D'oh, yes.

Sorry, I'd wanted to ack the fact that there was a real bug before I went to bed.

I'll send a proper patch tonight.

* [PATCH v4] Introduce v3 namespaced file capabilities

  To: Eric W. Biederman; +Cc: Masami Ichikawa, containers, lkp, xiaolong.ye, LKML

Root in a non-initial user ns cannot be trusted to write a traditional
security.capability xattr.  If it were allowed to do so, then any
unprivileged user on the host could map his own uid to root in a private
namespace, write the xattr, and execute the file with privilege on the
host.

However supporting file capabilities in a user namespace is very
desirable.  Not doing so means that any programs designed to run with
limited privilege must continue to support other methods of gaining and
dropping privilege.  For instance a program installer must detect
whether file capabilities can be assigned, and assign them if so but set
setuid-root otherwise.  The program in turn must know how to drop
partial capabilities, and do so only if setuid-root.

This patch introduces v3 of the security.capability xattr.  It builds a
vfs_ns_cap_data struct by appending a uid_t rootid to struct
vfs_cap_data.  This is the absolute uid_t (that is, the uid_t in user
namespace which mounted the filesystem, usually init_user_ns) of the
root id in whose namespaces the file capabilities may take effect.

When a task asks to write a v2 security.capability xattr, if it is
privileged with respect to the userns which mounted the filesystem, then
nothing should change.  Otherwise, the kernel will transparently rewrite
the xattr as a v3 with the appropriate rootid.  This is done during the
execution of setxattr() to catch user-space-initiated capability writes.
Subsequently, any task executing the file which has the noted kuid as
its root uid, or which is in a descendent user_ns of such a user_ns,
will run the file with capabilities.

Similarly when asking to read file capabilities, a v3 capability will
be presented as v2 if it applies to the caller's namespace.

If a task writes a v3 security.capability, then it can provide a uid for
the xattr so long as the uid is valid in its own user namespace, and it
is privileged with CAP_SETFCAP over its namespace.  The kernel will
translate that rootid to an absolute uid, and write that to disk.  After
this, a task in the writer's namespace will not be able to use those
capabilities (unless rootid was 0), but a task in a namespace where the
given uid is root will.

Only a single security.capability xattr may exist at a time for a given
file.  A task may overwrite an existing xattr so long as it is
privileged over the inode.  Note this is a departure from previous
semantics, which required privilege to remove a security.capability
xattr.  This check can be re-added if deemed useful.

This allows a simple setxattr to work, allows tar/untar to work, and
allows us to tar in one namespace and untar in another while preserving
the capability, without risking leaking privilege into a parent
namespace.

Example using tar:

 $ cp /bin/sleep sleepx
 $ mkdir b1 b2
 $ lxc-usernsexec -m b:0:100000:1 -m b:1:$(id -u):1 -- chown 0:0 b1
 $ lxc-usernsexec -m b:0:100001:1 -m b:1:$(id -u):1 -- chown 0:0 b2
 $ lxc-usernsexec -m b:0:100000:1000 -- tar --xattrs-include=security.capability --xattrs -cf b1/sleepx.tar sleepx
 $ lxc-usernsexec -m b:0:100001:1000 -- tar --xattrs-include=security.capability --xattrs -C b2 -xf b1/sleepx.tar
 $ lxc-usernsexec -m b:0:100001:1000 -- getcap b2/sleepx
   b2/sleepx = cap_sys_admin+ep
 # /opt/ltp/testcases/bin/getv3xattr b2/sleepx
   v3 xattr, rootid is 100001

A patch to linux-test-project adding a new set of tests for this
functionality is in the nsfscaps branch at github.com/hallyn/ltp

Changelog:
   Nov 02 2016: fix invalid check at refuse_fcap_overwrite()
   Nov 07 2016: convert rootid from and to fs user_ns
   (From ebiederm: mar 28 2017)
     commoncap.c: fix typos - s/v4/v3
     get_vfs_caps_from_disk: clarify the fs_ns root access check
     nsfscaps: change the code split for cap_inode_setxattr()
   Apr 09 2017:
       don't return v3 cap for caps owned by current root.
      return a v2 cap for a true v2 cap in non-init ns
   Apr 18 2017:
      . Change the flow of fscap writing to support s_user_ns writing.
      . Remove refuse_fcap_overwrite().  The value of the previous
        xattr doesn't matter.
   Apr 24 2017:
      . incorporate Eric's incremental diff
      . move cap_convert_nscap to setxattr and simplify its usage
   May 8, 2017:
      . fix leaking dentry refcount in cap_inode_getsecurity

This looks like a good fix but ouch! That interface is wrong.

