Android L added a libsigchain library it LD_PRELOADs. That library exposes a different sigaction than libc's. It's used for ART. faulty.lib gets its sigaction from libsigchain, but after bug 874708, the libraries it loads simply use libc's sigaction, assuming it would be the hooked one. In turn, this means libraries loaded by faulty.lib may override faulty.lib's handler, which is definitely not the intent. This essentially restores some of the code that bug 874708 removed. An alternative fix would be to add support for LD_PRELOAD, but that has more implications and feels more risky. This could be done, if necessary, as a followup. |
