This requires a Coverity license, so the usefulness of the instructions
is somewhat limited, but at least I won't have to re-discover everything
from scratch when I need to debug something Coverity-related again in the
future.
systemd-255 is failing a build with the latest kernel headers… Let's downgrade
this warning, because it's fine if there's a file system we don't know about
and it makes thing less brittle if we don't treat this as a hard error.
(I initially conditionalized this on BUILD_MODE, but I don't think we need a
hard error there either. A warning will be noticed and fixed.)
This effectively reverts commit 155d7a2c04.
From RFC 4861 section 6.3.4:
> Note, however, that a Prefix Information option with the on-link flag
> set to zero conveys no information concerning on-link determination and
> MUST NOT be interpreted to mean that addresses covered by the prefix
> are off-link.
So, we should not drop previously configured routes when receieved a RA
with Prefix Information option without on-link flag.
Closes#28435.
bpf_rdonly_cast() was introduced in libbpf commit 688879f together with
the definition of a bpf_core_cast macro. So use that one to avoid
defining a prototype for bpf_rdonly_cast;
The sender must be the first-hop router of the destination. Previously,
we only accepted Redirect messages whose sender is the current default
router with the highest priority.
See RFC 4861 section 8.1 for more details.
Fixes#31981.
It is now called by only ndisc_redirect_handler(), and the check in
ndisc_request_redirect_route() is redundant and already done by
ndisc_redirect_verify_sender().
No functional change, just refactoring.
Hence, ndisc_router_update_redirect() does nothing. Let's remove it.
Also, ndisc_request_route() does not set lifetime for the route, it is
not necessary to set the third argument.
Then, make ndisc_request_route() generic and usable for configuring
routes based on both Router Advertisement and Redirect messages.
Note, ndisc_request_router() never set lifetime, so the dropped comment
in ndisc_request_redirect_route() is wrong.
No functional change, just refactoring.
Setting MTU announced in RA message to routes is problematic, as the
value may be larger than the device MTU (IFLA_MTU), and in such case the
route cannot be used.
These two properties are now set per-interface, and gracefully handled
such invalid cases. Hence not necessary to set them to each route.
Follow-up for #32195.
Unfortunately bfd30e8af6 is not enough and the test fails, that still
occasionally occur, don't provide enough information to see what's
wrong. Let's rework the test a little to improve this, namely:
- redirect curl's output into a temporary file instead of piping it
directly into the "check" expression; that way we can simply dump
the temporary file when the test fails, providing potentially
crucial information. We don't want to always dump everything to
stdout, as some of the tests request an entire system journal (note
that shell redirection instead of `curl -o file` is used
intentionally, so the output file is always nuked first)
- by dropping the pipes in curl commands we can re-enable pipefail
- also, split some very long commands to multiple lines to (slightly)
improve readability
Follow-up for bfd30e8af6.
The logs from TEST-69 still contain a lot of unnecessary shell
metacharacters, so to make the output more readable let's just set
TERM=dumb, instead of having to strip everything semi-manually. Also,
move the related --background= tweak to TEST-69, since it's relevant
only for that particular test.
Follow-up for 8d4bfd38ed.
This also fixes bugs in the previous code where we pass the server
object as userdata to sd_event_add_signal which means that sd-event
tries to use the value of the server pointer as its exit code when
a signal is triggered.
If the build directory is outside of the source tree, ASSERT_XYZ()
triggers the following warning:
