On systems with coherence issues, packet processed could succeed while it should have failed, e.g. because of an authentication fail. This is because the driver would read stale status information that had all error bits initialised to zero = no error. Since this is potential a security risk, we want to prevent it from being a possibility at all. So initialize all error bits to error state, so that reading stale status information will always result in errors. Signed-off-by:

This patch also fixes the incorrect endianness markings in the sun4i-ss driver. It should have no effect in the genereated code. Instead of using cpu_to_Xe32 followed by a memcpy, this patch converts the final hash write to use put_unaligned_X instead. Reported-by:

Herbert Xu authored
Since commit b56f5cbc ("crypto: arm/aes-neonbs - resolve fallback cipher at runtime") the CBC encryption path in aes-neonbs is now identical to that obtained through the cbc template. This means that it can simply call the generic cbc template instead of doing its own thing. This patch removes the custom encryption path and simply invokes the generic cbc template. Signed-off-by:

Cryptographic algorithms may have a lifespan that is significantly shorter than Linux's, and so we need to start phasing out algorithms that are known to be broken, and are no longer fit for general use. RC4 (or arc4) is a good example here: there are a few areas where its use is still somewhat acceptable, e.g., for interoperability with legacy wifi hardware that can only use WEP or TKIP data encryption, but that should not imply that, for instance, use of RC4 based EAP-TLS by the WPA supplicant for negotiating TKIP keys is equally acceptable, or that RC4 should remain available as a general purpose cryptographic transform for all in-kernel and user space clients. Now that all in-kernel users that need to retain support have moved to the arc4 library interface, and the known users of ecb(arc4) via the socket API (iwd [0] and libell [1][2]) have been updated to switch to a local implementation, we can take the next step, and mark the ecb(arc4) skcipher as obsolete, and only provide it if the socket API is enabled in the first place, as well as provide the option to disable all algorithms that have been marked as obsolete.

The RC4-HMAC-MD5 KerberosV algorithm is based on RFC 4757 [0], which was specifically issued for interoperability with Windows 2000, but was never intended to receive the same level of support. The RFC says The IETF Kerberos community supports publishing this specification as an informational document in order to describe this widely implemented technology. However, while these encryption types provide the operations necessary to implement the base Kerberos specification [RFC4120], they do not provide all the required operations in the Kerberos cryptography framework [RFC3961]. As a result, it is not generally possible to implement potential extensions to Kerberos using these encryption types. The Kerberos encryption type negotiation mechanism [RFC4537] provides one approach for using such extensions even when a Kerberos infrastructure uses long-term RC4 keys. Because this specification does not implement operations required by RFC 3961 and because of security concerns with the use of RC4 and MD4 discussed in Section 8, this specification is not appropriate for publication on the standards track. The RC4-HMAC encryption types are used to ease upgrade of existing Windows NT environments, provide strong cryptography (128-bit key lengths), and provide exportable (meet United States government export restriction requirements) encryption. This document describes the implementation of those encryption types. Furthermore, this RFC was re-classified as 'historic' by RFC 8429 [1] in 2018, stating that 'none of the encryption types it specifies should be used' Note that other outdated algorithms are left in place (some of which are guarded by CONFIG_SUNRPC_DISABLE_INSECURE_ENCTYPES), so this should only adversely affect interoperability with Windows NT/2000 systems that have not received any updates since 2008 (but are connected to a network nonetheless) [0] https://tools.ietf.org/html/rfc4757 [1] https://tools.ietf.org/html/rfc8429Signed-off-by:

The RNGB can generate 2^20 words (1 word == 4 byte) of 'random' data after the seed pool was initialized. The pool needs to be reseeded if more words are required. The reseeding is done automatically since commit 3acd9ea9 ("hwrng: imx-rngc - use automatic seeding"). We can't retrieve the TRNG values directly so we need a other way to get the quality level. We know that the PRNG uses 20.000 entropy samples from the TRNG to generate 2^20 words (1MiB) and the quality level is defined as (in bits of entropy per 1024 bits of input). So the quality level can be calculated by: 20.000 * 1024 ------------- = ~ 19.5 2^20 Signed-off-by:
