systemd-logind: allow using BootLoaderEntries DBUS property systemd-logind exposes several properties related to the bootloader. One of them is BootLoaderEntries [1], which scans the disks using util-linux's blkid in order to find the ESP (EFI System Partition) [2][3]. This triggers the following logs in audit.log (where /dev/sda1 is the ESP, mounted on /boot): type=AVC msg=audit(1577692922.834:310): avc: denied { getattr } for pid=690 comm="systemd-logind" name="/" dev="sda1" ino=1 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:dosfs_t tclass=filesystem permissive=1 type=AVC msg=audit(1577692922.841:311): avc: denied { search } for pid=690 comm="systemd-logind" name="/" dev="sda1" ino=1 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:dosfs_t tclass=dir permissive=1 type=AVC msg=audit(1577692922.841:312): avc: denied { getattr } for pid=690 comm="systemd-logind" path="/boot" dev="sda1" ino=1 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:dosfs_t tclass=dir permissive=1 type=AVC msg=audit(1577692922.841:313): avc: denied { read } for pid=690 comm="systemd-logind" name="sda1" dev="devtmpfs" ino=2496 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:fixed_disk_device_t tclass=blk_file permissive=1 type=AVC msg=audit(1577692922.841:313): avc: denied { open } for pid=690 comm="systemd-logind" path="/dev/sda1" dev="devtmpfs" ino=2496 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:fixed_disk_device_t tclass=blk_file permissive=1 type=AVC msg=audit(1577692922.844:314): avc: denied { getattr } for pid=690 comm="systemd-logind" path="/dev/sda1" dev="devtmpfs" ino=2496 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:fixed_disk_device_t tclass=blk_file permissive=1 type=AVC msg=audit(1577692922.844:315): avc: denied { ioctl } for pid=690 comm="systemd-logind" path="/dev/sda1" dev="devtmpfs" ino=2496 ioctlcmd=0x1272 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:fixed_disk_device_t tclass=blk_file permissive=1 type=AVC msg=audit(1577692922.851:316): avc: denied { read } for pid=690 comm="systemd-logind" name="loader.conf" dev="sda1" ino=4 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:dosfs_t tclass=file permissive=1 type=AVC msg=audit(1577692922.851:316): avc: denied { open } for pid=690 comm="systemd-logind" path="/boot/loader/loader.conf" dev="sda1" ino=4 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:dosfs_t tclass=file permissive=1 type=AVC msg=audit(1577692922.851:317): avc: denied { getattr } for pid=690 comm="systemd-logind" path="/boot/loader/loader.conf" dev="sda1" ino=4 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:dosfs_t tclass=file permissive=1 type=AVC msg=audit(1577692922.851:318): avc: denied { ioctl } for pid=690 comm="systemd-logind" path="/boot/loader/loader.conf" dev="sda1" ino=4 ioctlcmd=0x5401 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:dosfs_t tclass=file permissive=1 type=AVC msg=audit(1577692922.851:319): avc: denied { read } for pid=690 comm="systemd-logind" name="entries" dev="sda1" ino=5 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:dosfs_t tclass=dir permissive=1 type=AVC msg=audit(1577692922.851:319): avc: denied { open } for pid=690 comm="systemd-logind" path="/boot/loader/entries" dev="sda1" ino=5 scontext=system_u:system_r:systemd_logind_t tcontext=system_u:object_r:dosfs_t tclass=dir permissive=1 As allowing read access to fixed disks (such as /dev/sda1 here) can be considered as dangerous, add a conditional to allow the accesses.

Setup generic generator attribute and change generator types. I'm seeing problems on RHEL7 with lvm2-activation-generator that are coming from recent changes to put systemd-fstab-generator into it's own domain. I resolved the issues by creaing this generator attribute to grant common generator permissions and move all generators into a single systemd_generator_t domain. Then setup specific types for the following generators: lvm2-activation-generator - needs to read lvm2 config systemd-sysv-generator - needs to read stuff in init_t that other generators don't. systemd-efi-boot-generator - needs to read stuff on the EFI boot partition labeled boot_t For fstab generator allow it to write /sys [ 19.482951] type=1400 audit(1584548691.268:7): avc: denied { write } for pid=1638 comm="systemd-fstab-g" name="/" dev="sysfs" ino=1 Allow scontext=system_u:system_r:systemd_fstab_generator_t:s0 tcontext=system_u:object_r:sysfs_t:s0 tclass=dir permissive=1 audit(1585500099.139:6): avc: denied { read } for pid=1635 comm="systemd-cryptse" path="/run/systemd/generator/dev-mapper-luks\x2d6a613af0\x2d0a61\x2d462f\x2d8679\x2d1b0d964fbc88.device.d/.#90-device-timeout.confsOskdU" dev="tmpfs" ino=12243 scontext=system_u:system_r:systemd_generator_t:s0 tcontext=system_u:object_r:init_runtime_t:s0 tclass=file permissive=1 audit(1585500099.139:7): avc: denied { setattr } for pid=1635 comm="systemd-cryptse" name=".#90-device-timeout.confsOskdU" dev="tmpfs" ino=12243 scontext=system_u:system_r:systemd_generator_t:s0 tcontext=system_u:object_r:init_runtime_t:s0 tclass=file permissive=1 audit(1585500099.139:8): avc: denied { rename } for pid=1635 comm="systemd-cryptse" name=".#90-device-timeout.confsOskdU" dev="tmpfs" ino=12243 scontext=system_u:system_r:systemd_generator_t:s0 tcontext=system_u:object_r:init_runtime_t:s0 tclass=file permissive=1 Signed-off-by: Dave Sugar <dsugar@tresys.com>

systemd: allow reading options from EFI variable SystemdOptions Since systemd 244, systemd can parse EFI variable SystemdOptions-8cf2644b-4b0b-428f-9387-6d876050dc67 like /proc/cmdline in order to find options. systemd's NEWS file [1] states: systemd will also read configuration options from the EFI variable SystemdOptions. This may be used to configure systemd behaviour when modifying the kernel command line is inconvenient, but configuration on disk is read too late, for example for the options related to cgroup hierarchy setup. 'bootctl systemd-efi-options' may be used to set the EFI variable. In practice, all callers of log_parse_environment() read this EFI variable, because: * log_parse_environment() is a macro which is expanded to log_parse_environment_realm(LOG_REALM) [2]. * log_parse_environment_realm() calls proc_cmdline_parse() when being use in system daemons [3]. * proc_cmdline_parse() always calls systemd_efi_options_variable() [4]. * systemd_efi_options_variable() reads SystemdOptions variable [5]. For SELinux, this means that every domain with attribute systemd_log_parse_env_type wants to read an EFI variable. Allow this access.

systemd-logind: allow using BootLoaderEntries DBUS property systemd-logind exposes several properties related to the bootloader. One of them is BootLoaderEntries [1], which scans the disks using util-linux's blkid in order to find the ESP (EFI System Partition) [2][3].
