If the problem is solved, change the tag 'verification-needed-precise' to 'verification-done-precise'. If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

[Bug 669641] Re: systemtap fails to discover installed debug modules
** Description changed:
+ == Precise SRU Justification ==
+
+ Impact: When using systemtap with Ubuntu kernels, the proper debug
+ modules cannot be automatically discovered.
+
+ == Fix ==
+
+ This fix allows for the build system to insert the .gnu_debuglink
+ sections in the .ko files pointing to the full unstripped .ko in
+ /usr/lib/debug/.. in the dbgsym ddebs. In addition there are checks to
+ ensure the debug symbol actually exists before creating the
+ .gnu_debuglink section.
+
+ == Testcase ==
+
+ 1) Install systemtap.
+ 2) Run stap -l 'module(serio_raw).function(*)'
+ 3) This should show list all the probe points for that module.
+
+ --
+
Binary package hint: systemtap
Even if the proper debug symbols are installed:
# stap -l 'kernel.function(acpi_*)' | sort
will succeed
and this will fail.
# stap -l 'module(ohci1394).function(*)' | sort
Now there's no shortage of blogs and wikis on how to work
around this but no one has seemingly ever investigated the root
cause. If one were to run this through strace you would find
the following.
open(/usr/lib/debug/.build-id/3b/6eb5a0f22ba2bc92c3c3f1fcb14fe7f31f3807.debug,
O_RDONLY) = -1 ENOENT (No such file or directory)
open(/lib/modules/2.6.32-25-generic/kernel/drivers/ieee1394/ohci1394.ko.debug,
O_RDONLY) = -1 ENOENT (No such file or directory)
open(/lib/modules/2.6.32-25-generic/kernel/drivers/ieee1394/.debug/ohci1394.ko.debug,
O_RDONLY) = -1 ENOENT (No such file or directory)
open(/usr/lib/debug/lib/modules/2.6.32-25-generic/kernel/drivers/ieee1394/ohci1394.ko.debug,
O_RDONLY) = -1 ENOENT (No such file or directory)
open(/lib/modules/2.6.32-25-generic/kernel/drivers/ieee1394/build/ohci1394.ko.debug,
O_RDONLY) = -1 ENOENT (No such file or directory)
Note that the path is correct, it's the name of the KO that stap is expecting
that is wrong,
Kernel debug symbols provided by Ubuntu are unstripped yet maintain the .ko
extension,
systemtap (actually libelf/elfutils) is expecting the filename to be
module.ko.debug.
After discussing this on #systemtap on Freenode, the following script was
proposed to
generate a symlink tree, by build id, in /usr/lib/debug, with the proper
extension. This
completely solves the issue, and is also of benefit to things like gdb and
oprofile.
#!/bin/sh
for file in `find /usr/lib/debug -name '*.ko' -print`
do
- buildid=`eu-readelf -n $file| grep Build.ID: | awk '{print $3}'`
- dir=`echo $buildid | cut -c1-2`
- fn=`echo $buildid | cut -c3-`
- mkdir -p /usr/lib/debug/.build-id/$dir
- ln -s $file /usr/lib/debug/.build-id/$dir/$fn
- ln -s $file /usr/lib/debug/.build-id/$dir/${fn}.debug
+ buildid=`eu-readelf -n $file| grep Build.ID: | awk '{print $3}'`
+ dir=`echo $buildid | cut -c1-2`
+ fn=`echo $buildid | cut -c3-`
+ mkdir -p /usr/lib/debug/.build-id/$dir
+ ln -s $file /usr/lib/debug/.build-id/$dir/$fn
+ ln -s $file /usr/lib/debug/.build-id/$dir/${fn}.debug
done
If we could integrate this into the ddeb postinstall script, the problem would
be solved.

[Bug 669641] Re: systemtap fails to discover installed debug modules
The root cause of the build failure under precise was that we were trying to assign an entry to debuglink that didn't exist. When the build was iterating over kos, it simply expects that the path in /lib/modules will mirror that found in /usr/lib/debug, this is not always true. There are modules copied to places like /lib/modules/3.2.0-25-generic/initrd/, of which there exists no analog under the current debug tree structure, nor should there as it's a copy of a perfectly probable module already found in kernel/ This updated v2 patches checks that the destination debug ko exists before attempt to update the gnu_debuglink section. It's also noteworthy that objcopy isn't just recording a pathname into that space, it's reading the unstripped ko. I've tested this patch extensively on precise, including developer builds where I delete the build stamp, change the source code for a single module and incrementally rebuild the entire package. The dbgsyms remain consistent. ** Patch added: 0001-UBUNTU-PACKAGING-v2-add-.gnu_debuglink-sections-to-..patch https://bugs.launchpad.net/ubuntu/+source/systemtap/+bug/669641/+attachment/3199263/+files/0001-UBUNTU-PACKAGING-v2-add-.gnu_debuglink-sections-to-..patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/669641 Title: systemtap fails to discover installed debug modules To manage notifications about this bug go to: https://bugs.launchpad.net/linaro-ubuntu/+bug/669641/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 669641] Re: systemtap fails to discover installed debug modules
Building against precise is interesting, at first we thought (ayan and myself)
that
we were modifying the same object twice which results in an error. To remedy
that, sort -u was added to the processing loop. After another precise build
with that precaution we get this failure.

@Chris, this doesn't work. BTW, you don't have to bounce this back to me to verify, this is a one line test, either the probed module will return a list of entry points, or it won't.

OK, so I think you have a build issue, as I can add the run the objcopy

But strace confirms that the debug file was opened

munmap(0x7faaa4333000, 689768) = 0
close(4)= 0
close(4)= -1 EBADF (Bad file descriptor)
So what went wrong? When I go back and apply the script that
creates the shadow links to the debug files the result is the same, no
output, regardless of the module I choose to test.
I think your build is broken.
