| * [PATCH] PCI Error Recovery: documentationlinas@austin.ibm.com2006-01-091-0/+246
| | | | | | | | | | | | | | | | | | | | | | Various PCI bus errors can be signaled by newer PCI controllers. Recovering from those errors requires an infrastructure to notify affected device drivers of the error, and a way of walking through a reset sequence. This patch adds documentation describing the current error recovery proposal. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
| * [PATCH] PCI: document sysfs rom file interfaceJesse Barnes2006-01-091-6/+15
| | | | | | | | | | | | | | | | | | | | | | | | idr gently pointed out today that not only is the sysfs rom file interface somewhat unintuitive (despite my efforts and initial implementation), but it's also undocumented! This patch to Documentation/filesystems/sysfs-pci.txt corrects the latter problem; the former is a userland ABI now though, so we're stuck with it for awhile at least.

This release is almost identical to the version for the 2.6.14 kernel posted earlier, which is available as part of the Cell BE Linux distribution from http://www.bsc.es/projects/deepcomputing/linuxoncell/. The first patch provides all the interfaces for running spu application, but does not have any support for debugging SPU tasks or for scheduling. Both these functionalities are added in the subsequent patches. See Documentation/filesystems/spufs.txt on how to use spufs.

* | [PATCH] keys: Permit running process to instantiate keysDavid Howells2006-01-082-10/+36

The patch makes the following changes: (1) A new, optional key type method has been added. This permits a key type to intercept requests at the point /sbin/request-key is about to be spawned and do something else with them - passing them over the rpc_pipefs files or netlink sockets for instance. The uninstantiated key, the authorisation key and the intended operation name are passed to the method. (2) The callout_info is no longer passed as an argument to /sbin/request-key to prevent unauthorised viewing of this data using ps or by looking in /proc/pid/cmdline. This means that the old /sbin/request-key program will not work with the patched kernel as it will expect to see an extra argument that is no longer there. A revised keyutils package will be made available tomorrow. (3) The callout_info is now attached to the authorisation key. Reading this key will retrieve the information. (4) A new field has been added to the task_struct. This holds the authorisation key currently active for a thread. Searches now look here for the caller's set of keys rather than looking for an auth key in the lowest level of the session keyring. This permits a thread to be servicing multiple requests at once and to switch between them. Note that this is per-thread, not per-process, and so is usable in multithreaded programs. The setting of this field is inherited across fork and exec. (5) A new keyctl function (KEYCTL_ASSUME_AUTHORITY) has been added that permits a thread to assume the authority to deal with an uninstantiated key. Assumption is only permitted if the authorisation key associated with the uninstantiated key is somewhere in the thread's keyrings. This function can also clear the assumption. (6) A new magic key specifier has been added to refer to the currently assumed authorisation key (KEY_SPEC_REQKEY_AUTH_KEY). (7) Instantiation will only proceed if the appropriate authorisation key is assumed first. The assumed authorisation key is discarded if instantiation is successful. (8) key_validate() is moved from the file of request_key functions to the file of permissions functions. (9) The documentation is updated. From: <Valdis.Kletnieks@vt.edu> Build fix.
