2019-07-22powerpc/tm: Fix oops on sigreturn on systems without TMMichael Neuling2-0/+8
On systems like P9 powernv where we have no TM (or P8 booted with ppc_tm=off), userspace can construct a signal context which still has the MSR TS bits set. The kernel tries to restore this context which results in the following crash: Unexpected TM Bad Thing exception at c0000000000022fc (msr 0x8000000102a03031) tm_scratch=800000020280f033 Oops: Unrecoverable exception, sig: 6 [#1] LE PAGE_SIZE=64K MMU=Hash SMP NR_CPUS=2048 NUMA pSeries Modules linked in: CPU: 0 PID: 1636 Comm: sigfuz Not tainted 5.2.0-11043-g0a8ad0ffa4 #69 NIP: c0000000000022fc LR: 00007fffb2d67e48 CTR: 0000000000000000 REGS: c00000003fffbd70 TRAP: 0700 Not tainted (5.2.0-11045-g7142b497d8) MSR: 8000000102a03031 <SF,VEC,VSX,FP,ME,IR,DR,LE,TM[E]> CR: 42004242 XER: 00000000 CFAR: c0000000000022e0 IRQMASK: 0 GPR00: 0000000000000072 00007fffb2b6e560 00007fffb2d87f00 0000000000000669 GPR04: 00007fffb2b6e728 0000000000000000 0000000000000000 00007fffb2b6f2a8 GPR08: 0000000000000000 0000000000000000 0000000000000000 0000000000000000 GPR12: 0000000000000000 00007fffb2b76900 0000000000000000 0000000000000000 GPR16: 00007fffb2370000 00007fffb2d84390 00007fffea3a15ac 000001000a250420 GPR20: 00007fffb2b6f260 0000000010001770 0000000000000000 0000000000000000 GPR24: 00007fffb2d843a0 00007fffea3a14a0 0000000000010000 0000000000800000 GPR28: 00007fffea3a14d8 00000000003d0f00 0000000000000000 00007fffb2b6e728 NIP [c0000000000022fc] rfi_flush_fallback+0x7c/0x80 LR [00007fffb2d67e48] 0x7fffb2d67e48 Call Trace: Instruction dump: e96a0220 e96a02a8 e96a0330 e96a03b8 394a0400 4200ffdc 7d2903a6 e92d0c00 e94d0c08 e96d0c10 e82d0c18 7db242a6 <4c000024> 7db243a6 7db142a6 f82d0c18 The problem is the signal code assumes TM is enabled when CONFIG_PPC_TRANSACTIONAL_MEM is enabled. This may not be the case as with P9 powernv or if `ppc_tm=off` is used on P8. This means any local user can crash the system. Fix the problem by returning a bad stack frame to the user if they try to set the MSR TS bits with sigreturn() on systems where TM is not supported. Found with sigfuz kernel selftest on P9. This fixes CVE-2019-13648.

2019-07-21vrf: make sure skb->data contains ip header to make routingPeter Kosyh1-23/+35
vrf_process_v4_outbound() and vrf_process_v6_outbound() do routing using ip/ipv6 addresses, but don't make sure the header is available in skb->data[] (skb_headlen() is less then header size). Case: 1) igb driver from intel. 2) Packet size is greater then 255. 3) MPLS forwards to VRF device. So, patch adds pskb_may_pull() calls in vrf_process_v4/v6_outbound() functions.

As pointed out by Firo Yang, a netdev tx timeout may trigger just before an ethtool set_channels operation is started. be_tx_timeout(), which dumps some queue structures, is not written to run concurrently with be_update_queues(), which frees/allocates those queues structures. Add some synchronization between the two.

2019-07-20dt-bindings: riscv: Limit cpus schema to only check RiscV 'cpu' nodesRob Herring1-82/+61
Matching on the 'cpus' node was a bad choice because the schema is incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus schema which checks the general structure, it is also redundant to do so in the Risc-V CPU schema. The downside is one could conceivably mix different architecture's cpu nodes or have typos in the compatible string. The latter problem pretty much exists for every schema.
