* ACPICA: delete utcache.cLen Brown2009-01-082-316/+1

* ACPICA: Restructure includes into public/privateBob Moore2008-12-3115-58/+71
| | | | | | | | | | | | acpi.h now includes only the "public" acpica headers. All other acpica headers are "private" and should not be included by acpica users. One new file, accommon.h is used to include the commonly used private headers for acpica code generation. Future plans are to move all private headers to a new subdirectory.

* ACPICA: New: acpi_get_gpe_device interfaceBob Moore2008-12-311-2/+4
| | | | | | | | | | | | | This function maps an input GPE index to a GPE block device. Also Added acpi_current_gpe_count to track the current number of GPEs that are being managed by the ACPICA core (both FADT-based GPEs and the GPEs contained in GPE block devices.) Modify drivers/acpi/system.c to use these 2 new interfaces Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPICA: Add support to externally execute _OSI methodBob Moore2008-12-291-3/+3
| | | | | | | | | | | | The current implemenation of _OSI within ACPICA only allows other control methods to execute _OSI. This change allows the host OS to execute _OSI via the AcpiEvaluateObject interface. _OSI is a special method -- it does not exist in the AML code, it is implemented within ACPICA.

* ACPI: fix 2.6.28 acpi.debug_level regressionBjorn Helgaas2008-12-191-1/+1
| | | | | | | | | | | | | | | acpi_early_init() was changed to over-write the cmdline param, making it really inconvenient to set debug flags at boot-time. Also, This sets the default level to "info", which is what all the ACPI drivers use. So to enable messages from drivers, you only have to supply the "layer" (a.k.a. "component"). For non-"info" ACPI core and ACPI interpreter messages, you have to supply both level and layer masks, as before.

| | | | | | | | | | | | | | | Fixed two possible memory leaks in the error exit paths of acpi_ut_update_objerct_reference() and acpi_ut_walk_package_tree() These functions are similar in that they use a stack of state objects in order to eliminate recursion.

I.e. the new CONFIG_ACPI_PCI_SLOT=y option was causing this crash. But the bug is not mainly in this new PCI code - that code was just hitting the ACPI code in a new way which made ACPI break. The crash signature shows that we are crashing on this instruction: movb $0x0, (%ecx, %ebx, 1) ECX and EBX are 0x10 and -1. It's this line in drivers/acpi/namespace/nsnames.c's acpi_ns_build_external_path(): name_buffer[index] = 0; I.e. name_buffer is 0x10 and index is -1. index -1 corresponds to size 0, and name_buffer 0x10 is slab's ZERO_SIZE_PTR special-case for zero-sized allocations. I.e. when we called acpi_ns_handle_to_pathname(), we got required_size of 0 due to an error condition, but this is passed to the ACPI allocator unconditionally: required_size = acpi_ns_get_pathname_length(node); /* Validate/Allocate/Clear caller buffer */ status = acpi_ut_initialize_buffer(buffer, required_size); if (ACPI_FAILURE(status)) { return_ACPI_STATUS(status); } Where acpi_ut_initialize_buffer(), through many (unnecessary) layers, ends up calling kzalloc(0). Which returns 0x10 and that then causes the crash later on. So fix both callers of acpi_ns_get_pathname_length(), which can return 0 in case of an invalid node. Also add a WARN_ON() against zero sized allocations in acpi_ut_initialize_buffer() to make it easier to find similar instances of this bug. I have tested this patch for the past 24 hours and the crash has not reappeared. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andi Kleen <ak@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed problem where NULL package elements were not returned to the AcpiEvaluateObject interface correctly. Instead of returning a NULL ACPI_OBJECT package element, the element was simply ignored, potentially causing a buffer overflow and/or confusing the caller who expected a fixed number of elements. http://bugzilla.kernel.org/show_bug.cgi?id=10132 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>
