2020-11-03hw/misc: Add Microchip PolarFire SoC IOSCB module supportBin Meng
This creates a model for PolarFire SoC IOSCB [1] module. It actually contains lots of sub-modules like various PLLs to control different peripherals. Only the mininum capabilities are emulated to make the HSS DDR memory initialization codes happy. Lots of sub-modules are created as an unimplemented devices.

Add new commands to add and remove SSH public keys from ~/.ssh/authorized_keys. I took a different approach for testing, including the unit tests right with the code. I wanted to overwrite the function to get the user details, I couldn't easily do that over QMP. Furthermore, I prefer having unit tests very close to the code, and unit files that are domain specific (commands-posix is too crowded already).

The glib function was introduced in 2.64. It's a safer version of getpwnam, and also simpler to use than getpwnam_r. Currently, it's only use by the next patch in qemu-ga, which doesn't (well well...) need the thread safety guarantees. Since the fallback version is still unsafe, I would rather keep the _qemu postfix, to make sure it's not being misused by mistake. When/if necessary, we can implement a safer fallback and drop the _qemu suffix.

2020-11-02tests/acceptance: Add virtiofs_submounts.pyMax Reitz
This test invokes several shell scripts to create a random directory tree full of submounts, and then check in the VM whether every submount has its own ID and the structure looks as expected. (Note that the test scripts must be non-executable, so Avocado will not try to execute them as if they were tests on their own, too.) Because at this commit's date it is unlikely that the Linux kernel on the image provided by boot_linux.py supports submounts in virtio-fs, the test will be cancelled if no custom Linux binary is provided through the vmlinuz parameter. (The on-image kernel can be used by providing an empty string via vmlinuz=.) So, invoking the test can be done as follows: $ avocado run \ tests/acceptance/virtiofs_submounts.py \ -p vmlinuz=/path/to/linux/build/arch/x86/boot/bzImage This test requires root privileges (through passwordless sudo -n), because at this point, virtiofsd requires them. (If you have a timestamp_timeout period for sudoers (e.g. the default of 5 min), you can provide this by executing something like "sudo true" before invoking Avocado.)

2020-11-02virtiofsd: Announce sub-mount pointsMax Reitz
Whenever we encounter a directory with an st_dev or mount ID that differs from that of its parent, we set the FUSE_ATTR_SUBMOUNT flag so the guest can create a submount for it. We only need to do so in lo_do_lookup(). The following functions return a fuse_attr object: - lo_create(), though fuse_reply_create(): Calls lo_do_lookup(). - lo_lookup(), though fuse_reply_entry(): Calls lo_do_lookup(). - lo_mknod_symlink(), through fuse_reply_entry(): Calls lo_do_lookup(). - lo_link(), through fuse_reply_entry(): Creating a link cannot create a submount, so there is no need to check for it. - lo_getattr(), through fuse_reply_attr(): Announcing submounts when the node is first detected (at lookup) is sufficient. We do not need to return the submount attribute later. - lo_do_readdir(), through fuse_add_direntry_plus(): Calls lo_do_lookup(). Make announcing submounts optional, so submounts are only announced to the guest with the announce_submounts option. Some users may prefer the current behavior, so that the guest learns nothing about the host mount structure. (announce_submounts is force-disabled when the guest does not present the FUSE_SUBMOUNTS capability, or when there is no statx().)

2020-11-02virtiofsd: Add mount ID to the lo_inode keyMax Reitz
Using st_dev is not sufficient to uniquely identify a mount: You can mount the same device twice, but those are still separate trees, and e.g. by mounting something else inside one of them, they may differ. Using statx(), we can get a mount ID that uniquely identifies a mount. If that is available, add it to the lo_inode key.

2020-11-02migration: Postpone the kick of the fault thread after recoverPeter Xu
The new migrate_send_rp_req_pages_pending() call should greatly improve destination responsiveness because it will resync faulted address after postcopy recovery. However it is also the 1st place to initiate the page request from the main thread. One thing is overlooked on that migrate_send_rp_message_req_pages() is not designed to be thread-safe. So if we wake the fault thread before syncing all the faulted pages in the main thread, it means they can race. Postpone the wake up operation after the sync of faulted addresses.

When postcopy recover happens, we need to reset last_rb after each return of postcopy_pause_fault_thread() because that means we just got the postcopy migration continued. Unify this reset to the place right before we want to kick the fault thread again, when we get the command MIG_CMD_POSTCOPY_RESUME from source. This is actually more than that - because the main thread on destination will now be able to call migrate_send_rp_req_pages_pending() too, so the fault thread is not the only user of last_rb now. Move the reset earlier will allow the first call to migrate_send_rp_req_pages_pending() to use the reset value even if called from the main thread. (NOTE: this is not a real fix to 0c26781c09 mentioned below, however it is just a mark that when picking up 0c26781c09 we'd better have this one too; the real fix will come later) Fixes: 0c26781c09 ("migration: Sync requested pages after postcopy recovery") Tested-by: Christian Schoenebeck <qemu_oss@crudebyte.com> Signed-off-by: Peter Xu <peterx@redhat.com> Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Message-Id: <20201102153010.11979-2-peterx@redhat.com> Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com>

