4329426cf6 ip6_tunnel: fix NEXTHDR_FRAGMENT handling in ip6_tnl_parse_tlv_enc_lim()
[ Upstream commit d375b98e0248980681e5e56b712026174d617198 ]

syzbot pointed out [1] that NEXTHDR_FRAGMENT handling is broken.

Reading frag_off can only be done if we pulled enough bytes
to skb->head. Currently we might access garbage.

d0464a7edf mlxbf_gige: Enable the GigE port in mlxbf_gige_open
[ Upstream commit a460f4a684511e007bbf1700758a41f05d9981e6 ]

At the moment, the GigE port is enabled in the mlxbf_gige_probe
function. If the mlxbf_gige_open is not executed, this could cause
pause frames to increase in the case where there is high backgroud
traffic. This results in clogging the port.
So move enabling the OOB port to mlxbf_gige_open.

86f3df0495 mlxbf_gige: Fix intermittent no ip issue
[ Upstream commit ef210ef85d5cb543ce34a57803ed856d0c8c08c2 ]

Although the link is up, there is no ip assigned on setups with high background
traffic. Nothing is transmitted nor received. The RX error count keeps on
increasing. After several minutes, the RX error count stagnates and the
GigE interface finally gets an ip.

The issue is that mlxbf_gige_rx_init() is called before phy_start().
As soon as the RX DMA is enabled in mlxbf_gige_rx_init(), the RX CI reaches the max
of 128, and becomes equal to RX PI. RX CI doesn't decrease since the code hasn't
ran phy_start yet.
Bring the PHY up before starting the RX.

172ba7d46c net/sched: act_ct: fix skb leak and crash on ooo frags
[ Upstream commit 3f14b377d01d8357eba032b4cabc8c1149b458b6 ]

act_ct adds skb->users before defragmentation. If frags arrive in order,
the last frag's reference is reset in:

  inet_frag_reasm_prepare
    skb_morph

which is not straightforward.

However when frags arrive out of order, nobody unref the last frag, and
all frags are leaked. The situation is even worse, as initiating packet
capture can lead to a crash[0] when skb has been cloned and shared at the
same time.

Fix the issue by removing skb_get() before defragmentation. act_ct
returns TC_ACT_CONSUMED when defrag failed or in progress.

c3d8edb170 null_blk: don't cap max_hw_sectors to BLK_DEF_MAX_SECTORS
[ Upstream commit 9a9525de865410047fa962867b4fcd33943b206f ]

null_blk has some rather odd capping of the max_hw_sectors value to
BLK_DEF_MAX_SECTORS, which doesn't make sense - max_hw_sector is the
hardware limit, and BLK_DEF_MAX_SECTORS despite the confusing name is the
default cap for the max_sectors field used for normal file system I/O.

Remove all the capping, and simply leave it to the block layer or
user to take up or not all of that for file system I/O.

ce3440b699 Bluetooth: btmtkuart: fix recv_buf() return value
[ Upstream commit 64057f051f20c2a2184b9db7f8037d928d68a4f4 ]

Serdev recv_buf() callback is supposed to return the amount of bytes
consumed, therefore an int in between 0 and count.

Do not return negative number in case of issue, just print an error and
return count. This fixes a WARN in ttyport_receive_buf().

166d65b0d5 netfilter: nf_tables: mark newset as dead on transaction abort
[ Upstream commit 08e4c8c5919fd405a4d709b4ba43d836894a26eb ]

If a transaction is aborted, we should mark the to-be-released NEWSET dead,
just like commit path does for DEL and DESTROYSET commands.

In both cases all remaining elements will be released via
set->ops->destroy().

The existing abort code does NOT post the actual release to the work queue.
Also the entire __nf_tables_abort() function is wrapped in gc_seq
begin/end pair.

Therefore, async gc worker will never try to release the pending set
elements, as gc sequence is always stale.

It might be possible to speed up transaction aborts via work queue too,
this would result in a race and a possible use-after-free.

So fix this before it becomes an issue.

