4 | Subject: [PATCH] Propagate GLIBC_TUNABLES in setxid binaries |
5 | |
6 | GLIBC_TUNABLES scrubbing happens earlier than envvar scrubbing and some |
7 | tunables are required to propagate past setxid boundary, like their |
8 | env_alias. Rely on tunable scrubbing to clean out GLIBC_TUNABLES like |
9 | before, restoring behaviour in glibc 2.37 and earlier. |
