sg_turs : bad pass-through setup

[aagon]

See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1118528 :

However, since upgrading to trixie, calling sg_turs against my optical
drives fails to work correctly:

$ sg_turs /dev/sr0 ; echo $?
Test unit ready: bad pass-through setup
0

I am not the original reporter of the debian bug, but I can confirm the behaviour on different hardware (a magnetic tape reader):

# sg_turs /dev/nst0
Test unit ready: bad pass-through setup

As the original reported mentioned, adding "-l" makes things work again.

This behaviour was reproduced using upstream version 1.48, downloaded straight from https://sg.danny.cz/sg/sg3_utils.html, so it is not specific to debian.

Best,

I can confirm that I see that error in Debian 13 (Trixie) when sg_turs /dev/sr0 is invoked. The good news is that it doesn't happen now. It is the "sg_turs: fix missing CDB on several codepaths" entry in the ChangeLog for pre-release 1.49 that logs the fix. .The patch to fix it from this repo will be the git equivalent of 'svn diff -r 1052:1053 src/sg_turs.c' . There has been a minor addition to sg_turs.c since then that is not relevant to the issue (T10 added a "Not Ready, in progress" ASC/ASCQ code implying no operator intervention was required (just be patient)). The patch formed by that 'svn diff' (or the git equivalent) is what the debian maintainers should run with. Or maybe a stripped down version of that patch.
