This fixes the following sparse warnings: sparse: symbol 'tipc_update_nametbl' was not declared. Should it be static? Also, the function is changed to return bool upon success, rather than a potentially freed pointer. Signed-off-by:

Pablo Neira Ayuso says: ==================== nf-next pull request The following patchset contains Netfilter/IPVS updates for your net-next tree. Regarding nf_tables, most updates focus on consolidating the NAT infrastructure and adding support for masquerading. More specifically, they are: 1) use __u8 instead of u_int8_t in arptables header, from Mike Frysinger. 2) Add support to match by skb->pkttype to the meta expression, from Ana Rey. 3) Add support to match by cpu to the meta expression, also from Ana Rey. 4) A smatch warning about IPSET_ATTR_MARKMASK validation, patch from Vytas Dauksa. 5) Fix netnet and netportnet hash types the range support for IPv4, from Sergey Popovich. 6) Fix missing-field-initializer warnings resolved, from Mark Rustad. 7) Dan Carperter reported possible integer overflows in ipset, from Jozsef Kadlecsick. 8) Filter out accounting objects in nfacct by type, so you can selectively reset quotas, from Alexey Perevalov. 9) Move specific NAT IPv4 functions to the core so x_tables and nf_tables can share the same NAT IPv4 engine. 10) Use the new NAT IPv4 functions from nft_chain_nat_ipv4. 11) Move specific NAT IPv6 functions to the core so x_tables and nf_tables can share the same NAT IPv4 engine. 12) Use the new NAT IPv6 functions from nft_chain_nat_ipv6. 13) Refactor code to add nft_delrule(), which can be reused in the enhancement of the NFT_MSG_DELTABLE to remove a table and its content, from Arturo Borrero. 14) Add a helper function to unregister chain hooks, from Arturo Borrero. 15) A cleanup to rename to nft_delrule_by_chain for consistency with the new nft_*() functions, also from Arturo. 16) Add support to match devgroup to the meta expression, from Ana Rey. 17) Reduce stack usage for IPVS socket option, from Julian Anastasov. 18) Remove unnecessary textsearch state initialization in xt_string, from Bojan Prtvar. 19) Add several helper functions to nf_tables, more work to prepare the enhancement of NFT_MSG_DELTABLE, again from Arturo Borrero. 20) Enhance NFT_MSG_DELTABLE to delete a table and its content, from Arturo Borrero. 21) Support NAT flags in the nat expression to indicate the flavour, eg. random fully, from Arturo. 22) Add missing audit code to ebtables when replacing tables, from Nicolas Dichtel. 23) Generalize the IPv4 masquerading code to allow its re-use from nf_tables, from Arturo. 24) Generalize the IPv6 masquerading code, also from Arturo. 25) Add the new masq expression to support IPv4/IPv6 masquerading from nf_tables, also from Arturo. ==================== Signed-off-by: -

Tom Herbert says: ==================== net: enable GRO for IPIP and SIT This patch sets populates the IPIP and SIT offload structures with gro_receive and gro_complete functions. This enables use of GRO for these. Also, fixed a problem in IPv6 where we were not properly initializing flush_id. Peformance results are below. Note that these tests were done on bnx2x which doesn't provide RX checksum offload of IPIP or SIT (i.e. does not give CHEKCSUM_COMPLETE). Also, we don't get 4-tuple hash for RSS only 2-tuple in this case so all the packets between two hosts are winding up on the same queue. Net result is the interrupting CPU is the bottleneck in GRO (checksumming every packet there). Testing: netperf TCP_STREAM between two hosts using bnx2x. * Before fix IPIP 1 connection 6.53% CPU utilization 6544.71 Mbps 20 connections 13.79% CPU utilization 9284.54 Mbps SIT 1 connection 6.68% CPU utilization 5653.36 Mbps 20 connections 18.88% CPU utilization 9154.61 Mbps * After fix IPIP 1 connection 5.73% CPU utilization 9279.53 Mbps 20 connections 7.14% CPU utilization 7279.35 Mbps SIT 1 connection 2.95% CPU utilization 9143.36 Mbps 20 connections 7.09% CPU utilization 6255.3 Mbps ==================== Signed-off-by: -

