Here are some patches that add a few things for kernel services to use: (1) Allow service upgrade to be requested and allow the resultant actual service ID to be obtained. (2) Allow the RTT time of a call to be obtained. (3) Allow a kernel service to find out if a call is still alive on a server between transmitting a request and getting the reply. (4) Allow data transmission to ignore signals if transmission progress is being made in reasonable time. This is also usable by userspace by passing MSG_WAITALL to sendmsg()[*]. [*] I'm not sure this is the right interface for this or whether a sockopt should be used instead. The patches can be found here also: http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=rxrpc-next Tagged thusly: git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git rxrpc-next-20171018 David --- David Howells (3): rxrpc: Support service upgrade from a kernel service rxrpc: Provide functions for allowing cleaner handling of signals rxrpc: Use MSG_WAITALL to tell sendmsg() to temporarily ignore signals Documentation/networking/rxrpc.txt | 53 +++++++++++++++++- fs/afs/internal.h | 1 fs/afs/rxrpc.c | 42 +++++++++++--- include/net/af_rxrpc.h | 7 ++ net/rxrpc/af_rxrpc.c | 24 ++++++++ net/rxrpc/peer_object.c | 13 ++++ net/rxrpc/recvmsg.c | 5 +- net/rxrpc/sendmsg.c | 107 +++++++++++++++++++++++++++--------- 8 files changed, 211 insertions(+), 41 deletions(-)
