In an effort to make the PS3 gelic driver easier to maintain, create two new structures, struct gelic_hw_regs and struct gelic_chain_link, and replace the corresponding members of struct gelic_descr with the new structures. The new struct gelic_hw_regs holds the register variables used by the gelic hardware device. The new struct gelic_chain_link holds variables used to manage the driver's linked list of gelic descr structures. Signed-off-by:

Michael Chan says: ==================== bnxt_en: Add basic ntuple filter support The current driver only supports ntuple filters added by aRFS. This patch series adds basic support for user defined TCP/UDP ntuple filters added by the user using ethtool. Many of the patches are refactoring patches to make the existing code more general to support both aRFS and user defined filters. aRFS filters always have the Toeplitz hash value from the NIC. A Toepliz hash function is added in patch 5 to get the same hash value for user defined filters. The hash is used to store all ntuple filters in the table and all filters must be hashed identically using the same function and key. v2: Fix compile error in patch #4 when CONFIG_BNXT_SRIOV is disabled. ==================== Signed-off-by: -

Add support for adding user defined ntuple TCP/UDP filters. These filters are similar to aRFS filters except that they don't get aged. Source IP, destination IP, source port, or destination port can be unspecifed as wildcard. At least one of these tuples must be specifed. If a tuple is specified, the full mask must be specified. All ntuple related ethtool functions are now no longer compiled only for CONFIG_RFS_ACCEL. Reviewed-by:

Michael Chan authored
aRFS filters match all 5 tuples. User defined ntuple filters may specify some of the tuples as wildcards. To support that, we add the ntuple_flags to the bnxt_ntuple_filter struct to specify which tuple fields are to be matched. The matching tuple fields will then be passed to the firmware in bnxt_hwrm_cfa_ntuple_filter_alloc() to create the proper filter. Reviewed-by:

Refactor the logic into a new function bnxt_del_ntp_filters(). The same call will be used when the user deletes an ntuple filter. The bnxt_hwrm_cfa_ntuple_filter_free() function to call fw to free the ntuple filter is exported so that the ethtool logic can call it. Reviewed-by:

Generalize the ethtool logic that walks the ntuple hash table now that we have the common bnxt_filter_base structure. This will allow the code to easily extend to cover user defined ntuple or ether filters. Reviewed-by:

Add a new function bnxt_insert_ntp_filter() to insert the ntuple filter into the hash table and other basic setup. We'll use this function to insert a user defined filter from ethtool. Also, export bnxt_lookup_ntp_filter_from_idx() and bnxt_get_ntp_filter_idx() for similar purposes. All ntuple related functions are now no longer compiled only for CONFIG_RFS_ACCEL Reviewed-by:

Change the unused flag to BNXT_FLTR_INSERTED. To prepare for multiple pathways that an ntuple filter can be deleted, we add this flag. These filter structures can be retreived from the RCU hash table but only the caller that sees that the BNXT_FLTR_INSERTED flag is set can delete the filter structure and clear the flag under spinlock.

Add the helper function to look up the ntuple filter from the hash index and use it in bnxt_rx_flow_steer(). The helper function will also be used by user defined ntuple filters in the next patches. Reviewed-by:

Pavan Chebbi authored
For ntuple filters added by aRFS, the Toeplitz hash calculated by our NIC is available and is used to store the ntuple filter for quick retrieval. In the next patches, user defined ntuple filter support will be added and we need to calculate the same hash for these filters. The same hash function needs to be used so we can detect duplicates. Add the function bnxt_toeplitz() to calculate the Toeplitz hash for user defined ntuple filters. bnxt_toeplitz() uses the same Toeplitz key and the same key length as the NIC. bnxt_get_ntp_filter_idx() is added to return the hash index. For aRFS, the hash comes from the NIC. For user defined ntuple, we call bnxt_toeplitz() to calculate the hash index. Reviewed-by:

Refactor the L2 filter alloc/free logic so that these filters can be added/deleted by the user. The bp->ntp_fltr_bmap allocated size is also increased to allow enough IDs for L2 filters. Reviewed-by:

Michael Chan authored
With the new bnxt_l2_filter structure, we can now re-structure the bnxt_ntuple_filter structure to point to the bnxt_l2_filter structure. We eliminate the L2 ether address info from the ntuple filter structure as we can get the information from the L2 filter structure. Note that the source L2 MAC address is no longer used. Reviewed-by:
-
Michael Chan authored
The current driver only has an array of 4 additional L2 unicast addresses to support the netdev uc address list. Generalize and expand this infrastructure with an L2 address hash table so we can support an expanded list of unicast addresses (for bridges, macvlans, OVS, etc). The L2 hash table infrastructure will also allow more generalized n-tuple filter support. This patch creates the bnxt_l2_filter structure and the hash table. This L2 filter structure has the same bnxt_filter_base structure as used in the bnxt_ntuple_filter structure. All currently supported L2 filters will now have an entry in this new table. Note that L2 filters may be created for the VF. VF filters should not be freed when the PF goes down. Add some logic in bnxt_free_l2_filters() to allow keeping the VF filters or to free everything during rmmod. Reviewed-by:

This is in preparation to support user defined L2 (ether) filters, which will have many similarities with ntuple filters. Refactor bnxt_ntuple_filter structure to have a bnxt_filter_base structure that can be re-used by the L2 filters. Reviewed-by:

Matthieu Baerts says: ==================== mptcp: add CurrEstab MIB counter This MIB counter is similar to the one of TCP -- CurrEstab -- available in /proc/net/snmp. This is useful to quickly list the number of MPTCP connections without having to iterate over all of them. Patch 1 prepares its support by adding new helper functions: - MPTCP_DEC_STATS(): similar to MPTCP_INC_STATS(), but this time to decrement a counter. - mptcp_set_state(): similar to tcp_set_state(), to change the state of an MPTCP socket, and to inc/decrement the new counter when needed. Patch 2 uses mptcp_set_state() instead of directly calling inet_sk_state_store() to change the state of MPTCP sockets. Patch 3 and 4 validate the new feature in MPTCP "join" and "diag" selftests. ==================== Signed-off-by:

Add a new MIB counter named MPTCP_MIB_CURRESTAB to count current established MPTCP connections, similar to TCP_MIB_CURRESTAB. This is useful to quickly list the number of MPTCP connections without having to iterate over all of them. This patch adds a new helper function mptcp_set_state(): if the state switches from or to ESTABLISHED state, this newly added counter is incremented. This helper is going to be used in the following patch. Similar to MPTCP_INC_STATS(), a new helper called MPTCP_DEC_STATS() is also needed to decrement a MIB counter. Signed-off-by:

Since commit f5769fae ("net: Namespace-ify sysctl_optmem_max") optmem_max is per-netns, so need of switching to root namespace. It seems trivial to keep the old logic working, so going to keep it for a while (at least, until kernel with netns-optmem_max will be release). Currently, there is a test that checks that optmem_max limit applies to TCP-AO keys and a little benchmark that measures linked-list TCP-AO keys scaling, those are fixed by this.

In unsigned-md5 selftests ip_route_add() is not needed in client_add_ip(): the route was pre-setup in __test_init() => link_init() for subnet, rather than a specific ip-address. Currently, __ip_route_add() mistakenly always sets VRF table to RT_TABLE_MAIN - this seems to have sneaked in during unsigned-md5 tests debugging. That also explains, why ip_route_add_vrf() ignored EEXIST, returned by fib6. Yet, keep EEXIST ignoring in bench-lookups selftests as it's expected that those selftests may add the same (duplicate) routes. Reported-by:
