45fa9e5ae9 fix: Allow Organisations to remove the Email Address (#5517)
It is possible to set a Email for a Organization. This Email is optional and only used to be displayed on the profile page. However, once you set an EMail, you can no longer remove it. This PR fixes that.

While working on the tests, I found out, that the API returns a 500 when trying to set an invalid EMail. I fixed that too. It returns a 422 now.

Fixes #4567

fix: extend forgejo_auth_token table
- Add a `purpose` column, this allows the `forgejo_auth_token` table to
be used by other parts of Forgejo, while still enjoying the
no-compromise architecture.
- Remove the 'roll your own crypto' time limited code functions and
migrate them to the `forgejo_auth_token` table. This migration ensures
generated codes can only be used for their purpose and ensure they are
invalidated after their usage by deleting it from the database, this
also should help making auditing of the security code easier, as we're
no longer trying to stuff a lot of data into a HMAC construction.
-Helper functions are rewritten to ensure a safe-by-design approach to
these tokens.
- Add the `forgejo_auth_token` to dbconsistency doctor and add it to the
`deleteUser` function.
- TODO: Add cron job to delete expired authorization tokens.
- Unit and integration tests added.

[SECURITY] Notify users about account security changes
- Currently if the password, primary mail, TOTP or security keys are
changed, no notification is made of that and makes compromising an
account a bit easier as it's essentially undetectable until the original
person tries to log in. Although other changes should be made as
well (re-authing before allowing a password change), this should go a
long way of improving the account security in Forgejo.
- Adds a mail notification for password and primary mail changes. For
the primary mail change, a mail notification is sent to the old primary
mail.
- Add a mail notification when TOTP or a security keys is removed, if no
other 2FA method is configured the mail will also contain that 2FA is
no longer needed to log into their account.
- `MakeEmailAddressPrimary` is refactored to the user service package,
as it now involves calling the mailer service.
- Unit tests added.
- Integration tests added.

allow synchronizing user status from OAuth2 login providers (#31572)
This leverages the existing `sync_external_users` cron job to
synchronize the `IsActive` flag on users who use an OAuth2 provider set
to synchronize. This synchronization is done by checking for expired
access tokens, and using the stored refresh token to request a new
access token. If the response back from the OAuth2 provider is the
`invalid_grant` error code, the user is marked as inactive. However, the
user is able to reactivate their account by logging in the web browser
through their OAuth2 flow.

Also changed to support this is that a linked `ExternalLoginUser` is
always created upon a login or signup via OAuth2.

Ideally, we would also refresh permissions from the configured OAuth
provider (e.g., admin, restricted and group mappings) to match the
implementation of LDAP. However, the OAuth library used for this `goth`,
doesn't seem to support issuing a session via refresh tokens. The
interface provides a [`RefreshToken`
method](https://github.com/markbates/goth/blob/master/provider.go#L20),
but the returned `oauth.Token` doesn't implement the `goth.Session` we
would need to call `FetchUser`. Due to specific implementations, we
would need to build a compatibility function for every provider, since
they cast to concrete types (e.g.
[Azure](https://github.com/markbates/goth/blob/master/providers/azureadv2/azureadv2.go#L132))

8a1924b51a [PORT] Use FullName in Emails to address the recipient if possible (gitea#31527) (#4516)
Before we had just the plain mail address as recipient. But now we provide additional Information for the Mail clients.

---
Porting information:

- Two behavior changes are noted with this patch, the display name is now always quoted although in some scenarios unnecessary it's a safety precaution of Go. B encoding is used when certain characters are present as they aren't 'legal' to be used as a display name and Q encoding would still show them and B encoding needs to be used, this is now done by Go's `address.String()`.
- Update and add new unit tests.

so how would you like me to invoke `lint-codespell` on CI? (without that would be IMHO very suboptimal and let typos sneak in)

Implement remote user login source and promotion to regular user
A remote user (UserTypeRemoteUser) is a placeholder that can be
promoted to a regular user (UserTypeIndividual). It represents users
that exist somewhere else. Although the UserTypeRemoteUser already
exists in Forgejo, it is neither used or documented.

A new login type / source (Remote) is introduced and set to be the login type
of remote users.

Type        UserTypeRemoteUser
LogingType  Remote

The association between a remote user and its counterpart in another
environment (for instance another forge) is via the OAuth2 login
source:

LoginName   set to the unique identifier relative to the login source
LoginSource set to the identifier of the remote source

For instance when migrating from GitLab.com, a user can be created as
if it was authenticated using GitLab.com as an OAuth2 authentication
source.

