OK, then why restrict hardlinks to symlinks -- they can't
be setXID. Same with anything other than a file. They can't be used
in the same way. The restrictions on 'non-files' became worse -- in that
the DACL(incl mode) is ignored.
For files... disallow linking to setXid (or setcap) files, and
for 'icing' disallow hardlinks to/from files in world readable sticky dirs.
Wouldn't those restrictions have given the same benefit...(focusing,
BTW, on the restrictions on hardlinks).

In that case, should 'root's DACL override ability trump the
protections setup by the sticky-bit. If root programs are going
to insist on using the same world-writeable sticky bits as all other
users, it seems only prudent that increased restrictions apply -- not
only to protect root, but other users --- If root can just overwrite
any file -- if that was a tmp file that is being read for final
saving in the user dir of an important file -- wouldn't that be equally
bad?
I.e. maybe root shouldn't be able to open an existing file (not owned
by root) in a sticky-dir -- but would need to move or remove it first.
Wouldn't the above restrictions accomplish the same security goals with
less impact to compatibility w/existing features?

How would that be different than the user creating
a symlink in tmp? I.e. Theoretically, they can already create
a symlink in tmp.

If there's a URL for to explain why this is needed, I'd
love to read more. My background is computer science and have
have worked in security, so I'm aware of theory, but logically,
I am still not seeing the chain of events. It seems like the
protected symlink was designed for use in a world-writeable w/
sticky bit set, so I'm not seeing the need for the extra
check on hard-link in relation to that.
It seems more like use of a blunt instrument rather
than making use of the mode bits (or DACL) on a symlink.
As far as the given reasoning for symlink control,
I've not heard of any issues related to TOU on devices/pipes
or other file system objects that couldn't be applied to files.
I.e. Do you know why they'd blanket ban everything except
files?
BTW -- you said:

The business of using "groups" for access control is being
increasingly ignored in many system utils -- something I find
very annoying. Maybe, with increasing use of user and group
specific ACL's, someone might realize that group access can
also be used selectively. Too many system utils are checking
to see that they are root-user-only writeable which supersedes
a local site's security policy.

I wasn't are of the problem until just recently and I think
the hardlink part of it is 'not well considered' given the current
evidence, but I'd really like to know better what made it a problem.
At least, we are agreed on 'cp' doing the most good for the most users.
That principle seems increasingly lost amongst the legalistically
inclined (c.f. shoveling snow off the sidewalk in front of your house,
where owners were held liable if they had shoveled (i.e. took mitigating

It's not the access rights, but usually a ToCToU and/or race condition problem in /tmp with symlinks. An outstandingly large amount of administrative software is written that dumps things into /tmp with static names. An attack can take advantage of that by dropping a symlink in place in /tmp and the software follows it and does things like overwrites /etc/passwd. So, the symlink restriction logic basically says "owner of symlink must match dir owner or uid of follower". So, allowing a hardlink to a symlink means that symlinks owned by the target user could be hardlinked to in /tmp. The attack gets more and more remote, but these kind of flaws are not unheard of. Regardless, if your system isn't at risk for such attacks, makes sense to turn if off if it's getting in your way. :) -Kees -- Kees Cook Chrome OS Security

So how it use to be, was that I didn't have write access to the files, so I couldn't save edits w/o renaming the original and then saving the edits as a new version. I spent more time tracking down the problem because I got the error this time even with the group perms set... that lead me to the hardlink->symlink practice... So the only reason I had write access was to get around the first bits of this problem -- I wonder if they disallowed any non-regular in a more recent update than when the other stuff went in. Either that or a package update from my vendor added the default-on rule. I spent more time to investigate this time (as I duped 3.13 -> 3.13.7 and applied patches) , because I found that I didn't need to reapply a local patch to the last kernel build w/new sources and that was because my changes now didn't need to be made to a copy, but flowed right into the source tree for any sub-releases dependent on that Maj-Min combo. Oh well. I.e. I relied on the r/o access to keep myself inline... ;^). > Yeah, it'd be nice if the symlink bits had meaning.

