[PATCH openEuler-22.03-LTS-SP1 5/6] bnxt_en: Implement .set_port / .unset_port UDP tunnel callbacks
by Baogen Shang 14 Mar '24

14 Mar '24

From: Somnath Kotur <somnath.kotur(a)broadcom.com> stable inclusion from stable-v5.10.184 commit 3f6dfff5fe416bda6469cf235eaa9c54fee2a0bc category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8L4MY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 1eb4ef12591348c440ac9d6efcf7521e73cf2b10 ] As per the new udp tunnel framework, drivers which need to know the details of a port entry (i.e. port type) when it gets deleted should use the .set_port / .unset_port callbacks. Implementing the current .udp_tunnel_sync callback would mean that the deleted tunnel port entry would be all zeros. This used to work on older firmware because it would not check the input when deleting a tunnel port. With newer firmware, the delete will now fail and subsequent tunnel port allocation will fail as a result.

[PATCH openEuler-22.03-LTS-SP1 4/6] bnxt_en: Query default VLAN before VNIC setup on a VF
by Baogen Shang 14 Mar '24

14 Mar '24

From: Somnath Kotur <somnath.kotur(a)broadcom.com> stable inclusion from stable-v5.10.184 commit deead0d8729f33f47cbedd0010a7e0e381527f9b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8L4MY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 1a9e4f501bc6ff1b6ecb60df54fbf2b54db43bfe ] We need to call bnxt_hwrm_func_qcfg() on a VF to query the default VLAN that may be setup by the PF. If a default VLAN is enabled, the VF cannot support VLAN acceleration on the receive side and the VNIC must be setup to strip out the default VLAN tag. If a default VLAN is not enabled, the VF can support VLAN acceleration on the receive side. The VNIC should be set up to strip or not strip the VLAN based on the RX VLAN acceleration setting. Without this call to determine the default VLAN before calling bnxt_setup_vnic(), the VNIC may not be set up correctly. For example, bnxt_setup_vnic() may set up to strip the VLAN tag based on stale default VLAN information. If RX VLAN acceleration is not enabled, the VLAN tag will be incorrectly stripped and the RX data path will not work correctly.

Firmware on 5731X/5741X and newer chips does not support this reset type. When bnxt_reset() issues a series of resets, this PROC AP reset may actually fail on these newer chips because the firmware is not ready to accept this unsupported command yet. Avoid this unnecessary error by skipping this reset type on chips that don't support it.

[PATCH OLK-6.6] iommu/iova: avoid softlockup in fq_flush_timeout
by Zhang Zekun 14 Mar '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8ZE0I CVE: NA -------------------------------- There is a softlockup undering cpu pressure test. ... pc : _raw_spin_unlock_irqrestore+0x14/0x78 lr : fq_flush_timeout+0x94/0x118 ... Call trace: _raw_spin_unlock_irqrestore+0x14/0x78 call_timer_fn+0x3c/0x1d0 expire_timers+0xcc/0x190 run_timer_softirq+0xfc/0x268 __do_softirq+0x128/0x3dc ____do_softirq+0x18/0x30 call_on_irq_stack+0x24/0x30 do_softirq_own_stack+0x24/0x38 irq_exit_rcu+0xc0/0xe8 el1_interrupt+0x48/0xc0 el1h_64_irq_handler+0x18/0x28 el1h_64_irq+0x78/0x80 __schedule+0xf28/0x12a0 schedule+0x3c/0x108 schedule_timeout+0xa0/0x1d0 pktgen_thread_worker+0x1180/0x15d0 kthread+0x120/0x130 ret_from_fork+0x10/0x20 This is because the timer callback fq_flush_timeout may run more than 10ms, and timer may be processed continuously in the softirq so trigger softlockup. We can use work to deal with fq_ring_free for each cpu which may take long time, that to avoid triggering softlockup.
