crypto: tcrypt - avoid mapping from module image addresses The output buffer in test_ahash_speed will point to an address located within the tcrypt module image. This causes problems when trying to DMA map the buffer. For e.g. on ARM-based LS1021A, a page fault occurs within the DMA API when trying to access the struct page returned by virt_to_page(output): insmod tcrypt.ko mode=403 testing speed of async sha1 (sha1-caam) test 0 ( 16 byte blocks, 16 bytes per update, 1 updates): Unable to handle kernel paging request at virtual address f07e9080 pgd = e58d0e00 [f07e9080] *pgd=80000080007003, *pmd=00000000 Internal error: Oops: 206 [#1] SMP THUMB2 Modules linked in: tcrypt(+) CPU: 1 PID: 1119 Comm: insmod Not tainted 4.2.0-rc1-256134-gbf433416e675 #1 Hardware name: Freescale LS1021A task: ea063900 ti: e5a34000 task.ti: e5a34000 PC is at dma_cache_maint_page+0x38/0xd0 LR is at __dma_page_cpu_to_dev+0x15/0x64 pc : [<800155a0>] lr : [<8001564d>] psr: 000f0033 sp : e5a35ca0 ip : 8063df00 fp : f07e9080 r10: 00000cd0 r9 : 8063df00 r8 : 805a2f04 r7 : 0017f804 r6 : 00000002 r5 : ee7f9000 r4 : 00000014 r3 : 80612d40 r2 : 01ff0080 r1 : 00000380 r0 : ee7f9000 Flags: nzcv IRQs on FIQs on Mode SVC_32 ISA Thumb Segment user Control: 70c5387d Table: e58d0e00 DAC: 9b7ede70 Process insmod (pid: 1119, stack limit = 0xe5a34210) Stack: (0xe5a35ca0 to 0xe5a36000) [...] [<800155a0>] (dma_cache_maint_page) from [<8001564d>] (__dma_page_cpu_to_dev+0x15/0x64) [<8001564d>] (__dma_page_cpu_to_dev) from [<800156eb>] (arm_dma_map_page+0x1f/0x44) [<800156eb>] (arm_dma_map_page) from [<802935e3>] (ahash_digest+0x35f/0x510) [<802935e3>] (ahash_digest) from [<7f800d03>] (test_ahash_speed.constprop.6+0x24a/0x4e4 [tcrypt]) [<7f800d03>] (test_ahash_speed.constprop.6 [tcrypt]) from [<7f802fd5>] (do_test+0x1898/0x2058 [tcrypt]) [<7f802fd5>] (do_test [tcrypt]) from [<7f80802f>] (tcrypt_mod_init+0x2e/0x63 [tcrypt]) [<7f80802f>] (tcrypt_mod_init [tcrypt]) from [<80009517>] (do_one_initcall+0xb3/0x134) [<80009517>] (do_one_initcall) from [<80351ec7>] (do_init_module+0x3b/0x13c) [<80351ec7>] (do_init_module) from [<8005cc3f>] (load_module+0x97b/0x9dc) [<8005cc3f>] (load_module) from [<8005cd8d>] (SyS_finit_module+0x35/0x3e) [<8005cd8d>] (SyS_finit_module) from [<8000d101>] (ret_fast_syscall+0x1/0x4c) Code: 1aba 0152 eb00 0b02 (5882) 0f92 addr2line -f -i -e vmlinux 800155a0 page_zonenum include/linux/mm.h:728 page_zone include/linux/mm.h:881 dma_cache_maint_page arch/arm/mm/dma-mapping.c:822 Signed-off-by: Horia Geant? <horia.geanta@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

For e.g. on ARM-based LS1021A, a page fault occurs within the DMA API when trying to access the struct page returned by virt_to_page(output): insmod tcrypt.ko mode=403 testing speed of async sha1 (sha1-caam) test 0 ( 16 byte blocks, 16 bytes per update, 1 updates): Unable to handle kernel paging request at virtual address f07e9080 pgd = e58d0e00 [f07e9080] *pgd=80000080007003, *pmd=00000000 Internal error: Oops: 206 [#1] SMP THUMB2 Modules linked in: tcrypt(+) CPU: 1 PID: 1119 Comm: insmod Not tainted 4.2.0-rc1-256134-gbf433416e675 #1 Hardware name: Freescale LS1021A task: ea063900 ti: e5a34000 task.ti: e5a34000 PC is at dma_cache_maint_page+0x38/0xd0 LR is at __dma_page_cpu_to_dev+0x15/0x64 pc : [<800155a0>] lr : [<8001564d>] psr: 000f0033 sp : e5a35ca0 ip : 8063df00 fp : f07e9080 r10: 00000cd0 r9 : 8063df00 r8 : 805a2f04 r7 : 0017f804 r6 : 00000002 r5 : ee7f9000 r4 : 00000014 r3 : 80612d40 r2 : 01ff0080 r1 : 00000380 r0 : ee7f9000 Flags: nzcv IRQs on FIQs on Mode SVC_32 ISA Thumb Segment user Control: 70c5387d Table: e58d0e00 DAC: 9b7ede70 Process insmod (pid: 1119, stack limit = 0xe5a34210) Stack: (0xe5a35ca0 to 0xe5a36000) [...] [<800155a0>] (dma_cache_maint_page) from [<8001564d>] (__dma_page_cpu_to_dev+0x15/0x64) [<8001564d>] (__dma_page_cpu_to_dev) from [<800156eb>] (arm_dma_map_page+0x1f/0x44) [<800156eb>] (arm_dma_map_page) from [<802935e3>] (ahash_digest+0x35f/0x510) [<802935e3>] (ahash_digest) from [<7f800d03>] (test_ahash_speed.constprop.6+0x24a/0x4e4 [tcrypt]) [<7f800d03>] (test_ahash_speed.constprop.6 [tcrypt]) from [<7f802fd5>] (do_test+0x1898/0x2058 [tcrypt]) [<7f802fd5>] (do_test [tcrypt]) from [<7f80802f>] (tcrypt_mod_init+0x2e/0x63 [tcrypt]) [<7f80802f>] (tcrypt_mod_init [tcrypt]) from [<80009517>] (do_one_initcall+0xb3/0x134) [<80009517>] (do_one_initcall) from [<80351ec7>] (do_init_module+0x3b/0x13c) [<80351ec7>] (do_init_module) from [<8005cc3f>] (load_module+0x97b/0x9dc) [<8005cc3f>] (load_module) from [<8005cd8d>] (SyS_finit_module+0x35/0x3e) [<8005cd8d>] (SyS_finit_module) from [<8000d101>] (ret_fast_syscall+0x1/0x4c) Code: 1aba 0152 eb00 0b02 (5882) 0f92 addr2line -f -i -e vmlinux 800155a0 page_zonenum include/linux/mm.h:728 page_zone include/linux/mm.h:881 dma_cache_maint_page arch/arm/mm/dma-mapping.c:822 Signed-off-by: Horia Geant? <horia.geanta@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: tcrypt - fix uninit sg entries in test_acipher_speed Commit 5be4d4c94b1f ("crypto: replace scatterwalk_sg_next with sg_next") did not consider the fact that scatterwalk_sg_next() was looking at sg entry length, while sg_next() looks at the "chained" sg bit. This should have no effect in theory. However in practice, there are cases where the sg table is initialized to a number of entries and some of them are not properly configured. While scatterwalk_sg_next() would have returned NULL (since sg length = 0 and sg page_link = 0), sg_next() happily returns the next unconfigured sg entry. insmod tcrypt.ko mode=500 sec=1 testing speed of async cbc(aes) (cbc-aes-talitos) encryption test 0 (128 bit key, 16 byte blocks): Unable to handle kernel paging request for data at address 0x00000000 Faulting instruction address: 0xc00d79e4 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=8 P1022 DS Modules linked in: tcrypt(+) talitos CPU: 0 PID: 2670 Comm: insmod Not tainted 