[PATCH 5.4 003/120] gpio: mpc8xxx: Fix support for IRQ_TYPE_LEVEL_LOW flow_type in mpc85xx

[Greg Kroah-Hartman]

From: Pali Rohár <pali@kernel.org>

[ Upstream commit 279c12df8d2efb28def9d037f288cbfb97c30fe2 ]

Commit e39d5ef67804 ("powerpc/5xxx: extend mpc8xxx_gpio driver to support
mpc512x gpios") implemented support for IRQ_TYPE_LEVEL_LOW flow type in
mpc512x via falling edge type. Do same for mpc85xx which support was added
in commit 345e5c8a1cc3 ("powerpc: Add interrupt support to mpc8xxx_gpio").

Fixes probing of lm90 hwmon driver on mpc85xx based board which use level
interrupt. Without it kernel prints error and refuse lm90 to work:

[PATCH 5.4 005/120] drm/meson: Fix OSD1 RGB to YCbCr coefficient

[Greg Kroah-Hartman]

From: Stuart Menefy <stuart.menefy@mathembedded.com>

[ Upstream commit 6463d3930ba5b6addcfc8f80a4543976a2fc7656 ]

VPP_WRAP_OSD1_MATRIX_COEF22.Coeff22 is documented as being bits 0-12,
not 16-28.

Without this the output tends to have a pink hue, changing it results
in better color accuracy.

The vendor kernel doesn't use this register. However the code which
sets VIU2_OSD1_MATRIX_COEF22 also uses bits 0-12. There is a slightly
different style of registers for configuring some of the other matrices,
which do use bits 16-28 for this coefficient, but those have names
ending in MATRIX_COEF22_30, and this is not one of those.

[PATCH 5.4 008/120] efi: libstub: Disable struct randomization

[Greg Kroah-Hartman]

From: Ard Biesheuvel <ardb@kernel.org>

[ Upstream commit 1a3887924a7e6edd331be76da7bf4c1e8eab4b1e ]

The EFI stub is a wrapper around the core kernel that makes it look like
a EFI compatible PE/COFF application to the EFI firmware. EFI
applications run on top of the EFI runtime, which is heavily based on
so-called protocols, which are struct types consisting [mostly] of
function pointer members that are instantiated and recorded in a
protocol database.

These structs look like the ideal randomization candidates to the
randstruct plugin (as they only carry function pointers), but of course,
these protocols are contracts between the firmware that exposes them,
and the EFI applications (including our stubbed kernel) that invoke
them. This means that struct randomization for EFI protocols is not a
great idea, and given that the stub shares very little data with the
core kernel that is represented as a randomizable struct, we're better
off just disabling it completely here.

[PATCH 5.4 009/120] ALSA: pcm: oss: Fix race at SNDCTL_DSP_SYNC

[Greg Kroah-Hartman]

[ Upstream commit 8423f0b6d513b259fdab9c9bf4aaa6188d054c2d ]

There is a small race window at snd_pcm_oss_sync() that is called from
OSS PCM SNDCTL_DSP_SYNC ioctl; namely the function calls
snd_pcm_oss_make_ready() at first, then takes the params_lock mutex
for the rest.  When the stream is set up again by another thread
between them, it leads to inconsistency, and may result in unexpected
results such as NULL dereference of OSS buffer as a fuzzer spotted
recently.

The fix is simply to cover snd_pcm_oss_make_ready() call into the same
params_lock mutex with snd_pcm_oss_make_ready_locked() variant.

[PATCH 5.4 011/120] tracing: hold caller_addr to hardirq_{enable,disable}_ip

[Greg Kroah-Hartman]

From: Yipeng Zou <zouyipeng@huawei.com>

[ Upstream commit 54c3931957f6a6194d5972eccc36d052964b2abe ]

Currently, The arguments passing to lockdep_hardirqs_{on,off} was fixed
in CALLER_ADDR0.
The function trace_hardirqs_on_caller should have been intended to use
caller_addr to represent the address that caller wants to be traced.

For example, lockdep log in riscv showing the last {enabled,disabled} at
__trace_hardirqs_{on,off} all the time(if called by):
[   57.853175] hardirqs last  enabled at (2519): __trace_hardirqs_on+0xc/0x14
[   57.853848] hardirqs last disabled at (2520): __trace_hardirqs_off+0xc/0x14

After use trace_hardirqs_xx_caller, we can get more effective information:
[   53.781428] hardirqs last  enabled at (2595): restore_all+0xe/0x66
[   53.782185] hardirqs last disabled at (2596): ret_from_exception+0xa/0x10

[PATCH 5.4 012/120] cifs: revalidate mapping when doing direct writes

[Greg Kroah-Hartman]

From: Ronnie Sahlberg <lsahlber@redhat.com>

commit 7500a99281dfed2d4a84771c933bcb9e17af279b upstream.

Kernel bugzilla: 216301

When doing direct writes we need to also invalidate the mapping in case
we have a cached copy of the affected page(s) in memory or else
subsequent reads of the data might return the old/stale content
before we wrote an update to the server.

[PATCH 5.4 015/120] iomap: iomap that extends beyond EOF should be marked dirty

[Greg Kroah-Hartman]

From: Chandan Babu R <chandan.babu@oracle.com>

From: Dave Chinner <dchinner@redhat.com>

commit 7684e2c4384d5d1f884b01ab8bff2369e4db0bff upstream.

When doing a direct IO that spans the current EOF, and there are
written blocks beyond EOF that extend beyond the current write, the
only metadata update that needs to be done is a file size extension.

However, we don't mark such iomaps as IOMAP_F_DIRTY to indicate that
there is IO completion metadata updates required, and hence we may
fail to correctly sync file size extensions made in IO completion
when O_DSYNC writes are being used and the hardware supports FUA.

Hence when setting IOMAP_F_DIRTY, we need to also take into account
whether the iomap spans the current EOF. If it does, then we need to
mark it dirty so that IO completion will call generic_write_sync()
to flush the inode size update to stable storage correctly.

[PATCH 5.4 016/120] ASoC: nau8824: Fix semaphore unbalance at error paths

[PATCH 5.4 017/120] regulator: pfuze100: Fix the global-out-of-bounds access in pfuze100_regulator_probe()

[Greg Kroah-Hartman]

From: Xiaolei Wang <xiaolei.wang@windriver.com>

[ Upstream commit 78e1e867f44e6bdc72c0e6a2609a3407642fb30b ]

The pfuze_chip::regulator_descs is an array of size
PFUZE100_MAX_REGULATOR, the pfuze_chip::pfuze_regulators
is the pointer to the real regulators of a specific device.
The number of real regulator is supposed to be less than
the PFUZE100_MAX_REGULATOR, so we should use the size of
'regulator_num * sizeof(struct pfuze_regulator)' in memcpy().
This fixes the out of bounds access bug reported by KASAN.

If the local processor work item for the rxrpc local endpoint gets requeued
by an event (such as an incoming packet) between it getting scheduled for
destruction and the UDP socket being closed, the rxrpc_local_destroyer()
function can get run twice.  The second time it can hang because it can end
up waiting for cleanup events that will never happen.

[PATCH 5.4 021/120] ALSA: hda/tegra: Align BDL entry to 4KB boundary

[Greg Kroah-Hartman]

From: Mohan Kumar <mkumard@nvidia.com>

[ Upstream commit 8d44e6044a0e885acdd01813768a0b27906d64fd ]

AZA HW may send a burst read/write request crossing 4K memory boundary.
The 4KB boundary is not guaranteed by Tegra HDA HW. Make SW change to
include the flag AZX_DCAPS_4K_BDLE_BOUNDARY to align BDLE to 4K
boundary.

[PATCH 5.4 023/120] afs: Return -EAGAIN, not -EREMOTEIO, when a file already locked

[Greg Kroah-Hartman]

From: David Howells <dhowells@redhat.com>

[ Upstream commit 0066f1b0e27556381402db3ff31f85d2a2265858 ]

When trying to get a file lock on an AFS file, the server may return
UAEAGAIN to indicate that the lock is already held.  This is currently
translated by the default path to -EREMOTEIO.

Translate it instead to -EAGAIN so that we know we can retry it.

[PATCH 5.4 025/120] mksysmap: Fix the mismatch of L0 symbols in System.map

[Greg Kroah-Hartman]

From: Youling Tang <tangyouling@loongson.cn>

[ Upstream commit c17a2538704f926ee4d167ba625e09b1040d8439 ]

When System.map was generated, the kernel used mksysmap to filter the
kernel symbols, we need to filter "L0" symbols in LoongArch architecture.

$ cat System.map | grep L0
9000000000221540 t L0

The L0 symbol exists in System.map, but not in .tmp_System.map. When
"cmp -s System.map .tmp_System.map" will show "Inconsistent kallsyms
data" error message in link-vmlinux.sh script.

[PATCH 5.4 029/120] usb: dwc3: gadget: Avoid starting DWC3 gadget during UDC unbind

[Greg Kroah-Hartman]

From: Wesley Cheng <wcheng@codeaurora.org>

[ Upstream commit 8217f07a50236779880f13e87f99224cd9117f83 ]

There is a race present where the DWC3 runtime resume runs in parallel
to the UDC unbind sequence.  This will eventually lead to a possible
scenario where we are enabling the run/stop bit, without a valid
composition defined.

Thread#1 (handling UDC unbind):
usb_gadget_remove_driver()
-->usb_gadget_disconnect()
  -->dwc3_gadget_pullup(0)
--> continue UDC unbind sequence
-->Thread#2 is running in parallel here

Thread#2 (handing next cable connect)
__dwc3_set_mode()
  -->pm_runtime_get_sync()
    -->dwc3_gadget_resume()
      -->dwc->gadget_driver is NOT NULL yet
      -->dwc3_gadget_run_stop(1)
      --> _dwc3gadget_start()
...

Fix this by tracking the pullup disable routine, and avoiding resuming
of the DWC3 gadget.  Once the UDC is re-binded, that will trigger the
pullup enable routine, which would handle enabling the DWC3 gadget.

[PATCH 5.4 030/120] usb: dwc3: Issue core soft reset before enabling run/stop

[Greg Kroah-Hartman]

From: Wesley Cheng <quic_wcheng@quicinc.com>

[ Upstream commit 0066472de157439d58454f4a55786f1045ea5681 ]

It is recommended by the Synopsis databook to issue a DCTL.CSftReset
when reconnecting from a device-initiated disconnect routine.  This
resolves issues with enumeration during fast composition switching
cases, which result in an unknown device on the host.

[PATCH 5.4 031/120] usb: dwc3: gadget: Prevent repeat pullup()

[Greg Kroah-Hartman]

From: Thinh Nguyen <Thinh.Nguyen@synopsys.com>

[ Upstream commit 69e131d1ac4e52a59ec181ab4f8aa8c48cd8fb64 ]

Don't do soft-disconnect if it's previously done. Likewise, don't do
soft-connect if the device is currently connected and running. It would
break normal operation.

Currently the caller of pullup() (udc's sysfs soft_connect) only checks
if it had initiated disconnect to prevent repeating soft-disconnect. It
doesn't check for soft-connect. To be safe, let's keep the check here
regardless whether the udc core is fixed.

[PATCH 5.4 033/120] usb: dwc3: gadget: Dont modify GEVNTCOUNT in pullup()

[Greg Kroah-Hartman]

From: Thinh Nguyen <Thinh.Nguyen@synopsys.com>

[ Upstream commit 8f8034f493b5eb1ad21ff392fd30c0cf9e71f73f ]

If the GEVNTCOUNT indicates events in the event buffer, the driver needs
to acknowledge them before the controller can halt. Simply let the
interrupt handler acknowledges the remaining event generated by the
controller while polling for DSTS.DEVCTLHLT. This avoids disabling irq
and taking care of race condition between the interrupt handlers and
pullup().

[PATCH 5.4 034/120] usb: dwc3: gadget: Avoid duplicate requests to enable Run/Stop

[Greg Kroah-Hartman]

From: Wesley Cheng <quic_wcheng@quicinc.com>

[ Upstream commit 040f2dbd2010c43f33ad27249e6dac48456f4d99 ]

Relocate the pullups_connected check until after it is ensured that there
are no runtime PM transitions.  If another context triggered the DWC3
core's runtime resume, it may have already enabled the Run/Stop.  Do not
re-run the entire pullup sequence again, as it may issue a core soft
reset while Run/Stop is already set.

This patch depends on
  commit 69e131d1ac4e ("usb: dwc3: gadget: Prevent repeat pullup()")

[PATCH 5.4 036/120] usb: xhci-mtk: add only one extra CS for FS/LS INTR

[Greg Kroah-Hartman]

From: Chunfeng Yun <chunfeng.yun@mediatek.com>

[ Upstream commit 1bf661daf6b084bc4d753f55b54f35dc98709685 ]

In USB2 Spec:
"11.18.5 TT Response Generation
In general, there will be two (or more) complete-split
transactions scheduled for a periodic endpoint.
However, for interrupt endpoints, the maximum size of
the full-/low-speed transaction guarantees that it can
never require more than two complete-split transactions.
Two complete-split transactions are only required
when the transaction spans a microframe boundary."

Due to the maxp is 64, and less then 188 (at most in one
microframe), seems never span boundary, so use only one CS
for FS/LS interrupt transfer, this will save some bandwidth.

[PATCH 5.4 041/120] usb: xhci-mtk: relax TT periodic bandwidth allocation

[Greg Kroah-Hartman]

From: Ikjoon Jang <ikjn@chromium.org>

[ Upstream commit 548011957d1d72e0b662300c8b32b81d593b796e ]

Currently xhci-mtk needs software-managed bandwidth allocation for
periodic endpoints, it allocates the microframe index for the first
start-split packet for each endpoint. As this index allocation logic
should avoid the conflicts with other full/low-speed periodic endpoints,
it uses the worst case byte budgets on high-speed bus bandwidth
For example, for an isochronos IN endpoint with 192 bytes budget,
it will consume the whole 4 u-frames(188 * 4) while the actual
full-speed bus budget should be just 192bytes.

This patch changes the low/full-speed bandwidth allocation logic
to use "approximate" best case budget for lower speed bandwidth
management. For the same endpoint from the above example, the
approximate best case budget is now reduced to (188 * 2) bytes.

Without this patch, many usb audio headsets with 3 interfaces
(audio input, audio output, and HID) cannot be configured
on xhci-mtk.

This allows use of the driver with other types of firmware such as ACPI
PRP0001 based probing.

Also part of a general attempt to remove direct use of of_ specific
accessors from IIO.

Added an include for mod_devicetable.h whilst here to cover the
struct of_device_id definition.

[PATCH 5.4 044/120] wifi: mac80211: Fix UAF in ieee80211_scan_rx()

[Greg Kroah-Hartman]

From: Siddh Raman Pant <code@siddh.me>

[ Upstream commit 60deb9f10eec5c6a20252ed36238b55d8b614a2c ]

ieee80211_scan_rx() tries to access scan_req->flags after a
null check, but a UAF is observed when the scan is completed
and __ieee80211_scan_completed() executes, which then calls
cfg80211_scan_done() leading to the freeing of scan_req.

Since scan_req is rcu_dereference()'d, prevent the racing in
__ieee80211_scan_completed() by ensuring that from mac80211's
POV it is no longer accessed from an RCU read critical section
before we call cfg80211_scan_done().

[PATCH 5.4 045/120] tty/serial: atmel: RS485 & ISO7816: wait for TXRDY before sending data

[Greg Kroah-Hartman]

From: Codrin.Ciubotariu@microchip.com <Codrin.Ciubotariu@microchip.com>

[ Upstream commit 477b8383100023ea0769979cff67e9be3a720397 ]

At this moment, TXEMPTY is checked before sending data on RS485 and ISO7816
modes. However, TXEMPTY is risen when FIFO (if used) or the Transmit Shift
Register are empty, even though TXRDY might be up and controller is able to
receive data. Since the controller sends data only when TXEMPTY is ready,
on RS485, when DMA is not used, the RTS pin is driven low after each byte.
With this patch, the characters will be transmitted when TXRDY is up and
so, RTS pin will remain high between bytes.
The performance improvement on RS485 is about 8% with a baudrate of 300.

[PATCH 5.4 046/120] serial: atmel: remove redundant assignment in rs485_config

From: Lino Sanfilippo <LinoSanfilippo@gmx.de>

[ Upstream commit 60efd0513916f195dd85bfbf21653f74f9ab019c ]

In uart_set_rs485_config() the serial core already assigns the passed
serial_rs485 struct to the uart port.

So remove the assignment from the drivers rs485_config() function to avoid
redundancy.

[PATCH 5.4 047/120] tty: serial: atmel: Preserve previous USART mode if RS485 disabled

[Greg Kroah-Hartman]

From: Sergiu Moga <sergiu.moga@microchip.com>

[ Upstream commit 692a8ebcfc24f4a5bea0eb2967e450f584193da6 ]

Whenever the atmel_rs485_config() driver method would be called,
the USART mode is reset to normal mode before even checking if
RS485 flag is set, thus resulting in losing the previous USART
mode in the case where the checking fails.

Some tools, such as `linux-serial-test`, lead to the driver calling
this method when doing the setup of the serial port: after setting the
port mode (Hardware Flow Control, Normal Mode, RS485 Mode, etc.),
`linux-serial-test` tries to enable/disable RS485 depending on
the commandline arguments that were passed.

Example of how this issue could reveal itself:
When doing a serial communication with Hardware Flow Control through
`linux-serial-test`, the tool would lead to the driver roughly doing
the following:
- set the corresponding bit to 1 (ATMEL_US_USMODE_HWHS bit in the
ATMEL_US_MR register) through the atmel_set_termios() to enable
Hardware Flow Control
- disable RS485 through the atmel_config_rs485() method
Thus, when the latter is called, the mode will be reset and the
previously set bit is unset, leaving USART in normal mode instead of
the expected Hardware Flow Control mode.

This fix ensures that this reset is only done if the checking for
RS485 succeeds and that the previous mode is preserved otherwise.

[PATCH 5.4 048/120] usb: add quirks for Lenovo OneLink+ Dock

[Greg Kroah-Hartman]

From: Jean-Francois Le Fillatre <jflf_kernel@gmx.com>

[ Upstream commit 3d5f70949f1b1168fbb17d06eb5c57e984c56c58 ]

The Lenovo OneLink+ Dock contains two VL812 USB3.0 controllers:
17ef:1018 upstream
17ef:1019 downstream

Those two controllers both have problems with some USB3.0 devices,
particularly self-powered ones. Typical error messages include:

  Timeout while waiting for setup device command
  device not accepting address X, error -62
  unable to enumerate USB device

By process of elimination the controllers themselves were identified as
the cause of the problem. Through trial and error the issue was solved
by using USB_QUIRK_RESET_RESUME for both chips.

[PATCH 5.4 050/120] usb: cdns3: fix issue with rearming ISO OUT endpoint

[Greg Kroah-Hartman]

From: Pawel Laszczak <pawell@cadence.com>

[ Upstream commit b46a6b09fa056042a302b181a1941f0056944603 ]

ISO OUT endpoint is enabled during queuing first usb request
in transfer ring and disabled when TRBERR is reported by controller.
After TRBERR and before next transfer added to TR driver must again
reenable endpoint but does not.
To solve this issue during processing TRBERR event driver must
set the flag EP_UPDATE_EP_TRBADDR in priv_ep->flags field.

[PATCH 5.4 062/120] ALSA: hda/realtek: Add quirk for ASUS GA503R laptop

[Greg Kroah-Hartman]

From: Luke D. Jones <luke@ljones.dev>

commit ba1f818053b0668a1ce2fe86b840e81b592cc560 upstream.

The ASUS G15 2022 (GA503R) series laptop has the same node-to-DAC pairs
as early models and the G14, this includes bass speakers which are by
default mapped incorrectly to the 0x06 node.

Add a quirk to use the same DAC pairs as the G14.

