2021-12-27ACPICA: Executer: Fix the REFCLASS_REFOF case in acpi_ex_opcode_1A_0T_1R()Rafael J. Wysocki1-1/+2
ACPICA commit d984f12041392fa4156b52e2f7e5c5e7bc38ad9e If Operand[0] is a reference of the ACPI_REFCLASS_REFOF class, acpi_ex_opcode_1A_0T_1R () calls acpi_ns_get_attached_object () to obtain return_desc which may require additional resolution with the help of acpi_ex_read_data_from_field (). If the latter fails, the reference counter of the original return_desc is decremented which is incorrect, because acpi_ns_get_attached_object () does not increment the reference counter of the object returned by it. This issue may lead to premature deletion of the attached object while it is still attached and a use-after-free and crash in the host OS. For example, this may happen when on evaluation of ref_of() a local region field where there is no registered handler for the given Operation Region. Fix it by making acpi_ex_opcode_1A_0T_1R () return Status right away after a acpi_ex_read_data_from_field () failure.

2016-09-10ACPICA: Namespace: Fix dynamic table loading issuesLv Zheng1-8/+10
ACPICA commit 767ee53354e0c4b7e8e7c57c6dd7bf569f0d52bb There are issues related to the namespace/interpreter locks, which causes several ACPI functionalities not specification compliant. The lock issues were detectec when we were trying to fix the functionalities (please see Link # [1] for the details). What's the lock issues? Let's first look into the namespace/interpreter lock usages inside of the object evaluation and the table loading which are the key AML interpretion code paths: Table loading: acpi_ns_load_table L(Namespace) acpi_ns_parse_table acpi_ns_one_complete_parse(LOAD_PASS1/LOAD_PASS2) acpi_ds_load1_begion_op acpi_ds_load1_end_op acpi_ds_load2_begion_op acpi_ds_load2_end_op U(Namespace) Object evaluation: acpi_ns_evaluate L(Interpreter) acpi_ps_execute_method acpi_ds_exec_begin_op acpi_ds_exec_end_op U(Interpreter) acpi_ns_load_table L(Namespace) U(Namespace) acpi_ev_initialize_region L(Namespace) U(Namespace) address_space.Setup address_space.Handler acpi_os_wait_semaphore acpi_os_acquire_mutex acpi_os_sleep L(Interpreter) U(Interpreter) L(Interpreter) acpi_ex_resolve_node_to_value U(Interpreter) acpi_ns_check_return_value Where: 1. L(Interpreter) means acquire(MTX_INTERPRETER); 2. U(Interpreter) means release(MTX_INTERPRETER); 3. L(Namespace) means acquire(MTX_NAMESPACE); 4. U(Namespace) means release(MTX_NAMESPACE); We can see that acpi_ns_exec_module_code() (which invokes acpi_ns_evaluate) is implemented in a deferred way just in order to avoid to reacquire the namespace lock. This is in fact the root cause of many other ACPICA issues: 1. We now know for sure that the module code should be executed right in place by the Windows AML interpreter. So in the current design, if the region initializations/accesses or the table loadings (where the namespace surely should be locked again) happening during the table loading period, dead lock could happen because ACPICA never unlocks the namespace during the AML interpretion. 2. ACPICA interpreter just ensures that all static namespace nodes (named objects created during the acpi_load_tables()) are created (acpi_ns_lookup()) with the correct lock held, but doesn't ensure that the named objects created by the control method are created with the same correct lock held. It requires the control methods to be executed in a serial way after "loading a table", that's why ACPICA requires method auto serialization. This patch fixes these software design issues by extending interpreter enter/exit APIs to hold both interpreter/namespace locks to ensure the lock order correctness, so that we can get these code paths: Table loading: acpi_ns_load_table E(Interpreter) acpi_ns_parse_table acpi_ns_one_complete_parse acpi_ns_execute_table X(Interpreter) acpi_ns_load_table acpi_ev_initialize_region address_space.Setup address_space.Handler acpi_os_wait_semaphore acpi_os_acquire_mutex acpi_os_sleep E(Interpreter) X(Interpreter) Object evaluation: acpi_ns_evaluate E(Interpreter) acpi_ps_execute_method X(Interpreter) acpi_ns_load_table acpi_ev_initialize_region address_space.Setup address_space.Handler acpi_os_wait_semaphore acpi_os_acquire_mutex acpi_os_sleep E(Interpreter) X(Interpreter) Where: 1. E(Interpreter) means acquire(MTX_INTERPRETER, MTX_NAMESPACE); 2. X(Interpreter) means release(MTX_NAMESPACE, MTX_INTERPRETER); After this change, we can see: 1. All namespace nodes creations are locked by the namespace lock. 2. All namespace nodes referencing are locked with the same lock. 3. But we also can notice a defact that, all namespace nodes deletions could be affected by this change. As a consequence, acpi_ns_delete_namespace_subtree() may delete a static namespace node that is still referenced by the interpreter (for example, the parser scopes). Currently, we needn't worry about the last defact because in ACPICA, table unloading is not fully functioning, its design strictly relies on the fact that when the namespace deletion happens, either the AML table or the OSPMs should have been notified and thus either the AML table or the OSPMs shouldn't reference deletion-related namespace nodes during the namespace deletion. And this change still works with the above restrictions applied. While making this a-step-forward helps us to correct the wrong grammar to pull many things back to the correct rail. And pulling things back to the correct rail in return makes it possible for us to support fully functioning table unloading after doing many cleanups. While this patch is generated, all namespace locks are examined to ensure that they can meet either of the following pattens: 1. L(Namespace) U(Namespace) 2. E(Interpreter) X(Interpreter) 3. E(Interpreter) X(Interpreter) L(Namespace) U(Namespace) E(Interpreter) X(Interpreter) We ensure this by adding X(Interpreter)/E(Interpreter) or removing U(Namespace)/L(Namespace) for those currently are executed in the following order: E(Interpreter) L(Namespace) U(Namespace) X(Interpreter) And adding E(Interpreter)/X(Interpreter) for those currently are executed in the following order: X(Interpreter) E(Interpreter) Originally, the interpreter lock is held for the execution AML opcodes, the namespace lock is held for the named object creation AML opcodes. Since they are actually same in MS interpreter (can all be executed during the table loading), we can combine the 2 locks and tune the locking code better in this way. Lv Zheng.