4.0.0-rc1-QorIQ-SDK-V1.6+g904f1ca82209 #1 task: e8de3200 ti: e70bc000 task.ti: e70bc000 NIP: c00d79e4 LR: f92d223c CTR: c00d79c8 REGS: e70bda00 TRAP: 0300 Not tainted (4.0.0-rc1-QorIQ-SDK-V1.6+g904f1ca82209) MSR: 00029000 <CE,EE,ME> CR: 84428f22 XER: 00000000 DEAR: 00000000 ESR: 00000000 GPR00: f92d223c e70bdab0 e8de3200 00000000 e70bdbb8 00000001 00000000 00000000 GPR08: 00000000 00000000 c08b0380 27282010 c00d79c8 1003a634 00000000 e70bdf1c GPR16: e70bdef0 00000020 00000000 c08c0000 00000010 00000000 e70bdbb8 00000010 GPR24: e976d3a8 00000010 00000000 e70bdbd8 e8961010 00000001 c086e560 00000000 NIP [c00d79e4] page_address+0x1c/0x110 LR [f92d223c] talitos_map_sg+0x130/0x184 [talitos] Call Trace: [e70bdab0] [00000010] 0x10 (unreliable) [e70bdad0] [f92d223c] talitos_map_sg+0x130/0x184 [talitos] [e70bdb00] [f92d30d8] common_nonsnoop.constprop.13+0xc0/0x304 [talitos] [e70bdb30] [f933fd90] test_acipher_speed+0x434/0x7dc [tcrypt] [e70bdcc0] [f934318c] do_test+0x2478/0x306c [tcrypt] [e70bdd80] [f11fe058] tcrypt_mod_init+0x58/0x100 [tcrypt] [e70bdda0] [c0002354] do_one_initcall+0x90/0x1f4 [e70bde10] [c061fe00] do_init_module+0x60/0x1ac [e70bde30] [c00a79f0] load_module+0x185c/0x1f88 [e70bdee0] [c00a82b0] SyS_finit_module+0x7c/0x98 [e70bdf40] [c000e8b0] ret_from_syscall+0x0/0x3c Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: api - allow algs only in specific constructions in FIPS mode Currently we do not distinguish between algorithms that fail on the self-test vs. those which are disabled in FIPS mode (not allowed). Both are marked as having failed the self-test. Recently the need arose to allow the usage of certain algorithms only as arguments to specific template instantiations in FIPS mode. For example, standalone "dh" must be blocked, but e.g. "ffdhe2048(dh)" is allowed. Other potential use cases include "cbcmac(aes)", which must only be used with ccm(), or "ghash", which must be used only for gcm(). This patch allows this scenario by adding a new flag FIPS_INTERNAL to indicate those algorithms that are not FIPS-allowed. They can then be used as template arguments only, i.e. when looked up via crypto_grab_spawn() to be more specific. The FIPS_INTERNAL bit gets propagated upwards recursively into the surrounding template instances, until the construction eventually matches an explicit testmgr entry with ->fips_allowed being set, if any. The behaviour to skip !->fips_allowed self-test executions in FIPS mode will be retained. Note that this effectively means that FIPS_INTERNAL algorithms are handled very similarly to the INTERNAL ones in this regard. It is expected that the FIPS_INTERNAL algorithms will receive sufficient testing when the larger constructions they're a part of, if any, get exercised by testmgr. Note that as a side-effect of this patch algorithms which are not FIPS-allowed will now return ENOENT instead of ELIBBAD. Hopefully this is not an issue as some people were relying on this already.

