- Upgrade to version 5.1. See systemtap.changes for changelog
- Update to version 5.1
Summary of changes:
* SystemTap frontend (stap) changes
- An experimental "--build-as=USER" flag to reduce privilege during
script compilation, which is a security improvement effort.
- New probe-points for userland hardware breakpoints/watchpoints
targeting processes (PR31180):
probe process.data(ADDRESS).write
probe process.data(ADDRESS).rw
probe process.data(ADDRESS).length(LEN).write
probe process.data(ADDRESS).length(LEN).rw
- Support for stap --remote=bpf.
- Improved searching heuristics for probing symbol names with/without
symbol-version suffixes and with/without weak names.
- Made long-running debuginfod downloads more cleanly interruptible.
- Improved stap-prep heuristics for finding debuginfo for "-rt"
(real-time) kernels.
* SystemTap backend changes
- Dynamic namespace switching for processes targeted via "-x PID",
allowing processes running within containers to be probed.
- Improved message transport robustness for heavy traffic (individual
messages spanning pages) and for short runs (avoiding loss of
last-gasp messages).
- Added MTAG macro on several internal memory allocation routines
to improve leak warnings. Corrected a bunch of leaks.
- "stap -t" now reports module initialization timings too.
- Ported runtime for GCC14 compatibility, with its more recent C
dialect warnings.
- Support for DW_OP_bra in DWARF location lists, which makes a few
more $context variables accessible to systemtap.
* SystemTap tapset changes
- Portability fixes for more recent kernels, as always.
- set_kernel_string* tapset functions improved range checking.
- print_ubacktrace_fileline() works with PIE binaries.
- Many portability improvements and some fixes in the testsuite.
- Enhancements for the tcp, nfs, memory tapsets.

- 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

- Add systemtap-automake112.patch: Fix build with automake 1.12:
+ Support for automatic de-ANSI-fication has been removed.
+ Patch taken from upstream, git commit id 5b2bc70.
Using the upstream patch now.
Note: the patch is >99% useless: Patching configure => it's autogenerated by autoreconf call anyway.
Most projects for this reason don't even carry the generated configure script in their git tree.
