Subject: [PATCH] tests: When building .so from -O asm output mark as
|
||
|
|
non-executable stack
|
||
|
|
|
||
|
|
For certain tests, we take the output from dtc -O asm and build it into
|
||
|
|
a .so shared library which we then dlopen() for further tests. Because we
|
||
|
|
don't mark it otherwise, it's treated as requiring an executable stack,
|
||
|
|
which dlopen() refuses to open as of glibc-2.41.
|
||
|
|
|
||
|
|
Of course, the library is pure data, no code, so it certainly doesn't need
|
||
|
|
an executable stack. Add the -znoexecstack linker option to avoid the
|
||
|
|
error.
