2021-11-20ethernet: renesas: Use div64_ul instead of do_divYang Li1-4/+2
do_div() does a 64-by-32 division. Here the divisor is an unsigned long which on some platforms is 64 bit wide. So use div64_ul instead of do_div to avoid a possible truncation. Eliminate the following coccicheck warning: ./drivers/net/ethernet/renesas/ravb_main.c:2492:1-7: WARNING: do_div() does a 64-by-32 division, please consider using div64_ul instead.

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memset(), avoid intentionally writing across neighboring fields.

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. Use struct_group() in struct nig_stats around members egress_mac_pkt0_lo, egress_mac_pkt0_hi, egress_mac_pkt1_lo, and egress_mac_pkt1_hi (and the respective members in struct bnx2x_eth_stats), so they can be referenced together. This will allow memcpy() and sizeof() to more easily reason about sizes, improve readability, and avoid future warnings about writing beyond the end of struct bnx2x_eth_stats's rx_stat_ifhcinbadoctets_hi. "pahole" shows no size nor member offset changes to either struct. "objdump -d" shows no meaningful object code changes (i.e. only source line number induced differences and optimizations). Additionally adds BUILD_BUG_ON() to compare the separate struct group sizes.

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull setattr idmapping fix from Christian Brauner: "This contains a simple fix for setattr. When determining the validity of the attributes the ia_{g,u}id fields contain the value that will be written to inode->i_{g,u}id. When the {g,u}id attribute of the file isn't altered and the caller's fs{g,u}id matches the current {g,u}id attribute the attribute change is allowed. The value in ia_{g,u}id does already account for idmapped mounts and will have taken the relevant idmapping into account. So in order to verify that the {g,u}id attribute isn't changed we simple need to compare the ia_{g,u}id value against the inode's i_{g,u}id value. This only has any meaning for idmapped mounts as idmapping helpers are idempotent without them. And for idmapped mounts this really only has a meaning when circular idmappings are used, i.e. mappings where e.g. id 1000 is mapped to id 1001 and id 1001 is mapped to id 1000. Such ciruclar mappings can e.g. be useful when sharing the same home directory between multiple users at the same time. Before this patch we could end up denying legitimate attribute changes and allowing invalid attribute changes when circular mappings are used. To even get into this situation the caller must've been privileged both to create that mapping and to create that idmapped mount. This hasn't been seen in the wild anywhere but came up when expanding the fstest suite during work on a series of hardening patches. All idmapped fstests pass without any regressions and we're adding new tests to verify the behavior of circular mappings.
