      ipv4/route.c: respect prefsrc for local routes · 9fc3bbb4
      Joel Sing authored
      
      The preferred source address is currently ignored for local routes,
      which results in all local connections having a src address that is the
      same as the local dst address. Fix this by respecting the preferred source
      address when it is provided for local routes.
      
      This bug can be demonstrated as follows:
      
       # ifconfig dummy0 192.168.0.1
       # ip route show table local | grep local.*dummy0
       local 192.168.0.1 dev dummy0  proto kernel  scope host  src 192.168.0.1
       # ip route change table local local 192.168.0.1 dev dummy0 \
           proto kernel scope host src 127.0.0.1
       # ip route show table local | grep local.*dummy0
       local 192.168.0.1 dev dummy0  proto kernel  scope host  src 127.0.0.1
      
      We now establish a local connection and verify the source IP
      address selection:
      
       # nc -l 192.168.0.1 3128 &
       # nc 192.168.0.1 3128 &
       # netstat -ant | grep 192.168.0.1:3128.*EST
       tcp        0      0 192.168.0.1:3128        192.168.0.1:33228 ESTABLISHED
       tcp        0      0 192.168.0.1:33228       192.168.0.1:3128  ESTABLISHED

      ima: fix add LSM rule bug · 867c2026
      Mimi Zohar authored
      
      If security_filter_rule_init() doesn't return a rule, then not everything
      is as fine as the return code implies.
      
      This bug only occurs when the LSM (eg. SELinux) is disabled at runtime.
      
      Adding an empty LSM rule causes ima_match_rules() to always succeed,
      ignoring any remaining rules.
      
       default IMA TCB policy:
        # PROC_SUPER_MAGIC
        dont_measure fsmagic=0x9fa0
        # SYSFS_MAGIC
        dont_measure fsmagic=0x62656572
        # DEBUGFS_MAGIC
        dont_measure fsmagic=0x64626720
        # TMPFS_MAGIC
        dont_measure fsmagic=0x01021994
        # SECURITYFS_MAGIC
        dont_measure fsmagic=0x73636673
      
        < LSM specific rule >
        dont_measure obj_type=var_log_t
      
        measure func=BPRM_CHECK
        measure func=FILE_MMAP mask=MAY_EXEC
        measure func=FILE_CHECK mask=MAY_READ uid=0
      
      Thus without the patch, with the boot parameters 'tcb selinux=0', adding
      the above 'dont_measure obj_type=var_log_t' rule to the default IMA TCB
      measurement policy, would result in nothing being measured.  The patch
      prevents the default TCB policy from being replaced.

      bridge: stp: ensure mac header is set · e6f26129
      Florian Westphal authored
      commit bf9ae538
      (llc: use dev_hard_header) removed the
      skb_reset_mac_header call from llc_mac_hdr_init.
      
      This seems fine itself, but br_send_bpdu() invokes ebtables LOCAL_OUT.
      
      We oops in ebt_basic_match() because it assumes eth_hdr(skb) returns
      a meaningful result.

      The function can't be __init itself (being called from some sysfs
      handler), and hence none of the functions it calls can be either.

      It was omitted in the bridge code leading to crash in blind
      __skb_pull
      
      since the skb is cloned undonditionally we also simplify the
      the exit path

      atl1: fix oops when changing tx/rx ring params · 2f32c867
      J. K. Cliburn authored
      
      Commit 3f5a2a71 zeroes out the statistics
      message block (SMB) and coalescing message block (CMB) when adapter ring
      resources are freed.  This is desirable behavior, but, as a side effect,
      the commit leads to an oops when atl1_set_ringparam() attempts to alter
      the number of rx or tx elements in the ring buffer (by using ethtool
      -G, for example).  We don't want SMB or CMB to change during this
      operation.
      
      Modify atl1_set_ringparam() to preserve SMB and CMB when changing ring
      parameters.

      ARM: pxa: fix page table corruption on resume · 24c78557
      Aric D. Blumer authored
      
      Before this patch, the following error would sometimes occur after a
      resume on pxa3xx:
      
          /path/to/mm/memory.c:144: bad pmd 8040542e.
      
      The problem was that a temporary page table mapping was being improperly
      restored.
      
      The PXA3xx resume code creates a temporary mapping of resume_turn_on_mmu
      to avoid a prefetch abort.  The pxa3xx_resume_after_mmu code requires
      that the r1 register holding the address of this mapping not be
      modified, however, resume_turn_on_mmu does modify it. It is mostly
      correct in that r1 receives the base table address, but it may also
      get other bits in 13:0.  This results in pxa3xx_resume_after_mmu
      restoring the original mapping to the wrong place, corrupting memory
      and leaving the temporary mapping in place.

      perf: Fix callchain hit bad cast on ascii display · d425de54
      Frederic Weisbecker authored
      
      ipchain__fprintf_graph() casts the number of hits in a branch as an
      int, which means we lose its highests bits.
      
      This results in meaningless number of callchain hits in perf.data
      that have a high number of hits recorded, typically those that have
      callchain branches hits appearing more than INT_MAX. This happens
      easily as those are pondered by the event period.

      Disable preemption in init_ibs(). The function only checks the
      ibs capabilities and sets up pci devices (if necessary). It runs
      only on one cpu but operates with the local APIC and some MSRs,
      thus it is better to disable preemption.

      This patch fixes a regression that crept into 2.6.36.
      
      The volume control scale in the cx25840 driver has an unusual mapping
      from register values to v4l2 volume control values.  Enforce the mapping
      limits, so that the default volume control setting does not fall out of
      bounds to prevent the cx25840 module device probe from failing.

      does not make it clear that this is a fatal error for the

      Fix that.
