2023-04-02i40e: Add support for VF to specify its primary MAC addressSylwester Dziedziuch
Currently in the i40e driver there is no implementation of different MAC address handling depending on whether it is a legacy or primary. Introduce new checks for VF to be able to specify its primary MAC address based on the VIRTCHNL_ETHER_ADDR_PRIMARY type. Primary MAC address are treated differently compared to legacy ones in a scenario where: 1. If a unicast MAC is being added and it's specified as VIRTCHNL_ETHER_ADDR_PRIMARY, then replace the current default_lan_addr.addr. 2. If a unicast MAC is being deleted and it's type is specified as VIRTCHNL_ETHER_ADDR_PRIMARY, then zero the hw_lan_addr.addr.

2023-03-31tcp: Refine SYN handling for PAWS.Kuniyuki Iwashima
Our Network Load Balancer (NLB) [0] has multiple nodes with different IP addresses, and each node forwards TCP flows from clients to backend targets. NLB has an option to preserve the client's source IP address and port when routing packets to backend targets. [1] When a client connects to two different NLB nodes, they may select the same backend target. Then, if the client has used the same source IP and port, the two flows at the backend side will have the same 4-tuple. While testing around such cases, I saw these sequences on the backend target. IP 10.0.0.215.60000 > 10.0.3.249.10000: Flags [S], seq 2819965599, win 62727, options [mss 8365,sackOK,TS val 1029816180 ecr 0,nop,wscale 7], length 0 IP 10.0.3.249.10000 > 10.0.0.215.60000: Flags [S.], seq 3040695044, ack 2819965600, win 62643, options [mss 8961,sackOK,TS val 1224784076 ecr 1029816180,nop,wscale 7], length 0 IP 10.0.0.215.60000 > 10.0.3.249.10000: Flags [.], ack 1, win 491, options [nop,nop,TS val 1029816181 ecr 1224784076], length 0 IP 10.0.0.215.60000 > 10.0.3.249.10000: Flags [S], seq 2681819307, win 62727, options [mss 8365,sackOK,TS val 572088282 ecr 0,nop,wscale 7], length 0 IP 10.0.3.249.10000 > 10.0.0.215.60000: Flags [.], ack 1, win 490, options [nop,nop,TS val 1224794914 ecr 1029816181,nop,nop,sack 1 {4156821004:4156821005}], length 0 It seems to be working correctly, but the last ACK was generated by tcp_send_dupack() and PAWSEstab was increased. This is because the second connection has a smaller timestamp than the first one. In this case, we should send a dup ACK in tcp_send_challenge_ack() to increase the correct counter and rate-limit it properly. Let's check the SYN flag after the PAWS tests to avoid adding unnecessary overhead for most packets.

Patches 3-4 implement an ethtool-like python tool to test the spec.

2023-03-30octeontx2-af: update type of prof fields in nix_aw_enq_reqSimon Horman
Update type of prof and prof_mask fields in nix_as_enq_req from u64 to struct nix_bandprof_s, which is 128 bits wide.

currently, users can skip individual test cases by means of writing "skip": "yes" in the scenario file. Extend this functionality, introducing 'dependsOn': it's optional property like "skip", but the value contains a command (for example, a probe on iproute2 to check if it supports a specific feature). If such property is present, tdc executes that command and skips the test when the return value is non-zero.

This selftest was introduced recently in the commit cited below. It misses several check_err() invocations to actually verify that the previous command succeeded. When these are added, the first one fails, because besides the addresses added by hand, there can be a link-local address added by the kernel. Adjust the check to expect at least three addresses instead of exactly three, and add the missing check_err's. Furthermore, the explanatory comments assume that the address with no protocol is $addr2, when in fact it is $addr3. Update the comments.

