## Context
the three commits in this series are the first step towards the goal of removing the special casing around `JWT_SECRET`, which is used for various modules via `GetGeneralTokenSigningSecret()`. Ultimately, I want to work towards enabling seamless migration away from general use of the common secret. To enable this, we need proper secret/key rotation support, that is, we need to allow for configuration of additional secrets/keys which are accepted for token validation, but not used to issue tokens.
I have this _Verifier_ support basically implemented, but this PR is not it.
This PR contains cleanup refactoring which I worked on before writing the _Verifier_ support, because I noticed that the existing secret/key handling across modules was inconsistent and required duplicated code.
I am submitting this part now to allow for incremental review of not too large a diff, and because these commits remained unchanged during two weeks since I moved on the the next task.
## The problem being addressed
Configuration of JWT signing secrets/keys was inconsistent:
Under `[oauth2]` the full configuration set was supported:
- `JWT_SIGNING_ALGORITHM` configured the algorithm
- `JWT_SECRET` configured a literal secret for symmetric algorithms
- `JWT_SECRET_URI` configured a `file:` uri of a secret for symmetric algorithms
- `JWT_SIGNING_PRIVATE_KEY_FILE` configured a file for asymmetric algorithms
For `[server]`, the LFS module only supported `LFS_JWT_SECRET`, and the signing method was hardcoded to `HS256`
For `[actions]`, only asymmetric signing methods were supported via `ID_TOKEN_SIGNING_ALGORITHM` and `ID_TOKEN_SIGNING_PRIVATE_KEY_FILE`.
## ini unification
The proposed code centralizes ini parsing to always support the following ini keys:
- `[pfx]SIGNING_ALGORITHM` determines the algorithm
- `[pfx]SECRET` is a literal secret for symmetric algorithms
- `[pfx]SECRET_URI` is the uri of a secret for symmetric algorithms
- `[pfx]SIGNING_PRIVATE_KEY_FILE` is a file with a private key for asymmetric algorithms
`[pfx]` is specific to the module and chosen to support the existing ini keys
Centralizing this code and unifying the ini keys will come handy for at least the following reasons:
- consistent behavior across modules is easier to understand
- less duplicated code
- easier to expand later, which is my main motivation
## implementation notes
as might be apparent by the _take3_ branch name, this is the third iteration of this patch series. The main reason why I abandoned the other two is that I first tried to move all the key initialization into the code called from settings.go when the ini file is parsed. But that lead to a lot of friction with test cases, because private key files which are configured, but do not exist will get created and hence require a writable `AppDataPath` and additional clean up.
To avoid a lot of noise and complications in test cases, I kept the existing two stage process, where
- the settings component creates missing symmetric signing keys and writes them to the .ini
- the settings component creates a simple configuration struct
- which is then used from the module init to create the actual key, which also includes creating a private key file if asymmetric crypto is configured and the key file does not exist.
I would have wished this patch was a net negative in terms of LOCs, but I hope it contributes to clarity and many added lines are in test cases.
## Commits
Because sometimes PRs are merged as squashes with the PR text remaining, I am repeating here the individual messages of the individual commits for future reference:
### Refactor signing key initalization and oauth2 use of it
This commit is the first in a series towards the goal of addressing the
FIXME comment in modules/setting/oauth2.go to remove
GeneralTokenSigningSecret
To do it properly, the task also requires addition of signing secret/key
rotation: We ultimately want to be able to change a signing key, but
continue to accept the previous one. This is particularly relevant to
offer a path from GeneralTokenSigningSecret aka JWT_SECRET to new,
specific component key configuration, where it should be possible to add
the former JWT_SECRET as a key accepted for verification to enable a
seamless transition.
This perspective, in turn, calls for refactoring of the existing secret
initialization code to centralize the common functions of parsing
signing key related configuration directives: The oauth2 module
currently is the only component accepting symmetric and asymmetric keys,
with the limitation of the symmetric key being also the
GeneralTokenSigningSecret. Other components either enforce HS256 or
public key algorithms.
We should really give the choice of algorithm selection and avoid code
duplication in other places, so this commit
- generalizes setting parsing into a configuration struct: A prefix can
be provided, with which the common configuration directives are
processed:
- [pfx]SIGNING_ALGORITHM determines the algorithm
- [pfx]SECRET is a literal secret for symmetric algorithms
- [pfx]SECRET_URI is the uri of a secret for symmetric algorithms
- [pfx]SIGNING_PRIVATE_KEY_FILE is a file with a private key for asymmetric algorithms
- which is then accepted by jwtx.InitSigningKey() to create an actual
signing key
The reasons for the two stage process are explained in a long-ish
comment in modules/setting/security.go. In short, other options would
either violate sensible module boundaries or cause too much friction.
These other options have actually been tried, this is take 3 of the
proposed changes.
### Refactor services/lfs: Change token code to use SigningKey
This now also enables use of token algorithms other than HS256.
In this case, signing key initialization also happens during settings
initialization, because LFS is also used in CLI commands.
### Refactor api/actions to use new signingkey API
This now also enables use of symmetric token algorithms.

