linux-toradex.git/Documentation/networking/dccp.rst, branch v6.4-rc3 Linux kernel for Apalis and Colibri modules net: dccp: Add SIOCOUTQ IOCTL support (send buffer fill) 2020-07-23T00:00:37+00:00 Richard Sailer richard_siegfried@systemli.org 2020-07-20T16:06:14+00:00 749c08f8206cdf5cad15d557912898ce22aa55da This adds support for the SIOCOUTQ IOCTL to get the send buffer fill of a DCCP socket, like UDP and TCP sockets already have. Regarding the used data field: DCCP uses per packet sequence numbers, not per byte, so sequence numbers can't be used like in TCP. sk_wmem_queued is not used by DCCP and always 0, even in test on highly congested paths. Therefore this uses sk_wmem_alloc like in UDP. Signed-off-by: Richard Sailer <richard_siegfried@systemli.org> Signed-off-by: David S. Miller <davem@davemloft.net>
