SubjectRe: [PATCH] net/compat: fix dev_ifsioc emulation corner cases
From: Arnd Bergmann <>
Date: Wed, 11 Nov 2009 14:39:40 +0100

> Handling for SIOCSHWTSTAMP is broken on architectures
> with a split user/kernel address space like s390,
> because it passes a real user pointer while using
> set_fs(KERNEL_DS).
> A similar problem might arise the next time somebody
> adds code to dev_ifsioc.
> Split up dev_ifsioc into three separate functions for
> SIOCSHWTSTAMP, SIOC*IFMAP and all other numbers so
> we can get rid of set_fs in all potentially affected
> cases.
> Signed-off-by: Arnd Bergmann <>


> Resending this one as well, rebased to current net-next.
> Please tell me if you want a backport to 2.6.32 or -stable
> for this one.
