  • c7c694d19   [AX.25]: Fix potencial memory hole. ... Browse Code »

    If the AX.25 dialect chosen by the sysadmin is set to DAMA master / 3
    (or DAMA slave / 2, if CONFIG_AX25_DAMA_SLAVE=n) ax25_kick() will fall
    through the switch statement without calling ax25_send_iframe() or any
    other function that would eventually free skbn thus leaking the packet.

    Fix by restricting the sysctl inferface to allow only actually supported
    AX.25 dialects.

    The system administration mistake needed for this to happen is rather
    unlikely, so this is an uncritical hole.

    Coverity #651.

  • b5e5fa5e0   [NET]: Add a dev_ioctl() fallback to sock_ioctl() ... Browse Code »

    Currently all network protocols need to call dev_ioctl as the default
    fallback in their ioctl implementations. This patch adds a fallback
    to dev_ioctl to sock_ioctl if the protocol returned -ENOIOCTLCMD.
    This way all the procotol ioctl handlers can be simplified and we don't
    need to export dev_ioctl.

  • 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.

    Since changeset 98a82febb6340466824c3a453738d4fbd05db81a AX.25 is passing
    received IP and ARP packets to the stack through netif_rx() but we don't
    set the skb->mac.raw to right value which may result in a crash with
    applications that use a packet socket.

  • baed16a7f   [AX.25]: Make asc2ax() thread-proof ... Browse Code »

    Asc2ax was still using a static buffer for all invocations which isn't
    exactly SMP-safe. Change asc2ax to take an additional result buffer as
    the argument. Change all callers to provide such a buffer.

    This one only really is a fix for ROSE and as per recent discussions
    there's still much more to fix in ROSE ...

  • 98a82febb   [AX25/NETROM]: Cleanup direct calls into IP stack ... Browse Code »

    Get rid of the calls to ip_rcv and arp_rcv which were layering
    violations anyway. With those being replaced by netif_rx, less parts
    of AX.25 and relatives depend on INET support actually being enabled.
    This also will make PF_PACKET sockets work for IP and ARP packets
    received over AX.25 and for IP packets over NET/ROM.

    Lots of places just needs the states, not even linux/tcp.h, where this
    enum was, needs it.

    This speeds up development of the refactorings as less sources are
    rebuilt when things get moved from net/tcp.h.

  • f2ccd8fa0   [NET]: Kill skb->real_dev ... Browse Code »

    Bonding just wants the device before the skb_bond()
    decapsulation occurs, so simply pass that original
    device into packet_type->func() as an argument.

    It remains to be seen whether we can use this same
    exact thing to get rid of skb->input_dev as well.

  • 8728b834b   [NET]: Kill skb->list ... Browse Code »

    Remove the "list" member of struct sk_buff, as it is entirely
    redundant. All SKB list removal callers know which list the
    SKB is on, so storing this in sk_buff does nothing other than
    taking up some space.

    Two tricky bits were SCTP, which I took care of, and two ATM
    drivers which Francois Romieu fixed
    up.

  • 01d7dd0e9   [AX25]: UID fixes ... Browse Code »

    o Brown paperbag bug - ax25_findbyuid() was always returning a NULL pointer
    as the result. Breaks ROSE completly and AX.25 if UID policy set to deny.

    o While the list structure of AX.25's UID to callsign mapping table was
    properly protected by a spinlock, it's elements were not refcounted
    resulting in a race between removal and usage of an element.

  • 53b924b31   [NET]: Fix socket bitop damage ... Browse Code »

    The socket flag cleanups that went into 2.6.12-rc1 are basically oring
    the flags of an old socket into the socket just being created.
    Unfortunately that one was just initialized by sock_init_data(), so already
    has SOCK_ZAPPED set. As the result zapped sockets are created and all
    incoming connection will fail due to this bug which again was carefully
    replicated to at least AX.25, NET/ROM or ROSE.

    In order to keep the abstraction alive I've introduced sock_copy_flags()
    to copy the socket flags from one sockets to another and used that
    instead of the bitwise copy thing. Anyway, the idea here has probably
    been to copy all flags, so sock_copy_flags() should be the right thing.
    With this the ham radio protocols are usable again, so I hope this will
    make it into 2.6.13.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
