The branch stable/13 has been updated by oshogbo: URL: https://cgit.FreeBSD.org/src/commit/?id=e7a3a08febd01c95b74185bb971ec29cca64b8e1 commit e7a3a08febd01c95b74185bb971ec29cca64b8e1 Author: Mariusz Zaborski <oshogbo@FreeBSD.org> AuthorDate: 2023-04-21 07:50:16 +0000 Commit: Mariusz Zaborski <oshogbo@FreeBSD.org> CommitDate: 2023-05-02 12:21:35 +0000 mpr: fix copying of event_mask Before the commit 6cc44223cb6717795afdac4348bbe7e2a968a07d the field event_mask was fully copied to the EventMasks field. After this commit the event_mask (uint8_t) is 4 times casted to EventMask (uint32_t). Because of that 24 bits of each event_mask array is lost. This commits brings back simple copying of field, and after words converting 32 bits field to the requested endian. I don't think we need more sophisticated method, as the array is of size 4 (for 32 bits version). Reviewed by: imp MFC after: 1 week Sponsored by: Klara Inc.
