For wrapped key HMAC algorithms, the key size is independent of the cryptographic key size. So there is no known size of the mac key in such cases. The desired key size can optionally be specified as argument when the dm-crypt device is configured via 'integrity_key_size:%u'. If no integrity_key_size argument is specified, the mac key size is still set to the digest size, as before. Increase version number to 1.28.0 so that support for the new argument can be detected by user space (i.e. cryptsetup).

However, there are a couple codepaths in the kernel where firmware file names contain string components that are passed through from a device or semi-privileged userspace; the ones I could find (not counting interfaces that require root privileges) are: - lpfc_sli4_request_firmware_update() seems to construct the firmware filename from "ModelName", a string that was previously parsed out of some descriptor ("Vital Product Data") in lpfc_fill_vpd() - nfp_net_fw_find() seems to construct a firmware filename from a model name coming from nfp_hwinfo_lookup(pf->hwinfo, "nffw.partno"), which I think parses some descriptor that was read from the device. (But this case likely isn't exploitable because the format string looks like "netronome/nic_%s", and there shouldn't be any *folders* starting with "netronome/nic_". The previous case was different because there, the "%s" is *at the start* of the format string.) - module_flash_fw_schedule() is reachable from the ETHTOOL_MSG_MODULE_FW_FLASH_ACT netlink command, which is marked as GENL_UNS_ADMIN_PERM (meaning CAP_NET_ADMIN inside a user namespace is enough to pass the privilege check), and takes a userspace-provided firmware name. (But I think to reach this case, you need to have CAP_NET_ADMIN over a network namespace that a special kind of ethernet device is mapped into, so I think this is not a viable attack path in practice.) Fix it by rejecting any firmware names containing ".." path components. For what it's worth, I went looking and haven't found any USB device drivers that use the firmware loader dangerously.

Only devices with drivers that have async_shutdown_enable enabled will be shut down asynchronously. This can dramatically reduce system shutdown/reboot time on systems that have multiple devices that take many seconds to shut down (like certain NVMe drives). On one system tested, the shutdown time went from 11 minutes without this patch to 55 seconds with the patch.

The 'goto' pattern in the case can be removed by refactoring. Introducing a new function called cxl_port_add() which is used to add the 'struct device' of a new cxl_port to device hierarchy, moving the functions needing the help of the 'goto' into cxl_port_add(), and using a scoped-based resource management __free() to drop the open coded put_device() and the 'goto' for the error cases.

Besides, adjust the order of the function parameters, the subject of cxl_dport_init_ras_reporting() is a cxl dport, so a struct cxl_dport as the first parameter of the function should be better. cxl_dport_map_regs() is used to map CXL RAS capability on a cxl dport, using cxl_dport_map_ras() as the function name.

This mode uses devices with non-power-of-2 sector size. The extra metadata after each sector are used to hold the integrity hash. This commit enhances the inline mode, so that there is automatic recalculation of the integrity hashes when the 'reclaculate' parameter is used. It allows us to activate the device instantly, and the recalculation is done on background. If the device is deactivated while recalculation is in progress, it will remember the point where it stopped and it will continue from this point when activated again.

However, in cxl_hdm_decode_init(), the validation for info->dvsec_range[] occurs in a for loop that iterates based on info->ranges. It may result in zero range to be validated but non-zero range not be validated, in turn, the number of allowed ranges is to be 0. Address it by only record non-zero ranges. This fix is not urgent as it requires a configuration that zeroes out the first dvsec range while populating the second. This has not been observed, but it is theoretically possible. If this gets picked up for -stable, no harm done, but there is no urgency to backport.

Dan points out in the thread that notifiers should be able to trust that it is safe to access static data. Region data is static once the device is realized and until it's destruction. Thus it is better to manage the notifiers within the region driver. Remove the need for a lock by ensuring the notifiers are active only during the region's lifetime. Furthermore, remove cxl_region_nid() because resource can't be NULL while the region is stable.

Because the superblock is currently 64 bytes, this really verifies mac_size <= 448. This confuses smatch into thinking that mac_size may be as large as 448, which is inconsistent with the later code that assumes the MAC fits in a buffer of size HASH_MAX_DIGESTSIZE (64). In fact mac_size <= HASH_MAX_DIGESTSIZE is guaranteed by the crypto API, as that is the whole point of HASH_MAX_DIGESTSIZE. But, let's be defensive and explicitly check for this. This suppresses the false positive smatch warning. It does not fix an actual bug.

