  • 0479ea0ea   Fix incorrect prototype for ipxrtr_route_packet() ... Browse Code »

    The function ipxrtr_route_packet() takes a 'len' argument of type
    size_t. However, its prototype in af_ipx.c incorrectly suggests that the
    corresponding argument is of type 'int' instead.

    Discovered by building with --combine and letting the compiler see it
    all at once.

  • badff6d01   [SK_BUFF]: Introduce skb_reset_transport_header(skb) ... Browse Code »

    For the common, open coded 'skb->h.raw = skb->data' operation, so that we can
    later turn skb->h.raw into a offset, reducing the size of struct sk_buff in
    64bit land while possibly keeping it as a pointer on 32bit.

    This one touches just the most simple cases:

    skb->h.raw = skb->data;
    skb->h.raw = {skb_push|[__]skb_pull}()

    The next ones will handle the slightly more "complex" cases.

  • b7aa0bf70   [NET]: convert network timestamps to ktime_t ... Browse Code »

    We currently use a special structure (struct skb_timeval) and plain
    'struct timeval' to store packet timestamps in sk_buffs and struct
    sock.

    This has some drawbacks :
    - Fixed resolution of micro second.
    - Waste of space on 64bit platforms where sizeof(struct timeval)=16

    I suggest using ktime_t that is a nice abstraction of high resolution
    time services, currently capable of nanosecond resolution.

    As sizeof(ktime_t) is 8 bytes, using ktime_t in 'struct sock' permits
    a 8 byte shrink of this structure on 64bit architectures. Some other
    structures also benefit from this size reduction (struct ipq in
    ipv4/ip_fragment.c, struct frag_queue in ipv6/reassembly.c, ...)

    Once this ktime infrastructure adopted, we can more easily provide
    nanosecond resolution on top of it. (ioctl SIOCGSTAMPNS and/or
    SO_TIMESTAMPNS/SCM_TIMESTAMPNS)

    Note : this patch includes a bug correction in
    compat_sock_get_timestamp() where a "err = 0;" was missing (so this
    syscall returned -ENOENT instead of 0)

  • 0b4d41471   [PATCH] sysctl: remove insert_at_head from register_sysctl ... Browse Code »

    The semantic effect of insert_at_head is that it would allow new registered
    sysctl entries to override existing sysctl entries of the same name. Which is
    pain for caching and the proc interface never implemented.

    I have done an audit and discovered that none of the current users of
    register_sysctl care as (excpet for directories) they do not register
    duplicate sysctl entries.

    So this patch simply removes the support for overriding existing entries in
    the sys_sysctl interface since no one uses it or cares and it makes future
    enhancments harder.

    Many struct file_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

    Fixes a null pointer dereference when unloading the ipx module.

    On initialization of the ipx module, registering certain packet
    types can fail. When this happens, unloading the module later
    dereferences NULL pointers. This patch fixes that. Please apply.

  • 02e60370d   [IPX]: Annotate and fix IPX checksum ... Browse Code »

    Calculation of IPX checksum got buggered about 2.4.0. The old variant
    mangled the packet; that got fixed, but calculation itself got buggered.
    Restored the correct logics, fixed a subtle breakage we used to have even
    back then: if the sum is 0 mod 0xffff, we want to return 0, not 0xffff.
    The latter has special meaning for IPX (cheksum disabled). Observation
    (and obvious fix) nicked from history of FreeBSD ipx_cksum.c...

  • 7b1ba8de5   [IPX]: Another nonlinear receive fix ... Browse Code »

    Need to check some more cases in IPX receive. If the skb is purely
    fragments, the IPX header needs to be extracted. The function
    pskb_may_pull() may in theory invalidate all the pointers in the skb,
    so references to ipx header must be refreshed.

  • f6c90b71a   [NET]: Fix ipx/econet/appletalk/irda ioctl crashes ... Browse Code »

    Fix kernel oopses whenever somebody issues compatible ioctl on AppleTalk,
    Econet, IPX or IRDA socket. For AppleTalk/Econet/IRDA it restores state
    in which these sockets were before compat_ioctl was introduced to the socket
    ops, for IPX it implements support for 4 ioctls which were not implemented
    before - as these ioctls use structures which match between 32bit and 64bit
    userspace, no special code is needed, just call 64bit ioctl handler.

  • b5e5fa5e0   [NET]: Add a dev_ioctl() fallback to sock_ioctl() ... Browse Code »

    Currently all network protocols need to call dev_ioctl as the default
    fallback in their ioctl implementations. This patch adds a fallback
    to dev_ioctl to sock_ioctl if the protocol returned -ENOIOCTLCMD.
    This way all the procotol ioctl handlers can be simplified and we don't
    need to export dev_ioctl.

  • 90ddc4f04   [NET]: move struct proto_ops to const ... Browse Code »

    I noticed that some of 'struct proto_ops' used in the kernel may share
    a cache line used by locks or other heavily modified data. (default
    linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at
    least)

    This patch makes sure a 'struct proto_ops' can be declared as const,
    so that all cpus can share all parts of it without false sharing.

    This is not mandatory : a driver can still use a read/write structure
    if it needs to (and eventually a __read_mostly)

    I made a global stubstitute to change all existing occurences to make
    them const.

    This should reduce the possibility of false sharing on SMP, and
    speedup some socket system calls.

  • 6a2e9b738   [NET]: move config options out to individual protocols ... Browse Code »

    Move the protocol specific config options out to the specific protocols.
    With this change net/Kconfig now starts to become readable and serve as a
    good basis for further re-structuring.

    The menu structure is left almost intact, except that indention is
    fixed in most cases. Most visible are the INET changes where several
    "depends on INET" are replaced with a single ifdef INET / endif pair.

    Several new files were created to accomplish this change - they are
    small but serve the purpose that config options are now distributed
    out where they belongs.

    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!
