2025-08-20container/capability: check CAP_TO_INDEX and CAP_TO_MASKOphestra
Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-20container/autoetc: do not bypass absolute checkOphestra
This can now be done cleanly via path function wrappers. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-20container/initmkdir: check path equivalence by valueOphestra
Fixes regression introduced while integrating Absolute. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-20container/initbind: check path equivalence by valueOphestra
Same problem as autoroot, never updated the checks after integrating Absolute. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-20container/autoroot: check host path equivalence by valueOphestra
This will never return true otherwise unless the equivalent paths happen to be interned by the caller. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-20container/init: split setup ops into individual filesOphestra
This significantly increases readability. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-20container/ops: move Op type to init fileOphestra
This helps with the eventual separation of all setup ops into individual files. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-20container/autoroot: filter dentry with empty nameOphestra
This is unreachable, but nice to have just in case. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-20container: ptrace protection via Yama LSMOphestra
This is only a nice to have feature as the init process has no additional privileges and the monitor process was never reachable anyway. Closes #4. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-19system/dbus/proc: host abstract only when not bindingOphestra
The test failure seems to be caused by an unrelated bug in xdg-dbus-proxy. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-18container/params: check setup/receive behaviourOphestra
Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-18container/path: check create and mountinfo helpersOphestra
These can quite easily be checked within the framework. The scanner fault injection might require updating at some point if the implementation changes. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-18cmd/hpkg: add deprecation noticeOphestra
Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-18hst: rename net and abstract fieldsOphestra
This makes more sense and matches the container library. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-18container: optionally isolate host abstract UNIX domain sockets via landlockClayton Gilmer
2025-08-18container: move PR_SET_NO_NEW_PRIVS to parentOphestra
This allows some LSM setup in the parent. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-18test/sandbox: do not discard stderr getting hashOphestra
This is the first hakurei run in the test, if the container outright fails to start this is often where it happens, so throwing away the output is very unhelpful. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-18app: set up acl on X11 socketOphestra
The socket is typically owned by the priv-user, and inaccessible by the target user, so just allowing access to the directory is not enough. This change fixes this oversight and add checks that will also be useful for merging https://git.gensokyo.uk/security/hakurei/pulls/1. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-17container: start from locked threadOphestra
This allows setup that relies on per-thread state like securebits and landlock, from the parent side. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-17container: check output helper functionsOphestra
The container test suite has always been somewhat inadequate due to the inability of coverage tooling to reach into containers. This has become an excuse for not testing non-container code as well, which lead to the general lack of confidence when working with container code. This change aims to be one of many to address that to some extent. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-17container: enforce nonrepeatable autoetc and autorootOphestra
These keep track of some internal state, and they don't make sense to have multiple instances of anyway, so instead of dealing with that, just make them nonrepetable. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-17container: allow additional state between opsOphestra
This is useful for ops that need to be aware of previous instances of themselves. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-16hst: merge miscellaneous filesOphestra
These structs were going to be bigger at some point. They turned out not to be. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-16hst: move container type to configOphestra
Container state initialisation is no longer implemented in hst so splitting them no longer makes sense. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-16hst/fs: rename method Target to PathOphestra
This allows adapter structs to use the same field names as Op structs. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-15hst/enablement: editor friendly enablement adaptorOphestra
Having the bit field value here (in decimal, no less) is unfriendly to text editors. Use a bunch of booleans here to improve ease of use. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-15hst/fs: implement overlay fstypeOphestra
This finally exposes overlay mounts in the high level hakurei API. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-15nix: check config via hakureiOphestra
This is unfortunately the only feasible way of doing this in nix. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-15hst/fs: remove type methodOphestra
Having a method that returns the canonical string representation of its type seemed like a much better idea for an implementation that never made it to staging. Remove it here and clean up marshal type assertions. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-14container: export overlay escapeOphestra
Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-14hst/fs: valid method on underlying interfaceOphestra
Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-14hst/info: include extra informationOphestra
Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-14container/path: remove unused pathOphestra
Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-14hst/fs: interface filesystem configOphestra
This allows mount points to be represented by different underlying structs. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-11container: use absolute for pathnameOphestra
This is simultaneously more efficient and less error-prone. This change caused minor API changes in multiple other packages. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-10container/absolute: wrap safe stdlib functionsOphestra
These functions do not change the absoluteness of a pathname. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-09container: remove PATH lookup behaviourOphestra
This is way higher level than the container package and does not even work unless every path is mounted in the exact same location. This behaviour causes nothing but confusion and problems, Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-09container/absolute: early absolute pathname checkOphestra
This is less error-prone, and allows pathname to be checked once. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-09container/params: remove confusingly named errorOphestra
Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-08container: document ambient capabilitiesOphestra
Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-08container/ops: implement overlay opOphestra
There are significant limitations to using the overlay mount, and the implementation in the kernel is quite quirky. For now the Op is quite robust, however a higher level interface for it has not been decided yet. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-08container/path: fix typo "paths"Ophestra
Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-08container: test case runtime initialisationOphestra
This allows for more sophisticated test setup. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-08container: test bypass output buffer on verboseOphestra
This restores verbose behaviour. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-08test/interactive: helper scripts for tracingOphestra
The vm state is discarded often, and it is quite cumbersome to set everything up again when the shell history is gone. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-08container: raise CAP_DAC_OVERRIDEOphestra
This is required for upperdir and workdir checks in overlayfs. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-07nix: make src overlay writableOphestra
The lowerdir is in the nix store. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-07container: buffer test outputOphestra
This further reduces noise on test failure by only passing through output of the failed test. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-07container: test respect verbose flagOphestra
This reduces noise on test failure. Signed-off-by: Ophestra <cat@gensokyo.uk>
2025-08-07nix: interactive nixos vmOphestra
This is useful for quickly spinning up an ephemeral hakurei environment for testing changes or reproducing vm test failures. Signed-off-by: Ophestra <cat@gensokyo.uk>
