[ Upstream commit 98c0cc48e27e9d269a3e4db2acd72b486c88ec77 ]
policy_unpack_test fails on big endian systems because data byte order
is expected to be little endian but is generated in host byte order.
This results in test failures such as:
# policy_unpack_test_unpack_array_with_null_name: EXPECTATION FAILED at security/apparmor/policy_unpack_test.c:150
Expected array_size == (u16)16, but
array_size == 4096 (0x1000)
(u16)16 == 16 (0x10)
# policy_unpack_test_unpack_array_with_null_name: pass:0 fail:1 skip:0 total:1
not ok 3 policy_unpack_test_unpack_array_with_null_name
# policy_unpack_test_unpack_array_with_name: EXPECTATION FAILED at security/apparmor/policy_unpack_test.c:164
Expected array_size == (u16)16, but

(u16)16 == 16 (0x10)
# policy_unpack_test_unpack_array_with_name: pass:0 fail:1 skip:0 total:1
Add the missing endianness conversions when generating test data.

[ Upstream commit 919ddf8336f0b84c0453bac583808c9f165a85c2 ]
aac_probe_one() calls hardware-specific init functions through the
aac_driver_ident::init pointer, all of which eventually call down to
aac_init_adapter().
If aac_init_adapter() fails after allocating memory for aac_dev::queues,
it frees the memory but does not clear that member.
After the hardware-specific init function returns an error,
aac_probe_one() goes down an error path that frees the memory pointed to
by aac_dev::queues, resulting.in a double-free.

commit 6c3fc0b1c3d073bd6fc3bf43dbd0e64240537464 upstream.
A large tx latency issue was discovered during testing when only QBV was
enabled. The issue occurs because gtxoffset was not set when QBV is
active, it was only set when launch time is active.
The patch "igc: Correct the launchtime offset" only sets gtxoffset when
the launchtime_enable field is set by the user. Enabling launchtime_enable
ultimately sets the register IGC_TXQCTL_QUEUE_MODE_LAUNCHT (referred to as
LaunchT in the SW user manual).
Section 7.5.2.6 of the IGC i225/6 SW User Manual Rev 1.2.4 states:
"The latency between transmission scheduling (launch time) and the
time the packet is transmitted to the network is listed in Table 7-61."
However, the patch misinterprets the phrase "launch time" in that section
by assuming it specifically refers to the LaunchT register, whereas it
actually denotes the generic term for when a packet is released from the
internal buffer to the MAC transmit logic.
This launch time, as per that section, also implicitly refers to the QBV
gate open time, where a packet waits in the buffer for the QBV gate to
open. Therefore, latency applies whenever QBV is in use. TSN features such
as QBU and QAV reuse QBV, making the latency universal to TSN features.
Discussed with i226 HW owner (Shalev, Avi) and we were in agreement that
the term "launch time" used in Section 7.5.2.6 is not clear and can be
easily misinterpreted. Avi will update this section to:
"When TQAVCTRL.TRANSMIT_MODE = TSN, the latency between transmission
scheduling and the time the packet is transmitted to the network is listed
in Table 7-61."
Fix this issue by using igc_tsn_is_tx_mode_in_tsn() as a condition to
write to gtxoffset, aligning with the newly updated SW User Manual.
Tested:
1. Enrol taprio on talker board
base-time 0
cycle-time 1000000
flags 0x2
index 0 cmd S gatemask 0x1 interval1
index 0 cmd S gatemask 0x1 interval2
Note:
interval1 = interval for a 64 bytes packet to go through
interval2 = cycle-time - interval1
2. Take tcpdump on listener board
3. Use udp tai app on talker to send packets to listener
4. Check the timestamp on listener via wireshark
Test Result:
100 Mbps: 113 ~193 ns
1000 Mbps: 52 ~ 84 ns
2500 Mbps: 95 ~ 223 ns
Note that the test result is similar to the patch "igc: Correct the
launchtime offset".

commit 0afeaeb5dae86aceded0d5f0c3a54d27858c0c6f upstream.
Following the "igc: Fix TX Hang issue when QBV Gate is close" changes,
remaining issues with the reset adapter logic in igc_tsn_offload_apply()
have been observed:
1. The reset adapter logics for i225 and i226 differ, although they should
be the same according to the guidelines in I225/6 HW Design Section
7.5.2.1 on software initialization during tx mode changes.
2. The i225 resets adapter every time, even though tx mode doesn't change.
This occurs solely based on the condition igc_is_device_id_i225() when
calling schedule_work().
3. i226 doesn't reset adapter for tsn->legacy tx mode changes. It only
resets adapter for legacy->tsn tx mode transitions.
4. qbv_count introduced in the patch is actually not needed; in this
context, a non-zero value of qbv_count is used to indicate if tx mode
was unconditionally set to tsn in igc_tsn_enable_offload(). This could
be replaced by checking the existing register
IGC_TQAVCTRL_TRANSMIT_MODE_TSN bit.
This patch resolves all issues and enters schedule_work() to reset the
adapter only when changing tx mode. It also removes reliance on qbv_count.
qbv_count field will be removed in a future patch.
Test ran:
1. Verify reset adapter behaviour in i225/6:
a) Enrol a new GCL
Reset adapter observed (tx mode change legacy->tsn)
b) Enrol a new GCL without deleting qdisc
No reset adapter observed (tx mode remain tsn->tsn)
c) Delete qdisc
Reset adapter observed (tx mode change tsn->legacy)
2. Tested scenario from "igc: Fix TX Hang issue when QBV Gate is closed"
to confirm it remains resolved.

commit 687d6bccb28238fcfa65f7c1badfdfeac498c428 upstream.
Lanes can use other lanes' reference clocks, as determined by refclk.
Use refclk to determine the clock to enable/disable instead of always
using the lane's own reference clock. This ensures the clock selected in
xpsgtr_configure_pll is the one enabled.
For the other half of the equation, always program REF_CLK_SEL even when
we are selecting the lane's own clock. This ensures that Linux's idea of
the reference clock matches the hardware. We use the "local" clock mux
for this instead of going through the ref clock network.

commit ddfcfeba891064b88bb844208b43bef2ef970f0c upstream.
The probe function never performs any paltform device allocation, thus
error path "undo_platform_dev_alloc" is entirely bogus. It drops the
reference count from the platform device being probed. If error path is
triggered, this will lead to unbalanced device reference counts and
premature release of device resources, thus possible use-after-free when
releasing remaining devm-managed resources.

commit 14e497183df28c006603cc67fd3797a537eef7b9 upstream.
This commit addresses an issue where the USB core could access an
invalid event buffer address during runtime suspend, potentially causing
SMMU faults and other memory issues in Exynos platforms. The problem
arises from the following sequence.
1. In dwc3_gadget_suspend, there is a chance of a timeout when
moving the USB core to the halt state after clearing the
run/stop bit by software.
2. In dwc3_core_exit, the event buffer is cleared regardless of
the USB core's status, which may lead to an SMMU faults and
other memory issues. if the USB core tries to access the event
buffer address.
To prevent this hardware quirk on Exynos platforms, this commit ensures
that the event buffer address is not cleared by software when the USB
core is active during runtime suspend by checking its status before
clearing the buffer address.

commit f9bb896eab221618927ae6a2f1d566567999839d upstream.
Linux does not write into cmd-db region. This region of memory is write
protected by XPU. XPU may sometime falsely detect clean cache eviction
as "write" into the write protected region leading to secure interrupt
which causes an endless loop somewhere in Trust Zone.
The only reason it is working right now is because Qualcomm Hypervisor
maps the same region as Non-Cacheable memory in Stage 2 translation
tables. The issue manifests if we want to use another hypervisor (like
Xen or KVM), which does not know anything about those specific mappings.
Changing the mapping of cmd-db memory from MEMREMAP_WB to MEMREMAP_WT/WC
removes dependency on correct mappings in Stage 2 tables. This patch
fixes the issue by updating the mapping to MEMREMAP_WC.
I tested this on SA8155P with Xen.

