- Upgrade to version 5.2. See systemtap.changes for changelog
- Upgrade to version 5.2. See systemtap.changes for changelog
- Resolve errors with linux-6.13 based kernels.
Building trivial 'hello world' failed with:
<command-line>: fatal error: {path_to}stapconf.h: No such file or directory
Attemptng to preserve build directory (-k) caused an infinite loop of:
/usr/src/linux-6.13.4-1/scripts/Makefile.build:370: warning: overriding
recipe for target 'modules.order'
New patch: linux-6.13-fedora-compatibility.patch
New patch: rawhide-6.13-kbuild-compatibility.patch
- Update to version 5.2
Summary of changes:
* SystemTap frontend (stap) changes
- New /* pragma:suffix */ for file-level embedded C code blocks to be
placed near the end of the emitted kernel module C file.
Corresponding macros allow additional C hooks for module init/exit.
- With elfutils 0.192's release on 2024-10-18, the "metadata" based
probes announced in systemtap 5.0 should now be increasingly available.
* SystemTap backend changes
- Numerous kernel portability changes
- "probe never" probes don't emit C code at all any more.
- The standard Fedora spec packaging breaks up the sdt.h header file
and the /usr/bin/dtrace stub-builder script, for those cases where
the macros in sdt.h are sufficient.
- More robust message transport draining during shutdown to prevent
message losses.
* SystemTap tapset changes
- Numerous kernel portability changes
- Added a few functions to inet_sock.stp.
* SystemTap sample scripts
- traceio3.stp: Trace VFS operations by filename regex.
- swapmonitor.stp: Trace swap operations.
* Bugfixes
- PR31597 Systemtap not extracting all the data sent to the print data
in the buffers before shutdown
- PR31707 Need a way to postpone emitting the file-level embedded C blocks
- PR31708 Probe never handlers still emit C code for the handler handlers
and probe local structs
- PR31699 UBSAN errors for systemtap map functions with Fedora Rawhide and
Fedora 39 6.8.8 kernels
- PR31740 @hist_log affects the result of @variance
- PR31893 access_ok() was called without turning off page faults
- PR32064 SEC_ERROR_BAD_DATABASE during very first stap-server start
- PR31703 Git detection false positive when 'which' not available
- PR32107 Drop obsolete -Werror hack in buildrun.cxx
- PR32194 Reflect the uprobe_unregister() split
- PR32209 No tracepoints seen using kernel-6.12
- PR32302 Unrecognized tracepoints
- RHEL-55262 Handle S390_lowcore macro removal
- RHEL-66275 Add some inet_sock.stp tapset functions.
- RHEL-66150 Fix cachestat.stp for newer kernels.
- RHEL-66577 Add swapmonitor.stp example script.

DW_AT_comp_dir points to debugsource/linux-obj directory but internal trace
|
|
headers are only found in linux-3.0. Regardless, we don't want to require
|
|
debugsource as devel already requires kernel-source which provides the
|
|
necessary headers.
