Bevor start with ulp, read and understand how live patching is working:

Activating Kernel Live Patching from the command line
SUSEConnect -p sle-module-live-patching/15.4/x86_64 -r LIVE_PATCHING_REGISTRATION_CODE
zypper install -t pattern lp_sles

Performing Kernel Live Patching
zypper se --details kernel-livepatch-*
klp -v patches

Checking expiration date of the live patch
Make sure that the lifecycle-data-sle-module-live-patching is installed, then run the zypper lifecycle command
-

then check https://documentation.suse.com/sles/15-SP4/html/SLES-all/cha-ulp.html

run zypper in libpulp0 libpulp-tools
and install openssl-livepatches packages

to continue with Using libpulp
To enable live patching on an application, we need to preload the libpulp.so.0 library when starting the application, for example:


LD_PRELOAD=/usr/lib64/libpulp.so.0 openssl

and check:

install and configure apache2 with SSL. The reason is that we need a test environment with SSL which is working with apache2 server.

this part is little tricky. In general I had some problems, but now apache2 has been configured with SSL:
Generate a Self-Signed Certificate for apache2:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout sles15sp6.key -out sles15sp6.crt
configure a vhost conf and enable ssl for apache2 then and check that ssl is working

now we need to add in /usr/lib/systemd/system/apache2.service to inject the LD_PRELOAD=libpulp.so:

Environment="LD_PRELOAD=libpulp.so.0"

run systemctl daemon-reload and systemctl restart apache2.service
check apache2 is working

check libpulp.so is loaded:

The recommended way to enable libpulp is to install the libpulp-load-default package.

The Apache process probably has a different version of libcrypto.so loaded, or it's not loaded at all possibly due to vhost configuration. Check this using ulp patches -p $apache_pid.

Also check which libraries are targeted by the livepatch: ulp dump libcrypto_1.1.1l-150400.5.14.0_livepatch2.so

libcryto.so.3.1.4 has been actually loaded

but checked latest patch and it explains why this is not working (assume that older version cannot be applied to newer):

Yes, you need to downgrade libcrypto to the version included in the livepatch filename: e.g. openssl-1.1.1l-150400.7.28.1
Then restart apache and apply livepatch. Each livepatch.so targets a different openssl version so you should install and test all of them, one after another.

Does it make sense to get older libcrypto downgraded on sles15 sp6? I mean all patches of libcrypto.so.1.* and it maybe has target for sles 15 sp5?

It will make sense once SLE-15SP6 starts receiving updates, because openssl RPMs will be supported and livepatched for 12 months after release. It doesn't make sense now because there's nothing to downgrade to, except maybe for switching between openssl1_1 and openssl3 (which IIUC should not be interchangeable as a dependency for Apache and other packages).

The openssl-1_1-livepatches package in SLE-15SP6 pool definitely targets only SLE-15SP4 and SLE-15SP5 openssl so it was likely added to SLE-15SP6 repos by mistake. There are only two openssl packages on SLE-15SP6 right now and neither is targeted by the livepatches:
libopenssl1_1-1.1.1w-150600.2.10
libopenssl3-3.1.4-150600.2.17

okay, thanks for the explanations!
So my bug report is valid. Of course I can check this on sles 15 sp5 for the workflow and learning purpose :)

I have problem with live patches: Build ID mismatch

Which libopenssl version is installed? The openssl-1_1-livepatches package targets only these versions on SLE-15SP5:

libopenssl1_1-1.1.1l-150500.15.4
libopenssl1_1-1.1.1l-150500.17.12.1
libopenssl1_1-1.1.1l-150500.17.15.1
libopenssl1_1-1.1.1l-150500.17.19.1
libopenssl1_1-1.1.1l-150500.17.6.1
libopenssl1_1-1.1.1l-150500.17.9.1

Applying the livepatch .so file to the wrong libopenssl version will result in build ID mismatch error.

Then ulp trigger libcrypto_1.1.1l-150500.15.4.0_livepatch2.so is the only command that will work.

You've tried ulp trigger -p 31678 libcrypto_1.1.1l-150400.5.14.0_livepatch1.so which is the wrong version for another SLES release.