[ Upstream commit febccb39255f9df35527b88c953b2e0deae50e53 ]
In case of im_protocols value is 1 and tm_protocols value is 0 this
combination successfully passes the check
'if (!im_protocols && !tm_protocols)' in the nfc_start_poll().
But then after pn533_poll_create_mod_list() call in pn533_start_poll()
poll mod list will remain empty and dev->poll_mod_count will remain 0
which lead to division by zero.
Normally no im protocol has value 1 in the mask, so this combination is
not expected by driver. But these protocol values actually come from
userspace via Netlink interface (NFC_CMD_START_POLL operation). So a
broken or malicious program may pass a message containing a "bad"
combination of protocol parameter values so that dev->poll_mod_count
is not incremented inside pn533_poll_create_mod_list(), thus leading
to division by zero.
Call trace looks like:
nfc_genl_start_poll()
nfc_start_poll()
->start_poll()
pn533_start_poll()
Add poll mod list filling check.

[ Upstream commit 3a0504d54b3b57f0d7bf3d9184a00c9f8887f6d7 ]
sctp_sf_do_5_2_4_dupcook() currently calls security_sctp_assoc_request()
on new_asoc, but as it turns out, this association is always discarded
and the LSM labels never get into the final association (asoc).
This can be reproduced by having two SCTP endpoints try to initiate an
association with each other at approximately the same time and then peel
off the association into a new socket, which exposes the unitialized
labels and triggers SELinux denials.
Fix it by calling security_sctp_assoc_request() on asoc instead of
new_asoc. Xin Long also suggested limit calling the hook only to cases
A, B, and D, since in cases C and E the COOKIE ECHO chunk is discarded
and the association doesn't enter the ESTABLISHED state, so rectify that
as well.
One related caveat with SELinux and peer labeling: When an SCTP
connection is set up simultaneously in this way, we will end up with an
association that is initialized with security_sctp_assoc_request() on
both sides, so the MLS component of the security context of the
association will get swapped between the peers, instead of just one side
setting it to the other's MLS component. However, at that point
security_sctp_assoc_request() had already been called on both sides in
sctp_sf_do_unexpected_init() (on a temporary association) and thus if
the exchange didn't fail before due to MLS, it won't fail now either
(most likely both endpoints have the same MLS range).
Tested by:

- selinux-testsuite (https://github.com/SELinuxProject/selinux-testsuite/)
- sctp-tests (https://github.com/sctp/sctp-tests) - no tests failed
that wouldn't fail also without the patch applied

freed from the active slave after xfrm state is deleted. The netdev
used to invoke xdo_dev_state_free callback, is saved in the xfrm state

it from being freed, acquire netdev reference before leaving RCU

Subtract network offset to skb->len before performing IPv4 header sanity

Jorge Ortiz says:
When small UDP packets (< 4 bytes payload) are sent from eth0,
`meta l4proto udp` condition is not met because `NFT_PKTINFO_L4PROTO` is
not set. This happens because there is a comparison that checks if the
transport header offset exceeds the total length. This comparison does
not take into account the fact that the skb network offset might be
non-zero in egress mode (e.g., 14 bytes for Ethernet header).

These three implementations of map_pages() all succeed if a mapping is
requested with no read or write. Since they return back to __iommu_map()
leaving the mapped output as 0 it triggers an infinite loop. Therefore
nothing is using no-access protection bits.
Further, VFIO and iommufd rely on iommu_iova_to_phys() to get back PFNs
stored by map, if iommu_map() succeeds but iommu_iova_to_phys() fails that
will create serious bugs.
Thus remove this never used "nothing to do" concept and just fail map
immediately.

