2023-10-19hw/audio/pcspk: Inline pcspk_init()Philippe Mathieu-Daudé4-13/+11
pcspk_init() is a legacy init function, inline and remove it. Since the device is realized using &error_fatal, use the same error for setting the "pit" link.

We can however use the 'ArchCPU *' type in the public header. By keeping the TYPE_MIPS_CPU QOM type check in the link property declaration, QOM core code will still check the property is a correct MIPS CPU.

2023-10-19cutils: Fix get_relocated_path on WindowsAkihiko Odaki1-7/+11
get_relocated_path() did not have error handling for PathCchSkipRoot() because a path given to get_relocated_path() was expected to be a valid path containing a drive letter or UNC server/share path elements on Windows, but sometimes it turned out otherwise. The paths passed to get_relocated_path() are defined by macros generated by Meson. Meson in turn uses a prefix given by the configure script to generate them. For Windows, the script passes /qemu as a prefix to Meson by default. As documented in docs/about/build-platforms.rst, typically MSYS2 is used for the build system, but it is also possible to use Linux as well. When MSYS2 is used, its Bash variant recognizes /qemu as a MSYS2 path, and converts it to a Windows path, adding the MSYS2 prefix including a drive letter or UNC server/share path elements. Such a conversion does not happen on a shell on Linux however, and /qemu will be passed as is in the case. Implement a proper error handling of PathCchSkipRoot() in get_relocated_path() so that it can handle a path without a drive letter or UNC server/share path elements.

2023-10-18linux-user: Remap guest SIGABRTRichard Henderson1-7/+35
Distinguish host SIGABRT from guest SIGABRT by mapping the guest signal onto one of the host RT signals. This prevents a cycle by which a host assertion failure is caught and handled by host_signal_handler, queued for the guest, and then we attempt to continue past the host abort. What happens next depends on the host libc, but is neither good nor helpful. Acked-by: Helge Deller <deller@gmx.de> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2023-10-18linux-user: Only register handlers for core_dump_signal by defaultRichard Henderson1-29/+14
The set of fatal signals is really immaterial. If one arrives, and is unhandled, then the qemu process dies and the parent gets the correct signal. It is only for those signals which we would like to perform a guest core dump instead of a host core dump that we need to catch.

2023-10-18linux-user: Detect and report host crashesHelge Deller1-6/+63
If there is an internal program error in the qemu source code which raises SIGSEGV or SIGBUS, we currently assume the signal belongs to the guest. With an artificial error introduced, we will now print QEMU internal SIGSEGV {code=MAPERR, addr=(nil)} Signed-off-by: Helge Deller <deller@gmx.de> Message-Id: <20230812164314.352131-1-deller@gmx.de> [rth: Use in_code_gen_buffer and die_with_signal; drop backtrace] Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-10-18linux-user: Exit not abort in die_with_backtraceRichard Henderson1-1/+1
This line is supposed to be unreachable, but if we're going to have it at all, SIGABRT via abort() is subject to the same signal peril that created this function in the first place.

2023-10-18linux-user/sh4: Fix crashes on signal deliveryMikulas Patocka1-0/+8
sh4 uses gUSA (general UserSpace Atomicity) to provide atomicity on CPUs that don't have atomic instructions. A gUSA region that adds 1 to an atomic variable stored in @R2 looks like this: 4004b6: 03 c7 mova 4004c4 <gusa+0x10>,r0 4004b8: f3 61 mov r15,r1 4004ba: 09 00 nop 4004bc: fa ef mov #-6,r15 4004be: 22 63 mov.l @r2,r3 4004c0: 01 73 add #1,r3 4004c2: 32 22 mov.l r3,@r2 4004c4: 13 6f mov r1,r15 R0 contains a pointer to the end of the gUSA region R1 contains the saved stack pointer R15 contains negative length of the gUSA region When this region is interrupted by a signal, the kernel detects if R15 >= -128U. If yes, the kernel rolls back PC to the beginning of the region and restores SP by copying R1 to R15. The problem happens if we are interrupted by a signal at address 4004c4. R15 still holds the value -6, but the atomic value was already written by an instruction at address 4004c2. In this situation we can't undo the gUSA. The function unwind_gusa does nothing, the signal handler attempts to push a signal frame to the address -6 and crashes. This patch fixes it, so that if we are interrupted at the last instruction in a gUSA region, we copy R1 to R15 to restore the correct stack pointer and avoid crashing. There's another bug: if we are interrupted in a delay slot, we save the address of the instruction in the delay slot. We must save the address of the previous instruction.

QEMU mips userspace emulation crashes with "qemu: unhandled CPU exception 0x15 - aborting" when one of the integer arithmetic instructions detects an overflow.

2023-10-18linux-user: Fixes for zero_bssRichard Henderson1-13/+40
The previous change, 2d385be6152, assumed !PAGE_VALID meant that the page would be unmapped by the elf image. However, since we reserved the entire image space via mmap, PAGE_VALID will always be set. Instead, assume PROT_NONE for the same condition. Furthermore, assume bss is only ever present for writable segments, and that there is no page overlap between PT_LOAD segments. Instead of an assert, return false to indicate failure.
