Fixes for v6.6-rc5
- fix to not reset the PHY everytime we start link training but only
do it if link training fails. Without this, the PLL unlocked
interrupt fires causing "Unexpected DP AUX IRQ 0x01000000 when
not busy" spam in the logs since last 2-3 cycles
- correct the highest bank bit to match downstream device tree for
msm8998
- skip the video mode wait if the timing engine is not enabled. This
was introduced after pre_enable flag for DSI video mode panels
where we would end up waiting for the video mode done interrupt
even before enabling timing engine causing error spam and long
bootup times.
- check the correct return code of irq_of_parse_and_map() in DSI code
- avoid overflow issues in the dpu bandwidth calculation . This was
exposed for high resolution displays and a critical fix to avoid
atomic_check failure
- minor fix to add new lines in DP print messages.
- Fix to fail atomic_check() if the resolution exceeds max mdp clk.
This leads to underflow otherwise if we try to allow that frame.

workqueue_apply_unbound_cpumask()
Commit 5c0338c68706 ("workqueue: restore WQ_UNBOUND/max_active==1
to be ordered") enabled implicit ordered attribute to be added to
WQ_UNBOUND workqueues with max_active of 1. This prevented the changing
of attributes to these workqueues leading to fix commit 0a94efb5acbb
("workqueue: implicit ordered attribute should be overridable").
However, workqueue_apply_unbound_cpumask() was not updated at that time.
So sysfs changes to wq_unbound_cpumask has no effect on WQ_UNBOUND
workqueues with implicit ordered attribute. Since not all WQ_UNBOUND
workqueues are visible on sysfs, we are not able to make all the
necessary cpumask changes even if we iterates all the workqueue cpumasks
in sysfs and changing them one by one.
Fix this problem by applying the corresponding change made
to apply_workqueue_attrs_locked() in the fix commit to
workqueue_apply_unbound_cpumask().

ftrace creates entries for each syscall in the tracefs but has failed
since commit 08d0ce30e0e4 ("riscv: Implement syscall wrappers") which
prefixes all riscv syscalls with __riscv_.
So fix this by implementing arch_syscall_match_sym_name() which allows us
to ignore this prefix.
And also ignore compat syscalls like x86/arm64 by implementing
arch_trace_is_compat_syscall().

[ 0.000000] Failed to add a Crash kernel resource at 177e00000
The crashkernel memory has been allocated successfully, whereas
it failed to insert into iomem_resource. This is due to the
unique reserving logic in risc-v arch specific code, i.e.
crashk_res/crashk_low_res will be added into iomem_resource
later in init_resources(), which is not aligned with current
unified reserving logic in reserve_crashkernel_{generic,low}()
and therefore leads to the failure of crashkernel reservation.
Removing the arch specific code within #ifdef CONFIG_KEXEC_CORE
in init_resources() to fix above problem.

There are two duplicate `-O binary` flags when objcopying from vmlinux
to Image/xipImage.
RISC-V set `-O binary` flag in both OBJCOPYFLAGS in the top-level riscv
Makefile and OBJCOPYFLAGS_* in the boot/Makefile, and the objcopy cmd
in Kbuild would join them together.
The `-O binary` flag is only needed for objcopying Image, so remove the
OBJCOPYFLAGS in the top-level riscv Makefile.

Currently, the kfree() be used for pwq objects allocated with
kmem_cache_alloc() in alloc_and_link_pwqs(), this isn't wrong.
but usually, use "trace_kmem_cache_alloc/trace_kmem_cache_free"
to track memory allocation and free. this commit therefore use
kmem_cache_free() instead of kfree() in alloc_and_link_pwqs()
and also consistent with release of the pwq in rcu_free_pwq().

The alternative stack checking in get_sigframe introduced by the Vector
support is not needed and has a problem. It is not needed as we have
already validate it at the beginning of the function if we are already
on an altstack. If not, the size of an altstack is always validated at
its allocation stage with sigaltstack_size_valid().
Besides, we must only regard the size of an altstack if the handler of a
signal is registered with SA_ONSTACK. So, blindly checking overflow of
an altstack if sas_ss_size not equals to zero will check against wrong
signal handlers if only a subset of signals are registered with
SA_ONSTACK.

Sergei Trofimovich reported a regression [0] caused by commit a0ade8404c3b
("af_packet: Fix warning of fortified memcpy() in packet_getname().").
It introduced a flex array sll_addr_flex in struct sockaddr_ll as a
union-ed member with sll_addr to work around the fortified memcpy() check.
However, a userspace program uses a struct that has struct sockaddr_ll in
the middle, where a flex array is illegal to exist.

This makes the driver work with the new check in
v4l2_async_register_subdev() that was introduced recently in 6.6-rc1.
Without this change, probe fails with:
ov8858 1-0036: Detected OV8858 sensor, revision 0xb2
ov8858 1-0036: sub-device fwnode is an endpoint!
ov8858 1-0036: v4l2 async register subdev failed
ov8858: probe of 1-0036 failed with error -22
This also simplifies the driver a bit.

In ipu_bridge_get_ivsc_acpi_dev(), the "ivsc_adev" acpi_device pointer
from the outer loop is handed over to the caller, which takes proper
care of its reference count.
However, the "consumer" acpi_device pointer from the inner loop is lost,
without decrementing its reference count.
Fix this by adding the missing call to acpi_dev_put().

The big V4L2 async framework overhaul simplified linked lists used by the
V4L2 async framework. This affected a few drivers and it turns out a few
of those drivers rely on searching for entities in both async notifier's
waiting and done lists. Do that by separately traversing both.

