2024-02-19ipsec: check each packet for no algs in esp-encryptMatthew Smith1-1/+23
In esp_encrypt_inline(), if two or more consecutive packets are associated with the same SA which has no crypto or integrity algorithms set, only the first one gets dropped. Subsequent packets either get sent (synchronous crypto) or cause a segv (asynchronous crypto). The current SA's index and pool entry are cached before it can be determined whether the packet should be dropped due to no algorithms being set. The check for no algorithms is only performed when the cached SA index is different than the SA index for the current packet. So packets after the first one associated with the "none" alg SA aren't handled properly. This was broken by my previous commit ("ipsec: keep esp encrypt pointer and index synced") which fixed a segv that occurred under a different set of circumstances. Check whether each packet should be dropped instead of only checking when a new SA is encountered. Update unit tests: - Add a test for no algs on tunnel interface which enables asynchronous crypto. - Send more than one packet in the tests for no algs.

2023-02-06ipsec: fix SA names consistency in testsArthur de Kerhor1-80/+80
In some IPsec tests, the SA called scapy_sa designs the SA that encrypts Scapy packets and decrypts them in VPP, and the one called vpp_sa the SA that encrypts VPP packets and decrypts them with Scapy. However, this pattern is not consistent across all tests. Some tests use the opposite logic. Others even mix both correlating scapy_tra_spi with vpp_tra_sa_id and vice-versa. Because of that, sometimes, the SA called vpp_sa_in is used as an outbound SA and vpp_sa_out as an inbound one. This patch forces all the tests to follow the same following logic: - scapy_sa is the SA used to encrypt Scapy packets and decrypt them in VPP. It matches the VPP inbound SA. - vpp_sa is the SA used to encrypt VPP packets and decrypt them in Scapy. It matches the VPP outbound SA.

Type: improvement If an SA protecting an IPv6 tunnel interface has UDP encapsulation enabled, the code in esp_encrypt_inline() inserts a UDP header but does not set the next protocol or the UDP payload length, so the peer that receives the packet drops it. Set the next protocol field and the UDP payload length correctly. The port(s) for UDP encapsulation of IPsec was not registered for IPv6.

2022-05-10tests: replace pycodestyle with blackKlement Sekera1-1055/+1389
Drop pycodestyle for code style checking in favor of black. Black is much faster, stable PEP8 compliant code style checker offering also automatic formatting. It aims to be very stable and produce smallest diffs. It's used by many small and big projects. Running checkstyle with black takes a few seconds with a terse output. Thus, test-checkstyle-diff is no longer necessary. Expand scope of checkstyle to all python files in the repo, replacing test-checkstyle with checkstyle-python. Also, fixstyle-python is now available for automatic style formatting. Note: python virtualenv has been consolidated in test/Makefile, test/requirements*.txt which will eventually be moved to a central location. This is required to simply the automated generation of docker executor images in the CI.

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
2021-03-25stats: python vpp_stats rewrite to access stat segment directlyOle Troan1-96/+48
This module implement Python access to the VPP statistics segment. It accesses the data structures directly in shared memory. VPP uses optimistic locking, so data structures may change underneath us while we are reading. Data is copied out and it's important to spend as little time as possible "holding the lock". Counters are stored in VPP as a two dimensional array. Index by thread and index (typically sw_if_index). Simple counters count only packets, Combined counters count packets and octets. Counters can be accessed in either dimension. stat['/if/rx'] - returns 2D lists stat['/if/rx'][0] - returns counters for all interfaces for thread 0 stat['/if/rx'][0][1] - returns counter for interface 1 on thread 0 stat['/if/rx'][0][1]['packets'] - returns the packet counter for interface 1 on thread 0 stat['/if/rx'][:, 1] - returns the counters for interface 1 on all threads stat['/if/rx'][:, 1].packets() - returns the packet counters for interface 1 on all threads stat['/if/rx'][:, 1].sum_packets() - returns the sum of packet counters for interface 1 on all threads stat['/if/rx-miss'][:, 1].sum() - returns the sum of packet counters for interface 1 on all threads for simple counters Type: refactor Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I1fe7f7c7d11378d06be8276db5e1900ecdb8f515 Signed-off-by: Ole Troan <ot@cisco.com>
