Daniel Bertalan bd6dc5ccec Meta+LibC: Don't allow text relocations in SerenityOS libraries ... The `-z,text` linker flag causes the linker to reject shared libraries and PIE executables that have textrels. Our code mostly did not use these except in one place in LibC, which is changed in this commit. This makes GNU ld match LLD's behavior, which has this option enabled by default. TEXTRELs pose a security risk, as performing these relocations require executable pages to be written to by the dynamic linker. This can significantly weaken W^X hardening mitigations. Note that after this change, TEXTRELs can still be used in ports, as the dynamic loader code is not changed. There are also uses of it in the kernel, removing which are outside the scope of this PR. To allow those, `-z,notext` is added.		2021-08-18 18:01:22 +02:00
