2014-10-28benchmark: cache the kdbus msg and update only memfd item offset if neededDjalal Harouni1-31/+99
No need to create the kdbus msg every time, and if we are sending a memfd, then just store its item offset, patch it later with the right memfd fd+data, seal it, then send it. Signed-off-by: Djalal Harouni <tixxdz@opendz.org>

2014-10-27kdbus.h, metadata: factor out capabilities (ABI break)Daniel Mack1-8/+9
Move capabilites to its own struct inside kdbus_item. This also gives us the ability to inform userspace of the highest caps bit the kernel knows about. Hence, if the capabilites grow in either the number of sets or the number of rows, we can now detect and handle both from userspace. Signed-off-by: Daniel Mack <daniel@zonque.org>

2014-10-23connection: keep SYNC messages alive on EINTRDavid Herrmann1-20/+19
If a SYNC-SEND is interrupted by a signal, there is no way we can restart the syscall. If we returned ERESTARTSYS, we'd queue the message again on restart. This is very irritating, therefore, we never support restarting syscalls. Instead, we return EINPROGRESS if the message was queued but no reply was received, yet. Internally, we turn the 'sync' reply_wait into an 'async' reply. This way, it will be treated the same way as any other asynchronous reply. Signed-off-by: David Herrmann <dh.herrmann@gmail.com>

2014-10-22kdbus.h: rename kdbus_{cmd,}_conn_info → kdbus_{cmd,}_infoDaniel Mack5-10/+10
As we now use kdbus_cmd_conn_info and kdbus_conn_info for bus creator information as well, rename the structs to a more generic term. Signed-off-by: Daniel Mack <daniel@zonque.org>
2014-10-22kdbus.h: add KDBUS_CMD_BUS_CREATOR_INFODaniel Mack3-77/+118
Add a call to return metadata on the task that created a bus, at the moment it did so. The call behaves similar to KDBUS_CMD_CONN_INFO, and shares the same dispatcher code in handle.c. While at it, factor out bus-related test functions to their own file, and also add some code test the new ioctl. Signed-off-by: Daniel Mack <daniel@zonque.org>
2014-10-22test-fd: add a bloom filter to broadcast messageDaniel Mack1-4/+12
Satisfy a kernel check so we can be sure we really bail out due to the check we're actually enforcing. Signed-off-by: Daniel Mack <daniel@zonque.org>

2014-10-22test-sync: do a second recv only when SA_RESTART was passedDjalal Harouni1-1/+1
The test was working for all cases, but fix it to only check for the SA_RESTART case. Signed-off-by: Djalal Harouni <tixxdz@opendz.org>
2014-10-22test: use kdbus_msg_dump() to check for message integrityDaniel Mack2-5/+15
Make kdbus_msg_dump() return an error in case there's anything wrong with the message. Return such errors from kdbus_msg_recv(). We currently fail with notifications. Signed-off-by: Daniel Mack <daniel@zonque.org>
2014-10-21connection: switch to absolute timeouts (API break)Daniel Mack1-1/+10
Make the timeouts in struct kdbus_msg.timeout_ns absolute. This is necessary in order to support blocking sync calls with SA_RESTART behavior. Signed-off-by: Daniel Mack <daniel@zonque.org>
2014-10-21test-sync: implement send_reply()Daniel Mack1-1/+48
Implement a new helper function to reply to pending messages. Formerly, the test abused the timeout parameter to respond, knowing that its value will eventually end up in the kdbus message in the same union as the cookie_reply field. In the process of switching to absolute timeouts, however, this bites us, so move this hack out of the way first. Signed-off-by: Daniel Mack <daniel@zonque.org>
2014-10-21kdbus.h: split in and out flags of ioctls (ABI break)Daniel Mack4-21/+8
Instead of negotating kernel flags via the same field for input and output, use two different bitfields for that, and call the returned flags 'kernel_flags'. The approach implemented before didn't turn out to work too well for more complex userspace programs that retain the same ioctl buffers for multiple calls, and which had to manually save and restore the flags before. While at it, rename conn_flags → flags in kdbus_cmd_hello to ease the internal helper functions and unify the API a bit more. Signed-off-by: Daniel Mack <daniel@zonque.org>
2014-10-21kdbus.h: factor out name info struct (ABI break)Daniel Mack2-2/+2
Introduce struct kdbus_name_info and report information on name lists with it, instead of (ab)using struct kdbus_cmd_name for it. That way, we can get rid of two fields in the latter. Signed-off-by: Daniel Mack <daniel@zonque.org>

2014-10-18tree-wide: rework flags negotiation (ABI break)Daniel Mack3-3/+17
We are obliged to reject all bits in flags fields that are not known to the kernel. In order to let userspace know which flags the kernel knowns about, we agreed to always write back to the flags field in the ioctl buffer, even if the call succeeded. The kernel will, however, will always set the KDBUS_FLAG_KERNEL bit, which consequently is always invalid when submitted by userspace. Move some checks from other place to handle.c, and update the testsuite and documentation accordingly. Signed-off-by: Daniel Mack <daniel@zonque.org>
2014-10-17Revert KDBUS_HELLO_ACCEPT_MEMFD support (ABI break)Kay Sievers2-6/+7
Memfds are a basic exchange mechanism not supposed to be optional per connection. A per-bus flag, instead of a per-connection one, would probably be acceptable, but its usefulness is questionable at this point. Broadcasts can contain memfds and we would silently messages for such connections, which is not the expected behavior. Receivers just need to make sure to be able to receive messages with memfd payload, otherwise they are just not fully supporting the common kdbus interface. Contracts of not supporting memfds on private buses are fine, but the general purpose communication will always require memfds to be supported by all clients.

2014-10-08kdbus.h: add features bitmask to cmd_make and cmd_hello (ABI BREAK)Daniel Mack1-1/+7
Add a new field called 'features' to struct kdbus_cmd_make and kdbus_cmd_hello. In these bitmasks, userspace can request features from the kernel, and the kernel can itself request features from userspace. For now, we check that this field is set to 0, and bail with -EOPNOTSUPP otherwise. Signed-off-by: Daniel Mack <daniel@zonque.org>