[ Upstream commit d04b21bfa1c50a2ade4816cab6fdc91827b346b1 ]
Currently in case of the DEV_TO_MEM or MEM_TO_DEV DMA transfers the memory
data width (single transfer width) is determined based on the buffer
length, buffer base address or DMA master-channel max address width
capability. It isn't enough in case of the channel disabling prior the
block transfer is finished. Here is what DW AHB DMA IP-core databook says
regarding the port suspension (DMA-transfer pause) implementation in the
controller:
"When CTLx.SRC_TR_WIDTH < CTLx.DST_TR_WIDTH and the CFGx.CH_SUSP bit is
high, the CFGx.FIFO_EMPTY is asserted once the contents of the FIFO do not
permit a single word of CTLx.DST_TR_WIDTH to be formed. However, there may
still be data in the channel FIFO, but not enough to form a single
transfer of CTLx.DST_TR_WIDTH. In this scenario, once the channel is
disabled, the remaining data in the channel FIFO is not transferred to the
destination peripheral."
So in case if the port gets to be suspended and then disabled it's
possible to have the data silently discarded even though the controller
reported that FIFO is empty and the CTLx.BLOCK_TS indicated the dropped
data already received from the source device. This looks as if the data
somehow got lost on a way from the peripheral device to memory and causes
problems for instance in the DW APB UART driver, which pauses and disables
the DMA-transfer as soon as the recv data timeout happens. Here is the way
it looks:
Memory <------- DMA FIFO <------ UART FIFO <---------------- UART
DST_TR_WIDTH -+--------| | |
| | | | No more data
Current lvl -+--------| |---------+- DMA-burst lvl
| | |---------+- Leftover data
| | |---------+- SRC_TR_WIDTH
-+--------+-------+---------+
In the example above: no more data is getting received over the UART port
and BLOCK_TS is not even close to be fully received; some data is left in
the UART FIFO, but not enough to perform a bursted DMA-xfer to the DMA
FIFO; some data is left in the DMA FIFO, but not enough to be passed
further to the system memory in a single transfer. In this situation the
8250 UART driver catches the recv timeout interrupt, pauses the
DMA-transfer and terminates it completely, after which the IRQ handler
manually fetches the leftover data from the UART FIFO into the
recv-buffer. But since the DMA-channel has been disabled with the data
left in the DMA FIFO, that data will be just discarded and the recv-buffer
will have a gap of the "current lvl" size in the recv-buffer at the tail
of the lately received data portion. So the data will be lost just due to
the misconfigured DMA transfer.
Note this is only relevant for the case of the transfer suspension and
_disabling_. No problem will happen if the transfer will be re-enabled
afterwards or the block transfer is fully completed. In the later case the
"FIFO flush mode" will be executed at the transfer final stage in order to
push out the data left in the DMA FIFO.
In order to fix the denoted problem the DW AHB DMA-engine driver needs to
make sure that the _bursted_ source transfer width is greater or equal to
the single destination transfer (note the HW databook describes more
strict constraint than actually required). Since the peripheral-device
side is prescribed by the client driver logic, the memory-side can be only
used for that. The solution can be easily implemented for the DEV_TO_MEM
transfers just by adjusting the memory-channel address width. Sadly it's
not that easy for the MEM_TO_DEV transfers since the mem-to-dma burst size
is normally dynamically determined by the controller. So the only thing
that can be done is to make sure that memory-side address width is greater
than the peripheral device address width.

[ Upstream commit b336268dde75cb09bd795cb24893d52152a9191f ]
Currently the src_addr_width and dst_addr_width fields of the
dma_slave_config structure are mapped to the CTLx.SRC_TR_WIDTH and
CTLx.DST_TR_WIDTH fields of the peripheral bus side in order to have the
properly aligned data passed to the target device. It's done just by
converting the passed peripheral bus width to the encoded value using the
__ffs() function. This implementation has several problematic sides:
1. __ffs() is undefined if no bit exist in the passed value. Thus if the
specified addr-width is DMA_SLAVE_BUSWIDTH_UNDEFINED, __ffs() may return
unexpected value depending on the platform-specific implementation.
2. DW AHB DMA-engine permits having the power-of-2 transfer width limited
by the DMAH_Mk_HDATA_WIDTH IP-core synthesize parameter. Specifying
bus-width out of that constraints scope will definitely cause unexpected
result since the destination reg will be only partly touched than the
client driver implied.
Let's fix all of that by adding the peripheral bus width verification
method and calling it in dwc_config() which is supposed to be executed
before preparing any transfer. The new method will make sure that the
passed source or destination address width is valid and if undefined then
the driver will just fallback to the 1-byte width transfer.

commit ab8d66d132bc8f1992d3eb6cab8d32dda6733c84 upstream.
Two bitmasks in 'struct sdw_slave_prop' - 'source_ports' and
'sink_ports' - define which ports to program in
sdw_program_slave_port_params(). The masks are used to get the
appropriate data port properties ('struct sdw_get_slave_dpn_prop') from
an array.
Bitmasks can be non-continuous or can start from index different than 0,
thus when looking for matching port property for given port, we must
iterate over mask bits, not from 0 up to number of ports.
This fixes allocation and programming slave ports, when a source or sink
masks start from further index.

