      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

      perf timechart: Adjust perf timechart to the new power events · 20c457b8
      Thomas Renninger authored
      builtin-timechart must only pass -e power:xy events if they are supported by
      the running kernel, otherwise try to fetch the old power:power{start,end}
      events.
      
      For this I added the tiny helper function:
      
         int is_valid_tracepoint(const char *event_string)
      
      to parse-events.[hc], which could be more generic as an interface and support
      hardware/software/... events, not only tracepoints, but someone else could
      extend that if needed...

      perf: Clean up power events by introducing new, more generic ones · 25e41933
      Thomas Renninger authored
      Add these new power trace events:
      
       power:cpu_idle
       power:cpu_frequency
       power:machine_suspend
      
      The old C-state/idle accounting events:
        power:power_start
        power:power_end
      
      Have now a replacement (but we are still keeping the old
      tracepoints for compatibility):
      
        power:cpu_idle
      
      and
        power:power_frequency
      
      is replaced with:
        power:cpu_frequency
      
      power:machine_suspend is newly introduced.
      
      Jean Pihet has a patch integrated into the generic layer
      (kernel/power/suspend.c) which will make use of it.
      
      the type= field got removed from both, it was never
      used and the type is differed by the event type itself.
      
      perf timechart userspace tool gets adjusted in a separate patch.

      perf test: Add test for counting open syscalls · d854861c
      Arnaldo Carvalho de Melo authored
      To test the use of the perf_evsel class on something other than
      the tools from where we refactored code to create it.
      
      It calls open() N times and then checks if the event created to
      monitor it returns N events.
      
      [acme@felicio linux]$ perf test
       1: vmlinux symtab matches kallsyms: Ok
       2: detect open syscall event: Ok
      [acme@felicio linux]$
      
      It does.

      perf evsel: Auto allocate resources needed for some methods · 4eed11d5
      Arnaldo Carvalho de Melo authored
      While writing the first user of the routines created from the ad-hoc
      routines in the existing builtins I noticed that the resulting set of
      calls was too long, reduce it by doing some best effort allocations.
      
      Tools that need to operate on multiple threads and cpus should pre-allocate
      enough resources by explicitely calling the perf_evsel__alloc_{fd,counters}
      methods.

      Abstracting away the loops needed to create the various event fd handlers.
      
      The users have to pass a confiruged perf->evsel.attr field, which is already

      Comes out of the ad-hoc routines in builtin-stat, that now uses it.

      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

      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.

      bridge: fix br_multicast_ipv6_rcv for paged skbs · 9d89081d
      Tomas Winkler authored
      use pskb_may_pull to access ipv6 header correctly for paged skbs
      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
      
      this fixes bug https://bugzilla.kernel.org/show_bug.cgi?id=25202

      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.

      Out of ad-hoc code and global arrays with hard coded sizes.
      
      This is the first step on having a library that will be first
      used on regression tests in the 'perf test' tool.
