| * ath10k: check chip id from the soc register during probeKalle Valo2013-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ath10k doesn't support qca988x hw1.0 boards anymore. Unfortunately the PCI id is the same in hw1.0 and hw2.0 so ath10k tries to use hw1.0 boards anyway. But without hw1.0 workarounds in place ath10k just crashes horribly. To avoid using hw1.0 boards at all add a chip id detection and fail the probe if hw1.0 is detected: [ 5265.786408] ath10k: ERROR: qca988x hw1.0 is not supported [ 5265.786497] ath10k: Unsupported chip id 0x043200ff [ 5265.786574] ath10k: could not register driver core (-95) [ 5265.793191] ath10k_pci: probe of 0000:02:00.0 failed with error -95 Also add a warning if there's an unknown chip id but continue the boot process normally anyway.

| * ath10k: add support for HTT 3.0Michal Kazior2013-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | New firmware comes with new HTT protocol version. In 3.0 the separate mgmt tx command has been removed. All traffic is to be pushed through data tx (tx_frm) command with a twist - FW seems to not be able (yet?) to access tx fragment table so for manamgement frames frame pointer is passed directly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The mgmt_rx event structure has been expanded. Since the structure header is expanded the payload (i.e. mgmt frame) is shifted by a few bytes. This needs to be taken into account in order to support both old and new firmware. This introduces a fw_features to keep track of any FW-related ABI/behaviour changes.

Integrate SCTP better into the ipv6 output path so that these problems are fixed and such issues don't get missed in the future either.

Fix from Michal Kubecek. 18) VF reset recovery not being done correctly in qlcnic driver, from Manish Chopra. 19) Fix inverted test in ATM nicstar driver, from Andy Shevchenko. 20) Missing workqueue destroy in cxgb4 error handling, from Wei Yang. 21) Internal switch not initialized properly in bgmac driver, from Rafał Miłecki. 22) Netlink messages report wrong local and remote addresses in IPv6 tunneling, from Ding Zhi. 23) ICMP redirects should not generate socket errors in DCCP and SCTP. We're still working out how this should be handled for RAW and UDP sockets. From Daniel Borkmann and Duan Jiong. 24) We've had several bugs wherein the network namespace's loopback device gets accessed after it is free'd, NULL it out so that we can catch these problems more readily. From Eric W Biederman. 25) Fix regression in TCP RTO calculations, from Neal Cardwell. 26) Fix too early free of xen-netback network device when VIFs still exist.

| * | netconsole: fix a deadlock with rtnl and netconsole's mutexNikolay Aleksandrov2013-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug was introduced by commit 7a163bfb7ce50895bbe67300ea610d31b9c09230 ("netconsole: avoid a crash with multiple sysfs writers"). In store_enabled() we have the following sequence: acquire nt->mutex then rtnl, but in the netconsole netdev notifier we have rtnl then nt->mutex effectively leading to a deadlock. The NULL pointer dereference that the above commit tries to fix is actually due to another bug in netpoll_cleanup(). This is fixed by dropping the mutex from the netdev notifier as it's already protected by rtnl. Signed-off-by: Nikolay Aleksandrov <nikolay@redhat.com> Signed-off-by: David S.

Note this part of the patch: + if (skge_rx_setup(skge, e, nskb, skge->rx_buf_size) < 0) { + dev_kfree_skb(nskb); + goto resubmit; + } + pci_unmap_single(skge->hw->pdev, dma_unmap_addr(e, mapaddr), dma_unmap_len(e, maplen), PCI_DMA_FROMDEVICE); skb = e->skb; prefetch(skb->data); - skge_rx_setup(skge, e, nskb, skge->rx_buf_size); The function skge_rx_setup modifies e->skb to point to the new skb. Thus, after this change, the new buffer, not the old, is returned to the networking stack. This bug is present in kernels 3.11, 3.11.1 and 3.12-rc1. The patch should be queued for 3.11-stable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If local fragmentation is allowed, then ip_select_ident() and ip_select_ident_more() need to generate unique IDs to ensure correct defragmentation on the peer. For example, if IPsec (tunnel mode) has to encrypt large skbs that have local_df bit set, then all IP fragments that belonged to different ESP datagrams would have used the same identificator. If one of these IP fragments would get lost or reordered, then peer could possibly stitch together wrong IP fragments that did not belong to the same datagram. This would lead to a packet loss or data corruption. Signed-off-by: Ansis Atteka <aatteka@nicira.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * | xen-netback: Don't destroy the netdev until the vif is shut downPaul Durrant2013-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this patch, if a frontend cycles through states Closing and Closed (which Windows frontends need to do) then the netdev will be destroyed and requires re-invocation of hotplug scripts to restore state before the frontend can move to Connected. Thus when udev is not in use the backend gets stuck in InitWait. With this patch, the netdev is left alone whilst the backend is still online and is only de-registered and freed just prior to destroying the vif (which is also nicely symmetrical with the netdev allocation and registration being done during probe) so no re-invocation of hotplug scripts is required.

| * | cnic: Fix crash in cnic_bnx2x_service_kcq()Michael Chan2013-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 104a43edb264321a4d41850e98153b4fa8a9ef42 cnic: Use CHIP_NUM macros from bnx2x.h changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE is supported or not. There is another place in cnic that is still using the old method to determine if FCoE is supported or not. The 2 methods may not yield the same result after the network interface is brought down and up. This will cause the crash as cnic_bnx2x_service_kcq() will access the uninitialized cp->kcq2. The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which uses the bnx2x NO_FCOE() macro. As a follow-up, we can clean up the code to remove the old method as it is no longer needed.

| * | bnx2x, cnic, bnx2i, bnx2fc: Fix bnx2i and bnx2fc regressions.Michael Chan2013-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit b9871bcfd211d316adee317608dab44c58d6ea2d bnx2x: VF RSS support - PF side changed the configuration of the doorbell HW and it broke iSCSI and FCoE. We fix this by making compatible changes to the doorbell address in bnx2i and bnx2fc. For the userspace driver, we need to pass a modified CID so that the existing userspace driver will calculate the correct doorbell address and continue to work.

| * | vxlan: Avoid creating fdb entry with NULL destinationSridhar Samudrala2013-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit afbd8bae9c798c5cdbe4439d3a50536b5438247c vxlan: add implicit fdb entry for default destination creates an implicit fdb entry for default destination. This results in an invalid fdb entry if default destination is not specified. For ex: ip link add vxlan1 type vxlan id 100 creates the following fdb entry 00:00:00:00:00:00 dev vxlan1 dst 0.0.0.0 self permanent This patch fixes this issue by creating an fdb entry only if a valid default destination is specified.

| * | net loopback: Set loopback_dev to NULL when freedEric W. Biederman2013-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has recently turned up that we have a number of long standing bugs in the network stack cleanup code with use of the loopback device after it has been freed that have not turned up because in most cases the storage allocated to the loopback device is not reused, when those accesses happen. Set looback_dev to NULL to trigger oopses instead of silent data corrupt when we hit this class of bug. Signed-off-by: "Eric W.

Minimal support for the 40G configuration. 2. Disable the incomplete PTP/hardware timestamping support. 3. Reset MAC stats properly after a firmware upgrade. 4. Re-check the datapath firmware capabilities after the controller is reset. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
