While enabling EDAC support for the LS1028A it was discovered that the
memory node has a wrong endianness setting as well as a wrong interrupt
assignment. Fix both.
This was tested on a sl28 board. To force ECC errors, you can use the
error injection supported by the controller in hardware (with
CONFIG_EDAC_DEBUG enabled):
# enable error injection
$ echo 0x100 > /sys/devices/system/edac/mc/mc0/inject_ctrl
# flip lowest bit of the data

If the hardware is still accessing memory after SMMU translation
is disabled (as part of smmu shutdown callback), then the
IOVAs (I/O virtual address) which it was using will go on the bus
as the physical addresses which will result in unknown crashes
like NoC/interconnect errors.
So, implement shutdown callback for i2c driver to suspend the bus
during system "reboot" or "shutdown".

[ Upstream commit f9f83202b7263ac371d616d6894a2c9ed79158ef ]
Currently in the ice driver, the check whether to
allow a LLDP packet to egress the interface from the
PF_VSI is being based on the SKB's priority field.
It checks to see if the packets priority is equal to
TC_PRIO_CONTROL. Injected LLDP packets do not always
meet this condition.
SCAPY defaults to a sk_buff->protocol value of ETH_P_ALL
(0x0003) and does not set the priority field. There will
be other injection methods (even ones used by end users)
that will not correctly configure the socket so that
SKB fields are correctly populated.
Then ethernet header has to have to correct value for
the protocol though.
Add a check to also allow packets whose ethhdr->h_proto
matches ETH_P_LLDP (0x88CC).

Add the ct helper extension only for unconfirmed conntrack. Skip rule

It should be possible to remove this limitation by adding a new action
to attach a generic ct helper to the first packet. Then, use this ct

While at it, add a missing check to skip the template conntrack too

[ Upstream commit fb91702b743dec78d6507c53a2dec8a8883f509d ]
Fix current behavior of skipping template allocation in case the
ct action is in zone 0.
Skipping the allocation may cause the datapath ct code to ignore the
entire ct action with all its attributes (commit, nat) in case the ct
action in zone 0 was preceded by a ct clear action.
The ct clear action sets the ct_state to untracked and resets the
skb->_nfct pointer. Under these conditions and without an allocated
ct template, the skb->_nfct pointer will remain NULL which will
cause the tc ct action handler to exit without handling commit and nat
actions, if such exist.
For example, the following rule in OVS dp:
recirc_id(0x2),ct_state(+new-est-rel-rpl+trk),ct_label(0/0x1), \
in_port(eth0),actions:ct_clear,ct(commit,nat(src=10.11.0.12)), \
recirc(0x37a)
Will result in act_ct skipping the commit and nat actions in zone 0.
The change removes the skipping of template allocation for zone 0 and
treats it the same as any other zone.

guarantees nul-termination, so doing it manually afterwards is
pointless.
It's even potentially harmful (though probably not in practice because
CPER_REC_LEN is 256), due to the "return how much would have been
written had the buffer been big enough" semantics. I.e., if the bank

commit 2d9463083ce92636a1bdd3e30d1236e3e95d859e upstream
syzbot discovered a bug in which an OOB access was being made because
an unsuitable key_idx value was wrongly considered to be acceptable
while deleting a key in nl80211_del_key().
Since we don't know the cipher at the time of deletion, if
cfg80211_validate_key_settings() were to be called directly in
nl80211_del_key(), even valid keys would be wrongly determined invalid,
and deletion wouldn't occur correctly.
For this reason, a new function - cfg80211_valid_key_idx(), has been
created, to determine if the key_idx value provided is valid or not.
cfg80211_valid_key_idx() is directly called in 2 places -
nl80211_del_key(), and cfg80211_validate_key_settings().

commit 1119a72e223f3073a604f8fccb3a470ccd8a4416 upstream.
The tree checker checks the extent ref hash at read and write time to
make sure we do not corrupt the file system. Generally extent
references go inline, but if we have enough of them we need to make an
item, which looks like
key.objectid = <bytenr>
key.type = <BTRFS_EXTENT_DATA_REF_KEY|BTRFS_TREE_BLOCK_REF_KEY>
key.offset = hash(tree, owner, offset)
However if key.offset collide with an unrelated extent reference we'll
simply key.offset++ until we get something that doesn't collide.
Obviously this doesn't match at tree checker time, and thus we error
while writing out the transaction. This is relatively easy to
reproduce, simply do something like the following
xfs_io -f -c "pwrite 0 1M" file
offset=2
for i in {0..10000}
do
xfs_io -c "reflink file 0 ${offset}M 1M" file
offset=$(( offset + 2 ))
done
xfs_io -c "reflink file 0 17999258914816 1M" file
xfs_io -c "reflink file 0 35998517829632 1M" file
xfs_io -c "reflink file 0 53752752058368 1M" file
btrfs filesystem sync
And the sync will error out because we'll abort the transaction. The
magic values above are used because they generate hash collisions with
the first file in the main subvol.
The fix for this is to remove the hash value check from tree checker, as
we have no idea which offset ours should belong to.

commit eefb45eef5c4c425e87667af8f5e904fbdd47abf upstream.
Following Race Condition was detected:
<CPU A, t0>: Executing: __netif_receive_skb() ->__netif_receive_skb_core()
-> arp_rcv() -> arp_process().arp_process() calls __neigh_lookup() which
takes a reference on neighbour entry 'n'.
Moves further along, arp_process() and calls neigh_update()->
__neigh_update(). Neighbour entry is unlocked just before a call to
neigh_update_gc_list.
This unlocking paves way for another thread that may take a reference on
the same and mark it dead and remove it from gc_list.
<CPU B, t1> - neigh_flush_dev() is under execution and calls
neigh_mark_dead(n) marking the neighbour entry 'n' as dead. Also n will be
removed from gc_list.
Moves further along neigh_flush_dev() and calls
neigh_cleanup_and_release(n), but since reference count increased in t1,
'n' couldn't be destroyed.
<CPU A, t3>- Code hits neigh_update_gc_list, with neighbour entry
set as dead.
<CPU A, t4> - arp_process() finally calls neigh_release(n), destroying
the neighbour entry and we have a destroyed ntry still part of gc_list.

The register reads should be OK, because the current
implementation of readl and friends will always execute even
without an lvalue.
When it makes sense, just remove the lvalue assignment and the
local. Other times, just remove the offending code, and
occasionally, just mark the variable as maybe unused since it
could be used in an ifdef or debug scenario.
Only compile tested with W=1.

This commit just extends the original array by 2 zero-initialized bytes,
avoiding the warning.
There may be some underlying bug in here that caused this confusion, but
this is at least no worse than the existing situation that could use

[ Upstream commit 63e39d29b3da02e901349f6cd71159818a4737a6 ]

range of MTUs before attempting to set the VF large packet enable,
otherwise reject the request. This also avoids unnecessary
register updates in the case of the 82599 controller.
