https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235239 Bug ID: 235239 Summary: [devd.conf] syntax broken by base r343249 Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: freebsd@oldach.net base r343249 changed the "subsystem" match case of a notify statement in order to fix bug #153594. Unfortunately the regex presented there is broken. "(?!usbus[0-9]+|?!wlan[0-9]+)" is not proper regex syntax - at minimum the question marks are wrong. Further, devd.cc implements a special handling of the negation case (first regex character is a '!'). See the match::match function in devd.cc starting at line 289. According to this logic (which BTW matches with the devd.conf manpage), it is imperative that the exclamation mark must be the first character. Hence the correct regex for implementing the effect intended by base r343249 would be: "!(usbus|wlan)[0-9]+" -- You are receiving this mail because: You are the assignee for the bug.help
