2020-03-19tcp: force deschedule if no send space availableFlorin Coras4-12/+13

2020-03-19session tcp udp: consolidate transport snd apisFlorin Coras6-49/+123
Type: improvement Use only one api to retrieve transport send parameters. Additionally, allow transports to request postponing and descheduling of events. With this, tcp now requests descheduling of sessions when the connections are stuck probing for zero snd_wnd Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I722c974f3e68fa15424c519a1fffacda43af050c

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>

2020-02-17misc: fix coverity warningsDave Barach1-1/+1
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.
