  • cbbd7d4f3   [INET]: Fix incorrect "inet_sock->is_icsk" assignment. ... Browse Code »

    The inet_create() and inet6_create() functions incorrectly set the
    inet_sock->is_icsk field. Both functions assume that the is_icsk field is
    large enough to hold at least a INET_PROTOSW_ICSK value when it is actually
    only a single bit. This patch corrects the assignment by doing a boolean
    comparison whose result will safely fit into a single bit field.

  • ba4e58eca   [NET]: Supporting UDP-Lite (RFC 3828) in Linux ... Browse Code »

    This is a revision of the previously submitted patch, which alters
    the way files are organized and compiled in the following manner:

    * UDP and UDP-Lite now use separate object files
    * source file dependencies resolved via header files
    net/ipv{4,6}/udp_impl.h
    * order of inclusion files in udp.c/udplite.c adapted
    accordingly

    [NET/IPv4]: Support for the UDP-Lite protocol (RFC 3828)

    This patch adds support for UDP-Lite to the IPv4 stack, provided as an
    extension to the existing UDPv4 code:
    * generic routines are all located in net/ipv4/udp.c
    * UDP-Lite specific routines are in net/ipv4/udplite.c
    * MIB/statistics support in /proc/net/snmp and /proc/net/udplite
    * shared API with extensions for partial checksum coverage

    [NET/IPv6]: Extension for UDP-Lite over IPv6

    It extends the existing UDPv6 code base with support for UDP-Lite
    in the same manner as per UDPv4. In particular,
    * UDPv6 generic and shared code is in net/ipv6/udp.c
    * UDP-Litev6 specific extensions are in net/ipv6/udplite.c
    * MIB/statistics support in /proc/net/snmp6 and /proc/net/udplite6
    * support for IPV6_ADDRFORM
    * aligned the coding style of protocol initialisation with af_inet6.c
    * made the error handling in udpv6_queue_rcv_skb consistent;
    to return `-1' on error on all error cases
    * consolidation of shared code

    [NET]: UDP-Lite Documentation and basic XFRM/Netfilter support

    The UDP-Lite patch further provides
    * API documentation for UDP-Lite
    * basic xfrm support
    * basic netfilter support for IPv4 and IPv6 (LOG target)

  • 72a3effaf   [NET]: Size listen hash tables using backlog hint ... Browse Code »

    We currently allocate a fixed size (TCP_SYNQ_HSIZE=512) slots hash table for
    each LISTEN socket, regardless of various parameters (listen backlog for
    example)

    On x86_64, this means order-1 allocations (might fail), even for 'small'
    sockets, expecting few connections. On the contrary, a huge server wanting a
    backlog of 50000 is slowed down a bit because of this fixed limit.

    This patch makes the sizing of listen hash table a dynamic parameter,
    depending of :
    - net.core.somaxconn tunable (default is 128)
    - net.ipv4.tcp_max_syn_backlog tunable (default : 256, 1024 or 128)
    - backlog value given by user application (2nd parameter of listen())

    For large allocations (bigger than PAGE_SIZE), we use vmalloc() instead of
    kmalloc().

    We still limit memory allocation with the two existing tunables (somaxconn &
    tcp_max_syn_backlog). So for standard setups, this patch actually reduce RAM
    usage.

  • a430a43d0   [NET] gso: Fix up GSO packets with broken checksums ... Browse Code »

    Certain subsystems in the stack (e.g., netfilter) can break the partial
    checksum on GSO packets. Until they're fixed, this patch allows this to
    work by recomputing the partial checksums through the GSO mechanism.

    Once they've all been converted to update the partial checksum instead of
    clearing it, this workaround can be removed.

  • 576a30eb6   [NET]: Added GSO header verification ... Browse Code »

    When GSO packets come from an untrusted source (e.g., a Xen guest domain),
    we need to verify the header integrity before passing it to the hardware.

    Since the first step in GSO is to verify the header, we can reuse that
    code by adding a new bit to gso_type: SKB_GSO_DODGY. Packets with this
    bit set can only be fed directly to devices with the corresponding bit
    NETIF_F_GSO_ROBUST. If the device doesn't have that bit, then the skb
    is fed to the GSO engine which will allow the packet to be sent to the
    hardware if it passes the header check.

    This patch changes the sg flag to a full features flag. The same method
    can be used to implement TSO ECN support. We simply have to mark packets
    with CWR set with SKB_GSO_ECN so that only hardware with a corresponding
    NETIF_F_TSO_ECN can accept them. The GSO engine can either fully segment
    the packet, or segment the first MTU and pass the rest to the hardware for
    further segmentation.

  • 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.

  • 14c850212   [INET_SOCK]: Move struct inet_sock & helper functions to net/inet_sock.h ... Browse Code »

    To help in reducing the number of include dependencies, several files were
    touched as they were getting needed headers indirectly for stuff they use.

    Thanks also to Alan Menegotto for pointing out that net/dccp/proto.c had
    linux/dccp.h include twice.

  • 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.

  • d83d8461f   [IP_SOCKGLUE]: Remove most of the tcp specific calls ... Browse Code »

    As DCCP needs to be called in the same spots.

    Now we have a member in inet_sock (is_icsk), set at sock creation time from
    struct inet_protosw->flags (if INET_PROTOSW_ICSK is set, like for TCP and
    DCCP) to see if a struct sock instance is a inet_connection_sock for places
    like the ones in ip_sockglue.c (v4 and v6) where we previously were looking if
    sk_type was SOCK_STREAM, that is insufficient because we now use the same code
    for DCCP, that has sk_type SOCK_DCCP.

  • 86c8f9d15   [IPV4] Fix EPROTONOSUPPORT error in inet_create ... Browse Code »

    There is a coding error in inet_create that causes it to always return
    ESOCKTNOSUPPORT. It should return EPROTONOSUPPORT when there are
    protocols registered for a given socket type but none of them match
    the requested protocol.

    This is based on a patch by Jayachandran C.
