https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D259625 --- Comment #5 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Drew DeVault from comment #4) This example might be surprising initially, but it is not. Issue is that O_RDONLY is zero, so O_EXEC | O_RDONLY =3D=3D O_EXEC. Then, when you try t= o open fdescfd node, it checks for READ permission (since O_RDONLY is zero and no permissions implies READ), but sees that fd is opened for EXEC only. --=20 You are receiving this mail because: You are the assignee for the bug.=
