https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D254201 Bug ID: 254201 Summary: ptrace(): rfork(RFSPAWN) / posix_spawn() reports fork instead of vfork (+ vfork_done) Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: mgorny@gentoo.org CC: emaste@freebsd.org, mhorne@freebsd.org Created attachment 223168 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D223168&action= =3Dedit reproducer If the debugged program executes rfork(RFSPAWN) or posix_spawn(), the first SIGTRAP signal reports PL_FLAG_FORKED instead of PL_FLAG_VFORKED. This is followed by PL_FLAG_VFORK_DONE, so I guess PL_FLAG_VFORKED was desired. I'm attaching a simple reproducer. Confirmed on 14.0-CURRENT from end of January. --=20 You are receiving this mail because: You are the assignee for the bug.=
