2022-02-01virtio: coverity woes -- divide by zeroSteven Luong1-0/+7
Coverity complains the expression, j % vif->num_txq, may encounter divide by zero. While there is little chance that vif->num_txq is zero, it is easy to prevent divide by zero if vif->num_txq is ever zero.

2022-01-31ip: reassembly - add a way to disable for forusKlement Sekera11-34/+305
Add API to disable full reassembly of "forus" packets. Mark packets passing through ip[4|6]-local nodes with a new buffer flag and check for that flag in reassembly. Enable IP6 "forus" full reassembly by default to be consistent with existing IP4 setting.

2022-01-18virtio: remove admin-up flag during interface creationMohsin Kazmi2-4/+0
Type: fix During the interface creation time, (by default) admin-up flag is locally set for tap and virtio interfaces. While, in VPP the state of these interfaces are still admin-down. User needs to explicitly call 'set interface state <interface-name> up' to admin-up the newly created tap or virtio interface(s) in VPP. So, this behavior is inconsistent. This patch fixes the issue to have consistent behavior for given interface between local and global administration state.

2022-01-11linux-cp: Add VPP->Linux synchronizationPim van Pelt2-1/+46
Part 1 -- notes in https://ipng.ch/s/articles/2021/08/13/vpp-2.html Add the ability for VPP to copy out (sync) its state from the dataplane to Linux Interface Pairs, when they exist. Gated by a configuration flag (linux-cp { lcp-sync }), and by a CLI option to toggle on/off, synchronize the following events: - Interface state changes - Interface MTU changes - Interface IPv4/IPv6 address add/deletion In VPP, subints can have any link state and MTU, orthogonal to their phy. In Linux, setting admin-down on a phy forces its children to be down as well. Also, in Linux, MTU of children must not exceed that of the phy. Add a state synchronizer which walks over phy+subints to ensure Linux and VPP end up in the same consistent state. Part 2 -- notes in https://ipng.ch/s/articles/2021/08/15/vpp-3.html Add the ability for VPP to autocreate sub-interfaces of existing Linux Interface pairs. Gated by a configuration flag (linux-cp { lcp-auto-subint }), and by a CLI option to toggle on/off, synchronize the following event: - Sub-interface creation (dot1q, dot1ad, QinQ and QinAD) A few other changes: - Add two functions into netlink.[ch] to delete ip4 and ip6 addresses. - Remove a spurious logline (printing MTU) in netlink.c. - Resolve a TODO around vnet_sw_interface_supports_addressing() Type: improvement Signed-off-by: Pim van Pelt <pim@ipng.nl> Change-Id: I34fc070e80af4013be58d7a8cbf64296cc760e4e Signed-off-by: Pim van Pelt <pim@ipng.nl>

2022-01-10session: deschedule sessions with no data to sendFlorin Coras3-3/+26
This ensures the scheduler always tracks sessions that are descheduled, i.e., do not have events in the old io events list. When app retries to send, clear descheduled flag and potentially the pacer. Consequently, transports no longer need to reset the pacer when sessions are rescheduled after a long app tx pause. This also fixes a tcp bug whereby the pacer was reset too often when snd_una was equal to snd_nxt as there was no way to distinguish betwen app tx breaks and congestion.

2022-01-05crypto: encrypt/decrypt queues sw_schedulerJakub Wysocki4-34/+99
Type: improvement Previously multiple sw crypto scheduler queues per core design caused unaverage frame processing rate for each async op ID – the lower the op ID is the highly likely they are processed first. For example, when a RX core is feeding both encryption and decryption jobs of the same crypto algorithm to the queues at a high rate, in the mean time the crypto cores have no enough cycles to process all: the jobs in the decryption queue are less likely being processed, causing packet drop. To improve the situation this patch makes every core only owning a two queues, one for encrypt operations and one for decrypt. The queue is changed either after checking each core or after founding a frame to process. All crypto jobs with different algorithm are pushed to thoses queues and are treated evenly. In addition, the crypto async infra now uses unified dequeue handler, one per engine. Only the active engine will be registered its dequeue handler in crypto main.
