The branch stable/13 has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=745bba174efe9f6bb4efbeb9643046acd0f6f732 commit 745bba174efe9f6bb4efbeb9643046acd0f6f732 Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2023-10-03 21:14:55 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2023-11-29 16:36:10 +0000 LinuxKPI: 802.11: fix re-creation of VAP After dbf7691999abe (as indicated in that commit message) EEXISTS errors may be seen. From current investigation that is due to the single-VAP support in LinuxKPI 802.11 and the related calls to mo_start() and mo_stop() and them being disabled in ic_parent() currently. Calling mo_stop() in lkpi_ic_vap_delete() seems to fix the problem and new VAPs (wlan interfaces) can be created again after being destroyed. Fixes: dbf7691999abe ("improve lkpi_ic_vap_delete()") Sponsored by: The FreeBSD Foundation (cherry picked from commit 6c38c6b1b917957d420902213f318bf0153214f2) --- sys/compat/linuxkpi/common/src/linux_80211.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/sys/compat/linuxkpi/common/src/linux_80211.c b/sys/compat/linuxkpi/common/src/linux_80211.c index 85965493e5ef..0a673a313c1e 100644 --- a/sys/compat/linuxkpi/common/src/linux_80211.c +++ b/sys/compat/linuxkpi/common/src/linux_80211.c @@ -2481,6 +2481,9 @@ lkpi_ic_vap_delete(struct ieee80211vap *vap) lkpi_80211_mo_remove_interface(hw, vif); + /* Single VAP, so we can do this here. */ + lkpi_80211_mo_stop(hw); + mtx_destroy(&lvif->mtx); free(lvif, M_80211_VAP); }
