Masahiro Yamada d188b8c901 kbuild: update compile-test header list for v5.4-rc2
Commit 6dc280ebee ("coda: remove uapi/linux/coda_psdev.h") removed
a header in question. Some more build errors were fixed. Add more
headers into the test coverage.

Linus Torvalds 02dc96ef6c Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from David Miller:

 1) Sanity check URB networking device parameters to avoid divide by
    zero, from Oliver Neukum.

 2) Disable global multicast filter in NCSI, otherwise LLDP and IPV6
    don't work properly. Longer term this needs a better fix tho. From
    Vijay Khemka.

 3) Small fixes to selftests (use ping when ping6 is not present, etc.)
    from David Ahern.

 4) Bring back rt_uses_gateway member of struct rtable, it's semantics
    were not well understood and trying to remove it broke things. From
    David Ahern.

 5) Move usbnet snaity checking, ignore endpoints with invalid
    wMaxPacketSize. From Bjørn Mork.

 6) Missing Kconfig deps for sja1105 driver, from Mao Wenan.

 7) Various small fixes to the mlx5 DR steering code, from Alaa Hleihel,
    Alex Vesker, and Yevgeny Kliteynik

 8) Missing CAP_NET_RAW checks in various places, from Ori Nimron.

 9) Fix crash when removing sch_cbs entry while offloading is enabled,
    from Vinicius Costa Gomes.

10) Signedness bug fixes, generally in looking at the result given by
    of_get_phy_mode() and friends. From Dan Crapenter.

11) Disable preemption around BPF_PROG_RUN() calls, from Eric Dumazet.

12) Don't create VRF ipv6 rules if ipv6 is disabled, from David Ahern.

13) Fix quantization code in tcp_bbr, from Kevin Yang.

Masahiro Yamada 20ff1cb506 netfilter: ebtables: use __u8 instead of uint8_t in uapi header
When CONFIG_UAPI_HEADER_TEST=y, exported headers are compile-tested to
make sure they can be included from user-space.

Currently, linux/netfilter_bridge/ebtables.h is excluded from the test
coverage. To make it join the compile-test, we need to fix the build
errors attached below.

For a case like this, we decided to use __u{8,16,32,64} variable types
in this discussion:

Masahiro Yamada 1634f2bfdb kbuild: remove clean-dirs syntax
The only the difference between clean-files and clean-dirs is the -r
option passed to the 'rm' command.

You can always pass -r, and then remove the clean-dirs syntax.

Heiko Carstens a963609e27 kbuild: enable arch/s390/include/uapi/asm/zcrypt.h for uapi header test
Masahiro Yamada changed the zcrypt.h header file to use __u{16,32,64}
instead of uint{16,32,64}_t with ("s390: use __u{16,32,64} instead of
uint{16,32,64}_t in uapi header").

This makes all s390 header files pass - remove zcrypt.h from the blacklist.

Masahiro Yamada 67bf47452e kbuild: update compile-test header list for v5.3-rc1
- Some headers graduated from the blacklist

 - hyperv_timer.h joined the header-test when CONFIG_X86=y

 - nf_tables*.h joined the header-test when CONFIG_NF_TABLES is
   enabled.

 - The entry for nf_tables_offload.h was added to fix build error for
   the combination of CONFIG_NF_TABLES=n and CONFIG_KERNEL_HEADER_TEST=y.

 - The entry for iomap.h was added because this header is supposed to
   be included only when CONFIG_BLOCK=y

Masahiro Yamada d6fc9fcbaa kbuild: compile-test exported headers to ensure they are self-contained
Multiple people have suggested compile-testing UAPI headers to ensure
they can be really included from user-space. "make headers_check" is
obviously not enough to catch bugs, and we often leak unresolved
references to user-space.

Use the new header-test-y syntax to implement it. Please note exported
headers are compile-tested with a completely different set of compiler
flags. The header search path is set to $(objtree)/usr/include since
exported headers should not include unexported ones.

We use -std=gnu89 for the kernel space since the kernel code highly
depends on GNU extensions. On the other hand, UAPI headers should be
written in more standardized C, so they are compiled with -std=c90.
This will emit errors if C++ style comments, the keyword 'inline', etc.
are used. Please use C style comments (/* ... */), '__inline__', etc.
in UAPI headers.

There is additional compiler requirement to enable this test because
many of UAPI headers include <stdlib.h>, <sys/ioctl.h>, <sys/time.h>,
etc. directly or indirectly. You cannot use kernel.org pre-built
toolchains [1] since they lack <stdlib.h>.

I reused CONFIG_CC_CAN_LINK to check the system header availability.
The intention is slightly different, but a compiler that can link
userspace programs provide system headers.

For now, a lot of headers need to be excluded because they cannot
be compiled standalone, but this is a good start point.
