I added the test if an optional parameter is not empty, but that doesn't work
with -u. Provide an empty "fallback" value to fix the issue.
Also group the update steps so that it's easier to see what is going on.
Remount, and subsequent umount, attempts can hang for inaccessible network
based mount points. This can leave a system in a hard hang state that
requires a hard reset in order to recover. This change moves the remount,
and umount attempts into separate child processes. The remount and umount
operations will block for up to 90 seconds (DEFAULT_TIMEOUT_USEC). Should
those waits fail, the parent will issue a SIGKILL to the child and continue
with the shutdown efforts.
In addition, instead of only reporting some additional errors on the final
attempt, failures are reported as they occur.
With Type=notify services, EXTEND_TIMEOUT_USEC= messages will delay any startup/
runtime/shutdown timeouts.
A service that hasn't timed out, i.e, start time < TimeStartSec,
runtime < RuntimeMaxSec and stop time < TimeoutStopSec, may by sending
EXTEND_TIMEOUT_USEC=, allow the service to continue beyond the limit for
the execution phase (i.e TimeStartSec, RunTimeMaxSec and TimeoutStopSec).
EXTEND_TIMEOUT_USEC= must continue to be sent (in the same way as
WATCHDOG=1) within the time interval specified to continue to reprevent
the timeout from occuring.
Watchdog timeouts are also extended if a EXTEND_TIMEOUT_USEC is greater
than the remaining time on the watchdog counter.
Fixes#5868.
These helper calls are potentially called often, and allocate FILE*
objects internally for a very short period of time, let's turn off
locking for them too.
Let's replace usage of fputc_unlocked() and friends by __fsetlocking(f,
FSETLOCKING_BYCALLER). This turns off locking for the entire FILE*,
instead of doing individual per-call decision whether to use normal
calls or _unlocked() calls.
This has various benefits:
1. It's easier to read and easier not to forget
2. It's more comprehensive, as fprintf() and friends are covered too
(as these functions have no _unlocked() counterpart)
3. Philosophically, it's a bit more correct, because it's more a
property of the file handle really whether we ever pass it on to another
thread, not of the operations we then apply to it.
This patch reworks all pieces of codes that so far used fxyz_unlocked()
calls to use __fsetlocking() instead. It also reworks all places that
use open_memstream(), i.e. use stdio FILE* for string manipulations.
Note that this in some way a revert of 4b61c87511.
This changes dns_name_between() to deal properly with checking whether B
is between A and C if A and C are equal. Previously we simply returned
-EINVAL in this case, refusing checking. With this change we correct
behaviour: if A and C are equal, then B is "between" both if it is
different from them. That's logical, since we do < and > comparisons, not
<= and >=, and that means that anything "right of A" and "left of C"
lies in between with wrap-around at the ends. And if A and C are equal
that means everything lies between, except for A itself.
This fixes handling of domains using NSEC3 "white lies", for example the
.it TLD.
Fixes: #7421
fputs() writes only first 2048 bytes and fails
to write to /proc when values are larger than that.
This patch adds a new flag to WriteStringFileFlags
that make it possible to disable the buffer under
specific cases.
This commit updates networkd behavior to check if the hostname option
received via DHCP is too long for Linux limit, and in case shorten it.
An overlong hostname will be truncated to the first dot or to
`HOST_MAX_LEN`, whatever comes earlier.
Since the new option `--network-namespace-path=` of systemd-nspawn
cannot be used together with other network-related options, we need
to add more smoke tests for checking these conditions of options.
Add a new option `--network-namespace-path` to systemd-nspawn to allow
users to specify an arbitrary network namespace, e.g. `/run/netns/foo`.
Then systemd-nspawn will open the netns file, pass the fd to
outer_child, and enter the namespace represented by the fd before
running inner_child.
```
$ sudo ip netns add foo
$ mount | grep /run/netns/foo
nsfs on /run/netns/foo type nsfs (rw)
...
$ sudo systemd-nspawn -D /srv/fc27 --network-namespace-path=/run/netns/foo \
/bin/readlink -f /proc/self/ns/net
/proc/1/ns/net:[4026532009]
```
Note that the option `--network-namespace-path=` cannot be used together
with other network-related options such as `--private-network` so that
the options do not conflict with each other.

Using strlen() to declare a buffer results in a variable-length array,
even if the compiler likely optimizes it to be a compile time constant.
When building with -Wvla, certain versions of gcc complain about such
buffers. Compiling with -Wvla has the advantage of preventing variably
length array, which defeat static asserts that are implemented by
declaring an array of negative length.
While the compiler likely optimizes strlen(x) for string literals,
it is not a constant expression.
