[PATCH] uapi: use wildcards to list files

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under include/uapi/ should be exported, so let's
use wildcards.

After this patch, the following files, which were not exported, are now
exported:
drm/vgem_drm.h
drm/armada_drm.h
drm/omap_drm.h
drm/etnaviv_drm.h
rdma/qedr-abi.h
linux/bcache.h
linux/kfd_ioctl.h
linux/cryptouser.h
linux/kcm.h
linux/kcov.h
linux/seg6_iptunnel.h
linux/stm.h
linux/seg6.h
linux/auto_dev-ioctl.h
linux/userio.h
linux/pr.h
linux/wil6210_uapi.h
linux/nilfs2_ondisk.h
linux/hash_info.h
linux/seg6_genl.h
linux/seg6_hmac.h
linux/batman_adv.h
linux/nsfs.h
linux/qrtr.h
linux/btrfs_tree.h
linux/coresight-stm.h
linux/dma-buf.h
linux/module.h
linux/lightnvm.h
linux/nilfs2_api.h

This patch is built against linus tree. I don't know if it should be
done against antoher tree.

Comments are welcomed,
Nicolas

I think the idea makes a lot of sense: if a header is in uapi, we should
really export it. However, using a wildcard expression seems a bit
backwards here, I think we should make this implicit and not have the
Kbuild file at all.

The "header-y" syntax was originally added back when the uapi headers
were mixed with the internal headers in the same directory. After
David Howells introduced the separate directory for uapi, it has
become a bit redundant.

Can you try to modify scripts/Makefile.headersinst instead so we
can simply remove the Kbuild files entirely?

Ok, thank you for the explanation, I was wondering why those Kbuild files were
needed.

I will try something.

This header file is exported, thus move it to uapi.

2.8.1

[Nicolas Dichtel]

Here is the v2 of this series. The first 5 patches are just cleanup: some
exported headers were still under a non-uapi directory.
The patch 6 was spotted by code review: there is no in-tree user of this
functionality.
The last patch remove the use of header-y. Now all files under an uapi
directory are exported.

asm is a bit special, most of architectures export asm/<arch>/include/uapi/asm
only, but there is two exceptions:
- cris which exports arch/cris/include/uapi/arch-v[10|32];
- tile which exports arch/tile/include/uapi/arch.
Because I don't know if the output of 'make headers_install_all' can be changed,
I introduce subdir-y in Kbuild file. The headers_install_all target copies all
asm/<arch>/include/uapi/asm to usr/include/asm-<arch> but
arch/cris/include/uapi/arch-v[10|32] and arch/tile/include/uapi/arch are not
prefixed (they are put asis in usr/include/). If it's acceptable to modify the
output of 'make headers_install_all' to export asm headers in
usr/include/asm-<arch>/asm, then I could remove this new subdir-y and exports
everything under arch/<arch>/include/uapi/.

Note also that exported files for asm are a mix of files listed by:
- include/uapi/asm-generic/Kbuild.asm;
- arch/x86/include/uapi/asm/Kbuild;
- arch/x86/include/asm/Kbuild.
This complicates a lot the processing (arch/x86/include/asm/Kbuild is also
used by scripts/Makefile.asm-generic).

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. I don't know if it should be

made against antoher tree.

Comments are welcomed,
Nicolas

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that unput-files3-name is genhdr-y.

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now

exported (with make headers_install_all):
asm-unicore32/shmparam.h

It should rather not be exported - please remove it from
arch/x86/include/uapi/asm/Kbuild instead.

Just hint for the future:
-M (move)

-D (delete) [though this is NOT for applying]

Since this is meant as a cleanup, I commented on this to point out a cleaner
way to do the same.

Very nice!

This is interesting, though not your problem. Maybe someone who understands
cris better can comment on this: How is the decision made about which of
the arch/user.h headers gets used? I couldn't find that in the sources,
but it appears to be based on kernel compile-time settings, which is
wrong for user space header files that should be independent of the kernel
config.

I don't know if anyone still uses "make headers_install_all", I suspect
distros these days all use "make headers_install", so it probably
doesn't matter much.

In case of cris, it should be easy enough to move all the contents of the
uapi/arch-*/*.h headers into the respective uapi/asm/*.h headers, they
only seem to be referenced from there.

For tile, I suspect that would not work as the arch/*.h headers are
apparently defined as interfaces for both user space and kernel.

The series should probably get merged through the kbuild tree, but testing
it on mainline is fine here.

Moving the file is correct as far as I can tell, but the extra
#include is not necessary here, as the kernel will automatically
search both arch/arm/include/ and arch/arm/include/uapi/.

The same applies to patches 2 and 4.

This one is only a redirect to an asm-generic header, so it can be
removed completely and replaced with a line in the
arch/nios2/include/uapi/asm/ file:

generic-y += setup.h

I believe it's since the CRISv10 and CRISv32 are very different beasts,
and that is selected via kernel config...

This part of the CRIS port has been transformed a couple of times from
the original layout without uapi, and there's still some legacy silliness,
where some files might have been exported but never used from userspace
except for some corner cases.

That still does not mean they should be exported.

Anything but headers (and directories as a skeleton structure) is maximally suspicious.

[Nicolas Dichtel]

What I was trying to say is that I export those directories like other are.
Removing those files is not related to that series.

