Hi,
sorry for the late answer, but I was in vacation last week.
After trying out your patches, I've only one thing to mention.
Since you are using c->pollfd[0] for the netlink fd, the pollfd
resize() should use 'sizeof(struct pollfd)' instead of '1' for this
descriptor. Otherwise, you will get some memory corruption.
Best regards
Henry
