After removing the tupleid register which changed per tuple, tuple modify headers set the ct_state, zone, mark, and label registers. For non-natted tuples going through the same tc rules path, their values will be the same, and all their modify headers will be the same. Re-use tuple modify header when possible, by adding each new modify header to an hahstable, and looking up identical ones before creating a new one. Signed-off-by:

Remove tupleid, and replace it with zone_restore, which is the zone an established tuple sets after match. On miss, Use this zone + tuple taken from the skb, to lookup the ct entry and restore it. This improves flow insertion rate by avoiding the allocation of a header rewrite context. Signed-off-by:

Next patches will remove the tupleid registers that is used to restore the ct state on miss, and instead use the tuple on the missed packet to lookup which state to restore. Disable tuple rewrites after connection tracking. For tuple rewrites, inject a ct_state=-trk match so it won't change the tuple for established flows (+trk) that passed connection tracking, and instead miss to software. Signed-off-by:

Ido Schimmel says: ==================== Expose port split attributes Danielle says: Currently, user space has no way of knowing if a port can be split and into how many ports. Among other things, this makes it impossible to write generic tests for port split functionality. Therefore, this set exposes two new devlink port attributes to user space: Number of lanes and whether the port can be split or not. Patch set overview: Patches #1-#4 cleanup 'struct devlink_port_attrs' and reduce the number of parameters passed between drivers and devlink via devlink_port_attrs_set() Patch #5 adds devlink port lanes attributes Patches #6-#7 add devlink port splittable attribute Patch #8 exploits the fact that devlink is now aware of port's number of lanes and whether the port can be split or not and moves some checks from drivers to devlink Patch #9 adds a port split test Changes since v2: * Remove some local variables from patch #3 * Reword function description in patch #5 * Fix a bug in patch #8 * Add a test for the splittable attribute in patch #9 Changes since v1: * Rename 'width' attribute to 'lanes' * Add 'splittable' attribute * Move checks from drivers to devlink ==================== Reviewed-by:

After commit bf976514 ("sock: Make sk_protocol a 16-bit value") the current size of 'sdiag_protocol' is not sufficient to represent the possible protocol values. This change introduces a new inet diag request attribute to let user space specify the relevant protocol number using u32 values. The attribute is parsed by inet diag core on get/dump command and the extended protocol value, if available, is preferred to 'sdiag_protocol' to lookup the diag handler. The parse attributed are exposed to all the diag handlers via the cb->data. Note that inet_diag_dump_one_icsk() is left unmodified, as it will not be used by protocol using the extended attribute.

It's possible that device removal happens when the bond is in non-AB mode, and addition happens in AB mode, so bond_ipsec_del_sa() never gets called, which leaves security associations in an odd state if bond_ipsec_add_sa() then gets called after switching the bond into AB. Just call add and delete universally for all modes to keep things consistent. However, it's also possible that this code gets called when the system is shutting down, and the xfrm subsystem has already been disconnected from the bond device, so we need to do some error-checking and bail, lest we hit a null ptr deref.

Linus Walleij says: ==================== RTL8366RB tagging support This patch set adds DSA tagging support to the RTL8366RB DSA driver.

This activates the support to use the CPU tag to properly direct ingress traffic to the right port. Bit 15 in register RTL8368RB_CPU_CTRL_REG can be set to 1 to disable the insertion of the CPU tag which is what the code currently does. The bit 15 define calls this setting RTL8368RB_CPU_INSTAG which is confusing since the inverse meaning is implied: programmers may think that setting this bit to 1 will *enable* inserting the tag rather than disabling it, so rename this setting in bit 15 to RTL8368RB_CPU_NO_TAG which is more to the point. After this e.g. ping works out-of-the-box with the RTL8366RB. Cc: DENG Qingfang <dqfext@gmail.com> Cc: Mauri Sandberg <sandberg@mailfence.com> Reviewed-by:

This implements the known parts of the Realtek 4 byte tag protocol version 0xA, as found in the RTL8366RB DSA switch. It is designated as protocol version 0xA as a different Realtek 4 byte tag format with protocol version 0x9 is known to exist in the Realtek RTL8306 chips. The tag and switch chip lacks public documentation, so the tag format has been reverse-engineered from packet dumps. As only ingress traffic has been available for analysis an egress tag has not been possible to develop (even using educated guesses about bit fields) so this is as far as it gets. It is not known if the switch even supports egress tagging. Excessive attempts to figure out the egress tag format was made. When nothing else worked, I just tried all bit combinations with 0xannp where a is protocol and p is port. I looped through all values several times trying to get a response from ping, without any positive result. Using just these ingress tags however, the switch functionality is vastly improved and the packets find their way into the destination port without any tricky VLAN configuration. On the D-Link DIR-685 the LAN ports now come up and respond to ping without any command line configuration so this is a real improvement for users. Egress packets need to be restricted to the proper target ports using VLAN, which the RTL8366RB DSA switch driver already sets up.

The hardware VLAN offload feature on our NIC does not have separate knobs for handling customer and service tags on RX. Either offloading of both must be enabled or both must be disabled. Introduce definitions for the combined feature set in order to clean up the code and make this constraint more clear. Technically these features can be separately enabled on TX, however, since the default is to turn both on, the combined TX feature set is also introduced for code consistency. Signed-off-by:
