Although I can't reproduce, I seem to have had an incomplete transfer which wasn't picked up by the existing error handling. This change adds some more sanity checks: * Check for error on close() (should have been doing this anyway) * Check that the bytes received == reported content length --- lib/Sys/VirtV2V/Transfer/ESX.pm | 14 +++++++++++++- 1 files changed, 13 insertions(+), 1

Hi all, attached is a patch that enables using hardware crypto accelerators available through OpenSSL library for SSH operations. Especially in ssh/sshd it can bring a significant speed improvement. OTOH if no crypto engine is available, nothing bad happens and default software crypto routines are used. This patch is used in SUSE Linux OpenSSH package and proved to work (at least it didn't

If have a couple patches I found while looking at a panic I was seeing while unloading the nouveau module. Unloading the nouveau module on my optimus notebook machine causes the system to panic. This started occuring when moving from 4.4 to 4.14. These patches make it such that the system does not panic when unloading the module. 4.14 also requires commit 34112bf4935d ("drm/nouveau/fbcon:

During the review of "[PATCH] vsock/virtio: Initialize core virtio vsock before registering the driver", Stefan pointed out some possible issues in the .probe() and .remove() callbacks of the virtio-vsock driver. This series tries to solve these issues: - Patch 1 postpones the 'the_virtio_vsock' assignment at the end of the .probe() to avoid that some sockets queue works when

This patch adds support to find next 1 or 0 bit in a xbmitmap range and clear a range of bits. More possible optimizations to add in the future: 1) xb_set_bit_range: set a range of bits. 2) when searching a bit, if the bit is not found in the slot, move on to the next slot directly. 3) add tags to help searching.

This patch series enhances the existing virtio-balloon with the following new features: 1) fast ballooning: transfer ballooned pages between the guest and host in chunks using sgs, instead of one array each time; and 2) free page block reporting: a new virtqueue to report guest free pages to the host. The second feature can be used to accelerate live migration of VMs. Here are some details: Live
