- This is a 'front-port' of the already existing patch on v1.21 and
v1.20, but applied on top of what Gitea has done to rework the LTA
mechanism. Forgejo will stick with the reworked mechanism by the Forgejo
Security team for the time being. The removal of legacy code (AES-GCM) has been
left out.
- The current architecture is inherently insecure, because you can
construct the 'secret' cookie value with values that are available in
the database. Thus provides zero protection when a database is
dumped/leaked.
- This patch implements a new architecture that's inspired from: [Paragonie Initiative](https://paragonie.com/blog/2015/04/secure-authentication-php-with-long-term-persistence#secure-remember-me-cookies).
- Integration testing is added to ensure the new mechanism works.
- Removes a setting, because it's not used anymore.

Fixes #27819
We have support for two factor logins with the normal web login and with
basic auth. For basic auth the two factor check was implemented at three
different places and you need to know that this check is necessary. This
PR moves the check into the basic auth itself.
The steps to reproduce it.
First, create a new oauth2 source.
Then, a user login with this oauth2 source.
Disable the oauth2 source.
Visit users -> settings -> security, 500 will be displayed.
This is because this page only load active Oauth2 sources but not all
Oauth2 sources.
Closes #27455
> The mechanism responsible for long-term authentication (the 'remember
me' cookie) uses a weak construction technique. It will hash the user's
hashed password and the rands value; it will then call the secure cookie
code, which will encrypt the user's name with the computed hash. If one
were able to dump the database, they could extract those two values to
rebuild that cookie and impersonate a user. That vulnerability exists
from the date the dump was obtained until a user changed their password.
>
> To fix this security issue, the cookie could be created and verified
using a different technique such as the one explained at
https://paragonie.com/blog/2015/04/secure-authentication-php-with-long-term-persistence#secure-remember-me-cookies.
The PR removes the now obsolete setting `COOKIE_USERNAME`.
When the user does not set a username lookup condition, LDAP will get an
empty string `""` for the user, hence the following code
```
if isExist, err := user_model.IsUserExist(db.DefaultContext, 0, sr.Username)
```
The user presence determination will always be nonexistent, so updates
to user information will never be performed.
Fix #27049
Part of #27065
This reduces the usage of `db.DefaultContext`. I think I've got enough
files for the first PR. When this is merged, I will continue working on
this.
Considering how many files this PR affect, I hope it won't take to long
to merge, so I don't end up in the merge conflict hell.

Bumping `github.com/golang-jwt/jwt` from v4 to v5.
`github.com/golang-jwt/jwt` v5 is bringing some breaking changes:
- standard `Valid()` method on claims is removed. It's replaced by
`ClaimsValidator` interface implementing `Validator()` method instead,
which is called after standard validation. Gitea doesn't seem to be
using this logic.
- `jwt.Token` has a field `Valid`, so it's checked in `ParseToken`
function in `services/auth/source/oauth2/token.go`

we refactored `userIDFromToken` for the token parsing part into a new
function `parseToken`. `parseToken` returns the string `token` from
request, and a boolean `ok` representing whether the token exists or
not. So we can distinguish between token non-existence and token
inconsistency in the `verfity` function, thus solving the problem of no
proper error message when the token is inconsistent.

Fix #21072
Username Attribute is not a required item when creating an
authentication source. If Username Attribute is empty, the username
value of LDAP user cannot be read, so all users from LDAP will be marked
as inactive by mistake when synchronizing external users.
This PR improves the sync logic, if username is empty, the email address
will be used to find user.
1. The "web" package shouldn't depends on "modules/context" package,
instead, let each "web context" register themselves to the "web"
package.
2. The old Init/Free doesn't make sense, so simplify it
* The ctx in "Init(ctx)" is never used, and shouldn't be used that way
* The "Free" is never called and shouldn't be called because the SSPI
instance is shared

The plan is that all built-in auth providers use inline SVG for more
flexibility in styling and to get the GitHub icon to follow
`currentcolor`. This only removes the `public/img/auth` directory and
adds the missing svgs to our svg build.
It should map the built-in providers to these SVGs and render them. If
the user has set a Icon URL, it should render that as an `img` tag
instead.

Fix #24856
Rename "context.contextKey" to "context.WebContextKey", this context is
for web context only. But the Context itself is not renamed, otherwise
it would cause a lot of changes (if we really want to rename it, there
could be a separate PR).
The old test code doesn't really test, the "install page" gets broken
not only one time, so use new test code to make sure the "install page"
could work.
Replace #16455
Close #21803
Mixing different Gitea contexts together causes some problems:
1. Unable to respond proper content when error occurs, eg: Web should
respond HTML while API should respond JSON
2. Unclear dependency, eg: it's unclear when Context is used in
APIContext, which fields should be initialized, which methods are
necessary.
To make things clear, this PR introduces a Base context, it only
provides basic Req/Resp/Data features.
This PR mainly moves code. There are still many legacy problems and
TODOs in code, leave unrelated changes to future PRs.

"registration success email" is only used for notifying a user that "you
have a new account now" when the account is created by admin manually.
When a user uses external auth source, they already knows that they has
the account, so do not send such email.

Partially for #24457
Major changes:
1. The old `signedUserNameStringPointerKey` is quite hacky, use
`ctx.Data[SignedUser]` instead
2. Move duplicate code from `Contexter` to `CommonTemplateContextData`
3. Remove incorrect copying&pasting code `ctx.Data["Err_Password"] =
true` in API handlers
4. Use one unique `RenderPanicErrorPage` for panic error page rendering
5. Move `stripSlashesMiddleware` to be the first middleware
6. Install global panic recovery handler, it works for both `install`
and `web`
7. Make `500.tmpl` only depend minimal template functions/variables,
avoid triggering new panics

> The scoped token PR just checked all API routes but in fact, some web
routes like `LFS`, git `HTTP`, container, and attachments supports basic

This allows for usernames, and emails connected to them to be reserved
and not reused.
Use case, I manage an instance with open registration, and sometimes
when users are deleted for spam (or other purposes), their usernames are
freed up and they sign up again with the same information.
This could also be used to reserve usernames, and block them from being
registered (in case an instance would like to block certain things
without hardcoding the list in code and compiling from scratch).
This is an MVP, that will allow for future work where you can set
something as reserved via the interface.

Close #24062
At the beginning, I just wanted to fix the warning mentioned by #24062
But, the cookie code really doesn't look good to me, so clean up them.
Complete the TODO on `SetCookie`:
> TODO: Copied from gitea.com/macaron/macaron and should be improved
after macaron removed.
In the `for` loop, the value of `membershipsToAdd[org]` and
`membershipsToRemove[org]` is a slice that should be appended instead of
overwritten.
Due to the current overwrite, the LDAP group sync only matches the last
group at the moment.
## Example reproduction
- an LDAP user is both a member of
`cn=admin_staff,ou=people,dc=planetexpress,dc=com` and
`cn=ship_crew,ou=people,dc=planetexpress,dc=com`.
- configuration of `Map LDAP groups to Organization teams ` in
`Authentication Sources`:
```json
{
"cn=admin_staff,ou=people,dc=planetexpress,dc=com":{
"test_organization":[
"admin_staff",
"test_add"
]
},
"cn=ship_crew,ou=people,dc=planetexpress,dc=com":{
"test_organization":[
"ship_crew"
]
}
```
- start `Synchronize external user data` task in the `Dashboard`.
- the user was only added for the team `test_organization.ship_crew`
None of the features of `unrolled/render` package is used.
The Golang builtin "html/template" just works well. Then we can improve
our HTML render to resolve the "$.root.locale.Tr" problem as much as
possible.
Next step: we can have a template render pool (by Clone), then we can
inject global functions with dynamic context to every `Execute` calls.
Then we can use `{{Locale.Tr ....}}` directly in all templates , no need
to pass the `$.root.locale` again and again.
When running listLdapGroupMemberships check if the groupFilter is empty
before using it to list memberships.
