  • 1a4240f47   DNS: Separate out CIFS DNS Resolver code ... Browse Code »

    Separate out the DNS resolver key type from the CIFS filesystem into its own
    module so that it can be made available for general use, including the AFS
    filesystem module.

    This facility makes it possible for the kernel to upcall to userspace to have
    it issue DNS requests, package up the replies and present them to the kernel
    in a useful form. The kernel is then able to cache the DNS replies as keys
    can be retained in keyrings.

    Resolver keys are of type "dns_resolver" and have a case-insensitive
    description that is of the form "[:]". The optional
    indicates the particular DNS lookup and packaging that's required. The
    is the query to be made.

    If isn't given, a basic hostname to IP address lookup is made, and the
    result is stored in the key in the form of a printable string consisting of a
    comma-separated list of IPv4 and IPv6 addresses.

    This key type is supported by userspace helpers driven from /sbin/request-key
    and configured through /etc/request-key.conf. The cifs.upcall utility is
    invoked for UNC path server name to IP address resolution.

    The CIFS functionality is encapsulated by the dns_resolve_unc_to_ip() function,
    which is used to resolve a UNC path to an IP address for CIFS filesystem. This
    part remains in the CIFS module for now.

    See the added Documentation/networking/dns_resolver.txt for more information.

  • 76181c134   KEYS: Make request_key() and co fundamentally asynchronous ... Browse Code »

    Make request_key() and co fundamentally asynchronous to make it easier for
    NFS to make use of them. There are now accessor functions that do
    asynchronous constructions, a wait function to wait for construction to
    complete, and a completion function for the key type to indicate completion
    of construction.

    Note that the construction queue is now gone. Instead, keys under
    construction are linked in to the appropriate keyring in advance, and that
    anyone encountering one must wait for it to be complete before they can use
    it. This is done automatically for userspace.

    The following auxiliary changes are also made:

    (1) Key type implementation stuff is split from linux/key.h into
    linux/key-type.h.

    (2) AF_RXRPC provides a way to allocate null rxrpc-type keys so that AFS does
    not need to call key_instantiate_and_link() directly.

    (3) Adjust the debugging macros so that they're -Wformat checked even if
    they are disabled, and make it so they can be enabled simply by defining
    __KDEBUG to be consistent with other code of mine.

    (3) Documentation.

  • 17926a793   [AF_RXRPC]: Provide secure RxRPC sockets for use by userspace and kernel both ... Browse Code »

    Provide AF_RXRPC sockets that can be used to talk to AFS servers, or serve
    answers to AFS clients. KerberosIV security is fully supported. The patches
    and some example test programs can be found in:

    http://people.redhat.com/~dhowells/rxrpc/

    This will eventually replace the old implementation of kernel-only RxRPC
    currently resident in net/rxrpc/.

  • 31204ed92   [PATCH] keys: discard the contents of a key on revocation ... Browse Code »

    Cause the keys linked to a keyring to be unlinked from it when revoked and it
    causes the data attached to a user-defined key to be discarded when revoked.

    This frees up most of the quota a key occupied at that point, rather than
    waiting for the key to actually be destroyed.

  • 2aa349f6e   [PATCH] Keys: Export user-defined keyring operations ... Browse Code »

    Export user-defined key operations so that those who wish to define their
    own key type based on the user-defined key operations may do so (as has
    been requested).

    The header file created has been placed into include/keys/user-type.h, thus
    creating a directory where other key types may also be placed. Any
    objections to doing this?
