SIOCGIFADDR, SIOCGIFNETMASK, SOCGIFBRDADDR not working

[cole15601]

This maybe a duplicate of Issue #69, but SIOCGIFADDR et al are not working.

Sample source is:

strcpy(ifr.ifr_name, interface_name ); ifr.if_addr.sa_family=AF_INET; fd = socket(AF_INET,SOCK_DGRAM,IPPROTO_IP); if(ioctl(fd, SIOCGIFBRDADDR, &ifr) != -1) { //do something with the address } else { perror("Error getting IP:"); exit(-1); }

This produces the following output:

Error getting IP: Cannot assign requested address.

@cole15601 - Thanks for reporting this issue. WSL does currently support the SIOCGIFADDR, SIOCGIFNETMASK and SOCGIFBRDADDR , but only AF_INET sockets. Can you please share out full source so that we can repro it here locally?

[cole15601]

@sunilmut - I'm using AF_INET sockets. Test source is attached.
SIOCTests.c.zip

Compile with gcc -g SIOCTests.c and run a.out and it produces the following output:

WSL Tests...
SIOCGIFADDR error : Cannot assign requested address.
SIOCGIFNETMASK error : Cannot assign requested address.
SIOCGIFBRDADDR error : Cannot assign requested address.

WSL Test...
SIOCGIFADDR: eth0 IP addr is 192.168.1.33
SIOCGIFBRDADDR: eth0 IP addr is 192.168.1.255
SIOCGIFNETMASK: eth0 IP addr is 255.255.255.0

Seems it's fixed on insider build 14905.

Great, how does one get that insider build? Any idea when it goes out for public consumption?

[onomatopellan]

For public expected release for next milestone should be March/April.

WSL updates are coming to the Fast ring. To join in you need to go to Settings -> Update & Security -> Windows Insider Program and choose FAST ring. I don't recommend use them on your main PC though. It's better to use a VM or a Test PC/laptop as it can have bugs. (Shutdown StartMenu button doesn't work on build 14905 for example)

Marking this as closed since it is fixed in the Insider builds.
