2019-10-109p: Added virtfs option 'multidevs=remap|forbid|warn'Antonios Motakis
'warn' (default): Only log an error message (once) on host if more than one device is shared by same export, except of that just ignore this config error though. This is the default behaviour for not breaking existing installations implying that they really know what they are doing. 'forbid': Like 'warn', but except of just logging an error this also denies access of guest to additional devices. 'remap': Allows to share more than one device per export by remapping inodes from host to guest appropriately. To support multiple devices on the 9p share, and avoid qid path collisions we take the device id as input to generate a unique QID path. The lowest 48 bits of the path will be set equal to the file inode, and the top bits will be uniquely assigned based on the top 16 bits of the inode and the device id.

2019-08-16Include qemu/main-loop.h lessMarkus Armbruster
In my "build everything" tree, changing qemu/main-loop.h triggers a recompile of some 5600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h).

Include qemu/main-loop.h only where it's needed. Touching it now recompiles only some 1700 objects. For block/aio.h and qemu/event_notifier.h, these numbers drop from 5600 to 2800.

2019-05-17fsdev: Error out when unsupported option is passedGreg Kurz
Each fsdriver only supports a subset of the options that can be passed to -fsdev. Unsupported options are simply ignored. This could cause the user to erroneously think QEMU has a bug.

2018-02-08coroutine-lock: make qemu_co_enter_next thread-safePaolo Bonzini
qemu_co_queue_next does not need to release and re-acquire the mutex, because the queued coroutine does not run immediately. However, this does not hold for qemu_co_enter_next. Now that qemu_co_queue_wait can synchronize (via QemuLockable) with code that is not running in coroutine context, it's important that code using qemu_co_enter_next can easily use a standardized locking idiom. First of all, qemu_co_enter_next must use aio_co_wake to restart the coroutine. Second, the function gains a second argument, a QemuLockable*, and the comments of qemu_co_queue_next and qemu_co_queue_restart_all are adjusted to clarify the difference.

2017-06-299pfs: local: Add support for custom fmode/dmode in 9ps mapped security modesTobias Schramm
In mapped security modes, files are created with very restrictive permissions (600 for files and 700 for directories). This makes file sharing between virtual machines and users on the host rather complicated. Imagine eg. a group of users that need to access data produced by processes on a virtual machine. Giving those users access to the data will be difficult since the group access mode is always 0. This patch makes the default mode for both files and directories configurable.

2016-10-179pfs: allocate space for guest originated empty stringsLi Qiang
If a guest sends an empty string paramater to any 9P operation, the current code unmarshals it into a V9fsString equal to { .size = 0, .data = NULL }. This is unfortunate because it can cause NULL pointer dereference to happen at various locations in the 9pfs code. And we don't want to check str->data everywhere we pass it to strcmp() or any other function which expects a dereferenceable pointer. This patch enforces the allocation of genuine C empty strings instead, so callers don't have to bother. Out of all v9fs_iov_vunmarshal() users, only v9fs_xattrwalk() checks if the returned string is empty. It now uses v9fs_string_size() since name.data cannot be NULL anymore.
