Lennart Poettering 693eb9a2d4 bus: rename message "serial" to "cookie" 
Even if the lower-leveld dbus1 protocol calls it "serial", let's expose
the word "cookie" for this instead, as this is what kdbus uses and since
it doesn't imply monotonicity the same way "serial" does.

Lennart Poettering 751bc6ac79 bus: properly shift cgroup data returned from kdbus by the container's root before parsing 2013-12-24 19:31:44 +01:00
Lennart Poettering 2dc9970bed bus: only accept kdbus creds if they are valid 
This allows userspace to fake kdbus creds via struct ucred in the proxy,
without making the recieving side choke on the missing fields of the
kdbus struct, more precisel pid_starttime and tid

Lennart Poettering 0721804f03 bus: send status message from proxyd to systemd about client we are working for 2013-12-21 05:15:09 +01:00
Lennart Poettering 85a0aa17dd bus: when watching bus names, we always need to add a change match 
Since for the kernel change of ownership of a name between starter and
real client is a change and for userspace thats addition/removal, we
need to unconditionally subscribe to these change events.

Given that the kernel does not validate bus names we have to when using
them.

Daniel Mack ceceaf09f9 bus: sync with kdbus 
Two new things here:

a) struct kdbus_notify_name_change now carries two struct
   kdbus_notify_id_change

b) a new KDBUS_CMD_BYEBYE ioctl that has no user yet in systemd

Lukasz Skalski 043ccd8383 libsystemd-bus: the same error codes for sd_bus_release_name() (for kdbus and dbus1) 
Due to this patch, sd_bus_release_name() function
returns the same code errors for kdbus and dbus1
if we try release non-existing name or foreign
name.

Lennart Poettering 29a07cdb4a bus: instead of exposing the dbus1 flags when acquiring a name use our own that are closer to kdbus 
This turns around DO_NOT_QUEUE into QUEUE which implies a more useful
default. (And negative options are awful anyway.)

Lennart Poettering 0461f8cdc1 bus: internalize a lot of protocol definitions 
We shouldn export what isn't necessary or useful to clients, so let's
add the protocol definitions we only need internally into a private
header.

Lennart Poettering e7176abbe8 bus: make sd_bus_request_name() and sd_bus_release_name() behave more like other calls 
Instead of returning an enum of return codes, make them return error
codes like kdbus does internally.

Also, document this behaviour so that clients can stick to it.

(Also rework bus-control.c to always have to functions for dbus1 vs.
kernel implementation of the various calls.)

Lennart Poettering 95c4fe8271 busctl: add command to dump creds of a peer or pid 
(also, rename _SD_BUS_CREDS_MAX to _SD_BUX_CRED_ALL, since "MAX" so far
was used to indicate one higher than the highest valid value, and this
is not correct here.)

Daniel Mack 1d0e3c9884 libsystemd-bus: catch up with latest kdbus changes 
The name list and query functions now work differently in kdbus, as the
result is stored in the connection's pool, rather than being copied back
through the ioctl buffer. That also safes us some logic, as we don't
have to resize the communication buffer in a loop with growing buffer
sizes.

Due to this, KDBUS_CMD_MSG_RELEASE was renamed to KDBUS_CMD_FREE, as it
is now used outside the message logic as well.

Daniel Mack ed99569df8 libsystemd-bus: sd_bus_request_name: fix return value for kdbus 
kdbus returns -EALREADY if the requesting connection is already the
owner of a name, and -EEXIST if the name already exists and the
connection is not able to take it over.

Also, n->flags needs a translation as well to match the SD_BUS_* enum
values.