Since the stream API is still experimental it is currently locked away
behind the internal, default disabled, v4l2_subdev_enable_streams_api flag.
Advertising V4L2_SUBDEV_CAP_STREAMS when the streams API is disabled
confuses userspace. E.g. it causes the following libcamera error:
ERROR SimplePipeline simple.cpp:1497 Failed to reset routes for

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.
This code was found with the help of Coccinelle, and audited and
fixed manually.

SMC_STAT_PAYLOAD_SUB(_smc_stats, _tech, key, _len, _rc) will calculate
wrong bucket positions for payloads of exactly 4096 bytes and
(1 << (m + 12)) bytes, with m == SMC_BUF_MAX - 1.
Intended bucket distribution:
Assume l == size of payload, m == SMC_BUF_MAX - 1.
Bucket 0 : 0 < l <= 2^13
Bucket n, 1 <= n <= m-1 : 2^(n+12) < l <= 2^(n+13)
Bucket m : l > 2^(m+12)
Current solution:
_pos = fls64((l) >> 13)
[...]
_pos = (_pos < m) ? ((l == 1 << (_pos + 12)) ? _pos - 1 : _pos) : m
For l == 4096, _pos == -1, but should be _pos == 0.
For l == (1 << (m + 12)), _pos == m, but should be _pos == m - 1.
In order to avoid special treatment of these corner cases, the
calculation is adjusted. The new solution first subtracts the length by
one, and then calculates the correct bucket by shifting accordingly,
i.e. _pos = fls64((l - 1) >> 13), l > 0.
This not only fixes the issues named above, but also makes the whole
bucket assignment easier to follow.
Same is done for SMC_STAT_RMB_SIZE_SUB(_smc_stats, _tech, k, _len),
where the calculation of the bucket position is similar to the one
named above.

When the execution order is (1)->(2)->(3), it will crash. Therefore, in

syzbot has found an uninit-value bug triggered by the dm9601 driver [1].
This error happens because the variable res is not updated if the call
to dm_read_shared_word returns an error. In this particular case -EPROTO
was returned and res stayed uninitialized.
This can be avoided by checking the return value of dm_read_shared_word
and propagating the error if the read operation failed.

A bitset without mask in a _SET request means we want exactly the bits in
the bitset to be set. This works correctly for compact format but when
verbose format is parsed, ethnl_update_bitset32_verbose() only sets the
bits present in the request bitset but does not clear the rest. The commit
6699170376ab fixes this issue by clearing the whole target bitmap before we
start iterating. The solution proposed brought an issue with the behavior
of the mod variable. As the bitset is always cleared the old val will
always differ to the new val.
Fix it by adding a new temporary variable which save the state of the old
bitmap.

Our current route lookups (mctp_route_lookup and mctp_route_lookup_null)
traverse the net's route list without the RCU read lock held. This means
the route lookup is subject to preemption, resulting in an potential
grace period expiry, and so an eventual kfree() while we still have the
route pointer.
Add the proper read-side critical section locks around the route
lookups, preventing premption and a possible parallel kfree.
The remaining net->mctp.routes accesses are already under a
rcu_read_lock, or protected by the RTNL for updates.
Based on an analysis from Sili Luo <rootlab@huawei.com>, where
introducing a delay in the route lookup could cause a UAF on
simultaneous sendmsg() and route deletion.

When functions called by the trampoline panic, the backtrace that is
printed stops at the trampoline, because the trampoline does not store
its caller's frame address (backchain) on stack; it also stores the
return address at a wrong location.

One of the first things that s390x kernel functions do is storing the
the caller's frame address (backchain) on stack. This makes unwinding
possible. The backchain is always stored at frame offset 152, which is
inside the 160-byte stack area, that the functions allocate for their
callees. The callees must preserve the backchain; the remaining 152
bytes they may use as they please.
Currently the trampoline uses all 160 bytes, clobbering the backchain.
This causes kernel panics when using __builtin_return_address() in
functions called by the trampoline.
Fix by reducing the usage of the caller-reserved stack area by 8 bytes
in the trampoline.

Pull xen fix from Juergen Gross:
"A fix for the xen events driver:
Closing of an event channel in the Linux kernel can result in a
deadlock. This happens when the close is being performed in parallel
to an unrelated Xen console action and the handling of a Xen console
interrupt in an unprivileged guest.
The closing of an event channel is e.g. triggered by removal of a
paravirtual device on the other side. As this action will cause
console messages to be issued on the other side quite often, the
chance of triggering the deadlock is not negligible"

Static calls invocations aren't well supported from module __init and
__exit functions. Especially the static call from cleanup_trusted() led
to a crash on x86 kernel with CONFIG_DEBUG_VIRTUAL=y.
However, the usage of static call invocations for trusted_key_init()
and trusted_key_exit() don't add any value from either a performance or
security perspective. Hence switch to use indirect function calls instead.
Note here that although it will fix the current crash report, ultimately
the static call infrastructure should be fixed to either support its
future usage from module __init and __exit functions or not.

This reverts commit 5f521494cc73520ffac18ede0758883b9aedd018.
The patch breaks mounts with security mount options like
$ mount -o context=system_u:object_r:root_t:s0 /dev/sdX /mn
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdX, missing codepage or helper program, ...
We cannot reject all unknown options in btrfs_parse_subvol_options() as
intended, the security options can be present at this point and it's not
possible to enumerate them in a future proof way. This means unknown
mount options are silently accepted like before when the filesystem is
mounted with either -o subvol=/path or as followup mounts of the same
device.

When the SMC protocol is built into the kernel proper while ISM is
configured to be built as module, linking the kernel fails due to
unresolved dependencies out of net/smc/smc_ism.o to
ism_get_smcd_ops, ism_register_client, and ism_unregister_client
as reported via the linux-next test automation (see link).
This however is a bug introduced a while ago.
Correct the dependency list in ISM's and SMC's Kconfig to reflect the
dependencies that are actually inverted. With this you cannot build a
kernel with CONFIG_SMC=y and CONFIG_ISM=m. Either ISM needs to be 'y',
too - or a 'n'. That way, SMC can still be configured on non-s390
architectures that do not have (nor need) an ISM driver.

The sta_himax83102 panel sometimes shows abnormally flickering
horizontal lines. The front gate output will precharge the X point of
the next pole circuit before TP(TouchPanel Enable) term starts, and wait
until the end of the TP term to resume the CLK. For this reason, the X
point must be maintained during the TP term. In abnormal case, we
measured a slight leakage at point X. This because during the TP term,
the GPW does not fully pull the VGL low, causing the TFT to not be
closed tightly.
To fix this, we completely pull GPW to VGL before entering the TP term.
This will ensure that the TFT is closed tightly and prevent the abnormal
display.

When updating the SA, use the new update_pn flags instead of comparing the
new PN with the initial one.
Comparing the initial PN value with the new value will allow the user
to update the SA using the initial PN value as a parameter like this:
$ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \

Indicate next PN update using update_pn flag in macsec_context.
Offloaded MACsec implementations does not know whether or not the
MACSEC_SA_ATTR_PN attribute was passed for an SA update and assume
that next PN should always updated, but this is not always true.
The PN can be reset to its initial value using the following command:
$ ip macsec set macsec0 tx sa 0 off #octeontx2-pf case
Or, the update PN command will succeed even if the driver does not support
PN updates.
$ ip macsec set macsec0 tx sa 0 pn 1 on #mscc phy driver case
Comparing the initial PN with the new PN value is not a solution. When
the user updates the PN using its initial value the command will
succeed, even if the driver does not support it. Like this:
$ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \

Commit ff48b37802e5 ("scsi: Do not attempt to rescan suspended devices")
modified scsi_rescan_device() to avoid attempting rescanning a suspended
device. However, the modification added a check to verify that a SCSI
device is in the running state without checking if the device request
queue (in the case of block device) is also running, thus allowing the
exectuion of internal requests. Without checking the device request
queue, commit ff48b37802e5 fix is incomplete and deadlocks on resume can
still happen. Use blk_queue_pm_only() to check if the device request
queue allows executing commands in addition to checking the SCSI device
state.

fit3 protocol driver does not support accessing IDE control registers
(device control/altstatus). The DOS driver does not use these registers
either (as observed from DOSEMU trace). But the HW seems to be capable
of accessing these registers - I simply tried bit 3 and it works!
The control register is required to properly reset ATAPI devices or
they will be detected only once (after a power cycle).

Some parallel adapters (e.g. EXP Computer MC-1285B EPP Cable) return
bogus values when there's no master device present. This can cause
reset to fail, preventing the lone slave device (such as EXP Computer
CD-865) from working.
Add custom version of wait_after_reset that ignores master failure when
a slave device is present. The custom version is also needed because
the generic ata_sff_wait_after_reset uses direct port I/O for slave

Ifcfg config file support in NetworkManger is deprecated. This patch
provides support for the new keyfile config format for connection
profiles in NetworkManager. The patch modifies the hv_kvp_daemon code
to generate the new network configuration in keyfile
format(.ini-style format) along with a ifcfg format configuration.
The ifcfg format configuration is also retained to support easy
backward compatibility for distro vendors. These configurations are
stored in temp files which are further translated using the
hv_set_ifconfig.sh script. This script is implemented by individual
distros based on the network management commands supported.
For example, RHEL's implementation could be found here:
https://gitlab.com/redhat/centos-stream/src/hyperv-daemons/-/blob/c9s/hv_set_ifconfig.sh
Debian's implementation could be found here:
https://github.com/endlessm/linux/blob/master/debian/cloud-tools/hv_set_ifconfig
The next part of this support is to let the Distro vendors consume
these modified implementations to the new configuration format.

The verifier, as part of check_return_code(), verifies that async
callbacks such as from e.g. timers, will return 0. It does this by
correctly checking that R0->var_off is in tnum_const(0), which
effectively checks that it's in a range of 0. If this condition fails,
however, it prints an error message which says that the value should
have been in (0x0; 0x1). This results in possibly confusing output such
as the following in which an async callback returns 1:
At async callback the register R0 has value (0x1; 0x0) should have been in (0x0; 0x1)
The fix is easy -- we should just pass the tnum_const(0) as the correct
range to verbose_invalid_scalar(), which will then print the following:
At async callback the register R0 has value (0x1; 0x0) should have been in (0x0; 0x0)

Surfaces can be backed (i.e. stored in) memory objects (mob's) which
are created and managed by the userspace as GEM buffers. Surfaces
grab only a ttm reference which means that the gem object can
be deleted underneath us, especially in cases where prime buffer
export is used.
Make sure that all userspace surfaces which are backed by gem objects
hold a gem reference to make sure they're not deleted before vmw
surfaces are done with them, which fixes:

One PID may appear multiple times in a preloaded pidlist.
(Possibly due to PID recycling but we have reports of the same
task_struct appearing with different PIDs, thus possibly involving
transfer of PID via de_thread().)
Because v1 seq_file iterator uses PIDs as position, it leads to
a message:
> seq_file: buggy .next function kernfs_seq_next did not update position index
Conservative and quick fix consists of removing duplicates from `tasks`
file (as opposed to removing pidlists altogether). It doesn't affect
correctness (it's sufficient to show a PID once), performance impact
would be hidden by unconditional sorting of the pidlist already in place
(asymptotically).

taken from copy_from_sockptr() high enough to return SIZE_MAX by
struct_size(). The next PAGE_ALIGN(size) is such case will overflow
the size_t value and set it to 0. This will trigger WARN_ON_ONCE in
vmalloc_user() -> __vmalloc_node_range().
The issue is reproducible on 32-bit arm kernel.

