tracing fixes for v6.13:
- Replace trace_check_vprintf() with test_event_printk() and ignore_event() The function test_event_printk() checks on boot up if the trace event printf() formats dereference any pointers, and if they do, it then looks at the arguments to make sure that the pointers they dereference will exist in the event on the ring buffer. If they do not, it issues a WARN_ON() as it is a likely bug. But this isn't the case for the strings that can be dereferenced with "%s", as some trace events (notably RCU and some IPI events) save a pointer to a static string in the ring buffer. As the string it points to lives as long as the kernel is running, it is not a bug to reference it, as it is guaranteed to be there when the event is read. But it is also possible (and a common bug) to point to some allocated string that could be freed before the trace event is read and the dereference is to bad memory. This case requires a run time check. The previous way to handle this was with trace_check_vprintf() that would process the printf format piece by piece and send what it didn't care about to vsnprintf() to handle arguments that were not strings. This kept it from having to reimplement vsnprintf(). But it relied on va_list implementation and for architectures that copied the va_list and did not pass it by reference, it wasn't even possible to do this check and it would be skipped. As 64bit x86 passed va_list by reference, most events were tested and this kept out bugs where strings would have been dereferenced after being freed. Instead of relying on the implementation of va_list, extend the boot up test_event_printk() function to validate all the "%s" strings that can be validated at boot, and for the few events that point to strings outside the ring buffer, flag both the event and the field that is dereferenced as "needs_test". Then before the event is printed, a call to ignore_event() is made, and if the event has the flag set, it iterates all its fields and for every field that is to be tested, it will read the pointer directly from the event in the ring buffer and make sure that it is valid. If the pointer is not valid, it will print a WARN_ON(), print out to the trace that the event has unsafe memory and ignore the print format. With this new update, the trace_check_vprintf() can be safely removed and now all events can be verified regardless of architecture. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZ2IqiRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qlfgAP9hJFl6zhA5GGRo905G9JWFHkbNNjgp WfQ0oMU2Eo1q+AEAmb5d3wWfWJAa+AxiiDNeZ28En/+ZbmjhSe6fPpR4egU= =LRKi -----END PGP SIGNATURE----- Merge tag 'trace-v6.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: "Replace trace_check_vprintf() with test_event_printk() and ignore_event() The function test_event_printk() checks on boot up if the trace event printf() formats dereference any pointers, and if they do, it then looks at the arguments to make sure that the pointers they dereference will exist in the event on the ring buffer.

btrfs: tree-checker: reject inline extent items with 0 ref count
[BUG]
There is a bug report in the mailing list where btrfs_run_delayed_refs()
failed to drop the ref count for logical 25870311358464 num_bytes
2113536.
The involved leaf dump looks like this:
item 166 key (25870311358464 168 2113536) itemoff 10091 itemsize 50
extent refs 1 gen 84178 flags 1
ref#0: shared data backref parent 32399126528000 count 0 <<<
ref#1: shared data backref parent 31808973717504 count 1
Notice the count number is 0.
[CAUSE]
There is no concrete evidence yet, but considering 0 -> 1 is also a
single bit flipped, it's possible that hardware memory bitflip is
involved, causing the on-disk extent tree to be corrupted.
[FIX]
To prevent us reading such corrupted extent item, or writing such
damaged extent item back to disk, enhance the handling of
BTRFS_EXTENT_DATA_REF_KEY and BTRFS_SHARED_DATA_REF_KEY keys for both
inlined and key items, to detect such 0 ref count and reject them.

btrfs: split bios to the fs sector size boundary
Btrfs like other file systems can't really deal with I/O not aligned to
it's internal block size (which strangely is called sector size in
btrfs, for historical reasons), but the block layer split helper doesn't
even know about that.
Round down the split boundary so that all I/Os are aligned.

btrfs: fix improper generation check in snapshot delete
We have been using the following check if (generation <= root->root_key.offset) to make decisions about whether or not to visit a node during snapshot delete. This is because for normal subvolumes this is set to 0, and for snapshots it's set to the creation generation. The idea being that if the generation of the node is less than or equal to our creation generation then we don't need to visit that node, because it doesn't belong to us, we can simply drop our reference and move on. However reloc roots don't have their generation stored in root->root_key.offset, instead that is the objectid of their corresponding fs root. This means we can incorrectly not walk into nodes that need to be dropped when deleting a reloc root. There are a variety of consequences to making the wrong choice in two distinct areas. visit_node_for_delete() 1. False positive. We think we are newer than the block when we really aren't. We don't visit the node and drop our reference to the node and carry on. This would result in leaked space. 2. False negative. We do decide to walk down into a block that we should have just dropped our reference to. However this means that the child node will have refs > 1, so we will switch to UPDATE_BACKREF, and then the subsequent walk_down_proc() will notice that btrfs_header_owner(node) != root->root_key.objectid and it'll break out of the loop, and then walk_up_proc() will drop our reference, so this appears to be ok. do_walk_down() 1. False positive. We are in UPDATE_BACKREF and incorrectly decide that we are done and don't need to update the backref for our lower nodes. This is another case that simply won't happen with relocation, as we only have to do UPDATE_BACKREF if the node below us was shared and didn't have FULL_BACKREF set, and since we don't own that node because we're a reloc root we actually won't end up in this case. 2. False negative. Again this is tricky because as described above, we simply wouldn't be here from relocation, because we don't own any of the nodes because we never set btrfs_header_owner() to the reloc root objectid, and we always use FULL_BACKREF, we never actually need to set FULL_BACKREF on any children. Having spent a lot of time stressing relocation/snapshot delete recently I've not seen this pop in practice. But this is objectively incorrect, so fix this to get the correct starting generation based on the root we're dropping to keep me from thinking there's a problem here.

Ftrace fixes for 6.13:
- Always try to initialize the idle functions when graph tracer starts A bug was found that when a CPU is offline when graph tracing starts and then comes online, that CPU is not traced. The fix to that was to move the initialization of the idle shadow stack over to the hot plug online logic, which also handle onlined CPUs. The issue was that it removed the initialization of the shadow stack when graph tracing starts, but the callbacks to the hot plug logic do nothing if graph tracing isn't currently running. Although that fix fixed the onlining of a CPU during tracing, it broke the CPUs that were already online. - Have microblaze not try to get the "true parent" in function tracing If function tracing and graph tracing are both enabled at the same time the parent of the functions traced by the function tracer may sometimes be the graph tracing trampoline. The graph tracing hijacks the return pointer of the function to trace it, but that can interfere with the function tracing parent output. This was fixed by using the ftrace_graph_ret_addr() function passing in the kernel stack pointer using the ftrace_regs_get_stack_pointer() function. But Al Viro reported that Microblaze does not implement the kernel_stack_pointer(regs) helper function that ftrace_regs_get_stack_pointer() uses and fails to compile when function graph tracing is enabled. It was first thought that this was a microblaze issue, but the real cause is that this only works when an architecture implements HAVE_DYNAMIC_FTRACE_WITH_ARGS, as a requirement for that config is to have ftrace always pass a valid ftrace_regs to the callbacks. That also means that the architecture supports ftrace_regs_get_stack_pointer() Microblaze does not set HAVE_DYNAMIC_FTRACE_WITH_ARGS nor does it implement ftrace_regs_get_stack_pointer() which caused it to fail to build.

