However, it fails to account for the SOCK_NONBLOCK and SOCK_CLOEXEC flags that may be or'd onto the type. Thus, a call from the application such as: + +socket(AF_INET, SOCK_STREAM, IPPROTO_TCP) + +will fail to have the type permutation performed, and will be passed to the system as: + +socket(AF_INET, SOCK_DGRAM, IPPROTO_TCP) + +resulting in EPROTONOSUPPORT. + +To fix this, the flag bits should be masked off of the type before the permutation. They also need remapping themselves (since MIPS uses different values for these flags bits). \ No newline at end of file |
