Provide the full kernel boot option string (with ending '=' sign). They won't work without that and that is how other boot options are listed. If used without an '=' sign (as listed here), they cause an "Unknown parameters" message and are added to init's argument strings, polluting them. Unknown kernel command line parameters "enforcing checkreqprot BOOT_IMAGE=/boot/bzImage-517rc6", will be passed to user space. Run /sbin/init as init process with arguments: /sbin/init enforcing checkreqprot with environment: HOME=/ TERM=linux BOOT_IMAGE=/boot/bzImage-517rc6 Fixes: ^1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Cc: Paul Moore <paul@xxxxxxxxxxxxxx> Cc: Stephen Smalley <stephen.smalley.work@xxxxxxxxx> Cc: Eric Paris <eparis@xxxxxxxxxxxxxx> Cc: selinux@xxxxxxxxxxxxxxx Cc: Jonathan Corbet <corbet@xxxxxxx> --- Documentation/admin-guide/kernel-parameters.txt | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) --- linux-next-20220228.orig/Documentation/admin-guide/kernel-parameters.txt +++ linux-next-20220228/Documentation/admin-guide/kernel-parameters.txt @@ -550,7 +550,7 @@ nosocket -- Disable socket memory accounting. nokmem -- Disable kernel memory accounting. - checkreqprot [SELINUX] Set initial checkreqprot flag value. + checkreqprot= [SELINUX] Set initial checkreqprot flag value.
