  • nr_route.ndigis is unsigned int so the nr_route.ndigis < 0 expression is
    never true and can be dropped. Doing the nr_ax25_dev_get call later
    allows the nr_route.ndigis test to bail out without having to dev_put.

  • struct nr_route_struct's mnemonic permits a string of up to 7 bytes to be
    used. If userland passes a not zero terminated string to the kernel adding
    a node to the routing table might result in the kernel attempting to read
    copy a too long string.

    Mnemonic is part of the NET/ROM routing protocol; NET/ROM routing table
    updates only broadcast 6 bytes. The 7th byte in the mnemonic array exists
    only as a \0 termination character for the kernel code's convenience.

    Fixed by rejecting mnemonic strings that have no terminating \0 in the first
    7 characters. Do this test only NETROM_NODE to avoid breaking NETROM_NEIGH
    where userland might passing an uninitialized mnemonic field.

  • Define a new function to return the waitqueue of a "struct sock".

    static inline wait_queue_head_t *sk_sleep(struct sock *sk)
    {
    return sk->sk_sleep;
    }

    Change all read occurrences of sk_sleep by a call to this function.

    Needed for a future RCU conversion. sk_sleep wont be a field directly
    available.

  • …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • 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
    revmoed.

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

  • The generic __sock_create function has a kern argument which allows the
    security system to make decisions based on if a socket is being created by
    the kernel or by userspace. This patch passes that flag to the
    net_proto_family specific create function, so it can do the same thing.

  • Adds RCU management to the list of netdevices.

    Convert some for_each_netdev() users to RCU version, if
    it can avoid read_lock-ing dev_base_lock

    Ie:
    read_lock(&dev_base_loack);
    for_each_netdev(net, dev)
    some_action();
    read_unlock(&dev_base_lock);

    becomes :

    rcu_read_lock();
    for_each_netdev_rcu(net, dev)
    some_action();
    rcu_read_unlock();

  • The static variable used by nr_call_to_digi might result in corruption if
    multiple threads are trying to usee a node or neighbour via ioctl. Fixed
    by having the caller pass a structure in. This is safe because nr_add_node
    rsp. nr_add_neigh will allocate a permanent structure, if needed.

    (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.

  • Wrap access to task credentials so that they can be separated more easily from
    the task_struct during the introduction of COW creds.

    Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().

    Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more
    sense to use RCU directly rather than a convenient wrapper; these will be
    addressed by later patches.

  • 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.
