Pull kvm fixes from Paolo Bonzini:
"ARM:
- Correctly handle 'invariant' system registers for protected VMs
- Improved handling of VNCR data aborts, including external aborts
- Fixes for handling of FEAT_RAS for NV guests, providing a sane
fault context during SEA injection and preventing the use of
RASv1p1 fault injection hardware
- Ensure that page table destruction when a VM is destroyed gives an
opportunity to reschedule
- Large fix to KVM's infrastructure for managing guest context loaded
on the CPU, addressing issues where the output of AT emulation
doesn't get reflected to the guest
- Fix AT S12 emulation to actually perform stage-2 translation when
necessary
- Avoid attempting vLPI irqbypass when GICv4 has been explicitly
disabled for a VM
- Minor KVM + selftest fixes
RISC-V:
- Fix pte settings within kvm_riscv_gstage_ioremap()
- Fix comments in kvm_riscv_check_vcpu_requests()
- Fix stack overrun when setting vlenb via ONE_REG
x86:
- Use array_index_nospec() to sanitize the target vCPU ID when
handling PV IPIs and yields as the ID is guest-controlled.
- Drop a superfluous cpumask_empty() check when reclaiming SEV
memory, as the common case, by far, is that at least one CPU will
have entered the VM, and wbnoinvd_on_cpus_mask() will naturally
handle the rare case where the set of have_run_cpus is empty.
Selftests (not KVM):
- Rename the is_signed_type() macro in kselftest_harness.h to
is_signed_var() to fix a collision with linux/overflow.h. The
collision generates compiler warnings due to the two macros having
different meaning"

blk-zoned: Fix a lockdep complaint about recursive locking
loop: fix zero sized loop for block special file
|
|
Add a new command line option --no_ublk_fixed_fd that excludes the ublk
control device (/dev/ublkcN) from io_uring's registered files array.
When this option is used, only backing files are registered starting
from index 1, while the ublk control device is accessed using its raw
file descriptor.
Add ublk_get_registered_fd() helper function that returns the appropriate
file descriptor for use with io_uring operations.
Key optimizations implemented:
- Cache UBLKS_Q_NO_UBLK_FIXED_FD flag in ublk_queue.flags to avoid
reading dev->no_ublk_fixed_fd in fast path
- Cache ublk char device fd in ublk_queue.ublk_fd for fast access
- Update ublk_get_registered_fd() to use ublk_queue * parameter
- Update io_uring_prep_buf_register/unregister() to use ublk_queue *
- Replace ublk_device * access with ublk_queue * access in fast paths
Also pass --no_ublk_fixed_fd to test_stress_04.sh for covering
plain ublk char device mode.

FORCE_READ() converts input value x to its pointer type then reads from
address x. This is wrong. If x is a non-pointer, it would be caught it
easily. But all FORCE_READ() callers are trying to read from a pointer
and FORCE_READ() basically reads a pointer to a pointer instead of the
original typed pointer. Almost no access violation was found, except the
one from split_huge_page_test.
Fix it by implementing a simplified READ_ONCE() instead.

When synthesizing build-ids, for build ID mmap2 events, they will be
added for data mmaps if -d/--data is specified. The files opened for
their build IDs may block on the open causing perf to hang during
synthesis. There is some robustness in existing calls to
filename__read_build_id by checking the file path is to a regular
file, which unfortunately fails for symlinks. Rather than adding more
is_regular_file calls, switch filename__read_build_id to take a
"block" argument and specify O_NONBLOCK when this is false. The
existing is_regular_file checking callers and the event synthesis
callers are made to pass false and thereby avoiding the hang.

The e_ident is part of the ehdr and so reading it a second time would
mean the read ehdr was displaced by 16-bytes. Switch from stdio to
open/read/lseek syscalls for similarity with the symbol-elf version of

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Fix rtla and latency tooling pkg-config errors
If libtraceevent and libtracefs is installed, but their corresponding
'.pc' files are not installed, it reports that the libraries are
missing and confuses the developer. Instead, report that the
pkg-config files are missing and should be installed.
- Fix overflow bug of the parser in trace_get_user()
trace_get_user() uses the parsing functions to parse the user space
strings. If the parser fails due to incorrect processing, it doesn't
terminate the buffer with a nul byte. Add a "failed" flag to the
parser that gets set when parsing fails and is used to know if the
buffer is fine to use or not.
- Remove a semicolon that was at an end of a comment line
- Fix register_ftrace_graph() to unregister the pm notifier on error
The register_ftrace_graph() registers a pm notifier but there's an
error path that can exit the function without unregistering it. Since
the function returns an error, it will never be unregistered.
- Allocate and copy ftrace hash for reader of ftrace filter files
When the set_ftrace_filter or set_ftrace_notrace files are open for
read, an iterator is created and sets its hash pointer to the
associated hash that represents filtering or notrace filtering to it.
The issue is that the hash it points to can change while the
iteration is happening. All the locking used to access the tracer's
hashes are released which means those hashes can change or even be
freed. Using the hash pointed to by the iterator can cause UAF bugs
or similar.
Have the read of these files allocate and copy the corresponding
hashes and use that as that will keep them the same while the
iterator is open. This also simplifies the code as opening it for
write already does an allocate and copy, and now that the read is
doing the same, there's no need to check which way it was opened on
the release of the file, and the iterator hash can always be freed.
- Fix function graph to copy args into temp storage
The output of the function graph tracer shows both the entry and the
exit of a function. When the exit is right after the entry, it
combines the two events into one with the output of "function();",
instead of showing:
function() {
}
In order to do this, the iterator descriptor that reads the events
includes storage that saves the entry event while it peaks at the
next event in the ring buffer. The peek can free the entry event so
the iterator must store the information to use it after the peek.
With the addition of function graph tracer recording the args, where
the args are a dynamic array in the entry event, the temp storage
does not save them. This causes the args to be corrupted or even
cause a read of unsafe memory.
Add space to save the args in the temp storage of the iterator.
- Fix race between ftrace_dump and reading trace_pipe
ftrace_dump() is used when a crash occurs where the ftrace buffer
will be printed to the console. But it can also be triggered by
sysrq-z. If a sysrq-z is triggered while a task is reading trace_pipe
it can cause a race in the ftrace_dump() where it checks if the
buffer has content, then it checks if the next event is available,
and then prints the output (regardless if the next event was
available or not). Reading trace_pipe at the same time can cause it
to not be available, and this triggers a WARN_ON in the print. Move
the printing into the check if the next event exists or not

