Clarify the difference between "interface" and "phy_interface" in struct plat_stmmacenet_data, both by adding a comment, and also renaming "interface" to be "mac_interface". The difference between these are: MAC ----- optional PCS ----- SerDes ----- optional PHY ----- Media ^ ^ mac_interface phy_interface Note that phylink currently only deals with phy_interface.

Jiri Pirko says: ==================== devlink: finish file split and get retire leftover.c This patchset finishes a move Jakub started and Moshe continued in the past. I was planning to do this for a long time, so here it is, finally. This patchset does not change any behaviour. It just splits leftover.c into per-object files and do necessary changes, like declaring functions used from other code, on the way. The last 3 patches are pushing the rest of the code into appropriate existing files. ==================== Link: https://lore.kernel.org/r/20230828061657.300667-1-jiri@resnulli.usSigned-off-by:

In preparations of leftover.c split to individual files, avoid need to have object structures exposed in devl_internal.h and allow to have them maintained in object files. The register/unregister notifications need to know the structures to iterate lists. To avoid the need, introduce per-object register/unregister notification helpers and use them. Signed-off-by:

If failed to set link1_1 to netns client, we should delete link1_1 in the cleanup path. But if set link1_1 to netns client successfully, delete link1_1 will report warning. So it will be safer creating directly the devices in the target namespaces. Reported-by:

While looking at TC_ACT_* handling, the TC_ACT_CONSUMED is only handled in sch_handle_ingress but not sch_handle_egress. This was added via cd11b164 ("net/tc: introduce TC_ACT_REINSERT.") and e5cf1baf ("act_mirred: use TC_ACT_REINSERT when possible") and later got renamed into TC_ACT_CONSUMED via 720f22fe ("net: sched: refactor reinsert action"). The initial work was targeted for ovs back then and only needed on ingress, and the mirred action module also restricts it to only that. However, given it's an API contract it would still make sense to make this consistent to sch_handle_ingress and handle it on egress side in the same way, that is, setting return code to "success" and returning NULL back to the caller as otherwise an action module sitting on egress returning TC_ACT_CONSUMED could lead to an UAF when untreated.

This is in line with what is also done on the ingress side, and from debugging the skb_unref(skb) on dummy xmit and sch_handle_egress() side, it is visible that these are two different skbs with both skb_unref(skb) as true. The two seen skbs are due to mirred doing a skb_clone() internally as use_reinsert is false in tcf_mirred_act() for egress. This was initially reported by Gal.

Hariprasad Kelam says: ==================== octeontx2-af: misc MAC block changes This series of patches adds recent changes added in MAC (CGX/RPM) block. Patch1: Adds new LMAC mode supported by CN10KB silicon Patch2: In a scenario where system boots with no cgx devices, currently AF driver treats this as error as a result no interfaces will work. This patch relaxes this check, such that non cgx mapped netdev devices will work. Patch3: This patch adds required lmac validation in MAC block APIs. Patch4: Prints error message incase, no netdev is mapped with given cgx,lmac pair. ==================== Signed-off-by: -
Hariprasad Kelam authored
During AF driver initialization, it creates a mapping between pf to cgx,lmac pair. Whenever there is a physical link change, using this mapping driver forwards the message to the associated netdev. This patch prints error message incase of cgx,lmac pair is not associated with any pf netdev. Signed-off-by:

Upon physical link change, firmware reports to the kernel about the change along with the details like speed, lmac_type_id, etc. Kernel derives lmac_type based on lmac_type_id received from firmware.

Sabrina Dubroca says: ==================== tls: expand tls_cipher_size_desc to simplify getsockopt/setsockopt Commit 2d2c5ea2 ("net/tls: Describe ciphers sizes by const structs") introduced tls_cipher_size_desc to describe the size of the fields of the per-cipher crypto_info structs, and commit ea7a9d88 ("net/tls: Use cipher sizes structs") used it, but only in tls_device.c and tls_device_fallback.c, and skipped converting similar code in tls_main.c and tls_sw.c. This series expands tls_cipher_size_desc (renamed to tls_cipher_desc to better fit this expansion) to fully describe a cipher: - offset of the fields within the per-cipher crypto_info - size of the full struct (for copies to/from userspace) - offload flag - algorithm name used by SW crypto With these additions, we can remove ~350L of switch (crypto_info->cipher_type) { ... } from tls_set_device_offload, tls_sw_fallback_init, do_tls_getsockopt_conf, do_tls_setsockopt_conf, tls_set_sw_offload (mainly do_tls_getsockopt_conf and tls_set_sw_offload). This series also adds the ARIA ciphers to the tls selftests, and some more getsockopt/setsockopt tests to cover more of the code changed by this series. ==================== Link: https://lore.kernel.org/r/cover.1692977948.git.sd@queasysnail.netSigned-off-by:

We can get rid of some local variables, but we have to keep nonce_size because tls1.3 uses nonce_size = 0 for all ciphers. We can also drop the runtime sanity checks on iv/rec_seq/tag size, since we have compile time checks on those values. Signed-off-by:

Every cipher uses the same code to update its crypto_info struct based on the values contained in the cctx, with only the struct type and size/offset changing. We can get those from tls_cipher_desc, and use a single pair of memcpy and final copy_to_user. Signed-off-by:
