rtld calls functions in the .init_array section one at a time, until it finds a distinguished sentinel value. The C runtime does the same thing (in crtend.c). However, that checks for the sentinel -1 and not 1. If one is using a linker that unifies .ctors and .init_array, then rtld will miss the sentinel value. I believe the author of this code intended to write -1 instead of 1. Indeed, changing the code to also check for -1 prevents rtld from attempting to call a non-existent function. The same is true of .dtors and .fini_array. Signed-off-by: Daniel Levin <[email protected]> Reviewed by: kib MFC after: 3 days Pull Request: https://github.com/freebsd/freebsd-src/pull/2270
