Tru64 AdvFS porting to NetBSD - 1. status 2014-09-17

[Kamil Rytarowski]

Hello,

This is the first status of significant efforts of porting AdvFS [1] [2] to NetBSD.

Long term primary goals:
- complete port of AdvFS to NetBSD,
- relicense the original work with for BSD-friendly license.

1. What is done
- Put all sbin, usr.sbin and lib files into the NetBSD tree
- Add AdvFS user-space parts to initial Makefiles of build.sh
- Add initial variable MKADVFS to stop or start building user-land pieces
- Put kernel-space code into the tree (sys/fs/msfs/)
- Add msfs (aka AdvFS) to the kernel build-machinery and include it for amd64 kernel "ALL"
- Adapted for NetBSD or nuked missing #includes of files from sys/fs/msfs
2. What is in progress
- Party adapted locking dialect (mutex, krwmutex, condvar) for NetBSD (*)
- List of compatibility patches adapting for modern GCC and NetBSD (*)
- Researched and touched compatibility of catgen from NetBSD and Tru64
3. Issues
- Missing subsystems from Tru64: evm.h, devio, overlap.h (added an empty stub), disklabel details (*)
4. Next steps
- Tru64 Mach VM dialect porting to NetBSD UVM (*)
5. Pushed to NetBSD
- Proposed <sys/clock.h> patch [3]

(*) Considered significant effort and/or difficult.

Help and motivation support is appreciated.

I tried to get HP to dual license it but at the time they didn't care.

Please put the user part under external/<license>/{advfs or megasafe}/....

This should be in sys/external/<license>/{advfs or megasafe}/... like avobe

Mostly adapting the dec osf1 ubc to the netbsd ubc. It's been 2 decades since I last in the dec osf1 tree.

keep going. i liked advfs back in the day.

Hello,

Thank you for your feedback.

I will put the moving directories around onto my TODO stack.

Please let me do it after resolving thousands of lines of compilation errors (just the kernel-part). I will go for a 'msfs' external name.

When I will be done with making it buildable then I will contact the core team / foundation to help me to organize steps to relicense it.

With regards,

[Jochen Kunz]

AdvFS for NetBSD! A dream comes true. :-)
I liked AdvFS very much when I used Tru64 back in its days.
