  • 824f1fbee   netfilter: Convert print_tuple functions to return void ... Browse Code »

    Since adding a new function to seq_file (seq_has_overflowed())
    there isn't any value for functions called from seq_show to
    return anything. Remove the int returns of the various
    print_tuple/_print_tuple functions.

  • 37246a583   netfilter: Remove return values for print_conntrack callbacks ... Browse Code »

    The seq_printf() and friends are having their return values removed.
    The print_conntrack() returns the result of seq_printf(), which is
    meaningless when seq_printf() returns void. Might as well remove the
    return values of print_conntrack() as well.

  • b22f5126a   netfilter: nf_conntrack_dccp: fix skb_header_pointer API usages ... Browse Code »

    Some occurences in the netfilter tree use skb_header_pointer() in
    the following way ...

    struct dccp_hdr _dh, *dh;
    ...
    skb_header_pointer(skb, dataoff, sizeof(_dh), &dh);

    ... where dh itself is a pointer that is being passed as the copy
    buffer. Instead, we need to use &_dh as the forth argument so that
    we're copying the data into an actual buffer that sits on the stack.

    Currently, we probably could overwrite memory on the stack (e.g.
    with a possibly mal-formed DCCP packet), but unintentionally, as
    we only want the buffer to be placed into _dh variable.

  • 30e0c6a6b   netfilter: nf_log: prepare net namespace support for loggers ... Browse Code »

    This patch adds netns support to nf_log and it prepares netns
    support for existing loggers. It is composed of four major
    changes.

    1) nf_log_register has been split to two functions: nf_log_register
    and nf_log_set. The new nf_log_register is used to globally
    register the nf_logger and nf_log_set is used for enabling
    pernet support from nf_loggers.

    Per netns is not yet complete after this patch, it comes in
    separate follow up patches.

    2) Add net as a parameter of nf_log_bind_pf. Per netns is not
    yet complete after this patch, it only allows to bind the
    nf_logger to the protocol family from init_net and it skips
    other cases.

    3) Adapt all nf_log_packet callers to pass netns as parameter.
    After this patch, this function only works for init_net.

    4) Make the sysctl net/netfilter/nf_log pernet.

    In (c296bb4 netfilter: nf_conntrack: refactor l4proto support for netns)
    the l4proto gre/dccp/udplite/sctp registration happened before the pernet
    subsystem, which is wrong.

    Register pernet subsystem before register L4proto since after register
    L4proto, init_conntrack may try to access the resources which allocated
    in register_pernet_subsys.

    Move the code that register/unregister l4proto to the
    module_init/exit context.

    Given that we have to modify some interfaces to accomodate
    these changes, it is a good time to use shorter function names
    for this using the nf_ct_* prefix instead of nf_conntrack_*,
    that is:

    nf_ct_l4proto_register
    nf_ct_l4proto_pernet_register
    nf_ct_l4proto_unregister
    nf_ct_l4proto_pernet_unregister

    We same many line breaks with it.

    In preparation for supporting the creation of network namespaces
    by unprivileged users, modify all of the per net sysctl exports
    and refuse to allow them to unprivileged users.

    This makes it safe for unprivileged users in general to access
    per net sysctls, and allows sysctls to be exported to unprivileged
    users on an individual basis as they are deemed safe.

    This patch prepares the namespace support for layer 4 protocol trackers.
    Basically, this modifies the following interfaces:

    * nf_ct_[un]register_sysctl
    * nf_conntrack_l4proto_[un]register

    to include the namespace parameter. We still use init_net in this patch
    to prepare the ground for follow-up patches for each layer 4 protocol
    tracker.

    We add a new net_id field to struct nf_conntrack_l4proto that is used
    to store the pernet_operations id for each layer 4 protocol tracker.

    Note that AF_INET6's protocols do not need to do sysctl compat. Thus,
    we only register compat sysctl when l4proto.l3proto != AF_INET6.

  • 509784623   netfilter: add cttimeout infrastructure for fine timeout tuning ... Browse Code »

    This patch adds the infrastructure to add fine timeout tuning
    over nfnetlink. Now you can use the NFNL_SUBSYS_CTNETLINK_TIMEOUT
    subsystem to create/delete/dump timeout objects that contain some
    specific timeout policy for one flow.

    The follow up patches will allow you attach timeout policy object
    to conntrack via the CT target and the conntrack extension
    infrastructure.

    This patch defines a new interface for l4 protocol trackers:

    unsigned int *(*get_timeouts)(struct net *net);

    that is used to return the array of unsigned int that contains
    the timeouts that will be applied for this flow. This is passed
    to the l4proto->new(...) and l4proto->packet(...) functions to
    specify the timeout policy.

    This interface allows per-net global timeout configuration
    (although only DCCP supports this by now) and it will allow
    custom custom timeout configuration by means of follow-up
    patches.

  • 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.
