2025-07-15docs: kdoc: Regularize the use of the declaration nameJonathan Corbet2-30/+15
Each declaration type passes through the name in a unique field of the "args" blob - even though we have always just passed the name separately. Get rid of all the weird names and just use the common version. Reviewed-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2025-07-15docs: kdoc: Coalesce parameter-list handlingJonathan Corbet3-67/+43
Callers to output_declaration() always pass the parameter information from self.entry; remove all of the boilerplate arguments and just get at that information directly. Formalize its placement in the KdocItem class. It would be nice to get rid of parameterlist as well, but that has the effect of reordering the output of function parameters and struct fields to match the order in the kerneldoc comment rather than in the declaration. One could argue about which is more correct, but the ordering has been left unchanged for now.

2025-07-15docs: kdoc: remove the "struct_actual" machineryJonathan Corbet1-30/+2
The code goes out of its way to create a special list of parameters in entry.struct_actual that is just like entry.parameterlist, but with extra junk. The only use of that information, in check_sections(), promptly strips all the extra junk back out. Drop all that extra work and just use parameterlist. No output changes.

2025-07-14rust: use `#[used(compiler)]` to fix build and `modpost` with Rust >= 1.89.0Miguel Ojeda1-1/+2
Starting with Rust 1.89.0 (expected 2025-08-07), the Rust compiler fails to build the `rusttest` target due to undefined references such as: kernel...-cgu.0:(.text....+0x116): undefined reference to `rust_helper_kunit_get_current_test' Moreover, tooling like `modpost` gets confused: WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/gpu/drm/nova/nova.o ERROR: modpost: missing MODULE_LICENSE() in drivers/gpu/nova-core/nova_core.o The reason behind both issues is that the Rust compiler will now [1] treat `#[used]` as `#[used(linker)]` instead of `#[used(compiler)]` for our targets. This means that the retain section flag (`R`, `SHF_GNU_RETAIN`) will be used and that they will be marked as `unique` too, with different IDs. In turn, that means we end up with undefined references that did not get discarded in `rusttest` and that multiple `.modinfo` sections are generated, which confuse tooling like `modpost` because they only expect one. Thus start using `#[used(compiler)]` to keep the previous behavior and to be explicit about what we want. Sadly, it is an unstable feature (`used_with_arg`) [2] -- we will talk to upstream Rust about it. The good news is that it has been available for a long time (Rust >= 1.60) [3]. The changes should also be fine for previous Rust versions, since they behave the same way as before [4]. Alternatively, we could use `#[no_mangle]` or `#[export_name = ...]` since those still behave like `#[used(compiler)]`, but of course it is not really what we want to express, and it requires other changes to avoid symbol conflicts.

2025-07-10Merge branch 'virtio_udp_tunnel_08_07_2025' of ↵Jakub Kicinski1-0/+1
https://github.com/pabeni/linux-devel Paolo Abeni says: ==================== virtio: introduce GSO over UDP tunnel Some virtualized deployments use UDP tunnel pervasively and are impacted negatively by the lack of GSO support for such kind of traffic in the virtual NIC driver. The virtio_net specification recently introduced support for GSO over UDP tunnel, this series updates the virtio implementation to support such a feature. Currently the kernel virtio support limits the feature space to 64, while the virtio specification allows for a larger number of features. Specifically the GSO-over-UDP-tunnel-related virtio features use bits 65-69. The first four patches in this series rework the virtio and vhost feature support to cope with up to 128 bits. The limit is set by a define and could be easily raised in future, as needed. This implementation choice is aimed at keeping the code churn as limited as possible. For the same reason, only the virtio_net driver is reworked to leverage the extended feature space; all other virtio/vhost drivers are unaffected, but could be upgraded to support the extended features space in a later time. The last four patches bring in the actual GSO over UDP tunnel support. As per specification, some additional fields are introduced into the virtio net header to support the new offload. The presence of such fields depends on the negotiated features. New helpers are introduced to convert the UDP-tunneled skb metadata to an extended virtio net header and vice versa. Such helpers are used by the tun and virtio_net driver to cope with the newly supported offloads. Tested with basic stream transfer with all the possible permutations of host kernel/qemu/guest kernel with/without GSO over UDP tunnel support. ==================== Link: https://patch.msgid.link/cover.1751874094.git.pabeni@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-07-10scripts/gdb/symbols: make lx-symbols skip the s390 decompressorIlya Leoshkevich1-0/+26
When one starts QEMU with the -S flag and attaches GDB, the kernel is not yet loaded, and the current instruction is an entry point to the decompressor. In case the intention is to debug the early kernel boot, and not the decompressor, e.g., put a breakpoint on some kernel function and see all the invocations, one has to skip the decompressor. There are many ways to do this, and so far people wrote private scripts or memorized certain command sequences. Make it work out of the box like this: $ gdb -ex 'target remote :6812' -ex 'source vmlinux-gdb.py' vmlinux Remote debugging using :6812 0x0000000000010000 in ?? () (gdb) lx-symbols loading vmlinux (gdb) x/i $pc => 0x3ffe0100000 <startup_continue>: lghi %r2,0 Implement this by reading the address of the jump_to_kernel() function from the lowcore, and step until DAT is turned on.

