* pm/sleep: Add PM_USERSPACE_AUTOSLEEP KconfigKalesh Singh2022-07-013-3/+24
| | | | | | | | | | | | | | | | | | | | | Systems that initiate frequent suspend/resume from userspace can make the kernel aware by enabling PM_USERSPACE_AUTOSLEEP config. This allows for certain sleep-sensitive code (wireguard/rng) to decide on what preparatory work should be performed (or not) in their pm_notification callbacks. This patch was prompted by the discussion at [1] which attempts to remove CONFIG_ANDROID that currently guards these code paths.

* uacce: Handle parent device removal or parent driver module rmmodJean-Philippe Brucker2022-07-012-48/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | The uacce driver must deal with a possible removal of the parent device or parent driver module rmmod at any time. Although uacce_remove(), called on device removal and on driver unbind, prevents future use of the uacce fops by removing the cdev, fops that were called before that point may still be running. Serialize uacce_fops_open() and uacce_remove() with uacce->mutex. Serialize other fops against uacce_remove() with q->mutex. Since we need to protect uacce_fops_poll() which gets called on the fast path, replace uacce->queues_lock with q->mutex to improve scalability. The other fops are only used during setup. uacce_queue_is_valid(), checked under q->mutex or uacce->mutex, denotes whether uacce_remove() has disabled all queues. If that is the case, don't go any further since the parent device is being removed and uacce->ops should not be called anymore.

* scripts/tags.sh: Include tools directory in tags generationVipin Sharma2022-07-011-8/+1
| | | | | | | | | | | | | | | | Add tools directory in generating tags and quiet the "No such file or directory" warnings. It reverts the changes introduced in commit 162343a876f1 ("scripts/tags.sh: exclude tools directory from tags generation") while maintainig the original intent of the patch to get rid of the warnings. This allows the root level cscope files to include tools source code besides kernel and a single place to browse the code for both.

* Binder: add TF_UPDATE_TXN to replace outdated txnLi Li2022-06-273-3/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the target process is busy, incoming oneway transactions are queued in the async_todo list. If the clients continue sending extra oneway transactions while the target process is frozen, this queue can become too large to accommodate new transactions. That's why binder driver introduced ONEWAY_SPAM_DETECTION to detect this situation. It's helpful to debug the async binder buffer exhausting issue, but the issue itself isn't solved directly. In real cases applications are designed to send oneway transactions repeatedly, delivering updated inforamtion to the target process. Typical examples are Wi-Fi signal strength and some real time sensor data. Even if the apps might only care about the lastet information, all outdated oneway transactions are still accumulated there until the frozen process is thawed later. For this kind of situations, there's no existing method to skip those outdated transactions and deliver the latest one only. This patch introduces a new transaction flag TF_UPDATE_TXN. To use it, use apps can set this new flag along with TF_ONE_WAY. When such an oneway transaction is to be queued into the async_todo list of a frozen process, binder driver will check if any previous pending transactions can be superseded by comparing their code, flags and target node. If such an outdated pending transaction is found, the latest transaction will supersede that outdated one. This effectively prevents the async binder buffer running out and saves unnecessary binder read workloads.

They have been added with a status disabled in order to keep our legacy unchanged. It is actually not enough to keep our legacy unchanged. First, just a reminder about our use case: TF-A (BL2) loads and starts OP-TEE, then loads and runs U-Boot. U-Boot code checks if an OP-TEE is running, if yes it searches in Kernel device tree if an OP-TEE node is present: -If the OP-TEE node is not present then U-Boot copies OP-TEE node and its reserved memory region from U-Boot device tree to the kernel device tree. -If the OP-TEE node is present then it does nothing (this OP-TEE node will be used by Linux). So U-Boot lets the kernel device tree unchanged thinking it is correct for an OP-TEE usage. It is the case for our legacy boards, the OP-TEE node is present (although disabled) but the reserved memory region is not declared. As no memory region has been reserved for OP-TEE, the end of DDR is seen by the kernel as free and then used for CMA. But as OP-TEE is running, this end of DDR is already used by OP-TEE. So as soon as kernel tries to access to the CMA region OP-TEE raises an error. To fix it, all OP-TEE node and SCMI is moved in a dedicated file.

Issues reported on RK3568 EVB1 and BPI-R2 pro platforms using SCMI. More checks were added to validate the firmware response but that resulted in breaking above platforms, so the checks are relaxed when for cases where there is no potential memory corruption issues. 2. Possible data leak by reading more than required length from the firmware. Recent addition of support for v3.1 extended names used larger buffers in the kernel and used their size to read response from the firmware even for cases where shorter formats are used. While that is mostly harmless except when firmware sends malformed non-NULL terminated buffers. 3. Possible issues sending unsupported commands to the firmware. SENSOR_AXIS_NAME_GET added in v3.1 needs to be used only if the firmware supports it. While the firmware conformant to the spec must return not supported error for any unsupported features, it is always safer to avoid issuing commands that are known to be unsupported. 4. Incorrect error propagation in scmi_voltage_descriptors_get. Since the return value is not reset for each iteration of the loop, the error value in the previous iteration will be carried for the current one. Fix that by not saving the return values into local variable. 5. Some warnings reported by cppcheck * tag 'scmi-fixes-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Fix incorrect error propagation in scmi_voltage_descriptors_get firmware: arm_scmi: Avoid using extended string-buffers sizes if not necessary firmware: arm_scmi: Fix SENSOR_AXIS_NAME_GET behaviour when unsupported firmware: arm_scmi: Remove all the unused local variables firmware: arm_scmi: Relax base protocol sanity checks on the protocol list Link: https://lore.kernel.org/r/20220614100007.1029881-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

While that should be fine if the firmware terminates the string before 16 bytes, there is possibility of copying random data if the name is not NULL terminated by the firmware. SCMI base protocol agent_name/vendor_id/sub_vendor_id are defined by the specification as NULL-terminated ASCII strings up to 16-bytes in length. The underlying buffers and message descriptors are currently bigger than needed; resize them to fit only the strictly needed 16 bytes to avoid any possible leaks when reading data from the firmware. Change the size argument of strlcpy to use SCMI_SHORT_NAME_MAX_SIZE always when dealing with short domain names, so as to limit the possibility that an ill-formed non-NULL terminated short reply from the SCMI platform firmware can leak stale content laying in the underlying transport shared memory area. While at that, convert all strings handling routines to use the preferred strscpy.
