      selftests: openvswitch: Support implicit ipv6 arguments. · 51458e10
      Aaron Conole authored
      The current iteration of IPv6 support requires explicit fields to be set
      in addition to not properly support the actual IPv6 addresses properly.
      With this change, make it so that the ipv6() bare option is usable to
      create wildcarded flows to match broad swaths of ipv6 traffic.

      selftests: openvswitch: Add support for tunnel() key. · fefe3b7d
      Aaron Conole authored
      This will be used when setting details about the tunnel to use as
      transport.  There is a difference between the ODP format between tunnel():
      the 'key' flag is not actually a flag field, so we don't support it in the
      same way that the vswitchd userspace supports displaying it.

      selftests: openvswitch: Add set() and set_masked() support. · a4126f90
      Aaron Conole authored
      These will be used in upcoming commits to set specific attributes for
      interacting with tunnels.  Since set() will use the key parsing routine, we
      also make sure to prepend it with an open paren, for the action parsing to
      properly understand it.

      selftests: openvswitch: Refactor actions parsing. · 37de65a7
      Aaron Conole authored
      Until recently, the ovs-dpctl utility was used with a limited actions set
      and didn't need to have support for multiple similar actions.  However,
      when adding support for tunnels, it will be important to support multiple
      set() actions in a single flow.  When printing these actions, the existing
      code will be unable to print all of the sets - it will only print the
      first.
      
      Refactor this code to be easier to read and support multiple actions of the
      same type in an action list.

      selftests: openvswitch: Support explicit tunnel port creation. · f94ecbc9
      Aaron Conole authored
      The OVS module can operate in conjunction with various types of
      tunnel ports.  These are created as either explicit tunnel vport
      types, OR by creating a tunnel interface which acts as an anchor
      for the lightweight tunnel support.
      
      This patch adds the ability to add tunnel ports to an OVS
      datapath for testing various scenarios with tunnel ports.  With
      this addition, the vswitch "plumbing" will at least be able to
      push packets around using the tunnel vports.  Future patches
      will add support for setting required tunnel metadata for lwts
      in the datapath.  The end goal will be to push packets via these
      tunnels, and will be used in an upcoming commit for testing the
      path MTU.

      Linus found this pointer leak to userspace via zdi-disclosures@ and
      forwarded the notice to Netfilter maintainers, he appears as reporter
      because whoever found this issue never approached Netfilter

      When OOB data is in recvq, we can detect it with epoll by checking
      EPOLLPRI.
      
      This patch add checks for EPOLLPRI after every send() and recv() in
      all test cases.

      selftest: af_unix: Add SO_OOBINLINE test cases in msg_oob.c · 436352e8
      Kuniyuki Iwashima authored
      When SO_OOBINLINE is enabled on a socket, MSG_OOB can be recv()ed
      without MSG_OOB flag, and ioctl(SIOCATMARK) will behaves differently.
      
      This patch adds some test cases for SO_OOBINLINE.
      
      Note the new test cases found two bugs in TCP.
      
        1) After reading OOB data with non-inline mode, we can re-read
           the data by setting SO_OOBINLINE.
      
        #  RUN           msg_oob.no_peek.inline_oob_ahead_break ...

        ok 14 msg_oob.no_peek.inline_oob_ahead_break
      
        2) The head OOB data is dropped if SO_OOBINLINE is disabled
           if a new OOB data is queued.
      
        #  RUN           msg_oob.no_peek.inline_ex_oob_drop ...

      af_unix: Don't stop recv() at consumed ex-OOB skb. · 36893ef0
      Kuniyuki Iwashima authored
      Currently, recv() is stopped at a consumed OOB skb even if a new
      OOB skb is queued and we can ignore the old OOB skb.
      
        >>> from socket import *
        >>> c1, c2 = socket(AF_UNIX, SOCK_STREAM)
        >>> c1.send(b'hellowor', MSG_OOB)

        >>> c2.recv(1, MSG_OOB)  # consume OOB data stays at middle of recvq.

        2
        >>> c2.recv(10)          # recv() stops at the old consumed OOB
        b'hellowo'               # should be 'hellowol'
      
      manage_oob() should not stop recv() at the old consumed OOB skb if
      there is a new OOB data queued.
      
      Note that TCP behaviour is apparently wrong in this test case because
      we can recv() the same OOB data twice.

      Kuniyuki Iwashima authored
      While testing, I found some weird behaviour on the TCP side as well.
      
      For example, TCP drops the preceding OOB data when queueing a new
      OOB data if the old OOB data is at the head of recvq.
      
        #  RUN           msg_oob.no_peek.ex_oob_drop ...

        #  RUN           msg_oob.no_peek.ex_oob_drop_2 ...

        ok 10 msg_oob.no_peek.ex_oob_drop_2
      
      This patch allows AF_UNIX's MSG_OOB implementation to produce different
      results from TCP when operations are guarded with tcp_incompliant{}.

      af_unix: Don't stop recv(MSG_DONTWAIT) if consumed OOB skb is at the head. · 93c99f21
      Kuniyuki Iwashima authored
      Let's say a socket send()s "hello" with MSG_OOB and "world" without flags,
      
        >>> from socket import *
        >>> c1, c2 = socketpair(AF_UNIX)
        >>> c1.send(b'hello', MSG_OOB)
        5
        >>> c1.send(b'world')
        5
      
      and its peer recv()s "hell" and "o".
      
        >>> c2.recv(10)
        b'hell'
        >>> c2.recv(1, MSG_OOB)
        b'o'
      
      Now the consumed OOB skb stays at the head of recvq to return a correct
      value for ioctl(SIOCATMARK), which is broken now and fixed by a later
      patch.
      
