      xen/acpi: allow xen-acpi-processor driver to load on Xen 4.7 · 6f2d9d99

      As of Xen 4.7 PV CPUID doesn't expose either of CPUID[1].ECX[7] and
      CPUID[0x80000007].EDX[7] anymore, causing the driver to fail to load on
      both Intel and AMD systems. Doing any kind of hardware capability
      checks in the driver as a prerequisite was wrong anyway: With the
      hypervisor being in charge, all such checking should be done by it. If
      ACPI data gets uploaded despite some missing capability, the hypervisor
      is free to ignore part or all of that data.
      
      Ditch the entire check_prereq() function, and do the only valid check
      (xen_initial_domain()) in the caller in its place.

      xenbus: don't bail early from xenbus_dev_request_and_reply() · 7469be95
      Jan Beulich authored
      xenbus_dev_request_and_reply() needs to track whether a transaction is
      open.  For XS_TRANSACTION_START messages it calls transaction_start()
      and for XS_TRANSACTION_END messages it calls transaction_end().
      
      If sending an XS_TRANSACTION_START message fails or responds with an
      an error, the transaction is not open and transaction_end() must be
      called.
      
      If sending an XS_TRANSACTION_END message fails, the transaction is
      still open, but if an error response is returned the transaction is
      closed.
      
      Commit 027bd7e8
      
       ("xen/xenbus: Avoid synchronous wait on XenBus
      stalling shutdown/restart") introduced a regression where failed
      XS_TRANSACTION_START messages were leaving the transaction open.  This
      can cause problems with suspend (and migration) as all transactions
      must be closed before suspending.
      
      It appears that the problematic change was added accidentally, so just
      remove it.

      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>

      It fixed a local root exploit but also introduced a dependency on
      the lower file system implementing an mmap operation just to open a file,
      which is a bit of a heavy hammer.  The right fix is to have mmap depend
      on the existence of the mmap handler instead.

      arm64: kernel: Save and restore UAO and addr_limit on exception entry · e19a6ee2
      James Morse authored
      
      
      If we take an exception while at EL1, the exception handler inherits
      the original context's addr_limit and PSTATE.UAO values. To be consistent
      always reset addr_limit and PSTATE.UAO on (re-)entry to EL1. This
      prevents accidental re-use of the original context's addr_limit.
      
      Based on a similar patch for arm from Russell King.

      perf/core: Fix pmu::filter_match for SW-led groups · 2c81a647
      Mark Rutland authored
      The following commit:
      
        66eb579e
      
       ("perf: allow for PMU-specific event filtering")
      
      added the pmu::filter_match() callback. This was intended to
      avoid HW constraints on events from resulting in extremely
      pessimistic scheduling.
      
      However, pmu::filter_match() is only called for the leader of each event
      group. When the leader is a SW event, we do not filter the groups, and
      may fail at pmu::add() time, and when this happens we'll give up on
      scheduling any event groups later in the list until they are rotated
      ahead of the failing group.
      
      This can result in extremely sub-optimal event scheduling behaviour,
      e.g. if running the following on a big.LITTLE platform:
      
      $ taskset -c 0 ./perf stat \
       -e 'a57{context-switches,armv8_cortex_a57/config=0x11/}' \
       -e 'a53{context-switches,armv8_cortex_a53/config=0x11/}' \
       ls
      
           <not counted>      context-switches                                              (0.00%)
           <not counted>      armv8_cortex_a57/config=0x11/                                 (0.00%)
                      24      context-switches                                              (37.36%)
                57589154      armv8_cortex_a53/config=0x11/                                 (37.36%)
      
      Here the 'a53' event group was always eligible to be scheduled, but
      the 'a57' group never eligible to be scheduled, as the task was always
      affine to a Cortex-A53 CPU. The SW (group leader) event in the 'a57'
      group was eligible, but the HW event failed at pmu::add() time,
      resulting in ctx_flexible_sched_in giving up on scheduling further
      groups with HW events.
      
      One way of avoiding this is to check pmu::filter_match() on siblings
      as well as the group leader. If any of these fail their
      pmu::filter_match() call, we must skip the entire group before
      attempting to add any events.

      init/Kconfig: keep Expert users menu together · 076501ff
      Randy Dunlap authored
      The "expert" menu was broken (split) such that all entries in it after
      KALLSYMS were displayed in the "General setup" area instead of in the
      "Expert users" area.  Fix this by adding one kconfig dependency.
      
      Yes, the Expert users menu is fragile.  Problems like this have happened
      several times in the past.  I will attempt to isolate the Expert users
      menu if there is interest in that.
