This patch reworks a previous workaround (commit 7d3cabbc) for an issue in hardware where noise on the interconnect between the MAC and PHY could be generated by a lower power mode (K1) at 1000Mbps resulting in bad packets. Disable K1 while at 1000 Mbps but keep it enabled for 10/100Mbps and when the cable is disconnected. The original version of this workaround was found to be incomplete.

On PCH-based (82577/82578) and some ICH8-based parts (82566) there is an issue with the hardware automatically configuring the PHY with contents from the EEPROM after the PHY is reset, so do the configuration by the driver instead. This was already similarly done for some 82566 parts in e1000_phy_hw_reset_ich8lan() but needs to be done after other resets, so move the PHY configuration code to its own function and call after all PHY resets.

A change in how PHYs are electrically isolated caused all PHYs to be isolated followed by reverting that isolation for the selected PHY. Unfortunately, isolating the selected PHY for even a short period of time can result in DHCP negotiation taking more than 10 seconds on certain embedded configurations delaying boot time as reported by Bernhard Kaindl. This patch reverts the change to how PHYs are isolated yet still works around the issue for 82552 needing the selected PHY's BMCR register to be written after the unused PHYs are isolated. This code is moved below the setting of nic->phy ID in order to do the 82552-specific workaround.

Currently PACKET_TX_RING forces certain amount of every frame to remain unused. This probably originates from an early version of the PACKET_TX_RING patch that in fact used the extra space when the (since removed) CONFIG_PACKET_MMAP_ZERO_COPY option was enabled. The current code does not make any use of this extra space. This patch removes the extra space reservation and lets userspace make use of the full frame size.

Augment raw_send_hdrinc to correct for incorrect ip header length values A series of oopses was reported to me recently. Apparently when using AF_RAW sockets to send data to peers that were reachable via ipsec encapsulation, people could panic or BUG halt their systems. I've tracked the problem down to user space sending an invalid ip header over an AF_RAW socket with IP_HDRINCL set to 1. Basically what happens is that userspace sends down an ip frame that includes only the header (no data), but sets the ip header ihl value to a large number, one that is larger than the total amount of data passed to the sendmsg call. In raw_send_hdrincl, we allocate an skb based on the size of the data in the msghdr that was passed in, but assume the data is all valid. Later during ipsec encapsulation, xfrm4_tranport_output moves the entire frame back in the skbuff to provide headroom for the ipsec headers. During this operation, the skb->transport_header is repointed to a spot computed by skb->network_header + the ip header length (ihl). Since so little data was passed in relative to the value of ihl provided by the raw socket, we point transport header to an unknown location, resulting in various crashes. This fix for this is pretty straightforward, simply validate the value of of iph->ihl when sending over a raw socket. If (iph->ihl*4U) > user data buffer size, drop the frame and return -EINVAL. I just confirmed this fixes the reported crashes. Signed-off-by: NNeil Horman <nhorman@tuxdriver.com> Acked-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S.

In mii monitor mode, bond_check_dev_link() calls the the ioctl handler of slave devices. It stores the ndo_do_ioctl function pointer to a static (!) ioctl variable and later uses it to call the handler with the IOCTL macro. If another thread executes bond_check_dev_link() at the same time (even with a different bond, which none of the locks prevent), a race condition occurs. If the two racing slaves have different drivers, this may result in one driver's ioctl handler being called with a pointer to a net_device controlled with a different driver, resulting in unpredictable breakage. Unless I am overlooking something, the "static" must be a copy'n'paste error (?). Signed-off-by: NJiri Bohac <jbohac@suse.cz> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

When hostapd injects a frame, e.g. an authentication or association response, mac80211 looks for a suitable access point virtual interface to associate the frame with based on its source address. This makes it possible e.g. to correctly assign sequence numbers to the frames. A small typo in the ethernet address comparison statement caused a failure to find a suitable ap interface. Sequence numbers on such frames where therefore left unassigned causing some clients (especially windows-based 11b/g clients) to reject them and fail to authenticate or associate with the access point. This patch fixes the typo in the address comparison statement.

Recent commit "mac80211: fix logic error ibss merge bssid check" fixed joining of ibss cell when static bssid is provided. In this case ifibss->bssid is set before the cell is joined and comparing that address to a bss should thus always succeed. Unfortunately this change broke the other case of joining a ibss cell without providing a static bssid where the value of ifibss->bssid is not set before the cell is joined. Since ifibss->bssid may be set before or after joining the cell we do not learn anything by comparing it to a known bss. Remove this check.

This patch fixes both the original bug in #14181 and the bug introduced by the previous patch. It must be stated, however, that if there is a BCM4306/3 with an rfkill switch (not yet proven), then the driver will need an unload/reload cycle to turn the device back on.

Be more careful about the state of pointers during tear-down. The "pppoe_dev" field can only be looked at safely while holding socket locks. This subsequently allows for the flush_lock to be killed. We depend on the PPPOX_CONNECTED state to tell us that that those fields are valid, so whoever clears that state (pppox_unbind_sock()) is responsible for the dev_put() call. We also have to ensure that we delete_item() on all sockets before they are cleaned up. The need for these changes has been exposed by scenarios wherein namespace bindings of ethernet devices change while there are ongoing PPPoE sessions, which resulted in oopses due to unusual socket connection termination paths, exposing these issues.

PCH-based parts (82577/82578) and some ICH8-based parts (82566) need to hold the swflag (sw/fw/hw hardware semaphore) over consecutive PHY accesses in order to perform sw-driven PHY configuration during initialization to workaround known hardware issues (see follow-on patch). This patch provides new PHY read/write functions (and function pointers) that will allow accessing the PHY registers assuming the swflag has already been acquired. The actual PHY register access code has moved into helper functions that are called with a flag indicating whether or not the swflag has already been acquired and acquires/releases it if not. The functions called from within the updated PHY access functions had to be updated to assume the swflag was already acquired, and other functions that called those functions were also updated to acquire/release the swflag.

The 8110SC rev d chip on our board shows a regression which the 8110SB chip did not have. When inbound traffic is overflowing the receive descriptor queue, "holes" in the ring buffer may occur which lead to a hangup until the buffer is filled again. The packets are than completely processed, but the ring remains porous and no packets are processed until the next overflow. Setting the interface down and up can fix the problem temporary from userspace. For some reason we don't know, this behaviour is not occuring if the RxVlan bit for hardware VLAN untagging is set. There is another "Work around for AMD plateform" in the current code which checks the VLAN status word in receive descriptors, but does never come to effect when hardware VLAN support is enabled. We assume that this is a bug in the chip. The following patch fixes the problem. Without the patch we could reproduce the hang within minutes (given other devices also generating lots of interrupts), without we couldn't reproduce within a few days of long term testing. This version contains minor style adjustments and is sent with mutt which will hopefully not destroy the formatting again.

At this point (ri_tasklet()), RTNL or dev_base_lock are not held, we must use dev_get_by_index() instead of __dev_get_by_index() Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
