The change of sizeof(struct smc_diag_linkinfo) by commit 79d39fc503
("net/smc: Add netlink net namespace support") introduced an ABI
regression: since struct smc_diag_lgrinfo contains an object of
type "struct smc_diag_linkinfo", offset of all subsequent members
of struct smc_diag_lgrinfo was changed by that change.
As result, applications compiled with the old version
of struct smc_diag_linkinfo will receive garbage in
struct smc_diag_lgrinfo.role if the kernel implements
this new version of struct smc_diag_linkinfo.
Fix this regression by reverting the part of commit 79d39fc503 that
changes struct smc_diag_linkinfo. After all, there is SMC_GEN_NETLINK
interface which is good enough, so there is probably no need to touch
the smc_diag ABI in the first place.

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 vlan_ethhdr around members h_dest and
h_source, 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 h_dest.

max_average_bw is calculated as `ceil / BYTES_IN_MBIT`, which can become

When packet_setsockopt( PACKET_FANOUT_DATA ) reads po->fanout,
no lock is held, meaning that another thread can change po->fanout.
Given that po->fanout can only be set once during the socket lifetime
(it is only cleared from fanout_release()), we can use
READ_ONCE()/WRITE_ONCE() to document the race.

While looking at one unrelated syzbot bug, I found the replay logic

It is better to clear master_dev and m_ops inside the loop,

When cross-building tools with clang, we run `which $(CROSS_COMPILE)gcc`
to detect whether a GCC toolchain provides the standard libraries. It is
only a helper because some distros put libraries where LLVM does not
automatically find them. On other systems, LLVM detects the libc
automatically and does not need this. There, it is completely fine not
to have a GCC at all, but some versions of `which' display an error when
the command is not found:
which: no aarch64-linux-gnu-gcc in ($PATH)
Since the error can safely be ignored, throw it to /dev/null.

Lenovo AMD based platforms have been offering platform_profiles but they
are not working correctly. This is because the mode we are using on the
Intel platforms (MMC) is not available on the AMD platforms.
This commit adds checking of the functional capabilities returned by the
BIOS to confirm if MMC is supported or not. Profiles will not be
available if the platform is not MMC capable.
I'm investigating and working on an alternative for AMD platforms but
that is still work-in-progress.

This code calls fd_install() which gives the userspace access to the fd.
Then if copy_info_records_to_user() fails it calls put_unused_fd(fd) but
that will not release it and leads to a stale entry in the file
descriptor table.
Generally you can't trust the fd after a call to fd_install(). The fix
is to delay the fd_install() until everything else has succeeded.
Fortunately it requires CAP_SYS_ADMIN to reach this code so the security
impact is less.
