Eighth Real-Time Linux Workshop
October 12-15, 2006
Lanzhou University - SISE
Hello, everyone.
I'm having fun reading RFC's and looking through linux source code for
implementation examples.
What I'm not able to understand is this piece of code :
union {
struct iphdriph;
charbuf[60];
} tmp_iph;
and corresponding RFC 791 sta

Well, sure... The same can be said of any source code base, for any set

If we consider netchannels as how Van Jackobson discribed them, then
mutext is not needed, since it is impossible to have several readers or
writers. But in socket case even if there is only one userspace
consumer, that lock must be held to protect against bh (or introduce

Small question first:

I do not see redundant syscalls. Is not it expected to send ACKs only
after receiving data as you said? What is the problem?
