A just-closed channel may have a pending interrupt, and later when a new
|
||||
channel with the same channel ID is not being fully initialized, the
|
||||
pending interrupt of the previous channel with the same channel ID can run
|
||||
the channel callback on the new channel data structure, causing a crash
|
||||
of NULL pointer dereferencing.
|
||||
|
||||
Normally it’s pretty hard to reproduce the race condition, but it can
|
||||
indeed happen with specially-designed hv_sock stress test cases.

Subject: [PATCH 04/18] hv_sock: implements Hyper-V transport for Virtual
|
||||
Sockets (AF_VSOCK)
|
||||
|
||||
Hyper-V Sockets (hv_sock) supplies a byte-stream based communication
|
||||
mechanism between the host and the guest. It uses VMBus ringbuffer as the
|
||||
transportation layer.
|
||||
|
||||
With hv_sock, applications between the host (Windows 10, Windows Server
|
||||
2016 or newer) and the guest can talk with each other using the traditional
|
||||
socket APIs.
|
||||
|
||||
More info about Hyper-V Sockets is available here:
|
||||
|
||||
"Make your own integration services":
|
||||
https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/make-integration-service
|
||||
|
||||
The patch implements the necessary support in Linux guest by introducing a new
|
||||
vsock transport for AF_VSOCK.

|

|

|

+ * each other. Though the VmID is useful on the host, especially in the case
|
||||
+ * of Windows container, Linux VM doesn't need it at all.
|
||||
+ *
|
||||
+ * To make use of the AF_VSOCK infrastructure in Linux VM, we have to limit
|
||||
+ * the available GUID space of SOCKADDR_HV so that we can create a mapping
|
||||
+ * between AF_VSOCK port and SOCKADDR_HV Service GUID. The rule of writing
|
||||
+ * Hyper-V Sockets apps on the host and in Linux VM is:
|

+ *
|
||||
+ ****************************************************************************
|
||||
+ * the only valid Service GUIDs, from the perspectives of both the host and *
|
||||
+ * Linux VM, that can be connected by the other end, must conform to this *
|
||||
+ * format: <port>-facb-11e6-bd58-64006a7986d3, and the "port" must be in *
|
||||
+ * this range [0, 0x7FFFFFFF]. *
|
||||
+ ****************************************************************************
|
||||
+ *
|
||||
+ * When we write apps on the host to connect(), the GUID ServiceID is used.
|
||||
+ * When we write apps in Linux VM to connect(), we only need to specify the
|
||||
+ * port and the driver will form the GUID and use that to request the host.
|
||||
+ *
|
||||
+ * From the perspective of Linux VM:
|
||||
+ * 1. the local ephemeral port (i.e. the local auto-bound port when we call
|
||||
+ * connect() without explicit bind()) is generated by __vsock_bind_stream(),
|
||||
+ * and the range is [1024, 0xFFFFFFFF).
|
||||
+ * 2. the remote ephemeral port (i.e. the auto-generated remote port for
|
||||
+ * a connect request initiated by the host's connect()) is generated by
|
||||
+ * hvs_remote_addr_init() and the range is [0x80000000, 0xFFFFFFFF).

Subject: [PATCH 05/18] VMCI: only try to load on VMware hypervisor
|
||||
|
||||
Without the patch, vmw_vsock_vmci_transport.ko and vmw_vmci.ko can
|
||||
automatically load when an application creates an AF_VSOCK socket.
|
||||
|
||||
This is the expected good behavior on VMware hypervisor, but as we
|
||||
are adding hv_sock.ko (i.e. Hyper-V transport for AF_VSOCK), we should
|
||||
make sure vmw_vsock_vmci_transport.ko can't load on Hyper-V, otherwise
|
||||
there is a -EBUSY conflict when both vmw_vsock_vmci_transport.ko and
|
||||
hv_sock.ko try to call vsock_core_init().
|
||||
|
||||
On the other hand, hv_sock.ko can only load on Hyper-V, because it
|
||||
depends on hv_vmbus.ko, which deteces Hyper-V in hv_acpi_init().
|
||||
|
||||
KVM's vsock_virtio_transport doesn't have the issue because it doesn't
|
||||
define MODULE_ALIAS_NETPROTO(PF_VSOCK).

|
||||
|
||||
After we disable VMWare virtual sockets driver's auto-loading on Hyper-V,
|

Subject: [PATCH 08/18] hvsock: fix a race in hvs_stream_dequeue()
|
||||
|
||||
If hv_pkt_iter_next() returns a non-NULL pointer, we must update
|
||||
the recv_data_len/data_off info, otherwise the received data will
|
||||
be silently dropped, and let's fix hvs_stream_has_data() accordingly.
|
||||
|
||||
Thank Rolf for finding this!

Subject: [PATCH 10/18] Drivers: hv: vmbus: Fix rescind handling
|
||||
|
||||
Fix the rescind handling. This patch addresses the following rescind
|
||||
scenario that is currently not handled correctly:
|
||||
|
||||
If a rescind were to be received while the offer is still being
|
||||
peocessed, we will be blocked indefinitely since the rescind message
|
||||
is handled on the same work element as the offer message. Fix this
|
||||
issue.
|
||||
|
||||
I would like to thank Dexuan Cui <decui@microsoft.com> and
|
||||
Long Li <longli@microsoft.com> for working with me on this patch.

Subject: [PATCH 14/18] vmbus: fix the missed signaling in hv_signal_on_read()
|
||||
|
||||
There is an off-by-one bug here, which can cause host-to-guest write to stall.
|
||||
|
||||
When cur_write_sz == pending_sz, we shouldn't signal the host because it's
|
||||
meaningless: the ring mustn't be 100% full.
|
||||
|
||||
But when cached_write_sz == pending_sz, we must signal the host.

Subject: [PATCH 17/18] ext4: fix fault handling when mounted with -o dax,ro
|
||||
|
||||
If an ext4 filesystem is mounted with both the DAX and read-only
|
||||
options, executables on that filesystem will fail to start (claiming
|
||||
'Segmentation fault') due to the fault handler returning
|
||||
VM_FAULT_SIGBUS.
|
||||
|
||||
This is due to the DAX fault handler (see ext4_dax_huge_fault)
|
||||
attempting to write to the journal when FAULT_FLAG_WRITE is set. This is
|
||||
the wrong behavior for write faults which will lead to a COW page; in
|
||||
particular, this fails for readonly mounts.
|
||||
|
||||
This change avoids journal writes for faults that are expected to COW.
|
||||
|
||||
It might be the case that this could be better handled in
|
||||
ext4_iomap_begin / ext4_iomap_end (called via iomap_ops inside
|
||||
dax_iomap_fault). These is some overlap already (e.g. grabbing journal
|
||||
handles).
