Lennart Poettering e3afaf6b8e sd-bus: rename default bus address constants, they aren't "paths" but "addresses" 2014-11-28 16:17:33 +01:00
Lennart Poettering 3acc1dafd1 sd-bus: add new call sd_bus_get_scope() for querying whether one is connected to a system or a user bus 2014-11-28 16:17:33 +01:00
Lennart Poettering 52cfc0379a sd-bus: rework credential query logic 
Also, make the call to free kdbus slices generic and use it everywhere

Michal Schmidt 279d3c9cea treewide: more log_*_errno() conversions 2014-11-28 14:45:55 +01:00
Michal Schmidt ff49bc3212 treewide: drop unnecessary trailing \n in log_*() calls 2014-11-28 14:26:31 +01:00
Michal Schmidt da927ba997 treewide: no need to negate errno for log_*_errno() 
It corrrectly handles both positive and negative errno values.

Michal Schmidt 0a1beeb642 treewide: auto-convert the simple cases to log_*_errno() 
As a followup to 086891e5c1 "log: add an "error" parameter to all
low-level logging calls and intrdouce log_error_errno() as log calls
that take error numbers", use sed to convert the simple cases to use
the new macros:

find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/'

Multi-line log_*() invocations are not covered.
And we also should add log_unit_*_errno().

Lennart Poettering 412c18f10c sd-bus: the attach_mask kernel module parameter is 64bit now, hence initialize it as such 2014-11-28 02:25:45 +01:00

Lennart Poettering 38ce47e262 sd-bus: when we get the list of well-known names back from kdbus we shouldn't confuse the empty list with unknown information 2014-11-27 22:02:13 +01:00

Alin Rauta be660c371b networkd: fix kernel rtnl receive buffer overrun error 
We got the following error when running systemd on a device  with many ports:

"rtnl: kernel receive buffer overrun
Event source 'rtnl-receive-message' returned error, disabling: No buffer space
available"

I think the kernel socket receive buffer queue should be increased. The default
value is taken from:
"/proc/sys/net/core/rmem_default", but we can overwrite it using SO_RCVBUF
socket option.

This is already done in networkd for other sockets.
For example, the bus socket (sd-bus/bus-socket.c) has a receive queue of 8MB.
In our case, the default is 208KB.

Increasing the buffer receive queue for manager socket to 512KB should be enough
to get rid of the above error.

[tomegun: bump the limit even higher to 8M]

David Herrmann 342f3005f5 bus: prefix custom endpoints with "$UID-" 
The kdbus module will later get a policy that endpoint-names are
restricted to "<uid>-<name>" just like bus-names. Make sure that systemd
is already compatible to that.

Lennart Poettering cf226cfc24 sd-bus: make sure that when we connect to the system bus we have enough creds to make security decisions 2014-11-26 18:59:31 +01:00
Lennart Poettering d108ddf172 sd-bus: update kdbus.h from upstream 2014-11-26 15:43:50 +01:00
Lennart Poettering e12d81ae80 sd-bus: given that the kernel now passes the auxgroups list as 32bit array to us, no need to convert to uid_t manually 
This way, we can save one allocation and avoid copying the array
unnecesarily.

David Herrmann affc7fe9e1 bus: update kdbus.h (ABI break) 
We changed creds to u32, so fix systemd sd-bus to acknowledge that.

Lennart Poettering 38813cc824 bus-kernel: when installing an activator, ask for any kind of metadata to be attached to incoming messages 
We don't know what the activated service might want in the end, hence
enable everything current and future, just to be sure.

Lennart Poettering 8aee3fc7ea sd-bus: don't clobber return values on failure in bus_kernel_open_bus_fd() 2014-11-26 03:06:50 +01:00
Lennart Poettering fa7796e97b sd-bus: set per-bus attach flag requirement mask to ANY 
On the system and user busses we create it's the receiver that chooses
which metadata is attched, not the sender, hence set the requirement
mask to ANY, to allow any current of future credential bit to be
attached.

Lennart Poettering b5dae4c7f7 sd-bus: add suppot for renegotiating message credential attach flags 2014-11-26 02:20:55 +01:00
Lennart Poettering f3c0588651 sd-bus: use free_and_strdup() where appropriate 
This simplifies things a bit and makes sure we free any previously set
creds component before writing in a new one.

Lennart Poettering 40ed1a4574 busctl: add new --augment-creds= switch for controlling whether shown credential data shall be augment with data from /proc 2014-11-25 14:28:34 +01:00
Lennart Poettering 705a415f68 sd-bus: update to current kernel version, by splitting off the extended KDBUS_ITEM_PIDS structure from KDBUS_ITEM_CREDS 
Also:

- adds support for euid, suid, fsuid, egid, sgid, fsgid fields.

- makes augmentation of creds with data from /proc explicitly
  controllable to give apps better control over this, given that this is
  racy.

- enables augmentation for kdbus connections (previously we only did it
  for dbus1). This is useful since with recent kdbus versions it is
  possible for clients to control the metadata they want to send.

- changes sd_bus_query_sender_privilege() to take the euid of the client
  into consideration, if known

- when we don't have permissions to read augmentation data from /proc,
  don't fail, just don't add the data in
