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

xen: make remove callback of xen driver void returned

2022-12-15T15:06:10+00:00

Since commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned, it doesn't make much sense for any bus based driver implementing remove callbalk to return non-void to its caller. This change is for xen bus based drivers.

xen: switch gnttab_end_foreign_access() to take a struct page pointer

2022-05-27T09:05:29+00:00

Instead of a virtual kernel address use a pointer of the associated struct page as second parameter of gnttab_end_foreign_access(). Most users have that pointer available already and are creating the virtual address from it, risking problems in case the memory is located in highmem. gnttab_end_foreign_access() itself won't need to get the struct page from the address again.

xen/grant-table: remove readonly parameter from functions

2022-03-16T01:34:40+00:00

The gnttab_end_foreign_access() family of functions is taking a "readonly" parameter, which isn't used. Remove it from the function parameters.

xen: add "not_essential" flag to struct xenbus_driver

2021-11-23T19:41:29+00:00

When booting the xenbus driver will wait for PV devices to have connected to their backends before continuing. The timeout is different between essential and non-essential devices. Non-essential devices are identified by their nodenames directly in the xenbus driver, which requires to update this list in case a new device type being non-essential is added (this was missed for several types in the past). In order to avoid this problem, add a "not_essential" flag to struct xenbus_driver which can be set to "true" by the respective frontend. Set this flag for the frontends currently regarded to be not essential (vkbs and vfb) and use it for testing in the xenbus driver.

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in this particular case, I placed the "fall through" part at the beginning of the code comment, which is what GCC is expecting to find.

Input: xen-kbdfront - allow better run-time configuration

2018-06-12T22:11:00+00:00

It is now only possible to control if multi-touch virtual device is created or not (via the corresponding XenStore entries), but keyboard and pointer devices are always created. In some cases this is not desirable. For example, if virtual keyboard device is exposed to Android then the latter won't automatically show on-screen keyboard as it expects that a physical keyboard device can be used for typing. Utilize keyboard and pointer device XenStore feature fields to configure which virtual devices are created: - set "feature-disable-keyboard" to 1 if no keyboard device needs to be created - set "feature-disable-pointer" to 1 if no pointer device needs to be created Keep old behavior by default.
