commit 985af6f7 upstream. Need the following workaround in the driver for interoperability with the older Intel SSD drives and any other SATA drive that may exhibit the same behavior. This is a corner case where SCU speed is limited to either 3G or 1.5G and the drive has a period of DC idle when it switches speed during SATA speed negotiation. Workaround :change PHYTOV[31:24] from 0x36 to 0x3B. Signed-off-by:

commit 0a96e975 upstream. PCI and SR-IOV Fixes - Call pci_save_state after the pci_restore_state completes. - After calling pci_enable_pcie_error_reporting() and checking the return value for logging messages from rc, reset rc to 0 to it will not later be interpreted for error. - Read PCI config space SR-IOV capability to get the number of VFs supported. - Check for the PF's supported number of VFs before invoking PCI enable sriov API call and log error message that user requested number of VFs is beyond the PF capability if such request is passed in. - Added check for Physical function with Virtual Functions attached. If so, first disable all the VFs before proceeding to device reset. Signed-off-by:

commit 7851fe2c upstream. Adapter Interface fixes and changes - Modify the macro field from lpfc_init_vpi_vpi to lpfc_init_vfi_vpi - Add the new CQE_CODE_RECEIVE_V1 CQE Code, add code in the driver to handle the new Code the same as the CQE_CODE_RECEIVE code except that there are two new checks for this code that will cause the driver to use the new V1 macros for rq_id and fcf_id. - Fix a bug in lpfc_prep_seq() where the size out of the first CQE was ONLY being used, even though multiple dmabufs make up the sequence, each have their own CQE with potentially different sizes. - Fix bug in lpfc_bsg_ct_unsol_event() where the ulpContext and ulpWord[3] fields of the XMIT_SEQUENCE64_CX IOCB were being calculated incorrectly. - Do physical to logical translation before indexing into the active XRI array. - Populate physical vpi in the iocb data structure. - Put the current accumulated total in each IOCB in the chain as we are walking thru then. The last IOCB in the chain should have the total length of the sequence. Signed-off-by:

commit 6b07d30a upstream. This patch changes the call of tpm_transmit by supplying the size of the userspace buffer instead of TPM_BUFSIZE. This got assigned CVE-2011-1161. [The first hunk didn't make sense given one could expect way less data than TPM_BUFSIZE, so added tpm_transmit boundary check over bufsiz instead The last parameter of tpm_transmit() reflects the amount of data expected from the device, and not the buffer size being supplied to it. It isn't ideal to parse it directly, so we just set it to the maximum the input buffer can handle and let the userspace API to do such job.] Signed-off-by:

commit a7f4d00a upstream. As the Amiga Zorro II address space is limited to 8.5 MiB and Zorro devices can contain only one BAR, several Amiga Zorro II expansion boards (mainly graphics cards) contain multiple Zorro devices: a small one for the control registers and one (or more) for the graphics memory. The conversion of cirrusfb to the new driver framework introduced a regression: the driver contains a zorro_driver for the first Zorro device, and uses the (old) zorro_find_device() call to find the second Zorro device. However, as the Zorro core calls device_register() as soon as a Zorro device is identified, it may not have identified the second Zorro device belonging to the same physical Zorro expansion card. Hence cirrusfb could no longer find the second part of the Picasso II graphics card, causing a NULL pointer dereference. Defer the registration of Zorro devices with the driver framework until all Zorro devices have been identified to fix this. Note that the alternative solution (modifying cirrusfb to register a zorro_driver for all Zorro devices belonging to a graphics card, instead of only for the first one, and adding a synchronization mechanism to defer initialization until all have been found), is not an option, as on some cards one device may be optional (e.g. the second bank of 2 MiB of graphics memory on the Picasso IV in Zorro II mode).

[ Upstream commit bcf66bf5 ] When asyncronous crypto algorithms are used, there might be many packets that passed the xfrm replay check, but the replay advance function is not called yet for these packets. So the replay check function would accept a replay of all of these packets. Also the system might crash if there are more packets in async processing than the size of the anti replay window, because the replay advance function would try to update the replay window beyond the bounds. This pach adds a second replay check after resuming from the async processing to fix these issues. Signed-off-by:

[ Upstream commit c5114cd5 ] It's after all necessary to do reset headers here. The reason is we cannot depend that it gets reseted in __netif_receive_skb once skb is reinjected. For incoming vlanids without vlan_dev, vlan_do_receive() returns false with skb != NULL and __netif_reveive_skb continues, skb is not reinjected.

[ Upstream commit 3557619f ] commit 07bd8df5 (sch_sfq: fix peek() implementation) changed sfq to use generic peek helper. This makes HFSC complain about a non-work-conserving child qdisc, if prio with sfq child is used within hfsc: hfsc peeks into prio qdisc, which will then peek into sfq. returned skb is stashed in sch->gso_skb. Next, hfsc tries to dequeue from prio, but prio will call sfq dequeue directly, which may return NULL instead of previously peeked-at skb. Have prio call qdisc_dequeue_peeked, so sfq->dequeue() is not called in this case. Cc: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by:

[ Upstream commit 797fd391 ] TCP in some cases uses different global (raw) socket to send RST and ACK. The transparent flag is not set there. Currently, it is a problem for rerouting after the previous change. Fix it by simplifying the checks in ip_route_me_harder and use FLOWI_FLAG_ANYSRC even for sockets. It looks safe because the initial routing allowed this source address to be used and now we just have to make sure the packet is rerouted. As a side effect this also allows rerouting for normal raw sockets that use spoofed source addresses which was not possible even before we eliminated the ip_route_input call. Signed-off-by:

[ Upstream commit 97a80410 ] As rt_iif represents input device even for packets coming from loopback with output route, it is not an unique key specific to input routes. Now rt_route_iif has such role, it was fl.iif in 2.6.38, so better to change the checks at some places to save CPU cycles and to restore 2.6.38 semantics. compare_keys: - input routes: only rt_route_iif matters, rt_iif is same - output routes: only rt_oif matters, rt_iif is not used for matching in __ip_route_output_key - now we are back to 2.6.38 state ip_route_input_common: - matching rt_route_iif implies input route - compared to 2.6.38 we eliminated one rth->fl.oif check because it was not needed even for 2.6.38 compare_hash_inputs: Only the change here is not an optimization, it has effect only for output routes. I assume I'm restoring the original intention to ignore oif, it was using fl.iif - now we are back to 2.6.38 state Signed-off-by:

It allocates new exchangeID (RX_ID) always from non-offloaded pool (Non-offload EMA) Fix: Enhanced fcoe_oem_match routine to look at F_CTL flags and if it is exchange responder and command type is WRITEDATA, then function returns TRUE instead of FALSE. This function is used to determine which pool to use (offload pool of exchange is used only if this function returns TRUE). Technical Notes: N/A Signed-off-by:

commit 48058481 upstream. Problem: Existing RPORT state machine continues witg FLOGI/PLOGI process only after it receices beacon from other end. Once claiming stage is over (either clain notify or clain repose), beacon is sent and state machine enters into operational mode where it initiates the rlogin process (FLOGI/PLOGI) to the peer but before this rlogin is initiated, exitsing implementation checks if it received beacon from other end, it beacon is not received yet, rlogin process is not initiated. Other end initiates FLOGI but peer end keeps on rejecting FLOGI, hence after 3 retries other end deletes associated rport, then sends a beacon. Once the beacon is received, peer end now initiates rlogin to the peer end but since associated rport is deleted FLOGI is neither accepted nor the reject response send out because rport is deleted. Hence unable to proceed withg FLOGI/PLOGI process and fails to establish VN2VN connection. Fix: VN2VN spec is not standard yet but based on exitsing collateral on T11, it appears that, both end shall send beacon and enter into 'operational mode' without explictly waiting for beacon from other end. Fix is to allow the RPORT login process as long as respective RPORT is created (as part of claim notification / claim response) even though state of RPORT is INIT. Means don't wait for beacon from peer end, if peer end initiates FLOGI (means peer end exist and responding). Notes: This patch is preparing the FCoE stack for target wrt offload. This is generic patch and harmless even if applied on storage initiator because 'else if' condition of function 'fcoe_oem_found' shall evaluate to TRUE only for targets.

commit 36c35416 upstream. Fix a misusage of the struct usb_cdc_notification to pass arguments to the usb_control_msg function. The usb_control_msg function expects host endian arguments but usb_cdc_notification stores these values as little endian. Now usb_control_msg is directly invoked with host endian values.
