Subject: vDSO parsing bug?
Hi-
It looks like musl can't handle vDSO images with more than one PT_LOAD
segment. Both glibc and the reference code in
Documentation/vDSO/parse_vdso.c can handle this.
It's not currently an issue, since I don't think that any
architectures provide such a vDSO, but they might want to in the
future.
Also, using the name "linux-gate.so.1" is sort of wrong on x86_64,
where the convention is "linux-vdso.so.1". Wouldn't it be better to
just read the name out of the SONAME header?
