[PATCH v2 3/3] HID: logitech-hidpp: do all FF cleanup in hidpp_ff_destroy()

by Andrey Smirnov

All of the FF-related resources belong to corresponding FF device, so they should be freed as a part of hidpp_ff_destroy() to avoid potential race condidions.

[PATCH v2 1/3] HID: logitech-hidpp: split g920_get_config()

by Andrey Smirnov

Original version of g920_get_config() contained two kind of actions: 1. Device specific communication to query/set some parameters which requires active communication channel with the device, or, put in other way, for the call to be sandwiched between hid_device_io_start() and hid_device_io_stop(). 2. Input subsystem specific FF controller initialization which, in order to access a valid 'struct hid_input' via 'hid->inputs.next', requires claimed hidinput which means be executed after the call to hid_hw_start() with connect_mask containing HID_CONNECT_HIDINPUT. Location of g920_get_config() can only fulfill requirements for #1 and not #2, which might result in following backtrace: [ 88.312258] logitech-hidpp-device 0003:046D:C262.0005: HID++ 4.2 device connected.

[BACKPORT v4.19] PCI: vmd: Fix config addressing when using bus offsets

by Sushma Kalakota

From: Jon Derrick <jonathan.derrick(a)intel.com> commit e3dffa4f6c3612dea337c9c59191bd418afc941b upstream This is a backport due to feature dependencies preventing the upstream patch from applying cleanly. VMD maps child device config spaces to the VMD Config BAR linearly regardless of the starting bus offset. Because of this, the config address decode must ignore starting bus offsets when mapping the BDF to the config space address.

[PATCH v2 bpf-next] bpf/stackmap: fix deadlock with rq_lock in bpf_get_stack()

by Song Liu

bpf stackmap with build-id lookup (BPF_F_STACK_BUILD_ID) can trigger A-A deadlock on rq_lock(): rcu: INFO: rcu_sched detected stalls on CPUs/tasks: [...] Call Trace: try_to_wake_up+0x1ad/0x590 wake_up_q+0x54/0x80 rwsem_wake+0x8a/0xb0 bpf_get_stack+0x13c/0x150 bpf_prog_fbdaf42eded9fe46_on_event+0x5e3/0x1000 bpf_overflow_handler+0x60/0x100 __perf_event_overflow+0x4f/0xf0 perf_swevent_overflow+0x99/0xc0 ___perf_sw_event+0xe7/0x120 __schedule+0x47d/0x620 schedule+0x29/0x90 futex_wait_queue_me+0xb9/0x110 futex_wait+0x139/0x230 do_futex+0x2ac/0xa50 __x64_sys_futex+0x13c/0x180 do_syscall_64+0x42/0x100 entry_SYSCALL_64_after_hwframe+0x44/0xa9 This can be reproduced by: 1. Start a multi-thread program that does parallel mmap() and malloc(); 2. taskset the program to 2 CPUs; 3. Attach bpf program to trace_sched_switch and gather stackmap with build-id, e.g. with trace.py from bcc tools: trace.py -U -p <pid> -s <some-bin,some-lib> t:sched:sched_switch A sample reproducer is attached at the end. This could also trigger deadlock with other locks that are nested with rq_lock. Fix this by checking whether irqs are disabled. Since rq_lock and all other nested locks are irq safe, it is safe to do up_read() when irqs are not disable. If the irqs are disabled, postpone up_read() in irq_work.