The dentry is needed because vfs_getxattr_alloc does:
	error = handler->get(handler, dentry, inode, name, NULL, 0);

Which is has no business taking a dentry as xattrs are inode concepts.

I have no issue with your patch but it looks like that handler issue
is going to need to be fixed with xattrs.

True, it's a bit clunky.

Any reason not to just have the current vfs_getxattr_alloc() become a
lightweight wrapper calling inode_getxattr_alloc(dentry->d_inode)?

My deep issue is that handler is functions like posix_acl_xattr_get.
And all of those functions that vfs_getxattr_alloc calls should not
take a dentry.

So I feel like I have just spotted the tip of an iceberg that needs
sorting out.

Hi Serge,


   I have been looking at patch below primarily to learn how we could 
apply a similar technique to security.ima and security.evm for a 
namespaced IMA. From the paragraphs above I thought that you solved the 
problem of a shared filesystem where one now can write different 
security.capability xattrs by effectively supporting for example 
security.capability[uid=1000] and security.capability[uid=2000] written 
into the filesystem. Each would then become visible as 
security.capability if the userns mapping is set appropriately. However, 
this doesn't seem to be how it is implemented. There seems to be only a 
single such entry with uid appended to it and, if it was a shared 
filesystem, the first one to set this attribute blocks everyone else 
from writing the xattr. Is that how it works? Would that work 
differently with an overlay filesystem ? I think a similar model could 
also work for IMA, but maybe you have some thoughts. The only thing I 
would be concerned about is blocking the parent container's root user 
from setting an xattr.

Regards,
    Stefan

One disadvantage of this approach is that whoever is setting up the
container would need to go touch the security.ima attribute for each
file in the contianer, which would slow down container creation time.
For capabilities this makes sense, because you might want the file to
have different capabilities in different namespaces, but for IMA,
since the file hash will be the same in every namespace, it would be
nice to use a design that avoids touching each file on new ns
creation.

Cheers,

Yes, that's how this works here.  I'd considered allowing multiple
entries, but I didn't feel that was needed for this case.  In a previous
implementation (which is probably in the lkml archives somewhere) I
supported variable length xattr so that multiple containers could
each write a value tagged with their own userns.rootid.  Instead,
in the final version, if root in any parent container writes an
xattr, it will take effect in child user namespaces.  Which is
sensible - the parent presumbly laid out the filesystem to create
the child container.

> that work differently with an overlay filesystem ? I think a similar

Certainly an overlay filesystem should be an easy case as the container
can have its own copy of the inode with its own xattr.  Btrfs/zfs
would be nicer as the whole file wouldn't need to be copied.

So if you have container c1 creating child container c2 on host h1,
then if c1 creates an xattr, can c2 not use that?  And if h1 writes it,
can c1 and c2 use it?

If they can't, then I guess for IMA multiple xattrs would need to be
supported.

Actually IMA in appraisal mode also supports signatures in the extended 
attributes. Depending on which (public) keys you put on the IMA keyring 
for a namespaced IMA, you may need a different signature on a file to be 
able to access it (execute it for example). For this to work containers 
would have to be able to ship with security.ima xattrs embedded in them 
and users should be able to apply signatures on files on a running 
container (or while building it). I worked on a prototype for namespaces 
IMA before where one of the issues was the CAP_SYS_ADMIN gate that 
disallows setting of security.ima when dropped. So some form of 
exception would have to be granted to be allowed to set security.ima 
from inside a container while CAP_SYS_ADMIN isn't there. And of course 
we need to protect the host's filesystem from an attack where the user 
just modifies the security.ima signature associated with a file.

