Description:

This update for openCryptoki fixes the following issues

Security issue:

  • CVE-2026-40253: Updated fix for malformed BER-encoded cryptographic objects (bsc#1262283).

Non security issue:

  • Refactored .spec file to fully support transactional and immutable operating systems (jsc#PED-14609):
  • Migrated user and group creation (pkcs11, pkcsslotd) from imperative %pre shell commands to declarative systemd-sysusers configuration.
  • Replaced manual /var directory tracking and %ghost directives with comprehensive systemd-tmpfiles configurations.
  • Implemented dynamic, architecture-specific tmpfiles.d generation to properly provision hardware-specific token directories (e.g., ccatok, ep11tok, lite, and HSM_MK_CHANGE).
  • Fixed permissions for /run/opencryptoki within tmpfiles.d to ensure the daemon can successfully drop privileges and bind its communication socket.
  • Moved 32-bit and 64-bit shared library symlink creation (such as PKCS11_API.so, stdll, and methods) from %post scriptlets into the %install phase, ensuring they are correctly packaged and tracked on the read-only /usr partition.
  • Removed legacy /etc/pkcs11 bash migration logic from %post, replacing it with a declarative tmpfiles.d symlink rule.
  • Cleaned up scriptlets to only execute transaction-safe macros (such as ldconfig and systemd service handlers).
