Thomas Gleixner a7b3474cbb x86/irq: Make run_on_irqstack_cond() typesafe ... Sami reported that run_on_irqstack_cond() requires the caller to cast functions to mismatching types, which trips indirect call Control-Flow Integrity (CFI) in Clang. Instead of disabling CFI on that function, provide proper helpers for the three call variants. The actual ASM code stays the same as that is out of reach. [ bp: Fix __run_on_irqstack() prototype to match. ] Fixes: 931b941459 ("x86/entry: Provide helpers for executing on the irqstack") Reported-by: Nathan Chancellor <natechancellor@gmail.com> Reported-by: Sami Tolvanen <samitolvanen@google.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Borislav Petkov <bp@suse.de> Tested-by: Sami Tolvanen <samitolvanen@google.com> Cc: <stable@vger.kernel.org> Link: https://github.com/ClangBuiltLinux/linux/issues/1052 Link: https://lkml.kernel.org/r/87pn6eb5tv.fsf@nanos.tec.linutronix.de		2020-09-22 22:13:34 +02:00
