The sockopt test invokes test__start_subtest and then unconditionally
asserts the success. That means that even if deny-listed, any test will
still run and potentially fail.
Evaluate the return value of test__start_subtest() to achieve the
desired behavior, as other tests do.

Seems like that extra bpf_capable() check in BPF_MAP_FREEZE handler was
unintentionally left when we switched to a model that all BPF map
operations should be allowed regardless of CAP_BPF (or any other
capabilities), as long as process got BPF map FD somehow.
This patch replaces bpf_capable() check in BPF_MAP_FREEZE handler with
writeable access check, given conceptually freezing the map is modifying
it: map becomes unmodifiable for subsequent updates.

A future change will convert the DMA API implementation from the
architecture specific arch/s390/pci/pci_dma.c to using the common code
drivers/iommu/dma-iommu.c which the utilizes the same IOMMU hardware
through the s390-iommu driver. Unlike the s390 specific DMA API this
requires devices to correctly set the coherent mask to be allowed to use
IOVAs >2^32 in dma_alloc_coherent(). This was however not done for ISM
devices. ISM requires such addresses since currently the DMA aperture
for PCI devices starts at 2^32 and all calls to dma_alloc_coherent()
would thus fail.

Antoine Tenart says:
====================
net: tcp: make txhash use consistent for IPv4
Series is divided in two parts. First two commits make the txhash (used
for the skb hash in TCP) to be consistent for all IPv4/TCP packets (IPv6
doesn't have the same issue). Last commit improve a hash-related doc.
One example is when using OvS with dp_hash, which uses skb->hash, to
select a path. We'd like packets from the same flow to be consistent, as
well as the hash being stable over time when using net.core.txrehash=0.
Same applies for kernel ECMP which also can use skb->hash.

When using IPv4/TCP, skb->hash comes from sk->sk_txhash except in
TIME_WAIT and SYN_RECV where it's not set in the reply skb from
ip_send_unicast_reply. Those packets will have a mismatched hash with
others from the same flow as their hashes will be 0. IPv6 does not have
the same issue as the hash is set from the socket txhash in those cases.
This commits sets the hash in the reply skb from ip_send_unicast_reply,
which makes the IPv4 code behaving like IPv6.

Some LEDs may require to sleep while doing some operation like setting
brightness and other cleanup.
For this reason, using a spinlock will cause a sleep under spinlock
warning.
It should be safe to convert this to a sleepable lock since:
- sysfs read/write can sleep
- netdev_trig_work is a work queue and can sleep
- netdev _trig_notify can sleep
The spinlock was used when brightness didn't support sleeping, but this
changed and now it supported with brightness_set_blocking().
Convert to mutex lock to permit sleeping using brightness_set_blocking().

Putting NETDEV_LED_MODE_LINKUP in the same list of the netdev trigger
modes is wrong as it's used to set the link state of the device and not
to set a blink mode as it's done by NETDEV_LED_LINK, NETDEV_LED_TX and
NETDEV_LED_RX. It's also wrong to put this state in the same bitmap of the
netdev trigger mode and should be external to it.
Drop NETDEV_LED_MODE_LINKUP from mode list and convert to a simple bool
that will be true or false based on the carrier link. No functional
change intended.

Dev can be renamed also while up for supported device. We currently
wrongly clear the NETDEV_LED_MODE_LINKUP flag on NETDEV_CHANGENAME

Fix this by rechecking if the carrier is ok on NETDEV_CHANGENAME and
correctly set the NETDEV_LED_MODE_LINKUP bit.

syzbot reported [0] a null-ptr-deref in sk_get_rmem0() while using
IPPROTO_UDPLITE (0x88):
14:25:52 executing program 1:
r0 = socket$inet6(0xa, 0x80002, 0x88)
We had a similar report [1] for probably sk_memory_allocated_add()
in __sk_mem_raise_allocated(), and commit c915fe13cbaa ("udplite: fix
NULL pointer dereference") fixed it by setting .memory_allocated for
udplite_prot and udplitev6_prot.
To fix the variant, we need to set either .sysctl_wmem_offset or
.sysctl_rmem.
Now UDP and UDPLITE share the same value for .memory_allocated, so we
use the same .sysctl_wmem_offset for UDP and UDPLITE.

net: phy: mscc: support VSC8501
this updated series of patches adds support for the VSC8501 Ethernet
PHY and fixes support for the VSC8502 PHY in cases where no other
software (like U-Boot) has initialized the PHY after power up.
The first patch simply adds the VSC8502 to the MODULE_DEVICE_TABLE,
where I guess it was unintentionally missing. I have no hardware to
test my change.
The second patch adds the VSC8501 PHY with exactly the same driver
implementation as the existing VSC8502.
The (new) third patch removes phydev locking from
vsc85xx_rgmii_set_skews(), as discussed for v2 of the patch set.
The (now) fourth patch fixes the initialization for VSC8501 and VSC8502.
I have tested this patch with VSC8501 on hardware in RGMII mode only.

