The MAC filter set may be called without softc_lock held in the case of SIOCADDMULTI and SIOCDELMULTI ioctls. The ioctl handler checks IFF_DRV_RUNNING flag which implies port started, but it is not guaranteed to remain. softc_lock shared lock can't be held in the case of these ioctls processing, since it results in failure where kernel complains that non-sleepable lock is held in sleeping thread. Both problems are repeatable on LAG with LACP proto bring up. Submitted by: Andrew Rybchenko <Andrew.Rybchenko at oktetlabs.ru> Sponsored by: Solarflare Communications, Inc. MFC after: 2 weeks |
