jochen	7320d99a11	Make nfs-server reconcile the kernel's exports with its file, so a failed reload or a withdrawn grant is not left exported while the module says it is healthy; warn on a stale or unknown backup list	2026-10-09 14:43:32 +02:00
jochen	72a6d062dc	Let SIGTERM cancel a running pass and bound nfs-server's clean-up at 10 s, so a hanging command cannot keep the export file past the stop timeout	2026-10-09 14:43:32 +02:00
jochen	87d6a5549c	Check every share against where the backup seat keeps its data on every pass, so the hour a clean look is believed cannot hide a new repository	2026-10-09 14:43:32 +02:00
jochen	29ac6ee16a	Say that the modules' own checks are the only line before root, since sudo grants the account everything	2026-10-08 20:21:28 +02:00
jochen	8738c02d00	nfs-server: export a share only to the nodes granted and wanting it, and never root's, a symlinked or nested backup, or an unmounted dataset ... The review of #136 found a share could squash every client to root, be judged at a symlink's name rather than its folder, sit inside or above a backup repository deeper than one level, export an unmounted dataset's empty folder, go to every address in the private network's range, and stay exported after the module left. Each is now refused or closed, with a test that reproduced it first: - a folder owned by uid or gid 0 is refused; - the path is resolved through symlinks and every check runs on the real folder, which the export line names; - a share inside a backup repository (any parent) or holding one within four levels is refused, and a look cut short by its bound refuses; - every line carries mp, or mp=<its filesystem's mount point>; - a share goes only to the nodes this machine's grants setting names and whose mounts module wants it on the bus, at the lower access, at the roster's address inside the range; nothing without wants; - the process is declared before its config, so on unassignment it finds the config gone, removes its export file and lets the shares go; - confirm accepts the seat's string "true".	2026-10-08 20:20:05 +02:00