The RISC-V BPF uses a5 for BPF return values, which are zero-extended,
whereas the RISC-V ABI uses a0 which is sign-extended. In other words,
a5 and a0 can differ, and are used in different context.
The BPF trampoline are used for both BPF programs, and regular kernel
functions.
Make sure that the RISC-V BPF trampoline saves, and restores both a0
and a5.

The RISC-V architecture does not expose sub-registers, and hold all
32-bit values in a sign-extended format [1] [2]:
| The compiler and calling convention maintain an invariant that all
| 32-bit values are held in a sign-extended format in 64-bit
| registers. Even 32-bit unsigned integers extend bit 31 into bits
| 63 through 32. Consequently, conversion between unsigned and
| signed 32-bit integers is a no-op, as is conversion from a signed
| 32-bit integer to a signed 64-bit integer.
While BPF, on the other hand, exposes sub-registers, and use
zero-extension (similar to arm64/x86).
This has led to some subtle bugs, where a BPF JITted program has not
sign-extended the a0 register (return value in RISC-V land), passed
the return value up the kernel, e.g.:
| int from_bpf(void);
|
| long foo(void)
| {
| return from_bpf();
| }
Here, a0 would be 0xffff_ffff, instead of the expected
0xffff_ffff_ffff_ffff.
Internally, the RISC-V JIT uses a5 as a dedicated register for BPF
return values.
Keep a5 zero-extended, but explicitly sign-extend a0 (which is used
outside BPF land). Now that a0 (RISC-V ABI) and a5 (BPF ABI) differs,
a0 is only moved to a5 for non-BPF native calls (BPF_PSEUDO_CALL).

irq1_edge_low_force_override[]
The TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q are 3 GPU variants of a TongFang
barebone design which is sold under various brand names.
The ACPI IRQ override for the keyboard IRQ must be used on these AMD Zen
laptops in order for the IRQ to work.
Adjust the pcspecialist_laptop[] DMI match table for this:
1. Drop the sys-vendor match from the existing PCSpecialist Elimina Pro 16
entry for the GM6BGEQ (RTX3050 GPU) model so that it will also match
the laptop when sold by other vendors such as hyperbook.pl.
2. Add board-name matches for the GM6BG5Q (RTX4050) and GM6B0Q (RTX4060)
models.
Note the .ident values of the dmi_system_id structs are left unset
since these are not used.

In this code "ret" is type long and "src_objlen" is unsigned int. The
problem is that on 32bit systems, when we do the comparison signed longs
are type promoted to unsigned int. So negative error codes from
do_splice_direct() are treated as success instead of failure.

Direct calls to ops->connect() can overwrite the address parameter when
used in conjunction with BPF SOCK_ADDR hooks. Recent changes to
kernel_connect() ensure that callers are insulated from such side
effects. This patch wraps the direct call to ops->connect() with
kernel_connect() to prevent unexpected changes to the address passed to
ceph_tcp_connect().
This change was originally part of a larger patch targeting the net tree
addressing all instances of unprotected calls to ops->connect()
throughout the kernel, but this change was split up into several patches
targeting various trees.

Before returning, function ceph_fname_to_usr() does a final IS_ERR() check
in 'dir':
if ((dir != fname->dir) && !IS_ERR(dir)) {...}
This check is unnecessary because, if the 'dir' variable has changed to
something other than 'fname->dir' (it's initial value), that error check has
been performed already and, if there was indeed an error, it would have
been returned immediately.
Besides, this useless IS_ERR() is also confusing static analysis tools.

When truncating the inode the MDS will acquire the xlock for the
ifile Locker, which will revoke the 'Frwsxl' caps from the clients.
But when the client just releases and flushes the 'Fw' caps to MDS,
for exmaple, and once the MDS receives the caps flushing msg it
just thought the revocation has finished. Then the MDS will continue
truncating the inode and then issued the truncate notification to
all the clients. While just before the clients receives the cap
flushing ack they receive the truncation notification, the clients
will detecte that the 'issued | dirty' is still holding the 'Fw'
caps.

Commit 9e70a5e109a4 ("printk: Add per-console suspended state")
removed console lock usage during resume and replaced it with
the clearly defined console_list_lock and srcu mechanisms.
However, the console lock usage had an important side-effect
of flushing the consoles. After its removal, consoles were no
longer flushed before checking their progress.
Add the console_lock/console_unlock dance to the beginning
of __pr_flush() to actually flush the consoles before checking
their progress. Also add comments to clarify this additional
usage of the console lock.
Note that console_unlock() does not guarantee flushing all messages
since the commit dbdda842fe96f89 ("printk: Add console owner and waiter

In unprivileged Xen guests event handling can cause a deadlock with
Xen console handling. The evtchn_rwlock and the hvc_lock are taken in
opposite sequence in __hvc_poll() and in Xen console IRQ handling.
Normally this is no problem, as the evtchn_rwlock is taken as a reader
in both paths, but as soon as an event channel is being closed, the
lock will be taken as a writer, which will cause read_lock() to block:
CPU0 CPU1 CPU2
(IRQ handling) (__hvc_poll()) (closing event channel)
read_lock(evtchn_rwlock)
spin_lock(hvc_lock)
write_lock(evtchn_rwlock)
[blocks]
spin_lock(hvc_lock)
[blocks]
read_lock(evtchn_rwlock)
[blocks due to writer waiting,
and not in_interrupt()]
This issue can be avoided by replacing evtchn_rwlock with RCU in
xen_free_irq(). Note that RCU is used only to delay freeing of the
irq_info memory. There is no RCU based dereferencing or replacement of
pointers involved.
In order to avoid potential races between removing the irq_info
reference and handling of interrupts, set the irq_info pointer to NULL
only when freeing its memory. The IRQ itself must be freed at that
time, too, as otherwise the same IRQ number could be allocated again
before handling of the old instance would have been finished.
This is XSA-441 / CVE-2023-34324.

