connect() returns EACCES

Hi

Before I start adding printf in the kernel, anyone has an idea why connect() on
an AF_INET socket can return EACCES?

Here is what I get with ktrace: it  makes a AF_INET/SOCK_STREAM socket, calls
setsockopt() for TCP_NODELAY, SO_SNDBUF, SO_RCVBUF, sets O_NONBLOCK on the fd
and attempt to connect:

 18105      1 lmp_crunch CALL  __socket30(2,1,0)
 18105      1 lmp_crunch RET   __socket30 15/0xf
 18105      1 lmp_crunch CALL  setsockopt(0xf,6,1,0x7f7fffffd37c,4)
 18105      1 lmp_crunch RET   setsockopt 0
 18105      1 lmp_crunch CALL  setsockopt(0xf,0xffff,0x1001,0x7f7fea00bba8,4)
 18105      1 lmp_crunch RET   setsockopt 0
 18105      1 lmp_crunch CALL  setsockopt(0xf,0xffff,0x1002,0x7f7fea00bbac,4)
 18105      1 lmp_crunch RET   setsockopt 0
 18105      1 lmp_crunch CALL  fcntl(0xf,3,0)
 18105      1 lmp_crunch RET   fcntl 2
 18105      1 lmp_crunch CALL  fcntl(0xf,4,6)
 18105      1 lmp_crunch RET   fcntl 0
 18105      1 lmp_crunch CALL  connect(0xf,0x7f7fffffd3a0,0x10)
 18105      1 lmp_crunch MISC  mbsoname: [10.110.99.3]
 18105      1 lmp_crunch RET   connect -1 errno 13 Permission denied

What is really odd is that I see many other similar calls in the ktrace that do
not produce EACCES, but EINPROGRESS instead. I do not see where the difference
is.

 18105      1 lmp_crunch CALL  __socket30(2,1,0)
 18105      1 lmp_crunch RET   __socket30 11/0xb
 18105      1 lmp_crunch CALL  setsockopt(0xb,6,1,0x7f7fffffd16c,4)
 18105      1 lmp_crunch RET   setsockopt 0
 18105      1 lmp_crunch CALL  setsockopt(0xb,0xffff,0x1001,0x7f7ff2e0ec68,4)
 18105      1 lmp_crunch RET   setsockopt 0
 18105      1 lmp_crunch CALL  setsockopt(0xb,0xffff,0x1002,0x7f7ff2e0ec6c,4)
 18105      1 lmp_crunch RET   setsockopt 0
 18105      1 lmp_crunch CALL  fcntl(0xb,3,0)
 18105      1 lmp_crunch RET   fcntl 2
 18105      1 lmp_crunch CALL  fcntl(0xb,4,6)
 18105      1 lmp_crunch RET   fcntl 0
 18105      1 lmp_crunch CALL  connect(0xb,0x7f7fffffd1f0,0x10)
 18105      1 lmp_crunch MISC  mbsoname: [10.110.99.3]
 18105      1 lmp_crunch RET   connect -1 errno 36 Operation now in progress
