Hi Trond, Anna, Steve,
For kAFS, I'm writing something to allow the in-kernel DNS resolver be able to
ask for a server list (eg. the list of VL servers in an AFS cell) and get back
a list of servers and the addresses associated with each server.
This would be requested by passing an "srv=<version>" option in the callout
info.
The payload handed to the kernel currently looks like something assembled from
the data obtained from a bunch of SRV records that have been further looked up
to A or AAAA.
In the kernel it might get parsed to something like:
struct address {
union {
struct sockaddr_in sin;
struct sockaddr_in6 sin6;
};
};
struct server {
unsigned short port;
unsigned short pref; // From SRV
unsigned short weight; // From SRV
unsigned char ipproto; // IPPROTO_*
unsigned int nr_addrs; // May be 0
struct address *addrs;
};
struct server_list {
unsigned int nr_servers;
struct server servers[];
};
Is this something that NFS or CIFS (or anything else for that matter) could
find useful?
I also have this loading information from a configuration file as a
backup/override of the DNS. Could that also be useful to NFS/CIFS?
