| * sockets: Make abstract UnixSocketAddress depend on CONFIG_LINUXMarkus Armbruster2020-11-035-19/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The abstract socket namespace is a non-portable Linux extension. An attempt to use it elsewhere should fail with ENOENT (the abstract address looks like a "" pathname, which does not resolve). 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unix_listen_saddr() replaces empty @path by unique value. It obtains the value by creating and deleting a unique temporary file with mkstemp(). This is racy, as the comment explains. It's also entirely undocumented as far as I can tell. Goes back to commit d247d25f18 "sockets: helper functions for qemu (Gerd Hoffman)", v0.10.0. Since abstract socket addresses have no connection with filesystem pathnames, making them up with mkstemp() seems inappropriate. Bypass the replacement of empty @path.

The function returns a non-abstract socket address for abstract sockets (wrong) with a null @path (also wrong; a non-optional QAPI str member must never be null).

| * sockets: Fix default of UnixSocketAddress member @tightMarkus Armbruster2020-11-033-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Since the fallback version is still unsafe, I would rather keep the _qemu postfix, to make sure it's not being misused by mistake.

If no iteration fails, the function returns a value and sets no error. Okay. If exactly one iteration fails, the function returns a value and sets an error. Wrong. If multiple iterations fail, the function trips error_setv()'s assertion. Fix it to return immediately on error. Perhaps the failure to convert the driver version to UTF-8 should not be an error.

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.

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.

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.