[PATCH 5.4 063/120] ALSA: hda/realtek: Enable 4-speaker output Dell Precision 5530 laptop

[Greg Kroah-Hartman]

From: Callum Osmotherly <callum.osmotherly@gmail.com>

commit 1885ff13d4c42910b37a0e3f7c2f182520f4eed1 upstream.

Just as with the 5570 (and the other Dell laptops), this enables the two
subwoofer speakers on the Dell Precision 5530 together with the main
ones, significantly increasing the audio quality. I've tested this
myself on a 5530 and can confirm it's working as expected.

[PATCH 5.4 064/120] efi: libstub: check Shim mode using MokSBStateRT

[Greg Kroah-Hartman]

From: Ard Biesheuvel <ardb@kernel.org>

commit 5f56a74cc0a6d9b9f8ba89cea29cd7c4774cb2b1 upstream.

We currently check the MokSBState variable to decide whether we should
treat UEFI secure boot as being disabled, even if the firmware thinks
otherwise. This is used by shim to indicate that it is not checking
signatures on boot images. In the kernel, we use this to relax lockdown
policies.

However, in cases where shim is not even being used, we don't want this
variable to interfere with lockdown, given that the variable may be
non-volatile and therefore persist across a reboot. This means setting
it once will persistently disable lockdown checks on a given system.

So switch to the mirrored version of this variable, called MokSBStateRT,
which is supposed to be volatile, and this is something we can check.

[PATCH 5.4 065/120] mm/slub: fix to return errno if kmalloc() fails

[Greg Kroah-Hartman]

From: Chao Yu <chao.yu@oppo.com>

commit 7e9c323c52b379d261a72dc7bd38120a761a93cd upstream.

In create_unique_id(), kmalloc(, GFP_KERNEL) can fail due to
out-of-memory, if it fails, return errno correctly rather than
triggering panic via BUG_ON();

[PATCH 5.4 066/120] arm64: dts: rockchip: Pull up wlan wake# on Gru-Bob

[Greg Kroah-Hartman]

From: Brian Norris <briannorris@chromium.org>

[ Upstream commit e5467359a725de90b6b8d0dd865500f6373828ca ]

The Gru-Bob board does not have a pull-up resistor on its
WLAN_HOST_WAKE# pin, but Kevin does. The production/vendor kernel
specified the pin configuration correctly as a pull-up, but this didn't
get ported correctly to upstream.

This means Bob's WLAN_HOST_WAKE# pin is floating, causing inconsistent
wakeup behavior.

Note that bt_host_wake_l has a similar dynamic, but apparently the
upstream choice was to redundantly configure both internal and external
pull-up on Kevin (see the "Kevin has an external pull up" comment in
rk3399-gru.dtsi). This doesn't cause any functional problem, although
it's perhaps wasteful.

[PATCH 5.4 067/120] arm64: dts: rockchip: Set RK3399-Gru PCLK_EDP to 24 MHz

[Greg Kroah-Hartman]

From: zain wang <wzz@rock-chips.com>

[ Upstream commit 8123437cf46ea5a0f6ca5cb3c528d8b6db97b9c2 ]

We've found the AUX channel to be less reliable with PCLK_EDP at a
higher rate (typically 25 MHz). This is especially important on systems
with PSR-enabled panels (like Gru-Kevin), since we make heavy, constant
use of AUX.

According to Rockchip, using any rate other than 24 MHz can cause
"problems between syncing the PHY an PCLK", which leads to all sorts of
unreliabilities around register operations.

[PATCH 5.4 069/120] netfilter: nf_conntrack_sip: fix ct_sip_walk_headers

[Greg Kroah-Hartman]

From: Igor Ryzhov <iryzhov@nfware.com>

[ Upstream commit 39aebedeaaa95757f5c1f2ddb5f43fdddbf478ca ]

ct_sip_next_header and ct_sip_get_header return an absolute
value of matchoff, not a shift from current dataoff.
So dataoff should be assigned matchoff, not incremented by it.

This issue can be seen in the scenario when there are multiple
Contact headers and the first one is using a hostname and other headers
use IP addresses. In this case, ct_sip_walk_headers will work as follows:

The first ct_sip_get_header call to will find the first Contact header
but will return -1 as the header uses a hostname. But matchoff will
be changed to the offset of this header. After that, dataoff should be
set to matchoff, so that the next ct_sip_get_header call find the next
Contact header. But instead of assigning dataoff to matchoff, it is
incremented by it, which is not correct, as matchoff is an absolute
value of the offset. So on the next call to the ct_sip_get_header,
dataoff will be incorrect, and the next Contact header may not be
found at all.

CTCP messages should only be at the start of an IRC message, not
anywhere within it.

While the helper only decodes packes in the ORIGINAL direction, its
possible to make a client send a CTCP message back by empedding one into
a PING request.  As-is, thats enough to make the helper believe that it
saw a CTCP message.

The root cause is:
  1. packet_snd() only reset skb->mac_header when sock->type is SOCK_RAW
     and skb->protocol is not specified as in packet_parse_headers()

  2. packet_direct_xmit() doesn't reset skb->mac_header as dev_queue_xmit()

In this case, skb->mac_header is 65535 when ipvlan_xmit_mode_l2() is
called. So when ipvlan_xmit_mode_l2() gets mac header with eth_hdr() which
use "skb->head + skb->mac_header", out-of-bound access occurs.

This patch replaces eth_hdr() with skb_eth_hdr() in ipvlan_xmit_mode_l2()
and reset mac header in multicast to solve this out-of-bound bug.

[PATCH 5.4 074/120] net: team: Unsync device addresses on ndo_stop

[Greg Kroah-Hartman]

From: Benjamin Poirier <bpoirier@nvidia.com>

[ Upstream commit bd60234222b2fd5573526da7bcd422801f271f5f ]

Netdev drivers are expected to call dev_{uc,mc}_sync() in their
ndo_set_rx_mode method and dev_{uc,mc}_unsync() in their ndo_stop method.
This is mentioned in the kerneldoc for those dev_* functions.

The team driver calls dev_{uc,mc}_unsync() during ndo_uninit instead of
ndo_stop. This is ineffective because address lists (dev->{uc,mc}) have
already been emptied in unregister_netdevice_many() before ndo_uninit is
called. This mistake can result in addresses being leftover on former team
ports after a team device has been deleted; see test_LAG_cleanup() in the
last patch in this series.

Add unsync calls at their expected location, team_close().

v3:
* When adding or deleting a port, only sync/unsync addresses if the team
  device is up. In other cases, it is taken care of at the right time by
  ndo_open/ndo_set_rx_mode/ndo_stop.

