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
