[PATCH v2] net: chelsio: cxgb4: Avoid potential negative array offset
by Kees Cook
Using min_t(int, ...) as a potential array index implies to the compiler
that negative offsets should be allowed. This is not the case, though.
Replace "int" with "unsigned int". Fixes the following warning exposed
under future CONFIG_FORTIFY_SOURCE improvements:

Re: [PATCH 1/7] kthread: Don't allocate kthread_struct for init and umh
by Eric W. Biederman
chill <maximkabox13(a)gmail.com> writes:
> this looks like a real uaf vulnerability and can be executed by the user
The potential to use memory after it has been freed appears completely
real. As such it is a bug and it should definitely be fixed. That is
as far as I can see.
What I don't see, and I am very bad at this so I could be missing
something, is what bad thing kthread_is_per_cpu could be tricked into
doing.
I see a window of a single instruction which reads a single bit
that normally will return false. If that bit instead reads true
it looks like the scheduler will simply decide to not run the
process on another cpu.
So I will put this change in linux-next. It will be tested and I will
send it to Linus when the merge window for v5.19 opens. After Linus
merges this I expect after a week or so it will be backported to the
various stable kernels. Not that it needs to go farther than about
v5.17 where I introduced the bug.

Bspec has added some steps that check forDMC MMIO range before
programming them
v2: Fix for CI
v3: move register defines to .h (Anusha)
- Check MMIO restrictions per pipe
- Add MMIO restricton for v1 dmc header as well (Lucas)
v4: s/_PICK/_PICK_EVEN and use it only for Pipe DMC scenario.
- clean up sanity check logic.(Lucas)
- Add MMIO range for RKL as well.(Anusha)
v5: Use DISPLAY_VER instead of per platform check (Lucas)

[PATCH v2] gpio: pca953x: fix irq_stat not updated when irq is disabled (irq_mask not set)
by Puyou Lu
When one port's input state get inverted (eg. from low to hight) after
pca953x_irq_setup but before setting irq_mask (by some other driver such as
"gpio-keys"), the next inversion of this port (eg. from hight to low) will not
be triggered any more (because irq_stat is not updated at the first time). Issue
should be fixed after this commit.

[PATCH 06/19] iommu/vt-d: Fix clearing real DMA device's scalable-mode context entries
by Kun(llfl)
From: Lu Baolu <baolu.lu(a)linux.intel.com>
ANBZ: #1105
commit 474dd1c6506411752a9b2f2233eec11f1733a099 upstream.
The commit 2b0140c69637e ("iommu/vt-d: Use pci_real_dma_dev() for mapping")
fixes an issue of "sub-device is removed where the context entry is cleared
for all aliases". But this commit didn't consider the PASID entry and PASID
table in VT-d scalable mode. This fix increases the coverage of scalable
mode.

[PATCH 05/19] iommu/vt-d: Global devTLB flush when present context entry changed
by Kun(llfl)
From: Sanjay Kumar <sanjay.k.kumar(a)intel.com>
ANBZ: #1105
commit 37764b952e1b39053defc7ebe5dcd8c4e3e78de9 upstream.
This fixes a bug in context cache clear operation. The code was not
following the correct invalidation flow. A global device TLB invalidation
should be added after the IOTLB invalidation. At the same time, it
uses the domain ID from the context entry. But in scalable mode, the
domain ID is in PASID table entry, not context entry.

[PATCH 2/3] Revert "drm/i915: Propagate errors on awaiting already signaled fences"
by Alan Previn
From: Jason Ekstrand <jason(a)jlekstrand.net>
This reverts commit 9e31c1fe45d555a948ff66f1f0e3fe1f83ca63f7. Ever
since that commit, we've been having issues where a hang in one client
can propagate to another. In particular, a hang in an app can propagate
to the X server which causes the whole desktop to lock up.
Error propagation along fences sound like a good idea, but as your bug
shows, surprising consequences, since propagating errors across security
boundaries is not a good thing.
What we do have is track the hangs on the ctx, and report information to
userspace using RESET_STATS. That's how arb_robustness works. Also, if my
understanding is still correct, the EIO from execbuf is when your context
is banned (because not recoverable or too many hangs). And in all these
cases it's up to userspace to figure out what is all impacted and should
be reported to the application, that's not on the kernel to guess and
automatically propagate.
What's more, we're also building more features on top of ctx error
reporting with RESET_STATS ioctl: Encrypted buffers use the same, and the
userspace fence wait also relies on that mechanism. So it is the path
going forward for reporting gpu hangs and resets to userspace.
So all together that's why I think we should just bury this idea again as
not quite the direction we want to go to, hence why I think the revert is
the right option here.
For backporters: Please note that you _must_ have a backport of
https://lore.kernel.org/dri-devel/20210602164149.391653-2-jason@jlekstrand.…
for otherwise backporting just this patch opens up a security bug.

accidentally lost.

[PATCH 1/3] drm/i915: Revert "drm/i915/gem: Asynchronous cmdparser"
by Alan Previn
From: Jason Ekstrand <jason(a)jlekstrand.net>
This reverts 686c7c35abc2 ("drm/i915/gem: Asynchronous cmdparser"). The
justification for this commit in the git history was a vague comment
about getting it out from under the struct_mutex. While this may
improve perf for some workloads on Gen7 platforms where we rely on the
command parser for features such as indirect rendering, no numbers were
provided to prove such an improvement. It claims to closed two
gitlab/bugzilla issues but with no explanation whatsoever as to why or
what bug it's fixing.
Meanwhile, by moving command parsing off to an async callback, it leaves
us with a problem of what to do on error. When things were synchronous,
EXECBUFFER2 would fail with an error code if parsing failed. When
moving it to async, we needed another way to handle that error and the
solution employed was to set an error on the dma_fence and then trust
that said error gets propagated to the client eventually. Moving back
to synchronous will help us untangle the fence error propagation mess.
This also reverts most of 0edbb9ba1bfe ("drm/i915: Move cmd parser
pinning to execbuffer") which is a refactor of some of our allocation
paths for asynchronous parsing. Now that everything is synchronous, we
don't need it.

[PATCH v2 07/11] crypto: qat - set to zero DH parameters before free
by Giovanni Cabiddu
Set to zero the DH context buffers containing the DH key before they are
freed.
This is to make sure keys are not leaked out by a subsequent memory
allocation.

[PATCH v2 08/11] crypto: qat - add param check for RSA
by Giovanni Cabiddu
Reject requests with a source buffer that is bigger than the size of the
key. This is to prevent a possible integer underflow that might happen
when copying the source scatterlist into a linear buffer.

[PATCH v2 06/11] crypto: qat - remove dma_free_coherent() for DH
by Giovanni Cabiddu
The functions qat_dh_compute_value() allocates memory with
dma_alloc_coherent() if the source or the destination buffers are made
of multiple flat buffers or of a size that is not compatible with the
hardware.
This memory is then freed with dma_free_coherent() in the context of a
tasklet invoked to handle the response for the corresponding request.
According to Documentation/core-api/dma-api-howto.rst, the function
dma_free_coherent() cannot be called in an interrupt context.
Replace allocations with dma_alloc_coherent() in the function
qat_dh_compute_value() with kmalloc() + dma_map_single().

[PATCH v2 05/11] crypto: qat - remove dma_free_coherent() for RSA
by Giovanni Cabiddu
After commit f5ff79fddf0e ("dma-mapping: remove CONFIG_DMA_REMAP"), if
the algorithms are enabled, the driver crashes with a BUG_ON while
executing vunmap() in the context of a tasklet. This is due to the fact
that the function dma_free_coherent() cannot be called in an interrupt
context (see Documentation/core-api/dma-api-howto.rst).
The functions qat_rsa_enc() and qat_rsa_dec() allocate memory with
dma_alloc_coherent() if the source or the destination buffers are made
of multiple flat buffers or of a size that is not compatible with the
hardware.
This memory is then freed with dma_free_coherent() in the context of a
tasklet invoked to handle the response for the corresponding request.
Replace allocations with dma_alloc_coherent() in the functions
qat_rsa_enc() and qat_rsa_dec() with kmalloc() + dma_map_single().

[PATCH v2 04/11] crypto: qat - fix memory leak in RSA
by Giovanni Cabiddu
When an RSA key represented in form 2 (as defined in PKCS #1 V2.1) is
used, some components of the private key persist even after the TFM is
released.
Replace the explicit calls to free the buffers in qat_rsa_exit_tfm()
with a call to qat_rsa_clear_ctx() which frees all buffers referenced in
the TFM context.

[PATCH v2 03/11] crypto: qat - add backlog mechanism
by Giovanni Cabiddu
The implementations of the crypto algorithms (aead, skcipher, etc) in
the QAT driver do not properly support requests with the
CRYPTO_TFM_REQ_MAY_BACKLOG flag set. If the HW queue is full, the driver
returns -EBUSY but does not enqueue the request. This can result in
applications like dm-crypt waiting indefinitely for the completion of a
request that was never submitted to the hardware.
Fix this by adding a software backlog queue: if the ring buffer is more
than eighty percent full, then the request is enqueued to a backlog
list and the error code -EBUSY is returned back to the caller.
Requests in the backlog queue are resubmitted at a later time, in the
context of the callback of a previously submitted request.
The request for which -EBUSY is returned is then marked as -EINPROGRESS
once submitted to the HW queues.
The submission loop inside the function qat_alg_send_message() has been
modified to decide which submission policy to use based on the request
flags. If the request does not have the CRYPTO_TFM_REQ_MAY_BACKLOG set,
the previous behaviour has been preserved.

[PATCH v2 02/11] crypto: qat - refactor submission logic
by Giovanni Cabiddu
All the algorithms in qat_algs.c and qat_asym_algs.c use the same
pattern to submit messages to the HW queues. Move the submission loop
to a new function, qat_alg_send_message(), and share it between the
symmetric and the asymmetric algorithms.
As part of this rework, since the number of retries before returning an
error is inconsistent between the symmetric and asymmetric
implementations, set it to a value that works for both (i.e. 20, was 10
in qat_algs.c and 100 in qat_asym_algs.c)
In addition fix the return code reported when the HW queues are full.
In that case return -ENOSPC instead of -EBUSY.
Including stable in CC since (1) the error code returned if the HW queues
are full is incorrect and (2) to facilitate the backport of the next fix
"crypto: qat - add backlog mechanism".

[PATCH v2 01/11] crypto: qat - use pre-allocated buffers in datapath
by Giovanni Cabiddu
In order to do DMAs, the QAT device requires that the scatterlist
structures are mapped and translated into a format that the firmware can
understand. This is defined as the composition of a scatter gather list
(SGL) descriptor header, the struct qat_alg_buf_list, plus a variable
number of flat buffer descriptors, the struct qat_alg_buf.
The allocation and mapping of these data structures is done each time a
request is received from the skcipher and aead APIs.
In an OOM situation, this behaviour might lead to a dead-lock if an
allocation fails.
Based on the conversation in [1], increase the size of the aead and
skcipher request contexts to include an SGL descriptor that can handle
a maximum of 4 flat buffers.
If requests exceed 4 entries buffers, memory is allocated dynamically.

