Starting with:
bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY")
the micrel phy driver started respecting phy-mode for the KSZ9031 PHY.
At least with kernel v5.8 configuration provided by this fixup was
overwritten by the micrel driver.
This fixup was providing following configuration:
RX path: 2.58ns delay
rx -0.42 (left shift) + rx_clk +0.96ns (right shift) =
1,38 + 1,2 internal RX delay = 2.58ns
TX path: 0.96ns delay
tx (no delay) + tx_clk 0.96ns (right shift) = 0.96ns
This configuration is outside of the recommended RGMII clock skew delays
and about in the middle of: rgmii-idrx and rgmii-id
Since most embedded systems do not have enough place to introduce
significant clock skew, rgmii-id is the way to go.
In case this patch breaks network functionality on your system, build
kernel with enabled MICREL_PHY. If it is still not working then try
following device tree options:
1. Set (or change) phy-mode in DT to:
phy-mode = "rgmii-id";
This actives internal delay for both RX and TX.
1. Set (or change) phy-mode in DT to:
phy-mode = "rgmii-idrx";
This actives internal delay for RX only.
3. Use following DT properties:
phy-mode = "rgmii";
txen-skew-psec = <0>;
rxdv-skew-psec = <0>;
rxd0-skew-psec = <0>;
rxd1-skew-psec = <0>;
rxd2-skew-psec = <0>;
rxd3-skew-psec = <0>;
rxc-skew-psec = <1860>;
txc-skew-psec = <1860>;
This activates the internal delays for RX and TX, with the value as
the fixup that is removed in this patch.

The section "19) Editor modelines and other cruft" in
Documentation/process/coding-style.rst clearly says, "Do not include any
of these in source files."
I recently receive a patch to explicitly add a new one.
Let's do treewide cleanups, otherwise some people follow the existing code
and attempt to upstream their favoriate editor setups.
It is even nicer if scripts/checkpatch.pl can check it.
If we like to impose coding style in an editor-independent manner, I think
editorconfig (patch [1]) is a saner solution.

In case of a use after free kernel oops, the freeing path of the object
is required to debug futher. In most of cases the object address is
present in one of the registers.
Thus check the register's address and if it belongs to slab, print its
alloc and free path.
e.g. in the below issue register r6 belongs to slab, and a use after
free issue occurred on one of its dereferenced values:

Patch series "drivers/char: remove /dev/kmem for good".
Exploring /dev/kmem and /dev/mem in the context of memory hot(un)plug and
memory ballooning, I started questioning the existence of /dev/kmem.
Comparing it with the /proc/kcore implementation, it does not seem to be
able to deal with things like
a) Pages unmapped from the direct mapping (e.g., to be used by secretmem)
-> kern_addr_valid(). virt_addr_valid() is not sufficient.
b) Special cases like gart aperture memory that is not to be touched
-> mem_pfn_is_ram()
Unless I am missing something, it's at least broken in some cases and might
fault/crash the machine.
Looks like its existence has been questioned before in 2005 and 2010 [1],
after ~11 additional years, it might make sense to revive the discussion.
CONFIG_DEVKMEM is only enabled in a single defconfig (on purpose or by
mistake?). All distributions disable it: in Ubuntu it has been disabled
for more than 10 years, in Debian since 2.6.31, in Fedora at least
starting with FC3, in RHEL starting with RHEL4, in SUSE starting from
15sp2, and OpenSUSE has it disabled as well.
1) /dev/kmem was popular for rootkits [2] before it got disabled
basically everywhere. Ubuntu documents [3] "There is no modern user of
/dev/kmem any more beyond attackers using it to load kernel rootkits.".
RHEL documents in a BZ [5] "it served no practical purpose other than to
serve as a potential security problem or to enable binary module drivers
to access structures/functions they shouldn't be touching"
2) /proc/kcore is a decent interface to have a controlled way to read
kernel memory for debugging puposes. (will need some extensions to
deal with memory offlining/unplug, memory ballooning, and poisoned
pages, though)
3) It might be useful for corner case debugging [1]. KDB/KGDB might be a
better fit, especially, to write random memory; harder to shoot
yourself into the foot.
4) "Kernel Memory Editor" [4] hasn't seen any updates since 2000 and seems
to be incompatible with 64bit [1]. For educational purposes,
/proc/kcore might be used to monitor value updates -- or older
kernels can be used.
5) It's broken on arm64, and therefore, completely disabled there.
Looks like it's essentially unused and has been replaced by better
suited interfaces for individual tasks (/proc/kcore, KDB/KGDB). Let's
just remove it.