Actually, this isn't necessarily true: IMA may have the hash, you're
right, but I suspect in most container use cases it will have the
signature.  It's definitely a use case that the container will be using
a different keyring from the host, so different signatures are surely
possible for the same underlying image file.

One might imagine doing the above via overlays, because the new
signature should override the old.

In the case of IMA appraisal the extended attribute security.ima would 
be a signature. For c1 and c2 to use that file they would all have to 
have the same key on their (isolated IMA namespace ) keyring. I think 
this type of setup could be arranged.
Following your attack description in the introduction I would say that 
we would want to prevent malicious modification of a security.ima 
extended attribute:

"Root in a non-initial user ns cannot be trusted to write a traditional security.ima xattr. If it were allowed to do so, then any unprivileged user on the host could map his own uid to root in a private namespace, write the signature in the security.ima xattr, and prevent the file from being accessible on the host."

I am not sure about that. I suppose any extended attribute modifications 
would have to be designed for the case where a shared filesystem is used 
that also shares the extended attributes, not assuming an overlay 
filesystem that automatically isolates the extend attributes. With the 
shared filesystem I'd like to prevent any type of setting of extended 
attributes by a child container or more generally anyone mounting it as 
a '2nd consumer', which would make it a shared filesystem. Only the 
process that mounts a filesystem as the '1st consumer' would be able to 
set the extended attributes. I am assuming that using an overlay fs 
would always make you the '1st consumer' -- I would hope that these 
conditions could be detected. And probably the process should also write 
along its host uid as part of writing out the xattr. If all extended 
attributes were to support this model, maybe the 'uid' could be 
associated with the 'name' of the xattr rather than its 'value' (not 
sure whether that's possible).

Yes, good point, thanks. Assuming the container and the host are using
the same keyring, we could design it in such a way that the container
engine doesn't need to touch every file on creation, which would be
very nice.

I don't think this will be the general case. The host may be Ubuntu, the 
guest could be Fedora and you'll have different keys. I don't think you 
would want the container keys on the host keyring.

Yes, we will definitely support shipping images with the security.ima
xattrs set when namespaced support is available in the kernel.

At least initially, I think it would be fine to require
capable(CAP_SYS_ADMIN); right now the container engine is the one
responsible for setting up the container's rootfs (via downloading an
image and extracting it), and these typically run as root.

Eventually it would be great to relax this, because
"unprivileged/rootless" containers are a thing people are interested
in, but as a first cut I'm not sure it's necessary.

Cheers, and thanks for looking at this!

I guess it depends: if your entire infrastructure needs to be signed
by your ops team, it would (presumably) all be the same ops key. If
you're running off the shelf stuff from the distros or from a vendor,
probably not, I agree.

I think this will largely depend on how IMA works with namespaces. In 
the prototype I mention we had each container have its own _ima keyring 
and the public keys were inside the container at the typical location 
(for physical machines) and the mgmt. stack (docker) basically emulating 
what the initramfs scripts are doing, which is loading all keys from 
/etc/keys/ima into that keyring.

Assuming you want to support container specific executables, you would
want them specifically signed by a key not on the system IMA keyring.

Yes, this is a good point.

Interesting idea.  Worth considering.

> However, this doesn't seem to be how it is implemented. There seems

Indeed, when I was considering supporting multiple simulatenous
xattrs, I did it as something like:

struct vfs_ns_cap_data {
	struct {
		__le32 permitted;
		__le32 inheritable;
	} data[VFS_CAP_U32];
	__le32 rootid;
};

struct vfs_ns_cap {
	__le32 magic_etc;
	__le32 n_entries;
	struct ns_cap_data data[0];
}; // followed by n_entries of struct ns_cap_data

You're instead suggesting encoding the rootuid in the name,
which is interesting.

Approximately - indeed there is only a single xattr.  But it can be
overwritten, so long as the writer has CAP_SETFCAP over the user_ns
which mounted the filesystem.

Hang on.  I've mis-spoken.  That's the requirement for writing a
v2 xattr.  To write a v3 xattr you only need to be privileged
(with CAP_SETFCAP) against the inode.

Ok.  If it's too much of a restriction then certainly we can make
it more flexible.  I don't think we want to support too many versions
of magic in this code, so if there's a chance we'll want to make it
more flexible later, then perhaps we should discuss the other options
in more detail now.

