0529883ad1 selftests: forwarding: Switch off timeout
The default timeout for selftests is 45 seconds, but it is not enough
for forwarding selftests which can takes minutes to finish depending on
the number of tests cases:

 # make -C tools/testing/selftests TARGETS=net/forwarding run_tests
 TAP version 13
 1..102
 # timeout set to 45
 # selftests: net/forwarding: bridge_igmp.sh
 # TEST: IGMPv2 report 239.10.10.10                                    [ OK ]
 # TEST: IGMPv2 leave 239.10.10.10                                     [ OK ]
 # TEST: IGMPv3 report 239.10.10.10 is_include                         [ OK ]
 # TEST: IGMPv3 report 239.10.10.10 include -> allow                   [ OK ]
 #
 not ok 1 selftests: net/forwarding: bridge_igmp.sh # TIMEOUT 45 seconds

Fix by switching off the timeout and setting it to 0. A similar change
was done for BPF selftests in commit 6fc5916cc2 ("selftests: bpf:
Switch off timeout").

d72c83b1e4 selftests: forwarding: Skip test when no interfaces are specified
As explained in [1], the forwarding selftests are meant to be run with
either physical loopbacks or veth pairs. The interfaces are expected to
be specified in a user-provided forwarding.config file or as command
line arguments. By default, this file is not present and the tests fail:

 # make -C tools/testing/selftests TARGETS=net/forwarding run_tests
 [...]
 TAP version 13
 1..102
 # timeout set to 45
 # selftests: net/forwarding: bridge_igmp.sh
 # Command line is not complete. Try option "help"
 # Failed to create netif
 not ok 1 selftests: net/forwarding: bridge_igmp.sh # exit=1
 [...]

Fix by skipping a test if interfaces are not provided either via the
configuration file or command line arguments.

 # make -C tools/testing/selftests TARGETS=net/forwarding run_tests
 [...]
 TAP version 13
 1..102
 # timeout set to 45
 # selftests: net/forwarding: bridge_igmp.sh
 # SKIP: Cannot create interface. Name not specified

8743aeff5b nexthop: Fix infinite nexthop bucket dump when using maximum nexthop ID
A netlink dump callback can return a positive number to signal that more
information needs to be dumped or zero to signal that the dump is
complete. In the second case, the core netlink code will append the
NLMSG_DONE message to the skb in order to indicate to user space that
the dump is complete.

The nexthop bucket dump callback always returns a positive number if
nexthop buckets were filled in the provided skb, even if the dump is
complete. This means that a dump will span at least two recvmsg() calls
as long as nexthop buckets are present. In the last recvmsg() call the
dump callback will not fill in any nexthop buckets because the previous
call indicated that the dump should restart from the last dumped nexthop
ID plus one.

 # ip link add name dummy1 up type dummy
 # ip nexthop add id 1 dev dummy1
 # ip nexthop add id 10 group 1 type resilient buckets 2
 # strace -e sendto,recvmsg -s 5 ip nexthop bucket
 sendto(3, [[{nlmsg_len=24, nlmsg_type=RTM_GETNEXTHOPBUCKET, nlmsg_flags=NLM_F_REQUEST|NLM_F_DUMP, nlmsg_seq=1691396980, nlmsg_pid=0}, {family=AF_UNSPEC, data="\x00\x00\x00\x00\x00"...}], {nlmsg_len=0, nlmsg_type=0 /* NLMSG_??? */, nlmsg_flags=0, nlmsg_seq=0, nlmsg_pid=0}], 152, 0, NULL, 0) = 152

 +++ exited with 0 +++

This behavior is both inefficient and buggy. If the last nexthop to be
dumped had the maximum ID of 0xffffffff, then the dump will restart from
0 (0xffffffff + 1) and never end:

 # ip link add name dummy1 up type dummy
 # ip nexthop add id 1 dev dummy1
 # ip nexthop add id $((2**32-1)) group 1 type resilient buckets 2
 # ip nexthop bucket
 id 4294967295 index 0 idle_time 5.55 nhid 1

 id 4294967295 index 0 idle_time 5.55 nhid 1
 id 4294967295 index 1 idle_time 5.55 nhid 1
 [...]

Fix by adjusting the dump callback to return zero when the dump is
complete. After the fix only one recvmsg() call is made and the
NLMSG_DONE message is appended to the RTM_NEWNEXTHOPBUCKET responses:

 # ip link add name dummy1 up type dummy
 # ip nexthop add id 1 dev dummy1
 # ip nexthop add id $((2**32-1)) group 1 type resilient buckets 2

 +++ exited with 0 +++

Note that if the NLMSG_DONE message cannot be appended because of size
limitations, then another recvmsg() will be needed, but the core netlink
code will not invoke the dump callback and simply reply with a
NLMSG_DONE message since it knows that the callback previously returned
zero.

Add a test that fails before the fix:

 # ./fib_nexthops.sh -t basic_res
 [...]
 TEST: Maximum nexthop ID dump                                       [FAIL]

mptcp_join 'implicit EP' test currently fails when using ip mptcp:

This happens because of two reasons:
- iproute v6.3.0 does not support the implicit flag, fixed with
  iproute2-next commit 3a2535a41854 ("mptcp: add support for implicit
  flag")
- pm_nl_check_endpoint wrongly expects the ip address to be repeated two
  times in iproute output, and does not account for a final whitespace
  in it.

This fixes the issue trimming the whitespace in the output string and
removing the double address in the expected string.

This happens because endpoint delete includes an ip address while id is
not 0, contrary to what is indicated in the ip mptcp man page:

"When used with the delete id operation, an IFADDR is only included when
the ID is 0."

This fixes the issue using the $addr variable in pm_nl_del_endpoint()
only when id is 0.

TCP might get stuck if a nonlinear skb exceeds the path MTU,
icmp error contains an incorrect icmp checksum in that case.

Extend the existing test for vxlan to also send at least 1MB worth of
data via TCP in addition to the existing 'large icmp packet adds
route exception'.

On my test VM this fails due to 0-size output file without

Nothing scary here. Feels like the first wave of regressions
 from v6.5 is addressed - one outstanding fix still to come
 in TLS for the sendpage rework.
 
 Current release - regressions:
 
  - udp: fix __ip_append_data()'s handling of MSG_SPLICE_PAGES
 
  - dsa: fix older DSA drivers using phylink
 
 Previous releases - regressions:
 
  - gro: fix misuse of CB in udp socket lookup
 
  - mlx5: unregister devlink params in case interface is down
 
  - Revert "wifi: ath11k: Enable threaded NAPI"
 
 Previous releases - always broken:
 
  - sched: cls_u32: fix match key mis-addressing
 
  - sched: bind logic fixes for cls_fw, cls_u32 and cls_route
 
  - add bound checks to a number of places which hand-parse netlink
 
  - bpf: disable preemption in perf_event_output helpers code
 
  - qed: fix scheduling in a tasklet while getting stats
 
  - avoid using APIs which are not hardirq-safe in couple of drivers,
    when we may be in a hard IRQ (netconsole)
 
  - wifi: cfg80211: fix return value in scan logic, avoid page
    allocator warning

Merge tag 'net-6.5-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bpf and wireless.

  Nothing scary here. Feels like the first wave of regressions from v6.5
  is addressed - one outstanding fix still to come in TLS for the
  sendpage rework.

  Current release - regressions:

   - udp: fix __ip_append_data()'s handling of MSG_SPLICE_PAGES

   - dsa: fix older DSA drivers using phylink

  Previous releases - regressions:

   - gro: fix misuse of CB in udp socket lookup

   - mlx5: unregister devlink params in case interface is down

   - Revert "wifi: ath11k: Enable threaded NAPI"

  Previous releases - always broken:

   - sched: cls_u32: fix match key mis-addressing

   - sched: bind logic fixes for cls_fw, cls_u32 and cls_route

   - add bound checks to a number of places which hand-parse netlink

   - bpf: disable preemption in perf_event_output helpers code

   - qed: fix scheduling in a tasklet while getting stats

   - avoid using APIs which are not hardirq-safe in couple of drivers,
     when we may be in a hard IRQ (netconsole)

   - wifi: cfg80211: fix return value in scan logic, avoid page
     allocator warning

   - wifi: mt76: mt7615: do not advertise 5 GHz on first PHY of MT7615D
     (DBDC)

  Misc:

   - drop handful of inactive maintainers, put some new in place"

Dan Carpenter reported an error spotted by Smatch.

  error: uninitialized symbol 'ret'.

The returned value of sched_setaffinity() should be checked with
ASSERT_EQ(), but the value was not saved in a proper variable,
resulting in an error above.

e739718444 net/sched: taprio: Limit TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME to INT_MAX.
syzkaller found zero division error [0] in div_s64_rem() called from
get_cycle_time_elapsed(), where sched->cycle_time is the divisor.

We have tests in parse_taprio_schedule() so that cycle_time will never
be 0, and actually cycle_time is not 0 in get_cycle_time_elapsed().

The problem is that the types of divisor are different; cycle_time is
s64, but the argument of div_s64_rem() is s32.

syzkaller fed this input and 0x100000000 is cast to s32 to be 0.

  @TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME={0xc, 0x8, 0x100000000}

We use s64 for cycle_time to cast it to ktime_t, so let's keep it and
set max for cycle_time.

While at it, we prevent overflow in setup_txtime() and add another
test in parse_taprio_schedule() to check if cycle_time overflows.

Also, we add a new tdc test case for this issue.

5a7591176c KVM: selftests: Expand x86's sregs test to cover illegal CR0 values
Add coverage to x86's set_sregs_test to verify KVM rejects vendor-agnostic
illegal CR0 values, i.e. CR0 values whose legality doesn't depend on the
current VMX mode.  KVM historically has neglected to reject bad CR0s from
userspace, i.e. would happily accept a completely bogus CR0 via
KVM_SET_SREGS{2}.

Punt VMX specific subtests to future work, as they would require quite a
bit more effort, and KVM gets coverage for CR0 checks in general through
other means, e.g. KVM-Unit-Tests.

65f1f57f35 KVM: selftests: Verify stats fd can be dup()'d and read
Expand the binary stats test to verify that a stats fd can be dup()'d
and read, to (very) roughly simulate userspace passing around the file.
Adding the dup() test is primarily an intermediate step towards verifying
that userspace can read VM/vCPU stats before _and_ after userspace closes
its copy of the VM fd; the dup() test itself is only mildly interesting.

make it easier to test that KVM correct manages VM refcounts for stats

3bcbc20942 selftests/rseq: Play nice with binaries statically linked against glibc 2.35+
To allow running rseq and KVM's rseq selftests as statically linked
binaries, initialize the various "trampoline" pointers to point directly
at the expect glibc symbols, and skip the dlysm() lookups if the rseq
size is non-zero, i.e. the binary is statically linked *and* the libc
registered its own rseq.

Define weak versions of the symbols so as not to break linking against
libc versions that don't support rseq in any capacity.

The KVM selftests in particular are often statically linked so that they
can be run on targets with very limited runtime environments, i.e. test
machines.

031c99e71f selftests: tc: add ConnTrack procfs kconfig
When looking at the TC selftest reports, I noticed one test was failing
because /proc/net/nf_conntrack was not available.

  not ok 373 3992 - Add ct action triggering DNAT tuple conflict
  	Could not match regex pattern. Verify command output:
  cat: /proc/net/nf_conntrack: No such file or directory

719b4774a8 selftests: tc: add 'ct' action kconfig dep
When looking for something else in LKFT reports [1], I noticed most of
the tests were skipped because the "teardown stage" did not complete
successfully.

Pedro found out this is due to the fact CONFIG_NF_FLOW_TABLE is required
but not listed in the 'config' file. Adding it to the list fixes the
issues on LKFT side. CONFIG_NET_ACT_CT is now set to 'm' in the final
kconfig.

fda05798c2 selftests: tc: set timeout to 15 minutes
When looking for something else in LKFT reports [1], I noticed that the
TC selftest ended with a timeout error:

  not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds

The timeout had been introduced 3 years ago, see the Fixes commit below.

This timeout is only in place when executing the selftests via the
kselftests runner scripts. I guess this is not what most TC devs are
using and nobody noticed the issue before.

The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks
like it is plenty more time than what it takes in "normal" conditions.

569f8b501b selftests/arm64: fix build failure during the "emit_tests" step
The build failure reported in [1] occurred because commit <9fc96c7c19df>
("selftests: error out if kernel header files are not yet built") added
a new "kernel_header_files" dependency to "all", and that triggered
another, pre-existing problem. Specifically, the arm64 selftests
override the emit_tests target, and that override improperly declares
itself to depend upon the "all" target.

This is a problem because the "emit_tests" target in lib.mk was not
intended to be overridden. emit_tests is a very simple, sequential build
target that was originally invoked from the "install" target, which in
turn, depends upon "all".

That approach worked for years. But with 9fc96c7c19 in place,
emit_tests failed, because it does not set up all of the elaborate
things that "install" does. And that caused the new
"kernel_header_files" target (which depends upon $(KBUILD_OUTPUT) being
correct) to fail.

Some detail: The "all" target is .PHONY. Therefore, each target that
depends on "all" will cause it to be invoked again, and because
dependencies are managed quite loosely in the selftests Makefiles, many
things will run, even "all" is invoked several times in immediate
succession. So this is not a "real" failure, as far as build steps go:
everything gets built, but "all" reports a problem when invoked a second
time from a bad environment.

To fix this, simply remove the unnecessary "all" dependency from the
overridden emit_tests target. The dependency is still effectively
honored, because again, invocation is via "install", which also depends
upon "all".

An alternative approach would be to harden the emit_tests target so that
it can depend upon "all", but that's a lot more complicated and hard to
get right, and doesn't seem worth it, especially given that emit_tests
should probably not be overridden at all.

c77896b143 selftests/riscv: fix potential build failure during the "emit_tests" step
The riscv selftests (which were modeled after the arm64 selftests) are
improperly declaring the "emit_tests" target to depend upon the "all"
target. This approach, when combined with commit 9fc96c7c19
("selftests: error out if kernel header files are not yet built"), has
caused build failures [1] on arm64, and is likely to cause similar
failures for riscv.

To fix this, simply remove the unnecessary "all" dependency from the
emit_tests target. The dependency is still effectively honored, because
again, invocation is via "install", which also depends upon "all".

An alternative approach would be to harden the emit_tests target so that

ebc27aacee Tracing fixes and clean ups:
- Fix some missing-prototype warnings
 
 - Fix user events struct args (did not include size of struct)
   When creating a user event, the "struct" keyword is to denote
   that the size of the field will be passed in. But the parsing
   failed to handle this case.
 
 - Add selftest to struct sizes for user events
 
 - Fix sample code for direct trampolines.
   The sample code for direct trampolines attached to handle_mm_fault().
   But the prototype changed and the direct trampoline sample code
   was not updated. Direct trampolines needs to have the arguments correct
   otherwise it can fail or crash the system.
 
 - Remove unused ftrace_regs_caller_ret() prototype.
 
 - Quiet false positive of FORTIFY_SOURCE
   Due to backward compatibility, the structure used to save stack traces
   in the kernel had a fixed size of 8. This structure is exported to
   user space via the tracing format file. A change was made to allow
   more than 8 functions to be recorded, and user space now uses the
   size field to know how many functions are actually in the stack.
   But the structure still has size of 8 (even though it points into
   the ring buffer that has the required amount allocated to hold a
   full stack. This was fine until the fortifier noticed that the
   memcpy(&entry->caller, stack, size) was greater than the 8 functions
   and would complain at runtime about it. Hide this by using a pointer
   to the stack location on the ring buffer instead of using the address
   of the entry structure caller field.
 
 - Fix a deadloop in reading trace_pipe that was caused by a mismatch
   between ring_buffer_empty() returning false which then asked to
   read the data, but the read code uses rb_num_of_entries() that
   returned zero, and causing a infinite "retry".
 
 - Fix a warning caused by not using all pages allocated to store
   ftrace functions, where this can happen if the linker inserts a bunch of
   "NULL" entries, causing the accounting of how many pages needed
   to be off.
 
 - Fix histogram synthetic event crashing when the start event is
   removed and the end event is still using a variable from it.
 
 - Fix memory leak in freeing iter->temp in tracing_release_pipe()

   ring buffer that has the required amount allocated to hold a full
   stack.

   This was fine until the fortifier noticed that the
   memcpy(&entry->caller, stack, size) was greater than the 8 functions
   and would complain at runtime about it.

   Hide this by using a pointer to the stack location on the ring buffer
   instead of using the address of the entry structure caller field.

 - Fix a deadloop in reading trace_pipe that was caused by a mismatch
   between ring_buffer_empty() returning false which then asked to read
   the data, but the read code uses rb_num_of_entries() that returned
   zero, and causing a infinite "retry".

 - Fix a warning caused by not using all pages allocated to store ftrace
   functions, where this can happen if the linker inserts a bunch of
   "NULL" entries, causing the accounting of how many pages needed to be
   off.

 - Fix histogram synthetic event crashing when the start event is
   removed and the end event is still using a variable from it

 - Fix memory leak in freeing iter->temp in tracing_release_pipe()

e8b03aef19 tools: timers: fix freq average calculation
Delete a duplicate assignment from this function implementation.
The note means ppm is average of the two actual freq samples.
But ppm have a duplicate assignment.
