2023-10-20PNP: replace deprecated strncpy() with memcpy()Justin Stitt
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous interfaces. After having precisely calculated the lengths and ensuring we don't overflow the buffer, this really decays to just a memcpy. Let's not use a C string api as it makes the intention of the code confusing. It'd be nice to use strscpy() in this case (as we clearly want NUL-termination) because it'd clean up the code a bit. However, I don't quite know enough about what is going on here to justify a drop-in replacement -- too much bit magic and why (PNP_NAME_LEN - 2)? I'm afraid using strscpy() may result in copying too many or too few bytes into our dev->name buffer resulting in different behavior. At least using memcpy() we can ensure the behavior is exactly the same. Side note: NUL-padding is not required because insert_device() calls pnpbios_parse_data_stream() with a zero-allocated `dev`: 299 | static int __init insert_device(struct pnp_bios_node *node) { ... 312 | dev = pnp_alloc_dev(&pnpbios_protocol, node->handle, id); ... 316 | pnpbios_parse_data_stream(dev, node); then pnpbios_parse_data_stream() calls pnpbios_parse_compatible_ids().

2023-10-20PNP: ACPI: replace deprecated strncpy() with strscpy()Justin Stitt
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We know dev->name should be NUL-terminated based on the presence of a manual NUL-byte assignment. NUL-padding is not required as dev is already zero-allocated which renders any further NUL-byte assignments redundant: dev = pnp_alloc_dev(&pnpacpi_protocol, num, pnpid); ---> dev = kzalloc(sizeof(struct pnp_dev), GFP_KERNEL); Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. This simplifies the code and makes the intent/behavior more obvious.

2023-10-20thermal: core: Don't update trip points inside the hysteresis rangeNícolas F. R. A. Prado
When searching for the trip points that need to be set, the nearest higher trip point's temperature is used for the high trip, while the nearest lower trip point's temperature minus the hysteresis is used for the low trip. The issue with this logic is that when the current temperature is inside a trip point's hysteresis range, both high and low trips will come from the same trip point. As a consequence instability can still occur like this: * the temperature rises slightly and enters the hysteresis range of a trip point * polling happens and updates the trip points to the hysteresis range * the temperature falls slightly, exiting the hysteresis range, crossing the trip point and triggering an IRQ, the trip points are updated * repeat So even though the current hysteresis implementation prevents instability from happening due to IRQs triggering on the same temperature value, both ways, it doesn't prevent it from happening due to an IRQ on one way and polling on the other. To properly implement a hysteresis behavior, when inside the hysteresis range, don't update the trip points. This way, the previously set trip points will stay in effect, which will in a way remember the previous state (if the temperature signal came from above or below the range) and therefore have the right trip point already set. The exception is if there was no previous trip point set, in which case a previous state doesn't exist, and so it's sensible to allow the hysteresis range as trip points. The following logs show the current behavior when running on a real machine: [ 202.524658] thermal thermal_zone0: new temperature boundaries: -2147483647 < x < 40000 203.562817: thermal_temperature: thermal_zone=vpu0-thermal id=0 temp_prev=36986 temp=37979 [ 203.562845] thermal thermal_zone0: new temperature boundaries: 37000 < x < 40000 204.176059: thermal_temperature: thermal_zone=vpu0-thermal id=0 temp_prev=37979 temp=40028 [ 204.176089] thermal thermal_zone0: new temperature boundaries: 37000 < x < 100000 205.226813: thermal_temperature: thermal_zone=vpu0-thermal id=0 temp_prev=40028 temp=38652 [ 205.226842] thermal thermal_zone0: new temperature boundaries: 37000 < x < 40000 And with this patch applied: [ 184.933415] thermal thermal_zone0: new temperature boundaries: -2147483647 < x < 40000 185.981182: thermal_temperature: thermal_zone=vpu0-thermal id=0 temp_prev=36986 temp=37872 186.744685: thermal_temperature: thermal_zone=vpu0-thermal id=0 temp_prev=37872 temp=40058 [ 186.744716] thermal thermal_zone0: new temperature boundaries: 37000 < x < 100000 187.773284: thermal_temperature: thermal_zone=vpu0-thermal id=0 temp_prev=40058 temp=38698 Fixes: 060c034a9741 ("thermal: Add support for hardware-tracked trip points") Signed-off-by: Nícolas F.

