These are now compiled with compiler CFI mitigations enabled. This does not apply to non-web-applets. This uses the crc32x instruction, and x18 as a previously-initialized constant.
These are now compiled with compiler Pointer Authentication / CFI mitigations enabled. This does not apply to non-web-applets.
 
Pointer Authentication uses the crc32x instruction, and x18 as a cryptographically-random u64 provided by the kernel. The only userland code using x18 is the mul instruction for this, nothing else (applies to all NSOs/NROs).
 
This is used to add/subtract x30 starting with bit40, during functions entry/exit. The code for entry/exit is identical, except that entry does add, and exit uses subtract:
* The low 40-bits of x30 are extracted, then multiplied with x18.
* <code>crc32x w17, wzr, x17</code> (which uses the above value)
* Then the previously mentioned add/subtraction operation is done, with the output from the above shifted to bit40.
 
The x18 is OR'd by kernel with 1, to make sure it is odd. This means that the multiply is a bijection; in other words, no entropy is lost when doing the multiply. If this had not been done, a random value that is divisible by a large power of two (the attacker can just keep spawning threads until gets such a one), would have weak cookies that allows the scheme to be trivially broken.
 
CFI is implemented as follows: blr instructions no longer exist. When funcptrs are called, new functions are now called instead which handles the call. The u32 at funcptr_addr-4 must match 0xe7ffdefe, otherwise it will branch to undefined instruction 0x0000dead. Otherwise, it will jump to the funcptr_addr.


This is used to add/subtract x30 starting with bit40, during functions entry/exit.
Almost all functions now have the above u32 at -4, therefore funcptr calls now have to start at the actual funcptr start. However, this doesn't apply to calls done during functions' exit: these directly br to the funcptr_addr without extra validation. The br instructions in the .plt were also replaced with branches to the function described above.

The above applies to all NSOs in ExeFs, except for LibraryAppletOfflineWeb which doesn't have it enabled. The NROs in the BrowserDll SystemData have it enabled for "/nro/netfront/dll_1/", however "dll_0" doesn't have it enabled (which is used by LibraryAppletOfflineWeb).

This is referred to in the build-path strings as "NX-NXFP2-a64-cfi" (nnSdkEmpty), and "NX64-cfi" (OSS).
