[ Upstream commit f2c3037811381f9149243828c7eb9a1631df9f9c ] CQP completion statistics is read lockesly in irdma_wait_event and irdma_check_cqp_progress while it can be updated in the completion thread irdma_sc_ccq_get_cqe_info on another CPU as KCSAN reports. Make completion statistics an atomic variable to reflect coherent updates to it. This will also avoid load/store tearing logic bug potentially possible by compiler optimizations.

[ Upstream commit d64b1ee12a168030fbb3e0aebf7bce49e9a07589 ] This code is trying to ensure that only the flags specified in the list are allowed. The problem is that ucmd->rx_hash_fields_mask is a u64 and the flags are an enum which is treated as a u32 in this context. That means the test doesn't check whether the highest 32 bits are zero.

2023-08-03igc: Fix Kernel Panic during ndo_tx_timeout callbackMuhammad Husaini Zulkifli
[ Upstream commit d4a7ce642100765119a872d4aba1bf63e3a22c8a ] The Xeon validation group has been carrying out some loaded tests with various HW configurations, and they have seen some transmit queue time out happening during the test. This will cause the reset adapter function to be called by igc_tx_timeout(). Similar race conditions may arise when the interface is being brought down and up in igc_reinit_locked(), an interrupt being generated, and igc_clean_tx_irq() being called to complete the TX. When the igc_tx_timeout() function is invoked, this patch will turn off all TX ring HW queues during igc_down() process. TX ring HW queues will be activated again during the igc_configure_tx_ring() process when performing the igc_up() procedure later. This patch also moved existing igc_disable_tx_ring_hw() to avoid using forward declaration.

2023-08-03platform/x86: msi-laptop: Fix rfkill out-of-sync on MSI Wind U100Maxim Mikityanskiy
[ Upstream commit ad084a6d99bc182bf109c190c808e2ea073ec57b ] Only the HW rfkill state is toggled on laptops with quirks->ec_read_only (so far only MSI Wind U90/U100). There are, however, a few issues with the implementation: 1. The initial HW state is always unblocked, regardless of the actual state on boot, because msi_init_rfkill only sets the SW state, regardless of ec_read_only. 2. The initial SW state corresponds to the actual state on boot, but it can't be changed afterwards, because set_device_state returns -EOPNOTSUPP. It confuses the userspace, making Wi-Fi and/or Bluetooth unusable if it was blocked on boot, and breaking the airplane mode if the rfkill was unblocked on boot. Address the above issues by properly initializing the HW state on ec_read_only laptops and by allowing the userspace to toggle the SW state. Don't set the SW state ourselves and let the userspace fully control it. Toggling the SW state is a no-op, however, it allows the userspace to properly toggle the airplane mode. The actual SW radio disablement is handled by the corresponding rtl818x_pci and btusb drivers that have their own rfkills. Tested on MSI Wind U100 Plus, BIOS ver 1.0G, EC ver 130.

2023-08-03net: stmmac: Apply redundant write work around on 4.xx tooVincent Whitchurch
[ Upstream commit 284779dbf4e98753458708783af8c35630674a21 ] commit a3a57bf07de23fe1ff779e0fdf710aa581c3ff73 ("net: stmmac: work around sporadic tx issue on link-up") worked around a problem with TX sometimes not working after a link-up by avoiding a redundant write to MAC_CTRL_REG (aka GMAC_CONFIG), since the IP appeared to have problems with handling multiple writes to that register in some cases. That commit however only added the work around to dwmac_lib.c (apart from the common code in stmmac_main.c), but my systems with version 4.21a of the IP exhibit the same problem, so add the work around to dwmac4_lib.c too.

[ Upstream commit 4e62c99d71e56817c934caa2a709a775c8cee078 ] As of today, hash extraction support is enabled for all the silicons. Because of which we are facing initialization issues when the silicon does not support hash extraction. During creation of the hardware parsing table for IPv6 address, we need to consider if hash extraction is enabled then extract only 32 bit, otherwise 128 bit needs to be extracted. This patch fixes the issue and configures the hardware parser based on the availability of the feature.

2023-08-03team: reset team's flags when down link is P2P deviceHangbin Liu
[ Upstream commit fa532bee17d15acf8bba4bc8e2062b7a093ba801 ] When adding a point to point downlink to team device, we neglected to reset the team's flags, which were still using flags like BROADCAST and MULTICAST. Consequently, this would initiate ARP/DAD for P2P downlink interfaces, such as when adding a GRE device to team device. Fix this by remove multicast/broadcast flags and add p2p and noarp flags. After removing the none ethernet interface and adding an ethernet interface to team, we need to reset team interface flags. Unlike bonding interface, team do not need restore IFF_MASTER, IFF_SLAVE flags.

[ Upstream commit a3336056504d780590ac6d6ac94fbba829994594 ] Fix ethtool FDIR logic to not use memory after its release. In the ice_ethtool_fdir.c file there are 2 spots where code can refer to pointers which may be missing. In the ice_cfg_fdir_xtrct_seq() function seg may be freed but even then may be still used by memcpy(&tun_seg[1], seg, sizeof(*seg)). In the ice_add_fdir_ethtool() function struct ice_fdir_fltr *input may first fail to be added via ice_fdir_update_list_entry() but then may be deleted by ice_fdir_update_list_entry. Terminate in both cases when the returned value of the previous operation is other than 0, free memory and don't use it anymore.

2023-08-03vxlan: calculate correct header length for GPEJiri Benc
[ Upstream commit 94d166c5318c6edd1e079df8552233443e909c33 ] VXLAN-GPE does not add an extra inner Ethernet header. Take that into account when calculating header length. This causes problems in skb_tunnel_check_pmtu, where incorrect PMTU is cached. In the collect_md mode (which is the only mode that VXLAN-GPE supports), there's no magic auto-setting of the tunnel interface MTU. It can't be, since the destination and thus the underlying interface may be different for each packet. So, the administrator is responsible for setting the correct tunnel interface MTU. Apparently, the administrators are capable enough to calculate that the maximum MTU for VXLAN-GPE is (their_lower_MTU - 36). They set the tunnel interface MTU to 1464. If you run a TCP stream over such interface, it's then segmented according to the MTU 1464, i.e. producing 1514 bytes frames. Which is okay, this still fits the lower MTU. However, skb_tunnel_check_pmtu (called from vxlan_xmit_one) uses 50 as the header size and thus incorrectly calculates the frame size to be 1528. This leads to ICMP too big message being generated (locally), PMTU of 1450 to be cached and the TCP stream to be resegmented. The fix is to use the correct actual header size, especially for skb_tunnel_check_pmtu calculation.

2023-08-03iavf: check for removal state before IAVF_FLAG_PF_COMMS_FAILEDJacob Keller
[ Upstream commit 91896c8acce23d33ed078cffd46a9534b1f82be5 ] In iavf_adminq_task(), if the function can't acquire the adapter->crit_lock, it checks if the driver is removing. If so, it simply exits without re-enabling the interrupt. This is done to ensure that the task stops processing as soon as possible once the driver is being removed. However, if the IAVF_FLAG_PF_COMMS_FAILED is set, the function checks this before attempting to acquire the lock. In this case, the function exits early and re-enables the interrupt. This will happen even if the driver is already removing. Avoid this, by moving the check to after the adapter->crit_lock is acquired. This way, if the driver is removing, we will not re-enable the interrupt.
