GCC can see that the value range for "order" is capped, but this leads
it to consider that it might be negative, leading to a false positive

Switch the argument to unsigned int, which removes the compiler needing

Currently disabled EEE modes are shown as supported in ethtool.
Change this by filtering them out when populating data->supported
in genphy_c45_ethtool_get_eee.
Disabled EEE modes are silently filtered out by genphy_c45_write_eee_adv.
This is planned to be removed, therefore ensure in
genphy_c45_ethtool_set_eee that disabled EEE modes are removed from the
user space provided EEE advertisement. For now keep the current behavior
to do this silently.

If pci_alloc_irq_vectors() can't allocate the minimum number of vectors
then it returns -ENOSPC so there is no need to check for that in the
caller. In fact, because pf->msix.min is an unsigned int, it means that
any negative error codes are type promoted to high positive values and
treated as success. So here, the "return -ENOMEM;" is unreachable code.
Check for negatives instead.
Now that we're only dealing with error codes, it's easier to propagate
the error code from pci_alloc_irq_vectors() instead of hardcoding
-ENOMEM.

As all PCS are using the neg_mode parameter rather than the legacy
an_mode, remove the ability to use the legacy an_mode. We remove the
tests in the phylink code, unconditionally passing the PCS neg_mode

Fix issues with enabling SNP host support and effectively SNP support
which is broken with respect to the KVM module being built-in.
SNP host support is enabled in snp_rmptable_init() which is invoked as
device_initcall(). SNP check on IOMMU is done during IOMMU PCI init
(IOMMU_PCI_INIT stage). And for that reason snp_rmptable_init() is
currently invoked via device_initcall() and cannot be invoked via
subsys_initcall() as core IOMMU subsystem gets initialized via
subsys_initcall().
Now, if kvm_amd module is built-in, it gets initialized before SNP host
support is enabled in snp_rmptable_init() :
[ 10.131811] kvm_amd: TSC scaling supported
[ 10.136384] kvm_amd: Nested Virtualization enabled
[ 10.141734] kvm_amd: Nested Paging enabled
[ 10.146304] kvm_amd: LBR virtualization supported
[ 10.151557] kvm_amd: SEV enabled (ASIDs 100 - 509)
[ 10.156905] kvm_amd: SEV-ES enabled (ASIDs 1 - 99)
[ 10.162256] kvm_amd: SEV-SNP enabled (ASIDs 1 - 99)
[ 10.171508] kvm_amd: Virtual VMLOAD VMSAVE supported
[ 10.177052] kvm_amd: Virtual GIF supported
...
...
[ 10.201648] kvm_amd: in svm_enable_virtualization_cpu
And then svm_x86_ops->enable_virtualization_cpu()
(svm_enable_virtualization_cpu) programs MSR_VM_HSAVE_PA as following:
wrmsrl(MSR_VM_HSAVE_PA, sd->save_area_pa);
So VM_HSAVE_PA is non-zero before SNP support is enabled on all CPUs.
snp_rmptable_init() gets invoked after svm_enable_virtualization_cpu()
as following :
...

...
[ 11.264918] SEV-SNP: in snp_rmptable_init

This #GP exception is getting triggered due to the following errata for
AMD family 19h Models 10h-1Fh Processors:
Processor may generate spurious #GP(0) Exception on WRMSR instruction:
Description:
The Processor will generate a spurious #GP(0) Exception on a WRMSR
instruction if the following conditions are all met:
- the target of the WRMSR is a SYSCFG register.
- the write changes the value of SYSCFG.SNPEn from 0 to 1.
- One of the threads that share the physical core has a non-zero
value in the VM_HSAVE_PA MSR.
The document being referred to above:
https://www.amd.com/content/dam/amd/en/documents/processor-tech-docs/revision-guides/57095-PUB_1_01.pdf
To summarize, with kvm_amd module being built-in, KVM/SVM initialization
happens before host SNP is enabled and this SVM initialization
sets VM_HSAVE_PA to non-zero, which then triggers a #GP when
SYSCFG.SNPEn is being set and this will subsequently cause
SNP_INIT(_EX) to fail with INVALID_CONFIG error as SYSCFG[SnpEn] is not
set on all CPUs.
Essentially SNP host enabling code should be invoked before KVM
initialization, which is currently not the case when KVM is built-in.
Add fix to call snp_rmptable_init() early from iommu_snp_enable()
directly and not invoked via device_initcall() which enables SNP host
support before KVM initialization with kvm_amd module built-in.
Add additional handling for `iommu=off` or `amd_iommu=off` options.
Note that IOMMUs need to be enabled for SNP initialization, therefore,
if host SNP support is enabled but late IOMMU initialization fails
then that will cause PSP driver's SNP_INIT to fail as IOMMU SNP sanity
checks in SNP firmware will fail with invalid configuration error as
below:
[ 9.723114] ccp 0000:23:00.1: sev enabled
[ 9.727602] ccp 0000:23:00.1: psp enabled

The kernel's initcall infrastructure lacks the ability to express
dependencies between initcalls, whereas the modules infrastructure
automatically handles dependencies via symbol loading. Ensure the
PSP SEV driver is initialized before proceeding in sev_hardware_setup()
if KVM is built-in as the dependency isn't handled by the initcall
infrastructure.

KVM is dependent on the PSP SEV driver and PSP SEV driver needs to be
loaded before KVM module. In case of module loading any dependent
modules are automatically loaded but in case of built-in modules there
is no inherent mechanism available to specify dependencies between
modules and ensure that any dependent modules are loaded implicitly.
Add a new external API interface for PSP module initialization which
allows PSP SEV driver to be loaded explicitly if KVM is built-in.

There are hooks in the stmmac driver into XPCS to control the EEE
settings when LPI is configured at the MAC. This bypasses the layering.
To allow this to be removed from the stmmac driver, add two new
methods for PCS to inform them when the LPI/EEE enablement state
changes at the MAC.

Small series to make inet_sock_set_state() more interesting for

Current inet_sock_set_state trace from inet_csk_clone_lock() is missing
many details :
... sock:inet_sock_set_state: family=AF_INET6 protocol=IPPROTO_TCP \
sport=4901 dport=0 \
saddr=127.0.0.6 daddr=0.0.0.0 \
saddrv6=:: daddrv6=:: \
oldstate=TCP_LISTEN newstate=TCP_SYN_RECV
Only the sport gives the listener port, no other parts of the n-tuple are correct.
In this patch, I initialize relevant fields of the new socket before
calling inet_sk_set_state(newsk, TCP_SYN_RECV).
We now have a trace including all the source/destination bits.
... sock:inet_sock_set_state: family=AF_INET6 protocol=IPPROTO_TCP \
sport=4901 dport=47648 \
saddr=127.0.0.6 daddr=127.0.0.6 \
saddrv6=2002:a05:6830:1f85:: daddrv6=2001:4860:f803:65::3 \
oldstate=TCP_LISTEN newstate=TCP_SYN_RECV

When using the Qualcomm X55 modem on the ThinkPad X13s, the kernel log is
constantly being filled with errors related to a "sequence number glitch",
e.g.:
[ 1903.284538] sequence number glitch prev=16 curr=0
[ 1913.812205] sequence number glitch prev=50 curr=0
[ 1923.698219] sequence number glitch prev=142 curr=0
[ 2029.248276] sequence number glitch prev=1555 curr=0
[ 2046.333059] sequence number glitch prev=70 curr=0
[ 2076.520067] sequence number glitch prev=272 curr=0
[ 2158.704202] sequence number glitch prev=2655 curr=0
[ 2218.530776] sequence number glitch prev=2349 curr=0
[ 2225.579092] sequence number glitch prev=6 curr=0
Internet connectivity is working fine, so this error seems harmless. It
looks like modem does not preserve the sequence number when entering low
power state; the amount of errors depends on how actively the modem is
being used.
A similar issue has also been seen on USB-based MBIM modems [1]. However,
in cdc_ncm.c the "sequence number glitch" message is a debug message
instead of an error. Apply the same to the mhi_wwan_mbim.c driver to
silence these errors when using the modem.

For GSO packets, skb_cow_head() will reallocate the skb for TSO header
cloned skbs in airoha_dev_xmit(). For this reason, sinfo pointer can be
no more valid. Fix the issue relying on skb_shinfo() macro directly in
airoha_dev_xmit().
The problem exists since
commit 23020f049327 ("net: airoha: Introduce ethernet support for EN7581 SoC")
but it is not a user visible, since we can't currently enable TSO
for DSA user ports since we are missing to initialize net_device
vlan_features field.

net: add EXPORT_IPV6_MOD()
In this series I am adding EXPORT_IPV6_MOD and EXPORT_IPV6_MOD_GPL()
so that we can replace some EXPORT_SYMBOL() when IPV6 is

This is making all the selected symbols internal to core
linux networking.

We have many EXPORT_SYMBOL(x) in networking tree because IPv6
can be built as a module.
CONFIG_IPV6=y is becoming the norm.
Define a EXPORT_IPV6_MOD(x) which only exports x
for modular IPv6.
Same principle applies to EXPORT_IPV6_MOD_GPL()
