* [PATCH] Keys: Fix race between two instantiators of a keyDavid Howells2006-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a revocation notification method to the key type and calls it whilst the key's semaphore is still write-locked after setting the revocation flag. The patch then uses this to maintain a reference on the task_struct of the process that calls request_key() for as long as the authorisation key remains unrevoked. This fixes a potential race between two processes both of which have assumed the authority to instantiate a key (one may have forked the other for example). The problem is that there's no locking around the check for revocation of the auth key and the use of the task_struct it points to, nor does the auth key keep a reference on the task_struct. Access to the "context" pointer in the auth key must thenceforth be done with the auth key semaphore held. The revocation method is called with the target key semaphore held write-locked and the search of the context process's keyrings is done with the auth key semaphore read-locked. The check for the revocation state of the auth key just prior to searching it is done after the auth key is read-locked for the search. This ensures that the auth key can't be revoked between the check and the search. The revocation notification method is added so that the context task_struct can be released as soon as instantiation happens rather than waiting for the auth key to be destroyed, thus avoiding the unnecessary pinning of the requesting process.

* [PATCH] selinux: add hooks for key subsystemMichael LeMay2006-06-22
| | | | | | | | | | | | | | | | | | | Introduce SELinux hooks to support the access key retention subsystem within the kernel. Incorporate new flask headers from a modified version of the SELinux reference policy, with support for the new security class representing retained keys. Extend the "key_alloc" security hook with a task parameter representing the intended ownership context for the key being allocated. Attach security information to root's default keyrings within the SELinux initialization routine. Has passed David's testsuite.

* [ALSA] snd-powermac: no longer handle anything with a layout-id propertyJohannes Berg2006-06-22
| | | | | | | | | | | This patch removes from snd-powermac the code that check for the layout-id and instead adds code that makes it refuse loading when a layout-id property is present, nothing that snd-aoa should be used. It also removes the 'toonie' codec from snd-powermac which was only ever used on the mac mini which has a layout-id property.

* [ALSA] snd-aoa: add snd-aoaJohannes Berg2006-06-22
| | | | | | | | | | | | | | | | | This large patch adds all of snd-aoa. Consisting of many modules, it currently replaces snd-powermac for all layout-id based machines and handles many more (for example new powerbooks and powermacs with digital output that previously couldn't be used at all). It also has support for all layout-IDs that Apple has (judging from their Info.plist file) but not all are tested. The driver currently has 2 known regressions over snd-powermac: * it doesn't handle powermac 7,2 and 7,3 * it doesn't have a DRC control on snapper-based machines I will fix those during the 2.6.18 development cycle.
