SubjectRe: [PATCH] net/ipv6: Fix a test against 'ipv6_find_idev()' return value
From: Christophe JAILLET <>
Date: Fri, 28 Dec 2018 23:28:21 +0100

> 'ipv6_find_idev()' returns NULL on error, not an error pointer.
> Update the test accordingly and return -ENOBUFS, as already done in
> 'addrconf_add_dev()', if NULL is returned.
> Fixes: ("ipv6: allow userspace to add IFA_F_OPTIMISTIC addresses")
> Signed-off-by: Christophe JAILLET <>

Please provide the SHA1_ID in the Fixes: tag next time, I fixed it up
