2024-10-29wwan: core: Pass string literal as format argument of dev_set_name()Simon Horman
Both gcc-14 and clang-18 report that passing a non-string literal as the format argument of dev_set_name() is potentially insecure. E.g. clang-18 says: drivers/net/wwan/wwan_core.c:442:34: warning: format string is not a string literal (potentially insecure) [-Wformat-security] 442 | return dev_set_name(&port->dev, buf); | ^~~ drivers/net/wwan/wwan_core.c:442:34: note: treat the string as an argument to avoid this 442 | return dev_set_name(&port->dev, buf); | ^ | "%s", It is always the case where the contents of mod is safe to pass as the format argument. That is, in my understanding, it never contains any format escape sequences. But, it seems better to be safe than sorry. And, as a bonus, compiler output becomes less verbose by addressing this issue as suggested by clang-18. Compile tested only. No functional change intended.

2024-10-29PCI: Fix pci_enable_acs() support for the ACS quirksJason Gunthorpe
There are ACS quirks that hijack the normal ACS processing and deliver to to special quirk code. The enable path needs to call pci_dev_specific_enable_acs() and then pci_dev_specific_acs_enabled() will report the hidden ACS state controlled by the quirk. The recent rework got this out of order and we should try to call pci_dev_specific_enable_acs() regardless of any actual ACS support in the device. As before command line parameters that effect standard PCI ACS don't interact with the quirk versions, including the new config_acs= option.

On this Cisco MX60W, u-boot sets the local-mac-address property. Unfortunately by default, the MAC is wrong and is actually located on a UBI partition. Which means nvmem needs to be used to grab it.

2024-10-29ice: fix crash on probe for DPLL enabled E810 LOMArkadiusz Kubalewski
The E810 Lan On Motherboard (LOM) design is vendor specific. Intel provides the reference design, but it is up to vendor on the final product design. For some cases, like Linux DPLL support, the static values defined in the driver does not reflect the actual LOM design. Current implementation of dpll pins is causing the crash on probe of the ice driver for such DPLL enabled E810 LOM designs: WARNING: (...) at drivers/dpll/dpll_core.c:495 dpll_pin_get+0x2c4/0x330 ...

The number of dpll pins enabled by LOM vendor is greater than expected and defined in the driver for Intel designed NICs, which causes the crash. Prevent the crash and allow generic pin initialization within Linux DPLL subsystem for DPLL enabled E810 LOM designs. Newly designed solution for described issue will be based on "per HW design" pin initialization. It requires pin information dynamically acquired from the firmware and is already in progress, planned for next-tree only.

