[PATCH] io_uring: prevent io_put_identity() from freeing a static identity

by Tadeusz Struk

Note: this applies to 5.10 stable only. It doesn't trigger on anything above 5.10 as the code there has been substantially reworked. This also doesn't apply to any stable kernel below 5.10 afaict. Syzbot found a bug: KASAN: invalid-free in io_dismantle_req https://syzkaller.appspot.com/bug?id=123d9a852fc88ba573ffcb2dbcf4f9576c3b05… The test submits bunch of io_uring writes and exits, which then triggers uring_task_cancel() and io_put_identity(), which in some corner cases, tries to free a static identity. This causes a panic as shown in the trace below: BUG: KASAN: double-free or invalid-free in kfree+0xd5/0x310 CPU: 0 PID: 4618 Comm: repro Not tainted 5.10.76-05281-g4944ec82ebb9-dirty #17 Call Trace: dump_stack_lvl+0x1b2/0x21b print_address_description+0x8d/0x3b0 kasan_report_invalid_free+0x58/0x130 ____kasan_slab_free+0x14b/0x170 __kasan_slab_free+0x11/0x20 slab_free_freelist_hook+0xcc/0x1a0 kfree+0xd5/0x310 io_dismantle_req+0x9b0/0xd90 io_do_iopoll+0x13a4/0x23e0 io_iopoll_try_reap_events+0x116/0x290 io_uring_cancel_task_requests+0x197d/0x1ee0 io_uring_flush+0x170/0x6d0 filp_close+0xb0/0x150 put_files_struct+0x1d4/0x350 exit_files+0x80/0xa0 do_exit+0x6d9/0x2390 do_group_exit+0x16a/0x2d0 get_signal+0x133e/0x1f80 arch_do_signal+0x7b/0x610 exit_to_user_mode_prepare+0xaa/0xe0 syscall_exit_to_user_mode+0x24/0x40 do_syscall_64+0x3d/0x70 entry_SYSCALL_64_after_hwframe+0x44/0xa9 Allocated by task 4611: ____kasan_kmalloc+0xcd/0x100 __kasan_kmalloc+0x9/0x10 kmem_cache_alloc_trace+0x208/0x390 io_uring_alloc_task_context+0x57/0x550 io_uring_add_task_file+0x1f7/0x290 io_uring_create+0x2195/0x3490 __x64_sys_io_uring_setup+0x1bf/0x280 do_syscall_64+0x31/0x70 entry_SYSCALL_64_after_hwframe+0x44/0xa9 The buggy address belongs to the object at ffff88810732b500 which belongs to the cache kmalloc-192 of size 192 The buggy address is located 88 bytes inside of 192-byte region [ffff88810732b500, ffff88810732b5c0) Kernel panic - not syncing: panic_on_warn set ...

[PATCH stable] drm/vc4: hdmi: Fix improper merge conflict with CEC

by Maxime Ripard

Commit 20b0dfa86bef0e80b41b0e5ac38b92f23b6f27f9 upstream. The original commit depended on a rework commit (724fc856c09e ("drm/vc4: hdmi: Split the CEC disable / enable functions in two")) that (rightfully) didn't reach stable. However, probably because the context changed, when the patch was applied to stable the pm_runtime_put called got moved to the end of the vc4_hdmi_cec_adap_enable function (that would have become vc4_hdmi_cec_disable with the rework) to vc4_hdmi_cec_init. This means that at probe time, we now drop our reference to the clocks and power domains and thus end up with a CPU hang when the CPU tries to access registers. The call to pm_runtime_resume_and_get() is also problematic since the .adap_enable CEC hook is called both to enable and to disable the controller. That means that we'll now call pm_runtime_resume_and_get() at disable time as well, messing with the reference counting. The behaviour we should have though would be to have pm_runtime_resume_and_get() called when the CEC controller is enabled, and pm_runtime_put when it's disabled. We need to move things around a bit to behave that way, but it aligns stable with upstream.

This list is only accessed from current cpu and not protected by any locks. But from the commit ef54c1a476ae ("perf: Rework perf_event_exit_event()"), it's possible to access (actually modify) the list from another cpu. In the perf_remove_from_context(), it can remove an event from the context without an IPI when the context is not active. This is not safe with cgroup events which can have some active events in the context even if ctx->is_active is 0 at the moment. The target cpu might be in the middle of list iteration at the same time. If the event is enabled when it's about to be closed, it might call perf_cgroup_event_disable() and list_del() with the cgrp_cpuctx_list on a different cpu. This resulted in a crash due to an invalid list pointer access during the cgroup list traversal on the cpu which the event belongs to. Let's fallback to IPI to access the cgrp_cpuctx_list from that cpu. Similarly, perf_install_in_context() should use IPI for the cgroup events too.

