| |
These patches add local caching for network filesystems such as NFS.
The patches can roughly be broken down into a number of sets:
(*) 01-keys-inc-payload.diff (*) 02-keys-search-keyring.diff (*) 03-keys-callout-blob.diff
Three patches to the keyring code made to help the CIFS people. Included because of patches 05-08.
(*) 04-keys-get-label.diff
A patch to allow the security label of a key to be retrieved. Included because of patches 05-08.
(*) 05-security-current-fsugid.diff (*) 06-security-separate-task-bits.diff (*) 07-security-subjective.diff (*) 08-security-kernel_service-class.diff (*) 09-security-kernel-service.diff (*) 10-security-nfsd.diff
Patches to permit the subjective security of a task to be overridden. All the security details in task_struct are decanted into a new struct that task_struct then has two pointers two: one that defines the objective security of that task (how other tasks may affect it) and one that defines the subjective security (how it may affect other objects).
Note that I have dropped the idea of struct cred for the moment. With the amount of stuff that was excluded from it, it wasn't actually any use to me. However, it can be added later.
Required for cachefiles.
(*) 11-release-page.diff (*) 12-fscache-page-flags.diff (*) 13-add_wait_queue_tail.diff (*) 14-fscache.diff
Patches to provide a local caching facility for network filesystems.
(*) 15-cachefiles-ia64.diff (*) 16-cachefiles-ext3-f_mapping.diff (*) 17-cachefiles-write.diff (*) 18-cachefiles-monitor.diff (*) 19-cachefiles-export.diff (*) 20-cachefiles.diff
Patches to provide a local cache in a directory of an already mounted filesystem.
(*) 21-nfs-comment.diff (*) 22-nfs-fscache-option.diff (*) 23-nfs-fscache-kconfig.diff (*) 24-nfs-fscache-top-index.diff (*) 25-nfs-fscache-server-obj.diff (*) 26-nfs-fscache-super-obj.diff (*) 27-nfs-fscache-inode-obj.diff (*) 28-nfs-fscache-use-inode.diff (*) 29-nfs-fscache-invalidate-pages.diff (*) 30-nfs-fscache-iostats.diff (*) 31-nfs-fscache-page-management.diff (*) 32-nfs-fscache-read-context.diff (*) 33-nfs-fscache-read-fallback.diff (*) 34-nfs-fscache-read-from-cache.diff (*) 35-nfs-fscache-store-to-cache.diff (*) 36-nfs-fscache-mount.diff (*) 37-nfs-fscache-display.diff
Patches to provide NFS with local caching.
A couple of questions on the NFS iostat changes: (1) Should I update the iostat version number; (2) is it permitted to have conditional iostats?
I've brought the patchset up to date with respect to the 2.6.25-rc1 merge window, in particular altering Smack to handle the split in objective and subjective security in the task_struct.
-- A tarball of the patches is available at:
http://people.redhat.com/~dhowells/fscache/patches/nfs+fscache-30.tar.bz2
To use this version of CacheFiles, the cachefilesd-0.9 is also required. It is available as an SRPM:
http://people.redhat.com/~dhowells/fscache/cachefilesd-0.9-1.fc7.src.rpm
Or as individual bits:
http://people.redhat.com/~dhowells/fscache/cachefilesd-0.9.tar.bz2 http://people.redhat.com/~dhowells/fscache/cachefilesd.fc http://people.redhat.com/~dhowells/fscache/cachefilesd.if http://people.redhat.com/~dhowells/fscache/cachefilesd.te http://people.redhat.com/~dhowells/fscache/cachefilesd.spec
The .fc, .if and .te files are for manipulating SELinux.
