Over the years, the code that manages the TCP connections has accumulated a lot of cargo cult code, largely in due to the fact that the RPC duplicate replay caches do a lot of stuff that is not really sanctioned by the IETF spec; the main unsanctioned thing being port reuse. This patchset is an attempt to clean up the mess, and replace our current hacky code to disconnect sockets using the TCP RST mechanism with a more robust version that uses the SO_REUSEPORT socket option to ensure that we can reuse the socket ports even if they are stuck in TIME_WAIT. Trond Myklebust (11): SUNRPC: Set SO_REUSEPORT socket option for TCP connections SUNRPC: Handle EADDRINUSE on connect SUNRPC: Do not clear the source port in xs_reset_transport SUNRPC: Ensure xs_reset_transport() resets the close connection flags SUNRPC: Add helpers to prevent socket create from racing SUNRPC: TCP/UDP always close the old socket before reconnecting SUNRPC: Remove TCP client connection reset hack SUNRPC: Kill the special TCP close mechanisms SUNRPC: Remove TCP socket linger code SUNRPC: Cleanup to remove remaining uses of XPRT_CONNECTION_ABORT SUNRPC: Remove the redundant XPRT_CONNECTION_CLOSE flag include/linux/sunrpc/xprt.h | 6 +- net/sunrpc/clnt.c | 3 + net/sunrpc/xprt.c | 38 +++++++- net/sunrpc/xprtsock.c | 230 ++++++++++++++------------------------------ 4 files changed, 111 insertions(+), 166 deletions(-) -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
