2020-04-22misc: asan: do not poison memory after munmap()Benoît Ganne1-1/+0
It is a bad idea to poison memory after munmap because the address space can be reused (eg. for global data of dlopen()ed object) and ASan model allows access by default. Moreover, access to a stale address space will fault. Type: fix Change-Id: I356de422f255447d9d50a3a71fb0c2eaa790d731 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2020-03-10vppinfra: improve timebase resilienceDave Barach1-3/+20
Deal with arbitrary kernel reference time changes: for example, yanking the kernel reference clock back to a time before vpp started. Best practice involves aligning the kernel reference clock with reality prior to starting apps which use 10us granularity timers. Compute change in the reference and cpu clocks. Recompute the vpp start time reference and and total cpu clock count, using the current clock tick rate. Next, compute a new clock rate sample. If the sample seems sane, factor it into the exponentially smoothed clock rate and recalculate total cpu ticks based on the new clock rate.

2020-02-25svm: refactor fifoFlorin Coras2-10/+21
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>
