+Subject: [PATCH] uapi libc compat: add fallback for unsupported libcs
21+
+
22+
+libc-compat.h aims to prevent symbol collisions between uapi and libc
23+
+headers for each supported libc. This requires continuous coordination
24+
+between them.
25+
+
26+
+The goal of this commit is to improve the situation for libcs (such as
27+
+musl) which are not yet supported and/or do not wish to be explicitly
28+
+supported, while not affecting supported libcs. More precisely, with
29+
+this commit, unsupported libcs can request the suppression of any
30+
+specific uapi definition by defining the correspondings _UAPI_DEF_*
31+
+macro as 0. This can fix symbol collisions for them, as long as the
32+
+libc headers are included before the uapi headers. Inclusion in the
33+
+other order is outside the scope of this commit.
34+
+
35+
+All infrastructure in order to enable this fallback for unsupported
36+
+libcs is already in place, except that libc-compat.h unconditionally
37+
+defines all _UAPI_DEF_* macros to 1 for all unsupported libcs so that
38+
+any previous definitions are ignored. In order to fix this, this commit
39+
+merely makes these definitions conditional.
40+
+
41+
+This commit together with the musl libc commit
42+
+
43+
+http://git.musl-libc.org/cgit/musl/commit/?id=04983f2272382af92eb8f8838964ff944fbb8258
44+
+
45+
+fixes for example the following compiler errors when <linux/in6.h> is
46+
+included after musl's <netinet/in.h>:
47+
+
48+
+./linux/in6.h:32:8: error: redefinition of 'struct in6_addr'
49+
+./linux/in6.h:49:8: error: redefinition of 'struct sockaddr_in6'
50+
+./linux/in6.h:59:8: error: redefinition of 'struct ipv6_mreq'
51+
+
52+
+The comments referencing glibc are still correct, but this file is not
53+
+only used for glibc any more.