[PATCH 5.4 076/120] MIPS: Loongson32: Fix PHY-mode being left unspecified

[Greg Kroah-Hartman]

From: Serge Semin <Sergey.Semin@baikalelectronics.ru>

[ Upstream commit e9f3f8f488005f6da3cfb66070706770ecaef747 ]

commit 0060c8783330 ("net: stmmac: implement support for passive mode
converters via dt") has changed the plat->interface field semantics from
containing the PHY-mode to specifying the MAC-PCS interface mode. Due to
that the loongson32 platform code will leave the phylink interface
uninitialized with the PHY-mode intended by the means of the actual
platform setup. The commit-author most likely has just missed the
arch-specific code to fix. Let's mend the Loongson32 platform code then by
assigning the PHY-mode to the phy_interface field of the STMMAC platform
data.

[PATCH 5.4 078/120] iavf: Fix set max MTU size with port VLAN and jumbo frames

[Greg Kroah-Hartman]

From: Michal Jaron <michalx.jaron@intel.com>

[ Upstream commit 399c98c4dc50b7eb7e9f24da7ffdda6f025676ef ]

After setting port VLAN and MTU to 9000 on VF with ice driver there
was an iavf error
"PF returned error -5 (IAVF_ERR_PARAM) to our request 6".

During queue configuration, VF's max packet size was set to
IAVF_MAX_RXBUFFER but on ice max frame size was smaller by VLAN_HLEN
due to making some space for port VLAN as VF is not aware whether it's
in a port VLAN. This mismatch in sizes caused ice to reject queue
configuration with ERR_PARAM error. Proper max_mtu is sent from ice PF
to VF with GET_VF_RESOURCES msg but VF does not look at this.

In iavf change max_frame from IAVF_MAX_RXBUFFER to max_mtu
received from pf with GET_VF_RESOURCES msg to make vf's
max_frame_size dependent from pf. Add check if received max_mtu is
not in eligible range then set it to IAVF_MAX_RXBUFFER.

[PATCH 5.4 080/120] i40e: Fix set max_tx_rate when it is lower than 1 Mbps

[Greg Kroah-Hartman]

From: Michal Jaron <michalx.jaron@intel.com>

[ Upstream commit 198eb7e1b81d8ba676d0f4f120c092032ae69a8e ]

While converting max_tx_rate from bytes to Mbps, this value was set to 0,
if the original value was lower than 125000 bytes (1 Mbps). This would
cause no transmission rate limiting to occur. This happened due to lack of
check of max_tx_rate against the 1 Mbps value for max_tx_rate and the
following division by 125000. Fix this issue by adding a helper
i40e_bw_bytes_to_mbits() which sets max_tx_rate to minimum usable value of
50 Mbps, if its value is less than 1 Mbps, otherwise do the required
conversion by dividing by 125000.

[PATCH 5.4 082/120] net/sched: taprio: avoid disabling offload when it was never enabled

[Greg Kroah-Hartman]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

[ Upstream commit db46e3a88a09c5cf7e505664d01da7238cd56c92 ]

In an incredibly strange API design decision, qdisc->destroy() gets
called even if qdisc->init() never succeeded, not exclusively since
commit 87b60cfacf9f ("net_sched: fix error recovery at qdisc creation"),
but apparently also earlier (in the case of qdisc_create_dflt()).

The taprio qdisc does not fully acknowledge this when it attempts full
offload, because it starts off with q->flags = TAPRIO_FLAGS_INVALID in
taprio_init(), then it replaces q->flags with TCA_TAPRIO_ATTR_FLAGS
parsed from netlink (in taprio_change(), tail called from taprio_init()).

But in taprio_destroy(), we call taprio_disable_offload(), and this
determines what to do based on FULL_OFFLOAD_IS_ENABLED(q->flags).

But looking at the implementation of FULL_OFFLOAD_IS_ENABLED()
(a bitwise check of bit 1 in q->flags), it is invalid to call this macro
on q->flags when it contains TAPRIO_FLAGS_INVALID, because that is set
to U32_MAX, and therefore FULL_OFFLOAD_IS_ENABLED() will return true on
an invalid set of flags.

As a result, it is possible to crash the kernel if user space forces an
error between setting q->flags = TAPRIO_FLAGS_INVALID, and the calling
of taprio_enable_offload(). This is because drivers do not expect the
offload to be disabled when it was never enabled.

The error that we force here is to attach taprio as a non-root qdisc,
but instead as child of an mqprio root qdisc:

$ tc qdisc add dev swp0 root handle 1: \

Fix this by keeping track of the operations we made, and undo the
offload only if we actually did it.

I've added "bool offloaded" inside a 4 byte hole between "int clockid"
and "atomic64_t picos_per_byte". Now the first cache line looks like
below:

[PATCH 5.4 083/120] net/sched: taprio: make qdisc_leaf() see the per-netdev-queue pfifo child qdiscs

[Greg Kroah-Hartman]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

[ Upstream commit 1461d212ab277d8bba1a753d33e9afe03d81f9d4 ]

taprio can only operate as root qdisc, and to that end, there exists the
following check in taprio_init(), just as in mqprio:

	if (sch->parent != TC_H_ROOT)
		return -EOPNOTSUPP;

And indeed, when we try to attach taprio to an mqprio child, it fails as
expected:

$ tc qdisc add dev swp0 root handle 1: mqprio num_tc 8 \
	map 0 1 2 3 4 5 6 7 \
	queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 hw 0
$ tc qdisc replace dev swp0 parent 1:2 taprio num_tc 8 \
	map 0 1 2 3 4 5 6 7 \
	queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 \
	base-time 0 sched-entry S 0x7f 990000 sched-entry S 0x80 100000 \
	flags 0x0 clockid CLOCK_TAI
Error: sch_taprio: Can only be attached as root qdisc.

(extack message added by me)

But when we try to attach a taprio child to a taprio root qdisc,
surprisingly it doesn't fail:

$ tc qdisc replace dev swp0 root handle 1: taprio num_tc 8 \
	map 0 1 2 3 4 5 6 7 queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 \
	base-time 0 sched-entry S 0x7f 990000 sched-entry S 0x80 100000 \
	flags 0x0 clockid CLOCK_TAI
$ tc qdisc replace dev swp0 parent 1:2 taprio num_tc 8 \
	map 0 1 2 3 4 5 6 7 \
	queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 \
	base-time 0 sched-entry S 0x7f 990000 sched-entry S 0x80 100000 \
	flags 0x0 clockid CLOCK_TAI

This is because tc_modify_qdisc() behaves differently when mqprio is
root, vs when taprio is root.

In the mqprio case, it finds the parent qdisc through
p = qdisc_lookup(dev, TC_H_MAJ(clid)), and then the child qdisc through
q = qdisc_leaf(p, clid). This leaf qdisc q has handle 0, so it is
ignored according to the comment right below ("It may be default qdisc,
ignore it"). As a result, tc_modify_qdisc() goes through the
qdisc_create() code path, and this gives taprio_init() a chance to check
for sch_parent != TC_H_ROOT and error out.

Whereas in the taprio case, the returned q = qdisc_leaf(p, clid) is
different. It is not the default qdisc created for each netdev queue
(both taprio and mqprio call qdisc_create_dflt() and keep them in
a private q->qdiscs[], or priv->qdiscs[], respectively). Instead, taprio
makes qdisc_leaf() return the _root_ qdisc, aka itself.

When taprio does that, tc_modify_qdisc() goes through the qdisc_change()
code path, because the qdisc layer never finds out about the child qdisc
of the root. And through the ->change() ops, taprio has no reason to
check whether its parent is root or not, just through ->init(), which is
not called.

The problem is the taprio_leaf() implementation. Even though code wise,
it does the exact same thing as mqprio_leaf() which it is copied from,
it works with different input data. This is because mqprio does not
attach itself (the root) to each device TX queue, but one of the default
qdiscs from its private array.

In fact, since commit 13511704f8d7 ("net: taprio offload: enforce qdisc
to netdev queue mapping"), taprio does this too, but just for the full
offload case. So if we tried to attach a taprio child to a fully
offloaded taprio root qdisc, it would properly fail too; just not to a
software root taprio.

To fix the problem, stop looking at the Qdisc that's attached to the TX
queue, and instead, always return the default qdiscs that we've
allocated (and to which we privately enqueue and dequeue, in software
scheduling mode).

Since Qdisc_class_ops :: leaf  is only called from tc_modify_qdisc(),
the risk of unforeseen side effects introduced by this change is
minimal.

[PATCH 5.4 087/120] perf kcore_copy: Do not check /proc/modules is unchanged

[Greg Kroah-Hartman]

From: Adrian Hunter <adrian.hunter@intel.com>

[ Upstream commit 5b427df27b94aec1312cace48a746782a0925c53 ]

/proc/kallsyms and /proc/modules are compared before and after the copy
in order to ensure no changes during the copy.

However /proc/modules also might change due to reference counts changing
even though that does not make any difference.

Any modules loaded or unloaded should be visible in changes to kallsyms,
so it is not necessary to check /proc/modules also anyway.

Remove the comparison checking that /proc/modules is unchanged.

[PATCH 5.4 088/120] net: sunhme: Fix packet reception for len < RX_COPY_THRESHOLD

[Greg Kroah-Hartman]

From: Sean Anderson <seanga2@gmail.com>

[ Upstream commit 878e2405710aacfeeb19364c300f38b7a9abfe8f ]

There is a separate receive path for small packets (under 256 bytes).
Instead of allocating a new dma-capable skb to be used for the next packet,
this path allocates a skb and copies the data into it (reusing the existing
sbk for the next packet). There are two bytes of junk data at the beginning
of every packet. I believe these are inserted in order to allow aligned DMA
and IP headers. We skip over them using skb_reserve. Before copying over
the data, we must use a barrier to ensure we see the whole packet. The
current code only synchronizes len bytes, starting from the beginning of
the packet, including the junk bytes. However, this leaves off the final
two bytes in the packet. Synchronize the whole packet.

To reproduce this problem, ping a HME with a payload size between 17 and
214

	$ ping -s 17 <hme_address>

which will complain rather loudly about the data mismatch. Small packets
(below 60 bytes on the wire) do not have this issue. I suspect this is
related to the padding added to increase the minimum packet size.

[PATCH 5.4 093/120] s390/dasd: fix Oops in dasd_alias_get_start_dev due to missing pavgroup

[Greg Kroah-Hartman]

From: Stefan Haberland <sth@linux.ibm.com>

commit db7ba07108a48c0f95b74fabbfd5d63e924f992d upstream.

Fix Oops in dasd_alias_get_start_dev() function caused by the pavgroup
pointer being NULL.

The pavgroup pointer is checked on the entrance of the function but
without the lcu->lock being held. Therefore there is a race window
between dasd_alias_get_start_dev() and _lcu_update() which sets
pavgroup to NULL with the lcu->lock held.

Fix by checking the pavgroup pointer with lcu->lock held.

problems in future.

 hyperv_drm 5620e0c7-8062-4dce-aeb7-520c7ef76171: [drm] Cannot request framebuffer, boot fb still active?

Note: "Cannot request framebuffer" is not a fatal error in
hyperv_setup_gen1() as the code assumes there's some other framebuffer
device there but we actually have some other PCI device (mlx4 in this
case) config space there!

The problem appears to be that vmbus_allocate_mmio() can use dedicated
framebuffer region to serve any MMIO request from any device. The
semantics one might assume of a parameter named "fb_overlap_ok"
aren't implemented because !fb_overlap_ok essentially has no effect.
The existing semantics are really "prefer_fb_overlap". This patch
implements the expected and needed semantics, which is to not allocate
from the frame buffer space when !fb_overlap_ok.

Note, Gen2 VMs are usually unaffected by the issue because
framebuffer region is already taken by EFI fb (in case kernel supports
it) but Gen1 VMs may have this region unclaimed by the time Hyper-V PCI
pass-through driver tries allocating MMIO space if Hyper-V DRM/FB drivers
load after it. Devices can be brought up in any sequence so let's
resolve the issue by always ignoring 'fb_mmio' region for non-FB
requests, even if the region is unclaimed.

[PATCH 5.4 097/120] gpio: ixp4xx: Make irqchip immutable

[Greg Kroah-Hartman]

From: Linus Walleij <linus.walleij@linaro.org>

[ Upstream commit 94e9bc73d85aa6ecfe249e985ff57abe0ab35f34 ]

This turns the IXP4xx GPIO irqchip into an immutable
irqchip, a bit different from the standard template due
to being hierarchical.

Tested on the IXP4xx which uses drivers/ata/pata_ixp4xx_cf.c
for a rootfs on compact flash with IRQs from this GPIO
block to the CF ATA controller.

[PATCH 5.4 099/120] drm/amd/display: Limit user regamma to a valid value

[Greg Kroah-Hartman]

From: Yao Wang1 <Yao.Wang1@amd.com>

[ Upstream commit 3601d620f22e37740cf73f8278eabf9f2aa19eb7 ]

[Why]
For HDR mode, we get total 512 tf_point and after switching to SDR mode
we actually get 400 tf_point and the rest of points(401~512) still use
dirty value from HDR mode. We should limit the rest of the points to max
value.

[How]
Limit the value when coordinates_x.x > 1, just like what we do in
translate_from_linear_space for other re-gamma build paths.

[PATCH 5.4 100/120] drm/rockchip: Fix return type of cdn_dp_connector_mode_valid

[Greg Kroah-Hartman]

From: Nathan Huckleberry <nhuck@google.com>

[ Upstream commit b0b9408f132623dc88e78adb5282f74e4b64bb57 ]

The mode_valid field in drm_connector_helper_funcs is expected to be of
type:
enum drm_mode_status (* mode_valid) (struct drm_connector *connector,
				     struct drm_display_mode *mode);

The mismatched return type breaks forward edge kCFI since the underlying
function definition does not match the function hook definition.

