[ Upstream commit 23a5b9b12d ]
Improve the cleanup on releasing PTP resources in error path.
The error case might happen either at the driver probe and PTP
feature initialization or on PTP restart (errors in reset handling, NVM
update etc). In both cases, calls to PF PTP cleanup (ice_ptp_cleanup_pf
function) and 'ps_lock' mutex deinitialization were missed.
Additionally, ptp clock was not unregistered in the latter case.
Keep PTP state as 'uninitialized' on init to distinguish between error
scenarios and to avoid resource release duplication at driver removal.
The consequence of missing ice_ptp_cleanup_pf call is the following call
trace dumped when ice_adapter object is freed (port list is not empty,
as it is required at this stage):

ret_set_ksft_status() calls ksft_status_merge() with the current return
status and the last one. It treats a non-zero return code from
ksft_status_merge() as an indication that the return status was
overwritten by the last one and therefore overwrites the return message
with the last one.
Currently, ksft_status_merge() returns a non-zero return code even if
the current return status and the last one are equal. This results in
return messages being overwritten which is counter-productive since we
are more interested in the first failure message and not the last one.
Fix by changing ksft_status_merge() to only return a non-zero return
code if the current return status was actually changed.
Add a test case which checks that the first error message is not
overwritten.

[ Upstream commit dfe28c4167 ]
The validation of the set(nsh(...)) action is completely wrong.
It runs through the nsh_key_put_from_nlattr() function that is the
same function that validates NSH keys for the flow match and the
push_nsh() action. However, the set(nsh(...)) has a very different
memory layout. Nested attributes in there are doubled in size in
case of the masked set(). That makes proper validation impossible.
There is also confusion in the code between the 'masked' flag, that
says that the nested attributes are doubled in size containing both
the value and the mask, and the 'is_mask' that says that the value
we're parsing is the mask. This is causing kernel crash on trying to
write into mask part of the match with SW_FLOW_KEY_PUT() during
validation, while validate_nsh() doesn't allocate any memory for it:

The third issue with this process is that while trying to convert
the non-masked set into masked one, validate_set() copies and doubles
the size of the OVS_KEY_ATTR_NSH as if it didn't have any nested
attributes. It should be copying each nested attribute and doubling
them in size independently. And the process must be properly reversed
during the conversion back from masked to a non-masked variant during
the flow dump.
In the end, the only two outcomes of trying to use this action are
either validation failure or a kernel crash. And if somehow someone
manages to install a flow with such an action, it will most definitely
not do what it is supposed to, since all the keys and the masks are
mixed up.
Fixing all the issues is a complex task as it requires re-writing
most of the validation code.
Given that and the fact that this functionality never worked since
introduction, let's just remove it altogether. It's better to
re-introduce it later with a proper implementation instead of trying
to fix it in stable releases.

[ Upstream commit 61fafbee6c ]
The GSO segmentation functions for ESP tunnel mode
(xfrm4_tunnel_gso_segment and xfrm6_tunnel_gso_segment) were
determining the inner packet's L2 protocol type by checking the static
x->inner_mode.family field from the xfrm state.
This is unreliable. In tunnel mode, the state's actual inner family
could be defined by x->inner_mode.family or by
x->inner_mode_iaf.family. Checking only the former can lead to a
mismatch with the actual packet being processed, causing GSO to create
segments with the wrong L2 header type.
This patch fixes the bug by deriving the inner mode directly from the
packet's inner protocol stored in XFRM_MODE_SKB_CB(skb)->protocol.
Instead of replicating the code, this patch modifies the
xfrm_ip2inner_mode helper function. It now correctly returns
&x->inner_mode if the selector family (x->sel.family) is already
specified, thereby handling both specific and AF_UNSPEC cases
appropriately.
With this change, ESP GSO can use xfrm_ip2inner_mode to get the
correct inner mode. It doesn't affect existing callers, as the updated
logic now mirrors the checks they were already performing externally.

while it's still powered on, the cached cursor_state
(dpp_base->pos.cur0_ctl.bits.cur0_enable)
and the actual state (CUR0_ENABLE) bit are unsycned. This can cause a

commit 80d8a9ad15 upstream.
[Why]
Accoreding to CP updated to RS64 on gfx11,
WRITE_DATA with PREEMPTION_META_MEMORY(dst_sel=8) is illegal for CP FW.
That packet is used for MCBP on F32 based system.
So it would lead to incorrect GRBM write and FW is not handling that
extra case correctly.
[How]
With gfx11 rs64 enabled, skip emit de meta data.

During the suspend sequence VPE is already going to be power gated
as part of vpe_suspend(). It's unnecessary to call during calls to
amdgpu_device_set_pg_state().
It actually can expose a race condition with the firmware if s0i3

Delete the attempt to progress the queue when checking if fence is
signaled. This avoids deadlock.
dma-fence_ops::signaled can be called with the fence lock in unknown
state. For radeon, the fence lock is also the wait queue lock. This can
cause a self deadlock when signaled() tries to make forward progress on
the wait queue. But advancing the queue is unneeded because incorrectly
returning false from signaled() is perfectly acceptable.

commit fff0c87996 upstream.
With the current fastclose implementation, the mptcp_do_fastclose()
helper is in charge of two distinct actions: send the fastclose reset
and cleanup the subflows.
Formally decouple the two steps, ensuring that mptcp explicitly closes
all the subflows after the mentioned helper.
This will make the upcoming fix simpler, and allows dropping the 2nd
argument from mptcp_destroy_common(). The Fixes tag is then the same as
in the next commit to help with the backports.

commit 4f102d747c upstream.
The rcv window is shared among all the subflows. Currently, MPTCP sync
the TCP-level rcv window with the MPTCP one at tcp_transmit_skb() time.
The above means that incoming data may sporadically observe outdated
TCP-level rcv window and being wrongly dropped by TCP.
Address the issue checking for the edge condition before queuing the
data at TCP level, and eventually syncing the rcv window as needed.
Note that the issue is actually present from the very first MPTCP
implementation, but backports older than the blamed commit below will
range from impossible to useless.

