Subject: [PATCH] net: Refine key_len calculations in rhashtable_params
From: Liang Jie <liangjie@...iang.com>
This patch improves the calculation of key_len in the rhashtable_params
structures across the net driver modules by replacing hardcoded sizes
and previous calculations with appropriate macros like sizeof_field()
and offsetofend().
Previously, key_len was set using hardcoded sizes like sizeof(u32) or
sizeof(unsigned long), or using offsetof() calculations. This patch
replaces these with sizeof_field() and correct use of offsetofend(),
making the code more robust, maintainable, and improving readability.
Using sizeof_field() and offsetofend() provides several advantages:
- They explicitly specify the size of the field or the end offset of a
member being used as a key.
- They ensure that the key_len is accurate even if the structs change in
the future.
- They improve code readability by clearly indicating which fields are used
and how their sizes are determined, making the code easier to understand
and maintain.
For example, instead of:
.key_len = sizeof(u32),
we now use:
.key_len = sizeof_field(struct mae_mport_desc, mport_id),
And instead of:
.key_len = offsetof(struct efx_tc_encap_match, linkage),
we now use:
.key_len = offsetofend(struct efx_tc_encap_match, ip_tos_mask),
These changes eliminate the risk of including unintended padding or extra
data in the key, ensuring the rhashtable functions correctly.
