...ease includes several fixes for the command line tool and lots of improvements for the daemon. Specifically I'd like to thank Hannes Eder, Vincent Jardin and Samuel Gauthier for their suggestions and contributions. Please, see changelog attached for more details. I'd also like to thank 6WIND <www.6wind.com> for sponsoring the development of two new features that are included in this release: the new TCP-based state-synchronization approach and a new feature that allows to disable the internal and the external caches. They have also helped auditing the code and doing bug hunti...

It doesn't just break your scripts (which counts as a regression), I think it's really wrong. The worker threads should show up as threads of the thing that started them, not as processes. So the...

...ct: ipset Version: unspecified Hardware: x86_64 OS: All Status: NEW Severity: enhancement Priority: P5 Component: default Assignee: netfilter-buglog at lists.netfilter.org Reporter: philippe.guibert at 6wind.com Today, it is possible to apply a subnet mask. ipset create foo hash:net family ipv6 ipset add foo 1001::0/112 The need is to use hexadecimal format of mask, to be able to create more subtle masks. This filter can be useful, if one wants to filter only on the last 4 bytes of the ipv6 address,...

Hi, i am working on the jailhouse[1] project and am currently looking at inter-VM communication. We want to connect guests directly with virtual consoles based on shared memory. The code complexity in the hypervisor should be minimal, it should just make the shared memory discoverable and provide a signaling mechanism. We would like to reuse virtio so that Linux-guests will eventually just work
