2011-06-14ARM: etm: Support multiple ETMs/PTMs.Arve Hjønnevåg
If more than one ETM or PTM are present, configure all of them and enable the formatter in the ETB. This allows tracing on dual core systems (e.g. omap4). Change-Id: I028657d5cf2bee1b23f193d4387b607953b35888 Signed-off-by: Arve Hjønnevåg <arve@android.com>
2011-06-14ARM: etm: Return the entire trace buffer if it is empty after resetArve Hjønnevåg
On some SOCs the read and write pointer are reset when the chip resets, but the trace buffer content is preserved. If the status bits indicates that the buffer is empty and we have never started tracing, assume the buffer is full instead. This can be useful if the system rebooted from a watchdog reset.

2011-06-14ARM: etm: Add some missing locks and error checksArve Hjønnevåg
It is not safe to call etm_lock or etb_lock without holding the mutex since another thread may also have unlocked the registers. Also add some missing checks for valid etb_regs in the etm sysfs entries. Change-Id: I939f76a6ea7546a8fc0d4ddafa2fd2b6f38103bb Signed-off-by: Arve Hjønnevåg <arve@android.com>
2011-06-14ARM: etm: Configure data tracingArve Hjønnevåg
The old code enabled data tracing, but did not configure the range. We now configure it to trace all data addresses by default, and add a trace_data_range attribute to change the range or disable data tracing.

2011-06-14ARM: etm: Allow range selectionArve Hjønnevåg
Trace kernel text segment by default as before, allow tracing of other ranges by writing a range to /sys/devices/etm/trace_range, or to trace everything by writing 0 0. Change-Id: Ibb734ca820fedf79560b20536247f1e1700cdc71 Signed-off-by: Arve Hjønnevåg <arve@android.com>
2011-06-14ARM: etm: Don't try to clear the buffer full status after reading the bufferArve Hjønnevåg
If the write address was at the end of the buffer, toggling the trace capture bit would set the RAM-full status instead of clearing it, and if any of the stop bits in the formatter is set toggling the trace capture bit may not do anything. Instead use the read position to find out if the data has already been returned. This also fixes the read function so it works when the trace buffer is larger than the buffer passed in from user space. The old version would reset the trace buffer pointers after every read, so the second call to read would always return 0.

2011-06-14ARM: etm: Don't limit tracing to only non-secure code.Arve Hjønnevåg
On some systems kernel code is considered secure, and this code already limits tracing to the kernel text segment which results in no trace data. Change-Id: I098a0753e874859446d098e1ee209f67fc13cd5d Signed-off-by: Arve Hjønnevåg <arve@android.com>

2011-06-14Bluetooth: 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.

2011-06-14net: Reorder incoming packets in PPPoLAC and PPPoPNS.Chia-chi Yeh
PPP handles packet loss but does not work with out of order packets. This change performs reordering of incoming data packets within a sliding window of one second. Since sequence number is optional, receiving a packet without it will drop all queued packets. Currently the logic is triggered by incoming packets, so queued packets have to wait till another packet is arrived. It is done for simplicity since no additional locks or threads are required. For reliable protocols, a retransmission will kick it. For unreliable protocols, queued packets just seem like packet loss. Time-critical protocols might be broken, but they never work with queueing anyway. Signed-off-by: Chia-chi Yeh <chiachi@android.com>
2011-06-14net: Support nuking IPv6 sockets as well as IPv4.Lorenzo Colitti
On Linux, when an interface goes down all its IPv6 addresses are deleted, so relying on knowing the previous IPv6 addresses on the interface is brittle. Instead, support nuking all sockets that are bound to IP addresses that are not configured and up on the system. This behaviour is triggered by specifying the unspecified address (:: or 0.0.0.0). If an IP address is specified, the behaviour is unchanged, except the ioctl now supports IPv6 as well as IPv4. Signed-off-by: Lorenzo Colitti <lorenzo@google.com>

2011-06-14USB: gadget: f_mtp: Don't block in mtp_send_eventMike Lockwood
We used to wait for the previous interrupt packet to complete before sending the next packet. But unfortunately the previous packet will not complete until USB is disconnected if the host is not listening on the interrupt endpoint (which is the case with libmtp on Linux and Mac). To avoid hanging indefinitely in this case, we now simply return -EBUSY if the previous interrupt packet has not completed yet. Signed-off-by: Mike Lockwood <lockwood@android.com>

If the PC on the stack is updated in entry-armv.S, do_undefinstr can get called after the fixup. do_undefinstr does its own fixup, and doing both causes the PC to point to half way through an instruction.

The exception handler in entry-armv.S checks for thumb mode and correctly determines the exception location and instruction, but VFP_bounce uses the uncorrected location off the stack. If the VFP exception occured in Thumb mode, fix up the exception location on the stack to match the value that would be returned in ARM mode. Fixes segfaults in userspace applications running in Thumb mode caused by a handled VFP exception returning to the middle of the instruction that triggered the exception.
