2019-02-18IPSEC: move SA counters into the stats segmentNeale Ranns1-2/+6
1) stats are accessed via the stat segment which is more condusive to monitoring 2) stats are accurate in the presence of multiple threads. There's no guarantee that an SA is access from only one worker. Change-Id: Id5e217ea253ddfc9480aaedb0d008dea031b1148 Signed-off-by: Neale Ranns <nranns@cisco.com>
2019-02-14Add -fno-common compile optionBenoît Ganne1-0/+2
-fno-common makes sure we do not have multiple declarations of the same global symbol across compilation units. It helps debug nasty linkage bugs by guaranteeing that all reference to a global symbol use the same underlying object. It also helps avoiding benign mistakes such as declaring enum as global objects instead of types in headers (hence the minor fixes scattered across the source).

2019-02-07IPSEC: no second lookup after tunnel encapNeale Ranns1-13/+17
in the same maaner as with other tunnel tyeps we use the FIB to cache and track the destination used to reach the tunnel endpoint. Post encap we can then ship the packet straight to this adjacency and thus elide the costly second lookup. - SA add and del function so they can be used both directly from the API and for tunnels. - API change for the SA dump to use the SA type - ipsec_key_t type for convenience (copying, [un]formating) - no matching tunnel counters in ipsec-if-input Change-Id: I9d144a59667f7bf96442f4ca66bef5c1d3c7f1ea Signed-off-by: Neale Ranns <nranns@cisco.com>
2018-12-11Add IPSec interface FIB index for TX packetPierre Pfister1-2/+2
This patch adds a configuration parameter to IPSec tunnels, enabling custom FIB selection for encapsulated packets. Although this option could also be used for policy-based IPSec, this change only enables it for virtual-tunnel-interface mode. Note that this patch does change the API default behavior regarding TX fib selection for encapsulated packets. Previous behavior was to use the same FIB after and before encap. The new default behavior consists in using the FIB 0 as default. Change-Id: I5c212af909940a8cf6c7e3971bdc7623a2296452 Signed-off-by: Pierre Pfister <ppfister@cisco.com>

All the changes have been done so that VPP can still be built against current openssl API whilst forward-looking to version 1.1.0.

2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace1-0/+1
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included. This results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.

2017-04-06Use thread local storage for thread indexDamjan Marion1-6/+7
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-02-17Implemented IKEv2 initiator features:Radu Nicolau1-0/+2
- IKE_SA_INIT and IKE_AUTH initial exchanges - Delete IKA SA - Rekey and delete Child SA - Child SAs lifetime policy To set up one VPP instance as the initiator use the following CLI commands (or API equivalents): ikev2 profile set <id> responder <interface> <addr> ikev2 profile set <id> ike-crypto-alg <crypto alg> <key size> ike-integ-alg <integ alg> ike-dh <dh type> ikev2 profile set <id> esp-crypto-alg <crypto alg> <key size> esp-integ-alg <integ alg> esp-dh <dh type> ikev2 profile set <id> sa-lifetime <seconds> <jitter> <handover> <max bytes> and finally ikev2 initiate sa-init <profile id> to initiate the IKE_SA_INIT exchange Child SA re-keying process: 1. Child SA expires 2. A new Child SA is created using the Child SA rekey exchange 3. For a set time both SAs are alive 4. After the set time interval expires old SA is deleted Any additional settings will not be carried over (i.e. settings of the ipsec<x> interface associated with the Child SA) CLI API additions: ikev2 profile set <id> responder <interface> <addr> ikev2 profile set <id> ike-crypto-alg <crypto alg> <key size> ike-integ-alg <integ alg> ike-dh <dh type> ikev2 profile set <id> esp-crypto-alg <crypto alg> <key size> esp-integ-alg <integ alg> esp-dh <dh type> ikev2 profile set <id> sa-lifetime <seconds> <jitter> <handover> <max bytes> ikev2 initiate sa-init <profile id> ikev2 initiate del-child-sa <child sa ispi> ikev2 initiate del-sa <sa ispi> ikev2 initiate rekey-child-sa <profile id> <child sa ispi> Sample configurations: Responder: ikev2 profile add pr1 ikev2 profile set pr1 auth shared-key-mic string Vpp123 ikev2 profile set pr1 id local fqdn vpp.home.responder ikev2 profile set pr1 id remote fqdn vpp.home.initiator ikev2 profile set pr1 traffic-selector remote ip-range 192.168.125.0 - 192.168.125.255 port-range 0 - 65535 protocol 0 ikev2 profile set pr1 traffic-selector local ip-range 192.168.124.0 - 192.168.124.255 port-range 0 - 65535 protocol 0 Initiator: ikev2 profile add pr1 ikev2 profile set pr1 auth shared-key-mic string Vpp123 ikev2 profile set pr1 id local fqdn vpp.home.initiator ikev2 profile set pr1 id remote fqdn vpp.home.responder ikev2 profile set pr1 traffic-selector local ip-range 192.168.125.0 - 192.168.125.255 port-range 0 - 65535 protocol 0 ikev2 profile set pr1 traffic-selector remote ip-range 192.168.124.0 - 192.168.124.255 port-range 0 - 65535 protocol 0 ikev2 profile set pr1 responder TenGigabitEthernet3/0/1 192.168.40.20 ikev2 profile set pr1 ike-crypto-alg aes-cbc 192 ike-integ-alg sha1-96 ike-dh modp-2048 ikev2 profile set pr1 esp-crypto-alg aes-cbc 192 esp-integ-alg sha1-96 esp-dh ecp-256 ikev2 profile set pr1 sa-lifetime 3600 10 5 0 Change-Id: I1db9084dc787129ea61298223fb7585a6f7eaf9e Signed-off-by: Radu Nicolau <radu.nicolau@intel.com>