The various uses of protect_kernel_linear_mapping_text_rodata() are
not consistent:
- Its definition depends on "64BIT && !XIP_KERNEL",
- Its forward declaration depends on MMU,
- Its single caller depends on "STRICT_KERNEL_RWX && 64BIT && MMU &&
!XIP_KERNEL".
Fix this by settling on the dependencies of the caller, which can be
simplified as STRICT_KERNEL_RWX depends on "MMU && !XIP_KERNEL".
Provide a dummy definition, as the caller is protected by
"IS_ENABLED(CONFIG_STRICT_KERNEL_RWX)" instead of "#ifdef
CONFIG_STRICT_KERNEL_RWX".

When the kernel mapping was moved outside of the linear mapping, the
kernel memory reservation was increased, to take into account mapping
granularity. However, this is done unconditionally, regardless of
whether the kernel memory is mapped read-only or not.
If this extension is not needed, up to 2 MiB may be lost, which has a
big impact on e.g. Canaan K210 (64-bit nommu) platforms with only 8 MiB
of RAM.
Reclaim the lost memory by only extending the reserved region when
needed, i.e. depending on a simplified version of the conditional logic
around the call to protect_kernel_linear_mapping_text_rodata().

On certain AMD platforms, when the IOMMU performance counter source
(csource) field is zero, power-gating for the counter is enabled, which
prevents write access and returns zero for read access.
This can cause invalid perf result especially when event multiplexing
is needed (i.e. more number of events than available counters) since
the current logic keeps track of the previously read counter value,
and subsequently re-program the counter to continue counting the event.
With power-gating enabled, we cannot gurantee successful re-programming
of the counter.
Workaround this issue by :
1. Modifying the ordering of setting/reading counters and enabing/
disabling csources to only access the counter when the csource
is set to non-zero.
2. Since AMD IOMMU PMU does not support interrupt mode, the logic
can be simplified to always start counting with value zero,
and accumulate the counter value when stopping without the need
to keep track and reprogram the counter with the previously read
counter value.
This has been tested on systems with and without power-gating.

As io_threads are fully set up USER threads it's clearer to separate the
code path from the KTHREAD logic.
The only remaining difference to user space threads is that io_threads
never return to user space again. Instead they loop within the given
worker function.
The fact that they never return to user space means they don't have an
user space thread stack. In order to indicate that to tools like gdb we
reset the stack and instruction pointers to 0.
This allows gdb attach to user space processes using io-uring, which like
means that they have io_threads, without printing worrying message like
this:

Defer the call to account guest time until after servicing any IRQ(s)
that happened in the guest or immediately after VM-Exit. Tick-based
accounting of vCPU time relies on PF_VCPU being set when the tick IRQ
handler runs, and IRQs are blocked throughout the main sequence of
vcpu_enter_guest(), including the call into vendor code to actually
enter and exit the guest.
This fixes a bug where reported guest time remains '0', even when
running an infinite loop in the guest:

In VMX, the host NMI handler needs to be invoked after NMI VM-Exit.
Before commit 1a5488ef0dcf6 ("KVM: VMX: Invoke NMI handler via indirect
call instead of INTn"), this was done by INTn ("int $2"). But INTn
microcode is relatively expensive, so the commit reworked NMI VM-Exit
handling to invoke the kernel handler by function call.
But this missed a detail. The NMI entry point for direct invocation is
fetched from the IDT table and called on the kernel stack. But on 64-bit
the NMI entry installed in the IDT expects to be invoked on the IST stack.
It relies on the "NMI executing" variable on the IST stack to work
correctly, which is at a fixed position in the IST stack. When the entry
point is unexpectedly called on the kernel stack, the RSP-addressed "NMI
executing" variable is obviously also on the kernel stack and is
"uninitialized" and can cause the NMI entry code to run in the wrong way.
Provide a non-ist entry point for VMX which shares the C-function with
the regular NMI entry and invoke the new asm entry point instead.
On 32-bit this just maps to the regular NMI entry point as 32-bit has no
ISTs and is not affected.

Drop write_tsc() and write_rdtscp_aux(); the former has no users, and the
latter has only a single user and is slightly misleading since the only
in-kernel consumer of MSR_TSC_AUX is RDPID, not RDTSCP.
No functional change intended.

Initialize MSR_TSC_AUX with CPU node information if RDTSCP or RDPID is
supported. This fixes a bug where vdso_read_cpunode() will read garbage
via RDPID if RDPID is supported but RDTSCP is not. While no known CPU
supports RDPID but not RDTSCP, both Intel's SDM and AMD's APM allow for
RDPID to exist without RDTSCP, e.g. it's technically a legal CPU model
for a virtual machine.
Note, technically MSR_TSC_AUX could be initialized if and only if RDPID
is supported since RDTSCP is currently not used to retrieve the CPU node.
But, the cost of the superfluous WRMSR is negigible, whereas leaving
MSR_TSC_AUX uninitialized is just asking for future breakage if someone
decides to utilize RDTSCP.
Fixes: a582c540ac1b ("x86/vdso: Use RDPID in preference to LSL when available")
