MSG_EOR flag

[Henner Eisen <eis@xxxxxxxxxxxxx>]

Hi,

somewhere in 2.3.x, sock_write() was changed to call proto_ops.sendmsg() of
SOCK_SEQPACK sockets with MSG_EOR flag set (which broke some protocols first).

My questions now are: how should the MSG_EOR be used consistently?

Should sockets which do not support sending fragments via sendmsg refuse
to accept sendmsg without MSG_EOR set? This seems consistent, but can cause
compatibility problems with 2.2.x kernels.

How should the MSG_EOR flag affect recvmsg()?
