2025-03-14linux-user/arm: Remove unused get_put_user macrosPeter Maydell1-39/+4
In linux-user/arm/cpu_loop.c we define a full set of get/put macros for both code and data (since the endianness handling is different between the two). However the only one we actually use is get_user_code_u32(). Remove the rest. We leave a comment noting how data-side accesses should be handled for big-endian, because that's a subtle point and we just removed the macros that were effectively documenting it.

2025-03-10plugins/api: split out binary path/start/end/entry codeAlex Bennée2-0/+16
To move the main api.c to a single build compilation object we need to start splitting out user and system specific code. As we need to grob around host headers we move these particular helpers into the *-user mode directories. The binary/start/end/entry helpers are all NOPs for system mode. While using the plugin-api.c.inc trick means we build for both linux-user and bsd-user the BSD user-mode command line is still missing -plugin. This can be enabled once we have reliable check-tcg tests working for the BSDs.

SA_RESTORER and the associated sa_restorer field of struct sigaction are an obsolete feature, not expected to be used by future architectures. They are also absent on RISC-V, LoongArch, Hexagon and OpenRISC, but defined due to their use of generic/signal.h. This leads to corrupted data and out-of-bounds accesses. Move the definition of TARGET_SA_RESTORER out of generic/signal.h into the target_signal.h files that need it.

2025-02-10gdbstub: Allow late attachmentIlya Leoshkevich1-1/+0
Allow debugging individual processes in multi-process applications by starting them with export QEMU_GDB=/tmp/qemu-%d.sock,suspend=n. Currently one would have to attach to every process to ensure the app makes progress. In case suspend=n is not specified, the flow remains unchanged. If it is specified, then accepting the client connection is delegated to a thread. In the future this machinery may be reused for handling reconnections and interruptions. On accepting a connection, the thread schedules gdb_handlesig() on the first CPU and wakes it up with host_interrupt_signal. Note that the result of this gdb_handlesig() invocation is handled, as opposed to many other existing call sites. These other call sites probably need to be fixed separately.

2025-02-10user: Introduce host_interrupt_signalIlya Leoshkevich1-5/+20
Attaching to the gdbstub of a running process requires stopping its threads. For threads that run on a CPU, cpu_exit() is enough, but the only way to grab attention of a thread that is stuck in a long-running syscall is to interrupt it with a signal. Reserve a host realtime signal for this, just like it's already done for TARGET_SIGABRT on Linux. This may reduce the number of available guest realtime signals by one, but this is acceptable, since there are quite a lot of them, and it's unlikely that there are apps that need them all. Set signal_pending for the safe_sycall machinery to prevent invoking the syscall. This is a lie, since we don't queue a guest signal, but process_pending_signals() can handle the absence of pending signals. The syscall returns with QEMU_ERESTARTSYS errno, which arranges for the automatic restart. This is important, because it helps avoiding disturbing poorly written guests.

2025-01-17system: propagate Error to gdbserver_start (and other device setups)Alex Bennée1-5/+1
This started as a clean-up to properly pass a Error handler to the gdbserver_start so we could do the right thing for command line and HMP invocations. Now that we have cleaned up foreach_device_config_or_exit() in earlier patches we can further simplify by it by passing &error_fatal instead of checking the return value. Having a return value is still useful for HMP though so tweak the return to use a simple bool instead.
