selftests: bpf: test_progs: initialize duration in singal_pending test
CHECK macro implicitly uses duration. We call CHECK() a couple of times
before duration is initialized from bpf_prog_test_run().
Explicitly set duration to 0 to avoid compiler warnings.

libbpf: force fixdep compilation at the start of the build
libbpf targets don't explicitly depend on fixdep target, so when we do 'make -j$(nproc)', there is a high probability, that some objects will be built before fixdep binary is available. Fix this by running sub-make; this makes sure that fixdep dependency is properly accounted for. For the same issue in perf, see commit |

selftests: bpf: fix compilation with out-of-tree $(OUTPUT)
A bunch of related changes lumped together:
* Create prog_tests and verifier output directories; these don't exist with
out-of-tree $(OUTPUT)
* Add missing -I (via separate TEST_{PROGS,VERIFIER}_CFLAGS) for the main tree
($(PWD) != $(OUTPUT) for out-of-tree)
* Add libbpf.a dependency for test_progs_32 (parallel make fails otherwise)
* Add missing "; \" after "cd" when generating test.h headers
Tested by:
$ alias m="make -s -j$(nproc)"
$ m -C tools/testing/selftests/bpf/ clean
$ m -C tools/lib/bpf/ clean
$ rm -rf xxx; mkdir xxx; m -C tools/testing/selftests/bpf/ OUTPUT=$PWD/xxx
$ m -C tools/testing/selftests/bpf/

selftests/bpf: test that GSO works in lwt_ip_encap
Add a test on egress that a large TCP packet successfully goes through the lwt+bpf encap tunnel. Although there is no direct evidence that GSO worked, as opposed to e.g. TCP segmentation or IP fragmentation (maybe a kernel stats counter should be added to track the number of failed GSO attempts?), without the previous patch in the patchset this test fails, and printk-debugging showed that software-based GSO succeeded here (veth is not compatible with SKB_GSO_DODGY, so GSO happens in the software stack). Also removed an unnecessary nodad and added a missed failed flag.

net: fix GSO in bpf_lwt_push_ip_encap
GSO needs inner headers and inner protocol set properly to work.
skb->inner_mac_header: skb_reset_inner_headers() assigns the current
mac header value to inner_mac_header; but it is not set at the point,
so we need to call skb_reset_inner_mac_header, otherwise gre_gso_segment
fails: it does
int tnl_hlen = skb_inner_mac_header(skb) - skb_transport_header(skb);
...
if (unlikely(!pskb_may_pull(skb, tnl_hlen)))
...
skb->inner_protocol should also be correctly set.

appletalk: Fix compile regression
A bugfix just broke compilation of appletalk when CONFIG_SYSCTL
is disabled:
In file included from net/appletalk/ddp.c:65:
net/appletalk/ddp.c: In function 'atalk_init':
include/linux/atalk.h:164:34: error: expected expression before 'do'
#define atalk_register_sysctl() do { } while(0)
^~
net/appletalk/ddp.c:1934:7: note: in expansion of macro 'atalk_register_sysctl'
rc = atalk_register_sysctl();
This is easier to avoid by using conventional inline functions
as stubs rather than macros. The header already has inline
functions for other purposes, so I'm changing over all the
macros for consistency.

I'm also seeing the same failure on x86_64, and it reproduces
consistently.
>From poking around it looks like the skb's dst entry is being used
to calculate the mtu in:
mtu = skb_dst(skb) ? dst_mtu(skb_dst(skb)) : dev->mtu;
...but because that dst_entry has an "ops" value set to md_dst_ops,
the various ops (including mtu) are not set:
crash> struct sk_buff._skb_refdst ffff928f87447700 -x
_skb_refdst = 0xffffcd6fbf5ea590
crash> struct dst_entry.ops 0xffffcd6fbf5ea590
ops = 0xffffffffa0193800
crash> struct dst_ops.mtu 0xffffffffa0193800
mtu = 0x0
crash>
I confirmed that the dst entry also has dst->input set to
dst_md_discard, so it looks like it's an entry that's been
initialized via __metadata_dst_init alright.
I think the fix here is to use skb_valid_dst(skb) - it checks
for DST_METADATA also, and with that fix in place, the
problem - which was previously 100% reproducible - disappears.
The below patch resolves the panic and all bpf tunnel tests pass
without incident.

ipv4/route: fail early when inet dev is missing
If a non local multicast packet reaches ip_route_input_rcu() while
the ingress device IPv4 private data (in_dev) is NULL, we end up
doing a NULL pointer dereference in IN_DEV_MFORWARD().
Since the later call to ip_route_input_mc() is going to fail if
!in_dev, we can fail early in such scenario and avoid the dangerous
code path.

x86: Deprecate a.out support
Linux supports ELF binaries for ~25 years now. a.out coredumping has bitrotten quite significantly and would need some fixing to get it into shape again but considering how even the toolchains cannot create a.out executables in its default configuration, let's deprecate a.out support and remove it a couple of releases later, instead.

