Hi;
Compiling LTP with "-fstack-protector -D_FORTIFY_SOURCE=2" ends up with some
test failures like following;
buildhouse ltp # testcases/bin/getgroups01
*** buffer overflow detected ***: testcases/bin/getgroups01 terminated
getgroups01 1 BROK : Unexpected signal 6 received.
getgroups01 2 BROK : Remaining cases broken
getgroups01 3 BROK : Remaining cases broken
getgroups01 4 BROK : Remaining cases broken
caused by @getgroups01.c
[...]
/*
* Check to see if getgroups() fails on erraneous condition.
*/
TEST( getgroups(-1,gidset) );
[...]
buildhouse ltp # testcases/bin/readlink03
readlink03 1 PASS : readlink(), No Search permissions to process,
returned errno 13
readlink03 2 PASS : readlink(), No Search permissions to process,
returned errno 13
*** buffer overflow detected ***: testcases/bin/readlink03 terminated
readlink03 3 BROK : Unexpected signal 6 received.
readlink03 4 BROK : Remaining cases broken
readlink03 5 BROK : Remaining cases broken
buildhouse ltp # testcases/bin/open08
*** invalid open call: O_CREAT without mode ***: testcases/bin/open08 terminated
open08 1 BROK : Unexpected signal 6 received.
open08 2 BROK : Remaining cases broken
open08 3 BROK : Remaining cases broken
open08 4 BROK : Remaining cases broken
open08 5 BROK : Remaining cases broken
open08 6 BROK : Remaining cases broken
And even after some time machine goes down and hard reboot neeeded, following
output is failed tests list but machine freezes before LTP completes its tests
so i'm not sure which test causes lockup.
buildhouse ltp # cat output/LTP_RUN_ON-2008_Nis_13-23h_20m_37s.failed
getgroups01 getgroups01
getgroups04 getgroups04

inode01 inode01
fsx-linux export TCbin=$LTPROOT/testcases/kernel/fs/fsx-linux;fsxtest02 10000
But removing "-fstack-protector -D_FORTIFY_SOURCE=2" from FLAGS makes all tests
PASS on very same machine without a problem.
So what is the correct way to handle this situation (removing
"-fstack-protector -D_FORTIFY_SOURCE=2" from compile flags using Makefile etc.
or correcting tests to conform FORTIFY_SOURCE cases)? Any hints will be
appreciated.
Cheers
