[PATCH v3 00/17] netfilter: Create new type for kernel pointers.

by Joshua Lant

Changes from v2: - [01/17] Updated first commit comment to make more sense to the reader. - [XX/17] Numerous formatting nits fixed. - [05/17] Fixed up local assignment and functional regression found. - [08/17] Fixed up functional regression found. Requested changes not addressed: In patch [01/17]: > Do we really have to duplicate the typedefs here? There are already > quite a few headers including <linux/netfilter.h> under > include/uapi/linux/netfilter/ so including it in x_tables.h too > shouldn't be too problematic. Unfortunately this duplication is required. I encountered many issues building when I tried this initially before the last patch submission. Presumably this is an artefact of xtables being deprecated by nftables? Many definitions are duplicated between these two headers.

[PATCH v2 00/17] netfilter: remove kernel pointers from uapi structs

by Joshua Lant

This is v2 of the previous patchset found here: https://op-lists.linaro.org/archives/list/linux-morello@op-lists.linaro.org… I have added the new __nf_kptr_t type and modified all the patches accordingly, as well as fixing up all (hopefully) of the nits found in the previous patches. Many thanks Kevin for your input on everything. I hope that this is now in a decent state. Cheers.
