3 years agowait-online: make manager_link_is_online() return 0 when in unmanaged state

wait-online: make manager_link_is_online() return 0 when in unmanaged state

Previously, even if a link is in unmanaged state, the function may
returns positive value. So, even if all managed links are in the configured
sate but do not satisfy the online criteria, e.g., IPv4 address state,
then wait-online finishes with positive value.

This makes the function always return 0 for unmanaged state. So, at
least one managed link must satisfies the online criteria.

This also adds more comments and debugging logs.

3 years agocore: really skip automatic restart when a JOB_STOP job is pending
Franck Bui [Fri, 18 Feb 2022 09:06:24 +0000 (10:06 +0100)]
core: really skip automatic restart when a JOB_STOP job is pending

It's not clear why we rescheduled a service auto restart while a stop job for
the unit was pending. The comment claims that the unit shouldn't be restarted
but the code did reschedule an auto restart meanwhile.

In practice that was rarely an issue because the service waited for the next
auto restart to be rescheduled, letting the queued stop job to be proceed and
service_stop() to be called preventing the next restart to complete.

However when RestartSec=0, the timer expired right away making PID1 to
reschedule the unit again, making the timer expired right away... and so
on. This busy loop prevented PID1 to handle any queued jobs (and hence giving
no chance to the start rate limiting to trigger), which made the busy loop last
forever.

This patch breaks this loop by skipping the reschedule of the unit auto restart
and hence not depending on the value of u->restart_usec anymore.

3 years agopid1: set SYSTEMD_NSS_DYNAMIC_BYPASS=1 env var for dbus-daemon
Lennart Poettering [Thu, 17 Feb 2022 13:49:54 +0000 (14:49 +0100)]
pid1: set SYSTEMD_NSS_DYNAMIC_BYPASS=1 env var for dbus-daemon

There's currently a deadlock between PID 1 and dbus-daemon: in some
cases dbus-daemon will do NSS lookups (which are blocking) at the same
time PID 1 synchronously blocks on some call to dbus-daemon. Let's break
that by setting SYSTEMD_NSS_DYNAMIC_BYPASS=1 env var for dbus-daemon,
which will disable synchronously blocking varlink calls from nss-systemd
to PID 1.

In the long run we should fix this differently: remove all synchronous
calls to dbus-daemon from PID 1. This is not trivial however: so far we
had the rule that synchronous calls from PID 1 to the dbus broker are OK
as long as they only go to interfaces implemented by the broke itself
rather than services reachable through it. Given that the relationship
between PID 1 and dbus is kinda special anyway, this was considered
acceptable for the sake of simplicity, since we quite often need
metadata about bus peers from the broker, and the asynchronous logic
would substantially complicate even the simplest method handlers.

This mostly reworks the existing code that sets SYSTEMD_NSS_BYPASS_BUS=
(which is a similar hack to deal with deadlocks between nss-systemd and
dbus-daemon itself) to set SYSTEMD_NSS_DYNAMIC_BYPASS=1 instead. No code
was checking SYSTEMD_NSS_BYPASS_BUS= anymore anyway, and it used to
solve a similar problem, hence it's an obvious piece of code to rework
like this.

basic: mac_[selinux,smack]_apply_fd does not work when applying labels

Commit a7fdc6c introduced a regression where file descriptors are opened
using O_PATH option. mac_smack_apply_fd() calls fsetxattr() and would fail
with a -EBADF (Bad file descriptor) error.

Use FORMAT_PROC_FD_PATH(fd) to convert the fd back into a full path and
call setxattr() or setfilecon() instead.

core/namespace: s/normalize_mounts()/drop_unused_mounts()

Rename the normalize_mounts() helper to drop_unused_mounts. All the
helpers called in there get rid of mounts that are unused for a variety
of reasons. And whereas the helpers are aptly prefixed with "drop" the
overall helper isn't and instead uses "normalize".

Make it more obvious what the helper actually does by renaming it from
normalize_mounts() to drop_unused_mounts(). Readers of code calling this
helper will immediately see that it will get rid of unused mounts.
