Now that everything has been set to go as described in Part 1 (Key technical obstacles for Live Patching Meltdown), Part 2 (Virtual address mappings and the Meltdown vulnerability)  and Part 3 (Changes needed for Translation Lookaside Buffer (TLB) flushing primitives), the last missing piece is to actually replace the entry code and make it […]

Building upon the Part 1 (Key technical obstacles for Live Patching Meltdown) and the Part 2 (Virtual address mappings and the Meltdown vulnerability), let’s now address the needed changes to the TLB flushing primitives. In order to resolve virtual to physical addresses, a CPU must traverse the page table tree. This is a costly thing to […]

Following up on the Part 1 about key technical obstacles for Live Patching Meltdown, in this blog I will give you some background on virtual address mappings in context of the Meltdown vulnerability and look at patching kGraft itself! Virtually mapped memory is a protection feature provided by the CPU, orthogonal to the privilege separation […]

As a system administrator, you could be spending several man days each month applying patches, synchronizing the patches across all your systems and rebooting the systems. You can avoid this. On average, infrastructure failure costs large enterprises $100,000 per hour. Critical application failures can cost $500,000 to $1 million per hour*. You can avoid kernel […]

SUSE just extended Live Patching to IBM Power Systems. Driven by customer demand, this is yet another stellar step toward zero downtime that IBM Power customers want, need, and have asked SUSE to provide. Building on the success of Live Patching for the x86 platform, SUSE is the first to provide Live Patching for IBM […]