In case of MDMA chaining, DMA is configured in Double-Buffer Mode (DBM)
with two periods, but if transfer has been prepared with _prep_slave_sg(),
the transfer is not marked cyclic (=!chan->desc->cyclic). However, as DBM
is activated for MDMA chaining, residue computation must take into account
cyclic constraints.
With only two periods in MDMA chaining, and no update due to Transfer
Complete interrupt masked, n_sg is always 0. If DMA current memory address
(depending on SxCR.CT and SxM0AR/SxM1AR) does not correspond, it means n_sg
should be increased.
Then, the residue of the current period is the one read from SxNDTR and
should not be overwritten with the full period length.

CRQA flag is set by hardware when the channel request become active and
the channel is enabled. It is cleared by hardware, when the channel request
is completed.
So when it is set, it means MDMA is transferring bytes.
This information is useful in case of STM32 DMA and MDMA chaining,
especially when the user pauses DMA before stopping it, to trig one last
MDMA transfer to get the latest bytes of the SRAM buffer to the
destination buffer.
STM32 DCMI driver can then use this to know if the last MDMA transfer in
case of chaining is done.

Current implementation relies on curr_hwdesc index. But to keep this index
up to date, Block Transfer interrupt (BTIE) has to be enabled.
If it is not, curr_hwdesc is not updated, and then residue is not reliable.
Rely on Link Address Register instead. And disable BTIE interrupt
in stm32_mdma_setup_xfer() because it is no more needed in case of
_prep_slave_sg() to maintain curr_hwdesc up to date.
It avoids extra interrupts and also ensures a reliable residue. These
improvements are required for STM32 DCMI camera capture use case, which
need STM32 DMA and MDMA chaining for good performance.

When one of the LAG interfaces is in switchdev mode, setting default rule

The interface on which switchdev is running has ice_set_rx_mode() blocked

Do not set netback interfaces (vifs) default TX queue size to the ring size.
The TX queue size is not related to the ring size, and using the ring size (32)
as the queue size can lead to packet drops. Note the TX side of the vif
interface in the netback domain is the one receiving packets to be injected
to the guest.
Do not explicitly set the TX queue length to any value when creating the
interface, and instead use the system default. Note that the queue length can
also be adjusted at runtime.

If of_clk_add_provider() fails in ca8210_register_ext_clock(),
it calls clk_unregister() to release priv->clk and returns an
error. However, the caller ca8210_probe() then calls ca8210_remove(),
where priv->clk is freed again in ca8210_unregister_ext_clock(). In
this case, a use-after-free may happen in the second time we call
clk_unregister().
Fix this by removing the first clk_unregister(). Also, priv->clk could
be an error code on failure of clk_register_fixed_rate(). Use
IS_ERR_OR_NULL to catch this case in ca8210_unregister_ext_clock().

Back in 2005, Kyle McMartin removed the 16-byte alignment for
ldcw semaphores on PA 2.0 machines (CONFIG_PA20). This broke
spinlocks on pre PA8800 processors. The main symptom was random
faults in mmap'd memory (e.g., gcc compilations, etc).
Unfortunately, the errata for this ldcw change is lost.
The issue is the 16-byte alignment required for ldcw semaphore
instructions can only be reduced to natural alignment when the
ldcw operation can be handled coherently in cache. Only PA8800
and PA8900 processors actually support doing the operation in
cache.
Aligning the spinlock dynamically adds two integer instructions
to each spinlock.
Tested on rp3440, c8000 and a500.

The RISC-V INTC local interrupts are per-HART (or per-CPU) so we
create INTC IRQ domain only for the INTC node belonging to the boot
HART. This means only the boot HART INTC node will be marked as
initialized and other INTC nodes won't be marked which results
downstream interrupt controllers (such as PLIC, IMSIC and APLIC
direct-mode) not being probed due to missing device suppliers.
To address this issue, we mark all INTC node for which we don't
create IRQ domain as initialized.

The GIC architecture specification defines a set of registers
for redistributors and ITSes that control the sharebility and
cacheability attributes of redistributors/ITSes initiator ports
on the interconnect (GICR_[V]PROPBASER, GICR_[V]PENDBASER,
GITS_BASER<n>).
Architecturally the GIC provides a means to drive shareability
and cacheability attributes signals and related IWB/OWB/ISH barriers
but it is not mandatory for designs to wire up the corresponding
interconnect signals that control the cacheability/shareability
of transactions.
Redistributors and ITSes interconnect ports can be connected to
non-coherent interconnects that are not able to manage the
shareability/cacheability attributes; this implicitly makes
the redistributors and ITSes non-coherent observers.
So far, the GIC driver on probe executes a write to "probe" for
the redistributors and ITSes registers shareability bitfields
by writing a value (ie InnerShareable - the shareability domain the
CPUs are in) and check it back to detect whether the value sticks or
not; this hinges on a GIC programming model behaviour that predates the
current specifications, that just define shareability bits as writeable
but do not guarantee that writing certain shareability values
enable the expected behaviour for the redistributors/ITSes
memory interconnect ports.
To enable non-coherent GIC designs, introduce the "dma-noncoherent"
device tree property to allow firmware to describe redistributors and
ITSes as non-coherent observers on the memory interconnect and use the
property to force the shareability attributes to be programmed into the
redistributors and ITSes registers through the GIC quirks mechanism.

