2024-01-12scripts/decode_stacktrace.sh: optionally use LLVM utilitiesCarlos Llamas1-2/+17
GNU's addr2line can have problems parsing a vmlinux built with LLVM, particularly when LTO was used. In order to decode the traces correctly this patch adds the ability to switch to LLVM's utilities readelf and addr2line. The same approach is followed by Will in [1]. Before: $ scripts/decode_stacktrace.sh vmlinux < kernel.log [17716.240635] Call trace: [17716.240646] skb_cow_data (??:?) [17716.240654] esp6_input (ld-temp.o:?) [17716.240666] xfrm_input (ld-temp.o:?) [17716.240674] xfrm6_rcv (??:?) [...] After: $ LLVM=1 scripts/decode_stacktrace.sh vmlinux < kernel.log [17716.240635] Call trace: [17716.240646] skb_cow_data (include/linux/skbuff.h:2172 net/core/skbuff.c:4503) [17716.240654] esp6_input (net/ipv6/esp6.c:977) [17716.240666] xfrm_input (net/xfrm/xfrm_input.c:659) [17716.240674] xfrm6_rcv (net/ipv6/xfrm6_input.c:172) [...] Note that one could set CROSS_COMPILE=llvm- instead to hack around this issue. However, doing so can break the decodecode routine as it will force the selection of other LLVM utilities down the line e.g. llvm-as.

