https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259625 --- Comment #7 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Konstantin Belousov from comment #5) I remembered that there is a trick in POSIX that de-facto allowed O_RDONLY be zero. But apparently it is even more strict, making your second program non-conforming. Applications shall specify exactly one of the first five values (file access modes) below in the value of oflag: O_EXEC Open for execute only (non-directory files). The result is unspecified if this flag is applied to a directory. O_RDONLY Open for reading only. O_RDWR Open for reading and writing. The result is undefined if this flag is applied to a FIFO. O_SEARCH Open directory for search only. The result is unspecified if this flag is applied to a non-directory file. O_WRONLY Open for writing only. I.e. O_RDONLY|O_EXEC is illegal from POSIX PoV, and FreeBSD interprets it as O_EXEC. -- You are receiving this mail because: You are the assignee for the bug.home | help
