trafgen: minor fix to help text for option "--no-sock-mem"

Pushed last commit a bit too fast. The help text described that the single letter option for "--no-sock-mem" were "-m", which is wrong the right option is "-A" (only help txt, correct in the code and manual). Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com>

For example, to forward any TCP packet and decrease its TTL: $ tc filter add dev enp0s9 protocol ip parent ffff: \ flower ip_proto tcp \ action pedit munge ip ttl add 0xff pipe \ action mirred egress redirect dev veth0 In the example above, adding 0xff to this u8 field is actually decreasing it by one, since the operation is masked.

Miller <davem@davemloft.net> 2017-02-10net/act_pedit: Support using offset relative to the conventional network headersAmir Vadai1-16/+180 Extend pedit to enable the user setting offset relative to network headers. This change would enable to work with more complex header schemes (vs the simple IPv4 case) where setting a fixed offset relative to the network header is not enough. After this patch, the action has information about the exact header type and field inside this header. This information could be used later on for hardware offloading of pedit. Backward compatibility was being kept: 1. Old kernel <-> new userspace 2. New kernel <-> old userspace 3. add rule using new userspace <-> dump using old userspace 4. add rule using old userspace <-> dump using new userspace When using the extended api, new netlink attributes are being used. This way, operation will fail in (1) and (3) - and no malformed rule be added or dumped. Of course, new user space that doesn't need the new functionality can use the old netlink attributes and operation will succeed. Since action can support both api's, (2) should work, and it is easy to write the new user space to have (4) work. The action is having a strict check that only header types and commands it can handle are accepted. This way future additions will be much easier. Usage example: $ tc filter add dev enp0s9 protocol ip parent ffff: \ flower \ ip_proto tcp \ dst_port 80 \ action pedit munge tcp dport set 8080 pipe \ action mirred egress redirect dev veth0 Will forward tcp port whose original dest port is 80, while modifying the destination port to 8080.

Miller <davem@davemloft.net> 2017-02-10ipv4: fib: Add events for FIB replace and appendIdo Schimmel1-13/+14 The FIB notification chain currently uses the NLM_F_{REPLACE,APPEND} flags to signal routes being replaced or appended. Instead of using netlink flags for in-kernel notifications we can simply introduce two new events in the FIB notification chain. This has the added advantage of making the API cleaner, thereby making it clear that these events should be supported by listeners of the notification chain.

Miller <davem@davemloft.net> 2017-02-10ipv4: fib: Send notification before deleting FIB aliasIdo Schimmel1-7/+7 When a FIB alias is replaced following NLM_F_REPLACE, the ENTRY_ADD notification is sent after the reference on the previous FIB info was dropped. This is problematic as potential listeners might need to access it in their notification blocks. Solve this by sending the notification prior to the deletion of the replaced FIB alias. This is consistent with ENTRY_DEL notifications.

This is problematic for listeners of the FIB notification chain, as several FIB aliases can exist with matching parameters, but the type. Solve this by passing the actual type of the removed FIB alias.

This can lead to FIB_ENTRY_DEL notifications sent with the wrong table ID. The above doesn't affect current listeners, as the table ID is ignored during entry deletion, but this will change later in the patchset. When flushing a particular table, skip any aliases belonging to a different one.

After policy change it is possible that for a new connection an overlapping conntrack entry already exists, where the original direction of the existing connection is opposed to the new connection's initial packet. Most importantly, conntrack state relating to the current packet gets the "reply" designation based on whether the original direction tuple or the reply direction tuple matched. If this "directionality" is wrong w.r.t. to the stateful network admission policy it may happen that packets in neither direction are correctly admitted. This patch adds a new "force commit" option to the OVS conntrack action that checks the original direction of an existing conntrack entry. If that direction is opposed to the current packet, the existing conntrack entry is deleted and a new one is subsequently created in the correct direction.
