If the driver would like to transmit a jumbo frame like 2KiB or more, it should be split into multiple queues. In the near future, to support this, add unmap_addrs array to unmap dma mapping address instead of dma address in each TX descriptor because the descriptors may not have the top dma address.

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 expect mdiodev->modalias to be NUL-terminated based on its usage with strcmp(): | return strcmp(mdiodev->modalias, drv->name) == 0; Moreover, mdiodev->modalias is already zero-allocated: | mdiodev = kzalloc(sizeof(*mdiodev), GFP_KERNEL); ... which means the NUL-padding strncpy provides is not necessary. 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.

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 expect fw_info->fw_file_name to be NUL-terminated based on its use within _request_firmware_prepare() wherein `name` refers to it: | if (firmware_request_builtin_buf(firmware, name, dbuf, size)) { | dev_dbg(device, "using built-in %s\n", name); | return 0; /* assigned */ | } ... and with firmware_request_builtin() also via `name`: | if (strcmp(name, b_fw->name) == 0) { There is no evidence that NUL-padding is required. Additionally replace size macro (QLC_FW_FILE_NAME_LEN) with sizeof(fw_info->fw_file_name) to more directly tie the maximum buffer size to the destination buffer: 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.

However zero initialization of the destination doesn't matter in this case, because strscpy() guarantees a NULL termination.

My prior patch went a bit too far, because apparently fib6_has_expires() could be true while f6i->gc_link is not hashed yet. fib6_set_expires_locked() can indeed set RTF_EXPIRES while f6i->fib6_table is NULL. Original syzbot reports were about corruptions caused by dangling f6i->gc_link.

The return value from nla_len() is never expected to be negative, and can never be more than struct nlattr::nla_len (a u16). Adjust the prototype on the function. This will let GCC's value range optimization passes know that the return can never be negative, and can never be larger than u16. As recently discussed[1], this silences the following warning in GCC 12+: net/wireless/nl80211.c: In function 'nl80211_set_cqm_rssi.isra': net/wireless/nl80211.c:12892:17: warning: 'memcpy' specified bound 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Wstringop-overflow=] 12892 | memcpy(cqm_config->rssi_thresholds, thresholds, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 12893 | flex_array_size(cqm_config, rssi_thresholds, | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 12894 | n_thresholds)); | ~~~~~~~~~~~~~~ A future change would be to clamp the subtraction to make sure it never wraps around if nla_len is somehow less than NLA_HDRLEN, which would have the additional benefit of being defensive in the face of nlattr corruption or logic errors.

Commit 227b60f5 added a seqlock to ensure that the low and high port numbers were always updated together. This is overkill because the two 16bit port numbers can be held in a u32 and read/written in a single instruction. More recently 91d0b78c added support for finer per-socket limits. The user-supplied value is 'high << 16 | low' but they are held separately and the socket options protected by the socket lock. Use a u32 containing 'high << 16 | low' for both the 'net' and 'sk' fields and use READ_ONCE()/WRITE_ONCE() to ensure both values are always updated together. Change (the now trival) inet_get_local_port_range() to a static inline to optimise the calling code. (In particular avoiding returning integers by reference.) Signed-off-by:

Justin Stitt says: ==================== ethtool: Add ethtool_puts() This series aims to implement ethtool_puts() and send out a wave 1 of conversions from ethtool_sprintf(). There's also a checkpatch patch included to check for the cases listed below. This was sparked from recent discussion here [1] The conversions are used in cases where ethtool_sprintf() was being used with just two arguments: | ethtool_sprintf(&data, buffer[i].name); or when it's used with format string: "%s" | ethtool_sprintf(&data, "%s", buffer[i].name); which both now become: | ethtool_puts(&data, buffer[i].name); The first case commonly triggers a -Wformat-security warning with Clang due to potential problems with format flags present in the strings [3]. The second is just a bit weird with a plain-ol' "%s". Changes found with Cocci [4] and grep [5].

Add some warnings for using ethtool_sprintf() where a simple ethtool_puts() would suffice. The two cases are: 1) Use ethtool_sprintf() with just two arguments: | ethtool_sprintf(&data, driver[i].name); or 2) Use ethtool_sprintf() with a standalone "%s" fmt string: | ethtool_sprintf(&data, "%s", driver[i].name); The former may cause -Wformat-security warnings while the latter is just not preferred. Both are safely in the category of warnings, not errors. Signed-off-by:

After backporting commit 581512a6 ("vsock/virtio: MSG_ZEROCOPY flag support") in CentOS Stream 9, CI reported the following error: In file included from ./include/linux/kernel.h:17, from ./include/linux/list.h:9, from ./include/linux/preempt.h:11, from ./include/linux/spinlock.h:56, from net/vmw_vsock/virtio_transport_common.c:9: net/vmw_vsock/virtio_transport_common.c: In function ‘virtio_transport_can_zcopy‘: ./include/linux/minmax.h:20:35: error: comparison of distinct pointer types lacks a cast [-Werror] 20 | (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1))) | ^~ ./include/linux/minmax.h:26:18: note: in expansion of macro ‘__typecheck‘ 26 | (__typecheck(x, y) && __no_side_effects(x, y)) | ^~~~~~~~~~~ ./include/linux/minmax.h:36:31: note: in expansion of macro ‘__safe_cmp‘ 36 | __builtin_choose_expr(__safe_cmp(x, y), \ | ^~~~~~~~~~ ./include/linux/minmax.h:45:25: note: in expansion of macro ‘__careful_cmp‘ 45 | #define min(x, y) __careful_cmp(x, y, <) | ^~~~~~~~~~~~~ net/vmw_vsock/virtio_transport_common.c:63:37: note: in expansion of macro ‘min‘ 63 | int pages_to_send = min(pages_in_iov, MAX_SKB_FRAGS); We could solve it by using min_t(), but this operation seems entirely unnecessary, because we also pass MAX_SKB_FRAGS to iov_iter_npages(), which performs almost the same check, returning at most MAX_SKB_FRAGS elements. So, let's eliminate this unnecessary comparison. Fixes: 581512a6 ("vsock/virtio: MSG_ZEROCOPY flag support") Cc: avkrasnov@salutedevices.com Signed-off-by:
