The AHCI specification version 1.3.1 section 8.3.1.4 (Software
Requirements and Precedence) states that:
If CAP.SSC or CAP.PSC is cleared to ‘0’, software should disable
device-initiated power management by issuing the appropriate SET
FEATURES command to the device.
To satisfy this constraint and force ata_dev_configure to disable the
device DIPM feature, modify ahci_update_initial_lpm_policy() to set the
ATA_FLAG_NO_DIPM flag on ports that have a host with either the
ATA_HOST_NO_PART flag set or the ATA_HOST_NO_SSC flag set.

In ata_eh_revalidate_and_attach(), a link LPM policy is always
set to ATA_LPM_MAX_POWER before calling ata_dev_revalidate() to ensure
that the call to ata_phys_link_offline() does not return true, thus
causing an unnecessary device reset. This change was introduced
with commit 71d7b6e51a ("ata: libata-eh: avoid needless hard reset
when revalidating link").
However, setting the link LPM policy to ATA_LPM_MAX_POWER may be
visible only after some time, depending on the power state the link was
in. E.g. transitioning out of the Partial state should take no longer
than a few microseconds, but transitioning out of the Slumber or
DevSleep state may take several milliseconds. So despite the changes
introduced with commit 71d7b6e51a ("ata: libata-eh: avoid needless
hard reset when revalidating link"), we can still endup with
ata_phys_link_offline() seeing a link SCR_STATUS register signaling that
the device is present (DET is equal to 1h) but that the link PHY is
still in a low power mode (e.g. IPM is 2h, signaling "Interface in
Partial power management state"). In such cases, ata_phys_link_offline()
returns true, causing an EIO return for ata_eh_revalidate_and_attach()
and a device reset.
Avoid such unnecessary device resets by introducing a relaxed version
of the link offline test implemented by ata_phys_link_offline() with
the new helper function ata_eh_link_established(). This functions
returns true if for the link SCR_STATUS register we see that:
- A device is still present, that is, the DET field is 1h (Device
presence detected but Phy communication not established) or 3h
(Device presence detected and Phy communication established).
- Communication is established, that is, the IPM field is not 0h,
indicating that the PHY is online or in a low power state.

If the port of a device does not support Device Initiated Power
Management (DIPM), that is, the port is flagged with ATA_FLAG_NO_DIPM,
the DIPM feature of a device should not be used. Though DIPM is disabled
by default on a device, the "Software Settings Preservation feature"
may keep DIPM enabled or DIPM may have been enabled by the system
firmware.
Introduce the function ata_dev_config_lpm() to always disable DIPM on a
device that supports this feature if the port of the device is flagged
with ATA_FLAG_NO_DIPM. ata_dev_config_lpm() is called from
ata_dev_configure(), ensuring that a device DIPM feature is disabled

Prefer the register read specific wait function over i915 wait_for_us().
The existing condition is quite complicated. Simplify by checking for

requesters in case of timeouts, should one have popped up during the

requesters show up *during* the wait, but we're talking about 1 ms so
shouldn't be an issue.

The issue originates when Strongswan initiates an XFRM_MSG_ALLOCSPI
Netlink message, which triggers the kernel function xfrm_alloc_spi().
This function is expected to ensure uniqueness of the Security Parameter
Index (SPI) for inbound Security Associations (SAs). However, it can
return success even when the requested SPI is already in use, leading
to duplicate SPIs assigned to multiple inbound SAs, differentiated
only by their destination addresses.
This behavior causes inconsistencies during SPI lookups for inbound packets.
Since the lookup may return an arbitrary SA among those with the same SPI,
packet processing can fail, resulting in packet drops.
According to RFC 4301 section 4.4.2 , for inbound processing a unicast SA
is uniquely identified by the SPI and optionally protocol.
Reproducing the Issue Reliably:
To consistently reproduce the problem, restrict the available SPI range in
charon.conf : spi_min = 0x10000000 spi_max = 0x10000002
This limits the system to only 2 usable SPI values.
Next, create more than 2 Child SA. each using unique pair of src/dst address.
As soon as the 3rd Child SA is initiated, it will be assigned a duplicate
SPI, since the SPI pool is already exhausted.
With a narrow SPI range, the issue is consistently reproducible.
With a broader/default range, it becomes rare and unpredictable.
Current implementation:
xfrm_spi_hash() lookup function computes hash using daddr, proto, and family.
So if two SAs have the same SPI but different destination addresses, then
they will:
a. Hash into different buckets
b. Be stored in different linked lists (byspi + h)
c. Not be seen in the same hlist_for_each_entry_rcu() iteration.
As a result, the lookup will result in NULL and kernel allows that Duplicate SPI
Proposed Change:
xfrm_state_lookup_spi_proto() does a truly global search - across all states,
regardless of hash bucket and matches SPI and proto.

This shows up when running traffic over ipcomp using transport mode.
After being reinjected, packets are dropped because the header isn't

This is not only a cosmetic change because the section mismatch checks
(implemented in scripts/mod/modpost.c) also depend on the object's name
and for drivers the checks are stricter than for ops.
However aq_pci_driver also passes the stricter checks just fine, so no
further changes needed.
The cheating^Wmisleading name was introduced in commit 97bde5c4f9
("net: ethernet: aquantia: Support for NIC-specific code")

If the user reinitializes the network interface, the PHY will reinitialize,
and the CKO settings will revert to their initial configuration(be enabled).
To prevent CKO from being re-enabled,
en8811h_clk_restore_context and en8811h_resume were added
to ensure the CKO settings remain correct.

This is no longer available in GTK 3. Use "tooltip-text" instead.
Also reword "Goes up of one level" to "Goes up one level" while I am
here.

'struct devlink_region_ops' and 'struct hellcreek_fdb_entry' are not
modified in this driver.
Constifying these structures moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.
On a x86_64, with allmodconfig:
