Tom Lendacky says: ==================== amd-xgbe: AMD XGBE driver fixes 2014-09-05 The following series of patches includes fixes to the driver. - Proper access to 64 bit management counter registers - Enable all management counter registers to generate an interrupt when the counter threshold is reached This patch series is based on net. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Lendacky, Thomas authored
As the management counters reach a threshold they will generate an interrupt so the value can be saved and the counter reset. The current code does not enable this interrupt on all counters. This can result in inaccurate statistics. Update the code to enable all the counters to generate an interrupt when its threshold is exceeded. Signed-off-by:

Lendacky, Thomas authored
Even if the management counters are configured to be 32 bit register values, the [rt]xoctetcount_gb and [rt]xoctetcount_g counters are always 64 bit counter registers. Since they are not being treated as 64 bit values, these statistics are being reported incorrectly (ifconfig, ethtool, etc.). Update the routines used to read the registers to access the "hi" register (an offset of 4 from the "lo" register) to create a 64 bit value for these 64 bit counters. Signed-off-by:

This patch does not affect the 10/100 GRETH MAC. Before all GBit GRETH TX descriptor ring cleaning was done in start_xmit(), when descriptor list became full it activated TX interrupt to start the NAPI rx poll function to do TX ring cleaning. With this patch the TX descriptor ring is always cleaned from the NAPI rx poll function, triggered via TX or RX interrupt. Otherwise we could end up in TX frames being sent but not reported to the stack being sent. On the 10/100 GRETH this is not an issue since the SKB is copied&aligned into private buffers so that the SKB can be freed directly on start_xmit() Signed-off-by:

It seems on 32 bit kernels page_address() can reutrn a NULL value in some circumstances, and the pci_map_single api isn't prepared to handle that (on this system it results in a bogus pointer deference in nommu_map_page. The fix is pretty easy, if we convert the 3c59x driver to use the more convieient skb_frag_dma_map api we don't need to find the virtual address of the page at all, and page gets mapped to the hardware properly. Verified to fix the problem as described by the reporter. Applies to the net tree Change Notes: v2) Converted PCI_DMA_TODEVICE to DMA_TO_DEVICE. Thanks Dave! v3) Actually Run git commit after making changes to v2 :) Signed-off-by:

There is no reason to take a refcnt before deleting the peer address route. It's done some lines below for the local prefix route because inet6_ifa_finish_destroy() will release it at the end.

The timestamping API has separate bits for generating and reporting timestamps. A software timestamp should only be reported for a packet when the packet has the relevant generation flag (SKBTX_..) set and the socket has reporting bit SOF_TIMESTAMPING_SOFTWARE set. The second check was accidentally removed. Reinstitute the original behavior. Tested: Without this patch, Documentation/networking/txtimestamp reports timestamps regardless of whether SOF_TIMESTAMPING_SOFTWARE is set. After the patch, it only reports them when the flag is set.

Pablo Neira Ayuso says: ==================== pull request: Netfilter/IPVS fixes for net The following patchset contains seven Netfilter fixes for your net tree, they are: 1) Make the NAT infrastructure independent of x_tables, some users are already starting to test nf_tables with NAT without enabling x_tables. Without this patch for Kconfig, there's a superfluous dependency between NAT and x_tables. 2) Allow to use 0 in the cgroup match, the kernel rejects with -EINVAL with no good reason. From Daniel Borkmann. 3) Select CONFIG_NF_NAT from the nf_tables NAT expression, this also resolves another NAT dependency with x_tables. 4) Use HAVE_JUMP_LABEL instead of CONFIG_JUMP_LABEL in the Netfilter hook code as elsewhere in the kernel to resolve toolchain problems, from Zhouyi Zhou. 5) Use iptunnel_handle_offloads() to set up tunnel encapsulation depending on the offload capabilities, reported by Alex Gartrell patch from Julian Anastasov. 6) Fix wrong family when registering the ip_vs_local_reply6() hook, also from Julian. 7) Select the NF_LOG_* symbols from NETFILTER_XT_TARGET_LOG. Rafał Miłecki reported that when jumping from 3.16 to 3.17-rc, his log target is not selected anymore due to changes in the previous development cycle to accomodate the full logging support for nf_tables. ==================== Signed-off-by: -

Some hosts can be both little and big endian. In certain scenarios a big endian kernel can kexec a little endian kernel. This patch fixes this case from both ends: 1) Return endianity to original values on shutdown (in case little endian kernel boots after we shutdown). 2) Do not rely on HW reset values when loading driver in little endian kernel but configure them explicitly (in case previous kernel was big endian and did not reset the HW).

When qeth device is queried for ethtool data, hardware operation is performed to extract the necessary information from the card. If the card is not online at the moment (e.g. it is undergoing recovery), this operation produces undesired effects like temporarily freezing the system. This patch prevents execution of the hardware query operation when the card is not online. In such case, ioctl() operation returns error with errno ENODEV. Reviewed-by:

The patch fixes race conditions between PCI error recovery callbacks and potential ifup/ifdown. First, if ifup (tg3_open) is called between tg3_io_error_detected() and tg3_io_resume() then tp->timer is armed twice before expiry. Once during tg3_open() and again during tg3_io_resume(). This results in BUG at kernel/time/timer.c:945. Second, if ifdown (tg3_close) is called between tg3_io_error_detected() and tg3_io_resume() then tg3_napi_disable() is called twice without a tg3_napi_enable between. Once during tg3_io_error_detected() and again during tg3_close(). The tg3_io_resume() then hangs on rtnl_lock(). v2: Added logging messages per Prashant's request Cc: Prashant Sreedharan <prashant@broadcom.com> Cc: Michael Chan <mchan@broadcom.com> Signed-off-by:

Fixes few register access for both T4 and T5. PCIE_CORE_UTL_SYSTEM_BUS_AGENT_STATUS & PCIE_CORE_UTL_PCI_EXPRESS_PORT_STATUS is T4 only register don't let T5 access them. For T5 MA_PARITY_ERROR_STATUS2 is additionally read. MPS_TRC_RSS_CONTROL is T4 only register, for T5 use MPS_T5_TRC_RSS_CONTROL. Signed-off-by:

We previously assumed that a Port's Capabilities and Advertised Capabilities would never change from Port Initialization time. This is no longer true when we can have 10Gb/s and 1Gb/s SFP+ Transceiver Modules randomly swapped. Signed-off-by:

For new GMACs it is possible to turn-on/off the COE. In the current driver, when disabled the Rx-checksum via ethtool, the tool reported that csum was disabled but the HW continued to set the IPC. Indeed this is because the fix_features allows this. So the patch fixes this problem by adding the set_features. Signed-off-by:

When configuring Tx flow control the Rx queue count was used instead of the Tx queue count for looping through the Tx hardware queues. Fix the code to use the Tx queue count. Signed-off-by:

The debugfs support for the xpcs registers did not properly use the specified mmd (xpcs_mmd entry) which resulted in the default mmd value always being used. Update the debugfs support to generate the proper mmd register value. Signed-off-by:

The fifo size reported by the hardware is not correct. Add support to limit the reported size to what is actually present. Also, fix the argument types used in the fifo size calculation function. Signed-off-by:
