linux-kselftest-kunit-6.1-rc1
This KUnit update for Linux 6.1-rc1 consists of several documentation
fixes, UML related cleanups, and a feature to enable/disable KUnit
tests. This update includes the following change to
- rename all_test_uml.config, use it for --alltests
Note: if anyone was using all_tests_uml.config, this change breaks them.
This change simplifies the usage and eliminates the need to type:
--kunitconfig=tools/testing/kunit/configs/all_tests_uml.config.
A simple workaround to create a symlink to the new name can solve the
problem for anyone using all_tests_uml.config.
all_tests_uml.config should work across ~all architectures.

Networking changes for 6.1.
Core
----
- Introduce and use a single page frag cache for allocating small skb
heads, clawing back the 10-20% performance regression in UDP flood
test from previous fixes.
- Run packets which already went thru HW coalescing thru SW GRO.
This significantly improves TCP segment coalescing and simplifies
deployments as different workloads benefit from HW or SW GRO.
- Shrink the size of the base zero-copy send structure.
- Move TCP init under a new slow / sleepable version of DO_ONCE().
BPF
---
- Add BPF-specific, any-context-safe memory allocator.
- Add helpers/kfuncs for PKCS#7 signature verification from BPF
programs.
- Define a new map type and related helpers for user space -> kernel
communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF).
- Allow targeting BPF iterators to loop through resources of one
task/thread.
- Add ability to call selected destructive functions.
Expose crash_kexec() to allow BPF to trigger a kernel dump.
Use CAP_SYS_BOOT check on the loading process to judge permissions.
- Enable BPF to collect custom hierarchical cgroup stats efficiently
by integrating with the rstat framework.
- Support struct arguments for trampoline based programs.
Only structs with size <= 16B and x86 are supported.
- Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping
sockets (instead of just TCP and UDP sockets).
- Add a helper for accessing CLOCK_TAI for time sensitive network
related programs.
- Support accessing network tunnel metadata's flags.
- Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open.
- Add support for writing to Netfilter's nf_conn:mark.
Protocols
---------
- WiFi: more Extremely High Throughput (EHT) and Multi-Link
Operation (MLO) work (802.11be, WiFi 7).
- vsock: improve support for SO_RCVLOWAT.
- SMC: support SO_REUSEPORT.
- Netlink: define and document how to use netlink in a "modern" way.
Support reporting missing attributes via extended ACK.
- IPSec: support collect metadata mode for xfrm interfaces.
- TCPv6: send consistent autoflowlabel in SYN_RECV state
and RST packets.
- TCP: introduce optional per-netns connection hash table to allow
better isolation between namespaces (opt-in, at the cost of memory
and cache pressure).
- MPTCP: support TCP_FASTOPEN_CONNECT.
- Add NEXT-C-SID support in Segment Routing (SRv6) End behavior.
- Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets.
- Open vSwitch:
- Allow specifying ifindex of new interfaces.
- Allow conntrack and metering in non-initial user namespace.
- TLS: support the Korean ARIA-GCM crypto algorithm.
- Remove DECnet support.
Driver API
----------
- Allow selecting the conduit interface used by each port
in DSA switches, at runtime.
- Ethernet Power Sourcing Equipment and Power Device support.
- Add tc-taprio support for queueMaxSDU parameter, i.e. setting
per traffic class max frame size for time-based packet schedules.
- Support PHY rate matching - adapting between differing host-side
and link-side speeds.
- Introduce QUSGMII PHY mode and 1000BASE-KX interface mode.
- Validate OF (device tree) nodes for DSA shared ports; make
phylink-related properties mandatory on DSA and CPU ports.
Enforcing more uniformity should allow transitioning to phylink.
- Require that flash component name used during update matches one
of the components for which version is reported by info_get().
- Remove "weight" argument from driver-facing NAPI API as much
as possible. It's one of those magic knobs which seemed like
a good idea at the time but is too indirect to use in practice.
- Support offload of TLS connections with 256 bit keys.

