Catch up with latest changes in kdbus.ko:
* Signals can be sent as unicast now, hence they need to be marked as
such with the KDBUS_MSG_SIGNAL in the message flags.
* Follow ioctl number change for KDBUS_CMD_FREE

When setting up a namespace, mount flags like noexec, nosuid and
nodev are cleared, so the mounts always have exec, suid and dev
flags enabled.
Copy source directory mount flags to target mount when remounting
the bind mounts.

We always should use the same checks when deciding whether swap support
and mounting of devices is supported. Hence, let's make
fstab-generator's logic more similar to the usual logic we follow:
a) Look for /proc/swaps and no container support before activating
swaps.
b) Look for /sys being writable befire supporting device mounts.

Regression introduced by ed757c0cb03eef50e8d9aeb4682401c3e9486f0b
Mirror the implementation of columns(), since the fd_columns()
functions returns a negative integer for errors.
Also fix columns() to return the unsigned variable instead of the
signed intermediary (they're the same, but better to be explicit).

journal file headers
Since the file headers might be replaced by zeroed pages now due to
sigbus we should make sure we don't end up dividing by zero because we
don't check values read from journal file headers for changes.

arguments should be prefixed with "arg_"

This makes them robust regarding truncation. Ideally, we'd export this
as an API, but given how messy SIGBUS handling is, and the uncertain
ownership logic of signal handlers we should not do this (unless libc
one day invents a scheme how to sanely install SIGBUS handlers for
specific memory areas only). However, for now we can still make all our
own tools robust.
Note that external tools will only have read-access to the journal
anyway, where SIGBUS is much more unlikely, given that only writes are
subject to disk full problems.

Even though we use fallocate() it appears that file systems like btrfs
will trigger SIGBUS on certain low-disk-space situation. We should
handle that, hence catch the signal, add it to a list of invalidated
pages, and replace the page with an empty memory area. After each write
check if SIGBUS was triggered, and consider the write invalid if it was.
This should make journald a lot more robust with file systems where
fallocate() is not reliable, for example all CoW file systems
(btrfs...), where changing written data can fail with disk full errors.

for the container's own subtree in the name=systemd hierarchy
More specifically mount all other hierarchies in their entirety and the
name=systemd above the container's subtree read-only.

Reporter says he incorrectly measured the data but the device is not available
anymore to correct it. We'll have to wait for someone else to submit the data.

Looks like a typo when introduced in fefdc04b38725457a91651218feb7000f6ccc1f4

By analogy with commit 4038d7502f.

-n is only allowed for root. /etc/mtab is nowadays almost always a link to /proc/,
so in practice this does not really matter too much, but should allow .mount units
to work in --user mode.

Those values are based on a file we read from disk, so we should
verify everything we receive, and make sure everything we print
is sensible.
Also, print fractional seconds for TTL.

usec_t is defined as 64 bit wide, but long is 32 bit on many archs.

systemd.pc contains "libdir" which can be architecture specific. Thus it needs
to be installed into libdir/pkgconfig/ instead of datadir/pkgconfig.
As nothing else is using pkgconfigdata any more, remove it entirely.
Note that udev.pc does not contain architecture specific values and thus can be
kept in /usr/share/pkgconfig/.

It carries no additional information and forces a passive sentence
structure which is longer and harder to parse.

[zj: change "in into" to "into".]

When doing "make clean" the unit/machines.target file gets deleted.
This causes a build error later on when trying to rebuild systemd.
V2: The file probably belongs to dist_systemunit_DATA

See bug 87859 (https://bugs.freedesktop.org/show_bug.cgi?id=87859). Bug
reporter found the language describing the effect of specifying both a
day and date unclear; hopefully the attached patch will clarify and
allow the bug to be closed.

Fix a bunch of needless memzero() calls, a bunch of use-after-free
regarding _cleanup_free_ and drop unused variables.
Hint: Do NOT use _cleanup_free_ for temporary strappend() helpers that are
freed multiple times. All you safe is the last free() call, which is
really not worth the trouble resetting it to NULL all the time.
|
|
Another uninitialized variable marked as _cleanup_. Set it to NULL to
avoid accessing uninitialized memory.
|
|
Make sure to set _cleanup_ variables to NULL. Otherwise, we free
uninitialized objects.
|
|
Make sure to actually free the underlying object in CurlGlue unref.
|
|
'k' is marked as _cleanup_free_ so reset it to NULL if we free it
explicitly.
|
|
Make sure to test the right variable for NULL.
|
|
Make sure malloc() really returns non-NULL in lldp test.
|
|
'r' is not touched after the previous error-checking 100 lines above. Drop
that code.
