iscsid crash on logout - Catalina

[armandckj]

Hi.
Beta 6 installed. (exactly the same issue with Beta 5)
iscsictl gives a segmentation fault. used a build form latest sources iscsictl to overcome that.
iMac 2012 27 inch. Catalina with all updates.

I can login/logout about 10 to 20 times.
always, on the logout the system crashes. Back screen reboot and the text saying it crashed in different languages.
sometimes the crash is in the crash report but most of the time it is not.

included the report sent to Apple.

@armandckj, apologies for a bit off-topic... I'm considering giving this project a shot on my new/Catalina MBP. Do you recommend doing so? I'm wondering given no commits in two years and no response to this ticket in over a month.

Hi. I found that is would crash my imac’s after between 20-30 unmounts. I bought daemon tools iscsi initiator . $8 a copy. This has no command line interface which is a pity. Kernsafe iscsi initiator is also free but one mount only.

@armandckj @willhaslett Thanks for your comments. Development is on hold because Apple is going to make kernel extensions obsolete. They are shifting from IOKit-based drivers to DriverKit. Currently, the networking stack used by this project can shift to DriverKit but the SCSI portions cannot (Apple has not yet ported the SCSI classes to DriverKit). Furthermore, it is unclear what will and will not be ported - it seems like things are in a bit of a transition.

For this reason, it is highly likely that the architecture and code base will need to change to accommodate future versions of macOS.

As far as I can tell, there appear to some corner-case bugs. As a single developer, it is time-intensive to reproduce the issue (if I could readily reproduce it, the fix would be straightforward). Without the support of developer-users who can assist with this process, I am inclined to wait to see what happens with macOS kernel development frameworks (especially with the upcoming Big Sur), as we will have to go through this process again if the code base changes significantly.
