2008-07-14[S390] cio: suppress chpid event in case of configure errorPeter Oberparleiter

2008-07-14[S390] css: Use css_device_id for bus matching.Cornelia Huck
css_device_id exists, so use it for determining the right driver (and add a match_flags which is always 1 for valid types). Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
2008-07-14[S390] cio: Repair chpid event handling.Cornelia Huck
Passing the affected chpid in chp_event() worked only by chance since chpid is the first element in res_acc_data. Make it work properly by generalizing res_acc_data as chp_link and always passing around a properly filled out chp_link structure in chp_event().

2008-07-14[S390] cio: Allow adapter interrupt handlers per isc.Cornelia Huck
Enhance the adapter interruption API so that device drivers can register a handler for a specific interruption subclass.

2008-07-14[S390] initrd vs bss section clearing.Heiko Carstens
In case the initrd is located within the bss section it will be overwritten when the section is cleared. To prevent this just move the initrd right behind the bss section if it starts within the section. The current code already moves the initrd if the bootmem allocator bitmap would overwrite it. With this patch we should be safe against initrd corruptions.

If qdio shutdown runs in parallel with a channel error, the qdio_timeout_handler might not be triggered. In this case neither state INACTIVE nor state ERR is reached and the following wait_event hangs forever.

2008-07-14SELinux: allow fstype unknown to policy to use xattrs if presentEric Paris
Currently if a FS is mounted for which SELinux policy does not define an fs_use_* that FS will either be genfs labeled or not labeled at all. This decision is based on the existence of a genfscon rule in policy and is irrespective of the capabilities of the filesystem itself. This patch allows the kernel to check if the filesystem supports security xattrs and if so will use those if there is no fs_use_* rule in policy. An fstype with a no fs_use_* rule but with a genfs rule will use xattrs if available and will follow the genfs rule. This can be particularly interesting for things like ecryptfs which actually overlays a real underlying FS. If we define excryptfs in policy to use xattrs we will likely get this wrong at times, so with this path we just don't need to define it! Overlay ecryptfs on top of NFS with no xattr support: SELinux: initialized (dev ecryptfs, type ecryptfs), uses genfs_contexts Overlay ecryptfs on top of ext4 with xattr support: SELinux: initialized (dev ecryptfs, type ecryptfs), uses xattr It is also useful as the kernel adds new FS we don't need to add them in policy if they support xattrs and that is how we want to handle them.
