MacOS and Win11 support AES256 encrytion and it is included in the cipher
array of encryption context. Especially on macOS, The most preferred
cipher is AES256. Connecting to ksmbd fails on newer MacOS clients that
support AES256 encryption. MacOS send disconnect request after receiving
final session setup response from ksmbd. Because final session setup is
signed with signing key was generated incorrectly.
For signging key, 'L' value should be initialized to 128 if key size is
16bytes.

My diagnosis is that the memcpy() at the end of gss_krb5_checksum()
reads past the end of the buffer containing the checksum data
because the callers have ignored gss_krb5_checksum()'s API contract:
* Caller provides the truncation length of the output token (h) in
* cksumout.len.
Instead they provide the fixed length of the hmac buffer. This
length happens to be larger than the value returned by
crypto_ahash_digestsize().
Change these errant callers to work like krb5_etm_{en,de}crypt().
As a defensive measure, bound the length of the byte copy at the
end of gss_krb5_checksum().

Commit 7c3d5c20dc16 ("thermal/core: Add a generic thermal_zone_get_trip()
function") stopped marking trip points with a zero temperature as
disabled, behavior that was originally introduced in commit 81ad4276b505
("Thermal: Ignore invalid trip points").
When using the mlxsw driver we see that when such trip points are not
disabled, the thermal subsystem repeatedly tries to set the state of the
associated cooling devices to the maximum state.
Address this by restoring the original behavior and mark trip points
with a zero temperature as disabled.

__copy_xstate_to_uabi_buf() copies either from the tasks XSAVE buffer
or from init_fpstate into the ptrace buffer. Dynamic features, like
XTILEDATA, have an all zeroes init state and are not saved in
init_fpstate, which means the corresponding bit is not set in the
xfeatures bitmap of the init_fpstate header.
But __copy_xstate_to_uabi_buf() retrieves addresses for both the tasks
xstate and init_fpstate unconditionally via __raw_xsave_addr().
So if the tasks XSAVE buffer has a dynamic feature set, then the
address retrieval for init_fpstate triggers the warning in
__raw_xsave_addr() which checks the feature bit in the init_fpstate
header.
Remove the address retrieval from init_fpstate for extended features.
They have an all zeroes init state so init_fpstate has zeros for them.
Then zeroing the user buffer for the init state is the same as copying
them from init_fpstate.

The commit 97e3d26b5e5f ("x86/mm: Randomize per-cpu entry area") fixed
an omission of KASLR on CPU entry areas. It doesn't take into account
KASLR switches though, which may result in unintended non-determinism
when a user wants to avoid it (e.g. debugging, benchmarking).
Generate only a single combination of CPU entry areas offsets -- the
linear array that existed prior randomization when KASLR is turned off.
Since we have 3f148f331814 ("x86/kasan: Map shadow for percpu pages on
demand") and followups, we can use the more relaxed guard
kasrl_enabled() (in contrast to kaslr_memory_enabled()).

When driver doesn't implement a bpf_xdp_metadata kfunc the fallback
implementation returns EOPNOTSUPP, which indicate device driver doesn't
implement this kfunc.
Currently many drivers also return EOPNOTSUPP when the hint isn't
available, which is ambiguous from an API point of view. Instead
change drivers to return ENODATA in these cases.
There can be natural cases why a driver doesn't provide any hardware
info for a specific hint, even on a frame to frame basis (e.g. PTP).
Lets keep these cases as separate return codes.
When describing the return values, adjust the function kernel-doc layout
to get proper rendering for the return values.

The hvc machinery registers both a console and a tty device based on
the hv ops provided by the specific implementation. Those two
interfaces however have different locks, and there's no single locks
that's shared between the tty and the console implementations, hence
the driver needs to protect itself against concurrent accesses.
Otherwise concurrent calls using the split interfaces are likely to
corrupt the ring indexes, leaving the console unusable.
Introduce a lock to xencons_info to serialize accesses to the shared
ring. This is only required when using the shared memory console,
concurrent accesses to the hypercall based console implementation are
not an issue.
Note the conditional logic in domU_read_console() is slightly modified
so the notify_daemon() call can be done outside of the locked region:
it's an hypercall and there's no need for it to be done with the lock
held.

The continuous read support added recently makes nandsim
unhappy. Indeed, all the supported commands should be re-encoded into
internal commands, so of course there is currently no support for the
commands and patterns needed for continuous reads to work.
I tried to add support for them but nandsim (which is more a tool to
develop/debug upper layers rather than the raw NAND core) suffers from a
big limitation: it's internal parser needs to know what exact operation
is happening when the address cycles are performed. The research is then
sequential from the start up to the address cycles, but does not check
what's coming next even though the information is available. This is a
limitation which is related to the old API used by the core which kind
of forced the controllers to guess what operation was being performed
rather early. Today the core uses a more transparent API called
->exec_op() which no longer requires controller drivers to do any more
guessing, but despite being updated to ->exec_op(), nandsim is still a
bit constrained on this regard and thus cannot handle sequential page
reads because the start sequence beginning is identical to a regular
page read.
If the internal algorithm is updated some day, it should be possible to
make it support sequential page reads by adding something like:
/* Large page devices continuous read page start */
{OPT_LARGEPAGE, {STATE_CMD_READ0, STATE_ADDR_PAGE, STATE_CMD_READSTART,
STATE_CMD_READCACHESEQ | ACTION_CPY, STATE_DATAOUT,
STATE_READY}},
/* Large page devices continuous read page continue */
{OPT_LARGEPAGE, {STATE_CMD_READCACHESEQ | ACTION_CPY_NEXT, STATE_DATAOUT,
STATE_READY}},
/* Large page devices continuous read page end */
{OPT_LARGEPAGE, {STATE_CMD_READCACHEEND | ACTION_CPY_NEXT, STATE_DATAOUT,
STATE_READY}},
For now, we just return -EOPNOTSUPP when the core asks controller
drivers if they support the feature in order to prevent any further use
of these opcodes.
Note: This is a hack, ->exec_op() is not supposed to check against the
COMMAND opcodes unless _really_ needed.

When a cpufreq policy appears or goes away, the CPU cooling devices for
the CPUs covered by that policy need to be updated so that the new
processor_get_max_state() value is stored as max_state and the
statistics in sysfs are rearranged for each of them.
Do that accordingly in acpi_thermal_cpufreq_init() and
acpi_thermal_cpufreq_exit().

Introduce a core thermal API function, thermal_cooling_device_update(),
for updating the max_state value for a cooling device and rearranging
its statistics in sysfs after a possible change of its ->get_max_state()
callback return value.
That callback is now invoked only once, during cooling device
registration, to populate the max_state field in the cooling device
object, so if its return value changes, it needs to be invoked again
and the new return value needs to be stored as max_state. Moreover,
the statistics presented in sysfs need to be rearranged in general,
because there may not be enough room in them to store data for all
of the possible states (in the case when max_state grows).
The new function takes care of that (and some other minor things
related to it), but some extra locking and lockdep annotations are
added in several places too to protect against crashes in the cases
when the statistics are not present or when a stale max_state value
might be used by sysfs attributes.
Note that the actual user of the new function will be added separately.

The cpufreq policy notifier in the ACPI processor driver may as
well be registered before the driver itself, which causes
acpi_processor_cpufreq_init to be true (unless the notifier
registration fails, which is unlikely at that point) when the
ACPI CPU thermal cooling devices are registered, so the
processor_get_max_state() result does not change while
acpi_processor_driver_init() is running.
Change the ordering in acpi_processor_driver_init() accordingly
to prevent the max_state value from remaining 0 permanently for all
ACPI CPU cooling devices due to setting acpi_processor_cpufreq_init
too late. [Note that processor_get_max_state() may still return
different values at different times after this change, depending on
the cpufreq driver registration time, but that issue needs to be
addressed separately.]

