sched_ext: A second set of fixes for v6.12-rc1
- When sched_ext is in bypass mode (e.g. while disabling the BPF scheduler), it was using one DSQ to implement global FIFO scheduling as all it has to do is guaranteeing reasonable forward progress. On multi-socket machines, this can lead to live-lock conditions under certain workloads. Fixed by splitting the queue used for FIFO scheduling per NUMA node. This required several preparation patches. - Hotplug tests on powerpc could reliably trigger deadlock while enabling a BPF scheduler. This was caused by cpu_hotplug_lock nesting inside scx_fork_rwsem and then CPU hotplug path trying to fork a new thread while holding cpu_hotplug_lock. Fixed by restructuring locking in enable and disable paths so that the two locks are not coupled. This required several preparation patches which also fixed a couple other issues in the enable path. - A build fix for !CONFIG_SMP. - Userspace tooling sync and updates. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCZvsB8A4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGW0cAP9LWESwNvszp0jDglg8kvS6tyHDLNQYLT99Dy4Q NPE1OgD+KUKXuRBOhT3dc9dbwodmPtX2rq36QIgHhoGiPB9hew8= =NH+o -----END PGP SIGNATURE----- Merge tag 'sched_ext-for-6.12-rc1-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext Pull sched_ext fixes from Tejun Heo: - When sched_ext is in bypass mode (e.g. while disabling the BPF scheduler), it was using one DSQ to implement global FIFO scheduling as all it has to do is guaranteeing reasonable forward progress.

x86:
* KVM currently invalidates the entirety of the page tables, not just
those for the memslot being touched, when a memslot is moved or deleted.
The former does not have particularly noticeable overhead, but Intel's
TDX will require the guest to re-accept private pages if they are
dropped from the secure EPT, which is a non starter. Actually,
the only reason why this is not already being done is a bug which
was never fully investigated and caused VM instability with assigned
GeForce GPUs, so allow userspace to opt into the new behavior.
* Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10
functionality that is on the horizon).
* Rework common MSR handling code to suppress errors on userspace accesses to
unsupported-but-advertised MSRs. This will allow removing (almost?) all of
KVM's exemptions for userspace access to MSRs that shouldn't exist based on
the vCPU model (the actual cleanup is non-trivial future work).
* Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC) splits the
64-bit value into the legacy ICR and ICR2 storage, whereas Intel (APICv)
stores the entire 64-bit value at the ICR offset.
* Fix a bug where KVM would fail to exit to userspace if one was triggered by
a fastpath exit handler.
* Add fastpath handling of HLT VM-Exit to expedite re-entering the guest when
there's already a pending wake event at the time of the exit.
* Fix a WARN caused by RSM entering a nested guest from SMM with invalid guest
state, by forcing the vCPU out of guest mode prior to signalling SHUTDOWN
(the SHUTDOWN hits the VM altogether, not the nested guest)
* Overhaul the "unprotect and retry" logic to more precisely identify cases
where retrying is actually helpful, and to harden all retry paths against
putting the guest into an infinite retry loop.
* Add support for yielding, e.g. to honor NEED_RESCHED, when zapping rmaps in
the shadow MMU.
* Refactor pieces of the shadow MMU related to aging SPTEs in prepartion for
adding multi generation LRU support in KVM.
* Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is enabled,
i.e. when the CPU has already flushed the RSB.
* Trace the per-CPU host save area as a VMCB pointer to improve readability
and cleanup the retrieval of the SEV-ES host save area.
* Remove unnecessary accounting of temporary nested VMCB related allocations.
* Set FINAL/PAGE in the page fault error code for EPT violations if and only
if the GVA is valid. If the GVA is NOT valid, there is no guest-side page
table walk and so stuffing paging related metadata is nonsensical.
* Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of
emulating posted interrupt delivery to L2.
* Add a lockdep assertion to detect unsafe accesses of vmcs12 structures.
* Harden eVMCS loading against an impossible NULL pointer deref (really truly
should be impossible).
* Minor SGX fix and a cleanup.
* Misc cleanups
Generic:
* Register KVM's cpuhp and syscore callbacks when enabling virtualization in
hardware, as the sole purpose of said callbacks is to disable and re-enable
virtualization as needed.
* Enable virtualization when KVM is loaded, not right before the first VM
is created. Together with the previous change, this simplifies a
lot the logic of the callbacks, because their very existence implies
virtualization is enabled.
* Fix a bug that results in KVM prematurely exiting to userspace for coalesced
MMIO/PIO in many cases, clean up the related code, and add a testcase.
* Fix a bug in kvm_clear_guest() where it would trigger a buffer overflow _if_
the gpa+len crosses a page boundary, which thankfully is guaranteed to not
happen in the current code base. Add WARNs in more helpers that read/write
guest memory to detect similar bugs.
Selftests:
* Fix a goof that caused some Hyper-V tests to be skipped when run on bare
metal, i.e. NOT in a VM.
* Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES guest.
* Explicitly include one-off assets in .gitignore. Past Sean was completely
wrong about not being able to detect missing .gitignore entries.
* Verify userspace single-stepping works when KVM happens to handle a VM-Exit
in its fastpath.
* Misc cleanups

