devlink: Allow setting of packet trap group parameters
The previous patch allowed device drivers to publish their default binding between packet trap policers and packet trap groups. However, some users might not be content with this binding and would like to change it. In case user space passed a packet trap policer identifier when setting a packet trap group, invoke the appropriate device driver callback and pass the new policer identifier. v2: * Check for presence of 'DEVLINK_ATTR_TRAP_POLICER_ID' in devlink_trap_group_set() and bail if not present * Add extack error message in case trap group was partially modified Signed-off-by: Ido Schimmel <idosch@mellanox.com> Reviewed-by: Jiri Pirko <jiri@mellanox.com> Acked-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

devlink: Add packet trap group parameters support
Packet trap groups are used to aggregate logically related packet traps. Currently, these groups allow user space to batch operations such as setting the trap action of all member traps. In order to prevent the CPU from being overwhelmed by too many trapped packets, it is desirable to bind a packet trap policer to these groups. For example, to limit all the packets that encountered an exception during routing to 10Kpps. Allow device drivers to bind default packet trap policers to packet trap groups when the latter are registered with devlink. The next patch will enable user space to change this default binding.

devlink: Add packet trap policers support
Devices capable of offloading the kernel's datapath and perform functions such as bridging and routing must also be able to send (trap) specific packets to the kernel (i.e., the CPU) for processing. For example, a device acting as a multicast-aware bridge must be able to trap IGMP membership reports to the kernel for processing by the bridge module. In most cases, the underlying device is capable of handling packet rates that are several orders of magnitude higher compared to those that can be handled by the CPU. Therefore, in order to prevent the underlying device from overwhelming the CPU, devices usually include packet trap policers that are able to police the trapped packets to rates that can be handled by the CPU. This patch allows capable device drivers to register their supported packet trap policers with devlink. User space can then tune the parameters of these policer (currently, rate and burst size) and read from the device the number of packets that were dropped by the policer, if supported. Subsequent patches in the series will allow device drivers to create default binding between these policers and packet trap groups and allow user space to change the binding. v2: * Add 'strict_start_type' in devlink policy * Have device drivers provide max/min rate/burst size for each policer. Use them to check validity of user provided parameters Signed-off-by: Ido Schimmel <idosch@mellanox.com> Reviewed-by: Jiri Pirko <jiri@mellanox.com> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

bpf: Implement bpf_prog replacement for an active bpf_cgroup_link
Add new operation (LINK_UPDATE), which allows to replace active bpf_prog from under given bpf_link. Currently this is only supported for bpf_cgroup_link, but will be extended to other kinds of bpf_links in follow-up patches. For bpf_cgroup_link, implemented functionality matches existing semantics for direct bpf_prog attachment (including BPF_F_REPLACE flag). User can either unconditionally set new bpf_prog regardless of which bpf_prog is currently active under given bpf_link, or, optionally, can specify expected active bpf_prog. If active bpf_prog doesn't match expected one, no changes are performed, old bpf_link stays intact and attached, operation returns a failure. cgroup_bpf_replace() operation is resolving race between auto-detachment and bpf_prog update in the same fashion as it's done for bpf_link detachment, except in this case update has no way of succeeding because of target cgroup marked as dying. So in this case error is returned.

bpf: Implement bpf_link-based cgroup BPF program attachment
Implement new sub-command to attach cgroup BPF programs and return FD-based bpf_link back on success. bpf_link, once attached to cgroup, cannot be replaced, except by owner having its FD. Cgroup bpf_link supports only BPF_F_ALLOW_MULTI semantics. Both link-based and prog-based BPF_F_ALLOW_MULTI attachments can be freely intermixed. To prevent bpf_cgroup_link from keeping cgroup alive past the point when no BPF program can be executed, implement auto-detachment of link. When cgroup_bpf_release() is called, all attached bpf_links are forced to release cgroup refcounts, but they leave bpf_link otherwise active and allocated, as well as still owning underlying bpf_prog. This is because user-space might still have FDs open and active, so bpf_link as a user-referenced object can't be freed yet. Once last active FD is closed, bpf_link will be freed and underlying bpf_prog refcount will be dropped. But cgroup refcount won't be touched, because cgroup is released already. The inherent race between bpf_cgroup_link release (from closing last FD) and cgroup_bpf_release() is resolved by both operations taking cgroup_mutex. So the only additional check required is when bpf_cgroup_link attempts to detach itself from cgroup. At that time we need to check whether there is still cgroup associated with that link. And if not, exit with success, because bpf_cgroup_link was already successfully detached.

Updates for the interrupt subsystem:
Treewide:
- Cleanup of setup_irq() which is not longer required because the
memory allocator is available early. Most cleanup changes come
through the various maintainer trees, so the final removal of
setup_irq() is postponed towards the end of the merge window.
Core:
- Protection against unsafe invocation of interrupt handlers and unsafe
interrupt injection including a fixup of the offending PCI/AER error
injection mechanism.
Invoking interrupt handlers from arbitrary contexts, i.e. outside of
an actual interrupt, can cause inconsistent state on the fragile
x86 interrupt affinity changing hardware trainwreck.
Drivers:
- Second wave of support for the new ARM GICv4.1
- Multi-instance support for Xilinx and PLIC interrupt controllers
- CPU-Hotplug support for PLIC
- The obligatory new driver for X1000 TCU
- Enhancements, cleanups and fixes all over the place

Pull scheduler updates from Ingo Molnar:
"The main changes in this cycle are:
- Various NUMA scheduling updates: harmonize the load-balancer and
NUMA placement logic to not work against each other. The intended
result is better locality, better utilization and fewer migrations.
- Introduce Thermal Pressure tracking and optimizations, to improve
task placement on thermally overloaded systems.
- Implement frequency invariant scheduler accounting on (some) x86
CPUs. This is done by observing and sampling the 'recent' CPU
frequency average at ~tick boundaries. The CPU provides this data
via the APERF/MPERF MSRs. This hopefully makes our capacity
estimates more precise and keeps tasks on the same CPU better even
if it might seem overloaded at a lower momentary frequency. (As
usual, turbo mode is a complication that we resolve by observing
the maximum frequency and renormalizing to it.)
- Add asymmetric CPU capacity wakeup scan to improve capacity
utilization on asymmetric topologies. (big.LITTLE systems)
- PSI fixes and optimizations.
- RT scheduling capacity awareness fixes & improvements.
- Optimize the CONFIG_RT_GROUP_SCHED constraints code.
- Misc fixes, cleanups and optimizations - see the changelog for

NFS: Ensure security label is set for root inode
When using NFSv4.2, the security label for the root inode should be set
via a call to nfs_setsecurity() during the mount process, otherwise the
inode will appear as unlabeled for up to acdirmin seconds. Currently
the label for the root inode is allocated, retrieved, and freed entirely
witin nfs4_proc_get_root().
Add a field for the label to the nfs_fattr struct, and allocate & free
the label in nfs_get_root(), where we also add a call to
nfs_setsecurity(). Note that for the call to nfs_setsecurity() to
succeed, it's necessary to also move the logic calling
security_sb_{set,clone}_security() from nfs_get_tree_common() down into
nfs_get_root()... otherwise the SBLABEL_MNT flag will not be set in the
super_block's security flags and nfs_setsecurity() will silently fail.

Pull EFI updates from Ingo Molnar:
"The EFI changes in this cycle are much larger than usual, for two
(positive) reasons:
- The GRUB project is showing signs of life again, resulting in the
introduction of the generic Linux/UEFI boot protocol, instead of
x86 specific hacks which are increasingly difficult to maintain.
There's hope that all future extensions will now go through that
boot protocol.
- Preparatory work for RISC-V EFI support.
The main changes are:
- Boot time GDT handling changes
- Simplify handling of EFI properties table on arm64
- Generic EFI stub cleanups, to improve command line handling, file
I/O, memory allocation, etc.
- Introduce a generic initrd loading method based on calling back
into the firmware, instead of relying on the x86 EFI handover
protocol or device tree.
- Introduce a mixed mode boot method that does not rely on the x86
EFI handover protocol either, and could potentially be adopted by
other architectures (if another one ever surfaces where one
execution mode is a superset of another)
- Clean up the contents of 'struct efi', and move out everything that
doesn't need to be stored there.
- Incorporate support for UEFI spec v2.8A changes that permit
firmware implementations to return EFI_UNSUPPORTED from UEFI
runtime services at OS runtime, and expose a mask of which ones are
supported or unsupported via a configuration table.
- Partial fix for the lack of by-VA cache maintenance in the
decompressor on 32-bit ARM.
- Changes to load device firmware from EFI boot service memory
regions
- Various documentation updates and minor code cleanups and fixes"

