[PATCH 4.14 1/2] PCI: aardvark: Clear all MSIs at setup

by Marek Behún

From: Pali Rohár <pali(a)kernel.org> [ Upstream commit 7d8dc1f7cd007a7ce94c5b4c20d63a8b8d6d7751 ] We already clear all the other interrupts (ISR0, ISR1, HOST_CTRL_INT). Define a new macro PCIE_MSI_ALL_MASK and do the same clearing for MSIs, to ensure that we don't start receiving spurious interrupts. Use this new mask in advk_pcie_handle_msi(); Link: https://lore.kernel.org/r/20211130172913.9727-5-kabel@kernel.org Signed-off-by: Pali Rohár <pali(a)kernel.org> Signed-off-by: Marek Behún <kabel(a)kernel.org> Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi(a)arm.com> Signed-off-by: Marek Behún <kabel(a)kernel.org> --- drivers/pci/host/pci-aardvark.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/pci/host/pci-aardvark.c b/drivers/pci/host/pci-aardvark.c index 124fd7cb5da5..b7ff0774b165 100644 --- a/drivers/pci/host/pci-aardvark.c +++ b/drivers/pci/host/pci-aardvark.c @@ -104,6 +104,7 @@ #define PCIE_MSI_ADDR_HIGH_REG (CONTROL_BASE_ADDR + 0x54) #define PCIE_MSI_STATUS_REG (CONTROL_BASE_ADDR + 0x58) #define PCIE_MSI_MASK_REG (CONTROL_BASE_ADDR + 0x5C) +#define PCIE_MSI_ALL_MASK GENMASK(31, 0) #define PCIE_MSI_PAYLOAD_REG (CONTROL_BASE_ADDR + 0x9C) #define PCIE_MSI_DATA_MASK GENMASK(15, 0) @@ -490,6 +491,7 @@ static void advk_pcie_setup_hw(struct advk_pcie *pcie) advk_writel(pcie, reg, PCIE_CORE_CTRL2_REG); /* Clear all interrupts */ + advk_writel(pcie, PCIE_MSI_ALL_MASK, PCIE_MSI_STATUS_REG); advk_writel(pcie, PCIE_ISR0_ALL_MASK, PCIE_ISR0_REG); advk_writel(pcie, PCIE_ISR1_ALL_MASK, PCIE_ISR1_REG); advk_writel(pcie, PCIE_IRQ_ALL_MASK, HOST_CTRL_INT_STATUS_REG); @@ -502,7 +504,7 @@ static void advk_pcie_setup_hw(struct advk_pcie *pcie) advk_writel(pcie, PCIE_ISR1_ALL_MASK, PCIE_ISR1_MASK_REG); /* Unmask all MSI's */ - advk_writel(pcie, 0, PCIE_MSI_MASK_REG); + advk_writel(pcie, ~(u32)PCIE_MSI_ALL_MASK, PCIE_MSI_MASK_REG); /* Enable summary interrupt for GIC SPI source */ reg = PCIE_IRQ_ALL_MASK & (~PCIE_IRQ_ENABLE_INTS_MASK); @@ -1038,7 +1040,7 @@ static void advk_pcie_handle_msi(struct advk_pcie *pcie) msi_mask = advk_readl(pcie, PCIE_MSI_MASK_REG); msi_val = advk_readl(pcie, PCIE_MSI_STATUS_REG); - msi_status = msi_val & ~msi_mask; + msi_status = msi_val & ((~msi_mask) & PCIE_MSI_ALL_MASK); for (msi_idx = 0; msi_idx < MSI_IRQ_NUM; msi_idx++) { if (!(BIT(msi_idx) & msi_status)) -- 2.35.1

[PATCH 5.15 00/30] PCIe Aardvark controller backports for 5.15

by Marek Behún

Hello Greg, Sasha, this is backport of all the recet changes for the Aardvark PCIe controller for 5.15. These include - memory leak fix in driver unbind - more complete driver unbind - fixes for MSI support - add MSI-X support, which fixes support for some cards - add ERR interrupt support (which we really missed when debugging) I also included some small cosmetic changes - this will make it easier to backport next fixes for the driver (there is another batch pending on linux-pci). Marek Marek Behún (5): PCI: aardvark: Make MSI irq_chip structures static driver structures PCI: aardvark: Make msi_domain_info structure a static driver structure PCI: aardvark: Use dev_fwnode() instead of of_node_to_fwnode(dev->of_node) PCI: aardvark: Drop __maybe_unused from advk_pcie_disable_phy() PCI: aardvark: Update comment about link going down after link-up Pali Rohár (25): PCI: pci-bridge-emul: Add description for class_revision field PCI: pci-bridge-emul: Add definitions for missing capabilities registers PCI: aardvark: Add support for DEVCAP2, DEVCTL2, LNKCAP2 and LNKCTL2 registers on emulated bridge PCI: aardvark: Clear all MSIs at setup PCI: aardvark: Comment actions in driver remove method PCI: aardvark: Disable bus mastering when unbinding driver PCI: aardvark: Mask all interrupts when unbinding driver PCI: aardvark: Fix memory leak in driver unbind PCI: aardvark: Assert PERST# when unbinding driver PCI: aardvark: Disable link training when unbinding driver PCI: aardvark: Disable common PHY when unbinding driver PCI: aardvark: Replace custom PCIE_CORE_INT_* macros with PCI_INTERRUPT_* PCI: aardvark: Rewrite IRQ code to chained IRQ handler PCI: aardvark: Check return value of generic_handle_domain_irq() when processing INTx IRQ PCI: aardvark: Refactor unmasking summary MSI interrupt PCI: aardvark: Add support for masking MSI interrupts PCI: aardvark: Fix setting MSI address PCI: aardvark: Enable MSI-X support PCI: aardvark: Add support for ERR interrupt on emulated bridge PCI: aardvark: Optimize writing PCI_EXP_RTCTL_PMEIE and PCI_EXP_RTSTA_PME on emulated bridge PCI: aardvark: Add support for PME interrupts PCI: aardvark: Fix support for PME requester on emulated bridge PCI: aardvark: Use separate INTA interrupt for emulated root bridge PCI: aardvark: Remove irq_mask_ack() callback for INTx interrupts PCI: aardvark: Don't mask irq when mapping drivers/pci/controller/pci-aardvark.c | 428 +++++++++++++++++++------- drivers/pci/pci-bridge-emul.c | 49 ++- 2 files changed, 371 insertions(+), 106 deletions(-) -- 2.35.1

[PATCH 5.17 00/19] PCIe Aardvark controller backports for 5.17

by Marek Behún

Hello Greg, Sasha, this is backport of all the recet changes for the Aardvark PCIe controller for 5.17. These include - fixes for MSI support - add MSI-X support, which fixes support for some cards - add ERR interrupt support (which we really missed when debugging) As in series for 5.15, I included some small cosmetic changes - this will make it easier to backport next fixes for the driver (there is another batch pending on linux-pci). Marek Marek Behún (5): PCI: aardvark: Make MSI irq_chip structures static driver structures PCI: aardvark: Make msi_domain_info structure a static driver structure PCI: aardvark: Use dev_fwnode() instead of of_node_to_fwnode(dev->of_node) PCI: aardvark: Drop __maybe_unused from advk_pcie_disable_phy() PCI: aardvark: Update comment about link going down after link-up Pali Rohár (14): PCI: aardvark: Replace custom PCIE_CORE_INT_* macros with PCI_INTERRUPT_* PCI: aardvark: Rewrite IRQ code to chained IRQ handler PCI: aardvark: Check return value of generic_handle_domain_irq() when processing INTx IRQ PCI: aardvark: Refactor unmasking summary MSI interrupt PCI: aardvark: Add support for masking MSI interrupts PCI: aardvark: Fix setting MSI address PCI: aardvark: Enable MSI-X support PCI: aardvark: Add support for ERR interrupt on emulated bridge PCI: aardvark: Optimize writing PCI_EXP_RTCTL_PMEIE and PCI_EXP_RTSTA_PME on emulated bridge PCI: aardvark: Add support for PME interrupts PCI: aardvark: Fix support for PME requester on emulated bridge PCI: aardvark: Use separate INTA interrupt for emulated root bridge PCI: aardvark: Remove irq_mask_ack() callback for INTx interrupts PCI: aardvark: Don't mask irq when mapping drivers/pci/controller/pci-aardvark.c | 367 +++++++++++++++++++------- 1 file changed, 266 insertions(+), 101 deletions(-) -- 2.35.1

[PATCH v4.9] dm: interlock pending dm_io and dm_wait_for_bios_completion

by Mikulas Patocka

This is backport of the patch 9f6dc6337610 ("dm: interlock pending dm_io and dm_wait_for_bios_completion") for the kernel 4.9. The bugs fixed by this patch can cause random crashing when reloading dm table, so it is eligible for stable backport. Note that the kernel 4.9 uses md->pending to count the number of in-progress I/Os and md->pending is decremented after dm_stats_account_io, so the race condition doesn't really exist there (except for missing smp_rmb()). The percpu variable md->pending_io is not needed in the stable kernels, because md->pending counts the same value, so it is not backported.

[PATCH stable-v4.19 net] tcp: make sure treq->af_specific is initialized

by fruggeri＠arista.com

[ Upstream commit ba5a4fdd63ae0c575707030db0b634b160baddd7 ] syzbot complained about a recent change in TCP stack, hitting a NULL pointer [1] tcp request sockets have an af_specific pointer, which was used before the blamed change only for SYNACK generation in non SYNCOOKIE mode. tcp requests sockets momentarily created when third packet coming from client in SYNCOOKIE mode were not using treq->af_specific. Make sure this field is populated, in the same way normal TCP requests sockets do in tcp_conn_request(). [1] TCP: request_sock_TCPv6: Possible SYN flooding on port 20002. Sending cookies.

FAILED: patch "[PATCH] mm: fix unexpected zeroed page mapping with zram swap" failed to apply to 5.4-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 5.4-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From e914d8f00391520ecc4495dd0ca0124538ab7119 Mon Sep 17 00:00:00 2001 From: Minchan Kim <minchan(a)kernel.org> Date: Thu, 14 Apr 2022 19:13:46 -0700 Subject: [PATCH] mm: fix unexpected zeroed page mapping with zram swap Two processes under CLONE_VM cloning, user process can be corrupted by seeing zeroed page unexpectedly. CPU A CPU B do_swap_page do_swap_page SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path swap_readpage valid data swap_slot_free_notify delete zram entry swap_readpage zeroed(invalid) data pte_lock map the *zero data* to userspace pte_unlock pte_lock if (!pte_same) goto out_nomap; pte_unlock return and next refault will read zeroed data The swap_slot_free_notify is bogus for CLONE_VM case since it doesn't increase the refcount of swap slot at copy_mm so it couldn't catch up whether it's safe or not to discard data from backing device. In the case, only the lock it could rely on to synchronize swap slot freeing is page table lock. Thus, this patch gets rid of the swap_slot_free_notify function. With this patch, CPU A will see correct data.

However, most of cases of zram uses no readahead and do_swap_page is followed by swap_free so it will free the compressed form from in zram quickly.

[PATCH] udf: Avoid using stale lengthOfImpUse

by Jan Kara

udf_write_fi() uses lengthOfImpUse of the entry it is writing to. However this field has not yet been initialized so it either contains completely bogus value or value from last directory entry at that place. In either case this is wrong and can lead to filesystem corruption or kernel crashes.
