Re: [libvirt] [PATCH 06/12] Integrate TLS/SASL directly into the socket APIs

This extends the basic virNetSocket APIs to allow them to have a handle to the TLS/SASL session objects, once established. This ensures that any data reads/writes are automagically passed through the TLS/SASL encryption layers if required. * src/rpc/virnetsocket.c, src/rpc/virnetsocket.h: Wire up SASL/TLS encryption --- src/rpc/virnetsocket.c | 274 +++++++++++++++++++++++++++++++++++++++++++++++- src/rpc/virnetsocket.h | 11 ++ 2 files changed, 282 insertions(+), 3 deletions(-)
