Richard Henderson	a8df33c37c	target/arm: Put all PAC keys into a structure ... This allows us to use a single syscall to initialize them all. Backports commit 108b3ba891408c4dce93df78261ec4aca38c0e2e from qemu	2019-05-23 14:54:06 -04:00
Richard Henderson	d633a04e61	target/arm: Implement pauth_computepac ... This is the main crypto routine, an implementation of QARMA. This matches, as much as possible, ARM pseudocode. Backports commit 990870b205ddfdba3fd3c1321e6083005ef59d1a from qemu	2019-01-22 16:35:07 -05:00
Richard Henderson	e23d1ef408	target/arm: Implement pauth_addpac ... This is not really functional yet, because the crypto is not yet implemented. This, however follows the AddPAC pseudo function. Backports commit 63ff0ca94cb84764d2aee45b37c5502a54811dab from qemu	2019-01-22 16:33:25 -05:00
Richard Henderson	4281ae11c4	target/arm: Implement pauth_auth ... This is not really functional yet, because the crypto is not yet implemented. This, however follows the Auth pseudo function. Backports commit a7bfa086c973a51fc18116c9d2e22a0e0069edba from qemu	2019-01-22 16:32:19 -05:00
Richard Henderson	2545f8cf84	target/arm: Implement pauth_strip ... Stripping out the authentication data does not require any crypto, it merely requires the virtual address parameters. Backports commit 04d13549fa10bb9775a90701e4e6fd0a2cbf83cb from qemu	2019-01-22 16:31:11 -05:00
Richard Henderson	e6196b2040	target/arm: Add PAuth helpers ... The cryptographic internals are stubbed out for now, but the enable and trap bits are checked. Backports commit 0d43e1a2d29a05f7b0d5629caaff18733cbdf3bb from qemu	2019-01-22 15:27:15 -05:00
