2022-12-28vdpa/mlx5: Fix rule forwarding VLAN to TIREli Cohen
Set the VLAN id to the header values field instead of overwriting the headers criteria field. Before this fix, VLAN filtering would not really work and tagged packets would be forwarded unfiltered to the TIR.

2022-12-28usb: fotg210: fix OTG-only buildArnd Bergmann
The fotg210 module combines the HCD and OTG drivers, which then fails to build when only the USB gadget support is enabled in the kernel but host support is not: aarch64-linux-ld: drivers/usb/fotg210/fotg210-core.o: in function `fotg210_init': fotg210-core.c:(.init.text+0xc): undefined reference to `usb_disabled' Move the check for usb_disabled() after the check for the HCD module, and let the OTG driver still be probed in this configuration. A nicer approach might be to have the common portion built as a library module, with the two platform other files registering their own platform_driver instances separately.

2022-12-28bnxt_en: Fix HDS and jumbo thresholds for RX packetsMichael Chan
The recent XDP multi-buffer feature has introduced regressions in the setting of HDS and jumbo thresholds. HDS was accidentally disabled in the nornmal mode without XDP. This patch restores jumbo HDS placement when not in XDP mode. In XDP multi-buffer mode, HDS should be disabled and the jumbo threshold should be set to the usable page size in the first page buffer.

2022-12-28bnxt_en: Fix first buffer size calculations for XDP multi-bufferMichael Chan
The size of the first buffer is always page size, and the useable space is the page size minus the offset and the skb_shared_info size. Make sure SKB and XDP buf sizes match so that the skb_shared_info is at the same offset seen from the SKB and XDP_BUF. build_skb() should be passed PAGE_SIZE. xdp_init_buff() should be passed PAGE_SIZE as well. xdp_get_shared_info_from_buff() will automatically deduct the skb_shared_info size if the XDP buffer has frags. There is no need to keep bp->xdp_has_frags. Change BNXT_PAGE_MODE_BUF_SIZE to BNXT_MAX_PAGE_MODE_MTU_SBUF since this constant is really the MTU with ethernet header size subtracted. Also fix the BNXT_MAX_PAGE_MODE_MTU macro with proper parentheses.

On newer Tegra releases, early boot SID override programming and SID override programming during resume is handled by bootloader. In the function tegra186_mc_program_sid() which is getting removed, SID override register of all clients is written without checking if secure firmware has allowed write on it or not. If write is disabled by secure firmware then it can lead to errors coming from secure firmware and hang in kernel boot. Also, SID override is programmed on-demand during probe_finalize() call of IOMMU which is done in tegra186_mc_client_sid_override() in this same file. This function does it correctly by checking if write is permitted on SID override register. It also checks if SID override register is already written with correct value and skips re-writing it in that case.

2022-12-27ata: ahci: Fix PCS quirk application for suspendAdam Vodopjan
Since kernel 5.3.4 my laptop (ICH8M controller) does not see Kingston SV300S37A60G SSD disk connected into a SATA connector on wake from suspend. The problem was introduced in c312ef176399 ("libata/ahci: Drop PCS quirk for Denverton and beyond"): the quirk is not applied on wake from suspend as it originally was. It is worth to mention the commit contained another bug: the quirk is not applied at all to controllers which require it. The fix commit 09d6ac8dc51a ("libata/ahci: Fix PCS quirk application") landed in 5.3.8. So testing my patch anywhere between commits c312ef176399 and 09d6ac8dc51a is pointless. Not all disks trigger the problem. For example nothing bad happens with Western Digital WD5000LPCX HDD. Test hardware: - Acer 5920G with ICH8M SATA controller - sda: some SATA HDD connnected into the DVD drive IDE port with a SATA-IDE caddy. It is a boot disk - sdb: Kingston SV300S37A60G SSD connected into the only SATA port Sample "dmesg --notime | grep -E '^(sd |ata)'" output on wake: sd 0:0:0:0: [sda] Starting disk sd 2:0:0:0: [sdb] Starting disk ata4: SATA link down (SStatus 4 SControl 300) ata3: SATA link down (SStatus 4 SControl 300) ata1.00: ACPI cmd ef/03:0c:00:00:00:a0 (SET FEATURES) filtered out ata1.00: ACPI cmd ef/03:42:00:00:00:a0 (SET FEATURES) filtered out ata1: FORCE: cable set to 80c ata5: SATA link down (SStatus 0 SControl 300) ata3: SATA link down (SStatus 4 SControl 300) ata3: SATA link down (SStatus 4 SControl 300) ata3.00: disabled sd 2:0:0:0: rejecting I/O to offline device ata3.00: detaching (SCSI 2:0:0:0) sd 2:0:0:0: [sdb] Start/Stop Unit failed: Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK sd 2:0:0:0: [sdb] Synchronizing SCSI cache sd 2:0:0:0: [sdb] Synchronize Cache(10) failed: Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK sd 2:0:0:0: [sdb] Stopping disk sd 2:0:0:0: [sdb] Start/Stop Unit failed: Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK Commit c312ef176399 dropped ahci_pci_reset_controller() which internally calls ahci_reset_controller() and applies the PCS quirk if needed after that.

This was never properly done by the fabrics drivers, but they don't seem to care because there is no actual physical queue that can wrap around, but it became a problem when converting over the PCIe driver.

Instead, condition more strictly on how NET_DSA_MV88E6XXX_PTP's dependencies are met, making sure that it cannot be enabled when NET_DSA_MV88E6XXX=y and PTP_1588_CLOCK=m.

2022-12-26qlcnic: prevent ->dcb use-after-free on qlcnic_dcb_enable() failureDaniil Tatianin
adapter->dcb would get silently freed inside qlcnic_dcb_enable() in case qlcnic_dcb_attach() would return an error, which always happens under OOM conditions. This would lead to use-after-free because both of the existing callers invoke qlcnic_dcb_get_info() on the obtained pointer, which is potentially freed at that point. Propagate errors from qlcnic_dcb_enable(), and instead free the dcb pointer at callsite using qlcnic_dcb_free(). This also removes the now unused qlcnic_clear_dcb_ops() helper, which was a simple wrapper around kfree() also causing memory leaks for partially initialized dcb. Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.

2022-12-25treewide: Convert del_timer*() to timer_shutdown*()Steven Rostedt (Google)
Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed. The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case. This was created by using a coccinelle script and the following commands: $ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); ) $ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/ Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Pavel Machek <pavel@ucw.cz> [ LED ] Acked-by: Kalle Valo <kvalo@kernel.org> [ wireless ] Acked-by: Paolo Abeni <pabeni@redhat.com> [ networking ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The check_reserve_boundaries function uses a lot of kernel stack, and it gets inlined by clang, which makes __drm_test_mm_reserve use even more of it, to the point of hitting the warning limit: drivers/gpu/drm/tests/drm_mm_test.c:344:12: error: stack frame size (1048) exceeds limit (1024) in '__drm_test_mm_reserve' [-Werror,-Wframe-larger-than] When building with gcc, this does not happen, but the structleak plugin can similarly increase the stack usage and needs to be disabled, as we do for all other kunit users.
