| message |
For multicast and broadcast packets udp_input() traverses the loop of all UDP PCBs. From there it calls udp_sbappend() while holding the UDP table mutex. This ends in sorwakeup() where we finally grab the kernel lock while holding a mutex. Witness detects this misuse. Use the same solution as for PCB notify. Collect the affected PCBs in a temporary list. The list is protected by exclusive net lock. Reported-by: [email protected] OK sashan@ |
