Passing string 'name' as the format specifier is potentially hazardous
because name could (although very unlikely to) have a format specifier
embedded in it causing issues when parsing the non-existent arguments
to these. Follow best practice by using the "%s" format string for
the string 'name'.

configuration of minimum shaper.
Increase the QEEC length to 0x20 as well: that's the length that the

mlxsw typically exercises, the firmware tolerated 0x1C-sized packets.

Fixes two problems introduced as early as
commit 03aef4b6dc12 ("Staging: comedi: add ni_mio_common code"):
(1) Ensures that the last four bits of NISTC_RTSI_TRIGB_OUT_REG register is
not unduly overwritten on e-series devices. On e-series devices, the
first three of the last four bits are reserved. The last bit defines
the output selection of the RGOUT0 pin, otherwise known as
RTSI_Sub_Selection. For m-series devices, these last four bits are
indeed used as the output selection of the RTSI7 pin (and the
RTSI_Sub_Selection bit for the RGOUT0 pin is moved to the
RTSI_Trig_Direction register.
(2) Allows all 4 RTSI_BRD lines to be treated as valid sources for RTSI
lines.
This patch also cleans up the ni_get_rtsi_routing command for readability.

A quirk in snd-usb-audio was added to automate setting sample rate to
4800k and remove the previously exposed nonfunctional microphone for
the Bowers & Wilkins PX:
commit 240a8af929c7c57dcde28682725b29cf8474e8e5
https://lore.kernel.org/patchwork/patch/919689/
However the headphones where updated shortly after that to remove the
unintentional microphone functionality. I guess because of this the
headphones now crash when connecting them via USB while the quirk is
active. Dmesg:
snd-usb-audio: probe of 2-3:1.0 failed with error -22

begin_current_label_crit_section() must run in sleepable context because
when label_is_stale() is true, aa_replace_current_label() runs, which uses
prepare_creds(), which can sleep.
Until now, the ptrace access check (which runs with a task lock held)
violated this rule.

powerpc: Use hardware RNG for arch_get_random_seed_* not arch_get_random_*
updated arch_get_random_[int|long]() to be NOPs, and moved the hardware
RNG backing to arch_get_random_seed_[int|long]() instead. However, it
failed to take into account that arch_get_random_int() was implemented
in terms of arch_get_random_long(), and so we ended up with a version
of the former that is essentially a NOP as well.
Fix this by calling arch_get_random_seed_long() from
arch_get_random_seed_int() instead.

commit 07d369857808b7e8e471bbbbb0074a6718f89b31 upstream.
Since there are some DIE which has only ranges instead of the
combination of entrypc/highpc, address verification must use
dwarf_haspc() instead of dwarf_entrypc/dwarf_highpc.
Also, the ranges only DIE will have a partial code in different section
(e.g. unlikely code will be in text.unlikely as "FUNC.cold" symbol). In
that case, we can not use dwarf_entrypc() or die_entrypc(), because the
offset from original DIE can be a minus value.
Instead, this simply gets the symbol and offset from symtab.
Without this patch;
# perf probe -D clear_tasks_mm_cpumask:1

The member hba->pcidev may be used after its reference is dropped. Move the
put function to where it is never used to avoid potential use after free
issues.

commit 394440d469413fa9b74f88a11f144d76017221f2 upstream.
Commit 60e4cf67a58 (reiserfs: fix extended attributes on the root
directory) introduced a regression open_xa_root started returning
-EOPNOTSUPP but it was not handled properly in reiserfs_for_each_xattr.
When the reiserfs module is built without CONFIG_REISERFS_FS_XATTR,
deleting an inode would result in a warning and chowning an inode
would also result in a warning and then fail to complete.
With CONFIG_REISERFS_FS_XATTR enabled, the xattr root would always be
present for read-write operations.
This commit handles -EOPNOSUPP in the same way -ENODATA is handled.

