Subject: [PATCH] selinux policy: allow custodia to access /proc/cpuinfo
|
|
|
|
On aarch64, custodia creates AVC when accessing /proc/cpuinfo.
|
|
|
|
According to gcrypt manual
|
|
(https://gnupg.org/documentation/manuals/gcrypt/Configuration.html),
|
|
/proc/cpuinfo is used on ARM architecture to read the hardware
|
|
capabilities of the CPU. This explains why the issue happens only
|
|
on aarch64.
|
|
|
|
audit2allow suggests to add the following:
|
|
allow ipa_custodia_t proc_t:file { getattr open read };
|
|
|
|
but this policy would be too broad. Instead, the patch is using
|
|
the interface kernel_read_system_state.
|
|