The problem is that DerefOf did not resolve these objects to actual values. An "Integer" object is simple, return the value. But a field in an operation region will require a read operation. For a BufferField, the appropriate data must be extracted from the parent buffer. NOTE: It appears that this issues is present in Windows7 but not Windows8.

2013-01-10ACPICA: Cleanup indentation to reduce differences between Linux and ACPICA.Lv Zheng1-7/+1
This is a cosmetic patch only. Comparison of the resulting binary showed only line number differences. This patch does not affect the generation of the Linux binary. This patch decreases 210 lines of 20121018 divergence.diff. The ACPICA source codes uses a totally different indentation style from the Linux to be compatible with other users (operating systems or BIOS). Indentation differences are critical to the release automation. There are two causes related to the "indentation" that are affecting the release automation: 1. The ACPICA -> Linux release process is: ACPICA source -- acpisrc - hierarchy - indent -> linuxized ACPICA source -- diff -> linuxized ACPICA patch (x) -- human intervention -> linuxized ACPICA patch (o) Where 'x' means "cannot be directly applied to the Linux" 'o' means "can be directly applied to the Linux" Different "indent" version or "indent" options used in the "indent" step will lead to different divergences. The version of "indent" used for the current release process is: GNU indent 2.2.11 The options of "indent" used for the current release process is: -npro -kr -i8 -ts8 -sob -l80 -ss -ncs 2. Manual indentation prettifying work in the Linux side will also harm the automatically generated linuxized ACPICA patches, making them impossible to apply directly. This patch fixes source code differences caused by the two causes so that the "human intervention" can be reduced in the future. Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.