scx_flatcg: Use a user DSQ for fallback instead of SCX_DSQ_GLOBAL
scx_flatcg was using SCX_DSQ_GLOBAL for fallback handling. However, it is assuming that SCX_DSQ_GLOBAL isn't automatically consumed, which was true a while ago but is no longer the case. Also, there are further changes planned for SCX_DSQ_GLOBAL which will disallow explicit consumption from it. Switch to a user DSQ for fallback.

kselftests: mm: fix wrong __NR_userfaultfd value
grep -rnIF "#define __NR_userfaultfd"
tools/include/uapi/asm-generic/unistd.h:681:#define __NR_userfaultfd 282
arch/x86/include/generated/uapi/asm/unistd_32.h:374:#define
__NR_userfaultfd 374
arch/x86/include/generated/uapi/asm/unistd_64.h:327:#define
__NR_userfaultfd 323
arch/x86/include/generated/uapi/asm/unistd_x32.h:282:#define
__NR_userfaultfd (__X32_SYSCALL_BIT + 323)
arch/arm/include/generated/uapi/asm/unistd-eabi.h:347:#define
__NR_userfaultfd (__NR_SYSCALL_BASE + 388)
arch/arm/include/generated/uapi/asm/unistd-oabi.h:359:#define
__NR_userfaultfd (__NR_SYSCALL_BASE + 388)
include/uapi/asm-generic/unistd.h:681:#define __NR_userfaultfd 282
The number is dependent on the architecture. The above data shows that:
x86 374
x86_64 323
The value of __NR_userfaultfd was changed to 282 when asm-generic/unistd.h
was included. It makes the test to fail every time as the correct number
of this syscall on x86_64 is 323. Fix the header to asm/unistd.h.

tools: fix shared radix-tree build
The shared radix-tree build is not correctly recompiling when
lib/maple_tree.c and lib/test_maple_tree.c are modified - fix this by
adding these core components to the SHARED_DEPS list.
Additionally, add missing header guards to shared header files.

Probes updates for v6.12:
- uprobes: make trace_uprobe->nhit counter a per-CPU one
This makes uprobe event's hit counter per-CPU for improving
scalability on multi-core environment.
- kprobes: Remove obsoleted declaration for init_test_probes
Remove unused init_test_probes() from header.
- Raw tracepoint probe supports raw tracepoint events on modules.
The tracepoint events using fprobe were introduced in v6.5, but
tracepoints can be compiled in modules. This supports such a case.
This includes the following improvements.
. tracepoint: add a function for iterating over all tracepoints in
all modules.
. tracepoint: Add a function for iterating over tracepoints in a
module.
. tracing/fprobe: Support raw tracepoint events on modules.
. tracing/fprobe: Support raw tracepoints on future loaded modules.
This allows user to add tracepoint events on modules which is
not loaded yet.
. selftests/tracing: Add a test for tracepoint events on modules.

