2025-06-23linux-user: fix resource leaks in gen-vdsoDaniel P. Berrangé1-11/+16
There are a number of resource leaks in gen-vdso. In theory they are harmless because this is a short lived process, but when building QEMU with --extra-cflags="-fsanitize=address" problems ensure. The gen-vdso program is run as part of the build, and that aborts due to the sanitizer identifying memory leaks, leaving QEMU unbuildable. FAILED: libqemu-x86_64-linux-user.a.p/vdso.c.inc /var/home/berrange/src/virt/qemu/build/linux-user/gen-vdso -o libqemu-x86_64-linux-user.a.p/vdso.c.inc ../linux-user/x86_64/vdso.so ================================================================= ==1696332==ERROR: LeakSanitizer: detected memory leaks Direct leak of 2968 byte(s) in 1 object(s) allocated from: #0 0x56495873f1f3 (/var/home/berrange/src/virt/qemu/build/linux-user/gen-vdso+0xa11f3) (BuildId: b69e241ad44719b6f3934f3c71dfc6727e8bdb12) #1 0x564958780b90 (/var/home/berrange/src/virt/qemu/build/linux-user/gen-vdso+0xe2b90) (BuildId: b69e241ad44719b6f3934f3c71dfc6727e8bdb12) This complaint is about the 'buf' variable, however, the FILE objects are also leaked in some error scenarios, so this fix refactors the cleanup paths to fix all leaks.

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.

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.

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.
