The 'Child::_revert_quota_and_destroy' assumes to be called from the client's context, which is normally the case when destroying sessions. However, if a client's session outlives the client (because the asynchronous close request to the server is still pending), the session cleanup is performed in the context of the server. Here, the 'session_response' implementation wrongly called '_revert_quota_and_destroy' to the effect that the session quota was withdrawn from the server (good) but subsequently transferred back to the server (bad). The patch replaces the call of '_revert_quota_and_destroy' with only the first - correct - part of the transaction. |

This is generic part of the Genode implementation. It consists of two parts: :_Core_: is the ultimate root of the Genode application tree and provides abstractions for the lowest-level hardware resources such as RAM, ROM, CPU, and generic device access. All generic parts of Core can be found here - for system-specific implementations refer to the appropriate 'base-<system>' directory. :_Base libraries and protocols_: that are used by each Genode component to interact with other components. This is the glue that holds everything together. _Core_ may export information about the hardware platform by an ROM called 'platform_info'. Depending on the platform, e.g. ARM or x86 or riscv, and depending on the boot mode and boot loader and kernel, some nodes may not be populated. !<platform_info> ! <acpi revision="2" rsdt="0x1fe93074" xsdt="0x1fe930e8"/> ! <boot> ! <framebuffer phys="0x7300000" width="1024" height="768" bpp="32"/> ! </boot> !</platform_info> If the ACPI RSDT and XSDT physical pointer is reported by the used kernel and/or bootloader, _Core_ may provide this information by the ROM. If the graphic device is initialised and can be directly used by a framebuffer driver, _Core_ may provide the physical pointer to the framebuffer, the resolution and color depth in bits.