If it were allowed to do so, then any unprivileged user on the host could map his own uid to root in a private namespace, write the signature in the security.ima xattr, and prevent the file from being accessible on the host."

Of course.

The way this is handled with nsfscaps is not by just forbidding the
write, but by only respecting the xattr if the rootid which was
written in the xattr (which is translated and enforced by the kernel
at write time) is root in the caller's user_ns or a parent thereof.

I think that would suffice for ima as well?

Right, again that's currently the case in the nscaps patch.

I think that's what the rootid in the nscaps xattr is.

Right, I missed that in your original email when I saw it this morning.
It's not what my patch does, but it's an interesting idea.  Do you have
a patch to that effect?  We might even be able to generalize that to
namespace any security.* xattrs.  Wouldn't be automatically enabled
for anything but ima and capabilities, but we could make the infrastructure
generic and re-usable.

No, I don't have a patch. It may not be possible to implement it. The 
xattr_handler's  take the name of the xattr as input to get(). So one 
could try to encode the mapped uid in the name. However, that could lead 
to problems with stale xattrs in a shared filesystem over time unless 
one could limit the number of xattrs with the same prefix, e.g., 
security.capability*. So I doubt that it would work. Otherwise it would 
be good if the value was wrapped in a data structure use by all xattrs, 
but that doesn't seem to be the case, either. So I guess we have to go 
into each type of value structure and add a uid field there.

That may be ok though.  Assume the host created a container with
100000 as the uid for root, which created a container with 130000 as
uid for root.  If root in the nested container tries to read the
xattr, the kernel can check for security.foo[130000] first, then
security.foo[100000], then security.foo.  Or, it can do a listxattr
and look for those.  Am I overlooking one?

Hm.  Yeah.  But really how many setups are there like that?  I.e. if
you launch a regular docker or lxd container, the image doesn't do a
bind mount of a shared image, it layers something above it or does a
copy.  What setups do you know of where multiple containers in different
user namespaces mount the same filesystem shared and writeable?

Iiuc, this should also be something that will be addressed by a viable shifts
solution so it's probably not worth worrying about it here. I was going to
point out that there are plans of sharing filesystems between containers
in different user namespaces. However, without shifts this really will only
work nicely if the container's setup identical id mappings in which case you
won't have to worry about stale xattrs.

So that sounds like a child would 'inherit' the value of an xattr from 
the closest parent if it doesn't have one itself. I guess it would 
depend on the xattr whether that should apply? And removing an xattr 
becomes difficult then if the parent container's xattr always shines 
through...

So you think it's a good idea? I am not sure when I would get to it, 
though...

I think I have something now that accomodates userns access to 
security.capability:

https://github.com/stefanberger/linux/commits/xattr_for_userns

Encoding of uid is in the attribute name now as follows: 
security.foo@uid=<uid>

1) The 'plain' security.capability is only r/w accessible from the host 
(init_user_ns).
2) When userns reads/writes 'security.capability' it will read/write 
security.capability@uid=<uid> instead, with uid being the uid of root , 
e.g. 1000.
3) When listing xattrs for userns the host's security.capability is 
filtered out to avoid read failures iof 'security.capability' if 
security.capability@uid=<uid> is read but not there. (see 1) and 2))
4) security.capability* may all be read from anywhere
5) security.capability@uid=<uid> may be read or written directly from a 
userns if <uid> matches the uid of root (current_uid())
6) security.capability@* are 'reserved' and may be read but not written 
to unless 5) applies.


Similat, from the text of one of the functions in the code:

+ * In a user namespace we prevent read/write accesses to the _host's_
+ * security.foo to protect these extended attributes.
+ *
+ * Reading: Reading security.foo from a user namespace will read
+ * security.foo@uid=<uid> instead. Reading security.foo@uid=<uid> directly
+ * also works. In general, all security.foo*, except for security.foo 
of the
+ * host, can be read from a user namespace.
+ *
+ * Writing: Writing security.foo from a user namespace will write
+ * security.foo@uid=<uid> instead. Writing security.foo@uid=<uid> directly
+ * also work.s No other security.foo* attributes, including the 
security.foo
+ * offthe host, can be written to. All security.foo@* are 'reserved'.
+ *
+ * Removing: The same rules for writing apply to removing of extended
+ * attributes from a user namespace.