There's not a huge amount of activity in the docs tree this time around,
but a few significant changes even so:
- A complete rewriting of the top-level index.rst file, which mostly
reflects itself in a redone top page in the HTML-rendered docs. The hope
is that the new organization will be a friendlier starting point for
both users and developers.
- Some math-rendering improvements.
- A coding-style.rst update on the use of BUG() and WARN()
- A big maintainer-PHP guide update.
- Some code-of-conduct updates
- More Chinese translation work
Plus the usual pile of typo fixes, corrections, and updates.

kunit: add kunit.enable to enable/disable KUnit test
This patch adds the kunit.enable module parameter that will need to be set to true in addition to KUNIT being enabled for KUnit tests to run. The default value is true giving backwards compatibility. However, for the production+testing use case the new config option KUNIT_DEFAULT_ENABLED can be set to N requiring the tester to opt-in by passing kunit.enable=1 to the kernel.

docs: admin-guide: for kernel bugs refer to other kernel documentation
The current section 'If something goes wrong' makes a number of suggestions
for debugging, bug hunting and reporting issues, which are quite briefly
described in that section.
However, the suggestions are also well covered in other kernel
documentation or sometimes simply outdated. Here, each suggestion in that
section is summarized, and then followed with its assessment, and the
derived action for each suggestion:
- use MAINTAINERS and mailing list: covered in 'Reporting issues',
summarized in the short guide, detailed in its further section.
Reporting issues even provides some specific examples that guides
readers well through the needed steps. Refer to 'Reporting issues'.
- contact Linus Torvalds: probably outdated as currently described.
nevertheless covered in 'Reporting issues'. Reporting issues points out
to contact the relevant kernel maintainers first, and after some
patience and failed attempts with those maintainers, contacting Linus
Torvalds might be okay. Refer to 'Reporting issues'.
- tell what kernel, how to duplicate, the setup, if the problem is new
or old and when did you notice: covered in 'Reporting issues',
especially in Step-by-step guide how to report issues to the kernel
maintainers. Refer to 'Reporting issues'.
- duplicate kernel bug reports exactly: covered in 'Reporting issues',
especially in Write and send the report. Refer to 'Reporting issues'.
- read 'Bug hunting': keep this reference. Refer to 'Bug hunting'.
- compile the kernel with CONFIG_KALLSYMS: covered in 'Reporting issues',
especially in Decode failure messages. Refer to 'Reporting issues'.
- alternatively, use ksymoops: ksymoops at the mentioned URL seems not to
be maintained anymore. It was released roughly once a year until
version 2.4.11 in 2005, but has not seen a new release since then. The
information in ./scripts/ksymoops/README is from 1999, and does not
give more insight on its actual maintenance state either. Ksymoops is
mentioned as system utility in changes.rst, but also not recommended
there. Drop the explanation on using ksymoops.
- alternatively, lookup dump manually with the EIP and nm to determine
the function in which the kernel crashes: this method seems already a
quite advanced and low-level debugging method. Even all the further
references on bug hunting and debugging do not mention it. Drop this
alternative method and limit mentioning methods explained in the other
existing kernel documentation.
- read 'Reporting issues': keep this reference.
Refer to 'Reporting issues'.
- use gdb for debugging: some specific details, e.g., edit
arch/x86/Makefile, are probably outdated or limited to one (historic
important) setup. Using gdb is covered in 'Bug hunting', 'Debugging
kernel and modules via gdb' and 'Using kgdb, kdb and the kernel
debugger internals'. Refer to those three documents.
Overall, it is sufficient to refer to reporting-issues.rst,
bug-hunting.rst, gdb-kernel-debugging.rst and kgdb.rst and this way cover
the existing suggestions.
'Reporting issues' is quite new and probably up to date. 'Bug hunting',
'Debugging kernel and modules via gdb' and 'Using kgdb, kdb and the kernel
debugger internals' might need some revisit and update, but they are
generally in an acceptable state for referring to them.
Replace the existing suggestions by reference to other existing kernel
documentation covering those suggestions---partly even nicely summarized
and then explained in greater detail.

docs: admin-guide: do not mention the 'run a.out user programs' feature
Running a.out user programs with the latest kernel release is a very rare and uncommon use case nowadays. The support of a.out user programs is only remaining for the alpha architecture and is not defined and activated in the architecture's Kconfig (so even the activation of this support requires to modify the Kconfig file and not just kernel build configuration). The discussion on a.out support in 2019 (see Link) shows that the support of a.out user programs is just remaining for a special corner case from some (alpha architecture) users. There is no need to point out and mention this special feature to the general audience of kernel users. Delete the reference to this historic and special feature.

arm64: spectre: increase parameters that can be used to turn off bhb mitigation individually
In our environment, it was found that the mitigation BHB has a great impact on the benchmark performance. For example, in the lmbench test, the "process fork && exit" test performance drops by 20%. So it is necessary to have the ability to turn off the mitigation individually through cmdline, thus avoiding having to compile the kernel by adjusting the config.

x86/apic: Don't disable x2APIC if locked
The APIC supports two modes, legacy APIC (or xAPIC), and Extended APIC (or x2APIC). X2APIC mode is mostly compatible with legacy APIC, but it disables the memory-mapped APIC interface in favor of one that uses MSRs. The APIC mode is controlled by the EXT bit in the APIC MSR. The MMIO/xAPIC interface has some problems, most notably the APIC LEAK [1]. This bug allows an attacker to use the APIC MMIO interface to extract data from the SGX enclave. Introduce support for a new feature that will allow the BIOS to lock the APIC in x2APIC mode. If the APIC is locked in x2APIC mode and the kernel tries to disable the APIC or revert to legacy APIC mode a GP fault will occur. Introduce support for a new MSR (IA32_XAPIC_DISABLE_STATUS) and handle the new locked mode when the LEGACY_XAPIC_DISABLED bit is set by preventing the kernel from trying to disable the x2APIC. On platforms with the IA32_XAPIC_DISABLE_STATUS MSR, if SGX or TDX are enabled the LEGACY_XAPIC_DISABLED will be set by the BIOS. If legacy APIC is required, then it SGX and TDX need to be disabled in the BIOS.

docs: Update version number from 5.x to 6.x in README.rst
A quick 'grep "5\.x" . -R' on Documentation shows that README.rst, 2.Process.rst and applying-patches.rst all mention the version number "5.x" for kernel releases. As the next release will be version 6.0, updating the version number to 6.x in README.rst seems reasonable. The description in 2.Process.rst is just a description of recent kernel releases, it was last updated in the beginning of 2020, and can be revisited at any time on a regular basis, independent of changing the version number from 5 to 6. So, there is no need to update this document now when transitioning from 5.x to 6.x numbering. The document applying-patches.rst is probably obsolete for most users anyway, a reader will sufficiently well understand the steps, even it mentions version 5 rather than version 6. So, do not update that to a version 6.x numbering scheme. Update version number from 5.x to 6.x in README.rst only.

Remove DECnet support from kernel
DECnet is an obsolete network protocol that receives more attention from kernel janitors than users. It belongs in computer protocol history museum not in Linux kernel. It has been "Orphaned" in kernel since 2010. The iproute2 support for DECnet was dropped in 5.0 release. The documentation link on Sourceforge says it is abandoned there as well. Leave the UAPI alone to keep userspace programs compiling. This means that there is still an empty neighbour table for AF_DECNET. The table of /proc/sys/net entries was updated to match current directories and reformatted to be alphabetical.

mm: hugetlb_vmemmap: introduce the name HVO
It it inconvenient to mention the feature of optimizing vmemmap pages associated with HugeTLB pages when communicating with others since there is no specific or abbreviated name for it when it is first introduced. Let us give it a name HVO (HugeTLB Vmemmap Optimization) from now. This commit also updates the document about "hugetlb_free_vmemmap" by the way discussed in thread [1].

Modules updates for 6.0
For the 6.0 merge window the modules code shifts to cleanup and minor fixes
effort. This is becomes much easier to do and review now due to the code
split to its own directory from effort on the last kernel release. I expect
to see more of this with time and as we expand on test coverage in the future.
The cleanups and fixes come from usual suspects such as Christophe Leroy and
Aaron Tomlin but there are also some other contributors.
One particular minor fix worth mentioning is from Helge Deller, where he spotted
a *forever* incorrect natural alignment on both ELF section header tables:
* .altinstructions
* __bug_table sections
A lot of back and forth went on in trying to determine the ill effects of this
misalignment being present for years and it has been determined there should
be no real ill effects unless you have a buggy exception handler. Helge actually
hit one of these buggy exception handlers on parisc which is how he ended up
spotting this issue. When implemented correctly these paths with incorrect
misalignment would just mean a performance penalty, but given that we are
dealing with alternatives on modules and with the __bug_table (where info
regardign BUG()/WARN() file/line information associated with it is stored)
this really shouldn't be a big deal.
The only other change with mentioning is the kmap() with kmap_local_page()
and my only concern with that was on what is done after preemption, but the
virtual addresses are restored after preemption. This is only used on module
decompression.
This all has sit on linux-next for a while except the kmap stuff which has
been there for 3 weeks.

