Probes updates for v6.9:
- x96/kprobes: Use boolean for some function return instead of 0 and 1.
- x86/kprobes: Prohibit probing on INT/UD. This prevents user to put kprobe on
INTn/INT1/INT3/INTO and UD0/UD1/UD2 because these are used for a special
purpose in the kernel.
- x86/kprobes: Boost Grp instructions. Because a few percent of kernel
instructions are Grp 2/3/4/5 and those are safe to be executed without
ip register fixup, allow those to be boosted (direct execution on the
trampoline buffer with a JMP).
- tracing/probes: Add function argument access from return events (kretprobe
and fprobe). This allows user to compare how a data structure field is
changed after executing a function. With BTF, return event also accepts
function argument access by name. This also includes below patches;
. Fix a wrong comment (using "Kretprobe" in fprobe)
. Cleanup a big probe argument parser function into three parts, type
parser, post-processing function, and main parser.
. Cleanup to set nr_args field when initializing trace_probe instead of
counting up it while parsing.
. Cleanup a redundant #else block from tracefs/README source code.
. Update selftests to check entry argument access from return probes.
. Documentation update about entry argument access from return probes.

The first patch might be a bit controversial, but the second is a rather straightforward fix; more on both below. The first fix from Casey addresses a problem that should have been caught during the ~16 month (?) review cycle, but sadly was not. The good news is that Dmitry caught it very quickly once Linux v6.8 was released. The core issue is the use of size_t parameters to pass buffer sizes back and forth in the syscall; while we could have solved this with a compat syscall definition, given the newness of the syscalls I wanted to attempt to just redefine the size_t parameters as u32 types and avoid the work associated with a set of compat syscalls. However, this is technically a change in the syscall's signature/API so I can understand if you're opposed to this, even if the syscalls are less than a week old. [ Fingers crossed nobody even notices - Linus ] The second fix is a rather trivial fix to allow userspace to call into the lsm_get_self_attr() syscall with a NULL buffer to quickly determine a minimum required size for the buffer. We do have kselftests for this very case, I'm not sure why I didn't notice the failure; I'm going to guess stupidity, tired eyes, I dunno. My apologies we didn't catch this earlier" * tag 'lsm-pr-20240314' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: lsm: handle the NULL buffer case in lsm_fill_user_ctx() lsm: use 32-bit compatible data types in LSM syscalls |

mtd: rawnand: Ensure continuous reads are well disabled
The cont_read.ongoing flag should only be enabled at the beginning of a read operation, and also disabled at its end, so we never end up triggering nasty side effects outside of this scope. The mtd core being highly serialized, we should not be bothered by parallel accesses anyway. In case we reach the end of a read operation and the boolean was not properly disabled, it's a bug, but it's totally manageable. So warn, and then fix the boolean state.

mtd: rawnand: Constrain even more when continuous reads are enabled
As a matter of fact, continuous reads require additional handling at the
operation level in order for them to work properly. The core helpers do
have this additional logic now, but any time a controller implements its
own page helper, this extra logic is "lost". This means we need another
level of per-controller driver checks to ensure they can leverage
continuous reads. This is for now unsupported, so in order to ensure
continuous reads are enabled only when fully using the core page
helpers, we need to add more initial checks.
Also, as performance is not relevant during raw accesses, we also
prevent these from enabling the feature.
This should solve the issue seen with controllers such as the STM32 FMC2
when in sequencer mode. In this case, the continuous read feature would
be enabled but not leveraged, and most importantly not disabled, leading
to further operations to fail.

mtd: rawnand: Ensure all continuous terms are always in sync
While crossing a LUN boundary, it is probably safer (and clearer) to
keep all members of the continuous read structure aligned, including the
pause page (which is the last page of the lun or the last page of the
continuous read). Once these members properly in sync, we can use the
rawnand_cap_cont_reads() helper everywhere to "prepare" the next
continuous read if there is one.

Merge branch 'ignore-additional-fields-in-the-struct_ops-maps-in-an-updated-version'
Kui-Feng Lee says:
====================
Ignore additional fields in the struct_ops maps in an updated version.
According to an offline discussion, it would be beneficial to
implement a backward-compatible method for struct_ops types with
additional fields that are not present in older kernels.
This patchset accepts additional fields of a struct_ops map with all
zero values even if these fields are not in the corresponding type in
the kernel. This provides a way to be backward compatible. User space
programs can use the same map on a machine running an old kernel by
clearing fields that do not exist in the kernel.
For example, in a test case, it adds an additional field "zeroed" that
doesn't exist in struct bpf_testmod_ops of the kernel.
struct bpf_testmod_ops___zeroed {
int (*test_1)(void);
void (*test_2)(int a, int b);
int (*test_maybe_null)(int dummy, struct task_struct *task);
int zeroed;
};
SEC(".struct_ops.link")
struct bpf_testmod_ops___zeroed testmod_zeroed = {
.test_1 = (void *)test_1,
.test_2 = (void *)test_2_v2,
};
Here, it doesn't assign a value to "zeroed" of testmod_zeroed, and by
default the value of this field will be zero. So, the map will be
accepted by libbpf, but libbpf will skip the "zeroed" field. However,
if the "zeroed" field is assigned to any value other than "0", libbpf
will reject to load this map.
---
Changes from v1:
- Fix the issue about function pointer fields.
- Change a warning message, and add an info message for skipping
fields.
- Add a small demo of additional arguments that are not in the
function pointer prototype in the kernel.
v1: https://lore.kernel.org/all/20240312183245.341141-1-thinker.li@gmail.com/
Kui-Feng Lee (3):
libbpf: Skip zeroed or null fields if not found in the kernel type.

