* net: mediatek: Explicitly include pinctrl headersThierry Reding2018-02-051-0/+1
| | | | | | | | | | | | | The Mediatek ethernet driver fails to build after commit 23c35f48f5fb ("pinctrl: remove include file from <linux/device.h>") because it relies on the pinctrl/consumer.h and pinctrl/devinfo.h being pulled in by the device.h header implicitly. Include these headers explicitly to avoid the build failure.

| * net: qlge: use memmove instead of skb_copy_to_linear_dataArnd Bergmann2018-02-021-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gcc-8 points out that the skb_copy_to_linear_data() argument points to the skb itself, which makes it run into a problem with overlapping memcpy arguments: In file included from include/linux/ip.h:20, from drivers/net/ethernet/qlogic/qlge/qlge_main.c:26: drivers/net/ethernet/qlogic/qlge/qlge_main.c: In function 'ql_realign_skb': include/linux/skbuff.h:3378:2: error: 'memcpy' source argument is the same as destination [-Werror=restrict] memcpy(skb->data, from, len); It's unclear to me what the best solution is, maybe it ought to use a different helper that adjusts the skb data in a safe way.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | passing the strlen() of the source string as the destination length is pointless, and gcc-8 now warns about it: drivers/net/ethernet/qlogic/qed/qed_debug.c: In function 'qed_grc_dump': include/linux/string.h:253: error: 'strncpy' specified bound depends on the length of the source argument [-Werror=stringop-overflow=] This changes qed_grc_dump_big_ram() to instead uses the length of the destination buffer, and use strscpy() to guarantee nul-termination.

| * net: cxgb4: avoid memcpy beyond end of source bufferArnd Bergmann2018-02-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building with link-time-optimizations revealed that the cxgb4 driver does a fixed-size memcpy() from a variable-length constant string into the network interface name: In function 'memcpy', inlined from 'cfg_queues_uld.constprop' at drivers/net/ethernet/chelsio/cxgb4/cxgb4_uld.c:335:2, inlined from 'cxgb4_register_uld.constprop' at drivers/net/ethernet/chelsio/cxgb4/cxgb4_uld.c:719:9: include/linux/string.h:350:3: error: call to '__read_overflow2' declared with attribute error: detected read beyond size of object passed as 2nd parameter __read_overflow2(); ^ I can see two equally workable solutions: either we use a strncpy() instead of the memcpy() to stop at the end of the input, or we make the source buffer fixed length as well. This implements the latter. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S. Miller <davem@davemloft.net>
| * r8152: set rx mode early when linking onHayes Wang2018-02-021-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Set rx mode before calling netif_wake_queue() when linking on to avoid the device missing the receiving packets. The transmission may start after calling netif_wake_queue(), and the packets of resopnse may reach before calling rtl8152_set_rx_mode() which let the device could receive packets.

Then user tries to unload that module by provided module name and fails. This happens because ethtool reads value of DRV_NAME macro, while module name is defined at the driver's Makefile. This patch is to correct Cavium CN88xx Thunder NIC driver names (DRV_NAME macro) 'thunder-nicvf' to 'nicvf' and 'thunder-nic' to 'nicpf', sync bgx and xcv driver names accordingly to their module names.

This is important for protecting against replay attacks. Since validation of fragmented frames is more complex, the CCMP header for those is preserved. To keep the counter in sync, the first fragment is verified by both mt76 and mac80211, and all other fragments only by mac80211.

Once it's done it's possible to get more accurate rssi/signal values over whole frequency band at a given temperature. The RSSI/signal accuracy reported by calibrated RF cards improves from 6 to up to 2dB. This could be interesting for application which require good signal accuracy like roaming or mesh protocols.

Then we halt the device CPU, load FW image and resume the device CPU. There are some boot loader versions which perform redundant memory accesses even when idle. Halting the device CPU while boot loader access memory can cause the device memory controller to get stuck, the FW will fail to load and the network interface will not come up. For such boot loaders implement a workaround where we freeze the boot loader before halting the device CPU, so it will not perform any memory accesses.

In SW reset flow, the host driver sets the clock frequency to 40MHz. In order to allow reading from the OTP, the host driver should configure the OTP HW vectors with the values that fits this clock frequency.
