  • f545a38f7   net: add a limit parameter to sk_add_backlog() ... Browse Code »

    sk_add_backlog() & sk_rcvqueues_full() hard coded sk_rcvbuf as the
    memory limit. We need to make this limit a parameter for TCP use.

    No functional change expected in this patch, all callers still using the
    old sk_rcvbuf limit.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …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.

  • 52d58aef5   llc: replace the socket list with a local address based hash ... Browse Code »

    For the cases where a lot of interfaces are used in conjunction with a
    lot of LLC sockets bound to the same SAP, the iteration of the socket
    list becomes prohibitively expensive.

    Replacing the list with a a local address based hash significantly
    improves the bind and listener lookup operations as well as the
    datagram delivery.

    Connected sockets delivery is also improved, but this patch does not
    address the case where we have lots of sockets with the same local
    address connected to different remote addresses.

    In order to keep the socket sanity checks alive and fast a socket
    counter was added to the SAP structure.

  • b76f5a842   llc: convert the socket list to RCU locking ... Browse Code »

    For the reclamation phase we use the SLAB_DESTROY_BY_RCU mechanism,
    which require some extra checks in the lookup code:

    a) If the current socket was released, reallocated & inserted in
    another list it will short circuit the iteration for the current list,
    thus we need to restart the lookup.

    b) If the current socket was released, reallocated & inserted in the
    same list we just need to recheck it matches the look-up criteria and
    if not we can skip to the next element.

    In this case there is no need to restart the lookup, since sockets are
    inserted at the start of the list and the worst that will happen is
    that we will iterate throught some of the list elements more then
    once.

    Note that the /proc and multicast delivery was not yet converted to
    RCU, it still uses spinlocks for protection.

    Many-many code in the kernel initialized the timer->function
    and timer->data together with calling init_timer(timer). There
    is already a helper for this. Use it for networking code.

    The patch is HUGE, but makes the code 130 lines shorter

    Finally, the zero_it argument can be completely removed from
    the callers and from the function prototype.

    Besides, fix the checkpatch.pl warnings about using the
    assignments inside if-s.

    This patch is rather big, and it is a part of the previous one.
    I splitted it wishing to make the patches more readable. Hope
    this particular split helped.

  • 1b8d7ae42   [NET]: Make socket creation namespace safe. ... Browse Code »

    This patch passes in the namespace a new socket should be created in
    and has the socket code do the appropriate reference counting. By
    virtue of this all socket create methods are touched. In addition
    the socket create methods are modified so that they will fail if
    you attempt to create a socket in a non-default network namespace.

    Failing if we attempt to create a socket outside of the default
    network namespace ensures that as we incrementally make the network stack
    network namespace aware we will not export functionality that someone
    has not audited and made certain is network namespace safe.
    Allowing us to partially enable network namespaces before all of the
    exotic protocols are supported.

    Any protocol layers I have missed will fail to compile because I now
    pass an extra parameter into the socket creation code.

    - added typedef unsigned int __nocast gfp_t;

    - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
    the same warnings as far as sparse is concerned, doesn't change
    generated code (from gcc point of view we replaced unsigned int with
    typedef) and documents what's going on far better.

    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.

    drivers which Francois Romieu fixed

    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!
