https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221317 --- Comment #43 from commit-hook@freebsd.org --- A commit references this bug: Author: marius Date: Wed Feb 13 15:19:32 UTC 2019 New revision: 344100 URL: https://svnweb.freebsd.org/changeset/base/344100 Log: MFC: r343621 ix(4): Run {mod,msf,mbx,fdir,phy}_task in if_update_admin_status From Piotr: This patch introduces adapter->task_requests register responsible for recording requests for mod_task, msf_task, mbx_task, fdir_task and phy_task calls. Instead of enqueueing these tasks with GROUPTASK_ENQUEUE, handlers will be called directly from ixgbe_if_update_admin_status() while holding ctx lock. SIOCGIFXMEDIA ioctl() call reads adapter->media list. The list is deleted and rewritten in ixgbe_handle_msf() task without holding ctx lock. This change is needed to maintain data coherency when sharing adapter info via ioctl() calls. Patch co-authored by Krzysztof Galazka <krzysztof.galazka@intel.com>.
