[PATCH net-next 0/5] net/sched: Remove UAPI support for retired TC qdiscs and classifiers

[PATCH net-next 0/5] net/sched: Remove UAPI support for retired TC qdiscs and classifiers

[Jamal Hadi Salim]

Classifiers RSVP and tcindex as well as qdiscs dsmark, CBQ and ATM have already
been deleted. This patchset removes their UAPI support.

User space - with a focus on iproute2 - typically copies these UAPI headers for
different kernels.
These deletion patches are coordinated with the iproute2 maintainers to make
sure that they delete any user space code referencing removed objects at their
leisure.

[PATCH net-next 1/5] net/sched: Remove uapi support for rsvp classifier

[Jamal Hadi Salim]

commit 265b4da82dbf ("net/sched: Retire rsvp classifier") retired the TC RSVP
classifier.
Remove UAPI for it. Iproute2 will sync by equally removing it from user space.

Seems like a mistake for kernel source tree to include two copies of same file.
Shouldn't there be an automated make rule to update?

Probably there is - but if you pull a fresh net-next those files are
present in both those two dirs, so it seemed rational to patch both.

It is intentional, based on the initial commit which created this file:

commit 49a249c387268882e8393dd1fafc51e3b21cb7a2
Author: Yonghong Song <yhs@fb.com>
Date:   Wed Nov 7 19:55:36 2018 -0800

    tools/bpftool: copy a few net uapi headers to tools directory

    Commit f6f3bac08ff9 ("tools/bpf: bpftool: add net support")
    added certain networking support to bpftool.
    The implementation relies on a relatively recent uapi header file
    linux/tc_act/tc_bpf.h on the host which contains the marco
    definition of TCA_ACT_BPF_ID.

    Unfortunately, this is not the case for all distributions.
    See the email message below where rhel-7.2 does not have
    an up-to-date linux/tc_act/tc_bpf.h.
      https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1799211.html
    Further investigation found that linux/pkt_cls.h is also needed for macro
    TCA_BPF_TAG.

    This patch fixed the issue by copying linux/tc_act/tc_bpf.h
    and linux/pkt_cls.h from kernel include/uapi directory to
    tools/include/uapi directory so building the bpftool does not depend
    on host system for these files.
