2024-11-05sysfs: treewide: constify attribute callback of bin_is_visible()Thomas Weißschuh
The is_bin_visible() callbacks should not modify the struct bin_attribute passed as argument. Enforce this by marking the argument as const. As there are not many callback implementers perform this change throughout the tree at once. Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> Acked-by: Martin K.

2024-09-10IB/qib: Remove unused declarations in header fileZhang Zekun
The definition of qib_rc_rnr_retry() has been removed since commit b4238e70579c ("IB/qib: Use new rdmavt timers"). Also, the definition of mr_rcu_callback() has been remove since commit 7c2e11fe2dbe ("IB/qib: Remove qp and mr functionality from qib"). So, let's remove the unused declartions.

2023-09-22IB/qib: Replace deprecated strncpyJustin 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 `txselect_list` is expected to be NUL-terminated based on its use in `param_get_string()`: | int param_get_string(char *buffer, const struct kernel_param *kp) | { | const struct kparam_string *kps = kp->str; | return scnprintf(buffer, PAGE_SIZE, "%s\n", kps->string); | } Note that `txselect_list` is assigned to `kp_txselect`'s string field: | static struct kparam_string kp_txselect = { | .string = txselect_list, | .maxlen = MAX_ATTEN_LEN | }; Wherein it is then assigned the set and get methods: | module_param_call(txselect, setup_txselect, param_get_string, | &kp_txselect, S_IWUSR | S_IRUGO); 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.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the large set of driver core changes for 6.4-rc1. Once again, a busy development cycle, with lots of changes happening in the driver core in the quest to be able to move "struct bus" and "struct class" into read-only memory, a task now complete with these changes. This will make the future rust interactions with the driver core more "provably correct" as well as providing more obvious lifetime rules for all busses and classes in the kernel. The changes required for this did touch many individual classes and busses as many callbacks were changed to take const * parameters instead. All of these changes have been submitted to the various subsystem maintainers, giving them plenty of time to review, and most of them actually did so. Other than those changes, included in here are a small set of other things: - kobject logging improvements - cacheinfo improvements and updates - obligatory fw_devlink updates and fixes - documentation updates - device property cleanups and const * changes - firwmare loader dependency fixes.

2023-03-30IB/qib: check for user backed iterator, not specific iterator typeJens Axboe
In preparation for switching single segment iterators to using ITER_UBUF, swap the check for whether we are user backed or not. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2023-03-30iov_iter: add iter_iovec() helperJens Axboe
This returns a pointer to the current iovec entry in the iterator. Only useful with ITER_IOVEC right now, but it prepares us to treat ITER_UBUF and ITER_IOVEC identically for the first segment. Rename struct iov_iter->iov to iov_iter->__iov to find any potentially troublesome spots, and also to prevent anyone from adding new code that accesses iter->iov directly.

2023-03-19IB/qib: Drop redundant pci_enable_pcie_error_reporting()Bjorn Helgaas
pci_enable_pcie_error_reporting() enables the device to send ERR_* Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"), the PCI core does this for all devices during enumeration, so the driver doesn't need to do it itself. Remove the redundant pci_enable_pcie_error_reporting() call from the driver. Note that this only controls ERR_* Messages from the device. An ERR_* Message may cause the Root Port to generate an interrupt, depending on the AER Root Error Command register managed by the AER service driver.

2023-03-19RDMA/qib: Remove deprecated kmap() callIra Weiny
kmap() has been deprecated in favor of the kmap_local_page() call. kmap_local_page() is thread local. In the sdma coalesce case the page allocated is potentially free'ed in a different context through qib_sdma_get_complete() -> qib_user_sdma_make_progress(). The use of kmap_local_page() is inappropriate in this call path. However, the page is allocated using GFP_KERNEL and will never be from highmem. Remove the use of kmap calls and use page_address() in this case.
