These are used like: set_bit(WORK_LINK_UP, &priv->work_pending); The problem is that set_bit() takes the actual bit number and not a mask so static checkers get upset. It doesn't affect run time because we do it consistently, but we may as well clean it up. Fixes: 6010ce07 ('rndis_wlan: do link-down state change in worker thread') Signed-off-by:

In d8a2c51c ('ath9k_htc: Use atomic operations for op_flags') we changed things like this: - if (priv->op_flags & OP_TSF_RESET) { + if (test_bit(OP_TSF_RESET, &priv->op_flags)) { The problem is that test_bit() takes a bit number and not a mask. It means that when we do: set_bit(OP_TSF_RESET, &priv->op_flags); Then it sets the (1 << 6) bit instead of the 6 bit so we are setting a bit which is past the end of the unsigned long.

gcc-5.0 gained a new warning in the fwsignal portion of the brcmfmac driver: drivers/net/wireless/brcm80211/brcmfmac/fwsignal.c: In function 'brcmf_fws_txs_process': drivers/net/wireless/brcm80211/brcmfmac/fwsignal.c:1478:8: warning: 'skb' may be used uninitialized in this function [-Wmaybe-uninitialized] This is a false positive, and marking the brcmf_fws_hanger_poppkt function as 'static inline' makes the warning go away. I have checked the object file output and while a little code gets moved around, the size of the binary remains identical. Signed-off-by:

Return type of wait_for_completion_timeout is unsigned long not int. An appropriately named unsigned long is added, and the assignments as well as error checking fixed up. API conformance testing for completions with coccinelle spatches are being used to locate API usage inconsistencies: ./drivers/net/wireless/ath/carl9170/usb.c:675 int return assigned to unsigned long Patch was compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m, CONFIG_CARL9170=m Patch is against 4.1-rc3 (localversion-next is -next-20150512) Signed-off-by:

This patch adds support for FW memory read/write operations via debugfs. This is useful during debugging FW issues. Examples: For reading FW memory location: echo r 0x01ac > /sys/kernel/debug/mwifiex/mlan0/memrw cat /sys/kernel/debug/mwifiex/mlan0/memrw For writing FW memory location: echo w 0x01ac 0x55aa > /sys/kernel/debug/mwifiex/mlan0/memrw Signed-off-by:

During usage of the new Bluetooth driver for Realtek devices, it was found that BT scans were inhibited for the RTL8723BE when wireless was active. The exact cause of this interference is not known yet, but a satisfactory work around has been found that does not seem to have any visible side effects. Signed-off-by:

The PCI cache line size value was being compared against decimal values prefixed with 0x. Fixed the literals to use the correct hex values. This has not been tested due to lack of hardware. However, the value in `cline` is PCI cache line size, which is the CPU's cache line size. It is less likely for cache line sizes to be 22 or 50, and more likely for them to be 16 or 32. Also, as far as I understand, cache line size is used for things like aligning DMA requests with CPU cache line, which improve performance but wouldn't break anything if the value doesn't match. In this case, we will fall through to the default case which leaves `reg` unchanged. Signed-off-by:

This patch implements sendpage support for AF_UNIX SOCK_STREAM sockets. This is also required for a complete splice implementation. The implementation is a bit tricky because we append to already existing skbs and so have to hold unix_sk->readlock to protect the reading side from either advancing UNIXCB.consumed or freeing the skb at the socket receive tail.

Or Gerlitz says: ==================== mlx4: Enable single ported VFs over IB ports This series further enhances the support for mlx4 single ported VFs introduced in 3.15 to work over IB ports too. Just as quick reminder, the ConnectX3 device family exposes one PCI device which serves both ports. This can be non-optimal under virtualization schemes where the admin would like the VF to expose one interface to the VM, etc. Since all the VF interaction with the firmware passes through the PF driver, we can emulate to the VF they have one port, and further create a set of the VFs which act on port1 of the device and another set which acts on port2. ==================== Signed-off-by: -

-
Or Gerlitz authored
Some VF drivers flow set the schedule queue in the QP context but without setting none of OPTPAR_SCHED_QUEUE or OPTPAR_PRIMARY_ADDR_PATH. To allow for such non-modified drivers to function as single ported IB VFs, we must adjust the schedule queue port whenever being set, e.g as currently done for single ported Eth VFs. Signed-off-by:

Or Gerlitz authored
As part of enabling single ported VFs over IB ports we need to handle some of the flows for generting EQ events for VFs which don't come into play under Eth ports. This mainly includes port management events derived from changes of the phyiscal port (lid change, client re-register, down/up, etc), VF pkey table changes and VF guid changes initiated by the IB driver. (1) make sure that events are generated only for VFs sitting on the relevant physical port (under the ALL_SLAVES flow). (2) before generating the event, convert from physical (one or two) to VF port (always equals one). Signed-off-by: -
Or Gerlitz authored
When multiplexling a MAD sent from VF, we should convert the port used by the guest to send the packet to the actual physical port which will be used to transmit the packet, before building the relevant address-handle (AH). This is needed under VPI for single ported VFs, since the code that builds the AH (mlx4_ib_query_ah()) makes decisions based on the input port. If we use the port number provided by the guest, it might have different protocol vs. the one this packat has to go from, and hence the result could be wrong. So far, the conversion was done after the AH was built and it worked for single ported Eth VFs which were not enabled under VPI. When adding support for single ported IB VFs and VPI, we hit that.

Single port VFs always provide port = 1 (even if the actual physical port used is port 2). As such, we need to convert the port provided by the VF to the physical port before calling into the firmware. It turns out that the Linux mlx4 VF RoCE driver maintains a copy of the GID table and hence this change became critical only for single ported IB VFs, but it could be needed for other RoCE VF drivers too.

Jesper Dangaard Brouer says: ==================== pktgen: cleanups and introducing new samples/pktgen scripts v3: - Aborted v2 send due it was not generating diff stat (this is a bug in stg-mail, if not in the root directory) v2: address nitpicks from Cong Wang - Remove useless cat's, but keep them for old pgset() - Comment on: Due to pgctrl, cannot use exit code $? from grep - Use arithmetic compare in pktgen_sample03_burst_single_flow.sh This patchset is focused on making pktgen easier to use and better documented. It contains a number of documentation updates and minor changes to pktgen. The major contribution is introduction of common helper function for sample scripts. Instead of the old pgset() function, three new shell functions for configuring the different components of pktgen are introduced: pg_ctrl(), pg_thread() and pg_set(). The new functions correspond to pktgens different components. * pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl) * pg_thread() control the kernel threads and binding to devices * pg_set() control setup of individual devices Helpers also provide consistent parameter parsing across the sample scripts. Usage example: ./pktgen_sample01_simple.sh -i eth41 -m 00:12:C0:02:AC:5A -d 192.168.41.2 Usage: ./pktgen_sample01_simple.sh [-vx] -i ethX -i : ($DEV) output interface/device (required) -s : ($PKT_SIZE) packet size -d : ($DEST_IP) destination IP -m : ($DST_MAC) destination MAC-addr -t : ($THREADS) threads to start -c : ($SKB_CLONE) SKB clones send before alloc new SKB -b : ($BURST) HW level bursting of SKBs -v : ($VERBOSE) verbose -x : ($DEBUG) debug These scripts are borrowed from: https://github.com/netoptimizer/network-testing/tree/master/pktgen ==================== Signed-off-by:
