since netdb should only be called from userspace

4addf6c308 libc/netdb: query IPv6 first than IPv4
since some host have multiple IPv4 address, the dns cache may fill in all
Ipv4 address and refuse to accept any IPv6 address if we query IPv4 first

23aa2839c3 libs/libc/netdb/lib_dnsquery.c: harden against DNS spoofing. This commit implements most of the RFC 5452 guidelines for making DNS more resilient. We now verify response matches against what was queried and use unpredictable query IDs. It is also checked that response come from correct DNS server. Also fixes a buffer overflow when querying hostnames longer than CONFIG_NETDB_DNSCLIENT_NAMESIZE. 2018-11-16 06:56:45 -06:00

cf99fb40c9 This commit moves all of the libraries under a common directory called libs/. This most certainly break libcxx and uClibc++ for now.
Squashed commit of the following:

    libs/libxx:  Fix some confusing in naming.  If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
    libs/:  Fix paths in moved library directories.
    libs:  Brute force move of libc, libnx, and libxx to libs.  Cannot yet build it in that configuration.
