Hi Trond-
This set of patches, for 2.6.32, introduces a set of exported
functions to sunrpc.ko for converting between a socket address and
either a standard presentation address string or an RPC universal
address.
The universal address functions will be used to encode and decode
RPCB_FOO and NFSv4 SETCLIENTID arguments. The other functions are
part of a previous promise to deliver shared functions that can be
used by upper-layer protocols to display and manipulate IP
addresses.
The kernel's current printf formatters for IP addresses (%pI4 and
%pI6) were designed specifically for kernel to user-space APIs that
require a particular string format for socket addresses. Thus they
are somewhat limited for the purposes of RPC. The formatter for IPv6
addresses, %pI6, does not support short-handing (see RFC 4291) or
IPv6 scope IDs. Also, these printf formatters are unique per address
family, so separate formatter strings are required for printing
AF_INET and AF_INET6 addresses.
These patches have seen light testing here, and are also available
in the cel-2.6.git linux.nfs.org repository under cel-ipv6-07152009.
The last patch in this series might go to Bruce, but it depends on
the previous 9 here.
