      firewire: nosy: Fix a use-after-free bug in nosy_ioctl() · 829933ef
      Zheyu Ma authored
      For each device, the nosy driver allocates a pcilynx structure.
      A use-after-free might happen in the following scenario:
       1. Open nosy device for the first time and call ioctl with command
          NOSY_IOC_START, then a new client A will be malloced and added to
          doubly linked list.
       2. Open nosy device for the second time and call ioctl with command
          NOSY_IOC_START, then a new client B will be malloced and added to
          doubly linked list.
       3. Call ioctl with command NOSY_IOC_START for client A, then client A
          will be readded to the doubly linked list. Now the doubly linked
          list is messed up.
       4. Close the first nosy device and nosy_release will be called. In
          nosy_release, client A will be unlinked and freed.
       5. Close the second nosy device, and client A will be referenced,
          resulting in UAF.
      The root cause of this bug is that the element in the doubly linked list
      is reentered into the list.
      Fix this bug by adding a check before inserting a client.  If a client
      is already in the linked list, don't insert it.
      The following KASAN report reveals it:
         BUG: KASAN: use-after-free in nosy_release+0x1ea/0x210

      workqueue/watchdog: Make unbound workqueues aware of touch_softlockup_watchdog() · 89e28ce6
      Wang Qing authored
      There are two workqueue-specific watchdog timestamps:
          + @wq_watchdog_touched_cpu (per-CPU) updated by
          + @wq_watchdog_touched (global) updated by
      watchdog_timer_fn() checks only the global @wq_watchdog_touched for
      unbound workqueues. As a result, unbound workqueues are not aware
      of touch_softlockup_watchdog(). The watchdog might report a stall
      even when the unbound workqueues are blocked by a known slow code.
      touch_softlockup_watchdog() must touch also the global @wq_watchdog_touched
      The global timestamp can no longer be used for bound workqueues because
      it is now updated from all CPUs. Instead, bound workqueues have to check
      only @wq_watchdog_touched_cpu and these timestamps have to be updated for
      all CPUs in touch_all_softlockup_watchdogs().
      The change might cause the opposite problem. An unbound workqueue
      might get blocked on CPU A because of a real softlockup. The workqueue
      watchdog would miss it when the timestamp got touched on CPU B.
      It is acceptable because softlockups are detected by softlockup
      watchdog. The workqueue watchdog is there to detect stalls where
      a work never finishes, for example, because of dependencies of works
      queued into the same workqueue.
      - Modify the commit message clearly according to Petr's suggestion.

      ARM: dts: turris-omnia: configure LED[2]/INTn pin as interrupt pin · a26c56ae
      Marek Behún authored
      Use the `marvell,reg-init` DT property to configure the LED[2]/INTn pin
      of the Marvell 88E1514 ethernet PHY on Turris Omnia into interrupt mode.
      Without this the pin is by default in LED[2] mode, and the Marvell PHY
      driver configures LED[2] into "On - Link, Blink - Activity" mode.
      This fixes the issue where the pca9538 GPIO/interrupt controller (which
      can't mask interrupts in HW) received too many interrupts and after a
      time started ignoring the interrupt with error message:
        IRQ 71: nobody cared
      There is a work in progress to have the Marvell PHY driver support
      parsing PHY LED nodes from OF and registering the LEDs as Linux LED
      class devices. Once this is done the PHY driver can also automatically
      set the pin into INTn mode if it does not find LED[2] in OF.
      Until then, though, we fix this via `marvell,reg-init` DT property.
