In some situations, the fileserver returns a large negative number
as the length in an FetchData64 call. The old FetchProc code used an int32
to hold this number, and checked length > 0 before attempting to read more
data. The new code uses a uint32, and does while (length), which causes the
cache manage to loop until RX aborts the connection.
This patch restores the old behaviour. length becomes a signed int once more
(and the original 32 bit length from the wire is used, rather than truncating
the 64 bit value), and the conditional checks for > 0.

Instead of returning EINVAL in afs_pathconf when we don't recognize the
pathconf command, return the result of fs_pathconf. fs_pathconf provides
sensible defaults or correctly represents a filesystem not implementing
a particular pathconf cmd; all in-tree (Open)Solaris filesystems call
fs_pathconf for unimplemented commands. Returning EINVAL allegedly
represents that the fileystem does not support pathconf at all.
Also, account for OpenSolaris adding another parameter to
pathconf-related calls.

Using recent NFS clients and servers with the translator under Solaris
causes AFS to be queried for the _PC_FILESIZEBITS pathconf value. Right
now we don't implement it and return EINVAL, causing at least some
modern NFS clients to be unable to mount AFS via the translator on at
least some modern NFS servers.
So, return _PC_FILESIZEBITS as either 32 or 64, depending on whether we
are a 64-bit client or not.

When we read the volume header in order to write it back with a modified

Since we can fail to read the header data if the volume header file
isn't associated with any data (and will be deleted by the salvager),
don't abort. Do still abort if we can't write the data back, since if
the data can be read but not written, other programs may think that the
volume is not being salvaged.

When performing a StoreData or FetchData operation there are
several data validation checks performed to ensure that the
lengths of data obtained with rx_Write and rx_Read are consistent
with the RXAFS_FetchData and RXAFS_StoreData protocol operations.
When an inconsistency is detected the cache manager terminates the
call and returns an error to the caller which is passed to cm_Analyze().
The cache manager was returning -1 as the error code which is
equivalent to RX_CALL_DEAD which in turn will result in the server
being marked down.
This commit makes the following changes:
. add trace logging to permit monitoring this case
. instead of returning -1 return either RX_PROTOCOL_ERROR or RX_EOF
depending on the situation
. in cm_Analyze do not mark a server as down for rx errors other
than RX_CALL_DEAD. Instead, force a new connection and retry
until the request timeout limit is reached.

With kernel 2.6.32 it is now possible for a process to copy its session
keyring to its parent through the use of the KEYCTL_SESSION_TO_PARENT
function of the keyctl syscall.
We can't use this easily from kernel space to cover all calls to
VIOCSETTOK with the setpag flag - we'd need to make a syscall
or have keyctl exported. Instead, a hook is added to ktc_SetToken to
make it honour the AFS_SETTOK_SETPAG flag, which was ineffective with recent
kernels.
This should cover the most common cases (ex: aklog) where this is needed.
The syscall is coded directly to avoid introducing a dependency on the
keyutils library or header files which may not be installed everywhere.
