hybris: fix crash when gralloc1 not supported on the device (!21) · Merge requests · UBports / Development / Core / Packaging / libhybris

Marius Gripsgard requested to merge xenial_-_fixpro5 into xenial Jun 28, 2020

If HAS_GRALLOC1_HEADER is defined but the device doesn't actually support gralloc1 then gralloc1_open may succeed but the callbacks in the structure are all NULL. Check the module_api_version field before calling gralloc1_open following Loader::Loader() in frameworks/native/libs/ui/Gralloc1.cpp. This fixes a segfault with the binary libs for Samsung herolte.

This fixes https://github.com/ubports/ubuntu-touch/issues/1504
