The two tests that make use of multicast routig (router.sh and router_multicast.sh) are currently failing in the netdev CI because the kernel is missing multicast routing support. Fix by adding the required config entries. Fixes: 6d4efada ("selftests: forwarding: Add multicast routing test") Signed-off-by:

Merge netdev bits of io_uring busy polling support. Jens Axboe says: ==================== io_uring: add napi busy polling support I finally got around to testing this patchset in its current form, and results look fine to me. It Works. Using the basic ping/pong test that's part of the liburing addition, without enabling NAPI I get: Stock settings, no NAPI, 100k packets: rtt(us) min/avg/max/mdev = 31.730/37.006/87.960/0.497 and with -t10 -b enabled: rtt(us) min/avg/max/mdev = 23.250/29.795/63.511/1.203 In short, this patchset enables per io_uring NAPI enablement, rather than need to enable that globally. This allows targeted NAPI usage with io_uring. Here's Stefan's v15 posting, which predates this one: https://lore.kernel.org/io-uring/20230608163839.2891748-1-shr@devkernel.io/ ==================== Link: https://lore.kernel.org/r/20240206163422.646218-1-axboe@kernel.dkSigned-off-by:

This adds the napi_busy_loop_rcu() function. This function assumes that the calling function is already holding the rcu read lock and napi_busy_loop() does not need to take the rcu read lock. Add a NAPI_F_NO_SCHED flag, which tells __napi_busy_loop() to abort if we need to reschedule rather than drop the RCU read lock and reschedule. Signed-off-by:

This splits off the key part of the napi_busy_poll function into its own function, __napi_busy_poll, and changes the prefer_busy_poll bool to be flag based to allow passing in more flags in the future. This is done in preparation for an additional napi_busy_poll() function, that doesn't take the rcu_read_lock(). The new function is introduced in the next patch. Signed-off-by:

On early detection of wwan device in fastboot mode, driver sets up CLDMA0 HW tx/rx queues for raw data transfer and then create fastboot port to userspace. Application can use this port to flash firmware and collect core dump by fastboot protocol commands. E.g., flash firmware through fastboot port: - "download:%08x": write data to memory with the download size. - "flash:%s": write the previously downloaded image to the named partition. - "reboot": reboot the device.

Matthew Wood says: ==================== netconsole: Add userdata append support Add the ability to add custom userdata to every outbound netconsole message as a collection of key/value pairs, allowing users to add metadata to every netconsole message which can be used for for tagging, filtering, and aggregating log messages. In a previous patch series the ability to prepend the uname release was added towards the goals above. This patch series builds on that idea to allow any userdata, keyed by a user provided name, to be included in netconsole messages.

Append userdata to outgoing unfragmented (<1000 bytes) netconsole messages. When sending messages the userdata string is already formatted and stored in netconsole_target->userdata_complete. Always write the outgoing message to buf, so userdata can be appended in a standard fashion. This is a change from only using buf when the release needs to be prepended to the message.

Store a formatted string for userdata that will be appended to netconsole messages. The string has a capacity of 4KB, as calculated by the userdatum entry length of 256 bytes and a max of 16 userdata entries. Update the stored netconsole_target->userdata_complete string with the new formatted userdata values when a userdatum is created, edited, or removed. Each userdata entry contains a trailing newline, which will be formatted as such in netconsole messages:: 6.7.0-rc8-virtme,12,500,1646292204,-;test release=foo something=bar 6.7.0-rc8-virtme,12,500,1646292204,-;another test release=foo something=bar Enforcement of MAX_USERDATA_ITEMS is done in userdatum_make_item; update_userdata will not check for this case but will skip any userdata children over the limit of MAX_USERDATA_ITEMs. If a userdata entry/dir is created but no value is provided, that entry will be skipped. This is in part because update_userdata() can't be called in userdatum_make_item() since the item will not have been added to the userdata config_group children yet. To preserve the experience of adding an empty userdata that doesn't show up in the netconsole messages, purposefully skip empty userdata items even when update_userdata() can be called.

Create configfs machinery for netconsole userdata appending, which depends on CONFIG_NETCONSOLE_DYNAMIC (for configfs interface). Add a userdata config_group to netconsole_target for managing userdata entries as a tree under the netconsole configfs subsystem. Directory names created under the userdata directory become userdatum keys; the userdatum value is the content of the value file. Include the minimum-viable-changes for userdata configfs config_group. init_target_config_group() ties in the complete configfs machinery to avoid unused func/variable errors during build. Initializing the netconsole_target->group is moved to init_target_config_group, which will also init and add the userdata config_group. Each userdatum entry has a limit of 256 bytes (54 for the key/directory, 200 for the value, and 2 for '=' and '\n' characters), which is enforced by the configfs functions for updating the userdata config_group. When a new netconsole_target is created, initialize the userdata config_group and add it as a default group for netconsole_target config_group, allowing the userdata configfs sub-tree to be presented in the netconsole configfs tree under the userdata directory.

Biju Das says: ==================== Add HW checksum offload support for RZ/G2L GbEthernet IP This patch series aims to add HW checksum offload supported by TOE module found on the RZ/G2L Gb ethernet IP. TOE has hardware support for calculating IP header and TCP/UDP/ICMP checksum for both IPv4 and IPv6. For Rx, the 4-byte result of checksum calculation is attached to the Ethernet frames.First 2-bytes is result of IPv4 header checksum and next 2-bytes is TCP/UDP/ICMP checksum. If a frame does not have checksum error, 0x0000 is attached as checksum calculation result. For unsupported frames 0xFFFF is attached as checksum calculation result. In case of an IPv6 packet, IPv4 checksum is always set to 0xFFFF. For Tx, the result of checksum calculation is set to the checksum field of each IPv4 Header/TCP/UDP/ICMP of ethernet frames. For the unsupported frames, those fields are not changed. If a transmission frame is an UDPv4 frame and its checksum value in the UDP header field is 0x0000, TOE does not calculate checksum for UDP part of this frame as it is optional function as per standards. Add Tx/Rx checksum offload supported by TOE for IPv4 and TCP/UDP protocols.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for net: 1) Narrow down target/match revision to u8 in nft_compat. 2) Bail out with unused flags in nft_compat. 3) Restrict layer 4 protocol to u16 in nft_compat. 4) Remove static in pipapo get command that slipped through when reducing set memory footprint. 5) Follow up incremental fix for the ipset performance regression, this includes the missing gc cancellation, from Jozsef Kadlecsik. 6) Allow to filter by zone 0 in ctnetlink, do not interpret zone 0 as no filtering, from Felix Huettner. 7) Reject direction for NFT_CT_ID. 8) Use timestamp to check for set element expiration while transaction is handled to prevent garbage collection from removing set elements that were just added by this transaction. Packet path and netlink dump/get path still use current time to check for expiration. 9) Restore NF_REPEAT in nfnetlink_queue, from Florian Westphal. 10) map_index needs to be percpu and per-set, not just percpu. At this time its possible for a pipapo set to fill the all-zero part with ones and take the 'might have bits set' as 'start-from-zero' area. From Florian Westphal. This includes three patches: - Change scratchpad area to a structure that provides space for a per-set-and-cpu toggle and uses it of the percpu one. - Add a new free helper to prepare for the next patch. - Remove the scratch_aligned pointer and makes AVX2 implementation use the exact same memory addresses for read/store of the matching state. netfilter pull request 24-02-08 * tag 'nf-24-02-08' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nft_set_pipapo: remove scratch_aligned pointer netfilter: nft_set_pipapo: add helper to release pcpu scratch area netfilter: nft_set_pipapo: store index in scratch maps netfilter: nft_set_rbtree: skip end interval element from gc netfilter: nfnetlink_queue: un-break NF_REPEAT netfilter: nf_tables: use timestamp to check for set element timeout netfilter: nft_ct: reject direction for ct id netfilter: ctnetlink: fix filtering for zone 0 netfilter: ipset: Missing gc cancellations fixed netfilter: nft_set_pipapo: remove static in nft_pipapo_get() netfilter: nft_compat: restrict match/target protocol to u16 netfilter: nft_compat: reject unused compat flag netfilter: nft_compat: narrow down revision to unsigned 8-bits ==================== Link: https://lore.kernel.org/r/20240208112834.1433-1-pablo@netfilter.orgSigned-off-by:Paolo Abeni <pabeni@redhat.com>

use ->scratch for both avx2 and the generic implementation. After previous change the scratch->map member is always aligned properly for AVX2, so we can just use scratch->map in AVX2 too. The alignoff delta is stored in the scratchpad so we can reconstruct the correct address to free the area again.

After next patch simple kfree() is not enough anymore, so add a helper for it. Reviewed-by:

Pipapo needs a scratchpad area to keep state during matching. This state can be large and thus cannot reside on stack. Each set preallocates percpu areas for this. On each match stage, one scratchpad half starts with all-zero and the other is inited to all-ones. At the end of each stage, the half that starts with all-ones is always zero. Before next field is tested, pointers to the two halves are swapped, i.e. resmap pointer turns into fill pointer and vice versa. After the last field has been processed, pipapo stashes the index toggle in a percpu variable, with assumption that next packet will start with the all-zero half and sets all bits in the other to 1. This isn't reliable. There can be multiple sets and we can't be sure that the upper and lower half of all set scratch map is always in sync (lookups can be conditional), so one set might have swapped, but other might not have been queried. Thus we need to keep the index per-set-and-cpu, just like the scratchpad. Note that this bug fix is incomplete, there is a related issue. avx2 and normal implementation might use slightly different areas of the map array space due to the avx2 alignment requirements, so m->scratch (generic/fallback implementation) and ->scratch_aligned (avx) may partially overlap. scratch and scratch_aligned are not distinct objects, the latter is just the aligned address of the former. After this change, write to scratch_align->map_index may write to scratch->map, so this issue becomes more prominent, we can set to 1 a bit in the supposedly-all-zero area of scratch->map[]. A followup patch will remove the scratch_aligned and makes generic and avx code use the same (aligned) area. Its done in a separate change to ease review.
