Network drivers such as igb or igc call eth_get_headlen() to determine the
header length for their to be constructed skbs in receive path.
When running HSR on top of these drivers, it results in triggering BUG_ON() in
skb_pull(). The reason is the skb headlen is not sufficient for HSR to work
correctly. skb_pull() notices that.
For instance, eth_get_headlen() returns 14 bytes for TCP traffic over HSR which
is not correct. The problem is, the flow dissection code does not take HSR into
account. Therefore, add support for it.

Currently we do not distinguish between algorithms that fail on
the self-test vs. those which are disabled in FIPS mode (not allowed).
Both are marked as having failed the self-test.
Recently the need arose to allow the usage of certain algorithms only
as arguments to specific template instantiations in FIPS mode. For
example, standalone "dh" must be blocked, but e.g. "ffdhe2048(dh)" is
allowed. Other potential use cases include "cbcmac(aes)", which must
only be used with ccm(), or "ghash", which must be used only for
gcm().
This patch allows this scenario by adding a new flag FIPS_INTERNAL to
indicate those algorithms that are not FIPS-allowed. They can then be
used as template arguments only, i.e. when looked up via
crypto_grab_spawn() to be more specific. The FIPS_INTERNAL bit gets
propagated upwards recursively into the surrounding template
instances, until the construction eventually matches an explicit
testmgr entry with ->fips_allowed being set, if any.
The behaviour to skip !->fips_allowed self-test executions in FIPS
mode will be retained. Note that this effectively means that
FIPS_INTERNAL algorithms are handled very similarly to the INTERNAL
ones in this regard. It is expected that the FIPS_INTERNAL algorithms
will receive sufficient testing when the larger constructions they're
a part of, if any, get exercised by testmgr.
Note that as a side-effect of this patch algorithms which are not
FIPS-allowed will now return ENOENT instead of ELIBBAD. Hopefully
this is not an issue as some people were relying on this already.

Avoid clearing the entire readdir page cache if we're just doing forced
readdirplus for the 'ls -l' heuristic.
Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
|
|
Instead of using a linear index to address the pages, use the cookie of
the first entry, since that is what we use to match the page anyway.
This allows us to avoid re-reading the entire cache on a seekdir() type
of operation. The latter is very common when re-exporting NFS, and is a
major performance drain.
The change does affect our duplicate cookie detection, since we can no
longer rely on the page index as a linear offset for detecting whether
we looped backwards. However since we no longer do a linear search
through all the pages on each call to nfs_readdir(), this is less of a
concern than it was previously.
The other downside is that invalidate_mapping_pages() no longer can use
the page index to avoid clearing pages that have been read. A subsequent
patch will restore the functionality this provides to the 'ls -l'
heuristic.

The heuristic for readdirplus is designed to try to detect 'ls -l' and
similar patterns. It does so by looking for cache hit/miss patterns in
both the attribute cache and in the dcache of the files in a given
directory, and then sets a flag for the readdirplus code to interpret.
The problem with this approach is that a single attribute or dcache miss
can cause the NFS code to force a refresh of the attributes for the
entire set of files contained in the directory.
To be able to make a more nuanced decision, let's sample the number of
hits and misses in the set of open directory descriptors. That allows us
to set thresholds at which we start preferring READDIRPLUS over regular
READDIR, or at which we start to force a re-read of the remaining
readdir cache using READDIRPLUS.

The current NFS readdir code will always try to maximise the amount of
readahead it performs on the assumption that we can cache anything that
isn't immediately read by the process.
There are several cases where this assumption breaks down, including
when the 'ls -l' heuristic kicks in to try to force use of readdirplus
as a batch replacement for lookup/getattr.
This patch therefore tries to tone down the amount of readahead we
perform, and adjust it to try to match the amount of data being
requested by user space.

If the page cache entry that was last read gets invalidated for some
reason, then make sure we can re-create it on the next call to readdir.
This, combined with the cache page validation, allows us to reuse the
cached value of page-index on successive calls to nfs_readdir.
Credit is due to Benjamin Coddington for showing that the concept works,
and that it allows for improved cache sharing between processes even in
the case where pages are lost due to LRU or active invalidation.

