      objtool: Fix "noreturn" detection for recursive sibling calls · 0afd0d9e
      Josh Poimboeuf authored
      Objtool has some crude logic for detecting static "noreturn" functions
      (aka "dead ends").  This is necessary for being able to correctly follow
      GCC code flow when such functions are called.
      
      It's remotely possible for two functions to call each other via sibling
      calls.  If they don't have RET instructions, objtool's noreturn
      detection logic goes into a recursive loop:
      
        drivers/char/ipmi/ipmi_ssif.o: warning: objtool: return_hosed_msg()+0x0: infinite recursion (objtool bug!)
        drivers/char/ipmi/ipmi_ssif.o: warning: objtool: deliver_recv_msg()+0x0: infinite recursion (objtool bug!)
      
      Instead of reporting an error in this case, consider the functions to be
      non-dead-ends.

      objtool, kprobes/x86: Sync the latest <asm/insn.h> header with tools/objtool/arch/x86/include/asm/insn.h
      
      The following commit:
      
        ee6a7354: kprobes/x86: Prohibit probing on exception masking instructions
      
      Modified <asm/insn.h>, adding the insn_masking_exception() function.
      
      Sync the tooling version of the header to it, to fix this warning:
      
        Warning: synced file at 'tools/objtool/arch/x86/include/asm/insn.h' differs from latest kernel version at 'arch/x86/include/asm/insn.h'

      net sched actions: fix refcnt leak in skbmod · a52956df
      Roman Mashak authored
      When application fails to pass flags in netlink TLV when replacing
      existing skbmod action, the kernel will leak refcnt:
      
      $ tc actions get action skbmod index 1
      total acts 0
      
              action order 0: skbmod pipe set smac 00:11:22:33:44:55
               index 1 ref 1 bind 0
      
      For example, at this point a buggy application replaces the action with
      index 1 with new smac 00:aa:22:33:44:55, it fails because of zero flags,
      however refcnt gets bumped:
      
      $ tc actions get actions skbmod index 1
      total acts 0
      
              action order 0: skbmod pipe set smac 00:11:22:33:44:55
               index 1 ref 2 bind 0
      $
      
      Tha patch fixes this by calling tcf_idr_release() on existing actions.

      Intel Wired LAN Driver Updates 2018-05-11
      
      This series contains fixes to the ice, ixgbe and ixgbevf drivers.
      
      Jeff Shaw provides a fix to ensure rq_last_status gets set, whether or
      not the hardware responds with an error in the ice driver.
      
      Emil adds a check for unsupported module during the reset routine for
      ixgbe.
      
      Luc Van Oostenryck fixes ixgbevf_xmit_frame() where it was not using the

      The caller calls action's ->init() and passes pointer to "struct tc_action *a",
      which later may be initialized to point at the existing action, otherwise
      "struct tc_action *a" is still invalid, and therefore dereferencing it is an
      error as happens in tcf_idr_release, where refcnt is decremented.
      
      So in case of missing flags tcf_idr_release must be called only for
      existing actions.

      nvme: add quirk to force medium priority for SQ creation · 9abd68ef
      Jens Axboe authored
      Some P3100 drives have a bug where they think WRRU (weighted round robin)
      is always enabled, even though the host doesn't set it. Since they think
      it's enabled, they also look at the submission queue creation priority. We
      used to set that to MEDIUM by default, but that was removed in commit
      81c1cd98. This causes various issues on that drive. Add a quirk to
      still set MEDIUM priority for that controller.

      ixgbe: fix memory leak on ipsec allocation · c89ebb96
      Colin Ian King authored
      The error clean up path kfree's adapter->ipsec and should be
      instead kfree'ing ipsec. Fix this.  Also, the err1 error exit path
      does not need to kfree ipsec because this failure path was for
      the failed allocation of ipsec.

      ixgbevf: fix ixgbevf_xmit_frame()'s return type · cf12aab6
      Luc Van Oostenryck authored
      The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
      which is a typedef for an enum type, but the implementation in this
      driver returns an 'int'.
      
      Fix this by returning 'netdev_tx_t' in this driver too.
