musl - an implementation of the standard library for Linux-based systems

the size of 512 is not sufficient to get at least one address in the worst case where the name is at or near max length and resolves to a CNAME at or near max length. prior to tcp fallback, there was nothing we could do about this case anyway, but now it's fixable. the new limit 768 is chosen so as to admit roughly the number of addresses with a worst-case CNAME as could fit for a worst-case name that's not a CNAME in the old 512-byte limit. outside of this worst-case, the number of addresses that might be obtained is increased. MAXADDRS (48) was originally chosen as an upper bound on the combined number of A and AAAA records that could fit in 512-byte packets (31 and 17, respectively). it is not increased at this time. so as to prevent a situation where the A records consume almost all of these slots (at 768 bytes, a "best-case" name can fit almost 47 A records), the order of parsing is swapped to process AAAA first. this ensures roughly half of the slots are available to each address family. |

musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
