2009-11-17net: fix mdio section mismatch warningStephen Rothwell1-1/+1
This fixes the following warning: WARNING: drivers/net/phy/built-in.o(.devexit.text+0x70): Section mismatch in reference from the function .mdio_gpio_bus_destroy() to the function .devinit.text:.mdio_gpio_bus_deinit() The function __devexit .mdio_gpio_bus_destroy() references a function __devinit .mdio_gpio_bus_deinit(). This is often seen when error handling in the exit function uses functionality in the init path.

2009-11-16ppp: fix BUG on non-linear SKB (multilink receive)Ben McKeegan1-2/+9
PPP does not correctly call pskb_may_pull() on all necessary receive paths before reading the PPP protocol, thus causing PPP to report seemingly random 'unsupported protocols' and eventually trigger BUG_ON(skb->len < skb->data_len) in skb_pull_rcsum() when receiving multilink protocol in non-linear skbs. ppp_receive_nonmp_frame() does not call pskb_may_pull() before reading the protocol number. For the non-mp receive path this is not a problem, as this check is done in ppp_receive_frame(). For the mp receive path, ppp_mp_reconstruct() usually copies the data into a new linear skb. However, in the case where the frame is made up of a single mp fragment, the mp header is pulled and the existing skb used. This skb was then passed to ppp_receive_nonmp_frame() without checking if the encapsulated protocol header could safely be read.

Commit b7802c5c1ea ("Input: psmouse - use boolean type") caused the synaptics_hardware variable to be completely useless, as it is constantly set to 'true' throughout the whole psmouse_extensions(). This was caused by the following hunk in the commit in question - int synaptics_hardware = 0; + bool synaptics_hardware = true; which is wrong and causes driver to issue extra reset when falling back to bare PS/2 protocol.

2009-11-13r8169: Fix receive buffer length when MTU is between 1515 and 1536Raimonds Cicans1-2/+2
In r8169 driver MTU is used to calculate receive buffer size. Receive buffer size is used to configure hardware incoming packet filter. For jumbo frames: Receive buffer size = Max frame size = MTU + 14 (ethernet header) + 4 (vlan header) + 4 (ethernet checksum) = MTU + 22 Bug: driver for all MTU up to 1536 use receive buffer size 1536 As you can see from formula, this mean all IP packets > 1536 - 22 (for vlan tagged, 1536 - 18 for not tagged) are dropped by hardware filter. Example: host_good> ifconfig eth0 mtu 1536 host_r8169> ifconfig eth0 mtu 1536 host_good> ping host_r8169 Ok host_good> ping -s 1500 host_r8169 Fail host_good> ifconfig eth0 mtu 7000 host_r8169> ifconfig eth0 mtu 7000 host_good> ping -s 1500 host_r8169 Ok Bonus: got rid of magic number 8 Signed-off-by: Raimonds Cicans <[email protected]> Signed-off-by: David S.

2009-11-13can: Fix driver Kconfig structureOliver Hartkopp4-55/+64
In 2.6.32-rc the new EMS USB CAN driver was contributed and added the Kconfig entry right behind an entry of the same *vendor*. This teared the SJA1000 based driver selection into pieces. This fix cleans up the 2.6.32-rc Kconfig files for the CAN drivers and moves the SJA1000 and USB Kconfig portions into the belonging directories. As there are many new CAN drivers in the queue getting this cleanup into 2.6.32-rc would massively reduce the problems for the upcoming drivers.

2009-11-13md/raid5: Allow dirty-degraded arrays to be assembled when only party is ↵NeilBrown1-4/+75
degraded. Normally is it not safe to allow a raid5 that is both dirty and degraded to be assembled without explicit request from that admin, as it can cause hidden data corruption. This is because 'dirty' means that the parity cannot be trusted, and 'degraded' means that the parity needs to be used. However, if the device that is missing contains only parity, then there is no issue and assembly can continue. This particularly applies when a RAID5 is being converted to a RAID6 and there is an unclean shutdown while the conversion is happening. So check for whether the degraded space only contains parity, and in that case, allow the assembly. Signed-off-by: NeilBrown <[email protected]>
2009-11-13Don't unconditionally set in_sync on newly added device in raid5_reshapeNeilBrown1-2/+4
When a reshape finds that it can add spare devices into the array, those devices might already be 'in_sync' if they are beyond the old size of the array, or they might not if they are within the array. The first case happens when we change an N-drive RAID5 to an N+1-drive RAID5. The second happens when we convert an N-drive RAID5 to an N+1-drive RAID6. So set the flag more carefully. Also, ->recovery_offset is only meaningful when the flag is clear, so only set it in that case. This change needs the preceding two to ensure that the non-in_sync device doesn't get evicted from the array when it is stopped, in the case where v0.90 metadata is used.

2009-11-13md: allow v0.91 metadata to record devices as being active but not in-sync.NeilBrown1-6/+25
This is a combination that didn't really make sense before. However when a reshape is converting e.g. raid5 -> raid6, the extra device is not fully in-sync, but is certainly active and contains important data. So allow that start to be meaningful and in particular get the 'recovery_offset' value (which is needed for any non-in-sync active device) from the reshape_position.
