I also tried to reproduce the mentioned failure in a clean Xenial
container with no success. Since this is an old bug and no one replied
to it for years I am removing the server-next tag.

Hi KJH,
I appreciate all your help and I really think Jon is really trying to help.
And also from the source I agree.
But the rules dictate that one is supposed to verify the issue and the fix of
it.
So a question might be "how often is often" and "how long is long".
Because for me as well e.g.
The thing is, I rely on 'ip' a lot. So, not wanting to have to rely on
code I knew was buggy, and how it was buggy, I apt-get sourced it, fixed
it, and installed it on all my machines. I have now no machines with
that particular bug left. My hunch is that when using network namespaces
with
While I can visually confirm that the fix in comment #10 is now in the
zesty source code (and the fix is not in the xenial/yakkety source
code), I'm unable to actually recreate the experience of a valgrind
failure on xenial (I've attempted with both i386 and amd64 xenial
containers). I
I'll take a look at this one.

By the way, the bug was fixed already:
http://git.kernel.org/cgit/linux/kernel/git/shemminger/iproute2.git/commit/?id=a1b4a274d4917be06b3060d3c8e95aba5c92a9a9
So by upgrading to ip version 4.5 this should be fixed.

Well, either that or you change struct nsid_cache (line 138) to
struct nsid_cache {
struct hlist_node nsid_hash;
struct hlist_node name_hash;
int nsid;
charname[1];
};
I think that that would do the same.

Please reopen as I've found the cause of the bug and posted it to the
forum.

I found the bug: in the package iproute2 version 2-4.3, in the file
ip/ipnetns.c, line 175 must read:
c = malloc(sizeof(*c) + strlen(name) + 1);
instead of:
c = malloc(sizeof(*c) + strlen(name));

I have no idea if or whether the 16.10 and 16.04 versions are somehow
the same. I'll see if I can write a script to reproduce the bug (which I
forgot to post: this causes a segfault).

Hello,
Thank you for filing this bug report! I am unable to reproduce this in
16.10, which has the same version of iproute2 currently
(4.3.0-1ubuntu3). Do you have any local configuration that might be
relevant?
Thanks,
Nish