commit 54fb3fe0f211d4729a2551cf9497bd612189af9d upstream.
This reverts commit 193d00a2b35ee3353813b4006a18131122087205.
Commit 951d48855d86 ("of: Make of_dma_get_range() work on bus nodes")
reworked the logic such that of_dma_get_range() works correctly
starting from a bus node containing "dma-ranges".
Since on Juno we don't have a SoC level bus node and "dma-ranges" is
present only in the root node, we get the following error:
OF: translation of DMA address(0) to CPU address failed node(/sram@2e000000)
OF: translation of DMA address(0) to CPU address failed node(/uart@7ff80000)
...
OF: translation of DMA address(0) to CPU address failed node(/mhu@2b1f0000)
OF: translation of DMA address(0) to CPU address failed node(/iommu@2b600000)
OF: translation of DMA address(0) to CPU address failed node(/iommu@2b600000)
OF: translation of DMA address(0) to CPU address failed node(/iommu@2b600000)
So let's fix it by dropping the "dma-ranges" property for now. This
should be fine since it doesn't represent any kind of device-visible
restriction; it was only there for completeness, and we've since given
in to the assumption that missing "dma-ranges" implies a 1:1 mapping
anyway.
We can add it later with a proper SoC bus node and moving all the
devices that belong there along with the "dma-ranges" if required.

[ Upstream commit e176b1ba476cf36f723cfcc7a9e57f3cb47dec70 ]
When the packet pointed to by retransmit_skb_hint is unlinked by ACK,
retransmit_skb_hint will be set to NULL in tcp_clean_rtx_queue().
If packet loss is detected at this time, retransmit_skb_hint will be set
to point to the current packet loss in tcp_verify_retransmit_hint(),
then the packets that were previously marked lost but not retransmitted
due to the restriction of cwnd will be skipped and cannot be
retransmitted.
To fix this, when retransmit_skb_hint is NULL, retransmit_skb_hint can
be reset only after all marked lost packets are retransmitted
(retrans_out >= lost_out), otherwise we need to traverse from
tcp_rtx_queue_head in tcp_xmit_retransmit_queue().

There is a bug in ptp_clock_unregister(), where ptp_cleanup_pin_groups()
first frees ptp->pin_{,dev_}attr, but then posix_clock_unregister() needs
them to destroy a related sysfs device.
These functions can not be just swapped, as posix_clock_unregister() frees
ptp which is needed in the ptp_cleanup_pin_groups(). Fix this by calling
ptp_cleanup_pin_groups() in ptp_clock_release(), right before ptp is freed.
This makes this patch fix an UAF bug in a patch which fixes an UAF bug.

For localy generated packets, we can use netif_set_gso_max_size()

Note that forwarded packets could still hit the issue,
so a complete fix might require implementing .ndo_features_check
for this driver, forcing a software segmentation if the size

When there is not enough memory and napi_alloc_skb() return NULL,
the HNS driver will print error message, and than try again, if
the memory is not enough for a while, huge error message and the
retry operation will cause soft lockup.
When napi_alloc_skb() return NULL because of no memory, we can
get a warn_alloc() call trace, so this patch deletes the error
message. We already use polling mode to handle irq, but the
retry operation will render the polling weight inactive, this
patch just return budget when the rx is not completed to avoid
dead loop.

commit 4cc4a1708903f404d2ca0dfde30e71e052c6cbc9 upstream.
The distributed arp table is using a DHT to store and retrieve MAC address
information for an IP address. This is done using unicast messages to
selected peers. The potential peers are looked up using the IP address and
the VID.
While the IP address is always stored in big endian byte order, this is not
the case of the VID. It can (depending on the host system) either be big
endian or little endian. The host must therefore always convert it to big
endian to ensure that all devices calculate the same peers for the same
lookup data.

The driver was doing a synchronous uninterruptible bulk-transfer without
using a timeout. This could lead to the driver hanging on probe due to a
malfunctioning (or malicious) device until the device is physically
disconnected. While sleeping in probe the driver prevents other devices
connected to the same hub from being added to (or removed from) the bus.
An arbitrary limit of five seconds should be more than enough.