[ Upstream commit eed6e57e9f3e2beac37563eb6a0129549daa330e ]

Commit c14e64b46944 ("soc: qcom: llcc: Support chipsets that can
 write to llcc") add the support for chipset where capacity based
allocation and retention through power collapse can be programmed
based on content of SCT table mentioned in the llcc driver where
the target like sdm845 where the entire programming related to it
is controlled in firmware. However, the commit introduces a bug
where capacity/retention register get overwritten each time it
gets programmed for each slice and that results in misconfiguration
of the register based on SCT table and that is not expected
behaviour instead it should be read modify write to retain the
configuration of other slices.

This issue is totally caught from code review and programming test
and not through any power/perf numbers so, it is not known what
impact this could make if we don't have this change however,
this feature are for these targets and they should have been
programmed accordingly as per their configuration mentioned in
SCT table like others bits information.

This change brings one difference where it keeps capacity/retention
bits of the slices that are not mentioned in SCT table in unknown
state where as earlier it was initialized to zero.

SO_RCVLOWAT value of the socket. This is actual for non-default value
of SO_RCVLOWAT (e.g. not 1) - idea is to "kick" peer to continue data
transmission, because we need at least SO_RCVLOWAT bytes in our rx

possible to stuck both tx and rx sides, this is why 'Fixes' is used).

0296268425 bpf: Fix verification of indirect var-off stack access
[ Upstream commit a833a17aeac73b33f79433d7cee68d5cafd71e4f ]

This patch fixes a bug around the verification of possibly-zero-sized
stack accesses. When the access was done through a var-offset stack
pointer, check_stack_access_within_bounds was incorrectly computing the
maximum-offset of a zero-sized read to be the same as the register's min
offset. Instead, we have to take in account the register's maximum
possible value. The patch also simplifies how the max offset is checked;
the check is now simpler than for min offset.

The bug was allowing accesses to erroneously pass the
check_stack_access_within_bounds() checks, only to later crash in
check_stack_range_initialized() when all the possibly-affected stack
slots are iterated (this time with a correct max offset).
check_stack_range_initialized() is relying on
check_stack_access_within_bounds() for its accesses to the
stack-tracking vector to be within bounds; in the case of zero-sized
accesses, we were essentially only verifying that the lowest possible
slot was within bounds. We would crash when the max-offset of the stack
pointer was >= 0 (which shouldn't pass verification, and hopefully is
not something anyone's code attempts to do in practice).

Thanks Hao for reporting!

When register is spilled onto a stack as a 1/2/4-byte register, we set
slot_type[BPF_REG_SIZE - 1] (plus potentially few more below it,
depending on actual spill size). So to check if some stack slot has
spilled register we need to consult slot_type[7], not slot_type[0].

To avoid the need to remember and double-check this in the future, just
use is_spilled_reg() helper.

[ Upstream commit 7ac90b4cf107a3999b30844d7899e0331686b33b ]

On sc7180 when the watchdog timer fires your logs get filled with:
  watchdog0: pretimeout event
  watchdog0: pretimeout event
  watchdog0: pretimeout event
  ...
  watchdog0: pretimeout event

If you're using console-ramoops to debug crashes the above gets quite
annoying since it blows away any other log messages that might have
been there.

The issue is that the "bark" interrupt (AKA the "pretimeout"
interrupt) remains high until the watchdog is pet. Since we've got
things configured as "level" triggered we'll keep getting interrupted
over and over.

Let's switch to edge triggered. Now we'll get one interrupt when the
"bark" interrupt goes off and won't get another one until the "bark"
interrupt is cleared and asserts again.

This matches how many older Qualcomm SoCs have things configured.

[ Upstream commit b57160859263c083c49482b0d083a586b1517f78 ]

DSS irq trigger type is set to IRQ_TYPE_EDGE_RISING in the DT file, but
the TRM says it is level triggered.

For some reason triggering on rising edge results in double the amount
of expected interrupts, e.g. for normal page flipping test the number of
interrupts per second is 2 * fps. It is as if the IRQ triggers on both
edges. There are no other side effects to this issue than slightly
increased CPU & power consumption due to the extra interrupt.

Switching to IRQ_TYPE_LEVEL_HIGH is correct and fixes the issue, so
let's do that.
