btrfs: zlib: fix the folio leak on S390 hardware acceleration
btrfs: do not strictly require dirty metadata threshold for metadata writepages
This patch enhances GSO segment handling by properly checking
the SKB_GSO_DODGY flag for frag_list GSO packets, addressing
low throughput issues observed when a station accesses IPv4
servers via hotspots with an IPv6-only upstream interface.
Specifically, it fixes a bug in GSO segmentation when forwarding
GRO packets containing a frag_list. The function skb_segment_list
cannot correctly process GRO skbs that have been converted by XLAT,
since XLAT only translates the header of the head skb. Consequently,
skbs in the frag_list may remain untranslated, resulting in protocol
inconsistencies and reduced throughput.
To address this, the patch explicitly sets the SKB_GSO_DODGY flag
for GSO packets in XLAT's IPv4/IPv6 protocol translation helpers
(bpf_skb_proto_4_to_6 and bpf_skb_proto_6_to_4). This marks GSO
packets as potentially modified after protocol translation. As a
result, GSO segmentation will avoid using skb_segment_list and
instead falls back to skb_segment for packets with the SKB_GSO_DODGY
flag. This ensures that only safe and fully translated frag_list
packets are processed by skb_segment_list, resolving protocol
inconsistencies and improving throughput when forwarding GRO packets
converted by XLAT.

TID-To-Link Mapping (TTLM) elements do not contain any link mapping
presence indicator if a default mapping is used and parsing needs to be
skipped.
Note that access points should not explicitly report an advertised TTLM
with a default mapping as that is the implied mapping if the element is
not included, this is even the case when switching back to the default
mapping. However, mac80211 would incorrectly parse the frame and would
also read one byte beyond the end of the element.

mptcp: avoid dup NL events and propagate error
Here are two fixes affecting the MPTCP Netlink events with their tests:
- Patches 1 & 2: a subflow closed NL event was visible multiple times in
some specific conditions. A fix for v5.12.
- Patches 3 & 4: subflow closed NL events never contained the error
code, even when expected. A fix for v5.11.
Plus an extra fix:
- Patch 5: fix a false positive with the "signal addresses race test"
subtest when validating the MPTCP Join selftest on a v5.15.y stable
kernel.

When running this mptcp_join.sh selftest on older kernel versions not
supporting local endpoints tracking, this test fails because 3 MP_JOIN
ACKs have been received, while only 2 were expected.
It is not clear why only 2 MP_JOIN ACKs were expected on old kernel
versions, while 3 MP_JOIN SYN and SYN+ACK were expected. When testing on
the v5.15.197 kernel, 3 MP_JOIN ACKs are seen, which is also what is
expected in the selftests included in this kernel version, see commit
f4480eaad4 ("selftests: mptcp: add missing join check").
Switch the expected MP_JOIN ACKs to 3. While at it, move this
chk_join_nr helper out of the special condition for older kernel
versions as it is now the same as with more recent ones. Also, invert
the condition to be more logical: what's expected on newer kernel
versions having such helper first.

This validates the previous commit: subflow closed events should contain
an error field when a subflow got closed with an error, e.g. reset or

For this test, the chk_evt_nr helper has been extended to check
attributes in the matched events.
In this test, the 2 subflow closed events should have an error.

Some subflow socket errors need to be reported to the MPTCP socket: the
initial subflow connect (MP_CAPABLE), and the ones from the fallback
sockets. The others are not propagated.
The issue is that sock_error() was used to retrieve the error, which was
also resetting the sk_err field. Because of that, when notifying the
userspace about subflow close events later on from the MPTCP worker, the
ssk->sk_err field was always 0.
Now, the error (sk_err) is only reset when propagating it to the msk.

This validates the previous commit: subflow closed events are re-sent
with less info when the initial subflow is disconnected after an error
and each time a subflow is closed after that.
In this new test, the userspace PM is involved because that's how it was
discovered, but it is not specific to it. The initial subflow is
terminated with a RESET, and that will cause the subflow disconnect.
Then, a new subflow is initiated, but also got rejected, which cause a
second subflow closed event, but not a third one.
While at it, in case of failure to get the expected amount of events,
the events are printed.

In case of subflow disconnect(), which can also happen with the first
subflow in case of errors like timeout or reset, mptcp_subflow_ctx_reset
will reset most fields from the mptcp_subflow_context structure,
including close_event_done. Then, when another subflow is closed, yet
another SUB_CLOSED event for the disconnected initial subflow is sent.
Because of the previous reset, there are no source address and
destination port.
A solution is then to also check the subflow's local id: it shouldn't be
negative anyway.
Another solution would be not to reset subflow->close_event_done at
disconnect time, but when reused. But then, probably the whole reset
could be done when being reused. Let's not change this logic, similar
to TCP with tcp_disconnect().

Commit a5e400a985 ("net/mlx5e: Honor user choice of IPsec replay
window size") introduced logic to setup the ESN replay window size.
This logic is only valid for packet offload.
However, the check to skip this block only covered outbound offloads.
It was not skipped for crypto offload, causing it to fall through to
the new switch statement and trigger its WARN_ON default case (for
instance, if a window larger than 256 bits was configured).
Fix this by amending the condition to also skip the replay window
setup if the offload type is not XFRM_DEV_OFFLOAD_PACKET.

Since the commit 25c6a5ab15 ("net: phy: micrel: Dynamically control
external clock of KSZ PHY"), the clock of Micrel PHY has been enabled
by phy_driver::resume() and disabled by phy_driver::suspend(). However,
devm_clk_get_optional_enabled() is used in kszphy_probe(), so the clock
will automatically be disabled when the device is unbound from the bus.
Therefore, this could cause the clock to be disabled twice, resulting
in clk driver warnings.
For example, this issue can be reproduced on i.MX6ULL platform, and we
can see the following logs when removing the FEC MAC drivers.

[ 110.099782] fec_drv_remove from device_release_driver_internal+0x17c/0x1f4
After analyzing the process of removing the FEC driver, as shown below,
it can be seen that the clock was disabled twice by the PHY driver.
fec_drv_remove()
--> fec_enet_close()
--> phy_stop()
--> phy_suspend()
--> kszphy_suspend() #1 The clock is disabled
--> fec_enet_mii_remove()
--> mdiobus_unregister()
--> phy_mdio_device_remove()
--> device_del()
--> devm_clk_release() #2 The clock is disabled again
Therefore, devm_clk_get_optional() is used to fix the above issue. And
to avoid the issue mentioned by the commit 9853294627 ("net: phy:
micrel: use devm_clk_get_optional_enabled for the rmii-ref clock"), the
clock is enabled by clk_prepare_enable() to get the correct clock rate.

GPIO Address Space handler gets a pointer to the in or out value.
This value is supposed to be at least 64-bit, but it's not limited
to be exactly 64-bit. When ACPI tables are being parsed, for
the bigger Connection():s ACPICA creates a Buffer instead of regular
Integer object. The Buffer exists as long as Namespace holds
the certain Connection(). Hence we can access the necessary bits
without worrying. On the other hand, the left shift, used in
the code, is limited by 31 (on 32-bit platforms) and otherwise
considered to be Undefined Behaviour. Also the code uses only
the first 64-bit word for the value, and anything bigger than 63
will be also subject to UB. Fix all this by modifying the code
to correctly set or clear the respective bit in the bitmap constructed
of 64-bit words.

The brcmstb_gpio_hwirq_to_bank() function was designed to
accommodate the downward numbering of dynamic GPIOs by
traversing the bank list in the reverse order. However, the
dynamic numbering has changed to increment upward which can
produce an incorrect mapping.
The function is modified to no longer assume an ordering of
the list to accommodate either option.

Commit 11a78b7944 ("ARM: OMAP: MPUIO wake updates") registers the
omap_mpuio_driver from omap_mpuio_init(), which is called from
omap_gpio_probe().
However, it neither makes sense to register drivers from probe()
callbacks of other drivers, nor does the driver core allow registering
drivers with a device lock already being held.
The latter was revealed by commit dc23806a7c ("driver core: enforce
device_lock for driver_match_device()") leading to a potential deadlock
condition described in [1].
Additionally, the omap_mpuio_driver is never unregistered from the
driver core, even if the module is unloaded.
Hence, register the omap_mpuio_driver from the module initcall and
unregister it in module_exit().

If timestamping is supported, GVE reads the clock during probe,
which can fail for various reasons. Previously, this failure would
abort the driver probe, rendering the device unusable. This behavior
has been observed on production GCP VMs, causing driver initialization
to fail completely.
This patch allows the driver to degrade gracefully. If gve_init_clock()
fails, it logs a warning and continues loading the driver without PTP
support.

The driver's ndo_get_stats64 callback is only reporting mlx5 counters,
without accounting for the netdev stats, causing errors from the network
stack to be invisible in statistics.
Add netdev_stats_to_stats64() call to first populate the counters, then
add mlx5 counters on top, ensuring both are accounted for (where
appropriate).

It is possible to unbind the uplink ETH driver while the E-Switch is
in switchdev mode. This leads to netdevice reference counting issues[1],
as the driver removal path was not designed to clean up from this state.
During uplink ETH driver removal (_mlx5e_remove), the code now waits for
any concurrent E-Switch mode transition to finish. It then removes the
REPs auxiliary device, if exists. This ensures a graceful cleanup.