Qualcomm driver updates for v5.18
This refactors the Qualcomm mdt file loader, to partially decouple it
from the SCM peripheral-authentication-service. This is needed as newer
platforms, such as the Qualcomm SM8450, require the metadata to remain
accessible to TrustZone during a longer time. This is followed by the
introduction of remoteproc drivers for SM8450 (Snapdragon 8 Gen 1).
It changes the way hardware version differences are handled in the LLCC
driver and introduces support for Qualcomm SM8450. While updating the dt
binding for LLCC it also introduces the missing SM8350 compatible.
The ocmem and aoss drivers gains missing put_device() calls and rpmpd
gains a missing check for kcalloc() failure.
The SPM driver is updated to avoid instantiating the SPM cpuidle devices
if the CPUs aren't controlled by SPM, such as when Snapdragon 8916
operates in 32-bit mode without PSCI.
The RPM power-domain driver gains MSM8226 support.
Lastly the socinfo driver gains knowledge about a few new SoCs and
PMICs.

Problem:
Some directory vxattrs (e.g. ceph.dir.pin.random) are governed by
information that isn't necessarily shared with the client. Add support
for the new GETVXATTR operation, which allows the client to query the
MDS directly for vxattrs.
When the client is queried for a vxattr that doesn't have a special
handler, have it issue a GETVXATTR to the MDS directly.
Solution:
Adds new getvxattr op to fetch ceph.dir.pin*, ceph.dir.layout* and
ceph.file.layout* vxattrs.
If the entire layout for a dir or a file is being set, then it is
expected that the layout be set in standard JSON format. Individual
field value retrieval is not wrapped in JSON. The JSON format also
applies while setting the vxattr if the entire layout is being set in
one go.
As a temporary measure, setting a vxattr can also be done in the old
format. The old format will be deprecated in the future.

TASK_RTLOCK_WAIT currently isn't part of TASK_REPORT, thus a task blocking
on an rtlock will appear as having a task state == 0, IOW TASK_RUNNING.
The actual state is saved in p->saved_state, but reading it after reading
p->__state has a few issues:
o that could still be TASK_RUNNING in the case of e.g. rt_spin_lock
o ttwu_state_match() might have changed that to TASK_RUNNING
As pointed out by Eric, adding TASK_RTLOCK_WAIT to TASK_REPORT implies
exposing a new state to userspace tools which way not know what to do with
them. The only information that needs to be conveyed here is that a task is
waiting on an rt_mutex, which matches TASK_UNINTERRUPTIBLE - there's no
need for a new state.

As of commit
c6e7bd7afaeb ("sched/core: Optimize ttwu() spinning on p->on_cpu")
the following sequence becomes possible:
p->__state = TASK_INTERRUPTIBLE;
__schedule()
deactivate_task(p);
ttwu()

p->__state=TASK_WAKING
trace_sched_switch()
__trace_sched_switch_state()

return 0;
TASK_WAKING isn't in TASK_REPORT, so the task appears as TASK_RUNNING in
the trace event.
Prevent this by pushing the value read from __schedule() down the trace
event.

HID_QUIRK_INVERT is kind of complex to deal with and was bogus.
Furthermore, it didn't make sense to use a global per struct hid_device
quirk for something dynamic as the current state.
Store the current tool information in the report itself, and re-order
the processing of the fields to enforce having all the tablet "state"
fields before getting to In Range and other input fields.
This way, we now have all the information whether a tool is present
or not while processing In Range.
This new behavior enforces that only one tool gets forwarded to userspace
at the same time, and that if either eraser or invert is set, we enforce
BTN_TOOL_RUBBER.
Note that the release of the previous tool now happens in its own EV_SYN
report so userspace doesn't get confused by having 2 tools.
These changes are tested in the following hid-tools regression tests:

When a device exposes both Invert and InRange, Invert must be processed
before InRange. If we keep the order of the device and we process them
out of order, InRange will first set BTN_TOOL_PEN, and then Invert will
set BTN_TOOL_RUBBER. Userspace knows how to deal with that situation,
but fixing it in the kernel is now easier.