In rare cases, when the test environment is very slow, some userspace
tests can fail because some expected events have not been seen.
Because the tests are expecting a long on-going connection, and they are
not waiting for the end of the transfer, it is fine to have a longer
timeout, and even go over the default one. This connection will be
killed at the end, after the verifications: increasing the timeout
doesn't change anything, apart from avoiding it to end before the end of
the verifications.
To play it safe, all userspace tests not waiting for the end of the

The Fixes commit was making the connection longer, but still, the

commit 17393fa7b7 upstream.
I'm observing very frequent self-tests failures in case of fallback when
running on a CONFIG_PREEMPT kernel.
The root cause is that subflow_sched_work_if_closed() closes any subflow
as soon as it is half-closed and has no incoming data pending.
That works well for regular subflows - MPTCP needs bi-directional
connectivity to operate on a given subflow - but for fallback socket is
race prone.
When TCP peer closes the connection before the MPTCP one,
subflow_sched_work_if_closed() will schedule the MPTCP worker to
gracefully close the subflow, and shortly after will do another schedule
to inject and process a dummy incoming DATA_FIN.
On CONFIG_PREEMPT kernel, the MPTCP worker can kick-in and close the
fallback subflow before subflow_sched_work_if_closed() is able to create
the dummy DATA_FIN, unexpectedly interrupting the transfer.
Address the issue explicitly avoiding closing fallback subflows on when
the peer is only half-closed.
Note that, when the subflow is able to create the DATA_FIN before the
worker invocation, the worker will change the msk state before trying to
close the subflow and will skip the latter operation as the msk will not
match anymore the precondition in __mptcp_close_subflow().

commit ae15506024 upstream.
The CI reports sporadic failures of the fastclose self-tests. The root
cause is a duplicate reset, not carrying the relevant MPTCP option.
In the failing scenario the bad reset is received by the peer before
the fastclose one, preventing the reception of the latter.
Indeed there is window of opportunity at fastclose time for the
following race:
mptcp_do_fastclose
__mptcp_close_ssk
__tcp_close()
tcp_set_state() [1]
tcp_send_active_reset() [2]
After [1] the stack will send reset to in-flight data reaching the now
closed port. Such reset may race with [2].
Address the issue explicitly sending a single reset on fastclose before
explicitly moving the subflow to close status.

commit 5e15395f6d upstream.
mptcp_cleanup_rbuf() needs to know the last most recent, mptcp-level

field, updated at ack transmission time by mptcp_write_options().
Fallback socket do not add any mptcp options, such helper is never
invoked, and msk->old_wspace value remain stale. That in turn makes
ack generation at recvmsg() time quite random.
Address the issue ensuring mptcp_write_options() is invoked even for
fallback sockets, and just update the needed info in such a case.
The issue went unnoticed for a long time, as mptcp currently overshots
the fallback socket receive buffer autotune significantly. It is going
to change in the near future.

commit ebd729fef3 upstream.
Fix a regression that has caused accesses to the PCI MMIO window to
complete unclaimed in non-EVA configurations with the SOC-it family of
system controllers, preventing PCI devices from working that use MMIO.
In the non-EVA case PHYS_OFFSET is set to 0, meaning that PCI_BAR0 is
set with an empty mask (and PCI_HEAD4 matches addresses starting from 0
accordingly). Consequently all addresses are matched for incoming DMA
accesses from PCI. This seems to confuse the system controller's logic
and outgoing bus cycles targeting the PCI MMIO window seem not to make
it to the intended devices.
This happens as well when a wider mask is used with PCI_BAR0, such as
0x80000000 or 0xe0000000, that makes addresses match that overlap with
the PCI MMIO window, which starts at 0x10000000 in our configuration.
Set the mask in PCI_BAR0 to 0xf0000000 for non-EVA then, covering the
non-EVA maximum 256 MiB of RAM, which is what YAMON does and which used
to work correctly up to the offending commit. Set PCI_P2SCMSKL to match
PCI_BAR0 as required by the system controller's specification, and match
PCI_P2SCMAPL to PCI_HEAD4 for identity mapping.

is definitely wrong because the ctr->ref is grabbed when submitting

And Marco observed that nvme_fc_ctrl_free() can be called from request
completion code path, and trigger kernel warning since request completes
from softirq context.
Fix the issue by moveing target removal into nvme_fc_delete_ctrl(),
which is also aligned with nvme-tcp and nvme-rdma.
Patch originally proposed by Ming Lei, then modified to move the tagset
removal down to after nvme_fc_delete_association() after further testing.

to force the allocation of a very small buffer.
Subsequently, if the device sends an interrupt packet with a specific
pattern (e.g., where the first byte is 0x80 or 0x42),
the pegasus_parse_packet() function parses the packet without checking
the allocated buffer size. This leads to an out-of-bounds memory access.

commit d83f151275 upstream.
This is supposed to be "priv" but we accidentally pass "&priv" which is
an address in the stack and so it will lead to memory corruption when
the imx_sc_key_action() function is called. Remove the &.
Fixes: 768062fd12 ("Input: imx_sc_key - use devm_add_action_or_reset() to handle all cleanups")
