2019-07-15session: allow transports to generate closed notificationsFlorin Coras6-27/+44
In contrast to the closing notification, whereby a transport informs the session layer that is beginning the closing procedure, this allows transports to notify the session layer of the fact that the transport is "fully" closed, i.e., it expects no more data. Also: - adds app closed state for sessions - changes tcp to have it notify when an active close has finished Type: feature Change-Id: I13c738006c03f85015e05ab82843a33a69382aaf Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-07-12ipsec: drop outbound ESP when no crypto alg setMatthew Smith4-5/+162
Type: fix If a tunnel interface has the crypto alg set on the outbound SA to IPSEC_CRYPTO_ALG_NONE and packets are sent out that interface, the attempt to write an ESP trailer on the packet occurs at the wrong offset and the vnet buffer opaque data is corrupted, which can result in a SEGV when a subsequent node attempts to use that data. When an outbound SA is set on a tunnel interface which has no crypto alg set, add a node to the ip{4,6}-output feature arcs which drops all packets leaving that interface instead of adding the node which would try to encrypt the packets.

2019-07-10vlib: Replace timer in CLI with an event processChris Luke1-16/+140
The CLI code, when it accepts a socket connection, ran a timer for each session that would ensure the CLI session was started should the TELNET negotiation stage fail to complete. It has since transpired that this is unsafe; the timer is capable of firing in critical sections, during a spinlock, and since we peform non-trivial things in the handler it can cause a deadlock. This was reported recently in VPP-1711 but a search of history suggests this may also be (one of) the causes in VPP-1413. This change replaces that method with an event-driven process. The process is created when the first socket connection is accepted. When new connections are created the process is sent an event to register the new session in a list. That event process has a loop that evaluates the list of oustanding sessions and if a deadline expires, their session is started if it has not been already, and then removed from the list. If we have pending sessions then the loop waits on a timer or an event; if there are no sessions it waits on events only.

2019-07-09gbp: Ownership of dynamically created vxlan-gbp tunnels managed via gbp_itfNeale Ranns20-396/+694
Type: fix This solves the ownership of vxlan-gbp tunnels. When the last reference of these goes away they need to be deleted. Currently there are two owners; gbp_itf via gef_itf and the lock held by the gbp_endpoint_location_t. The problem is that the loc removes its reference whilst the fwd still holds the gbp_itf, and things go wrong. This change moves the lifecycle management of the vxlan-gbp tunnel to the gbp_itf. When the last lock of the gbp_itf goes, so does the tunnel. now both the EP's loc and fwd can hold a lock on the gbp_itf and it's only removed when required. The other change is the management of the 'user' of the gbp_itf. Since each user can enable and disable different features, it's the job of the gbp_itf to apply the combined set. determining a unique 'uesr' from the caller was near impossible, so I moved that to the gbp_itf, and return the allocated user, hence the 'handle' that encodes both user and interface. The hash table maps from sw_if_index to pool index. Change-Id: I4c7bf4c0e5dcf33d1c545f262365e69151febcf4 Signed-off-by: Neale Ranns <nranns@cisco.com>

If the corresponding vpp plugin is absent, return a non-zero clib_error_t * from vat_plugin_register ("xxx plugin not loaded"). The vat plugin calls dlclose on the vat plugin, and it disappears. Depending on the plugin configuration, this can reduce the vpp virtual size by several gigabytes. Added a VAT_PLUGIN(<plugin-name>) macro to vat_helper_macros, clean up boilerplate vat_plugin_register() implementations. Fixed a number of non-standard vat_plugin_register methods.

clib_net_to_host_f64, clib_host_to_net_f64 are now implemented as '=', https://gerrit.fd.io/r/#/c/20406/ set papi to match. - all f64 api references are now wrapped with clib_net_to_host_f64 or clib_host_to_net_f64. IEEE f64 endianess is not defined. If clib_net_to_host_f64 and clib_host_to_net_f64 are later defined in VPP as big-endian, it is a single character change in the papi vpp_serializer. Note: This breaks the api in a manner that would not be detected by the flag day initiative. The scope is small. This only impacts map.api, which applied the u64 transformation, while the gbp api uses '='. The implementation of "=" raises issues for the papi socket implementation if used between systems of differing endianess. See Vratko's comments. - Added get_f64_endian_value() to api to allow client to verify endianess of f64's.
