2020-02-25svm: refactor fifoFlorin Coras4-91/+7
Type: refactor Switch from a wrapped byte space to a "continuous" one wherein fifo chunks are appended to the fifo as more data is enqueued and chunks are removed as data is dequeued. The fifo is still subject to a maximum size, i.e., maximum number of bytes that can be enqueued, so the max number of chunks associated to the fifo is also constrained. When enqueueing data, which must fit within the available free space, if not enough "supporting" chunk memory is available, the fifo asks the fifo segment for enough chunk memory to ensure that the write can succeed. To avoid allocating large amounts of small chunks due to small writes, if possible, the size of the chunks requested is lower capped by min_alloc. When dequeuing data, all the chunks that have been completely drained, i.e., head moved beyond the chunks’ end bytes, are unlinked from the fifo and returned to the fifo segment. The one exception to this is the last chunk which is never unlinked. Change-Id: I98c1dbd9135fb79650365c7e40c29238b96cd4ee Signed-off-by: Florin Coras <fcoras@cisco.com>

Type: improvement when using vlib_buffer_enqueue_to_next the 'nexts' parameter is an array of u16, but vnet_feautre_next takes a u32. this is a simple wrapper to address the impedence mismatch. Signed-off-by: Neale Ranns <nranns@cisco.com> Change-Id: I0fa86629e979e313344eb68442dc35a7b9537a8f

2020-02-25vlib: Punt reason allocation listener enable/disable callbackNeale Ranns5-23/+79
Type: improvement allow clients that allocate punt reasons to pass a callback function that is invoked when the first/last client registers to use/listen on that punt reason. This allows the client to perform some necessary configs that might not otherwise be enabled. IPSec uses this callback to register the ESP proto and UDP handling nodes, that would not otherwise be enabled unless a tunnel was present.

2020-02-20ip-neighbor: Fix aging timeoutVladimir Isaev1-12/+19
Before this patch VPP checked age for ARP/NDP records every 1e5 seconds for any configured aging time. This is 27 hours and it looks like misprint because 1e5 is the number of 10us ticks in a second. Also time to wait is now difference between aging time and time alive for nodes in alive state.

2020-02-17misc: fix coverity warningsDave Barach9-15/+18
Add an ALWAYS_ASSERT (...) macro, to (a) shut up coverity, and (b) check the indicated condition in production images. As in: p = hash_get(...); ALWAYS_ASSERT(p) /* was ASSERT(p) */ elt = pool_elt_at_index(pool, p[0]); This may not be the best way to handle a specific case, but failure to check return values at all followed by e.g. a pointer dereference isn't ok.
