This message can be ignored. This bogus "testing the buffer" message is something that inadvertently got into upstream code via commit: 13d0f7b814d9 net/bpfilter: fix dprintf usage for /dev/kmsg
This message is fixed by the following commit: 41c55ea6c2a7 net/bpfilter: remove superfluous testing message The fix will be in the Ubuntu kernel version: Ubuntu- azure-5.3-5.3.0-1023.24 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1879559 Title: net/bpfilter: remove superfluous testing message Status in linux package in Ubuntu: Incomplete Status in linux-hwe-5.0 package in Ubuntu: Confirmed Bug description: [Impact] A testing message was brought by 13d0f7b814d9 ("net/bpfilter: fix dprintf usage for /dev/kmsg") but should've been deleted before patch submission. Although it doesn't cause any harm to the code or functionality itself, it's totally unpleasant to have it displayed on every loop iteration with no real use case. Thus remove it unconditionally. Upstream fix: 41c55ea6c2a7ca4c663eeec05bdf54f4e2419699 [Test Case] Just check dmesg: [ 10.635382] hv_utils: VSS: userspace daemon ver. 129 connected [ 15.306015] bpfilter: Loaded bpfilter_umh pid 1036 [ 15.306280] Started bpfilter [ 15.306283] testing the buffer [ 15.306458] testing the buffer [ 15.306880] testing the buffer [ 15.318003] testing the buffer [ 15.318057] testing the buffer [ 15.318814] testing the buffer [ 15.442147] testing the buffer [ 15.479556] testing the buffer [ 15.479572] testing the buffer [Regression Potential] Very low. The fix is a one line upstream patch that removes one printf.