The following patchset contains Netfilter fixes for net: Patch #1 and #2 handle an esoteric scenario: Given two tasks sending UDP packets to one another, two packets of the same flow in each direction handled by different CPUs that result in two conntrack objects in NEW state, where reply packet loses race. Then, patch #3 adds a testcase for this scenario. Series from Florian Westphal. 1) NAT engine can falsely detect a port collision if it happens to pick up a reply packet as NEW rather than ESTABLISHED. Add extra code to detect this and suppress port reallocation in this case. 2) To complete the clash resolution in the reply direction, extend conntrack logic to detect clashing conntrack in the reply direction to existing entry. 3) Adds a test case. Then, an assorted list of fixes follow: 4) Add a selftest for tproxy, from Antonio Ojea. 5) Guard ctnetlink_*_size() functions under #if defined(CONFIG_NETFILTER_NETLINK_GLUE_CT) || defined(CONFIG_NF_CONNTRACK_EVENTS) From Andy Shevchenko. 6) Use -m socket --transparent in iptables tproxy documentation. From XIE Zhibang. 7) Call kfree_rcu() when releasing flowtable hooks to address race with netlink dump path, from Phil Sutter. 8) Fix compilation warning in nf_reject with CONFIG_BRIDGE_NETFILTER=n. From Simon Horman. 9) Guard ctnetlink_label_size() under CONFIG_NF_CONNTRACK_EVENTS which is its only user, to address a compilation warning. From Simon Horman. 10) Use rcu-protected list iteration over basechain hooks from netlink dump path. 11) Fix memcg for nf_tables, use GFP_KERNEL_ACCOUNT is not complete. 12) Remove old nfqueue conntrack clash resolution. Instead trying to use same destination address consistently which requires double DNAT, use the existing clash resolution which allows clashing packets go through with different destination. Antonio Ojea originally reported an issue from the postrouting chain, I proposed a fix: https://lore.kernel.org/netfilter-devel/ZuwSwAqKgCB2a51-@calendula/T/ which he reported it did not work for him. 13) Adds a selftest for patch 12. 14) Fixes ipvs.sh selftest. netfilter pull request 24-09-26 * tag 'nf-24-09-26' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: selftests: netfilter: Avoid hanging ipvs.sh kselftest: add test for nfqueue induced conntrack race netfilter: nfnetlink_queue: remove old clash resolution logic netfilter: nf_tables: missing objects with no memcg accounting netfilter: nf_tables: use rcu chain hook list iterator from netlink dump path netfilter: ctnetlink: compile ctnetlink_label_size with CONFIG_NF_CONNTRACK_EVENTS netfilter: nf_reject: Fix build warning when CONFIG_BRIDGE_NETFILTER=n netfilter: nf_tables: Keep deleted flowtable hooks until after RCU docs: tproxy: ignore non-transparent sockets in iptables netfilter: ctnetlink: Guard possible unused functions selftests: netfilter: nft_tproxy.sh: add tcp tests selftests: netfilter: add reverse-clash resolution test case netfilter: conntrack: add clash resolution for reverse collisions netfilter: nf_nat: don't try nat source port reallocation for reverse dir clash ==================== Link: https://patch.msgid.link/20240926110717.102194-1-pablo@netfilter.org Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

kselftest: add test for nfqueue induced conntrack race
The netfilter race happens when two packets with the same tuple are DNATed and enqueued with nfqueue in the postrouting hook. Once one of the packet is reinjected it may be DNATed again to a different destination, but the conntrack entry remains the same and the return packet was dropped. Based on earlier patch from Antonio Ojea.

selftests: netfilter: nft_tproxy.sh: add tcp tests
The TPROXY functionality is widely used, however, there are only mptcp selftests covering this feature. The selftests represent the most common scenarios and can also be used as selfdocumentation of the feature. UDP and TCP testcases are split in different files because of the different nature of the protocols, specially due to the challenges that present to reliable test UDP due to the connectionless nature of the protocol. UDP only covers the scenarios involving the prerouting hook. The UDP tests are signfinicantly slower than the TCP ones, hence they use a larger timeout, it takes 20 seconds to run the full UDP suite on a 48 vCPU Intel(R) Xeon(R) CPU @2.60GHz.

selftests/net: packetdrill: increase timing tolerance in debug mode
Some packetdrill tests are flaky in debug mode. As discussed, increase
tolerance.
We have been doing this for debug builds outside ksft too.
Previous setting was 10000. A manual 50 runs in virtme-ng showed two
failures that needed 12000. To be on the safe side, Increase to 14000.

