OK, this looks much better then explicitly exposing NOIO/NOFS to the
userspace. Restricting to CAP_SYS_RESOURCE makes sense as well but I am
not really an expert in that direction.
So for the proposed semantic this makes sense

I think the benefits you point out are not so significant.
The default assumption is that a given piece of memory is
readable and writable.
Does musl use MAP_STACKED? AFAICT, it doesn't.
I suppose it's not that I prefer malloc(), but rather that (first I
was ignorant, and second that) I prefer simplicity. In fact I even
set up a branch to change various pieces of code I had to use
MAP_STACKED, and then had an "if I had thought about this for
30 minutes, I might have saved myself a couple of hours of work"
moment after I researched the history of MAP_STACKED a little.
I still don't know the answer for sure. I'm inclined to
leave things as they are until I hear a compelling
argument to change things.

Not sure what you mean.

No. None of this even means that these objects should be sockets per
se. The point is that anyone who calls recvmsg() and passes a control
buf *must* handle SCM_RIGHTS because even very old Unixes can
materialize file descriptors. The only exception is if the program
knows a priori that the fd refers to a socket that can't use
SCM_RIGHTS.
In other words, failing to handle file descriptors returned by
recvmsg() is an application bug. Failing to handle file descriptors
returned by read() is not an application bug -- it's a kernel bug.

You've misunderstood what you're quoting me as saying. I'm saying
that the issue is worse if you pass the userfaultfd via SCM_RIGHTS to
an unsuspecting program. It is perfectly valid to receive a file
descriptor via SCM_RIGHTS and then call read(), at least so long as
you are okay with potentially blocking.
If you receive a fd to a socket using SCM_RIGHTS and then you fail to
check cmsg_type as above, then you have a bug regardless of
userfaultfd.

Sure. My confusion is why it is a) variadic in the first place and b)
even if it is can't we just advertise it as non-variadic since these
functions will not grow any additional arguments.

Yeah, though I wonder whether this is all so ancient that it doesn't
matter anymore at this point in time.

Apart from MAP_STACK at some point (however unlikely) becoming relevant
I also like that mmap() makes it explicit that the page needs to be
readable (PROT_READ) and writeable (PROT_WRITE) and also every
(relevant) libc I know uses the explicit mmap() in their pthread
implementation. If you prefer the malloc() as an example that's
obviously fine.

This is probably too detailed from my end.
Signals can be either thread-group-directed or thread-directed. That's
one aspect. The other aspect is whether they are delivered
thread-specific or thread-group-wide. While signals can be
thread-group-directed kill() they are not necessarily delivered
thread-group-wide. (I can go into details but that's not necessarily too
useful for this manpage.) My point was just that mentioning fatal
signals (e.g. SIGKILL, SIGSTOP) are always delivered thread-group-wide
no matter if they are thread-group-directed or thread-directed. This
might all be covered by your wording already and I just didn't read
close enough.

It might be worth mentioning that using it with a stack involves more
than just allocating and passing it because people tend to assume that
using the syscall (not the glibc wrapper) with a stack just works. So
it's similar to the TLS comment we added with the difference that once
we have a glibc wrapper for clone3() the stack argument becomes easier
to use.

I do not think nolibc.h is a good starting point. The header is
pretty much incompatible with everything, including multiple
translation units that include it, so including it from
<linux/types.h> will not work.

<stddef.h> is expected to be provided by the compiler. It's probably

After further reading into `nolibc.h` I think not all of it should be
in UAPI (specifically the syscalls wrappers don't).
I think it should be split and both the ASM declarations and the
types(i.e. size_t) should be in UAPI

Hi,
I'm proposing to move `linux/tools/include/nolibc/nolibc.h` to the
UAPI interface.
It would then be included in `linux/types.h`
Would love feedback before I work on a patch.
Thanks.

in effect the entire page! You turned up some useful points

I'm not sure that I understand your confusion. The point is, it's a
variadic function: the extra arguments are only ever touched if the
relevant flags are specified.
Or maybe you just meant: "this should not be a variadic function,
but rather that all 7 arguments should always be specified"? But,
then I think the point is that clone() (and the underlying syscall)
did not always have this number of arguments. Before Linux 2.6, the
wrapper and syscall only had 4 arguments.

True. That text has been in the page for 21 years. It probably needs
a new coat of paint...

A good thought...
I changed the text to read:
Unlike fork(2), these system calls allow the child to be created
with various properties that differ from the parent. For example,
these system calls provide more precise control over what pieces
of execution context are shared between the calling process and
the child process. For example, using these system calls, the
caller can control whether or not the two processes share the vir‐
tual address space, the table of file descriptors, and the table
of signal handlers. These system system calls also allow the new
child process to placed in separate namespaces(7).
Okay?

So, I'm getting a little bit of an education here, and maybe you are
going to further educate me. Long ago, I added the documentation of
MAP_STACK to mmap(2), but I never quite connected the dots.
However, you say MAP_STACK is *usually* a noop. As far as I can see,
in current kernels it is *always* a noop. And AFAICS, since it was first
added in 2.6.27 (2008), it has always been a noop.
I wonder if it will always be a noop.
If we go back and look at the commit:

commit 2fdc86901d2ab30a12402b46238951d2a7891590
Author: Ingo Molnar <mingo@elte.hu>
Date: Wed Aug 13 18:02:18 2008 +0200
x86: add MAP_STACK mmap flag
as per this discussion:
http://lkml.org/lkml/2008/8/12/423
Pardo reported that 64-bit threaded apps, if their stacks exceed the
combined size of ~4GB, slow down drastically in pthread_create() - because
glibc uses MAP_32BIT to allocate the stacks. The use of MAP_32BIT is
a legacy hack - to speed up context switching on certain early model
64-bit P4 CPUs.
So introduce a new flag to be used by glibc instead, to not constrain
64-bit apps like this.
glibc can switch to this new flag straight away - it will be ignored
by the kernel. If those old CPUs ever matter to anyone, support for
it can be implemented.
]]
And see also https://lwn.net/Articles/294642/
So, my understanding from the above is that MAP_STACK was added to
allow a possible fix on some old architectures, should anyone decide it
was worth doing the work of implementing it. But so far, after 12 years,
no one did. It kind of looks like no one ever will (since those old
architectures become less and less relevant).
So, AFAICT, while it's not wrong to tell people to use mmap(MAP_STACKED),
it doesn't provide any benefit (and perhaps never will), and it is a
more clumsy than plain old malloc().
But, it could well be that there's something I still don't know here,
and I'd be interested to get further education.

I agree. The thing is that the clone(2) text was written long before
the section 7 namespaces manual pages, and some duplication occurred.
I've removed this text, and done the same for the corresponding text
in CLONE_NEWNET and CLONE_NEWIPC.

Yes, but CLONE_IDLETASK was never accessible from userspace, as far
as I know. (That is, if you specified that bit in flags, it was
ignored. Rusty's commit message obliquely states this.)

Congratulations :-).
I changed the text here to read:
CLONE_PID (Linux 2.0 to 2.5.15)
If CLONE_PID is set, the child process is created with the
same process ID as the calling process. This is good for
hacking the system, but otherwise of not much use. From
Linux 2.3.21 onward, this flag could be specified only by
the system boot process (PID 0). The flag disappeared com‐
pletely from the kernel sources in Linux 2.5.16. Subse‐
quently, the kernel silently ignored this bit if it was
specified in the flags mask. Much later, the same bit was
recycled for use as the CLONE_PIDFD flag.

Okay -- but *you* added this text to the man page ;-).
So, here's what I have done.
15 years after its demise, CLONE_DETACHED gets equal status with
other flags in the manual page:
CLONE_DETACHED (historical)
For a while (during the Linux 2.5 development series) there
was a CLONE_DETACHED flag, which caused the parent not to
receive a signal when the child terminated. Ultimately,
the effect of this flag was subsumed under the CLONE_THREAD
flag and by the time Linux 2.6.0 was released, this flag
had no effect. Starting in Linux 2.6.2, the need to give
this flag together with CLONE_THREAD disappeared.
This flag is still defined, but it is usually ignored when
calling clone(). However, see the description of
CLONE_PIDFD for some exceptions.
And then under CLONE_PIDFD, I have:
If the obsolete CLONE_DETACHED flag is specified alongside
CLONE_PIDFD when calling clone(), an error is returned. An
error also results if CLONE_DETACHED is specified when
calling clone3(). This error behavior ensures that the bit
corresponding to CLONE_DETACHED can be reused for further
PID file descriptor features in the future.
Okay?

I added:
Use of this flag requires detailed knowledge and generally it

Thanks. I made it:
In contrast to the glibc wrapper, the raw clone() system call
accepts NULL as a stack argument (and clone3() likewise allows
cl_args.stack to be NULL). In this case, the child uses a dupli‐
cate of the parent's stack. [...]

I added this sentence:
Although a stack_size argument is provided, stack must still point

* [PATCH 23/23] y2038: allow disabling time32 system calls
From: Arnd Bergmann @ 2019-11-08 21:12 UTC (permalink / raw)
To: y2038
Cc: linux-kernel, Arnd Bergmann, Ingo Molnar, Peter Zijlstra,

In-Reply-To: <20191108210236.1296047-1-arnd@arndb.de>
At the moment, the compilation of the old time32 system calls depends
purely on the architecture. As systems with new libc based on 64-bit
time_t are getting deployed, even architectures that previously supported
these (notably x86-32 and arm32 but also many others) no longer depend on
them, and removing them from a kernel image results in a smaller kernel
binary, the same way we can leave out many other optional system calls.
More importantly, on an embedded system that needs to keep working
beyond year 2038, any user space program calling these system calls
is likely a bug, so removing them from the kernel image does provide
an extra debugging help for finding broken applications.
I've gone back and forth on hiding this option unless CONFIG_EXPERT
is set. This version leaves it visible based on the logic that
eventually it will be turned off indefinitely.

The compat_get_timeval() and timeval_valid() interfaces
are deprecated and getting removed along with the definition
of struct timeval itself.
Change the two implementations of the settimeofday()
system call to open-code these helpers and completely
avoid references to timeval.

* [PATCH 12/23] y2038: syscalls: change remaining timeval to __kernel_old_timeval
From: Arnd Bergmann @ 2019-11-08 21:12 UTC (permalink / raw)
To: y2038, Benjamin Herrenschmidt, Paul Mackerras, Michael Ellerman,
Alexander Viro, Rafael J. Wysocki, Pavel Machek, Len Brown,
John Stultz, Thomas Gleixner
Cc: linux-kernel, Arnd Bergmann, Stephen Boyd, Christian Brauner,
linuxppc-dev, linux-fsdevel, linux-api, linux-pm
In-Reply-To: <20191108210236.1296047-1-arnd@arndb.de>
All of the remaining syscalls that pass a timeval (gettimeofday, utime,
futimesat) can trivially be changed to pass a __kernel_old_timeval
instead, which has a compatible layout, but avoids ambiguity with
the timeval type in user space.

* [PATCH 10/23] y2038: uapi: change __kernel_time_t to __kernel_old_time_t
From: Arnd Bergmann @ 2019-11-08 21:12 UTC (permalink / raw)
To: y2038, John Stultz, Thomas Gleixner
Cc: linux-kernel, Arnd Bergmann, Stephen Boyd, David Howells, Al Viro,
Deepa Dinamani, Christian Brauner, linux-api
In-Reply-To: <20191108210236.1296047-1-arnd@arndb.de>
This is mainly a patch for clarification, and to let us remove
the time_t definition from the kernel to prevent new users from
creeping in that might not be y2038-safe.
All remaining uses of 'time_t' or '__kernel_time_t' are part of
the user API that cannot be changed by that either have a
replacement or that do not suffer from the y2038 overflow.

* [PATCH 00/23] y2038 cleanups
From: Arnd Bergmann @ 2019-11-08 21:02 UTC (permalink / raw)
To: y2038
Cc: linux-kernel, Arnd Bergmann, rth, tony.luck, paul.burton,
green.hu, deller, mpe, davem, tglx, x86, jdike, richard, viro,
bcrl, john.stultz, sboyd, rostedt, vincenzo.frascino, paul, sds,

This is a series of cleanups for the y2038 work, mostly intended
for namespace cleaning: the kernel defines the traditional
time_t, timeval and timespec types that often lead to y2038-unsafe
code. Even though the unsafe usage is mostly gone from the kernel,
having the types and associated functions around means that we
can still grow new users, and that we may be missing conversions
to safe types that actually matter.
As there is no rush on any of these patches, I would either
queue them up in linux-next through my y2038 branch, or
Thomas could add them to the tip tree if he wants.
As mentioned in another series, this is part of a larger
effort to fix all the remaining bits and pieces that are
not completed yet from the y2038 conversion, and the full
set can be found at:
https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=y2038-endgame
Maintainers, please review and provide Acks.
Let me know if you have any opinion on whether we should do
the include last two patches of this series or not.

Fundamentally, fs-verity guarantees that all data read is verified against a
cryptographic hash that covers the entire file. I think it will be helpful to
convey that here, e.g. to avoid confusion with non-cryptographic, individual
block checksums supported by filesystems like btrfs and zfs.
Now, the only sane way to implement this model is with a Merkle tree, and this
is part of the fs-verity UAPI (via the file hash), so that's where I'm coming
from here. Perhaps the phrase "Merkle tree" could be interpreted too strictly,
though, so it would be better to emphasize the more abstract model. How about
the following?:
The file has fs-verity enabled. It cannot be written to, and all reads
from it will be verified against a cryptographic hash that covers the
entire file, e.g. via a Merkle tree.

Agreed. I was just thinking out loud that it seems like much of what
we need could be a generic library mechanism similar to, but not quite
like, the existing idr code.

Yes, just "cont" is a bit too ambiguous considering we have both
integer values and structures being passed around. Whatever you
decide on, a common base with separate suffixes seems like a good
idea.
FWIW, I still think the "audit container ID" : "ACID" thing is kinda funny ;)

Generally kernel functions which are "special"/private/unsafe/etc.
have a one, or two, underscore prefix. If you don't want to add the
prefix, that's fine, but please change the name as mentioned
previously.

What protects you from info->cont going away between when you fetch
the pointer via audit_cont() to when you dereference it in
refcount_inc()?

Please document the relationship between the two, I worry we could

These were genuine questions, I'm not suggesting anything in
particular, I'm just curious about how we handle an orchestrator that
isn't continuously running ... is this possible? Do we care?

Okay, let's just drop it. I *really* don't like this approach of
tossing questionable stuff at the end of the patchset; I get why you
are doing it, but I think we really need to focus on keeping this
changeset small. If the number of ACIDs (heh) become unwieldy the
right solution is to improve the algorithms/structures, if we can't do
that for some reason, *then* we can fall back to a limiting knob in a
latter release.

Until we have a better idea of how this is going to be used, I think
it's okay for now. It's also internal to the kernel so we can change
it at any time. My comments about the locking/structs was only to try
and think of some reason why one might want to limit the number of
ACIDs since neither you or Eric provided any reasoning that I could
see.

[side note #1: Sorry for the delay, travel/conferences have limited my
time and I felt we needed to focus on the larger issue of
netlink/procfs first. Back to the other topics ...]
[side note #2: I just realized that one can shorten "audit container
ID" to ACID, I think that's going to be my favorite realization of the
day :)]
My concern wasn't really about the availability of the data, since as
you said, it is copied into the record buffer, but rather a delay
between when the audit container ID (ACID) disappears from the
tracking/list db in the kernel to when it is emitted in an audit
record from the kernel. During this time is seems like it could be
possible for the orchestrator to reintroduce the same ACID value and
if someone is not taking into account the full audit history they
could get confused (the full audit history should show the proper
creation/destruction events in the correct order). Ultimately I'm not
sure it is a major issue, and fixing it is likely to be really ugly,
but I think it would be good to add some comments in the code
regarding what we guarantee as far as ACID lifetimes are concerned.

OK, this is indeed the signature defined by the kernel API. What happen
if this API change (e.g. if struct sock is replaced with a struct
sock_meta)?

How does the verifier know a given BPF attachment point for a program
without relying on its type or attach type? How and where is registered
this mapping?
To say it another way, if there is no way to differentiate two program
targeting different hook, I don't understand how the verifier could
check if a given program can legitimately call a helper which could read
the tracer and tracee fields (legitimate for a ptrace hook), whereas
this program may be attached to a sock_rcv_skb hook (and there is no way
to know that).

I mentioned runtime check because I though a helper should handle the

This and some of the other questions (about the core-framework and
guiding principles) are better discussed in the context of the
new-patchset. It might take us some-time as I am on vacation for the
next few weeks and some of the other members are traveling.

Yes, that's correct and based on the feedback we got on the RFC v1
at the Linux Plumbers 2019.
Also, the changes that allow BPF verifier to use the
BTF information to validate accesses and dynamically populate the
context are very recent and have influenced the design for the
next iteration.

Lets take security_sock_rcv_skb(struct sock *sk, struct sk_buff *skb)
as one specific example here: the running kernel has its own internal
btf_vmlinux and therefore a complete description of itself. From verifier
side we can retrieve & introspect the security_sock_rcv_skb signatue and
thus know that the given BPF attachment point has struct sock and struct
sk_buff as input arguments which can then be accessed generically by the
prog in order to allow sk_filter_trim_cap() to pass or to drop the skb.
The same generic approach can be done for many of the other lsm hooks, so
single program type would be enough there and context is derived automatically,
no dedicated extra context per attach type would be needed and no runtime
checks as you mentioned above since its still all asserted at verification
time.
Thanks,
Daniel
