2012-05-14IB/qib: Fix QLE734X link cyclingMitko Haralanov
The SERDES was using the incorrect Frequency Loop Bandwidth setting causing the link to cycle through the Physical link negotiation state machine. Fixing the Frequency Loop Bandwidth setting in the SERDES helps the link come up faster and more reliably.

2012-05-14IB/qib: Display correct value for number of contextsMitko Haralanov
A "fix" for a bug with the number of contexts on a single-port board caused the calculation to be off by one, which causes problems with the upper layers. The same problem exists for number of free contexts, which is also fixed here.

2012-05-14IB/qib: Correct ordering of reregister vs. port active eventsTodd Rimmer
When a port first goes active with SMA Set(PortInfo) and reregister bit set, the driver sends up the reregister event followed by a port active event. The problem is that in response to reregister event most apps try to issue a SA query of some sort, but that fails because port is not active. The qib driver needs to a trivial change to correct this behavior. This issue has been there for a while; however the recent serdes work has probably made the delay between the reregister event and the active event larger and hence opened the race far enough so that its being seen more often. The patch also changes the clientrereg local to a u8 and saves off the rereg bit into it. The code following the nested subn_get_portinfo() now restores that bit per o14-12.2.1 with a logical OR from that copy.

2012-05-14IB/qib: Optimize pio ack buffer allocationMike Marciniszyn
This patch optimizes pio buffer allocation in the kernel. For qib, kernel pio buffers are used for sending acks. The code to allocate the buffer would always start at 0 until it found a buffer. This means that an average of 64 comparisions were done on each allocate, since the busy bit won't be cleared until the bits are refreshed when buffers are exhausted. This patch adds two new fields in the devdata struct, last_pio and min_kernel_pio. last_pio is the last buffer that was allocated. min_kernel_pio is the lowest potential available buffer. min_kernel_pio is modifed as contexts are allocated and deallocted.

2012-05-14Bluetooth: mgmt: Fix device_connected sending orderJohan Hedberg
The mgmt_ev_device_connected signal must be sent before any event indications happen for sockets associated with the connection. Otherwise e.g. device authorization for the sockets will fail with ENOTCONN as user space things that there is no baseband link. This patch fixes the issue by ensuring that the device_connected event if sent (if it hasn't been so already) as soon as the first ACL data packet arrives from the remote device.

2012-05-14Bluetooth: notify userspace of security level changeGustavo Padovan
It fixes L2CAP socket based security level elevation during a connection. The HID profile needs this (for keyboards) and it is the only way to achieve the security level elevation when using the management interface to talk to the kernel (hence the management enabling patch being the one that exposes this issue). It enables the userspace a security level change when the socket is already connected and create a way to notify the socket the result of the request. At the moment of the request the socket is made non writable, if the request fails the connections closes, otherwise the socket is made writable again, POLL_OUT is emmited.
