selftests: Test the new RISC-V hwprobe interface
This adds a test for the recently added RISC-V interface for probing hardware capabilities. It happens to be the first selftest we have for RISC-V, so I've added some infrastructure for those as well.

selftests: prctl: Add new prctl test for PR_SET_VMA action
This patch will add the new test, which covers the prctl call with PR_SET_VMA command. The test tries to give a name to the anonymous VMA within the process memory map, and then checks the result of the operation by parsing 'maps' virtual file. Additionally, the test tries to call the prctl PR_SET_VMA command with invalid arguments, and checks the error codes for correctness. At the moment anonymous VMA naming through prctl call functionality is not covered with any tests, so I think implementing it makes sense. In version 2 of this patch I consider the selftest Makefile rule about TARGETS entries order - I moved the 'prctl' entry in the Makefile to follow the lexicographic order. In version 1 it was placed at the end of the list. Signed-off-by: Ivan Orlov <ivan.orlov0322@gmail.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org> |

selftests: use printf instead of echo -ne
Rather than trying to guess which implementation of "echo" to run with
support for "-ne" options, use "printf" instead of "echo -ne". It
handles escape characters as a standard feature and it is widespread
among modern shells.

selftests: find echo binary to use -ne options
Find the actual echo binary using $(which echo) and use it for
formatted output with -ne. On some systems, the default echo command
doesn't handle the -e option and the output looks like this (arm64
build):
-ne Emit Tests for alsa
-ne Emit Tests for amd-pstate
-ne Emit Tests for arm64
This is for example the case with the KernelCI Docker images
e.g. kernelci/gcc-10:x86-kselftest-kernelci. With the actual echo
binary (e.g. in /bin/echo), the output is formatted as expected (x86
build this time):
Emit Tests for alsa
Emit Tests for amd-pstate
Skipping non-existent dir: arm64
Only the install target is using "echo -ne" so keep the $ECHO variable
local to it.

iommufd for 6.2
iommufd is the user API to control the IOMMU subsystem as it relates to managing IO page tables that point at user space memory. It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO container) which is the VFIO specific interface for a similar idea. We see a broad need for extended features, some being highly IOMMU device specific: - Binding iommu_domain's to PASID/SSID - Userspace IO page tables, for ARM, x86 and S390 - Kernel bypassed invalidation of user page tables - Re-use of the KVM page table in the IOMMU - Dirty page tracking in the IOMMU - Runtime Increase/Decrease of IOPTE size - PRI support with faults resolved in userspace Many of these HW features exist to support VM use cases - for instance the combination of PASID, PRI and Userspace IO Page Tables allows an implementation of DMA Shared Virtual Addressing (vSVA) within a guest. Dirty tracking enables VM live migration with SRIOV devices and PASID support allow creating "scalable IOV" devices, among other things. As these features are fundamental to a VM platform they need to be uniformly exposed to all the driver families that do DMA into VMs, which is currently VFIO and VDPA. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRRRCHOFoQz/8F5bUaFwuHvBreFYQUCY5ct7wAKCRCFwuHvBreF YZZ5AQDciXfcgXLt0UBEmWupNb0f/asT6tk717pdsKm8kAZMNAEAsIyLiKT5HqGl s7fAu+CQ1pr9+9NKGevD+frw8Solsw4= =jJkd -----END PGP SIGNATURE----- Merge tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd Pull iommufd implementation from Jason Gunthorpe: "iommufd is the user API to control the IOMMU subsystem as it relates to managing IO page tables that point at user space memory.

Networking changes for 6.2.
Core
----
- Allow live renaming when an interface is up
- Add retpoline wrappers for tc, improving considerably the
performances of complex queue discipline configurations.
- Add inet drop monitor support.
- A few GRO performance improvements.
- Add infrastructure for atomic dev stats, addressing long standing
data races.
- De-duplicate common code between OVS and conntrack offloading
infrastructure.
- A bunch of UBSAN_BOUNDS/FORTIFY_SOURCE improvements.
- Netfilter: introduce packet parser for tunneled packets
- Replace IPVS timer-based estimators with kthreads to scale up
the workload with the number of available CPUs.
- Add the helper support for connection-tracking OVS offload.
BPF
---
- Support for user defined BPF objects: the use case is to allocate
own objects, build own object hierarchies and use the building
blocks to build own data structures flexibly, for example, linked
lists in BPF.
- Make cgroup local storage available to non-cgroup attached BPF
programs.
- Avoid unnecessary deadlock detection and failures wrt BPF task
storage helpers.
- A relevant bunch of BPF verifier fixes and improvements.
- Veristat tool improvements to support custom filtering, sorting,
and replay of results.
- Add LLVM disassembler as default library for dumping JITed code.
- Lots of new BPF documentation for various BPF maps.
- Add bpf_rcu_read_{,un}lock() support for sleepable programs.
- Add RCU grace period chaining to BPF to wait for the completion

iommufd: Add a selftest
Cover the essential functionality of the iommufd with a directed test from userspace. This aims to achieve reasonable functional coverage using the in-kernel self test framework. A second test does a failure injection sweep of the success paths to study error unwind behaviors. This allows achieving high coverage of the corner cases in pages.c. The selftest requires CONFIG_IOMMUFD_TEST to be enabled, and several huge pages which may require: echo 4 > /proc/sys/vm/nr_hugepages Link: https://lore.kernel.org/r/19-v6-a196d26f289e+11787-iommufd_jgg@nvidia.com Tested-by: Nicolin Chen <nicolinc@nvidia.com> Tested-by: Matthew Rosato <mjrosato@linux.ibm.com> # s390 Tested-by: Yi Liu <yi.l.liu@intel.com> Tested-by: Eric Auger <eric.auger@redhat.com> # aarch64 Signed-off-by: Nicolin Chen <nicolinc@nvidia.com> Signed-off-by: Yi Liu <yi.l.liu@intel.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> |

selftests/tdx: Test TDX attestation GetReport support
Attestation is used to verify the trustworthiness of a TDX guest. During the guest bring-up, the Intel TDX module measures and records the initial contents and configuration of the guest, and at runtime, guest software uses runtime measurement registers (RMTRs) to measure and record details related to kernel image, command line params, ACPI tables, initrd, etc. At guest runtime, the attestation process is used to attest to these measurements. The first step in the TDX attestation process is to get the TDREPORT data. It is a fixed size data structure generated by the TDX module which includes the above mentioned measurements data, a MAC ID to protect the integrity of the TDREPORT, and a 64-Byte of user specified data passed during TDREPORT request which can uniquely identify the TDREPORT. Intel's TDX guest driver exposes TDX_CMD_GET_REPORT0 IOCTL interface to enable guest userspace to get the TDREPORT subtype 0. Add a kernel self test module to test this ABI and verify the validity of the generated TDREPORT.

selftests: add tests for the HID-bpf initial implementation
The tests are pretty basic: - create a virtual uhid device that no userspace will like (to not mess up the running system) - attach a BPF prog to it - open the matching hidraw node - inject one event and check: * that the BPF program can do something on the event stream * can modify the event stream - add another test where we attach/detach BPF programs to see if we get errors Note: the Makefile is extracted from selftests/bpf so we can rebuild the libbpf and bpftool components from the current kernel tree without relying on system installed components.

selftests: drop khdr make target
Drop the "khdr" make target as it fails when the build directory is a
sub-directory of the source tree. Rely on the "headers_install"
target to have been run first instead.
For example, here's a typical error this patch is addressing:
$ make O=build -j32 kselftest-gen_tar
make[1]: Entering directory '/home/kernelci/linux/build'
make --no-builtin-rules INSTALL_HDR_PATH=/home/kernelci/linux/build/usr \
ARCH=x86 -C ../../.. headers_install
make[3]: Entering directory '/home/kernelci/linux'
Makefile:1022: ../scripts/Makefile.extrawarn: No such file or directory
The source directory is determined in the top-level Makefile as ".."
relatively to the "build" directory, but then the kselftest Makefile
switches to "-C ../../.." so "../scripts" then points one level higher
than the source tree e.g. "linux/../scripts" - which fails obviously.
There is no other use-case in the kernel tree where a sub-directory
Makefile tries to call a top-level make target, and it appears this
isn't really a valid thing to do.

selftests/filesystems: add a vfat RENAME_EXCHANGE test
Add a test for the renameat2 RENAME_EXCHANGE support in vfat, but split it in a tool that just does the rename exchange and a script that is run by the kselftests framework on `make TARGETS="filesystems/fat" kselftest`. That way the script can be easily extended to test other file operations. The script creates a 1 MiB disk image, that is then formated with a vfat filesystem and mounted using a loop device. That way all file operations are done on an ephemeral filesystem.

In kselftest framework, all tests can be build/run at a time, and a sub test also can be build/run individually. As follows: $ make kselftest-all TARGETS=resctrl $ make -C tools/testing/selftests run_tests $ make -C tools/testing/selftests TARGETS=resctrl run_tests However, resctrl_tests cannot be run using kselftest framework, users have to change directory to tools/testing/selftests/resctrl/, run "make" to build executable file "resctrl_tests", and run "sudo ./resctrl_tests" to execute the test. To build/run resctrl_tests using kselftest framework. Modify tools/testing/selftests/Makefile and tools/testing/selftests/resctrl/Makefile. Even after this change, users can still build/run resctrl_tests without using framework as before.

selftests: Use -isystem instead of -I to include headers
Selftests need kernel headers and glibc for compilation. In compilation of selftests, uapi headers from kernel source are used instead of default ones while glibc has already been compiled with different header files installed in the operating system. So there can be redefination warnings from compiler. These warnings can be suppressed by using -isystem to include the uapi headers.

kselftest: alsa: Add simplistic test for ALSA mixer controls kselftest
Add a basic test for the mixer control interface. For every control on every sound card in the system it checks that it can read and write the default value where the control supports that and for writeable controls attempts to write all valid values, restoring the default values after each test to minimise disruption for users. There are quite a few areas for improvement - currently no coverage of the generation of notifications, several of the control types don't have any coverage for the values and we don't have any testing of error handling when we attempt to write out of range values - but this provides some basic coverage. This is added as a kselftest since unlike other ALSA test programs it does not require either physical setup of the device or interactive monitoring by users and kselftest is one of the test suites that is frequently run by people doing general automated testing so should increase coverage. It is written in terms of alsa-lib since tinyalsa is not generally packaged for distributions which makes things harder for general users interested in kselftest as a whole but it will be a barrier to people with Android.

af_unix: Add OOB support
This patch adds OOB support for AF_UNIX sockets. The semantics is same as TCP. The last byte of a message with the OOB flag is treated as the OOB byte. The byte is separated into a skb and a pointer to the skb is stored in unix_sock. The pointer is used to enforce OOB semantics.

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.

tests: add mount_setattr() selftests
Add a range of selftests for the new mount_setattr() syscall to verify that it works as expected. This tests that: - no invalid flags can be specified - changing properties of a single mount works and leaves other mounts in the mount tree unchanged - changing a mount tre to read-only when one of the mounts has writers fails and leaves the whole mount tree unchanged - changing mount properties from multiple threads works - changing atime settings works - changing mount propagation works - changing the mount options of a mount tree where the individual mounts in the tree have different mount options only changes the flags that were requested to change - changing mount options from another mount namespace fails - changing mount options from another user namespace fails - idmapped mounts Note, the main test-suite for idmapped mounts is part of xfstests and is pretty huge. These tests here just make sure that the syscalls bits work correctly.

selftests: Skip BPF seftests by default
The BPF selftests have build time dependencies on cutting edge versions of tools in the BPF ecosystem including LLVM which are more involved to satisfy than more typical requirements like installing a package from your distribution. This causes issues for users looking at kselftest in as a whole who find that a default build of kselftest fails and that resolving this is time consuming and adds administrative overhead. The fast pace of BPF development and the need for a full BPF stack to do substantial development or validation work on the code mean that people working directly on it don't see a reasonable way to keep supporting older environments without causing problems with the usability of the BPF tests in BPF development so these requirements are unlikely to be relaxed in the immediate future. There is already support for skipping targets so in order to reduce the barrier to entry for people interested in kselftest as a whole let's use that to skip the BPF tests by default when people work with the top level kselftest build system. Users can still build the BPF selftests as part of the wider kselftest build by specifying SKIP_TARGETS, including setting an empty SKIP_TARGETS to build everything. They can also continue to build the BPF selftests individually in cases where they are specifically focused on BPF. This isn't ideal since it means people will need to take special steps to build the BPF tests but the dependencies mean that realistically this is already the case to some extent and it makes it easier for people to pick up and work with the other selftests which is hopefully a net win.

Staging / IIO driver patches for 5.11-rc1
Here is the big staging and IIO driver pull request for 5.11-rc1 Lots of different things in here: - loads of driver updates - so many coding style cleanups - new IIO drivers - Android ION code is finally removed from the tree - wimax drivers are moved to staging on their way out of the kernel Nothing really exciting, just the constant grind of kernel development :) All have been in linux-next for a while with no reported issues.

A set of updates for entry/exit handling:
- More generalization of entry/exit functionality
- The consolidation work to reclaim TIF flags on x86 and also for non-x86
specific TIF flags which are solely relevant for syscall related work
and have been moved into their own storage space. The x86 specific part
had to be merged in to avoid a major conflict.
- The TIF_NOTIFY_SIGNAL work which replaces the inefficient signal
delivery mode of task work and results in an impressive performance
improvement for io_uring. The non-x86 consolidation of this is going to
come seperate via Jens.
- The selective syscall redirection facility which provides a clean and
efficient way to support the non-Linux syscalls of WINE by catching them
at syscall entry and redirecting them to the user space emulation. This
can be utilized for other purposes as well and has been designed
carefully to avoid overhead for the regular fastpath. This includes the
core changes and the x86 support code.
- Simplification of the context tracking entry/exit handling for the users
of the generic entry code which guarantee the proper ordering and
protection.
- Preparatory changes to make the generic entry code accomodate S390
specific requirements which are mostly related to their syscall restart
mechanism.
