I just want to make sure im understanding this right, only .a files that |
| 27 |
were compiled without -pie will cause issues if you compile the later |
| 28 |
thing that uses the .a with -pie? |
| 29 |
So: |
| 30 |
1) people on hardened profiles are going to be fine no matter what? |
| 31 |
2) only packages that have .a files need to be rebuild? (not -e @world)? |
| 32 |
3) .a are static libs for compiling static binaries right, so nothing |
| 33 |
will break at runtime from the change? only build failures? |
| 34 |
|
| 35 |
I definitley think everyone on gentoo should have PIE and SSP by default |
| 36 |
nowadays. Whats the status of -zrelro -znow on non-hardened? |
| 37 |
|
| 38 |
This might be the kind of thing where a new set of profiles is a good |
| 39 |
idea |
| 40 |
1) hardened would force the flags on, |
| 41 |
2) 13.0 non-hardened would force them off |
| 42 |
3) 17.0 non-hardened would force them on and people have to rebuild when |
| 43 |
they change profiles |
| 44 |
|
| 45 |
Im not sure how the timing of the new profile would work? only make them |
| 46 |
once gcc-6 is stable so everyone does it at once? |
