* afs: Get YFS ACLs and information through xattrsDavid Howells2019-05-071-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | The YFS/AuriStor variant of AFS provides more capable ACLs and provides per-volume ACLs and per-file ACLs as well as per-directory ACLs. It also provides some extra information that can be retrieved through four ACLs: (1) afs.yfs.acl The YFS file ACL (not the same format as afs.acl). (2) afs.yfs.vol_acl The YFS volume ACL. (3) afs.yfs.acl_inherited "1" if a file's ACL is inherited from its parent directory, "0" otherwise. (4) afs.yfs.acl_num_cleaned The number of of ACEs removed from the ACL by the server because the PT entries were removed from the PTS database (ie. the subject is no longer known).

* afs: Set correct lock type for the yfs CreateFileMarc Dionne2019-01-101-0/+11
| | | | | | | | | | | | | | | A lock type of 0 is "LockRead", which makes the fileserver record an unintentional read lock on the new file. This will cause problems later on if the file is the subject of locking operations. The correct default value should be -1 ("LockNone"). Fix the operation marshalling code to set the value and provide an enum to symbolise the values whilst we're at it.

* afs: Implement YFS support in the fs clientDavid Howells2018-10-241-0/+106
| | | | | | | | | | Implement support for talking to YFS-variant fileservers in the cache manager and the filesystem client. These implement upgraded services on the same port as their AFS services. YFS fileservers provide expanded capabilities over AFS. Signed-off-by: David Howells <dhowells@redhat.com>
* afs: Implement the YFS cache manager serviceDavid Howells2018-10-241-0/+57
Implement the YFS cache manager service which gives extra capabilities on top of AFS. This is done by listening for an additional service on the same port and indicating that anyone requesting an upgrade should be upgraded to the YFS port. Signed-off-by: David Howells <dhowells@redhat.com>
