2011-10-21macvtap: Fix the minor device number allocationEric W. Biederman
On systems that create and delete lots of dynamic devices the 31bit linux ifindex fails to fit in the 16bit macvtap minor, resulting in unusable macvtap devices. I have systems running automated tests that that hit this condition in just a few days. Use a linux idr allocator to track which mavtap minor numbers are available and and to track the association between macvtap minor numbers and macvtap network devices. Remove the unnecessary unneccessary check to see if the network device we have found is indeed a macvtap device. With macvtap specific data structures it is impossible to find any other kind of networking device. Increase the macvtap minor range from 65536 to the full 20 bits that is supported by linux device numbers. It doesn't solve the original problem but there is no penalty for a larger minor device range. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S.

2011-10-21macvtap: Rewrite macvtap_newlink so the error handling works.Eric W. Biederman
Place macvlan_common_newlink at the end of macvtap_newlink because failing in newlink after registering your network device is not supported. Move device_create into a netdevice creation notifier.

To see if it is appropriate to enable the macvtap zero copy feature don't test the lowerdev network device flags. Instead test the macvtap network device flags which are a direct copy of the lowerdev flags. This is important because nothing holds a reference to lowerdev and on a very bad day we lowerdev could be a pointer to stale memory. Signed-off-by: Eric W.

2011-10-21macvtap: Close a race between macvtap_open and macvtap_dellink.Eric W. Biederman
There is a small window in macvtap_open between looking up a networking device and calling macvtap_set_queue in which macvtap_del_queues called from macvtap_dellink. After calling macvtap_del_queues it is totally incorrect to allow macvtap_set_queue to proceed so prevent success by reporting that all of the available queues are in use. Signed-off-by: Eric W.

Problem using big mtu around 4096 bytes is you end allocating (4096 +NET_SKB_PAD + NET_IP_ALIGN + sizeof(struct skb_shared_info) bytes -> 8192 bytes : order-1 pages It's better to limit the mtu to SKB_MAX_HEAD(NET_SKB_PAD), to have no more than one page per skb. Also the patch changes the netdev_alloc_skb_ip_align() done in init_dma_desc_rings() and uses a variant allowing GFP_KERNEL allocations allowing the driver to load even in case of memory pressure.

2011-10-19stmmac: add CHAINED descriptor mode support (V4)Giuseppe CAVALLARO
This patch enhances the STMMAC driver to support CHAINED mode of descriptor. STMMAC supports DMA descriptor to operate both in dual buffer(RING) and linked-list(CHAINED) mode. In RING mode (default) each descriptor points to two data buffer pointers whereas in CHAINED mode they point to only one data buffer pointer. In CHAINED mode each descriptor will have pointer to next descriptor in the list, hence creating the explicit chaining in the descriptor itself, whereas such explicit chaining is not possible in RING mode. First version of this work has been done by Rayagond. Then the patch has been reworked avoiding ifdef inside the C code. A new header file has been added to define all the functions needed for managing enhanced and normal descriptors. In fact, these have to be specialized according to the ring/chain usage. Two new C files have been also added to implement the helper routines needed to manage: jumbo frames, chain and ring setup (i.e. desc3).

2011-10-19bonding: fix wrong port enabling in 802.3adFlavio Leitner
The port shouldn't be enabled unless its current MUX state is DISTRIBUTING which is correctly handled by ad_mux_machine(), otherwise the packet sent can be lost because the other end may not be ready. The issue happens on every port initialization, but as the ports are expected to move quickly to DISTRIBUTING, it doesn't cause much problem. However, it does cause constant packet loss if the other peer has the port configured to stay in STANDBY (i.e. SYNC set to OFF). Signed-off-by: Flavio Leitner <fbl@redhat.com> Signed-off-by: David S.

2011-10-19phylib: Modify Vitesse RGMII skew settingsAndy Fleming
The Vitesse driver was using the RGMII_ID interface type to determine if skew was necessary. However, we want to move away from using that interface type, as it's really a property of the board's PHY connection. However, some boards depend on it, so we want to support it, while allowing new boards to use the more flexible "fixups" approach. To do this, we extract the code which adds skew into its own function, and call that function when RGMII_ID has been selected. Another side-effect of this change is that if your PHY has skew set already, it doesn't clear it. This way, the fixup code can modify the register without config_init then clearing it.