2020-11-02tests/qtest/npcm7xx_rng-test: Disable randomness testsPeter Maydell
The randomness tests in the NPCM7xx RNG test fail intermittently but fairly frequently. On my machine running the test in a loop: while QTEST_QEMU_BINARY=./qemu-system-aarch64 ./tests/qtest/npcm7xx_rng-test; do true; done will fail in less than a minute with an error like: ERROR:../../tests/qtest/npcm7xx_rng-test.c:256:test_first_byte_runs: assertion failed (calc_runs_p(buf.l, sizeof(buf) * BITS_PER_BYTE) > 0.01): (0.00286205989 > 0.01) (Failures have been observed on all 4 of the randomness tests, not just first_byte_runs.) It's not clear why these tests are failing like this, but intermittent failures make CI and merge testing awkward, so disable running them unless a developer specifically sets QEMU_TEST_FLAKY_RNG_TESTS when running the test suite, until we work out the cause.

2020-11-02qemu-option-trace.rst.inc: Don't use option:: markupPeter Maydell
Sphinx 3.2 is pickier than earlier versions about the option:: markup, and complains about our usage in qemu-option-trace.rst: ../../docs/qemu-option-trace.rst.inc:4:Malformed option description '[enable=]PATTERN', should look like "opt", "-opt args", "--opt args", "/opt args" or "+opt args" In this file, we're really trying to document the different parts of the top-level --trace option, which qemu-nbd.rst and qemu-img.rst have already introduced with an option:: markup. So it's not right to use option:: here anyway. Switch to a different markup (definition lists) which gives about the same formatted output. (Unlike option::, this markup doesn't produce index entries; but at the moment we don't do anything much with indexes anyway, and in any case I think it doesn't make much sense to have individual index entries for the sub-parts of the --trace option.)

2020-11-02scripts/kerneldoc: For Sphinx 3 use c:macro for macros with argumentsPeter Maydell
The kerneldoc script currently emits Sphinx markup for a macro with arguments that uses the c:function directive. This is correct for Sphinx versions earlier than Sphinx 3, where c:macro doesn't allow documentation of macros with arguments and c:function is not picky about the syntax of what it is passed. However, in Sphinx 3 the c:macro directive was enhanced to support macros with arguments, and c:function was made more picky about what syntax it accepted. When kerneldoc is told that it needs to produce output for Sphinx 3 or later, make it emit c:function only for functions and c:macro for macros with arguments. We assume that anything with a return type is a function and anything without is a macro. This fixes the Sphinx error: /home/petmay01/linaro/qemu-from-laptop/qemu/docs/../include/qom/object.h:155:Error in declarator If declarator-id with parameters (e.g., 'void f(int arg)'): Invalid C declaration: Expected identifier in nested name.

2020-11-02hw/intc/arm_gicv3_cpuif: Make GIC maintenance interrupts workPeter Maydell
In gicv3_init_cpuif() we copy the ARMCPU gicv3_maintenance_interrupt into the GICv3CPUState struct's maintenance_irq field. This will only work if the board happens to have already wired up the CPU maintenance IRQ before the GIC was realized. Unfortunately this is not the case for the 'virt' board, and so the value that gets copied is NULL (since a qemu_irq is really a pointer to an IRQState struct under the hood). The effect is that the CPU interface code never actually raises the maintenance interrupt line. Instead, since the GICv3CPUState has a pointer to the CPUState, make the dereference at the point where we want to raise the interrupt, to avoid an implicit requirement on board code to wire things up in a particular order.

2020-11-02target/arm: Get correct MMU index for other-security-statePeter Maydell
In arm_v7m_mmu_idx_for_secstate() we get the 'priv' level to pass to armv7m_mmu_idx_for_secstate_and_priv() by calling arm_current_el(). This is incorrect when the security state being queried is not the current one, because arm_current_el() uses the current security state to determine which of the banked CONTROL.nPRIV bits to look at. The effect was that if (for instance) Secure state was in privileged mode but Non-Secure was not then we would return the wrong MMU index. The only places where we are using this function in a way that could trigger this bug are for the stack loads during a v8M function-return and for the instruction fetch of a v8M SG insn. Fix the bug by expanding out the M-profile version of the arm_current_el() logic inline so it can use the passed in secstate rather than env->v7m.secure.

This is caused by passing the wrong value to the read_memory_func(). The intention is that at this point in the loop the 'cap_buf' buffer already contains 'csize' bytes of data for the instruction at guest addr 'pc', and we want to read in an extra 'tsize' bytes. Those extra bytes are therefore at 'pc + csize', not 'pc'. On the first time through the loop 'csize' happens to be zero, so the initial read of 32 bytes into cap_buf is correct and as long as the disassembly never needs to read more data we return the correct information. Use the correct guest address in the call to read_memory_func().