- Unify the usage of [`crypto/rand.Read`](https://pkg.go.dev/crypto/rand#Read) to `util.CryptoRandomBytes`.
- Refactor `util.CryptoRandomBytes` to never return an error. It is documented by Go, https://go.dev/issue/66821, to always succeed. So if we still receive a error or if the returned bytes read is not equal to the expected bytes to be read we panic (just to be on the safe side).
- This simplifies a lot of code to no longer care about error handling.

This contains two backwards-compatible changes:
* in the lfs http_client, the number of lfs oids requested per batch is
loaded from lfs_client#BATCH_SIZE and defaulted to the previous value of
20
* in the lfs server/service, the max number of lfs oids allowed in a
batch api request is loaded from server#LFS_MAX_BATCH_SIZE and defaults
to 'nil' which equates to the previous behavior of 'infinite'
This fixes#32306

That's a longstanding INI package problem: the "MustXxx" calls change
the option values, and the following "Save" will save a lot of garbage
options into the user's config file.
Ideally we should refactor the INI package to a clear solution, but it's
a huge work.
A clear workaround is what this PR does: when "Save", load a clear INI
instance and save it.
Partially fix#25377, the "install" page needs more fine tunes.
Follow up #22405Fix#20703
This PR rewrites storage configuration read sequences with some breaks
and tests. It becomes more strict than before and also fixed some
inherit problems.
- Move storage's MinioConfig struct into setting, so after the
configuration loading, the values will be stored into the struct but not
still on some section.
- All storages configurations should be stored on one section,
configuration items cannot be overrided by multiple sections. The
prioioty of configuration is `[attachment]` > `[storage.attachments]` |
`[storage.customized]` > `[storage]` > `default`
- For extra override configuration items, currently are `SERVE_DIRECT`,
`MINIO_BASE_PATH`, `MINIO_BUCKET`, which could be configured in another
section. The prioioty of the override configuration is `[attachment]` >
`[storage.attachments]` > `default`.
- Add more tests for storages configurations.
- Update the storage documentations.

According to the discussion with DanielGibson, the default "20m" seems
too short. It would make LFS fail if the file is large / network is
slow.
I think relaxing this timeout doesn't have side affect. So change the
default value to 24h, IMO that should be long enough.
## ⚠️ BREAKING
If admins want the previous timeout, they should set the setting
`[server].LFS_HTTP_AUTH_EXPIRY`.
Some bugs caused by less unit tests in fundamental packages. This PR
refactor `setting` package so that create a unit test will be easier
than before.
- All `LoadFromXXX` files has been splited as two functions, one is
`InitProviderFromXXX` and `LoadCommonSettings`. The first functions will
only include the code to create or new a ini file. The second function
will load common settings.
- It also renames all functions in setting from `newXXXService` to
`loadXXXSetting` or `loadXXXFrom` to make the function name less
confusing.
- Move `XORMLog` to `SQLLog` because it's a better name for that.
Maybe we should finally move these `loadXXXSetting` into the `XXXInit`
function? Any idea?
