Currently flowtable's GC work is initialized as deferrable, which means GC cannot work on time when system is idle. So the hardware offloaded flow may be deleted for timeout, since its used time is not timely updated. Resolve it by initializing the GC work as delayed work instead of deferrable.

Before this change, the mask is never included in the netlink message, so "conntrack -E expect" always prints 0.0.0.0. In older kernels the l3num callback struct was passed as argument, based on tuple->src.l3num. After the l3num indirection got removed, the call chain is based on m.src.l3num, but this value is 0xffff. Init l3num to the correct value.

When a new table value was assigned, it was followed by a write memory barrier. This ensured that all writes before this point would complete before any writes after this point. However, to determine whether the rules are unused, the sequence counter is read. To ensure that all writes have been done before these reads, a full memory barrier is needed, not just a write memory barrier. The same argument applies when incrementing the counter, before the rules are read. Changing to using smp_mb() instead of smp_wmb() fixes the kernel panic reported in cc00bcaa (which is still present), while still maintaining the same speed of replacing tables. The smb_mb() barriers potentially slow the packet path, however testing has shown no measurable change in performance on a 4-core MIPS64 platform.

This reverts commit cc00bcaa. This (and the preceding) patch basically re-implemented the RCU mechanisms of patch 78454473. That patch was replaced because of the performance problems that it created when replacing tables. Now, we have the same issue: the call to synchronize_rcu() makes replacing tables slower by as much as an order of magnitude. Prior to using RCU a script calling "iptables" approx. 200 times was taking 1.16s. With RCU this increased to 11.59s. Revert these patches and fix the issue in a different way. Signed-off-by:

When a QMI handle is initialized, an array of message handler structures is provided, defining how any received message should be handled based on its type and message ID. The QMI core code traverses this array when a message arrives and calls the function associated with the (type, msg_id) found in the array. The array is supposed to be terminated with an empty (all zero) entry though. Without it, an unsupported message will cause the QMI core code to go past the end of the array. Fix this bug, by properly terminating the message handler arrays provided when QMI handles are set up by the IPA driver. Fixes: 530f9216 ("soc: qcom: ipa: AP/modem communications") Reported-by:

Maciej moves storing of the rx_offset value to after the build_skb flag is set as this flag affects the offset value for ice, i40e, and ixgbe.

Igb needs a similar fix as commit 75aab4e1 ("i40e: avoid premature Rx buffer reuse") The page recycle code, incorrectly, relied on that a page fragment could not be freed inside xdp_do_redirect(). This assumption leads to that page fragments that are used by the stack/XDP redirect can be reused and overwritten. To avoid this, store the page count prior invoking xdp_do_redirect(). Longer explanation: Intel NICs have a recycle mechanism. The main idea is that a page is split into two parts. One part is owned by the driver, one part might be owned by someone else, such as the stack. t0: Page is allocated, and put on the Rx ring +--------------- used by NIC ->| upper buffer (rx_buffer) +--------------- | lower buffer +--------------- page count == USHRT_MAX rx_buffer->pagecnt_bias == USHRT_MAX t1: Buffer is received, and passed to the stack (e.g.) +--------------- | upper buff (skb) +--------------- used by NIC ->| lower buffer (rx_buffer) +--------------- page count == USHRT_MAX rx_buffer->pagecnt_bias == USHRT_MAX - 1 t2: Buffer is received, and redirected +--------------- | upper buff (skb) +--------------- used by NIC ->| lower buffer (rx_buffer) +--------------- Now, prior calling xdp_do_redirect(): page count == USHRT_MAX rx_buffer->pagecnt_bias == USHRT_MAX - 2 This means that buffer *cannot* be flipped/reused, because the skb is still using it. The problem arises when xdp_do_redirect() actually frees the segment. Then we get: page count == USHRT_MAX - 1 rx_buffer->pagecnt_bias == USHRT_MAX - 2 From a recycle perspective, the buffer can be flipped and reused, which means that the skb data area is passed to the Rx HW ring! To work around this, the page count is stored prior calling xdp_do_redirect(). Fixes: 9cbc948b ("igb: add XDP support") Signed-off-by:

ixgbe_rx_offset(), that is supposed to initialize the Rx buffer headroom, relies on __IXGBE_RX_BUILD_SKB_ENABLED flag. Currently, the callsite of mentioned function is placed incorrectly within ixgbe_setup_rx_resources() where Rx ring's build skb flag is not set yet. This causes the XDP_REDIRECT to be partially broken due to inability to create xdp_frame in the headroom space, as the headroom is 0.

