From 8d6d51edcb79b0906288170df165c1b86e278218 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Mon, 28 Feb 2022 20:14:54 -0800 Subject: [PATCH] docs: selinux: add '=' signs to kernel boot options 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 Signed-off-by: Randy Dunlap Cc: Paul Moore Cc: Stephen Smalley Cc: Eric Paris Cc: selinux@vger.kernel.org Cc: Jonathan Corbet [PM: removed bogus 'Fixes' line] Signed-off-by: Paul Moore --- Documentation/admin-guide/kernel-parameters.txt | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/Documentation/admin-guide/kernel-parameters.txt b/Documentation/admin-guide/kernel-parameters.txt index 8090130..815af6d 100644 --- a/Documentation/admin-guide/kernel-parameters.txt +++ b/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.
