Perform pseudo-filesystem permission checks inside inode_reserve() and inode_remove() while the inode tree lock is held, and hold that lock across pseudorename mutations so symlink swaps cannot bypass directory checks. Hold a read lock around pseudo-fs open permission checks. On setuid/setgid exec, update saved set-IDs, mark the task group secure, sanitize dangerous environment variables, clear debug/dumpable flags, and add issetugid(), secure_getenv(), and PR_SET/GET_DUMPABLE support.