The s390 DMA API conversion changes currently under review will extend
the use of the s390-iommu driver to the DMA API. With s390's mandatory
use of an IOMMU this means all DMA for PCI devices will then use the
s390-iommu driver. With this in mind and considering my involvement in
these changes it makes sense to reflect this increased interdependence
in the maintainer structure. Thus add myself as first maintainer and
move Gerald to reviewer status.

Explicit alignment and page alignment are used only to calculate
the stride, not when checking actual slot physical address.
Originally, only page alignment was implemented, and that worked,
because the whole SWIOTLB is allocated on a page boundary, so
aligning the start index was sufficient to ensure a page-aligned
slot.
When commit 1f221a0d0dbf ("swiotlb: respect min_align_mask") added
support for min_align_mask, the index could be incremented in the
search loop, potentially finding an unaligned slot if minimum device
alignment is between IO_TLB_SIZE and PAGE_SIZE. The bug could go
unnoticed, because the slot size is 2 KiB, and the most common page
size is 4 KiB, so there is no alignment value in between.
IIUC the intention has been to find a slot that conforms to all
alignment constraints: device minimum alignment, an explicit
alignment (given as function parameter) and optionally page
alignment (if allocation size is >= PAGE_SIZE). The most
restrictive mask can be trivially computed with logical AND. The
rest can stay.

Vladimir Oltean says:
====================
Fix trainwreck with Ocelot switch statistics counters
While testing the patch set for preemptible traffic classes with some
controlled traffic and measuring counter deltas:
https://lore.kernel.org/netdev/20230220122343.1156614-1-vladimir.oltean@nxp.com/
I noticed that in the output of "ethtool -S swp0 --groups eth-mac
eth-phy eth-ctrl rmon -- --src emac | grep -v ': 0'", the TX counters
were off. Quickly I realized that their values were permutated by 1
compared to their names, and that for example
tx-rmon-etherStatsPkts64to64Octets was incrementing when
tx-rmon-etherStatsPkts65to127Octets should have.
Initially I suspected something having to do with the bulk reading
logic, and indeed I found a bug there (fixed as 1/3), but that was not
the source of the problems. Instead it revealed other problems.
While dumping the regions created by the driver on my switch, I figured
out that it sees a discontinuity which shouldn't have existed between
reg 0x278 and reg 0x280.
Discontinuity between last reg 0x0 and new reg 0x0, creating new region
Discontinuity between last reg 0x108 and new reg 0x200, creating new region
Discontinuity between last reg 0x278 and new reg 0x280, creating new region
Discontinuity between last reg 0x2b0 and new reg 0x400, creating new region
region of 67 contiguous counters starting with SYS:STAT:CNT[0x000]
region of 31 contiguous counters starting with SYS:STAT:CNT[0x080]
region of 13 contiguous counters starting with SYS:STAT:CNT[0x0a0]
region of 18 contiguous counters starting with SYS:STAT:CNT[0x100]
That is where TX_MM_HOLD should have been, and that was the bug, since
it was missing. After adding it, the regions look like this and the
off-by-one issue is resolved:
Discontinuity between last reg 0x000000 and new reg 0x000000, creating new region
Discontinuity between last reg 0x000108 and new reg 0x000200, creating new region
Discontinuity between last reg 0x0002b0 and new reg 0x000400, creating new region
region of 67 contiguous counters starting with SYS:STAT:CNT[0x000]
region of 45 contiguous counters starting with SYS:STAT:CNT[0x080]
region of 18 contiguous counters starting with SYS:STAT:CNT[0x100]
However, as I am thinking out loud, it should have not reported the
other counters as off by one even when skipping TX_MM_HOLD... after all,
on Ocelot/Seville, there are more counters which need to be skipped.
Which is when I investigated and noticed the bug solved in 2/3.
I've validated that both on native VSC9959 (which uses
ocelot_mm_stats_layout) as well as by faking the other switches by
making VSC9959 use the plain ocelot_stats_layout.
To summarize: on all Ocelot switches, the TX counters and drop counters
are completely broken. The RX counters are mostly fine.
With this occasion, I have collected more cleanup patches in this area,
which I'm going to submit after the net -> net-next merge.
