RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Renaud Métrich 2021-09-13 13:57:25 UTC 
Description of problem:

A customer running Oracle ASM sees tons of the following messages:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
systemd[SOMEPID]: Failed to stat() device node file /dev/asm/XXX: Permission denied
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

These messages are due to "systemd --user" instances not being able to stat the device node, because /dev/asm directory has not the read/exec permissions for "others":
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
# ls -ld /dev/asm
drwxrwx---   2   0 oraadmin      980 Sep  3 14:46 asm
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

When such device (e.g. /dev/asm/XXX) is a mount point, the "systemd --user" instances complain in the following piece of code:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
 994 static int validate_node(Manager *m, const char *node, struct udev_device **ret) {
 :
1010         if (stat(node, &st) < 0) {
1011                 if (errno != ENOENT)
1012                         return log_error_errno(errno, "Failed to stat() device node file %s: %m", node);
 :
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

The message is printed every time a mount changes in /proc/self/mountinfo, which is not rare at all.


Version-Release number of selected component (if applicable):

systemd-239 and Upstream


How reproducible:

Always


Steps to Reproduce:
1. Change permissions on /dev/mapper

  # chmod 750 /dev/mapper

2. Login as a user

Actual results:

systemd[26327]: Failed to stat() device node file /dev/mapper/rhel-root: Permission denied


Expected results:

No error if issue is "cosmetic" for the "systemd --user" instance.
