Notes from the meeting, next one in three weeks (January 4th). Happy 
holidays!
# Mirage 2022-12-14

participants: christiano, talex5, palainp, reynir, hannes

## qubes-mirage-firewall security issue
- two years after going from Mini-OS (PV) to solo5 (PVH), there was a 
denial of service for console output
- an infinite loop in console output when the output was too big (not 
fitting into a single write on xen)
- the change was changing "=" to "+="
- lead to a security advisory, CVE 2022 46770, MSA03

## mirage.4.3.2 released

## mirage-kv 6.0.0
- optint
- allocate function to reserve space. Use case is e.g. partial writes 
when downloading files over http - use less memory.
## Hillingar: MirageOS Unikernels on NixOS

- https://ryan.freumh.org/blog/hillingar/

## Mirage on OCaml 5

- PR for OCaml-solo5 https://github.com/mirage/ocaml-solo5/pull/122
- still some segfaults, needs further work
- christiano solo5 and multicore still of interest

## TCP benchmark for the qubes firewall

- christiano: maybe reordering?
- nobody had time to work on it

## next meeting: January 4h 2023 14:00 CET
