https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202482 Bug ID: 202482 Summary: [patch] [regression] mbuf(9): m_unshare() drops m_pkthdr after r248371 Product: Base System Version: 11.0-CURRENT Hardware: Any OS: Any Status: New Keywords: patch, regression Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: s3erios@gmail.com Keywords: patch, regression Created attachment 160103 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=160103&action=edit Reverse patch for r248371 This change causes kernel panics on some configurations. How-to-reproduce: Add a wireless card without hardware encryption into a bridge. While sending a packet, m_unshare() in ieee80211_mbuf_adjust() will discard m->m_pkthdr.rcvif after it was initialized in the ieee80211_vap_pkt_send_dest() (mbuf must be marked as read-only). The patch reverts this commit. -- You are receiving this mail because: You are the assignee for the bug.
