While doing 'tcpdump gif0' I've got:
- first (no problems here):
lama# tcpdump gif0
tcpdump: syntax error
- second:
rl0: promiscuous mode enabled
lock order reversal
1st 0xc03e10a0 bpf global lock @ /usr/src/sys/net/bpf.c:365
2nd 0xc0c38d6c rl0 @ /usr/src/sys/pci/if_rl.c:1582
rl0: promiscuous mode disabled
NOTE 1: Why tcpdump puts rl0 in promiscuous mode before trying to
evalute the expression?
NOTE 2: (obvious) what about that lock order reversal ?
last cvsuped last night.
