      apparmor: fix oops, validate buffer size in apparmor_setprocattr() · 30a46a46
      Vegard Nossum authored
      When proc_pid_attr_write() was changed to use memdup_user apparmor's
      (interface violating) assumption that the setprocattr buffer was always
      a single page was violated.
      
      The size test is not strictly speaking needed as proc_pid_attr_write()
      will reject anything larger, but for the sake of robustness we can keep
      it in.
      
      SMACK and SELinux look safe to me, but somebody else should probably
      have a look just in case.
      
      Based on original patch from Vegard Nossum <vegard.nossum@oracle.com>
      modified for the case that apparmor provides null termination.

      irqchip/mips-gic: Match IPI IRQ domain by bus token only · 547aefc4
      Paul Burton authored
      Commit fbde2d7d ("MIPS: Add generic SMP IPI support") introduced
      code which calls irq_find_matching_host with a NULL node parameter in
      order to discover IPI IRQ domains which are not associated with the DT
      root node's interrupt parent. This suggests that implementations of IPI
      IRQ domains should effectively ignore the node parameter if it is NULL
      and search purely based upon the bus token. Commit 2af70a96
      ("irqchip/mips-gic: Add a IPI hierarchy domain") did not do this when
      implementing the GIC IPI IRQ domain, and on MIPS Boston boards this
      leads to no IPI domain being discovered and a NULL pointer dereference
      when attempting to send an IPI:

      irqchip/mips-gic: Map to VPs using HW VPNum · 99ec8a36
      Paul Burton authored
      When mapping an interrupt to a VP(E) we must use the identifier for the
      VP that the hardware expects, and this does not always match up with the
      Linux CPU number. Commit d46812bb ("irqchip: mips-gic: Use HW IDs
      for VPE_OTHER_ADDR") corrected this for the cases that existed at the
      time it was written, but commit 2af70a96 ("irqchip/mips-gic: Add a
      IPI hierarchy domain") added another case before the former patch was
      merged. This leads to incorrectly using Linux CPU numbers when mapping
      interrupts to VPs, which breaks on certain systems such as those with
      multi-core I6400 CPUs. Fix by adding the appropriate call to
      mips_cm_vp_id() to retrieve the expected VP identifier.
