|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several conflicts here. NFP driver bug fix adding nfp_netdev_is_nfp_repr() check to nfp_fl_output() needed some adjustments because the code block is in an else block now. Parallel additions to net/pkt_cls.h and net/sch_generic.h A bug fix in __tcp_retransmit_skb() conflicted with some of the rbtree changes in net-next. The tc action RCU callback fixes in 'net' had some overlap with some of the recent tcf_block reworking. Signed-off-by: David S. Miller <davem@davemloft.net>
| * nfp: refuse offloading filters that redirects to upper devicesPieter Jansen van Vuuren2017-10-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we did not ensure that a netdev is a representative netdev before dereferencing its private data. This can occur when an upper netdev is created on a representative netdev. This patch corrects this by first ensuring that the netdev is a representative netdev before using it. Checking only switchdev_port_same_parent_id is not sufficient to ensure that we can safely use the netdev. Failing to check that the netdev is also a representative netdev would result in incorrect dereferencing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Loading 64bit constants require up to 4 load immediates, since we can only load 16 bits at a time. If the 32bit halves of the 64bit constant are the same, however, we can save a cycle by doing a register move instead of two loads of 16 bits. Note that we don't optimize the normal ALU64 load because even though it's a 64 bit load the upper half of the register is a coming from sign extension so we can load it in one cycle anyway.

* | nfp: bpf: support accessing the stack beyond 64 bytesJakub Kicinski2017-10-243-14/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To access beyond 64th byte of the stack we need to set a new stack pointer register (LMEM is accessed indirectly through those pointers). Add a function for encoding local CSR access instruction. Use stack pointer number 3. Note that stack pointer registers allow us to index into 32 bytes of LMEM (with shift operations i.e. when operands are restricted). This means if access is crossing 32 byte boundary we must not use offsetting, we have to set the pointer to the exact address and move it with post-increments. We depend on the datapath placing the stack base address in GPR A22 for our use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we are performing unaligned stack accesses in the 32-64B window we have to do a read-modify-write cycle. E.g. for reading 8 bytes from address 17: 0: tmp = stack[16] 1: gprLo = tmp >> 8 2: tmp = stack[20] 3: gprLo |= tmp << 24 4: tmp = stack[20] 5: gprHi = tmp >> 8 6: tmp = stack[24] 7: gprHi |= tmp << 24 The load on line 4 is unnecessary, because tmp already contains data from stack[20]. For write we can optimize both loads and writebacks away.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stack is implemented by the LMEM register file. Unaligned accesses to LMEM are not allowed. Accesses also have to be 4B wide. To support stack we need to make sure offsets of pointers are known at translation time (for now) and perform correct load/mask/shift operations. Since we can access first 64B of LMEM without much effort support only stacks not bigger than 64B. Following commits will extend the possible sizes beyond that.

|\| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were quite a few overlapping sets of changes here. Daniel's bug fix for off-by-ones in the new BPF branch instructions, along with the added allowances for "data_end > ptr + x" forms collided with the metadata additions. Along with those three changes came veritifer test cases, which in their final form I tried to group together properly. If I had just trimmed GIT's conflict tags as-is, this would have split up the meta tests unnecessarily. In the socketmap code, a set of preemption disabling changes overlapped with the rename of bpf_compute_data_end() to bpf_compute_data_pointers(). Changes were made to the mv88e6060.c driver set addr method which got removed in net-next. The hyperv transport socket layer had a locking change in 'net' which overlapped with a change of socket state macro usage in 'net-next'. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | Move the software reg helpers and some static data to nfp_asm.c. They are related to the previous patch, but move is done in a separate commit for ease of review.

| | | | | | | | | | | | | | | | | | | | | | | | Define a new __bitwise type for software representation of registers. This will allow us to catch incorrect parameter types using sparse. Accessors we define also allow us to return correct enum type and therefore ensure all switches handle all register types.