Perhaps the correct solution is to only copy files matching "*.h" to
reduce the risk of copying files incidentally created by kbuild but
which shouldn't be installed as uapi headers.

[Nicolas Dichtel]

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):

asm-unicore32/shmparam.h

[Nicolas Dichtel]

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
- arch-v[10|32] for cris;
- arch for tile.

[Nicolas Dichtel]

Here is the v3 of this series. The first 5 patches are just cleanup: some
exported headers were still under a non-uapi directory or (x86 case) were
wrongly exported.

The patch 6 was spotted by code review: there is no in-tree user of this
functionality.

Patches 7 and 8 remove the need to list explicitly headers. Now all files

under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. If I must rebase it against the kbuild
tree, just tell me ;-)

v2 -> v3:
- patch #1: remove arch/arm/include/asm/types.h
- patch #2: remove arch/h8300/include/asm/bitsperlong.h
- patch #3: remove arch/nios2/include/uapi/asm/setup.h
- patch #4: don't export msr-index.h
- patch #5: fix a typo: s/unput-files3-name/input-files3-name
- patch #6: no change
- patch #7: fix include/uapi/asm-generic/Kbuild.asm by introducing mandatory-y
- add patch #8

v1 -> v2:
- add patch #1 to #6
- patch #7: remove use of header-y

Comments are welcomed,

These weren't defined by the kernel before, so why do we need to define them
now?

Will defining __UINTPTR_TYPE__ cause problems in compiling libboost by
changing the signature on C++ functions that use uintptr_t?

I see it on my desktop as /usr/include/asm/msr-index.h and it's been there at
least four years - and as such it's part of the UAPI. I don't think you can
remove it unless you can guarantee there are no userspace users.

It is listed in include/uapi/asm-generic/Kbuild.asm, which is included by
arch/arm/include/uapi/asm/Kbuild.

You can also have a look at patch #5 to see why it was exported even if it was
not in an uapi directory.

[Nicolas Dichtel]

I keep it in the v2 of the series, but the maintainer, Borislav Petkov, asks me
to un-export it.

I will follow the maintainer decision.

I mentioned it to David, and he says it's because the long list of
recipients is breaking his mailer. I've already posed the question
about whether that's exploitable!

We really should not be installing non-uapi header files to userland
under _any_ circumstance - this to me sounds like a bug in kbuild.

The assumption is that headers outside of uapi directories are not
part of the user visible API, and so can be freely modified - which
in the presence of this bug is untrue.

However, as it's happening, and this header has been there since 2013
(commit 09096f6a0ee2 - "ARM: 7822/1: add workaround for ambiguous C99
stdint.h types") it's now well and truely part of the user API whether
we intended it to be or not, so your patch looks to me like the correct
thing to do.

I think it needs further evaluation to make sure kbuild isn't going to
do something else silly, like subsitute include/asm-generic/types.h for
the now missing arch/arm/include/asm/types.h

I wonder how many more headers are unintentionally exported.

... what a mess. :(

It's not (or was not) a bug exactly - it was something introduced in commit
10b63956fce7f369cc37fd4d994f09bd5203efe4 to ease the transition to using the
UAPI headers as Linus required the commit for each header dir to go through
the submaintainer's tree.

It was supposed to be removed, but that never got posted to Linus because t=
he
next phase of cleanups didn't happen as Linus said he block my email and ne=

take any more patches from me if I sent him any more:-/

I'm not the maintainer. I simply think that exporting that file was
wrong because it if we change something in it, we will break userspace.
And that should not happen - if userspace needs MSRs, it should do its

I'm taking this patch, but with the following commit log:

Due to the way kbuild works, this header was unintentionally exported
back in 2013 when it was created, despite it not being in a uapi/
directory. This is very non-intuitive behaviour by Kbuild.

However, we've had this include exported to userland for almost four
years, and searching google for "ARM types.h __UINTPTR_TYPE__" gives
no hint that anyone has complained about it. So, let's make it
officially exported in this state.

If anyone has any objections, they better shout sooner rather than
later.

After sleeping on this, here are my thoughts:

First, there are three ways to think about this, not just two. It
could be a BPF feature, a net feature, or a cgroup feature.

I think that calling it a BPF feature is a cop-out. BPF is an
assembly language and a mechanism for importing little programs into
the kernel. BPF maps are a BPF feature. These new hooks are a
feature that actively changes the behavior of other parts of the
kernel. I don't see how calling this new feature a "BPF" feature
excuses it from playing by the expected rules of the subsystems it
affects or from generally working well with the rest of the kernel.

Perhaps this is a net feature, though, not a cgroup feature. This
would IMO make a certain amount of sense. Iptables cgroup matches,
for example, logically are an iptables (i.e., net) feature. The
problem here is that network configuration (and this explicitly
includes iptables) is done on a per-netns level, whereas these new
hooks entirely ignore network namespaces. I've pointed out that
trying to enable them in a namespaced world is problematic (e.g.
switching to ns_capable() will cause serious problems), and Alexei
seems to think that this will never happen. So I don't think we can
really call this a net feature that works the way that other net
features work.

(Suppose that this actually tried to be netns-enabled. Then you'd
have to map from (netns, cgroup) -> hook, and this would probably be
slow and messy.)

So I think that leaves it being a cgroup feature. And it definitely
does *not* play by the rules of cgroups right now.

To me, this sounds like "the API isn't that great, we know how to do
better, but we really really want this feature ASAP so we want to ship
it with a sub-par API." I think that's a bad idea.

Unless I'm mistaken, "perf_event" is an actual cgroup controller, and
it explicitly respects the cgroup hierarchy. It shows up in
/proc/cgroups, and I had no problem mounting a cgroupfs instance with
perf_event enabled. So I'm not sure what you mean.

I'm not sure how important netns support for these bpf programs
actually is but I have no objection to making it behave in an
equivalent manner to iptables where appropriate. This is kinda
trivial to do too. For now, we can simply not run the programs if the
associated socket belongs to non-root netns. Later, if necessary, we
can add per-ns bpf programs. And I can't think of a reason why
(netns, cgroup) -> function mapping would be slow and messy. Why
would that be?

Because this in no way is a cgroup feature. As you wrote above, it is
something similar to iptables with lacking netns considerations.
Let's address that and make it a proper network thing.

I see your point but this isn't something which is black and white.
There are arguments for both directions. I'm leaning the other
direction because

* My impression with bpf is that while delegation is something
theoretically possible it is not something which is gonna take place
in any immediate time frame. If I'm wrong on this, please feel free
to correct me.

* There are a lot of use cases which can immediately take advantage of
cgroup-aware bpf programs operating as proposed. The model is
semantically equivalent to iptables (let's address the netns part if
that's an issue) which net people are familiar with.

* It isn't exclusive with adding cgroup bpf controller down the road
if necessary and practical. Sure, this isn't the perfect situation
but it seems like an acceptable trade-off to me. What ever is
perfect?

Yeah, it is implemented as a controller but in essence what it does is
just tagging the hierarchy to tell perf to use that hierarchy for
membership test purposes.

That all it's doing is providing membership information.

To map cgroup -> hook, a simple array in each cgroup structure works.
To map (cgroup, netns) -> hook function, the natural approach would be
to have some kind of hash, and that would be slower. This code is
intended to be *fast*.

I suppose you could have each cgroup structure contain an array where
each element is (netns, hook function) and just skip the ones that are
the wrong netns. Perhaps it would be rare to have many of those.

I think it's currently a broken cgroup feature. I think it could be
made into a properly working cgroup feature (which I favor) or a
properly working net feature. Can you articulate why you prefer
having it be a net feature instead of a cgroup feature? I tend to
favor making it be a working cgroup feature (by giving it a file or
files in cgroupfs and maybe even a controller) because the result
would have very obvious semantics.

But maybe this is just a false dichotomy. Could this feature be a
per-netns configuration where you can give instructions like "run this
hook if you're in such-and-such netns and in a given cgroup or one of
its descendents"? This would prevent it from being a direct analogue
to systemd's RestrictAddressFamilies= option, but that may be okay.
This would side-step issues in the current code where a hook can't
rely on ifindex meaning what the hook thinks it means.

Actually, I think I like that approach. What if it we had a "socket"
controller and files like "socket.create_socket", "socket.ingress" and
"socket.egress"? You could use the bpf() syscall to install a bpf
filter into "socket.egress" and that filter would filter egress for
the target cgroup and its descendents on the current netns. As a
first pass, the netns issue could be sidestepped by making it only
work in the root netns (i.e. the bpf() call would fail if you're not
in the root netns and the hooks wouldn't run if you're not in the root
netns.) It *might* even be possible to retrofit in the socket
controller by saying that the default hierarchy is used if the socket
controller isn't mounted.

What *isn't* possible to cleanly fix after the fact is the current
semantics that cgroup hooks override the hooks in their ancestors.
IMO that is simply broken. The example you gave (perf_event) is very
careful not to have this problem.

But the issue isn't *BPF* delegation. It's cgroup delegation or netns
creation, both of which exist today.

That sounds like a great argument for those users to patch their
kernels to gain experience with this feature.

I think it more or less is exclusive. I can imagine davem accepting a
patch to make the sock_cgroup_data think point at a new "socket"
cgroup type. I can't imagine him accepting a patch to have sockets
have more than one pointer to a cgroup, with good reason.

I don't see what's added by having a "bpf" cgroup controller, though
-- it's just too broad. If the Landlock stuff goes in, that should
presumably be either tied to the default hierarchy or use an "lsm"
controller. A "bpf" controller for that makes no sense to me.

I can see *huge* value in having some combination of BPF and the
perf_event controller deciding whether to log perf events, for
example. But this would be the perf_event controller, not a
hypothetical "bpf" controller.

It's also a rather innocuous controller in that it doesn't change the
behavior of the controlled tasks. The bpf hooks definitely do change
behavior.

But it's doing it wrong! Even perf_event tests for membership in a
given cgroup *or one of its descendents*. This code does not.

I think the moral of the story here is that there are lots of open
questions and design work to be done and that this feature really
isn't ready to be stable. For Landlock, I believe that it really
needs to be done right and I will put my foot down and NAK any effort
to have Landlock available in a released kernel without resolving
these types of issues first. Does anyone really want Landlock to work
differently than the net hooks simply because the net hooks were in a
rush?

Updating these programs isn't a frequent operation. We can easily
calculate a perfect (or acceptable) hash per-cgroup and rcu swap the
new hashtable.

Yeah, or maybe even that. It just isn't a fundamentally difficult
problem.

How is this different from making the current code netns aware?

I don't know. You're throwing out too many ideas too fast and it's
difficult to keep up with what the differences are between those
ideas. But if we're doing cgroup controllers, shouldn't cgroup ns
support be sufficient? We can consider the product of cgroup and net
namespaces but that doesn't seem necessary given that people usually
set up these namespaces in conjunction.

That's like saying installing an iptables rule for a more specific
target is broken. As a cgroup controller, it is not an acceptable
behavior given how delegation works. As something similar to
iptables, it is completely fine.

No, the issue is bpf delegation. If bpf were fully delegatable in
practical sense, we could just do straight forward cgroup bpf
controller. Well, we'll have to think about how to chain the programs
which would differ on program type but that shouldn't be too hard.

I don't get why this would particularly point to out-of-tree usage.
Why is that?

Why would it ever need multiple pointers? Socket is associated with
one cgroup whether it's this or controller thing. Membership part
doesn't change. It can share everything.

Let's not spiral out. This isn't relevant to the discussion. Call it

No idea about landlock but as for the cgroup aware network bpf
programs, let's please try to narrow down the arguments. Here's one
question.

* If we make the current thing netns aware, how is it different from
iptables? Note that at least future-proofing for netns is trivial.
We can simply skip running the bpf programs for non-root ns for now.

If the answer is "they aren't that different", is the reason that
you're against the current code because you think that it being a part
of cgroup would be more useful? I'm not necessarily against that
point, I just think that this is a reasonable trade-off given the
circumstances especially given that this doens't block having the
cgroup things in the future.

I'd really appreciate some inputs from bpf folks. I'm basing my
judgement primarily on the impression that it is very difficult to
make bpf programs practically delegatable. If that's not the case, we
can easily go the cgroup controller route.

Thanks.

About Landlock, there is two use cases:

The first is to allow unprivileged users to tie eBPF programs (rules) to
processes. This is the (final) goal. In this case, a (cgroup) hierarchy
is mandatory, otherwise it would be trivial to defeat any access rule.
This is the same issue with namespaces.

The second use case is to only allow privileged users to tie eBPF
programs to processes. As discussed, this will be the next series,
preceding the unprivileged series. In this privilege case, only root
(global CAP_SYS_ADMIN, no namespaces) may be able to use Landlock. Not
having a hierarchy is not a security issue (only a practical one).

The first/next Landlock series (in February) will focus on process
hierarchies (without cgroup), a la seccomp-bpf. It would be too
confusing to not use an inheritable hierarchy like seccomp does, even in
a privileged-only first approach. The inherited rules should then behave
similarly to the seccomp-bpf filters.

However, the following series focusing on cgroup could keep the current
cgroup-bpf behavior, without hierarchy. I don't like the non-hierarchy
approach very much because it add another (less flexible and more
confusing) way to do things (for Landlock at least), but I'm willing to
do it if needed.

I thought you were saying why you thought it wasn't a cgroup feature,
but I'm not sure I understand why you thought it shouldn't be a cgroup
feature.

When I chatted with Alexei, I had the impression that you and he had
wanted it to be a cgroup controller but thought it wouldn't work well.
I think it could work by making a single socket cgroup controller that
handles all cgroup things that are bound to a socket. Using
individual files would play nicer with cgroup delegation within a
single netns.

Even the xt_cgroup code checks cgroup_is_descendent().

What do you mean by "if bpf were fully delegatable"? I don't know
what it would even mean to delegate bpf. I do know what it means to
allow programs to create new network namespaces and for cgroup
sub-hierarchies to be delegated.

Because I think that the API currently has some issues that will be
difficult to fix without either breaking the API or supporting
multiple APIs going forward.

Exactly. If it starts out using the default hierarchy and then
switches to being a socket controller, there will still be old
deployed code that tries to attach bpf programs to the default
hierarchy. That will require defining some semantics for it.

Having thought about this some more, I think that making it would
alleviate a bunch of my concerns, as it would make the semantics if
the capable() check were relaxed to ns_capable() be sane. Here's what
I currently should happen before bpf+cgroup is enabled in a release:

1. Make it netns-aware. This could be as simple as making it only
work in the root netns because then real netns awareness can be added
later without breaking anything. The current situation is bad in that
network namespaces are just ignored and it's plausible that people
will start writing user code that depends on having network namespaces
be ignored.

2. Make it inherit properly. Inner cgroups should not override outer
hooks. As in (1), this could be simplified by preventing the same
hook from being configured in both an ancestor and a descendent
cgroup. Then inheritance could be added for real later on.

3. Give cgroup delegation support some serious thought. In
particular, if delegation would be straightforward but the current API
wouldn't work well with delegation, then at least consider whether the
API should change before it becomes stable so that two APIs don't need
to be supported going forward.

From the bpf side, I think that the only thing needed to get
delegation working is to make inheritance work right -- if the same
hook is set up multiple places in the hierarchy, call all of the in an
appropriate order. The rest is probably all on the cgroup side --
setting up a way to enable delegation (subtree_control?), making sure
that filesystem permissions are checked when configuring hooks, and
perhaps dealing with setuid issues.