Table 4-42 "RGMII CONTROL, ADDRESS 20E2 (0X14)" Bit 11 for each of
them.
By default the RX_CLK is disabled for these PHYs. In cases where no
other software, like U-Boot, enabled the clock, this results in no
received packets being handed to the MAC.
The patch enables this clock output.
According to Microchip support (case number 01268776) this applies
to all modes (RGMII, GMII, and MII).
Other PHYs sharing the same register map and code, like
VSC8530/31/40/41 have the clock enabled and the relevant bit 11 is
reserved and read-only for them. As per previous discussion the
patch still clears the bit on these PHYs, too, possibly more easily
supporting other future PHYs implementing this functionality.
For the VSC8572 family of PHYs, having a different register map,
no such changes are applied.

By default the VSC8501 and VSC8502 RGMII/GMII/MII RX_CLK output is
disabled. To allow packet forwarding towards the MAC it needs to be
enabled.
For other PHYs supported by this driver the clock output is enabled
by default.

Holding the struct phy_device (phydev) lock is unnecessary when
accessing phydev->interface in the PHY driver .config_init method,
which is the only place that vsc85xx_rgmii_set_skews() is called from.
The phy_modify_paged() function implements required MDIO bus level
locking, which can not be achieved by a phydev lock.

Bug fixes for net/handshake
Paolo observed that there is a possible leak of sock->file. I
haven't looked into that yet, but it seems to be separate from
the fixes in this series, so no need to hold these up.
====================
The submissions mentions net-next but it means netdev (perhaps
merge window left over when trees are converged). In any case,
it should have gone into net, but was instead applied to net-next
as commit deb2e484baf9 ("Merge branch 'net-handshake-fixes'").
These are fixes tho, and Chuck needs them to make progress with
the client so double-merging them into net... it is what it is :(

====================
Due to the way the datasec maps like bss, data, rodata are memory
mapped, they cannot be resized with bpf_map__set_value_size() like
non-datasec maps can. This series offers a way to allow the resizing of
datasec maps, by having the mapped regions resized as needed and also
adjusting associated BTF info if possible.
The thought behind this is to allow for use cases where a given datasec
needs to scale to for example the number of CPU's present. A bpf program
can have a global array in a data section with an initial length and
before loading the bpf program, the array length could be extended to
match the CPU count. The selftests included in this series perform this
scaling to an arbitrary value to demonstrate how it can work.

This patch adds test coverage for resizing datasec maps. The first two
subtests resize the bss and custom data sections. In both cases, an
initial array (of length one) has its element set to one. After resizing
the rest of the array is filled with ones as well. A BPF program is then
run to sum the respective arrays and back on the userspace side the sum
is checked to be equal to the number of elements.
The third subtest attempts to perform resizing under conditions that
will result in either the resize failing or the BTF info being cleared.

This patch updates bpf_map__set_value_size() so that if the given map is
memory mapped, it will attempt to resize the mapped region. Initial
contents of the mapped region are preserved. BTF is not required, but
after the mapping is resized an attempt is made to adjust the associated
BTF information if the following criteria is met:
- BTF info is present
- the map is a datasec
- the final variable in the datasec is an array
... the resulting BTF info will be updated so that the final array
variable is associated with a new BTF array type sized to cover the
requested size.
Note that the initial resizing of the memory mapped region can succeed
while the subsequent BTF adjustment can fail. In this case, BTF info is
dropped from the map by clearing the key and value type.

net: pcs: xpcs: cleanups for clause 73 support
This series cleans up xpcs code, moving much of the clause 73 code
out of the driver into places where others can make use of it.
Specifically, we add a helper to convert a clause 73 advertisement
to ethtool link modes to mdio.h, and a helper to resolve the clause
73 negotiation state to phylink, which includes the pause modes.
In doing this cleanup, several issues were identified with the
original xpcs implementation:
1) it masks the link partner advertisement with its own advertisement
so userspace can't see what the full link partner advertisement
was.
2) it was always setting pause modes irrespective of the advertisements
on either end of the link.
3) it was reading the STAT1 registers multiple times. Reading STAT1
has the side effect of unlatching the link-down status, so
multiple reads should be avoided.
This patch series addresses the first two first by addressing the
issues, and then by moving over to the new helpers. The third issue
is solved by restructuring the xpcs code.

lp_advertising is supposed to reflect the link partner's advertisement
unmodified by the local advertisement, but xpcs bitwise ands it with
the local advertisement prior to calculating the resolution of the
negotiation.
Fix this by moving the bitwise and to xpcs_resolve_lpa_c73() so it can
place the results in a temporary bitmap before passing that to
