| * ARM: kprobes: Tidy-up kprobes-decode.cJon Medhurst2011-04-281-108/+23
| | | | | | | | | | | | | | | | | | | | | | | | - Remove coding standard violations reported by checkpatch.pl - Delete comment about handling of conditional branches which is no longer true. - Delete comment at end of file which lists all ARM instructions. This duplicates data available in the ARM ARM and seems like an unnecessary maintenance burden to keep this up to date and accurate.

| * ARM: kprobes: Add emulation of hint instructions like NOP and WFIJon Medhurst2011-04-281-0/+24
| | | | | | | | | | | | | | | | Being able to probe NOP instructions is useful for hard-coding probeable locations and is used by the kprobes test code. Signed-off-by: Jon Medhurst <tixy@yxit.co.uk> Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>

| * ARM: kprobes: Add emulation of MOVW and MOVT instructionsJon Medhurst2011-04-281-2/+28
| | | | | | | | | | | | | | | | | | The MOVW and MOVT instructions account for approximately 7% of all instructions in a ARMv7 kernel as GCC uses them instead of a literal pool. Signed-off-by: Jon Medhurst <tixy@yxit.co.uk> Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>
| * ARM: kprobes: Reject probing of undefined data processing instructionsJon Medhurst2011-04-281-14/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The instruction decoding in space_cccc_000x needs to reject probing of instructions with undefined patterns as they may in future become defined and then emulated faultily - as has already happened with the SMC instruction. This fix is achieved by testing for the instruction patterns we want to probe and making the the default fall-through paths reject probes. This also allows us to remove some explicit tests for instructions that we wish to reject, as that is now the default action.

| * ARM: kprobes: Remove redundant code in space_1111Jon Medhurst2011-04-281-9/+5
| | | | | | | | | | | | | | | | The tests to explicitly reject probing CPS, RFE and SRS instructions are redundant as the default case is now to reject undecoded patterns. Signed-off-by: Jon Medhurst <tixy@yxit.co.uk> Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>
| * ARM: kprobes: Fix emulation of PLD instructionsJon Medhurst2011-04-281-13/+8
| | | | | | | | | | | | | | | | | | | | | | | | The PLD instructions wasn't being decoded correctly and the emulation code wasn't adjusting PC correctly. As the PLD instruction is only a performance hint we emulate it as a simple nop, and we can broaden the instruction decoding to take into account newer PLI and PLDW instructions.

| * ARM: kprobes: Reject probing of SETEND instructionsJon Medhurst2011-04-281-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The emulation of SETEND was broken as it changed the endianess for the running kprobes handling code. Rather than adding a new simulation routine to fix this we'll just reject probing of SETEND as these should be very rare in the kernel. Note, the function emulate_none is now unused but it is left in the source code as future patches will use it.

| * ARM: kprobes: Reject probing of all coprocessor instructionsJon Medhurst2011-04-281-102/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel doesn't currently support VFP or Neon code, and probing of code with CP15 operations is fraught with bad consequences. Therefore we don't need the ability to probe coprocessor instructions and the code to support this can be removed. The removed code also had at least two bugs: - MRC into R15 should set CPSR not trash PC - LDC and STC which use PC as base register needed the address offset by 8 Signed-off-by: Jon Medhurst <tixy@yxit.co.uk> Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>
| * ARM: kprobes: Fix emulation of USAD8 instructionsJon Medhurst2011-04-281-6/+4
| | | | | | | | | | | | | | | | | | | | The USAD8 instruction wasn't being explicitly decoded leading to the incorrect emulation routine being called. It can be correctly decoded in the same way as the signed multiply instructions so we move the decoding there.

| | | | | | | | | | | | | | | | | | | | | | | | instructions These sign extension instructions are encoded as extend-and-add instructions where the register to add is specified as r15.

| | | | | | | | | | | | | | | | | | The instructions space for media instructions contains some undefined patterns. We need to reject probing of these because they may in future become defined and the kprobes code may then emulate them faultily.

| * ARM: kprobes: Fix emulation of LDRD and STRD instructionsJon Medhurst2011-04-281-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The decoding of these instructions got the register indexed and immediate indexed forms the wrong way around, causing incorrect emulation. Instructions like "LDRD Rx, [Rx]" were corrupting Rx because the base register writeback was being performed unconditionally, overwriting the value just loaded from memory. The fix is to only writeback the base register when that form of the instruction is used. Note, now that we reject probing writeback with PC the emulation code doesn't need the check rn!=15.

| | | | | | | | | | | | | | | | | | | | | | unpredictably Using PC as an base register with writeback is UNPREDICTABLE, as is non word-sized loads or stores of PC. (We only really care about preventing loads to PC but it keeps the code simpler if we also exclude stores.)

| * ARM: kprobes: Reject probing of STREX and LDREX instructionsJon Medhurst2011-04-281-5/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | The emulation code for STREX and LDREX instructions is faulty, however, rather than attempting to fix this we reject probes of these instructions. We do this because they can never succeed in gaining exclusive access as the exception framework clears the exclusivity monitor when a probes breakpoint is hit. (This is a general problem when probing all instructions executing between a LDREX and its corresponding STREX and can lead to infinite retry loops.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The instructions space for 'Multiply and multiply-accumulate' instructions contains some undefined patterns. We need to reject probing of these because they may in future become defined and the kprobes code may then emulate them faultily. This has already happened with the new MLS instruction which this patch also adds correct decoding for as well as tightening up other decoding tests.

| | | | | | | | | | | | | | | | | | | | | | The MRS instruction should set mode and interrupt bits in the read value so it is simpler to use a new simulation routine (simulate_mrs) rather than some modified emulation. prep_emulate_rd12 is now unused and removed.

| | | | | | | | | | | | | | | | | | | | | | | | We need to reject probing of instructions which read SPSR because we can't handle this as the value in SPSR is lost when the exception handler for the probe breakpoint first runs.

| | | | | | | | | | | | | | | | | | | | | | When a kprobe is placed onto conditionally executed ARM instructions, many of the emulation routines used to single step them produce corrupt register results. Rather than fix all of these cases we modify the framework which calls them to test the relevant condition flags and, if the test fails, skip calling the emulation code.