A symlink doesn't act like an SUID (or has that changed?) -- if the object the symlink pointed to was write protected against the user, they would still be hard pressed to exploit it. How would having a pointer to the file (that still follows tree traversal rules - i.e - only allowing access to paths the user could gotten to anyway) confer new access rights to a user?

Right, you found the code already, but just to answer it again:
currently the hardlink check rejects anything that isn't a regular
file if owners don't match:
static bool safe_hardlink_source(struct inode *inode)
{
umode_t mode =3D inode->i_mode;
/* Special files should not get pinned to the filesystem. */
if (!S_ISREG(mode))

Yeah, this is a poor interaction. The trouble with hardlinks is that
they retain the original ownership. This is what leads to the
"dangerous" security concerns for hardlinks. But in the symlink case,
thing are weird because they can only be created, not written.

Seems like doing the fallback would serve most users best. Just keep
it documented in the case of really weird stuff like above. Though
this case of hardlink-copying a writable unowned tree is pretty
unusual already! :)

Yeah, it'd be nice if the symlink bits had meaning. However, relaxing
this check on the kernel side results in bad scenarios, especially
when combined with the symlink restrictions. e.g., creating a hardlink
to a symlink that matches the directory owner in /tmp. Now an attacker
controls the destination of a followable symlink. It's just a really
poor interaction between hardlinks, symlinks, and sticky directories.
But if you don't run a system where you have to worry about /tmp races
and such, the protections are much less important.

Regardless of the outcome for "cp", it seems like turning off this
restriction on the system you're doing this on would be the best
short-term solution. It sounds like you're not using a Debian or
Ubuntu system which carries defaults in /etc/sysctl.d/ files. Fedora's
systemd likes to put defaults into /lib/sysctl.d, if that helps you
track it down. I think systemd recognizes /etc/sysctl.d for overriding
settings in /lib/sysctl.d, so you might be able to set it there
instead.

Agreed, but :)
Old systems that didn't support hardlinks to symlinks, would not depend
on that functionality, and thus the workaround of creating new symlinks is OK.
Going forward, all systems will support hardlinks to symlinks
and those systems might rely on that functionality.
Consider:
while sleep 1d; do
find source/ -links 1 | process_new_files_or_links
cp -al source/ snap_$(date +%s)/ || break
done
If cp -al silently created symlinks as a fall back, then the above
would continue to erroneously process existing symlinks.
This could happen if an existing script is copied to a new system
with /proc/sys/fs/protected_hardlinks enabled.
This is my main concern with the fall back. The inconsistency
concern (with not also handling setuid files or fifos etc.) is
valid also, but secondary as it's less likely and shouldn't
cause a logic issue like above.
Maybe the above case is a bit esoteric, but logic wise it's sound.
Also this whole issue is a _little_ unusual anyway because usually
it's the root user doing the cp -al, or the owner of source/
Ideally the solution to this would be to adjust the symlinks in source/
in such a way that one could hardlink them, or otherwise relax this
restriction in the kernel. That would be preferable as it would
be available for all applications rather than placing possibly
problematic workarounds in a single program.

---
It's not second guessing -- it's responding to a lower capability (or less
privileged) environment. It also depends on whether or not those features are
turned on (i.e. by assigning 0/1 to
/proc/sys/fs/paranoid_protected_{hard,soft}links). AFAIK, my vendor may have
them set somewhere in boot code I haven't audited ( -- I've never had a need to
audit my startup code till they started forcing systemd down everyone's throat
and putting dummy wrapper calls in the sysVinit code).
I.e. they've converted it from a system where doing a 'cp -al' worked
reliably to one where it doesn't. If it doesn't work reliably, then it seems
the, *cough*, posix mandate should followed....
But the outcome would be that cp would still just work -- just within the
bounds of what it is allowed to do. Instead the attitude seems to be, gosh
if we can't have it the way it was, we shouldn't try to have it all.
The kernel bug is a separate issue -- since I CAN link to the file (permissions
allow it), but the same permissions on the link are ignored.
Note -- I grant that permissions ANd ownership on symlinks have always
been ignored (at least in experience), but if they are going to start
using permissions to enable/disallow hardlinking, maybe they shouldn't carve
out a special exception for symlinks.
But those are separate for how cp should behave on filesystems with varying,
"assumed" capabilities...(i.e. failing because one can't link to a symlink
when linking to symlinks isn't a requirement for this to be allowed on
systems that don't support symlinking at all). I.e. as it stands, the ability
to hardlink to a file is dependent on what features and policies your
kernel has built in. Cp should work as well as possible regardless of
those policies.
I.e. what is the posix policy for handling linking requests when the OS has
disabled them? If they wanted to disable copying the tree, they would make
it non-readable.

