hello,
one of my friends wants to discuss a netfilter problem with
you! thx!
-------------------------------------------------------------
hi,
I am a student, I think that skb has all the information
that is needed for sending and receiving.So I get the skb
pointer at NF_IP_POST_ROUTING, put it in a chain organized
by myself (I use a spinlock_t lock to control the access of
the chain, I named it mylock), and return NF_STOLEN.
I make a tq_timer task to start ip_finish_output2(I export
it from kernel),ip_finish_output2 use the skb from my chain.I
can make ftp run ok for almost 1 hour, but then the system will
carsh with this information:
ds:0018 es:0018 ss:0018
process swapper(pid:0, stackpage = c0265000)
stack: c01a07ea c173a088 ...........
call trace:[<c01a07ea>] [<c01a156d>]......
code: 0f 0b 89 7c 24 04 b8 03 00 00 00......
<0>kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing!
I want to know why I count run for some time but could not
go on for a long time . Does it possible to transmit data by the
way and how to do?thanks very much!
best regard
Chen Wei
