2024-11-18app: alternative inner home pathOphestra Umiker
Support binding home to an alternative path in the mount namespace. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>
2024-11-16app: integrate fsuOphestra Umiker
This removes the dependency on external user switchers like sudo/machinectl and decouples fortify user ids from the passwd database. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>
2024-11-04app: support mapping target uid as privileged uid in sandboxOphestra Umiker
Chromium's D-Bus client implementation refuses to work when its getuid call returns a different value than what the D-Bus server is running as. The reason behind this is not fully understood, but this workaround is implemented to support chromium and electron apps. This is not used by default since it has many side effects that break many other programs, like SSH on NixOS. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>
2024-11-04app: format mapped uid instead of real uidOphestra Umiker
Signed-off-by: Ophestra Umiker <cat@ophivana.moe>
2024-11-02cmd: shim and init into separate binariesOphestra Umiker
This change also fixes a deadlock when shim fails to connect and complete the setup. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>
2024-10-23internal: wrap calls to os standard library functionsOphestra Umiker
This change helps tests stub out and simulate OS behaviour during the sealing process. This also removes dependency on XDG_RUNTIME_DIR as the internal.System implementation provided to App provides a compat directory inside the tmpdir-based share when XDG_RUNTIME_DIR is unavailable.

2024-10-20app: move app ID to app structOphestra Umiker
App ID is inherent to App, and it makes no sense to generate it as part of the app sealing process. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>
2024-10-18app/share: fix order to ensure SharePath before any of its subdirectoriesOphestra Umiker
shareTmpdirChild happened to request an ephemeral dir within SharePath and was called before shareRuntime which ensures that path. This commit moves SharePath initialisation to shareSystem and moves shareTmpdirChild into ShareSystem. Further cleanup and tests are desperately needed for the app package but for now this fix will have to do. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>
2024-10-16app: port app to use the system packageOphestra Umiker
This commit does away with almost all baggage left over from the Ego port. Error wrapping also got simplified. All API changes happens to be internal which means no changes to main except renaming of the BaseError type. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>
2024-10-15helper/bwrap: ordered filesystem argsOphestra Umiker
The argument builder was written based on the incorrect assumption that bwrap arguments are unordered. The argument builder is replaced in this commit to correct that mistake. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>
2024-10-13app: generate and replace passwd and group filesOphestra Umiker
This ensures libc functions get correct user information. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>
