smb: client: fix incomplete backport in cfids_invalidation_worker()
The previous commit bdb596ceb4b7 ("smb: client: fix potential UAF in
smb2_close_cached_fid()") was an incomplete backport and missed one
kref_put() call in cfids_invalidation_worker() that should have been
converted to close_cached_dir().
On PF passthrough environment, after hibernate and then resume, coralgemm
will cause gpu page fault.
Mode1 reset happens during hibernate, but partition mode is not restored
on resume, register mmCP_HYP_XCP_CTL and mmCP_PSP_XCP_CTL is not right
after resume. When CP access the MQD BO, wrong stride size is used,
this will cause out of bound access on the MQD BO, resulting page fault.
The fix is to ensure gfx_v9_4_3_switch_compute_partition() is called
when resume from a hibernation.
KFD resume is called separately during a reset recovery or resume from
suspend sequence. Hence it's not required to be called as part of
partition switch.

The help message incorrectly listed '-t' as the short option for
--threads, but the actual getopt_long configuration uses '-e'.
This mismatch can confuse users and lead to incorrect command-line
usage. This patch updates the usage string to correctly show:
"-e, --threads NRTHR"
to match the implementation.
Note: checkpatch.pl reports a false-positive spelling warning on
'Run', which is intentional.

Since 8b3a087f7f65 ("ALSA: usb-audio: Unify virtual type units type to

When a zero ASCE is passed to the __ptep_rdp() inline assembly, the
generated instruction should have the R3 field of the instruction set to
zero. However the inline assembly is written incorrectly: for such cases a
zero is loaded into a register allocated by the compiler and this register
is then used by the instruction.
This means that selected TLB entries may not be flushed since the specified
ASCE does not match the one which was used when the selected TLB entries
were created.
Fix this by removing the asce and opt parameters of __ptep_rdp(), since
all callers always pass zero, and use a hard-coded register zero for
the R3 field.

relies on them for anything, and if the VMM wants to mess up

ALSA: usb-audio: Fix missing unlock at error path of maxpacksize check
The recent backport of the upstream commit 05a1fc5efdd8 ("ALSA:
usb-audio: Fix potential overflow of PCM transfer buffer") on the
older stable kernels like 6.12.y was broken since it doesn't consider
the mutex unlock, where the upstream code manages with guard().
In the older code, we still need an explicit unlock.
This is a fix that corrects the error path, applied only on old stable

When a netdev issues a RX async resync request for a TLS connection,
the TLS module handles it by logging record headers and attempting to
match them to the tcp_sn provided by the device. If a match is found,
the TLS module approves the tcp_sn for resynchronization.
While waiting for a device response, the TLS module also increments
rcd_delta each time a new TLS record is received, tracking the distance
from the original resync request.
However, if the device response is delayed or fails (e.g due to
unstable connection and device getting out of tracking, hardware
errors, resource exhaustion etc.), the TLS module keeps logging and
incrementing, which can lead to a WARN() when rcd_delta exceeds the
threshold.
To address this, introduce tls_offload_rx_resync_async_request_cancel()
to explicitly cancel resync requests when a device response failure is
detected. Call this helper also as a final safeguard when rcd_delta
crosses its threshold, as reaching this point implies that earlier
cancellation did not occur.
Update tls_offload_rx_resync_async_request_start() and
tls_offload_rx_resync_async_request_end() to get a struct
tls_offload_resync_async parameter directly, rather than
extracting it from struct sock.
This change aligns the function signatures with the upcoming
tls_offload_rx_resync_async_request_cancel() helper, which
will be introduced in a subsequent patch.
In bareudp.sh, this script uses /bin/sh and it will load another lib.sh
BASH script at the very beginning.
But on some operating systems like Ubuntu, /bin/sh is actually pointed to
DASH, thus it will try to run BASH commands with DASH and consequently
leads to syntax issues:
# ./bareudp.sh: 4: ./lib.sh: Bad substitution
# ./bareudp.sh: 5: ./lib.sh: source: not found
# ./bareudp.sh: 24: ./lib.sh: Syntax error: "(" unexpected
Fix this by explicitly using BASH for bareudp.sh. This fixes test
execution failures on systems where /bin/sh is not BASH.
Fix this regression by making scsi_host_busy() check whether the SCSI

