[ Upstream commit f67169fe ] when configuring act_pedit rules, the number of keys is validated only on addition of a new entry. This is not sufficient to avoid hitting a WARN() in the traffic path: for example, it is possible to replace a valid entry with a new one having 0 extended keys, thus causing splats in dmesg like: pedit BUG: index 42 WARNING: CPU: 2 PID: 4054 at net/sched/act_pedit.c:410 tcf_pedit_act+0xc84/0x1200 [act_pedit] [...] RIP: 0010:tcf_pedit_act+0xc84/0x1200 [act_pedit] Code: 89 fa 48 c1 ea 03 0f b6 04 02 84 c0 74 08 3c 03 0f 8e ac 00 00 00 48 8b 44 24 10 48 c7 c7 a0 c4 e4 c0 8b 70 18 e8 1c 30 95 ea <0f> 0b e9 a0 fa ff ff e8 00 03 f5 ea e9 14 f4 ff ff 48 89 58 40 e9 RSP: 0018:ffff888077c9f320 EFLAGS: 00010286 RAX: 0000000000000000 RBX: 0000000000000000 RCX: ffffffffac2983a2 RDX: 0000000000000001 RSI: 0000000000000008 RDI: ffff888053927bec RBP: dffffc0000000000 R08: ffffed100a726209 R09: ffffed100a726209 R10: 0000000000000001 R11: ffffed100a726208 R12: ffff88804beea780 R13: ffff888079a77400 R14: ffff88804beea780 R15: ffff888027ab2000 FS: 00007fdeec9bd740(0000) GS:ffff888053900000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007ffdb3dfd000 CR3: 000000004adb4006 CR4: 00000000001606e0 Call Trace: tcf_action_exec+0x105/0x3f0 tcf_classify+0xf2/0x410 __dev_queue_xmit+0xcbf/0x2ae0 ip_finish_output2+0x711/0x1fb0 ip_output+0x1bf/0x4b0 ip_send_skb+0x37/0xa0 raw_sendmsg+0x180c/0x2430 sock_sendmsg+0xdb/0x110 __sys_sendto+0x257/0x2b0 __x64_sys_sendto+0xdd/0x1b0 do_syscall_64+0xa5/0x4e0 entry_SYSCALL_64_after_hwframe+0x49/0xbe RIP: 0033:0x7fdeeb72e993 Code: 48 8b 0d e0 74 2c 00 f7 d8 64 89 01 48 83 c8 ff c3 66 0f 1f 44 00 00 83 3d 0d d6 2c 00 00 75 13 49 89 ca b8 2c 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 34 c3 48 83 ec 08 e8 4b cc 00 00 48 89 04 24 RSP: 002b:00007ffdb3de8a18 EFLAGS: 00000246 ORIG_RAX: 000000000000002c RAX: ffffffffffffffda RBX: 000055c81972b700 RCX: 00007fdeeb72e993 RDX: 0000000000000040 RSI: 000055c81972b700 RDI: 0000000000000003 RBP: 00007ffdb3dea130 R08: 000055c819728510 R09: 0000000000000010 R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000040 R13: 000055c81972b6c0 R14: 000055c81972969c R15: 0000000000000080 Fix this moving the check on 'nkeys' earlier in tcf_pedit_init(), so that attempts to install rules having 0 keys are always rejected with -EINVAL.

commit 94bb804e upstream. A number of our uaccess routines ('__arch_clear_user()' and '__arch_copy_{in,from,to}_user()') fail to re-enable PAN if they encounter an unhandled fault whilst accessing userspace. For CPUs implementing both hardware PAN and UAO, this bug has no effect when both extensions are in use by the kernel. For CPUs implementing hardware PAN but not UAO, this means that a kernel using hardware PAN may execute portions of code with PAN inadvertently disabled, opening us up to potential security vulnerabilities that rely on userspace access from within the kernel which would usually be prevented by this mechanism. In other words, parts of the kernel run the same way as they would on a CPU without PAN implemented/emulated at all. For CPUs not implementing hardware PAN and instead relying on software emulation via 'CONFIG_ARM64_SW_TTBR0_PAN=y', the impact is unfortunately much worse. Calling 'schedule()' with software PAN disabled means that the next task will execute in the kernel using the page-table and ASID of the previous process even after 'switch_mm()', since the actual hardware switch is deferred until return to userspace. At this point, or if there is a intermediate call to 'uaccess_enable()', the page-table and ASID of the new process are installed. Sadly, due to the changes introduced by KPTI, this is not an atomic operation and there is a very small window (two instructions) where the CPU is configured with the page-table of the old task and the ASID of the new task; a speculative access in this state is disastrous because it would corrupt the TLB entries for the new task with mappings from the previous address space. As Pavel explains: | I was able to reproduce memory corruption problem on Broadcom's SoC | ARMv8-A like this: | | Enable software perf-events with PERF_SAMPLE_CALLCHAIN so userland's | stack is accessed and copied. | | The test program performed the following on every CPU and forking | many processes: | | unsigned long *map = mmap(NULL, PAGE_SIZE, PROT_READ|PROT_WRITE, | MAP_SHARED | MAP_ANONYMOUS, -1, 0); | map[0] = getpid(); | sched_yield(); | if (map[0] != getpid()) { | fprintf(stderr, "Corruption detected!"); | } | munmap(map, PAGE_SIZE); | | From time to time I was getting map[0] to contain pid for a | different process. Ensure that PAN is re-enabled when returning after an unhandled user fault from our uaccess routines. Cc: Catalin Marinas <catalin.marinas@arm.com> Reviewed-by:

