Subject: [LTP] [PATCH] fix aio_suspend/3-1
Date: Wed, 27 Jan 2010 14:16:29 +0900	[thread overview]
Message-ID: <4B5FCC2D.7070304@jp.fujitsu.com> (raw)

Hi all

When the aio_suspend/3-1.test ran, SIGSEGV occured with following message
on my x86_64 box.

---
/bin/sh: line 38: 10675 Segmentation fault      ./t0 240 conformance/interfaces/aio_suspend/3-1.test
> $COMPLOG 2>&1
---

This test does not initialize a list[1] array as follows.

---
 40 int main()
...
 88         list[0] = NULL;
 89         list[2] = &aiocb[0];
 90         list[3] = NULL;
 91         list[4] = NULL;
 92         list[5] = &aiocb[1];
 93         list[6] = &aiocb[2];
 94         list[7] = NULL;
...
---

So, list[1] holds a strange value. Since aio_suspend() uses this value as address,
SIGSEGV occurred.

When applying this patch, this test succeeds as follows.

---
conformance/interfaces/aio_suspend/3-1: execution: PASS
---
