203a6763ab Revert "crypto: pkcs7 - remove sha1 support"
This reverts commit 16ab7cb582 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.

77292bb8ca crypto: scomp - remove memcpy if sg_nents is 1 and pages are lowmem
while sg_nents is 1, which is always true for the current kernel
as the only user - zswap is this case, we might have a chance to
remove memcpy, thus improve the performance.
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.

2beb81fbf0 crypto: remove CONFIG_CRYPTO_STATS
Remove support for the "Crypto usage statistics" feature
(CONFIG_CRYPTO_STATS).  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.

f66a211e8c crypto: dh - Make public key test FIPS-only
The function dh_is_pubkey_valid was added to for FIPS but it was
only partially conditional to fips_enabled.

In particular, the first test in the function relies on the last
test to work properly, but the last test is only run in FIPS mode.

Fix this inconsistency by making the whole function conditional
on fips_enabled.

The lskcipher glue code for skcipher needs to copy the IV every
time rather than only on the first and last request.  Otherwise
those algorithms that use IV to perform chaining may break, e.g.,
CBC.

This is because crypto_skcipher_import/export do not include the
IV as part of the saved state.

2947a4567f treewide: update LLVM Bugzilla links
LLVM moved their issue tracker from their own Bugzilla instance to GitHub
issues.  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.

e8829ef1f7 crypto: rsa - restrict plaintext/ciphertext values more
SP 800-56Br2, Section 7.1.1 [1] specifies that:
1. If m does not satisfy 1 < m < (n – 1), output an indication that m is
out of range, and exit without further processing.

Similarly, Section 7.1.2 of the same standard specifies that:
1. If the ciphertext c does not satisfy 1 < c < (n – 1), output an
indication that the ciphertext is out of range, and exit without further

2ec6761df8 crypto: iaa - Add support for deflate-iaa compression algorithm
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.

Park ]

99bd99d3e3 crypto: algif_skcipher - Fix stream cipher chaining
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.

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.

0ae4dcc1eb crypto: skcipher - Add internal state support
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.

a312e07a65 crypto: adiantum - flush destination page before unmapping
Upon additional review, the new fast path in adiantum_finish() is
missing the call to flush_dcache_page() that scatterwalk_map_and_copy()
was doing.  It's apparently debatable whether flush_dcache_page() is
actually needed, as per the discussion at
https://lore.kernel.org/lkml/YYP1lAq46NWzhOf0@casper.infradead.org/T/#u.
However, it appears that currently all the helper functions that write
to a page, such as scatterwalk_map_and_copy(), memcpy_to_page(), and
memzero_page(), do the dcache flush.  So do it to be consistent.

alg_test_descs[] needs to be in sorted order, since it is used for
binary search.  This fixes the following boot-time warning:

    testmgr: alg_test_descs entries in wrong order: 'pkcs1pad(rsa,sha512)' before 'pkcs1pad(rsa,sha3-256)'

b46503068c certs: Only allow certs signed by keys on the builtin keyring
Originally the secondary trusted keyring provided a keyring to which extra
keys may be added, provided those keys were not blacklisted and were
vouched for by a key built into the kernel or already in the secondary
trusted keyring.

On systems with the machine keyring configured, additional keys may also
be vouched for by a key on the machine keyring.

Prevent loading additional certificates directly onto the secondary
keyring, vouched for by keys on the machine keyring, yet allow these
certificates to be loaded onto other trusted keyrings.
