John Safranek d43eb01a66 sftp: refuse dir REMOVE and replacing RENAME ... SSH_FXP_REMOVE does not take directories and SSH_FXP_RENAME fails on an existing newpath (draft-ietf-secsh-filexfer-02 6.5). The non-Windows handlers check with an lstat first, oldpath before newpath, and REMOVE unlinks. A regular file renames by linkat() and unlink(), which refuses an existing name atomically; anything else checks then calls rename(). - configure: probe for linkat() - port.h: WUNLINK on POSIX, WLINK as linkat() when configure finds it - FatFs, Nucleus: only "/" and "/." stand in for the root - regress: test both against files, directories, symlinks and a read-only directory Issue: F-15535, F-15536		2026-11-02 13:40:06 -06:00
