Subject: .gnu.hash into text PHDR?
Date: Tue, 17 Nov 2015 15:12:28 +0100	[thread overview]
Message-ID: <564B35CC.3050803@suse.cz> (raw)

Hi,

after
commit 6b7e26547fad7ace3dcb27a5babd2317fb9d1e12

    x86/vdso: Emit a GNU hash

I believe .gnu.hash in arch/x86/entry/vdso/vdso-layout.lds.S should have
":text", right?

Not that it would matter (it is put there automagically), but I noted it
while hunting a new failure inside KVM (host is 4.2 for some time, guest
was upgraded to 4.3 recently). KVM dies when javac invokes gtod:
KVM internal error. Suberror: 1
emulation failure
...
[javac] # C  [linux-vdso.so.1+0xe45]  __vdso_gettimeofday+0x125

which is "movl hpet_page+240(%rip), %eax". Any ideas?

More details at:

thanks,