crypto: adiantum - add Adiantum support Add support for the Adiantum encryption mode. Adiantum was designed by Paul Crowley and is specified by our paper: Adiantum: length-preserving encryption for entry-level processors (https://eprint.iacr.org/2018/720.pdf) See our paper for full details; this patch only provides an overview. Adiantum is a tweakable, length-preserving encryption mode designed for fast and secure disk encryption, especially on CPUs without dedicated crypto instructions. Adiantum encrypts each sector using the XChaCha12 stream cipher, two passes of an ε-almost-∆-universal (εA∆U) hash function, and an invocation of the AES-256 block cipher on a single 16-byte block. On CPUs without AES instructions, Adiantum is much faster than AES-XTS; for example, on ARM Cortex-A7, on 4096-byte sectors Adiantum encryption is about 4 times faster than AES-256-XTS encryption, and decryption about 5 times faster. Adiantum is a specialization of the more general HBSH construction. Our earlier proposal, HPolyC, was also a HBSH specialization, but it used a different εA∆U hash function, one based on Poly1305 only. Adiantum's εA∆U hash function, which is based primarily on the "NH" hash function like that used in UMAC (RFC4418), is about twice as fast as HPolyC's; consequently, Adiantum is about 20% faster than HPolyC. This speed comes with no loss of security: Adiantum is provably just as secure as HPolyC, in fact slightly *more* secure. Like HPolyC, Adiantum's security is reducible to that of XChaCha12 and AES-256, subject to a security bound. XChaCha12 itself has a security reduction to ChaCha12. Therefore, one need not "trust" Adiantum; one need only trust ChaCha12 and AES-256. Note that the εA∆U hash function is only used for its proven combinatorical properties so cannot be "broken". Adiantum is also a true wide-block encryption mode, so flipping any plaintext bit in the sector scrambles the entire ciphertext, and vice versa. No other such mode is available in the kernel currently; doing the same with XTS scrambles only 16 bytes. Adiantum also supports arbitrary-length tweaks and naturally supports any length input >= 16 bytes without needing "ciphertext stealing". For the stream cipher, Adiantum uses XChaCha12 rather than XChaCha20 in order to make encryption feasible on the widest range of devices. Although the 20-round variant is quite popular, the best known attacks on ChaCha are on only 7 rounds, so ChaCha12 still has a substantial security margin; in fact, larger than AES-256's. 12-round Salsa20 is also the eSTREAM recommendation. For the block cipher, Adiantum uses AES-256, despite it having a lower security margin than XChaCha12 and needing table lookups, due to AES's extensive adoption and analysis making it the obvious first choice. Nevertheless, for flexibility this patch also permits the "adiantum" template to be instantiated with XChaCha20 and/or with an alternate block cipher. We need Adiantum support in the kernel for use in dm-crypt and fscrypt, where currently the only other suitable options are block cipher modes such as AES-XTS. A big problem with this is that many low-end mobile devices (e.g. Android Go phones sold primarily in developing countries, as well as some smartwatches) still have CPUs that lack AES instructions, e.g. ARM Cortex-A7. Sadly, AES-XTS encryption is much too slow to be viable on these devices. We did find that some "lightweight" block ciphers are fast enough, but these suffer from problems such as not having much cryptanalysis or being too controversial. The ChaCha stream cipher has excellent performance but is insecure to use directly for disk encryption, since each sector's IV is reused each time it is overwritten. Even restricting the threat model to offline attacks only isn't enough, since modern flash storage devices don't guarantee that "overwrites" are really overwrites, due to wear-leveling. Adiantum avoids this problem by constructing a "tweakable super-pseudorandom permutation"; this is the strongest possible security model for length-preserving encryption. Of course, storing random nonces along with the ciphertext would be the ideal solution. But doing that with existing hardware and filesystems runs into major practical problems; in most cases it would require data journaling (like dm-integrity) which severely degrades performance. Thus, for now length-preserving encryption is still needed.

crypto: hctr2 - Add HCTR2 support Add support for HCTR2 as a template. HCTR2 is a length-preserving encryption mode that is efficient on processors with instructions to accelerate AES and carryless multiplication, e.g. x86 processors with AES-NI and CLMUL, and ARM processors with the ARMv8 Crypto Extensions. As a length-preserving encryption mode, HCTR2 is suitable for applications such as storage encryption where ciphertext expansion is not possible, and thus authenticated encryption cannot be used. Currently, such applications usually use XTS, or in some cases Adiantum. XTS has the disadvantage that it is a narrow-block mode: a bitflip will only change 16 bytes in the resulting ciphertext or plaintext. This reveals more information to an attacker than necessary. HCTR2 is a wide-block mode, so it provides a stronger security property: a bitflip will change the entire message. HCTR2 is somewhat similar to Adiantum, which is also a wide-block mode. However, HCTR2 is designed to take advantage of existing crypto instructions, while Adiantum targets devices without such hardware support. Adiantum is also designed with longer messages in mind, while HCTR2 is designed to be efficient even on short messages. HCTR2 requires POLYVAL and XCTR as components.

crypto: twofish - add x86_64/avx assembler implementation This patch adds a x86_64/avx assembler implementation of the Twofish block cipher. The implementation processes eight blocks in parallel (two 4 block chunk AVX operations). The table-lookups are done in general-purpose registers. For small blocksizes the 3way-parallel functions from the twofish-x86_64-3way module are called. A good performance increase is provided for blocksizes greater or equal to 128B. Patch has been tested with tcrypt and automated filesystem tests. Tcrypt benchmark results: Intel Core i5-2500 CPU (fam:6, model:42, step:7) twofish-avx-x86_64 vs. twofish-x86_64-3way 128bit key: (lrw:256bit) (xts:256bit) size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec lrw-enc lrw-dec xts-enc xts-dec 16B 0.96x 0.97x 1.00x 0.95x 0.97x 0.97x 0.96x 0.95x 0.95x 0.98x 64B 0.99x 0.99x 1.00x 0.99x 0.98x 0.98x 0.99x 0.98x 0.99x 0.98x 256B 1.20x 1.21x 1.00x 1.19x 1.15x 1.14x 1.19x 1.20x 1.18x 1.19x 1024B 1.29x 1.30x 1.00x 1.28x 1.23x 1.24x 1.26x 1.28x 1.26x 1.27x 8192B 1.31x 1.32x 1.00x 1.31x 1.25x 1.25x 1.28x 1.29x 1.28x 1.30x 256bit key: (lrw:384bit) (xts:512bit) size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec lrw-enc lrw-dec xts-enc xts-dec 16B 0.96x 0.96x 1.00x 0.96x 0.97x 0.98x 0.95x 0.95x 0.95x 0.96x 64B 1.00x 0.99x 1.00x 0.98x 0.98x 1.01x 0.98x 0.98x 0.98x 0.98x 256B 1.20x 1.21x 1.00x 1.21x 1.15x 1.15x 1.19x 1.20x 1.18x 1.19x 1024B 1.29x 1.30x 1.00x 1.28x 1.23x 1.23x 1.26x 1.27x 1.26x 1.27x 8192B 1.31x 1.33x 1.00x 1.31x 1.26x 1.26x 1.29x 1.29x 1.28x 1.30x twofish-avx-x86_64 vs aes-asm (8kB block): 128bit 256bit ecb-enc 1.19x 1.63x ecb-dec 1.18x 1.62x cbc-enc 0.75x 1.03x cbc-dec 1.23x 1.67x ctr-enc 1.24x 1.65x ctr-dec 1.24x 1.65x lrw-enc 1.15x 1.53x lrw-dec 1.14x 1.52x xts-enc 1.16x 1.56x xts-dec 1.16x 1.56x Signed-off-by: Johannes Goetzfried <Johannes.Goetzfried@informatik.stud.uni-erlangen.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
