* Editorial improvements on fs-mistrust errorsNick Mathewson2022-06-221-0/+1
| | | | | | These changes make sure that the errors conform to our preferred style, and include a description of what exactly we were doing when something went wrong.

* Semantic version changes for Arti 0.4.0 releaseNick Mathewson2022-05-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | I followed the following procedure to make these changes: * I used maint/changed_crates to find out which crates had changed since 0.3.0. * I used grep and maint/list_crates to sort those crates in topological (dependency) order. * I looked through semver_status to find which crates were listed as having semver-relevant changes (new APIs and breaking changes). * I scanned through the git logs of the crates with no semver-relevant changes listed to confirm that, indeed, they had no changes. For those crates, I incremented their patch-level version _without_ changing the version that other crates depend on. * I scanned through the git logs of the crates with no semver-relevant changes listed to confirm that, indeed, they had no obvious breaking changes. * I treated all crates that depend on `arti` and/or `arti-client` as having breaking changes. * I identified crates that depend on crates that have changed, even if they have not changed themselves, and identified them as having a non-breaking change. * For all of the crates, I used `cargo set-version -p $CRATE --bump $STATUS` (where `STATUS` is `patch` or `minor`) to update the versions, and the depended-upon versions.
* Write custom serde impls for Trusted{User,Group}Nick Mathewson2022-05-241-1/+2
| | | | | | | | | | | | | | | | We support all of the following (in TOML notation): ``` user = "rose" # by name user = 413 # by ID user = false # no user user = ":current" # A 'special' user. user = { name: "rose" } user = { id: 413 } user = { special: ":none" } user = { special: ":current" } ```
* Add serde derives for MistrustBuilder.Nick Mathewson2022-05-241-0/+2
| | | | | | The Group and User (de)serialization is pretty ugly, and I can't vouch for the correcness of MistrustBuilder. I will seek feedback before I proceed.
* fs-mistrust: Add Group and User types.Nick Mathewson2022-05-241-0/+1
| | | | | This will help make the actual configuration more serializable, I hope.
* fs-mistrust: make Mistrust have a corresponding Builder type.Nick Mathewson2022-05-241-0/+1
| | | | | This is an approximately minimal revision to get Builder in place; subsequent commits will clean up the API.
* fs-mistrust: Add code to make a self-named group "trusted".Nick Mathewson2022-05-031-0/+2
| | | | | | | | | | | | | | This required a bit of poking through the `users` crate, to mess with the user and group dbs. The original goal was to "trust the group with the same name as us", but it turned into a bit of a production, since: * We want to take our own name from $USER, assuming that matches our uid. (Otherwise we want to ask getpwuid_r().) * We only want to trust the group if we are actually a member of that group. * We want to cache this information. * We want to test this code.

* Add functionality to inspect directory content permissionsNick Mathewson2022-05-031-0/+4
| | | | Also, explain _why_ this is pretty important.
* Second cut at a fs-mistrust crate.Nick Mathewson2022-05-031-0/+20
This crate is meant to solve #315 by giving a way to make sure that a file or directory is only accessible by trusted users. I've tried to explain carefully (in comments and documentation) what this crate is doing and why, under the assumption that it will someday be read by another person like me who does _not_ live and breathe unix file permissions. The crate is still missing some key features, noted in the TODO section. It differs from the first version of the crate by taking a more principled approach to directory checking: it emulates the path lookup process (reading symlinks and all) one path change at a time, thus ensuring that we check every directory which could enable an untrusted user to get to our target file, _or_ which could enable them to get to any symlink that would get them to the target file. The API is also slightly different: It separates the `Mistrust` object (where you configure what you do or do not trust) from the `Verifier` (where you set up a check that you want to perform on a single object). Verifiers are set up to be a bit ephemeral, so that it is hard to accidentally declare that _every_ object is meant to be readable when you only mean that _some_ objects may be readable.