Martin reported that on his local dev machine the test_tc_chain_mixed() fails as
"test_tc_chain_mixed:FAIL:seen_tc5 unexpected seen_tc5: actual 1 != expected 0"
and others occasionally, too.
However, when running in a more isolated setup (qemu in particular), it works fine
for him. The reason is that there is a small race-window where seen_tc* could turn
into true for various test cases when there is background traffic, e.g. after the
asserts they often get reset. In such case when subsequent detach takes place,
unrelated background traffic could have already flipped the bool to true beforehand.
Add a small helper tc_skel_reset_all_seen() to reset all bools before we do the ping
test. At this point, everything is set up as expected and therefore no race can occur.
All tc_{opts,links} tests continue to pass after this change.

The recently added tcx attachment extended the BPF UAPI for attaching and
detaching by a couple of fields. Those fields are currently only supported
for tcx, other types like cgroups and flow dissector silently ignore the
new fields except for the new flags.
This is problematic once we extend bpf_mprog to older attachment types, since
it's hard to figure out whether the syscall really was successful if the
kernel silently ignores non-zero values.
Explicitly reject non-zero fields relevant to bpf_mprog for attachment types
which don't use the latter yet.

into a subsequent bpf_mprog_attach() call as expected_revision. A BPF self-
test as part of this series has been added to assert this case.

While working on the ebpf-go [0] library integration for bpf_mprog and tcx,
Lorenz noticed that two subsequent BPF_PROG_QUERY requests currently fail. A
typical workflow is to first gather the bpf_mprog count without passing program/
link arrays, followed by the second request which contains the actual array
pointers.
The initial call populates count and revision fields. The second call gets
rejected due to a BPF_PROG_QUERY_LAST_FIELD bug which should point to
query.revision instead of query.link_attach_flags since the former is really
the last member.
It was not noticed in libbpf as bpf_prog_query_opts() always calls bpf(2) with
an on-stack bpf_attr that is memset() each time (and therefore query.revision
was reset to zero).

The ravb_stop() should call cancel_work_sync(). Otherwise,
ravb_tx_timeout_work() is possible to use the freed priv after
ravb_remove() was called like below:
CPU0 CPU1
ravb_tx_timeout()
ravb_remove()
unregister_netdev()
free_netdev(ndev)
// free priv
ravb_tx_timeout_work()
// use priv
unregister_netdev() will call .ndo_stop() so that ravb_stop() is
called. And, after phy_stop() is called, netif_carrier_off()
is also called. So that .ndo_tx_timeout() will not be called
after phy_stop().

Devlink health dump get callback should take devlink lock as any other
devlink callback. Otherwise, since devlink_mutex was removed, this
callback is not protected from a race of the reporter being destroyed
while handling the callback.
Add devlink lock to the callback and to any call for
devlink_health_do_dump(). This should be safe as non of the drivers dump
callback implementation takes devlink lock.
As devlink lock is added to any callback of dump, the reporter dump_lock
is now redundant and can be removed.

The DSU PMU allows monitoring performance events in the DSU cluster,
which is done by configuring and reading back values from the DSU PMU
system registers. However, for write-access to be allowed by ELs lower
than EL3, the EL3 firmware needs to update the setting on the ACTLR3_EL3
register, as it is disallowed by default.
That configuration is not done on the firmware used by the MT8195 SoC,
as a consequence, booting a MT8195-based machine like
mt8195-cherry-tomato-r2 with CONFIG_ARM_DSU_PMU enabled hangs the kernel
just as it writes to the CLUSTERPMOVSCLR_EL1 register, since the
instruction faults to EL3, and BL31 apparently just re-runs the
instruction over and over.
Mark the DSU PMU node in the Devicetree with status "fail", as the
machine doesn't have a suitable firmware to make use of it from the
kernel, and allowing its driver to probe would hang the kernel.

I am a top reviewer mainly for MediaTek SoC related patches in most
subsystems and I've also been upstreaming both improvements, fixes
and new drivers and devicetrees when required.
The MediaTek scene saw a generous increase in number of patches that
are sent to the lists every week, increasing the amount of required
efforts to maintain the MTK bits overall, and we will possibly see
even more of that.
For this reason, and also because of suggestions and encouragement
coming from the community, I'm stepping up to be a co-maintainer of
MediaTek SoCs support.

The 'msi' child node schema is missing constraints on additional properties.
It turns out it is incomplete and properties for it are documented in the
parent node by mistake. Move the reference to msi-controller.yaml and
the custom properties to the 'msi' node. Adding 'unevaluatedProperties'
ensures all the properties in the 'msi' node are documented.
With the schema corrected, a minimal interrupt controller node is needed
to properly decode the interrupt properties since the example has
multiple interrupt parents.

