Live Kernel Patching Microconference Accepted into 2016 Linux Plumbers Conference

Live kernel patching was accepted into the Linux kernel in v4.0 in February 2015, so we can declare the 2014 LPC Live Kernel Patching Microconference to have been a roaring success! However, as was noted at the time, this is just the beginning of the real work. In short, the v4.0 work makes live kernel patching possible, but more work is required to make it more reliable and more routine.

Additional issues include stacktrace reliability, patch-safety criteria for kernel threads, thread consistency models, porting to non-x86 architectures, handling of loadable modules, compiler optimizations, userspace tooling, patching of data, automated regression testing, and patch-creation guidelines.

Join us for an important and spirited discussion!
