2022-01-07hw/intc/arm_gicv3_its: Don't return early in extract_table_params() loopPeter Maydell1-2/+2
In extract_table_params() we process each GITS_BASER<n> register. If the register's Valid bit is not set, this means there is no in-guest-memory table and so we should not try to interpret the other fields in the register. This was incorrectly coded as a 'return' rather than a 'break', so instead of looping round to process the next GITS_BASER<n> we would stop entirely, treating any later tables as being not valid also. This has no real guest-visible effects because (since we don't have GITS_TYPER.HCC != 0) the guest must in any case set up all the GITS_BASER<n> to point to valid tables, so this only happens in an odd misbehaving-guest corner case. Fix the check to 'break', so that we leave the case statement and loop back around to the next GITS_BASER<n>.

2022-01-07hw/intc/arm_gicv3_its: Remove maxids union from TableDescPeter Maydell2-14/+11
The TableDesc struct defines properties of the in-guest-memory tables which the guest tells us about by writing to the GITS_BASER<n> registers. This struct currently has a union 'maxids', but all the fields of the union have the same type (uint32_t) and do the same thing (record one-greater-than the maximum ID value that can be used as an index into the table). We're about to add another table type (the GICv4 vPE table); rather than adding another specifically-named union field for that table type with the same type as the other union fields, remove the union entirely and just have a 'uint32_t max_ids' struct field.

2022-01-07hw/intc/arm_gicv3_its: Correct off-by-one bounds check on rdbasePeter Maydell1-2/+2
The checks in the ITS on the rdbase values in guest commands are off-by-one: they permit the guest to pass us a value equal to s->gicv3->num_cpu, but the valid values are 0...num_cpu-1. This meant the guest could cause us to index off the end of the s->gicv3->cpu[] array when calling gicv3_redist_process_lpi(), and we would probably crash. (This is not a security bug, because this code is only usable with emulation, not with KVM.)

2022-01-06linux-user/signal: Map exit signals in SIGCHLD siginfo_tMatthias Schiffer1-1/+6
When converting a siginfo_t from waitid(), the interpretation of si_status depends on the value of si_code: For CLD_EXITED, it is an exit code and should be copied verbatim. For other codes, it is a signal number (possibly with additional high bits from ptrace) that should be mapped. This code was previously changed in commit 1c3dfb506ea3 ("linux-user/signal: Decode waitid si_code"), but the fix was incomplete. Tested with the following test program: #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <sys/wait.h> int main() { pid_t pid = fork(); if (pid == 0) { exit(12); } else { siginfo_t siginfo = {}; waitid(P_PID, pid, &siginfo, WEXITED); printf("Code: %d, status: %d\n", (int)siginfo.si_code, (int)siginfo.si_status); } pid = fork(); if (pid == 0) { raise(SIGUSR2); } else { siginfo_t siginfo = {}; waitid(P_PID, pid, &siginfo, WEXITED); printf("Code: %d, status: %d\n", (int)siginfo.si_code, (int)siginfo.si_status); } } Output with an x86_64 host and mips64el target before 1c3dfb506ea3 (incorrect: exit code 12 is translated like a signal): Code: 1, status: 17 Code: 2, status: 17 After 1c3dfb506ea3 (incorrect: signal number is not translated): Code: 1, status: 12 Code: 2, status: 12 With this patch: Code: 1, status: 12 Code: 2, status: 17 Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net> Reviewed-by: Laurent Vivier <laurent@vivier.eu> Message-Id: <81534fde7cdfc6acea4889d886fbefdd606630fb.1635019124.git.mschiffer@universe-factory.net> Signed-off-by: Laurent Vivier <laurent@vivier.eu>

2022-01-05docs/tools/qemu-trace-stap.rst: Do not hard-code the QEMU binary nameThomas Huth1-12/+12
In downstream, we want to use a different name for the QEMU binary, and some people might also use the docs for non-x86 binaries, that's why we already created the |qemu_system| placeholder in the past. Use it now in the stap trace doc, too. Message-Id: <20220104103319.179870-1-thuth@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Thomas Huth <thuth@redhat.com>
2022-01-05gitlab-ci: Enable docs in the centos jobThomas Huth1-1/+1
We just ran into a problem that the docs don't build on RHEL8 / CentOS 8 anymore. Seems like these distros are using one of the oldest Sphinx versions that we still have to support. Thus enable the docs build in the CI on CentOS so that such bugs don't slip in so easily again.

2022-01-05qemu-options: Remove the deprecated -no-quit optionThomas Huth4-21/+8
This option was just a wrapper around the -display ...,window-close=off parameter, and the name "no-quit" is rather confusing compared to "window-close" (since there are still other means to quit the emulator), so let's remove this now.
