2012-01-09binder: Fix memory corruption via page aliasingChristopher Lais
binder_deferred_release was not unmapping the page from the buffer before freeing it, causing memory corruption. This only happened when page(s) had not been freed by binder_update_page_range, which properly unmaps the pages. This only happens on architectures with VIPT aliasing. To reproduce, create a program which opens, mmaps, munmaps, then closes the binder very quickly. This should leave a page allocated when the binder is released. When binder_deferrred_release is called on the close, the page will remain mapped to the address in the linear proc->buffer. Later, we may map the same physical page to a different virtual address that has different coloring, and this may cause aliasing to occur. PAGE_POISONING will greatly increase your chances of noticing any problems. Change-Id: I6941bf212881b8bf846bdfda43d3609c7ae4892e Signed-off-by: Christopher Lais <chris+android@zenthought.org>

2012-01-09PM: runtime: add might_sleep to PM runtime functionsColin Cross
The list of functions that can be called in atomic context is non-intuitive (pm_runtime_put_sync can not, but pm_runtime_put_sync_suspend can, if pm_runtime_irq_safe has been called?). The code is actively misleading - the entry points all start with spin_lock_irqsave, suggesting they are safe to call in atomic context, but may later enable interrupts. Add might_sleep_if to all the __pm_runtime_* entry points to enforce correct usage. Also add pm_runtime_put_sync_autosuspend to the list of functions that can be called in atomic context.

2012-01-09cpuidle: governor: menu: don't use loadavgColin Cross
get_loadavg doesn't work as intended. According to the comments, it should be returning an average over a few seconds, but it is actually reading the instantaneous load. It is almost always returning 0, but can sometimes, depending on workload, spike very high into the hundreds even when the average cpu load is under 10%. Disable it for now.

2012-01-09Bluetooth: Fix l2cap conn failures for ssp devicesPeter Hurley
Commit 330605423c fixed l2cap conn establishment for non-ssp remote devices by not setting HCI_CONN_ENCRYPT_PEND every time conn security is tested (which was always returning failure on any subsequent security checks). However, this broke l2cap conn establishment for ssp remote devices when an ACL link was already established at SDP-level security. This fix ensures that encryption must be pending whenever authentication is also pending. Change-Id: I6876ea5134e90d1f3d0f84e8ed40b92977b3df64 Signed-off-by: Peter Hurley <peter@xxxxxxxxxxxxxxxxxx>

2012-01-09Bluetooth: Allow SCO/eSCO packet type selection for outgoing SCO connections.Nick Pelly
__u16 sco_pkt_type is introduced to struct sockaddr_sco. It allows bitwise selection of SCO/eSCO packet types. Currently those bits are: 0x0001 HV1 may be used. 0x0002 HV2 may be used. 0x0004 HV3 may be used. 0x0008 EV3 may be used. 0x0010 EV4 may be used. 0x0020 EV5 may be used. 0x0040 2-EV3 may be used. 0x0080 3-EV3 may be used. 0x0100 2-EV5 may be used. 0x0200 3-EV5 may be used. This is similar to the Packet Type parameter in the HCI Setup Synchronous Connection Command, except that we are not reversing the logic on the EDR bits. This makes the use of sco_pkt_tpye forward portable for the use case of white-listing packet types, which we expect will be the primary use case. If sco_pkt_type is zero, or userspace uses the old struct sockaddr_sco, then the default behavior is to allow all packet types. Packet type selection is just a request made to the Bluetooth chipset, and it is up to the link manager on the chipset to negiotiate and decide on the actual packet types used. Furthermore, when a SCO/eSCO connection is eventually made there is no way for the host stack to determine which packet type was used (however it is possible to get the link type of SCO or eSCO). sco_pkt_type is ignored for incoming SCO connections. It is possible to add this in the future as a parameter to the Accept Synchronous Connection Command, however its a little trickier because the kernel does not currently preserve sockaddr_sco data between userspace calls to accept(). The most common use for sco_pkt_type will be to white-list only SCO packets, which can be done with the hci.h constant SCO_ESCO_MASK. This patch is motivated by broken Bluetooth carkits such as the Motorolo HF850 (it claims to support eSCO, but will actually reject eSCO connections after 5 seconds) and the 2007/2008 Infiniti G35/37 (fails to route audio if a 2-EV5 packet type is negiotiated). With this patch userspace can maintain a list of compatible packet types to workaround remote devices such as these. Based on a patch by Marcel Holtmann. Rebased to 2.6.39.
