2014-09-25bus-proxy: drop one wrong assert()Tom Gundersen
2014-09-25shared: path-util - try to make PATH_FORECH_PREFIX look less wrongTom Gundersen
We replace the idiom "X && !(*foo = 0)" with "X && ((*foo = 0), true)". This is not a functional change, but should hopefully make it less likely that people and static analyzers believe there is a typo here (i.e., to make it clear that the intention was not "X && *foo != 0"). Thanks to David Herrmann for the suggestion.
2014-09-25bus-proxyd: add some assertsTom Gundersen
Both as documentation, and to make Coverity happy. Fixes CID #1241495 and #1241496.
2014-09-25localectl: print warning when there are options given on kernel cmdlineMichal Sekletar
2014-09-25fileio: make parse_env_file() return number of parsed itemsMichal Sekletar
This commit introduces possibility to call parse_env_file_internal() and hand over extra argument where we will accumulate how many items were successfully parsed and pushed by callback. We make use of this in parse_env_file() and return number of parsed items on success instead of always returning zero. As a side-effect this commit should fix bug that locale settings in /etc/locale.conf are not overriden by options passed via kernel command line.
2014-09-24bus-policy: split API for bus-proxydDaniel Mack
Instead of operating on an sd_bus_message object, expose an API that has 4 functions: policy_check_own() policy_check_hello() policy_check_recv() policy_check_send() This also allows dropping extra code to parse message contents - the bus proxy already has dedicated code paths for that, and we can hook into those later. Tests amended accordingly.
2014-09-23bus: remove unused checkThomas Hindoe Paaboel Andersen
strerror_r does not return null here and even if it did we would have problems already at the preceding strlen call. Found by coverity. Fixes: CID#1237770
2014-09-23terminal: provide display dimensions to API usersDavid Herrmann
Allow users to query the display dimensions of a grdev_display. This is required to properly resize the objects to be rendered.
2014-09-23terminal: verify kernel-returned DRM events are not truncatedDavid Herrmann
Make sure the kernel always returns events properly. This is guaranteed right now, otherwise, we do something really wrong. But lets be sure and verify the received values properly. This also silences some coverity warnings.
2014-09-23terminal: verify grdev tiles are correctly linkedDavid Herrmann
We used to set "pipe->tile = tile" inside of the leaf allocation. We no longer do that. Verify that "out" is non-NULL, otherwise we'd leak memory. This is currently always given, but make sure to add an assert(), so coverity does not complain.
2014-09-23terminal: fix tile-offset calculationDavid Herrmann
Binary operators with two pointers as arguments always operate on object-size, not bytes. That is, "int *a, *b", (a - b) calculates the number of integers between b and a, not the number of bytes. Fix our cache-offset calculation to not use sizeof() with full-ptr arithmetic.
2014-09-23Silence some "unchecked return-value" warningsDavid Herrmann
This adds some log-messages to ioctl() calls where we don't really care for the return value. It isn't strictly necessary to look for those, but lets be sure and print warnings. This silences gcc and coverity, and also makes sure we get reports in case something goes wrong and we didn't expect it to fail that way.
2014-09-23sd-bus: sync kdbus.hDaniel Mack
2014-09-23sd-bus: sync kdbus.h (API break)Daniel Mack
Just a rename of two struct members to make the header file c++ compatible.
2014-09-23localed: rename write_data_x11 to x11_write_dataZbigniew Jędrzejewski-Szmek
Other functions in this file follow this pattern, we have vconsole_write_data and locale_write_data.
2014-09-23Fix warning about unused variable with !SELINUXZbigniew Jędrzejewski-Szmek
src/shared/label.c:255:15: warning: unused variable 'l' [-Wunused-variable] char *l = NULL; ^
2014-09-23terminal: fix spelling mistakeZbigniew Jędrzejewski-Szmek
2014-09-22logind: add support for Triton2 Power ButtonZbigniew Jędrzejewski-Szmek

2014-09-22sd-bus: sync kdbus.h (API+ABI break)Daniel Mack
The kdbus logic name registry logic was changed to transport the actual name to acquire, release or report in a kdbus item. This brings the name API a little more in line with other calls, and allows for later augmentation. Follow that change on the systemd side.
2014-09-22util: avoid non-portable __WORDSIZEEmil Renner Berthing
Lets not unnecessarily rely on __WORDSIZE, which is not clearly specified by any spec. Use explicit size comparisons if we're not interested in the WORDSIZE, anyway. (David: adjust commit message to explain why we do this)
2014-09-22terminal: signal object removal during sysview_context_stop()David Herrmann
Now that we no longer propagate callback return values, we can safely call into user-callbacks during sysview_context_stop(). This way, users can rely on all objects to be removed via callbacks (except if they failed during object creation). This avoids duplicating any object hashtables on the users' side and reduces memory consumption.
2014-09-22terminal: handle callback errors in sysview instead of propagating themDavid Herrmann
We cannot sanely propagate error codes if we call into user-callbacks multiple times for multiple objects. There is no way to merge those errors or somehow propagate them. However, we can just act similar to sd-event and print a log-message while discarding the values. This way, we allow error-returns, but can properly continue working on our objects.
2014-09-22terminal: allow user-context to be retrieved/storedDavid Herrmann
Add "userdata" storage to a bunch of external objects, namely displays and sessions. Furthermore, add some property retrieval helpers. This is required if we want external API users to not duplicate our own object hashtables, but retrieve context from the objects themselves.
2014-09-22terminal: make evdev logind-matches per sessionDavid Herrmann
Instead of adding matches per device, we now add logind matches per session. This reduces the number of matches considerably and saves resources.
2014-09-22exit-status.c: bring EXIT_BUS_ENDPOINT label in line with othersZbigniew Jędrzejewski-Szmek
2014-09-22man: fix typo and add linkZbigniew Jędrzejewski-Szmek
2014-09-22login: add public sd_session_get_desktop() APIDavid Herrmann
The desktop brand is stored as DESKTOP variable for sessions. It can be set arbitrarily by the session owner and identifies the desktop environment that is running on that session.
2014-09-22bus: align kdbus ioctl parameters to 8byteDavid Herrmann
All kdbus ioctl arguments must be 8byte aligned. Make sure we use alloca_align() and _alignas_(8) in all situations where gcc doesn't guarantee 8-byte alignment. Note that objects on the stack are always 8byte aligned as we put _alignas_(8) into the structure definition in kdbus.h.
2014-09-22util: add alloca_align()David Herrmann
The alloca_align() helper is the alloca() equivalent of posix_memalign(). As there is no such function provided by glibc, we simply account for additional memory and return a pointer offset into the allocated memory to grant the alignment. Furthermore, alloca0_align() is added, which simply clears the allocated memory.
2014-09-22test-util: make valgrind happyDavid Herrmann
Properly free all temporary resources to make valgrind not complain about lost records.
2014-09-22terminal: raise sysview DEVICE_CHANGE events per attachmentDavid Herrmann
Instead of raising DEVICE_CHANGE only per device, we now raise it per device-session attachment. This is what we want for all sysview users, anyway, as sessions are meant to be independent of each other. Lets avoid any external session iterators and just do that in sysview itself.
2014-09-22terminal: forward evdev RESYNC events to linked devicesDavid Herrmann
Whenever we resync an evdev device (or disable it), we should send RESYNC events to the linked upper layers. This allows to disable key-repeat and assume some events got dropped.
2014-09-22terminal: always call _enable/_disable on evdev devicesDavid Herrmann
The current pause/resume logic kinda intertwines the resume/pause and enable/disable functions. Lets avoid that non-obvious behavior and always make resume call into enable, and pause call into disable, if appropriate.
2014-09-22terminal: print RESYNC state in evcatDavid Herrmann
Whenever a key-event is part of a RESYNC, we should print that verbosely as those events are out-of-order.
2014-09-20bus-policy: add test utilityDaniel Mack
Add some test files and routines for dbus policy checking.
2014-09-20bus-policy: add policy check functionDaniel Mack
Add policy_check() to actually check whether an incoming message is allowed by the policy. The code is not yet used from the proxy daemon, though.
2014-09-20bus-policy: print numeric [gu]id in dump_items()Daniel Mack
2014-09-20bus-policy: do not exit() from policy_dump()Daniel Mack
This function is quite useful for debugging. Exiting from it seems unnecessary.
2014-09-20bus-policy: implement dump_items() with LIST_FOREACHDaniel Mack
Instead of making the function call itself recursively.
2014-09-20bus-policy: resolve [ug]id of POLICY_ITEM_{USER,GROUP}Daniel Mack
Do the lookup during parsing already, and set i->uid, or i->gid to the numerical values.
2014-09-20bus_policy: set i->[ug]id_validDaniel Mack
2014-09-20bus-policy: append items rather than prepending themDaniel Mack
In the D-Bus policy, the order of items matters, so make sure to store them in the same order as they are parsed by the sax parser.
2014-09-20bus-policy: story mandatory items in right listDaniel Mack
2014-09-20test: udev - restrict nemuric uid's to existing onesTom Gundersen
We now verify the existence of uid's before applying them to devicenodes, so change the test accordingly. We assume that both uid/gid 1 and 2 exist on the test system.
2014-09-20terminal: fix mode sync for connectorsDavid Herrmann
The GETXY ioctls of DRM are usually called twice by libdrm: Once to retrieve the number of objects, a second time with suitably sized buffers to actually retrieve all objects. In grdrm, we avoid these excessive calls and instead just call ioctls with cached buffers and resize them if they were too small. However, connectors need to read the mode list via EDID, which is horribly slow. As the kernel still cannot do that asynchronously (seriously, we need to fix this!), it has a hack to only do it if count_modes==0. This is fine with libdrm, as it calls every ioctl twice, anyway. However, we fail horribly with this as we usually never pass 0. Fix this by calling into GETCONNECTOR ioctls twice in case we received an hotplug event. Only in those cases, we need to re-read modes, so this should be totally fine.
2014-09-20terminal: restructure some logging calls in grdrmDavid Herrmann
Multiple issues here: 1) Don't print excessive card dumps on each resync. Disable it and make developers add it themselves. 2) Ignore EINVAL on page-flips. Some cards don't support page-flips, so we'd print it on each frame. Maybe, at some point, the kernel will add support to retrieve capabilities for that. Until then, simply ignore it. 3) Replace the now dropped card-dump with a short message about resyncing the card.
2014-09-20terminal: grdev: schedule virtual frame events if hw doesn't support itDavid Herrmann
Whenever we cannot use hardware frame events, we now schedule a virtual frame event to make sure applications don't have to do this. Usually, applications render only on data changes, but we can further reduce render-time by also limiting rendering to vsyncs.
2014-09-20terminal: grdev: raise frame event after DISPLAY_ADD/CHANGEDavid Herrmann
Whenever a display is added or changed, we suppressed any frame events. Make sure to raise them manually so we can avoid rendering when handling anything but FRAME events.
2014-09-20terminal: split grdrm_crtc_commit() apartDavid Herrmann
This helper is quite huge, split it apart to make it easier to follow.
