Mixin Argument Socket

We will categorize and list all available Mixins so that manual creation is unnecessary, and we will keep the list updated based on publicly available resources. We will also provide specific usage recommendations to ensure validity, particularly when the Mixins we offer are limited in scope.

Argument Socket

AF_INET
AF_INET6
AF_UNIX
AF_UNSPEC

SOCK_STREAM
SOCK_DGRAM
SOCK_RAW
SOCK_SEQPACKET

IPPROTO_IP
IPPROTO_ICMP
IPPROTO_TCP
IPPROTO_UDP
IPPROTO_RAW

Usage: sock.socket(sock.AF_INET, sock.SOCK_STREAM, sock.IPPROTO_IP)
Description: For RAW users, you can create manual SYN, ACK, etc. handshakes independently, because CRS only bridges communication with the kernel.

IMPORTANT

If you are using a Mixin that is not available, we recommend that you add is here And here Alternatively, you can implement this yourself within the modules you create; ensure that you send an integer rather than a string. This is because the CRS validates input data: if the input is not found in the list, it returns a default value, whereas if the input is an integer, it returns the same value as the input.
