Hi all, I've written a kernel module that communicates with a remote device via TCP. It works fine while data is passed at less than ~4K per write. Otherwise I receive a "Broken pipe" mistake :( Looks like kernel internal buffers are not being empied while I'm in kernel mode. I tried setsockopt(TCP_NODELAY), sleeping { current->state = INTERRUPTIBLE; current->timeout = jiffies + 10; schedule();} with no success.

GODS! Where is my mistake? How should I make sockets to work? I'd be happy being pointed to some TFM :)

There should be probably less tricky ways to solve my problem, but I just wish to complete this approach.

Thanks in advance,

Mikhail