scsi_mq_setup_tags() calls are serialized. This is the case in the UFS

During connect(), acting on a signal/timeout by disconnecting an already
established socket leads to several issues:
1. connect() invoking vsock_transport_cancel_pkt() ->
virtio_transport_purge_skbs() may race with sendmsg() invoking
virtio_transport_get_credit(). This results in a permanently elevated
`vvs->bytes_unsent`. Which, in turn, confuses the SOCK_LINGER handling.
2. connect() resetting a connected socket's state may race with socket
being placed in a sockmap. A disconnected socket remaining in a sockmap
breaks sockmap's assumptions. And gives rise to WARNs.
3. connect() transitioning SS_CONNECTED -> SS_UNCONNECTED allows for a
transport change/drop after TCP_ESTABLISHED. Which poses a problem for
any simultaneous sendmsg() or connect() and may result in a
use-after-free/null-ptr-deref.
Do not disconnect socket on signal/timeout. Keep the logic for unconnected
sockets: they don't linger, can't be placed in a sockmap, are rejected by
sendmsg().
Add proper cleanup of ctx->source and fc->source to the
cifs_parse_mount_err error handler. This ensures that memory allocated
for the source strings is correctly freed on all error paths, matching
the cleanup already performed in the success path by
smb3_cleanup_fs_context_contents().
Pointers are also set to NULL after freeing to prevent potential
double-free issues.
This change fixes a memory leak originally detected by syzbot. The
leak occurred when processing Opt_source mount options if an error
happened after ctx->source and fc->source were successfully
allocated but before the function completed.
The specific leak sequence was:
1. ctx->source = smb3_fs_context_fullpath(ctx, '/') allocates memory
2. fc->source = kstrdup(ctx->source, GFP_KERNEL) allocates more memory
3. A subsequent error jumps to cifs_parse_mount_err
4. The old error handler freed passwords but not the source strings,
causing the memory to leak.
This issue was not addressed by commit e8c73eb7db0a ("cifs: client:
fix memory leak in smb3_fs_context_parse_param"), which only fixed
leaks from repeated fsconfig() calls but not this error path.

Miao Wang reported a bug of SO_PEEK_OFF on AF_UNIX SOCK_STREAM
socket.
The unexpected behaviour is triggered when the peek offset is
larger than the recv queue and the thread is unblocked by new
data.
Let's assume a socket which has "aaaa" in the recv queue and
the peek offset is 4.
First, unix_stream_read_generic() reads the offset 4 and skips
the skb(s) of "aaaa" with the code below:
skip = max(sk_peek_offset(sk, flags), 0); /* @skip is 4. */
do {
...
while (skip >= unix_skb_len(skb)) {
skip -= unix_skb_len(skb);
...
skb = skb_peek_next(skb, &sk->sk_receive_queue);
if (!skb)
goto again; /* @skip is 0. */
}
The thread jumps to the 'again' label and goes to sleep since
new data has not arrived yet.
Later, new data "bbbb" unblocks the thread, and the thread jumps
to the 'redo:' label to restart the entire process from the first
skb in the recv queue.
do {
...
redo:
...
last = skb = skb_peek(&sk->sk_receive_queue);
...
again:
if (skb == NULL) {
...
timeo = unix_stream_data_wait(sk, timeo, last,
last_len, freezable);
...
goto redo; /* @skip is 0 !! */
However, the peek offset is not reset in the path.
If the buffer size is 8, recv() will return "aaaabbbb" without
skipping any data, and the final offset will be 12 (the original
offset 4 + peeked skbs' length 8).
After sleeping in unix_stream_read_generic(), we have to fetch the
peek offset again.
Let's move the redo label before mutex_lock(&u->iolock).

This prevents removal of other valid mappings and ensures precise

The function devl_rate_nodes_destroy is documented to "Unset parent for
all rate objects". However, it was only calling the driver-specific
`rate_leaf_parent_set` or `rate_node_parent_set` ops and decrementing
the parent's refcount, without actually setting the
`devlink_rate->parent` pointer to NULL.
This leaves a dangling pointer in the `devlink_rate` struct, which cause
refcount error in netdevsim[1] and mlx5[2]. In addition, this is
inconsistent with the behavior of `devlink_nl_rate_parent_node_set`,
where the parent pointer is correctly cleared.
This patch fixes the issue by explicitly setting `devlink_rate->parent`
to NULL after notifying the driver, thus fulfilling the function's
documented behavior for all rate objects.

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):

isst_if_probe() uses pci_read_config_dword() that returns PCIBIOS_*
codes. The return code is returned from the probe function as is but
probe functions should return normal errnos. A proper implementation
can be found in drivers/leds/leds-ss4200.c.
Convert PCIBIOS_* return codes using pcibios_err_to_errno() into
normal errno before returning.
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.
The function 'mpc_rcvd_sweep_req(mpcginfo)' is called conditionally
from function 'ctcmpc_unpack_skb'. It frees passed mpcginfo.

Blktests test cases nvme/014, 057 and 058 fail occasionally due to a
lockdep WARN. As reported in the Closes tag URL, the WARN indicates that
a deadlock can happen due to the dependency among disk->open_mutex,
kblockd workqueue completion and partition_scan_work completion.
To avoid the lockdep WARN and the potential deadlock, cut the dependency
by running the partition_scan_work not by kblockd workqueue but by
nvme_wq.

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.

host1x_memory_context_alloc() does not take ownership of the PID so we

The WMI driver core only supports GUID strings containing only
uppercase characters, however the GUID string used by the
msi-wmi-platform driver contains a single lowercase character.
This prevents the WMI driver core from matching said driver to
its WMI device.
Fix this by turning the lowercase character into a uppercase
character. Also update the WMI driver development guide to warn
about this.
It turns out that the GUID used by the msi-wmi-platform driver
(ABBC0F60-8EA1-11D1-00A0-C90629100000) is not unique, but was instead
copied from the WIndows Driver Samples. This means that this driver
could load on devices from other manufacturers that also copied this
GUID, potentially causing hardware errors.
Prevent this by only loading on devices whitelisted via DMI. The DMI
matches where taken from the msi-ec driver.
Add a check to ensure locally generated packets (skb->sk != NULL) do

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.

[Why]
On DCN20 & DCN30, the 6th DPP's & HUBP's are powered on permanently and
cannot be power gated. Thus, when dpp_reset() is invoked for the DPP5,
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
double cursor in full screen with non-native scaling.
[How]
Force disable cursor on DPP5 on plane powerdown for ASICs w/ 6 DPPs/HUBPs.

In case of DSS corruption, the MPTCP protocol tries to avoid the subflow
reset if fallback is possible. Such corruptions happen in the receive
path; to ensure fallback is possible the stack additionally needs to
check for OoO data, otherwise the fallback will break the data stream.
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.

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
transfer are now having a longer timeout: 2 minutes.
The Fixes commit was making the connection longer, but still, the
default timeout would have stopped it after 1 minute, which might not be
enough in very slow environments.

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().

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_cleanup_rbuf() needs to know the last most recent, mptcp-level
rcv_wnd sent, and such information is tracked into the msk->old_wspace
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.

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.

nvme_fc_delete_assocation() waits for pending I/O to complete before
returning, and an error can cause ->ioerr_work to be queued after
cancel_work_sync() had been called. Move the call to cancel_work_sync() to
be after nvme_fc_delete_association() to ensure ->ioerr_work is not running
when the nvme_fc_ctrl object is freed. Otherwise the following can occur:
Now target is removed from nvme_fc_ctrl_free() which is the ctrl->ref
release handler. And even admin queue is unquiesced there, this way
is definitely wrong because the ctr->ref is grabbed when submitting
command.
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.

In the pegasus_notetaker driver, the pegasus_probe() function allocates
the URB transfer buffer using the wMaxPacketSize value from
the endpoint descriptor. An attacker can use a malicious USB descriptor
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.
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 &.

Commit b6bcbce33596 ("soc/tegra: pmc: Ensure power-domains are in a
known state") was introduced so that all power domains get initialized
to a known working state when booting and it does this by shutting them
down (including asserting resets and disabling clocks) before registering
each power domain with the genpd framework, leaving it to each driver to
later on power its needed domains.
This caused the Google Pixel C to hang when booting due to a workaround
in the DSI driver introduced in commit b22fd0b9639e ("drm/tegra: dsi:
Clear enable register if powered by bootloader") meant to handle the case
where the bootloader enabled the DSI hardware module. The workaround relies
on reading a hardware register to determine the current status and after b6bcbce33596 that now happens in a powered down state thus leading to
the boot hang.
Fix this by reverting b22fd0b9639e since currently we are guaranteed
that the hardware will be fully reset by the time we start enabling the
DSI module.

Correct RGMII delay application logic in lan937x_set_tune_adj().
The function was missing `data16 &= ~PORT_TUNE_ADJ` before setting the
new delay value. This caused the new value to be bitwise-OR'd with the
existing PORT_TUNE_ADJ field instead of replacing it.
For example, when setting the RGMII 2 TX delay on port 4, the
intended TUNE_ADJUST value of 0 (RGMII_2_TX_DELAY_2NS) was
incorrectly OR'd with the default 0x1B (from register value 0xDA3),
leaving the delay at the wrong setting.
This patch adds the missing mask to clear the field, ensuring the
correct delay value is written. Physical measurements on the RGMII TX
lines confirm the fix, showing the delay changing from ~1ns (before
change) to ~2ns.
While testing on i.MX 8MP showed this was within the platform's timing
tolerance, it did not match the intended hardware-characterized value.

Commit cf3fc037623c ("ata: libata-scsi: Fix ata_to_sense_error() status
handling") fixed ata_to_sense_error() to properly generate sense key
ABORTED COMMAND (without any additional sense code), instead of the
previous bogus sense key ILLEGAL REQUEST with the additional sense code
UNALIGNED WRITE COMMAND, for a failed command.
However, this broke suspend for Security locked drives (drives that have
Security enabled, and have not been Security unlocked by boot firmware).
The reason for this is that the SCSI disk driver, for the Synchronize
Cache command only, treats any sense data with sense key ILLEGAL REQUEST
as a successful command (regardless of ASC / ASCQ).
After commit cf3fc037623c ("ata: libata-scsi: Fix ata_to_sense_error()
status handling") the code that treats any sense data with sense key
ILLEGAL REQUEST as a successful command is no longer applicable, so the
command fails, which causes the system suspend to be aborted:
sd 1:0:0:0: PM: dpm_run_callback(): scsi_bus_suspend returns -5
sd 1:0:0:0: PM: failed to suspend async: error -5
PM: Some devices failed to suspend, or early wake event detected
To make suspend work once again, for a Security locked device only,
return sense data LOGICAL UNIT ACCESS NOT AUTHORIZED, the actual sense
data which a real SCSI device would have returned if locked.
The SCSI disk driver treats this sense data as a successful command.

The sockmap feature allows bpf syscall from userspace, or based

When the server has MPTCP enabled but the client sends a TCP SYN

Then, this subflow can be normally used by sockmap, which replaces the
native sk_prot with sockmap's custom sk_prot. The issue occurs when the
user executes accept::mptcp_stream_accept::mptcp_fallback_tcp_ops().
Here, it uses sk->sk_prot to compare with the native sk_prot, but this
is incorrect when sockmap is used, as we may incorrectly set
sk->sk_socket->ops.
This fix uses the more generic sk_family for the comparison instead.
Additionally, this also prevents a WARNING from occurring:
result from ./scripts/decode_stacktrace.sh:

Consider two scenarios:
1. When the server has MPTCP enabled and the client also requests MPTCP,
the sk passed to the BPF program is a subflow sk. Since subflows only
handle partial data, replacing their sk_prot is meaningless and will
cause traffic disruption.
2. When the server has MPTCP enabled but the client sends a TCP SYN
without MPTCP, subflow_syn_recv_sock() performs a fallback on the
subflow, replacing the subflow sk's sk_prot with the native sk_prot.
'''
subflow_ulp_fallback()
subflow_drop_ctx()
mptcp_subflow_ops_undo_override()
'''
Subsequently, accept::mptcp_stream_accept::mptcp_fallback_tcp_ops()
converts the subflow to plain TCP.
For the first case, we should prevent it from being combined with sockmap
by setting sk_prot->psock_update_sk_prot to NULL, which will be blocked by
sockmap's own flow.
For the second case, since subflow_syn_recv_sock() has already restored
sk_prot to native tcp_prot/tcpv6_prot, no further action is needed.
In systemd we're trying to switch the internal credentials setup logic
to new mount API [1], and I noticed fsconfig(FSCONFIG_CMD_RECONFIGURE)
consistently fails on tmpfs with noswap option. This can be trivially
reproduced with the following:
After some digging the culprit is shmem_reconfigure() rejecting
!(ctx->seen & SHMEM_SEEN_NOSWAP) && sbinfo->noswap, which is bogus
as ctx->seen serves as a mask for whether certain options are touched
at all. On top of that, noswap option doesn't use fsparam_flag_no,
hence it's not really possible to "reenable" swap to begin with.
Drop the check and redundant SHMEM_SEEN_NOSWAP flag.

