  • 163e3cb7d   net/rxrpc: Use BUG_ON ... Browse Code »

    if (...) BUG(); should be replaced with BUG_ON(...) when the test has no
    side-effects to allow a definition of BUG_ON that drops the code completely.

    The semantic patch that makes this change is as follows:
    (http://www.emn.fr/x-info/coccinelle/)

    //
    @ disable unlikely @ expression E,f; @@

    (
    if () { BUG(); }
    |
    - if (unlikely(E)) { BUG(); }
    + BUG_ON(E);
    )

    @@ expression E,f; @@

    (
    if () { BUG(); }
    |
    - if (E) { BUG(); }
    + BUG_ON(E);
    )
    //

  • 91cf45f02   [NET]: Add the helper kernel_sock_shutdown() ... Browse Code »

    ...and fix a couple of bugs in the NBD, CIFS and OCFS2 socket handlers.

    Looking at the sock->op->shutdown() handlers, it looks as if all of them
    take a SHUT_RD/SHUT_WR/SHUT_RDWR argument instead of the
    RCV_SHUTDOWN/SEND_SHUTDOWN arguments.
    Add a helper, and then define the SHUT_* enum to ensure that kernel users
    of shutdown() don't get confused.

  • c46f2334c   [SG] Get rid of __sg_mark_end() ... Browse Code »

    sg_mark_end() overwrites the page_link information, but all users want
    __sg_mark_end() behaviour where we just set the end bit. That is the most
    natural way to use the sg list, since you'll fill it in and then mark the
    end point.

    So change sg_mark_end() to only set the termination bit. Add a sg_magic
    debug check as well, and clear a chain pointer if it is set.

  • 6257ff217   [NET]: Forget the zero_it argument of sk_alloc() ... Browse Code »

    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.

  • 51c739d1f   [NET]: Fix incorrect sg_mark_end() calls. ... Browse Code »

    This fixes scatterlist corruptions added by

    commit 68e3f5dd4db62619fdbe520d36c9ebf62e672256
    [CRYPTO] users: Fix up scatterlist conversion errors

    The issue is that the code calls sg_mark_end() which clobbers the
    sg_page() pointer of the final scatterlist entry.

    The first part fo the fix makes skb_to_sgvec() do __sg_mark_end().

    After considering all skb_to_sgvec() call sites the most correct
    solution is to call __sg_mark_end() in skb_to_sgvec() since that is
    what all of the callers would end up doing anyways.

    I suspect this might have fixed some problems in virtio_net which is
    the sole non-crypto user of skb_to_sgvec().

    Other similar sg_mark_end() cases were converted over to
    __sg_mark_end() as well.

    Arguably sg_mark_end() is a poorly named function because it doesn't
    just "mark", it clears out the page pointer as a side effect, which is
    what led to these bugs in the first place.

    The one remaining plain sg_mark_end() call is in scsi_alloc_sgtable()
    and arguably it could be converted to __sg_mark_end() if only so that
    we can delete this confusing interface from linux/scatterlist.h

  • 76181c134   KEYS: Make request_key() and co fundamentally asynchronous ... Browse Code »

    Make request_key() and co fundamentally asynchronous to make it easier for
    NFS to make use of them. There are now accessor functions that do
    asynchronous constructions, a wait function to wait for construction to
    complete, and a completion function for the key type to indicate completion
    of construction.

    Note that the construction queue is now gone. Instead, keys under
    construction are linked in to the appropriate keyring in advance, and that
    anyone encountering one must wait for it to be complete before they can use
    it. This is done automatically for userspace.

    The following auxiliary changes are also made:

    (1) Key type implementation stuff is split from linux/key.h into
    linux/key-type.h.

    (2) AF_RXRPC provides a way to allocate null rxrpc-type keys so that AFS does
    not need to call key_instantiate_and_link() directly.

    (3) Adjust the debugging macros so that they're -Wformat checked even if
    they are disabled, and make it so they can be enabled simply by defining
    __KDEBUG to be consistent with other code of mine.

    (3) Documentation.

  • 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.

  • 457c4cbc5   [NET]: Make /proc/net per network namespace ... Browse Code »

    This patch makes /proc/net per network namespace. It modifies the global
    variables proc_net and proc_net_stat to be per network namespace.
    The proc_net file helpers are modified to take a network namespace argument,
    and all of their callers are fixed to pass &init_net for that argument.
    This ensures that all of the /proc/net files are only visible and
    usable in the initial network namespace until the code behind them
    has been updated to be handle multiple network namespaces.

    Making /proc/net per namespace is necessary as at least some files
    in /proc/net depend upon the set of network devices which is per
    network namespace, and even more files in /proc/net have contents
    that are relevant to a single network namespace.

  • 2c6b47de1   Cleanup non-arch xtime uses, use get_seconds() or current_kernel_time(). ... Browse Code »

    This avoids use of the kernel-internal "xtime" variable directly outside
    of the actual time-related functions. Instead, use the helper functions
    that we already have available to us.

    This doesn't actually change any behaviour, but this will allow us to
    fix the fact that "xtime" isn't updated very often with CONFIG_NO_HZ
    (because much of the realtime information is maintained as separate
    offsets to 'xtime'), which has caused interfaces that use xtime directly
    to get a time that is out of sync with the real-time clock by up to a
    third of a second or so.

  • 20c2df83d   mm: Remove slab destructors from kmem_cache_create(). ... Browse Code »

    Slab destructors were no longer supported after Christoph's
    c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
    BUGs for both slab and slub, and slob never supported them
    either.

    This rips out support for the dtor pointer from kmem_cache_create()
    completely and fixes up every single callsite in the kernel (there were
    about 224, not including the slab allocator definitions themselves,
    or the documentation references).
