From 8b2b61e0001281be0dcd3dedc899bf187172fecb Mon Sep 17 00:00:00 2001 From: Segev Finer Date: Wed, 15 Aug 2018 20:46:18 +0300 Subject: mips archs: fix runaway execution if start fn passed to clone returns Call SYS_exit on return from fn in __clone. This is the expected behavior of this function. Without this the child task will crash on return from fn, since it will return to nowhere. --- src/thread/mipsn32/clone.s | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'src/thread/mipsn32') diff --git a/src/thread/mipsn32/clone.s b/src/thread/mipsn32/clone.s index 51035852..ebf5dbea 100644 --- a/src/thread/mipsn32/clone.s +++ b/src/thread/mipsn32/clone.s @@ -26,5 +26,8 @@ __clone: nop 1: lw $25, 0($sp) # function pointer lw $4, 4($sp) # argument pointer - jr $25 # call the user's function + jalr $25 # call the user's function nop + move $4, $2 + li $2, 6058 + syscall -- cgit v1.2.1