This looks very close to what we want.  One exception - we do want
to support root in a user namespace being able to write
security.capability@uid=<x> where <x> is a valid uid mapped in its
namespace.  In that case the name should be rewritten to be
security.capability@uid=<y> where y is the unmapped kuid.val.

Eric,

so far my patch hasn't yet hit Linus' tree.  Given that, would you
mind taking a look and seeing what you think of this approach?  If
we may decide to go this route, we probably should stop my patch
from hitting Linus' tree before we have to continue supporting it.

Stefan,

so do you think the general framework could be re-used by IMA?  If
we can move the capability-specific code in fs/xattr.c into
an LSM hook in a way that IMA can also use, then this is a definite
win.

I'll try to write a patch on top of the existing one.

Can  you adapt your test cases. I haven't tried them, but having them 
would be important.

I am fairly sure that this would be easily possible and some of the if 
statements with string comparisons would likely only have to be extended 
with another comparison.

Did that now in a 2nd patch (that also fixes a few problems of the 1st). 
In a user ns mapped to 1000 root can write security.capability@uid=123, 
which then ends up writing to security.capability@uid=1123. The reading 
also works with @uid=123. When listing xattrs only those get shown that 
actually have valid mappings.

Agreed.  I will take a look.  I also want to see how all of this works
in the context of stackable filesystems.  As that is the one case that
looked like it could be a problem case in your current patchset.

Apropos stackable filesystems [cc some overlayfs folks], is there any
way that parts of this work could be generalized towards ns aware
trusted@uid.* xattr?

With overlayfs, files are written to underlying fs with mounter's
credentials. How this affects v3 security capabilities and how exactly
security xattrs are handled in overtlayfs I'm not sure. Vivek?

But, if we had an infrastructure to store trusted@<rootid> xattr, then
unprivileged overlayfs mount would become a very reachable goal.
Much closer goal then loop mounting...

branch nsfscaps of github.com/hallyn/ltp now has a patch on top
which makes it work with your capabilities.  Tests are passing.

I am at least removing all string comparison with xattr names from the 
core code and move the enabled xattr names into a list. For the 
security.* extended attribute names we would enumerated the enabled ones 
in that list, only security.capability for now. I am not sure how the 
trusted.* space works.

I extended 'the infrastructure' now to support prefix matching for 
trusted.* and probably others as well. It's fairly easy to do that but 
would not write the code like that for exact string matching to support 
security.capability. The patch lets me write trusted.foo@uid=100 from 
within the userns if uid=100 exists, rejects it otherwise. It may be 
written out as trusted.foo@uid=1100 for root mapping to uid 1000. I can 
list this entry on the host. For some reason trusted.* is not listed at 
all inside the userns. So something else needs to be enabled as well. 
For now it looks like this:

That looks useful!
I hope someone who knows his way around trusted xattr can say what's missing.

Thanks,

We do switch to mounter's credential for privileged operations but
for a newly created file final selinux label is created as if task
created that file.

>How this affects v3 security capabilities and how exactly
> security xattrs are handled in overtlayfs I'm not sure. Vivek?

Given we switch to mounter's creds for operations on underlying
filesystem (setxattr, getxattr), I thought that it probably
will call xattr_userns_name() in nested manner. Once using tasks's
creds and second time using mounter's creds. So that probably
should have made it security.foo@uid@uid. I tried patches quickly
but setcap/getcap inside containers work. So may be it is
due to the fact that mounting was done from init_user_ns and
following line of code will avoid adding @uid in that case.

+       /* no name changes for init_user_ns or uid == 0 */
+       if (current_user_ns() == &init_user_ns || uid.val == 0)
+               goto out_copy;
+

I have not looked deeper. Still curious how getxattr() path works
when we switch to mounter's creds. In that case underlying file
system will get the impression that mounter task is trying to
do getxattr() in security.capability set by container task. I
am assuming we allow that?

I need to spend more time understanding this.