Also we had to split single ep93xx platform_device into multiple, one for each port, without this we can't do a full working transition from legacy platform code into device tree capable.

charset=UTF-8 Content-Transfer-Encoding: 8bit A previous change was introduced to prevent data loss during a power-on reset when a tape is present inside the drive. This commit set the "pos_unknown" flag to true to avoid operations that could compromise data by performing actions from an untracked position. The relevant change is commit 9604eea5bd3a ("scsi: st: Add third party poweron reset handling") As a consequence of this change, a new issue has surfaced: the driver now returns an "Input/output error" even for empty drives when the drive, host, or bus is reset. This issue stems from the "flush_buffer" function, which first checks whether the "pos_unknown" flag is set. If the flag is set, the user will encounter an "Input/output error" until the tape position is known again. This behavior differs from the previous implementation, where empty drives were not affected at system start up time, allowing tape software to send commands to the driver to retrieve the drive's status and other information. The current behavior prioritizes the "pos_unknown" flag over the "ST_NO_TAPE" status, leading to issues for software that detects drives during system startup. This software will receive an "Input/output error" until a tape is loaded and its position is known. To resolve this, the "ST_NO_TAPE" status should take priority when the drive is empty, allowing communication with the drive following a power-on reset. At the same time, the change should continue to protect data by maintaining the "pos_unknown" flag when the drive contains a tape and its position is unknown.

If the max transfer of the backing device decreases, this can cause issues with previously discovered LUNs. This patch accomplishes two things. First, it changes the default ibmvfc max transfer value to 1MB. This is generally supported by all backing devices, which should mitigate this issue out of the box. Secondly, it adds a module parameter, enabling a user to increase the max transfer value to values that are larger than 1MB, as long as they have configured these larger values on the virtual I/O server as well.

The issue is in lpfc_els_flush_cmd(), where the driver attempts to recover outstanding ELS sgls when walking the txcmplq.

The use of EFI_LOADER_DATA here results in the region being left unreserved in the E820 memory map constructed by the EFI stub, and this is the memory description that is passed on to the incoming kernel by kexec, which is therefore unaware that the region should be reserved. Even though the utility of the TPM2 event log after a kexec is questionable, any corruption might send the parsing code off into the weeds and crash the kernel. So let's use EFI_ACPI_RECLAIM_MEMORY instead, which is always treated as reserved by the E820 conversion logic.

The following sequence of commands causes a livelock - there will be workqueue process looping and consuming 100% CPU: dmsetup create --notable test truncate -s 1MiB testdata losetup /dev/loop0 testdata dmsetup load test --table '0 2048 linear /dev/loop0 0' dd if=/dev/zero of=/dev/dm-0 bs=16k count=1 conv=fdatasync The livelock is caused by the commit fa247089de99. The commit claims that it fixes a race condition, however, it is unknown what the actual race condition is and what program is involved in the race condition. When the inactive table is loaded, the nodes /dev/dm-0 and /sys/block/dm-0 are created. /dev/dm-0 has zero size at this point. When the device is suspended and resumed, the nodes /dev/mapper/test and /dev/disk/* are created. If some program opens a block device before it is created by dmsetup or lvm, the program is buggy, so dm could just report an error as it used to do before.

This is required by the AUX_PHY_WAKE/ML_PHY_LOCK signaling initiated by the HW automatically to re-enable the main link after it got disabled in power saving states (see eDP v1.4b, sections 5.1, 6.1.3.3.1.1). The Panel Replay mode on non-eDP outputs on the other hand is only supported by keeping the main link active, thus not requiring the above AUX_PHY_WAKE/ML_PHY_LOCK signaling (eDP v1.4b, section 6.1.3.3.1.2). Thus enabling the AUX IO power for this case is not required either. Based on the above enable the AUX IO power only for eDP/PSR outputs. Bspec: 49274, 53370 v2: - Add a TODO comment to adjust the requirement for AUX IO based on whether the ALPM/main-link off mode gets enabled.

This has been mitigated in the PMFW to a degree, but there is still a small chance that the bus will be busy. When the read fails during RAS init, that disables page retirement altogether, which is obviously not ideal. To try to avoid that situation, set the eeprom_read function to retry once if the first read fails, specifically for smu_v13_0_6.

A VESA SCR introduced a new max uncompressed pixel rate cap register that we can use to handle these edge cases. [HOW] SST: Read caps from link and invalidate timings that exceed the max limit but do not support DSC. Then check for options override when determining BPP. MST: Read caps from virtual DPCD peer device or daisy chained SST monitor and set validation set BPPs to max if pixel rate exceeds uncompressed limit. Validation set optimization continues as normal.

