Mark O'Donovan	9e47a758b7	crypto: lib/mpi - avoid null pointer deref in mpi_cmp_ui() ... During NVMeTCP Authentication a controller can trigger a kernel oops by specifying the 8192 bit Diffie Hellman group and passing a correctly sized, but zeroed Diffie Hellamn value. mpi_cmp_ui() was detecting this if the second parameter was 0, but 1 is passed from dh_is_pubkey_valid(). This causes the null pointer u->d to be dereferenced towards the end of mpi_cmp_ui() Signed-off-by: Mark O'Donovan <shiftee@posteo.net> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2023-08-11 19:19:52 +08:00
Herbert Xu	2a598d0b28	crypto: lib - Move mpi into lib/crypto ... As lib/mpi is mostly used by crypto code, move it under lib/crypto so that patches touching it get directed to the right mailing list.
