[yocto] [meta-security][PATCH] linux-yocto: drop all 4.1 content
Mikko Ylinen
mikko.ylinen at linux.intel.com
Tue Aug 29 05:45:18 PDT 2017
linux-yocto_4.1.bb recipe has been removed from oe-core master
and that triggers a bitbake error due to orphan bbappends
maintained in meta-security.
To fix the error, drop linux-yocto_4.1.bbappend plus the patches
and the config fragments for it.

-+
-+config CCSECURITY_LKM
-+ bool "Compile as loadable kernel module"
-+ default n
-+ depends on CCSECURITY && MODULES
-+ help
-+ This version of TOMOYO depends on patching the kernel source in order
-+ to insert some hooks which LSM does not provide. Therefore,
-+ recompiling the kernel is inevitable. But if you want to keep
-+ vmlinux's size as small as possible, you can compile most part of
-+ TOMOYO as a loadable kernel module by saying Y here.
-+
-+config CCSECURITY_DISABLE_BY_DEFAULT
-+ bool "Disable by default"
-+ default n
-+ depends on CCSECURITY
-+ help
-+ Say Y here if you want TOMOYO disabled by default.
-+ To enable TOMOYO, pass ccsecurity=on to kernel command line.
-+ To disable TOMOYO, pass ccsecurity=off to kernel command line.
-+
-+config CCSECURITY_USE_EXTERNAL_TASK_SECURITY
-+ bool "Do not modify 'struct task_struct' in order to keep KABI"
-+ default n
-+ depends on CCSECURITY
-+ help
-+ Say Y here if you want to keep KABI for prebuilt kernel modules
-+ unchanged. TOMOYO needs "struct ccs_domain_info *" and "u32" for each
-+ "struct task_struct". But embedding these variables into
-+ "struct task_struct" breaks KABI for prebuilt kernel modules (which
-+ means that you will need to rebuild prebuilt kernel modules).
-+ If you say Y here, these variables are managed outside
-+ "struct task_struct" rather than embedding into "struct task_struct",
-+ but accessing these variables becomes slower because lookup operation
-+ is performed every time the current thread needs to access them.
-+
-+config CCSECURITY_MAX_ACCEPT_ENTRY
-+ int "Default maximal count for learning mode"
-+ default 2048
-+ range 0 2147483647
-+ depends on CCSECURITY
-+ help
-+ This is the default value for maximal ACL entries
-+ that are automatically appended into policy at "learning mode".
-+ Some programs access thousands of objects, so running
-+ such programs in "learning mode" dulls the system response
-+ and consumes much memory.
-+ This is the safeguard for such programs.
-+
-+config CCSECURITY_MAX_AUDIT_LOG
-+ int "Default maximal count for audit log"
-+ default 1024
-+ range 0 2147483647
-+ depends on CCSECURITY
-+ help
-+ This is the default value for maximal entries for
-+ audit logs that the kernel can hold on memory.
-+ You can read the log via /proc/ccs/audit.
-+ If you don't need audit logs, you may set this value to 0.
-+
-+config CCSECURITY_OMIT_USERSPACE_LOADER
-+ bool "Activate without calling userspace policy loader."
-+ default n
-+ depends on CCSECURITY
-+ ---help---
-+ Say Y here if you want to activate access control as soon as built-in
-+ policy was loaded. This option will be useful for systems where
-+ operations which can lead to the hijacking of the boot sequence are
-+ needed before loading the policy. For example, you can activate
-+ immediately after loading the fixed part of policy which will allow
-+ only operations needed for mounting a partition which contains the
-+ variant part of policy and verifying (e.g. running GPG check) and
-+ loading the variant part of policy. Since you can start using
-+ enforcing mode from the beginning, you can reduce the possibility of
-+ hijacking the boot sequence.
-+
-+ If you say Y to both "Compile as loadable kernel module" option and
-+ "Activate without calling userspace policy loader." option, be sure
-+ to excplicitly load the kernel module from the userspace, for
-+ the kernel will not call /sbin/ccs-init when /sbin/init starts.
