Pull hardening updates from Kees Cook: "One of the more voluminous set of changes is for adding the new __counted_by annotation[1] to gain run-time bounds checking of dynamically sized arrays with UBSan. - Add LKDTM test for stuck CPUs (Mark Rutland) - Improve LKDTM selftest behavior under UBSan (Ricardo Cañuelo) - Refactor more 1-element arrays into flexible arrays (Gustavo A. R. Silva) - Analyze and replace strlcpy and strncpy uses (Justin Stitt, Azeem Shaikh) - Convert group_info.usage to refcount_t (Elena Reshetova) - Add __counted_by annotations (Kees Cook, Gustavo A.

drbd: Annotate struct fifo_buffer with __counted_by

2023-10-02T16:48:52Z

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct fifo_buffer.

drbd: Add peer device parameter to whole-bitmap I/O handlers

2023-04-02T02:27:55Z

Pass a peer device parameter through the bitmap I/O functions to the I/O handlers. In after_state_ch(), set that parameter when queuing the drbd_send_bitmap operation so that this operation knows where to send the bitmap.

drbd: remove macros using require_context

2023-01-29T22:18:33Z

This require_context attribute originated in a proposed sparse patch by Philipp Reisner back in 2008. Johannes Berg had a different solution to a similar problem, and that patch "won" in the end; so the require_context thing never got merged. The whole history can be read at [0]. DRBD kept using these annotations anyway for a while. Nowadays, on a modern unmodified sparse, they obviously do nothing, and they are hardly used anymore anyway. So, just remove the definitions of these macros.