2024-10-29igb: Disable threaded IRQ for igb_msix_otherWander Lairson Costa
During testing of SR-IOV, Red Hat QE encountered an issue where the ip link up command intermittently fails for the igbvf interfaces when using the PREEMPT_RT variant. Investigation revealed that e1000_write_posted_mbx returns an error due to the lack of an ACK from e1000_poll_for_ack. The underlying issue arises from the fact that IRQs are threaded by default under PREEMPT_RT. While the exact hardware details are not available, it appears that the IRQ handled by igb_msix_other must be processed before e1000_poll_for_ack times out. However, e1000_write_posted_mbx is called with preemption disabled, leading to a scenario where the IRQ is serviced only after the failure of e1000_write_posted_mbx. To resolve this, we set IRQF_NO_THREAD for the affected interrupt, ensuring that the kernel handles it immediately, thereby preventing the aforementioned error. Reproducer: #!/bin/bash # echo 2 > /sys/class/net/ens14f0/device/sriov_numvfs ipaddr_vlan=3 nic_test=ens14f0 vf=${nic_test}v0 while true; do ip link set ${nic_test} mtu 1500 ip link set ${vf} mtu 1500 ip link set $vf up ip link set ${nic_test} vf 0 vlan ${ipaddr_vlan} ip addr add 172.30.${ipaddr_vlan}.1/24 dev ${vf} ip addr add 2021:db8:${ipaddr_vlan}::1/64 dev ${vf} if ! ip link show $vf | grep 'state UP'; then echo 'Error found' break fi ip link set $vf down done Signed-off-by: Wander Lairson Costa <wander@redhat.com> Fixes: 9d5c824399de ("igb: PCI-Express 82575 Gigabit Ethernet driver") Reported-by: Yuying Ma <yuma@redhat.com> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Tested-by: Rafal Romanowski <rafal.romanowski@intel.com> Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2024-10-29net: stmmac: TSO: Fix unbalanced DMA map/unmap for non-paged SKB dataFurong Xu
In case the non-paged data of a SKB carries protocol header and protocol payload to be transmitted on a certain platform that the DMA AXI address width is configured to 40-bit/48-bit, or the size of the non-paged data is bigger than TSO_MAX_BUFF_SIZE on a certain platform that the DMA AXI address width is configured to 32-bit, then this SKB requires at least two DMA transmit descriptors to serve it. For example, three descriptors are allocated to split one DMA buffer mapped from one piece of non-paged data: dma_desc[N + 0], dma_desc[N + 1], dma_desc[N + 2]. Then three elements of tx_q->tx_skbuff_dma[] will be allocated to hold extra information to be reused in stmmac_tx_clean(): tx_q->tx_skbuff_dma[N + 0], tx_q->tx_skbuff_dma[N + 1], tx_q->tx_skbuff_dma[N + 2]. Now we focus on tx_q->tx_skbuff_dma[entry].buf, which is the DMA buffer address returned by DMA mapping call. stmmac_tx_clean() will try to unmap the DMA buffer _ONLY_IF_ tx_q->tx_skbuff_dma[entry].buf is a valid buffer address. The expected behavior that saves DMA buffer address of this non-paged data to tx_q->tx_skbuff_dma[entry].buf is: tx_q->tx_skbuff_dma[N + 0].buf = NULL; tx_q->tx_skbuff_dma[N + 1].buf = NULL; tx_q->tx_skbuff_dma[N + 2].buf = dma_map_single(); Unfortunately, the current code misbehaves like this: tx_q->tx_skbuff_dma[N + 0].buf = dma_map_single(); tx_q->tx_skbuff_dma[N + 1].buf = NULL; tx_q->tx_skbuff_dma[N + 2].buf = NULL; On the stmmac_tx_clean() side, when dma_desc[N + 0] is closed by the DMA engine, tx_q->tx_skbuff_dma[N + 0].buf is a valid buffer address obviously, then the DMA buffer will be unmapped immediately. There may be a rare case that the DMA engine does not finish the pending dma_desc[N + 1], dma_desc[N + 2] yet. Now things will go horribly wrong, DMA is going to access a unmapped/unreferenced memory region, corrupted data will be transmited or iommu fault will be triggered :( In contrast, the for-loop that maps SKB fragments behaves perfectly as expected, and that is how the driver should do for both non-paged data and paged frags actually. This patch corrects DMA map/unmap sequences by fixing the array index for tx_q->tx_skbuff_dma[entry].buf when assigning DMA buffer address.

2024-10-29s390/pkey: Add new pkey handler module pkey-uvHarald Freudenberger
This new pkey handler module supports the conversion of Ultravisor retrievable secrets to protected keys. The new module pkey-uv.ko is able to retrieve and verify protected keys backed up by the Ultravisor layer which is only available within protected execution environment. The module is only automatically loaded if there is the UV CPU feature flagged as available. Additionally on module init there is a check for protected execution environment and for UV supporting retrievable secrets. Also if the kernel is not running as a protected execution guest, the module unloads itself with errno ENODEV. The pkey UV module currently supports these Ultravisor secrets and is able to retrieve a protected key for these UV secret types: - UV_SECRET_AES_128 - UV_SECRET_AES_192 - UV_SECRET_AES_256 - UV_SECRET_AES_XTS_128 - UV_SECRET_AES_XTS_256 - UV_SECRET_HMAC_SHA_256 - UV_SECRET_HMAC_SHA_512 - UV_SECRET_ECDSA_P256 - UV_SECRET_ECDSA_P384 - UV_SECRET_ECDSA_P521 - UV_SECRET_ECDSA_ED25519 - UV_SECRET_ECDSA_ED448 Signed-off-by: Harald Freudenberger <freude@linux.ibm.com> Reviewed-by: Holger Dengler <dengler@linux.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>

2024-10-29s390/pkey: Rework pkey verify for protected keysHarald Freudenberger
Rework the verification of protected keys by simple check for the correct AES wrapping key verification pattern. A protected key always carries the AES wrapping key verification pattern within the blob. The old code really used the protected key for an en/decrypt operation and by doing so, verified the AES WK VP. But a much simpler and more generic way is to extract the AES WK VP value from the key and compare it with AES WK VP from a freshly created dummy protected key. This also eliminates the limitation to only be able to verify AES protected keys. With this change any kind of known protected key can be verified.

By introducing a new inline function pkey_keytype_to_size() this can be centralized and the calling code can be reduced and simplified. With this also comes a slight rework of the generation of protected keys. Now the pkey_pckmo module is able to generate all but ECC keys.

Normally there is no need to enumerate retimers on the other side of the cable. This is only needed in special cases where user wants to run receiver lane margining against the downstream facing port of a retimer. Furthermore this might confuse the userspace tools such as fwupd because it cannot read the information it expects from these retimers. Fix this by changing the retimer enumeration code to add only on-board retimers when CONFIG_USB4_DEBUGFS_MARGINING is not enabled.
