kernel log

1. Please describe the problem:
Since kernel 5.1 sip calls don't work, registration to sip provider fails

2. What is the Version-Release number of the kernel:
5.1.5

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :
Yes in 5.0, problems started with 5.1.5

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
Install kernel 5.1.5 and try to connect to some sip provider or test it:
sipp sip.odorik.cz

When nf_nat_sip is removed by:
modprobe -r nf_nat_sip
sip calls work properly

unfortunately blacklisting the module within /etc/modprobe/blacklist.conf doesn't work for me, module is loaded after restart again

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:
Don't know

6. Are you running any modules that not shipped with directly Fedora's kernel?:
No

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.
Comment 1 Václav Nováček 2019-06-03 08:20:45 UTC 
I have tested the rawhide kernel, but the problem persists...
5.0.17-300.fc30.x86_64 OK
5.1.5-300.fc30.x86_64 SIP KO
5.2.0-0.rc2.git1.2.fc31.x86_64 SIP KO
Comment 2 Václav Nováček 2019-06-03 21:16:55 UTC 
It is an already discovered bug...

Comment 9 Jeremy Cline 2019-06-17 20:42:25 UTC 
Hi Václav,

Did you test kernel-5.1.9 from Fedora? I cherry-picked the fix: https://src.fedoraproject.org/rpms/kernel/c/c0bed758351738c1f970358a32d5793ccfea21c4?branch=f30
Comment 10 Václav Nováček 2019-06-17 20:58:39 UTC 
Hi Jeremy,

no, I did not, I thought that Fedora uses the official kernel from kernel.org.
After installing 5.1.9 from Fedora, UDP works properly.

Thanks a lot and I'm sorry for my confusion.
Comment 11 Jeremy Cline 2019-06-17 21:13:09 UTC 
No worries. Yes, we use very-nearly vanilla kernels, but we do pick up small numbers of patches in cases where it takes a while for a patch to filter back to stable.