This simple method does not take into account where multiple targets sharing under a switch or a root port where the aggregated bandwidth can be greater than the upstream link of the switch. To accurately account for the shared upstream uplink cases, a new update function is introduced by walking from the leaves to the root of the hierarchy and clamp the bandwidth in the process as needed. This process is done when all the targets for a region are present but before the final values are send to the HMAT handling code cached access_coordinate targets. The original perf calculation path was kept to calculate the latency performance data that does not require the shared link consideration. The shared upstream link calculation is done as a second pass when all the endpoints have arrived. Testing is done via qemu with CXL hierarchy. run_qemu[1] is modified to support several CXL hierarchy layouts. The following layouts are tested: HB: Host Bridge RP: Root Port SW: Switch EP: End Point 2 HB 2 RP 2 EP: resulting bandwidth: 624 1 HB 2 RP 2 EP: resulting bandwidth: 624 2 HB 2 RP 2 SW 4 EP: resulting bandwidth: 624 Current testing, perf number from SRAT/HMAT is hacked into the kernel code. However with new QEMU support of Generic Target Port that's incoming, the perf data injection is no longer needed.

To solve that problem, add a new function to clear all vpci device state when device is reset on dom0 side. And call that function in pcistub_init_device. Because when using "pci-assignable-add" to assign a passthrough device in Xen, it will reset passthrough device and the vpci state will out of date, and then device will fail to restore bar state.

This logic is racy since CP can update the VMID-PASID mapping anytime especially when there are more processes than number of vmids. Update the logic to calculate CU occupancy by matching doorbell offset of the queue with valid wave counts against the process's queues.

This could fail, e.g. under memory pressure, when the IOMMU driver just can't allocate more memory for page tables. While the code tries to handle this in the path below the err_unmap label it erroneously unmaps one entry from the sq's FIFO list of active mappings. Since the current map attempt failed this unmap is removing some random DMA mapping that might still be required. If the PCI function now presents that IOVA, the IOMMU may assumes a rogue DMA access and e.g. on s390 puts the PCI function in error state. The erroneous behavior was seen in a stress-test environment that created memory pressure.

This might result in starving other threads waiting to run on the cpu. Numbers I got from testing ConnectX-5 Ex MCX516A-CDAT in the lab: - mlx5_vsc_gw_read_block_fast() was called with length = 1310716. - mlx5_vsc_gw_read_fast() reads 4 bytes at a time. It was not used to read the entire 1310716 bytes. It was called 53813 times because there are jumps in read_addr. - On average mlx5_vsc_gw_read_fast() took 35284.4ns. - In total mlx5_vsc_wait_on_flag() called vsc_read() 54707 times. The average time for each call was 17548.3ns. In some instances vsc_read() was called more than one time when the flag was not set. As expected the thread released the cpu after 16 iterations in mlx5_vsc_wait_on_flag(). - Total time to read crdump was 35284.4ns * 53813 ~= 1.898s. It was seen in the field that crdump can take more than 5 seconds to complete. During that time mlx5_vsc_wait_on_flag() did not release the cpu because it did not complete 16 iterations. It is believed that pci config reads were slow. Adding cond_resched() every 128 register read improves the situation. In the common case the, crdump takes ~1.8989s, the thread yields the cpu every ~4.51ms. If crdump takes ~5s, the thread yields the cpu every ~18.0ms.

