Re: [irda-users] 2.6.18-rt6 IrDA strangeness
Ok, just tried 20-rt8. Of 3 problems described earlier the first two: non-working syslog(2) and irdadump showing packets only in one direction are now gone. Whereas the third one: On Fri, 2 Mar 2007, Guennadi Liakhovetski wrote: 2. sometimes, especially after a connection break down, the connection is re-established, but the reference side has empty /proc/net/irda/discovery, the reason being a couple of missing packets during re-negotiation: 15:06:43.854376 xid:cmd c62da07d S=6 s=0 (14) 15:06:43.944244 xid:cmd c62da07d S=6 s=1 (14) 15:06:44.034244 xid:cmd c62da07d S=6 s=2 (14) 15:06:44.124245 xid:cmd c62da07d S=6 s=3 (14) 15:06:44.214281 xid:cmd c62da07d S=6 s=4 (14) 15:06:44.304289 xid:cmd c62da07d S=6 s=5 (14) 15:06:44.394282 xid:cmd c62da07d S=6 s=* TESTNODE hint=4400 [ Computer LAN Access ] (25) 15:06:46.864376 xid:cmd c62da07d S=6 s=0 (14) 15:06:46.954286 xid:cmd c62da07d S=6 s=1 (14) 15:06:47.044280 xid:cmd c62da07d S=6 s=2 (14) 15:06:47.134293 xid:cmd c62da07d S=6 s=3 (14) 15:06:47.224281 xid:cmd c62da07d S=6 s=4 (14) 15:06:47.314250 xid:cmd c62da07d S=6 s=5 (14) 15:06:47.404249 xid:cmd c62da07d S=6 s=* TESTNODE hint=4400 [ Computer LAN Access ] (25) 15:06:49.391225 snrm:cmd ca=fe pf=1 c62da07d 0ad5eb46 new-ca=58 (33) 15:06:49.391389 ua:rsp ca=58 pf=1 c62da07d 0ad5eb46 (32) 15:06:49.448100 rr:cmd ca=58 pf=1 nr=0 (2) 15:06:49.448172 rr:rsp ca=58 pf=1 nr=0 (2) 15:06:49.450636 i:cmd ca=58 pf=1 nr=0 ns=0 LM slsap=16 dlsap=00 CONN_CMD (6) 15:06:49.450817 i:rsp ca=58 pf=1 nr=1 ns=0 LM slsap=00 dlsap=16 CONN_RSP (6) I.e., we see 2 discovery packets from TESTNODE, and then the 2.6.18-rt6 host sends directly an SNRM packet without presenting itself first with its nick... Looks like some timers are confused through highres timers?... is still there.

Ok, I also managed to reproduce this with non-rt kernel, so, it's just some incompatibility between 2.4 and 2.6... Might be considered as a nug on the 2.4 reference side.
