Subject: [glibc/maskray/lld] Add INADDR_DUMMY from Linux 5.13 to netinet/in.h
Date: Mon, 16 Aug 2021 17:13:28 +0000 (GMT)	[thread overview]
Message-ID: <20210816171328.6F3AC3951866@sourceware.org> (raw)

https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=fb89489636766532902d4a02a08dbb72efed4faf

commit fb89489636766532902d4a02a08dbb72efed4faf
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Thu Aug 5 20:12:56 2021 +0000

    Add INADDR_DUMMY from Linux 5.13 to netinet/in.h
    
    Linux 5.13 adds an INADDR_DUMMY definition; add a corresponding
    definition to glibc's netinet/in.h.  (This isn't strictly a new kernel
    interface, rather a value defined in RFC 7600.)
    
    Tested for x86_64.