This will be used in a later commit:
we build a list of input fields (and usage_index) that is ordered based
on a usage priority.
Changing the usage priority allows to re-order the processed list, meaning
that we can enforce some usages to be process before others.
For instance, before processing InRange in the HID tablets, we need to
know if we are using the eraser (side or button). Enforcing a higher
(lower number) priority for Invert allows to force the input stack to
process that field before.

Remove the generic kvm_reload_remote_mmus() and open code its
functionality into the two x86 callers. x86 is (obviously) the only
architecture that uses the hook, and is also the only architecture that
uses KVM_REQ_MMU_RELOAD in a way that's consistent with the name. That
will change in a future patch, as x86's usage when zapping a single
shadow page x86 doesn't actually _need_ to reload all vCPUs' MMUs, only
MMUs whose root is being zapped actually need to be reloaded.
s390 also uses KVM_REQ_MMU_RELOAD, but for a slightly different purpose.
Drop the generic code in anticipation of implementing s390 and x86 arch
specific requests, which will allow dropping KVM_REQ_MMU_RELOAD entirely.
Opportunistically reword the x86 TDP MMU comment to avoid making
references to functions (and requests!) when possible, and to remove the
rather ambiguous "this".

Add a new helper function to copy absinfo from one input_dev to
another input_dev.
This is useful to e.g. setup a pen/stylus input-device for combined
touchscreen/pen hardware where the pen uses the same coordinates as
the touchscreen.

MT8192 contains an experimental Accelerator Coherency Port
implementation, which does not work correctly but was unintentionally
enabled by default. For correct operation of the GPU, we must set a
chicken bit disabling ACP on MT8192.
Adapted from the following downstream change to the out-of-tree, legacy
Mali GPU driver:
https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/2781271/5
Note this change is required for both Panfrost and the legacy kernel
driver.

====================
mlx5-next 2022-22-02
The following PR includes updates to mlx5-next branch:
Headlines:
==========
1) Jakub cleans up unused static inline functions
2) I did some low level firmware command interface return status changes to
provide the caller with full visibility on the error/status returned by
the Firmware.
3) Use the new command interface in RDMA DEVX usecases to avoid flooding
dmesg with some "expected" user error prone use cases.
4) Moshe also uses the new command interface to grab the specific error
code from MFRL register command to provide the exact error reason for
why SW reset couldn't perform internally in FW.
5) From Mark Bloch: Lag, drop packets in hardware when possible
In active-backup mode the inactive interface's packets are dropped by the
bond device. In switchdev where TC rules are offloaded to the FDB
this can lead to packets being hit in the FDB where without offload
they would have been dropped before reaching TC rules in the kernel.
Create a drop rule to make sure packets on inactive ports are dropped
before reaching the FDB.
Listen on NETDEV_CHANGEUPPER / NETDEV_CHANGEINFODATA events and record
the inactive state and offload accordingly.
* 'mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux:

Netfilter assumes its called with rcu_read_lock held, but in egress
hook case it may be called with BH readlock.
This triggers lockdep splat.
In order to avoid to change all rcu_dereference() to
rcu_dereference_check(..., rcu_read_lock_bh_held()), wrap nf_hook_slow
with read lock/unlock pair.

Define a generic UART_LCR_WLEN() macro with a size argument. It can be
used to encode byte size into an LCR value. Therefore we can use it to
simplify the drivers using tty_get_char_size() in the next patches.

spi: Make remove() return void
This series from Uwe Kleine-König converts the spi remove function to
return void since there is nothing useful that we can do with a failure
and it as more buses are converted it'll enable further work on the
driver core.

Initial support for the RPC_AUTH_TLS authentication flavor enables
NFSD to eventually accept an RPC_AUTH_TLS probe from clients. This
patch simply prevents NFSD from rejecting these probes completely.
In the meantime, graft this support in now so that RPC_AUTH_TLS
support keeps up with generic code and API changes in the RPC
server.
Down the road, server-side transport implementations will populate
xpo_start_tls when they can support RPC-with-TLS. For example, TCP
will eventually populate it, but RDMA won't.

A random sample of kthread_create() callers shows sunrpc is the only