Hence,
char buffer[strlen("OPTION_000") + 1];
declares a variable-length array. STRLEN() can be used instead
when a constant espression is needed.
It's not entirely identical to strlen(), as STRLEN("a\0") counts 2.
Also, it only works with string literals and the macro enforces
that the argument is a literal.
Let's rename escaped_name to disk_path since this is an actual content
that pointer refers to. It is either path to encrypted block device
or path to encrypted image file.
Also drop redundant function disk_major_minor(). src is always set, and
it always points to either encrypted block device path (or symlink to
such device) or to encrypted image. In case it is set to device path
there is no need to reset it to /dev/block/major:minor symlink since
those paths are equivalent.
We might end up allocating mempools, and when we are unloaded we might
orphan them, thus leaking them. Hence, let's just stick around for good,
so the mempools remain referenced continously and for good, and thus no
memory is leaked (though the memory isn't cleaned up either).
Fixes: #7596
Some ask-password agents (e.g. clevis-luks-askpass) use Id option from
/run/systemd/ask-password/ask* file in order to obtain the password for
the device.
Id option should be in the following format,
e.g. Id=subsystem:data. Where data part is supposed to identify object
that ask-password query is done for. Since
e51b9486d1 this field has format
Id=cryptsetup:/dev/block/major:minor when systemd-cryptsetup is
unlocking encrypted block device. However, crypttab also supports
encrypted image files in which case we usually set data part of Id to
"vol on mountpoint". This is unexpected and actually breaks network
based device encryption as implemented by clevis.
Example:
$ cat /etc/crypttab
clevis-unlocked /clevis-test-disk-image none luks,_netdev
$ systemctl start 'systemd-cryptsetup@clevis\x2dunlocked.service'
$ grep Id /run/systemd/ask-password/ask*
Before:
$ Id=cryptsetup:clevis-unlocked on /clevis-test-disk-image-mnt
After:
$ Id=cryptsetup:/clevis-test-disk-image
RFC 8080 describes how to use EdDSA keys and signatures in DNSSEC. It
uses the curves Ed25519 and Ed448. Libgcrypt 1.8.1 does not support
Ed448, so only the Ed25519 is supported at the moment. Once Libgcrypt
supports Ed448, support for it can be trivially added to resolve.
The routing policy rule setup logic is moved to the routes setup phase (rather than the addresses setup phase as it is now). Additionally, a call to `link_check_ready` is added to the routing policy rules setup handler. This prevents a race condition with the routes setup handler.
Also give each async handler its own message counter to prevent race conditions when logging successes.
Fixes: #7614
Currently, we accept SERVFAIL after downgrading fully, cache it and move
on. Let's extend this a bit: after downgrading fully, if the SERVFAIL
logic continues to be an issue, then use a different DNS server if there
are any.
Fixes: #7147
On my system the boot and EFI partitions are protected, hence "bootctl
status" can't find the ESP, and then the tool continues with arg_path ==
NULL, which it really should not. Handle these cases, and simply
suppress all output that needs arg_path.
This renames find_esp() to find_esp_and_warn() and tries to normalize its
behaviour:
1. Change the error that is returned when we can't find the ESP to
ENOKEY (from ENOENT). This way the error code can only mean one
thing: that our search loop didn't find a good candidate.
2. Really log about all errors, except for ENOKEY and EACCES, and
document the letter cases.
3. Normalize parameters to the call: separate out the path parameter in
two: an input path and an output path. That way the memory management
is clear: we will access the input parameter only for reading, and
only write out the output parameter, using malloc() memory.
Before the calling convention were quire surprising for internal API
code, as the path parameter had to be malloc() memory and might and
might not have changed.
4. Rename bootctl's find_esp_warn() to acquire_esp(), and make it a
simple wrapper around find_esp_warn(), that basically just adds the
friendly logging for the ENOKEY case. This rework removes double
logging in a number of error cases, as we no longer log here in
anything but ENOKEY, and leave that entirely to find_esp_warn().
5. find_esp_and_warn() now takes a bool flag parameter
"unprivileged_mode", which disables logging in the EACCES case, and
skips privileged validation of the path. This makes the function less
magic, and doesn't hide this internal silencing automatism from the
caller anymore.
With all that in place "bootctl list" and "bootctl status" work properly
(or as good as they can) when I invoke the tools whithout privileges on
my system where /boot is not world-readable
Our CODING_STYLE suggests not comparing with NULL, but relying on C's
downgrade-to-bool feature for that. Fix up some code to match these
guidelines. (This is not comprehensive, the coccinelle output for this
is unfortunately kinda borked)
