rfkill: revert back to old userspace API by default
Recompiling with the new extended version of struct rfkill_event broke systemd in *two* ways: - It used "sizeof(struct rfkill_event)" to read the event, but then complained if it actually got something != 8, this broke it on new kernels (that include the updated API); - It used sizeof(struct rfkill_event) to write a command, but didn't implement the intended expansion protocol where the kernel returns only how many bytes it accepted, and errored out due to the unexpected smaller size on kernels that didn't include the updated API. Even though systemd has now been fixed, that fix may not be always deployed, and other applications could potentially have similar issues. As such, in the interest of avoiding regressions, revert the default API "struct rfkill_event" back to the original size. Instead, add a new "struct rfkill_event_ext" that extends it by the new field, and even more clearly document that applications should be prepared for extensions in two ways: * write might only accept fewer bytes on older kernels, and will return how many to let userspace know which data may have been ignored; * read might return anything between 8 (the original size) and whatever size the application sized its buffer at, indicating how much event data was supported by the kernel. Perhaps that will help avoid such issues in the future and we won't have to come up with another version of the struct if we ever need to extend it again. Applications that want to take advantage of the new field will have to be modified to use struct rfkill_event_ext instead now, which comes with the danger of them having already been updated to use it from 'struct rfkill_event', but I found no evidence of that, and it's still relatively new.

fuse: 32-bit user space ioctl compat for fuse device
With a 64-bit kernel build the FUSE device cannot handle ioctl requests coming from 32-bit user space. This is due to the ioctl command translation that generates different command identifiers that thus cannot be used for direct comparisons without proper manipulation. Explicitly extract type and number from the ioctl command to enable 32-bit user space compatibility on 64-bit kernel builds.

bpf: BPF-helper for MTU checking add length input
The FIB lookup example[1] show how the IP-header field tot_len
(iph->tot_len) is used as input to perform the MTU check.
This patch extend the BPF-helper bpf_check_mtu() with the same ability
to provide the length as user parameter input, via mtu_len parameter.
This still needs to be done before the bpf_check_mtu() helper API
becomes frozen.

KVM: x86/xen: Add support for vCPU runstate information
This is how Xen guests do steal time accounting. The hypervisor records the amount of time spent in each of running/runnable/blocked/offline states. In the Xen accounting, a vCPU is still in state RUNSTATE_running while in Xen for a hypercall or I/O trap, etc. Only if Xen explicitly schedules does the state become RUNSTATE_blocked. In KVM this means that even when the vCPU exits the kvm_run loop, the state remains RUNSTATE_running. The VMM can explicitly set the vCPU to RUNSTATE_blocked by using the KVM_XEN_VCPU_ATTR_TYPE_RUNSTATE_CURRENT attribute, and can also use KVM_XEN_VCPU_ATTR_TYPE_RUNSTATE_ADJUST to retrospectively add a given amount of time to the blocked state and subtract it from the running state. The state_entry_time corresponds to get_kvmclock_ns() at the time the vCPU entered the current state, and the total times of all four states should always add up to state_entry_time.

Merge tag 'io_uring-worker.v3-2021-02-25' of git://git.kernel.dk/linux-block
Pull io_uring thread rewrite from Jens Axboe:
"This converts the io-wq workers to be forked off the tasks in question
instead of being kernel threads that assume various bits of the
original task identity.
This kills > 400 lines of code from io_uring/io-wq, and it's the worst
part of the code. We've had several bugs in this area, and the worry
is always that we could be missing some pieces for file types doing
unusual things (recent /dev/tty example comes to mind, userfaultfd
reads installing file descriptors is another fun one... - both of
which need special handling, and I bet it's not the last weird oddity
we'll find).
With these identical workers, we can have full confidence that we're
never missing anything. That, in itself, is a huge win. Outside of
that, it's also more efficient since we're not wasting space and code
on tracking state, or switching between different states.
I'm sure we're going to find little things to patch up after this
series, but testing has been pretty thorough, from the usual
regression suite to production. Any issue that may crop up should be
manageable.
There's also a nice series of further reductions we can do on top of
this, but I wanted to get the meat of it out sooner rather than later.
The general worry here isn't that it's fundamentally broken. Most of
the little issues we've found over the last week have been related to
just changes in how thread startup/exit is done, since that's the main
difference between using kthreads and these kinds of threads. In fact,
if all goes according to plan, I want to get this into the 5.10 and
5.11 stable branches as well.
That said, the changes outside of io_uring/io-wq are:
- arch setup, simple one-liner to each arch copy_thread()
implementation.
- Removal of net and proc restrictions for io_uring, they are no
longer needed or useful"

numa balancing: migrate on fault among multiple bound nodes
Now, NUMA balancing can only optimize the page placement among the NUMA
nodes if the default memory policy is used. Because the memory policy
specified explicitly should take precedence. But this seems too strict in
some situations. For example, on a system with 4 NUMA nodes, if the
memory of an application is bound to the node 0 and 1, NUMA balancing can
potentially migrate the pages between the node 0 and 1 to reduce
cross-node accessing without breaking the explicit memory binding policy.
So in this patch, we add MPOL_F_NUMA_BALANCING mode flag to
set_mempolicy() when mode is MPOL_BIND. With the flag specified, NUMA
balancing will be enabled within the thread to optimize the page placement
within the constrains of the specified memory binding policy. With the
newly added flag, the NUMA balancing control mechanism becomes,
- sysctl knob numa_balancing can enable/disable the NUMA balancing
globally.
- even if sysctl numa_balancing is enabled, the NUMA balancing will be
disabled for the memory areas or applications with the explicit
memory policy by default.
- MPOL_F_NUMA_BALANCING can be used to enable the NUMA balancing for
the applications when specifying the explicit memory policy
(MPOL_BIND).
Various page placement optimization based on the NUMA balancing can be
done with these flags. As the first step, in this patch, if the memory of
the application is bound to multiple nodes (MPOL_BIND), and in the hint
page fault handler the accessing node are in the policy nodemask, the page
will be tried to be migrated to the accessing node to reduce the
cross-node accessing.
If the newly added MPOL_F_NUMA_BALANCING flag is specified by an
application on an old kernel version without its support, set_mempolicy()
will return -1 and errno will be set to EINVAL. The application can use
this behavior to run on both old and new kernel versions.
And if the MPOL_F_NUMA_BALANCING flag is specified for the mode other than
MPOL_BIND, set_mempolicy() will return -1 and errno will be set to EINVAL
as before. Because we don't support optimization based on the NUMA
balancing for these modes.
In the previous version of the patch, we tried to reuse MPOL_MF_LAZY for
mbind(). But that flag is tied to MPOL_MF_MOVE.*, so it seems not a good
API/ABI for the purpose of the patch.
And because it's not clear whether it's necessary to enable NUMA balancing
for a specific memory area inside an application, so we only add the flag
at the thread level (set_mempolicy()) instead of the memory area level
(mbind()). We can do that when it become necessary.
To test the patch, we run a test case as follows on a 4-node machine with
192 GB memory (48 GB per node).
1. Change pmbench memory accessing benchmark to call set_mempolicy()
to bind its memory to node 1 and 3 and enable NUMA balancing. Some
related code snippets are as follows,
#include <numaif.h>
#include <numa.h>
struct bitmask *bmp;
int ret;
bmp = numa_parse_nodestring("1,3");
ret = set_mempolicy(MPOL_BIND | MPOL_F_NUMA_BALANCING,
bmp->maskp, bmp->size + 1);
/* If MPOL_F_NUMA_BALANCING isn't supported, fall back to MPOL_BIND */
if (ret < 0 && errno == EINVAL)
ret = set_mempolicy(MPOL_BIND, bmp->maskp, bmp->size + 1);
if (ret < 0) {
perror("Failed to call set_mempolicy");
exit(-1);
}
2. Run a memory eater on node 3 to use 40 GB memory before running pmbench.
3. Run pmbench with 64 processes, the working-set size of each process
is 640 MB, so the total working-set size is 64 * 640 MB = 40 GB. The
CPU and the memory (as in step 1.) of all pmbench processes is bound
to node 1 and 3. So, after CPU usage is balanced, some pmbench
processes run on the CPUs of the node 3 will access the memory of
the node 1.
4. After the pmbench processes run for 100 seconds, kill the memory
eater. Now it's possible for some pmbench processes to migrate
their pages from node 1 to node 3 to reduce cross-node accessing.
Test results show that, with the patch, the pages can be migrated from
node 1 to node 3 after killing the memory eater, and the pmbench score
can increase about 17.5%.

Char/Misc driver patches for 5.12-rc1
Here is the large set of char/misc/whatever driver subsystem updates for
5.12-rc1. Over time it seems like this tree is collecting more and more
tiny driver subsystems in one place, making it easier for those
maintainers, which is why this is getting larger.
Included in here are:
- coresight driver updates
- habannalabs driver updates
- virtual acrn driver addition (proper acks from the x86
maintainers)
- broadcom misc driver addition
- speakup driver updates
- soundwire driver updates
- fpga driver updates
- amba driver updates
- mei driver updates
- vfio driver updates
- greybus driver updates
- nvmeem driver updates
- phy driver updates
- mhi driver updates
- interconnect driver udpates
- fsl-mc bus driver updates
- random driver fix
- some small misc driver updates (rtsx, pvpanic, etc.)
All of these have been in linux-next for a while, with the only reported
issue being a merge conflict in include/linux/mod_devicetable.h that you
will hit in your tree due to the dfl_device_id addition from the fpga
subsystem in here. The resolution should be simple.

cxl for 5.12
Introduce an initial driver for CXL 2.0 Type-3 Memory Devices. CXL is Compute Express Link which released the 2.0 specification in November. The Linux relevant changes in CXL 2.0 are support for an OS to dynamically assign address space to memory devices, support for switches, persistent memory, and hotplug. A Type-3 Memory Device is a PCI enumerated device presenting the CXL Memory Device Class Code and implementing the CXL.mem protocol. CXL.mem allows device to advertise CPU and I/O coherent memory to the system, i.e. typical "System RAM" and "Persistent Memory" in Linux /proc/iomem terms. In addition to the CXL.mem fast path there is an administrative command hardware mailbox interface for maintenance and provisioning. It is this command interface that is the focus of the initial driver. With this driver a CXL device that is mapped by the BIOS can be administered by Linux. Linux support for CXL PMEM and dynamic CXL address space management are to be implemented post v5.12. |

io_uring: flag new native workers with IORING_FEAT_NATIVE_WORKERS
A few reasons to do this: - The naming of the manager and worker have changed. That's a user visible change, so makes sense to flag it. - Opening certain files that use ->signal (like /proc/self or /dev/tty) now works, and the flag tells the application upfront that this is the case. - Related to the above, using signalfd will now work as well.

Merge tag 'idmapped-mounts-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull idmapped mounts from Christian Brauner:
"This introduces idmapped mounts which has been in the making for some
time. Simply put, different mounts can expose the same file or
directory with different ownership. This initial implementation comes
with ports for fat, ext4 and with Christoph's port for xfs with more
filesystems being actively worked on by independent people and
maintainers.
Idmapping mounts handle a wide range of long standing use-cases. Here
are just a few:
- Idmapped mounts make it possible to easily share files between
multiple users or multiple machines especially in complex
scenarios. For example, idmapped mounts will be used in the
implementation of portable home directories in
systemd-homed.service(8) where they allow users to move their home
directory to an external storage device and use it on multiple
computers where they are assigned different uids and gids. This
effectively makes it possible to assign random uids and gids at
login time.
- It is possible to share files from the host with unprivileged
containers without having to change ownership permanently through
chown(2).
- It is possible to idmap a container's rootfs and without having to
mangle every file. For example, Chromebooks use it to share the
user's Download folder with their unprivileged containers in their
Linux subsystem.
- It is possible to share files between containers with
non-overlapping idmappings.
- Filesystem that lack a proper concept of ownership such as fat can
use idmapped mounts to implement discretionary access (DAC)
permission checking.
- They allow users to efficiently changing ownership on a per-mount
basis without having to (recursively) chown(2) all files. In
contrast to chown (2) changing ownership of large sets of files is
instantenous with idmapped mounts. This is especially useful when
ownership of a whole root filesystem of a virtual machine or
container is changed. With idmapped mounts a single syscall
mount_setattr syscall will be sufficient to change the ownership of
all files.
- Idmapped mounts always take the current ownership into account as
idmappings specify what a given uid or gid is supposed to be mapped
to. This contrasts with the chown(2) syscall which cannot by itself
take the current ownership of the files it changes into account. It
simply changes the ownership to the specified uid and gid. This is
especially problematic when recursively chown(2)ing a large set of
files which is commong with the aforementioned portable home
directory and container and vm scenario.
- Idmapped mounts allow to change ownership locally, restricting it
to specific mounts, and temporarily as the ownership changes only
apply as long as the mount exists.
Several userspace projects have either already put up patches and
pull-requests for this feature or will do so should you decide to pull
this:
- systemd: In a wide variety of scenarios but especially right away
in their implementation of portable home directories.
https://systemd.io/HOME_DIRECTORY/
- container runtimes: containerd, runC, LXD:To share data between
host and unprivileged containers, unprivileged and privileged
containers, etc. The pull request for idmapped mounts support in
containerd, the default Kubernetes runtime is already up for quite
a while now: https://github.com/containerd/containerd/pull/4734
- The virtio-fs developers and several users have expressed interest
in using this feature with virtual machines once virtio-fs is
ported.
- ChromeOS: Sharing host-directories with unprivileged containers.
I've tightly synced with all those projects and all of those listed
here have also expressed their need/desire for this feature on the
mailing list. For more info on how people use this there's a bunch of
talks about this too. Here's just two recent ones:
https://www.cncf.io/wp-content/uploads/2020/12/Rootless-Containers-in-Gitpod.pdf
https://fosdem.org/2021/schedule/event/containers_idmap/
This comes with an extensive xfstests suite covering both ext4 and
xfs:
https://git.kernel.org/brauner/xfstests-dev/h/idmapped_mounts
It covers truncation, creation, opening, xattrs, vfscaps, setid
execution, setgid inheritance and more both with idmapped and
non-idmapped mounts. It already helped to discover an unrelated xfs
setgid inheritance bug which has since been fixed in mainline. It will
be sent for inclusion with the xfstests project should you decide to
merge this.
In order to support per-mount idmappings vfsmounts are marked with
user namespaces. The idmapping of the user namespace will be used to
map the ids of vfs objects when they are accessed through that mount.
By default all vfsmounts are marked with the initial user namespace.
The initial user namespace is used to indicate that a mount is not
idmapped. All operations behave as before and this is verified in the
testsuite.
Based on prior discussions we want to attach the whole user namespace
and not just a dedicated idmapping struct. This allows us to reuse all
the helpers that already exist for dealing with idmappings instead of
introducing a whole new range of helpers. In addition, if we decide in
the future that we are confident enough to enable unprivileged users
to setup idmapped mounts the permission checking can take into account
whether the caller is privileged in the user namespace the mount is
currently marked with.
The user namespace the mount will be marked with can be specified by
passing a file descriptor refering to the user namespace as an
argument to the new mount_setattr() syscall together with the new
MOUNT_ATTR_IDMAP flag. The system call follows the openat2() pattern
of extensibility.
The following conditions must be met in order to create an idmapped
mount:
- The caller must currently have the CAP_SYS_ADMIN capability in the
user namespace the underlying filesystem has been mounted in.
- The underlying filesystem must support idmapped mounts.
- The mount must not already be idmapped. This also implies that the
idmapping of a mount cannot be altered once it has been idmapped.
- The mount must be a detached/anonymous mount, i.e. it must have
been created by calling open_tree() with the OPEN_TREE_CLONE flag
and it must not already have been visible in the filesystem.
The last two points guarantee easier semantics for userspace and the
kernel and make the implementation significantly simpler.
By default vfsmounts are marked with the initial user namespace and no
behavioral or performance changes are observed.

vdpa: Define vdpa mgmt device, ops and a netlink interface
To add one or more VDPA devices, define a management device which
allows adding or removing vdpa device. A management device defines
set of callbacks to manage vdpa devices.
To begin with, it defines add and remove callbacks through which a user
defined vdpa device can be added or removed.
A unique management device is identified by its unique handle identified
by management device name and optionally the bus name.
Hence, introduce routine through which driver can register a
management device and its callback operations for adding and remove
a vdpa device.
Introduce vdpa netlink socket family so that user can query management
device and its attributes.
Example of show vdpa management device which allows creating vdpa device of
networking class (device id = 0x1) of virtio specification 1.1

Pull rdma updates from Jason Gunthorpe:
"This is quite a small cycle, if not for Lee's 70 patches cleaning the
kdocs it would be well below typical for patch count.
Most of the interesting work here was in the HNS and rxe drivers which
got fairly major internal changes.
Summary:
- Driver updates and bug fixes: siw, hns, bnxt_re, mlx5, efa
- Significant rework in rxe to get it ready to have XRC support added
- Several rts bug fixes
- Big series to get to 'make W=1' cleanness, primarily updating kdocs
- Support for creating a RDMA MR from a DMABUF fd to allow PCI peer
to peer transfers to GPU VRAM
- Device disassociation now works properly with umad
- Work to support more than 255 ports on a RDMA device
- Further support for the new HNS HIP09 hardware
- Coding style cleanups: comma to semicolon, unneded semicolon/blank
lines, remove 'h' printk format, don't check for NULL before kfree,
use true/false for bool"

spi: Updates for v5.12
The main focus of this release from a framework point of view has been
spi-mem where we've acquired support for a few new hardware features
which enable better performance on suitable hardware. Otherwise mostly
thanks to Arnd's cleanup efforts on old platforms we've removed several
obsolete drivers which just about balance out the newer drivers we've
added this cycle.
- Allow drivers to flag if they are unidirectional.
- Support for DTR mode and hardware acceleration of dummy cycles in spi-mem.
- Support for Allwinder H616, Intel Lightning Mountain, nVidia Tegra
QuadSPI, Realtek RTL838x and RTL839x.
- Removal of obsolute EFM32, Txx9 and SIRF Prima and Atlas drivers.
