This popped some compiler errors due to mismatched prototypes.

[104661.923653] huh, entered softirq 3 NET_RX ffffffff81613740 preempt_count 00000101, exited with 00000102? Problem comes from commit 0e734419 (ipv4: Use inet_csk_route_child_sock() in DCCP and TCP.) If inet_csk_route_child_sock() returns NULL, we should release socket lock before freeing it. Another lock imbalance exists if __inet_inherit_port() returns an error since commit 093d2823 ( tproxy: fix hash locking issue when using port redirection in __inet_inherit_port()) a backport is also needed for >= 2.6.37 kernels.

the tcp and udp code creates a set of struct file_operations at runtime while it can also be done at compile time, with the added benefit of then having these file operations be const. the trickiest part was to get the "THIS_MODULE" reference right; the naive method of declaring a struct in the place of registration would not work for this reason.

Zheng Liang(lzheng@redhat.com) found a bug that if we config bonding with arp monitor, sometimes bonding driver cannot get the speed and duplex from its slaves, it will assume them to be 100Mb/sec and Full, please see /proc/net/bonding/bond0. But there is no such problem when uses miimon. (Take igb for example) I find that the reason is that after dev_open() in bond_enslave(), bond_update_speed_duplex() will call igb_get_settings() , but in that function, it runs ethtool_cmd_speed_set(ecmd, -1); ecmd->duplex = -1; because igb get an error value of status. So even dev_open() is called, but the device is not really ready to get its settings. Maybe it is safe for us to call igb_get_settings() only after this message shows up, that is "igb: p4p1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX". So I prefer to update the speed and duplex for a slave when reseices NETDEV_CHANGE/NETDEV_UP event. Changelog V2: 1 remove the "fake 100/Full" logic in bond_update_speed_duplex(), set speed and duplex to -1 when it gets error value of speed and duplex. 2 delete the warning in bond_enslave() if bond_update_speed_duplex() returns error. 3 make bond_info_show_slave() handle bad values of speed and duplex.

When (de)configuring a vlan interface, the IFF_ALLMULTI ans IFF_PROMISC flags are cleared or set on the underlying interface. So, if these flags are changed on a vlan interface that is not up, the flags underlying interface might be set or cleared twice. Only propagating flag changes when a device is up makes sure this does not happen. It also makes sure that an underlying device is not set to promiscuous or allmulti mode for a vlan device that is down. Signed-off-by:

commit f1585086 (netfilter: nfnetlink_queue: return error number to caller) erronously assigns the return value of nf_queue() to the "ret" value. This can cause bogus return values if we encounter QUEUE verdict when bypassing is enabled, the listener does not exist and the next hook returns NF_STOLEN. In this case nf_hook_slow returned -ESRCH instead of 0. Signed-off-by:

Several callers (h323 conntrack, xt_addrtype) assume that the returned **dst only needs to be released if the function returns 0. This is true for the ipv4 implementation, but not for the ipv6 one.

This patch exports several definitions that used to live under include/net/netfilter/nf_nat.h. These definitions, although not exported, have been used by iptables and other userspace applications like miniupnpd since long time. Basically, these userspace tools included some internal definition of the required structures and they assume no changes in the binary representation (which is OK indeed). To resolve this situation, this patch makes public the required structure and install them in INSTALL_HDR_PATH. See: https://bugs.gentoo.org/376873, for more information. This patch is heavily based on the initial patch sent by: Anthony G. Basile <blueness@gentoo.org> Which was entitled: netfilter: export sanitized nf_nat.h to INSTALL_HDR_PATH Signed-off-by:

epoll can acquire recursively acquire ep->mtx on multiple "struct eventpoll"s at once in the case where one epoll fd is monitoring another epoll fd. This is perfectly OK, since we're careful about the lock ordering, but it causes spurious lockdep warnings. Annotate the recursion using mutex_lock_nested, and add a comment explaining the nesting rules for good measure. Recent versions of systemd are triggering this, and it can also be demonstrated with the following trivial test program: --------------------8<-------------------- int main(void) { int e1, e2; struct epoll_event evt = { .events = EPOLLIN }; e1 = epoll_create1(0); e2 = epoll_create1(0); epoll_ctl(e1, EPOLL_CTL_ADD, e2, &evt); return 0; } --------------------8<-------------------- Reported-by:Nelson Elhage <nelhage@nelhage.com> Acked-by:
