Make napi_hash_lock IRQ safe. It is used during the control path, and is
taken and released in napi_hash_add and napi_hash_del, which will
typically be called by calls to napi_enable and napi_disable.
This change avoids a deadlock in pcnet32 (and other any other drivers
which follow the same pattern):
CPU 0:
pcnet32_open
spin_lock_irqsave(&lp->lock, ...)
napi_enable
napi_hash_add <- before this executes, CPU 1 proceeds
spin_lock(napi_hash_lock)
[...]
spin_unlock_irqrestore(&lp->lock, flags);
CPU 1:
pcnet32_close
napi_disable
napi_hash_del
spin_lock(napi_hash_lock)
< INTERRUPT >
pcnet32_interrupt
spin_lock(lp->lock) <- DEADLOCK
Changing the napi_hash_lock to be IRQ safe prevents the IRQ from firing
on CPU 1 until napi_hash_lock is released, preventing the deadlock.

Catalin reports that a hypervisor lying to a guest about the size
of the ASID field may result in unexpected issues:
- if the underlying HW does only supports 8 bit ASIDs, the ASID
field in a TLBI VAE1* operation is only 8 bits, and the HW will
ignore the other 8 bits
- if on the contrary the HW is 16 bit capable, the ASID field
in the same TLBI operation is always 16 bits, irrespective of
the value of TCR_ELx.AS.
This could lead to missed invalidations if the guest was lead to
assume that the HW had 8 bit ASIDs while they really are 16 bit wide.
In order to avoid any potential disaster that would be hard to debug,
prenent the migration between a host with 8 bit ASIDs to one with
wider ASIDs (the converse was obviously always forbidden). This is
also consistent with what we already do for VMIDs.
If it becomes absolutely mandatory to support such a migration path
in the future, we will have to trap and emulate all TLBIs, something
that nobody should look forward to.

The IRQ indexes for the intf_6 underrun/vsync interrupts are swapped.
DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 16) is the actual underrun interrupt and
DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 17) is the vsync interrupt.
This causes timeout errors when using the DP2 controller, e.g.
[dpu error]enc37 frame done timeout
*ERROR* irq timeout id=37, intf_mode=INTF_MODE_VIDEO intf=6 wb=-1, pp=2, intr=0

the Documentration that state that the BUS runs at 300MHz (600MHz source
with divisor set to 2) and the actual watchdog that tick at half the BUS
clock (150MHz). This was verified with the watchdog by timing the
seconds that the system takes to reboot (due too watchdog) and by
operating on different values of the BUS divisor.
The correct values for source of BUS clock are 600MHz and 540MHz.

The error is caused by `objtree` variable changing definition from `.`

- The variable TPROGS_CFLAGS is constructed as follows:

- It is passed as EXTRA_CFLAGS for libbpf compilation:

- Before commit [0], the line passed to libbpf makefile was
'-I./usr/include', where '.' referred to LIBBPF_SRC due to -C flag.
The directory $(LIBBPF_SRC)/usr/include does not exist and thus
was never resolved by C compiler.
- After commit [0], the line passed to libbpf makefile became:
'<output-dir>/usr/include', this directory exists and is resolved by

- Both 'tools/include' and 'usr/include' define files err.h and types.h.
- libbpf expects headers like 'linux/err.h' and 'linux/types.h'
defined in 'tools/include', not 'usr/include', hence the compilation
error.
This commit removes unnecessary -I flags from libbpf compilation.

1) If the NFT_PKTINFO_INNER_FULL flag is set on, then this skbuff
has already been parsed before for inner header fetching to
register.
2) Validate that the percpu area refers to this skbuff using the
skbuff pointer as a cookie. If there is a cookie mismatch, then
this skbuff needs to be parsed again.
3) Finally, validate if the percpu area refers to this tunnel type.

[BUG]
The following reproducer can cause btrfs mount to fail:
dev="/dev/test/scratch1"
mnt1="/mnt/test"
mnt2="/mnt/scratch"
mkfs.btrfs -f $dev
mount $dev $mnt1

while mount $dev $mnt2 -o subvol=subvol2; do umount $mnt2; done

umount -R $mnt2
The script will fail with the following error:
mount: /mnt/scratch: /dev/mapper/test-scratch1 already mounted on /mnt/test.
dmesg(1) may have more information after failed mount system call.
umount: /mnt/test: target is busy.
umount: /mnt/scratch/: not mounted
And there is no kernel error message.
[CAUSE]
During the btrfs mount, to support mounting different subvolumes with
different RO/RW flags, we need to detect that and retry if needed:
Retry with matching RO flags if the initial mount fail with -EBUSY.
The problem is, during that retry we do not hold any super block lock
(s_umount), this means there can be a remount process changing the RO
flags of the original fs super block.
If so, we can have an EBUSY error during retry. And this time we treat
any failure as an error, without any retry and cause the above EBUSY
mount failure.
[FIX]
The current retry behavior is racy because we do not have a super block
thus no way to hold s_umount to prevent the race with remount.
Solve the root problem by allowing fc->sb_flags to mismatch from the
sb->s_flags at btrfs_get_tree_super().
Then at the re-entry point btrfs_get_tree_subvol(), manually check the
fc->s_flags against sb->s_flags, if it's a RO->RW mismatch, then
reconfigure with s_umount lock hold.

