  • 2692ba61a   sctp: fix incorrect overflow check on autoclose ... Browse Code »
    1

    Commit 8ffd3208 voids the previous patches f6778aab and 810c0719 for
    limiting the autoclose value. If userspace passes in -1 on 32-bit
    platform, the overflow check didn't work and autoclose would be set
    to 0xffffffff.

    This patch defines a max_autoclose (in seconds) for limiting the value
    and exposes it through sysctl, with the following intentions.

    1) Avoid overflowing autoclose * HZ.

    2) Keep the default autoclose bound consistent across 32- and 64-bit
    platforms (INT_MAX / HZ in this patch).

    3) Keep the autoclose value consistent between setsockopt() and
    getsockopt() calls.

  • cd4fcc704   sctp: ABORT if receive, reassmbly, or reodering queue is not empty while closing socket ... Browse Code »

    Trigger user ABORT if application closes a socket which has data
    queued on the socket receive queue or chunks waiting on the
    reassembly or ordering queue as this would imply data being lost
    which defeats the point of a graceful shutdown.

    This behavior is already practiced in TCP.

    We do not check the input queue because that would mean to parse
    all chunks on it to look for unacknowledged data which seems too
    much of an effort. Control chunks or duplicated chunks may also
    be in the input queue and should not be stopping a graceful
    shutdown.

  • 8a07eb0a5   sctp: Add ASCONF operation on the single-homed host ... Browse Code »

    In this case, the SCTP association transmits an ASCONF packet
    including addition of the new IP address and deletion of the old
    address. This patch implements this functionality.
    In this case, the ASCONF chunk is added to the beginning of the
    queue, because the other chunks cannot be transmitted in this state.

    in the SCTP stack with address events in the host computer,
    which is called auto_asconf.

  • 9914ae3ca   sctp: cache the ipv6 source after route lookup ... Browse Code »

    The ipv6 routing lookup does give us a source address,
    but instead of filling it into the dst, it's stored in
    the flowi. We can use that instead of going through the
    entire source address selection again.
    Also the useless ->dst_saddr member of sctp_pf is removed.
    And sctp_v6_dst_saddr() is removed, instead by introduce
    sctp_v6_to_addr(), which can be reused to cleanup some dup
    code.

    Two user-controlled allocations in SCTP are subsequently dereferenced as
    sockaddr structs, without checking if the dereferenced struct members fall
    beyond the end of the allocated chunk. There doesn't appear to be any
    information leakage here based on how these members are used and
    additional checking, but it's still worth fixing.

    (Dropped the infiniband part, because Tetsuo modified the related code,
    I will send a separate patch for it once this is accepted.)

    This patch introduces /proc/sys/net/ipv4/ip_local_reserved_ports which
    allows users to reserve ports for third-party applications.

    The reserved ports will not be used by automatic port assignments
    (e.g. when calling connect() or bind() with port number 0). Explicit
    port allocation behavior is unchanged.

  • 438154823   net: sock_def_readable() and friends RCU conversion ... Browse Code »

    sk_callback_lock rwlock actually protects sk->sk_sleep pointer, so we
    need two atomic operations (and associated dirtying) per incoming
    packet.

    RCU conversion is pretty much needed :

    1) Add a new structure, called "struct socket_wq" to hold all fields
    that will need rcu_read_lock() protection (currently: a
    wait_queue_head_t and a struct fasync_struct pointer).

    [Future patch will add a list anchor for wakeup coalescing]

    2) Attach one of such structure to each "struct socket" created in
    sock_alloc_inode().

    3) Respect RCU grace period when freeing a "struct socket_wq"

    4) Change sk_sleep pointer in "struct sock" by sk_wq, pointer to "struct
    socket_wq"

    5) Change sk_sleep() function to use new sk->sk_wq instead of
    sk->sk_sleep

    6) Change sk_has_sleeper() to wq_has_sleeper() that must be used inside
    a rcu_read_lock() section.

    7) Change all sk_has_sleeper() callers to :
    - Use rcu_read_lock() instead of read_lock(&sk->sk_callback_lock)
    - Use wq_has_sleeper() to eventually wakeup tasks.
    - Use rcu_read_unlock() instead of read_unlock(&sk->sk_callback_lock)

    8) sock_wake_async() is modified to use rcu protection as well.

    9) Exceptions :
    macvtap, drivers/net/tun.c, af_unix use integrated "struct socket_wq"
    instead of dynamically allocated ones. They dont need rcu freeing.

    Some cleanups or followups are probably needed, (possible
    sk_callback_lock conversion to a spinlock for example...).
