2020-02-26svm: support multi-chunk fifo chunk allocFlorin Coras1-4/+4

2020-02-25unittest: Skip string test case for sizeof (src) > sizeof (dst)Steven Luong1-4/+13
coverity complains that the subject test may cause dst buffer overrun problem and it is right. The problem is when __builtin_constant_p (n) returns true, memcpy_s_inline skips all the errors checking and does the copy blindly. Please see the code in memcpy_s_inline. The fix is to skip the subject test when the aformentioned builtin function returns true. Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I50de91cc0c853a134b3bcf3b0cd8d45d7668b092

2020-02-25svm: refactor fifoFlorin Coras1-799/+724
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>
2020-02-25svm: refactor fifo chunk trackingFlorin Coras1-2/+12
Avoid tracking with rbtrees all of the chunks associated to a fifo. Instead, only track chunks when doing out-of-order operations (peek or ooo enqueue). Type: refactor Change-Id: I9f8bd266211746637d98e6a12ffc4b2d6346950a Signed-off-by: Florin Coras <fcoras@cisco.com>
2020-02-25vlib: Punt reason allocation listener enable/disable callbackNeale Ranns1-2/+4
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.