hidpp_connect_event() has *four* time-of-check vs time-of-use (TOCTOU)
races when it races with itself.
hidpp_connect_event() primarily runs from a workqueue but it also runs
on probe() and if a "device-connected" packet is received by the hw
when the thread running hidpp_connect_event() from probe() is waiting on
the hw, then a second thread running hidpp_connect_event() will be
started from the workqueue.
This opens the following races (note the below code is simplified):
1. Retrieving + printing the protocol (harmless race):
if (!hidpp->protocol_major) {
hidpp_root_get_protocol_version()
hidpp->protocol_major = response.rap.params[0];
}
We can actually see this race hit in the dmesg in the abrt output
attached to rhbz#2227968:
[ 3064.624215] logitech-hidpp-device 0003:046D:4071.0049: HID++ 4.5 device connected.
[ 3064.658184] logitech-hidpp-device 0003:046D:4071.0049: HID++ 4.5 device connected.
Testing with extra logging added has shown that after this the 2 threads
take turn grabbing the hw access mutex (send_mutex) so they ping-pong
through all the other TOCTOU cases managing to hit all of them:
2. Updating the name to the HIDPP name (harmless race):
if (hidpp->name == hdev->name) {
...
hidpp->name = new_name;
}
3. Initializing the power_supply class for the battery (problematic!):
hidpp_initialize_battery()
{
if (hidpp->battery.ps)
return 0;
probe_battery(); /* Blocks, threads take turns executing this */
hidpp->battery.desc.properties =
devm_kmemdup(dev, hidpp_battery_props, cnt, GFP_KERNEL);
hidpp->battery.ps =
devm_power_supply_register(&hidpp->hid_dev->dev,
&hidpp->battery.desc, cfg);
}
4. Creating delayed input_device (potentially problematic):
if (hidpp->delayed_input)
return;
hidpp->delayed_input = hidpp_allocate_input(hdev);
The really big problem here is 3. Hitting the race leads to the following
sequence:
hidpp->battery.desc.properties =
devm_kmemdup(dev, hidpp_battery_props, cnt, GFP_KERNEL);
hidpp->battery.ps =
devm_power_supply_register(&hidpp->hid_dev->dev,
&hidpp->battery.desc, cfg);
...
hidpp->battery.desc.properties =
devm_kmemdup(dev, hidpp_battery_props, cnt, GFP_KERNEL);
hidpp->battery.ps =
devm_power_supply_register(&hidpp->hid_dev->dev,
&hidpp->battery.desc, cfg);
So now we have registered 2 power supplies for the same battery,
which looks a bit weird from userspace's pov but this is not even
the really big problem.
Notice how:
1. This is all devm-maganaged
2. The hidpp->battery.desc struct is shared between the 2 power supplies
3. hidpp->battery.desc.properties points to the result from the second
devm_kmemdup()
This causes a use after free scenario on USB disconnect of the receiver:
1. The last registered power supply class device gets unregistered
2. The memory from the last devm_kmemdup() call gets freed,
hidpp->battery.desc.properties now points to freed memory
3. The first registered power supply class device gets unregistered,
this involves sending a remove uevent to userspace which invokes
power_supply_uevent() to fill the uevent data
4. power_supply_uevent() uses hidpp->battery.desc.properties which
now points to freed memory leading to backtraces like this one:

IMX93 A0 chip involve the internal q-channel handshake in LPCG and
CCM to automatically handle the Flex-CAN IPG STOP signal. Only after
FLEX-CAN enter stop mode then can support the self-wakeup feature.
But meet issue when do the continue system PM stress test. When config
the CAN as wakeup source, the first time after system suspend, any data
on CAN bus can wakeup the system, this is as expect. But the second time
when system suspend, data on CAN bus can't wakeup the system. If continue
this test, we find in odd time system enter suspend, CAN can wakeup the
system, but in even number system enter suspend, CAN can't wakeup the
system. IC find a bug in the auto stop mode logic, and can't fix it easily.
So for the new imx93 A1, IC drop the auto stop mode and involve the
GPR to support stop mode (used before). IC define a bit in GPR which can
trigger the IPG STOP signal to Flex-CAN, let it go into stop mode.
And NXP claim to drop IMX93 A0, and only support IMX93 A1. So this patch
remove the auto stop mode, and add flag FLEXCAN_QUIRK_SETUP_STOP_MODE_GPR
to imx93.

Upstream commit 717c6ec241b5 ("can: sja1000: Prevent overrun stalls with
a soft reset on Renesas SoCs") fixes an issue with Renesas own SJA1000
CAN controller reception: the Rx buffer is only 5 messages long, so when
the bus loaded (eg. a message every 50us), overrun may easily
happen. Upon an overrun situation, due to a possible internal crosstalk
situation, the controller enters a frozen state which only can be
unlocked with a soft reset (experimentally). The solution was to offload
a call to sja1000_start() in a threaded handler. This needs to happen in
process context as this operation requires to sleep. sja1000_start()
basically enters "reset mode", performs a proper software reset and
returns back into "normal mode".
Since this fix was introduced, we no longer observe any stalls in
reception. However it was sporadically observed that the transmit path
would now freeze. Further investigation blamed the fix mentioned above,
and especially the reset operation. Reproducing the reset in a loop
helped identifying what could possibly go wrong. The sja1000 is a single
Tx queue device, which leverages the netdev helpers to process one Tx
message at a time. The logic is: the queue is stopped, the message sent
to the transceiver, once properly transmitted the controller sets a
status bit which triggers an interrupt, in the interrupt handler the
transmission status is checked and the queue woken up. Unfortunately, if
an overrun happens, we might perform the soft reset precisely between
the transmission of the buffer to the transceiver and the advent of the
transmission status bit. We would then stop the transmission operation
without re-enabling the queue, leading to all further transmissions to
be ignored.
The reset interrupt can only happen while the device is "open", and
after a reset we anyway want to resume normal operations, no matter if a
packet to transmit got dropped in the process, so we shall wake up the
queue. Restarting the device and waking-up the queue is exactly what
sja1000_set_mode(CAN_MODE_START) does. In order to be consistent about
the queue state, we must acquire a lock both in the reset handler and in
the transmit path to ensure serialization of both operations. It turns
out, a lock is already held when entering the transmit path, so we can
just acquire/release it as well with the regular net helpers inside the
threaded interrupt handler and this way we should be safe. As the
reset handler might still be called after the transmission of a frame to
the transceiver but before it actually gets transmitted, we must ensure
we don't leak the skb, so we free it (the behavior is consistent, no
matter if there was an skb on the stack or not).