2025-07-09checkpatch: check for missing sentinels in ID arraysBrian Norris1-0/+28
All of the ID tables based on <linux/mod_devicetable.h> (of_device_id, pci_device_id, ...) require their arrays to end in an empty sentinel value. That's usually spelled with an empty initializer entry (e.g., "{}"), but also sometimes with explicit 0 entries, field initializers (e.g., '.id = ""'), or even a macro entry (like PCMCIA_DEVICE_NULL). Without a sentinel, device-matching code may read out of bounds. I've found a number of such bugs in driver reviews, and we even occasionally commit one to the tree. See commit 5751eee5c620 ("i2c: nomadik: Add missing sentinel to match table") for example. Teach checkpatch to find these ID tables, and complain if it looks like there wasn't a sentinel value. Test output: $ git format-patch -1 a0d15cc47f29be6d --stdout | scripts/checkpatch.pl - ERROR: missing sentinel in ID array #57: FILE: drivers/i2c/busses/i2c-nomadik.c:1073: +static const struct of_device_id nmk_i2c_eyeq_match_table[] = { { .compatible = "XXXXXXXXXXXXXXXXXX", .data = (void *)(NMK_I2C_EYEQ_FLAG_32B_BUS | NMK_I2C_EYEQ_FLAG_IS_EYEQ5), }, }; total: 1 errors, 0 warnings, 66 lines checked NOTE: For some of the reported defects, checkpatch may be able to mechanically convert to the typical style using --fix or --fix-inplace. "[PATCH] i2c: nomadik: switch from of_device_is_compatible() to" has style problems, please review. NOTE: If any of the errors are false positives, please report them to the maintainer, see CHECKPATCH in MAINTAINERS. When run across the entire tree (scripts/checkpatch.pl -q --types MISSING_SENTINEL -f ...), false positives exist: * where macros are used that hide the table from analysis (e.g., drivers/gpu/drm/radeon/radeon_drv.c / radeon_PCI_IDS). There are fewer than 5 of these. * where such tables are processed correctly via ARRAY_SIZE() (fewer than 5 instances). This is by far not the typical usage of *_device_id arrays. * some odd parsing artifacts, where ctx_statement_block() seems to quit in the middle of a block due to #if/#else/#endif. Also, not every "struct *_device_id" is in fact a sentinel-requiring structure, but even with such types, false positives are very rare.

2025-07-09scripts/gdb: fix interrupts.py after maple tree conversionFlorian Fainelli4-6/+293
In commit 721255b9826b ("genirq: Use a maple tree for interrupt descriptor management"), the irq_desc_tree was replaced with a sparse_irqs tree using a maple tree structure. Since the script looked for the irq_desc_tree symbol which is no longer available, no interrupts would be printed and the script output would not be useful anymore. In addition to looking up the correct symbol (sparse_irqs), a new module (mapletree.py) is added whose mtree_load() implementation is largely copied after the C version and uses the same variable and intermediate function names wherever possible to ensure that both the C and Python version be updated in the future. This restores the scripts' output to match that of /proc/interrupts.

2025-07-08docs: kdoc: rework type prototype parsingJonathan Corbet1-18/+25
process_proto_type() is using a complex regex and a "while True" loop to split a declaration into chunks and, in the end, count brackets. Switch to using a simpler regex to just do the split directly, and handle each chunk as it comes. The result is, IMO, easier to understand and reason about. The old algorithm would occasionally elide the space between function parameters; see struct rng_alg->generate(), foe example. The only output difference is to not elide that space, which is more correct.

2025-07-02fs: introduce file_getattr and file_setattr syscallsAndrey Albershteyn1-0/+2
Introduce file_getattr() and file_setattr() syscalls to manipulate inode extended attributes. The syscalls takes pair of file descriptor and pathname. Then it operates on inode opened accroding to openat() semantics. The struct file_attr is passed to obtain/change extended attributes. This is an alternative to FS_IOC_FSSETXATTR ioctl with a difference that file don't need to be open as we can reference it with a path instead of fd. By having this we can manipulated inode extended attributes not only on regular files but also on special ones. This is not possible with FS_IOC_FSSETXATTR ioctl as with special files we can not call ioctl() directly on the filesystem inode using fd. This patch adds two new syscalls which allows userspace to get/set extended inode attributes on special files by using parent directory and a path - *at() like syscall.

2025-07-02kconfig: gconf: remove GtkHandleBox from gladeMasahiro Yamada1-9/+0
GtkHandleBox is deprecated with GTK 3.4. [1] [1]: https://gitlab.gnome.org/GNOME/gtk/-/blob/3.4.0/gtk/deprecated/gtkhandlebox.c#L426 Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: use gtk_dialog_get_content_area() accessorMasahiro Yamada1-2/+3
GTK 3 removes many implementation details and struct members from its public headers. Use the gtk_check_menu_item_get_active() accessor. [1]: https://gitlab.gnome.org/GNOME/gtk/-/blob/2.24.33/docs/reference/gtk/compiling.sgml#L85 Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

GTK 3 removes many implementation details and struct members from its public headers. Use the gtk_check_menu_item_get_active() accessor. [1]: https://gitlab.gnome.org/GNOME/gtk/-/blob/2.24.33/docs/reference/gtk/compiling.sgml#L85 Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: remove unnecessary default message in text viewMasahiro Yamada1-1/+0
This message looks odd because it is displayed when nothing is selected. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: replace "tooltip" property with "tooltip-text"Masahiro Yamada1-17/+17
This is no longer available in GTK 3. Use "tooltip-text" instead. Also reword "Goes up of one level" to "Goes up one level" while I am here. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: remove "tooltips" property from gladeMasahiro Yamada1-1/+0
The tips are still displayed without this. This property does not exist in GtkBuilder with GTK 3. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: replace GTK_STOCK_{OK,NO,CANCEL}Masahiro Yamada1-3/+3
These are deprecated with GTK 3.10. [1] Use "_OK", "_no", "_Cancel". [1]: https://gitlab.gnome.org/GNOME/gtk/-/blob/3.10.0/gtk/deprecated/gtkstock.h#L827 Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: replace GDK_space with GDK_KEY_spaceMasahiro Yamada1-1/+1
In GTK3, keysyms changed to have a KEY_ prefix. [1]: https://gitlab.gnome.org/GNOME/gtk/-/blob/2.24.33/gdk/gdkkeysyms-compat.h#L24 Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: remove dead code in display_tree_part()Masahiro Yamada1-4/+1
This function is no longer called in the FULL_VIEW mode, so remove the dead code. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: inline display_list() into set_view_mode()Masahiro Yamada1-11/+3
This function is now only called by set_view_mode(), so inline it for simplicity. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: do not reconstruct tree store when a symbol is changedMasahiro Yamada1-18/+11
There is no need to reconstruct the entire tree store when a symbol's value changes. Simply call gtk_tree_store_set() to update the row data. Introduce update_trees() to factor out the common update logic. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: inline fill_row() into set_node()Masahiro Yamada1-166/+106
The row[] array is used to prepare data passed to set_node(), but this indirection is unnecessary. Squash fill_row() into set_node() and call gtk_tree_store_set() directly. Also, calling gdk_pixbuf_new_from_xpm_data() for every row is inefficient. Call it once and store the resulting pixbuf in a global variable. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: remove init_tree_model()Masahiro Yamada1-20/+16
Move the relevant code into init_left_tree() or init_right_tree(). Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: remove global 'model1' and 'model2' variablesMasahiro Yamada1-5/+2
These variables are unnecessary because the current model can be retrieved using gtk_tree_view_get_model(). Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Acked-by: Randy Dunlap <rdunlap@infradead.org>
2025-07-02kconfig: gconf: use GtkTreeModelFilter to control row visibilityMasahiro Yamada1-137/+80
Currently, update_tree() adds/removes entries to show/hide rows. This approach is extremely complicated. Use the tree model filter to control row visibility instead. Do not toggle the MENU_CHANGED flag, as it is hard to control this correctly. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: preserve menu selection when switching view modeMasahiro Yamada1-8/+79
Preserve the current menu selection when switching to a different view mode, as it improves usability. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: merge 'current' and 'browsed' global variablesMasahiro Yamada1-19/+13
The 'current' (SINGLE view) and 'browsed' (SPLIT_VIEW) variables serve similar purposes and are not needed at the same time. Merge them. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: remove global 'tree' variableMasahiro Yamada1-21/+21
Pass the tree store as a function parameter to make it clearer which tree is being updated. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-07-02kconfig: gconf: make introduction, about, license dialogs modalMasahiro Yamada1-12/+6
These are modal dialogs in xconfig. Make them modal in gconfig as well. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Acked-by: Randy Dunlap <rdunlap@infradead.org> Tested-by: Randy Dunlap <rdunlap@infradead.org>
