Subject: [PATCH 2/2] nss: prevent NSS from incorrectly re-using a session
Without this workaround, NSS re-uses a session cache entry despite the
server name does not match. This causes SNI host name to differ from
the actual host name. Consequently, certain servers (e.g. github.com)
respond by 400 to such requests.
