2022-02-21tests: add enhanced packet counter verificationKlement Sekera3-40/+175
Add support for inline packet counter verification to send_and_* functions. Diff dictionary is a dictionary of dictionaries of interesting stats: diff_dictionary = { "err" : { '/error/counter1' : 4, }, sw_if_index1 : { '/stat/segment/counter1' : 5, '/stat/segment/counter2' : 6, }, sw_if_index2 : { '/stat/segment/counter1' : 7, }, } It describes a per sw-if-index diffset, where each key is stat segment path and value is the expected change for that counter for sw-if-index. Special case string "err" is used for error counters. This then allows more precise packet counter verification by first defining a "zero" dictionary, e.g. for ED NAT: cls.no_diff = StatsDiff({ pg.sw_if_index: { '/nat44-ed/in2out/fastpath/tcp': 0, '/nat44-ed/in2out/fastpath/udp': 0, '/nat44-ed/in2out/fastpath/icmp': 0, '/nat44-ed/in2out/fastpath/drops': 0, '/nat44-ed/in2out/slowpath/tcp': 0, '/nat44-ed/in2out/slowpath/udp': 0, '/nat44-ed/in2out/slowpath/icmp': 0, '/nat44-ed/in2out/slowpath/drops': 0, '/nat44-ed/in2out/fastpath/tcp': 0, '/nat44-ed/in2out/fastpath/udp': 0, '/nat44-ed/in2out/fastpath/icmp': 0, '/nat44-ed/in2out/fastpath/drops': 0, '/nat44-ed/in2out/slowpath/tcp': 0, '/nat44-ed/in2out/slowpath/udp': 0, '/nat44-ed/in2out/slowpath/icmp': 0, '/nat44-ed/in2out/slowpath/drops': 0, } for pg in cls.pg_interfaces }) and then to specify only changed counters directly when calling one of send_and_* functions: self.send_and_assert_no_replies( self.pg0, pkts, msg="i2o pkts", stats_diff=self.no_diff | { "err": { '/err/nat44-ed-in2out-slowpath/out of ports': len(pkts), }, self.pg0.sw_if_index: { '/nat44-ed/in2out/slowpath/drops': len(pkts), }, } ) operator | is overloaded by StatsDiff class to perform a deep merge operation, so in above case, dictionaries for "err" and self.pg0.sw_if_index do not overwrite whole sub-dictionaries, rather the contents are merged, assuring that all the remaining counters are verified to be zero.

Implement proper state machine based on above RFCs. ACKs to SYNs/FINs are no longer required/tracked. This is more friendly to peers and accounts for lost packets and retransmits. This change also means that all traffic is translated and forwarded while in transitory timeout, which helps delivering e.g. retransmitted FINs, FINACKs and other messages. Also support reopening a session in transitory timeout after seeing both FINs by seeing both SYNs again. This helps quick connection reestablishment if the peers want to.

2021-11-19fib: Don't use [midchain] adjacencies to change an interface's feature arcNeale Ranns1-3/+29
Type: fix Using the adjacency to modify the interface's feature arc doesn't work, since there are potentially more than one adj per-interface. Instead have the interface, when it is created, register what the end node of the feature arc is. This end node is then also used as the interface's tx node (i.e. it is used as the adjacency's next-node). rename adj-midhcain-tx as 'tunnel-output', that's a bit more intuitive. There's also a fix in config string handling to: 1- prevent false sharing of strings when the end node of the arc is different. 2- call registered listeners when the end node is changed For IPSec the consequences are that one cannot provide per-adjacency behaviour using different end-nodes - this was previously done for the no-SA and an SA with no protection. These cases are no handled in the esp-encrypt node. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: If3a83d03a3000f28820d9a9cb4101d244803d084

2021-11-05unittest: gcc-11 errors for clib_strcpy, clib_strstr, clib_strcat, and ↵Steven Luong1-3/+3
clib_strncat There are 3 versions of the string functions. For example, for strcpy, they are 1. strcpy(dst, src) -- the legacy unsafe version 2. strcpy_s(dst, dmax, src) -- C11 safeC version which has an addition argument named dmax. 3. clib_strcpy(dst,src) -- clib version to enable legacy code that uses strcpy to make use of strcpy_s without adding the additional argument, dmax, which is required by the C11 safeC version. The implementation for the clib version is to artificially provide dmax to strcpy_s. In this case, it uses 4096 which assumes that if the legacy code works without blowing up, it is likely to work with the clib version without problem. gcc-11 is getting smarter by checking if dmax is within the object's boundary. When the object is declared as static array, it will flag a warning/error if dmax is out of bound for the object since the real size of dst can be determined at compile time. There is no way to find the real size of dst if the object is dynamically allocated at compile time. For this reason, we simply can't provide support for the clib version of the function anymore. If any code is using the clib version, the choice is to migrate to the safeC version.

2021-10-22fib: Don't back walk from a path-list when a child fist attaches.Neale Ranns1-1/+11
Type: fix If the walk is triggered when the child is added, then that child is visited in the walk. However, since it is just attahcing to the path-list it may not, or indeed cannot, have all the context it needs to successfully handle the walk. In the case of MPLS tunnel, it does not have the path extensions ready, and cannot since the path extensions need to resolve on the path-list.