Rust changes for v6.12
Toolchain and infrastructure:
- Support 'MITIGATION_{RETHUNK,RETPOLINE,SLS}' (which cleans up objtool
warnings), teach objtool about 'noreturn' Rust symbols and mimic
'___ADDRESSABLE()' for 'module_{init,exit}'. With that, we should be
objtool-warning-free, so enable it to run for all Rust object files.
- KASAN (no 'SW_TAGS'), KCFI and shadow call sanitizer support.
- Support 'RUSTC_VERSION', including re-config and re-build on change.
- Split helpers file into several files in a folder, to avoid conflicts
in it. Eventually those files will be moved to the right places with
the new build system. In addition, remove the need to manually export
the symbols defined there, reusing existing machinery for that.
- Relax restriction on configurations with Rust + GCC plugins to just
the RANDSTRUCT plugin.
'kernel' crate:
- New 'list' module: doubly-linked linked list for use with reference
counted values, which is heavily used by the upcoming Rust Binder.
This includes 'ListArc' (a wrapper around 'Arc' that is guaranteed
unique for the given ID), 'AtomicTracker' (tracks whether a 'ListArc'
exists using an atomic), 'ListLinks' (the prev/next pointers for an
item in a linked list), 'List' (the linked list itself), 'Iter' (an
iterator over a 'List'), 'Cursor' (a cursor into a 'List' that allows
to remove elements), 'ListArcField' (a field exclusively owned by a
'ListArc'), as well as support for heterogeneous lists.
- New 'rbtree' module: red-black tree abstractions used by the upcoming
Rust Binder. This includes 'RBTree' (the red-black tree itself),
'RBTreeNode' (a node), 'RBTreeNodeReservation' (a memory reservation
for a node), 'Iter' and 'IterMut' (immutable and mutable iterators),
'Cursor' (bidirectional cursor that allows to remove elements), as
well as an entry API similar to the Rust standard library one.
- 'init' module: add 'write_[pin_]init' methods and the 'InPlaceWrite'
trait. Add the 'assert_pinned!' macro.
- 'sync' module: implement the 'InPlaceInit' trait for 'Arc' by
introducing an associated type in the trait.
- 'alloc' module: add 'drop_contents' method to 'BoxExt'.
- 'types' module: implement the 'ForeignOwnable' trait for
'Pin<Box<T>>' and improve the trait's documentation. In addition,
add the 'into_raw' method to the 'ARef' type.
- 'error' module: in preparation for the upcoming Rust support for
32-bit architectures, like arm, locally allow Clippy lint for those.
Documentation:
- https://rust.docs.kernel.org has been announced, so link to it.
- Enable rustdoc's "jump to definition" feature, making its output a
bit closer to the experience in a cross-referencer.
- Debian Testing now also provides recent Rust releases (outside of
the freeze period), so add it to the list.
MAINTAINERS:
- Trevor is joining as reviewer of the "RUST" entry.
And a few other small bits.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Wait for device readiness after reset by polling Vendor ID and
looking for Configuration RRS instead of polling the Command
register and looking for non-error completions, to avoid hardware
retries done for RRS on non-Vendor ID reads (Bjorn Helgaas)
- Rename CRS Completion Status to RRS ('Request Retry Status') to
match PCIe r6.0 spec usage (Bjorn Helgaas)
- Clear LBMS bit after a manual link retrain so we don't try to
retrain a link when there's no downstream device anymore (Maciej W.
Rozycki)
- Revert to the original link speed after retraining fails instead of
leaving it restricted to 2.5GT/s, so a future device has a chance
to use higher speeds (Maciej W. Rozycki)
- Wait for each level of downstream bus, not just the first, to
become accessible before restoring devices on that bus (Ilpo
Järvinen)
- Add ARCH_PCI_DEV_GROUPS so s390 can add its own attribute_groups
without having to stomp on the core's pdev->dev.groups (Lukas
Wunner)

- Request and map drm/ast BARs with pcim_iomap_region() (Philipp
Stanner)
MSI:
- Add MSI_FLAG_NO_AFFINITY flag for devices that mux MSIs onto a
single IRQ line and cannot set the affinity of each MSI to a
specific CPU core (Marek Vasut)
- Use MSI_FLAG_NO_AFFINITY and remove unnecessary .irq_set_affinity()
implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl,
xilinx-xdma, and xilinx drivers to avoid 'IRQ: set affinity failed'
warnings (Marek Vasut)
Power management:
- Add pwrctl support for ATH11K inside the WCN6855 package (Konrad
Dybcio)
PCI device hotplug:
- Remove unnecessary hpc_ops struct from shpchp (ngn)

control of NVMe RAID storage indicators (ok/fail/locate/
rebuild/etc) (Mariusz Tkaczyk)
- Add support for the ACPI _DSM PCIe SSD status LED management, which
is functionally similar to NPEM but mediated by platform firmware

clocks (Krzysztof Kozlowski)
Altera PCIe controller driver:
- Convert altera DT bindings from text to YAML (Matthew Gerlach)

- Use the 'bridge' reset method if described in the DT (Jim Quinlan)
- Use the 'swinit' reset method if described in the DT (Jim Quinlan)

doesn't imply software control of it (Jim Quinlan)
- Add support for many inbound DMA windows (Jim Quinlan)
- Rename SoC 'type' to 'soc_base' express the fact that SoCs come in
families of multiple similar devices (Jim Quinlan)
- Add Broadcom 7712 DT description and driver support (Jim Quinlan)

statements (Frank Li)
- Manage core reset by using SoC-specific callbacks instead of switch
statements (Frank Li)
- Expand comments for erratum ERR010728 workaround (Frank Li)

sched_ext: Provide a sysfs enable_seq counter
As discussed during the distro-centric session within the sched_ext Microconference at LPC 2024, introduce a sequence counter that is incremented every time a BPF scheduler is loaded. This feature can help distributions in diagnosing potential performance regressions by identifying systems where users are running (or have ran) custom BPF schedulers. Example: arighi@virtme-ng~> cat /sys/kernel/sched_ext/enable_seq 0 arighi@virtme-ng~> sudo scx_simple local=1 global=0 ^CEXIT: unregistered from user space arighi@virtme-ng~> cat /sys/kernel/sched_ext/enable_seq 1 In this way user-space tools (such as Ubuntu's apport and similar) are able to gather and include this information in bug reports.

ring-buffer: Updates for v6.12:
- Merged v6.11-rc3 into trace/ring-buffer/core
The v6.10 ring buffer pull request was not made due to Mathieu Desnoyers
making a comment to the pull request. Mathieu and I resolved it on IRC,
but we did not let Linus know that it was resolved. Linus did not do the
pull thinking it still had some unresolved issues.
The ring buffer work for 6.12 was dependent on both this pull request as
well as the reserve_mem kernel command line option that was going upstream
through the memory management tree. The ring buffer repo was being used by
others so it could not be rebased. In order to continue the work, the
v6.11-rc3 branch was pulled in to get access to the reserve_mem work.
This has the 6.11 pull request that did not make it into 6.11, which was:
tracing/ring-buffer: Have persistent buffer across reboots
This allows for the tracing instance ring buffer to stay persistent across
reboots. The way this is done is by adding to the kernel command line:
trace_instance=boot_map@0x285400000:12M
This will reserve 12 megabytes at the address 0x285400000, and then map
the tracing instance "boot_map" ring buffer to that memory. This will
appear as a normal instance in the tracefs system:
/sys/kernel/tracing/instances/boot_map
A user could enable tracing in that instance, and on reboot or kernel
crash, if the memory is not wiped by the firmware, it will recreate the
trace in that instance. For example, if one was debugging a shutdown of a
kernel reboot:
# cd /sys/kernel/tracing
# echo function > instances/boot_map/current_tracer
# reboot
[..]
# cd /sys/kernel/tracing
# tail instances/boot_map/trace

On reboot, the buffer is examined to make sure it is valid. The validation
check even steps through every event to make sure the meta data of the
event is correct. If any test fails, it will simply reset the buffer, and
the buffer will be empty on boot.
The new changes for 6.12 are:
- Allow the tracing persistent boot buffer to use the "reserve_mem" option
Instead of having the admin find a physical address to store the persistent
buffer, which can be very tedious if they have to administrate several
different machines, allow them to use the "reserve_mem" option that will
find a location for them. It is not as reliable because of KASLR, as the
loading of the kernel in different locations can cause the memory
allocated to be inconsistent. Booting with "nokaslr" can make reserve_mem
more reliable.
- Have function graph tracer handle offsets from a previous boot.
The ring buffer output from a previous boot may have different addresses
due to kaslr. Have the function graph tracer handle these by using the
delta from the previous boot to the new boot address space.
- Only reset the saved meta offset when the buffer is started or reset
In the persistent memory meta data, it holds the previous address space
information, so that it can calculate the delta to have function tracing
work. But this gets updated after being read to hold the new address
space. But if the buffer isn't used for that boot, on reboot, the delta is
now calculated from the previous boot and not the boot that holds the data
in the ring buffer. This causes the functions not to be shown. Do not save
the address space information of the current kernel until it is being
recorded.
- Add a magic variable to test the valid meta data
Add a magic variable in the meta data that can also be used for
validation. The validator of the previous buffer doesn't need this magic
data, but it can be used if the meta data is changed by a new kernel, which
may have the same format that passes the validator but is used
differently. This magic number can also be used as a "versioning" of the
meta data.
- Align user space mapped ring buffer sub buffers to improve TLB entries
Linus mentioned that the mapped ring buffer sub buffers were misaligned
between the meta page and the sub-buffers, so that if the sub-buffers were
bigger than PAGE_SIZE, it wouldn't allow the TLB to use bigger entries.
- Add new kernel command line "traceoff" to disable tracing on boot for instances
If tracing is enabled for a boot instance, there needs a way to be able to
disable it on boot so that new events do not get entered into the ring
buffer and be mixed with events from a previous boot, as that can be
confusing.
- Allow trace_printk() to go to other instances
Currently, trace_printk() can only go to the top level instance. When
debugging with a persistent buffer, it is really useful to be able to add
trace_printk() to go to that buffer, so that you have access to them after
a crash.
- Do not use "bin_printk()" for traces to a boot instance
The bin_printk() saves only a pointer to the printk format in the ring
buffer, as the reader of the buffer can still have access to it. But this
is not the case if the buffer is from a previous boot. If the
trace_printk() is going to a "persistent" buffer, it will use the slower
version that writes the printk format into the buffer.
- Add command line option to allow trace_printk() to go to an instance
Allow the kernel command line to define which instance the trace_printk()
goes to, instead of forcing the admin to set it for every boot via the
tracefs options.
- Start a document that explains how to use tracefs to debug the kernel
- Add some more kernel selftests to test user mapped ring buffer

Pull ring-buffer updates from Steven Rostedt:
- tracing/ring-buffer: persistent buffer across reboots
This allows for the tracing instance ring buffer to stay persistent
across reboots. The way this is done is by adding to the kernel
command line:
trace_instance=boot_map@0x285400000:12M
This will reserve 12 megabytes at the address 0x285400000, and then
map the tracing instance "boot_map" ring buffer to that memory. This
will appear as a normal instance in the tracefs system:
/sys/kernel/tracing/instances/boot_map
A user could enable tracing in that instance, and on reboot or kernel
crash, if the memory is not wiped by the firmware, it will recreate
the trace in that instance. For example, if one was debugging a
shutdown of a kernel reboot:
# cd /sys/kernel/tracing
# echo function > instances/boot_map/current_tracer
# reboot
[..]
# cd /sys/kernel/tracing
# tail instances/boot_map/trace

ktest.pl updates for 6.12:
- Add notification of build warnings for all tests Currently, the build will only fail on warnings if the ktest config file states that it should fail or if the compile is done with -Werror. This has allowed warnings to sneak in if it doesn't fail. Add a notification at the end of the test that will state that warnings were found in the build so that the developer will be aware of it. - Fix the grub2 parser to not return the wrong kernel index ktest.pl can read the grub.cfg file to know what kernel to boot to via grub-reboot. This requires knowing the index that the kernel is referenced by in the grub.cfg file. Some distros have logic to determine the menuentry that can cause the ktest.pl to come up with the wrong index and boot the wrong kernel. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZu+6uBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6quXqAQCfuvT+tQucqGOobqnMjmHf3BEXLwl4 bH5uzWnibT2jLAD+K9JmiY9HYWB7+ozUqRRCJBJFbyH/PH+yI7f2C1KccAM= =turg -----END PGP SIGNATURE----- Merge tag 'ktest-v6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest Pull ktest updates from Steven Rostedt: - Add notification of build warnings for all tests Currently, the build will only fail on warnings if the ktest config file states that it should fail or if the compile is done with '-Werror'.

Merge tag 'bpf-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
Pull bpf updates from Alexei Starovoitov:
- Introduce '__attribute__((bpf_fastcall))' for helpers and kfuncs with
corresponding support in LLVM.
It is similar to existing 'no_caller_saved_registers' attribute in
GCC/LLVM with a provision for backward compatibility. It allows
compilers generate more efficient BPF code assuming the verifier or
JITs will inline or partially inline a helper/kfunc with such
attribute. bpf_cast_to_kern_ctx, bpf_rdonly_cast,
bpf_get_smp_processor_id are the first set of such helpers.
- Harden and extend ELF build ID parsing logic.
When called from sleepable context the relevants parts of ELF file
will be read to find and fetch .note.gnu.build-id information. Also
harden the logic to avoid TOCTOU, overflow, out-of-bounds problems.
- Improvements and fixes for sched-ext:
- Allow passing BPF iterators as kfunc arguments
- Make the pointer returned from iter_next method trusted
- Fix x86 JIT convergence issue due to growing/shrinking conditional
jumps in variable length encoding
- BPF_LSM related:
- Introduce few VFS kfuncs and consolidate them in
fs/bpf_fs_kfuncs.c
- Enforce correct range of return values from certain LSM hooks
- Disallow attaching to other LSM hooks
- Prerequisite work for upcoming Qdisc in BPF:
- Allow kptrs in program provided structs
- Support for gen_epilogue in verifier_ops
- Important fixes:
- Fix uprobe multi pid filter check
- Fix bpf_strtol and bpf_strtoul helpers
- Track equal scalars history on per-instruction level
- Fix tailcall hierarchy on x86 and arm64
- Fix signed division overflow to prevent INT_MIN/-1 trap on x86
- Fix get kernel stack in BPF progs attached to tracepoint:syscall
- Selftests:
- Add uprobe bench/stress tool
- Generate file dependencies to drastically improve re-build time
- Match JIT-ed and BPF asm with __xlated/__jited keywords
- Convert older tests to test_progs framework
- Add support for RISC-V
- Few fixes when BPF programs are compiled with GCC-BPF backend
(support for GCC-BPF in BPF CI is ongoing in parallel)
- Add traffic monitor
- Enable cross compile and musl libc

xdrgen: Prevent reordering of encoder and decoder functions
I noticed that "xdrgen source" reorders the procedure encoder and decoder functions every time it is run. I would prefer that the generated code be more deterministic: it enables a reader to better see exactly what has changed between runs of the tool. The problem is that Python sets are not ordered. I use a Python set to ensure that, when multiple procedures use a particular argument or result type, the encoder/decoder for that type is emitted only once. Sets aren't ordered, but I can use Python dictionaries for this purpose to ensure the procedure functions are always emitted in the same order if the .x file does not change.

xdrgen: Fix return code checking in built-in XDR decoders
xdr_stream_encode_u32() returns XDR_UNIT on success. xdr_stream_decode_u32() returns zero or -EMSGSIZE, but never XDR_UNIT. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> |

tools: Add xdrgen
Add a Python-based tool for translating XDR specifications into XDR encoder and decoder functions written in the Linux kernel's C coding style. The generator attempts to match the usual C coding style of the Linux kernel's SunRPC consumers. This approach is similar to the netlink code generator in tools/net/ynl . The maintainability benefits of machine-generated XDR code include: - Stronger type checking - Reduces the number of bugs introduced by human error - Makes the XDR code easier to audit and analyze - Enables rapid prototyping of new RPC-based protocols - Hardens the layering between protocol logic and marshaling - Makes it easier to add observability on demand - Unit tests might be built for both the tool and (automatically) for the generated code In addition, converting the XDR layer to use memory-safe languages such as Rust will be easier if much of the code can be converted automatically.
