unfs3: fixed the issue that unfsd consumes 100% CPU
The 'accept' function on the socket of unfsd daemon
is always in below error state:
accept(4, 0x7ffd5e6dddc0, [128]) = -1 EINVAL (Invalid argument)
accept(6, 0x7ffd5e6dddc0, [128]) = -1 EINVAL (Invalid argument)
And 'strace -c -p <the pid of unfsd>' shows:
% time seconds usecs/call calls errors syscall
------ ----------- ----------- --------- --------- ----------------
70.87 0.005392 0 513886 513886 accept
29.13 0.002216 0 256943 poll
This error state is in the 'for' loop of the daemon, so it consumes 100%
CPU. The reason is that 'listen' is not called for the TCP socket before
'accept'. Actually the called 'svc_tli_create' from libtirpc will not call
'listen' on a bound socket.
