  • b903d324b   ipv6: tcp: fix TCLASS value in ACK messages sent from TIME_WAIT ... Browse Code »

    commit 66b13d99d96a (ipv4: tcp: fix TOS value in ACK messages sent from
    TIME_WAIT) fixed IPv4 only.

    This part is for the IPv6 side, adding a tclass param to ip6_xmit()

    We alias tw_tclass and tw_tos, if socket family is INET6.

    [ if sockets is ipv4-mapped, only IP_TOS socket option is used to fill
    TOS field, TCLASS is not taken into account ]

  • 9f7d653b6   sctp: Add Auto-ASCONF support (core). ... Browse Code »

    SCTP reconfigure the IP addresses in the association by using
    ASCONF chunks as mentioned in RFC5061. For example, we can
    start to use the newly configured IP address in the existing
    association. This patch implements automatic ASCONF operation
    in the SCTP stack with address events in the host computer,
    which is called auto_asconf.

    The ipv6 routing lookup does give us a source address,
    but instead of filling it into the dst, it's stored in
    the flowi. We can use that instead of going through the
    entire source address selection again.
    Also the useless ->dst_saddr member of sctp_pf is removed.

    sctp_v6_to_addr(), which can be reused to cleanup some dup

  • 625034113   sctp: fix sctp to work with ipv6 source address routing ... Browse Code »

    In the below test case, using the source address routing,
    sctp can not work.
    Node-A
    1)ifconfig eth0 inet6 add 2001:1::1/64
    2)ip -6 rule add from 2001:1::1 table 100 pref 100
    3)ip -6 route add 2001:2::1 dev eth0 table 100
    4)sctp_darn -H 2001:1::1 -P 250 -l &
    Node-B
    1)ifconfig eth0 inet6 add 2001:2::1/64
    2)ip -6 rule add from 2001:2::1 table 100 pref 100
    3)ip -6 route add 2001:1::1 dev eth0 table 100
    4)sctp_darn -H 2001:2::1 -P 250 -h 2001:1::1 -p 250 -s

    root cause:
    Node-A and Node-B use the source address routing, and
    at begining, source address will be NULL,sctp will
    search the routing table by the destination address,
    because using the source address routing table, and
    the result dst_entry will be NULL.

    solution:
    walk through the bind address list to get the source
    address and then lookup the routing table again to get
    the correct dst_entry.

  • 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.

  • 914e1c8b6   sctp: Inherit all socket options from parent correctly. ... Browse Code »

    During peeloff/accept() sctp needs to save the parent socket state
    into the new socket so that any options set on the parent are
    inherited by the child socket. This was found when the
    parent/listener socket issues SO_BINDTODEVICE, but the
    data was misrouted after a route cache flush.

  • 52cae8f06   sctp: try harder to figure out address family when checking wildcards ... Browse Code »

    sctp_is_any() function that is used to check for wildcard addresses
    only looks at the address itself to determine the address family.
    This function is used in the API to check the address passed in from
    the user. If the user simply zerroes out the sockaddr_storage and
    pass that in, we'll end up failing. So, let's try harder to determine
    the address family by also checking the socket if it's possible.

  • f880374c2   sctp: Drop ipfargok in sctp_xmit function ... Browse Code »

    The ipfragok flag controls whether the packet may be fragmented
    either on the local host on beyond. The latter is only valid on
    IPv4.

    In fact, we never want to do the latter even on IPv4 when PMTU is
    enabled. This is because even though we can't fragment packets
    within SCTP due to the prtocol's inherent faults, we can still
    fragment it at IP layer. By setting the DF bit we will improve
    the PMTU process.

    RFC 2960 only says that we SHOULD clear the DF bit in this case,
    so we're compliant even if we set the DF bit. In fact RFC 4960
    no longer has this statement.

    Once we make this change, we only need to control the local
    fragmentation. There is already a bit in the skb which controls
    that, local_df. So this patch sets that instead of using the
    ipfragok argument.

    The only complication is that there isn't a struct sock object
    per transport, so for IPv4 we have to resort to changing the
    pmtudisc field for every packet. This should be safe though
    as the protocol is single-threaded.

    Note that after this patch we can remove ipfragok from the rest
    of the stack too.

    was never set. This patch brings back the markings for IPv6 traffic.
