2018-04-09afs: Adjust the directory XDR structuresDavid Howells1-22/+22
Adjust the AFS directory XDR structures in a number of superficial ways: (1) Rename them to all begin afs_xdr_. (2) Use u8 instead of uint8_t. (3) Mark the structures as __packed so they don't get rearranged by the compiler. (4) Rename the hdr member of afs_xdr_dir_block to meta. (5) Rename the pagehdr member of afs_xdr_dir_block to hdr.

2018-04-09afs: Split the directory content defs into a headerDavid Howells1-0/+63
Split the directory content definitions into a header file so that they can be used by multiple .c files. Signed-off-by: David Howells <dhowells@redhat.com>
2018-04-09afs: Rearrange status mappingDavid Howells1-0/+40
Rearrange the AFSFetchStatus to inode attribute mapping code in a number of ways: (1) Use an XDR structure rather than a series of incremented pointer accesses when decoding an AFSFetchStatus object. This allows out-of-order decode. (2) Don't store the if_version value but rather just check it and abort if it's not something we can handle. (3) Store the owner and group in the status record as raw values rather than converting them to kuid/kgid. Do that when they're mapped into i_uid/i_gid. (4) Validate the type and abort code up front and abort if they're wrong. (5) Split the inode attribute setting out into its own function from the XDR decode of an AFSFetchStatus object. This allows it to be called from elsewhere too. (6) Differentiate changes to data from changes to metadata. (7) Use the split-out attribute mapping function from afs_iget().
