Stateful network admission policy may allow connections to one direction and reject connections initiated in the other direction. 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. Signed-off-by:

Add the fields of the conntrack original direction 5-tuple to struct sw_flow_key. The new fields are initially marked as non-existent, and are populated whenever a conntrack action is executed and either finds or generates a conntrack entry. This means that these fields exist for all packets that were not rejected by conntrack as untrackable. The original tuple fields in the sw_flow_key are filled from the original direction tuple of the conntrack entry relating to the current packet, or from the original direction tuple of the master conntrack entry, if the current conntrack entry has a master. Generally, expected connections of connections having an assigned helper (e.g., FTP), have a master conntrack entry. The main purpose of the new conntrack original tuple fields is to allow matching on them for policy decision purposes, with the premise that the admissibility of tracked connections reply packets (as well as original direction packets), and both direction packets of any related connections may be based on ACL rules applying to the master connection's original direction 5-tuple. This also makes it easier to make policy decisions when the actual packet headers might have been transformed by NAT, as the original direction 5-tuple represents the packet headers before any such transformation. When using the original direction 5-tuple the admissibility of return and/or related packets need not be based on the mere existence of a conntrack entry, allowing separation of admission policy from the established conntrack state. While existence of a conntrack entry is required for admission of the return or related packets, policy changes can render connections that were initially admitted to be rejected or dropped afterwards. If the admission of the return and related packets was based on mere conntrack state (e.g., connection being in an established state), a policy change that would make the connection rejected or dropped would need to find and delete all conntrack entries affected by such a change. When using the original direction 5-tuple matching the affected conntrack entries can be allowed to time out instead, as the established state of the connection would not need to be the basis for packet admission any more. It should be noted that the directionality of related connections may be the same or different than that of the master connection, and neither the original direction 5-tuple nor the conntrack state bits carry this information. If needed, the directionality of the master connection can be stored in master's conntrack mark or labels, which are automatically inherited by the expected related connections. The fact that neither ARP nor ND packets are trackable by conntrack allows mutual exclusion between ARP/ND and the new conntrack original tuple fields. Hence, the IP addresses are overlaid in union with ARP and ND fields. This allows the sw_flow_key to not grow much due to this patch, but it also means that we must be careful to never use the new key fields with ARP or ND packets. ARP is easy to distinguish and keep mutually exclusive based on the ethernet type, but ND being an ICMPv6 protocol requires a bit more attention. Signed-off-by:

We avoid calling into nf_conntrack_in() for expected connections, as that would remove the expectation that we want to stick around until we are ready to commit the connection. Instead, we do a lookup in the expectation table directly. However, after a successful expectation lookup we have set the flow key label field from the master connection, whereas nf_conntrack_in() does not do this. This leads to master's labels being inherited after an expectation lookup, but those labels not being inherited after the corresponding conntrack action with a commit flag. This patch resolves the problem by changing the commit code path to also inherit the master's labels to the expected connection. Resolving this conflict in favor of inheriting the labels allows more information be passed from the master connection to related connections, which would otherwise be much harder if the 32 bits in the connmark are not enough. Labels can still be set explicitly, so this change only affects the default values of the labels in presense of a master connection.

Since 23014011 ("netfilter: conntrack: support a fixed size of 128 distinct labels"), the size of conntrack labels extension has fixed to 128 bits, so we do not need to check for labels sizes shorter than 128 at run-time. This patch simplifies labels length logic accordingly, but allows the conntrack labels size to be increased in the future without breaking the build. In the event of conntrack labels increasing in size OVS would still be able to deal with the 128 first label bits. Suggested-by:

The conntrack lookup for existing connections fails to invert the packet 5-tuple for NATted packets, and therefore fails to find the existing conntrack entry. Conntrack only stores 5-tuples for incoming packets, and there are various situations where a lookup on a packet that has already been transformed by NAT needs to be made. Looking up an existing conntrack entry upon executing packet received from the userspace is one of them. This patch fixes ovs_ct_find_existing() to invert the packet 5-tuple for the conntrack lookup whenever the packet has already been transformed by conntrack from its input form as evidenced by one of the NAT flags being set in the conntrack state metadata.

If the ena driver detects that the device is not behave as expected, it tries to reset the device. The reset flow calls ena_down, which will frees all the resources the driver allocates and then it will reset the device. This flow can cause memory corruption if the device is still writes to the driver's memory space. To overcome this potential race, move the reset before the device resources are freed. Signed-off-by:

Xin Long says: ==================== sctp: add sender-side procedures for stream reconf asoc reset and add streams Patch 4/6 is to implement sender-side procedures for the SSN/TSN Reset Request Parameter described in rfc6525 section 5.1.4, patch 3/6 is ahead of it to define a function to make the request chunk for it. Patch 6/6 is to implement sender-side procedures for the Add Incoming and Outgoing Streams Request Parameter Request Parameter described in rfc6525 section 5.1.5 and 5.1.6, patch 5/6 is ahead of it to define a function to make the request chunk for it. Patch 2/6 is a fix to recover streams states when it fails to send request and Patch 1/6 is to drop some unncessary __packed from some old structures. v1->v2: - put these into a smaller group. - rename some temporary variables in the codes. - rename the titles of the commits and improve some changelogs. v2->v3: - re-split the patchset and make sure it has no dead codes for review. - move some codes into stream.c from socket.c. v3->v4: - add one more patch to fix a send reset stream request issue. - doing actual work only when request is sent successfully. - reduce some indents in sctp_send_add_streams. v4->v5: - close streams before sending request and recover them when sending fails in patch 1/5 and patch 3/5 v5->v6: - add patch 1/6 to drop some unncessary __packed from some old structures. - remove __packed from some new structures in patch 3/6 and 5/6. - define unsigned int outcnt and incnt to make codes smaller in patch 6/6. - use krealloc instead of kcalloc and remove ksize check in patch 6/6, as ksize check is acutally used in krealloc already. ==================== Signed-off-by:

This patch is to define Add Incoming/Outgoing Streams Request Parameter described in rfc6525 section 4.5 and 4.6. They can be in one same chunk trunk as rfc6525 section 3.1-7 describes, so make them in one function. Signed-off-by:
