In a rare case where we redirect local packets from veth to lo, these packets fail to pass the source validation when rp_filter is turned on, as the tracing shows: <...>-311708 [040] ..s1 7951180.957825: fib_table_lookup: table 254 oif 0 iif 1 src 10.53.180.130 dst 10.53.180.130 tos 0 scope 0 flags 0 <...>-311708 [040] ..s1 7951180.957826: fib_table_lookup_nh: nexthop dev eth0 oif 4 src 10.53.180.130 So, the fib table lookup returns eth0 as the nexthop even though the packets are local and should be routed to loopback nonetheless, but they can't pass the dev match check in fib_info_nh_uses_dev() without this patch. It should be safe to relax this check for this special case, as normally packets coming out of loopback device still have skb_dst so they won't even hit this slow path.

Ido Schimmel says: ==================== mlxsw: Two fixes This patchset contains two fixes for mlxsw. Patch #1 from Petr fixes an issue in which DSCP rewrite can occur even if the egress port was switched to Trust L2 mode where priority mapping is based on PCP. Patch #2 fixes a problem where packets can be learned on a non-existing FID if a tc filter with a redirect action is configured on a bridged port. The problem and fix are explained in detail in the commit message. Please consider both patches for 5.2.y ==================== Signed-off-by: -
Ido Schimmel authored
The switch periodically sends notifications about learned FDB entries. Among other things, the notification includes the FID (Filtering Identifier) and the port on which the MAC was learned. In case the driver does not have the FID defined on the relevant port, the following error will be periodically generated: mlxsw_spectrum2 0000:06:00.0 swp32: Failed to find a matching {Port, VID} following FDB notification This is not supposed to happen under normal conditions, but can happen if an ingress tc filter with a redirect action is installed on a bridged port. The redirect action will cause the packet's FID to be changed to the dummy FID and a learning notification will be emitted with this FID - which is not defined on the bridged port. Fix this by having the driver ignore learning notifications generated with the dummy FID and delete them from the device. Another option is to chain an ignore action after the redirect action which will cause the device to disable learning, but this means that we need to consume another action whenever a redirect action is used. In addition, the scenario described above is merely a corner case.

Spectrum systems use DSCP rewrite map to update DSCP field in egressing packets to correspond to priority that the packet has. Whether rewriting will take place is determined at the point when the packet ingresses the switch: if the port is in Trust L3 mode, packet priority is determined from the DSCP map at the port, and DSCP rewrite will happen. If the port is in Trust L2 mode, 802.1p is used for packet prioritization, and no DSCP rewrite will happen. The driver determines the port trust mode based on whether any DSCP prioritization rules are in effect at given port. If there are any, trust level is L3, otherwise it's L2. When the last DSCP rule is removed, the port is switched to trust L2. Under that scenario, if DSCP of a packet should be rewritten, it should be rewritten to 0. However, when switching to Trust L2, the driver neglects to also update the DSCP rewrite map. The last DSCP rule thus remains in effect, and packets egressing through this port, if they have the right priority, will have their DSCP set according to this rule. Fix by first configuring the rewrite map, and only then switching to trust L2 and bailing out. Fixes: b2b1dab6 ("mlxsw: spectrum: Support ieee_setapp, ieee_delapp") Signed-off-by:

For qdisc's that support TC filters and set TCQ_F_CAN_BYPASS, notably fq_codel, it makes no sense to let packets bypass the TC filters we setup in any scenario, otherwise our packets steering policy could not be enforced. This can be reproduced easily with the following script: ip li add dev dummy0 type dummy ifconfig dummy0 up tc qd add dev dummy0 root fq_codel tc filter add dev dummy0 parent 8001: protocol arp basic action mirred egress redirect dev lo tc filter add dev dummy0 parent 8001: protocol ip basic action mirred egress redirect dev lo ping -I dummy0 192.168.112.1 Without this patch, packets are sent directly to dummy0 without hitting any of the filters. With this patch, packets are redirected to loopback as expected. This fix is not perfect, it only unsets the flag but does not set it back because we have to save the information somewhere in the qdisc if we really want that. Note, both fq_codel and sfq clear this flag in their ->bind_tcf() but this is clearly not sufficient when we don't use any class ID.

Since "rds_ib_free_frmr" and "rds_ib_free_frmr_list" simply put the FRMR memory segments on the "drop_list" or "free_list", and it is the job of "rds_ib_flush_mr_pool" to reap those entries by ultimately issuing a "IB_WR_LOCAL_INV" work-request, we need to trigger and then wait for all those memory segments attached to a particular connection to be fully released before we can move on to release the QP, CQ, etc. So we make "rds_ib_conn_path_shutdown" wait for one more atomic_t called "i_fastreg_inuse_count" that keeps track of how many FRWR memory segments are out there marked "FRMR_IS_INUSE" (and also wake_up rds_ib_ring_empty_wait, as they go away).

In order to: 1) avoid a silly bouncing between "clean_list" and "drop_list" triggered by function "rds_ib_reg_frmr" as it is releases frmr regions whose state is not "FRMR_IS_FREE" right away. 2) prevent an invalid access error in a race from a pending "IB_WR_LOCAL_INV" operation with a teardown ("dma_unmap_sg", "put_page") and de-registration ("ib_dereg_mr") of the corresponding memory region.

Waiting for activity on the "clean_list" to quiesce is no substitute for proper locking. We can have multiple threads competing for "llist_del_first" via "rds_ib_reuse_mr", and a single thread competing for "llist_del_all" and "llist_del_first" via "rds_ib_flush_mr_pool". Since "llist_del_first" depends on "list->first->next" not to change in the midst of the operation, simply waiting for all current calls to "rds_ib_reuse_mr" to quiesce across all CPUs is woefully inadequate: By the time "wait_clean_list_grace" is done iterating over all CPUs to see that there is no concurrent caller to "rds_ib_reuse_mr", a new caller may have just shown up on the first CPU. Furthermore, <linux/llist.h> explicitly calls out the need for locking: * Cases where locking is needed: * If we have multiple consumers with llist_del_first used in one consumer, * and llist_del_first or llist_del_all used in other consumers, * then a lock is needed. Also, while at it, drop the unused "pool" parameter from "list_to_llist_nodes". Signed-off-by:

In the context of FRMR (ib_frmr.c): Memory regions make it onto the "clean_list" via "rds_ib_flush_mr_pool", after the memory region has been posted for invalidation via "rds_ib_post_inv". At that point in time, "fr_state" may still be in state "FRMR_IS_INUSE", since the only place where "fr_state" transitions to "FRMR_IS_FREE" is in "rds_ib_mr_cqe_handler", which is triggered by a tasklet. So in case we notice that "fr_state != FRMR_IS_FREE" (see below), we wait for "fr_inv_done" to trigger with a maximum of 10msec. Then we check again, and only put the memory region onto the drop_list (via "rds_ib_free_frmr") in case the situation remains unchanged. This avoids the problem of memory-regions bouncing between "clean_list" and "drop_list" before they even have a chance to be properly invalidated. Signed-off-by:

Recently, fl_flow_key->indev_ifindex int field was refactored into flow_dissector_key_meta field. With this, flower classifier also sets FLOW_DISSECTOR_KEY_META flow dissector key. However, mlx5 flower dissector validation code rejects filters that use flow dissector keys that are not supported.

Currently, tunnel attributes are parsed and inner header matching is used only when flow dissector specifies match on some of the supported encapsulation fields. When user tries to offload tc filter that doesn't match any encapsulation fields on tunnel device, mlx5 tc layer incorrectly sets to match packet header keys on encap header (outer header) and firmware rejects the rule with syndrome 0x7e1579 when creating new flow group. Change __parse_cls_flower() to determine whether tunnel is used based on fitler_dev tunnel info, instead of determining it indirectly by checking flow dissector enc keys.
