2014-10-25smack: never follow symlinks when relabellingLennart Poettering
previously mac_smack_apply(path, NULL) would operate on the symlink itself while mac_smack_apply(path, "foo") would follow the symlink. Let's clean this up an always operate on the symlink, which appears to be the safer option. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2014-10-25smack: rework smack APIs a bitLennart Poettering
a) always return negative errno error codes b) always become a noop if smack is off c) always take a NULL label as a request to remove it Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-10-25hashmap: introduce hashmap_reserve()Michal Schmidt
With the current hashmap implementation that uses chaining, placing a reservation can serve two purposes: - To optimize putting of entries if the number of entries to put is known. The reservation allocates buckets, so later resizing can be avoided. - To avoid having very long bucket chains after using hashmap_move(_one). In an alternative hashmap implementation it will serve an additional purpose: - To guarantee a subsequent hashmap_move(_one) will not fail with -ENOMEM (this never happens in the current implementation).

2014-10-25shared/log: add log_trace as compile-time optional debuggingZbigniew Jędrzejewski-Szmek
Repetetive messages can be annoying when running with SYSTEMD_LOG_LEVEL=debug, but they are sometimes very useful when debugging problems. Add log_trace which is like log_debug but becomes a noop unless LOG_TRACE is defined during compilation. This makes it easy to enable very verbose logging for a subset of programs when compiling from source. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-10-25hwdb: Add mapping for special keys on compaq ku 0133 keyboardsHans de Goede
The compaq ku 0133 keyboard has 8 special keys at the top: http://lackof.org/taggart/hacking/keyboard/cpqwireless.jpg 3 of these use standard HID usage codes from the consumer page, the 5 others use part of the reserved 0x07 - 0x1f range. This commit adds mapping for this keyboard for these reserved codes, making the other 5 keys work.

2014-09-30Do not format USEC_INFINITY as NULLZbigniew Jędrzejewski-Szmek
systemctl would print 'CPUQuotaPerSecUSec=(null)' for no limit. This does not look right. Since USEC_INFINITY is one of the valid values, format_timespan() could return NULL, and we should wrap every use of it in strna() or similar. But most callers didn't do that, and it seems more robust to return a string ("infinity") that makes sense most of the time, even if in some places the result will not be grammatically correct.

2014-09-24test: udev - restrict nemuric uid's to existing onesTom Gundersen

2014-09-18src/udev/udev-node.c: replace our error handling with upstreamsAnthony G. Basile
eudev has had this error handling for a while. upstream finally added it with the following commit 543afdc63c02a5af3cf6bd2a264162f23474346a by Tom Gundersen <teg@jklm.no>. Both methods are equivalent, but we adopt upstreams for easier maintenance. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-09-18udev: fix path for database names on 'change' eventRobert Milasan
If a device does not have a major/minor number attached, we use different database names than if it does. On "change" events, we didn't copy the devnum over, therefore, we used different paths than on 'add' or 'remove' events (where devnum was properly copied). Fix this by always copying the devnum into the udev-device. (David: added commit-log from email) Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
