https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240023 Bug ID: 240023 Summary: netmap lb pointer out of bounds on ixgbe Product: Base System Version: 11.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: maware@ucsc.edu when using the lb utility for packet flows the rings appear to go out of bounds. System is using a 82599 based Intel adapter (ixgbe). tried with both bro 2.6.3 and bro 2.6.2. Netmap plugin tried from zkg and built from source. This problem does not exist in 11.2 p9. This may be related to driver changes ~april 2019 for ixgbe. When this issue happens lb stops reporting any incrementing of packet counters. Command issues to start lb: lb -i ix2 -p 20 -o 30 042.269723 [1721] nm_rxsync_prologue ix2 RX13: fail 'head < kring->nr_hwcur || head > kring->nr_hwtail' h 1442 c 1442 t 1443 rh 1442 rc 1442 rt 1443 hc 1443 ht 1443 042.269754 [1766] netmap_ring_reinit called for ix2 RX13 042.282035 [1721] nm_rxsync_prologue ix2 RX13: fail 'head < kring->nr_hwcur || head > kring->nr_hwtail' h 1826 c 1826 t 1827 rh 1826 rc 1826 rt 1827 hc 1827 ht 1827 042.282065 [1766] netmap_ring_reinit called for ix2 RX13 042.286129 [1721] nm_rxsync_prologue ix2 RX8: fail 'head < kring->nr_hwcur || head > kring->nr_hwtail' h 2801 c 2801 t 2804 rh 2801 rc 2801 rt 2804 hc 2804 ht 2804 042.286155 [1766] netmap_ring_reinit called for ix2 RX8 042.301701 [1721] nm_rxsync_prologue ix2 RX5: fail 'head < kring->nr_hwcur || head > kring->nr_hwtail' h 3990 c 3990 t 3988 rh 3990 rc 3990 rt 3988 hc 3987 ht 3988 042.301729 [1766] netmap_ring_reinit called for ix2 RX5 042.304510 [1721] nm_rxsync_prologue ix2 RX11: fail 'head < kring->nr_hwcur || head > kring->nr_hwtail' h 302 c 302 t 304 rh 302 rc 302 rt 304 hc 304 ht 304 042.304533 [1766] netmap_ring_reinit called for ix2 RX11 042.304558 [1766] netmap_ring_reinit called for ix2 RX15 042.307984 [1766] netmap_ring_reinit called for ix2 RX6 042.308521 [1766] netmap_ring_reinit called for ix2 RX7 042.313627 [1766] netmap_ring_reinit called for ix2 RX6 042.314349 [1766] netmap_ring_reinit called for ix2 RX1 042.317253 [1723] nm_rxsync_prologue ix2 RX5: fail 'cur < head || cur > kring->nr_hwtail' h 273 c 272 t 273 rh 273 rc 272 rt 273 hc 272 ht 273 042.319884 [1726] nm_rxsync_prologue ix2 RX4: fail 'head < kring->nr_hwcur && head > kring->nr_hwtail' h 4094 c 4094 t 2 rh 4094 rc 4094 rt 2 hc 4095 ht 2 042.321352 [1723] nm_rxsync_prologue ix2 RX10: fail 'cur < head || cur > kring->nr_hwtail' h 432 c 431 t 432 rh 432 rc 431 rt 432 hc 431 ht 432 042.321993 [1723] nm_rxsync_prologue ix2 RX1: fail 'cur < head || cur > kring->nr_hwtail' h 3751 c 3750 t 3751 rh 3751 rc 3750 rt 3751 hc 3750 ht 3751 042.360195 [1723] nm_rxsync_prologue ix2 RX2: fail 'cur < head || cur > kring->nr_hwtail' h 2678 c 2677 t 2678 rh 2678 rc 2677 rt 2678 hc 2677 ht 2678 042.380046 [1723] nm_rxsync_prologue ix2 RX6: fail 'cur < head || cur > kring->nr_hwtail' h 3787 c 3786 t 3787 rh 3787 rc 3786 rt 3787 hc 3786 ht 3787 -- You are receiving this mail because: You are the assignee for the bug.home | help
