I wrote “nfm-raw_eth.so” - net filter module,
that works correctly under QNX core 6.3.0;

After installing core 6.3.2
( ntocore-6.3.2-20060811628-nto.sh )
my filter stop working (?!)

I find out, that problem is in resmgr_attach() :

dev_link_ID = resmgr_attach (
resmgr_dpp, // dispatch handle //
&resmgr_attr, // resource manager attrs //
“raw_eth0”, // device name/path //
_FTYPE_ANY, // open type //
0, // flags //
&resmgr_connect_funcs, // connect routines //
&resmgr_io_funcs, // I/O routines //
&fdev_attr[0] ); // handle //

I want to know what to change,
that my filter would work under 6.3.2 and 6.3.0 ?
/I try change dev name, but the problem isn’t there :frowning:

“raw_eth0”, // device name/path //

I have dev name “/dev/raw_eth0”,
but it doesn’t matter;

I found sth:
resmgr_attach() works good if I change parameter:
//resmgr_attr.msg_max_size = 2*1024; - returns error
resmgr_attr.msg_max_size = 1024+512; - ok
resmgr_attr.nparts_max = 1; -ok

…so I can’t send/receive message that size is 2kB ?!
