MIPS: eBPF: Fix icache flush end address

2019-03-01T23:04:15Z

The MIPS eBPF JIT calls flush_icache_range() in order to ensure the icache observes the code that we just wrote. Unfortunately it gets the end address calculation wrong due to some bad pointer arithmetic. The struct jit_ctx target field is of type pointer to u32, and as such adding one to it will increment the address being pointed to by 4 bytes. Therefore in order to find the address of the end of the code we simply need to add the number of 4 byte instructions emitted, but we mistakenly add the number of instructions multiplied by 4. This results in the call to flush_icache_range() operating on a memory region 4x larger than intended, which is always wasteful and can cause crashes if we overrun into an unmapped page. Fix this by correcting the pointer arithmetic to remove the bogus multiplication, and use braces to remove the need for a set of brackets whilst also making it obvious that the target field is a pointer.

x86/hyper-v: Fix definition of HV_MAX_FLUSH_REP_COUNT

2019-02-28T10:58:29Z

The max flush rep count of HvFlushGuestPhysicalAddressList hypercall is equal with how many entries of union hv_gpa_page_range can be populated into the input parameter page. The code lacks parenthesis around PAGE_SIZE - 2 * sizeof(u64) which results in bogus computations. Add them.

crypto: arm64/chacha - fix hchacha_block_neon() for big endian

2019-02-28T06:37:48Z

On big endian arm64 kernels, the xchacha20-neon and xchacha12-neon self-tests fail because hchacha_block_neon() outputs little endian words but the C code expects native endianness. Fix it to output the words in native endianness (which also makes it match the arm32 version).
