* fileio: introduce read_full_virtual_file() for reading virtual files in ↵Franck Bui2019-10-251-1/+1
| | | | | | | | | | | | | | | | | | | sysfs, procfs Virtual filesystems such as sysfs or procfs use kernfs, and kernfs can work with two sorts of virtual files. One sort uses "seq_file", and the results of the first read are buffered for the second read. The other sort uses "raw" reads which always go direct to the device. In the later case, the content of the virtual file must be retrieved with a single read otherwise subsequent read might get the new value instead of finding EOF immediately. That's the reason why the usage of fread(3) is prohibited in this case as it always performs a second call to read(2) looking for EOF which is subject to the race described previously. Fixes: #13585.

| * sd-netlink: constify object pointers passed to gettersZbigniew Jędrzejewski-Szmek2019-10-246-43/+43
| | | | | | | | | | | | | | | | | | sd-netlink is not public yet, so we can change the interface. I did not touch interfaces of functions like sd_netlink_wait() and sd_rtnl_message_new_link() which do not modify the object that is passed in, because in the future we might want to change the code to e.g. take a reference to the parent object or otherwise require a non-const reference.
| * sd-device: allow sd_device_get_devtype to be called with NULL arg and do not ↵Zbigniew Jędrzejewski-Szmek2019-10-241-4/+4
| | | | | | | | | | | | | | assert We shouldn't call assert() on user-specified arguments in public functions. While at it, let's return 1 if the type exists, and 0 otherwise.
* | basic/fs-util: change CHASE_OPEN flag into a separate output parameterZbigniew Jędrzejewski-Szmek2019-10-241-2/+2
|/ | | | | | | | | | | | | chase_symlinks() would return negative on error, and either a non-negative status or a non-negative fd when CHASE_OPEN was given. This made the interface quite complicated, because dependning on the flags used, we would get two different "types" of return object. Coverity was always confused by this, and flagged every use of chase_symlinks() without CHASE_OPEN as a resource leak (because it would this that an fd is returned). This patch uses a saparate output parameter, so there is no confusion. (I think it is OK to have functions which return either an error or an fd. It's only returning *either* an fd or a non-fd that is confusing.)

* | sd-bus: when installing a match make sure not to apply it to already queued ↵Lennart Poettering2019-07-115-7/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | messages This tweaks match installation a bit: the match callbacks are now only called for messages read after the AddMatch() reply was received and never anything already read before. Thus, installing a match gives you a time guarantee: only messages received after it will be matched. This is useful when listening to PropertiesChanged signals as an example to ensure that only changes after the point the match was installed are honoured, nothing before.
* | sd-bus: destroy AddMatch() reply slot in failure case tooLennart Poettering2019-07-111-2/+3
| | | | | | | | | | | | | | | | If AddMatch() doesn't work, let's destroy the slot for it too as soon as we received the failure for it. This way the mere existance of the slot tells us whether the AddMatch() method call is still pending or is complete.