Tom Herbert authored
In TCP gro we check flush_id which is derived from the IP identifier. In IPv4 gro path the flush_id is set with the expectation that every matched packet increments IP identifier. In IPv6, the flush_id is never set and thus is uinitialized. What's worse is that in IPv6 over IPv4 encapsulation, the IP identifier is taken from the outer header which is currently not incremented on every packet for Linux stack, so GRO in this case never matches packets (identifier is not increasing). This patch clears flush_id for every time for a matched packet in IPv6 gro_receive. We need to do this each time to overwrite the setting that would be done in IPv4 gro_receive per the outer header in IPv6 over Ipv4 encapsulation. Signed-off-by:

Nikolay Aleksandrov says: ==================== bonding: get rid of bond->lock This patch-set removes the last users of bond->lock and converts the places that needed it for sync to use curr_slave_lock or RCU as appropriate. I've run this with lockdep and have stress-tested it via loading/unloading and enslaving/releasing in parallel while outputting bond's proc, I didn't see any issues. Please pay special attention to the procfs change, I've done about an hour of stress-testing on it and have checked that the event that causes the bonding to delete its proc entry (NETDEV_UNREGISTER) is called before ndo_uninit() and the freeing of the dev so any readers will sync with that. Also ran sparse checks and there were no splats. v2: Add patch 0001/cxgb4 bond->lock removal, RTNL should be held in the notifier call, the other patches are the same. Also tested with allmodconfig to make sure there're no more users of bond->lock. Changes from the RFC: use RCU in procfs instead of RTNL since RTNL might lead to a deadlock with unloading and also is much slower. The bond destruction syncs with proc via the proc locks. There's one new patch that converts primary_slave to use RCU as it was necessary to fix a longstanding bugs in sysfs and procfs and to make it easy to migrate bond's procfs to RCU. And of course rebased on top of net-next current. This is the first patch-set in a series that should simplify the bond's locking requirements and will make it easier to define the locking conditions necessary for the various paths. The goal is to rely on RTNL and rcu alone, an extra lock would be needed in a few special cases that would be documented very well. ==================== Signed-off-by: -

The usage of bond->lock in bond_main.c was completely unnecessary as it didn't help to sync with anything, most of the spots already had RTNL. Since there're no more users of bond->lock, remove it. Signed-off-by:

We're safe to remove the bond->lock use from the arp targets because arp_rcv_probe no longer acquires bond->lock, only rcu_read_lock. Also setting the primary slave is safe because noone uses the bond->lock as a syncing mechanism for that anymore. Signed-off-by:

Use RCU to protect against slave release, the proc show function will sync with the bond destruction by the proc locks and the fact that the bond is released after NETDEV_UNREGISTER which causes the bonding to remove the proc entry. Signed-off-by:

In 3ad mode the only syncing needed by bond->lock is for the wq and the recv handler, so change them to use curr_slave_lock. There're no locking dependencies here as 3ad doesn't use curr_slave_lock at all. Signed-off-by:

RTNL should be already held in the notifier call so the slave list can be traversed without a problem, remove the unnecessary bond->lock. CC: Hariprasad S <hariprasad@chelsio.com> Signed-off-by:

Reported by Mikulas Patocka, kmemcheck currently barks out a false positive since we don't have special kmemcheck annotation for bitfields used in bpf_prog structure. We currently have jited:1, len:31 and thus when accessing len while CONFIG_KMEMCHECK enabled, kmemcheck throws a warning that we're reading uninitialized memory. As we don't need the whole bit universe for pages member, we can just split it to u16 and use a bool flag for jited instead of a bitfield. Signed-off-by:
