  • 27852c26b   [SCTP]: Fix 'fast retransmit' to send a TSN only once. ... Browse Code »

    SCTP used to "fast retransmit" a TSN every time we hit the number
    of missing reports for the TSN. However the Implementers Guide
    specifies that we should only "fast retransmit" a given TSN once.
    Subsequent retransmits should be timeouts only. Also change the
    number of missing reports to 3 as per the latest IG(similar to TCP).

  • e2c2fc2c8   [SCTP]: heartbeats exceed maximum retransmssion limit ... Browse Code »

    The number of HEARTBEAT chunks that an association may transmit is
    limited by Association.Max.Retrans count; however, the code allows
    us to send one extra heartbeat.

    This patch limits the number of heartbeats to the maximum count.

  • 81845c21d   [SCTP]: correct the number of INIT retransmissions ... Browse Code »

    We currently count the initial INIT/COOKIE_ECHO chunk toward the
    retransmit count and thus sends a total of sctp_max_retrans_init chunks.
    The correct behavior is to retransmit the chunk sctp_max_retrans_init in
    addition to sending the original.

    Validate and update the sk in sctp_rcv() to avoid the race where an
    assoc/ep could move to a different socket after we get the sk, but before
    the skb is added to the backlog.

    Also migrate the skb's in backlog queue to new sk when doing a peeloff.

  • 313e7b4d2   [SCTP]: Fix machine check/connection hang on IA64. ... Browse Code »

    sctp_unpack_cookie used an on-stack array called digest as a result/out
    parameter in the call to crypto_hmac. However, hmac code
    (crypto_hmac_final)
    assumes that the 'out' argument is in virtual memory (identity mapped
    region)
    and can use virt_to_page call on it. This does not work with the on-stack
    declared digest. The problems observed so far have been:
    a) incorrect hmac digest
    b) machine check and hardware reset.

    Solution is to define the digest in an identity mapped region by
    kmalloc'ing
    it. We can do this once as part of the endpoint structure and re-use it
    when
    verifying the SCTP cookie.

  • 38b0e42ab   [SCTP]: Fix sctp_assoc_seq_show() panics on big-endian systems. ... Browse Code »

    This patch corrects the panic by casting the argument to the
    pointer of correct size. On big-endian systems we ended up loading
    only 32 bits of data because we are treating the pointer as an int*.
    By treating this pointer as loff_t*, we'll load the full 64 bits
    and then let regular integer demotion take place which will give us
    the correct value.

  • 49392e5ec   [SCTP]: sctp doesn't show all associations/endpoints in /proc ... Browse Code »

    When creating a very large number of associations (and endpoints),
    /proc/assocs and /proc/eps will not show all of them. As a result
    netstat will not show all of the either. This is particularly evident
    when creating 1000+ associations (or endpoints). As an example with
    1500 tcp style associations over loopback, netstat showed 1420 on my
    system instead of 3000.

    The reason for this is that the seq_operations start method is invoked
    multiple times bacause of the amount of data that is provided. The
    start method always increments the position parameter and since we use
    the position as the hash bucket id, we end up skipping hash buckets.

    This patch corrects this situation and get's rid of the silly hash-1
    decrement.

  • 90ddc4f04   [NET]: move struct proto_ops to const ... Browse Code »

    I noticed that some of 'struct proto_ops' used in the kernel may share
    a cache line used by locks or other heavily modified data. (default
    linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at
    least)

    This patch makes sure a 'struct proto_ops' can be declared as const,
    so that all cpus can share all parts of it without false sharing.

    This is not mandatory : a driver can still use a read/write structure
    if it needs to (and eventually a __read_mostly)

    I made a global stubstitute to change all existing occurences to make
    them const.

    This should reduce the possibility of false sharing on SMP, and
    speedup some socket system calls.

  • 23ec47a08   [SCTP]: Fix potential NULL pointer dereference in sctp_v4_get_saddr ... Browse Code »

    It is possible to get to sctp_v4_get_saddr() without a valid
    association. This happens when processing OOTB packets and
    the cached route entry is no longer valid.
    However, when responding to OOTB packets we already properly
    set the source address based on the information in the OOTB
    packet. So, if we we get to sctp_v4_get_saddr() without an
    association we can simply return.

  • 670c02c2b   [NET]: Wider use of for_each_*cpu() ... Browse Code »

    In 'net' change the explicit use of for-loops and NR_CPUS into the
    general for_each_cpu() or for_each_online_cpu() constructs, as
    appropriate. This widens the scope of potential future optimizations
    of the general constructs, as well as takes advantage of the existing
    optimizations of first_cpu() and next_cpu(), which is advantageous
    when the true CPU count is much smaller than NR_CPUS.

  • e5ed63991   [IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnl ... Browse Code »

    The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
    introduces __in_dev_get_rcu() to cover the second case.

    1) RCU with refcnt should use in_dev_get().
    2) RCU without refcnt should use __in_dev_get_rcu().
    3) All others must hold RTNL and use __in_dev_get_rtnl().

    There is one exception in net/ipv4/route.c which is in fact a pre-existing
    race condition. I've marked it as such so that we remember to fix it.

    This patch is based on suggestions and prior work by Suzanne Wood and
    Paul McKenney.
