Description Thomas Backlund 2014-07-27 19:08:47 CEST 
Advisory:
Updated gcc packages fixes miscompilation and clang++ compatibility

Updated gcc packages fixes the follwoing bugs:
The gcc rtl-optimization sched2 miscompiles syscall sequence wich can 
cause random panic in glibc and kernel (gcc/PR61801)

clang++ fails to find cxxabi.h and cxxabi_tweaks.h during build (mga#13543)




Testscase for miscompilation bug:

testfile:
$ cat exit.i
---
int a, b, c;
void fn1 ()
{
  int d;
  if (fn2 () && !0)
    {
      b = (
          {
            int e;
            fn3 ();
            switch (0)
            default:
            asm volatile("" : "=a"(e) : "0"(a), ""(0));
            e;
          });
      d = b;
    }
  c = d;
}
---

before:
$ gcc -fcompare-debug -O2 -c exit.i
gcc: error: exit.i: -fcompare-debug failure (length)

after:
$ gcc -fcompare-debug -O2 -c exit.i
(no output, exits without errors)


Testcase for clang++

Testfile:
$ cat clang_test.cpp 
---
#include <cxxabi.h>

int main (void)
{
}
---

before:
$ clang++ clang_test.cpp 

clang_test.cpp:1:10: fatal error: 'cxxabi.h' file not found
#include <cxxabi.h>
          ^
1 error generated.


after:
$ clang++ clang_test.cpp 
(no output, exits without errors)

Comment 2 Marja Van Waes 2014-07-27 21:56:50 CEST 
32bits

Does not seem to be fully fixed.

Maybe I shouldn't test when being interupted by many telephone calls (but how could I have known all those calls would come?)

Anyway:
I couldn't do the PoCs before updating, because gcc wasn't installed and libgcc1 had a higher version than the available gcc, though lower than the current one in testing. (didn't dare to downgrade)

Anyway, after installing / updating to
libquadmath0-4.8.2-3.1.mga4.i586.rpm
libgfortran3-4.8.2-3.1.mga4.i586.rpm
libgcc1-4.8.2-3.1.mga4.i586.rpm
libstdc++6-4.8.2-3.1.mga4.i586.rpm
libstdc++-devel-4.8.2-3.1.mga4.i586.rpm
libgomp1-4.8.2-3.1.mga4.i586.rpm
gcc-cpp-4.8.2-3.1.mga4.i586.rpm
gcc-4.8.2-3.1.mga4.i586.rpm

and installing 
clang-3.3-2.mga4.i586.rpm
llvm-3.3-2.mga4.i586.rpm
libclang3.3-3.3-2.mga4.i586.rpm 

I get:
*******************************************************

[u@localhost QAtesting]$ gcc -fcompare-debug -O2 -c exit.i
[u@localhost QAtesting]$ clang++ clang_test.cpp
clang_test.cpp:1:10: fatal error: 'cxxabi.h' file not found
#include <cxxabi.h>
         ^
1 error generated.
[u@localhost QAtesting]$ 

*******************************************************

If I caused that, then I'm blind to what I did wrong :-/

Actually you are hitting: 
https://bugs.mageia.org/show_bug.cgi?id=11805

So I've added a update request for clang/llvm:

That's a relief, tbh :-)

Thanks!

after installing
llvm-3.3-2.1.mga4.i586.rpm
clang-3.3-2.1.mga4.i586.rpm
libclang3.3-3.3-2.1.mga4.i586.rpm
libllvm3.3-3.3-2.1.mga4.i586.rpm

both tests are error-free :-) :

[u@localhost QAtesting]$ clang++ clang_test.cpp
[u@localhost QAtesting]$

so this test also validates that the bug 11805 part of bug 13813 is fixed
Comment 6 Thomas Backlund 2014-07-31 14:15:30 CEST 
This one is being update to squash a security issue
Comment 7 Thomas Backlund 2014-07-31 20:39:41 CEST 
Updated advisory, and now the same fixes are pushed to mga3 too:

Updated gcc packages fixes security issue and other bugs

Updated gcc packages fixes the following security issue:
Multiple integer overflow issues were found in libgfortran, the run-time
support library for the Fortran compiler. These could possibly be used to
crash a Fortran application or cause it to execute arbitrary code.
(CVE-2014-5044)

They also fixes the following bugs:
The gcc rtl-optimization sched2 miscompiles syscall sequence wich can 
cause random panic in glibc and kernel (gcc/PR61801)

clang++ fails to find cxxabi.h and cxxabi_tweaks.h during build (mga#13543)

Comment 8 Marja Van Waes 2014-08-01 13:09:00 CEST 
On Mga3, 64bits, one of the tests fails before updating (I suppose the other problem wasn't present in our Mga 3 version of gcc)

[user@Mga3_64bits QAtesting]$ gcc -fcompare-debug -O2 -c exit.i

Mga4, 64bits:

As shown in comment 1, both tests failed before updating with the packages from updates_testing.

Now, after updating to the very last version:

gcc-4.8.2-3.2.mga4.x86_64.rpm
libgomp1-4.8.2-3.2.mga4.x86_64.rpm
libstdc++-devel-4.8.2-3.2.mga4.x86_64.rpm

libgfortran3-4.8.2-3.2.mga4.x86_64.rpm
gcc-cpp-4.8.2-3.2.mga4.x86_64.rpm

there are no errors while updating.

The tests succeed without problems:
[u@localhost QAtesting]$ gcc -fcompare-debug -O2 -c exit.i
[u@localhost QAtesting]$ clang++ clang_test.cpp
[u@localhost QAtesting]$

Mga4 32bits:

After updating again, now to the very last testing version:

libquadmath0-4.8.2-3.2.mga4.i586.rpm
libgcc1-4.8.2-3.2.mga4.i586.rpm
libstdc++-devel-4.8.2-3.2.mga4.i586.rpm

gcc-cpp-4.8.2-3.2.mga4.i586.rpm
libstdc++6-4.8.2-3.2.mga4.i586.rpm

(there were no errors while updating)

both tests pass without errors:
[u@localhost QAtesting]$ clang++ clang_test.cpp
[u@localhost QAtesting]$ gcc -fcompare-debug -O2 -c exit.i
[u@localhost QAtesting]$

I don't (yet) have a 32 bits Mga3 to test with, can someone else please do that?

Comment 11 David Walser 2014-08-01 16:17:00 CEST 
Testing Mageia 3 i586.

As Marja found on x86_64, the exit.i test was fine before (and after) the update.

However, after the update the clang_test.cpp test still fails.

Tested:
libgfortran3-4.7.2-8.2.mga3
gcc-cpp-4.7.2-8.2.mga3
libstdc++6-4.7.2-8.2.mga3
gcc-c++-4.7.2-8.2.mga3
libquadmath0-4.7.2-8.2.mga3
libgcc1-4.7.2-8.2.mga3
libgomp1-4.7.2-8.2.mga3

That could be for the same reason as why it failed for Mga4 32bits at first:

If so, the same update is needed for Mga3
Comment 13 Thomas Backlund 2014-08-01 18:05:38 CEST 
So right you are Marja :)

llvm-3.2-5.1.mga3 is now heading to updates_testing with the same fixes as done for mga4


as for triggering the gcc miscompilation, it's way harder to do on mga3
wich is why the "gcc -fcompare-debug -O2 -c exit.i" test works before and
after the fix.

The reason for adding the fix on mga3 gcc is that upstream says it's a regression
since gcc-4.5 so I added the fix since gcc is being pushed anyway.

So dont worry if the issue dont trigger, the test still confirms that the affected code for the optimizer is not regressing either :)
Comment 14 David Walser 2014-08-01 19:48:15 CEST 
With the updated clang/llvm, the clang test passes.  Marking OK and validating.

The advisory still needs to be uploaded.

Please push this to core/updates for Mageia 3 and Mageia 4.
