Setting no_new_privs does not stop UID changes, but rather blocks
gaining privileges through execve(). Also fixes a small typo.

Tree wide cleanups

This reverts commit 75ead2b753cb9586f3f208326446081baab70da1.
Follow up for #4546:
> @@ -848,8 +848,7 @@ static int bus_kernel_make_message(sd_bus *bus, struct kdbus_msg *k) {

let's get this out today!
|
|
Just to make the whole thing easier for users.
|
|
Now that the list is user-visible, @default should be first.
|
|
This should make it easier for users to understand what each filter
means as the list of syscalls is updated in subsequent systemd versions.

Make sure that when DynamicUser= is set that we intialize the user
supplementary groups and that we also support SupplementaryGroups=

Two testsuite tweaks
|
|
xsprintf revert
|
|
|
|
|
|
If we encounter the (unlikely) situation where the combined path to the
new root and a path to a mount to be moved together exceed maximum path length,
we shouldn't crash, but fail this path instead.
|
|
|
|
This reverts some changes introduced in d054f0a4d4.
xsprintf should be used in cases where we calculated the right buffer
size by hand (using DECIMAL_STRING_MAX and such), and never in cases where
we are printing externally specified strings of arbitrary length.
Fixes #4534.
|
|
Add "perpetual" unit concept, sysctl fixes, networkd fixes, systemctl color fixes, nspawn discard.
|
|
preparation for 232
|
|
|
|
overly long description strings
This essentially reverts one part of d054f0a4d451120c26494263fc4dc175bfd405b1.
(We might also choose to use proper ellipsation here, but I wasn't sure the
memory allocation this requires wouöld be a good idea here...)
Fixes: #4534

Preserve stored fds over service restart
|
|
Reported by @evverx in #4493.
|

more seccomp fixes, and change of order of selinux/aa/smack and seccomp application on exec

Unfortunately, github drops the original commiter when a PR is "squashed" (even
if it is only a single commit) and replaces it with some rubbish
github-specific user id. Thus, to make the contributors list somewhat useful,
update the .mailmap file and undo all the weirdness github applied there.
|
|
Since service_add_fd_store() already does the check, remove the redundant check
from service_add_fd_store_set().
Also, print a warning when repopulating FDStore after daemon-reexec and we hit
the limit. This is a user visible issue, so we should not discard fds silently.
(Note that service_deserialize_item is impacted by the return value from
service_add_fd_store(), but we rely on the general error message, so the caller
does not need to be modified, and does not show up in the diff.)
|
|
Let's propagate the error here, instead of eating it up early.
In a later change we should probably also change mount_enumerate() to propagate
errors up, but that would mean we'd have to change the unit vtable, and thus
change all unit types, hence is quite an invasive change.
|
|
Fixes: #3870
|
|
|
|
Let's make sure that our loopback files remain sparse, hence let's set
"discard" as mount option on file systems that support it if the backing device
is a loopback.
|
|
Make the underlining between the header and the body and between the units of
different types span the whole width of the table.
Let's never make the table wider than necessary (which is relevant due the
above).
When space is limited and we can't show the full ID or description string
prefer showing the full ID over the full description. The ID is after all
something people might want to copy/paste, while the description is mostly just
helpful decoration.
|
|
If we turn on red color for the active column and it is not combined with
underlining, then we need to turn it off explicitly afterwards. Do that.
|
|
Let's place only one ternary operator.
|
|
Let's only check for eof once after the fgets(). There's no point in checking
EOF before the first read, and twice in each loop.
|
|
|
|
This way, we can get rid of a label/goto.
