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. - Alex Cc: David Ahern <dsah...@gmail.com> changes since v3: - fix accidentally move of config option mismatch message in PATCH 2/8 correct one is 4/8, detected by kbuildbot (Thank you) - Removed patch "net: sched: cls: add extack support for tc_setup_cb_call" PATCH 7/8 in version v2 as suggested by Jakub Kicinski (Thank you) - changed NL_SET_ERR_MSG to NL_SET_ERR_MSG_MOD as suggested by Jakub Kicinski in u32 cls (Thank You) - Removed text from cover letter that I was waiting for Jiri's Patches as detected by Jamal Hadi Salim (Thank you). changes since v2: - rebased on Jiri's patches (Thank you) - several spelling fixes pointed out by Cong Wang (Thank you) - several spelling fixes pointed out by David Ahern (Thank you) - use David Ahern recommendation if config option is mismatch, but combine it with Cong Wang recommendation to put config name into it (Thank you) Alexander Aring (7): 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_u32: add extack support include/net/pkt_cls.h | 10 +++++-- include/net/sch_generic.h | 7 +++-- net/sched/cls_api.c | 64 +++++++++++++++++++++++++++++---------- net/sched/cls_basic.c | 14 +++++---- net/sched/cls_bpf.c | 13 ++++---- net/sched/cls_cgroup.c | 9 ++++-- net/sched/cls_flow.c | 8 +++-- net/sched/cls_flower.c | 20 ++++++++----- net/sched/cls_fw.c | 17 ++++++----- net/sched/cls_matchall.c | 15 ++++++---- net/sched/cls_route.c | 12 ++++---- net/sched/cls_rsvp.h | 7 +++-- net/sched/cls_tcindex.c | 14 +++++---- net/sched/cls_u32.c | 76 ++++++++++++++++++++++++++++++++++------------- 14 files changed, 194 insertions(+), 92 deletions(-) -- 2.11.0
