This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed- xenial'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you! ** Tags added: verification-needed-xenial -- 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/1765698 Title: Unable to insert test_bpf module on Xenial Status in linux package in Ubuntu: Incomplete Status in linux source package in Xenial: Fix Committed Bug description: [SRU Justification] Impact: One of the self-tests which is run by test_bpf will always fail when JIT is turned on, causing the module load to fail. Fix: Picking two patches from upstream will fix this. Testcase: sudo modprobe test_bpf Risk of regression: Minimal, this modifies only a test module, no impact on normal operation. --- With 4.4.0-119, the ubuntu_bpf_jit test will pass: [ 127.177037] test_bpf: Summary: 291 PASSED, 0 FAILED, [0/283 JIT'ed] PASSED: 291 FAILED: 0 But with 4.4.0-121, one test will fail [ 221.361834] test_bpf: Summary: 290 PASSED, 1 FAILED, [282/282 JIT'ed] PASSED: 290 FAILED: 1 stderr: modprobe: ERROR: could not insert 'test_bpf': Invalid argument $ sudo modprobe test_bpf modprobe: ERROR: could not insert 'test_bpf': Invalid argument $ dmesg|grep test_bpf|grep FAIL [ 45.286944] test_bpf: #248 BPF_MAXINSNS: Jump, gap, jump, ...
