2020-05-04misc: binary api fuzz test fixesDave Barach2-0/+188
Add a hook to src/vlibapi/api_shared.c to fuzz (screw up) binary API messages, e.g. by xoring random data into them before processing. We specifically exempt client connection messages, and inband debug CLI messages. We step over msg_id, client index, client context, and sw_if_index. Otherwise, "make test" vectors fail too rapidly to learn anything. The goal is to reduce the number of crashes caused to zero. We're fairly close with this patch. Add vl_msg_api_max_length(void *mp), which returns the maximum plausible length for a binary API message. Use it to hardern vl_api_from_api_to_new_vec(...) which takes an additional argument - message pointer - so it can verify that astr->length is sane. If it's not sane, return a u8 *vector of the form "insane astr->length nnnn\0". Verify array lengths in vl_api_dhcp6_send_client_message_t_handler(...) and vl_api_dhcp6_pd_send_client_message_t_handler(...). Add a fairly effective binary API fuzz hook to the unittest plugin, and modify the "make test" framework.py to pass "api-fuzz { on|off }" to enable API fuzzing: "make API_FUZZ=on TEST=xxx test-debug" or similar Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I0157267652a163c01553d5267620f719cc6c3bde

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>

2020-02-25vlib: 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.
