+ARM v8.3a pauth not working
+
+Host: Ubuntu 19.10 - x86_64 machine
+QEMU version: 3a63b24a1bbf166e6f455fe43a6bbd8dea413d92 (master)
+
+ARMV8.3 pauth is not working well.
+
+With a test code containing two pauth instructions:
+    - paciasp that sign LR with A key and sp as context;
+    - autiasp that verify the signature.
+
+Test:
+    - Run the program and corrupt LR just before autiasp (ex 0x3e00000400660 instead of 0x3e000000400664)
+
+Expected:
+    - autiasp places an invalid pointer in LR
+
+Result:
+    - autiasp successfully auth the pointer and places 0x0400660 in LR.
+
+Further explanations:
+    Adding traces in qemu code shows that "pauth_computepac" is not robust enough against truncating.
+    With 0x31000000400664 as input of pauth_auth, we obtain "0x55b1d65b2c138e14" for PAC, "0x30" for bot_bit and "0x38" for top_bit.
+    With 0x310040008743ec as input of pauth (with same key), we obtain "0x55b1d65b2c138ef4" for PAC, "0x30" for bot_bit and "0x38" for top_bit.
+    Values of top_bit and bottom_bit are strictly the same and it should not.
+
+Hi,
+
+Here is a patch for this bug. The sbox function was using "b+=16" instead of "b+=4".
+
+Also, you check test vector using :
+
+```c
+    uint64_t P = 0xfb623599da6e8127ull;
+    uint64_t T = 0x477d469dec0b8762ull;
+    uint64_t w0 = 0x84be85ce9804e94bull;
+    uint64_t k0 = 0xec2802d4e0a488e9ull;
+    ARMPACKey key = { .hi = w0, .lo = k0 };
+    uint64_t C5 = pauth_computepac(P, T, key);
+    /* C5 should be 0xc003b93999b33765 */
+```
+
+Ooof.  Good catch on the sbox error.
+
+That said, how did you test pauth_computepac?
+I still do not get the C5 result above, but 0x99d88f4472f3be39.
+
+The following test case sets up the parameters.
+
+Oops again.  The test case has the parts of the key the wrong way around.
+I'll submit the pair of patches to the mailing list.
+
+Now upstream as commit de0b1bae6461f67243282555475f88b2384a1eb9.
+
+Apparently this fixed bug is the official CVE-2020-10702:
