      usb: cdnsp: Fix a NULL pointer dereference in cdnsp_endpoint_init() · 37307f70
      Zhou Qingyang 提交于
      In cdnsp_endpoint_init(), cdnsp_ring_alloc() is assigned to pep->ring
      and there is a dereference of it in cdnsp_endpoint_init(), which could
      lead to a NULL pointer dereference on failure of cdnsp_ring_alloc().
      
      Fix this bug by adding a check of pep->ring.
      
      This bug was found by a static analyzer. The analysis employs
      differential checking to identify inconsistent security operations
      (e.g., checks or kfrees) between two code paths and confirms that the
      inconsistent operations are not recovered in the current function or
      the callers, so they constitute bugs.
      
      Note that, as a bug found by static analysis, it can be a false
      positive or hard to trigger. Multiple researchers have cross-reviewed
      the bug.
      
      Builds with CONFIG_USB_CDNSP_GADGET=y show no new warnings,
      and our static analyzer no longer warns about this code.

      usb: typec: tcpm: Wait in SNK_DEBOUNCED until disconnect · fbcd13df
      Badhri Jagan Sridharan 提交于
      Stub from the spec:
      "4.5.2.2.4.2 Exiting from AttachWait.SNK State
      A Sink shall transition to Unattached.SNK when the state of both
      the CC1 and CC2 pins is SNK.Open for at least tPDDebounce.
      A DRP shall transition to Unattached.SRC when the state of both
      the CC1 and CC2 pins is SNK.Open for at least tPDDebounce."
      
      This change makes TCPM to wait in SNK_DEBOUNCED state until
      CC1 and CC2 pins is SNK.Open for at least tPDDebounce. Previously,
      TCPM resets the port if vbus is not present in PD_T_PS_SOURCE_ON.
      This causes TCPM to loop continuously when connected to a
      faulty power source that does not present vbus. Waiting in
      SNK_DEBOUNCED also ensures that TCPM is adherant to
      "4.5.2.2.4.2 Exiting from AttachWait.SNK State" requirements.

      xhci: Fix commad ring abort, write all 64 bits to CRCR register. · 09f736aa
      Mathias Nyman 提交于
      Turns out some xHC controllers require all 64 bits in the CRCR register
      to be written to execute a command abort.
      
      The lower 32 bits containing the command abort bit is written first.
      In case the command ring stops before we write the upper 32 bits then
      hardware may use these upper bits to set the commnd ring dequeue pointer.
      
      Solve this by making sure the upper 32 bits contain a valid command
      ring dequeue pointer.
      
      The original patch that only wrote the first 32 to stop the ring went
      to stable, so this fix should go there as well.
