Subject: [PATCH v2 0/3] floppy: suppress UBSAN warning in setup_rw_floppy()
Date: Sun, 26 Apr 2020 16:07:25 +0300 [thread overview]
Message-ID: <20200426130728.63399-1-efremov@linux.com> (raw)
These patches are based on Willy's cleanup patches
https://lkml.org/lkml/2020/3/31/609.
The first two patches indroduce defines to make it more clear why
cmd_count in struct floppy_raw_cmd allows out-of-bounds access for
cmd, reply_count, reply fields. The last one handles the warning.
Changes in v2:
- add FD_RAW_CMD_FULLSIZE to the second patch
- add union with fullcmd to struct floppy_raw_cmd in the last patch
Denis Efremov (3):
floppy: add FD_AUTODETECT_SIZE define for struct floppy_drive_params
floppy: add defines for sizes of cmd & reply buffers of floppy_raw_cmd
floppy: suppress UBSAN warning in setup_rw_floppy()
