Re: [uclibc-ng-devel] __dl_iterate_phdr includes main application binary in list

FWIW, the patch I am currently using is attached. Bogdan On Fri, Mar 22, 2019 at 11:38 AM Bogdan Harjoc <harjoc@gmail.com> wrote:

After building uclibc-1.0.31 with AddressSanitizer enabled (gcc7.3 and 8.2), asan complains at runtime that it's not the first library in the so-list.

With a breakpoint on AsanCheckDynamicRTPrereqs which calls __dl_iterate_phdr, I see the first module that uClibc returns has info->libname = "/home/user/myapp", while on glibc-2.27, libname is an empty string. ASAN depends on seeing this empty string.

Should __dl_iterate_phdr return an empty string here, or is there an alternative to get asan-enabled uClibc toolchains ?

Thanks.