With patch [1], isotp_poll was updated to also queue the poller in the
so->wait queue, which is used for send state changes. Since the queue
now also contains polling tasks that are not interested in sending, the
queue fill state can no longer be used as an indication of send
readiness. As a consequence, nonblocking writes can lead to a race and
lock-up of the socket if there is a second task polling the socket in
parallel.
With this patch, isotp_sendmsg does not consult wq_has_sleepers but
instead tries to atomically set so->tx.state and waits on so->wait if it
is unable to do so. This behavior is in alignment with isotp_poll, which
also checks so->tx.state to determine send readiness.

commit d61491a51f7e ("net/sched: cls_u32: Replace one-element array
with flexible-array member") incorrecly replaced an instance of
`sizeof(*tp_c)` with `struct_size(tp_c, hlist->ht, 1)`. This results
in a an over-allocation of 8 bytes.
This change is wrong because `hlist` in `struct tc_u_common` is a
pointer:
net/sched/cls_u32.c:
struct tc_u_common {
struct tc_u_hnode __rcu *hlist;
void *ptr;
int refcnt;
struct idr handle_idr;
struct hlist_node hnode;
long knodes;
};
So, the use of `struct_size()` makes no sense: we don't need to allocate
any extra space for a flexible-array member. `sizeof(*tp_c)` is just fine.
So, `struct_size(tp_c, hlist->ht, 1)` translates to:
sizeof(*tp_c) + sizeof(tp_c->hlist->ht) ==
sizeof(struct tc_u_common) + sizeof(struct tc_u_knode *) ==
144 + 8 == 0x98 (byes)
^^^
|
unnecessary extra
allocation size
$ pahole -C tc_u_common net/sched/cls_u32.o
struct tc_u_common {
struct tc_u_hnode * hlist; /* 0 8 */
void * ptr; /* 8 8 */
int refcnt; /* 16 4 */
/* XXX 4 bytes hole, try to pack */
struct idr handle_idr; /* 24 96 */
/* --- cacheline 1 boundary (64 bytes) was 56 bytes ago --- */
struct hlist_node hnode; /* 120 16 */
/* --- cacheline 2 boundary (128 bytes) was 8 bytes ago --- */
long int knodes; /* 136 8 */
/* size: 144, cachelines: 3, members: 6 */
/* sum members: 140, holes: 1, sum holes: 4 */
/* last cacheline: 16 bytes */
};
And with `sizeof(*tp_c)`, we have:
sizeof(*tp_c) == sizeof(struct tc_u_common) == 144 == 0x90 (bytes)
which is the correct and original allocation size.
Fix this issue by replacing `struct_size(tp_c, hlist->ht, 1)` with
`sizeof(*tp_c)`, and avoid allocating 8 too many bytes.
The following difference in binary output is expected and reflects the
desired change:

PHYs via management frames
Besides the QCA8337 switch the Turris 1.x device has on it's MDIO bus
also Micron ethernet PHY (dedicated to the WAN port).
We've been experiencing a strange behavior of the WAN ethernet
interface, wherein the WAN PHY started timing out the MDIO accesses, for
example when the interface was brought down and then back up.
Bisecting led to commit 2cd548566384 ("net: dsa: qca8k: add support for
phy read/write with mgmt Ethernet"), which added support to access the
QCA8337 switch's internal PHYs via management ethernet frames.
Connecting the MDIO bus pins onto an oscilloscope, I was able to see
that the MDIO bus was active whenever a request to read/write an
internal PHY register was done via an management ethernet frame.
My theory is that when the switch core always communicates with the
internal PHYs via the MDIO bus, even when externally we request the
access via ethernet. This MDIO bus is the same one via which the switch
and internal PHYs are accessible to the board, and the board may have
other devices connected on this bus. An ASCII illustration may give more
insight:
+---------+

| | WAN PHY |
| +--| |

| | o--| ... | |
+----------------------------------+
When we send a request to read an internal PHY register via an ethernet
management frame via eth1, the switch core receives the ethernet frame
on port 0 and then communicates with the internal PHY via MDIO. At this
time, other potential devices, such as the WAN PHY on Turris 1.x, cannot
use the MDIO bus, since it may cause a bus conflict.
Fix this issue by locking the MDIO bus even when we are accessing the
PHY registers via ethernet management frames.

Commit c766e077d927 ("net: dsa: qca8k: convert to regmap read/write
API") introduced bulk read/write methods to qca8k's regmap.
The regmap bulk read/write methods get the register address in a buffer
passed as a void pointer parameter (the same buffer contains also the
read/written values). The register address occupies only as many bytes
as it requires at the beginning of this buffer. For example if the
.reg_bits member in regmap_config is 16 (as is the case for this
driver), the register address occupies only the first 2 bytes in this
buffer, so it can be cast to u16.
But the original commit implementing these bulk read/write methods cast
the buffer to u32:
u32 reg = *(u32 *)reg_buf & U16_MAX;
taking the first 4 bytes. This works on little endian systems where the
first 2 bytes of the buffer correspond to the low 16-bits, but it
obviously cannot work on big endian systems.
Fix this by casting the beginning of the buffer to u16 as
u32 reg = *(u16 *)reg_buf;

This series fixes some issues in the Lynx 28G SerDes driver, namely an

The protocol converter configuration registers PCC8, PCCC, PCCD
(implemented by the driver), as well as others, control protocol
converters from multiple lanes (each represented as a different
struct phy). So, if there are simultaneous calls to phy_set_mode_ext()
to lanes sharing the same PCC register (either for the "old" or for the
"new" protocol), corruption of the values programmed to hardware is
possible, because lynx_28g_rmw() has no locking.
Add a spinlock in the struct lynx_28g_priv shared by all lanes, and take
the global spinlock from the phy_ops :: set_mode() implementation. There
are no other callers which modify PCC registers.
