2022-04-08crypto: cavium/nitrox - remove check of list iterator against head past the loop bodyJakob Koschel1-4/+6
When list_for_each_entry() completes the iteration over the whole list without breaking the loop, the iterator value will be a bogus pointer computed based on the head element. While it is safe to use the pointer to determine if it was computed based on the head element, either with list_entry_is_head() or &pos->member == head, using the iterator variable after the loop should be avoided. In preparation to limit the scope of a list iterator to the list traversal loop, use a dedicated pointer to point to the found element [1].

2022-04-08crypto: ccp - When TSME and SME both detected notify userMario Limonciello1-0/+6
CC_ATTR_HOST_MEM_ENCRYPT is used to relay that memory encryption has been activated by the kernel. As it's technically possible to enable both SME and TSME at the same time, detect this scenario and notify the user that enabling TSME and SME at the same time is unnecessary.

2022-04-08crypto: ccp - Allow PSP driver to load without SEV/TEE supportMario Limonciello1-16/+0
Previously the PSP probe routine would fail if both SEV and TEE were missing. This is possibly the case for some client parts. As capabilities can now be accessed from userspace, it may still be useful to have the PSP driver finish loading so that those capabilities can be read.

2022-04-08crypto: testmgr - test in-place en/decryption with two sglistsEric Biggers1-12/+63
As was established in the thread https://lore.kernel.org/linux-crypto/20220223080400.139367-1-gilad@benyossef.com/T/#u, many crypto API users doing in-place en/decryption don't use the same scatterlist pointers for the source and destination, but rather use separate scatterlists that point to the same memory. This case isn't tested by the self-tests, resulting in bugs. This is the natural usage of the crypto API in some cases, so requiring API users to avoid this usage is not reasonable. Therefore, update the self-tests to start testing this case. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2022-04-08crypto: arm64/sm4 - add ARMv8 NEON implementationTianjia Zhang4-0/+938
This adds ARMv8 NEON implementations of SM4 in ECB, CBC, CFB and CTR modes. This implementation uses the plain NEON instruction set, All S-BOX substitutions uses the tbl/tbx instructions of ARMv8, combined with the out-of-order execution in CPU, this optimization supports encryption of up to 8 blocks at the same time. The performance of encrypting one block is not as good as software implementation, so the encryption operations of CBC and CFB still use pure software algorithms.

2022-04-08crypto: arm64/sm4-ce - rename to sm4-ce-cipherTianjia Zhang3-3/+3
The subsequent patches of the series will have an implementation of SM4-ECB/CBC/CFB/CTR accelerated by the CE instruction set, which conflicts with the current module name. In order to keep the naming rules of the AES algorithm consistent, the sm4-ce algorithm is renamed to sm4-ce-cipher. In addition, the speed of sm4-ce-cipher is better than that of SM4 NEON. By the way, the priority of the algorithm is adjusted to 300, which is also to leave room for the priority of SM4 NEON.

2022-04-07qed: remove an unneed NULL check on list iteratorXiaomeng Tong1-2/+2
The define for_each_pci_dev(d) is: while ((d = pci_get_device(PCI_ANY_ID, PCI_ANY_ID, d)) != NULL) Thus, the list iterator 'd' is always non-NULL so it doesn't need to be checked. So just remove the unnecessary NULL check. Also remove the unnecessary initializer because the list iterator is always initialized.

Even if an IOMMU might be present for some PCI segment in the system, that doesn't necessarily mean it provides translation for the device we care about. It appears that what we care about here is specifically whether DMA mapping ops involve any IOMMU overhead or not, so check for translation actually being active for our device.

That describes this case, so set the default for the devices here to NET_NAME_ENUM.

2022-04-07libbpf: Make BPF-side of USDT support work on big-endian machinesIlya Leoshkevich1-0/+3
BPF_USDT_ARG_REG_DEREF handling always reads 8 bytes, regardless of the actual argument size. On little-endian the relevant argument bits end up in the lower bits of val, and later on the code that handles all the argument types expects them to be there. On big-endian they end up in the upper bits of val, breaking that expectation. Fix by right-shifting val on big-endian.

Increment rx_otherhost_dropped counter when packet dropped due to mismatched dest MAC addr. An example when this drop can occur is when manually crafting raw packets that will be consumed by a user space application via a tap device. For testing purposes local traffic was generated using trafgen for the client and netcat to start a server Tested: Created 2 netns, sent 1 packet using trafgen from 1 to the other with "{eth(daddr=$INCORRECT_MAC...}", verified that iproute2 showed the counter was incremented. (Also had to modify iproute2 to show the stat, additional patch for that coming next.)

2022-04-07net: extract a few internals from netdevice.hJakub Kicinski11-70/+108
There's a number of functions and static variables used under net/core/ but not from the outside. We currently dump most of them into netdevice.h. That bad for many reasons: - netdevice.h is very cluttered, hard to figure out what the APIs are; - netdevice.h is very long; - we have to touch netdevice.h more which causes expensive incremental builds. Create a header under net/core/ and move some declarations. The new header is also a bit of a catch-all but that's fine, if we create more specific headers people will likely over-think where their declaration fit best. And end up putting them in netdevice.h, again. More work should be done on splitting netdevice.h into more targeted headers, but that'd be more time consuming so small steps.

2022-04-07soc: qcom: pdr: replace usage of found with dedicated list iterator variableJakob Koschel1-6/+5
To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean [1]. This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.