selftests/bpf: Ensure libbpf skip all-zeros fields of struct_ops maps.
A new version of a type may have additional fields that do not exist in older versions. Previously, libbpf would reject struct_ops maps with a new version containing extra fields when running on a machine with an old kernel. However, we have updated libbpf to ignore these fields if their values are all zeros or null in order to provide backward compatibility.

libbpf: Prevent null-pointer dereference when prog to load has no BTF
In bpf_objec_load_prog(), there's no guarantee that obj->btf is non-NULL
when passing it to btf__fd(), and this function does not perform any
check before dereferencing its argument (as bpf_object__btf_fd() used to
do). As a consequence, we get segmentation fault errors in bpftool (for
example) when trying to load programs that come without BTF information.
v2: Keep btf__fd() in the fix instead of reverting to bpf_object__btf_fd().

bpftool: Cast pointers for shadow types explicitly.
According to a report, skeletons fail to assign shadow pointers when being compiled with C++ programs. Unlike C doing implicit casting for void pointers, C++ requires an explicit casting. To support C++, we do explicit casting for each shadow pointer. Also add struct_ops_module.skel.h to test_cpp to validate C++ compilation as part of BPF selftests.

drm/xe: Skip VMAs pin when requesting signal to the last XE_EXEC
Doing a XE_EXEC with num_batch_buffer == 0 makes signals passed as argument to be signaled when the last real XE_EXEC is completed. But to do that it was first pinning all VMAs in drm_gpuvm_exec_lock(), this patch remove this pinning as it is not required. This change also help Mesa implementing memory over-commiting recovery as it needs to unbind not needed VMAs when the whole VM can't fit in GPU memory but it can only do the unbiding when the last XE_EXEC is completed. So with this change Mesa can get the signal it want without getting out-of-memory errors. Fixes: |

Now that non-faulting VMs can invalidate VMAs, drop the usm prefix for the tile_invalidated member. v2: - Fix build error (CI) v3: - Don't invalidate VMA if in fault mode, rather kill VM (Thomas) - Update commit message with tile_invalidated name chagne (Thomas) - Wait VM bookkeep slots with VM resv lock (Thomas) v4: - Move list_del_init(&userptr.repin_link) after error check (Thomas) - Assert not in fault mode (Matthew) Fixes: |

bpf: Temporarily disable atomic operations in BPF arena
Currently, the x86 JIT handling PROBE_MEM32 tagged accesses is not
equipped to handle atomic accesses into PTR_TO_ARENA, as no PROBE_MEM32
tagging is performed and no handling is enabled for them.
This will lead to unsafety as the offset into arena will dereferenced
directly without turning it into a base + offset access into the arena
region.
Since the changes to the x86 JIT will be fairly involved, for now,
temporarily disallow use of PTR_TO_ARENA as the destination operand for
atomics until support is added to the JIT backend.

nvme: fix reconnection fail due to reserved tag allocation
We found a issue on production environment while using NVMe over RDMA,
admin_q reconnect failed forever while remote target and network is ok.
After dig into it, we found it may caused by a ABBA deadlock due to tag
allocation. In my case, the tag was hold by a keep alive request
waiting inside admin_q, as we quiesced admin_q while reset ctrl, so the
request maked as idle and will not process before reset success. As
fabric_q shares tagset with admin_q, while reconnect remote target, we
need a tag for connect command, but the only one reserved tag was held
by keep alive command which waiting inside admin_q. As a result, we
failed to reconnect admin_q forever. In order to fix this issue, I
think we should keep two reserved tags for admin queue.

