* net/libertas: make SPI interface big endian awareSebastian Andrzej Siewior2009-06-03
| | | | | | | | | | | | | The comment (which I remove) says that the translation is done SPI routines. IMHO this can't work because the SPI driver does not know whether the incomming bytes are part of the registers/bytes which need to be flipped or part of packet data which has to remain untouched. While adding le helpers I also removed spu_write_u32() which has no users.

* fsl_pq_mido: Set the first UCC as the mii management interface masterHaiying Wang2009-06-03
| | | | | | | | | | | | | | Current code makes the UCC whose register range includes the current mdio register to be the MII managemnt interface master of the QE. If there is more than one mdio bus for QE, the UCC of the last mdio bus will be the MII management interface master which will make the primary mdio bus working unproperly, e.g. can not get the right clock. Normally the primary mdio bus is the first UEC's mdio bus. This patch allows the first UCC to be the MII management interface master of the multiple UCC mdio buses.

| | | | | | | | | | | | | | This patch provides support for the next generation Intel desktop and mobile gigabit ethernet LOM adapters. These adapters are the follow-on parts to the LOMs tied to the prior ICH chipsets and are comprised of a MAC in the PCH chipset and an external PHY (82577 for mobile and 82578 for desktop versions). New features consist of PHY wakeup to save power by completely turning off the MAC while in Sx state, and 4K jumbo frames.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | panic when we use cls_cgroup This patch fixes a bug which unconfigured struct tcf_proto keeps chaining in tc_ctl_tfilter(), and avoids kernel panic in cls_cgroup_classify() when we use cls_cgroup. When we execute 'tc filter add', tcf_proto is allocated, initialized by classifier's init(), and chained. After it's chained, tc_ctl_tfilter() calls classifier's change(). When classifier's change() fails, tc_ctl_tfilter() does not free and keeps tcf_proto. In addition, cls_cgroup is initialized in change() not in init(). It accesses unconfigured struct tcf_proto which is chained before change(), then hits Oops.

| * e1000: add missing length check to e1000 receive routineNeil Horman2009-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch to fix bad length checking in e1000. E1000 by default does two things: 1) Spans rx descriptors for packets that don't fit into 1 skb on recieve 2) Strips the crc from a frame by subtracting 4 bytes from the length prior to doing an skb_put Since the e1000 driver isn't written to support receiving packets that span multiple rx buffers, it checks the End of Packet bit of every frame, and discards it if its not set. This places us in a situation where, if we have a spanning packet, the first part is discarded, but the second part is not (since it is the end of packet, and it passes the EOP bit test). If the second part of the frame is small (4 bytes or less), we subtract 4 from it to remove its crc, underflow the length, and wind up in skb_over_panic, when we try to skb_put a huge number of bytes into the skb. This amounts to a remote DOS attack through careful selection of frame size in relation to interface MTU. The fix for this is already in the e1000e driver, as well as the e1000 sourceforge driver, but no one ever pushed it to e1000. This is lifted straight from e1000e, and prevents small frames from causing the underflow described above Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Tested-by: Andy Gospodarek <andy@greyhouse.net> Signed-off-by: David S.

| * forcedeth: add phy_power_down parameter, leave phy powered up by default (v2)Ed Swierk2009-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a phy_power_down parameter to forcedeth: set to 1 to power down the phy and disable the link when an interface goes down; set to 0 to always leave the phy powered up. The phy power state persists across reboots; Windows, some BIOSes, and older versions of Linux don't bother to power up the phy again, forcing users to remove all power to get the interface working (see http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy powered on is the safest default behavior. Users accustomed to seeing the link state reflect the interface state and/or wanting to minimize power consumption can set phy_power_down=1 if compatibility with other OSes is not an issue.

Thus the conntrack entry is destroyed but the destination retransmits data until timeout. The same technique, i.e. sending properly crafted RST segments, can easily be used to bypass connlimit/connbytes based restrictions (the sample script written by Robert can be found in the netfilter mailing list archives). The patch below adds a new flag and new field to struct ip_ct_tcp_state so that checking RST segments can be made more strict and thus TCP conntrack can catch the invalid ones: the RST segment is accepted only if its sequence number higher than or equal to the highest ack we seen from the other direction. (The last_ack field cannot be reused because it is used to catch resent packets.) Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>

But atl2.c seems like it doesn't want the modinfo data from atlx.h, as it defines its own. Running modinfo on atl2.ko, we get conflicting information: $ /sbin/modinfo drivers/net/atlx/atl2.ko | egrep "version|description|author" version: 2.2.3 description: Atheros Fast Ethernet Network Driver author: Atheros Corporation <xiong.huang@atheros.com>, Chris Snook <csnook@redhat.com> version: 2.1.3 author: Xiong Huang <xiong.huang@atheros.com>, Chris Snook <csnook@redhat.com>, Jay Cliburn <jcliburn@gmail.com> Move the modinfo data out of atlx.h and into atl1.c to eliminate the confusion: $ /sbin/modinfo drivers/net/atlx/atl1.ko | egrep "version|description|author" version: 2.1.3 author: Xiong Huang <xiong.huang@atheros.com>, Chris Snook <csnook@redhat.com>, Jay Cliburn <jcliburn@gmail.com> description: Atheros L1 Gigabit Ethernet Driver $ /sbin/modinfo drivers/net/atlx/atl2.ko | egrep "version|description|author" version: 2.2.3 description: Atheros Fast Ethernet Network Driver author: Atheros Corporation <xiong.huang@atheros.com>, Chris Snook <csnook@redhat.com> Reported-by: Scott Scriven <scott.scriven@hp.com> Signed-off-by: Alex Chiang <achiang@hp.com> Acked-by: Jay Cliburn <jcliburn@gmail.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gianfar interrupt handler uses IEVENT_ERR_MASK to check and handle errors. Babbling RX error (IEVENT_BABR) should be included in IEVENT_ERROR_MASK. Otherwise if BABR is raised, it never gets handled nor cleared, and an interrupt storm results. This has been observed to happen on sending a burst of ethernet frames to a gianfar based board. Signed-off-by: Xiaotian Feng <xiaotian.feng@windriver.com> Signed-off-by: David S.

| | * | wimax/i2400m: usb: fix device reset on autosuspend while not yet idleInaky Perez-Gonzalez2009-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the i2400m is connected to a network, the host interface (USB) cannot be suspended. For that to happen, the device has to have negotiated with the basestation to put the link on IDLE state. If the host tries to put the device in standby while it is connected but not idle, the device resets, as the driver should not do that. To avoid triggering that, when the USB susbsytem requires the driver to autosuspend the device, the driver checks if the device is not yet idle. If it is not, the request is rejected (will be retried again later on after the autosuspend timeout). At some point the device will enter idle and the request will succeed (unless of course, there is network traffic, but at that point, there is no idle neither in the link or the host interface).

| * | | r8169: avoid losing MSI interruptsDavid Dillow2009-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 8169 chip only generates MSI interrupts when all enabled event sources are quiescent and one or more sources transition to active. If not all of the active events are acknowledged, or a new event becomes active while the existing ones are cleared in the handler, we will not see a new interrupt. The current interrupt handler masks off the Rx and Tx events once the NAPI handler has been scheduled, which opens a race window in which we can get another Rx or Tx event and never ACK'ing it, stopping all activity until the link is reset (ifconfig down/up). Fix this by always ACK'ing all event sources, and loop in the handler until we have all sources quiescent.
