Pull clone3 system call from Christian Brauner:
"This adds the clone3 syscall which is an extensible successor to clone
after we snagged the last flag with CLONE_PIDFD during the 5.2 merge
window for clone(). It cleanly supports all of the flags from clone()
and thus all legacy workloads.
There are few user visible differences between clone3 and clone.
First, CLONE_DETACHED will cause EINVAL with clone3 so we can reuse
this flag. Second, the CSIGNAL flag is deprecated and will cause
EINVAL to be reported. It is superseeded by a dedicated "exit_signal"
argument in struct clone_args thus freeing up even more flags. And
third, clone3 gives CLONE_PIDFD a dedicated return argument in struct
clone_args instead of abusing CLONE_PARENT_SETTID's parent_tidptr
argument.
The clone3 uapi is designed to be easy to handle on 32- and 64 bit:
/* uapi */
struct clone_args {
__aligned_u64 flags;
__aligned_u64 pidfd;
__aligned_u64 child_tid;
__aligned_u64 parent_tid;
__aligned_u64 exit_signal;
__aligned_u64 stack;
__aligned_u64 stack_size;
__aligned_u64 tls;
};
and a separate kernel struct is used that uses proper kernel typing:
/* kernel internal */
struct kernel_clone_args {
u64 flags;
int __user *pidfd;
int __user *child_tid;
int __user *parent_tid;
int exit_signal;
unsigned long stack;
unsigned long stack_size;
unsigned long tls;
};
The system call comes with a size argument which enables the kernel to
detect what version of clone_args userspace is passing in. clone3
validates that any additional bytes a given kernel does not know about
are set to zero and that the size never exceeds a page.
A nice feature is that this patchset allowed us to cleanup and
simplify various core kernel codepaths in kernel/fork.c by making the
internal _do_fork() function take struct kernel_clone_args even for
legacy clone().
This patch also unblocks the time namespace patchset which wants to
introduce a new CLONE_TIMENS flag.
Note, that clone3 has only been wired up for x86{_32,64}, arm{64}, and
xtensa. These were the architectures that did not require special
massaging.
Other architectures treat fork-like system calls individually and
after some back and forth neither Arnd nor I felt confident that we
dared to add clone3 unconditionally to all architectures. We agreed to
leave this up to individual architecture maintainers. This is why
there's an additional patch that introduces __ARCH_WANT_SYS_CLONE3
which any architecture can set once it has implemented support for
clone3. The patch also adds a cond_syscall(clone3) for architectures
such as nios2 or h8300 that generate their syscall table by simply
including asm-generic/unistd.h. The hope is to get rid of
__ARCH_WANT_SYS_CLONE3 and cond_syscall() rather soon"

Pull pidfd updates from Christian Brauner:
"This adds two main features.
- First, it adds polling support for pidfds. This allows process
managers to know when a (non-parent) process dies in a race-free
way.
The notification mechanism used follows the same logic that is
currently used when the parent of a task is notified of a child's
death. With this patchset it is possible to put pidfds in an
{e}poll loop and get reliable notifications for process (i.e.
thread-group) exit.
- The second feature compliments the first one by making it possible
to retrieve pollable pidfds for processes that were not created
using CLONE_PIDFD.
A lot of processes get created with traditional PID-based calls
such as fork() or clone() (without CLONE_PIDFD). For these
processes a caller can currently not create a pollable pidfd. This
is a problem for Android's low memory killer (LMK) and service
managers such as systemd.
Both patchsets are accompanied by selftests.
It's perhaps worth noting that the work done so far and the work done
in this branch for pidfd_open() and polling support do already see
some adoption:
- Android is in the process of backporting this work to all their LTS
kernels [1]
- Service managers make use of pidfd_send_signal but will need to
wait until we enable waiting on pidfds for full adoption.
- And projects I maintain make use of both pidfd_send_signal and
CLONE_PIDFD [2] and will use polling support and pidfd_open() too"

Pull nfsd updates from Bruce Fields:
"Highlights:
- Add a new /proc/fs/nfsd/clients/ directory which exposes some
long-requested information about NFSv4 clients (like open files)
and allows forced revocation of client state.
- Replace the global duplicate reply cache by a cache per network
namespace; previously, a request in one network namespace could
incorrectly match an entry from another, though we haven't seen
this in production. This is the last remaining container bug that
I'm aware of; at this point you should be able to run separate
nfsd's in each network namespace, each with their own set of
exports, and everything should work.
- Cleanup and modify lock code to show the pid of lockd as the owner
of NLM locks. This is the correct version of the bugfix originally
attempted in b8eee0e90f97 ("lockd: Show pid of lockd for remote
locks")"

Pull copy_file_range updates from Darrick Wong:
"This fixes numerous parameter checking problems and inconsistent
behaviors in the new(ish) copy_file_range system call.
Now the system call will actually check its range parameters
correctly; refuse to copy into files for which the caller does not
have sufficient privileges; update mtime and strip setuid like file
writes are supposed to do; and allows copying up to the EOF of the
source file instead of failing the call like we used to.
Summary:
- Create a generic copy_file_range handler and make individual
filesystems responsible for calling it (i.e. no more assuming that
do_splice_direct will work or is appropriate)
- Refactor copy_file_range and remap_range parameter checking where
they are the same
- Install missing copy_file_range parameter checking(!)
- Remove suid/sgid and update mtime like any other file write
- Change the behavior so that a copy range crossing the source file's
eof will result in a short copy to the source file's eof instead of
EINVAL
- Permit filesystems to decide if they want to handle
cross-superblock copy_file_range in their local handlers"

7a1ade847596 ("keys: Provide KEYCTL_GRANT_PERMISSION")
2e12256b9a76 ("keys: Replace uid/gid/perm permissions checking with an ACL")

It turns out that it breaks booting with an encrypted volume, and Eric

The root cause of all the breakage is likely the same, but David Howells

This patch adds hardware offload support for nftables through the
existing netdev_ops->ndo_setup_tc() interface, the TC_SETUP_CLSFLOWER
classifier and the flow rule API. This hardware offload support is
available for the NFPROTO_NETDEV family and the ingress hook.
Each nftables expression has a new ->offload interface, that is used to
populate the flow rule object that is attached to the transaction
object.
There is a new per-table NFT_TABLE_F_HW flag, that is set on to offload
an entire table, including all of its chains.
This patch supports for basic metadata (layer 3 and 4 protocol numbers),
5-tuple payload matching and the accept/drop actions; this also includes
basechain hardware offload only.

Most drivers do the same thing to set up the flow block callbacks, this
patch adds a helper function to do this.
This preparation patch reduces the number of changes to adapt the
existing drivers to use the flow block callback API.
This new helper function takes a flow block list per-driver, which is
set to NULL until this driver list is used.
This patch also introduces the flow_block_command and
flow_block_binder_type enumerations, which are renamed to use
FLOW_BLOCK_* in follow up patches.
There are three definitions (aliases) in order to reduce the number of
updates in this patch, which go away once drivers are fully adapted to
use this flow block API.

- A fair pile of RST conversions, many from Mauro. These create more
than the usual number of simple but annoying merge conflicts with
other trees, unfortunately. He has a lot more of these waiting on
the wings that, I think, will go to you directly later on.
- A new document on how to use merges and rebases in kernel repos,
and one on Spectre vulnerabilities.
- Various improvements to the build system, including automatic
markup of function() references because some people, for reasons I
will never understand, were of the opinion that
:c:func:``function()`` is unattractive and not fun to type.
- We now recommend using sphinx 1.7, but still support back to 1.4.
- Lots of smaller improvements, warning fixes, typo fixes, etc"

Allow sending a packet to conntrack module for connection tracking.
The packet will be marked with conntrack connection's state, and
any metadata such as conntrack mark and label. This state metadata
can later be matched against with tc classifers, for example with the
flower classifier as below.
In addition to committing new connections the user can optionally
specific a zone to track within, set a mark/label and configure nat
with an address range and port range.
Usage is as follows:
$ tc qdisc add dev ens1f0_0 ingress
$ tc qdisc add dev ens1f0_1 ingress
$ tc filter add dev ens1f0_0 ingress \
prio 1 chain 0 proto ip \
flower ip_proto tcp ct_state -trk \

In an eswitch, PCI VF may have port which is normally represented using
a representor netdevice.
To have better visibility of eswitch port, its association with VF,
and its representor netdevice, introduce a PCI VF port flavour.
When devlink port flavour is PCI VF, fill up PCI VF attributes of
the port.
Extend port name creation using PCI PF and VF number scheme on best
effort basis, so that vendor drivers can skip defining their own scheme.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
- Make the dma-iommu code more generic so that it can be used outside
of the ARM context with other IOMMU drivers. Goal is to make use of
it on x86 too.
- Generic IOMMU domain support for the Intel VT-d driver. This driver
now makes more use of common IOMMU code to allocate default domains
for the devices it handles.
- An IOMMU fault reporting API to userspace. With that the IOMMU fault
handling can be done in user-space, for example to forward the faults
to a VM.
- Better handling for reserved regions requested by the firmware. These
can be 'relaxed' now, meaning that those don't prevent a device being
attached to a VM.
- Suspend/Resume support for the Renesas IOMMU driver.
- Added support for dumping SVA related fields of the DMAR table in the
Intel VT-d driver via debugfs.
- A pile of smaller fixes and cleanups.

- Support for configuring a minimum time for chip select to be
deasserted between transfers from Martin Sperl.
- A rework of the ACPI device instantiation code from Ard Biesheuvel.
- Fairly substantial development on the AT91 USART, BCM2835 and

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the big slew of GPIO changes for the v5.3 kernel cycle. This
is mostly incremental work this time.
Three important things:
- The FMC subsystem is deleted through my tree. This happens through
GPIO as its demise was discussed in relation to a patch decoupling
its GPIO implementation from the standard way of handling GPIO. As
it turns out, that is not the only subsystem it reimplements and
the authors think it is better do scratch it and start over using
the proper kernel subsystems than try to polish the rust shiny. See
the commit (ACKed by the maintainers) for details.
- Arnd made a small devres patch that was ACKed by Greg and goes into
the device core.
- SPDX header change colissions may happen, because at times I've
seen that quite a lot changed during the -rc:s in regards to SPDX.
(It is good stuff, tglx has me convinced, and it is worth the
occasional pain.)
Apart from this is is nothing controversial or problematic.
Summary:
Core:
- When a gpio_chip request GPIOs from itself, it can now fully
control the line characteristics, both machine and consumer flags.
This makes a lot of sense, but took some time before I figured out
that this is how it has to work.
- Several smallish documentation fixes.
New drivers:
- The PCA953x driver now supports the TI TCA9539.
- The DaVinci driver now supports the K3 AM654 SoCs.
Driver improvements:
- Major overhaul and hardening of the OMAP driver by Russell King.
- Starting to move some drivers to the new API passing irq_chip along
with the gpio_chip when adding the gpio_chip instead of adding it
separately.
Unrelated:
- Delete the FMC subsystem"
