  • d265fef6d   tipc: Remove obsolete native API files and exports ... Browse Code »

    As part of the removal of TIPC's native API support it is no longer
    necessary for TIPC to export symbols for routines that can be called
    by kernel-based applications, nor for it to have header files that
    kernel-based applications can include to access the declarations for
    those routines. This commit eliminates the exporting of symbols by
    TIPC and migrates the contents of each obsolete native API include
    file into its corresponding non-native API equivalent.

    The code which was migrated in this commit was migrated intact, in
    that there are no technical changes combined with the relocation.

  • b2abd4c03   tipc: Optimize handling excess content on incoming messages ... Browse Code »

    Remove code that trimmed excess trailing info from incoming messages
    arriving over an Ethernet interface. TIPC now ignores the extra info
    while the message is being processed by the node, and only trims it off
    if the message is retransmitted to another node. (This latter step is
    done to ensure the extra info doesn't cause the sk_buff to exceed the
    outgoing interface's MTU limit.) The outgoing buffer is guaranteed to
    be linear.

  • d1fb62796   tipc: Fix misleading error code when enabling Ethernet bearers ... Browse Code »

    Cause TIPC to return EAGAIN if it is unable to enable a new Ethernet
    bearer because one or more recently disabled Ethernet bearers are
    temporarily consuming resources during shut down. (The previous error
    code, EDQUOT, is now returned only if all available Ethernet bearer
    data structures are fully enabled at the time the request to enable an
    additional bearer is received.)

  • 9fbfca013   tipc: Ensure outgoing messages on Ethernet have sufficient headroom ... Browse Code »

    Add code to expand the headroom of an outgoing TIPC message if the
    sk_buff has insufficient room to hold the header for the associated
    Ethernet device. This change is necessary to ensure that messages
    TIPC does not create itself (eg. incoming messages that are being
    routed to another node) do not cause problems, since TIPC has no
    control over the amount of headroom available in such messages.

  • 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.

    This converts pretty much everything to print_mac. There were
    a few things that had conflicts which I have just dropped for
    now, no harm done.

    I've built an allyesconfig with this and looked at the files
    that weren't built very carefully, but it's a huge patch.

  • 0e35fd5e5   tipc: Eliminate improper use of TIPC_OK error code ... Browse Code »

    This patch corrects many places where TIPC routines indicated
    successful completion by returning TIPC_OK instead of 0.
    (The TIPC_OK symbol has the value 0, but it should only be used
    in contexts that deal with the error code field of a TIPC
    message header.)

  • 881d966b4   [NET]: Make the device list and device lookups per namespace. ... Browse Code »

    This patch makes most of the generic device layer network
    namespace safe. This patch makes dev_base_head a
    network namespace variable, and then it picks up
    a few associated variables. The functions:
    dev_getbyhwaddr
    dev_getfirsthwbytype
    dev_get_by_flags
    dev_get_by_name
    __dev_get_by_name
    dev_get_by_index
    __dev_get_by_index
    dev_ioctl
    dev_ethtool
    dev_load
    wireless_process_ioctl

    were modified to take a network namespace argument, and
    deal with it.

    vlan_ioctl_set and brioctl_set were modified so their
    hooks will receive a network namespace argument.

    So basically anthing in the core of the network stack that was
    affected to by the change of dev_base was modified to handle
    multiple network namespaces. The rest of the network stack was
    simply modified to explicitly use &init_net the initial network
    namespace. This can be fixed when those components of the network
    stack are modified to handle multiple network namespaces.

    For now the ifindex generator is left global.

    Fundametally ifindex numbers are per namespace, or else
    we will have corner case problems with migration when
    we get that far.

    At the same time there are assumptions in the network stack
    that the ifindex of a network device won't change. Making
    the ifindex number global seems a good compromise until
    the network stack can cope with ifindex changes when
    you change namespaces, and the like.

  • e9dc86534   [NET]: Make device event notification network namespace safe ... Browse Code »

    Every user of the network device notifiers is either a protocol
    stack or a pseudo device. If a protocol stack that does not have
    support for multiple network namespaces receives an event for a
    device that is not in the initial network namespace it quite possibly
    can get confused and do the wrong thing.

    To avoid problems until all of the protocol stacks are converted
    this patch modifies all netdev event handlers to ignore events on
    devices that are not in the initial network namespace.

    As the rest of the code is made network namespace aware these
    checks can be removed.

    This patch modifies every packet receive function
    registered with dev_add_pack() to drop packets if they
    are not from the initial network namespace.

    This should ensure that the various network stacks do
    not receive packets in a anything but the initial network
    namespace until the code has been converted and is ready
    for them.

  • f3ec75f62   [TIPC]: Improved support for Ethernet traffic filtering ... Browse Code »

    This patch simplifies TIPC's Ethernet receive routine to take
    advantage of information already present in each incoming sk_buff
    indicating whether the packet was explicitly sent to the interface,
    has been broadcast to all interfaces, or was picked up because the
    interface is in promiscous mode.

    This new approach also fixes the problem of TIPC accepting unwanted
    traffic through UML's multicast-based Ethernet interfaces (which
    deliver traffic in a promiscuous manner even if the interface is
    not configured to be promiscuous).
