Subject: [PATCH 0/9] sandbox: use native setjmp/longjmp/initjmp implementation by default
Date: Mon, 25 Nov 2024 16:35:14 +0100 [thread overview]
Message-ID: <20241125153523.1411849-1-a.fatoum@pengutronix.de> (raw)
In order to implement initjmp, we have two ways with available
functionality: The sigaltstack we are currently using and
makecontext/swapcontext. makecontext/swapcontext are unfortunately
deprecated in favor of POSIX threads and the sigaltstack runs afoul of
AddressSanitizer when compiled with clang.
This series fixes this by using the already existent assembly
implementations
Ahmad Fatoum (9):
sandbox: asm: support inclusion from sandbox os support code
test: self: setjmp: add simple initial testcase
sandbox: source/invoke um Makefiles provided by host architecture
sandbox: setjmp: mark C version as __weak
sandbox: use native setjmp/longjmp/initjmp implementation by default
sandbox: retire HAVE_ARCH_ASAN
bthread: move asan fiber API into header
test: self: setjmp: make compatible with ASAN
bthread: fix use of ASAN fiber stack switch API
