This requires continuous coordination -between them. - -The goal of this commit is to improve the situation for libcs (such as -musl) which are not yet supported and/or do not wish to be explicitly -supported, while not affecting supported libcs. More precisely, with -this commit, unsupported libcs can request the suppression of any -specific uapi definition by defining the correspondings _UAPI_DEF_* -macro as 0. This can fix symbol collisions for them, as long as the -libc headers are included before the uapi headers. Inclusion in the -other order is outside the scope of this commit. - -All infrastructure in order to enable this fallback for unsupported -libcs is already in place, except that libc-compat.h unconditionally -defines all _UAPI_DEF_* macros to 1 for all unsupported libcs so that -any previous definitions are ignored. In order to fix this, this commit -merely makes these definitions conditional. - -This commit together with the musl libc commit - -http://git.musl-libc.org/cgit/musl/commit/?id=04983f2272382af92eb8f8838964ff944fbb8258 - -fixes for example the following compiler errors when <linux/in6.h> is -included after musl's <netinet/in.h>: - -./linux/in6.h:32:8: error: redefinition of 'struct in6_addr' -./linux/in6.h:49:8: error: redefinition of 'struct sockaddr_in6' -./linux/in6.h:59:8: error: redefinition of 'struct ipv6_mreq' - -The comments referencing glibc are still correct, but this file is not -only used for glibc any more. - -Signed-off-by: Felix Janda <felix.ja...@posteo.de> -Reviewed-by: Hauke Mehrtens <ha...@hauke-m.de> ---- - include/uapi/linux/libc-compat.h | 55 +++++++++++++++++++++++++++++++++++++++- - 1 file changed, 54 insertions(+), 1 deletion(-) - ---- a/include/uapi/linux/libc-compat.h -+++ b/include/uapi/linux/libc-compat.h -@@ -167,46 +167,99 @@ - - /* If we did not see any headers from any supported C libraries, - * or we are being included in the kernel, then define everything -- * that we need. */ -+ * that we need.