Merge tag 'pci-v6.9-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Consolidate interrupt related code in irq.c (Ilpo Järvinen)
- Reduce kernel size by replacing sysfs resource macros with
functions (Ilpo Järvinen)
- Reduce kernel size by compiling sysfs support only when
CONFIG_SYSFS=y (Lukas Wunner)
- Avoid using Extended Tags on 3ware-9650SE Root Port to work around
an apparent hardware defect (Jörg Wedekind)
Resource management:
- Fix an MMIO mapping leak in pci_iounmap() (Philipp Stanner)
- Move pci_iomap.c and other PCI-specific devres code to drivers/pci
(Philipp Stanner)
- Consolidate PCI devres code in devres.c (Philipp Stanner)
Power management:
- Avoid D3cold on Asus B1400 PCI-NVMe bridge, where firmware doesn't
know how to return correctly to D0, and remove previous quirk that
wasn't as specific (Daniel Drake)
- Allow runtime PM when the driver enables it but doesn't need any
runtime PM callbacks (Raag Jadav)
- Drain runtime-idle callbacks before driver removal to avoid races
between .remove() and .runtime_idle(), which caused intermittent
page faults when the rtsx .runtime_idle() accessed registers that
its .remove() had already unmapped (Rafael J. Wysocki)
Virtualization:
- Avoid Secondary Bus Reset on LSI FW643 so it can be assigned to VMs
with VFIO, e.g., for professional audio software on many Apple
machines, at the cost of leaking state between VMs (Edmund Raile)
Error handling:
- Print all logged TLP Prefixes, not just the first, after AER or DPC
errors (Ilpo Järvinen)
- Quirk the DPC PIO log size for Intel Raptor Lake Root Ports, which
still don't advertise a legal size (Paul Menzel)
- Ignore expected DPC Surprise Down errors on hot removal (Smita
Koralahalli)
- Block runtime suspend while handling AER errors to avoid races that
prevent the device form being resumed from D3hot (Stanislaw
Gruszka)
Peer-to-peer DMA:
- Use atomic XA allocation in RCU read section (Christophe JAILLET)
ASPM:
- Collect bits of ASPM-related code that we need even without
CONFIG_PCIEASPM into aspm.c (David E. Box)
- Save/restore L1 PM Substates config for suspend/resume (David E.
Box)
- Update save_save when ASPM config is changed, so a .slot_reset()
during error recovery restores the changed config, not the
.probe()-time config (Vidya Sagar)
Endpoint framework:
- Refactor and improve pci_epf_alloc_space() API (Niklas Cassel)
- Clean up endpoint BAR descriptions (Niklas Cassel)
- Fix ntb_register_device() name leak in error path (Yang Yingliang)
- Return actual error code for pci_vntb_probe() failure (Yang
Yingliang)
Broadcom STB PCIe controller driver:
- Fix MDIO write polling, which previously never waited for
completion (Jonathan Bell)
Cadence PCIe endpoint driver:
- Clear the ARI "Next Function Number" of last function (Jasko-EXT
Wojciech)
Freescale i.MX6 PCIe controller driver:
- Simplify by replacing switch statements with function pointers for
different hardware variants (Frank Li)
- Simplify by using clk_bulk*() API (Frank Li)
- Remove redundant DT clock and reg/reg-name details (Frank Li)
- Add i.MX95 DT and driver support for both Root Complex and Endpoint
mode (Frank Li)
Microsoft Hyper-V host bridge driver:
- Reduce memory usage by limiting ring buffer size to 16KB instead of
4 pages (Michael Kelley)
Qualcomm PCIe controller driver:
- Add X1E80100 DT and driver support (Abel Vesa)
- Add DT 'required-opps' for SoCs that require a minimum performance
level (Johan Hovold)
- Make DT 'msi-map-mask' optional, depending on how MSI interrupts
are mapped (Johan Hovold)
- Disable ASPM L0s for sc8280xp, sa8540p and sa8295p because the PHY
configuration isn't tuned correctly for L0s (Johan Hovold)
- Split dt-binding qcom,pcie.yaml into qcom,pcie-common.yaml and
separate files for SA8775p, SC7280, SC8180X, SC8280XP, SM8150,
SM8250, SM8350, SM8450, SM8550 for easier reviewing (Krzysztof
Kozlowski)
- Enable BDF to SID translation by disabling bypass mode (Manivannan
Sadhasivam)
- Add endpoint MHI support for Snapdragon SA8775P SoC (Mrinmay
Sarkar)
Synopsys DesignWare PCIe controller driver:
- Allocate 64-bit MSI address if no 32-bit address is available (Ajay
Agarwal)
- Fix endpoint Resizable BAR to actually advertise the required 1MB
size (Niklas Cassel)
MicroSemi Switchtec management driver:
- Release resources if the .probe() fails (Christophe JAILLET)
Miscellaneous:
- Make pcie_port_bus_type const (Ricardo B. Marliere)"

Pin control changes for the v6.9 kernel cycle:
No core changes this time around.
New drivers:
- New driver for Renesas R8A779H0 also known as R-Car V4M.
- New driver for the Awinic AW9523/B I2C GPIO expander.
I found this living out-of-tree in OpenWrt as an upstream
attempt had stalled on the finishing line, so I picked it
up and finished the job.
Improvements:
- The Nomadik pin control driver was for years re-used out of
tree for the ST STA chips, and now the IP was re-used in a
MIPS automotive SoC called MobilEyeq5, so it has been split
in pin control and GPIO drivers so the latter can be reused
by MobilEyeq5. (Along with a long list of cleanups.)
- A lot of overall cleanup and tidying up.
