dlsym: Make RTLD_NEXT prefer default version definition [BZ #14932] When the first object providing foo defines both foo@v1 and foo@@v2, dlsym(RTLD_NEXT, "foo") returns foo@v1 while dlsym(RTLD_DEFAULT, "foo") returns foo@@v2. The issue is that RTLD_DEFAULT uses the DL_LOOKUP_RETURN_NEWEST flag while RTLD_NEXT doesn't. Fix the RTLD_NEXT branch to use DL_LOOKUP_RETURN_NEWEST. Note: the new behavior matches FreeBSD rtld. Future sanitizers will not need to add versioned interceptors like https://reviews.llvm.org/D96348 Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> 2022-05-27 19:34:49 +00:00			`v1 { };`
