* netfilter: nft_quota: reset quota after dumpPablo Neira Ayuso2016-12-14
| | | | | | | | | | Dumping of netlink attributes may fail due to insufficient room in the skbuff, so let's reset consumed quota if we succeed to put netlink attributes into the skbuff.

* virtio-net: correctly enable multiqueueJason Wang2016-12-13
| | | | | | | | | | | | | | | | Commit 4490001029012539937ff02778fe6180613fa949 ("virtio-net: enable multiqueue by default") blindly set the affinity instead of queues during probe which can cause a mismatch of #queues between guest and host.

| * cris: No need to append -O2 and $(LINUXINCLUDE)Paul Bolle2016-12-08
| | | | | | | | | | | | | | | | | | | | | | | | The make variables asflags-y and ccflags-y are appended with -O2 and $(LINUXINCLUDE). But the build already picks up -O2 from the top Makefile and $(LINUXINCLUDE) from scripts/Makefile.lib. The net effect is that -O2 and the (long) list of include directories are used twice. This is harmless but pointless. So stop appending to these flags. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Jesper Nilsson <jespern@axis.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Kconfig currently controlling compilation of this code is: arch/cris/arch-v10/drivers/Kconfig:config ETRAX_SERIAL arch/cris/arch-v10/drivers/Kconfig: bool "Serial-port support" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. We don't replace module.h with init.h since the file already has that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If CONFIG_ETRAX_AXISFLASHMAP is not configured, the flash rescue image object file is empty. With recent versions of binutils, this results in the following build error. cris-linux-objcopy: error: the input file 'arch/cris/boot/rescue/rescue.o' has no sections This is seen, for example, when trying to build cris:allnoconfig with recently generated toolchains. Since it does not make sense to build a flash rescue image if there is no flash, only build it if CONFIG_ETRAX_AXISFLASHMAP is enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The of_platform_populate call in the openrisc arch code is now redundant as the DT core provides a default call. Openrisc has a NULL match table which means only top level nodes with compatible strings will have devices creates. The default version will also descend nodes in the match table such as "simple-bus" which should be fine as openrisc doesn't have any of these (though it is preferred that memory-mapped peripherals be grouped under a bus node(s)).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix signal handling for when signals are handled as the result of timers or exceptions, previous code assumed syscalls. This was noticeable with X crashing where it uses SIGALRM. This patch restores all regs before returning to userspace via _resume_userspace instead of via syscall return path. The rt_sigreturn syscall is more like a context switch than a function call; it entails a return from one context (the signal handler) to another (the process in question). For a context switch like this there are effectively no call-saved regs that remain constant across the transition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On OpenRISC, with its 8k pages, PAGE_SHIFT is defined to be 13. That makes the expression (1UL << (PAGE_SHIFT-2)) evaluate to 2048. The correct value for PTRS_PER_PGD should be 256. Correcting the PTRS_PER_PGD define unveiled a bug in map_ram(), where PTRS_PER_PGD was used when the intent was to iterate over a set of page table entries. This patch corrects that issue as well.

This is the per SoC hardware support. Contains a common platform device setup. Each of the SoC family members tends to have some minor local setup required to initialize the module. But all ColdFire family members use the same i2c hardware module. This i2c hardware module is the same as used in the Freescale iMX ARM based family of SoC devices. Steven's original patches were based on using a new and different i2c-coldfire.c driver. But this is not neccessary as we can use the existing Linux i2c-imx.c driver with no change required to it. And this patch is now based on using the existing i2c-imx driver. This patch only contains the ColdFire platform changes.

This approach is going to be slow though. Instead, use a percpu seqcount to fetch counters consistently, then subtract bytes and packets in case a reset was requested. The cpu that running over the reset code is guaranteed to own this stats exclusively, we have to turn counters into signed 64bit though so stats update on reset don't get wrong on underflow. This patch is based on original sketch from Eric Dumazet.

During autonegotiation, the PHYs will determine whether to enable pause frame support. Pause frames are a feature that is supported by the MAC. It is the MAC that generates the frames and that processes them. The PHY can only be configured to allow them to pass through. This commit also effectively reverts the recently applied c7a61319 ("net: phy: dp83848: Support ethernet pause frames"). So the new process is: 1) Unless the PHY driver overrides it, phylib sets the SUPPORTED_Pause and SUPPORTED_AsymPause bits in phydev->supported. This indicates that the PHY supports pause frames. 2) The MAC driver checks phydev->supported before it calls phy_start(). If (SUPPORTED_Pause | SUPPORTED_AsymPause) is set, then the MAC driver sets those bits in phydev->advertising, if it wants to enable pause frame support. 3) When the link state changes, the MAC driver checks phydev->pause and phydev->asym_pause, If the bits are set, then it enables the corresponding features in the MAC. The algorithm is: if (phydev->pause) The MAC should be programmed to receive and honor pause frames it receives, i.e. enable receive flow control. if (phydev->pause != phydev->asym_pause) The MAC should be programmed to transmit pause frames when needed, i.e. enable transmit flow control.

On the other hand the completion handler uses the reverse locking order by first taking the private lock and (in case that the tx queue had been stopped) then the xmit_lock. Improve the locking by removing the private lock and using only the xmit_lock for synchronization instead. Signed-off-by: Lino Sanfilippo <LinoSanfilippo@gmx.de> Signed-off-by: David S.
