VirtualSquare general topics
Packetize new versions of our tools and libraries.
Add contents (tutorials, guides) to: http://wiki.virtualsquare.org
Test experiemnts on the tutorial image: http://wiki.virtualsquare.org/#!tutorials/intro.md
nsutils: guide.
Virtual Networking
open question: vdens/vdestack is based on user namespaces... It is the case to port all the tools on user namespaces? Are them so widely adopted that the general public will use the new tools.
vdetelweb: new design (generalization of dynamic management of web pages and command auto-completion based on help messages)
vdetelweb: re-design vdetelweb on vde-stack.
VDE-4 switch, wirefilter...
libslirp: projects convergence towards a unified library (Fabbri)
Cado/scado: packets + cmake (Berardi Biondi)
hashdns has been designed to give authoritative replies but it does not forward requests. In a scenario where all IoT/IoTh have public addresses and names, hashdns works well, but we need either to implement a forwarding service or to study a configuration for an external forwarder (dnsmasq? bind?) to support hash based DNS resolutions for private networks. hashdns refactoring (Balestra)
hashdns and fqdndhcp use syncronous access to the DNS server, this could slow down the service in case of bursts of requests. Implementations based on queues and asynchronous mapping of requests/replies should perform better.
fqdndhcp lease time is a constant, should be configurable
vxvde/vxvdex: BPF to filter spurious multicast self packets.
Performance analysis of vxvde using ....
exotcp: update and benchmarks...
test vde4 using jumboframes
study vde vs. n2n
virtual stacks
full integration in the v2 architecture of picotcp
full integration in the v2 architecture of pycotcp
LWIPv6: convergence to lwip? new fork? (Berlingeri)
Partial Virtual Machines
Seccomp EBPF + kernel code offloading. (Di Stefano)
Purelibc library: update or reimplement? (glibc architecture?)
Ptrace for umvu?
vufuse integration - hybrid libs (Fulgaro)
vufuseiso vufusefat
vufs debugging
vuos: model for permission enforcement.
short path for exceptions.
Mount options unified management (no errors on mistypes now)
VIrtual access syscall.
Management of posix acl
management of file capabilities.
blocking ioctl
info on processes (angels drawback)
vunet+user mode tcp-ip
