Jiri Pirko says: ==================== devlink: fix order of port and netdev register in drivers Some of the drivers use wrong order in registering devlink port and netdev, registering netdev first. That was not intended as the devlink port is some sort of parent for the netdev. Fix the ordering. Note that the follow-up patchset is going to make this ordering mandatory. ==================== Link: https://lore.kernel.org/r/20220926110938.2800005-1-jiri@resnulli.usSigned-off-by:

To work around a misbehavior of the compiler's ability to see into composite flexible array structs (as detailed in the coming memcpy() hardening series[1]), split the memcpy() of the header and the payload so no false positive run-time overflow warning will be generated. This split already existed for the "firstfrag" case, so just generalize the logic further.

Daniel Golle authored
As sizeof(hwe->data) can now longer be used as the actual size depends on foe_entry_size, in commit 9d8cb4c0 ("net: ethernet: mtk_eth_soc: add foe_entry_size to mtk_eth_soc") the use of sizeof(hwe->data) is hence replaced. However, replacing it with ppe->eth->soc->foe_entry_size is wrong as foe_entry_size represents the size of the whole descriptor and not just the 'data' field. Fix this by subtracing the size of the only other field in the struct 'ib1', so we actually end up with the correct size to be copied to the data field. Reported-by:

Michael Weiß says: ==================== net: openvswitch: metering and conntrack in userns Currently using openvswitch in a non-initial user namespace, e.g., an unprivileged container, is possible but without metering and conntrack support. This is due to the restriction of the corresponding Netlink interfaces to the global CAP_NET_ADMIN. This simple patches switch from GENL_ADMIN_PERM to GENL_UNS_ADMIN_PERM in several cases to allow this also for the unprivileged container use case. We tested this for unprivileged containers created by the container manager of GyroidOS (gyroidos.github.io). However, for other container managers such as LXC or systemd which provide unprivileged containers this should be apply equally. ==================== Link: https://lore.kernel.org/r/20220923133820.993725-1-michael.weiss@aisec.fraunhofer.deSigned-off-by:

I have included several of Rolf's patches in the series where appropriate (with slight modifications). After this series is applied, many more messages from this driver will come with driver/device information. Additionally, most messages (especially debug messages) have been condensed onto one line (as KERN_CONT messages get split).

This driver seems to have been written under the assumption that messages can be continued arbitrarily. I'm not when this changed (if ever), but such ad-hoc continuations are liable to be rudely interrupted. Convert all such instances to single prints. This loses a bit of timing information (such as when a line was constructed piecemeal as the function executed), but it's easy to add a few prints if necessary. This also adds newlines to the ends of any prints without them. Since (almost every) debug print included the name of the function, include it automatically. Signed-off-by:

Remove all the single-use debug conditionals, and just collect the debug defines at the top of the file. HMD seems like it is used for general debug info, so just redefine it as pr_debug. Additionally, instead of using the default loglevel, use the debug loglevel for debugging. Signed-off-by:

Practical experience (and advice from Alexei) tell us that bitfields in structs lead to un-optimized assembly code. I've verified this change does lead to better x86_64 assembly, both via objdump and playing with code snippets in godbolt.org. Using scripts/bloat-o-meter shows the code size is reduced with 24 bytes for xdp_convert_buff_to_frame() that gets inlined e.g. in i40e_xmit_xdp_tx_ring() which were used for microbenchmarking. Microbenchmarking results do show improvements, but very small and varying between 0.5 to 2 nanosec improvement per packet. The member @metasize is changed from u8 to u32. Future users of this area could split this into two u16 fields. I've also benchmarked with two u16 fields showing equal performance gains and code size reduction. The moved member @frame_sz doesn't change sizeof struct due to existing padding. Like xdp_buff member @frame_sz is placed next to @flags, which allows compiler to optimize assignment of these.

Vladimir Oltean says: ==================== Improve tsn_lib selftests for future distributed tasks Some of the boards I am working with are limited in the number of ports that they offer, and as more TSN related selftests are added, it is important to be able to distribute the work among multiple boards. A large part of implementing that is ensuring network-wide synchronization, but also permitting more streams of data to flow through the network. There is the more important aspect of also coordinating the timing characteristics of those streams, and that is also something that is tackled, although not in this modest patch set. The goal here is not to introduce new selftests yet, but just to lay a better foundation for them. These patches are a part of the cleanup work I've done while working on selftests for frame preemption. They are regression-tested with psfp.sh. ==================== Link: https://lore.kernel.org/r/20220923210016.3406301-1-vladimir.oltean@nxp.comSigned-off-by:

We can make the phc2sys helper not only synchronize a PHC to CLOCK_REALTIME, which is what it currently does, but also CLOCK_REALTIME to a PHC, which is going to be needed in distributed TSN tests. Instead of making the complexity of the arguments passed to phc2sys_start() explode, we can let it figure out the sync direction automatically, based on ptp4l's port states. Towards that goal, pass just the path to the desired ptp4l instance's UNIX domain socket, and remove the $if_name argument (from which it derives the PHC). Also adapt the one caller from the ocelot psfp.sh test. In the case of psfp.sh, phc2sys_start is able to properly figure out that CLOCK_REALTIME is the source clock and swp1's PHC is the destination, because of the way in which ptp4l_start for the UDS_ADDRESS_SWP1 was called: with slave_only=false, so it will always win the BMCA and always become the sync master between itself and $h1.

Switch ports will want to act as Boundary Clocks, which are configured using ptp4l by specifying the "-i" argument multiple times. Since we track a log file and a pid file for each ptp4l instance, and we want to be compatible with the existing single-port callers of ptp4l_start and ptp4l_stop, pass the interface list as a single string of space-separated values. Based on this, we create a label for each ptp4l instance, where the spaces are replaced with underscores (ptp4l_start "eth0 eth1" generates "ptp4l_pid_eth0_eth1"). Signed-off-by:

Vladimir Oltean authored
The extra_args argument ($3) of isochron_recv_start is overwritten with uds ($2), if that argument exists. This is currently not a problem, because the only TSN selftest (ocelot/psfp.sh) omits remote sync so it does not specify to the receiver a UNIX domain socket for ptp4l. So $uds is currently an empty string. Signed-off-by:
