Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using git grep -l '\

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

Input: tablet - use sizeof(*pointer) instead of sizeof(type)

2024-06-03T04:32:03+00:00

It is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter). This patch has no effect on runtime behavior.

Input: kbtab - sanity check for endpoint type

2019-08-01T17:55:21+00:00

The driver should check whether the endpoint it uses has the correct type. Reported-by: syzbot+c7df50363aaff50aa363@syzkaller.appspotmail.com Signed-off-by: Oliver Neukum Signed-off-by: Dmitry Torokhov

treewide: Add SPDX license identifier for more missed files

2019-05-21T08:50:45+00:00

Add SPDX license identifiers to all files which: - Have no license information of any form - Have MODULE_LICENCE("GPL*") inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

Input: inline macros for MODULE_LICENSE, etc

2018-01-17T17:52:22+00:00

Inline macro for MODULE_LICENSE to make the license information easy to find, eg with grep. Inline the other module-related macros at the same time. A simplified version of the semantic patch for the MODULE_LICENSE case is as follows: (http://coccinelle.lip6.fr/) // @s@ identifier i; expression e; @@ @@ declarer name MODULE_LICENSE; identifier s.i; expression s.e; @@ MODULE_LICENSE( - i + e ); // Signed-off-by: Julia Lawall [dtor: added a couple of drivers missed by the script, removed a few unused DRIVER_VERSION macros] Signed-off-by: Dmitry Torokhov

Input: remove unneeded DRIVER_LICENSE #defines

2018-01-17T00:47:33+00:00

There is no need to #define the license of the driver, just put it in the MODULE_LICENSE() line directly as a text string. This allows tools that check that the module license matches the source code license to work properly, as there is no need to unwind the unneeded dereference. For some of these drivers, the #define is just a few lines above the MODULE_LICENSE() line, which is extra pointless.

usb_device_id are not supposed to change at runtime. All functions working with usb_device_id provided by work with const usb_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav Signed-off-by: Dmitry Torokhov

Input: kbtab - validate number of endpoints before using them

Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer should a malicious device lack endpoints. Signed-off-by: Johan Hovold Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov
