crypto: Enable context analysis

2026-01-05T15:43:36+00:00

Enable context analysis for crypto subsystem. This demonstrates a larger conversion to use Clang's context analysis. The benefit is additional static checking of locking rules, along with better documentation. Note the use of the __acquire_ret macro how to define an API where a function returns a pointer to an object (struct scomp_scratch) with a lock held. Additionally, the analysis only resolves aliases where the analysis unambiguously sees that a variable was not reassigned after initialization, requiring minor code changes.

crypto: remove obsolete 'comp' compression API

2025-03-21T09:39:06+00:00

The 'comp' compression API has been superseded by the acomp API, which is a bit more cumbersome to use, but ultimately more flexible when it comes to hardware implementations. Now that all the users and implementations have been removed, let's remove the core plumbing of the 'comp' API as well. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: proc - Use str_yes_no() and str_no_yes() helpers

Remove hard-coded strings by using the str_yes_no() and str_no_yes() helpers. Remove unnecessary curly braces. Signed-off-by: Thorsten Blum Signed-off-by: Herbert Xu

crypto: proc - Print fips status

As FIPS may disable algorithms it is useful to show their status in /proc/crypto. Signed-off-by: Herbert Xu Acked-by: Ard Biesheuvel Signed-off-by: Herbert Xu

proc: introduce proc_create_seq{,_data}

2018-05-16T05:23:35+00:00

Variants of proc_create{,_data} that directly take a struct seq_operations argument and drastically reduces the boilerplate code in the callers. All trivial callers converted over. Signed-off-by: Christoph Hellwig

crypto: algapi - convert cra_refcnt to refcount_t

2018-01-05T07:43:09+00:00

Reference counters should use refcount_t rather than atomic_t, since the refcount_t implementation can prevent overflows, reducing the exploitability of reference leak bugs. crypto_alg.cra_refcount is a reference counter with the usual semantics, so switch it over to refcount_t.

crypto: fips - Move fips_enabled sysctl into fips.c

2015-04-23T06:18:09+00:00

There is currently a large ifdef FIPS code section in proc.c. Ostensibly it's there because the fips_enabled sysctl sits under /proc/sys/crypto. However, no other crypto sysctls exist. In fact, the whole ethos of the crypto API is against such user interfaces so this patch moves all the FIPS sysctl code over to fips.c. Signed-off-by: Herbert Xu