Pull documentation update from Jonathan Corbet: "Another moderately busy cycle for documentation, including: - The minimum Sphinx requirement has been raised to 2.4.4, following a warning that was added in 6.2 - Some reworking of the Documentation/process front page to, hopefully, make it more useful - Various kernel-doc tweaks to, for example, make it deal properly with __counted_by annotations - We have also restored a warning for documentation of nonexistent structure members that disappeared a while back. That had the delightful consequence of adding some 600 warnings to the docs build. A sustained effort by Randy, Vegard, and myself has addressed almost all of those, bringing the documentation back into sync with the code. The fixes are going through the appropriate maintainer trees - Various improvements to the HTML rendered docs, including automatic links to Git revisions and a nice new pulldown to make translations easy to access - Speaking of translations, more of those for Spanish and Chinese ... plus the usual stream of documentation updates and typo fixes" * tag 'docs-6.8' of git://git.lwn.net/linux: (57 commits) MAINTAINERS: use tabs for indent of CONFIDENTIAL COMPUTING THREAT MODEL A reworked process/index.rst ring-buffer/Documentation: Add documentation on buffer_percent file Translated the RISC-V architecture boot documentation.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "The most interesting thing is probably the networking structs reorganization and a significant amount of changes is around self-tests. Core & protocols: - Analyze and reorganize core networking structs (socks, netdev, netns, mibs) to optimize cacheline consumption and set up build time warnings to safeguard against future header changes This improves TCP performances with many concurrent connections up to 40% - Add page-pool netlink-based introspection, exposing the memory usage and recycling stats. This helps indentify bad PP users and possible leaks - Refine TCP/DCCP source port selection to no longer favor even source port at connect() time when IP_LOCAL_PORT_RANGE is set. This lowers the time taken by connect() for hosts having many active connections to the same destination - Refactor the TCP bind conflict code, shrinking related socket structs - Refactor TCP SYN-Cookie handling, as a preparation step to allow arbitrary SYN-Cookie processing via eBPF - Tune optmem_max for 0-copy usage, increasing the default value to 128KB and namespecifying it - Allow coalescing for cloned skbs coming from page pools, improving RX performances with some common configurations - Reduce extension header parsing overhead at GRO time - Add bridge MDB bulk deletion support, allowing user-space to request the deletion of matching entries - Reorder nftables struct members, to keep data accessed by the datapath first - Introduce TC block ports tracking and use. This allows supporting multicast-like behavior at the TC layer - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and classifiers (RSVP and tcindex) - More data-race annotations - Extend the diag interface to dump TCP bound-only sockets - Conditional notification of events for TC qdisc class and actions - Support for WPAN dynamic associations with nearby devices, to form a sub-network using a specific PAN ID - Implement SMCv2.1 virtual ISM device support - Add support for Batman-avd mulicast packet type BPF: - Tons of verifier improvements: - BPF register bounds logic and range support along with a large test suite - log improvements - complete precision tracking support for register spills - track aligned STACK_ZERO cases as imprecise spilled registers. This improves the verifier "instructions processed" metric from single digit to 50-60% for some programs - support for user's global BPF subprogram arguments with few commonly requested annotations for a better developer experience - support tracking of BPF_JNE which helps cases when the compiler transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the like - several fixes - Add initial TX metadata implementation for AF_XDP with support in mlx5 and stmmac drivers. Two types of offloads are supported right now, that is, TX timestamp and TX checksum offload - Fix kCFI bugs in BPF all forms of indirect calls from BPF into kernel and from kernel into BPF work with CFI enabled. This allows BPF to work with CONFIG_FINEIBT=y - Change BPF verifier logic to validate global subprograms lazily instead of unconditionally before the main program, so they can be guarded using BPF CO-RE techniques - Support uid/gid options when mounting bpffs - Add a new kfunc which acquires the associated cgroup of a task within a specific cgroup v1 hierarchy where the latter is identified by its id - Extend verifier to allow bpf_refcount_acquire() of a map value field obtained via direct load which is a use-case needed in sched_ext - Add BPF link_info support for uprobe multi link along with bpftool integration for the latter - Support for VLAN tag in XDP hints - Remove deprecated bpfilter kernel leftovers given the project is developed in user-space (https://github.com/facebook/bpfilter) Misc: - Support for parellel TC self-tests execution - Increase MPTCP self-tests coverage - Updated the bridge documentation, including several so-far undocumented features - Convert all the net self-tests to run in unique netns, to avoid random failures due to conflict and allow concurrent runs - Add TCP-AO self-tests - Add kunit tests for both cfg80211 and mac80211 - Autogenerate Netlink families documentation from YAML spec - Add yml-gen support for fixed headers and recursive nests, the tool can now generate user-space code for all genetlink families for which we have specs - A bunch of additional module descriptions fixes - Catch incorrect freeing of pages belonging to a page pool Driver API: - Rust abstractions for network PHY drivers; do not cover yet the full C API, but already allow implementing functional PHY drivers in rust - Introduce queue and NAPI support in the netdev Netlink interface, allowing complete access to the device <> NAPIs <> queues relationship - Introduce notifications filtering for devlink to allow control application scale to thousands of instances - Improve PHY validation, requesting rate matching information for each ethtool link mode supported by both the PHY and host - Add support for ethtool symmetric-xor RSS hash - ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD platform - Expose pin fractional frequency offset value over new DPLL generic netlink attribute - Convert older drivers to platform remove callback returning void - Add support for PHY package MMD read/write New hardware / drivers: - Ethernet: - Octeon CN10K devices - Broadcom 5760X P7 - Qualcomm SM8550 SoC - Texas Instrument DP83TG720S PHY - Bluetooth: - IMC Networks Bluetooth radio Removed: - WiFi: - libertas 16-bit PCMCIA support - Atmel at76c50x drivers - HostAP ISA/PCMCIA style 802.11b driver - zd1201 802.11b USB dongles - Orinoco ISA/PCMCIA 802.11b driver - Aviator/Raytheon driver - Planet WL3501 driver - RNDIS USB 802.11b driver Driver updates: - Ethernet high-speed NICs: - Intel (100G, ice, idpf): - allow one by one port representors creation and removal - add temperature and clock information reporting - add get/set for ethtool's header split ringparam - add again FW logging - adds support switchdev hardware packet mirroring - iavf: implement symmetric-xor RSS hash - igc: add support for concurrent physical and free-running timers - i40e: increase the allowable descriptors - nVidia/Mellanox: - Preparation for Socket-Direct multi-dev netdev.

This series notably contains a patch from Jiaxun Yang that converts MIPS to use asm-generic/io.h like every other architecture does, enabling future cleanups. Some of my own patches fix -Wmissing-prototype warnings in architecture specific code across several architectures. This is now needed as the warning is enabled by default. There are still some remaining warnings in minor platforms, but the series should catch most of the widely used ones make them more consistent with one another.

Example: the file Documenation/ABI/testing/sysfs-bus-papr-pmem.orig causes this warning message: Documentation/ABI/testing/sysfs-bus-papr-pmem:2: WARNING: unknown document: '/powerpc/papr_hcalls' Prevent this by skipping over filenames that may be created by patch/diff tools etc. Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Jonathan Corbet <corbet@lwn.net> Cc: linux-doc@vger.kernel.org Acked-by: Mauro Carvalho Chehab <mchehab@kernel.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net> Link: https://lore.kernel.org/r/20231228233113.5218-1-rdunlap@infradead.org
2024-01-03scripts/get_abi: fix source path leakVegard Nossum1-1/+1
The code currently leaks the absolute path of the ABI files into the rendered documentation. There exists code to prevent this, but it is not effective when an absolute path is passed, which it is when $srctree is used. I consider this to be a minimal, stop-gap fix; a better fix would strip off the actual prefix instead of hacking it off with a regex.

2023-12-31get_maintainer: remove stray punctuation when cleaning file emailsAlvin Šipraga1-7/+11
When parsing emails from .yaml files in particular, stray punctuation such as a leading '-' can end up in the name. For example, consider a common YAML section such as: maintainers: - devicetree@vger.kernel.org This would previously be processed by get_maintainer.pl as: - <devicetree@vger.kernel.org> Make the logic in clean_file_emails more robust by deleting any sub-names which consist of common single punctuation marks before proceeding to the best-effort name extraction logic. The output is then correct: devicetree@vger.kernel.org Some additional comments are added to the function to make things clearer to future readers.

2023-12-31get_maintainer: correctly parse UTF-8 encoded names in filesAlvin Šipraga1-13/+17
While the script correctly extracts UTF-8 encoded names from the MAINTAINERS file, the regular expressions damage my name when parsing from .yaml files. Fix this by replacing the Latin-1-compatible regular expressions with the unicode property matcher \p{L}, which matches on any letter according to the Unicode General Category of letters. The proposed solution only works if the script uses proper string encoding from the outset, so instruct Perl to unconditionally open all files with UTF-8 encoding. This should be safe, as the entire source tree is either UTF-8 or ASCII encoded anyway. See [1] for a detailed analysis. Furthermore, to prevent the \w expression from matching non-ASCII when checking for whether a name should be escaped with quotes, add the /a flag to the regular expression. The escaping logic was duplicated in two places, so it has been factored out into its own function. The original issue was also identified on the tools mailing list [2]. This should solve the observed side effects there as well.

2023-12-29scripts/decode_stacktrace.sh: strip unexpected CR from linesBjorn Andersson1-0/+3
When the kernel log is acquired over a serial cable it is not uncommon for the log to contain carriage return characters, in addition to the expected line feeds. When this output is feed into decode_stacktrace.sh, handle_line() fails to strip the trailing ']' off the module name, which results in find_module() not being able to find the referred to kernel module. This is reported to the user as: WARNING! Modules path isn't set, but is needed to parse this symbol The solution is to reconfigure the serial port, or to strip the carriage returns from the log, but this isn't obvious from the error reported by the script. Instead, make decode_stacktrace.sh more user friendly by stripping the trailing carriage return.

According to Documentation/process/submit-checklist.rst, checkstack does not point out problems explicitly, but any one function that uses more than 512 bytes on the stack is a candidate for change, hence it is better to omit any stack frame sizes smaller than 512 bytes, just change min_stack to 512 by default.

2023-12-29scripts/checkstack.pl: match all stack sizes for some archsTiezhu Yang1-6/+6
For some unknown reason the regular expression for checkstack only matches three digit numbers starting with the number "3", or any higher number. Which means that it skips any stack sizes smaller than 304 bytes. This makes the checkstack script a bit less useful than it could be. Change the script to match any number. To be filtered out stack sizes can be configured with the min_stack variable, which omits any stack frame sizes smaller than 100 bytes by default. This is similar with commit aab1f809d754 ("scripts/checkstack.pl: match all stack sizes for s390").

When a path contains relative symbolic links, os.path.abspath() might not follow the symlinks and instead return the absolute path with just the relative paths resolved, resulting in an incorrect path. 1.

Makefile drwxrwxr-x 3 ... 4096 ... wifi 2. One .cmd file records that: # head -1 ./framework/core/manager/src/.devmgr_service.o.cmd cmd_drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.o := ... \ /path/to/src/drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.c 3. os.path.abspath returns "/path/to/src/framework/core/manager/src/devmgr_service.c", not correct: # ./scripts/clang-tools/gen_compile_commands.py INFO: Could not add line from ./framework/core/manager/src/.devmgr_service.o.cmd: File \ /path/to/src/framework/core/manager/src/devmgr_service.c not found Use os.path.realpath(), which resolves the symlinks and normalizes the paths correctly. # cat compile_commands.json ... { "command": ...

2023-12-21rust: upgrade to Rust 1.74.1Miguel Ojeda1-1/+1
This is the next upgrade to the Rust toolchain, from 1.73.0 to 1.74.1 (i.e. the latest) [1]. See the upgrade policy [2] and the comments on the first upgrade in commit 3ed03f4da06e ("rust: upgrade to Rust 1.68.2"). # Unstable features No unstable features (that we use) were stabilized. Therefore, the only unstable features allowed to be used outside the `kernel` crate are still `new_uninit,offset_of`, though other code to be upstreamed may increase the list (e.g. `offset_of` was added recently). Please see [3] for details. # Other improvements Rust 1.74.0 allows to use `#[repr(Rust)]` explicitly [4], which can be useful to be explicit about particular cases that would normally use e.g. the C representation, such as silencing lints like the upcoming additions we requested [5] to the `no_mangle_with_rust_abi` Clippy lint (which in turn triggered the `#[repr(Rust)]` addition). Rust 1.74.0 includes a fix for one of the false negative cases we reported in Clippy's `disallowed_macros` lint [6] that we would like to use in the future. Rust 1.74.1 fixes an ICE that the Apple AGX GPU driver was hitting [7]. # Required changes For this upgrade, no changes were required (i.e. on our side). # `alloc` upgrade and reviewing The vast majority of changes are due to our `alloc` fork being upgraded at once. There are two kinds of changes to be aware of: the ones coming from upstream, which we should follow as closely as possible, and the updates needed in our added fallible APIs to keep them matching the newer infallible APIs coming from upstream. Instead of taking a look at the diff of this patch, an alternative approach is reviewing a diff of the changes between upstream `alloc` and the kernel's. This allows to easily inspect the kernel additions only, especially to check if the fallible methods we already have still match the infallible ones in the new version coming from upstream. Another approach is reviewing the changes introduced in the additions in the kernel fork between the two versions. This is useful to spot potentially unintended changes to our additions. To apply these approaches, one may follow steps similar to the following to generate a pair of patches that show the differences between upstream Rust and the kernel (for the subset of `alloc` we use) before and after applying this patch: # Get the difference with respect to the old version. git -C rust checkout $(linux/scripts/min-tool-version.sh rustc) git -C linux ls-tree -r --name-only HEAD -- rust/alloc | cut -d/ -f3- | grep -Fv README.md | xargs -IPATH cp rust/library/alloc/src/PATH linux/rust/alloc/PATH git -C linux diff --patch-with-stat --summary -R > old.patch git -C linux restore rust/alloc # Apply this patch. git -C linux am rust-upgrade.patch # Get the difference with respect to the new version. git -C rust checkout $(linux/scripts/min-tool-version.sh rustc) git -C linux ls-tree -r --name-only HEAD -- rust/alloc | cut -d/ -f3- | grep -Fv README.md | xargs -IPATH cp rust/library/alloc/src/PATH linux/rust/alloc/PATH git -C linux diff --patch-with-stat --summary -R > new.patch git -C linux restore rust/alloc Now one may check the `new.patch` to take a look at the additions (first approach) or at the difference between those two patches (second approach). For the latter, a side-by-side tool is recommended.

2023-12-20Makefile.extrawarn: turn on missing-prototypes globallyArnd Bergmann1-2/+2
Over the years we went from > 1000 of warnings to under 100 earlier this year, and I sent patches to address all the ones that I saw with compile testing randcom configs on arm64, arm and x86 kernels. This is a really useful warning, as it catches real bugs when there are mismatched prototypes. In particular with kernel control flow integrity enabled, those are no longer allowed. I have done extensive testing to ensure that there are no new build errors or warnings on any configuration of x86, arm and arm64 builds. I also made sure that at least both the normal defconfig and an allmodconfig build is clean for arc, csky, loongarch, m68k, microblaze, openrisc, parisc, powerpc, riscv, s390, and xtensa, with the respective maintainers doing most of the patches. At this point, there are five architectures with a number of known regressions: alpha, nios2, mips, sh and sparc. In the previous version of this patch, I had turned off the missing prototype warnings for the 15 architectures that still had issues, but since there are only five left, I think we can leave the rest to the maintainers (Cc'd here) as well.

2023-12-15scripts/kernel-doc: restore warning for Excess struct/unionRandy Dunlap1-0/+7
The warning for Excess struct or union member description was removed when the $nested parameter of check_sections() was removed. This causes some kernel-doc notation warnings to be missed. Recently the kernel test robot somehow reported an Excess member. The code in kernel-doc has not issued that warning since kernel v4.16, so I don't know how the robot did it. (See the Link for the report.) drivers/net/wireless/intel/iwlwifi/fw/dbg.c:86: warning: Excess struct/union/enum/typedef member 'trans_len' description in 'iwl_fw_dump_ptrs' I patched that warning away even though I could not reproduce the warning from kernel-doc. The warning should be issued for extraneous struct member or union member description, so restore it.

2023-12-14rust: Suppress searching builtin sysrootMatthew Maurer1-0/+1
By default, if Rust is passed `--target=foo` rather than a target.json file, it will infer a default sysroot if that component is installed. As the proposed aarch64 support [1] uses `aarch64-unknown-none` rather than a target.json file, this is needed [2] to prevent rustc from being confused between the custom kernel sysroot and the pre-installed one. [ Miguel: Applied Boqun's extra case (for `rusttest`) and reworded to add links to the arm64 patch series discussion. In addition, fixed the `rustdoc` target too (which requires a conditional since `cmd_rustdoc` is also used for host crates like `macros`). ] Signed-off-by: Matthew Maurer <mmaurer@google.com> Tested-by: Boqun Feng <boqun.feng@gmail.com> Reviewed-by: Alice Ryhl <aliceryhl@google.com> Link: https://lore.kernel.org/rust-for-linux/20231020155056.3495121-1-Jamie.Cunliffe@arm.com/ [1] Link: https://lore.kernel.org/rust-for-linux/CAGSQo01pOixiPXkW867h4vPUaAjtKtHGKhkV-rpifJvKxAf4Ww@mail.gmail.com/ [2] Link: https://lore.kernel.org/r/20231031201752.1189213-1-mmaurer@google.com Signed-off-by: Miguel Ojeda <ojeda@kernel.org>
