Intercept stpcpy also in ld.so for arm64
|
|
|
f6cbdf |
|
|
|
f6cbdf |
On other arches stpcpy () is intercepted for both libc.so and ld.so.
|
|
|
f6cbdf |
But not on arm64, where it is only intercepted for libc.so.
|
|
|
f6cbdf |
|
|
|
f6cbdf |
This can cause memcheck warnings about the use of stpcpy () in ld.so
|
|
|
f6cbdf |
when called through dlopen () because ld.so contains its own copy of
|
|
|
f6cbdf |
that functions.
|
|
|
f6cbdf |
|
|
|
f6cbdf |
Fix by introducing VG_Z_LD_LINUX_AARCH64_SO_1 (the encoded name of
|
|
|
f6cbdf |
ld.so on arm64) and using that in vg_replace_strmem.c to intercept
|
|
|
f6cbdf |
stpcpy.
