In my application I set SO_RECVTIMEO to 1.5 seconds, then enable SO_ACCEPTF=
ILTER (httpready).
accf_http module is loaded in the kernel.
The problem is that if I connect to the socket but don=E2=80=99t send any d=
ata, the connection remains open indefinitely. The application of course wo=
n=E2=80=99t see a connection since the accept filter don=E2=80=99t see a co=
mplete http request.
Why is this the case? Why doesn=E2=80=99t SO_RECVTIMEO affect the socket? H=
ow to close such connections early?
Also, the documentation says: =E2=80=9CThe optional argument af_arg can be
passed to the accept filter specified by af_name to provide additional
configuration options at attach time.=E2=80=9D
I checked the code of accf_http.c, but from what I see =E2=80=93 the =E2=80=
=9Carg=E2=80=9D value is not used anywhere, nor is there any indication as =
to what that value might be.
Does anyone have any ideas?