Such 'socket cgroup controller' would limit usability of the feature
to sockets and force all other use cases like landlock to invent
their own wheel, which is undesirable. Everyone will be
inventing new 'foo cgroup controller', while all of them
are really bpf features. They are different bpf program
types that attach to different hooks and use cgroup for scoping.

here we're on the same page. For any meaningful discussion about
'bpf cgroup controller' to happen bpf itself needs to become
delegatable in cgroup sense. In other words BPF_PROG_TYPE_CGROUP*
program types need to become available for unprivileged users.
The only unprivileged prog type today is BPF_PROG_TYPE_SOCKET_FILTER.
To make it secure we severely limited its functionality.
All bpf advances since then (like new map types and verifier extensions)
were done for root only. If early on the priv vs unpriv bpf features
were 80/20. Now it's close to 95/5. No work has been done to
make socket filter type more powerful. It still has to use
slow-ish ld_abs skb access while tc/xdp have direct packet access.
Things like register value tracking is root only as well and so on
and so forth.
We cannot just flip the switch and allow type_cgroup* to unpriv
and I don't see any volunteers willing to do this work.
Until that happens there is no point coming up with designs
for 'cgroup bpf controller'... whatever that means.

nothing in bpf today is netns-aware and frankly I don't see
how cgroup+bpf has anything to do with netns.
For regular sockets+bpf we don't check netns.
When tcpdump opens raw socket and attaches bpf there are no netns
checks, since socket itself gives a scope for the program to run.
Same thing applies to cgroup+bpf. cgroup gives a scope for the program.
But, say, we indeed add 'if !root ns' check to BPF_CGROUP_INET_*
hooks. Then if the hooks are used for security, the process
only needs to do setns() to escape security sandbox. Obviously
broken semantics.

In general it sounds fine, but it seems the reasoning to add
such restriction now (instead of later), so that program chain can
be added without breaking abi, since if we don't restrict it now
there will be no way to add it without breaking abi?!
That is incorrect assumption. We can add chaining and can add
'do not override' logic without breaking existing semantics.
For example, we can add 'priority' field to
struct { /* anonymous struct used by BPF_PROG_ATTACH/DETACH commands */}
which would indicate relative position of multiple chained programs
applied to the same cgroup+hook pair. Multiple programs with
the same priority will be executed in the order they were added.
Programs with different priorities will execute in the priority order.
Such scheme will be more generic and flexible than earlier proposals.
Similarly we can add another flag that will say 'dissallow override
of bpf program in descendent cgroup'. It's all trivial to do,
since bpf syscall was designed for extensibility.

Also until bpf_type_cgroup* becomes unprivileged there is no reason
to add this 'priority/prog chaining' feature, since if it's
used for security the root can always override it no matter cgroup
hierarchy.

please see example above. Since we went with bpf syscall (instead of
inextensible ioctl) we can add any new cgroup+bpf logic without
breaking current abi.
No matter how you twist it the cgroup+bpf is bpf specific feature.

Can you elaborate on why that would be a problem? In a cgroup v1
world, users who want different hierarchies for different types of
control could easily want one hierarchy for socket hooks and a
different hierarchy for lsm hooks. In a cgroup v2 delegation world, I
could easily imagine the decision to delegate socket hooks being
different from the decision to delegate lsm hooks. Almost all of the
code would be shared between different bpf-using cgroup controllers.

Sure there is. If delegation can be turned on without changing the
API, then the result will be easier to work with and have fewer
compatibility issues.

Here I completely disagree with you. tcpdump sees packets in its
network namespace. Regular sockets apply bpf filters to the packets
seen by that socket, and the socket itself is scoped to a netns.

Meanwhile, cgroup+bpf actually appears to be buggy in this regard even
regardless of what semantics you think are better. sk_bound_dev_if is
exposed as a u32 value, but sk_bound_dev_if only has meaning within a
given netns. The "ip vrf" stuff will straight-up malfunction if a
process affected by its hook runs in a different netns from the netns
that "ip vrf" was run in.

IOW, the current code is buggy.

This could go both ways. If the goal is to filter packets, then it's
not really important to have the filter keep working if the sandboxed
task unshares netns -- in the new netns, there isn't any access to the
network at all. If the goal is to reduce attack surface by
restricting the types of sockets that can be created, then you do want
the filter to work across namespaces, but seccomp can do that too and
the current code doesn't handle netns correctly.

Adding it the straightforward way (by simply making all the hooks in
scope run) would break ABI. Of course there are more complicated ways
to do it, but those are more complicated and messier. Do actually
have a use case in which overriding of hooks is a good thing? As far
as I can tell, the original version of the patch set didn't have hooks
get overridden by descendents, and I don't know why this changed in
the first place.

But then you end up with two ABIs. Ideally delegation would just work
-- then programs written now could run unmodified in unprivileged
containers in future kernels.

... and open() of the directory done by the current api will preserve
cgroup delegation when and only when bpf_prog_type_cgroup_*
becomes unprivileged.
I'm not proposing creating new api here.

how is that any different from normal 'ip netns exec'?
that is expected user behavior.

in container networking based on netns all netns-es are connected
at l2 or l3, whereas socket is l4+ abstraction. Therefore doing
'if (!root_ns) allow' at socket layer is simply broken from security
point of view.

adding 'prog override is not allowed' flag will obviously _not_ break abi.
If program is attached to a cgroup in this mode, the descendants won't
be able to attach. Trivial boolean flag check at attach time.
Just like 'priority' mode will not break it.

what's been missing since the beginning of the thread that cgroup+bpf is
the bpf feature and on bpf side we can handle program chaining with priority
in flexible way. bpf prog needs to be able to attach to descendent
and make sure that the attached program is the only one that makes the
decision. Our main use case is application network analytics and
enforcement when apps are not malicious. In this case the container
management framework will attach one program to a particular
part of the hierarchy and will create whatever necessary combinations
of the programs for descendents, since it's one common framework
for them all and running single program is faster than walking link lists
and doing parsing and IP lookups several times. It's often the case that
prep work like skb parsing and map lookups are common across programs, but
filtering/monitoring logic is different, so dumb link list and call
all programs one by one is inferior. Whereas multiple program combining on
the user space side can be done efficiently.

To summarize, I think the 'prog override is not allowed' flag would be
ok feature to have and I wouldn't mind making it the default when no 'flag'
field is passed to bpf syscall, but it's not acceptable to remove current
'prog override is allowed' behavior.
So if you insist on changing the default, please implement the flag asap.
Though from security point of view and ABI point of view there is absolutely
no difference whether this flag is added today or a year later while
the default is kept as-is.

At this point I don't see a reason to have two APIs.
When bpf_type_cgroup* becomes available to unprivileged users
the same api will work as-is.

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

new file mode 100644

[Nicolas Dichtel]

Here is the v4 of this series. Seems there was too many people cc'ed, so I've
removed arch specific ml. Hope it's better now.

Patches #1 to #4 are just cleanup: some exported headers were still under
a non-uapi directory.
The patch #5 was spotted by code review: there is no in-tree user of this
functionality.
Patches #6 and #7 remove the need to list explicitly headers. Now all files

under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. If I must rebase it against the kbuild

tree, just tell me.

v3 -> v4:
- first patch has been included
- patch #4: get back to v2 and remove arch/x86/include/asm/msr-index.h

[Nicolas Dichtel]

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
- arch-v[10|32] for cris;
- arch for tile.

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):

Thanks to Julien Floret <julien...@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
- include/uapi/asm-generic/Kbuild.asm;
- arch/<arch>/include/uapi/asm/Kbuild;
- arch/<arch>/include/asm/Kbuild.

If these aren't just a mistake in your list the patches need to be
fixed not to install this build system internal file.

And I'm pretty sure I already pointed this out last time.

[Nicolas Dichtel]

Yes, it was already pointed out. But, as I said, this is done for *every*
exported directory. My patch just follows how it is done currently:
$ find . -name '.install' | wc -l
105
$ find . -name '..install.cmd' | wc -l
105
$ find . -type d | wc -l
105

I'm not against removing these files, but this should be done in another patch,
it's not related to this series.
Fell free to send a patch.


Regards,
Nicolas

Why? Why is this damn thing exported in the first place?

The moment we decide to change an MSR name or even remove it from that
file, we break userspace. And what for, because userspace is using some
arbitrary header file which was meant to be for the kernel solely.

It is exported because it is listed in arch/x86/include/uapi/asm/Kbuild:
header-y += msr-index.h (see also patch #4).

I understand your concerns but my patch does not change anything. And I think
David's comment is right: if I remove it, I break the uapi.

After digging a bit, it seems you have already tried to remove it in commit
b72e7464e4cf ("x86/uapi: Do not export <asm/msr-index.h> as part of the user API
headers"), but because this file is still listed in the Kbuild file, it is still
exported.

It would be great if we could find a consensus about what to do with this file
because it blocks patch #4 and the rest of the series.


Thank you,
Nicolas

Oh great. :-\

The reasoning in b72e7464e4cf was valid then and is valid now. This
thing should not have been exported in the first place. And it's not
like I didn't try then. Dammit!

I know, we should not ever break userspace but if it were me, I'd remove
that export and see what breaks. If at all.

But let's see what the others think first.

Yeah, that's a good idea, thanks Christoph.

I guess we'll have to do that if something in userspace has put its
sticky fingers on that file and cannot be fixed. Which I hardly doubt
but we can't break that damn userspace.

A combination of delegation policy (a la subtree_control in the
parent) and MAC policy. I'm quite confident that apparmor can apply
policy to cgroupfs and I'm reasonably confident (although slightly
less so) that selinux can as well. The docs suck :(

But if there's only one file in there to apply MAC policy to, the
ability to differentiate between subsystems is quite limited. In the
current API, there are no files to apply policy to, so it won't work
at all.

I don't know what you mean. open() of the directory can't check
anything useful because it has to work for programs that just want to
read the directory.

# ./ip link add dev vrf0 type vrf table 10

Default binding is "vrf0"
# ./ip vrf exec vrf0 unshare -n ./show_bind
show_bind: getsockopt: No such device

The expected behavior to me is that ip netns exec (or equivalently
unshare -n) gives a clean slate. Actually malfunctioning (which this
example using the latest iproute2 and linux just did) is not expected.

I'm done with this part of this thread and I'm sending a patch.

It can trivially restruct the types of sockets that are created by
filtering on socket(2) syscall parameters, at least on sane
architectures that don't use socketcall().

It's too late and I have too little time. I'll try to write a patch
to change the default to just deny attempts to override. Better
behavior can be added later.

IMO your suggestions about priorities are overcomplicated. For your
instrumentation needs, I can imagine that a simple "make this hook not
run if a descendent has a hook" would do it. For everything else, run
them all in tree order (depending on filter type) and let the eBPF
code do whatever it wants to do.

The importance of uapi headers presence is a bit overrated.

If you look at, for example, iptables (and further projects in that
area), copies of uapi headers have been made (and this process is likely
to continue) because it could be compiled on a variety of vintage
systems that do not have all required #defines yet.

Similarly, it may be built on a variety of _modern_ systems whose
kernels no longer have a particular thing (e.g. ipt_SAME), so it also
ships copies of those headers.

So if some userspace component depends on that particular msr header (which,
unlike ipt_SAME, was not intended for export), is it not reasonable to expect
them to make a copy if and when they need it?

Yeah, either copy the whole header or better yet use own defines.
Especially in this particular case, where we have a bunch of MSRs which
are in the processor manuals. Exporting the defines is pretty pointless
and even disadvantageous for the kernel.

So do you agree with the current patch (a build-fix is also needed :/)?

[Gideon Israel Dsouza]

Folks,

I apologize for the goof ups. I know accepting newbie patches must be
annoying. If it's any consolation I'm trying hard to learn the ropes
with a simple patches so I can contribute more substantial stuff
later.

Thanks,
Gideon

This is resend, I've corrected the mistakes from the last patch.

Added __mode(x) into compiler-gcc.h as part of a cleanup task I've
taken up, to replace gcc specific attributes with macros.

Last accepted patch I sent into linux-next for crypto: d8c34b949d8c:
crypto: Replaced gcc specific attributes with macros from compiler.h

The last commit of this task that went through you: 52f5684c8e1ec
kernel: use macros from compiler.h instead of __attribute__((...))

The next patch is for cleaning up the m68k subsystem and it requires
a new macro to wrap __attribute__ ((mode (...)))

There is <linux/compiler.h> which provides macros for various gcc specific
constructs. Eg: __weak for __attribute__((weak)). I've cleaned all
instances of gcc specific attributes with the right macros for all files
under /arch/m68k

This patch depends on the previous with changes in
/include/linux/compiler-gcc.h

Here on my Fedora system:

$ less /usr/include/asm/msr-index.h
#ifndef _ASM_X86_MSR_INDEX_H
#define _ASM_X86_MSR_INDEX_H

/* CPU model specific register (MSR) numbers */

/* x86-64 specific MSRs */

#define MSR_EFER 0xc0000080 /* extended feature register */

#define MSR_STAR 0xc0000081 /* legacy mode SYSCALL target */

#define MSR_LSTAR 0xc0000082 /* long mode SYSCALL target */

...

Like it or not, it is _already_ exported to userspace, so it forms
part of the user ABI. You can try to remove it from userspace view,
but if anyone has already started to use it, removing it will already
cause a userspace regression.

So, I don't think we have any grounds to NAK these patches on the
basis of "we don't want this to be visible to userspace because it
may cause a userspace regression." Removing it from userspace view
is likely to cause a userspace regression.

This patch just makes sure that such a regression doesn't happen when
kbuild stops exporting files in _non_-uapi directories.

Well, I did try to stop it then too:

b72e7464e4cf ("x86/uapi: Do not export <asm/msr-index.h> as part of the user API headers")

And yet this wankery trickled out to userspace anyway.

Well, if it were me, I'd still remove the header and see if anything
breaks.

If it does - which I doubt very much - we can do Christoph's idea of
leaving the current version of the header exported but then untangling
it from the whole uapi crap and use our own kernel version which we can
change as much as we can.

In the end of the day, it is a maintainer decision what's going to
happen.

Subject: [Patch v5 0/2] Support ARM SMCC SoC vendor quirks

At least one SoC vendor (Qualcomm) requires additional processing done
during ARM SMCCC calls. As such, an additional parameter to the
arm_smccc_smc is required to be able to handle SoC specific quirks.

The Qualcomm quirk is necessary due to the fact that the scm call can
be interrupted on Qualcomm ARM64 platforms. When this occurs, the
call must be restarted using information that was passed back during
the original smc call.

The first patch in this series adds a quirk structure and also adds a
quirk parameter to arm_smccc_smc calls. I added macros to allow users
to choose the API they need. This keeps all of the current users who
do not need quirks from having to change anything.

The second patch adds the Qualcomm quirk and also implements the
Qualcomm firmware changes required to handle the restarting of the
interrupted SMC call.

The original patch set for the SMCCC session ID is located at:
https://lkml.org/lkml/2016/8/20/7

Changes from v4:
- Fix issue with hvc calls.

Changes from v3:
- Fix documentation

Changes from v2:
- Use variadic macros

Changes from v1:
- Add macros to handle both use cases per review comments

Firstly, I believe you are (very!) confused about what forms part of the Linux
user-space ABI - it's not the exported headers but the functionality and how
application _binaries_ rely on it. We have strong ABI guarantees that are in no
header anywhere. And we have tons and tons of details in UAPI headers that are not
part of any system call ABI (or protocol ABI) of Linux.