      Then, if peer issues recv() with MSG_DONTWAIT, manage_oob() returns NULL,
      so recv() ends up with -EAGAIN.
      
        >>> c2.setblocking(False)  # This causes -EAGAIN even with available data
        >>> c2.recv(5)
        Traceback (most recent call last):
          File "<stdin>", line 1, in <module>
        BlockingIOError: [Errno 11] Resource temporarily unavailable
      
      However, next recv() will return the following available data, "world".
      
        >>> c2.recv(5)
        b'world'
      
      When the consumed OOB skb is at the head of the queue, we need to fetch
      the next skb to fix the weird behaviour.
      
      Note that the issue does not happen without MSG_DONTWAIT because we can
      retry after manage_oob().
      
      This patch also adds a test case that covers the issue.

      af_unix: Stop recv(MSG_PEEK) at consumed OOB skb. · b94038d8
      Kuniyuki Iwashima authored
      After consuming OOB data, recv() reading the preceding data must break at
      the OOB skb regardless of MSG_PEEK.
      
      Currently, MSG_PEEK does not stop recv() for AF_UNIX, and the behaviour is
      not compliant with TCP.
      
        >>> from socket import *
        >>> c1, c2 = socketpair(AF_UNIX)
        >>> c1.send(b'hello', MSG_OOB)

        b'hellworld'              # even with enough buffer.
      
      Let's fix it by returning NULL for consumed skb and unlinking it only if
      MSG_PEEK is not specified.
      
      This patch also adds test cases that add recv(MSG_PEEK) before each recv().

      AF_UNIX's MSG_OOB functionality lacked thorough testing, and we found
      some bizarre behaviour.
      
      The new selftest validates every MSG_OOB operation against TCP as a
      reference implementation.
      
      This patch adds only a few tests with basic send() and recv() that
      do not fail.
      
      The following patches will add more test cases for SO_OOBINLINE, SIGURG,

      test_unix_oob.c does not fully cover AF_UNIX's MSG_OOB functionality,

      Also, the test uses fork() to create message producer, and it's not

      Let's remove test_unix_oob.c and rewrite a new test.

      tracing/net_sched: NULL pointer dereference in perf_trace_qdisc_reset() · bab49231
      Yunseong Kim authored
      In the TRACE_EVENT(qdisc_reset) NULL dereference occurred from
      
       qdisc->dev_queue->dev <NULL> ->name
      
      This situation simulated from bunch of veths and Bluetooth disconnection
      and reconnection.
      
      During qdisc initialization, qdisc was being set to noop_queue.
      In veth_init_queue, the initial tx_num was reduced back to one,
      causing the qdisc reset to be called with noop, which led to the kernel
      panic.
      
      I've attached the GitHub gist link that C converted syz-execprogram
      source code and 3 log of reproduced vmcore-dmesg.
      
       https://gist.github.com/yskelg/cc64562873ce249cdd0d5a358b77d740
      
      Yeoreum and I use two fuzzing tool simultaneously.
      
      One process with syz-executor : https://github.com/google/syzkaller
      
       $ ./syz-execprog -executor=./syz-executor -repeat=1 -sandbox=setuid \
          -enable=none -collide=false log1
      
      The other process with perf fuzzer:
       https://github.com/deater/perf_event_tests/tree/master/fuzzer
      
       $ perf_event_tests/fuzzer/perf_fuzzer
      
      I think this will happen on the kernel version.
      
       Linux kernel version +v6.7.10, +v6.8, +v6.9 and it could happen in v6.10.
      
      This occurred from 51270d57. I think this patch is absolutely
      necessary. Previously, It was showing not intended string value of name.

      After applying our patch, I didn't find any kernel panic errors.
      
      We've found a simple reproducer

      However, without our patch applied, I tested upstream 6.10.0-rc3 kernel
      using the qdisc_reset event and the ip command on my qemu virtual machine.
      
      This 2 commands makes always kernel panic.

      Yeoreum and I don't know if the patch we wrote will fix the underlying

      So, we're sending this patch.

      Add a few tests exercising RSS context API.
      In addition to basic sanity checks, tests add RSS contexts,
      n-tuple rule to direct traffic to them (based on dst port),
      and qstats to make sure traffic landed where we expected.
      
      v2 adds a test for removing contexts out of order. When testing
      bnxt - either the new test or running more tests after the overlap
      test makes the device act strangely. To the point where it may start
      giving out ntuple IDs of 0 for all rules..

      selftests: drv-net: rss_ctx: add tests for RSS configuration and contexts · f898c16a
      Jakub Kicinski authored
      Add tests focusing on indirection table configuration and
      creating extra RSS contexts in drivers which support it.

      Note that rss_ctx.test_rss_context_out_of_order fails with the device
      I tested with, but it seems to be a device / driver bug.

      selftests: drv-net: add ability to wait for at least N packets to load gen · 94fecaa6
      Jakub Kicinski authored
      Teach the load generator how to wait for at least given number
      of packets to be received. This will be useful for filtering
      where we'll want to send a non-trivial number of packets and
      make sure they landed in right queues.

      selftests: drv-net: add helper to wait for HW stats to sync · af8e5164
      Jakub Kicinski authored
      Some devices DMA stats to the host periodically. Add a helper
      which can wait for that to happen, based on frequency reported
      by the driver in ethtool.

      selftests: drv-net: try to check if port is in use · 8b8fe280
      Jakub Kicinski authored
      We use random ports for communication. As Willem predicted
      this leads to occasional failures. Try to check if port is
      already in use by opening a socket and binding to that port.