The return type of cdn_dp_connector_mode_valid should be changed from
int to enum drm_mode_status.

[PATCH 5.4 101/120] workqueue: dont skip lockdep work dependency in cancel_work_sync()

[Greg Kroah-Hartman]

From: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp>

[ Upstream commit c0feea594e058223973db94c1c32a830c9807c86 ]

Like Hillf Danton mentioned

  syzbot should have been able to catch cancel_work_sync() in work context
  by checking lockdep_map in __flush_work() for both flush and cancel.

in [1], being unable to report an obvious deadlock scenario shown below is
broken. From locking dependency perspective, sync version of cancel request
should behave as if flush request, for it waits for completion of work if
that work has already started execution.

  ----------
  #include <linux/module.h>
  #include <linux/sched.h>
  static DEFINE_MUTEX(mutex);
  static void work_fn(struct work_struct *work)
  {
    schedule_timeout_uninterruptible(HZ / 5);
    mutex_lock(&mutex);
    mutex_unlock(&mutex);
  }
  static DECLARE_WORK(work, work_fn);
  static int __init test_init(void)
  {
    schedule_work(&work);
    schedule_timeout_uninterruptible(HZ / 10);
    mutex_lock(&mutex);
    cancel_work_sync(&work);
    mutex_unlock(&mutex);
    return -EINVAL;
  }
  module_init(test_init);
  MODULE_LICENSE("GPL");
  ----------

The check this patch restores was added by commit 0976dfc1d0cd80a4
("workqueue: Catch more locking problems with flush_work()").

Then, lockdep's crossrelease feature was added by commit b09be676e0ff25bd
("locking/lockdep: Implement the 'crossrelease' feature"). As a result,
this check was once removed by commit fd1a5b04dfb899f8 ("workqueue: Remove
now redundant lock acquisitions wrt. workqueue flushes").

But lockdep's crossrelease feature was removed by commit e966eaeeb623f099
("locking/lockdep: Remove the cross-release locking checks"). At this
point, this check should have been restored.

Then, commit d6e89786bed977f3 ("workqueue: skip lockdep wq dependency in
cancel_work_sync()") introduced a boolean flag in order to distinguish
flush_work() and cancel_work_sync(), for checking "struct workqueue_struct"
dependency when called from cancel_work_sync() was causing false positives.

Then, commit 87915adc3f0acdf0 ("workqueue: re-add lockdep dependencies for
flushing") tried to restore "struct work_struct" dependency check, but by
error checked this boolean flag. Like an example shown above indicates,
"struct work_struct" dependency needs to be checked for both flush_work()
and cancel_work_sync().

[PATCH 5.4 102/120] ext4: fix bug in extents parsing when eh_entries == 0 and eh_depth > 0

[Greg Kroah-Hartman]

From: Luís Henriques <lhenriques@suse.de>

commit 29a5b8a137ac8eb410cc823653a29ac0e7b7e1b0 upstream.

When walking through an inode extents, the ext4_ext_binsearch_idx() function
assumes that the extent header has been previously validated.  However, there
are no checks that verify that the number of entries (eh->eh_entries) is
non-zero when depth is > 0.  And this will lead to problems because the
EXT_FIRST_INDEX() and EXT_LAST_INDEX() will return garbage and result in this:

From: Jan Kara <jack@suse.cz>

commit 613c5a85898d1cd44e68f28d65eccf64a8ace9cf upstream.

Currently the Orlov inode allocator searches for free inodes for a
directory only in flex block groups with at most inodes_per_group/16
more directory inodes than average per flex block group. However with
growing size of flex block group this becomes unnecessarily strict.
Scale allowed difference from average directory count per flex block
group with flex block group size as we do with other metrics.

[PATCH 5.4 104/120] xfs: replace -EIO with -EFSCORRUPTED for corrupt metadata

[Greg Kroah-Hartman]

From: "Darrick J. Wong" <darrick.wong@oracle.com>

commit c2414ad6e66ab96b867309454498f7fb29b7e855 upstream.

There are a few places where we return -EIO instead of -EFSCORRUPTED
when we find corrupt metadata.  Fix those places.

We should never see delalloc blocks for a pNFS layout, write or not.
Adjust the assert to check for that.

Range check the region counter when we're reassembling regions from log

kernel, but this isn't true any more so we have to make an explicit
error return.

[PATCH 5.4 108/120] xfs: attach dquots and reserve quota blocks during unwritten conversion

[Greg Kroah-Hartman]

From: "Darrick J. Wong" <darrick.wong@oracle.com>

commit 2815a16d7ff6230a8e37928829d221bb075aa160 upstream.

In xfs_iomap_write_unwritten, we need to ensure that dquots are attached
to the inode and quota blocks reserved so that we capture in the quota
counters any blocks allocated to handle a bmbt split.  This can happen
on the first unwritten extent conversion to a preallocated sparse file
on a fresh mount.

This was found by running generic/311 with quotas enabled.  The bug
seems to have been introduced in "[XFS] rework iocore infrastructure,
remove some code and make it more" from ~2002?

[PATCH 5.4 109/120] xfs: Fix deadlock between AGI and AGF when target_ip exists in xfs_rename()

[Greg Kroah-Hartman]

From: kaixuxia <xiakaixu1987@gmail.com>

commit 93597ae8dac0149b5c00b787cba6bf7ba213e666 upstream.

When target_ip exists in xfs_rename(), the xfs_dir_replace() call may
need to hold the AGF lock to allocate more blocks, and then invoking
the xfs_droplink() call to hold AGI lock to drop target_ip onto the
unlinked list, so we get the lock order AGF->AGI. This would break the
ordering constraint on AGI and AGF locking - inode allocation locks
the AGI, then can allocate a new extent for new inodes, locking the
AGF after the AGI.

In this patch we check whether the replace operation need more
blocks firstly. If so, acquire the agi lock firstly to preserve
locking order(AGI/AGF). Actually, the locking order problem only
occurs when we are locking the AGI/AGF of the same AG. For multiple
AGs the AGI lock will be released after the transaction committed.

[PATCH 5.4 111/120] xfs: constify the buffer pointer arguments to error functions

[Greg Kroah-Hartman]

From: "Darrick J. Wong" <darrick.wong@oracle.com>

commit d243b89a611e83dc97ce7102419360677a664076 upstream.

Some of the xfs error message functions take a pointer to a buffer that
will be dumped to the system log.  The logging functions don't change
the contents, so constify all the parameters.  This enables the next
patch to ensure that we log bad metadata when we encounter it.

