Subject: [PATCH] [downstream] Adjust build configuration
|
|
|
afd354 |
|
|
|
afd354 |
Build binaries in this package as RELRO PIEs, libraries as partial RELRO,
|
|
|
afd354 |
and install shared libraries with the execute bit set on them. Prune out
|
|
|
afd354 |
the -L/usr/lib* and PIE flags where they might leak out and affect
|
|
|
afd354 |
apps which just want to link with the libraries. FIXME: needs to check and
|
|
|
afd354 |
not just assume that the compiler supports using these flags.

(cherry picked from commit 92508996ed4c69fa6f5cf855fdf10f34cfa07ec9)