a.out: remove core dumping support
We're (finally) phasing out a.out support for good. As Borislav Petkov points out, we've supported ELF binaries for about 25 years by now, and coredumping in particular has bitrotted over the years. None of the tool chains even support generating a.out binaries any more, and the plan is to deprecate a.out support entirely for the kernel. But I want to start with just removing the core dumping code, because I can still imagine that somebody actually might want to support a.out as a simpler biinary format. Particularly if you generate some random binaries on the fly, ELF is a much more complicated format (admittedly ELF also does have a lot of toolchain support, mitigating that complexity a lot and you really should have moved over in the last 25 years). So it's at least somewhat possible that somebody out there has some workflow that still involves generating and running a.out executables. In contrast, it's very unlikely that anybody depends on debugging any legacy a.out core files. But regardless, I want this phase-out to be done in two steps, so that we can resurrect a.out support (if needed) without having to resurrect the core file dumping that is almost certainly not needed. Jann Horn pointed to the <asm/a.out-core.h> file that my first trivial cut at this had missed. And Alan Cox points out that the a.out binary loader _could_ be done in user space if somebody wants to, but we might keep just the loader in the kernel if somebody really wants it, since the loader isn't that big and has no really odd special cases like the core dumping does.

spi: Updates for v5.1
A fairly quiet release for SPI, the biggest thing is the conversion to
use GPIO descriptors which is now 90% done but still needs some
stragglers converting.
- Support for inter-word delays.
- Conversion of the core and most drivers to use GPIO descriptors for
GPIO controlled chip selects.
- New drivers for NXP FlexSPI and QuadSPI, SiFive and Spreadtrum.

regulator: Updates for v5.1
The bulk of the standout changes in this release are cleanups, with the
core work being a combination of factoring out common code into helpers
and the completion of the conversion of the core to use GPIO
descriptors.
- Addition of helper functions for current limits and conversion of
drivers to use them by Axel Lin.
- Lots and lots of cleanups from Axel Lin.
- Conversion of the core to use GPIO descriptors rather than numbers by
Linus Walleij.
- New drivers for Maxim MAX77650 and ROHM BD70528.

regmap: Changes for v5.1
There's only two changes here, one fix for conflicting attributes on the
rbtree node structure and the implementation of main status register
support in the interrupt code which supports chips that have a register
to cut down on the number of per-interrupt status registers that need to
be checked when handling interrupts.

fs: Make splice() and tee() take into account O_NONBLOCK flag on pipes
The current implementation of splice() and tee() ignores O_NONBLOCK set
on pipe file descriptors and checks only the SPLICE_F_NONBLOCK flag for
blocking on pipe arguments. This is inconsistent since splice()-ing
from/to non-pipe file descriptors does take O_NONBLOCK into
consideration.
Fix this by promoting O_NONBLOCK, when set on a pipe, to
SPLICE_F_NONBLOCK.
Some context for how the current implementation of splice() leads to
inconsistent behavior. In the ongoing work[1] to add VM tracing
capability to trace-cmd we stream tracing data over named FIFOs or
vsockets from guests back to the host.
When we receive SIGINT from user to stop tracing, we set O_NONBLOCK on
the input file descriptor and set SPLICE_F_NONBLOCK for the next call to
splice(). If splice() was blocked waiting on data from the input FIFO,
after SIGINT splice() restarts with the same arguments (no
SPLICE_F_NONBLOCK) and blocks again instead of returning -EAGAIN when no
data is available.
This differs from the splice() behavior when reading from a vsocket or
when we're doing a traditional read()/write() loop (trace-cmd's
--nosplice argument).
With this patch applied we get the same behavior in all situations after
setting O_NONBLOCK which also matches the behavior of doing a
read()/write() loop instead of splice().
This change does have potential of breaking users who don't expect
EAGAIN from splice() when SPLICE_F_NONBLOCK is not set. OTOH programs
that set O_NONBLOCK and don't anticipate EAGAIN are arguably buggy[2].

sky2: Disable MSI on Dell Inspiron 1545 and Gateway P-79
Some sky2 chips fire IRQ after S3, before the driver is fully resumed: [ 686.804877] do_IRQ: 1.37 No irq handler for vector This is likely a platform bug that device isn't fully quiesced during S3. Use MSI-X, maskable MSI or INTx can prevent this issue from happening. Since MSI-X and maskable MSI are not supported by this device, fallback to use INTx on affected platforms.

net/mlx5e: Update tx reporter status in case channels were successfully opened
Once channels were successfully opened, update tx reporter health state to healthy. This is needed for the following scenario: - SQ has an un-recovered error reported to the devlink health, resulting tx reporter state to be error. - Current channels (including this SQ) are closed - New channels are opened After that flow, the original error was "solved", and tx reporter state should be healthy. However, as it was resolved as a side effect, and not via tx reporter recover method, driver needs to inform devlink health about it.

devlink: Add support for direct reporter health state update
It is possible that a reporter state will be updated due to a recover flow which is not triggered by a devlink health related operation, but as a side effect of some other operation in the system. Expose devlink health API for a direct update of a reporter status. Move devlink_health_reporter_state enum definition to devlink.h so it could be used from drivers as a parameter of devlink_health_reporter_state_update. In addition, add trace_devlink_health_reporter_state_update to provide user notification for reporter state change.

devlink: Update reporter state to error even if recover aborted
If devlink_health_report() aborted the recover flow due to grace period checker,
it left the reporter status as DEVLINK_HEALTH_REPORTER_STATE_HEALTHY, which is
a bug. Fix that by always setting the reporter state to
DEVLINK_HEALTH_REPORTER_STATE_ERROR prior to running the checker mentioned above.
In addition, save the previous health_state in a temporary variable, then use
it in the abort check comparison instead of using reporter->health_state which
might be already changed.

sctp: call iov_iter_revert() after sending ABORT
The user msg is also copied to the abort packet when doing SCTP_ABORT in
sctp_sendmsg_check_sflags(). When SCTP_SENDALL is set, iov_iter_revert()
should have been called for sending abort on the next asoc with copying
this msg. Otherwise, memcpy_from_msg() in sctp_make_abort_user() will
fail and return error.