pin until one succeeds. For PULL_PU_PD_RSEL_TYPE pins, before the
breaking commit, mtk_pinconf_bias_set_rsel() would be called first to
try and set the RSEL value (as well as PU and PD), and if that failed,
the only other valid option was that bias-disable was specified, which
would then be handled by calling mtk_pinconf_bias_set_pu_pd() and
disabling both PU and PD.
The breaking commit misunderstood this logic and added an early "return
0" in mtk_pinconf_bias_set_rsel(). The result was that in the
bias-disable case, the bias was left unchanged, since by returning
success, mtk_pinconf_bias_set_combo() no longer tried calling
mtk_pinconf_bias_set_pu_pd() to disable the bias.
Since the logic for configuring bias-disable on PULL_PU_PD_RSEL_TYPE
pins required mtk_pinconf_bias_set_rsel() to fail first, in that case,
an error was printed to the log, eg:
mt8195-pinctrl 10005000.pinctrl: Not support rsel value 0 Ohm for pin = 29 (GPIO29)
This is what the breaking commit actually got rid of, and likely part of
the reason why that commit was thought to be fixing functionality, while
in reality it was breaking it.
Instead of simply reverting that commit, restore the functionality but
in a way that avoids the error from being printed and makes the code
less confusing:
* Return 0 explicitly if a bias method was successful
* Introduce an extra function mtk_pinconf_bias_set_pu_pd_rsel() that
calls both mtk_pinconf_bias_set_rsel() (only if needed) and
mtk_pinconf_bias_set_pu_pd()
* And analogously for the corresponding getters

[ Upstream commit a42db293e5983aa1508d12644f23d73f0553b32c ]
When ACP is not powered on by default, acp power on sequence explicitly
invoked by programming pgfsm control mask. The existing implementation
checks the same PGFSM status mask and programs the same PGFSM control mask
in all ACP variants which breaks acp power on sequence for ACP6.0 and
ACP6.3 variants. So to fix this issue, update ACP pgfsm control mask and
status mask based on acp descriptor rev field, which will vary based on
acp variant.

[ Upstream commit 34af4554fb0ce164e2c4876683619eb1e23848d4 ]
To avoid issues with out of order cleanup, or ambiguity about when the
auto freed data is first instantiated, do it within the for loop definition.
The disadvantage is that the struct device_node *child variable creation
is not immediately obvious where this is used.
However, in many cases, if there is another definition of
struct device_node *child; the compiler / static analysers will notify us
that it is unused, or uninitialized.
Note that, in the vast majority of cases, the _available_ form should be
used and as code is converted to these scoped handers, we should confirm
that any cases that do not check for available have a good reason not
to.

[ Upstream commit 322ea3778965da72862cca2a0c50253aacf65fe6 ]
Adding the following warning ...
WARN_ON_ONCE(msk->pm.local_addr_used == 0)
... before decrementing the local_addr_used counter helped to find a bug
when running the "remove single address" subtest from the mptcp_join.sh
selftests.
Removing a 'signal' endpoint will trigger the removal of all subflows
linked to this endpoint via mptcp_pm_nl_rm_addr_or_subflow() with
rm_type == MPTCP_MIB_RMSUBFLOW. This will decrement the local_addr_used
counter, which is wrong in this case because this counter is linked to
'subflow' endpoints, and here it is a 'signal' endpoint that is being
removed.
Now, the counter is decremented, only if the ID is being used outside
of mptcp_pm_nl_rm_addr_or_subflow(), only for 'subflow' endpoints, and
if the ID is not 0 -- local_addr_used is not taking into account these
ones. This marking of the ID as being available, and the decrement is
done no matter if a subflow using this ID is currently available,
because the subflow could have been closed before.

[ Upstream commit f448451aa62d54be16acb0034223c17e0d12bc69 ]
This helper is confusing. It is in pm.c, but it is specific to the
in-kernel PM and it cannot be used by the userspace one. Also, it simply
calls one in-kernel specific function with the PM lock, while the
similar mptcp_pm_remove_addr() helper requires the PM lock.
What's left is the pr_debug(), which is not that useful, because a
similar one is present in the only function called by this helper:
mptcp_pm_nl_rm_subflow_received()
After these modifications, this helper can be marked as 'static', and
the lock can be taken only once in mptcp_pm_flush_addrs_and_subflows().
Note that it is not a bug fix, but it will help backporting the
following commits.
