2023-02-17net: stream: add a new option to automatically reconnectLaurent Vivier
In stream mode, if the server shuts down there is currently no way to reconnect the client to a new server without removing the NIC device and the netdev backend (or to reboot). This patch introduces a reconnect option that specifies a delay to try to reconnect with the same parameters. Add a new test in qtest to test the reconnect option and the connect/disconnect events.

2023-02-16fuzz: remove fork-fuzzing scaffoldingAlexander Bulekov
Fork-fuzzing provides a few pros, but our implementation prevents us from using fuzzers other than libFuzzer, and may be causing issues such as coverage-failure builds on OSS-Fuzz. It is not a great long-term solution as it depends on internal implementation details of libFuzzer (which is no longer in active development). Remove it in favor of other methods of resetting state between inputs. Signed-off-by: Alexander Bulekov <alxndr@bu.edu> Reviewed-by: Darren Kenny <darren.kenny@oracle.com>

2023-02-16fuzz/generic-fuzz: add a limit on DMA bytes writtenAlexander Bulekov
As we have repplaced fork-based fuzzing, with reboots - we can no longer use a timeout+exit() to avoid slow inputs. Libfuzzer has its own timer that it uses to catch slow inputs, however these timeouts are usually seconds-minutes long: more than enough to bog-down the fuzzing process. However, I found that slow inputs often attempt to fill overly large DMA requests. Thus, we can mitigate most timeouts by setting a cap on the total number of DMA bytes written by an input.

2023-02-16tests/avocado: retire the Aarch64 TCG tests from boot_linux.pyAlex Bennée
The two TCG tests for GICv2 and GICv3 are very heavy weight distros that take a long time to boot up, especially for an --enable-debug build. The total code coverage they give is: Overall coverage rate: lines......: 11.2% (59584 of 530123 lines) functions..: 15.0% (7436 of 49443 functions) branches...: 6.3% (19273 of 303933 branches) We already get pretty close to that with the machine_aarch64_virt tests which only does one full boot (~120s vs ~600s) of alpine. We expand the kernel+initrd boot (~8s) to test both GICs and also add an RNG device and a block device to generate a few IRQs and exercise the storage layer. With that we get to a coverage of: Overall coverage rate: lines......: 11.0% (58121 of 530123 lines) functions..: 14.9% (7343 of 49443 functions) branches...: 6.0% (18269 of 303933 branches) which I feel is close enough given the massive time saving. If we want to target any more sub-systems we can use lighter weight more directed tests.

The code currently uses -nostartfiles, but this does not prevent linking with libc. On Fedora there is no cross-libc, so the linking step fails. Fix by using the more comprehensive -nostdlib (that's also what probe_target_compiler() checks for as well).

2023-02-11libqtest: ensure waitpid() is only called oncePaolo Bonzini
If a test aborts after qtest_wait_qemu() is called, the SIGABRT hooks are still in place and waitpid() is called again. The second time it is called, the process does not exist anymore and the system call fails. Move the s->qemu_pid = -1 assignment to qtest_wait_qemu() to make it idempotent, and anyway remove the SIGABRT hook as well to avoid that qtest_check_status() is called twice. Because of the extra call, qtest_remove_abrt_handler() now has to be made idempotent as well. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2023-02-11target/i386: fix ADOX followed by ADCXPaolo Bonzini
When ADCX is followed by ADOX or vice versa, the second instruction's carry comes from EFLAGS and the condition codes use the CC_OP_ADCOX operation. Retrieving the carry from EFLAGS is handled by this bit of gen_ADCOX: tcg_gen_extract_tl(carry_in, cpu_cc_src, ctz32(cc_op == CC_OP_ADCX ? CC_C : CC_O), 1); Unfortunately, in this case cc_op has been overwritten by the previous "if" statement to CC_OP_ADCOX. This works by chance when the first instruction is ADCX; however, if the first instruction is ADOX, ADCX will incorrectly take its carry from OF instead of CF. Fix by moving the computation of the new cc_op at the end of the function. The included exhaustive test case fails without this patch and passes afterwards. Because ADCX/ADOX need not be invoked through the VEX prefix, this regression bisects to commit 16fc5726a6e2 ("target/i386: reimplement 0x0f 0x38, add AVX", 2022-10-18). However, the mistake happened a little earlier, when BMI instructions were rewritten using the new decoder framework.