The quirk was initially used as a signal to set the discard_zeroes_data
queue limit because there were some use cases that relied on that
behavior. The queue limit no longer exists as every user of it has been
converted to use the write zeroes operation instead.
The quirk now means to use a discard command as an alias to a write
zeroes request. Two of the devices previously using the quirk support
the write zeroes command directly, so these don't need or want to use
discard when the desired operation is to write zeroes.

SFF-8472 (section 5.4 Transceiver Compliance Codes) defines bit 6 as
BASE-BX10. Bit 6 means a value of 0x40 (decimal 64).
The current value in the source code is 0x64, which appears to be a
mix-up of hex and decimal values. A value of 0x64 (binary 01100100)
incorrectly sets bit 2 (1000BASE-CX) and bit 5 (100BASE-FX) as well.

The ixgbe PF driver logs an info message when a VF attempts to negotiate an
API version which it does not support:
VF 0 requested invalid api version 6
The ixgbevf driver attempts to load with mailbox API v1.5, which is
required for best compatibility with other hosts such as the ESX VMWare PF.
The Linux PF only supports API v1.4, and does not currently have support
for the v1.5 API.
The logged message can confuse users, as the v1.5 API is valid, but just
happens to not currently be supported by the Linux PF.
Downgrade the info message to a debug message, and fix the language to
use 'unsupported' instead of 'invalid' to improve message clarity.
Long term, we should investigate whether the improvements in the v1.5 API
make sense for the Linux PF, and if so implement them properly. This may
require yet another API version to resolve issues with negotiating IPSEC
offload support.

Commit 339f289641 ("ixgbevf: Add support for new mailbox communication
between PF and VF") added support for v1.5 of the PF to VF mailbox
communication API. This commit mistakenly enabled IPSEC offload for API
v1.5.
No implementation of the v1.5 API has support for IPSEC offload. This
offload is only supported by the Linux PF as mailbox API v1.4. In fact, the
v1.5 API is not implemented in any Linux PF.
Attempting to enable IPSEC offload on a PF which supports v1.5 API will not
work. Only the Linux upstream ixgbe and ixgbevf support IPSEC offload, and
only as part of the v1.4 API.
Fix the ixgbevf Linux driver to stop attempting IPSEC offload when
the mailbox API does not support it.
The existing API design choice makes it difficult to support future API
versions, as other non-Linux hosts do not implement IPSEC offload. If we
add support for v1.5 to the Linux PF, then we lose support for IPSEC
offload.
A full solution likely requires a new mailbox API with a proper negotiation
to check that IPSEC is actually supported by the host.

Commit d9028db618 ("idpf: convert to libeth Tx buffer completion")
inadvertently removed code that was necessary for the tx buffer cleaning
routine to iterate over all buffers associated with a packet.
When a frag is too large for a single data descriptor, it will be split
across multiple data descriptors. This means the frag will span multiple
buffers in the buffer ring in order to keep the descriptor and buffer
ring indexes aligned. The buffer entries in the ring are technically
empty and no cleaning actions need to be performed. These empty buffers
can precede other frags associated with the same packet. I.e. a single
packet on the buffer ring can look like:
buf[0]=skb0.frag0
buf[1]=skb0.frag1
buf[2]=empty
buf[3]=skb0.frag2
The cleaning routine iterates through these buffers based on a matching
completion tag. If the completion tag is not set for buf2, the loop will
end prematurely. Frag2 will be left uncleaned and next_to_clean will be
left pointing to the end of packet, which will break the cleaning logic
for subsequent cleans. This consequently leads to tx timeouts.
Assign the empty bufs the same completion tag for the packet to ensure
the cleaning routine iterates over all of the buffers associated with
the packet.

In switchdev mode the uplink VSI should receive all unmatched packets,
including VLANs. Therefore, VLAN pruning should be disabled if uplink is
in switchdev mode. It is already being done in ice_eswitch_setup_env(),
however the addition of ice_up() in commit 44ba608db5 ("ice: do
switchdev slow-path Rx using PF VSI") caused VLAN pruning to be
re-enabled after disabling it.
Add a check to ice_set_vlan_filtering_features() to ensure VLAN
filtering will not be enabled if uplink is in switchdev mode. Note that
ice_is_eswitch_mode_switchdev() is being used instead of
ice_is_switchdev_running(), as the latter would only return true after
the whole switchdev setup completes.
