2020-05-25xen/9pfs: yield when there isn't enough room on the ringStefano Stabellini1-6/+25
Instead of truncating replies, which is problematic, wait until the client reads more data and frees bytes on the reply ring. Do that by calling qemu_coroutine_yield(). The corresponding qemu_coroutine_enter_if_inactive() is called from xen_9pfs_bh upon receiving the next notification from the client. We need to be careful to avoid races in case xen_9pfs_bh and the coroutine are both active at the same time. In xen_9pfs_bh, wait until either the critical section is over (ring->co == NULL) or until the coroutine becomes inactive (qemu_coroutine_yield() was called) before continuing. Then, simply wake up the coroutine if it is inactive.

A guest user may set channel frame count via es1370_write() such that, in es1370_transfer_audio(), total frame count 'size' is lesser than the number of frames that are processed 'cnt'. int cnt = d->frame_cnt >> 16; int size = d->frame_cnt & 0xffff; if (size < cnt), it results in incorrect calculations leading to OOB access issue(s).

2020-05-259p: Lock directory streams with a CoMutexGreg Kurz1-4/+4
Locking was introduced in QEMU 2.7 to address the deprecation of readdir_r(3) in glibc 2.24. It turns out that the frontend code is the worst place to handle a critical section with a pthread mutex: the code runs in a coroutine on behalf of the QEMU mainloop and then yields control, waiting for the fsdev backend to process the request in a worker thread. If the client resends another readdir request for the same fid before the previous one finally unlocked the mutex, we're deadlocked. This never bit us because the linux client serializes readdir requests for the same fid, but it is quite easy to demonstrate with a custom client. A good solution could be to narrow the critical section in the worker thread code and to return a copy of the dirent to the frontend, but this causes quite some changes in both 9p.c and codir.c. So, instead of that, in order for people to easily backport the fix to older QEMU versions, let's simply use a CoMutex since all the users for this sit in coroutines.

2020-05-22hw/block/pflash_cfi01: Document use of non-CFI compliant command '0x00'Philippe Mathieu-Daudé1-5/+13
The command 0x00 is used by this model since its origin (commit 05ee37ebf630). In this commit the command is described with a amusing '/* ??? */' comment, probably meaning 'FIXME'. switch (cmd) { case 0x00: /* ??? */ ... This comment survived 12 years because the 0x00 value is indeed not specified by the CFI open standard (as of this commit). The 'cmd' field is transfered during migration. To keep the migration feature working with older QEMU version, we have to take a lot of care with migrated field. We figured out it is too late to remove a non-specified value from this model (this would make migration review very complex). It is however not too late to improve the documentation. Add few comments to remember this is a special value related to QEMU, and we won't find information about it on the CFI spec.

2020-05-18ramfb: fix size calculationGerd Hoffmann1-9/+10
size calculation isn't correct with guest-supplied stride, the last display line isn't accounted for correctly. For the typical case of stride > linesize (add padding) we error on the safe side (calculated size is larger than actual size). With stride < linesize (scanlines overlap) the calculated size is smaller than the actual size though so our guest memory mapping might end up being too small. While being at it also fix ramfb_create_display_surface to use hwaddr for the parameters. That way all calculation are done with hwaddr type and we can't get funny effects from type castings.
