From: Carsten Otte <cotte at de.ibm.com> From: Christian Borntraeger <borntraeger at de.ibm.com> This patch introduces in-kernel handling of _some_ sigp interprocessor signals (similar to ipi). kvm_s390_handle_sigp() decodes the sigp instruction and calls individual handlers depending on the operation requested: - sigp sense tries to retrieve information such as existence or running state of the remote cpu - sigp emergency sends an external inter...

...RUPT which is valid for both the vm file descriptors and the vcpu file descriptors. In case this ioctl is issued against a vm file descriptor, the interrupt is considered floating. Floating interrupts may be delivered to any virtual cpu in the configuration. The following interrupts are supported: SIGP STOP - interprocessor signal that stops a remote cpu SIGP SET PREFIX - interprocessor signal that sets the prefix register of a (stopped) remote cpu INT EMERGENCY - interprocessor interrupt, usually used to signal need_reshed and for smp_call_function() i...

I'm not on the mailing list, so I'd appreciate it if you could cc: me, though I will keep an eye on the archives. I am running openssh 2.2.0p1 on Debian GNU/Linux. I was pleased to see that 2.2.0p1 had support for DSA keys in the agent, and I have successfully used the v2 protocol to another openssh server with the agent providing authentication. I am also able to successfully connect

Functionality request for supporting Digital Signatures for RSA and DSS Public Key Algorithms in alignment with NIST SP800-131A. I assume this has been asked before, but I could not find in the archives. Support of "ssh-rsa-sha256" and "ssh-dss-sha256" public key algorithms for OpenSSH? I know Suite B Algorithms and x509 SSH Extension Algorithms are supported, but not a

I've architected this in a way that looks future proof at least to the openssl provider transition. What will happen in openssl 3.0.0 is that providers become active and will accept keys via URI. The current file mechanisms will still be available but internally it will become a file URI. To support the provider interface, openssl will have to accept keys by URI instead of file and may

I have just uploaded a new snapshot to: http://www.mindrot.org/misc/openssh/openssh-SNAP-20001114.tar.gz This snapshot includes Markus Friedl's new SSH2 RSA authentication work and -R portforwarding for SSH2. Please give these a good test. The new RSA authentications works similar to the current SSH2 DSA keys, but requires a little modification to config files. Currently RSA key cannot be

I'm sending a first draft of my proposed cpu hotplug driver for kvm/virtio The first patch is the kernel module, while the second, the userspace pci device. The host boots with the maximum cpus it should ever use, through the -smp parameter. Due to real machine constraints (which qemu copies), i386 does not allow for any addition of cpus after boot, so this is the most general way. I do
