v2: Move struct switchdev_obj automatics to inner scope where there used. v1: To maintain backward compatibility with the existing iproute2 "bridge vlan" command, let bridge's setlink/dellink handler call into either the port driver's 8021q ndo ops or the port driver's bridge_setlink/dellink ops. This allows port driver to choose 8021q ops or the newer bridge_setlink/dellink ops when implementing VLAN add/del filtering on the device. The iproute "bridge vlan" command does not need to be modified. To summarize using the "bridge vlan" command examples, we have: 1) bridge vlan add|del vid VID dev DEV Here iproute2 sets MASTER flag. Bridge's bridge_setlink/dellink is called. Vlan is set on bridge for port. If port driver implements ndo 8021q ops, call those to port driver can install vlan filter on device. Otherwise, if port driver implements bridge_setlink/dellink ops, call those to install vlan filter to device. This option only works if port is bridged. 2) bridge vlan add|del vid VID dev DEV master Same as 1) 3) bridge vlan add|del vid VID dev DEV self Bridge's bridge_setlink/dellink isn't called. Port driver's bridge_setlink/dellink is called, if implemented. This option works if port is bridged or not. If port is not bridged, a VLAN can still be added/deleted to device filter using this variant. 4) bridge vlan add|del vid VID dev DEV master self This is a combination of 1) and 3), but will only work if port is bridged.

bpf_trace_printk() is a helper function used to debug eBPF programs. Let socket and TC programs use it as well. Note, it's DEBUG ONLY helper.

eBPF programs attached to kprobes need to filter based on current->pid, uid and other fields, so introduce helper functions: u64 bpf_get_current_pid_tgid(void) Return: current->tgid << 32 | current->pid u64 bpf_get_current_uid_gid(void) Return: current_gid << 32 | current_uid bpf_get_current_comm(char *buf, int size_of_buf) stores current->comm into buf They can be used from the programs attached to TC as well to classify packets based on current task fields. Update tracex2 example to print histogram of write syscalls for each process instead of aggregated for all. Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next This a bit large (and late) patchset that contains Netfilter updates for net-next. Most relevantly br_netfilter fixes, ipset RCU support, removal of x_tables percpu ruleset copy and rework of the nf_tables netdev support. More specifically, they are: 1) Warn the user when there is a better protocol conntracker available, from Marcelo Ricardo Leitner. 2) Fix forwarding of IPv6 fragmented traffic in br_netfilter, from Bernhard Thaler. This comes with several patches to prepare the change in first place. 3) Get rid of special mtu handling of PPPoE/VLAN frames for br_netfilter. This is not needed anymore since now we use the largest fragment size to refragment, from Florian Westphal. 4) Restore vlan tag when refragmenting in br_netfilter, also from Florian. 5) Get rid of the percpu ruleset copy in x_tables, from Florian. Plus another follow up patch to refine it from Eric Dumazet. 6) Several ipset cleanups, fixes and finally RCU support, from Jozsef Kadlecsik. 7) Get rid of parens in Netfilter Kconfig files. 8) Attach the net_device to the basechain as opposed to the initial per table approach in the nf_tables netdev family. 9) Subscribe to netdev events to detect the removal and registration of a device that is referenced by a basechain. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

In case the net_device is gone, we have to unregister the hooks and put back the reference on the net_device object. Once it comes back, register them again. This also covers the device rename case. This patch also adds a new flag to indicate that the basechain is disabled, so their hooks are not registered. This flag is used by the netdev family to handle the case where the net_device object is gone. Currently this flag is not exposed to userspace. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

Pablo Neira Ayuso authored
The device is part of the hook configuration, so instead of a global configuration per table, set it to each of the basechain that we create. This patch reworks ebddf1a8 ("netfilter: nf_tables: allow to bind table to net_device"). Note that this adds a dev_name field in the nft_base_chain structure which is required the netdev notification subscription that follows up in a patch to handle gone net_devices.

After Florian patches, there is no need for XT_TABLE_INFO_SZ anymore : Only one copy of table is kept, instead of one copy per cpu. We also can avoid a dereference if we put table data right after xt_table_info. It reduces register pressure and helps compiler. Then, we attempt a kmalloc() if total size is under order-3 allocation, to reduce TLB pressure, as in many cases, rules fit in 32 KB.

First comes the small changes, then the bugfixes and at the end the RCU related patches. * Use MSEC_PER_SEC consistently instead of the number. * Use SET_WITH_*() helpers to test set extensions from Sergey Popovich. * Check extensions attributes before getting extensions from Sergey Popovich. * Permit CIDR equal to the host address CIDR in IPv6 from Sergey Popovich. * Make sure we always return line number on batch in the case of error from Sergey Popovich. * Check CIDR value only when attribute is given from Sergey Popovich. * Fix cidr handling for hash:*net* types, reported by Jonathan Johnson. * Fix parallel resizing and listing of the same set so that the original set is kept for the whole dumping. * Make sure listing doesn't grab a set which is just being destroyed. * Remove rbtree from ip_set_hash_netiface.c in order to introduce RCU. * Replace rwlock_t with spinlock_t in "struct ip_set", change the locking in the core and simplifications in the timeout routines. * Introduce RCU locking in bitmap:* types with a slight modification in the logic on how an element is added. * Introduce RCU locking in hash:* types. This is the most complex part of the changes. * Introduce RCU locking in list type where standard rculist is used. * Fix coding styles reported by checkpatch.pl. ==================== Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

Standard rculist is used. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>

Jozsef Kadlecsik authored
Three types of data need to be protected in the case of the hash types: a. The hash buckets: standard rcu pointer operations are used. b. The element blobs in the hash buckets are stored in an array and a bitmap is used for book-keeping to tell which elements in the array are used or free. c. Networks per cidr values and the cidr values themselves are stored in fix sized arrays and need no protection. The values are modified in such an order that in the worst case an element testing is repeated once with the same cidr value. The ipset hash approach uses arrays instead of lists and therefore is incompatible with rhashtable.

There's nothing much required because the bitmap types use atomic bit operations. However the logic of adding elements slightly changed: first the MAC address updated (which is not atomic), then the element activated (added). The extensions may call kfree_rcu() therefore we call rcu_barrier() at module removal. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>

When elements added to a hash:* type of set and resizing triggered, parallel listing could start to list the original set (before resizing) and "continue" with listing the new set. Fix it by references and using the original hash table for listing. Therefore the destroying of the original hash table may happen from the resizing or listing functions.

Initialize cidr array in element structure on element structure declaration to let more freedom to the compiler to optimize initialization right before element structure is used.

Currently, we can ask to authenticate DATA chunks and we can send DATA chunks on the same packet as COOKIE_ECHO, but if you try to combine both, the DATA chunk will be sent unauthenticated and peer won't accept it, leading to a communication failure. This happens because even though the data was queued after it was requested to authenticate DATA chunks, it was also queued before we could know that remote peer can handle authenticating, so sctp_auth_send_cid() returns false. The fix is whenever we set up an active key, re-check send queue for chunks that now should be authenticated. As a result, such packet will now contain COOKIE_ECHO + AUTH + DATA chunks, in that order.
