2019-05-30crypto: echainiv - change to 'default n'Eric Biggers
echainiv is the only algorithm or template in the crypto API that is enabled by default. But there doesn't seem to be a good reason for it. And it pulls in a lot of stuff as dependencies, like AEAD support and a "NIST SP800-90A DRBG" including HMAC-SHA256. The commit which made it default 'm', commit 3491244c6298 ("crypto: echainiv - Set Kconfig default to m"), mentioned that it's needed for IPsec. However, later commit 32b6170ca59c ("ipv4+ipv6: Make INET*_ESP select CRYPTO_ECHAINIV") made the IPsec kconfig options select it. So, remove the 'default m'.

2019-05-30crypto: testmgr - make extra tests depend on cryptomgrEric Biggers
The crypto self-tests are part of the "cryptomgr" module, which can technically be disabled (though it rarely is). If you do so, currently you can still enable CRYPTO_MANAGER_EXTRA_TESTS, which doesn't make sense since in that case testmgr.c isn't compiled at all. Fix it by making it CRYPTO_MANAGER_EXTRA_TESTS depend on CRYPTO_MANAGER2, like CRYPTO_MANAGER_DISABLE_TESTS already does.

2019-05-30crypto: testmgr - fix length truncation with large page sizeEric Biggers
On PowerPC with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y, there is sometimes a crash in generate_random_aead_testvec(). The problem is that the generated test vectors use data lengths of up to about 2 * PAGE_SIZE, which is 128 KiB on PowerPC; however, the data length fields in the test vectors are 'unsigned short', so the lengths get truncated. Fix this by changing the relevant fields to 'unsigned int'.

2019-05-23crypto: drbg - add FIPS 140-2 CTRNG for noise sourceStephan Mueller
FIPS 140-2 section 4.9.2 requires a continuous self test of the noise source. Up to kernel 4.8 drivers/char/random.c provided this continuous self test. Afterwards it was moved to a location that is inconsistent with the FIPS 140-2 requirements. The relevant patch was e192be9d9a30555aae2ca1dc3aad37cba484cd4a . Thus, the FIPS 140-2 CTRNG is added to the DRBG when it obtains the seed. This patch resurrects the function drbg_fips_continous_test that existed some time ago and applies it to the noise sources. The patch that removed the drbg_fips_continous_test was b3614763059b82c26bdd02ffcb1c016c1132aad0 . The Jitter RNG implements its own FIPS 140-2 self test and thus does not need to be subjected to the test in the DRBG. The patch contains a tiny fix to ensure proper zeroization in case of an error during the Jitter RNG data gathering.

Currently there is a mismatch b/w the ICID (Isolation Context ID) used for DMA mapping keys and ICID used for accessing them. -keys are DMA mapped using a job ring device, thus a job ring ICID -keys are accessed from descriptors enqueued via Queue Interface, thus using QI ICID [Note: ICIDs of JRs, QI are configured by U-boot / other entity by: -fixing up the corresponding job ring and controller DT nodes -setting up corresponding caam ICID registers] In order to avoid IOMMU faults, DMA map the key using the controller device instead of a job ring device.

2019-05-23crypto: caam - convert top level drivers to librariesHoria Geantă
Currently we allow top level code, i.e. that which sits between the low level (HW-specific) drivers and crypto API, to be built as several drivers: caamalg, caamhash, caam_pkc, caamrng, caamalg_qi. There is no advantage in this, more it interferes with adding support for deferred probing (there are no corresponding devices and thus no bus). Convert these drivers and call init() / exit() manually at the right time. Move algorithms initialization at JR probe / remove time: -the first probed JR registers the crypto algs -the last removed JR unregisters the crypto algs Note: caam_qi_init() is called before JR platform devices creation (of_populate_bus()), such that QI interface is initialized when the caam/qi algorithms are registered in the JR driver (by calling caam_qi_algapi_init().

2019-05-23crypto: caam - fix S/G table passing page boundaryHoria Geantă
According to CAAM RM: -crypto engine reads 4 S/G entries (64 bytes) at a time, even if the S/G table has fewer entries -it's the responsibility of the user / programmer to make sure this HW behaviour has no side effect The drivers do not take care of this currently, leading to IOMMU faults when the S/G table ends close to a page boundary - since only one page is DMA mapped, while CAAM's DMA engine accesses two pages. Fix this by rounding up the number of allocated S/G table entries to a multiple of 4. Note that in case of two *contiguous* S/G tables, only the last table might needs extra entries.

2019-05-23crypto: caam - avoid S/G table fetching for AEAD zero-length outputHoria Geantă
When enabling IOMMU support, the following issue becomes visible in the AEAD zero-length case. Even though the output sequence length is set to zero, the crypto engine tries to prefetch 4 S/G table entries (since SGF bit is set in SEQ OUT PTR command - which is either generated in SW in case of caam/jr or in HW in case of caam/qi, caam/qi2). The DMA read operation will trigger an IOMMU fault since the address in the SEQ OUT PTR is "dummy" (set to zero / not obtained via DMA API mapping). 1. In case of caam/jr, avoid the IOMMU fault by clearing the SGF bit in SEQ OUT PTR command. 2. In case of caam/qi - setting address, bpid, length to zero for output entry in the compound frame has a special meaning (cf. CAAM RM): "Output frame = Unspecified, Input address = Y. A unspecified frame is indicated by an unused SGT entry (an entry in which the Address, Length, and BPID fields are all zero). SEC obtains output buffers from BMan as prescribed by the preheader." Since no output buffers are needed, modify the preheader by setting (ABS = 1, ADDBUF = 0): -"ABS = 1 means obtain the number of buffers in ADDBUF (0 or 1) from the pool POOL ID" -ADDBUF: "If ABS is set, ADD BUF specifies whether to allocate a buffer or not" 3. In case of caam/qi2, since engine: -does not support FLE[FMT]=2'b11 ("unused" entry) mentioned in DPAA2 RM -requires output entry to be present, even if not used the solution chosen is to leave output frame list entry zeroized.

We can already do this with --per-core, but it's often useful to do this together with other metrics that are collected per hardware thread. I.e. now its possible to do this per-event, and have it mixed with other events not aggregated by core. arm64: - Map Brahma-B53 CPUID to cortex-a53 events. - Add Cortex-A57 and Cortex-A72 events. csky: - Add DWARF register mappings for libdw, allowing --call-graph=dwarf to work on the C-SKY arch. x86: - Add support for recording and printing XMM registers, available, for instance, on Icelake. - Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON support.