Note that for example the 'MSR_STAR' definition you quote above is not part of the
ABI, because user-space _cannot make use of it_: it's a privileged CPU register
that only the kernel can write to. There's no system call ABI that Linux defines
that this MSR (or any other MSR for that matter) are part of.

These MSR headers are not part of the ABI - they are part of the _mechanism_
trying to inform user-space about ABIs and people trying to somehow claim that
they are an ABI are confused IMHO.

The point with msr-index.h is that there's no user-space ABI where those MSRs are
enumerated.

Secondly, ABI means 'Application Binary Interface' - note the 'Binary' part. The
ABI cannot be broken, by definition, by putting a header into another place. Now
we do export UAPI headers and we definitely don't want to break user-space tooling
if we can avoid it, but trying to spin the UAPI headers mechanism into an "ABI" is
confused on so many levels.


I.e. this whole discussion is silly in the extreme. The point of the UAPI exports
is to clean up our ABI exports, after we used to export _all_ headers to
user-space.

I.e. by definition the UAPI mechanism is fundamentally about _restricting_ the
amount of headers that are exposed - separating true ABI from random kernel
internals. This process of enumerating ABI details separately from kernel
implementation internal details improves the kernel headers.

> [...] You can try to remove it from userspace view, but if anyone has already

I challenge you to show a single user-space regression from the removal of the
'MSR_STAR' definition for example.

Please explain, why do you want to export msr-index.h and which part of it is an
'ABI' in your opinion? Until you can explain that my NAK stands.

Thanks,

Ingo

[Nicolas Dichtel]

Here is the v5 of this series. Seems there was too many people cc'ed, so I've
removed arch specific ml. Hope it's better now.

Patches #1 and #2 are just cleanup: some exported headers were still under
a non-uapi directory. Patch #3 is a fix to avoid exporting a file that was
not under an uapi directory.
After these three patches, all exported headers are under an uapi directory:
path #4 stops searching files in non uapi directories.
The patch #5 was spotted by code review: there is no in-tree user of this
functionality.
Patch #6 fixes some warnings/errors reported by 0-day tests.
Patches #7 and #8 remove the need to list explicitly headers. Now all files
under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. If I must rebase it against the kbuild
tree, just tell me.

v4 -> v5:
- patch #3: get back to v3 (don't export msr-index.h)
- patch #6: new in this version
- patch #7: fix compilation by introducing header-n

v3 -> v4:
- first patch has been included
- patch #4: get back to v2 and remove arch/x86/include/asm/msr-index.h

v2 -> v3:
- patch #1: remove arch/arm/include/asm/types.h
- patch #2: remove arch/h8300/include/asm/bitsperlong.h
- patch #3: remove arch/nios2/include/uapi/asm/setup.h
- patch #4: don't export msr-index.h
- patch #5: fix a typo: s/unput-files3-name/input-files3-name
- patch #6: no change
- patch #7: fix include/uapi/asm-generic/Kbuild.asm by introducing mandatory-y
- add patch #8

v1 -> v2:
- add patch #1 to #6
- patch #7: remove use of header-y

Comments are welcomed,
Nicolas

[Nicolas Dichtel]

Even if this file was not in an uapi directory, it was exported because
it was listed in the Kbuild file.

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
- arch-v[10|32] for cris;
- arch for tile.

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):

subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
- include/uapi/asm-generic/Kbuild.asm;
- arch/<arch>/include/uapi/asm/Kbuild;
- arch/<arch>/include/asm/Kbuild.

- --- 7.1 header-y
-
- header-y specifies header files to be exported.

- Example:
- #include/linux/Kbuild
- header-y += usb/
- header-y += aio_abi.h
+All headers under include/uapi/, include/generated/uapi/,
+arch/<arch>/include/uapi/asm/ and arch/<arch>/include/generated/uapi/asm/
+are exported.

- The convention is to list one file per line and

- preferably in alphabetic order.

+A Kbuild file may be defined under arch/<arch>/include/uapi/asm/ and
+arch/<arch>/include/asm/ to list asm files coming from asm-generic.
+See subsequent chapter for the syntax of the Kbuild file.

- header-y also specifies which subdirectories to visit.
- A subdirectory is identified by a trailing '/' which
- can be seen in the example above for the usb subdirectory.
+ --- 7.1 header-n

- Subdirectories are visited before their parent directories.
+ header-n is essentially used by include/uapi/linux/Kbuild to avoid
+ exporting specific headers (e.g. kvm.h) on architectures that do not
+ support it. It should be avoided as much as possible.

--- 7.2 genhdr-y

- genhdr-y specifies generated files to be exported.
- Generated files are special as they need to be looked
- up in another directory when doing 'make O=...' builds.
+ genhdr-y specifies asm files to be generated.

Example:
- #include/linux/Kbuild
- genhdr-y += version.h

This header file is exported, but from a userland pov, it's just a wrapper
to asm-generic/setup.h.

I think this is actually wrong -- the socket creation filter appears
to be called only on inet sockets. Is there a good reason for that?

Is there any plan to address this? If not, I'll try to write that
patch this weekend.

I've got an identical patch in my ever growing stack of stuff that I should
actually submit:

yes. I'm working on 'disallow program override' flag.
It got stalled, because netns discussion got stalled.
Later today will send a patch for dev_id+inode and
will continue on the flag patch.
