[ Original Bug Description ] Package: sg3-utils 1.48-3ubuntu3 Ubuntu: 26.04 (Resolute Raccoon) Binary: sg_wr_mode version "1.30 20230623" sg_wr_mode rejects every --contents= and --cfile= argument before opening the target device, regardless of value. The rejection fires from argv parsing — it's not device-specific. Repro (any of these): $ sg_wr_mode --page=8 --contents=0,1 /dev/null bad argument to '--contents=' $ sg_wr_mode --page=8 --contents="08 12 01" /dev/null bad argument to '--contents=' $ sg_wr_mode -p 8 -c 08,12,01 /dev/null bad argument to '--contents=' $ printf '\x08\x12\x01' > /tmp/page.bin $ sg_wr_mode --page=8 --cfile=/tmp/page.bin /dev/null bad argument to '--cfile=' Exit code: 32 in every case. strace confirms the failure is pre-I/O: libsgutils2-1.48.so.2 loads, then the error is written to stderr and the process exits — the device is never opened. So the bug is in sg_wr_mode's argv handler, not the underlying SCSI layer. Confirmed not device-related: same failure against /dev/sg1 (a QEMU CD- ROM SCSI generic device). sg_inq and sg_modes against the same device work normally — only sg_wr_mode's argument parser rejects --contents=. The sg3-utils library and the device are both healthy; the bug is isolated to sg_wr_mode. Workaround: issue MODE SELECT(10) directly via sg_raw, e.g.: sg_raw -v -s 28 -i payload.bin /dev/sgN 55 10 00 00 00 00 00 00 1C 00 Expected: --contents= should accept the documented "comma-separated string of hex numbers (00..ff)" syntax (per the man page and --help text). Actual: every value is rejected.
