The syz repro looks bpf related, and essentially the same repro is in lots of other open syzbot reports which I've assigned to the bpf subsystem... https://lore.kernel.org/lkml/20190624050114.GA30702@sol.localdomain/ {"threaded":true,"repeat":true,"procs":6,"sandbox":"none","fault_call":-1,"tun":true,"netdev":true,"resetnet":true,"cgroups":true,"binfmt_misc":true,"close_fds":true,"tmpdir":true,"segv":true} bpf$MAP_CREATE(0x0, &(0x7f0000000280)={0xf, 0x4, 0x4, 0x400, 0x0, 0x1}, 0x3c) socket$rxrpc(0x21, 0x2, 0x800000000a) r0 = socket$inet6_tcp(0xa, 0x1, 0x0) setsockopt$inet6_tcp_int(r0, 0x6, 0x13, &(0x7f00000000c0)=0x100000001, 0x1d4) connect$inet6(r0, &(0x7f0000000140), 0x1c) bpf$MAP_CREATE(0x0, &(0x7f0000000000)={0x5}, 0xfffffffffffffdcb) bpf$MAP_CREATE(0x2, &(0x7f0000003000)={0x3, 0x0, 0x77fffb, 0x0, 0x10020000000, 0x0}, 0x2c) setsockopt$inet6_tcp_TCP_ULP(r0, 0x6, 0x1f, &(0x7f0000000040)='tls\x00', 0x4)
