2015-10-12ipv4: Pass struct net into ip_defrag and ip_check_defragEric W. Biederman1-1/+1
The function ip_defrag is called on both the input and the output paths of the networking stack. In particular conntrack when it is tracking outbound packets from the local machine calls ip_defrag. So add a struct net parameter and stop making ip_defrag guess which network namespace it needs to defragment packets in. Signed-off-by: "Eric W.

2015-10-09net/nfnetlink: lockdep_nfnl_is_held can be booleanYaowei Bai1-1/+1
This patch makes lockdep_nfnl_is_held return bool to improve readability due to this particular function only using either one or zero as its return value. No functional change. Signed-off-by: Yaowei Bai <bywxiaobai@163.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-10-08ipv4: Merge ip_local_out and ip_local_out_skEric W. Biederman1-1/+1

2015-10-05nfnetlink: use y2038 safe timestampArnd Bergmann1-3/+3
The __build_packet_message function fills a nfulnl_msg_packet_timestamp structure that uses 64-bit seconds and is therefore y2038 safe, but it uses an intermediate 'struct timespec' which is not. This trivially changes the code to use 'struct timespec64' instead, to correct the result on 32-bit architectures.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following pull request contains Netfilter/IPVS updates for net-next containing 90 patches from Eric Biederman. The main goal of this batch is to avoid recurrent lookups for the netns pointer, that happens over and over again in our Netfilter/IPVS code. The idea consists of passing netns pointer from the hook state to the relevant functions and objects where this may be needed. You can find more information on the IPVS updates from Simon Horman's commit merge message: c3456026adc0 ("Merge tag 'ipvs2-for-v4.4' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/ipvs-next"). Exceptionally, this time, I'm not posting the patches again on netdev, Eric already Cc'ed this mailing list in the original submission. If you need me to make, just let me know. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
