[net-next,v3,0/4] net/sched: act_pedit: minor improvements

Message

Pedro Tammela March 17, 2023, 7:51 p.m. UTC

This series aims to improve the code and usability of act_pedit for
netlink users.

Patch 1 improves error reporting for extended keys parsing with extack.
While at it, do a minor refactor on error handling.

Patch 2 checks the static offsets a priori on create/update. Currently,
this is done at the datapath for both static and runtime offsets.

Patch 3 removes a check from the datapath which is redundant since the
netlink parsing validates the key types.

Patch 4 changes the 'pr_info()' calls in the datapath to rate limited
versions.

v2->v3: Propagate nl_parse errors in patch 1 like the original version.
v1->v2: Added patch 3 to the series as discussed with Simon.

Pedro Tammela (4):
  net/sched: act_pedit: use extack in 'ex' parsing errors
  net/sched: act_pedit: check static offsets a priori
  net/sched: act_pedit: remove extra check for key type
  net/sched: act_pedit: rate limit datapath messages
