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. Reviewed-by:

We always need an RX queue, and there's no reconfig situation either where we would need to free & rebuild the queue. So allocate the RX queue right from the start, and avoid freeing it during unrelated qeth_free_qdio_queues() calls. Signed-off-by:

Jakub Kicinski says: ==================== net: use eth_hw_addr_set() in arch-specific drivers Fixups for more arch-specific drivers. With these (and another patch which didn't fit) the build is more or less clean with all cross-compilers available on kernel.org. I say more or less because around half of the arches fail to build for unrelated reasons right now. Most of the changes here are for m68k, 32bit x86 and alpha. ==================== Signed-off-by: -

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. The new tests can be found at [1]" Link: https://lore.kernel.org/linux-fsdevel/20211109145713.1868404-2-brauner@kernel.org [1] * tag 'fs.idmapped.v5.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: fs: handle circular mappings correctly -
