| * qemu-io: Add generic function for reinitializing optind.Richard W.M. Jones2019-01-311-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On FreeBSD 11.2: $ nbdkit memory size=1M --run './qemu-io -f raw -c "aio_write 0 512" $nbd' Parsing error: non-numeric argument, or extraneous/unrecognized suffix -- aio_write After main option parsing, we reinitialize optind so we can parse each command. However reinitializing optind to 0 does not work on FreeBSD. What happens when you do this is optind remains 0 after the option parsing loop, and the result is we try to parse argv[optind] == argv[0] == "aio_write" as if it was the first parameter. The FreeBSD manual page says: In order to use getopt() to evaluate multiple sets of arguments, or to evaluate a single set of arguments multiple times, the variable optreset must be set to 1 before the second and each additional set of calls to getopt(), and the variable optind must be reinitialized. (From the rest of the man page it is clear that optind must be reinitialized to 1). The glibc man page says: A program that scans multiple argument vectors, or rescans the same vector more than once, and wants to make use of GNU extensions such as '+' and '-' at the start of optstring, or changes the value of POSIXLY_CORRECT between scans, must reinitialize getopt() by resetting optind to 0, rather than the traditional value of 1. (Resetting to 0 forces the invocation of an internal initialization routine that rechecks POSIXLY_CORRECT and checks for GNU extensions in optstring.) This commit introduces an OS-portability function called qemu_reset_optind which provides a way of resetting optind that works on FreeBSD and platforms that use optreset, while keeping it the same as now on other platforms. Note that the qemu codebase sets optind in many other places, but in those other places it's setting a local variable and not using getopt. This change is only needed in places where we are using getopt and the associated global variable optind. Signed-off-by: Richard W.M.

* linux-user: Fix compilation with clang 3.4Thomas Huth2019-01-221-0/+4
| | | | | | | | | | | | | Clang version 3.4.2 does not know the -Wpragmas option yet and bails out with an error when we try to disable it in linux-user/qemu.h. Fortunately, clang has a __has_warning() macro which allows us to add an explicit check for the option that we want to ignore. With that we can check for the availability of "-Waddress-of-packed-member" properly and do not need the "-Wpragmas" at all here.

| * qemu/compiler: Define QEMU_NONSTRINGPhilippe Mathieu-Daudé2019-01-181-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 8 introduced the -Wstringop-truncation checker to detect truncation by the strncat and strncpy functions (closely related to -Wstringop-overflow, which detect buffer overflow by string-modifying functions declared in <string.h>). In tandem of -Wstringop-truncation, the "nonstring" attribute was added: The nonstring variable attribute specifies that an object or member declaration with type array of char, signed char, or unsigned char, or pointer to such a type is intended to store character arrays that do not necessarily contain a terminating NUL. This is useful in detecting uses of such arrays or pointers with functions that expect NUL-terminated strings, and to avoid warnings when such an array or pointer is used as an argument to a bounded string manipulation function such as strncpy. From the GCC manual: https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html#index-nonstring-variable-attribute Add the QEMU_NONSTRING macro which checks if the compiler supports this attribute.

* xen: add a mechanism to automatically create XenDevice-s...Paul Durrant2019-01-141-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | ...that maintains compatibility with existing Xen toolstacks. Xen toolstacks instantiate PV backends by simply writing information into xenstore and expecting a backend implementation to be watching for this. This patch adds a new 'xen-backend' module to allow individual XenDevice implementations to register create and destroy functions. The creator will be called when a tool-stack instantiates a new backend in this way, and the destructor will then be called after the resulting XenDevice object is unrealized. To support this it is also necessary to add new watchers into the XenBus implementation to handle enumeration of new backends and also destruction of XenDevice-s when the toolstack sets the backend 'online' key to 0. NOTE: This patch only adds the framework. A subsequent patch will add a creator function for xen-block devices.

