Patch NSIS so that it's installer stubs, produced at NSIS build time,
|
||
|
|
do not contain .reloc sections, which will exist by default when using
|
||
|
|
binutils/ld 2.36+.
|
||
|
|
|
||
|
|
This ultimately fixes an issue when running the installer with the
|
||
|
|
"Force randomization for images (Mandatory ASLR)" setting active.
|
||
|
|
|
||
|
|
This patch has not yet been sent upstream, because it's not clear if this
|
||
|
|
is the best fix, for the underlying issue, which seems to be that makensis
|
||
|
|
doesn't account for .reloc sections when it builds installers.
|
||
|
|
|
||
|
|
The existence of a reloc section shouldn't be a problem, and, if anything,
|
||
|
|
is actually a requirement for working ASLR. All other Windows binaries we
|
||
|
|
produce contain them, and function correctly when under the same
|
||
|
|
"Force randomization for images (Mandatory ASLR)" setting.
