Add a section to netdev maintainer doc encouraging reviewers to chime in on the mailing list. The questions about "when is it okay to share feedback" keep coming up (most recently at netconf) and the answer is "pretty much always". Extend the section of 7.AdvancedTopics.rst which deals with reviews a little bit to add stuff we had been recommending locally. Signed-off-by:

If an IP address and/or L4 port for NAPT is available from a CT match, the MAE will perform the edits; if no CT lookup has been performed for this packet, the CT lookup did not return a match, or the matched CT entry did not include NAPT, the action will have no effect. Reviewed-by:

The MAE can edit either address, L4 port, or both, for either source or destination. These can't be mixed; i.e. it can edit source addr and source port, but not (say) source addr and dest port. Reviewed-by:

Arseniy Krasnov says: ==================== vsock/virtio/vhost: MSG_ZEROCOPY preparations this patchset is first of three parts of another big patchset for MSG_ZEROCOPY flag support: https://lore.kernel.org/netdev/20230701063947.3422088-1-AVKrasnov@sberdevices.ru/ During review of this series, Stefano Garzarella <sgarzare@redhat.com> suggested to split it for three parts to simplify review and merging: 1) virtio and vhost updates (for fragged skbs) <--- this patchset 2) AF_VSOCK updates (allows to enable MSG_ZEROCOPY mode and read tx completions) and update for Documentation/. 3) Updates for tests and utils. This series enables handling of fragged skbs in virtio and vhost parts. Newly logic won't be triggered, because SO_ZEROCOPY options is still impossible to enable at this moment (next bunch of patches from big set above will enable it). I've included changelog to some patches anyway, because there were some comments during review of last big patchset from the link above.

This adds three tests for MSG_ZEROCOPY feature: 1) SOCK_STREAM tx with different buffers. 2) SOCK_SEQPACKET tx with different buffers. 3) SOCK_STREAM test to read empty error queue of the socket. Patch also works as preparation for the next patches for tools in this patchset: vsock_perf and vsock_uring_test: 1) Adds several new functions to util.c - they will be also used by vsock_uring_test. 2) Adds two new functions for MSG_ZEROCOPY handling to a new source file - such source will be shared between vsock_test, vsock_perf and vsock_uring_test, thus avoiding code copy-pasting.

This adds description of MSG_ZEROCOPY flag support for AF_VSOCK type of socket. Signed-off-by:
-
Arseniy Krasnov authored
For AF_VSOCK, zerocopy tx mode depends on transport, so this option must be set in AF_VSOCK implementation where transport is accessible (if transport is not set during setting SO_ZEROCOPY: for example socket is not connected, then SO_ZEROCOPY will be enabled, but once transport will be assigned, support of this type of transmission will be checked). To handle SO_ZEROCOPY, AF_VSOCK implementation uses SOCK_CUSTOM_SOCKOPT bit, thus handling SOL_SOCKET option operations, but all of them except SO_ZEROCOPY will be forwarded to the generic handler by calling 'sock_setsockopt()'.

strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. This patch eliminates three uses of strncpy(): Firstly, `dest` is expected to be NUL-terminated which is evident by the manual setting of a NUL-byte at size - 1. For this use specifically, strscpy() is a viable replacement due to the fact that it guarantees NUL-termination on the destination buffer. The next two cases should simply be memcpy() as the size of the src string is always 3 and the destination string just wants the first 3 bytes changed. To be clear, there are no buffer overread bugs in the current code as the sizes and offsets are carefully managed such that buffers are NUL-terminated. However, with these changes, the code is now more robust and less ambiguous (and hopefully easier to read).

In very rare cases (I've seen two reports so far about different RTL8125 chip versions) it seems the MAC locks up when link goes down and requires a software reset to get revived. Realtek doesn't publish hw errata information, therefore the root cause is unknown. Realtek vendor drivers do a full hw re-initialization on each link-up event, the slimmed-down variant here was reported to fix the issue for the reporting user. It's not fully clear which parts of the NIC are reset as part of the software reset, therefore I can't rule out side effects. Fixes: f1bce4ad ("r8169: add support for RTL8125") Reported-by:

Breno Leitao says: ==================== net: netconsole: configfs entries for boot target There is a limitation in netconsole, where it is impossible to disable or modify the target created from the command line parameter. (netconsole=...). "netconsole" cmdline parameter sets the remote IP, and if the remote IP changes, the machine needs to be rebooted (with the new remote IP set in the command line parameter). This allows the user to modify a target without the need to restart the machine. This functionality sits on top of the dynamic target reconfiguration that is already implemented in netconsole. The way to modify a boot time target is creating special named configfs directories, that will be associated with the targets coming from `netconsole=...`. Example: Let's suppose you have two netconsole targets defined at boot time:: netconsole=4444@10.0.0.1/eth1,9353@10.0.0.2/12:34:56:78:9a:bc;4444@10.0.0.1/eth1,9353@10.0.0.3/12:34:56:78:9a:bc You can modify these targets in runtime by creating the following targets:: $ mkdir cmdline1 $ cat cmdline1/remote_ip 10.0.0.3 $ echo 0 > cmdline1/enabled $ echo 10.0.0.4 > cmdline1/remote_ip $ echo 1 > cmdline1/enabled ==================== Link: https://lore.kernel.org/r/20231012111401.333798-1-leitao@debian.orgSigned-off-by:

Enable the attachment of a dynamic target to the target created during boot time. The boot-time targets are named as "cmdline\d", where "\d" is a number starting at 0. If the user creates a dynamic target named "cmdline0", it will attach to the first target created at boot time (as defined in the `netconsole=...` command line argument). `cmdline1` will attach to the second target and so forth. If there is no netconsole target created at boot time, then, the target name could be reused. Relevant design discussion: https://lore.kernel.org/all/ZRWRal5bW93px4km@gmail.com/Suggested-by:

For netconsole targets allocated during the boot time (passing netconsole=... argument), netconsole_target->item is not initialized. That is not a problem because it is not used inside configfs. An upcoming patch will be using it, thus, initialize the targets with the name 'cmdline' plus a counter starting from 0. This name will match entries in the configfs later. Suggested-by:

Move alloc_param_target() and its counterpart (free_param_target()) to the bottom of the file. These functions are called mostly at initialization/cleanup of the module, and they should be just above the callers, at the bottom of the file. From a practical perspective, having alloc_param_target() at the bottom of the file will avoid forward declaration later (in the following patch). Nothing changed other than the functions location.

strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. `desc` is expected to be NUL-terminated as evident by the manual NUL-byte assignment. Moreover, NUL-padding does not seem to be necessary. The only caller of efx_mcdi_nvram_metadata() is efx_devlink_info_nvram_partition() which provides a NULL for `desc`: | rc = efx_mcdi_nvram_metadata(efx, partition_type, NULL, version, NULL, 0); Due to this, I am not sure this code is even reached but we should still favor something other than strncpy. Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.

Let's also opt to use the more idiomatic strscpy() usage of (dest, src, sizeof(dest)) rather than (dest, src, SOME_LEN). Typically the pattern of 1) allocate memory for string, 2) copy string into freshly-allocated memory is a candidate for kmemdup_nul() but in this case we are allocating the entirety of the `res` struct and that should stay as is.

These devices have single flow steering logic and two netdev interfaces, which require extra logic to manage IPsec configurations as they performed on netdevs. [1] https://lore.kernel.org/linux-rdma/20180104152544.28919-1-leon@kernel.org/ * 'mlx5-next' of https://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux: net/mlx5: Handle IPsec steering upon master unbind/bind net/mlx5: Configure IPsec steering for ingress RoCEv2 MPV traffic net/mlx5: Configure IPsec steering for egress RoCEv2 MPV traffic net/mlx5: Add create alias flow table function to ipsec roce net/mlx5: Implement alias object allow and create functions net/mlx5: Add alias flow table bits net/mlx5: Store devcom pointer inside IPsec RoCE net/mlx5: Register mlx5e priv to devcom in MPV mode RDMA/mlx5: Send events from IB driver about device affiliation state net/mlx5: Introduce ifc bits for migration in a chunk mode ==================== Link: https://lore.kernel.org/r/20231002083832.19746-1-leon@kernel.orgSigned-off-by:
