0863dedf58 PM: hibernate: Remove register_nosave_region_late()
[ Upstream commit 33569ef3c754a82010f266b7b938a66a3ccf90a4 ]

It is an unused wrapper forcing kmalloc allocation for registering
nosave regions. Also, rename __register_nosave_region() to
register_nosave_region() now that there is no need for disambiguation.

[ Upstream commit a861790afaa8b6369eee8a88c5d5d73f5799c0c6 ]

iscsit_tpg_check_network_portal() has nested for_each loops and is supposed
to return true when a match is found. However, the tpg loop will still
continue after existing the tpg_np loop. If this tpg_np is not the last the

Break the outer loop after finding a match and make sure the np under each

When adding a tc rule with a qdisc kind that is not supported or not
compiled into the kernel, the kernel emits the following error: "Error:
Specified qdisc not found.". Found via tdc testing when ETS qdisc was not
compiled in and it was not obvious right away what the message meant
without looking at the kernel code.

Change the error message to be more explicit and say the qdisc kind is

Ensure that a client cannot specify a WRITE range that falls in a
byte range outside what the kernel's internal types (such as loff_t,
which is signed) can represent. The kiocb iterators, invoked in
nfsd_vfs_write(), should properly limit write operations to within
the underlying file system's s_maxbytes.

09295a9893 net: phy: marvell: Fix MDI-x polarity setting in 88e1118-compatible PHYs
commit aec12836e7196e4d360b2cbf20cf7aa5139ad2ec upstream.

When setting up autonegotiation for 88E1118R and compatible PHYs,
a software reset of PHY is issued before setting up polarity.
This is incorrect as changes of MDI Crossover Mode bits are
disruptive to the normal operation and must be followed by a
software reset to take effect. Let's patch m88e1118_config_aneg()
to fix the issue mentioned before by invoking software reset
of the PHY just after setting up MDI-x polarity.

f84d17e6dd net: phy: marvell: Fix RGMII Tx/Rx delays setting in 88e1121-compatible PHYs
commit fe4f57bf7b585dca58f1496c4e2481ecbae18126 upstream.

It is mandatory for a software to issue a reset upon modifying RGMII
Receive Timing Control and RGMII Transmit Timing Control bit fields of MAC
Specific Control register 2 (page 2, register 21) otherwise the changes
won't be perceived by the PHY (the same is applicable for a lot of other
registers). Not setting the RGMII delays on the platforms that imply it'
being done on the PHY side will consequently cause the traffic loss. We
discovered that the denoted soft-reset is missing in the
m88e1121_config_aneg() method for the case if the RGMII delays are
modified but the MDIx polarity isn't changed or the auto-negotiation is
left enabled, thus causing the traffic loss on our platform with Marvell
Alaska 88E1510 installed. Let's fix that by issuing the soft-reset if the
delays have been actually set in the m88e1121_config_aneg_rgmii_delays()
method.

Therefore, it should be better to check it and return the error if

And since the sdhci_setup_host() has already checked the return value of

89e51f2ab8 ima: Allow template selection with ima_template[_fmt]= after ima_hash=
commit bb8e52e4906f148c2faf6656b5106cf7233e9301 upstream.

Commit c2426d2ad5027 ("ima: added support for new kernel cmdline parameter
ima_template_fmt") introduced an additional check on the ima_template
variable to avoid multiple template selection.

Unfortunately, ima_template could be also set by the setup function of the
ima_hash= parameter, when it calls ima_template_desc_current(). This causes
attempts to choose a new template with ima_template= or with
ima_template_fmt=, after ima_hash=, to be ignored.

Achieve the goal of the commit mentioned with the new static variable
template_setup_done, so that template selection requests after ima_hash=
are not ignored.

Finally, call ima_init_template_list(), if not already done, to initialize
the list of templates before lookup_template_desc() is called.

The function tipc_mon_rcv() allows a node to receive and process
domain_record structs from peer nodes to track their views of the
network topology.

This patch verifies that the number of members in a received domain
record does not exceed the limit defined by MAX_MON_DOMAIN, something
that may otherwise lead to a stack overflow.

tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where
we are reading a 32 bit message data length field into a uint16.  To
avert any risk of bit overflow, we add an extra sanity check for this in
that function.  We cannot see that happen with the current code, but
future designers being unaware of this risk, may introduce it by
allowing delivery of very large (> 64k) sk buffers from the bearer
layer.  This potential problem was identified by Eric Dumazet.

This fixes CVE-2022-0435

3a0a7ec557 moxart: fix potential use-after-free on remove path
commit bd2db32e7c3e35bd4d9b8bbff689434a50893546 upstream.

It was reported that the mmc host structure could be accessed after it
was freed in moxart_remove(), so fix this by saving the base register of
the device and using it instead of the pointer dereference.

commit 2bdfd2825c9662463371e6691b1a794e97fa36b4 upstream.

It was found that a "suspicious RCU usage" lockdep warning was issued
with the rcu_read_lock() call in update_sibling_cpumasks().  It is
because the update_cpumasks_hier() function may sleep. So we have
to release the RCU lock, call update_cpumasks_hier() and reacquire
it afterward.

Also add a percpu_rwsem_assert_held() in update_sibling_cpumasks()
instead of stating that in the comment.

commit 897026aaa73eb2517dfea8d147f20ddb0b813044 upstream.

While running "./check -I 200 generic/475" it sometimes gives below
kernel BUG(). Ideally we should not call ext4_write_inline_data() if
ext4_create_inline_data() has failed.

<log snip>
[73131.453234] kernel BUG at fs/ext4/inline.c:223!

This patch handles the error and prints out a emergency msg saying potential

commit e958b5884725dac86d36c1e7afe5a55f31feb0b2 upstream.

This patch is based on one in the Xilinx kernel tree, "ASoc: xlnx: Make
buffer bytes multiple of period bytes" by Devarsh Thakkar. The same
issue exists in the mainline version of the driver. The original
patch description is as follows:

"The Xilinx Audio Formatter IP has a constraint on period
bytes to be multiple of 64. This leads to driver changing
the period size to suitable frames such that period bytes
are multiple of 64.

Now since period bytes and period size are updated but not
the buffer bytes, this may make the buffer bytes unaligned
and not multiple of period bytes.

When this happens we hear popping noise as while DMA is being
done the buffer bytes are not enough to complete DMA access
for last period of frame within the application buffer boundary.

To avoid this, align buffer bytes too as multiple of 64, and
set another constraint to always enforce number of periods as
integer. Now since, there is already a rule in alsa core
to enforce Buffer size = Number of Periods * Period Size
this automatically aligns buffer bytes as multiple of period
bytes."

Even if protected from preemption and interrupts, a small time window
remains when the 2 register reads could return inconsistent values,
each time the "seconds" register changes. This could lead to an about
1-second error in the reported time.

9afc028640 net: stmmac: dump gmac4 DMA registers correctly
commit 7af037c39b600bac2c716dd1228e8ddbe149573f upstream.

Unlike gmac100, gmac1000, gmac4 has 27 DMA registers and they are
located at DMA_CHAN_BASE_ADDR (0x1100). In order for ethtool to dump
gmac4 DMA registers correctly, this commit checks if a net_device has
gmac4 and uses different logic to dump its DMA registers.

This fixes the following KASAN warning, which can normally be triggered

77454c9ada net: macsec: Verify that send_sci is on when setting Tx sci explicitly
commit d0cfa548dbde354de986911d3913897b5448faad upstream.

When setting Tx sci explicit, the Rx side is expected to use this
sci and not recalculate it from the packet.However, in case of Tx sci
is explicit and send_sci is off, the receiver is wrongly recalculate
the sci from the source MAC address which most likely be different
than the explicit sci.

Fix by preventing such configuration when macsec newlink is established
and return EINVAL error code on such cases.

Returning -1 does not indicate anything useful.

Use a standard and meaningful error code instead.

commit 621b24b09eb61c63f262da0c9c5f0e93348897e5 upstream.

Upon error the ieee802154_xmit_complete() helper is not called. Only
ieee802154_wake_queue() is called manually. We then leak the skb
structure.

Free the skb structure upon error before returning.

These periods are expressed in time units (microseconds) while 40 and 12
are the number of symbol durations these periods will last. We need to
multiply them both with phy->symbol_duration in order to get these
values in microseconds.

commit 1293fccc9e892712d910ec96079d3717307f1d2d upstream.

Drivers are expected to set the PHY current_channel and current_page
according to their default state. The hwsim driver is advertising being
configured on channel 13 by default but that is not reflected in its own
internal pib structure. In order to ensure that this driver consider the
current channel as being 13 internally, we at least need to set the
pib->channel field to 13.

commit e937440f7fc444a3e3f1fb75ea65292d6f433a44 upstream.

This check misses checking for  platform_get_irq()'s call and may passes
the negative error codes to devm_request_irq(), which takes unsigned IRQ #,
causing it to fail with -EINVAL, overriding an original error code.
Stop calling devm_request_irq() with invalid IRQ #s.

In some case, like after a transfer timeout, master->cur_msg pointer
is NULL which led to a kernel crash when trying to use master->cur_msg->spi.
mtk_spi_can_dma(), pointed by master->can_dma, doesn't use this parameter
avoid the problem by setting NULL as second parameter.

Apply only valid chip select value. This change fixes case where chip
select is set to initial value of '-1' during probe and  PM supend and
subsequent resume can try to use the value with undefined behaviour.
Also in case where gpio based chip select, the check in
bcm_qspi_chip_select() shall prevent undefined behaviour on resume.
