* util: Specialize flush_idcache_range for aarch64Richard Henderson2021-01-071-0/+69
| | | | | | | | | | | | | For darwin, the CTR_EL0 register is not accessible, but there are system routines that we can use. For other hosts, copy the single pointer implementation from libgcc and modify it to support the double pointer interface we require. This halves the number of cache operations required when split-rwx is enabled. Reviewed-by: Joelle van Dyne <j@getutm.app> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
* util: Enhance flush_icache_range with separate data pointerRichard Henderson2021-01-072-19/+27
| | | | | | | | | | | | | We are shortly going to have a split rw/rx jit buffer. Depending on the host, we need to flush the dcache at the rw data pointer and flush the icache at the rx code pointer. For now, the two passed pointers are identical, so there is no effective change in behaviour.

| * cfi: Initial support for cfi-icall in QEMUDaniele Buono2021-01-022-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LLVM/Clang, supports runtime checks for forward-edge Control-Flow Integrity (CFI). CFI on indirect function calls (cfi-icall) ensures that, in indirect function calls, the function called is of the right signature for the pointer type defined at compile time. For this check to work, the code must always respect the function signature when using function pointer, the function must be defined at compile time, and be compiled with link-time optimization. This rules out, for example, shared libraries that are dynamically loaded (given that functions are not known at compile time), and code that is dynamically generated at run-time. This patch: 1) Introduces the CONFIG_CFI flag to support cfi in QEMU 2) Introduces a decorator to allow the definition of "sensitive" functions, where a non-instrumented function may be called at runtime through a pointer. The decorator will take care of disabling cfi-icall checks on such functions, when cfi is enabled. 3) Marks functions currently in QEMU that exhibit such behavior, in particular: - The function in TCG that calls pre-compiled TBs - The function in TCI that interprets instructions - Functions in the plugin infrastructures that jump to callbacks - Functions in util that directly call a signal handler Signed-off-by: Daniele Buono <dbuono@linux.vnet.ibm.com> Acked-by: Alex Bennée <alex.bennee@linaro.org Message-Id: <20201204230615.2392-3-dbuono@linux.vnet.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* qapi: Use QAPI_LIST_PREPEND() where possibleEric Blake2020-12-191-10/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | Anywhere we create a list of just one item or by prepending items (typically because order doesn't matter), we can use QAPI_LIST_PREPEND(). But places where we must keep the list in order by appending remain open-coded until later patches. Note that as a side effect, this also performs a cleanup of two minor issues in qga/commands-posix.c: the old code was performing new = g_malloc0(sizeof(*ret)); which 1) is confusing because you have to verify whether 'new' and 'ret' are variables with the same type, and 2) would conflict with C++ compilation (not an actual problem for this file, but makes copy-and-paste harder).

* qemu-option: pass QemuOptsList to opts_accepts_anyPaolo Bonzini2020-12-151-10/+13
| | | | | | | | | | | | | | | A QemuOptsList can be of one of two kinds: either it is pre-validated, or it accepts any key and validation happens somewhere else (typically in a Visitor or against a list of QOM properties). opts_accepts_any returns true if a QemuOpts instance was created from a QemuOptsList of the latter kind, but there is no function to do the check on a QemuOptsList. Since this property comes from the QemuOptsList and almost all callers of opts_accepts_any use opts->list anyway, modify the function to accept QemuOptsList.

| * qemu-option: restrict qemu_opts_set to merge-lists QemuOptsPaolo Bonzini2020-12-101-6/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qemu_opts_set is used to create default network backends and to parse sugar options -kernel, -initrd, -append, -bios and -dtb. These are very different uses: I would *expect* a function named qemu_opts_set to set an option in a merge-lists QemuOptsList, such as -kernel, and possibly to set an option in a non-merge-lists QemuOptsList with non-NULL id, similar to -set. However, it wouldn't *work* to use qemu_opts_set for the latter because qemu_opts_set uses fail_if_exists==1. So, for non-merge-lists QemuOptsList and non-NULL id, the semantics of qemu_opts_set (fail if the (QemuOptsList, id) pair already exists) are debatable. On the other hand, I would not expect qemu_opts_set to create a non-merge-lists QemuOpts with a single option; which it does, though. For this case of non-merge-lists QemuOptsList and NULL id, qemu_opts_set hardly adds value over qemu_opts_parse. It does skip some parsing and unescaping, but that's not needed when creating default network backends. So qemu_opts_set has warty behavior for non-merge-lists QemuOptsList if id is non-NULL, and it's mostly pointless if id is NULL. My solution to keeping the API as simple as possible is to limit qemu_opts_set to merge-lists QemuOptsList. For them, it's useful (we don't want comma-unescaping for -kernel) *and* has sane semantics. Network backend creation is switched to qemu_opts_parse. qemu_opts_set is now only used on merge-lists QemuOptsList... except in the testcase, which is changed to use a merge-list QemuOptsList. With this change we can also remove the id parameter. With the parameter always NULL, we know that qemu_opts_create cannot fail and can pass &error_abort to it.

We report this failure like Failed to connect socket abc: No such file or directory Tolerable, although ENOTSUP would be better. However, introspection lies: it has @abstract regardless of host support. Easy enough to fix: since Linux provides them since 2.2, 'if': 'defined(CONFIG_LINUX)' should do. The above failure becomes Parameter 'backend.data.addr.data.abstract' is unexpected I consider this an improvement.

* | sockets: Fix default of UnixSocketAddress member @tightMarkus Armbruster2020-11-031-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An optional bool member of a QAPI struct can be false, true, or absent. The previous commit demonstrated that socket_listen() and socket_connect() are broken for absent @tight, and indeed QMP chardev- add also defaults absent member @tight to false instead of true. In C, QAPI members are represented by two fields, has_MEMBER and MEMBER. We have: has_MEMBER MEMBER false true false true true true absent false false/ignore When has_MEMBER is false, MEMBER should be set to false on write, and ignored on read. For QMP, the QAPI visitors handle absent @tight by setting both @has_tight and @tight to false. unix_listen_saddr() and unix_connect_saddr() however use @tight only, disregarding @has_tight. This is wrong and means that absent @tight defaults to false whereas it should default to true. The same is true for @has_abstract, though @abstract defaults to false and therefore has the same behavior for all of QMP, HMP and CLI. Fix unix_listen_saddr() and unix_connect_saddr() to check @has_abstract/@has_tight, and to default absent @tight to true. However, this is only half of the story. HMP chardev-add and CLI -chardev so far correctly defaulted @tight to true, but defaults to false again with the above fix for HMP and CLI. In fact, the "tight" and "abstract" options now break completely. Digging deeper, we find that qemu_chr_parse_socket() also ignores @has_tight, leaving it false when it sets @tight. That is also wrong, but the two wrongs cancelled out. Fix qemu_chr_parse_socket() to set @has_tight and @has_abstract; writing testcases for HMP and CLI is left for another day.

* | util/vhost-user-server: use static library in meson.buildStefan Hajnoczi2020-10-231-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't compile contrib/libvhost-user/libvhost-user.c again. Instead build the static library once and then reuse it throughout QEMU. Also switch from CONFIG_LINUX to CONFIG_VHOST_USER, which is what the vhost-user tools (vhost-user-gpu, etc) do.
