Florian Westphal says: ==================== net: fix netfilter defrag/ip tunnel pmtu blackhole Christian Perle reported a PMTU blackhole due to unexpected interaction between the ip defragmentation that comes with connection tracking and ip tunnels. Unfortunately setting 'nopmtudisc' on the tunnel breaks the test scenario even without netfilter. Christinas setup looks like this: +--------+ +---------+ +--------+ |Router A|-------|Wanrouter|-------|Router B| | |.IPIP..| |..IPIP.| | +--------+ +---------+ +--------+ / mtu 1400 \ / \ +--------+ +--------+ |Client A| |Client B| +--------+ +--------+ MTU is 1500 everywhere, except on Router A to Wanrouter and Wanrouter to Router B. Router A and Router B use IPIP tunnel interfaces to tunnel traffic between Client A and Client B over WAN. Client A sends a 1400 byte UDP datagram to Client B. This packet gets encapsulated in the IPIP tunnel. This works, packet is received on client B. When conntrack (or anything else that forces ip defragmentation) is enabled on Router A, the packet gets dropped on Router A after encapsulation because they exceed the link MTU. Setting the 'nopmtudisc' flag on the IPIP tunnel makes things worse, no packets pass even in the no-netfilter scenario. Patch one is a reproducer script for selftest infra. Patch two is a fix for 'nopmtudisc' behaviour so ip_tunnel will send an icmp error to Client A. This allows 'nopmtudisc' tunnel to forward the UDP datagrams. Patch three enables ip refragmentation for all reassembled packets, just like ipv6. ==================== Link: https://lore.kernel.org/r/20210105231523.622-1-fw@strlen.deSigned-off-by: -

Conntrack reassembly records the largest fragment size seen in IPCB. However, when this gets forwarded/transmitted, fragmentation will only be forced if one of the fragmented packets had the DF bit set. In that case, a flag in IPCB will force fragmentation even if the MTU is large enough. This should work fine, but this breaks with ip tunnels. Consider client that sends a UDP datagram of size X to another host. The client fragments the datagram, so two packets, of size y and z, are sent. DF bit is not set on any of these packets. Middlebox netfilter reassembles those packets back to single size-X packet, before routing decision. packet-size-vs-mtu checks in ip_forward are irrelevant, because DF bit isn't set. At output time, ip refragmentation is skipped as well because x is still smaller than the mtu of the output device. If ttransmit device is an ip tunnel, the packet size increases to x+overhead. Also, tunnel might be configured to force DF bit on outer header. In this case, packet will be dropped (exceeds MTU) and an ICMP error is generated back to sender. But sender already respects the announced MTU, all the packets that it sent did fit the announced mtu. Force refragmentation as per original sizes unconditionally so ip tunnel will encapsulate the fragments instead. The only other solution I see is to place ip refragmentation in the ip_tunnel code to handle this case. Fixes: d6b915e2 ("ip_fragment: don't forward defragmented DF packet") Reported-by:

Florian Westphal authored
For some reason ip_tunnel insist on setting the DF bit anyway when the inner header has the DF bit set, EVEN if the tunnel was configured with 'nopmtudisc'. This means that the script added in the previous commit cannot be made to work by adding the 'nopmtudisc' flag to the ip tunnel configuration. Doing so breaks connectivity even for the without-conntrack/netfilter scenario. When nopmtudisc is set, the tunnel will skip the mtu check, so no icmp error is sent to client. Then, because inner header has DF set, the outer header gets added with DF bit set as well. IP stack then sends an error to itself because the packet exceeds the device MTU.

Adds new 2 new tests to the PTMU script: pmtu_ipv4/6_route_change. These tests explicitly test for a recently discovered problem in the IPv6 routing framework where PMTU exceptions were not properly released when replacing a route via "ip route change ...". After creating PMTU exceptions, the route from the device A to R1 will be replaced with a new route, then device A will be deleted. If the PMTU exceptions were properly cleaned up by the kernel, this device deletion will succeed. Otherwise, the unregistration of the device will stall, and messages such as the following will be logged in dmesg: unregister_netdevice: waiting for veth_A-R1 to become free.

Route removal is handled by two code paths. The main removal path is via fib6_del_route() which will handle purging any PMTU exceptions from the cache, removing all per-cpu copies of the DST entry used by the route, and releasing the fib6_info struct. The second removal location is during fib6_add_rt2node() during a route replacement operation. This path also calls fib6_purge_rt() to handle cleaning up the per-cpu copies of the DST entries and releasing the fib6_info associated with the older route, but it does not flush any PMTU exceptions that the older route had. Since the older route is removed from the tree during the replacement, we lose any way of accessing it again. As these lingering DSTs and the fib6_info struct are holding references to the underlying netdevice struct as well, unregistering that device from the kernel can never complete.

The previous patch fixes a TEF vs. TX race condition, by first updating the TEF tail pointer in hardware, and then updating the driver internal pointer. The same pattern exists in the RX-path, too. This should be no problem, as the driver accesses the RX-FIFO from the interrupt handler only, thus the access is properly serialized. Fix the order here, too, so that the TEF- and RX-path look similar.

The mcp251xfd driver uses a TX FIFO for sending CAN frames and a TX Event FIFO (TEF) for completed TX-requests. The TEF event handling in the mcp251xfd_handle_tefif() function has a race condition. It first increments the tx-ring's tail counter to signal that there's room in the TX and TEF FIFO, then it increments the TEF FIFO in hardware. A running mcp251xfd_start_xmit() on a different CPU might not stop the txqueue (as the tx-ring still shows free space). The next mcp251xfd_start_xmit() will push a message into the chip and the TX complete event might overflow the TEF FIFO. This patch changes the order to fix the problem.

Aligning to tx_ndp_modulus is not sufficient because the next align call can be cdc_ncm_align_tail, which can add up to ctx->tx_modulus + ctx->tx_remainder - 1 bytes. This used to lead to occasional crashes on a Huawei 909s-120 LTE module as follows: - the condition marked /* if there is a remaining skb [...] */ is true so the swaps happen - skb_out is set from ctx->tx_curr_skb - skb_out->len is exactly 0x3f52 - ctx->tx_curr_size is 0x4000 and delayed_ndp_size is 0xac (note that the sum of skb_out->len and delayed_ndp_size is 0x3ffe) - the for loop over n is executed once - the cdc_ncm_align_tail call marked /* align beginning of next frame */ increases skb_out->len to 0x3f56 (the sum is now 0x4002) - the condition marked /* check if we had enough room left [...] */ is false so we break out of the loop - the condition marked /* If requested, put NDP at end of frame. */ is true so the NDP is written into skb_out - now skb_out->len is 0x4002, so padding_count is minus two interpreted as an unsigned number, which is used as the length argument to memset, leading to a crash with various symptoms but usually including > Call Trace: > <IRQ> > cdc_ncm_fill_tx_frame+0x83a/0x970 [cdc_ncm] > cdc_mbim_tx_fixup+0x1d9/0x240 [cdc_mbim] > usbnet_start_xmit+0x5d/0x720 [usbnet] The cdc_ncm_align_tail call first aligns on a ctx->tx_modulus boundary (adding at most ctx->tx_modulus-1 bytes), then adds ctx->tx_remainder bytes.

A similar problem has occurred before, and the code is nontrivial to reason about, so add a guard before the crashing call. By that time it is too late to prevent any memory corruption (we'll have written past the end of the buffer already) but we can at least try to get a warning written into an on-disk log by avoiding the hard crash caused by padding past the buffer with a huge number of zeros.

As a result, the driver unset the syscon value in sun8i_dwmac_exit, but this leaves it uninitialized after a suspend/ resume cycle. It was also unset a second time (outside sun8i_dwmac_exit) in the probe error path. Move the init to the earliest available place in sun8i_dwmac_probe (after stmmac_probe_config_dt, which initializes plat_dat), and the deinit to the corresponding position in the cleanup order. Since priv is not filled in until stmmac_dvr_probe, this requires changing the sun8i_dwmac_set_syscon parameters to priv's two relevant members.

sun8i_dwmac_exit calls sun8i_dwmac_unpower_internal_phy, but sun8i_dwmac_init did not call sun8i_dwmac_power_internal_phy. This caused PHY power to remain off after a suspend/resume cycle. Fix this by recording if PHY power should be restored, and if so, restoring it. Fixes: 634db83b ("net: stmmac: dwmac-sun8i: Handle integrated/external MDIOs") Signed-off-by:
