From 2c9120f3a86a809518ece1787d76ae07dd01e01b Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 20 Feb 2018 14:16:29 +0000 Subject: arm64: signal: Make force_signal_inject more robust force_signal_inject is a little flakey: * It only knows about SIGILL and SIGSEGV, so can potentially deliver other signals based on a partially initialised siginfo_t * It sets si_addr to point at the PC for SIGSEGV * It always operates on current, so doesn't need the regs argument This patch fixes these issues by always assigning the si_addr field to the address parameter of the function and updates the callers (including those that indirectly call via arm64_notify_segfault) accordingly.
