| H A D | sysctl.h | diff 32927393 Fri Apr 24 00:43:38 MDT 2020 Christoph Hellwig <hch@lst.de> sysctl: pass kernel pointers to ->proc_handler Instead of having all the sysctl handlers deal with user pointers, which is rather hairy in terms of the BPF interaction, copy the input to and from userspace in common code. This also means that the strings are always NUL-terminated by the common code, making the API a little bit safer. As most handler just pass through the data to one of the common handlers a lot of the changes are mechnical.
