- update to 4.9:
* ISystemtap: the new interactive systemtap jupyter kernel.
This provides a simple GUI for writing/running Systemtap
scripts in an easy, incremental way within Jupyterlab.
Added 2 news scripts, stap-jupyter-install
and stap-jupyter-container. See stap-jupyter(1).
* The new "language-server" mode, specified by "stap
--language-server", starts a LSP server which will
communicate with the client via stdio.
* This server currently supports code completion suggestions.
* See language-server/README.md for more details and usage
instructions.
* Safety/liveness checking for $context variable assignments in
probes of retpoline-compiled kernels is temporarily disabled.
* DWARF-related probes (.function, .statement) now merge DWARF
and non-DWARF symbol-table based matches, rather than being
either-or.
* The python3 tapset was extended to support python3 3.9, 3.10,
and 3.11. See stapprobes(3stap) for further details on probing
python functions.
* A template cve band-aid script is now included, which
demonstrates how to use a new 'livepatch.stp' tapset to
standardize activation, interactive control,
and monitoring of systemtap cve band-aids.
* The kernel runtime now uses much less memory when the number
of "possible CPUs" are way more than the online ones. For
example, VMWare guests usually have 128 "possible CPUs" while fewer
CPUs are actually present or online in the guest system.
* The memory allocation size is now irrelevant to the value of
NR_CPUS of the current kernel. It is only subject to the
