afs: Fix the non-encryption of calls (4776cab4) · Commits · 戴 / test

Some AFS servers refuse to accept unencrypted traffic, so can't be accessed with kAFS. Set the AF_RXRPC security level to encrypt client calls to deal with this. Note that incoming service calls are set by the remote client and so aren't affected by this. This requires an AF_RXRPC patch to pass the value set by setsockopt to calls begun by the kernel.
