c7640f8346 monitor: fix integer comparison error (clang) 
Though the documentation for NLMSG_OK uses an int type for the length
the actual check is based on nlmsghdr->nlmsg_len which is a 32 bit
unsigned integer. Clang was complaining about one call in nlmon.c
because nlmsg_len was int type. Every other usage in nlmon.c uses
a uint32_t, so use that both for consistency and to fix the warning.

monitor/nlmon.c:7998:29: error: comparison of integers of different
		signs: '__u32' (aka 'unsigned int') and 'int'
		[-Werror,-Wsign-compare]
        for (nlmsg = iov.iov_base; NLMSG_OK(nlmsg, nlmsg_len);
                                   ^~~~~~~~~~~~~~~~~~~~~~~~~~
/usr/include/linux/netlink.h💯24: note: expanded from macro 'NLMSG_OK'
                           (nlh)->nlmsg_len <= (len))

1cd3cd2eb9 iwmon: add support for new key format 
The kernel has two ways SET_KEY/NEW_KEY messages can be structured.
This implements parsers for the new key format.

98e1d38056 monitor: Fix crash 
NLMSG_OK and NLMSG_NEXT expect to operate on nlmsg_len which is an int
(signed type).  The current code uses an unsigned type which means that
it cannot detect underflows.  Such underflows can happen when NLMSG_NEXT
tries to advance nlmsg_len by a number of bytes (due to alignment) which
are greater than the current nlmsg_len itself.  This causes iwmon to
crash on certain messages.
