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.

The intention is to reuse "port" in place of "slave" in the bonding driver
after making this change, as port is consistent with the bridge and team
drivers, and allows us to remove socially problematic language from the
bonding driver.

Use "port" to denote individual component interfaces in a bond, rather
than "slave". This is more consistent with the team and bridge drivers,
and eliminates the use of a good amount of problematic language in the
bonding driver.
Legacy sysfs, procfs and module parameter bits that use slave in their
names are retained for the purposes of not breaking anyone's userspace.
The /proc/net/bonding/<bond> output simply duplicates output information
on otherwise identical "Port" and "Slave" lines.

Point users to the new interface names instead of the old ones, where
appropriate. Userspace bits referenced still include use of master/slave,
but those can't be altered until userspace changes too, ideally after
these changes propagate to the community at large.

Hi Jarod
It is going to take quite a while before all distributions user space
gets updated. So todays API is going to live on for a few
years. People are going to be search the documentation using the terms
their user space uses, which are going to be todays terms, not the new
ones you are introducing here. For that to work, i think you are going
to have to introduce a table listing todays names and the new names
you are adding, so search engines have some chance of finding this
document, and readers have some clue as to how to translate from what
their user space is using to the terms used in the document.

You can change internal variable names, comments, and documentation all you want, thats great.
But you can't change user API, that includes:

This is problematic. You are printing both old and new values.
Also every distribution will have to enable it.
This looks like too much of change to users.

All of those are retained by default here in this set. There are 0
changes to the if_bonding.h uapi header, module parameters with 'port'
in them have duplicates with the old terminology included, and all
sysfs file names are duplicated (or aliased) as well. The
documentation was updated to point to the new names, but the old ones
still exist across the board, there should be no userspace breakage
here. (My lnst bonding tests actually fall flat currently if the old
names are gone).

Hm. Would a simple blurb describing the when the changes were made and
why at the top of bonding.rst be sufficient? And then would the rest
of the doc remain as-is (old master/slave language), or with
terminology conversions?

I'd had a bit of feedback that people would rather see both, and be
able to toggle off the old ones, rather than only having one or the
other, depending on the toggle, so I thought I'd give this a try. I
kind of liked the one or the other route, but I see the problems with
that too.
For simplicity, I'm kind of liking the idea of just not updating the
proc and sysfs interfaces, have a toggle entirely disable them, and
work on enhancing userspace to only use netlink, but ... it's going to
be a while before any such work makes its way to any already shipping
distros. I don't have a satisfying answer here.

I'm assuming you want to deprecate the old language? So i was
expecting the language to change. I would expect some explanation of
why the names have changed, and a table listing the old and new name.
We cannot completely get away from the old names, because they are
ABI, so we need to keep documenting them somehow.

I like the idea of having bonding proc and sysf apis optional.

Agreed, no Kconfig knob.
Keep everything during the deprecation period, then you can kill off
the old names at the end of the deprecation period.
I don't want to create a situation where distribution X lists as a
"feature" that they are able to enable this Kconfig value even though
it breaks UAPI for legacy external code out there.
That's the wrong way to go about this and creates the wrong incentive
system.
I also agree that you can't change the docs to stop mentioning the old
names. It's almost like we are pretending we aren't doing the
transition and that only the new names matter. The old names matter
and must therefore be acknowledged, exist, and be referencable in the
documentation until the end of the deprecation period. You can mark
them "(DEPRECATED)" or similar, but they can't be removed just yet.
Thank you.

The documentation is the reference point for people reading code in
userspace that manipulates bonding devices.
So people will come across the deprecated names in userland code and
therefore will try to learn what they do and what they mean.
Which means that the documentation must reference the old names.
You can mark them "(DEPRECATED)" or similar, but you must not remove
them.

Please keep everything for the entire deprecation period, unconditionally.

Okay, so it sounds like just a blurb near the top of the file
referencing the changes that have been made in the code might be the
way to go here. Tagging every occurrence of master or slave in the doc
inline as deprecated would get ... noisy.

Okay, so 100% drop the Kconfig flag patch, but duplicate sysfs
interface names are acceptable, correct? Then what about the procfs
file having duplicate Slave and Port lines? Just leave them all as
Slave?

I do too, but I'd see it more as something only userspace developers
would care about for a while, as an easy way to make absolutely
certain their code/distro is no longer reliant on them and only uses
netlink, not as something any normal user really has any reason to do.

My preference is to not alter the existing sysfs / proc behavior
at all, and instead create a netlink / iproute UAPI that becomes the
"preferred" UAPI going forward. Any new functionality would only be
added to netlink as incentive to switch.
I don't see the value in adding duplicate fields, as userspace
code that parses them will not be portable if it only checks for the new
field name. Then, down the road, deleting the old names will break the
userspace code that was never updated (which will likely be most of it).
I would rather see a single clean break from proc and sysfs to
netlink in one step than a piecemeal addition and removal from the
existing UAPI. That makes for a much clearer flag day event for end
users. By this I mean leave proc / sysfs as-is today, and then after a
suitable deprecation period, remove it wholesale (rather than a compile
time option).
