https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=295016 Bug ID: 295016 Summary: [bpf] pflogd in endless loop on VMs Product: Base System Version: 15.1-STABLE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: thierry.dussuet@protonmail.com FreeBSD pte.glloq 15.1-PRERELEASE FreeBSD 15.1-PRERELEASE stable/15-n283066-9331e62e8b80 GENERIC amd64 Since the last update on 15/stable, pflogd does an endless loop: select(4,{ 3 },0x0,0x0,{ 0.500000 }) = 1 (0x1) ioctl(3,BIOCROTZBUF,0xba59e52f148) = 0 (0x0) clock_gettime(4,{ 422280.870589888 }) = 0 (0x0) select(4,{ 3 },0x0,0x0,{ 0.500000 }) = 1 (0x1) ioctl(3,BIOCROTZBUF,0xba59e52f148) = 0 (0x0) clock_gettime(4,{ 422280.870724791 }) = 0 (0x0) select(4,{ 3 },0x0,0x0,{ 0.500000 }) = 1 (0x1) ioctl(3,BIOCROTZBUF,0xba59e52f148) = 0 (0x0) clock_gettime(4,{ 422280.870890490 }) = 0 (0x0) select(4,{ 3 },0x0,0x0,{ 0.500000 }) = 1 (0x1) ioctl(3,BIOCROTZBUF,0xba59e52f148) = 0 (0x0) clock_gettime(4,{ 422280.871082318 }) = 0 (0x0) This has happened only on rented virtual machines so far, both amd64 amd arm64. Changing the sysctl net.bpf.zerocopy_enable does not seem to make any difference, weirdly enough. Any idea on what to try? -- You are receiving this mail because: You are the assignee for the bug.home | help
