Ophestra	e47aebb7a0	internal/app/outcome: apply configured filesystems late ... This enables configured filesystems to cover system mount points. Closes #8. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-19 01:41:52 +09:00
Ophestra	9e48d7f562	hst/config: move container fields from toplevel ... This change also moves pd behaviour to cmd/hakurei, as this does not belong in the hst API. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-07 04:24:45 +09:00
Ophestra	f280994957	internal/app: check nscd socket for path hiding ... This can seriously break things, and exposes extra host attack surface, so include it here. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-05 20:47:30 +09:00
Ophestra	83c4f8b767	test/sandbox: check extra writable paths ... This is not always obvious from mountinfo. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-09-14 15:12:51 +09:00
Ophestra	ca247b8037	internal/app: mount /dev/shm early ... This avoids covering /dev/shm mounts from hst. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-09-14 01:49:42 +09:00
Ophestra	9bc8532d56	container/initdev: mount tmpfs on shm for ro dev ... Programs expect /dev/shm to be a writable tmpfs. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-08-26 03:27:07 +09:00
Ophestra	4cf694d2b3	hst: use hsu userid for share path suffix ... The privileged user is identifier to hakurei through its hsu userid. Using the kernel uid here makes little sense and is a leftover design choice from before hsu was implemented. Closes #7. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-08-26 02:16:33 +09:00
Ophestra	c9facb746b	hst/config: remove data field, rename dir to home ... There is no reason to give the home directory special treatment, as this behaviour can be quite confusing. The home directory also does not necessarily require its own mount point, it could be provided by a parent or simply be ephemeral. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-08-26 00:56:10 +09:00
Ophestra	0dcac55a0c	hst/config: remove container etc field ... This no longer needs special treatment since it can be specified as a generic filesystem entry. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-08-25 19:24:33 +09:00
Clayton Gilmer	5db0714072	container: optionally isolate host abstract UNIX domain sockets via landlock	2025-08-18 16:28:14 +09:00
Ophestra	38245559dc	container/ops: mount dev readonly ... There is usually no good reason to write to /dev. This however doesn't work in internal/app because FilesystemConfig supplied by ContainerConfig might add entries to /dev, so internal/app follows DevWritable with Remount instead.

Ophestra	3b8a3d3b00	app: remount root readonly ... This does nothing for security, but should help avoid hiding bugs of programs developed in a hakurei container. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-08-01 23:56:28 +09:00
Ophestra	af0899de96	hst/container: mount tmpfs via magic src string ... There's often good reason to mount tmpfs in the container. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-08-01 21:23:52 +09:00
Ophestra	547a2adaa4	container/mount: pass tmpfs flags ... Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-08-01 18:59:06 +09:00
Ophestra	387b86bcdd	app: integrate container autoroot ... Doing this instead of mounting directly on / because it's impossible to ensure a parent is available for every path hakurei wants to mount to. This situation is similar to autoetc hence the similar name, however a symlink mirror will not work in this case. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-08-01 04:21:54 +09:00
