https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=238837 Bug ID: 238837 Summary: Remove P_SYSTEM flag from PID 1 to allow easier debugging of init(8) Product: Base System Version: 11.3-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: msl0000023508@gmail.com Created attachment 205367 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=205367&action=edit allow-ptrace-attach-1.diff Currently ptrace(2) won't allow attaching to processes have P_SYSTEM flag set; by removing this flag, debuggers like gdb(1) and lldb(1) will be able to debug the current running init(8) process like other userspace processes. Like all programs, init(8) may need to be ptrace(2)-attached, due to bugs or testing new changes; generally, allowing that would be very convenient when working with init(8)-related debuggings. Although I currently didn't have a need to debug the FreeBSD init(8), this report was a generic idea open for discuss. -- You are receiving this mail because: You are the assignee for the bug.