Register ARMADA_370_XP_INT_FABRIC_MASK_OFFS is Armada 370 and XP specific
and on new Armada platforms it has different meaning. It does not configure
Performance Counter Overflow interrupt masking. So do not touch this
register on non-A370/XP platforms (A375, A38x and A39x).

I Need Your Assistance
by Mr.Roman
My Good Friend,
Before I introduce myself, I wish to inform you that this mail is not
a hoax mail and I urge you to treat it seriously. This mail must come
to you as a big surprise, but I believe it is only a day that people
meet and become great friends and business partners. Please I want you
to read this mail very carefully and I must apologize for barging this
message into your mail box without any formal introduction due to the
urgency and confidentiality of this business and I know that this
message willcome to you as a surprise. Please this is not a joke and I
will notlike you to joke with it ok, with due respect to your person
and much
sincerity of purpose, I make this contact with you as I believe that
you can be of great assistance to me. My name is Mr. Roman Arkadyevich
Abramovich (born 24 October 1966)I am a billionaire Russian oligarch
and politician. I hold joint Israeli and Portuguese citizenships.
Please see this as a confidential message and do not reveal it to
another person and let me know whether you can be of assistance
regarding my proposal below because it is top secret.
I am one of seven oligarchs sanctioned by the UK government over the
2022 Russian invasion of Ukraine which i never supported, including
asset freezes and travel bans. But now as all my acounts and valuable
assets have been frozen and conphisicated. There is this very account
i opened without my identity and now i cannot claim it with my name
and identity because it was opened in an escrow account in a bank in
Africa when i was scouting for good african players to play for my
club Chelsea,the funds in the bank is (£250,000,000 million British
Pounds)two hundred and fiffty million British pounds.This is where you
come in now as the beneficiary of the said fund because i left the
space of the beneficiary open for me to claim the funds back through a
trusted beneficiary like you.
Please if you can stand and transfer this fund to your designated
account as the beneficiary i will back you up with the neccessary
information that you will need. I want you to know that this is a
hundrd percent risk free transaction if you follow my instructions
there will be no mistakes.Once the fund is transferred into your
account please take only (£50,000,000 million Pounds) and keep the
rest (£200,000,000 million Pounds) for me. i will inform you in my
next mail on how to invest the money in your own country.
If you are willing to assist me on this i will feed you with more details.
sincerely,
Mr.R.Abramovich.

[PATCH 02/12] crypto: qat - refactor submission logic
by Giovanni Cabiddu
Move the submission loop to a new function, qat_alg_send_message(), and
share it between the symmetric and the asymmetric algorithms.
If the HW queues are full return -ENOSPC instead of -EBUSY.
For both symmetric and asymmetric services set the number of retries
before returning an error to a value that works for both, 20 (was 10 for
symmetric and 100 for asymmetric).

[PATCH 12/12] crypto: qat - re-enable registration of algorithms
by Giovanni Cabiddu
Re-enable the registration of algorithms after fixes to (1) use
pre-allocated buffers in the datapath and (2) support the
CRYPTO_TFM_REQ_MAY_BACKLOG flag.
This reverts commit 8893d27ffcaf6ec6267038a177cb87bcde4dd3de.

[PATCH 06/12] crypto: qat - remove dma_free_coherent() for DH
by Giovanni Cabiddu
The functions qat_dh_compute_value() allocates memory with
dma_alloc_coherent() if the source or the destination buffers are made
of multiple flat buffers or of a size that is not compatible with the
hardware.
This memory is then freed with dma_free_coherent() in the context of a
tasklet invoked to handle the response for the corresponding request.
According to Documentation/core-api/dma-api-howto.rst, the function
dma_free_coherent() cannot be called in an interrupt context.
Replace allocations with dma_alloc_coherent() in the function
qat_dh_compute_value() with kmalloc() + dma_map_single().

[PATCH 05/12] crypto: qat - remove dma_free_coherent() for RSA
by Giovanni Cabiddu
After commit f5ff79fddf0e ("dma-mapping: remove CONFIG_DMA_REMAP"), if
the algorithms are enabled, the driver crashes with a BUG_ON while
executing vunmap() in the context of a tasklet. This is due to the fact
that the function dma_free_coherent() cannot be called in an interrupt
context (see Documentation/core-api/dma-api-howto.rst).
The functions qat_rsa_enc() and qat_rsa_dec() allocate memory with
dma_alloc_coherent() if the source or the destination buffers are made
of multiple flat buffers or of a size that is not compatible with the
hardware.
This memory is then freed with dma_free_coherent() in the context of a
tasklet invoked to handle the response for the corresponding request.
Replace allocations with dma_alloc_coherent() in the functions
qat_rsa_enc() and qat_rsa_dec() with kmalloc() + dma_map_single().

[PATCH 04/12] crypto: qat - fix memory leak in RSA
by Giovanni Cabiddu
When an RSA key represented in form 2 (as defined in PKCS #1 V2.1) is
used, some components of the private key persist even after the TFM is
released.
Replace the explicit calls to free the buffers in qat_rsa_exit_tfm()
with a call to qat_rsa_clear_ctx() which frees all buffers referenced in
the TFM context.

[PATCH 03/12] crypto: qat - add backlog mechanism
by Giovanni Cabiddu
The implementations of the crypto algorithms (aead, skcipher, etc) in
the QAT driver do not properly support requests with the
CRYPTO_TFM_REQ_MAY_BACKLOG flag set. If the HW queue is full, the driver
returns -EBUSY but does not enqueue the request. This can result in
applications like dm-crypt waiting indefinitely for the completion of a
request that was never submitted to the hardware.
Fix this by adding a software backlog queue: if the ring buffer is more
than eighty percent full, then the request is enqueued to a backlog
list and the error code -EBUSY is returned back to the caller.
Requests in the backlog queue are resubmitted at a later time, in the
context of the callback of a previously submitted request.
The request for which -EBUSY is returned is then marked as -EINPROGRESS
once submitted to the HW queues.
The submission loop inside the function qat_alg_send_message() has been
modified to decide which submission policy to use based on the request
flags. If the request does not have the CRYPTO_TFM_REQ_MAY_BACKLOG set,
the previous behaviour has been preserved.

[PATCH 01/12] crypto: qat - use pre-allocated buffers in datapath
by Giovanni Cabiddu
In order to do DMAs, the QAT device requires that the scatterlist
structures are mapped and translated into a format that the firmware can
understand. This is defined as the composition of a scatter gather list
(SGL) descriptor header, the struct qat_alg_buf_list, plus a variable
number of flat buffer descriptors, the struct qat_alg_buf.
The allocation and mapping of these data structures is done each time a
request is received from the skcipher and aead APIs.
In an OOM situation, this behaviour might lead to a dead-lock if an
allocation fails.
Based on the conversation in [1], increase the size of the aead and
skcipher request contexts to include an SGL descriptor that can handle
a maximum of 4 flat buffers.
If requests exceed 4 entries buffers, memory is allocated dynamically.

patch "firmware_loader: use kernel credentials when reading firmware" added to driver-core-linus
by gregkh＠linuxfoundation.org
This is a note to let you know that I've just added the patch titled
firmware_loader: use kernel credentials when reading firmware
to my driver-core git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git
in the driver-core-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: firmware_loader: use kernel credentials when reading firmware
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Device drivers may decide to not load firmware when probed to avoid
slowing down the boot process should the firmware filesystem not be
available yet. In this case, the firmware loading request may be done
when a device file associated with the driver is first accessed. The
credentials of the userspace process accessing the device file may be
used to validate access to the firmware files requested by the driver.
Ensure that the kernel assumes the responsibility of reading the
firmware.
This was observed on Android for a graphic driver loading their firmware
when the device file (e.g. /dev/mali0) was first opened by userspace
(i.e. surfaceflinger). The security context of surfaceflinger was used
to validate the access to the firmware file (e.g.
/vendor/firmware/mali.bin).
Previously, Android configurations were not setting up the
firmware_class.path command line argument and were relying on the
userspace fallback mechanism. In this case, the security context of the
userspace daemon (i.e. ueventd) was consistently used to read firmware
files. More Android devices are now found to set firmware_class.path
which gives the kernel the opportunity to read the firmware directly
(via kernel_read_file_from_path_initns). In this scenario, the current
process credentials were used, even if unrelated to the loading of the
firmware file.

[PATCH stable] can: isotp: remove re-binding of bound socket
by Oliver Hartkopp
[ Upstream commit 72ed3ee9fa0b461ad086403a8b5336154bd82234 ]
As a carry over from the CAN_RAW socket (which allows to change the CAN
interface while mantaining the filter setup) the re-binding of the
CAN_ISOTP socket needs to take care about CAN ID address information and
subscriptions. It turned out that this feature is so limited (e.g. the
sockopts remain fix) that it finally has never been needed/used.
In opposite to the stateless CAN_RAW socket the switching of the CAN ID
subscriptions might additionally lead to an interrupted ongoing PDU
reception. So better remove this unneeded complexity.
Fixes: e057dd3fc20f ("can: add ISO 15765-2:2016 transport protocol")

[PATCH v3] f2fs: fix to do sanity check on total_data_blocks
by Chao Yu

The root cause is: ckpt.valid_block_count is inconsistent with SIT table,
stat info indicates filesystem has free blocks, but SIT table indicates
filesystem has no free segment.
So that during garbage colloection, it triggers panic when LFS allocator
fails to find free segment.
This patch tries to fix this issue by checking consistency in between
ckpt.valid_block_count and block accounted from SIT.

[PATCH net v2 1/2] net: phy: micrel: Do not use kszphy_suspend/resume for KSZ8061
by Fabio Estevam
From: Fabio Estevam <festevam(a)denx.de>
Since commit f1131b9c23fb ("net: phy: micrel: use
kszphy_suspend()/kszphy_resume for irq aware devices") the following
NULL pointer dereference is observed on a board with KSZ8061:
# udhcpc -i eth0
udhcpc: started, v1.35.0
8<--- cut here ---
Unable to handle kernel NULL pointer dereference at virtual address 00000008
pgd = f73cef4e
[00000008] *pgd=00000000
Internal error: Oops: 5 [#1] SMP ARM
Modules linked in:
CPU: 0 PID: 196 Comm: ifconfig Not tainted 5.15.37-dirty #94
Hardware name: Freescale i.MX6 SoloX (Device Tree)
PC is at kszphy_config_reset+0x10/0x114
LR is at kszphy_resume+0x24/0x64
...
The KSZ8061 phy_driver structure does not have the .probe/..driver_data
fields, which means that priv is not allocated.
This causes the NULL pointer dereference inside kszphy_config_reset().
Fix the problem by using the generic suspend/resume functions as before.
Another alternative would be to provide the .probe and .driver_data
information into the structure, but to be on the safe side, let's
just restore Ethernet functionality by using the generic suspend/resume.

The root cause is: ckpt.valid_block_count is inconsistent with SIT table,
stat info indicates filesystem has free blocks, but SIT table indicates
filesystem has no free segment.
So that during garbage colloection, it triggers panic when LFS allocator
fails to find free segment.
This patch tries to fix this issue by checking consistency in between
ckpt.valid_block_count and block accounted from SIT.

[PATCH] net: chelsio: cxgb4: Avoid potential negative array offset
by Kees Cook
Using min_t(int, ...) as a potential array index implies to the compiler
that negative offsets should be allowed. This is not the case, though.
Replace min_t() with clamp_t(). Fixes the following warning exposed
under future CONFIG_FORTIFY_SOURCE improvements:

With the FEC driver phydev->adjust_link() calls fec_enet_adjust_link()
calls fec_stop()/fec_restart() and both these function reset and
temporary disable the FEC disrupting any MII transaction that
could be happening at the same time.
fec_enet_adjust_link() and phy_read() can be running at the same time
when we have one additional interrupt before the phy_state_machine() is
able to terminate.
Thread 1 (phylib WQ) | Thread 2 (phy interrupt)
|
| phy_interrupt() <-- PHY IRQ
| handle_interrupt()
| phy_read()
| phy_trigger_machine()
| --> schedule phylib WQ

phy_check_link_status() |
phy_link_change() |
phydev->adjust_link() |
fec_enet_adjust_link() |
--> FEC reset | phy_interrupt() <-- PHY IRQ
| phy_read()
|
Fix this by acquiring the phydev lock in phy_interrupt().

fsl_lpuart: Don't enable interrupts too early
to my tty git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-linus branch.
The patch will show up in the next release of the linux-next tree

Subject: fsl_lpuart: Don't enable interrupts too early
If an irq is pending when devm_request_irq() is called, the irq
handler will cause a NULL pointer access because initialisation
is not done yet.

Set the FEATURE_SEL at probe time to make sure that BIT(0) is enabled:
this guarantees that when the port is configured as AP UART, the

Subject: serial: 8250_mtk: Fix UART_EFR register address
On MediaTek SoCs, the UART IP is 16550A compatible, but there are some
specific quirks: we are declaring a register shift of 2, but this is
only valid for the majority of the registers, as there are some that
are out of the standard layout.
Specifically, this driver is using definitions from serial_reg.h, where
we have a UART_EFR register defined as 2: this results in a 0x8 offset,
but there we have the FCR register instead.
The right offset for the EFR register on MediaTek UART is at 0x98,
so, following the decimal definition convention in serial_reg.h and
accounting for the register left shift of two, add and use the correct
register address for this IP, defined as decimal 38, so that the final
calculation results in (0x26 << 2) = 0x98.

patch "tty/serial: digicolor: fix possible null-ptr-deref in" added to tty-linus
by gregkh＠linuxfoundation.org
This is a note to let you know that I've just added the patch titled
tty/serial: digicolor: fix possible null-ptr-deref in
to my tty git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: tty/serial: digicolor: fix possible null-ptr-deref in
digicolor_uart_probe()
It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.

When x_char is to be sent, the TX path overwrites whatever is in the
circular buffer at offset 0 with x_char and sends it using
pch_uart_hal_write(). I don't understand how this was supposed to work
if xmit->buf[0] already contained some character. It must have been
lost.
Remove this whole pop_tx_x() concept and do the work directly in the
callers. (Without printing anything using dev_dbg().)

Subject: usb: gadget: uvc: allow for application to cleanly shutdown
Several types of kernel panics can occur due to timing during the uvc
gadget removal. This appears to be a problem with gadget resources being
managed by both the client application's v4l2 open/close and the UDC
gadget bind/unbind. Since the concept of USB_GADGET_DELAYED_STATUS
doesn't exist for unbind, add a wait to allow for the application to
close out.
Some examples of the panics that can occur are:

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Returning an error value in an i2c remove callback results in an error
message being emitted by the i2c core, but otherwise it doesn't make a
difference. The device goes away anyhow and the devm cleanups are
called.
In this case the remove callback even returns early without stopping the
tcpm worker thread and various timers. A work scheduled on the work
queue, or a firing timer after tcpci_remove() returned probably results
in a use-after-free situation because the regmap and driver data were
freed. So better make sure that tcpci_unregister_port() is called even
if disabling the irq failed.
Also emit a more specific error message instead of the i2c core's
"remove failed (EIO), will be ignored" and return 0 to suppress the
core's warning.
This patch is (also) a preparation for making i2c remove callbacks
return void.

Subject: usb: cdc-wdm: fix reading stuck on device close
cdc-wdm tracks whether a response reading request is in-progress and
blocks the next request from being sent until the previous request is
completed. As soon as last user closes the cdc-wdm device file, the
driver cancels any ongoing requests, resets the pending response
counter, but leaves the response reading in-progress flag
(WDM_RESPONDING) untouched.
So if the user closes the device file during the response receive
request is being performed, no more data will be obtained from the
modem. The request will be cancelled, effectively preventing the
WDM_RESPONDING flag from being reseted. Keeping the flag set will
prevent a new response receive request from being sent, permanently
blocking the read path. The read path will staying blocked until the
module will be reloaded or till the modem will be re-attached.
This stuck has been observed with a Huawei E3372 modem attached to an
OpenWrt router and using the comgt utility to set up a network
connection.
Fix this issue by clearing the WDM_RESPONDING flag on the device file
close.
Without this fix, the device reading stuck can be easily reproduced in a
few connection establishing attempts. With this fix, a load test for
modem connection re-establishing worked for several hours without any
issues.

[PATCH v3] cgroup/cpuset: Remove cpus_allowed/mems_allowed setup in cpuset_init_smp()

2) start_kernel -> cgroup_init() -> cpuset_bind()
3) kernel_init_freeable() -> do_basic_setup() -> cpuset_init_smp()
The first cpuset_init() call just sets all the bits in the masks.
The second cpuset_bind() call sets cpus_allowed and mems_allowed to the
default v2 values. The third cpuset_init_smp() call sets them back to
v1 values.
For systems with cgroup v2 setup, cpuset_bind() is called once. As a
result, cpu and memory node hot add may fail to update the cpu and node
masks of the top cpuset to include the newly added cpu or node in a
cgroup v2 environment.
For systems with cgroup v1 setup, cpuset_bind() is called again by
rebind_subsystem() when the v1 cpuset filesystem is mounted as shown
in the dmesg log below with an instrumented kernel.
[ 2.609781] cpuset_bind() called - v2 = 1
[ 3.079473] cpuset_init_smp() called
[ 7.103710] cpuset_bind() called - v2 = 0
smp_init() is called after the first two init functions. So we don't
have a complete list of active cpus and memory nodes until later in
cpuset_init_smp() which is the right time to set up effective_cpus
and effective_mems.
To fix this cgroup v2 mask setup problem, the potentially incorrect
cpus_allowed & mems_allowed setting in cpuset_init_smp() are removed.
For cgroup v2 systems, the initial cpuset_bind() call will set the masks
correctly. For cgroup v1 systems, the second call to cpuset_bind()
will do the right setup.

[PATCH v4 07/12] ptrace: Reimplement PTRACE_KILL by always sending SIGKILL
by Eric W. Biederman
The current implementation of PTRACE_KILL is buggy and has been for
many years as it assumes it's target has stopped in ptrace_stop. At a
quick skim it looks like this assumption has existed since ptrace
support was added in linux v1.0.
While PTRACE_KILL has been deprecated we can not remove it as
a quick search with google code search reveals many existing
programs calling it.
When the ptracee is not stopped at ptrace_stop some fields would be
set that are ignored except in ptrace_stop. Making the userspace
visible behavior of PTRACE_KILL a noop in those case.
As the usual rules are not obeyed it is not clear what the
consequences are of calling PTRACE_KILL on a running process.
Presumably userspace does not do this as it achieves nothing.
Replace the implementation of PTRACE_KILL with a simple
send_sig_info(SIGKILL) followed by a return 0. This changes the
observable user space behavior only in that PTRACE_KILL on a process
not stopped in ptrace_stop will also kill it. As that has always
been the intent of the code this seems like a reasonable change.

[PATCH v4 04/12] ptrace/xtensa: Replace PT_SINGLESTEP with TIF_SINGLESTEP
by Eric W. Biederman
xtensa is the last user of the PT_SINGLESTEP flag. Changing tsk->ptrace in
user_enable_single_step and user_disable_single_step without locking could
potentiallly cause problems.
So use a thread info flag instead of a flag in tsk->ptrace. Use TIF_SINGLESTEP
that xtensa already had defined but unused.
Remove the definitions of PT_SINGLESTEP and PT_BLOCKSTEP as they have no more users.

[PATCH v4 03/12] ptrace/um: Replace PT_DTRACE with TIF_SINGLESTEP
by Eric W. Biederman
User mode linux is the last user of the PT_DTRACE flag. Using the flag to indicate
single stepping is a little confusing and worse changing tsk->ptrace without locking
could potentionally cause problems.
So use a thread info flag with a better name instead of flag in tsk->ptrace.
Remove the definition PT_DTRACE as uml is the last user.

Subject: [PATCH] mm: fix unexpected zeroed page mapping with zram swap
Two processes under CLONE_VM cloning, user process can be corrupted by
seeing zeroed page unexpectedly.
CPU A CPU B
do_swap_page do_swap_page
SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path
swap_readpage valid data
swap_slot_free_notify
delete zram entry
swap_readpage zeroed(invalid) data
pte_lock
map the *zero data* to userspace
pte_unlock
pte_lock
if (!pte_same)
goto out_nomap;
pte_unlock
return and next refault will
read zeroed data
The swap_slot_free_notify is bogus for CLONE_VM case since it doesn't
increase the refcount of swap slot at copy_mm so it couldn't catch up
whether it's safe or not to discard data from backing device. In the
case, only the lock it could rely on to synchronize swap slot freeing is
page table lock. Thus, this patch gets rid of the swap_slot_free_notify
function. With this patch, CPU A will see correct data.
CPU A CPU B
do_swap_page do_swap_page
SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path
swap_readpage original data
pte_lock
map the original data
swap_free
swap_range_free
bd_disk->fops->swap_slot_free_notify
swap_readpage read zeroed data
pte_unlock
pte_lock
if (!pte_same)
goto out_nomap;
pte_unlock
return
on next refault will see mapped data by CPU B
The concern of the patch would increase memory consumption since it
could keep wasted memory with compressed form in zram as well as
uncompressed form in address space. However, most of cases of zram uses
no readahead and do_swap_page is followed by swap_free so it will free
the compressed form from in zram quickly.

[PATCH v2] arm64: paravirt: Use RCU read locks to guard stolen_time
by Elliot Berman
From: Prakruthi Deepak Heragu <quic_pheragu(a)quicinc.com>
During hotplug, the stolen time data structure is unmapped and memset.
There is a possibility of the timer IRQ being triggered before memset
and stolen time is getting updated as part of this timer IRQ handler. This
causes the below crash in timer handler -

Re: Crash on resume after suspend (5.17.5 and 5.15.36)

That’s a pity, but okay, of course. Thanks for reporting this bug.
Since you are using Arch and the Wiki is quite detailed, you could try
setting up a swap on an unused USB stick floating around. This should be
the easiest setup. Make sure to add resume to the mkinitcpio hooks after
udev, but before fsck and add the resume parameter to your bootloader as
described in the Wiki. This should get you going.
Don’t make this a permanent setup, if you use encryption or like
performance. The permanent solution would be creating a swap partition
or, if that is not feasible, a swap file while considering the Wiki
notes for e.g. btrfs.
Best regards,
Manuel

[tip: irq/urgent] genirq: Synchronize interrupt thread startup

genirq: Synchronize interrupt thread startup
A kernel hang can be observed when running setserial in a loop on a kernel
with force threaded interrupts. The sequence of events is:
setserial
open("/dev/ttyXXX")
request_irq()
do_stuff()
-> serial interrupt
-> wake(irq_thread)
desc->threads_active++;
close()
free_irq()
kthread_stop(irq_thread)
synchronize_irq() <- hangs because desc->threads_active != 0
The thread is created in request_irq() and woken up, but does not get on a
CPU to reach the actual thread function, which would handle the pending
wake-up. kthread_stop() sets the should stop condition which makes the
thread immediately exit, which in turn leaves the stale threads_active
count around.
This problem was introduced with commit 519cc8652b3a, which addressed a
interrupt sharing issue in the PCIe code.
Before that commit free_irq() invoked synchronize_irq(), which waits for
the hard interrupt handler and also for associated threads to complete.
To address the PCIe issue synchronize_irq() was replaced with
__synchronize_hardirq(), which only waits for the hard interrupt handler to
complete, but not for threaded handlers.
This was done under the assumption, that the interrupt thread already
reached the thread function and waits for a wake-up, which is guaranteed to
be handled before acting on the stop condition. The problematic case, that
the thread would not reach the thread function, was obviously overlooked.
Make sure that the interrupt thread is really started and reaches
thread_fn() before returning from __setup_irq().
This utilizes the existing wait queue in the interrupt descriptor. The
wait queue is unused for non-shared interrupts. For shared interrupts the
usage might cause a spurious wake-up of a waiter in synchronize_irq() or the
completion of a threaded handler might cause a spurious wake-up of the
waiter for the ready flag. Both are harmless and have no functional impact.

Crash on resume after suspend (5.17.5 and 5.15.36)
by Jordan Leppert
Hi,
A changed was added to both version 5.17.5 and 5.15.36 which causes my computer to freeze when resuming after a suspend. This happens every time I suspend and then resume.
I've bisected the change to commit: cbe6c3a8f8f4315b96e46e1a1c70393c06d95a4c (net: atlantic: invert deep par in pm functions, preventing null derefs)
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=…
My computer details that might be relevant:
OS: Arch Linux
CPU: AMD 5950X
GPU: AMD 6800XT
As expected I have an Aquantia ethernet controller listed in lspci:
05:00.0 Ethernet controller: Aquantia Corp. AQC107 NBase-T/IEEE 802.3bz Ethernet Controller [AQtion] (rev 02)
Please let me know if there is any more info I can give that will help.
Regards,
Jordan

[PATCH 1/2] Revert "drm/i915: Propagate errors on awaiting already signaled fences"
by Alan Previn
From: Jason Ekstrand <jason(a)jlekstrand.net>
This reverts commit 9e31c1fe45d555a948ff66f1f0e3fe1f83ca63f7. Ever
since that commit, we've been having issues where a hang in one client
can propagate to another. In particular, a hang in an app can propagate
to the X server which causes the whole desktop to lock up.
Error propagation along fences sound like a good idea, but as your bug
shows, surprising consequences, since propagating errors across security
boundaries is not a good thing.
What we do have is track the hangs on the ctx, and report information to
userspace using RESET_STATS. That's how arb_robustness works. Also, if my
understanding is still correct, the EIO from execbuf is when your context
is banned (because not recoverable or too many hangs). And in all these
cases it's up to userspace to figure out what is all impacted and should
be reported to the application, that's not on the kernel to guess and
automatically propagate.
What's more, we're also building more features on top of ctx error
reporting with RESET_STATS ioctl: Encrypted buffers use the same, and the
userspace fence wait also relies on that mechanism. So it is the path
going forward for reporting gpu hangs and resets to userspace.
So all together that's why I think we should just bury this idea again as
not quite the direction we want to go to, hence why I think the revert is
the right option here.
For backporters: Please note that you _must_ have a backport of
https://lore.kernel.org/dri-devel/20210602164149.391653-2-jason@jlekstrand.…
for otherwise backporting just this patch opens up a security bug.
v2: Augment commit message. Also restore Jason's sob that I
accidentally lost.
v3: Add a note for backporters

[PATCH net v3 1/2] ping: fix address binding wrt vrf
by Nicolas Dichtel
When ping_group_range is updated, 'ping' uses the DGRAM ICMP socket,
instead of an IP raw socket. In this case, 'ping' is unable to bind its
socket to a local address owned by a vrflite.
Before the patch:
$ sysctl -w net.ipv4.ping_group_range='0 2147483647'
$ ip link add blue type vrf table 10
$ ip link add foo type dummy
$ ip link set foo master blue
$ ip link set foo up
$ ip addr add 192.168.1.1/24 dev foo
$ ip addr add 2001::1/64 dev foo
$ ip vrf exec blue ping -c1 -I 192.168.1.1 192.168.1.2
ping: bind: Cannot assign requested address
$ ip vrf exec blue ping6 -c1 -I 2001::1 2001::2
ping6: bind icmp socket: Cannot assign requested address

[patch 1/3] x86/fpu: Prevent FPU state corruption
by Thomas Gleixner
The FPU usage related to task FPU management is either protected by
disabling interrupts (switch_to, return to user) or via fpregs_lock() which
is a wrapper around local_bh_disable(). When kernel code wants to use the
FPU then it has to check whether it is possible by calling irq_fpu_usable().
But the condition in irq_fpu_usable() is wrong. It allows FPU to be used
when:
!in_interrupt() || interrupted_user_mode() || interrupted_kernel_fpu_idle()
The latter is checking whether some other context already uses FPU in the
kernel, but if that's not the case then it allows FPU to be used
unconditionally even if the calling context interupted a fpregs_lock()
critical region. If that happens then the FPU state of the interrupted
context becomes corrupted.
Allow in kernel FPU usage only when no other context has in kernel FPU
usage and either the calling context is not hard interrupt context or the
hard interrupt did not interrupt a local bottomhalf disabled region.
It's hard to find a proper Fixes tag as the condition was broken in one way
or the other for a very long time and the eager/lazy FPU changes caused a
lot of churn. Picked something remotely connected from the history.
This survived undetected for quite some time as FPU usage in interrupt
context is rare, but the recent changes to the random code unearthed it at
least on a kernel which had FPU debugging enabled. There is probably a
higher rate of silent corruption as not all issues can be detected by the
FPU debugging code. This will be addressed in a subsequent change.
Fixes: 5d2bd7009f30 ("x86, fpu: decouple non-lazy/eager fpu restore from xsave")

[PATCH v3 0/2] mm: fix cma allocation fail sometimes
by Dong Aisheng
We observed an issue with NXP 5.15 LTS kernel that dma_alloc_coherent()
may fail sometimes when there're multiple processes trying to allocate
CMA memory.
This issue can be very easily reproduced on MX6Q SDB board with latest
linux-next kernel by writing a test module creating 16 or 32 threads
allocating random size of CMA memory in parallel at the background.
Or simply enabling CONFIG_CMA_DEBUG, you can see endless of CMA alloc
retries during booting:
[ 1.452124] cma: cma_alloc(): memory range at (ptrval) is busy,retrying
....
(thousands of reties)
The root cause of this issue is that since commit a4efc174b382
("mm/cma.c: remove redundant cma_mutex lock"), CMA supports concurrent
memory allocation.
It's possible that the memory range process A try to alloc has already
been isolated by the allocation of process B during memory migration.
The problem here is that the memory range isolated during one allocation
by start_isolate_page_range() could be much bigger than the real size we
want to alloc due to the range is aligned to MAX_ORDER_NR_PAGES.
Taking an ARMv7 platform with 1G memory as an example, when MAX_ORDER_NR_PAGES
is big (e.g. 32M with max_order 14) and CMA memory is relatively small
(e.g. 128M), there're only 4 MAX_ORDER slot, then it's very easy that
all CMA memory may have already been isolated by other processes when
one trying to allocate memory using dma_alloc_coherent().
Since current CMA code will only scan one time of whole available CMA
memory, then dma_alloc_coherent() may easy fail due to contention with
other processes.
This patchset introduces a retry mechanism to rescan CMA bitmap for -EBUSY
error in case the target pageblock may has been temporarily isolated
by others and released later.
It also improves the CMA allocation performance by trying the next
MAX_ORDER_NR_PAGES range during reties rather than looping within the
same isolated range in small steps which wasting CPU mips.
The following test is based on linux-next: next-20211213.
Without the fix, it's easily fail.

[PATCH v3 07/11] ptrace: Reimplement PTRACE_KILL by always sending SIGKILL
by Eric W. Biederman
The current implementation of PTRACE_KILL is buggy and has been for
many years as it assumes it's target has stopped in ptrace_stop. At a
quick skim it looks like this assumption has existed since ptrace
support was added in linux v1.0.
While PTRACE_KILL has been deprecated we can not remove it as
a quick search with google code search reveals many existing
programs calling it.
When the ptracee is not stopped at ptrace_stop some fields would be
set that are ignored except in ptrace_stop. Making the userspace
visible behavior of PTRACE_KILL a noop in those case.
As the usual rules are not obeyed it is not clear what the
consequences are of calling PTRACE_KILL on a running process.
Presumably userspace does not do this as it achieves nothing.
Replace the implementation of PTRACE_KILL with a simple
send_sig_info(SIGKILL) followed by a return 0. This changes the
observable user space behavior only in that PTRACE_KILL on a process
not stopped in ptrace_stop will also kill it. As that has always
been the intent of the code this seems like a reasonable change.

[PATCH v3 04/11] ptrace/xtensa: Replace PT_SINGLESTEP with TIF_SINGLESTEP
by Eric W. Biederman
xtensa is the last user of the PT_SINGLESTEP flag. Changing tsk->ptrace in
user_enable_single_step and user_disable_single_step without locking could
potentiallly cause problems.
So use a thread info flag instead of a flag in tsk->ptrace. Use TIF_SINGLESTEP
that xtensa already had defined but unused.
Remove the definitions of PT_SINGLESTEP and PT_BLOCKSTEP as they have no more users.

[PATCH v3 03/11] ptrace/um: Replace PT_DTRACE with TIF_SINGLESTEP
by Eric W. Biederman
User mode linux is the last user of the PT_DTRACE flag. Using the flag to indicate
single stepping is a little confusing and worse changing tsk->ptrace without locking
could potentionally cause problems.
So use a thread info flag with a better name instead of flag in tsk->ptrace.
Remove the definition PT_DTRACE as uml is the last user.

This changes fixes a kernel info leak since it's possible for bio_copy_kern to
copy unitialized memory into userspace.
This change had to be manually backported since bio_copy_kern is in a different
