2020-10-21virtio: run process to send interrupts to input nodesMohsin Kazmi4-17/+112
Type: improvement virtio interfaces support packet coalescing and buffering which depends on timer expiry to flush the stored packets periodically. virtio input node checks timer expiry and schedules tx queue accordingly. In poll mode, timer expiry is handled naturally, as input node runs periodically. In interrupt mode, virtio input node depends on the interrupts send from backend. Stored packets could starve, if there would not be interrupts to input node. This patch implements a process node which periodically sends interrupt to virtio input node given coalescing or buffering feature is enabled on an interface.

2020-10-16ipsec: fix instance, and cli del for new ipsec interfaceEric Kinzie2-4/+4
- use user instance number in interface name Restore the behavior of previous versions where the IPsec tunnel interface name contained the value of the user-provided instance number. For example, a command similar to create ipsec tunnel local-ip . . . instance 5 would result in the creation of interface "ipsec5". - ipsec: delete tunnel protection when asked The "ipsec tunnel protect" command will parse a "del" argument but does not undo the tunnel protection, leaving the SAs hanging around with reference counts that were incremented by a previous invocation of the command. Allow the tunnel protection to be deleted and also update the help text to indicate that deletion is an option. - test: ipsec: add test for ipsec interface instance Also cleanup (unconfig) after TestIpsecItf4 NULL algo test.

2020-10-13stats: counters data modelOle Troan2-3/+4
This adds a new data model for counters. Specifying the errors severity and unit. A later patch will update vpp_get_stats to take advantage of this. Only the map plugin is updates as an example. New .api language: A new "counters" keyword to define counter sets. counters map { none { severity info; type counter64; units "packets"; description "valid MAP packets"; }; bad_protocol { severity error; type counter64; units "packets"; description "bad protocol"; }; }; Each counter has 4 keywords. severity, which is one of error, info or warn. A type, which is one of counter64 or gauge64. units, which is a text field using units from YANG. paths { "/err/ip4-map" "map"; "/err/ip6-map" "map"; "/err/ip4-t-map" "map"; "/err/ip6-t-map" "map"; }; A new paths keyword that maps the counter-set to a path in the stats segment KV store. Updated VPP CLI to include severity so user can see error counter severity.

2020-10-12l2: mark l2 fib uninitialized after clearingMatthew Smith1-0/+2
Type: fix After clearing the l2fib with 'vppctl clear l2fib', a SEGV occurs the next time a MAC address is learned. In l2fib_clear_table(), the l2fib bihash is freed and then l2fib_table_init() is called to reinitialize it. l2fib_table_init() will not do anything if l2fib_main.mac_table_initialized is set to 1. Reset the value of l2fib_main.mac_table_initialized to 0 before calling l2fib_table_init(). Change-Id: I87f1a3f9a46c951f36c1c0a5ab795b0ec08c81a8 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2020-10-08ipsec: Allow SAs with NULL auth &crypto on IPSec interfaceNeale Ranns1-2/+3
Type: improvement on the dedicated IPSec interface, the SA describes the peer, so it is not possible to forward to a peer for which there is no SA. Therefore if an SA is added with NULL auth and integ then this explicitly states that this is what the peer desires. on the contrary on the IP-IP/GRE interface, in the absence of protection and an SA, then the traffic is sent in the clear. So adding NULL auth/crypto iSA is a means to describe that the peer should not be sent traffic. Signed-off-by: Neale Ranns <nranns@cisco.com> Change-Id: I7ad2d466cc74eb7ff8c4c84e0d7897d06e2fcf86
