![]() Since all the platforms now support O_DIRECTORY flag for open, it can be used to (together with O_NOFOLLOW) to ensure we open a directory, thus eliminating the need to call stat before open. This fixes the symlink race, when a directory is replaced by a symlink in between stat and open calls. While at it, rename openFdAt to openDirAt, because this function is (and was) meant for directories only. NOTE Solaris supports O_DIRECTORY since before Solaris 11 (which is the only version Go supports since supported version now), and Illumos always had it. The only missing piece was O_DIRECTORY flag value, which is taken from golang.org/x/sys/unix. Updates #52745.
