2020-09-01ip: fix ip zero checksum verificationBenoît Ganne1-1/+1
In one's complement, there are two representations of zero: the all zero and the all one bit values, often referred to as +0 and -0. See RFC 1624 section 3 for more details. This used to be taken care of in ip4_header_checksum(), but it is no longer the case. The check ip->checksum == ip4_header_checksum (ip) is no longer correct in the -0 case. Always use ip4_header_checksum_is_valid() instead (which behaves correctly since 9a79a1ab931c3b5a7ae07d6f0fcfef7c4368a2c4).

2020-05-27nat: fix regarding vm arg for vlib_time_now callElias Rudberg1-1/+2
Change in snat_ipfix_header_create() to use thread-specific vlib_main_t *vm pointer to avoid problems with different threads accessing the same vlib_main_t data structure. This avoids assertion failure when vlib_time_now() is called with a vm corresponding to a different thread.

Use thread-specific vlib_main_t *vm pointers to avoid problems with different threads accessing the same vlib_main_t data structure. This avoids crashing when ipfix logging is enabled and several threads are used.

2018-05-13Improve ipfix template packet rewrite constructionDave Barach1-9/+27
Instead of repeatedly cutting, pasting, and hacking to create a new callback, use vnet_flow_rewrite_generic_callback(). Add three arguments to the flow rewrite callback: (in) pointer to an array of report elements, (in) length of array, (out) pointer to the stream index Change existing code prototypes. Code owners encouraged to evaluate whether they can use the generic callback or not, at leisure. /* ipfix field definitions for a particular report */ typedef struct { u32 info_element; u32 size; } ipfix_report_element_t; Best generated like so: _(sourceIPv4Address, 4) \ _(destinationIPv4Address, 4) \ _(sourceTransportPort, 2) \ _(destinationTransportPort, 2) \ _(protocolIdentifier, 1) \ _(flowStartMicroseconds, 8) \ _(flowEndMicroseconds, 8) static ipfix_report_element_t simple_report_elements[] = { foreach_simple_report_ipfix_element }; ... /* Set up the ipfix report */ memset (&a, 0, sizeof (a)); a.is_add = 1 /* to enable the report */ ; a.domain_id = 1 /* pick a domain ID */ ; a.src_port = UDP_DST_PORT_ipfix /* src port for reports */ ; a.rewrite_callback = vnet_flow_rewrite_generic_callback; a.report_elements = simple_report_elements; a.n_report_elements = ARRAY_LEN (simple_report_elements); a.stream_indexp = &jim->stream_index; a.flow_data_callback = simple_flow_data_callback; /* Create the report */ rv = vnet_flow_report_add_del (frm, &a, &template_id); if (rv) return rv; ...
