[PATCH 2/3] NFSD: Support AF_INET6 in svc_addsock() function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Aime Le Rouzic <aime.le-rouzic@xxxxxxxx>

Relax the address family check at the top of svc_addsock() to allow AF_INET6
listener sockets to be specified via /proc/fs/nfsd/portlist.
