treewide: Convert del_timer*() to timer_shutdown*()
Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed.
The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case.
This was created by using a coccinelle script and the following commands:
$ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); )
$ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch

sparc/vio: make remove callback return void
The driver core ignores the return value of struct bus_type::remove() because there is only little that can be done. To simplify the quest to make this function return void, let struct vio_driver::remove() return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and should prevent that future driver authors consider returning an error code.
Note there are two nominally different implementations for a vio bus: one in arch/sparc/kernel/vio.c and the other in arch/powerpc/platforms/pseries/vio.c. This patch only addresses the former.

net: remove 'fallback' argument from dev->ndo_select_queue()
After the previous patch, all the callers of ndo_select_queue() provide as a 'fallback' argument netdev_pick_tx. The only exceptions are nested calls to ndo_select_queue(), which pass down the 'fallback' available in the current scope - still netdev_pick_tx.
We can drop such argument and replace fallback() invocation with netdev_pick_tx(). This avoids an indirect call per xmit packet in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen) with device drivers implementing such ndo. It also clean the code a bit.
Tested with ixgbe and CONFIG_FCOE=m

sunvnet: restrict advertized checksum offloads to just IP
As much as we'd like to play well with others, we really aren't handling the checksums on non-IP protocol packets very well. This is easily seen when trying to do TCP over ipv6 - the checksums are garbage.
Here we restrict the checksum feature flag to just IP traffic so that we aren't given work we can't yet do.

sunvnet: add stats to track ldom to ldom packets and bytes
In this driver, there is a "port" created for the connection to each of the other ldoms; a netdev queue is mapped to each port, and they are collected under a single netdev. The generic netdev statistics show us all the traffic in and out of our network device, but don't show individual queue/port stats. This patch breaks out the traffic counts for the individual ports and gives us a little view into the state of those connections.

ldmvsw: Make sunvnet_common compatible with ldmvsw
Modify sunvnet common code and data structures to be compatible with both sunvnet and ldmvsw drivers.
Details:
Sunvnet operates on "vnet-port" nodes which appear in the Machine Description (MD) in a guest domain. Ldmvsw operates on "vsw-port" nodes which appear in the MD of a service domain.
A difference between the sunvnet driver and the ldmvsw driver is the sunvnet driver creates a network interface (i.e. a struct net_device) for every vnet-port *parent* "network" node. Several vnet-ports may appear under this common parent network node - each corresponding to a common parent network interface. Conversely, since bridge/vswitch software will need to interface with every vsw-port in a system, the ldmvsw driver creates a network interface (i.e. a struct net_device) for every vsw-port - not every parent node as with sunvnet. This difference required some special handling in the common code as explained below.
There are 2 key data structures used by the sunvnet and ldmvsw drivers (which are now found in sunvnet_common.h):
1. struct vnet_port This structure represents a vnet-port node in sunvnet and a vsw-port in the ldmvsw driver.
2. struct vnet This structure represents a parent "network" node in sunvnet and a parent "virtual-network-switch" node in ldmvsw.
Since the sunvnet driver allocates a net_device for every parent "network" node, a net_device member appears in the struct vnet. Since the ldmvsw driver allocates a net_device for every port, a net_device member was added to the vnet_port. The common code distinguishes which structure net_device member to use by checking a 'vsw' bit that was added to the vnet_port structure. See the VNET_PORT_TO_NET_DEVICE() marco in sunvnet_common.h.
The netdev_priv() in sunvnet is allocated as a vnet. The netdev_priv() in ldmvsw is a vnet_port. Therefore, any place in the common code where a netdev_priv() call was made, a wrapper function was implemented in each driver to first get the vnet and/or vnet_port (in a driver specific way) and pass them as newly added parameters to the common functions (see wrapper funcs: vnet_set_rx_mode() and vnet_poll_controller()). Since these wrapper functions call __tx_port_find(), __tx_port_find() was moved from the common code back into sunvnet.c. Note - ldmvsw.c does not require this function.
These changes also required that port_is_up() be made into a common function and thus it was given a _common suffix and exported like the other common functions.
A wrapper function was also added for vnet_start_xmit_common() to pass a driver-specific function arg to return the port associated with a given struct sk_buff and struct net_device. This was required because vnet_start_xmit_common() grabs a lock prior to getting the associated port. Using a function pointer arg allowed the code to work unchanged without risking changes to the non-trivial locking logic in vnet_start_xmit_common().

ldmvsw: Split sunvnet driver into common code
Split sunvnet.c into sunvnet.c and sunvnet_common.c.
Details:
Since the sunvnet and ldmvsw drivers will both use common sunvnet code, move the functions (and support functions) anticipated to be common code from sunvnet.c to sunvnet_common.c. Similarly, sunvnet.h was renamed to sunvnet_common.h. The sunvnet_common.c code will be compiled into the kernel and act as a library of functions that are linked by either (or both) drivers when loaded.
Function names for external functions in sunvnet_common.c (to be called by both the sunvnet and ldmvsw drivers) were tagged with a "_common" suffix to clearly designate them as common functions.
No functional changes as of yet... just moved code verbatim to the new sunvnet_common.c/h files.
Makefile/Kconfig support added to build sunvnet_common.c file. The code is included in the kernel if SUN_LDOMS is defined/selected.
NOTE - per the SubmittingPatches documentation, since the code was just moved from one file another, the code was NOT checkpatch'd in this commit to aid in review.
