earlier with tegra114 and palmas interrupt polarity that got fixed by commit df545d1c ("mfd: palmas: Provide irq flags through DT/platform data"). However, the difference between omap5 and tegra114 is that tegra inverts the palmas interrupt twice, once when entering tegra PMC, and again when exiting tegra PMC to GIC. Let's fix the issue by adding a custom wakeupgen_irq_set_type() for wakeupgen and invert any interrupts with wrong polarity. Let's also warn about any non-sysnirq pins using wrong polarity. Note that we also need to update the dts for the level as IRQ_TYPE_NONE never has irq_set_type() called, and let's add some comments and use proper pin nameing to avoid more confusion later on.

[ Upstream commit 92a8109e ] The code tries to allocate a contiguous buffer with a size supplied by the server (maxBuf). This could fail if memory is fragmented since it results in high order allocations for commonly used server implementations. It is also wasteful since there are probably few locks in the usual case. Limit the buffer to be no larger than a page to avoid memory allocation failures due to fragmentation. Signed-off-by:

As this is early in the boot phase and these allocations really should not fail, any failure here is probably an indication of a more serious issue so it makes little sense to try and rollback the previous allocated resources or try to continue; but rather the probe function is simply exited with -ENOMEM.

[ Upstream commit dcca1662 ] There is an out of bounds array access in nvme_cqe_peding(). When enable irq_thread for nvme interrupt, there is racing between the nvmeq->cq_head updating and reading. nvmeq->cq_head is updated in nvme_update_cq_head(), if nvmeq->cq_head equals nvmeq->q_depth and before its value set to zero, nvme_cqe_pending() uses its value as an array index, the index will be out of bounds.

[ Upstream commit 9a63bd6f ] Initially DP0_SRCCTRL is set to a static value which includes DP0_SRCCTRL_LANES_2 and DP0_SRCCTRL_BW27, even when only 1 lane of 1.62Gbps speed is used. DP1_SRCCTRL is configured to a magic number. This patch changes the configuration as follows: Configure DP0_SRCCTRL by using tc_srcctrl() which provides the correct value. DP1_SRCCTRL needs two bits to be set to the same value as DP0_SRCCTRL: SSCG and BW27. All other bits can be zero. Signed-off-by:

[ Upstream commit 2f661962 ] cpuinfo_cur_freq gets current CPU frequency as detected by hardware while scaling_cur_freq last known CPU frequency. Some platforms may not allow checking the CPU frequency of an offline CPU or the associated resources may have been released via cpufreq_exit when the CPU gets offlined, in which case the policy would have been invalidated already. If we attempt to get current frequency from the hardware, it may result in hang or crash. For example on Juno, I see: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000188 [0000000000000188] pgd=0000000000000000 Internal error: Oops: 96000004 [#1] PREEMPT SMP Modules linked in: CPU: 5 PID: 4202 Comm: cat Not tainted 4.20.0-08251-ga0f2c0318a15-dirty #87 Hardware name: ARM LTD ARM Juno Development Platform/ARM Juno Development Platform pstate: 40000005 (nZcv daif -PAN -UAO) pc : scmi_cpufreq_get_rate+0x34/0xb0 lr : scmi_cpufreq_get_rate+0x34/0xb0 Call trace: scmi_cpufreq_get_rate+0x34/0xb0 __cpufreq_get+0x34/0xc0 show_cpuinfo_cur_freq+0x24/0x78 show+0x40/0x60 sysfs_kf_seq_show+0xc0/0x148 kernfs_seq_show+0x44/0x50 seq_read+0xd4/0x480 kernfs_fop_read+0x15c/0x208 __vfs_read+0x60/0x188 vfs_read+0x94/0x150 ksys_read+0x6c/0xd8 __arm64_sys_read+0x24/0x30 el0_svc_common+0x78/0x100 el0_svc_handler+0x38/0x78 el0_svc+0x8/0xc ---[ end trace 3d1024e58f77f6b2 ]--- So fix the issue by checking if the policy is invalid early in __cpufreq_get before attempting to get the current frequency.
