Vmware Paravirtual SCSI emulation uses command descriptors to

process SCSI commands. These descriptors come with their ring
|

buffers. A guest could set the page count for these rings to
|

an arbitrary value, leading to infinite loop or OOB access.

Add check to avoid it.

|

In PVSCSI paravirtual SCSI bus, pvscsi_convert_sglist can take a very
|
||||
long time or go into an infinite loop due to two different bugs:
|
||||
|
||||
1) the request descriptor data length is defined to be 64 bit. While
|
||||
building SG list from a request descriptor, it gets truncated to 32bit
|
||||
in routine 'pvscsi_convert_sglist'. This could lead to an infinite loop
|
||||
situation for large 'dataLen' values, when data_length is cast to uint32_t
|
||||
and chunk_size becomes always zero. Fix this by removing the incorrect
|
||||
cast.
|
||||
|
||||
2) pvscsi_get_next_sg_elem can be called arbitrarily many times if the
|
||||
element has a zero length. Get out of the loop early when this happens,
|
||||
by introducing an upper limit on the number of SG list elements.

When processing IO request in mptsas, it uses g_new to allocate
|
||||
a 'req' object. If an error occurs before 'req->sreq' is
|
||||
allocated, It could lead to an OOB write in mptsas_free_request
|
||||
function. Use g_new0 to avoid it.

Subject: [PATCH] 9pfs: allocate space for guest originated empty strings
|
||||
|
||||
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.

Rocker network switch emulator has test registers to help debug
|
||||
DMA operations. While testing host DMA access, a buffer address
|
||||
is written to register 'TEST_DMA_ADDR' and its size is written to
|
||||
register 'TEST_DMA_SIZE'. When performing TEST_DMA_CTRL_INVERT
|
||||
test, if DMA buffer size was greater than 'INT_MAX', it leads to
|
||||
an invalid buffer access. Limit the DMA buffer size to avoid it.

Subject: [PATCH] 9pfs: fix integer overflow issue in xattr read/write
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
The v9fs_xattr_read() and v9fs_xattr_write() are passed a guest
|
||||
originated offset: they must ensure this offset does not go beyond
|
||||
the size of the extended attribute that was set in v9fs_xattrcreate().
|
||||
Unfortunately, the current code implement these checks with unsafe
|
||||
calculations on 32 and 64 bit values, which may allow a malicious
|
||||
guest to cause OOB access anyway.
|
||||
|
||||
Fix this by comparing the offset and the xattr size, which are
|
||||
both uint64_t, before trying to compute the effective number of bytes
|
||||
to read or write.
