Hi, this patch adds extack support for TC classifier subsystem. The first patch fixes some code style issues for this patch series pointed out by checkpatch. The other patches until the last one prepares extack handling for the TC classifier subsystem and handle generic extack errors.
The last patch is an example for u32 classifier to add extack support inside the callbacks delete and change. There exists a init callback as well, but most classifier implementation run a kalloc() once to allocate something. Not necessary _yet_ to add extack support now. I know there are patches around which makes changes to these files. I will rebase my stuff on Jiri's patches if they get in before mine. - Alex Cc: David Ahern <dsah...@gmail.com> Alexander Aring (8): net: sched: cls: fix code style issues net: sched: cls_api: handle generic cls errors net: sched: cls: add extack support for change callback net: sched: cls: add extack support for tcf_exts_validate net: sched: cls: add extack support for delete callback net: sched: cls: add extack support for tcf_change_indev net: sched: cls: add extack support for tc_setup_cb_call net: sched: cls_u32: add extack support include/net/pkt_cls.h | 13 ++++-- include/net/sch_generic.h | 7 +++- net/sched/cls_api.c | 74 +++++++++++++++++++++++++-------- net/sched/cls_basic.c | 14 ++++--- net/sched/cls_bpf.c | 32 ++++++++------ net/sched/cls_cgroup.c | 9 ++-- net/sched/cls_flow.c | 8 ++-- net/sched/cls_flower.c | 31 ++++++++------ net/sched/cls_fw.c | 17 ++++---- net/sched/cls_matchall.c | 24 +++++++---- net/sched/cls_route.c | 12 +++--- net/sched/cls_rsvp.h | 7 ++-- net/sched/cls_tcindex.c | 14 ++++--- net/sched/cls_u32.c | 104 ++++++++++++++++++++++++++++++++-------------- 14 files changed, 243 insertions(+), 123 deletions(-) -- 2.11.0
