The bonding driver's use of master and slave, while largely understood in technical circles, poses a barrier for inclusion to some potential members of the development and user community, due to the historical context of masters and slaves, particularly in the United States. This is a first full pass at replacing those phrases with more socially inclusive ones, opting for bond to replace master and port to replace slave, which is congruent with the bridge and team drivers.
There are a few problems with this change. First up, "port" is used in the bonding 802.3ad code, so the first step here is to rename port to ad_port, so we can reuse port. Second, we have the issue of not wanting to break any existing userspace, which I believe this patchset accomplishes, while also adding alternate interfaces using the new terminology. This set also includes a Kconfig option that will let people make the conscious decision to break userspace and no longer expose the original master/slave interfaces, once their userspace is able to cope with their removal. Lastly, we do still have the issue of ease of backporting fixes to -stable trees. I've not had a huge amount of time to spend on it, but brief forays into coccinelle didn't really pay off (since it's meant to operate on code, not patches), and the best solution I can come up with is providing a shell script someone could run over git-format-patch output before git-am'ing the result to a -stable tree, though scripting these changes in the first place turned out to be not the best thing to do anyway, due to subtle cases where use of master or slave can NOT yet be replaced, so a large amount of work was done by hand, inspection, trial and error, which is why this set is a lot longer in coming than I'd originally hoped. I don't expect -stable backports to be horrible to figure out one way or another though, and I don't believe that a bit of inconvenience on that front is enough to warrant not making these changes. See here for further details on Red Hat's commitment to this work: https://www.redhat.com/en/blog/making-open-source-more-inclusive-eradicating-problematic-language As far as testing goes, I've manually operated on various bonds while working on this code, and have run it through multiple lnst test runs, which exercises the existing sysfs interfaces fairly extensively. As far as I can tell, there is no breakage of existing interfaces with this set, unless the user consciously opts to do so via Kconfig. v2: legacy module parameters are retained this time, and we're trying out bond/port instead of aggregator/link in place of master/slave. The procfs interface legacy output is also duplicated or dropped, depending on Kconfig, rather than being replaced.
