2019-12-22kbuild: clarify the difference between obj-y and obj-m w.r.t. descendingMasahiro Yamada1-3/+13
Kbuild descends into a directory by either 'y' or 'm', but there is an important difference. Kbuild combines the built-in objects into built-in.a in each directory. The built-in.a in the directory visited by obj-y is merged into the built-in.a in the parent directory. This merge happens recursively when Kbuild is ascending back towards the top directory, then built-in objects are linked into vmlinux eventually. This works properly only when the Makefile specifying obj-y is reachable by the chain of obj-y. On the other hand, Kbuild does not take built-in.a from the directory visited by obj-m. This it, all the objects in that directory are supposed to be modular. If Kbuild descends into a directory by obj-m, but the Makefile in the sub-directory specifies obj-y, those objects are just left orphan. The current statement "Kbuild only uses this information to decide that it needs to visit the directory" is misleading. Clarify the difference.

This is a follow-up commit for the sysfs attributes to change from DRIVER_ATTR to DEVICE_ATTR according to some initial comments. In such case, it's better to point the sysfs path to the device itself instead of the driver. The ABI document is also updated.

2019-12-04kcov: remote coverage supportAndrey Konovalov1-0/+129
Patch series " kcov: collect coverage from usb and vhost", v3. This patchset extends kcov to allow collecting coverage from backgound kernel threads. This extension requires custom annotations for each of the places where coverage collection is desired. This patchset implements this for hub events in the USB subsystem and for vhost workers. See the first patch description for details about the kcov extension. The other two patches apply this kcov extension to USB and vhost. Examples of other subsystems that might potentially benefit from this when custom annotations are added (the list is based on process_one_work() callers for bugs recently reported by syzbot): 1. fs: writeback wb_workfn() worker, 2. net: addrconf_dad_work()/addrconf_verify_work() workers, 3. net: neigh_periodic_work() worker, 4. net/p9: p9_write_work()/p9_read_work() workers, 5. block: blk_mq_run_work_fn() worker. These patches have been used to enable coverage-guided USB fuzzing with syzkaller for the last few years, see the details here: https://github.com/google/syzkaller/blob/master/docs/linux/external_fuzzing_usb.md This patchset has been pushed to the public Linux kernel Gerrit instance: https://linux-review.googlesource.com/c/linux/kernel/git/torvalds/linux/+/1524 This patch (of 3): Add background thread coverage collection ability to kcov. With KCOV_ENABLE coverage is collected only for syscalls that are issued from the current process. With KCOV_REMOTE_ENABLE it's possible to collect coverage for arbitrary parts of the kernel code, provided that those parts are annotated with kcov_remote_start()/kcov_remote_stop(). This allows to collect coverage from two types of kernel background threads: the global ones, that are spawned during kernel boot in a limited number of instances (e.g. one USB hub_event() worker thread is spawned per USB HCD); and the local ones, that are spawned when a user interacts with some kernel interface (e.g. vhost workers). To enable collecting coverage from a global background thread, a unique global handle must be assigned and passed to the corresponding kcov_remote_start() call. Then a userspace process can pass a list of such handles to the KCOV_REMOTE_ENABLE ioctl in the handles array field of the kcov_remote_arg struct. This will attach the used kcov device to the code sections, that are referenced by those handles. Since there might be many local background threads spawned from different userspace processes, we can't use a single global handle per annotation. Instead, the userspace process passes a non-zero handle through the common_handle field of the kcov_remote_arg struct. This common handle gets saved to the kcov_handle field in the current task_struct and needs to be passed to the newly spawned threads via custom annotations. Those threads should in turn be annotated with kcov_remote_start()/kcov_remote_stop(). Internally kcov stores handles as u64 integers. The top byte of a handle is used to denote the id of a subsystem that this handle belongs to, and the lower 4 bytes are used to denote the id of a thread instance within that subsystem. A reserved value 0 is used as a subsystem id for common handles as they don't belong to a particular subsystem. The bytes 4-7 are currently reserved and must be zero. In the future the number of bytes used for the subsystem or handle ids might be increased. When a particular userspace process collects coverage by via a common handle, kcov will collect coverage for each code section that is annotated to use the common handle obtained as kcov_handle from the current task_struct. However non common handles allow to collect coverage selectively from different subsystems.

2019-12-04docs/core-api: Remove possibly confusing sub-headings from Bit OperationsMichael Ellerman1-9/+0
The recent commit 81d2c6f81996 ("kasan: support instrumented bitops combined with generic bitops"), split the KASAN instrumented bitops into separate headers for atomic, non-atomic and locking operations. This was done to allow arches to include just the instrumented bitops they need, while also using some of the generic bitops in asm-generic/bitops (which are automatically instrumented). The generic bitops are already split into atomic, non-atomic and locking headers. This split required an update to kernel-api.rst because it included include/asm-generic/bitops-instrumented.h, which no longer exists. So now kernel-api.rst includes all three instrumented headers to get the definitions for all the bitops. When adding the three headers it seemed sensible to add sub-headings for each, ie. "Atomic", "Non-atomic" and "Locking". The confusion is that test_bit() is (and always has been) in non-atomic.h, but is documented elsewhere (atomic_bitops.txt) as being atomic. So having it appear under the "Non-atomic" heading is possibly confusing. Probably test_bit() should move from bitops/non-atomic.h to atomic.h, but that has flow on effects. For now just remove the newly added sub-headings in the documentation, so we at least aren't adding to the confusion about whether test_bit() is atomic or not.
