This adds the operation mode "strict". It does not yet have
any specific features and alias the "normal" mode.
This change is mostly to make the setting of "strict" valid
so it can be used already.
<event> has been added and can be used within <kartoffelsalat>
both in <icecast> and <mount>.
<event> takes backend depending <option> child tags.
Currently supported backends:
- log: send message to error log.
- exec: executes a program or script.
- url: delivers the event via HTTP.
within <mount> <on-connect> and <on-disconnect> has been replaced by
<event>. Config parser can on-the-fly convert old tags.
Also <authentication type="url"> within <mount> has been fixed
for those cases with <option name="mount_add" .../> and
<option name="mount_remove" .../> which are now on-the-fly converted
by the parser to corresponding <event> tags.
Please also see TAGs added as per #2098. Some include hints for
documentation updates needed after this change. Those updates
should take place before 2.4.2.
Renamed event_config_read() into config_reread_config() and moved
it into cfgfile.c. This allowed to delete event.[ch].
event.[ch] will later be used to implement <event>.
This patch *replaces* the authentication system completly.
What is new:
- <authentication> in mount section is now a container object.
- <authentication> in root and mount section may hold any number of <role>-Tags.
- <role> tags:
Those tags define a 'role' and it's ACL rules.
A role is a instance of an authentication module (see below).
<role> takes the following options. All but type are optional.
- authentication related:
- type: Type of the authentication module (values: anonymous, static, legacy-password, url or htpasswd;
symbolic constants in auth.h)
- name: Name for the role. For later matching. (values: any string; default: (none))
- method: This rule is only active on the given list of HTTP methods.
(list of enum values: methods as recognized by httpp/ (e.g: get,post); default: *)
- ACL related:
- allow-method: Allowed HTTP methods.
(list of enum values: methods as recognized by httpp/ (e.g: get,post); default: get)
- deny-method: Rejected HTTP methods.
(list of enum values: methods as recognized by httpp/ (e.g: get,post); default: *)
- allow-admin: Allowed admin commands. (list of enum values: admin command; default: buildm3u)
- deny-admin: Rejected admin commands. (list of enum values: admin command; default: *)
- allow-web: Allowed web pages. (values: empty or *; default: *)
- deny-web: Rejected web pages. (values: empty or *; default: (empty))
- connections-per-user: maximum number of simultaneous connections per role and username.
This is only active on active sources. (values: unlimited or number of connections; default: unlimited)
- connection-duration: maximum time of a connection. This is only active on active sources.
(values: unlimited or number of secounds; default: unlimited)
<role> takes <option> child tags. <option> tags contain a name and a value option.
Meaning of <option> tags is up to the authentication module.
- <role>s are considered to build a stack. If a role returns with AUTH_NOMATCH the next one will be tried.
- <role>s are tested in this order: mount specific, default mount specific, global, internal fallback.
Internal fallback is set to allow web/ access via GET, POST and HEAD (only GET supported by this time)
and rejects all other requests.
- New authentication module: anonymous
This module matches all requests. No options taken.
- New authentication module: static
This module matches with a static username and password.
It takes two <option>s. One with name="username" and one with name="password" to set username and password.
This replaces old style <*-username> and <*-password> tags.
- New authentication module: legacy-password
This module matches with a statich password.
It takes one <option> with name="password" to set password.
This replaces old ICE and ICY (shoutcast compat mode) authentication.
- Parsing <authentication> in <mount> with a type set in a special way to allow 100% backward compatibility.
- Parsing of <source-password>, <admin-password>, <admin-user>, <relay-password> and <relay-user> in global
<authentication> for 100% backward compatibility.
- <alias> is now proccessed very early. This enables them to be used for all kinds of requests.
To Do List & What does not yet work:
- type="url" auth: mount_add and mount_remove.
This should be replaced by an unique feature I would call '<event>'.
- Admin commands manageauth and manageauth.xsl are disabled as they need more review:
This code needs to be ported to support multiple <role>s per <mount>.
- url authentication module can not yet return AUTH_NOMATCH.
This needs to be reviewed and discussed on how to handle this case best way.
- Default config files needs to be updated to reflect the changes.
As this is quite some political act it should be done in dicussion with the whole team
and permission of the release manager.
- Docs need to be updated to reflect the changes.
How does it work:
Code has been changed so that authentification is done early for all clients.
This allows accessing the ACL data (client->acl) from nearly everywhere in the code.
After accept() and initial client setup the request is parsed. In the next step
all <alias>es are resolved. After this the client is passed for authentication.
After authentication it is passed to the corresponding subsystem depending on kind of request.
All authentication instances have a thread running for doing the authentication.
This thread works on a queue of clients.
Hints for testers:
- Test with default config.
- Test with diffrent authentication modules in <mount>.
- Test shoutcast compatibility mode.
- Test with new style <authentication> and any amount of <role> (zero to quite some).
- Test <alias> lookup on all kinds of objects.
- Test source level credential login into the admin interface.
- Test shoucast style meta data updates.
- Test playlist generation.
Thank you for reading this long commit message. Have fun reading the full patch!

The default mount is a block in the config file that contains settings for
all mount points that do not have a block in configfile themself.
This is implemented by a <mount type="default">-block.
In this case the <mount>-block MUST NOT contain a <mount-name>-subblock.

specifying the TCP send buffer size, it seems that on at least some win32 systems,
the window size stays at 8k (even with registry settings) which could limit available
streaming bandwidth.

provide a mountpoint so you specify a shoutcast-mount in the listen-socket
section. Specifying this will automatically define the port+1 with the same
settings however the original shoutcast-compat approach is maintained.

ISO-8859-1 is assumed as there is no real clarity wrt the spec. In most cases people
send ASCII so it's not an issue, but for some, the extended characters they send
can cause problems with XML processing. As stats and YP require UTF8 we need to
translate them and block invalid cases.
For the moment, for non-Ogg streams only, we assume that the metadata needs converting
from ISO-8859-1. Ogg streams are UTF8 so no conversion needed. You can override the
default with a charset mount option.

which can be used to handle authentication mechanisms without taking locks
for long periods. Non-authenticated mountpoints bypass the auth thread.
The lookup/checking of the source_t is done after the authentication succeeds
so the fallback mechanism does not affect which authenticator is used. This
can be extended to allow us to authenticate in webroot as well. XML re-read
changes will take effect immediately for new listeners but existing listeners
will use the original auth_t (refcounted) when they exit.
htpasswd access has been seperated out from auth.c, and implements an AVL
tree for a faster username lookup. The htpasswd file timestamp is checked
just in case there are changes made externally
