* | net: add sk_wake_async_rcu() helperEric Dumazet2024-03-291-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | | While looking at UDP receive performance, I saw sk_wake_async() was no longer inlined. This matters at least on AMD Zen1-4 platforms (see SRSO) This might be because rcu_read_lock() and rcu_read_unlock() are no longer nops in recent kernels ? Add sk_wake_async_rcu() variant, which must be called from contexts already holding rcu lock. As SOCK_FASYNC is deprecated in modern days, use unlikely() to give a hint to the compiler. sk_wake_async_rcu() is properly inlined from __udp_enqueue_schedule_skb() and sock_def_readable().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 16ab7cb5825fc3425c16ad2c6e53d827f382d7c6 because it broke iwd. iwd uses the KEYCTL_PKEY_* UAPIs via its dependency libell, and apparently it is relying on SHA-1 signature support. These UAPIs are fairly obscure, and their documentation does not mention which algorithms they support. iwd really should be using a properly supported userspace crypto library instead. Regardless, since something broke we have to revert the change. It may be possible that some parts of this commit can be reinstated without breaking iwd (e.g. probably the removal of MODULE_SIG_SHA1), but for now this just does a full revert to get things working again.

Though sg_nents is 1, its buffer might cross two pages. If those pages are highmem, we have no cheap way to map them to contiguous virtual address because kmap doesn't support more than one page (kmap single higmem page could be still expensive for tlb) and vmap is expensive. So we also test and enure page is not highmem in order to safely use page_to_virt before removing the memcpy. The good news is that in the most majority of cases, we are lowmem, and we are always lowmem in those modern and popular hardware.

This feature does not appear to have ever been used, and it is harmful because it significantly reduces performance and is a large maintenance burden. Covering each of these points in detail: 1. Feature is not being used Since these generic crypto statistics are only readable using netlink, it's fairly straightforward to look for programs that use them. I'm unable to find any evidence that any such programs exist. For example, Debian Code Search returns no hits except the kernel header and kernel code itself and translations of the kernel header: https://codesearch.debian.net/search?q=CRYPTOCFGA_STAT&literal=1&perpkg=1 The patch series that added this feature in 2018 (https://lore.kernel.org/linux-crypto/1537351855-16618-1-git-send-email-clabbe@baylibre.com/) said "The goal is to have an ifconfig for crypto device." This doesn't appear to have happened. It's not clear that there is real demand for crypto statistics. Just because the kernel provides other types of statistics such as I/O and networking statistics and some people find those useful does not mean that crypto statistics are useful too. Further evidence that programs are not using CONFIG_CRYPTO_STATS is that it was able to be disabled in RHEL and Fedora as a bug fix (https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/2947). Even further evidence comes from the fact that there are and have been bugs in how the stats work, but they were never reported. For example, before Linux v6.7 hash stats were double-counted in most cases. There has also never been any documentation for this feature, so it might be hard to use even if someone wanted to. 2. CONFIG_CRYPTO_STATS significantly reduces performance Enabling CONFIG_CRYPTO_STATS significantly reduces the performance of the crypto API, even if no program ever retrieves the statistics. This primarily affects systems with large number of CPUs. For example, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2039576 reported that Lustre client encryption performance improved from 21.7GB/s to 48.2GB/s by disabling CONFIG_CRYPTO_STATS. It can be argued that this means that CONFIG_CRYPTO_STATS should be optimized with per-cpu counters similar to many of the networking counters. But no one has done this in 5+ years. This is consistent with the fact that the feature appears to be unused, so there seems to be little interest in improving it as opposed to just disabling it. It can be argued that because CONFIG_CRYPTO_STATS is off by default, performance doesn't matter. But Linux distros tend to error on the side of enabling options. The option is enabled in Ubuntu and Arch Linux, and until recently was enabled in RHEL and Fedora (see above). So, even just having the option available is harmful to users. 3. CONFIG_CRYPTO_STATS is a large maintenance burden There are over 1000 lines of code associated with CONFIG_CRYPTO_STATS, spread among 32 files. It significantly complicates much of the implementation of the crypto API. After the initial submission, many fixes and refactorings have consumed effort of multiple people to keep this feature "working". We should be spending this effort elsewhere.

While all of the links are still valid, they may not necessarily show the most up to date information around the issues, as all updates will occur on GitHub, not Bugzilla. Another complication is that the Bugzilla issue number is not always the same as the GitHub issue number. Thankfully, LLVM maintains this mapping through two shortlinks: https://llvm.org/bz<num> -> https://bugs.llvm.org/show_bug.cgi?id=<num> https://llvm.org/pr<num> -> https://github.com/llvm/llvm-project/issues/<mapped_num> Switch all "https://bugs.llvm.org/show_bug.cgi?id=<num>" links to the "https://llvm.org/pr<num>" shortlink so that the links show the most up to date information. Each migrated issue links back to the Bugzilla entry, so there should be no loss of fidelity of information here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch registers the deflate-iaa deflate compression algorithm and hooks it up to the IAA hardware using the 'fixed' compression mode introduced in the previous patch. Because the IAA hardware has a 4k history-window limitation, only buffers <= 4k, or that have been compressed using a <= 4k history window, are technically compliant with the deflate spec, which allows for a window of up to 32k. Because of this limitation, the IAA fixed mode deflate algorithm is given its own algorithm name, 'deflate-iaa'. With this change, the deflate-iaa crypto algorithm is registered and operational, and compression and decompression operations are fully enabled following the successful binding of the first IAA workqueue to the iaa_crypto sub-driver. when there are no IAA workqueues bound to the driver, the IAA crypto algorithm can be unregistered by removing the module. A new iaa_crypto 'verify_compress' driver attribute is also added, allowing the user to toggle compression verification. If set, each compress will be internally decompressed and the contents verified, returning error codes if unsuccessful. This can be toggled with 0/1: echo 0 > /sys/bus/dsa/drivers/crypto/verify_compress The default setting is '1' - verify all compresses. The verify_compress value setting at the time the algorithm is registered is captured in the algorithm's crypto_ctx and used for all compresses when using the algorithm.

* crypto: algif_skcipher - Fix stream cipher chainingHerbert Xu2023-12-081-3/+69
| | | | | | | | | | | | | | | | Unlike algif_aead which is always issued in one go (thus limiting the maximum size of the request), algif_skcipher has always allowed unlimited input data by cutting them up as necessary and feeding the fragments to the underlying algorithm one at a time. However, because of deficiencies in the API, this has been broken for most stream ciphers such as arc4 or chacha. This is because they have an internal state in addition to the IV that must be preserved in order to continue processing. Fix this by using the new skcipher state API.

* crypto: arc4 - Add internal stateHerbert Xu2023-12-081-1/+10
| | | | | | | | | | | | | The arc4 algorithm has always had internal state. It's been buggy from day one in that the state has been stored in the shared tfm object. That means two users sharing the same tfm will end up affecting each other's output, or worse, they may end up with the same output. Fix this by declaring an internal state and storing the state there instead of within the tfm context. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: skcipher - Make use of internal stateHerbert Xu2023-12-082-8/+106
| | | | | | | | | This patch adds code to the skcipher/lskcipher API to make use of the internal state if present. In particular, the skcipher lskcipher wrapper will allocate a buffer for the IV/state and feed that to the underlying lskcipher algorithm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: skcipher - Add internal state supportHerbert Xu2023-12-084-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike chaining modes such as CBC, stream ciphers other than CTR usually hold an internal state that must be preserved if the operation is to be done piecemeal. This has not been represented in the API, resulting in the inability to split up stream cipher operations. This patch adds the basic representation of an internal state to skcipher and lskcipher. In the interest of backwards compatibility, the default has been set such that existing users are assumed to be operating in one go as opposed to piecemeal. With the new API, each lskcipher/skcipher algorithm has a new attribute called statesize. For skcipher, this is the size of the buffer that can be exported or imported similar to ahash. For lskcipher, instead of providing a buffer of ivsize, the user now has to provide a buffer of ivsize + statesize. Each skcipher operation is assumed to be final as they are now, but this may be overridden with a request flag. When the override occurs, the user may then export the partial state and reimport it later. For lskcipher operations this is reversed. All operations are not final and the state will be exported unless the FINAL bit is set. However, the CONT bit still has to be set for the state to be used.
