In commit 2a04ae8a ("hv_netvsc: remove locking in netvsc_send()"), the locking for MSD (Multi-Send Data) field was removed. This could cause a race condition between RNDIS control messages and data packets processing, because these two types of traffic are not synchronized. This patch fixes this issue by sending control messages out directly without reading MSD field. Signed-off-by:

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2015-12-13 This series contains updates to fm10k only. Jacob updates the driver to use ether_addr_copy() instead of copying byte-by-byte in a for loop. Fixed up CamelCase variable names and coding style issues. Cleaned up namespace pollution of fm10k_iov_msg_data_pf(). Cleaned up, by making it consistent, the use of VLAN and VLAN ID instead of vlan or vid. Lastly, update the driver to initialize XPS so that we can take advantage of the kernel feature. Alex Duyck fixed up the driver to free the resources associated with the MSI-X vector table if the q_vector allocation failed. Then fixed the driver to check for msix_entries to be NULL and freed the IRQ if the mailbox API returned an error on trying to connect. Bruce cleans up whitespace and namespace pollution issues in the driver. Also updates the driver to use the BIT() macro instead of bit-shifting coding. ==================== Signed-off-by:

This patch addresses two issues. First is the fact that the fm10k_mbx_free_irq was assuming msix_entries was valid and that will not always be the case. As such we need to add a check for if it is NULL. Second is the fact that we weren't freeing the IRQ if the mailbox API returned an error on trying to connect. Signed-off-by:

Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2015-12-12 This series contains updates to e1000, e1000e and igb. Joern Engel fixes up the e1000 driver to reduce scheduler latencies by making the eeprom read/write functions scheduler friendly by using a mutex lock instead of a spin lock. Todd adds code for igb to initialize the 88E1543 PHY properly. Then fixed igb to use the correct i210 register for EEMNGCTL, since the i210 has two EEPROM access registers (EEARBC and EEMNGCTL). Dmitry Vyukov provides a fix for e1000 to resolve a data race found with KernelThreadSanitizer (KTSAN), where no memory barriers were being used when buffers get recycled, so the recycled buffers can be corrupted. So use smp_store_release() to update tx_ring->next_to_clean and smp_load_acquire() to read tx_ring->next_to_clean to properly hand off buffers from e1000_clean_tx_irq() to e1000_xmit_frame(). Jarod Wilson fixes igb so that we do not try to unmap a NULL hw_addr. Then cleaned up array_rd32() so that it uses igb_rd32() the same as rd32() and use io_addr() in more places so that we do not have to call E1000_REMOVED(). Janusz Wolak cleans up the e1000 driver by correcting warnings produced by checkpatch.pl for the driver. Jean Sacren provides several patches with general cleanups for e1000 and e1000e, which include code comment fix-ups and cleanup of local variables not needed. Dmitry Fleytman fixes a possible division by zero in the receive interrupt handler for e1000e when working without adaptive interrupt moderation, which is typically disabled on jumbo MTUs. Raanan increases the timeout of the polling bit due to timing changes to the ME firmware on a platform, so increase the timeout to 300ms. Added initial support for i219-LM, which is a LOM that will be available on systems with the Lewisburg Platform Controller HUB (PCH) chipset. Jan Beulich fixes a NULL dereference in igb, due to the adapter->vf _data being NULL while adapter->vfs_allocated_count is non-zero. ==================== Signed-off-by: -

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2015-12-12 This series contains updates to i40e and i40evf only. Jesse fixes some trivial static analyzer warnings where BIT() can be used instead of BIT_ULL(). Mitch fixes the virtual channel interface which was using incorrect semantics to remove MAC addresses and would leave incorrect filters active when using VLANs. Also fixes an issue that when VF's are created, the MAC address defaults to all zeros, indicating to the VF driver that it should use a random MAC address. However, the PF driver was incorrectly adding this zero MAC to the filter table, so check for a good address before adding the default filter. Adds a check to make sure that the Tx and Rx rings actually exist before dereferencing them to free resources. Re-classifies several messages which are really for debugging purposes, especially since the driver can fully recover from any of these. Fixed up the VF version strings to match the PF driver. Anjali adds a virtchnl offload to support the expanded version of TCP/UDP PCTYPES for RSS. Shannon fixes i40e to clean the whole MAC filter list when resetting after an intermediate add or delete push to the firmware. v2: added blank line after variable declaration in patch 9 based on feedback from Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> ==================== Signed-off-by: -
Jan Beulich authored
The combined effect of commits 6423fc34 ("igb: do not re-init SR-IOV during probe") and ceee3450 ("igb: make sure SR-IOV init uses the right number of queues") causes VFs no longer getting set up, leading to NULL pointer dereferences due to the adapter's ->vf_data being NULL while ->vfs_allocated_count is non-zero. The first commit not only neglected the side effect of igb_sriov_reinit() that the second commit tried to account for, but also that of setting IGB_FLAG_HAS_MSIX, without which igb_enable_sriov() is effectively a no-op. Calling igb_{,re}set_interrupt_capability() as done here seems to address this, but I'm not sure whether this is better than sinply reverting the other two commits. Signed-off-by:

The checking logic needed some clean-up work, so we rewrite it by checking for break first. With that change in place, we can even move the second check for goto statement outside of the loop. As this is merely a cleanup, no functional change is involved. The questionable 'tmp != 0xFF' is intentionally left alone. Mark Rustad and Alexander Duyck contributed to this patch.

Well, now that hw_addr is NULL, the attempt to call pci_iounmap is obviously not going to go well. As suggested by Mark Rustad, do something similar to what ixgbe does, and save a copy of hw_addr as adapter->io_addr, so we can still call pci_iounmap on it on teardown. Additionally, for consistency, make the pci_iomap call assignment directly to io_addr, so map and unmap match. Signed-off-by:

e1000_clean_tx_irq cleans buffers and sets tx_ring->next_to_clean, then e1000_xmit_frame reuses the cleaned buffers. But there are no memory barriers when buffers gets recycled, so the recycled buffers can be corrupted. Use smp_store_release to update tx_ring->next_to_clean and smp_load_acquire to read tx_ring->next_to_clean to properly hand off buffers from e1000_clean_tx_irq to e1000_xmit_frame.
