ISO/IEC 9899:1999 §7.21.1/2 says:
Where an argument declared as size_t n specifies the length of the array
for a function, n can have the value zero on a call to that
function. Unless explicitly stated otherwise in the description of a
particular function in this subclause, pointer arguments on such a call
shall still have valid values, as described in 7.1.4.
In base64_append_width memcpy was called as memcpy(x, NULL, 0). GCC 4.9
started making use of this and assumes This worked fine under -O0, but
does something strange under -O3.
This patch fixes a bug in base64_append_width(), fixes a possible bug in
journal_file_append_entry_internal(), and makes use of the new function
to simplify the code in other places.

Just a clarification. At least systemd-openqa-generator from
openqa gets this wrong.
|
|
Saying it is the "default" is misleading, because it is almost
never used.
|
|
All distribution-specific code was removed ages ago.
|
|
Repeating those conditionals for every program is
annoying. Use a helper variable to avoid conditionals.
Also always add generated completion files to CLEANFILES.
|
|
It's better to always include them in 'make clean'.
It is also easier to read Makefile.am when less stuff is conditional.

tmpfiles: drop /run/lock/lockdev
|
|
Hardly any software uses that any more, and better locking mechanisms like
flock() have been available for many years.
Also drop the corresponding "lock" group from sysusers.d/basic.conf.in, as
nothing else is using this.

|
Expose additional booleans in sd_journal and improve error messages in journalctl
|
|
|
|
Make it clear that specifing boot when there is actually only one has no
effect. This cosmetic patch improves user experience a bit.
|
|
Also introduce sd_journal_has_runtime_files() and
sd_journal_has_persistent_files() to the public API. These functions
can be used to easily find out if the open journal files are runtime
and/or persistent.

Resolved 2

basic: fix touch() creating files with 07777 mode
|
|
mode_t is unsigned, so MODE_INVALID < 0 can never be true.
This fixes a possible DoS where any user could fill /run by writing to
a world-writable /run/systemd/show-status.

I'm not defining _DNS_SERVER_TYPE_MAX/INVALID as usual in the enum,
because it wouldn't be used, and then gcc would complain that
various enums don't test for _DNS_SERVER_TYPE_MAX. It seems better
to define the macro rather than add assert_not_reached() in multiple
places.
|
|
For consistency, generic.size is renamed to generic.data_size.
nsec3.next_hashed_name comparison was missing a size check.
|
|
|
|
This mirrors the behaviour of host and makes the conversion to and from
string symmetrical.

The commmon case default qeth link is enccw0.0.0600 is rather long.
Thus strip leading zeros (which doesn't make the bus_id unstable),
similar to the PCI domain case.
Also 'ccw' is redundant on S/390, as there aren't really other buses
available which could have qeth driver interfaces. Not sure why this
code is even compiled on non-s390[x] platforms. But to distinguish from
e.g. MAC stable names shorten the suffix to just 'c'.
Thus enccw0.0.0600 becomes enc600.