But if you squint enough, QTAILQ becomes a combination of a singly-linked forwards list, and another singly-linked list which goes backwards and is circular. This is the idea that lets QTAILQ implement reverse iteration: only, because the backwards list points inside the node, accessing the previous element needs to go two steps back and one forwards. What this patch does is implement it in these terms, without actually changing the in-memory layout at all. The coexistence of the two lists is realized by making QTAILQ_HEAD and QTAILQ_ENTRY unions of the forwards pointer and a generic QTailQLink node. Thq QTailQLink can walk the list in both directions; the union is needed so that the forwards pointer can have the correct type, as a sort of poor man's template. While there are other ways to get the same layout without a union, this one has the advantage of simpler operation in the debugger, because the fields tqh_first and tqe_next still exist as before the patch. Those fields are also used by scripts/qemugdb/mtree.py, so it's a good idea to preserve them. The advantage of the new representation is that the two-back-one-forward dance done by backwards accesses can be done all while operating on QTailQLinks. No casting to the head struct is needed anymore because, even though the QTailQLink's forward pointer is a void *, we can use typeof to recover the correct type. This patch only changes the implementation, not the interface. The next patch will remove the head struct name from the backwards visit macros. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* atomics: Set ATOMIC_REG_SIZE=8 for MIPS n32Paul Burton2019-01-031-2/+3
| | | | | | | | | | | | | | | | | | | | | ATOMIC_REG_SIZE is currently defined as the default sizeof(void *) for all MIPS host builds, including those using the n32 ABI. n32 is the MIPS64 ILP32 ABI and as such tcg/mips/tcg-target.h defines TCG_TARGET_REG_BITS as 64 for n32 builds. If we attempt to build QEMU for an n32 host with support for a 64b target architecture then TCG_OVERSIZED_GUEST is 0 and accel/tcg/cputlb.c attempts to use atomic_* functions. This fails because ATOMIC_REG_SIZE is 4, causing the calls to QEMU_BUILD_BUG_ON(sizeof(*ptr) > ATOMIC_REG_SIZE) in the various atomic_* functions to generate errors. Fix this by defining ATOMIC_REG_SIZE as 8 for all MIPS64 builds, which will cover both n32 (ILP32) & n64 (LP64) ABIs in much the same was as we already do for x86_64/x32.

* include: Add a comment to explain the origin of sizes' lookup tableLeonid Bloch2018-11-051-0/+18
| | | | | | | | | | | | | | | | | | | | | | The lookup table for power-of-two sizes was added in commit 540b8492618eb for the purpose of having convenient shortcuts for these sizes in cases when the literal number has to be present at compile time, and expressions as '(1 * KiB)' can not be used. One such case is the stringification of sizes. Beyond that, it is convenient to use these shortcuts for all power-of-two sizes, even if they don't have to be literal numbers. Despite its convenience, this table introduced 55 lines of "dumb" code, the purpose and origin of which are obscure without reading the message of the commit which introduced it. This patch fixes that by adding a comment to the code itself with a brief explanation for the reasoning behind this table. This comment includes the short AWK script that generated the table, so that anyone who's interested could make sure that the values in it are correct (otherwise these values look as if they were typed manually).

| | | | | | | | | | | | | | | | | | | | | | | This adds some whitespace into the option help (including indentation) and puts angle brackets around the type names. Furthermore, the list name is no longer printed as part of every line, but only once in advance, and only if the caller did not print a caption already. This patch also restores the description alignment we had before commit 9cbef9d68ee1d8d0, just at 24 instead of 16 characters like we used to. This increase is because now we have the type and two spaces of indentation before the description, and with a usual type name length of three chracters, this sums up to eight additional characters -- which means that we now need 24 characters to get the same amount of padding for most options. Also, 24 is a third of 80, which makes it kind of a round number in terminal terms. Finally, this patch amends the reference output of iotest 082 to match the changes (and thus makes it pass again).
