Title:
socket creation failure - invalid argument error
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hi, This code is working in 32 bit ubuntu versions 14.04 and 16.04.
Also, this code is working in ubuntu 14.04 64 bit versions.
but it is giving socket creation failure error in ubuntu 64 bit.
(linux-image-3.19.0-25-generic 32/64 bit both working (ubuntu 14.04),
linux-image-4.15.0-45-generic (32 bit working for ubuntu 16.04) and
linux-image-4.15.0-47-generic ubunutu 64 bit gives error. Please
suggest to this issue to run on 64 bit ubuntu 16.04 and other
machines.
This code socket fail and returns -1 : s = socket(AF_INET, SOCK_RAW,
htons(ETH_P_ALL));
