The variable err was of the type u32. It was being compared with < 0, and being an unsigned variable the comparison would have been always false. Moreover, err was getting the return value from set_reset_mode() and xcan_set_bittiming(), and both are returning int.

2014-11-13smsc911x: power-up phydev before doing a software reset.Enric Balletbo i Serra1-0/+46
With commit be9dad1f9f26604fb ("net: phy: suspend phydev when going to HALTED"), the PHY device will be put in a low-power mode using BMCR_PDOWN if the the interface is set down. The smsc911x driver does a software_reset opening the device driver (ndo_open). In such case, the PHY must be powered-up before access to any register and before calling the software_reset function. Otherwise, as the PHY is powered down the software reset fails and the interface can not be enabled again. This patch fixes this scenario that is easy to reproduce setting down the network interface and setting up again. $ ifconfig eth0 down $ ifconfig eth0 up ifconfig: SIOCSIFFLAGS: Input/output error Signed-off-by: Enric Balletbo i Serra <eballetbo@iseebcn.com> Signed-off-by: David S.

2014-11-13net/smsc911x: Fix delays in the PHY enable/disable routinesAlexander Kochetkov1-5/+2
Increased delay in the smsc911x_phy_disable_energy_detect (from 1ms to 2ms). Dropped delays in the smsc911x_phy_enable_energy_detect (100ms and 1ms). The patch affect SMSC LAN generation 4 chips with integrated PHY (LAN9221). I saw problems with soft reset due to wrong udelay timings. After I fixed udelay, I measured the time needed to bring integrated PHY from power-down to operational mode (the time beetween clearing EDPWRDOWN bit and soft reset complete event). I got 1ms (measured using ktime_get). The value is equal to the current value (1ms) used in the smsc911x_phy_disable_energy_detect. It is near the upper bound and in order to avoid rare soft reset faults it is doubled (2ms). I don't know official timing for bringing up integrated PHY as specs doesn't clarify this (or may be I didn't found). It looks safe to drop delays before and after setting EDPWRDOWN bit (enable PHY power-down mode). I didn't saw any regressions with the patch.

2014-11-13net/smsc911x: Fix rare soft reset timeout issue due to PHY power-down modeAlexander Kochetkov1-6/+2
The patch affect SMSC LAN generation 4 chips with integrated PHY (LAN9221). It is possible that PHY could enter power-down mode (ENERGYON clear), between ENERGYON bit check in smsc911x_phy_disable_energy_detect and SRST bit set in smsc911x_soft_reset. This could happen, for example, if someone disconnect ethernet cable between the checks. The PHY in a power-down mode would prevent the MAC portion of chip to be software reseted. Initially found by code review, confirmed later using test case. This is low probability issue, and in order to reproduce it you have to run the script: while true; do ifconfig eth0 down ifconfig eth0 up || break done While the script is running you have to plug/unplug ethernet cable many times (using gpio controlled ethernet switch, for example) until get: [ 4516.477783] ADDRCONF(NETDEV_UP): eth0: link is not ready [ 4516.512207] smsc911x smsc911x.0: eth0: SMSC911x/921x identified at 0xce006000, IRQ: 336 [ 4516.524658] ADDRCONF(NETDEV_UP): eth0: link is not ready [ 4516.559082] smsc911x smsc911x.0: eth0: SMSC911x/921x identified at 0xce006000, IRQ: 336 [ 4516.571990] ADDRCONF(NETDEV_UP): eth0: link is not ready ifconfig: SIOCSIFFLAGS: Input/output error The patch was reviewed by Steve Glendinning and Microchip Team.

2014-11-13virtio_console: move early VQ enablementCornelia Huck1-2/+2
Commit f5866db6 (virtio_console: enable VQs early) tried to make sure that DRIVER_OK was set when virtio_console started using its virtqueues. Doing this in add_port(), however, means that we try to set DRIVER_OK again when when a port is dynamically added after the probe function is done. Let's move virtio_device_ready() to the probe function just before trying to use the virtqueues instead. This is fine as nothing can fail inbetween.

2014-11-12net: ptp: fix time stamp matching logic for VLAN packets.Richard Cochran2-3/+3
Commit ae5c6c6d "ptp: Classify ptp over ip over vlan packets" changed the code in two drivers that matches time stamps with PTP frames, with the goal of allowing VLAN tagged PTP packets to receive hardware time stamps. However, that commit failed to account for the VLAN header when parsing IPv4 packets. This patch fixes those two drivers to correctly match VLAN tagged IPv4/UDP PTP messages with their time stamps. This patch should also be applied to v3.17. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

In case an interface has been brought down before entering S3, and then brought up out of S3, all the initialization done during bcmgenet_probe() by bcmgenet_mii_init() calling bcmgenet_mii_config() is just lost since register contents are restored to their reset values. Re-apply this configuration anytime we call bcmgenet_open() to make sure our port multiplexer is properly configured to match the PHY interface. Since we are now calling bcmgenet_mii_config() everytime bcmgenet_open() is called, make sure we only print the message during initialization time not to pollute the console.

This fixes an issue where a network interface was suspended prior to a system suspend/resume cycle and would then be resumed as part of mdio_bus_resume(), since the GENET interface clocks would have been disabled, this basically resulted in bus errors to appear since we are invoking the GENET driver adjust_link() callback.

Based on the reference clock, which could be 25MHz or 40MHz, AR_RTC_DERIVED_CLK is programmed differently for AR9340 and AR9550. But, when a chip reset is done, processing the initvals sets the register back to the default value. Fix this by moving the code in ath9k_hw_init_pll() to ar9003_hw_override_ini(). Also, do this override for AR9531.

2014-11-12rt2x00: do not align payload on modern H/WStanislaw Gruszka1-38/+12
RT2800 and newer hardware require padding between header and payload if header length is not multiple of 4. For historical reasons we also align payload to to 4 bytes boundary, but such alignment is not needed on modern H/W. Patch fixes skb_under_panic problems reported from time to time: https://bugzilla.kernel.org/show_bug.cgi?id=84911 https://bugzilla.kernel.org/show_bug.cgi?id=72471 http://marc.info/?l=linux-wireless&m=139108549530402&w=2 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1087591 Panic happened because we eat 4 bytes of skb headroom on each (re)transmission when sending frame without the payload and the header length not being multiple of 4 (i.e. QoS header has 26 bytes). On such case because paylad_aling=2 is bigger than header_align=0 we increase header_align by 4 bytes. To prevent that we could change the check to: if (payload_length && payload_align > header_align) header_align += 4; but not aligning payload at all is more effective and alignment is not really needed by H/W (that has been tested on OpenWrt project for few years now).

2014-11-11net: ppp: Don't call bpf_prog_create() in ppp_lockTakashi Iwai1-20/+20
In ppp_ioctl(), bpf_prog_create() is called inside ppp_lock, which eventually calls vmalloc() and hits BUG_ON() in vmalloc.c. This patch works around the problem by moving the allocation outside the lock. The bug was revealed by the recent change in net/core/filter.c, as it allocates via vmalloc() instead of kmalloc() now.

Because we build kernels with drivers built in for many platforms, it's normal for the ibmpowernv driver to be loaded on systems that don't have the appropriate hardware. Currently the driver spams the log with: ibmpowernv ibmpowernv.0: Opal node 'sensors' not found ibmpowernv: Platfrom driver probe failed But there is no error, this machine is not a powernv and doesn't have the hardware. So change the sensors message to dev_dbg(), and only print an error about the probe failing if it's not ENODEV. Also fix the spelling of "Platfrom" and print the actual error value.
