lockd: Add helper to sanity check incoming NOTIFY requests

2008-10-03T21:02:35+00:00

lockd accepts SM_NOTIFY calls only from a privileged process on the
local system.  If lockd uses an AF_INET6 listener, the sender's address
(ie the local rpc.statd) will be the IPv6 loopback address, not the
IPv4 loopback address.

Make sure the privilege test in nlmsvc_proc_sm_notify() and
nlm4svc_proc_sm_notify() works for both AF_INET and AF_INET6 family
addresses by refactoring the test into a helper and adding support for
IPv6 addresses.

lockd: change nlmclnt_grant() to take a "struct sockaddr *"

2008-10-03T21:02:35+00:00

Adjust the signature and callers of nlmclnt_grant() to pass a "struct
sockaddr *" instead of a "struct sockaddr_in *" in order to support IPv6
addresses.

lockd: Adjust nlmsvc_lookup_host() to accomodate AF_INET6 addresses

2008-10-03T21:02:35+00:00

Fix up nlmsvc_lookup_host() to pass AF_INET6 source addresses to
nlm_lookup_host().

lockd: Adjust nlmclnt_lookup_host() signature to accomodate non-AF_INET

2008-10-03T21:02:34+00:00

Pass a struct sockaddr * and a length to nlmclnt_lookup_host() to
accomodate non-AF_INET family addresses.

As a side benefit, eliminate the hostname_len argument, as the hostname
is always NUL-terminated.

lockd: move grace period checks to common code

2008-10-03T20:19:19+00:00

Do all the grace period checks in svclock.c.  This simplifies the code a
bit, and will ease some later changes.

lockd: Teach nlm_cmp_addr() to support AF_INET6 addresses

2008-09-29T22:13:39+00:00

Update the nlm_cmp_addr() helper to support AF_INET6 as well as AF_INET
addresses.  New version takes two "struct sockaddr *" arguments instead of
"struct sockaddr_in *" arguments.

NSM: Use sockaddr_storage for sm_addr field

2008-09-29T22:13:39+00:00

To store larger addresses in the nsm_handle structure, make sm_addr a
sockaddr_storage.

lockd: Use sockaddr_storage for h_saddr field

2008-09-29T22:13:39+00:00

To store larger addresses in the nlm_host structure, make h_saddr a
sockaddr_storage.  And let's call it something more self-explanatory:
"saddr" could easily be mistaken for "server address".

lockd: Use sockaddr_storage + length for h_addr field

2008-09-29T22:13:39+00:00

To store larger addresses in the nlm_host structure, make h_addr a
sockaddr_storage, and add an address length field.

lockd: address-family independent printable addresses

2008-09-29T22:13:38+00:00

Knowing which source address is used for communicating with remote NLM
services can be helpful for debugging configuration problems on hosts
with multiple addresses.

Keep the dprintk debugging here, but adapt it so it displays AF_INET6
addresses properly.  There are also a couple of dprintk clean-ups as
well.

At some point we will aggregate the helpers that display presentation
format addresses into a single set of shared helpers.
