2023-01-13tomoyo: Remove "select SRCU"Paul E. McKenney1-1/+0
Now that the SRCU Kconfig option is unconditionally selected, there is no longer any point in selecting it. Therefore, remove the "select SRCU" Kconfig statements. Signed-off-by: Paul E. McKenney <paulmck@kernel.org> Signed-off-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp>
2023-01-09tomoyo: Omit use of bin2cMasahiro Yamada1-1/+0
bin2c was, as its name implies, introduced to convert a binary file to C code. However, I did not see any good reason ever for using this tool because using the .incbin directive is much faster, and often results in simpler code. Most of the uses of bin2c have been killed, for example: - 13610aa908dc ("kernel/configs: use .incbin directive to embed config_data.gz") - 4c0f032d4963 ("s390/purgatory: Omit use of bin2c") security/tomoyo/Makefile has even less reason for using bin2c because the policy files are text data. So, sed is enough for converting them to C string literals, and what is nicer, generates human-readable builtin-policy.h. This is the last user of bin2c. After this commit lands, bin2c will be removed.

2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada1-3/+3
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2019-05-10tomoyo: Add a kernel config option for fuzzing testing.Tetsuo Handa1-0/+10
syzbot is reporting kernel panic triggered by memory allocation fault injection before loading TOMOYO's policy [1]. To make the fuzzing tests useful, we need to assign a profile other than "disabled" (no-op) mode. Therefore, let's allow syzbot to load TOMOYO's built-in policy for "learning" mode using a kernel config option. This option must not be enabled for kernels built for production system, for this option also disables domain/program checks when modifying policy configuration via /sys/kernel/security/tomoyo/ interface.

2015-04-07tomoyo: Use bin2c to generate builtin-policy.hMichal Marek1-0/+1
Simplify the Makefile by using a readily available tool instead of a custom sed script. The downside is that builtin-policy.h becomes unreadable for humans, but it is only a generated file. Acked-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Signed-off-by: Michal Marek <mmarek@suse.cz>
2015-01-06rcu: Make SRCU optional by using CONFIG_SRCUPranith Kumar1-0/+1
SRCU is not necessary to be compiled by default in all cases. For tinification efforts not compiling SRCU unless necessary is desirable. The current patch tries to make compiling SRCU optional by introducing a new Kconfig option CONFIG_SRCU which is selected when any of the components making use of SRCU are selected. If we do not select CONFIG_SRCU, srcu.o will not be compiled at all. text data bss dec hex filename 2007 0 0 2007 7d7 kernel/rcu/srcu.o Size of arch/powerpc/boot/zImage changes from text data bss dec hex filename 831552 64180 23944 919676 e087c arch/powerpc/boot/zImage : before 829504 64180 23952 917636 e0084 arch/powerpc/boot/zImage : after so the savings are about ~2000 bytes.

2011-06-29TOMOYO: Make several options configurable.Tetsuo Handa1-0/+61
To be able to start using enforcing mode from the early stage of boot sequence, this patch adds support for activating access control without calling external policy loader program. This 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. This patch makes several variables configurable on build time. This patch also adds TOMOYO_loader= and TOMOYO_trigger= kernel command line option to boot the same kernel in two different init systems (BSD-style init and systemd).
