A general documentation about MPTCP was missing since its introduction in v5.6. Most of what is there comes from our recently updated mptcp.dev website, with additional links to resources from the kernel documentation. This is a first version, mainly targeting app developers and users. Link: https://www.mptcp.devReviewed-by:

Similar to what is done in other 'sysctl' pages: it looks clearer from a readability perspective. This might cause troubles in the short/mid-term with the backports, but by not putting new entries at the end, this can help to reduce conflicts in case of backports in the long term. We don't change the information here too often, so it looks OK to do that. Reviewed-by:

Russell King says: ==================== net: phylink: rearrange ovr_an_inband support This series addresses the use of the ovr_an_inband flag, which is used by two drivers to indicate to phylink that they wish to use inband mode without firmware specifying inband mode. The issue with ovr_an_inband is that it overrides not only PHY mode, but also fixed-link mode. Both of the drivers that set this flag contain code to detect when fixed-link mode will be used, and then either avoid setting it or explicitly clear the flag. This is wasteful when phylink already knows this. Therefore, the approach taken in this patch set is to replace the ovr_an_inband flag with a default_an_inband flag which means that phylink defaults to MLO_AN_INBAND instead of MLO_AN_PHY, and will allow that default to be overriden if firmware specifies a fixed-link. This allows users of ovr_an_inband to be simplified. What's more is this requires minimal changes in phylink to allow this new mode of operation. This series changes phylink, and also updates the two drivers (fman_memac and stmmac), and then removes the unnecessary complexity from the drivers. This series may depend on the stmmac cleanup series I've posted earlier - this is something I have not checked, but I currently have these patches on top of that series. ==================== Link: https://lore.kernel.org/r/ZlctinnTT8Xhemsm@shell.armlinux.org.ukSigned-off-by:

Of the two users of phylink_config->ovr_an_inband, both manually check for a fixed link before setting this flag (or clearing it if they find a fixed link.) This is unnecessary complication. Test ovr_an_inband before checking for the fixed-link properties, which will allow ovr_an_inband to be overriden by a fixed link specification. Signed-off-by:

Rearrange phylink_parse_mode() a little so we can change how phylink_config->ovr_an_inband works.

It is incorrect to call netif_carrier_off(), or in fact any driver teardown, before unregister_netdev() has been called. unregister_netdev() unpublishes the network device from userspace, and takes the interface down if it was up prior to returning. Therefore, once the call has returned, we are guaranteed that .ndo_stop() will have been called for an interface that was up. Phylink will take the carrier down via phylink_stop(), making any manipulation of the carrier in the remove path unnecessary. In the stmmac_release() path, the netif_carrier_off() call follows the call to phylink_stop(), so this call is redundant. Reviewed-by:

First of all the flags are never set by any of the driver parts. If nobody have them set then the respective statements will always have the same result. Thus the statements can be simplified or even dropped with no risk to break things. Secondly shall any of the TBI or RTBI flag is set the MDIO-bus registration will be bypassed. Why? It really seems weird. It's perfectly fine to have a TBI/RTBI-capable PHY configured over the MDIO bus interface. Based on the notes above the TBI/RTBI PCS flags can be freely dropped thus simplifying the driver code. Reviewed-by:

A comment in define_trace.h clearly states: TRACE_INCLUDE_PATH if the path is something other than core kernel vvvvvvvvvvvvvv include/trace then this macro can define the path to use. Note, the path is relative to define_trace.h, not the file including it. Full path names ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ for out of tree modules must be used. fjes uses path relative to itself. Which (somehow) works most of the time. Except when the kernel tree is "nested" in another kernel tree, and ../drivers/net/fjes actually exists. In which case build will use the header file from the wrong directory. I've been trying to figure out why net NIPA builder is constantly failing for the last 5 days, with: include/trace/../../../drivers/net/fjes/fjes_trace.h:88:17: error: ‘__assign_str’ undeclared (first use in this function) 88 | __assign_str(err, err); | ^~~~~~~~~~~~ when the line in the tree clearly has only one "err". NIPA does indeed have "nested" trees, because it uses git work-trees and the tree on the "outside" is not very up to date.

Joe Damato says: ==================== mlx4: Add support for netdev-genl API There are no functional changes from v5, which I mistakenly sent right after net-next was closed (oops). This revision, however, includes Tariq's Reviewed-by tags of the v5 in each commit message. See the changelog below. This series adds support to mlx4 for the netdev-genl API which makes it much easier for users and user programs to map NAPI IDs back to ifindexes, queues, and IRQs. This is extremely useful for a number of use cases, including epoll-based busy poll. In addition, this series includes a patch to generate per-queue statistics using the netlink API, as well. To facilitate the stats, patch 1/3 adds a field "alloc_fail" to the ring structure. This is incremented by the driver in an appropriate place and used in patch 3/3 as alloc_fail. Please note: I do not have access to mlx4 hardware, but I've been working closely with Martin Karsten from University of Waterloo (CC'd) who has very graciously tested my patches on their mlx4 hardware (hence his Tested-by attribution in each commit). His latest research work is particularly interesting [1] and this series helps to support that (and future) work. Martin re-test v4 using Jakub's suggested tool [2] and the stats.pkt_byte_sum and stats.qstat_by_ifindex tests passed. He also adjusted the queue count and re-ran test to confirm it still passed even if the queue count was modified.
