Like you found below, it can be avoided using vanilla GCC. |
| 9 |
That is why I still only have mplayer-1.0_rc1-r2, that one compiled |
| 10 |
okay. |

Not a problem with hardened. |

| 21 |
Meanwhile, downgrade to 5.03, that one works. |

what card and which drivers? |
| 26 |
I have an old card that is not supported by drivers >= 1.0.9700, so |
| 27 |
... scratch that, I didn't notice that the versioning scheme changed. |

This really does not sound like a hardened issue... I need to upgrade |
| 37 |
my drivers to the 96.* to see if I can reproduce your problem, but |
| 38 |
with 1.0.8776 (from two years ago) I definitely do not have your |
| 39 |
problem. |

glxinfo segfaulting is expected. Do you have chpax/paxctl installed? There |
| 45 |
are a metric shitload of stuff that will run afoul of pax on hardened. |
| 46 |
A quick list from my /etc/conf.d/chpax has (admittedly, this is info |
| 47 |
that is two years old, since chpax is obsolete and hasn't been |
| 48 |
updated) |
| 49 |
|
| 50 |
java, wine, xorg, xine, openoffice, mplayer, mozilla, firefox, |
| 51 |
glxinfo, glxgears, ut2004, skype |
| 52 |
|
| 53 |
glxinfo has problem with mprotect. Check your system log, there should |
| 54 |
be something to that effect when your hardened system shuts glxinfo |
| 55 |
down. |
| 56 |
|
| 57 |
I have my entire system on the |
| 58 |
hardened profile (including X and nvidia [yes, despite the warnings of |
| 59 |
the hardened team about nvidia]) and no problems. My guess is that |
| 60 |
your problem with GLX lies somewhere else. |

Don't know. On the wiki there is a way to switch CFLAGS, don't know if |
| 67 |
something like that can be used to strip SSP and/or PIC flags from the |
| 68 |
hardened. |
