    Wrong ax25_cb refcounting in ax25_send_frame() and by its callers can
    cause timer oopses (first reported with 2.6.29.6 kernel).

  • 1f731b637   rose_loopback_timer sets VC number <= ROSE_DEFAULT_MAXVC ... Browse Code »

    cat /proc/net/rose displayed a rose sockets abnormal lci value, i.e.
    greater than maximum number of VCs per neighbour allowed.
    This number prevents further test of lci value during rose operations.

    Example (lines shortened) :
    [bernard]# cat /proc/net/rose
    dest_addr dest_call src_addr src_call dev lci neigh st vs vr va
    * * 2080175520 F6BVP-1 rose0 000 00000 0 0 0 0
    2080175520 FPAD-0 2080175520 WP-0 rose0 FFE 00001 3 0 0 0

    Here are the default parameters :

    linux/include/net/rose.h:#define ROSE_DEFAULT_MAXVC 50 /* Maximum number of VCs per neighbour */
    linux/net/rose/af_rose.c:int sysctl_rose_maximum_vcs = ROSE_DEFAULT_MAXVC;

    With the following patch, rose_loopback_timer() attributes a VC number
    within limits.

    Now that sys_sysctl is a compatiblity wrapper around /proc/sys
    all sysctl strategy routines, and all ctl_name and strategy
    entries in the sysctl tables are unused, and can be

    In addition neigh_sysctl_register has been modified to no longer
    take a strategy argument and it's callers have been modified not

    commit 2b85a34e911bf483c27cfdd124aeb1605145dc80
    (net: No more expensive sock_hold()/sock_put() on each tx)
    changed initial sk_wmem_alloc value.

    Some protocols check sk_wmem_alloc value to determine if a timer
    must delay socket deallocation. We must take care of the sk_wmem_alloc
    value being one instead of zero when no write allocations are pending.

    Reported by Ingo Molnar, and full diagnostic from David Miller.

    This patch introduces three helpers to get read/write allocations
    and a followup patch will use these helpers to report correct
    write allocations to user.

  • 244f46ae6   rose: zero length frame filtering in af_rose.c ... Browse Code »

    Since changeset e79ad711a0108475c1b3a03815527e7237020b08 from mainline,
    >From David S. Miller,
    empty packet can be transmitted on connected socket for datagram protocols.

    However, this patch broke a high level application using ROSE network protocol with connected datagram.

    Bulletin Board Stations perform bulletins forwarding between BBS stations via ROSE network using a forward protocol.
    Now, if for some reason, a buffer in the application software happens to be empty at a specific moment,
    ROSE sends an empty packet via unfiltered packet socket.
    When received, this ROSE packet introduces perturbations of data exchange of BBS forwarding,
    for the application message forwarding protocol is waiting for something else.
    We agree that a more careful programming of the application protocol would avoid this situation and we are
    willing to debug it.
    But, as an empty frame is no use and does not have any meaning for ROSE protocol,
    we may consider filtering zero length data both when sending and receiving socket data.

    The proposed patch repaired BBS data exchange through ROSE network that were broken since 2.6.22.11 kernel.

  • e8a0464cc   netdev: Allocate multiple queues for TX. ... Browse Code »
    43

    alloc_netdev_mq() now allocates an array of netdev_queue
    structures for TX, based upon the queue_count argument.

    Furthermore, all accesses to the TX queues are now vectored
    through the netdev_get_tx_queue() and netdev_for_each_tx_queue()
    interfaces. This makes it easy to grep the tree for all
    things that want to get to a TX queue of a net device.

    Problem spots which are not really multiqueue aware yet, and
    only work with one queue, can easily be spotted by grepping
    for all netdev_get_tx_queue() calls that pass in a zero index.

  • fe2c802ab   rose: improving AX25 routing frames via ROSE network ... Browse Code »

    ROSE network is organized through nodes connected via hamradio or Internet.
    AX25 packet radio frames sent to a remote ROSE address destination are routed
    through these nodes.

    Without the present patch, automatic routing mechanism did not work optimally
    due to an improper parameter checking.

    rose_get_neigh() function is called either by rose_connect() or by
    rose_route_frame().

    In the case of a call from rose_connect(), f0 timer is checked to find if a connection
    is already pending. In that case it returns the address of the neighbour, or returns a NULL otherwise.

    When called by rose_route_frame() the purpose was to route a packet AX25 frame
    through an adjacent node given a destination rose address.
    However, in that case, t0 timer checked does not indicate if the adjacent node
    is actually connected even if the timer is not null. Thus, for each frame sent, the
    function often tried to start a new connexion even if the adjacent node was already connected.

    The patch adds a "new" parameter that is true when the function is called by
    rose route_frame().
    This instructs rose_get_neigh() to check node parameter "restarted".
    If restarted is true it means that the route to the destination address is opened via a neighbour
    node already connected.
    If "restarted" is false the function returns a NULL.
    In that case the calling function will initiate a new connection as before.

    This results in a fast routing of frames, from nodes to nodes, until
    destination is reached, as originaly specified by ROSE protocole.