The "req.start" and "req.len" variables are u64 values that come from the
user at the start of the function. We mask away the high 32 bits of
"req.len" so that's capped at U32_MAX but the "req.start" variable can go
up to U64_MAX which means that the addition can still integer overflow.
We've had reports from the field that some RK3588 Tiger have random
issues with eMMC errors.
Applying commit a28352cf2d2f ("mmc: sdhci-of-dwcmshc: Change
DLL_STRBIN_TAPNUM_DEFAULT to 0x4") didn't help and seemed to have made
things worse for our board.
Our HW department checked the eMMC lines and reported that they are too
long and don't look great so signal integrity is probably not the best.
Note that not all Tigers with the same eMMC chip have errors, so the
suspicion is that we're really on the edge in terms of signal integrity
and only a handful devices are failing. Additionally, we have RK3588
Jaguars with the same eMMC chip but the layout is different and we also
haven't received reports about those so far.
Lowering the max-frequency to 150MHz from 200MHz instead of simply
disabling HS400 was briefly tested and seem to work as well. We've
disabled HS400 downstream and haven't received reports since so we'll go
with that instead of lowering the max-frequency.
In commit 296602b8e5f7 ("arm64: dts: rockchip: Move RK3399 OPPs to dtsi
files for SoC variants"), everything shared between variants of RK3399
was put into rk3399-base.dtsi and the rest in variant-specific DTSI,
such as rk3399-t, rk3399-op1, rk3399, etc.
Therefore, the variant-specific DTSI should include rk3399-base.dtsi and
not another variant's DTSI.
rk3399-op1 wrongly includes rk3399 (a variant) DTSI instead of
rk3399-base DTSI, let's fix this oversight by including the intended
DTSI.
Fortunately, this had no impact on the resulting DTB since all nodes
were named the same and all node properties were overridden in
rk3399-op1.dtsi. This was checked by doing a checksum of rk3399-op1 DTBs
before and after this commit.
The vcc3v3_pcie20 fixed regulator powers the PCIe device-side 3.3V rail
for pcie2x1l2 via vpcie3v3-supply. The DTS mistakenly set its
regulator-min/max-microvolt to 1800000 (1.8 V). Correct both to 3300000
(3.3 V) to match the rail name, the PCIe/M.2 power requirement, and the
actual hardware wiring on Orange Pi 5.
Page 13 of the PineTab2 v2 schematic dd 20230417 shows VCCIO4's power

VCCA1V8_PMU, so fix the PineTab2 dtsi to reflect that.
Based on available evidence, the USB ID 4c4a:4155 used by multiple
devices has been attributed to Jieli. The commit 1a8953f4f774

functionality. Added checks for manufacturer and serial number to
maintain microphone compatibility, enabling both devices to function
properly.
There is a race condition between timer_shutdown_sync() and timer
expiration that can lead to hitting a WARN_ON in expire_timers().
The issue occurs when timer_shutdown_sync() clears the timer function
to NULL while the timer is still running on another CPU. The race
scenario looks like this:
CPU0 CPU1
<SOFTIRQ>
lock_timer_base()
expire_timers()
base->running_timer = timer;
unlock_timer_base()
[call_timer_fn enter]
mod_timer()
...
timer_shutdown_sync()
lock_timer_base()
// For now, will not detach the timer but only clear its function to NULL
if (base->running_timer != timer)
ret = detach_if_pending(timer, base, true);
if (shutdown)
timer->function = NULL;
unlock_timer_base()
[call_timer_fn exit]
lock_timer_base()
base->running_timer = NULL;
unlock_timer_base()
...
// Now timer is pending while its function set to NULL.
// next timer trigger
<SOFTIRQ>
expire_timers()
WARN_ON_ONCE(!fn) // hit
...
lock_timer_base()
// Now timer will detach
if (base->running_timer != timer)
ret = detach_if_pending(timer, base, true);
if (shutdown)
timer->function = NULL;
unlock_timer_base()
The problem is that timer_shutdown_sync() clears the timer function
regardless of whether the timer is currently running. This can leave a
pending timer with a NULL function pointer, which triggers the
WARN_ON_ONCE(!fn) check in expire_timers().
Fix this by only clearing the timer function when actually detaching the
timer. If the timer is running, leave the function pointer intact, which is
safe because the timer will be properly detached when it finishes running.