Why couldn't it create a device or other object under the user account? I.e. if I use a fifo in my build process at the top, -- all that I need is for it to exist -- it doesn't need to be and probably shouldn't be a hardlink. cp has a workaround for directories and it has exactly this workaround on other OS that don't support hardlinking. I don't see why this shouldn't be treated similarly to the 2nd case, as the OS no longer supports hardlinking in as many cases as it used to -- so why shouldn't it fall back? If the user is IN a group that is setGID, then it can be recreated under their UID, if it is another USER... again, that might not be what is needed -- maybe it needs to be the user who created the tree. It is possible to work around most of those cases if not all. But most important -- what % usage are those use cases for cp -al? I.e. copying tree's w/devices FIFOS et al that are owned by someone else? The dirs+files (regular) are the normal case, symlinks can be done because it makes sense, the rest, I think should be there as well, but don't care about as much. > So I'm with you; let's leave this one alone. --- core utils are becoming less functional and less core with every new feature.

And it isn't really a problem.
Many times you'll see a link outside the hierarchy to a
directory or such -- even a file -- rather than including
it in dir -- because hardlinks are often not practical.
(cross devs...etc). As for relative links outside the tree
they'd still work too if you are making a copy parallel in
the same tree. I have these little gems in my
linux source/build tree:
lrwxrwxrwx 1 15 Jun 26 2010 clean_tree -> kbin/clean_tree*
lrwxrwxrwx 1 15 Jun 26 2010 doit -> kbin/install_it*
lrwxrwxrwx 1 15 Jun 26 2010 install_it -> kbin/install_it*
lrwxrwxrwx 1 11 Feb 28 2013 kbin -> ../law/kbin/
lrwxrwxrwx 1 8 Mar 26 20:52 linux -> ish-3137/
lrwxrwxrwx 1 16 Jun 26 2010 list_source -> kbin/list_source*

At over 300 to now over 500MB/tree that would be alot of wasted space if
they were not linked, but linked, even diff versions are relatively small:
because of tree linking:

What would a 'sensitive symlink' be?
I.e. AFAIK, any user can create a symlink to any file in
a directory they own. That doesn't give any privilege that
I am aware of -- it's just a "shortcut" to the file.
hardlinks, I could see a that since the user is incrementing
(and changing the link count in the inode), they'll end up
changing the CTIME value -- before, nothing controlled that.

In my case, that's 1) what I thought it was doing, 2) all that is
needed, as I'm using the 2nd area as a build-tree. I wanted
the source files r/o (i.e. I'd prefer I not have write access so I
don't accidently change the sources in the source tree.
But I didn't even think about this problem when I first encountered
it -- I just made sure setGID was set on the dirs and made sure
they were group writeable.
Of course, IMO, I'm less protected than I was before, as before,
I'd have to explicity su/sudo to root to change a root-owned file.
But now.. I can just write to it because I've ensured group has
write.

Well, that's ok ..... I'm not using it to create a mirror.
Just a linked copy that if I want to change a source file, I have
had to move the original out of the way to save any edits. Which now
I don't... wonderful.
But for devices, at least, recreating the same device
by Maj,Min & type would be fine for the purpose you mention.
Not sure how often people use that to mirror.. certainly one wouldn't
normally think to link to a device in /dev:
> ln /dev/zero xxx
ln: failed to create hard link ‘xxx’ => ‘/dev/zero’: Invalid cross-device link
If it is in my own directory, it works, but not sure if I care...
Fifos are a bit different, no? Aren't they uniq /path?
But still, if I was doing a copy of something that was
uniq, I wouldn't expect to be able to do anything other than
make a symlink to it somewhere.
suidfiles... someone might expect that.. but its never been a feature
I've relied on, since almost any change used to turn off the suid feature
and require explicitly resetting it... but it appears that isn't
true now either.

Um... if you are trying to use cp -al source mirror and you
can't copy the symlink (or create a symlink to it), the issue is
moot.
I.e. I think the proposal.. and what I thought cp already, effectively
did, was link to what was linkable and copy the rest.
It doesn't' link to directories either -- which some OS's allow,
does that mean take it out for files? If the OS disallows a 'linkto'
action, then it would be sensible to at least try to make a copy of it
If I really want an exact copy, I'd su to root and probably use
a dump & restore...

What disadvantages? If cp already does this on systems
that don't support hardlinking, that's what we have here. linux
has changed, and no longer allows except under special circumstances.
Given that, as close a copy ("-a" should be made)...
I.e. I want cp to do, *literally* what the manpage says...
create a copy, but link to files (which posix can redefine to include
directories -- but it would change whether or not linux could link
to them). I don't consider the devices/fifos etc. to be files.
They are types of FS objects but a file is something that holds data
(by common understanding, not posix "new speak").
goto google and type in "what is a file"...
It's a resource for storing information... a collection of data or
information...etc. That doesn't really include sockets, fifos, pipes
and devices...
Except for the setuid issue -- but even there -- if the user is in
the affected group, that should be mutated into a copy as well.
Since you mention that making copies is what is already done in
situations where the OS doesn't support it, I can't see why you wouldn't
do that here.

So this is a tricky one.
The specific restrictions with "protected_hardlinks" are at:
http://lxr.linux.no/linux+v3.13.5/fs/namei.c#L751
One can see there that for files you don't own.
you can only hardlink them if they're non setuid regular files,
and if you can read and write them. So that excludes symlinks,
and fifos etc. as we've seen.
I think I see the reason for excluding symlinks here.
It's so one is able to remove a sensitive symlink and know there
are no more links to it that could be later replaced back.
Allowing that could bypass subsequent "protected_symlinks" checks.
Now we could fall back to creating separate symlinks,
like we do on systems that don't support hard links to symlinks.
This could be useful given that these less security
sensitive symlinks might be just as useful to the user.
I've attached a patch for illustration.
However I don't like it because it doesn't deal with,
1. fifos, device files, setuid regular files, nor,
2. relative symlinks that traverse outside the copied hierarchy.
3. Also if you were using `cp -al source mirror`, and subsequently
wanted to use the link count to see what was added in source,
then symlinks having a link count of only 1 would mess that up.
So given this is a system security policy that's restricting the operation,
and falling back to a less security sensitive operation has at least
the above 3 disadvantages, I'm not sure there is anything we should do here.
thanks,
Pádraig.

----
Actually, we've already verified that creating hardlinks to regular
files works because I have write access to the file I am linking to.
I also have write access to the symlink if you look at the mode-bits.
Pádraig Brady also verified this.
There is more than one problem or issue here.
The part that is in coreutils is that if for some reason a symlink
cannot be linked to, then the symlink should be copied (not what
the symlink is pointing to, but the actual contents of the symlink
inode -- i.e. the redirection path). Like directories copied with
cp -al, symlinks would be owned by the user if this situation comes
up -- but they would still be functional.
The kernel part of this are the changes associated with
/proc/sys/fs/protected_{hard,soft}links -- which seem to be on by default
resulting in incompatible behavior. Pádraig referenced a blog
where these new behaviors were justifiable on the theory that
sys admins might be easily tricked into doing random chowns of all
files for users on request without investigating or wondering why...
*ahem*...yah...

