In routine c2h_wk_callback(() following a kmalloc() call, the
error recovery is flawed. If the kmalloc() returns a pointer
that is not NULL, and the following c2h_evt_read() fails, the
code will leak that buffer. If the kmalloc() fails, a NULL
dereference will occur in the following code.

bits when the device supports per vector masking. For MSI-X it's used to

Multi-MSI uses a single MSI descriptor and there is a single mask register
when the device supports per vector masking. To avoid reading back the mask
register the value is cached in the MSI descriptor and updates are done by
clearing and setting bits in the cache and writing it to the device.
But nothing protects msi_desc::masked and the mask register from being
modified concurrently on two different CPUs for two different Linux
interrupts which belong to the same multi-MSI descriptor.
Add a lock to struct device and protect any operation on the mask and the
mask register with it.
This makes the update of msi_desc::masked unconditional, but there is no
place which requires a modification of the hardware register without
updating the masked cache.
msi_mask_irq() is now an empty wrapper which will be cleaned up in follow
up changes.
The problem goes way back to the initial support of multi-MSI, but picking
the commit which introduced the mask cache is a valid cut off point
(2.6.30).

msi_mask_irq() takes a mask and a flags argument. The mask argument is used
to mask out bits from the cached mask and the flags argument to set bits.
Some places invoke it with a flags argument which sets bits which are not
used by the device, i.e. when the device supports up to 8 vectors a full
unmask in some places sets the mask to 0xFFFFFF00. While devices probably
do not care, it's still bad practice.

Nothing enforces the posted writes to be visible when the function
returns. Flush them even if the flush might be redundant when the entry is
masked already as the unmask will flush as well. This is either setup or a
rare affinity change event so the extra flush is not the end of the world.
While this is more a theoretical issue especially the logic in the X86
specific msi_set_affinity() function relies on the assumption that the
update has reached the hardware when the function returns.
Again, as this never has been enforced the Fixes tag refers to a commit in:

The specification (PCIe r5.0, sec 6.1.4.5) states:
For MSI-X, a function is permitted to cache Address and Data values
from unmasked MSI-X Table entries. However, anytime software unmasks a
currently masked MSI-X Table entry either by clearing its Mask bit or
by clearing the Function Mask bit, the function must update any Address
or Data values that it cached from that entry. If software changes the
Address or Data value of an entry while the entry is unmasked, the
result is undefined.
The Linux kernel's MSI-X support never enforced that the entry is masked
before the entry is modified hence the Fixes tag refers to a commit in:
git://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git
Enforce the entry to be masked across the update.
There is no point in enforcing this to be handled at all possible call
sites as this is just pointless code duplication and the common update
function is the obvious place to enforce this.

When MSI-X is enabled the ordering of calls is:
msix_map_region();
msix_setup_entries();
pci_msi_setup_msi_irqs();
msix_program_entries();
This has a few interesting issues:
1) msix_setup_entries() allocates the MSI descriptors and initializes them
except for the msi_desc:masked member which is left zero initialized.
2) pci_msi_setup_msi_irqs() allocates the interrupt descriptors and sets
up the MSI interrupts which ends up in pci_write_msi_msg() unless the
interrupt chip provides its own irq_write_msi_msg() function.
3) msix_program_entries() does not do what the name suggests. It solely
updates the entries array (if not NULL) and initializes the masked
member for each MSI descriptor by reading the hardware state and then
masks the entry.
Obviously this has some issues:
1) The uninitialized masked member of msi_desc prevents the enforcement
of masking the entry in pci_write_msi_msg() depending on the cached
masked bit. Aside of that half initialized data is a NONO in general
2) msix_program_entries() only ensures that the actually allocated entries
are masked. This is wrong as experimentation with crash testing and
crash kernel kexec has shown.
This limited testing unearthed that when the production kernel had more
entries in use and unmasked when it crashed and the crash kernel
allocated a smaller amount of entries, then a full scan of all entries
found unmasked entries which were in use in the production kernel.
This is obviously a device or emulation issue as the device reset
should mask all MSI-X table entries, but obviously that's just part
of the paper specification.
Cure this by:
1) Masking all table entries in hardware
2) Initializing msi_desc::masked in msix_setup_entries()
3) Removing the mask dance in msix_program_entries()
4) Renaming msix_program_entries() to msix_update_entries() to
reflect the purpose of that function.
As the masking of unused entries has never been done the Fixes tag refers
to a commit in:

The ordering of MSI-X enable in hardware is dysfunctional:
1) MSI-X is disabled in the control register
2) Various setup functions
3) pci_msi_setup_msi_irqs() is invoked which ends up accessing
the MSI-X table entries
4) MSI-X is enabled and masked in the control register with the
comment that enabling is required for some hardware to access
the MSI-X table
Step #4 obviously contradicts #3. The history of this is an issue with the
NIU hardware. When #4 was introduced the table access actually happened in
msix_program_entries() which was invoked after enabling and masking MSI-X.
This was changed in commit d71d6432e105 ("PCI/MSI: Kill redundant call of
irq_set_msi_desc() for MSI-X interrupts") which removed the table write
from msix_program_entries().
Interestingly enough nobody noticed and either NIU still works or it did
not get any testing with a kernel 3.19 or later.
Nevertheless this is inconsistent and there is no reason why MSI-X can't be
enabled and masked in the control register early on, i.e. move step #4
above to step #1. This preserves the NIU workaround and has no side effects
on other hardware.

Currently ksz8_port_vlan_filtering() sets or clears the VLAN Enable

has not been enabled for any port on the switch.
Since it is a global flag, set the dsa_switch::vlan_filtering_is_global
flag so that the DSA core understands this can't be controlled per
port.
When VLAN filtering is enabled, the switch should also discard packets
with a VID that's not enabled on the ingress port. Set or clear each
external port's VLAN Ingress Filter flag in ksz8_port_vlan_filtering()
to make that happen.

When a VLAN is deleted from a port, the flags in struct
switchdev_obj_port_vlan are always 0. ksz8_port_vlan_del() copies the
BRIDGE_VLAN_INFO_UNTAGGED flag to the port's Tag Removal flag, and
therefore always clears it.
In case there are multiple VLANs configured as untagged on this port -
which seems useless, but is allowed - deleting one of them changes the
remaining VLANs to be tagged.
It's only ever necessary to change this flag when a VLAN is added to
the port, so leave it unchanged in ksz8_port_vlan_del().

Removal. This means it is not possible to support both tagged and

configured.
VID 0 is excluded from this check since it is untagged regardless of

ksz8795 has never actually enabled PVID tag insertion, and it also
programmed the PVID incorrectly. To fix this:
* Allow tag insertion to be controlled per ingress port. On most
chips, set bit 2 in Global Control 19. On KSZ88x3 this control
flag doesn't exist.
* When adding a PVID:
- Set the appropriate register bits to enable tag insertion on
egress at every other port if this was the packet's ingress port.
- Mask *out* the VID from the default tag, before or-ing in the new
PVID.
* When removing a PVID:
- Clear the same control bits to disable tag insertion.
- Don't update the default tag. This wasn't doing anything useful.

ksz_read64() currently does some dubious byte-swapping on the two
halves of a 64-bit register, and then only returns the high bits.
Replace this with a straightforward expression.

Pull EFI fixes from Ard Biesheuvel:
A batch of fixes for the arm64 stub image loader:
- fix a logic bug that can make the random page allocator fail
spuriously
- force reallocation of the Image when it overlaps with firmware
reserved memory regions
- fix an oversight that defeated on optimization introduced earlier
where images loaded at a suitable offset are never moved if booting
without randomization
- complain about images that were not loaded at the right offset by the
firmware image loader.

Add support for the OSD1 HDR registers so meson DRM can handle the HDR
properties set by Amlogic u-boot on G12A and newer devices which result
in blue/green/pink colour distortion to display output.
This takes the original patch submissions from Mathias [0] and [1] with
corrections for formatting and the missing description and attribution
needed for merge.

This patch fixes the setting of the M_CAN_DBTP register contents:
- use DBTP_ (the data bitrate macros) instead of NBTP_ which area used
for the nominal bitrate
- do not overwrite possibly-existing DBTP_TDC flag by ORing reg_btp
instead of overwriting

The CQ destroy is performed based on the IRQ number that is stored in
cq->irqn. That number wasn't set explicitly during CQ creation and as
expected some of the API users of mlx5_core_create_cq() forgot to update
it.
This caused to wrong synchronization call of the wrong IRQ with a number
0 instead of the real one.
As a fix, set the IRQ number directly in the mlx5_core_create_cq() and
update all users accordingly.

mlx5e_close_xdpsq does the cleanup: it calls mlx5e_free_xdpsq_descs to
free the outstanding descriptors, which relies on
mlx5e_page_release_dynamic and page_pool_release_page. However,
page_pool_destroy is already called by this point, because
mlx5e_close_rq runs before mlx5e_close_xdpsq.
This commit fixes the use-after-free by swapping mlx5e_close_xdpsq and
mlx5e_close_rq.
The commit cited below started calling page_pool_destroy directly from
the driver. Previously, the page pool was destroyed under a call_rcu
from xdp_rxq_info_unreg_mem_model, which would defer the deallocation
until after the XDPSQ is cleaned up.
