[PATCH AUTOSEL 5.10 10/17] kselftest/arm64: Fix validatation termination record after EXTRA_CONTEXT

by Sasha Levin

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit 5c152c2f66f9368394b89ac90dc7483476ef7b88 ] When arm64 signal context data overflows the base struct sigcontext it gets placed in an extra buffer pointed to by a record of type EXTRA_CONTEXT in the base struct sigcontext which is required to be the last record in the base struct sigframe. The current validation code attempts to check this by using GET_RESV_NEXT_HEAD() to step forward from the current record to the next but that is a macro which assumes it is being provided with a struct _aarch64_ctx and uses the size there to skip forward to the next record. Instead validate_extra_context() passes it a struct extra_context which has a separate size field. This compiles but results in us trying to validate a termination record in completely the wrong place, at best failing validation and at worst just segfaulting. Fix this by passing the struct _aarch64_ctx we meant to into the macro.
