2022-10-01x86: re-initialize RNG seed when selecting kernelJason A. Donenfeld
We don't want it to be possible to re-read the RNG seed after ingesting it, because this ruins forward secrecy. Currently, however, the setup data section can just be re-read. Since the kernel is always read after the setup data, use the selection of the kernel as a trigger to re-initialize the RNG seed, just like we do on reboot, to preserve forward secrecy.

2022-10-01configure, meson: move C++ compiler detection to meson.buildPaolo Bonzini
The test is slightly weaker than before, because it does not call an extern "C" function from a C source file. However, in practice what we seek to detect is ABI compatibility of the various sanitizer flags, and for that it is enough to compile anything with CC and link it with CXX.

2022-10-01meson: require 0.61.3Paolo Bonzini
This removes the dependency of dbus-display on --enable-modules. It also allows cleanups in modinfo collection and allows moving C++ compiler detection to meson.build. Because it is now deprecated to use install_subdir to create an empty directory, replace it with install_emptydir. Updating the Meson submodule to 0.61.5 also removes the message WARNING: Broken python installation detected. Python files installed by Meson might not be found by python interpreter. unless using system meson is forced with --meson.

2022-10-01meson: -display dbus and CFI are incompatiblePaolo Bonzini
The generated skeletons for DBus call the finalize method of the parent type using code like G_OBJECT_CLASS (qemu_dbus_display1_chardev_skeleton_parent_class)->finalize (object); However, the finalize method is defined in a shared library that is not compiled with CFI.

2022-09-29ui: fix path to dbus-display1.hPaolo Bonzini
While the source directory is always included in the include path, the corresponding directory in the build tree is not. Therefore, custom_targets (e.g. ui/dbus-display1.h) must be referred to using the full path. This avoids a build failure when ui/dbus-chardev.c is not built as a module: In file included from ../ui/dbus-chardev.c:32: ../ui/dbus.h:34:10: fatal error: dbus-display1.h: No such file or directory 34 | #include "dbus-display1.h" | ^~~~~~~~~~~~~~~~~ Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2022-09-27x86: return modified setup_data only if read as memory, not as fileJason A. Donenfeld
If setup_data is being read into a specific memory location, then generally the setup_data address parameter is read first, so that the caller knows where to read it into. In that case, we should return setup_data containing the absolute addresses that are hard coded and determined a priori. This is the case when kernels are loaded by BIOS, for example. In contrast, when setup_data is read as a file, then we shouldn't modify setup_data, since the absolute address will be wrong by definition. This is the case when OVMF loads the image. This allows setup_data to be used like normal, without crashing when EFI tries to use it. (As a small development note, strangely, fw_cfg_add_file_callback() was exported but fw_cfg_add_bytes_callback() wasn't, so this makes that consistent.)

2022-09-22configure: Avoid use of 'local' as it is non-POSIXPeter Maydell
We use the non-POSIX 'local' keyword in just two places in configure; rewrite to avoid it. In do_compiler(), just drop the 'local' keyword. The variable 'compiler' is only used elsewhere in the do_compiler_werror() function, which already uses the variable as a normal non-local one. In probe_target_compiler(), $try and $t are both local; make them normal variables and use a more obviously distinct variable name for $t.

The combined_key[... QIO_CHANNEL_WEBSOCK_GUID_LEN ...] array in qio_channel_websock_handshake_send_res_ok() expands to a call to strlen(QIO_CHANNEL_WEBSOCK_GUID), and the compiler doesn't realize the string is const, so consider combined_key[] being a variable-length array. To remove the variable-length array, we provide it a hint to the compiler by using sizeof() - 1 instead of strlen(). Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Reviewed-by: Daniel P.

2022-09-22chardev/baum: Use definitions to avoid dynamic stack allocationPhilippe Mathieu-Daudé
We know 'x * y' will be at most 'X_MAX * Y_MAX' (which is not a big value, it is actually 84). Instead of having the compiler use variable-length array, declare an array able to hold the maximum 'x * y'.

2022-09-22hw/net/lan9118: Signal TSFL_INT flag when TX FIFO reaches specified levelLucas Dietrich
The LAN9118 allows the guest to specify a level for both the TX and RX FIFOs at which an interrupt will be generated. We implement the RSFL_INT interrupt for the RX FIFO but are missing the handling of the equivalent TSFL_INT for the TX FIFO. Add the missing test to set the interrupt if the TX FIFO has exceeded the guest-specified level. This flag is required for Micrium lan911x ethernet driver to work.