bpf: Verifier, do explicit ALU32 bounds tracking
It is not possible for the current verifier to track ALU32 and JMP ops
correctly. This can result in the verifier aborting with errors even though
the program should be verifiable. BPF codes that hit this can work around
it by changin int variables to 64-bit types, marking variables volatile,
etc. But this is all very ugly so it would be better to avoid these tricks.
But, the main reason to address this now is do_refine_retval_range() was
assuming return values could not be negative. Once we fixed this code that
was previously working will no longer work. See do_refine_retval_range()
patch for details. And we don't want to suddenly cause programs that used
to work to fail.
The simplest example code snippet that illustrates the problem is likely
this,
53: w8 = w0 // r8 <- [0, S32_MAX],
// w8 <- [-S32_MIN, X]
54: w8 <s 0 // r8 <- [0, U32_MAX]
// w8 <- [0, X]
The expected 64-bit and 32-bit bounds after each line are shown on the
right. The current issue is without the w* bounds we are forced to use
the worst case bound of [0, U32_MAX]. To resolve this type of case,
jmp32 creating divergent 32-bit bounds from 64-bit bounds, we add explicit
32-bit register bounds s32_{min|max}_value and u32_{min|max}_value. Then
from branch_taken logic creating new bounds we can track 32-bit bounds
explicitly.
The next case we observed is ALU ops after the jmp32,
53: w8 = w0 // r8 <- [0, S32_MAX],
// w8 <- [-S32_MIN, X]
54: w8 <s 0 // r8 <- [0, U32_MAX]
// w8 <- [0, X]
55: w8 += 1 // r8 <- [0, U32_MAX+1]
// w8 <- [0, X+1]
In order to keep the bounds accurate at this point we also need to track
ALU32 ops. To do this we add explicit ALU32 logic for each of the ALU
ops, mov, add, sub, etc.
Finally there is a question of how and when to merge bounds. The cases
enumerate here,
1. MOV ALU32 - zext 32-bit -> 64-bit
2. MOV ALU64 - copy 64-bit -> 32-bit
3. op ALU32 - zext 32-bit -> 64-bit
4. op ALU64 - n/a
5. jmp ALU32 - 64-bit: var32_off | upper_32_bits(var64_off)
6. jmp ALU64 - 32-bit: (>> (<< var64_off))
Details for each case,
For "MOV ALU32" BPF arch zero extends so we simply copy the bounds
from 32-bit into 64-bit ensuring we truncate var_off and 64-bit
bounds correctly. See zext_32_to_64.
For "MOV ALU64" copy all bounds including 32-bit into new register. If
the src register had 32-bit bounds the dst register will as well.
For "op ALU32" zero extend 32-bit into 64-bit the same as move,
see zext_32_to_64.
For "op ALU64" calculate both 32-bit and 64-bit bounds no merging
is done here. Except we have a special case. When RSH or ARSH is
done we can't simply ignore shifting bits from 64-bit reg into the
32-bit subreg. So currently just push bounds from 64-bit into 32-bit.
This will be correct in the sense that they will represent a valid
state of the register. However we could lose some accuracy if an
ARSH is following a jmp32 operation. We can handle this special
case in a follow up series.
For "jmp ALU32" mark 64-bit reg unknown and recalculate 64-bit bounds
from tnum by setting var_off to ((<<(>>var_off)) | var32_off). We
special case if 64-bit bounds has zero'd upper 32bits at which point
we can simply copy 32-bit bounds into 64-bit register. This catches
a common compiler trick where upper 32-bits are zeroed and then
32-bit ops are used followed by a 64-bit compare or 64-bit op on
a pointer. See __reg_combine_64_into_32().
For "jmp ALU64" cast the bounds of the 64bit to their 32-bit
counterpart. For example s32_min_value = (s32)reg->smin_value. For
tnum use only the lower 32bits via, (>>(<<var_off)). See
__reg_combine_64_into_32().

spi/regulator: Updates for v5.7
At one point in the release cycle I managed to fat finger things and
apply some SPI fixes onto a regulator branch and merge that into the SPI
tree, then pull in a change shared with the MTD tree moving the Mediatek
quadspi driver over to become the Mediatek spi-nor driver in the SPI
tree. This has made a mess which I only just noticed while preparing
this and I can't see a sensible way to unpick things due to other
subsequent merge commits especially the pull from MTD so it looks like
the most sensible thing to do is give up and combine the two pull
requests - I hope this is OK. Sorry about this, I've changed some bits
of workflow which should hopefully help me spot such issues earlier in
future.
Fortunately both subsystems were fairly quiet this cycle, the highlights
are:
regulator:
- Support for Monoloithic Power Systems MP5416, MP8867 and MPS8869 and
Qualcomm PMI8994 and SMB208.
SPI:
- Lots of enhancements for spi-fsl-dspi, including XSPI mode support,
from Vladimir Oltean.
- Support for amlogic Meson G12A, IBM FSI, Mediatek spi-nor (moved from
MTD), NXP i.MX8Mx, Rockchip PX30, RK3308 and RK3328, and Qualcomm
Atheros AR934x/QCA95xx.

Staging/IIO driver patches for 5.7-rc1
Here is the big staging and IIO driver pull request for 5.7-rc1. We again end up deleting more code than we added here, thanks to finally getting rid of the old and obsolete wireless USB stuff, and the exfat code (which is coming in again through the vfs tree in a much cleaner version).

bpf: Don't refcount LISTEN sockets in sk_assign()
Avoid taking a reference on listen sockets by checking the socket type in the sk_assign and in the corresponding skb_steal_sock() code in the the transport layer, and by ensuring that the prefetch free (sock_pfree) function uses the same logic to check whether the socket is refcounted.

net: Track socket refcounts in skb_steal_sock()

bpf: Add socket assign support
Add support for TPROXY via a new bpf helper, bpf_sk_assign(). This helper requires the BPF program to discover the socket via a call to bpf_sk*_lookup_*(), then pass this socket to the new helper. The helper takes its own reference to the socket in addition to any existing reference that may or may not currently be obtained for the duration of BPF processing. For the destination socket to receive the traffic, the traffic must be routed towards that socket via local route. The simplest example route is below, but in practice you may want to route traffic more narrowly (eg by CIDR): $ ip route add local default dev lo This patch avoids trying to introduce an extra bit into the skb->sk, as that would require more invasive changes to all code interacting with the socket to ensure that the bit is handled correctly, such as all error-handling cases along the path from the helper in BPF through to the orphan path in the input. Instead, we opt to use the destructor variable to switch on the prefetch of the socket.

"Here are the io_uring changes for this merge window. Light on new
features this time around (just splice + buffer selection), lots of
cleanups, fixes, and improvements to existing support. In particular,
this contains:
- Cleanup fixed file update handling for stack fallback (Hillf)
- Re-work of how pollable async IO is handled, we no longer require
thread offload to handle that. Instead we rely using poll to drive
this, with task_work execution.
- In conjunction with the above, allow expendable buffer selection,
so that poll+recv (for example) no longer has to be a split
operation.
- Make sure we honor RLIMIT_FSIZE for buffered writes
- Add support for splice (Pavel)
- Linked work inheritance fixes and optimizations (Pavel)

net: phylink: add separate pcs operations structure
Add a separate set of PCS operations, which MAC drivers can use to couple phylink with their associated MAC PCS layer. The PCS operations include: - pcs_get_state() - reads the link up/down, resolved speed, duplex and pause from the PCS. - pcs_config() - configures the PCS for the specified mode, PHY interface type, and setting the advertisement. - pcs_an_restart() - restarts 802.3 in-band negotiation with the link partner - pcs_link_up() - informs the PCS that link has come up, and the parameters of the link. Link parameters are used to program the PCS for fixed speed and non-inband modes.

net: dsa: add port policers
The approach taken to pass the port policer methods on to drivers is pragmatic. It is similar to the port mirroring implementation (in that the DSA core does all of the filter block interaction and only passes simple operations for the driver to implement) and dissimilar to how flow-based policers are going to be implemented (where the driver has full control over the flow_cls_offload data structure).

On low memory system, run time dumps can consume too much memory. Add administrator ability to disable auto dumps per reporter as part of the error flow handle routine. This attribute is not relevant while executing DEVLINK_CMD_HEALTH_REPORTER_DUMP_GET. By default, auto dump is activated for any reporter that has a dump method, as part of the reporter registration to devlink.

devlink: Implicitly set auto recover flag when registering health reporter
When health reporter is registered to devlink, devlink will implicitly set auto recover if and only if the reporter has a recover method. No reason to explicitly get the auto recover flag from the driver. Remove this flag from all drivers that called devlink_health_reporter_create. All existing health reporters set auto recovery to true if they have a recover method. Yet, administrator can unset auto recover via netlink command as prior to this patch.

ptp: Avoid deadlocks in the programmable pin code.
The PTP Hardware Clock (PHC) subsystem offers an API for configuring programmable pins. User space sets or gets the settings using ioctls, and drivers verify dialed settings via a callback. Drivers may also query pin settings by calling the ptp_find_pin() method. Although the core subsystem protects concurrent access to the pin settings, the implementation places illogical restrictions on how drivers may call ptp_find_pin(). When enabling an auxiliary function via the .enable(on=1) callback, drivers may invoke the pin finding method, but when disabling with .enable(on=0) drivers are not permitted to do so. With the exception of the mv88e6xxx, all of the PHC drivers do respect this restriction, but still the locking pattern is both confusing and unnecessary. This patch changes the locking implementation to allow PHC drivers to freely call ptp_find_pin() from their .enable() and .verify() callbacks.
