Summary	0016645: SELinux is preventing /usr/sbin/smartd from 'ioctl' accesses on the chr_file /dev/nvme0.
Description	Description of problem: If you install smartmontools then (periodically) smartd wants to access your blockdevices This generates a SELinux Alert SELinux is preventing /usr/sbin/smartd from 'ioctl' accesses on the chr_file /dev/nvme0. *** Plugin catchall (100. confidence) suggests ************************ If you believe that smartd should be allowed ioctl access on the nvme0 chr_file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'smartd' --raw \| audit2allow -M my-smartd # semodule -i my-smartd.pp Additional Information: Source Context system_u:system_r:fsdaemon_t:s0 Target Context system_u:object_r:nvme_device_t:s0 Target Objects /dev/nvme0 [ chr_file ] Source smartd Source Path /usr/sbin/smartd Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-252.el7.1.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 3.10.0-1062.1.2.el7.x86_64 #1 SMP Mon Sep 30 14:19:46 UTC 2019 x86_64 x86_64 Alert Count 319 First Seen 2019-10-07 08:39:04 CEST Last Seen 2019-10-24 08:16:00 CEST Local ID bbbe8cc7-e933-4860-9024-0880541fbd7b Raw Audit Messages type=AVC msg=audit(1571897760.413:455): avc: denied { ioctl } for pid=1564 comm="smartd" path="/dev/nvme0" dev="devtmpfs" ino=8080 ioctlcmd=4e41 scontext=system_u:system_r:fsdaemon_t:s0 tcontext=system_u:object_r:nvme_device_t:s0 tclass=chr_file permissive=1 Hash: smartd,fsdaemon_t,nvme_device_t,chr_file,ioctl Version-Release number of selected component: selinux-policy-3.13.1-252.el7.1.noarch

TrevorH 2020-02-11 10:39 manager ~0036258	what does `rpm -q smartmontools selinux-policy` say?

vytenis 2020-02-11 11:00 reporter ~0036259	Here's the info: # rpm -q smartmontools selinux-policy smartmontools-7.0-1.el7.x86_64 selinux-policy-3.13.1-252.el7_7.6.noarch The system was upgraded and rebooted recently. No packages marked for update

TrevorH 2020-02-11 11:05 manager ~0036260	I have a newer smartmontools installed : smartmontools-7.0-1.el7_7.1.x86_64 I would suggest updating to see if it helps.

vytenis 2020-02-11 11:43 reporter ~0036262	Sorry, my bad. Our repo was stalled.
