From 35ed01ba5448208695ada5fa20a13c0a4689a1c1 Mon Sep 17 00:00:00 2001 From: Fabiano Rosas Date: Tue, 26 Sep 2023 16:25:02 -0300 Subject: [PATCH 01/24] optionrom: Remove build-id section Our linker script for optionroms specifies only the placement of the .text section, leaving the linker free to place the remaining sections at arbitrary places in the file. Since at least binutils 2.39, the .note.gnu.build-id section is now being placed at the start of the file, which causes label addresses to be shifted. For linuxboot_dma.bin that means that the PnP header (among others) will not be found when determining the type of ROM at optionrom_setup(): (0x1c is the label _pnph, where the magic "PnP" is) $ xxd /usr/share/qemu/linuxboot_dma.bin | grep "PnP" 00000010: 0000 0000 0000 0000 0000 1c00 2450 6e50 ............$PnP $ xxd pc-bios/optionrom/linuxboot_dma.bin | grep "PnP" 00000010: 0000 0000 0000 0000 0000 4c00 2450 6e50 ............$PnP ^bad Using a freshly built linuxboot_dma.bin ROM results in a broken boot: SeaBIOS (version rel-1.16.2-0-gea1b7a073390-prebuilt.qemu.org) Booting from Hard Disk... Boot failed: could not read the boot disk Booting from Floppy... Boot failed: could not read the boot disk No bootable device. We're not using the build-id section, so pass the --build-id=none option to the linker to remove it entirely. Note: In theory, this same issue could happen with any other section. The ideal solution would be to have all unused sections discarded in the linker script. However that would be a larger change, specially for the pvh rom which uses the .bss and COMMON sections so I'm addressing only the immediate issue here.

When this occurs the unsigned async_len variable underflows and becomes a large offset which writes past the end of the allocated SCSI buffer. Restrict the non-DMA transfer length to be the smallest of the expected transfer length and the available FIFO data to ensure that it is no longer possible for the SCSI buffer overflow to occur.

However, there is still a need for simple configuration of the audio backend in the desktop case; therefore, if no audiodev is passed to audio_init(), go through a bunch of simple Audiodev* structures and pick the first that can be initialized successfully. The only QEMU_AUDIO_* option that is left in, waiting for a better idea, is QEMU_AUDIO_DRV=none which is used by qtest. Remove all the parsing code, including the concept of "can_be_default" audio drivers: now that audio_prio_list[] is only used in a single place, wav can be excluded directly in that function.
