Add infrastructure for phylink_pcs to the mv88e6xxx driver. This involves adding a mac_select_pcs() hook so we can pass the PCS to phylink at the appropriate time, and a PCS initialisation function. As the various chip implementations are converted to use phylink_pcs, they are no longer reliant on the legacy phylink behaviour. We detect this by the use of this infrastructure, or the lack of any serdes. Signed-off-by:

As we now always use a fixed-link for DSA and CPU ports, we no longer need the hack in the Marvell code to make this work. Remove it. This is especially important with the conversion of DSA drivers to phylink_pcs, as the PCS code only gets called if we are using phylink for the port. Signed-off-by:

We now have a regmap cache which uses a maple tree to store the register state, this is a more modern data structure and the regmap level code using it makes a number of assumptions better tuned for modern hardware than those made by the rbtree cache type that the at9331 driver uses. Switch the ar9331 driver to use the more modern data structure. This should have minimal practical impact, it's mainly code modernisation. Signed-off-by:

Guillaume Nault says: ==================== net: Mark the sk parameter of routing functions as 'const'. The sk_getsecid security hook prevents the use of a const sk pointer in several routing functions. Since this hook should only read sk data, make its sk argument const (patch 1), then constify the sk parameter of various routing functions (patches 2-4). Build-tested with make allmodconfig. ==================== Signed-off-by: -

The dev_rx_discards counter will increment by one when an interface is toggled up and down. The main reason is that the driver first sends a `NFP_NET_CFG_CTRL_ENABLE` configuration packet to the NIC to perform port initialisation when an interface is set up. But there is a race between physical link up and free list queue initialization which may lead to the configuration packet being discarded. To address this problem a new bit NFP_NET_CFG_CTRL_FREELIST_EN is added to perform free list initialisation on the NIC. The FREELIST_EN should be sent in advance to initialize free list queue. When a port is set to down, FREELIST_EN should be sent after CTRL_ENABLE to avoid packet discards. Signed-off-by:

Matthieu Baerts says: ==================== selftests: mptcp: join: pass args in new env vars In this series, Geliang did some refactoring in the mptcp_join.sh file. Patch 1 reduces the scope of some global env vars, only used by some tests: easier to deal with. Patch 2 uses a dedicated env var for fastclose case instead of re-using addr_nr_ns2 with embedded info, clearer. Patch 3 is similar but for the fullmesh case. Patch 4 moves a positional but optional argument of run_tests() to an env var like it has already been done with the other args, cleaner. ==================== Link: https://lore.kernel.org/r/20230712-upstream-net-next-20230712-selftests-mptcp-use-local-env-v1-0-f1c8b62fbf95@tessares.netSigned-off-by:

We are utilizing BPF LSM to monitor BPF operations within our container environment. When we add support for raw_tracepoint, it hits below error. ; (const void *)attr->raw_tracepoint.name); 27: (79) r3 = *(u64 *)(r2 +0) access beyond the end of member map_type (mend:4) in struct (anon) with off 0 size 8 It can be reproduced with below BPF prog. SEC("lsm/bpf") int BPF_PROG(bpf_audit, int cmd, union bpf_attr *attr, unsigned int size) { switch (cmd) { case BPF_RAW_TRACEPOINT_OPEN: bpf_printk("raw_tracepoint is %s", attr->raw_tracepoint.name); break; default: break; } return 0; } The reason is that when accessing a field in a union, such as bpf_attr, if the field is located within a nested struct that is not the first member of the union, it can result in incorrect field verification. union bpf_attr { struct { __u32 map_type; <<<< Actually it will find that field. __u32 key_size; __u32 value_size; ... }; ... struct { __u64 name; <<<< We want to verify this field. __u32 prog_fd; } raw_tracepoint; }; Considering the potential deep nesting levels, finding a perfect solution to address this issue has proven challenging. Therefore, I propose a solution where we simply skip the verification process if the field in question is located within a union.
