Joanne Koong	8357b366cb	bpf: Define no-ops for externally called bpf dynptr functions ... Some bpf dynptr functions will be called from places where if CONFIG_BPF_SYSCALL is not set, then the dynptr function is undefined. For example, when skb type dynptrs are added in the next commit, dynptr functions are called from net/core/filter.c This patch defines no-op implementations of these dynptr functions so that they do not break compilation by being an undefined reference.

Hou Tao	5d5de3a431	bpf: Only allocate one bpf_mem_cache for bpf_cpumask_ma ... The size of bpf_cpumask is fixed, so there is no need to allocate many bpf_mem_caches for bpf_cpumask_ma, just one bpf_mem_cache is enough. Also add comments for bpf_mem_alloc_init() in bpf_mem_alloc.h to prevent future miuse.

Linus Torvalds	5b7c4cabbb	Networking changes for 6.3. ... Core ---- - Add dedicated kmem_cache for typical/small skb->head, avoid having to access struct page at kfree time, and improve memory use. - Introduce sysctl to set default RPS configuration for new netdevs. - Define Netlink protocol specification format which can be used to describe messages used by each family and auto-generate parsers. Add tools for generating kernel data structures and uAPI headers. - Expose all net/core sysctls inside netns. - Remove 4s sleep in netpoll if carrier is instantly detected on boot. - Add configurable limit of MDB entries per port, and port-vlan. - Continue populating drop reasons throughout the stack. - Retire a handful of legacy Qdiscs and classifiers. Protocols --------- - Support IPv4 big TCP (TSO frames larger than 64kB). - Add IP_LOCAL_PORT_RANGE socket option, to control local port range on socket by socket basis. - Track and report in procfs number of MPTCP sockets used. - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path manager. - IPv6: don't check net.ipv6.route.max_size and rely on garbage collection to free memory (similarly to IPv4). - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986). - ICMP: add per-rate limit counters. - Add support for user scanning requests in ieee802154. - Remove static WEP support. - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting. - WiFi 7 EHT channel puncturing support (client & AP). BPF --- - Add a rbtree data structure following the "next-gen data structure" precedent set by recently added linked list, that is, by using kfunc + kptr instead of adding a new BPF map type. - Expose XDP hints via kfuncs with initial support for RX hash and timestamp metadata. - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to better support decap on GRE tunnel devices not operating in collect metadata. - Improve x86 JIT's codegen for PROBE_MEM runtime error checks. - Remove the need for trace_printk_lock for bpf_trace_printk and bpf_trace_vprintk helpers. - Extend libbpf's bpf_tracing.h support for tracing arguments of kprobes/uprobes and syscall as a special case. - Significantly reduce the search time for module symbols by livepatch and BPF. - Enable cpumasks to be used as kptrs, which is useful for tracing programs tracking which tasks end up running on which CPUs in different time intervals. - Add support for BPF trampoline on s390x and riscv64. - Add capability to export the XDP features supported by the NIC. - Add __bpf_kfunc tag for marking kernel functions as kfuncs. - Add cgroup.memory=nobpf kernel parameter option to disable BPF memory accounting for container environments. Netfilter --------- - Remove the CLUSTERIP target. It has been marked as obsolete for years, and we still have WARN splats wrt. races of the out-of-band /proc interface installed by this target. - Add 'destroy' commands to nf_tables. They are identical to the existing 'delete' commands, but do not return an error if the referenced object (set, chain, rule...) did not exist. Driver API ---------- - Improve cpumask_local_spread() locality to help NICs set the right IRQ affinity on AMD platforms. - Separate C22 and C45 MDIO bus transactions more clearly. - Introduce new DCB table to control DSCP rewrite on egress. - Support configuration of Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of shared medium Ethernet. - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing preemption of low priority frames by high priority frames. - Add support for controlling MACSec offload using netlink SET. - Rework devlink instance refcounts to allow registration and de-registration under the instance lock. Split the code into multiple files, drop some of the unnecessarily granular locks and factor out common parts of netlink operation handling. - Add TX frame aggregation parameters (for USB drivers). - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning messages with notifications for debug. - Allow offloading of UDP NEW connections via act_ct. - Add support for per action HW stats in TC. - Support hardware miss to TC action (continue processing in SW from a specific point in the action chain). - Warn if old Wireless Extension user space interface is used with modern cfg80211/mac80211 drivers. Do not support Wireless Extensions for Wi-Fi 7 devices at all. Everyone should switch to using nl80211 interface instead. - Improve the CAN bit timing configuration. Use extack to return error messages directly to user space, update the SJW handling, including the definition of a new default value that will benefit CAN-FD controllers, by increasing their oscillator tolerance.

Dave Hansen	74e19ef0ff	uaccess: Add speculation barrier to copy_from_user() ... The results of "access_ok()" can be mis-speculated. The result is that you can end speculatively: if (access_ok(from, size)) // Right here even for bad from/size combinations. On first glance, it would be ideal to just add a speculation barrier to "access_ok()" so that its results can never be mis-speculated. But there are lots of system calls just doing access_ok() via "copy_to_user()" and friends (example: fstat() and friends). Those are generally not problematic because they do not _consume_ data from userspace other than the pointer. They are also very quick and common system calls that should not be needlessly slowed down. "copy_from_user()" on the other hand uses a user-controller pointer and is frequently followed up with code that might affect caches. Take something like this: if (!copy_from_user(&kernelvar, uptr, size)) do_something_with(kernelvar); If userspace passes in an evil 'uptr' that *actually* points to a kernel addresses, and then do_something_with() has cache (or other) side-effects, it could allow userspace to infer kernel data values. Add a barrier to the common copy_from_user() code to prevent mis-speculated values which happen after the copy. Also add a stub for architectures that do not define barrier_nospec(). This makes the macro usable in generic code. Since the barrier is now usable in generic code, the x86 #ifdef in the BPF code can also go away.

Specifics: - Rework a large bunch of drivers to use the generic thermal trip structure and use the opportunity to do more cleanups by removing unused functions from the OF code (Daniel Lezcano) - Remove core header inclusion from drivers (Daniel Lezcano) - Fix some locking issues related to the generic thermal trip rework (Johan Hovold) - Fix a crash when requesting the critical temperature on tegra, which is related to the generic trip point work (Jon Hunter) - Clean up thermal device unregistration code (Viresh Kumar) - Fix and clean up thermal control core initialization error code paths (Daniel Lezcano) - Relocate the trip points handling code into a separate file (Daniel Lezcano) - Make the thermal core fail registration of thermal zones and cooling devices if the thermal class has not been registered (Rafael Wysocki) - Add trip point initialization helper functions for ACPI-defined trip points and modify two thermal drivers to use them (Rafael Wysocki, Daniel Lezcano) - Make the core thermal control code use sysfs_emit_at() instead of scnprintf() where applicable (ye xingchen) - Consolidate code accessing the Intel TCC (Thermal Control Circuitry) MSRs by introducing library functions for that and making the TCC-related code in thermal drivers use them (Zhang Rui) - Enhance the x86_pkg_temp_thermal driver to support dynamic tjmax changes (Zhang Rui) - Address an "unsigned expression compared with zero" warning in the intel_soc_dts_iosf thermal driver (Yang Li) - Update comments regarding two functions in the Intel Menlow thermal driver (Deming Wang) - Use sysfs_emit_at() instead of scnprintf() in the int340x thermal driver (ye xingchen) - Make the intel_pch thermal driver support the Wellsburg PCH (Tim Zimmermann) - Modify the intel_pch and processor_thermal_device_pci thermal drivers use generic trip point tables instead of thermal zone trip point callbacks (Daniel Lezcano) - Add production mode attribute sysfs attribute to the int340x thermal driver (Srinivas Pandruvada) - Rework dynamic trip point updates handling and locking in the int340x thermal driver (Rafael Wysocki) - Make the int340x thermal driver use a generic trip points table instead of thermal zone trip point callbacks (Rafael Wysocki, Daniel Lezcano) - Clean up and improve the int340x thermal driver (Rafael Wysocki) - Simplify and clean up the intel_pch thermal driver (Rafael Wysocki) - Fix the Intel powerclamp thermal driver and make it use the common idle injection framework (Srinivas Pandruvada) - Add two module parameters, cpumask and max_idle, to the Intel powerclamp thermal driver to allow it to affect only a specific subset of CPUs instead of all of them (Srinivas Pandruvada) - Make the Intel quark_dts thermal driver Use generic trip point objects instead of its own trip point representation (Daniel Lezcano) - Add toctree entry for thermal documents and fix two issues in the Intel powerclamp driver documentation (Bagas Sanjaya) - Use strscpy() to instead of strncpy() in the thermal core (Xu Panda) - Fix thermal_sampling_exit() (Vincent Guittot) - Add Mediatek Low Voltage Thermal Sensor (LVTS) driver (Balsam Chihi) - Add r8a779g0 RCar support to the rcar_gen3 thermal driver (Geert Uytterhoeven) - Fix useless call to set_trips() when resuming in the rcar_gen3 thermal control driver and add interrupt support detection at init time to it (Niklas Söderlund) - Fix memory corruption in the hi3660 thermal driver (Yongqin Liu) - Fix include path for libnl3 in pkg-config file for libthermal (Vibhav Pant) - Remove syscfg-based driver for st as the platform is not supported any more (Alain Volmat)" * tag 'thermal-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (135 commits) thermal/drivers/st: Remove syscfg based driver thermal: Remove core header inclusion from drivers tools/lib/thermal: Fix include path for libnl3 in pkg-config file. thermal/drivers/hisi: Drop second sensor hi3660 thermal/drivers/rcar_gen3_thermal: Fix device initialization thermal/drivers/rcar_gen3_thermal: Create device local ops struct thermal/drivers/rcar_gen3_thermal: Do not call set_trips() when resuming thermal/drivers/rcar_gen3: Add support for R-Car V4H dt-bindings: thermal: rcar-gen3-thermal: Add r8a779g0 support thermal/drivers/mediatek: Add the Low Voltage Thermal Sensor driver dt-bindings: thermal: mediatek: Add LVTS thermal controllers thermal/drivers/mediatek: Relocate driver to mediatek folder tools/lib/thermal: Fix thermal_sampling_exit() Documentation: powerclamp: Fix numbered lists formatting Documentation: powerclamp: Escape wildcard in cpumask description Documentation: admin-guide: Add toctree entry for thermal docs thermal: intel: powerclamp: Add two module parameters Documentation: admin-guide: Move intel_powerclamp documentation thermal: core: Use sysfs_emit_at() instead of scnprintf() thermal: intel: powerclamp: Fix duration module parameter ...	2023-02-21 12:32:05 -08:00

Linus Torvalds	8cc01d43f8	RCU pull request for v6.3 ... This pull request contains the following branches: doc.2023.01.05a: Documentation updates. fixes.2023.01.23a: Miscellaneous fixes, perhaps most notably: o Throttling callback invocation based on the number of callbacks that are now ready to invoke instead of on the total number of callbacks. o Several patches that suppress false-positive boot-time diagnostics, for example, due to lockdep not yet being initialized. o Make expedited RCU CPU stall warnings dump stacks of any tasks that are blocking the stalled grace period. (Normal RCU CPU stall warnings have doen this for mnay years.) o Lazy-callback fixes to avoid delays during boot, suspend, and resume. (Note that lazy callbacks must be explicitly enabled, so this should not (yet) affect production use cases.) kvfree.2023.01.03a: Cause kfree_rcu() and friends to take advantage of polled grace periods, thus reducing memory footprint by almost two orders of magnitude, admittedly on a microbenchmark. This series also begins the transition from kfree_rcu(p) to kfree_rcu_mightsleep(p). This transition was motivated by bugs where kfree_rcu(p), which can block, was typed instead of the intended kfree_rcu(p, rh). srcu.2023.01.03a: SRCU updates, perhaps most notably fixing a bug that causes SRCU to fail when booted on a system with a non-zero boot CPU. This surprising situation actually happens for kdump kernels on the powerpc architecture.

(Normal RCU CPU stall warnings have done this for many years) - Lazy-callback fixes to avoid delays during boot, suspend, and resume. (Note that lazy callbacks must be explicitly enabled, so this should not (yet) affect production use cases) - Make kfree_rcu() and friends take advantage of polled grace periods, thus reducing memory footprint by almost two orders of magnitude, admittedly on a microbenchmark This also begins the transition from kfree_rcu(p) to kfree_rcu_mightsleep(p). This transition was motivated by bugs where kfree_rcu(p), which can block, was typed instead of the intended kfree_rcu(p, rh) - SRCU updates, perhaps most notably fixing a bug that causes SRCU to fail when booted on a system with a non-zero boot CPU.

Paul Blakey	80cd22c35c	net/sched: cls_api: Support hardware miss to tc action ... For drivers to support partial offload of a filter's action list, add support for action miss to specify an action instance to continue from in sw. CT action in particular can't be fully offloaded, as new connections need to be handled in software. This imposes other limitations on the actions that can be offloaded together with the CT action, such as packet modifications. Assign each action on a filter's action list a unique miss_cookie which drivers can then use to fill action_miss part of the tc skb extension. On getting back this miss_cookie, find the action instance with relevant cookie and continue classifying from there.

Kees Cook	f8f185e39b	net/mlx4_en: Introduce flexible array to silence overflow warning ... The call "skb_copy_from_linear_data(skb, inl + 1, spc)" triggers a FORTIFY memcpy() warning on ppc64 platform: In function ‘fortify_memcpy_chk’, inlined from ‘skb_copy_from_linear_data’ at ./include/linux/skbuff.h:4029:2, inlined from ‘build_inline_wqe’ at drivers/net/ethernet/mellanox/mlx4/en_tx.c:722:4, inlined from ‘mlx4_en_xmit’ at drivers/net/ethernet/mellanox/mlx4/en_tx.c:1066:3: ./include/linux/fortify-string.h:513:25: error: call to ‘__write_overflow_field’ declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning] 513 | __write_overflow_field(p_size_field, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Same behaviour on x86 you can get if you use "__always_inline" instead of "inline" for skb_copy_from_linear_data() in skbuff.h The call here copies data into inlined tx destricptor, which has 104 bytes (MAX_INLINE) space for data payload. In this case "spc" is known in compile-time but the destination is used with hidden knowledge (real structure of destination is different from that the compiler can see). That cause the fortify warning because compiler can check bounds, but the real bounds are different. "spc" can't be bigger than 64 bytes (MLX4_INLINE_ALIGN), so the data can always fit into inlined tx descriptor. The fact that "inl" points into inlined tx descriptor is determined earlier in mlx4_en_xmit(). Avoid confusing the compiler with "inl + 1" constructions to get to past the inl header by introducing a flexible array "data" to the struct so that the compiler can see that we are not dealing with an array of inl structs, but rather, arbitrary data following the structure. There are no changes to the structure layout reported by pahole, and the resulting machine code is actually smaller.

Linus Torvalds	950b6662e2	SoC: DT changes for 6.3 ... About a quarter of the changes are for 32-bit arm, mostly filling in device support for existing machines and adding minor cleanups, mostly for Qualcomm and Samsung based machines. Two new 32-bit SoCs are added, both are quad-core Cortex-A7 chips from Rockchips that have been around for a while but were lacking kernel support so far: RV1126 is a Vision SoC with an NPU and is used in the Edgeble Neural Compute Module 2(Neu2) board, while RK3128 is design for TV boxes and so far only comes with a dts for its refernece design. The other 32-bit boards that were added are two ASpeed AST2600 based BMC boards, the Microchip sam9x60_curiosity development board (Armv5 based!), the Enclustra PE1 FPGA-SoM baseboard, and a few more boards for i.MX53 and i.MX6ULL.

Linus Torvalds	ff0c7e1862	ARM: unused boardfile removal for 6.3 ... This is a follow-up to the deprecation of most of the old-style board files that was merged in linux-6.0, removing them for good. This branch is almost exclusively dead code removal based on those annotations. Some device driver removals went through separate subsystem trees, but the majority is in the same branch, in order to better handle dependencies between the patches and avoid breaking bisection. Unfortunately that leads to merge conflicts against other changes in the subsystem trees, but they should all be trivial to resolve by removing the files. See commit 7d0d3fa733 ("Merge tag 'arm-boardfiles-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the description of which machines were marked unused and are now removed.

Linus Torvalds	6639c3ce7f	fsverity updates for 6.3 ... Fix the longstanding implementation limitation that fsverity was only supported when the Merkle tree block size, filesystem block size, and PAGE_SIZE were all equal. Specifically, add support for Merkle tree block sizes less than PAGE_SIZE, and make ext4 support fsverity on filesystems where the filesystem block size is less than PAGE_SIZE. Effectively, this means that fsverity can now be used on systems with non-4K pages, at least on ext4. These changes have been tested using the verity group of xfstests, newly updated to cover the new code paths. Also update fs/verity/ to support verifying data from large folios. There's also a similar patch for fs/crypto/, to support decrypting data from large folios, which I'm including in this pull request to avoid a merge conflict between the fscrypt and fsverity branches.

Decompression is CPU-intensive and it is sleepable for EROFS, so other alternatives like decompression under softirq contexts are not considered. More details are in the corresponding commit message. Others are random cleanups around the whole codebase and we will continue to clean up further in the next few months.

This causes issues in a few scenarios: - Tools like syzkaller cannot figure out that the logged message indicates a bug. - Users that explicitly opt in to have the kernel bug on data corruption by selecting CONFIG_BUG_ON_DATA_CORRUPTION should see the kernel crash when they did actually select that option. - When there are busy inodes after the superblock is shut down later access to such a busy inodes walks through freed memory. It would be better to cleanly crash instead. All of this can be addressed by using the already existing CHECK_DATA_CORRUPTION() macro in these places when kernel bugs are detected.

As promised in last cycle's pull request message this converts everything to rely on struct mnt_idmap. Currently we still pass around the plain namespace that was attached to a mount. This is in general pretty convenient but it makes it easy to conflate namespaces that are relevant on the filesystem with namespaces that are relevant on the mount level. Especially for non-vfs developers without detailed knowledge in this area this was a potential source for bugs. This finishes the conversion. Instead of passing the plain namespace around this updates all places that currently take a pointer to a mnt_userns with a pointer to struct mnt_idmap. Now that the conversion is done all helpers down to the really low-level helpers only accept a struct mnt_idmap argument instead of two namespace arguments. Conflating mount and other idmappings will now cause the compiler to complain loudly thus eliminating the possibility of any bugs. This makes it impossible for filesystem developers to mix up mount and filesystem idmappings as they are two distinct types and require distinct helpers that cannot be used interchangeably. Everything associated with struct mnt_idmap is moved into a single separate file. With that change no code can poke around in struct mnt_idmap. It can only be interacted with through dedicated helpers. That means all filesystems are and all of the vfs is completely oblivious to the actual implementation of idmappings. We are now also able to extend struct mnt_idmap as we see fit. For example, we can decouple it completely from namespaces for users that don't require or don't want to use them at all. We can also extend the concept of idmappings so we can cover filesystem specific requirements. In combination with the vfs{g,u}id_t work we finished in v6.2 this makes this feature substantially more robust and thus difficult to implement wrong by a given filesystem and also protects the vfs. - Enable idmapped mounts for tmpfs and fulfill a longstanding request. A long-standing request from users had been to make it possible to create idmapped mounts for tmpfs. For example, to share the host's tmpfs mount between multiple sandboxes. This is a prerequisite for some advanced Kubernetes cases. Systemd also has a range of use-cases to increase service isolation. And there are more users of this. However, with all of the other work going on this was way down on the priority list but luckily someone other than ourselves picked this up. As usual the patch is tiny as all the infrastructure work had been done multiple kernel releases ago. In addition to all the tests that we already have I requested that Rodrigo add a dedicated tmpfs testsuite for idmapped mounts to xfstests.

With no remaining callers of get_kernel_pages() the function is removed" [ This looks like it's just some random 'tee' cleanup, but the bigger picture impetus for this is really to to to remove historical confusion with mixed use of kernel virtual addresses and 'struct page' pointers. Kernel virtual pointers in the vmalloc space is then particularly confusing - both for looking up a page pointer (when trying to then unify a "virtual address or page" interface) and _particularly_ when mixed with HIGHMEM support and the kmap*() family of remapping. This is particularly true with HIGHMEM getting much less test coverage with 32-bit architectures being increasingly legacy targets. So we actively wanted to remove get_kernel_pages() to make sure nobody else used it too, and thus the 'tee' part is "finally remove last user". See also commit 6647e76ab6 ("v4l2: don't fall back to follow_pfn() if pin_user_pages_fast() fails") for a totally different version of a conceptually similar "let's stop this confusion of different ways of referring to memory". - Linus ] * tag 'remove-get_kernel_pages-for-6.3' of https://git.linaro.org/people/jens.wiklander/linux-tee: mm: Remove get_kernel_pages() tee: Remove call to get_kernel_pages() tee: Remove vmalloc page support highmem: Enhance is_kmap_addr() to check kmap_local_page() mappings	2023-02-20 09:27:39 -08:00
Paolo Abeni	50bcfe8df7	net: make default_rps_mask a per netns attribute ... That really was meant to be a per netns attribute from the beginning. The idea is that once proper isolation is in place in the main namespace, additional demux in the child namespaces will be redundant. Let's make child netns default rps mask empty by default. To avoid bloating the netns with a possibly large cpumask, allocate it on-demand during the first write operation. Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.
