Jeremy Linton 39e4716caa crypto: arm64: Use x16 with indirect branch to bti_c ... The AES code uses a 'br x7' as part of a function called by a macro. That branch needs a bti_j as a target. This results in a panic as seen below. Using x16 (or x17) with an indirect branch keeps the target bti_c. Bad mode in Synchronous Abort handler detected on CPU1, code 0x34000003 -- BTI CPU: 1 PID: 265 Comm: cryptomgr_test Not tainted 5.8.11-300.fc33.aarch64 #1 pstate: 20400c05 (nzCv daif +PAN -UAO BTYPE=j-) pc : aesbs_encrypt8+0x0/0x5f0 [aes_neon_bs] lr : aesbs_xts_encrypt+0x48/0xe0 [aes_neon_bs] sp : ffff80001052b730 aesbs_encrypt8+0x0/0x5f0 [aes_neon_bs] __xts_crypt+0xb0/0x2dc [aes_neon_bs] xts_encrypt+0x28/0x3c [aes_neon_bs] crypto_skcipher_encrypt+0x50/0x84 simd_skcipher_encrypt+0xc8/0xe0 crypto_skcipher_encrypt+0x50/0x84 test_skcipher_vec_cfg+0x224/0x5f0 test_skcipher+0xbc/0x120 alg_test_skcipher+0xa0/0x1b0 alg_test+0x3dc/0x47c cryptomgr_test+0x38/0x60 Fixes: 0e89640b64 ("crypto: arm64 - Use modern annotations for assembly functions") Cc: <stable@vger.kernel.org> # 5.6.x- Signed-off-by: Jeremy Linton <jeremy.linton@arm.com> Suggested-by: Dave P Martin <Dave.Martin@arm.com> Reviewed-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Mark Brown <broonie@kernel.org> Link: https://lore.kernel.org/r/20201006163326.2780619-1-jeremy.linton@arm.com Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>		2020-10-06 18:14:47 +01:00
