Add the __no_stack_protector macro as an alias for __attribute__((no_stack_protector)), which prevents the generation by the compiler of the stack protection code. Signed-off-by: Jerome Forissier <[email protected]>
Apply the __no_stack_protector attribute to the first C function called following the TA entry point (i.e., __ta_entry(), or for the special case of ARM32, __ta_entry_c()). This is required because __stack_chk_guard is initialized in this very function, therefore stack protection cannot be assumed to be functional at this point. Fixes a TA crash on QEMUv7 with Clang 18.1.7 [1]. Link: OP-TEE#7047 [1] Signed-off-by: Jerome Forissier <[email protected]>
