Perhaps try to > fix kernel on 64-bits? Repeatedly calling sendmsg does not work because timeout can't be honored, but repeatedly calling sendmmsg with a count of 1 seems viable (and likewise for recvmmsg but I don't remember if it's as difficult or not; need to look back at archives). As for the const issue, glibc seems to have resolved to remove it. I think we can do the same but perhaps we should document (when we do) that the contents of the timespec after return are unspecified. > > - The if_nameindex/getifaddrs issue > > - LINE_MAX vs sysconf(_SC_LINE_MAX) issue > > - Proposed errc/etc. addition to err.h > > - And error.h? > > - Whether to add default timezone from /etc? > > We just default to ":localtime" if TZ is not defined: > http://git.alpinelinux.org/cgit/aports/plain/main/musl/2001-default-to-localtime-timezone-if-TZ-is-undefined.patch > > and we make /etc/zoneinfo/localtime a symlink to (or a copy of) the > wanted timezone. Works perfect. Yes, that probably works fine, but it may be desirable to have more out-of-the-box compatibility with the way glibc does it for running binaries on non-musl-based systems.

Have you seen the one-line patch to gdb that seems to make everything work fine without it? Rich