It indeed is a kernel thing having to do with security. Not only can 'cp' not create hardlinks to symlinks; it also can't create hardlinks to regular files. The problem affects all applications, e.g., 'ln'. Not much that coreutils can do about it, as far as I can see, as it's a kernel issue. You can work around the problem by running 'cp' (or 'ln' etc.) as root. Here's an example, where I am running as a regular (non-root) user that is not in the 'root' group: $ find dir/a -ls 5300828 0 drwxrwxr-x 2 root root 80 Mar 26 16:50 dir/a 5338695 4 -rw-r--r-- 1 root root 5 Mar 26 16:50 dir/a/data 5300831 0 lrwxrwxrwx 1 root root 9 Mar 26 11:20 dir/a/symfile -> ../b/file $ mkdir d $ ln dir/a/data d ln: failed to create hard link ‘d/data’ => ‘dir/a/data’: Operation not permitted $ ln dir/a/symfile d ln: failed to create hard link ‘d/symfile’ => ‘dir/a/symfile’: Operation not permitted

My guess is that it's SELinux. Try doing the following: 1. Create 'dir' as before. 2. As the user, run the following shell commands: LC_ALL=C export LC_ALL ln dir/a/symfile dir/b Assuming this fails, look at the output of: strace ln dir/a/symfile dir/b My guess is that you'll see something like this: linkat(AT_FDCWD, "dir/a/symfile", AT_FDCWD, "dir/b/symfile", 0) = -1 EPERM (Operation not permitted) If so, the problem would appear to be in SELinux itself.

Still -- that I can link to a file but not a symlink is an obvious flaw in the implementation. I.e. I have write access to the file -- so I should be able to link to it under their new rules, but I also have write access to the symlink as the mode bits are 777. That's a bit bogus. They are creating a special case where there shouldn't be one. I'm the directory owner -- I should be able to create arbitrary 'entries' in the directory as I own the directory's content -- that's been the tradition interpretation. Though the traditional rules never applied to symlinks -- and now they've come up with an incompatible access method for symlinks... If they really wanted to make them non-linkable, they should start recognizing the mode bits on the symlink (to change the content of the symlink -- which, in this case, is where it points).

Per the POSIX definition, symlinks, directories, FIFOS, and all other special files are still "files" - the term "file" includes not only "regular files" but all other named entities in the file system. Directories are the only special file type that cannot generally be hardlinked according to POSIX rules (and even then, POSIX allows the Solaris behavior where the superuser CAN hardlink directories, with the caveat that doing so causes weird behaviors). --=20 Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org --k0kiNv8sF9SsExls5ufs7mI6SsR1gitOp Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBCAAGBQJTM0E0AAoJEKeha0olJ0NqT6QIAJP5HNY+WjwrmvKT3Yhe82zg a2SZUbpytdQIm6dyXI992SueIme1gboPWDfqFbO1MQo1q0v5YpYgcwMMWQpUGS+y 8xtYv0nWPHbVvjxYo1ejtCkB9XvWS/jtJXMfv31TefAa5JCNv5tfDl2F6Z/WO4HL dvTfqr2SG7vjdyefeGGb5V5BwdVsIWYeC4K1nF7gHAXY8jyi/SrUAbwAExf9OnDk MnkVhfh1wU9sIL+o2AGcDTYt3abzDOxzTD4PI2XktH611qZ7HfdRO/NqHMLDayo8 DBREC3rgXbI6AcSpGkHWvYbmaDoCnnqA2EGajySA8StghiLsryuk3yutdkry1kQ= =1xp+ -----END PGP SIGNATURE----- --k0kiNv8sF9SsExls5ufs7mI6SsR1gitOp--

You are implying that I wrote differently than I thought -- an accusation of deliberate lying if one was to look at your response (which I don't think is what you intended -- you were just trying to be abrasive in your answer). You could say what I knew was dated, but simply saying 'wrong' to that sentence shows a lack of understanding of what was said. Nevertheless, it if it can't link to the symlink (like it cannot like to directories), then it should copy the symlink. Whether it is a relative or an absolute symlink, the symlink is readable and can be copied. Furthermore, the man page says "-l: hard link files instead of copying'. AFAIK, symlinks are not files any more than directories (or is that wrong too and they are now considered to be 'files'? FWIW, the behavior does seem to be caused by the new buggy security behavior. I.e. it makes no sense that I can hardlink to a file, but not a symlink in the same directory.