regression. New user tools releases will not use such a mode,
the old release with a new kernel now will have warning about
deprecated behavior, and we prepare to remove this legacy mode
after about a year later
- The rename in kernel causing user tools build failure, revert
the rename in mdp_superblock_s
- Fix a regression that interrupted resync can be shown as
recover from mdstat or sysfs
- Improve file size detection for loop, particularly for networked
file systems, by using getattr to get the size rather than the
cached inode size.

Add a selftest to verify bonding behavior when `lacp_active` is set to `off`.
The test checks the following:
- The passive LACP bond should not send LACPDUs before receiving a partner's
LACPDU.
- The transmitted LACPDUs must not include the active flag.
- After transitioning to EXPIRED and DEFAULTED states, the passive side should
still not initiate LACPDUs.

Commit 26dda5769509 "tools/bootconfig: Cleanup bootconfig footer size

BOOTCONFIG_FOOTER_SIZE macro, which expands to an expression of type
size_t, which is unsigned.
On 32-bit architectures with LFS enabled (i.e. off_t is 64-bit), the
seek offset of -BOOTCONFIG_FOOTER_SIZE now turns into a positive
value.
Fix this by casting the size to off_t before negating it.
Just in case someone changes BOOTCONFIG_MAGIC_LEN to have type size_t
later, do the same thing to the seek offset of -BOOTCONFIG_MAGIC_LEN.

Rename is_signed_type() to is_signed_var() to avoid colliding with a macro
of the same name defined by tools' linux/overflow.h. This fixes warnings
(and presumably potential test failures) in tests that utilize the
selftests harness and happen to (indirectly) include overflow.h.

When compiling with LLVM and CONFIG_LTO_CLANG is set, there exist many
objtool warnings "sibling call from callable instruction with modified
stack frame".
For this special case, the related object file shows that there is no
generated relocation section '.rela.discard.tablejump_annotate' for the
table jump instruction jirl, thus objtool can not know that what is the
actual destination address.
It needs to do something on the LLVM side to make sure that there is the
relocation section '.rela.discard.tablejump_annotate' if LTO is enabled,
but in order to maintain compatibility for the current LLVM compiler,
this can be done in the kernel Makefile for now. Ensure it is aware of
linker with LTO, '--loongarch-annotate-tablejump' needs to be passed via
'-mllvm' to ld.lld.
Before doing the above changes, it should handle the special case of the
relocation section '.rela.discard.tablejump_annotate' to get the correct
table size first, otherwise there are many objtool warnings and errors
if LTO is enabled.
There are many different rodata for each function if LTO is enabled, it
is necessary to enhance get_rodata_table_size_by_table_annotate().

We can use UFFD to easily assert invalid multi VMA moves, so do so,
asserting expected behaviour when VMAs invalid for a multi VMA operation
are encountered.
We assert both that such operations are not permitted, and that we do not
even attempt to move the first VMA under these circumstances.
We also assert that we can still move a single VMA regardless.
We then assert that a partial failure can occur if the invalid VMA appears
later in the range of multiple VMAs, both at the very next VMA, and also at
the end of the range.
As part of this change, we are using the is_range_valid() helper more
aggressively. Therefore, fix a bug where stale buffered data would hang
around on success, causing subsequent calls to is_range_valid() to
potentially give invalid results.
We simply have to fflush() the stream on success to resolve this issue.

Commit 857d18f23ab1 ("cleanup: Introduce ACQUIRE() and ACQUIRE_ERR() for
conditional locks") accidentally broke the radix tree, VMA userland tests
by including linux/args.h which is not present in the tools/include
directory.
This patch copies this over and adds an #ifdef block to avoid duplicate
__CONCAT declaration in conflict with system headers when we ultimately
include this.

This modification is linked to the parent commit where the received
ADD_ADDR limit was accidentally reset when the endpoints were flushed.
To validate that, the test is now flushing endpoints after having set
new limits, and before checking them.
The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.

The CI has hit a couple of cases of:
RUN global.data_steal ...
tls.c:2762:data_steal:Expected recv(cfd, buf2, sizeof(buf2), MSG_DONTWAIT) (20000) == -1 (-1)
data_steal: Test terminated by timeout
FAIL global.data_steal
Looks like the 2msec sleep is not long enough. Make the sleep longer,
and then instead of second sleep wait for the thieving process to exit.
That way we can be sure it called recv() before us.
While at it also avoid trying to steal more than a record, this seems
