2023-02-03hw/char/pl011: refactor FIFO depth handling codeEvgeny Iakovlev2-13/+22
PL011 can be in either of 2 modes depending guest config: FIFO and single register. The last mode could be viewed as a 1-element-deep FIFO. Current code open-codes a bunch of depth-dependent logic. Refactor FIFO depth handling code to isolate calculating current FIFO depth. One functional (albeit guest-invisible) side-effect of this change is that previously we would always increment s->read_pos in UARTDR read handler even if FIFO was disabled, now we are limiting read_pos to not exceed FIFO depth (read_pos itself is reset to 0 if user disables FIFO).

2023-02-02tcg: exclude non-memory effecting helpers from instrumentationEmilio Cota3-4/+8
There are actually a whole bunch of helpers that don't affect memory that we shouldn't instrument. They are helpfully identified by the TCG_CALL_NO_SIDE_EFFECTS flag which marks out lookup_tb_ptr as well as a lot of the maths helpers. To avoid the string compare we introduce a new flag for plugin internals so we skip that too.

2023-02-02plugins: fix optimization in plugin_gen_disable_mem_helpersEmilio Cota2-8/+25
We were mistakenly checking tcg_ctx->plugin_insn as a canary to know whether the TB had emitted helpers that might have accessed memory. The problem is that tcg_ctx->plugin_insn gets updated on every instruction in the TB, which results in us wrongly performing the optimization (i.e. not clearing cpu->plugin_mem_cbs) way too often, since it's not rare that the last instruction in the TB doesn't use helpers. Fix it by tracking a per-TB canary. While at it, expand documentation.

2023-02-02cpu: free cpu->tb_jmp_cache with RCUEmilio Cota3-3/+12
Fixes the appended use-after-free. The root cause is that during tb invalidation we use CPU_FOREACH, and therefore to safely free a vCPU we must wait for an RCU grace period to elapse. $ x86_64-linux-user/qemu-x86_64 tests/tcg/x86_64-linux-user/munmap-pthread ================================================================= ==1800604==ERROR: AddressSanitizer: heap-use-after-free on address 0x62d0005f7418 at pc 0x5593da6704eb bp 0x7f4961a7ac70 sp 0x7f4961a7ac60 READ of size 8 at 0x62d0005f7418 thread T2 #0 0x5593da6704ea in tb_jmp_cache_inval_tb ../accel/tcg/tb-maint.c:244 #1 0x5593da6704ea in do_tb_phys_invalidate ../accel/tcg/tb-maint.c:290 #2 0x5593da670631 in tb_phys_invalidate__locked ../accel/tcg/tb-maint.c:306 #3 0x5593da670631 in tb_invalidate_phys_page_range__locked ../accel/tcg/tb-maint.c:542 #4 0x5593da67106d in tb_invalidate_phys_range ../accel/tcg/tb-maint.c:614 #5 0x5593da6a64d4 in target_munmap ../linux-user/mmap.c:766 #6 0x5593da6dba05 in do_syscall1 ../linux-user/syscall.c:10105 #7 0x5593da6f564c in do_syscall ../linux-user/syscall.c:13329 #8 0x5593da49e80c in cpu_loop ../linux-user/x86_64/../i386/cpu_loop.c:233 #9 0x5593da6be28c in clone_func ../linux-user/syscall.c:6633 #10 0x7f496231cb42 in start_thread nptl/pthread_create.c:442 #11 0x7f49623ae9ff (/lib/x86_64-linux-gnu/libc.so.6+0x1269ff) 0x62d0005f7418 is located 28696 bytes inside of 32768-byte region [0x62d0005f0400,0x62d0005f8400) freed by thread T148 here: #0 0x7f49627b6460 in __interceptor_free ../../../../src/libsanitizer/asan/asan_malloc_linux.cpp:52 #1 0x5593da5ac057 in cpu_exec_unrealizefn ../cpu.c:180 #2 0x5593da81f851 (/home/cota/src/qemu/build/qemu-x86_64+0x484851) Signed-off-by: Emilio Cota <cota@braap.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20230111151628.320011-2-cota@braap.org> Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20230124180127.1881110-27-alex.bennee@linaro.org>

2023-02-02semihosting: add O_BINARY flag in host_open for NT compatibilityEvgeny Iakovlev1-4/+4
Windows open(2) implementation opens files in text mode by default and needs a Windows-only O_BINARY flag to open files as binary. QEMU already knows about that flag in osdep and it is defined to 0 on non-Windows, so we can just add it to the host_flags for better compatibility.

2023-02-02semihosting: Write back semihosting data before completion callbackKeith Packard1-10/+10
'lock_user' allocates a host buffer to shadow a target buffer, 'unlock_user' copies that host buffer back to the target and frees the host memory. If the completion function uses the target buffer, it must be called after unlock_user to ensure the data are present. This caused the arm-compatible TARGET_SYS_READC to fail as the completion function, common_semi_readc_cb, pulled data from the target buffer which would not have been gotten the console data. I decided to fix all instances of this pattern instead of just the console_read function to make things consistent and potentially fix bugs in other cases.

We were using quite and old runner on our machines and running into issues with stalling jobs. Gitlab in the meantime now reliably provide the latest packaged versions of the runner under a stable URL. This update: - creates a per-arch subdir for builds - switches from binary tarballs to deb packages - re-uses the same binary for the secondary runner - updates distro check for second to 22.04 Note this script isn't fully idempotent as we end up accumulating runners especially during testing. However we also want to be able to run twice with different GitLab keys (e.g. project and personal) so I think we just have to be mindful of that during testing.

2023-01-31gitlab-ci.d/buildtest: Merge the --without-default-* jobsThomas Huth1-12/+5
Let's safe some CI minutes by merging these two jobs. We can now also drop "--disable-capstone" since the capstone submodule has been removed a while ago. We should rather test --disable-fdt now to check a compilation without the "dtc" submodule (for this we have to drop i386-softmmu from the target list unfortunately). Additionally, the qtests with s390x and sh4 are not read for "--without-default-devices" yet, so we can only test mips64 and avr here now.

2023-01-31tests/qtest/display-vga-test: Add proper checks if a device is availableThomas Huth1-40/+25
display-vga-test currently tries to guess the usable VGA devices according to the target architecture that is used for the test. This of course does not work if QEMU has been built with the "--without-default-devices" configure switch. To fix this, use the qtest_has_device() function for the decision instead. This way we can also consolidate most of the test functions into one single function (that takes a parameter with the device name now), except for the multihead test that tries to instantiate two devices and thus is a little bit different.

2023-01-31gitlab-ci.d/buildtest: Remove ppc-softmmu from the clang-system jobThomas Huth1-2/+1
We are also compile-testing ppc64-softmmu with clang in the "tsan-build" job, and ppc64-softmmu covers pretty much the same code as ppc-softmmu, so we should not lose much test coverage here by removing ppc-softmmu from the "clang-system" job.

2023-01-30qapi, audio: Make introspection reflect build configuration more closelyDaniel P. Berrangé4-13/+112
Currently the -audiodev accepts any audiodev type regardless of what is built in to QEMU. An error only occurs later at runtime when a sound device tries to use the audio backend. With this change QEMU will immediately reject -audiodev args that are not compiled into the binary. The QMP schema will also be introspectable to identify what is compiled in. This also helps to avoid compiling code that is not required in the binary. Note: When building the audiodevs as modules, the patch only compiles out code for modules that we don't build at all.

2023-01-30qapi, audio: add query-audiodev commandDaniel P. Berrangé2-0/+25
Way back in QEMU 4.0, the -audiodev command line option was introduced for configuring audio backends. This CLI option does not use QemuOpts so it is not visible for introspection in 'query-command-line-options', instead using the QAPI Audiodev type. Unfortunately there is also no QMP command that uses the Audiodev type, so it is not introspectable with 'query-qmp-schema' either. This introduces a 'query-audiodev' command that simply reflects back the list of configured -audiodev command line options. This alone is maybe not very useful by itself, but it makes Audiodev introspectable via 'query-qmp-schema', so that libvirt (and other upper layer tools) can discover the available audiodevs. Signed-off-by: Daniel P.
