Background discussion is # covered here: https://lwn.net/Articles/751061/ # # - Implementation as an LSM, with a default stackable lockdown LSM # module. This allows the lockdown feature to be policy-driven, # rather than encoding an implicit policy within the mechanism. # # The new locked_down LSM hook is provided to allow LSMs to make a # policy decision around whether kernel functionality that would allow # tampering with or examining the runtime state of the kernel should be # permitted. # # The included lockdown LSM provides an implementation with a simple # policy intended for general purpose use. This policy provides a coarse # level of granularity, controllable via the kernel command line: # # lockdown={integrity\|confidentiality} # # Enable the kernel lockdown feature. If set to integrity, kernel features # that allow userland to modify the running kernel are disabled. If set to # confidentiality, kernel features that allow userland to extract # confidential information from the kernel are also disabled. # # This may also be controlled via /sys/kernel/security/lockdown and # overriden by kernel configuration. # # New or existing LSMs may implement finer-grained controls of the # lockdown features. Refer to the lockdown_reason documentation in # include/linux/security.h for details. # # The lockdown feature has had signficant design feedback and review # across many subsystems. This code has been in linux-next for some # weeks, with a few fixes applied along the way. # # Stephen Rothwell noted that commit 9d1f8be5cf42 ("bpf: Restrict bpf # when kernel lockdown is in confidentiality mode") is missing a # Signed-off-by from its author. Matthew responded that he is providing # this under category (c) of the DCO" # # * 'next-lockdown' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (31 commits) # kexec: Fix
