Hi= .

We got a freebsd router with both ospf/bpg and multipath rou= tes (ECMP) (using the new bird2 with netlink) .

The router g= ot an interface with carp enabled on it (gateway for admin vlan).

Packets received on the carp address gets r= outed on all known routes towards destination. Thus, the destination host receives duplicates ip packets. (which disrupts most udp based protocols)

Using a simple alias instead of carp solve the problem. Is this= a known problem, or should I fill a PR ?

No= , that=E2=80=99s not a known problem. 
Please do open= the PR with details.

Hi.

We got a freebsd router with both ospf/bpg and multipath routes (ECMP) (using the new bird2 with netlink) .

The router got an interface with carp enabled on it (gateway for admin vlan).

Packets received on the carp address gets routed on all known routes towards destination. Thus, the destination host receives duplicates ip packets. (which disrupts most udp based protocols)

Using a simple alias instead of carp solve the problem. Is this a known problem, or should I fill a PR ?

No, that’s not a known problem. 
Please do open the PR with details.

RFC 5681 also requires that a receiver SHOULD generate an ACK for at least every second full-sized segment, so bytes_acked per ACK is at most 2 * SMSS. If both sender and receiver follow it. cwnd should grow exponentially during slow-slow: cwnd *= 2 (per RTT) However, LRO and TSO are widely used today, so receiver may generate much less ACKs than it used to do. As I observed, Both FreeBSD and Linux generates at most one ACK per segment assembled by LRO/GRO. The worst case is one ACK per 45 MSS, as 45 * 1448 = 65160 < 65535. Sending 1MB over a link of 100ms delay from FreeBSD 13.2: 0.000 IP sender > sink: Flags [S], seq 205083268, win 65535, options [mss 1460,nop,wscale 10,sackOK,TS val 495212525 ecr 0], length 0 0.100 IP sink > sender: Flags [S.], seq 708257395, ack 205083269, win 65160, options [mss 1460,sackOK,TS val 563185696 ecr 495212525,nop,wscale 7], length 0 0.100 IP sender > sink: Flags [.], ack 1, win 65, options [nop,nop,TS val 495212626 ecr 563185696], length 0 // TSopt omitted below for brevity. // cwnd = 10 * MSS, sent 10 * MSS 0.101 IP sender > sink: Flags [.], seq 1:14481, ack 1, win 65, length 14480 // got one ACK for 10 * MSS, cwnd += 2 * MSS, sent 12 * MSS 0.201 IP sink > sender: Flags [.], ack 14481, win 427, length 0 0.201 IP sender > sink: Flags [.], seq 14481:31857, ack 1, win 65, length 17376 // got ACK of 12*MSS above, cwnd += 2 * MSS, sent 14 * MSS 0.301 IP sink > sender: Flags [.], ack 31857, win 411, length 0 0.301 IP sender > sink: Flags [.], seq 31857:52129, ack 1, win 65, length 20272 // got ACK of 14*MSS above, cwnd += 2 * MSS, sent 16 * MSS 0.402 IP sink > sender: Flags [.], ack 52129, win 395, length 0 0.402 IP sender > sink: Flags [P.], seq 52129:73629, ack 1, win 65, length 21500 0.402 IP sender > sink: Flags [.], seq 73629:75077, ack 1, win 65, length 1448 As a consequence, instead of growing exponentially, cwnd grows more-or-less quadratically during slow-start, unless abc_l_var is set to a sufficiently large value. NewReno took more than 20 seconds to ramp up throughput to 100Mbps over an emulated 100ms delay link. While Linux took ~2 seconds. I can provide the pcap file if anyone is interested. Switching to CUBIC won't help, because it uses the logic in NewReno ack_received() for slow start. Is this a well-known issue and abc_l_var is the only cure for it? https://calomel.org/freebsd_network_tuning.html Thank you!

The "nsegs" are passed along like this: nsegs = max(1, m->m_pkthdr.lro_nsegs); ... cc_ack_received(tp, th, nsegs, CC_ACK); ... (Newreno - FreeBSD-14) incr = min(ccv->bytes_this_ack, ccv->nsegs * abc_val * CCV(ccv, t_maxseg)); And in FreeBSD-10 being mentioned in your article: (Newreno - FreeBSD-10) incr = min(ccv->bytes_this_ack, V_tcp_abc_l_var * CCV(ccv, t_maxseg)); There is no such thing.

Hi Randall, Thanks for your information, I didn't know that middle boxes can do such th= ings. Linux effectively sets abc_l_var to +inf, and opens cwnd quicker for aggregated ACKs. Its receiver also enters "quickack" mode after establishing a link to "accelerate slow-start". So its cwnd grows much more aggressively. My puzzle has been solved.

If I load if from /boot/loader.conf, or from kld_list = in /etc/rc.conf, then it works fine. But if I load it by hand with "kldload if_bnxt" after booting has completed, then I get the same "iflib_dma_alloc_align: bus_dma_tag_create failed: 22" error that others report, and no bnxt devices are created. However, if I then unload the mod= ule and load it again, it works on the second try. I cannot reproduce the problem on 14.0-CURRENT simply because on that versi= on, something causes the module to load automatically. And I can't unload the module to try again due to bug #270270. My firmware is: dev.bnxt.0.ver.roce_fw: 214.0.194 dev.bnxt.0.ver.netctrl_fw: 214.4.7 dev.bnxt.0.ver.mgmt_fw: 214.4.42 dev.bnxt.0.ver.hwrm_fw: 214.4.91 --=20 You are receiving this mail because: You are the assignee for the bug.