x86/bugs: Enable STIBP for IBPB mitigated RETBleed
AMD's "Technical Guidance for Mitigating Branch Type Confusion,
Rev. 1.0 2022-07-12" whitepaper, under section 6.1.2 "IBPB On
Privileged Mode Entry / SMT Safety" says:
Similar to the Jmp2Ret mitigation, if the code on the sibling thread
cannot be trusted, software should set STIBP to 1 or disable SMT to
ensure SMT safety when using this mitigation.
So, like already being done for retbleed=unret, and now also for
retbleed=ibpb, force STIBP on machines that have it, and report its SMT
vulnerability status accordingly.
[ bp: Remove the "we" and remove "[AMD]" applicability parameter which
doesn't work here. ]

IOMMU Updates for Linux v5.20/v6.0:
Including:
- Most intrusive patch is small and changes the default
allocation policy for DMA addresses. Before the change the
allocator tried its best to find an address in the first 4GB.
But that lead to performance problems when that space gets
exhaused, and since most devices are capable of 64-bit DMA
these days, we changed it to search in the full DMA-mask
range from the beginning. This change has the potential to
uncover bugs elsewhere, in the kernel or the hardware. There
is a Kconfig option and a command line option to restore the
old behavior, but none of them is enabled by default.
- Add Robin Murphy as reviewer of IOMMU code and maintainer for
the dma-iommu and iova code
- Chaning IOVA magazine size from 1032 to 1024 bytes to save
memory
- Some core code cleanups and dead-code removal
- Support for ACPI IORT RMR node
- Support for multiple PCI domains in the AMD-Vi driver
- ARM SMMU changes from Will Deacon:
- Add even more Qualcomm device-tree compatible strings
- Support dumping of IMP DEF Qualcomm registers on TLB sync
timeout
- Fix reference count leak on device tree node in Qualcomm
driver
- Intel VT-d driver updates from Lu Baolu:
- Make intel-iommu.h private
- Optimize the use of two locks
- Extend the driver to support large-scale platforms
- Cleanup some dead code
- MediaTek IOMMU refactoring and support for TTBR up to 35bit
- Basic support for Exynos SysMMU v7
- VirtIO IOMMU driver gets a map/unmap_pages() implementation
- Other smaller cleanups and fixes

Merge tag 'iommu-updates-v5.20-or-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
- The most intrusive patch is small and changes the default allocation
policy for DMA addresses.
Before the change the allocator tried its best to find an address in
the first 4GB. But that lead to performance problems when that space
gets exhaused, and since most devices are capable of 64-bit DMA these
days, we changed it to search in the full DMA-mask range from the
beginning.
This change has the potential to uncover bugs elsewhere, in the
kernel or the hardware. There is a Kconfig option and a command line
option to restore the old behavior, but none of them is enabled by
default.
- Add Robin Murphy as reviewer of IOMMU code and maintainer for the
dma-iommu and iova code
- Chaning IOVA magazine size from 1032 to 1024 bytes to save memory
- Some core code cleanups and dead-code removal
- Support for ACPI IORT RMR node
- Support for multiple PCI domains in the AMD-Vi driver
- ARM SMMU changes from Will Deacon:
- Add even more Qualcomm device-tree compatible strings
- Support dumping of IMP DEF Qualcomm registers on TLB sync
timeout
- Fix reference count leak on device tree node in Qualcomm driver
- Intel VT-d driver updates from Lu Baolu:
- Make intel-iommu.h private
- Optimize the use of two locks
- Extend the driver to support large-scale platforms
- Cleanup some dead code
- MediaTek IOMMU refactoring and support for TTBR up to 35bit
- Basic support for Exynos SysMMU v7
- VirtIO IOMMU driver gets a map/unmap_pages() implementation

Pull MM updates from Andrew Morton:
"Most of the MM queue. A few things are still pending.
Liam's maple tree rework didn't make it. This has resulted in a few
other minor patch series being held over for next time.
Multi-gen LRU still isn't merged as we were waiting for mapletree to
stabilize. The current plan is to merge MGLRU into -mm soon and to
later reintroduce mapletree, with a view to hopefully getting both
into 6.1-rc1.