That is true, but I confirmed that this is caused by "protected_hardlinks"
Perhaps there is a blanket ban on symlinks if you're not the owner,
since the symlink could be later changed to point somewhere more sensitive?
Kees do you know if this is the case?
$ ln dir/b/file flink
$ ln dir/a/symfile slink
ln: failed to create hard link ‘slink’ => ‘dir/a/symfile’: Operation not permitted
tp2:lt$ echo 0 | sudo tee /proc/sys/fs/protected_hardlinks
0
$ ln dir/a/symfile slink
$ rm slink
# And to demonstrate that "protected_symlinks" doesn't seem to be significant here:
$ echo 1 | sudo tee /proc/sys/fs/protected_hardlinks
1
$ echo 0 | sudo tee /proc/sys/fs/protected_symlinks
0
$ ln dir/a/symfile slink
ln: failed to create hard link ‘slink’ => ‘dir/a/symfile’: Operation not permitted
So should we fall back to our symlink emulation if we get EPERM from linkat() ?
I'd like to get some more info on this behavior before doing that though.
thanks,
Pádraig.

Wrong. Linux and Solaris have been able to hard link to symlinks for YEARS; and POSIX 2008 standardized that ability when it added the linkat() syscall.

As far as I know, you could never hardlink
to a symlink. only to a file. A symlink is more like
a directory in that regard.
Looking at the article, it doesn't seem it should apply...it
says
1) The solution is to permit symlinks to only be followed when outside a sticky
world-writable directory,
[it isn't in a sticky world writable directory] or when the uid of the
symlink and follower match, or when the directory owner matches the symlink's owner.
[in the created dir, the symlink and directory owner match]
2) The solution is to permit hardlinks to only be created when the user is
already the existing file's owner, or if they already have read/write access to
the existing file.
[ Already have r/w access to the file via being in group root and the group
having write access]
I think I did run into this change, though, and because of it, my system
is less secure. ... I.e. in my use case, am copying a source tree
into a 2nd tree. I am the directory owner of all dirs in the 2nd tree,
but all the source files should allow my linking to it as the permissions
on the inode protect the contents of the inode. The access to create a
hardlink to that inode has always been controlled by the directory owner,
but it never gives them write access to the content.
Their exploit case was for a stupid admin who chowned all files in a user's dir
"for them" -- why would that EVER be done? I.e. the root admin should
be immediately suspicious as to why they'd need that done. Since you
can't hardlink directories, the only way for a foreign owned directory
to get into someone's home space, would be if they opened the permissions
on the parent then later closed them.
The whole premise of their change relies on the user tricking the admin.
But if that's so easy, the user already has root access, effectively,
and the games up.

No, the file it points to, if you look at my example
is rw for the 'group' members.

So I think the change to use hardlinks to symlinks rather than new symlinks happened with:
http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=594292a1
I.E. The "new symlink" behaviour only happened between v8.0 and v8.10 inclusive.
So why is the hardlink to symlink being disallowed?
I wonder is it due to "protected_hardlinks":
http://danwalsh.livejournal.com/64493.html
If we fell back to using symlinks, would that only
push the perm issue on to when the symlink was followed?

have a simple test case:
as root (w /umask 002):
mkdir -p dir/{a,b}
touch dir/b/file
ln -s ../b/file dir/a/symfile
---
So now tree should look like:
> tree -AFugp dir
dir
+-- [drwxrwxr-x root root ] a/
| +-- [lrwxrwxrwx root root ] symfile -> ../b/file
+-- [drwxrwxr-x root root ] b/
+-- [-rw-rw-r-- root root ] file
----
Now, w/normal user, who is in group root, try:
cp -al dir dir2
cp: cannot create hard link =E2=80=98dir2/dir/a/symfile=E2=80=99 to =E2=80=
=98dir/a/symfile=E2=80=99: Operation=20
not permitted
-----
Trying to link to a symlink is the bug --
it used to duplicate the symlink.
This is a recent behavior
change -- i.e. looking at earlier behavior, the symlinks,
like the directories are created as the 'user', and
only files are linked to.
Core utils version: 8.21 (suse rpm coreutils-8.21-7.7.7.x86_64)
Any idea how this managed to be broken?
