0b6280c6 · Linus Torvalds <[email protected]> · 2015-05-22 15:44:50 -07:00

Pull networking fixes from David Miller:

 1) Don't leak ipvs->sysctl_tbl, from Tommi Rentala.

 2) Fix neighbour table entry leak in rocker driver, from Ying Xue.

 3) Do not emit bonding notifications for unregistered interfaces, from
    Nicolas Dichtel.

 4) Set ipv6 flow label properly when in TIME_WAIT state, from Florent
    Fourcot.

 5) Fix regression in ipv6 multicast filter test, from Henning Rogge.

 6) do_replace() in various footables netfilter modules is missing a
    check for 0 counters in the datastructure provided by the user.  Fix
    from Dave Jones, and found with trinity.

 7) Fix RCU bug in packet scheduler classifier module unloads, from
    Daniel Borkmann.

 8) Avoid deadlock in tcp_get_info() by using u64_sync.  From Eric
    Dumzaet.

 9) Input packet processing can race with inetdev_destroy() teardown,
    fix potential OOPS in ip_error() by explicitly testing whether the
    inetdev is still attached.  From Eric W Biederman.

10) MLDv2 parser in bridge multicast code breaks too early while
    parsing.  Fix from Thadeu Lima de Souza Cascardo.

11) Asking for settings on non-zero PHYID doesn't work because we do not
    import the command structure from the user and use the PHYID
    provided there.  Fix from Arun Parameswaran.

12) Fix UDP checksums with IPV6 RAW sockets, from Vlad Yasevich.

13) Missing NF_TABLES depends for TPROXY etc can cause build failures,
    fix from Florian Westphal.

14) Fix netfilter conntrack to handle RFC5961 challenge ACKs properly,
    from Jesper Dangaard Brouer.

15) If netlink autobind retry fails, we have to reset the sockets portid
    back to zero.  From Herbert Xu.

16) VXLAN netns exit code unregisters using wrong device, from John W
    Linville.

17) Add some USB device IDs to ath3k and btusb bluetooth drivers, from
    Dmitry Tunin and Wen-chien Jesse Sung.
