Because of .., files outside the share directory
could be accessed. To prevent this, normalize
the given path and remove all . and ..
components.
In addition to the usual large set of regression tests (smbtorture
and xfstests), ran various tests on this to specifically check
path name validation including libsmb2 tests to verify path
normalization:

of_dma_set_restricted_buffer fails to handle negative return values from
of_property_count_elems_of_size, e.g. when the property does not exist.
This results in an attempt to assign a non-existent reserved memory
region to the device and a warning being printed. Fix the condition to
take negative values into account.

already by the platform firmware (Doug Smythies).

Pull io_uring iov_iter retry fixes from Jens Axboe:
"This adds a helper to save/restore iov_iter state, and modifies
io_uring to use it.
After that is done, we can now kill the iter->truncated addition that
we added for this release. The io_uring change is being overly
cautious with the save/restore/advance, but better safe than sorry and
we can always improve that and reduce the overhead if it proves to be
of concern. The only case to be worried about in this regard is huge
IO, where iteration can take a while to iterate segments.
I spent some time writing test cases, and expanded the coverage quite
a bit from the last posting of this. liburing carries this regression
test case now:
https://git.kernel.dk/cgit/liburing/tree/test/file-verify.c
which exercises all of this. It now also supports provided buffers,
and explicitly tests for end-of-file/device truncation as well.
On top of that, Pavel sanitized the IOPOLL retry path to follow the
exact same pattern as normal IO"

Pull io_uring fixes from Jens Axboe:
"Mostly fixes for regressions in this cycle, but also a few fixes that

The odd one out is a tweak to the direct files added in this release,

explicit removal of that slot first. It's a considerable improvement
in usability to that API, hence I'm sending it for -rc2.
- io-wq race fix and cleanup (Hao)

impossible to properly use io_uring if you cannot modify the file

When the back channel enters SEQ4_STATUS_CB_PATH_DOWN state, the client
recovers by sending BIND_CONN_TO_SESSION but the server fails to recover
the back channel and leaves it as NFSD4_CB_DOWN.

by calling nfsd4_probe_callback.

tx timeout and slot time are currently specified in units of HZ. On
Alpha, HZ is defined as 1024. When building alpha:allmodconfig, this
results in the following error message.
drivers/net/hamradio/6pack.c: In function 'sixpack_open':
drivers/net/hamradio/6pack.c:71:41: error:
unsigned conversion from 'int' to 'unsigned char'
changes value from '256' to '0'
In the 6PACK protocol, tx timeout is specified in units of 10 ms and
transmitted over the wire:
https://www.linux-ax25.org/wiki/6PACK
Defining a value dependent on HZ doesn't really make sense, and
presumably comes from the (very historical) situation where HZ was
originally 100.
Note that the SIXP_SLOTTIME use explicitly is about 10ms granularity:
mod_timer(&sp->tx_t, jiffies + ((when + 1) * HZ) / 100);
and the SIXP_TXDELAY walue is sent as a byte over the wire.

[ Not so 'new' static annotations any more, and I removed the part of

This driver isn't enabled most places because of the ISA config
dependency, but alpha still has it. And I think the 'Jensen' actually
did have an ISA slot.
However, it doesn't build cleanly, because the "Vortex bus master" code
just casts the skb->data pointer to 'int':
outl((int) (skb->data), ioaddr + Wn7_MasterAddr);
which is all kinds of broken. Even on a good old traditional PC/AT it
would be broken because the high bits will be random kernel address
bits, but presumably the hardware ignores those bits. I mean, it's ISA.
We're talking 16MB dma limits. The "good old days".
Make the build happy with this kind of craziness by using the proper
isa_virt_to_bus() handling that the full bus master code uses anyway
(the Vortex bus mastering is a limited special case).
Who knows, this might even work.

__stack_chk_guard is setup once while init stage and never changed
after that.
Although the modification of this variable at runtime will usually
cause the kernel to crash (so does the attacker), it should be marked
as __ro_after_init, and it should not affect performance if it is
placed in the ro_after_init section.

When we need a buffer for SVE register state we call sve_alloc() to make
sure that one is there. In order to avoid repeated allocations and frees
we keep the buffer around unless we change vector length and just memset()
it to ensure a clean register state. The function that deals with this
takes the task to operate on as an argument, however in the case where we
do a memset() we initialise using the SVE state size for the current task
rather than the task passed as an argument.
This is only an issue in the case where we are setting the register state
for a task via ptrace and the task being configured has a different vector
length to the task tracing it. In the case where the buffer is larger in
the traced process we will leak old state from the traced process to
itself, in the case where the buffer is smaller in the traced process we
will overflow the buffer and corrupt memory.

[Why]
The "base_addr_is_mc_addr" field was added for dcn3.1 support but
pa_config was never updated to set it to false.
Uninitialized memory causes it to be set to true which results in
address mistranslation and white screen.
[How]
Use memset to ensure all fields are initialized to 0 by default.

This patch allows panel orientation quirks from DRM core to be
used. They attach a DRM connector property "panel orientation"
which indicates in which direction the panel has been mounted.
Some machines have the internal screen mounted with a rotation.
Since the panel orientation quirks need the native mode from the
EDID, check for it in amdgpu_dm_connector_ddc_get_modes.

This was unusual; normally, inline functions are declared static as
well, and defined in a header file if used by multiple compilation
units. The latter would be more involved in this case, so just drop
the inline declaration for now.

Current RUNPM mechanism relies on PMFW to master the timing for BACO
in/exit. And that needs cooperation from sound driver for dstate
change notification for function 1(audio). Otherwise(on sound driver
missing), BACO cannot be kicked in correctly and hang will be observed
on RUNPM exit.
By switching back to legacy message way on sound driver missing,
we are able to fix the runpm hang observed for the scenario below:
amdgpu driver loaded -> runpm suspend kicked -> sound driver loaded

[Why]
call stack of amdgpu dsc mst pbn, slot num calculation is as below:
-compute_bpp_x16_from_target_bandwidth
-decide_dsc_target_bpp_x16
-setup_dsc_config
-dc_dsc_compute_bandwidth_range
-compute_mst_dsc_configs_for_link
-compute_mst_dsc_configs_for_state
from pbn -> dsc target bpp_x16
bpp_x16 is calulated by compute_bpp_x16_from_target_bandwidth.
Beside pixel clock and bpp, num_slices_h and bpp_increment_div
will also affect bpp_x16.
from dsc target bpp_x16 -> pbn
within dm_update_mst_vcpi_slots_for_dsc,
pbn = drm_dp_calc_pbn_mode(clock, bpp_x16, true);
drm_dp_calc_pbn_mode(int clock, int bpp, bool dsc)
{
return DIV_ROUND_UP_ULL(mul_u32_u32(clock * (bpp / 16), 64 * 1006),
8 * 54 * 1000 * 1000);
}
bpp / 16 trunc digits after decimal point. This will cause calculation
delta. drm_dp_calc_pbn_mode does not have other informations,
like num_slices_h, bpp_increment_div. therefore, it does not do revese
calcuation properly from bpp_x16 to pbn.
pbn from drm_dp_calc_pbn_mode is less than pbn from
compute_mst_dsc_configs_for_state. This cause not enough mst slot
allocated to display. display could not visually light up.
[How]
pass pbn from compute_mst_dsc_configs_for_state to
dm_update_mst_vcpi_slots_for_dsc