The meaning of this flag is as follows. 1. If a C-state from the custom table is defined in ACPI _CST (matched by the mwait hint), then enable this C-state. 2. Otherwise, disable this C-state, unless the C-sate definition in the custom table has the 'CPUIDLE_FLAG_ALWAYS_ENABLE' flag set, in which case enabled it. The goal is to honor BIOS C6 settings - If BIOS disables C6, disable it by default in the OS too (but it can be enabled via sysfs). This works well on Xeons that expose only one flavor of C6. This are all Xeons except for the newest Granite Rapids (GNR) and Sierra Forest (SRF). The problem ~~~~~~~~~~~ GNR and SRF have 2 flavors of C6: C6/C6P on GNR, C6S/C6SP on SRF. The the "P" flavor allows for the package C6, while the "non-P" flavor allows only for core/module C6. As far as this patch is concerned, both GNR and SRF platforms are handled the same way. Therefore, further discussion is focused on GNR, but it applies to SRF as well. On Intel Xeon platforms, BIOS exposes only 2 ACPI C-states: C1 and C2. Well, depending on BIOS settings, C2 may be named as C3. But there still will be only 2 states - C1 and C3. But this is a non-essential detail, so further discussion is focused on the ACPI C1 and C2 case. On pre-GNR/SRF Xeon platforms, ACPI C1 is mapped to C1 or C1E, and ACPI C2 is mapped to C6. The 'use_acpi' flag works just fine: * If ACPI C2 enabled, enable C6. * Otherwise, disable C6. However, on GNR there are 2 flavors of C6, so BIOS maps ACPI C2 to either C6 or C6P, depending on the user settings. As a result, due to the 'use_acpi' flag, 'intel_idle' disables least one of the C6 flavors. BIOS | OS | Verdict ----------------------------------------------------|--------- ACPI C2 disabled | C6 disabled, C6P disabled | OK ACPI C2 mapped to C6 | C6 enabled, C6P disabled | Not OK ACPI C2 mapped to C6P | C6 disabled, C6P enabled | Not OK The goal of 'use_acpi' is to honor BIOS ACPI C2 disabled case, which works fine. But if ACPI C2 is enabled, the goal is to enable all flavors of C6, not just one of the flavors. This was overlooked when enabling GNR/SRF platforms. In other words, before GNR/SRF, the ACPI C2 status was binary - enabled or disabled. But it is not binary on GNR/SRF, however the goal is to continue treat it as binary. The fix ~~~~~~~ Notice, that current algorithm matches ACPI and custom table C-states by the mwait hint. However, mwait hint consists of the 'state' and 'sub-state' parts, and all C6 flavors have the same state value of 0x20, but different sub-state values. Introduce new C-state table flag - CPUIDLE_FLAG_PARTIAL_HINT_MATCH and add it to both C6 flavors of the GNR/SRF platforms. When matching ACPI _CST and custom table C-states, match only the start part if the C-state has CPUIDLE_FLAG_PARTIAL_HINT_MATCH, other wise match both state and sub-state parts (as before). With this fix, GNR C-states enabled/disabled status looks like this. BIOS | OS ---------------------------------------------------- ACPI C2 disabled | C6 disabled, C6P disabled ACPI C2 mapped to C6 | C6 enabled, C6P enabled ACPI C2 mapped to C6P | C6 enabled, C6P enabled Possible alternative ~~~~~~~~~~~~~~~~~~~~ The alternative would be to remove 'use_acpi' flag for GNR and SRF. This would be a simpler solution, but it would violate the principle of least surprise - users of Xeon platforms are used to the fact that intel_idle honors C6 enabled/disabled flag. It is more consistent user experience if GNR/SRF continue doing so. How tested ~~~~~~~~~~ Tested on GNR and SRF platform with all the 3 BIOS configurations: ACPI C2 disabled, mapped to C6/C6S, mapped to C6P/C6SP. Tested on Ice lake Xeon and Sapphire Rapids Xeon platforms with ACPI C2 enabled and disabled, just to verify that the patch does not break older Xeons.

In theory, this could be used to subvert security, because an attacker can create sectors that return error with the Write Uncorrectable command. Some programs may misbehave if they have to deal with EIO. This commit fixes dm-verity, so that if "panic_on_corruption" or "restart_on_corruption" was specified and an I/O error happens, the machine will panic or restart. This commit also changes kernel_restart to emergency_restart - kernel_restart calls reboot notifiers and these reboot notifiers may wait for the bio that failed. emergency_restart doesn't call the notifiers.

The mentioned data is observed on the wire. This patch uses skb_put_padto() to pad Ethernet frames properly. The mentioned function zeroes the expanded buffer. In case the packet cannot be padded it is silently dropped. Statistics are also not incremented. This driver does not support statistics in the old 32-bit format or the new 64-bit format. These will be added in the future. In its current form, the patch should be easily backported to stable versions. Ethernet MACs on Amazon-SE and Danube cannot do padding of the packets in hardware, so software padding must be applied.

charset=UTF-8 Content-Transfer-Encoding: 8bit Increase the timeout for checking the busy bit of the VLAN Tag register from 10µs to 500ms. This change is necessary to accommodate scenarios where Energy Efficient Ethernet (EEE) is enabled. Overnight testing revealed that when EEE is active, the busy bit can remain set for up to approximately 300ms. The new 500ms timeout provides a safety margin.

The problem that the commit e6a3531dd542cb127c8de32ab1e54a48ae19962b fixes was reported as a security bug, but Google engineers working on Android and ChromeOS didn't want to change the default behavior, they want to get -EIO rather than restarting the system, so I am reverting that commit. Note also that calling machine_restart from the I/O handling code is potentially unsafe (the reboot notifiers may wait for the bio that triggered the restart), but Android uses the reboot notifiers to store the reboot reason into the PMU microcontroller, so machine_restart must be used.
