Daniel Borkmann says: ==================== pull-request: bpf 2019-02-23 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Fix a bug in BPF's LPM deletion logic to match correct prefix length, from Alban. 2) Fix AF_XDP teardown by not destroying umem prematurely as it is still needed till all outstanding skbs are freed, from Björn. 3) Fix unkillable BPF_PROG_TEST_RUN under preempt kernel by checking signal_pending() outside need_resched() condition which is never triggered there, from Stanislav. 4) Fix two nfp JIT bugs, one in code emission for K-based xor, and another one to explicitly clear upper bits in alu32, from Jiong. 5) Add bpf list address to maintainers file, from Daniel. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
