We parse the string supplied in NTP_SERVERS during configuration under an
assert_se(). Right now we will accept pretty much anything there, but in case
we are more picky in the future, add a simple test which checks that we can
actually parse whatever is in NTP_SERVERS so that we don't fail the assertion
at runtime.
Currently the local variable `address` is unintialized if the DHCP lease
doesn't provide a router address (when r == -ENODATA). Thus the
subsequent call to route_scope_from_address will result in accessing an
unintialized variable.
As a matter of fact, sd-dhcp-client ignores DHCP leases without an
address so link_dhcp_set_routes probably will never be called without a
valid address.
Since commit 36c16a7cdd ("core: rework unit timeout handling, and add
new setting RuntimeMaxSec=") TimeoutSec=0 in mount units has
cause the mount to timeout immediately instead of never as documented.
There is a similar problem with Socket.TimeoutSec and Swap.TimeoutSec.
These are easily fixed using config_parse_sec_fix_0().
Automount.TimeoutIdleSec looks like it could have the same problem,
but doesn't because the kernel treats '0' as 'no timeout'.
It handle USEC_INFINITY correctly only because that constant has
the value '-1', and when round up, it becomes zero.
To avoid possible confusion, use config_parse_sec_fix_0() as well, and
explicitly handle USEC_INFINITY.
LLDP should be received on bridge slaves as they're the entities
directly connected to a peer. Receiving LLDP on the bridge device makes
little sense, Linux by default even filters out LLDP going onto the
bridge device.
Flip the current logic, receive LLDP on bridge slaves don't listen for
them on the bridge itself.
Let's log about this in the caller.
Doesn't really matter, but let's do something about my OCD, and
propagate errors properly, so that the caller can log about them.
Let's downgrade the warning introduced by
955d99edc7 to debug, as we really
shouldn't log at more than debug level from library code.
(And while we are at it, print the MTU as the right (unsigned) type in
the format string.)
unit_name_template returns -EINVAL if the unit name is not a template, but
the code assumed that OOM is the only failure mode. Fix that to emit the warning
if a non-template unit is encountered (because in this case we expect the name
to match exactly), and just skip the warning on other errors (presumably oom).
Fixes#5543.
DHCP responses could include static routes, but unfortunately not an
option to tell what scope to use. So it's important that the client sets
it properly.
This mimics what the `ip route add` command does when adding a static
route without an explicit scope:
* If the destination IP is on the local host, use scope `host`
* Otherwise if the gateway IP is null (direct route), use scope `link`
* If anything else, use the current default `global`.
Fixes#5979.
*scanf functions set errno on i/o error. For sscanf, this doesn't really apply,
so (based on the man page), it seems that errno is unlikely to be ever set to a
useful value. So just ignore errno. The error message includes the string that
was parsed, so it should be always pretty clear why parsing failed.
On the other hand, detect trailing characters and minus prefix that weren't
converted properly. This matches what our safe_ato* functions do. Add tests to
elucidate various edge cases.
All those uses were correct, but I think it's better to be explicit.
Using implicit errno is too error prone, and with this change we can require
(in the sense of a style guideline) that the code is always specified.
Helpful query: git grep -n -P 'log_[^s][a-z]+\(.*%m'
MESSAGE=data\n and MESSAGE\n40000000data\n are both valid serializations, so
they should be stored in the journal. Before, MESSAGE, SYSLOG_FACILITY,
SYSLOG_IDENTIFIER, PRIORITY, and OBJECT_PID would be only honoured if they were
given in the first form.
Fixed#5973.
For all except the last entry in a single packet, we would dispatch the
message to the journal, but not forward it, nor perform proper cleanup.
Rewrite the code to process each entry in a helper function, and make
server_process_native_message() just call this function in a loop.
Fixes#5643.
v2:
- properly decrement *remaining when processing entry separator
The intent of the hwdb entry for the Cube iWork8 air tablet buttons is
to fix them being swapped. The kernel is using left-meta for the
home key (it is being treated as the windows key on keyboards, as it has
a windows logo on most x86 tablets).
Fix the hwdb entry to only swap the buttons and not change the keycode
emitted by the home key.
timex::time::tv_sec can have different sizes depending on the
host architecture. On x32 in particular, it is 8 bytes
long while the long int type is only 4 bytes long. Hence,
using li as a format specifier will trigger a format
error. Thus, better use PRI_TIME instead of li which is
actually the right format specifier to use for time_t.
Enable masking the /proc folder using the 'InaccessiblePaths' unit
option.
This also slightly simplify mounts setup as the bind_remount_recursive
function will only open /proc/self/mountinfo once.
This is based on the suggestion at:

timex::time::tv_usec and timex::freq can have different sizes
depending on the host architecture. On x32 in particular,
it is 8 bytes long while the long int type is only 4 bytes
long. Hence, using li as a format specifier will trigger
a format error. Thus, introduce a new format specifier
PRI_TIMEX which is defined as PRIi64 on x32 and li
everywhere else.
timespec::tv_nsec can have different sizes depending on the
host architecture. On x32 in particular, it is 8 bytes long
while the long int type is only 4 bytes long. Hence, using
ld as a format specifier will trigger a format error. Thus,
explicitly cast timespec::tv_nsec to nsec_t and use PRI_NSEC
as the format specifier to make sure the sizes for both match.

When we first handle a device with an EVDEV_ABS override, check if it has
EV_ABS bits. If not, print a warning and continue. This is required on devices
where the match string applies to multiple device nodes, not all of which may
have absolute axes.

c20e6de897 introduced a format string as
variable, but didn't turn off -Wformat-nonliteral warnings on it, thus
breaking the build. Let's fix that, by simply turning off the warning in
this case, as we know it's safe.
