=>Bug Descript

  In Ltp test,case mq_timedsend01 of syscalls is failed.
  Host:x86
  Target:x86
  

=>Reproduce Steps:

1.download ltp test suite from  http://sourceforge.net/projects/ltp/files/LTP%20Source/ltp-20101031/ltp-full-20101031.bz2/download  to your host PC;
2.# cd to ltp-full-20101031;
3.# ./configure;
4.# make && make install;
5.# then you find a folder named ltp in /opt;
6.# run qemux86 with "<-m 512>";
7.# mkdir /opt;
8.# cp ltp folder to qemux86;
9.# cd ltp/testcases/bin;
10.# ./mq_timedsend01  

the following you can find on screen:

mq_timedsend01    0  TINFO  :  (case00) START
EXPECT: return value(ret)=(N >= 0) errno=0 (Success)
RESULT: return value(ret)=       0 errno=0 (Success)

mq_timedsend01    0  TINFO  :  (case01) START
EXPECT: return value(ret)=(N >= 0) errno=0 (Success)
RESULT: return value(ret)=       0 errno=0 (Success)

mq_timedsend01    0  TINFO  :  (case02) START
EXPECT: return value(ret)=(N >= 0) errno=0 (Success)
RESULT: return value(ret)=       0 errno=0 (Success)
mq_timedsend01    0  TINFO  :  (case02) END => OK
mq_timedsend01    0  TINFO  :  (case03) START
EXPECT: return value(ret)=(N >= 0) errno=0 (Success)
RESULT: return value(ret)=       0 errno=0 (Success)
mq_timedsend01    0  TINFO  :  (case03) END => OK
mq_timedsend01    0  TINFO  :  (case04) START
EXPECT: return value(ret)=-1 errno=90 (Message too long)
RESULT: return value(ret)=-1 errno=90 (Message too long)

Comment 1 Bruce Ashfield 2011-03-30 07:52:47 UTC 
Who's our LTP test suite maintainer ? This doesn't look like
a kernel issue, but more than likely a test case problem (the
stack smashing almost always indicates that).

A few questions:
  
  - has the version of LTP changes recently.
  - does this happen on other x86 targets
  - can we disable stack smashing detection and re-run ?
Comment 2 Kunwei Tian 2011-04-18 01:14:00 UTC 
  I found the ltp compiled without toolchain in that test. Tester compiled the ltp of target directly on host.
  If use toolchain to compile ltp of target, then every case running well.
  So mark this bug resolved as invalid.

Verified it.
Comment 4 Kunwei Tian 2011-04-18 01:21:02 UTC 
Ltp download from
http://sourceforge.net/projects/ltp/files/LTP%20Source/ltp-20101031/ltp-full-20101031.bz2/download
