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

thunderbolt: Update property.c function documentation

2025-09-17T05:32:59+00:00

Make property.c function documentation compliant with current kernel-doc standards. No functional changes. Signed-off-by: Alan Borzeszkowski Signed-off-by: Mika Westerberg

thunderbolt: Add tb_property_copy_dir()

2021-03-18T15:25:31+00:00

This function takes a deep copy of the properties. We need this in order to support more dynamic properties per XDomain connection as required by the USB4 inter-domain service spec. Signed-off-by: Mika Westerberg

thunderbolt: property: Fix a missing check of kzalloc

2019-03-28T08:30:47+00:00

No check is enforced for the return value of kzalloc, which may lead to NULL-pointer dereference. The patch fixes this issue. Signed-off-by: Kangjie Lu Reviewed-by: Mukesh Ojha Signed-off-by: Mika Westerberg

thunderbolt: Fix a missing check of kmemdup

2019-03-20T10:37:12+00:00

kmemdup may fail and return NULL. The fix adds a check and returns NULL in case it fails to avoid NULL pointer dereferecen. Signed-off-by: Kangjie Lu Signed-off-by: Mika Westerberg

thunderbolt: property: Fix a NULL pointer dereference

2019-03-20T10:37:12+00:00

In case kzalloc fails, the fix releases resources and returns -ENOMEM to avoid the NULL pointer dereference. Signed-off-by: Kangjie Lu Signed-off-by: Mika Westerberg

thunderbolt: Convert rest of the driver files to use SPDX identifier

2018-10-02T22:52:08+00:00

This gets rid of the licence boilerplate duplicated in each file. While there fix doubled space in domain.c author line. No functional changes intended. Signed-off-by: Mika Westerberg Acked-by: Yehezkel Bernat Signed-off-by: Greg Kroah-Hartman

thunderbolt: Add support for XDomain properties

2017-10-02T18:24:40+00:00

Thunderbolt XDomain discovery protocol uses directories which contain properties and other directories to exchange information about what capabilities the remote host supports. This also includes identification information like device ID and name. This adds support for parsing and formatting these properties and establishes an API drivers can use in addition to the core Thunderbolt driver. This API is exposed in a new header: include/linux/thunderbolt.h. This code is based on the work done by Amir Levy and Michael Jamet.
