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!

issue requests (using ithe stream_auth option) to allow external engines to
determine whether a client can stream or not. Admin requests using source auth
are able to use this mechanism however source clients using the icy protocol
cannot yet.

whilst no source was reserved then those stats were left behind.

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

stream settings also allow for overriding the incoming settings.

it is at the right point. kick off the YP 'add' 5 seconds after source startup
so that any stats are processed.

You can now use the Shoutcast DSP as a source client. The connection
protocol is a bit odd, and we had to handle it separately, and thus
we've added a new config option (<shoutcast-compat>) that is set at
the listener port level.
* support for NSV (and the nsvscsrc source client).
After adding support for the connection protocol of the shoutcast DSP,
adding NSV was just a simple of a few special handling cases.
* removed all traces of the earlier attempt at the shoutcast DSP connection
protocol
* Due to the growing complexity of the config files, I've also created a
few alternate config files, namely one for a "shoutcast compat" setup
as well as a "minimal" one for quick basic configurations.

- most of the yp processing now moved into the yp add/touch thread
- use ice/icy-public rather than ice/icy-private to coorespond to libshout and general convention
- memory leak fixed with audio-info

caused significant lock contention with many sources. Further, a single refbuf
is never used by more than one source (and hence one thread), so the locking
was unneeded.
Fix a nasty bug in source.c:_compare_clients() - was casting a void pointer
to the wrong type, and hence all the tree-maintaince comparisons were totally
wrong (but due to the exact nature of the bug this wasn't causing any active
problems until...)
Add another admin command to kill a client - remove it using an id. Note that
many clients will do auto-reconnect, so this may not be sufficient on its own,
we might need a ban (possibly temporary) function.

another (without shutting the old source down)

communicate things like samplerate/quality/number of channels to
icecast2. This info will be then forwarded to the yp servers for
better stream info.
also factored out some logic in source_main into common functions

the config file, but they aren't yet used).
svn path=/trunk/icecast/; revision=4338
make streams public by default, send ice-private: 1 to make them private.
However, default config file has yp servers commented out.
A little fix for compilation on some solaris systems
Redo some config file stuff: now all the passwords are inside an element
<authentication>, (though for now they're also accepted in the old location),
and added admin username and password. Move some of the admin activities over
to using the admin passwords (admin action that affect a mountpoint use the
source password)
Fill in some (but not yet all, maybe i'll do that later) of the infrastructure
for per-mountpoint passwords.
Fix lots of headers/code so that it works properly/portably on non-win32
systems.