[PATCH 5.4 112/120] xfs: always log corruption errors

[Greg Kroah-Hartman]

From: "Darrick J. Wong" <darrick.wong@oracle.com>

commit a5155b870d687de1a5f07e774b49b1e8ef0f6f50 upstream.

Make sure we log something to dmesg whenever we return -EFSCORRUPTED up
the call stack.

Fix a few places where we xlog_alloc_buffer a buffer, hit an error, and
then bail out without freeing the buffer.

[PATCH 5.4 114/120] xfs: stabilize insert range start boundary to avoid COW writeback race

[Greg Kroah-Hartman]

From: Brian Foster <bfoster@redhat.com>

commit d0c2204135a0cdbc607c94c481cf1ccb2f659aa7 upstream.

generic/522 (fsx) occasionally fails with a file corruption due to
an insert range operation. The primary characteristic of the
corruption is a misplaced insert range operation that differs from
the requested target offset. The reason for this behavior is a race
between the extent shift sequence of an insert range and a COW
writeback completion that causes a front merge with the first extent
in the shift.

The shift preparation function flushes and unmaps from the target
offset of the operation to the end of the file to ensure no
modifications can be made and page cache is invalidated before file
data is shifted. An insert range operation then splits the extent at
the target offset, if necessary, and begins to shift the start
offset of each extent starting from the end of the file to the start
offset. The shift sequence operates at extent level and so depends
on the preparation sequence to guarantee no changes can be made to
the target range during the shift. If the block immediately prior to
the target offset was dirty and shared, however, it can undergo
writeback and move from the COW fork to the data fork at any point
during the shift. If the block is contiguous with the block at the
start offset of the insert range, it can front merge and alter the
start offset of the extent. Once the shift sequence reaches the
target offset, it shifts based on the latest start offset and
silently changes the target offset of the operation and corrupts the
file.

To address this problem, update the shift preparation code to
stabilize the start boundary along with the full range of the
insert. Also update the existing corruption check to fail if any
extent is shifted with a start offset behind the target offset of
the insert range. This prevents insert from racing with COW
writeback completion and fails loudly in the event of an unexpected
extent shift.

[PATCH 5.4 115/120] xfs: use bitops interface for buf log item AIL flag check

[Greg Kroah-Hartman]

From: Brian Foster <bfoster@redhat.com>

commit 826f7e34130a4ce756138540170cbe935c537a47 upstream.

The xfs_log_item flags were converted to atomic bitops as of commit
22525c17ed ("xfs: log item flags are racy"). The assert check for
AIL presence in xfs_buf_item_relse() still uses the old value based
check. This likely went unnoticed as XFS_LI_IN_AIL evaluates to 0
and causes the assert to unconditionally pass. Fix up the check.

[PATCH 5.4 116/120] xfs: refactor agfl length computation function

[Greg Kroah-Hartman]

From: "Darrick J. Wong" <darrick.wong@oracle.com>

commit 1cac233cfe71f21e069705a4930c18e48d897be6 upstream.

Refactor xfs_alloc_min_freelist to accept a NULL @pag argument, in which
case it returns the largest possible minimum length.  This will be used
in an upcoming patch to compute the length of the AGFL at mkfs time.

[PATCH 5.4 117/120] xfs: split the sunit parameter update into two parts

[Greg Kroah-Hartman]

From: "Darrick J. Wong" <darrick.wong@oracle.com>

commit 4f5b1b3a8fa07dc8ecedfaf539b3deed8931a73e upstream.

If the administrator provided a sunit= mount option, we need to validate
the raw parameter, convert the mount option units (512b blocks) into the
internal unit (fs blocks), and then validate that the (now cooked)
parameter doesn't screw anything up on disk.  The incore inode geometry
computation can depend on the new sunit option, but a subsequent patch
will make validating the cooked value depends on the computed inode
geometry, so break the sunit update into two steps.

[PATCH 5.4 118/120] xfs: dont commit sunit/swidth updates to disk if that would cause repair failures

[Greg Kroah-Hartman]

From: "Darrick J. Wong" <darrick.wong@oracle.com>

commit 13eaec4b2adf2657b8167b67e27c97cc7314d923 upstream.

Alex Lyakas reported[1] that mounting an xfs filesystem with new sunit
and swidth values could cause xfs_repair to fail loudly.  The problem
here is that repair calculates the where mkfs should have allocated the
root inode, based on the superblock geometry.  The allocation decisions
depend on sunit, which means that we really can't go updating sunit if
it would lead to a subsequent repair failure on an otherwise correct
filesystem.

Port from xfs_repair some code that computes the location of the root
inode and teach mount to skip the ondisk update if it would cause
problems for repair.  Along the way we'll update the documentation,
provide a function for computing the minimum AGFL size instead of
open-coding it, and cut down some indenting in the mount code.

Note that we allow the mount to proceed (and new allocations will
reflect this new geometry) because we've never screened this kind of
thing before.  We'll have to wait for a new future incompat feature to
enforce correct behavior, alas.

Note that the geometry reporting always uses the superblock values, not
the incore ones, so that is what xfs_info and xfs_growfs will report.

[PATCH 5.4 119/120] xfs: fix an ABBA deadlock in xfs_rename

[Greg Kroah-Hartman]

From: "Darrick J. Wong" <darrick.wong@oracle.com>

commit 6da1b4b1ab36d80a3994fd4811c8381de10af604 upstream.

When overlayfs is running on top of xfs and the user unlinks a file in
the overlay, overlayfs will create a whiteout inode and ask xfs to
"rename" the whiteout file atop the one being unlinked.  If the file
being unlinked loses its one nlink, we then have to put the inode on the
unlinked list.

This requires us to grab the AGI buffer of the whiteout inode to take it
off the unlinked list (which is where whiteouts are created) and to grab
the AGI buffer of the file being deleted.  If the whiteout was created
in a higher numbered AG than the file being deleted, we'll lock the AGIs
in the wrong order and deadlock.

Therefore, grab all the AGI locks we think we'll need ahead of time, and
in order of increasing AG number per the locking rules.

We had that discussion[1], and concluded that none of these should be
backported to a kernel earlier than 5.19. 5.4 doesn't currently
contain the relevant infrastructure, nor should that infrastructure
should be backported either.

Can we *please* stop this?

I'd treat this a feature enabling rather than a fix.
It's small however, so if someone has a sent a backport request I'm fine
with it going in stable. If not, probably just unnecessary noise for stable.

Following patch caused this build break,

gpio: ixp4xx: Make irqchip immutable
[ Upstream commit 94e9bc73d85aa6ecfe249e985ff57abe0ab35f34 ]

This turns the IXP4xx GPIO irqchip into an immutable
irqchip, a bit different from the standard template due
to being hierarchical.

Tested on the IXP4xx which uses drivers/ata/pata_ixp4xx_cf.c
for a rootfs on compact flash with IRQs from this GPIO
block to the CF ATA controller.
