tough neverallow
by Henry Zhang
Hi folks,
I meet a tough neverallow problem:
(neverallow base_typeattr_8 self (capability (sys_module)))
| <root>
| allow at
/mnt/disk2/henryzhang/sec-4715/connectivity-bsp/build-ctx0700-updater/tmp/work/ctx0700-fsl-linux/refpolicy-mcs/2.20190201-r0/image/var/lib/selinux/mcs/tmp/modules/100/ota_client/cil:678
| (allow ota_client_t self (capability (net_raw sys_module sys_resource
mknod)))
The SELinux interface does not contain ota_client_t but file
usr/share/selinux/devel/include/system/unconfined.if: allow $1
self:capability ~{ sys_module };
I do not know how to make following worked
allow ota_client_t self (capability (net_raw sys_module sys_resource mknod))
Please advise.
Thanks.

user configuration
by Henry Zhang
Hi,
I want to understand content of seuser configuration as:
root:root:s0-s0:c0.c1023
__default__:user_u:s0-s0
I do not know why it looks like that.

neverallowed
by Henry Zhang
Hi,
How should I handle neverallowed?
1. make it worked bypass it?
2. make some change on the rule to avoid hit neverallowed?
Thanks

label
by Henry Zhang
Hi,
I want to do custom SELinux with policies.
The first challenge I am facing is to check if the label is correct or not
instead of using audit2allow first.
How do I know if labeling is correct in a denied message from
/var/log/audit.log?
Thanks.

get rid of setenforce
by Henry Zhang
Hi folks,
setenforce allows users to swap selinux mode between enforcing and
permissive.
If I want my selinux to stay in enforcing mode forever so that nobody is
able to interfere with my selinux.
What should I do?
Thanks.

Re: get rid of setenforce
by donniet＠tds.net
The "setenforce" utility require root privileges to run. If you don't want people to mess with your SELinux configuration, don't give them the privileges to do it. First, don't give anyone the password for the root user. Secondly, instead of granting full sudo privileges to your users, just grant them whatever sudo privileges they need to perform their jobs, and nothing else.

Henry,
With SELinux you can confine the root user and enable
the secure_mode_policyload boolean.

Mike,
If SELinux mode can be set to permissive temporarily so that people can
control the device.
any way to prevent that?
