* selftests: add the missing CONFIG_IP_SCTP in net configXin Long2023-04-131-0/+1

* selftests: net: Test for the IOAM insertion with IPv6Justin Iurman2021-07-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This test evaluates the IOAM insertion for IPv6 by checking the IOAM data integrity on the receiver. The topology is formed by 3 nodes: Alpha (sender), Beta (router in-between) and Gamma (receiver). An IOAM domain is configured from Alpha to Gamma only, which means not on the reverse path. When Gamma is the destination, Alpha adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop and fills the trace with its own IOAM data. Beta and Gamma also fill the trace. The IOAM data integrity is checked on Gamma, by comparing with the pre-defined IOAM configuration (see below). +-------------------+ +-------------------+ | | | | | alpha netns | | gamma netns | | | | | | +-------------+ | | +-------------+ | | | veth0 | | | | veth0 | | | | db01::2/64 | | | | db02::2/64 | | | +-------------+ | | +-------------+ | | . | | . | +-------------------+ +-------------------+ . . . . . . +----------------------------------------------------+ | . . | | +-------------+ +-------------+ | | | veth0 | | veth1 | | | | db01::1/64 | ................ | db02::1/64 | | | +-------------+ +-------------+ | | | | beta netns | | | +--------------------------+-------------------------+ ~~~~~~~~~~~~~~~~~~~~~~ | IOAM configuration | ~~~~~~~~~~~~~~~~~~~~~~ Alpha +-----------------------------------------------------------+ | Type | Value | +-----------------------------------------------------------+ | Node ID | 1 | +-----------------------------------------------------------+ | Node Wide ID | 11111111 | +-----------------------------------------------------------+ | Ingress ID | 0xffff (default value) | +-----------------------------------------------------------+ | Ingress Wide ID | 0xffffffff (default value) | +-----------------------------------------------------------+ | Egress ID | 101 | +-----------------------------------------------------------+ | Egress Wide ID | 101101 | +-----------------------------------------------------------+ | Namespace Data | 0xdeadbee0 | +-----------------------------------------------------------+ | Namespace Wide Data | 0xcafec0caf00dc0de | +-----------------------------------------------------------+ | Schema ID | 777 | +-----------------------------------------------------------+ | Schema Data | something that will be 4n-aligned | +-----------------------------------------------------------+ Note: When Gamma is the destination, Alpha adds an IOAM Pre-allocated Trace option inside a Hop-by-hop, where 164 bytes are pre-allocated for the trace, with 123 as the IOAM-Namespace and with 0xfff00200 as the trace type (= all available options at this time). As a result, and based on IOAM configurations here, only both Alpha and Beta should be capable of inserting their IOAM data while Gamma won't have enough space and will set the overflow bit.

* | selftests/net: SO_TXTIME with ETF and FQWillem de Bruijn2019-05-241-0/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SO_TXTIME API enables packet tranmission with delayed delivery. This is currently supported by the ETF and FQ packet schedulers. Evaluate the interface with both schedulers. Install the scheduler and send a variety of packets streams: without delay, with one delayed packet, with multiple ordered delays and with reordering. Verify that packets are released by the scheduler in expected order. The ETF qdisc requires a timestamp in the future on every packet. It needs a delay on the qdisc else the packet is dropped on dequeue for having a delivery time in the past. The test value is experimentally derived. ETF requires clock_id CLOCK_TAI. It checks this base and drops for non-conformance. The FQ qdisc expects clock_id CLOCK_MONOTONIC, the base used by TCP as of commit fb420d5d91c1 ("tcp/fq: move back to CLOCK_MONOTONIC"). Within a flow there is an expecation of ordered delivery, as shown by delivery times of test 4. The FQ qdisc does not require all packets to have timestamps and does not drop for non-conformance. The large (msec) delays are chosen to avoid flakiness. Output: SO_TXTIME ipv6 clock monotonic payload:a delay:28 expected:0 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:38 expected:0 (us) SO_TXTIME ipv6 clock monotonic payload:a delay:40 expected:0 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:33 expected:0 (us) SO_TXTIME ipv6 clock monotonic payload:a delay:10120 expected:10000 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:10102 expected:10000 (us) [.. etc ..] OK.

Also changes: ret = nf_nat_ipv4_fn(priv, skb, state); if (ret != NF_DROP && ret != NF_STOLEN && into if (ret != NF_ACCEPT) return ret; everywhere. The nat hooks never should return anything other than ACCEPT or DROP (and the latter only in rare error cases). The original code uses multi-line ANDing including assignment-in-if: if (ret != NF_DROP && ret != NF_STOLEN && !(IPCB(skb)->flags & IPSKB_XFRM_TRANSFORMED) && (ct = nf_ct_get(skb, &ctinfo)) != NULL) { I removed this while moving, breaking those in separate conditionals and moving the assignments into extra lines. checkpatch still generates some warnings: 1. Overly long lines (of moved code). Breaking them is even more ugly. so I kept this as-is. 2. use of extern function declarations in a .c file. This is necessary evil, we must call nf_nat_l3proto_register() from the nat core now. All l3proto related functions are removed later in this series, those prototypes are then removed as well. v2: keep empty nf_nat_ipv6_csum_update stub for CONFIG_IPV6=n case. v3: remove IS_ENABLED(NF_NAT_IPV4/6) tests, NF_NAT_IPVx toggles are removed here. v4: also get rid of the assignments in conditionals.