2023-10-20efi/unaccepted: Fix soft lockups caused by parallel memory acceptanceKirill A. Shutemov
Michael reported soft lockups on a system that has unaccepted memory. This occurs when a user attempts to allocate and accept memory on multiple CPUs simultaneously. The root cause of the issue is that memory acceptance is serialized with a spinlock, allowing only one CPU to accept memory at a time. The other CPUs spin and wait for their turn, leading to starvation and soft lockup reports. To address this, the code has been modified to release the spinlock while accepting memory. This allows for parallel memory acceptance on multiple CPUs. A newly introduced "accepting_list" keeps track of which memory is currently being accepted. This is necessary to prevent parallel acceptance of the same memory block. If a collision occurs, the lock is released and the process is retried. Such collisions should rarely occur. The main path for memory acceptance is the page allocator, which accepts memory in MAX_ORDER chunks. As long as MAX_ORDER is equal to or larger than the unit_size, collisions will never occur because the caller fully owns the memory block being accepted. Aside from the page allocator, only memblock and deferered_free_range() accept memory, but this only happens during boot. The code has been tested with unit_size == 128MiB to trigger collisions and validate the retry codepath. Fixes: 2053bc57f367 ("efi: Add unaccepted memory support") Signed-off-by: Kirill A.

2023-10-20ixgbe: fix end of loop test in ixgbe_set_vf_macvlan()Dan Carpenter
The list iterator in a list_for_each_entry() loop can never be NULL. If the loop exits without hitting a break then the iterator points to an offset off the list head and dereferencing it is an out of bounds access. Before we transitioned to using list_for_each_entry() loops, then it was possible for "entry" to be NULL and the comments mention this. I have updated the comments to match the new code.

2023-10-20igb: Fix an end of loop testDan Carpenter
When we exit a list_for_each_entry() without hitting a break statement, the list iterator isn't NULL, it just point to an offset off the list_head. In that situation, it wouldn't be too surprising for entry->free to be true and we end up corrupting memory. The way to test for these is to just set a flag.

2023-10-20ice: cleanup ice_find_netlist_nodeJacob Keller
The ice_find_netlist_node function was introduced in commit 8a3a565ff210 ("ice: add admin commands to access cgu configuration"). Variations of this function were reviewed concurrently on both intel-wired-lan[1][2], and netdev [3][4] [1]: https://lore.kernel.org/intel-wired-lan/20230913204943.1051233-7-vadim.fedorenko@linux.dev/ [2]: https://lore.kernel.org/intel-wired-lan/20230817000058.2433236-5-jacob.e.keller@intel.com/ [3]: https://lore.kernel.org/netdev/20230918212814.435688-1-anthony.l.nguyen@intel.com/ [4]: https://lore.kernel.org/netdev/20230913204943.1051233-7-vadim.fedorenko@linux.dev/ The variant I posted had a few changes due to review feedback which were never incorporated into the DPLL series: * Replace the references to ancient and long removed ICE_SUCCESS and ICE_ERR_DOES_NOT_EXIST status codes in the function comment. * Return -ENOENT instead of -ENOTBLK, as a more common way to indicate that an entry doesn't exist. * Avoid the use of memset() and use simple static initialization for the cmd variable. * Use FIELD_PREP to assign the node_type_ctx. * Remove an unnecessary local variable to keep track of rec_node_handle, just pass the node_handle pointer directly into ice_aq_get_netlist_node.