2023-03-30net: dsa: fix db type confusion in host fdb/mdb add/delVladimir Oltean
We have the following code paths: Host FDB (unicast RX filtering): dsa_port_standalone_host_fdb_add() dsa_port_bridge_host_fdb_add() | | +--------------+ +------------+ | | v v dsa_port_host_fdb_add() dsa_port_standalone_host_fdb_del() dsa_port_bridge_host_fdb_del() | | +--------------+ +------------+ | | v v dsa_port_host_fdb_del() Host MDB (multicast RX filtering): dsa_port_standalone_host_mdb_add() dsa_port_bridge_host_mdb_add() | | +--------------+ +------------+ | | v v dsa_port_host_mdb_add() dsa_port_standalone_host_mdb_del() dsa_port_bridge_host_mdb_del() | | +--------------+ +------------+ | | v v dsa_port_host_mdb_del() The logic added by commit 5e8a1e03aa4d ("net: dsa: install secondary unicast and multicast addresses as host FDB/MDB") zeroes out db.bridge.num if the switch doesn't support ds->fdb_isolation (the majority doesn't). This is done for a reason explained in commit c26933639b54 ("net: dsa: request drivers to perform FDB isolation"). Taking a single code path as example - dsa_port_host_fdb_add() - the others are similar - the problem is that this function handles: - DSA_DB_PORT databases, when called from dsa_port_standalone_host_fdb_add() - DSA_DB_BRIDGE databases, when called from dsa_port_bridge_host_fdb_add() So, if dsa_port_host_fdb_add() were to make any change on the "bridge.num" attribute of the database, this would only be correct for a DSA_DB_BRIDGE, and a type confusion for a DSA_DB_PORT bridge. However, this bug is without consequences, for 2 reasons: - dsa_port_standalone_host_fdb_add() is only called from code which is (in)directly guarded by dsa_switch_supports_uc_filtering(ds), and that function only returns true if ds->fdb_isolation is set. So, the code only executed for DSA_DB_BRIDGE databases. - Even if the code was not dead for DSA_DB_PORT, we have the following memory layout: struct dsa_bridge { struct net_device *dev; unsigned int num; bool tx_fwd_offload; refcount_t refcount; }; struct dsa_db { enum dsa_db_type type; union { const struct dsa_port *dp; // DSA_DB_PORT struct dsa_lag lag; struct dsa_bridge bridge; // DSA_DB_BRIDGE }; }; So, the zeroization of dsa_db :: bridge :: num on a dsa_db structure of type DSA_DB_PORT would access memory which is unused, because we only use dsa_db :: dp for DSA_DB_PORT, and this is mapped at the same address with dsa_db :: dev for DSA_DB_BRIDGE, thanks to the union definition. It is correct to fix up dsa_db :: bridge :: num only from code paths that come from the bridge / switchdev, so move these there.

2023-03-30dm: fix __send_duplicate_bios() to always allow for splitting IOMike Snitzer
Commit 7dd76d1feec70 ("dm: improve bio splitting and associated IO accounting") only called setup_split_accounting() from __send_duplicate_bios() if a single bio were being issued. But the case where duplicate bios are issued must call it too. Otherwise the bio won't be split and resubmitted (via recursion through block core back to DM) to submit the later portions of a bio (which may map to an entirely different target). For example, when discarding an entire DM striped device with the following DM table: vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048 vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048 Before (broken, discards the first striped target's devices twice): device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872 device-mapper: striped: target_stripe=0, bdev=7:0, start=2049 len=22528 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=22528 After (works as expected): device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872 device-mapper: striped: target_stripe=0, bdev=7:2, start=2048 len=22528 device-mapper: striped: target_stripe=1, bdev=7:3, start=2048 len=22528 Fixes: 7dd76d1feec70 ("dm: improve bio splitting and associated IO accounting") Cc: stable@vger.kernel.org Reported-by: Orange Kao <orange@aiven.io> Signed-off-by: Mike Snitzer <snitzer@kernel.org>
2023-03-30dm: fix improper splitting for abnormal biosMike Snitzer
"Abnormal" bios include discards, write zeroes and secure erase. By no longer passing the calculated 'len' pointer, commit 7dd06a2548b2 ("dm: allow dm_accept_partial_bio() for dm_io without duplicate bios") took a senseless approach to disallowing dm_accept_partial_bio() from working for duplicate bios processed using __send_duplicate_bios(). It inadvertently and incorrectly stopped the use of 'len' when initializing a target's io (in alloc_tio). As such the resulting tio could address more area of a device than it should. For example, when discarding an entire DM striped device with the following DM table: vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048 vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048 Before this fix: device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=102400 blkdiscard: attempt to access beyond end of device loop0: rw=2051, sector=2048, nr_sectors = 102400 limit=81920 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=102400 blkdiscard: attempt to access beyond end of device loop1: rw=2051, sector=2048, nr_sectors = 102400 limit=81920 After this fix; device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872 Fixes: 7dd06a2548b2 ("dm: allow dm_accept_partial_bio() for dm_io without duplicate bios") Cc: stable@vger.kernel.org Reported-by: Orange Kao <orange@aiven.io> Signed-off-by: Mike Snitzer <snitzer@kernel.org>
