rxrpc: Fix call interruptibility handling
Fix the interruptibility of kernel-initiated client calls so that they're either only interruptible when they're waiting for a call slot to come available or they're not interruptible at all. Either way, they're not interruptible during transmission. This should help prevent StoreData calls from being interrupted when writeback is in progress. It doesn't, however, handle interruption during the receive phase. Userspace-initiated calls are still interruptable. After the signal has been handled, sendmsg() will return the amount of data copied out of the buffer and userspace can perform another sendmsg() call to continue transmission. Fixes: bc5e3a546d55 ("rxrpc: Use MSG_WAITALL to tell sendmsg() to temporarily ignore signals") Signed-off-by: David Howells <dhowells@redhat.com>