When a user authenticates to Forejo from the same authentication
source and the identifier match, the remote user is promoted to a
regular user. For instance if 43 is the ID of the GitLab.com OAuth2
login source, 88 is the ID of the Remote loging source, and 48323
is the identifier of the foo user:

Type        UserTypeRemoteUser
LogingType  Remote
LoginName   48323
LoginSource 88
Email       (empty)
Name        foo

Will be promoted to the following when the user foo authenticates to
the Forgejo instance using GitLab.com as an OAuth2 provider. All users
with a LoginType of Remote and a LoginName of 48323 are examined. If
the LoginSource has a provider name that matches the provider name of
GitLab.com (usually just "gitlab"), it is a match and can be promoted.

The email is obtained via the OAuth2 provider and the user set to:

Type        UserTypeIndividual
LogingType  OAuth2
LoginName   48323
LoginSource 43
Email       foo@example.com
Name        foo

Note: the Remote login source is an indirection to the actual login
source, i.e. the provider string my be set to a login source that does
not exist yet.

[BUG] Don't delete inactive emails explicitly
- `user_model.DeleteInactiveEmailAddresses` related code was added in
Gogs as part to delete inactive users, however since then the related
code to delete users has changed and this code now already delete email
addresses of the user, it's therefore not needed anymore to
`DeleteInactiveEmailAddresses`.
- The call to `DeleteInactiveEmailAddresses` can actually cause issues.
As the associated user might not have been deleted, because it
was not older than the specified `olderThan` argument. Therefore causing
a database inconsistency and lead to internal server errors if the user
tries to activate their account.
- Adds unit test to verify correct behavior (fails without this patch).

Allow users to hide all "Add more units..." hints
Repositories displaying an "Add more..." tab on the header is a neat way
to let people discover they can enable more units. However, displaying
it all the time for repository owners, even when they deliberately do
not want to enable more units gets noisy very fast.

As such, this patch introduces a new setting which lets people disable
this hint under the appearance settings.

Fixes #2378.

Only use supported sort order for "explore/users" page (#29430)
Thanks to inferenceus : some sort orders on the "explore/users" page
could list users by their lastlogintime/updatetime.

It leaks user's activity unintentionally. This PR makes that page only
use "supported" sort orders.

Removing the "sort orders" could also be a good solution, while IMO at
the moment keeping the "create time" and "name" orders is also fine, in
case some users would like to find a target user in the search result,
the "sort order" might help.

[gitea] Drop "@" from email sender to avoid spam filters (#29109)
Commit 360b3fd17c (Include username in email headers (#28981),
2024-02-03) adds usernames to the From field of notification emails in
the form of `Display Name (@username)`, to prevent spoofing. However,
some email filtering software flags "@" in the display name part of the
From field as potential spoofing, as you could set the display name part
to another email address than the one you are sending from (e.g.
`From: "apparent@email-address" <actual@email-address>`). To avoid
being flagged, instead send emails from `Display Name (username)`.

Closes: #29107

[GITEA] Allow changing the email address before activation
During registration, one may be required to give their email address, to
be verified and activated later. However, if one makes a mistake, a
typo, they may end up with an account that cannot be activated due to
having a wrong email address.

They can still log in, but not change the email address, thus, no way to
activate it without help from an administrator.

To remedy this issue, lets allow changing the email address for logged
in, but not activated users.

This fixes gitea#17785.

[GITEA] Allow changing the email address before activation (squash) cache is always active

This needs to be revisited because the MailResendLimit is not enforced
and turns out to not be tested.

See e7cb8da2a8 * Always enable caches (#28527)

(cherry picked from commit 43ded8ee30)

Rate limit pre-activation email change separately

Changing the email address before any email address is activated should
be subject to a different rate limit than the normal activation email
resending. If there's only one rate limit for both, then if a newly
signed up quickly discovers they gave a wrong email address, they'd have
to wait three minutes to change it.

With the two separate limits, they don't - but they'll have to wait
three minutes before they can change the email address again.

The downside of this setup is that a malicious actor can alternate
between resending and changing the email address (to something like
`user+$idx@domain`, delivered to the same inbox) to effectively halving
the rate limit. I do not think there's a better solution, and this feels
like such a small attack surface that I'd deem it acceptable.

The way the code works after this change is that `ActivatePost` will now
check the `MailChangeLimit_user` key rather than `MailResendLimit_user`,
and if we're within the limit, it will set `MailChangedJustNow_user`. The
`Activate` method - which sends the activation email, whether it is a
normal resend, or one following an email change - will check
`MailChangedJustNow_user`, and if it is set, it will check the rate
limit against `MailChangedLimit_user`, otherwise against
`MailResendLimit_user`, and then will delete the
`MailChangedJustNow_user` key from the cache.

Fixes #2040.
