2025-10-10tpm: use a map for tpm2_calc_ordinal_duration()Jarkko Sakkinen
The current shenanigans for duration calculation introduce too much complexity for a trivial problem, and further the code is hard to patch and maintain. Address these issues with a flat look-up table, which is easy to understand and patch. If leaf driver specific patching is required in future, it is easy enough to make a copy of this table during driver initialization and add the chip parameter back. 'chip->duration' is retained for TPM 1.x. As the first entry for this new behavior address TCG spec update mentioned in this issue: https://github.com/raspberrypi/linux/issues/7054 Therefore, for TPM_SelfTest the duration is set to 3000 ms. This does not categorize a as bug, given that this is introduced to the spec after the feature was originally made.

Now that there are easy-to-use HMAC-SHA256 library functions, use these in tpm2-sessions.c instead of open-coding the HMAC algorithm. Note that the new implementation correctly handles keys longer than 64 bytes (SHA256_BLOCK_SIZE), whereas the old implementation handled such keys incorrectly.

2025-10-10tpm: Compare HMAC values in constant timeEric Biggers
In tpm_buf_check_hmac_response(), compare the HMAC values in constant time using crypto_memneq() instead of in variable time using memcmp(). This is worthwhile to follow best practices and to be consistent with MAC comparisons elsewhere in the kernel. However, in this driver the side channel seems to have been benign: the HMAC input data is guaranteed to always be unique, which makes the usual MAC forgery via timing side channel not possible. Specifically, the HMAC input data in tpm_buf_check_hmac_response() includes the "our_nonce" field, which was generated by the kernel earlier, remains under the control of the kernel, and is unique for each call to tpm_buf_check_hmac_response().

2025-10-10tpm: Disable TPM2_TCG_HMAC by defaultJarkko Sakkinen
After reading all the feedback, right now disabling the TPM2_TCG_HMAC is the right call. Other views discussed: A. Having a kernel command-line parameter or refining the feature otherwise. This goes to the area of improvements. E.g., one example is my own idea where the null key specific code would be replaced with a persistent handle parameter (which can be *unambigously* defined as part of attestation process when done correctly). B. Removing the code. I don't buy this because that is same as saying that HMAC encryption cannot work at all (if really nitpicking) in any form. Also I disagree on the view that the feature could not be refined to something more reasoable. Also, both A and B are worst options in terms of backporting. Thuss, this is the best possible choice.

A regression was reported to me recently whereby /dev/fb0 had disappeared from a PowerBook G3 Series "Wallstreet". The problem shows up when the "video=ofonly" parameter is passed to the kernel, which is what the bootloader does when "no video driver" is selected. The cause of the problem is the "offb" string comparison, which got mangled when it got refactored. Fix it.

2025-10-09eth: fbnic: fix accounting of XDP packetsJakub Kicinski
Make XDP-handled packets appear in the Rx stats. The driver has been counting XDP_TX packets on the Tx ring, but there wasn't much accounting on the Rx side (the Rx bytes appear to be incremented on XDP_TX but XDP_DROP / XDP_ABORT are only counted as Rx drops). Counting XDP_TX packets (not just bytes) in Rx stats looks like a simple bug of omission. The XDP_DROP handling appears to be intentional. Whether XDP_DROP packets should be counted in interface-level Rx stats is a bit unclear historically. When we were defining qstats, however, we clarified based on operational experience that in this context: name: rx-packets doc: | Number of wire packets successfully received and passed to the stack. For drivers supporting XDP, XDP is considered the first layer of the stack, so packets consumed by XDP are still counted here. fbnic does not obey this requirement. Since XDP support has been added in current release cycle, instead of splitting interface and qstat handling - make them both follow the qstat definition. Another small tweak here is that we count bytes as received on the wire rather than post-XDP bytes (xdp_get_buff_len() vs skb->len).

2025-10-09eth: fbnic: fix missing programming of the default descriptorJakub Kicinski
XDP_TX typically uses no offloads. To optimize XDP we added a "default descriptor" feature to the chip, which allows us to send XDP frames with just the buffer descriptors (DMA address + length). All the metadata descriptors are derived from the queue config. Commit under Fixes missed adding setting the defaults up when transplanting the code from the prototype driver. Importantly after reset the "request completion" bit is not set. Packets still get sent but there's no completion, so ring is not cleaned up. We can send one ring's worth of packets and then will start dropping all frames that got the XDP_TX action from the XDP prog.