[ Upstream commit 605b3bec ] spidev will make a big fuss if a device tree node binds a device by using "spidev" as the node's compatible property. However, the logic for this isn't looking for "spidev" in the compatible, but rather checking that the device is NOT compatible with spidev's list of devices. This causes a false positive if a device not named "rohm,dh2228fv", etc. binds to spidev, even if a means other than putting "spidev" in the device tree was used. E.g., the sysfs driver_override attribute. Signed-off-by:

[ Upstream commit 51fbf14f ] The only use of KEXEC_BACKUP_SRC_END is as an argument to walk_system_ram_res(): int crash_load_segments(struct kimage *image) { ... walk_system_ram_res(KEXEC_BACKUP_SRC_START, KEXEC_BACKUP_SRC_END, image, determine_backup_region); walk_system_ram_res() expects "start, end" arguments that are inclusive, i.e., the range to be walked includes both the start and end addresses. KEXEC_BACKUP_SRC_END was previously defined as (640 * 1024UL), which is the first address *past* the desired 0-640KB range. Define KEXEC_BACKUP_SRC_END as (640 * 1024UL - 1) so the KEXEC_BACKUP_SRC region is [0-0x9ffff], not [0-0xa0000].

[ Upstream commit 32ae5920 ] Shifting the u8 value[3] by an int can lead to sign-extension overflow. For example, if value[3] is 0xff and the shift is 24 then it is promoted to int and then the top bit is sign-extended so that all upper 32 bits are set. Fix this by casting value[3] to a u32 before the shift. Detected by CoverityScan, CID#1016522 ("Unintended sign extension") Fixes: e0d3bafd ("V4L/DVB (10954): Add cx231xx USB driver") Signed-off-by:

[ Upstream commit 1eb8d738 ] Flushing the workqueue can cause operations to happen which might call gfs2_log_reserve(), or get stuck waiting for locks taken by such operations. gfs2_log_reserve() can io_schedule(). If this happens, it will never wake because the only thing which can wake it is gfs2_logd() which was already stopped. This causes umount of a gfs2 filesystem to wedge permanently if, for example, the umount immediately follows a large delete operation. When this occured, the following stack trace was obtained from the umount command [<ffffffff81087968>] flush_workqueue+0x1c8/0x520 [<ffffffffa0666e29>] gfs2_make_fs_ro+0x69/0x160 [gfs2] [<ffffffffa0667279>] gfs2_put_super+0xa9/0x1c0 [gfs2] [<ffffffff811b7edf>] generic_shutdown_super+0x6f/0x100 [<ffffffff811b7ff7>] kill_block_super+0x27/0x70 [<ffffffffa0656a71>] gfs2_kill_sb+0x71/0x80 [gfs2] [<ffffffff811b792b>] deactivate_locked_super+0x3b/0x70 [<ffffffff811b79b9>] deactivate_super+0x59/0x60 [<ffffffff811d2998>] cleanup_mnt+0x58/0x80 [<ffffffff811d2a12>] __cleanup_mnt+0x12/0x20 [<ffffffff8108c87d>] task_work_run+0x7d/0xa0 [<ffffffff8106d7d9>] exit_to_usermode_loop+0x73/0x98 [<ffffffff81003961>] syscall_return_slowpath+0x41/0x50 [<ffffffff815a594c>] int_ret_from_sys_call+0x25/0x8f [<ffffffffffffffff>] 0xffffffffffffffff Signed-off-by:

[ Upstream commit a26ac6c1 ] In isif_probe(), there is a while loop to get the ISIF base address and linearization table0 and table1 address. In the loop body, the function platform_get_resource() is called to get the resource. If platform_get_resource() returns NULL, the loop is terminated and the execution goes to 'fail_nobase_res'. Suppose the loop is terminated at the first iteration because platform_get_resource() returns NULL and the execution goes to 'fail_nobase_res'. Given that there is another while loop at 'fail_nobase_res' and i equals to 0, one iteration of the second while loop will be executed. However, the second while loop does not check the return value of platform_get_resource(). This can cause a NULL pointer dereference bug if the return value is a NULL pointer. This patch avoids the above issue by adding a check in the second while loop after the call to platform_get_resource(). Signed-off-by:

[ Upstream commit 8c7fd6a3 ] In the past, we needed to program the keys when entering D3. This was since we replaced the image. However, now that there is a single image, this is no longer needed. Note that RSC is sent separately in a new command. This solves issues with newer devices that support PN offload. Since driver re-sent the keys, the PN got zeroed and the receiver dropped the next packets, until PN caught up again. Signed-off-by:

[ Upstream commit 757c968c ] There was a small race when removing the sbshc module where smbus_alarm() had queued acpi_smbus_callback() for deferred execution but it hadn't been run yet, so that when it did run hc had been freed and the module unloaded, resulting in an invalid paging request. A similar race existed when removing the sbs module with regards to acpi_sbs_callback() (which is called from acpi_smbus_callback()). We therefore need to ensure no callbacks are pending or executing before the cleanups are done and the modules are removed. Signed-off-by:
