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.

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"

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull force_sig() argument change from Eric Biederman:
"A source of error over the years has been that force_sig has taken a
task parameter when it is only safe to use force_sig with the current
task.
The force_sig function is built for delivering synchronous signals
such as SIGSEGV where the userspace application caused a synchronous
fault (such as a page fault) and the kernel responded with a signal.
Because the name force_sig does not make this clear, and because the
force_sig takes a task parameter the function force_sig has been
abused for sending other kinds of signals over the years. Slowly those
have been fixed when the oopses have been tracked down.
This set of changes fixes the remaining abusers of force_sig and
carefully rips out the task parameter from force_sig and friends
making this kind of error almost impossible in the future"

The pstore_mkfile() function is passed a pointer to a struct
pstore_record. On success it consumes this 'record' pointer and
references it from the created inode.
On failure, however, it may or may not free the record. There are even
two different code paths which return -ENOMEM -- one of which does and
the other doesn't free the record.
Make the behaviour deterministic by never consuming and freeing the
record when returning failure, allowing the caller to do the cleanup
consistently.

When you try to run an upstream kernel on an old ARM-based Chromebook
you'll find that console-ramoops doesn't work.
Old ARM-based Chromebooks, before <https://crrev.com/c/439792>
("ramoops: support upstream {console,pmsg,ftrace}-size properties")
used to create a "ramoops" node at the top level that looked like:
/ {
ramoops {
compatible = "ramoops";
reg = <...>;
record-size = <...>;
dump-oops;
};
};
...and these Chromebooks assumed that the downstream kernel would make
console_size / pmsg_size match the record size. The above ramoops
node was added by the firmware so it's not easy to make any changes.
Let's match the expected behavior, but only for those using the old
backward-compatible way of working where ramoops is right under the
root node.
NOTE: if there are some out-of-tree devices that had ramoops at the
top level, left everything but the record size as 0, and somehow
doesn't want this behavior, we can try to add more conditions here.

nfp: tls: fixes for initial TLS support
This series brings various fixes to nfp tls offload recently added
to net-next.
First 4 patches revolve around device mailbox communication, trying
to make it more reliable. Next patch fixes statistical counter.
Patch 6 improves the TX resync if device communication failed.
Patch 7 makes sure we remove keys from memory after talking to FW.
Patch 8 adds missing tls context initialization, we fill in the
context information from various places based on the configuration
and looks like we missed the init in the case of where TX is
offloaded, but RX wasn't initialized yet. Patches 9 and 10 make
the nfp driver undo TLS state changes if we need to drop the
frame (e.g. due to DMA mapping error).
Last but not least TLS fallback should not adjust socket memory
after skb_orphan_partial(). This code will go away once we forbid
orphaning of skbs in need of crypto, but that's "real" -next
material, so lets do a quick fix.

netem runs skb_orphan_partial() which "disconnects" the skb
from normal TCP write memory accounting. We should not adjust

Turns out TLS_TX in HW offload mode does not initialize tls_prot_info.
Since commit 9cd81988cce1 ("net/tls: use version from prot") we actually
use this field on the datapath. Luckily we always compare it to TLS 1.3,
and assume 1.2 otherwise. So since zero is not equal to 1.3, everything
worked fine.

Introduce a return code for the tls_dev_resync callback.
When the driver TX resync fails, kernel can retry the resync again
until it succeeds. This prevents drivers from attempting to offload
TLS packets if the connection is known to be out of sync.
We don't worry about the RX resync since they will be retried naturally
as more encrypted records get received.

Increase the batch limit to consume small message bursts more
effectively. Practically, the effect on the 'add' messages is not
significant since the mailbox is sized such that the 'add' messages are
still limited to the same order of magnitude that it was originally set
for.
Furthermore, increase the queue size limit to 1024 entries. This further
improves the handling of bursts of small control messages.

Connection 4 tuple reuse is slightly problematic - TLS socket
and context do not get destroyed until all the associated skbs
left the system and all references are released. This leads
to stale connection entry in the device preventing addition
of new one if the 4 tuple is reused quickly enough.
Instead of using read 4 tuple as the key use a unique ID.
Set the protocol to TCP and port to 0 to ensure no collisions
with real connections.

Pull keyring ACL support from David Howells:
"This changes the permissions model used by keys and keyrings to be
based on an internal ACL by the following means:
- Replace the permissions mask internally with an ACL that contains a
list of ACEs, each with a specific subject with a permissions mask.
Potted default ACLs are available for new keys and keyrings.
ACE subjects can be macroised to indicate the UID and GID specified
on the key (which remain). Future commits will be able to add
additional subject types, such as specific UIDs or domain
tags/namespaces.
Also split a number of permissions to give finer control. Examples
include splitting the revocation permit from the change-attributes
permit, thereby allowing someone to be granted permission to revoke
a key without allowing them to change the owner; also the ability
to join a keyring is split from the ability to link to it, thereby
stopping a process accessing a keyring by joining it and thus
acquiring use of possessor permits.
- Provide a keyctl to allow the granting or denial of one or more
permits to a specific subject. Direct access to the ACL is not
granted, and the ACL cannot be viewed"

Currently, TC offers the ability to match on the MPLS fields of a packet
through the use of the flow_dissector_key_mpls struct. However, as yet, TC
actions do not allow the modification or manipulation of such fields.
Add a new module that registers TC action ops to allow manipulation of
MPLS. This includes the ability to push and pop headers as well as modify
the contents of new or existing headers. A further action to decrement the
TTL field of an MPLS header is also provided with a new helper added to
support this.
Examples of the usage of the new action with flower rules to push and pop
MPLS labels are:
tc filter add dev eth0 protocol ip parent ffff: flower \
action mpls push protocol mpls_uc label 123 \
action mirred egress redirect dev eth1
tc filter add dev eth0 protocol mpls_uc parent ffff: flower \
action mpls pop protocol ipv4 \
action mirred egress redirect dev eth1
