bpf: test for AND edge cases
These two tests are based on the work done for f23cc643f9ba. The first test is just a basic one to make sure we don't allow AND'ing negative values, even if it would result in a valid index for the array. The second is a cleaned up version of the original testcase provided by Jann Horn that resulted in the commit.

zzer was able to trigger a divide by zero, when TCP window scaling is not enabled. SO_RCVBUF can be used not only to increase sk_rcvbuf, also to decrease it below current receive buffers utilization. If mss is negative or 0, just return a zero TCP window.

Miller <davem@davemloft.net> 2017-02-01net/sched: matchall: Fix configuration raceYotam Gigi1-82/+45 In the current version, the matchall internal state is split into two structs: cls_matchall_head and cls_matchall_filter. This makes little sense, as matchall instance supports only one filter, and there is no situation where one exists and the other does not. In addition, that led to some races when filter was deleted while packet was processed. Unify that two structs into one, thus simplifying the process of matchall creation and deletion. As a result, the new, delete and get callbacks have a dummy implementation where all the work is done in destroy and change callbacks, as was done in cls_cgroup.
