The SCM_TIMESTAMPING_PKTINFO macro is missing from the socket.h header that musl libc provides as of version 1.1.16 that we currently use in Buildroot. Patch the code to add this macro locally until we update musl.

Subject: [PATCH] ntp: fix build with musl libc
|
|
|
|
The configure script enables HAVE_LINUX_TIMESTAMPING_OPT_PKTINFO based
|
|
on the existence of struct scm_ts_pktinfo and
|
|
SOF_TIMESTAMPING_OPT_PKTINFO that were introduced in Linux kernel v4.13
|
|
in the linux/net_tstamp.h kernel header. But this feature also requires
|
|
SCM_TIMESTAMPING_PKTINFO that is defined in the socket.h header. musl
|
|
libc provides its own version of socket.h, and as of musl version 1.1.16
|
|
this macro is missing. Define this macro in the code as a temporary
|
|
measure until musl is updated to its latest version.
