Szabolcs Nagy	29476485f9	aarch64: Ignore GCS property of ld.so ... check_gcs is called for each dependency of a DSO, but the GNU property of the ld.so is not processed so ldso->l_mach.gcs may not be correct. Just assume ld.so is GCS compatible independently of the ELF marking. Reviewed-by: Wilco Dijkstra <Wilco.Dijkstra@arm.com>	2025-01-20 09:36:19 +00:00
Szabolcs Nagy	4d56a5bbd6	aarch64: Handle GCS marking ... - Handle GCS marking - Use l_searchlist.r_list for gcs (allows using the same function for static exe) Co-authored-by: Yury Khrustalev <yury.khrustalev@arm.com> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>	2025-01-20 09:35:56 +00:00
Szabolcs Nagy	01f52b11de	aarch64: Enable GCS in dynamic linked exe ... Use the dynamic linker start code to enable GCS in the dynamic linked case after _dl_start returns and before _dl_start_user which marks the point after which user code may run. Like in the static linked case this ensures that GCS is enabled on a top level stack frame. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>	2025-01-20 09:31:47 +00:00