[PATCH v2] PCI: imx6: Allow to probe when dw_pcie_wait_for_link() fails

by Fabio Estevam

The intention of commit 886a9c134755 ("PCI: dwc: Move link handling into common code") was to standardize the behavior of link down as explained in its commit log: "The behavior for a link down was inconsistent as some drivers would fail probe in that case while others succeed. Let's standardize this to succeed as there are usecases where devices (and the link) appear later even without hotplug. For example, a reconfigured FPGA device." The pci-imx6 still fails to probe when the link is not present, which causes the following warning: imx6q-pcie 8ffc000.pcie: Phy link never came up imx6q-pcie: probe of 8ffc000.pcie failed with error -110 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 30 at drivers/regulator/core.c:2257 _regulator_put.part.0+0x1b8/0x1dc Modules linked in: CPU: 0 PID: 30 Comm: kworker/u2:2 Not tainted 5.15.0-next-20211103 #1 Hardware name: Freescale i.MX6 SoloX (Device Tree) Workqueue: events_unbound async_run_entry_fn [<c0111730>] (unwind_backtrace) from [<c010bb74>] (show_stack+0x10/0x14) [<c010bb74>] (show_stack) from [<c0f90290>] (dump_stack_lvl+0x58/0x70) [<c0f90290>] (dump_stack_lvl) from [<c012631c>] (__warn+0xd4/0x154) [<c012631c>] (__warn) from [<c0f87b00>] (warn_slowpath_fmt+0x74/0xa8) [<c0f87b00>] (warn_slowpath_fmt) from [<c076b4bc>] (_regulator_put.part.0+0x1b8/0x1dc) [<c076b4bc>] (_regulator_put.part.0) from [<c076b574>] (regulator_put+0x2c/0x3c) [<c076b574>] (regulator_put) from [<c08c3740>] (release_nodes+0x50/0x178) Fix this problem by ignoring the dw_pcie_wait_for_link() error like it is done on the other dwc drivers.

[PATCH v3] sched/fair: Fix fault in reweight_entity

by Tadeusz Struk

Syzbot found a GPF in reweight_entity. This has been bisected to commit 4ef0c5c6b5ba ("kernel/sched: Fix sched_fork() access an invalid sched_task_group") There is a race between sched_post_fork() and setpriority(PRIO_PGRP) within a thread group that causes a null-ptr-deref in reweight_entity() in CFS. The scenario is that the main process spawns number of new threads, which then call setpriority(PRIO_PGRP, 0, -20), wait, and exit. For each of the new threads the copy_process() gets invoked, which adds the new task_struct and calls sched_post_fork() for it. In the above scenario there is a possibility that setpriority(PRIO_PGRP) and set_one_prio() will be called for a thread in the group that is just being created by copy_process(), and for which the sched_post_fork() has not been executed yet. This will trigger a null pointer dereference in reweight_entity(), as it will try to access the run queue pointer, which hasn't been set. This results it a crash as shown below: KASAN: null-ptr-deref in range [0x00000000000000a0-0x00000000000000a7] CPU: 0 PID: 2392 Comm: reduced_repro Not tainted 5.16.0-11201-gb42c5a161ea3 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1.fc35 04/01/2014 RIP: 0010:reweight_entity+0x15d/0x440 RSP: 0018:ffffc900035dfcf8 EFLAGS: 00010006 Call Trace: <TASK> reweight_task+0xde/0x1c0 set_load_weight+0x21c/0x2b0 set_user_nice.part.0+0x2d1/0x519 set_user_nice.cold+0x8/0xd set_one_prio+0x24f/0x263 __do_sys_setpriority+0x2d3/0x640 __x64_sys_setpriority+0x84/0x8b do_syscall_64+0x35/0xb0 entry_SYSCALL_64_after_hwframe+0x44/0xae </TASK> ---[ end trace 9dc80a9d378ed00a ]--- Before the mentioned change the cfs_rq pointer for the task has been set in sched_fork(), which is called much earlier in copy_process(), before the new task is added to the thread_group. Now it is done in the sched_post_fork(), which is called after that. To fix the issue the update_load condition passed to set_load_weight() in set_user_nice() and __sched_setscheduler() has been changed from always true to true if the task->state != TASK_NEW.