2025-10-08PCI: Fix regression in pci_bus_distribute_available_resources()Yangyu Chen
The refactoring in 4292a1e45fd4 ("PCI: Refactor distributing available memory to use loops") switched pci_bus_distribute_available_resources() to operate on an array of bridge windows. That accidentally looked up bus resources via pci_bus_resource_n() and then passed those pointers to helper routines that expect the resource to belong to the device. As soon as we execute that code, pci_resource_num() warned because the resource wasn't in the bridge's resource array. This happens on my AMD Strix Halo machine with Thunderbolt device; the error message is shown below: WARNING: CPU: 6 PID: 272 at drivers/pci/pci.h:471 pci_bus_distribute_available_resources+0x6ad/0x6d0 CPU: 6 UID: 0 PID: 272 Comm: irq/33-pciehp Not tainted 6.17.0+ #1 PREEMPT(voluntary) Hardware name: PELADN YO Series/YO1, BIOS 1.04 05/15/2025 RIP: 0010:pci_bus_distribute_available_resources+0x6ad/0x6d0 Call Trace: pci_bus_distribute_available_resources+0x590/0x6d0 pci_bridge_distribute_available_resources+0x62/0xb0 pci_assign_unassigned_bridge_resources+0x65/0x1b0 pciehp_configure_device+0x92/0x160 pciehp_handle_presence_or_link_change+0x1b5/0x350 pciehp_ist+0x147/0x1c0 Fix the regression by always fetching the resource directly from the bridge with pci_resource_n(bridge, PCI_BRIDGE_RESOURCES + i). This restores the original behaviour while keeping the refactored structure. Then we can successfully assign resources to the Thunderbolt device.

Brian has taken up that task which nobody else has wanted to do for close to a decade. Thanks Brian! This is all prerequisite work to get to the real task of improving the clk rate setting process. Once we have determine_rate() used everywhere, we'll be able to do things like chain the rate request structs in linked lists to order the rate setting operations or add more parameters without having to change every clk driver in existence. It's also nice to not have multiple ways to do something which just causes confusion for clk driver authors. Overall I'm glad this is getting done. Beyond this change we also have a tweak to the clk_lookup() function in the core framework to use hashing on the clk name instead of a clk tree walk with string comparisons. We _still_ rely on the clk name to be unique, because historically we've used globally unique strings to describe the clk tree topology. This tree walk becomes increasingly slow as more clks are added to the system. Searching from the roots for a duplicate is simple but pretty dumb and it wastes boot time so we're using a hash table as an improvement. Ideally we wouldn't rely on the strings to be unique at all, relegating them to simply debug information, but that is future work that will likely require some sort of Kconfig knob indicating strings aren't used for topology description. Outside of the core framework changes we have the usual new SoC support and fixes to clk drivers for things that were discovered once the clks were used by consumer drivers. Nothing in particular is jumping out at me in the "misc" pile, except maybe the Amlogic driver that has gone through a refactoring.

2025-10-07net/mlx5e: Prevent tunnel reformat when tunnel mode not allowedCarolina Jubran
When configuring IPsec packet offload in tunnel mode, the driver tries to create tunnel reformat objects unconditionally. This is incorrect, because tunnel mode is only permitted under specific encapsulation settings, and that decision is already made when the flow table is created. The offending commit attempted to block this case in the state add path, but the check there happens too late and does not prevent the reformat from being configured. Fix by taking short reservations for both the eswitch mode and the encap at the start of state setup. This preserves the block ordering (mode --> encap) used later: the mode is blocked during RX/TX get, and the encap is blocked during flow-table creation. This lets us fail early if either reservation cannot be obtained, it means a mode transition is underway or a conflicting configuration already owns encap. If both succeed, the flow-table path later takes the ownership and the reservations are released on exit.

2025-10-07net/mlx5: Prevent tunnel mode conflicts between FDB and NIC IPsec tablesCarolina Jubran
When creating IPsec flow tables with tunnel mode enabled, the driver uses mlx5_eswitch_block_encap() to prevent tunnel encapsulation conflicts across different domains (NIC_RX/NIC_TX and FDB), since the firmware doesn’t allow both at the same time. Currently, the driver attempts to reserve tunnel mode unconditionally for both NIC and FDB IPsec tables. This can lead to conflicting tunnel mode setups, for example, if a flow table was created in the FDB domain with tunnel offload enabled, and we later try to create another one in the NIC, or vice versa. To resolve this, adjust the blocking logic so that tunnel mode is only reserved by NIC flows. This ensures that tunnel offload is exclusively used in either the NIC or the FDB, and avoids unintended offload conflicts. Fixes: 1762f132d542 ("net/mlx5e: Support IPsec packet offload for RX in switchdev mode") Fixes: c6c2bf5db4ea ("net/mlx5e: Support IPsec packet offload for TX in switchdev mode") Signed-off-by: Carolina Jubran <cjubran@nvidia.com> Reviewed-by: Jianbo Liu <jianbol@nvidia.com> Reviewed-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Link: https://patch.msgid.link/1759652999-858513-2-git-send-email-tariqt@nvidia.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2025-10-07net: usb: asix: hold PM usage ref to avoid PM/MDIO + RTNL deadlockOleksij Rempel
Prevent USB runtime PM (autosuspend) for AX88772* in bind. usbnet enables runtime PM (autosuspend) by default, so disabling it via the usb_driver flag is ineffective. On AX88772B, autosuspend shows no measurable power saving with current driver (no link partner, admin up/down). The ~0.453 W -> ~0.248 W drop on v6.1 comes from phylib powering the PHY off on admin-down, not from USB autosuspend. The real hazard is that with runtime PM enabled, ndo_open() (under RTNL) may synchronously trigger autoresume (usb_autopm_get_interface()) into asix_resume() while the USB PM lock is held. Resume paths then invoke phylink/phylib and MDIO, which also expect RTNL, leading to possible deadlocks or PM lock vs MDIO wake issues. To avoid this, keep the device runtime-PM active by taking a usage reference in ax88772_bind() and dropping it in unbind(). A non-zero PM usage count blocks runtime suspend regardless of userspace policy (.../power/control - pm_runtime_allow/forbid), making this approach robust against sysfs overrides. Holding a runtime-PM usage ref does not affect system-wide suspend; system sleep/resume callbacks continue to run as before.

2025-10-07Merge branch 'pm-cpufreq'Rafael J. Wysocki
Merge cpufreq fixes and cleanups, mostly on top of those fixes, for 6.18-rc1: - Make cpufreq drivers setting the default CPU transition latency to CPUFREQ_ETERNAL specify a proper default transition latency value instead which addresses a regression introduced during the 6.6 cycle that broke CPUFREQ_ETERNAL handling (Rafael Wysocki) - Make the cpufreq CPPC driver use a proper transition delay value when CPUFREQ_ETERNAL is returned by cppc_get_transition_latency() to indicate an error condition (Rafael Wysocki) - Make cppc_get_transition_latency() return a negative error code to indicate error conditions instead of using CPUFREQ_ETERNAL for this purpose and drop CPUFREQ_ETERNAL that has no other users (Rafael Wysocki, Gopi Krishna Menon) - Fix device leak in the mediatek cpufreq driver (Johan Hovold) - Set target frequency on all CPUs sharing a policy during frequency updates in the tegra186 cpufreq driver and make it initialize all cores to max frequencies (Aaron Kling) - Rust cpufreq helper cleanup (Thorsten Blum) * pm-cpufreq: docs/zh_CN: Fix malformed table docs/zh_TW: Fix malformed table cpufreq: Drop unused symbol CPUFREQ_ETERNAL ACPI: CPPC: Do not use CPUFREQ_ETERNAL as an error value cpufreq: CPPC: Avoid using CPUFREQ_ETERNAL as transition delay cpufreq: Make drivers using CPUFREQ_ETERNAL specify transition latency cpufreq: tegra186: Initialize all cores to max frequencies cpufreq: tegra186: Set target frequency for all cpus in policy rust: cpufreq: streamline find_supply_names cpufreq: mediatek: fix device leak on probe failure
2025-10-07Merge branches 'pm-core' and 'pm-runtime'Rafael J. Wysocki
Merge runtime PM framework updates and a core power management code fix for 6.18-rc1: - Make pm_runtime_put*() family of functions return 1 when the given device is already suspended which is consistent with the documentation (Brian Norris) - Add basic kunit tests for runtime PM API contracts and update return values in kerneldoc coments for the runtime PM API (Brian Norris, Dan Carpenter) - Add auto-cleanup macros for runtime PM "resume and get" and "get without resume" operations, use one of them in the PCI core and drop the existing "free" macro introduced for similar purpose, but somewhat cumbersome to use (Rafael Wysocki) - Make the core power management code avoid waiting on device links marked as SYNC_STATE_ONLY which is consistent with the handling of those device links elsewhere (Pin-yen Lin) * pm-core: PM: sleep: Do not wait on SYNC_STATE_ONLY device links * pm-runtime: PM: runtime: Fix error checking for kunit_device_register() PM: runtime: Introduce one more usage counter guard PM: runtime: Drop DEFINE_FREE() for pm_runtime_put() PCI/sysfs: Use runtime PM guard macro for auto-cleanup PM: runtime: Add auto-cleanup macros for "resume and get" operations PM: runtime: Update kerneldoc return codes PM: runtime: Make put{,_sync}() return 1 when already suspended PM: runtime: Add basic kunit tests for API contracts
