afs: Consolidate abort_to_error translators

2017-11-13T15:38:17+00:00

The AFS abort code space is shared across all services, so there's no need
for separate abort_to_error translators for each service.

Consolidate them into a single function and remove the function pointers
for them.

rxrpc: Move the packet.h include file into net/rxrpc/

2017-07-21T10:00:20+00:00

Move the protocol description header file into net/rxrpc/ and rename it to
protocol.h.  It's no longer necessary to expose it as packets are no longer
exposed to kernel services (such as AFS) that use the facility.

The abort codes are transferred to the UAPI header instead as we pass these
back to userspace and also to kernel services.

afs: Invalid op ID should abort with RXGEN_OPCODE

2017-03-16T16:27:47+00:00

When we are given an invalid operation ID, we should abort that with
RXGEN_OPCODE rather than RX_INVALID_OPERATION.

Also map RXGEN_OPCODE to -ENOTSUPP.

kafs: Add more "unified AFS" error codes

2015-04-01T20:36:15+00:00

This should cover the set emitted by viced and the volume server.

AFS: Correctly translate auth error aborts and don't failover in such cases

2009-06-17T04:20:14+00:00

Authentication error abort codes should be translated to appropriate
Linux error codes, rather than all being translated to EREMOTEIO - which
indicates that the server had internal problems.

Additionally, a server shouldn't be marked unavailable and the next
server tried if an authentication error occurs.  This will quickly make
all the servers unavailable to the client.  Instead the error should be
returned straight to the user.

AFS: AFS fixups

2007-05-09T19:30:50+00:00

Make some miscellaneous changes to the AFS filesystem:

 (1) Assert RCU barriers on module exit to make sure RCU has finished with
     callbacks in this module.

 (2) Correctly handle the AFS server returning a zero-length read.

 (3) Split out data zapping calls into one function (afs_zap_data).

 (4) Rename some afs_file_*() functions to afs_*() where they apply to
     non-regular files too.

 (5) Be consistent about the presentation of volume ID:vnode ID in debugging
     output.

[AFS]: Add "directory write" support.

2007-04-26T22:59:35+00:00

Add support for the create, link, symlink, unlink, mkdir, rmdir and
rename VFS operations to the in-kernel AFS filesystem.

Also:

 (1) Fix dentry and inode revalidation.  d_revalidate should only look at
     state of the dentry.  Revalidation of the contents of an inode pointed to
     by a dentry is now separate.

 (2) Fix afs_lookup() to hash negative dentries as well as positive ones.

[AFS]: Clean up the AFS sources

2007-04-26T22:49:28+00:00

Clean up the AFS sources.

Also remove references to AFS keys.  RxRPC keys are used instead.
