2014-08-30stmmac: fix dma api misuseGiuseppe CAVALLARO5-27/+79
Enabling DMA_API_DEBUG, warnings are reported at runtime because the device driver frees DMA memory with wrong functions and it does not call dma_mapping_error after mapping dma memory. The first problem is fixed by of introducing a flag that helps us keeping track which mapping technique was used, so that we can use the right API for unmap. This approach was inspired by the e1000 driver, which uses a similar technique.

2014-08-30stmmac: ptp: fix the reference clockGiuseppe CAVALLARO3-6/+18
The PTP reference clock, used for setting the addend in the Timestamp Addend Register, was erroneously hard-coded (as reported in the databook just as example). The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a reference clock (clk_ptp_ref_i) that can be passed from the platform. If not passed, the main driver clock will be used as default; note that this can be fine on some platforms. Note that, prior this patch, using the old STMMAC_SYSCLOCK on some platforms, as side effect, the ptp clock can move faster/slower than the system clock.

2014-08-30stmmac: prevent false carrier sense detectionGiuseppe CAVALLARO1-1/+1
This patch is to w/a a problem that happens on some boxes when run at 10Mbps Half duplex mode. During the transmission the CSR signal is asserted for some time and the frames aborted because of carrier sense error. This is reported by MMC HW counter: txcarrier signal. This actually is a false carrier so the frames are good and there is no reason to ask for dropping them. This patch so disables the Carrier Sense During Transmission and this means that the MAC transmitter ignore the CRS signal during frame transmission in Half-Duplex mode.

2014-08-26xen-netback: move netif_napi_add before binding interruptWei Liu1-3/+3
Interrupt is enabled when bind_interdomain_evtchn_to_irqhandler returns. If there's interrupt pending interrupt handler is invoked. NAPI needs to be initialised before binding interrupt otherwise the interrupt handler will try to scheduling a NAPI instance that is not initialised yet, resulting in kernel OOPS. This fixes a regression introduced in ea2c5e13 ("xen-netback: move NAPI add/remove calls"). Ideally function calls to create kthreads should also be moved before binding but I intent to fix this regression with minimal changes and refactor the code with another patch.

2014-08-26qlge: Fix TSO for non-accelerated vlan trafficVlad Yasevich1-2/+3
This device claims TSO support for vlans. It also allows a user to control vlan acceleration offloading. As such, it is possible to turn off vlan acceleration and configure a vlan which will continue to send TSO traffic. In such situation the packet passed down the the device will contain a vlan header and skb->protocol will be set to ETH_P_8021Q. The device assumes that skb->protocol contains network protocol value and uses that value to set up TSO information. This results in corrupted frames sent on the wire. This patch extracts the protocol value correctly by using a vlan_get_protocol() helper and corrects corrupt TSO frames.

2014-08-26mvneta: Fix TSO and checksum for non-acceleration vlan trafficVlad Yasevich1-3/+4
This driver doesn't appear to support vlan acceleration at all. However, it does claim to support TSO and IP checksums for vlan devices. Thus any configured vlan device would end up passing down partial checksums or TSO frames. The driver also uses the value from skb->protocol to determine TSO and checksum offload information, but assumes that skb->protocol holds the l3 protocol information. As a result, vlan traffic with partial checksums or TSO will fail those checks and TSO will not happen. Fix this by using vlan_get_protocol() helper.

2014-08-23vxlan: fix incorrect initializer in union vxlan_addrGerhard Stenzel1-4/+4
The first initializer in the following union vxlan_addr ipa = { .sin.sin_addr.s_addr = tip, .sa.sa_family = AF_INET, }; is optimised away by the compiler, due to the second initializer, therefore initialising .sin.sin_addr.s_addr always to 0. This results in netlink messages indicating a L3 miss never contain the missed IP address. This was observed with GCC 4.8 and 4.9. I do not know about previous versions. The problem affects user space programs relying on an IP address being sent as part of a netlink message indicating a L3 miss. Changing .sa.sa_family = AF_INET, to .sin.sin_family = AF_INET, fixes the problem. Signed-off-by: Gerhard Stenzel <gerhard.stenzel@de.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

A NULL pointer dereference is possible for the argument ring->buf_pool which is passed to xgene_enet_free_desc_ring(), as ring could be NULL. And now since NULL pointers are being checked for before the calls to xgene_enet_free_desc_ring(), might as well take advantage of them and not call the function if the argument would be NULL.

2014-08-22net: fec: ptp: avoid register access when ipg clock is disabledNimrod Andy3-15/+41
The current kernel hang on i.MX6SX with rootfs mount from MMC. The root cause is that ptp uses a periodic timer to access enet register even if ipg clock is disabled. FEC ptp driver start one period timer to read 1588 counter register in the ptp init function that is called after FEC driver is probed. To save power, after FEC probe finish, FEC driver disable all clocks including ipg clock that is needed for register access. i.MX5x, i.MX6q/dl/sl FEC register access don't cause system hang when ipg clock is disabled, just return zero value. But for i.MX6sx SOC, it cause system hang. To avoid the issue, we need to check ptp clock status before ptp timer count access.

There is a possible race condition when we unregister the PCI Driver and then flush/destroy the global "workq". This could lead to situations where there are tasks on the Work Queue with references to now deleted adapter data structures. Instead, have per-adapter Work Queues which were instantiated and torn down in init_one() and remove_one(), respectively. v2: Remove unnecessary call to flush_workqueue() before destroy_workqueue() Signed-off-by: Anish Bhatt <anish@chelsio.com> Signed-off-by: Casey Leedom <leedom@chelsio.com> Acked-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.

2014-08-22bnx2x: Revert UNDI flushing mechanismYuval Mintz1-75/+17
Commit 91ebb929b6f8 ("bnx2x: Add support for Multi-Function UNDI") [which was later supposedly fixed by de682941eef3 ("bnx2x: Fix UNDI driver unload")] introduced a bug in which in some [yet-to-be-determined] scenarios the alternative flushing mechanism which was to guarantee the Rx buffers are empty before resetting them during device probe will fail. If this happens, when device will be loaded once more a fatal attention will occur; Since this most likely happens in boot from SAN scenarios, the machine will fail to load. Notice this may occur not only in the 'Multi-Function' scenario but in the regular scenario as well, i.e., this introduced a regression in the driver's ability to perform boot from SAN. The patch reverts the mechanism and applies the old scheme to multi-function devices as well as to single-function devices.
