The shared library will be installed at:
|
|
|
|
/usr/lib/libhardened_malloc.so
|
|
/usr/lib/libhardened_malloc-light.so
|
|
|
|
It's will NOT become active on its own. To enable it system-wide, you must preload it.
|
|
|
|
1. Test it first! Make sure a normal binary still runs:
|
|
|
|
LD_PRELOAD=/usr/lib/libhardened_malloc.so /bin/true && echo OK
|
|
LD_PRELOAD=/usr/lib/libhardened_malloc-light.so /bin/true && echo OK
|
|
|
|
If that prints OK, the library loads cleanly on this system.
|
|
|
|
2. Enable system-wide by adding this single line to /etc/ld.so.preload
|
|
(create if file doesn't exist):
|
|
|
|
/usr/lib/libhardened_malloc.so
|
|
|
|
for light variant:
|
|
/usr/lib/libhardened_malloc-light.so
|
|
|
|
Per-process alternative (safer to trial): just export LD_PRELOAD as above
|
|
for the programs you want, instead of editing ld.so.preload.