Fix the wrong napi work done reporting in the xsk path of the ice driver. The code in the main Rx processing loop was written to assume that the buffer allocation code returns true if all allocations where successful and false if not. In contrast with all other Intel NIC xsk drivers, the ice_alloc_rx_bufs_zc() has the inverted logic messing up the work done reporting in the napi loop. This can be fixed either by inverting the return value from ice_alloc_rx_bufs_zc() in the function that uses this in an incorrect way, or by changing the return value of ice_alloc_rx_bufs_zc(). We chose the latter as it makes all the xsk allocation functions for Intel NICs behave in the same way. My guess is that it was this unexpected discrepancy that gave rise to this bug in the first place. Fixes: 5bb0c4b5 ("ice, xsk: Move Rx allocation out of while-loop") Reported-by:

htb_init may fail to do the offload if it's not supported or if a runtime error happens when allocating direct qdiscs. In those cases TC_HTB_CREATE command is not sent to the driver, however, htb_destroy gets called anyway and attempts to send TC_HTB_DESTROY. It shouldn't happen, because the driver didn't receive TC_HTB_CREATE, and also because the driver may not support ndo_setup_tc at all, while q->offload is true, and htb_destroy mistakenly thinks the offload is supported. Trying to call ndo_setup_tc in the latter case will lead to a NULL pointer dereference. This commit fixes the issues with htb_destroy by deferring assignment of q->offload until after the TC_HTB_CREATE command. The necessary cleanup of the offload entities is already done in htb_init.

htb_select_queue assumes it's always the offload mode, and it ends up in calling ndo_setup_tc without any checks. It may lead to a NULL pointer dereference if ndo_setup_tc is not implemented, or to an error returned from the driver, which will prevent attaching qdiscs to HTB classes in the non-offload mode.

Tony Nguyen says: ==================== Intel Wired LAN Driver Updates 2021-03-11 This series contains updates to igc and e1000e drivers. Sasha adds locking to reset task to prevent race condition for igc. Muhammad fixes reporting of supported pause frame as well as advertised pause frame for Tx/Rx off for igc. Andre fixes timestamp retrieval from the wrong timer for igc. Vitaly adds locking to reset task to prevent race condition for e1000e. Dinghao Liu adds a missed check to return on error in e1000_set_d0_lplu_state_82571. ==================== Signed-off-by: -

Introduce the new function tw_prot_init (inspired by req_prot_init) to simplify "proto_register" function. tw_prot_cleanup will take care of a partially initialized timewait_sock_ops. Signed-off-by:

There is one e1e_wphy() call in e1000_set_d0_lplu_state_82571 that we have caught its return value but lack further handling. Check and terminate the execution flow just like other e1e_wphy() in this function. Fixes: bc7f75fa ("[E1000E]: New pci-express e1000 driver (currently for ICH9 devices only)") Signed-off-by:

A possible race condition was found in e1000_reset_task, after discovering a similar issue in igb driver via commit 024a8168 ("igb: reinit_locked() should be called with rtnl_lock"). Added rtnl_lock() and rtnl_unlock() to avoid this. Fixes: bc7f75fa ("[E1000E]: New pci-express e1000 driver (currently for ICH9 devices only)") Suggested-by:

The comment describing the timestamps layout in the packet buffer is wrong and the code is actually retrieving the timestamp in Timer 1 reference instead of Timer 0. This hasn't been a big issue so far because hardware is configured to report both timestamps using Timer 0 (see IGC_SRRCTL register configuration in igc_ptp_enable_rx_timestamp() helper). This patch fixes the comment and the code so we retrieve the timestamp in Timer 0 reference as expected. This patch also takes the opportunity to get rid of the hw.mac.type check since it is not required. Fixes: 81b05520 ("igc: Add support for RX timestamping") Signed-off-by:
