lkdtm: Use init_uts_ns.name instead of macros

2021-09-10T15:09:40+00:00

Using generated/compile.h triggered a full LKDTM rebuild with every build. Avoid this by using the exported strings instead.

lkdtm: remove IDE_CORE_CP crashpoint

2021-08-19T05:40:22+00:00

With the removal of the legacy IDE driver in kb7fb14d3ac63 ("ide: remove the legacy ide driver"), this crashpoint no longer points to a valid function.

lkdtm: replace SCSI_DISPATCH_CMD with SCSI_QUEUE_RQ

2021-08-19T05:40:22+00:00

When scsi_dispatch_cmd was moved to scsi_lib.c and made static, some compilers (i.e., at least gcc 8.4.0) decided to compile this inline. This is a problem for lkdtm.ko, which inserted a kprobe on this function for the SCSI_DISPATCH_CMD crashpoint. Move this crashpoint one function up the call chain to scsi_queue_rq. Though this is also a static function, it should never be inlined because it is assigned as a structure entry. Therefore, kprobe_register should always be able to find it.

lkdtm/heap: Avoid __alloc_size hint warning for VMALLOC_LINEAR_OVERFLOW

2021-08-18T20:28:51+00:00

Once __alloc_size hints have been added, the compiler will (correctly!) see this as an overflow. We are, however, trying to test for this condition at run-time (not compile-time), so work around it with a volatile int offset.

lkdtm: Add kernel version to failure hints

2021-08-18T20:28:51+00:00

In an effort to keep as much information in once place as possible in CI logs, report the kernel version and architecture in the failure hints.

lkdtm/fortify: Consolidate FORTIFY_SOURCE tests

2021-08-18T20:28:51+00:00

The FORTIFY_SOURCE tests were split between bugs.c and fortify.c. Move tests into fortify.c, standardize their naming, add CONFIG hints, and add them to the lkdtm selftests.

lkdtm/bugs: Add ARRAY_BOUNDS to selftests

2021-08-18T20:28:51+00:00

Add CONFIG hints about why the ARRAY_BOUNDS test might fail, and similarly include the CONFIGs needed to pass the ARRAY_BOUNDS test via the selftests, and add to selftests.

Pull char / misc driver updates from Greg KH: "Here is the big set of char / misc and other driver subsystem updates for 5.14-rc1. Included in here are: - habanalabs driver updates - fsl-mc driver updates - comedi driver updates - fpga driver updates - extcon driver updates - interconnect driver updates - mei driver updates - nvmem driver updates - phy driver updates - pnp driver updates - soundwire driver updates - lots of other tiny driver updates for char and misc drivers This is looking more and more like the "various driver subsystems mushed together" tree...
