Hello all,
I've written a TPC socket filter that I'm currently using only to pass
all incoming data to the user space and back without any
modifications. That is,
(1) the sf_data_in function copies the data from the mbufs (via
mbuf_copydata) and enqueues them into the control socket,
(2) the user-level process reads the data from the control socket and
simply writes them back,
(3) the ctl_send callback finally injects the data packet in new mbufs
back into the TCP stack.
This seems to work fine most of the time but fails with some SSL
(https) connections (even though it works fine with others). Can
anyone imagine why? Any help would be highly appreciated -- thanks a
lot in advance!
Best, Thorsten
