While stress testing MTU probing, we had crashes in list_del() that we root-caused to the fact that tcp_fragment() is unconditionally inserting the freshly allocated skb into tsorted_sent_queue list. But this list is supposed to contain skbs that were sent. This was mostly harmless until MTU probing was enabled. Fortunately we can use the tcp_queue enum added later (but in same linux version) for rtx-rb-tree to fix the bug.

The neighbor monitor employs a threshold, default set to 32 peer nodes, where it activates the "Overlapping Neighbor Monitoring" algorithm. Below that threshold, monitoring is full-mesh, and no "domain records" are passed between the nodes. Because of this, a node never received a peer's ack that it has received the most recent update of the own domain. Hence, the field 'acked_gen' in struct tipc_monitor_state remains permamently at zero, whereas the own domain generation is incremented for each added or removed peer. This has the effect that the function tipc_mon_get_state() always sets the field 'probing' in struct tipc_monitor_state true, again leading the tipc_link_timeout() of the link in question to always send out a probe, even when link->silent_intv_count is zero. This is functionally harmless, but leads to some unncessary probing, which can easily be eliminated by setting the 'probing' field of the said struct correctly in such cases. At the same time, we explictly invalidate the sent domain records when the algorithm is not activated. This will eliminate any risk that an invalid domain record might be inadverently accepted by the peer. Signed-off-by:

Up until now we used the hardware's defaults for multipath hash computation. This patch aligns the hardware's multipath parameters with the kernel's. For IPv4 packets, the parameters are determined according to the 'fib_multipath_hash_policy' sysctl during module initialization. In case L3-mode is requested, only the source and destination IP addresses are used. There is no special handling of ICMP error packets. In case L4-mode is requested, a 5-tuple is used: source and destination IP addresses, source and destination ports and IP protocol. Note that the layer 4 fields are not considered for fragmented packets. For IPv6 packets, the source and destination IP addresses are used, as well as the flow label and the next header fields.

RFC 8200 (IPv6) defines Hop-by-Hop options and Destination options extension headers. Both of these carry a list of TLVs which is only limited by the maximum length of the extension header (2048 bytes). By the spec a host must process all the TLVs in these options, however these could be used as a fairly obvious denial of service attack. I think this could in fact be a significant DOS vector on the Internet, one mitigating factor might be that many FWs drop all packets with EH (and obviously this is only IPv6) so an Internet wide attack might not be so effective (yet!). By my calculation, the worse case packet with TLVs in a standard 1500 byte MTU packet that would be processed by the stack contains 1282 invidual TLVs (including pad TLVS) or 724 two byte TLVs. I wrote a quick test program that floods a whole bunch of these packets to a host and sure enough there is substantial time spent in ip6_parse_tlv. These packets contain nothing but unknown TLVS (that are ignored), TLV padding, and bogus UDP header with zero payload length. 25.38% [kernel] [k] __fib6_clean_all 21.63% [kernel] [k] ip6_parse_tlv 4.21% [kernel] [k] __local_bh_enable_ip 2.18% [kernel] [k] ip6_pol_route.isra.39 1.98% [kernel] [k] fib6_walk_continue 1.88% [kernel] [k] _raw_write_lock_bh 1.65% [kernel] [k] dst_release This patch adds configurable limits to Destination and Hop-by-Hop options. There are three limits that may be set: - Limit the number of options in a Hop-by-Hop or Destination options extension header. - Limit the byte length of a Hop-by-Hop or Destination options extension header. - Disallow unrecognized options in a Hop-by-Hop or Destination options extension header. The limits are set in corresponding sysctls: ipv6.sysctl.max_dst_opts_cnt ipv6.sysctl.max_hbh_opts_cnt ipv6.sysctl.max_dst_opts_len ipv6.sysctl.max_hbh_opts_len If a max_*_opts_cnt is less than zero then unknown TLVs are disallowed. The number of known TLVs that are allowed is the absolute value of this number. If a limit is exceeded when processing an extension header the packet is dropped. Default values are set to 8 for options counts, and set to INT_MAX for maximum length. Note the choice to limit options to 8 is an arbitrary guess (roughly based on the fact that the stack supports three HBH options and just one destination option). These limits have being proposed in draft-ietf-6man-rfc6434-bis. Tested (by Martin Lau) I tested out 1 thread (i.e. one raw_udp process). I changed the net.ipv6.max_dst_(opts|hbh)_number between 8 to 2048. With sysctls setting to 2048, the softirq% is packed to 100%. With 8, the softirq% is almost unnoticable from mpstat. v2; - Code and documention cleanup. - Change references of RFC2460 to be RFC8200. - Add reference to RFC6434-bis where the limits will be in standard.

There is no necessary to reallocate the descriptor and remap the descriptor memory in reset process, But there is still some other action exist in both reset process and initialization process. To reuse the common interface in reset process and initialization process, This patch moves out the descriptor allocate and memory maping from interface cmdq_init. Signed-off-by:

It needs initialize mdio in initialization process, but reset process does not reset mdio, so do not initialize mdio in reset process. This patch move out the mdio configuration function from the mac_init. So mac_init can be used both in reset process and initialization process. Signed-off-by:

One of the timer conversion patches evidently escaped build testing until I ran into in on ARM randconfig builds: drivers/net/ethernet/seeq/ether3.c: In function 'ether3_ledoff': drivers/net/ethernet/seeq/ether3.c:175:40: error: 'priv' undeclared (first use in this function); did you mean 'pid'? drivers/net/ethernet/seeq/ether3.c:176:27: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] This fixes the two small typos that caused the problems. Fixes: 6fd9c53f ("net: seeq: Convert timers to use timer_setup()") Signed-off-by:
