Created attachment 1576505 [details] 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.
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

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
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.
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.
