If _SOURCE_MONOTONIC_TIMESTAMP was set in the entry, we wouldn't
query the boot ID, leading to every kernel entry in the export mode
to have BOOT_ID=000000000000000. Let's fix this by always querying
the boot ID.
Even if a bonding master interface has carrier, the underlying slave
interfaces may not. In such a case, sending solicitation fails with
-ENOBUS. Here, let's unconditionally ignore errors, as anyway we will
send a solicitation later.
Fixes#24717.
The new conditoins are placed inside of services, but they cannot be
used to test service creds, but only system creds. This deserves
explicit mention, since it might be confusing otherwise.
Reverts a small part of 02380e1946
So far our pam code was using strerror_safe(). But that's not a good approach,
because strerror_safe() is not thread-safe, and the pam code is "library code"
that should be thread-safe. In fact, the whole effort to use strerror() is
unnecessary, because pam_syslog() is documented to support %m. The
implementation in linux-pam simply uses vasprintf(). If we use %m too, we get
rid of the issue. The wrapper sets errno temporarily from the argument.
Apparently some PAM consumers run multiple PAM stacks in threads, so we should
avoid non-thread-safe code.
The new helper returns PAM_BUF_ERR for ENOMEM, and PAM_SERVICE_ERR in other
cases. This may change the returned code in some cases, but I think a) it
doesn't matter much, b) it's probably for the better. E.g. we might now return
PAM_SERVICE_ERR if the dbus message is borked, and PAM_SERVICE_ERR seems
appropriate.
In particular, 'system/service credentials' are now described as simply
'credentials'. The selling point of credentials is that they are transparently
propagated from the system to services, so distinguishing between system and
service credentials is not important.
The description of ordering against initrd-switch-root.target is completely
rewritten. The old description was confused.
I think the description of systemd-measure should be reworked to clearly
describe what new functionality is provided and what policy changes are
built on top. But I don't qrok the details, so I left this part unchanged.
Before Debian switched to systemd, `shutdown now` would reset the system into
single user mode, doing roughly the equivalent of `telinit 1`.
Now, systemd's `shutdown` command does not behave that way; it defaults to
`poweroff` which might be confusing for users (like me) used to the previous
method.
Because I don't use the command often, I keep being stumped by this behavior,
and every time I look at the `shutdown(1)` manpage, I don't understand why I
can't find what I am looking for. This patch should make sure that people like
me find their way back to some sort of reason.
Maybe the *proper* way to fix this would be to restore the more classic
behavior, but I'm definitely not going to climb that hill. Besides, I clearly
remember the time I found out about the `shutdown` command and was *really*
confused when it brought me back to a command-line prompt. That was really
counter-intuitive and I find that change to actually be a good thing. So I'm
not proposing to change this behavior, merely document it better.
I originally added this to the `-P` option but it was suggested adding a new
`COMPATIBILITY` section instead, where other such issues could be added.
The `COMPATIBILITY` section is not actually officially documented. `man(1)`
talks about a `CONFORMING TO` section, but `shutdown(1)` is not
POSIX (`shutdown(2)` is, of course), so there's no actual standard on how this
should work.
The other option I considered was to add a `BUGS` section, but that seemed to
inflammatory, and definitely counter-productive.
In general, log_syntax_internal() must keep errno unchanged. But the
call to log_syntax_callback() was added outside of the block protected
by PROTECT_ERRNO.
--convert writes the journal files read by journalctl to the given
location. The location should be specified as a full journal file
path (e.g. /a/b/c/converted.journal). The directory specifies where
the converted journal files will be stored. The filename specifies
the naming convention the converted journal files will follow.
Previously, we'd iterate an entry array from start to end every time
we added an entry offset to it. To speed up this operation, we cache
the last entry array in the chain and how many items it contains.
This allows the addition of an entry to the chain to be done in
constant time instead of linear time as we don't have to iterate
the entire chain anymore every time we add an entry.
journal_file_data_payload() retrieves the payload of a Data object,
optionally decompressing it and checking to see if matches a given
field. This function replaces all the decompression code in the sd-journal
codebase with a single function.
This commit should not introduce any changes in sd-journal behavior.
To do this, we move EntryItem out of journal-def.h and turn it into
a host only struct in native endian mode so we can still use it to
ship the necessary info around.
Aside from that, the changes are pretty simple, we introduce some
extra functions to access the right field depending on the mode and
convert all the other code to use those functions instead of
accessing the raw fields.
We also drop the unused entry item hash field in compact mode. We
already stopped doing anything with this field a while ago, now we
actually drop it from the format in compact mode.
We also add an environment variable $SYSTEMD_JOURNAL_COMPACT that
can be used to disable compact mode if needed (similar to
$SYSTEMD_JOURNAL_KEYED_HASH).
This adds a new flag in preparation for incompatible journal changes
which will be gated behind this flag. The max file size of journal
files in compact mode is limited to 4 GiB.
