mount command: full support for AF_INET6 addresses in probe_port()
|
||||||
|
|
||||||
|
Now that probe_port() uses an AF_INET6-capable rpcbind query and RPC ping,
|
||||||
|
finish updating probe_port() to support AF_INET6 addresses fully.

commit 8a5ef964599438ea45f849a0cd1431a0c26bf054

mount command: AF_INET6 support for probe_bothports()
|
||||||
|
|
||||||
|
Introduce an AF_INET6 capable probe_bothports() API. This means replacing
|
||||||
|
"struct sockaddr_in *" arguments with a "struct sockaddr *" and a socklen_t
|
||||||
|
arguments.
|
||||||
|
|
||||||
|
These functions often combine a "struct sockaddr_in" and a "struct pmap" into
|
||||||
|
a single "clnt_addr_t" argument. Instead of modifying "clnt_addr_t" and all
|
||||||
|
the legacy code that uses it, I'm going to create a new probe_bothports() API
|
||||||
|
for the text-based mount command that takes a "struct sockaddr *" and
|
||||||
|
sockaddr length, and leave the existing probe_bothports() interface, which
|
||||||
|
takes "clnt_addr_t" arguments, for legacy use.