tracing: Check "%s" dereference via the field and not the TP_printk format
The TP_printk() portion of a trace event is executed at the time a event
is read from the trace. This can happen seconds, minutes, hours, days,
months, years possibly later since the event was recorded. If the print
format contains a dereference to a string via "%s", and that string was
allocated, there's a chance that string could be freed before it is read
by the trace file.
To protect against such bugs, there are two functions that verify the
event. The first one is test_event_printk(), which is called when the
event is created. It reads the TP_printk() format as well as its arguments
to make sure nothing may be dereferencing a pointer that was not copied
into the ring buffer along with the event. If it is, it will trigger a
WARN_ON().
For strings that use "%s", it is not so easy. The string may not reside in
the ring buffer but may still be valid. Strings that are static and part
of the kernel proper which will not be freed for the life of the running
system, are safe to dereference. But to know if it is a pointer to a
static string or to something on the heap can not be determined until the
event is triggered.
This brings us to the second function that tests for the bad dereferencing
of strings, trace_check_vprintf(). It would walk through the printf format
looking for "%s", and when it finds it, it would validate that the pointer
is safe to read. If not, it would produces a WARN_ON() as well and write
into the ring buffer "[UNSAFE-MEMORY]".
The problem with this is how it used va_list to have vsnprintf() handle
all the cases that it didn't need to check. Instead of re-implementing
vsnprintf(), it would make a copy of the format up to the %s part, and
call vsnprintf() with the current va_list ap variable, where the ap would
then be ready to point at the string in question.
For architectures that passed va_list by reference this was possible. For
architectures that passed it by copy it was not. A test_can_verify()
function was used to differentiate between the two, and if it wasn't
possible, it would disable it.
Even for architectures where this was feasible, it was a stretch to rely
on such a method that is undocumented, and could cause issues later on
with new optimizations of the compiler.
Instead, the first function test_event_printk() was updated to look at
"%s" as well. If the "%s" argument is a pointer outside the event in the
ring buffer, it would find the field type of the event that is the problem
and mark the structure with a new flag called "needs_test". The event
itself will be marked by TRACE_EVENT_FL_TEST_STR to let it be known that
this event has a field that needs to be verified before the event can be
printed using the printf format.
When the event fields are created from the field type structure, the
fields would copy the field type's "needs_test" value.
Finally, before being printed, a new function ignore_event() is called
which will check if the event has the TEST_STR flag set (if not, it
returns false). If the flag is set, it then iterates through the events
fields looking for the ones that have the "needs_test" flag set.
Then it uses the offset field from the field structure to find the pointer
in the ring buffer event. It runs the tests to make sure that pointer is
safe to print and if not, it triggers the WARN_ON() and also adds to the
trace output that the event in question has an unsafe memory access.
The ignore_event() makes the trace_check_vprintf() obsolete so it is
removed.

tracing: Add "%s" check in test_event_printk()
The test_event_printk() code makes sure that when a trace event is
registered, any dereferenced pointers in from the event's TP_printk() are
pointing to content in the ring buffer. But currently it does not handle
"%s", as there's cases where the string pointer saved in the ring buffer
points to a static string in the kernel that will never be freed. As that
is a valid case, the pointer needs to be checked at runtime.
Currently the runtime check is done via trace_check_vprintf(), but to not
have to replicate everything in vsnprintf() it does some logic with the
va_list that may not be reliable across architectures. In order to get rid
of that logic, more work in the test_event_printk() needs to be done. Some
of the strings can be validated at this time when it is obvious the string
is valid because the string will be saved in the ring buffer content.
Do all the validation of strings in the ring buffer at boot in
test_event_printk(), and make sure that the field of the strings that
point into the kernel are accessible. This will allow adding checks at
runtime that will validate the fields themselves and not rely on paring
the TP_printk() format at runtime.

tracing: Add missing helper functions in event pointer dereference check
The process_pointer() helper function looks to see if various trace event
macros are used. These macros are for storing data in the event. This
makes it safe to dereference as the dereference will then point into the
event on the ring buffer where the content of the data stays with the
event itself.
A few helper functions were missing. Those were:
__get_rel_dynamic_array()
__get_dynamic_array_len()
__get_rel_dynamic_array_len()
__get_rel_sockaddr()
Also add a helper function find_print_string() to not need to use a middle
man variable to test if the string exists.

tracing: Fix test_event_printk() to process entire print argument
The test_event_printk() analyzes print formats of trace events looking for
cases where it may dereference a pointer that is not in the ring buffer
which can possibly be a bug when the trace event is read from the ring
buffer and the content of that pointer no longer exists.
The function needs to accurately go from one print format argument to the
next. It handles quotes and parenthesis that may be included in an
argument. When it finds the start of the next argument, it uses a simple
"c = strstr(fmt + i, ',')" to find the end of that argument!
In order to include "%s" dereferencing, it needs to process the entire
content of the print format argument and not just the content of the first
',' it finds. As there may be content like:
({ const char *saved_ptr = trace_seq_buffer_ptr(p); static const char
*access_str[] = { "---", "--x", "w--", "w-x", "-u-", "-ux", "wu-", "wux"
}; union kvm_mmu_page_role role; role.word = REC->role;
trace_seq_printf(p, "sp gen %u gfn %llx l%u %u-byte q%u%s %s%s" " %snxe
%sad root %u %s%c", REC->mmu_valid_gen, REC->gfn, role.level,
role.has_4_byte_gpte ? 4 : 8, role.quadrant, role.direct ? " direct" : "",
access_str[role.access], role.invalid ? " invalid" : "", role.efer_nx ? ""
: "!", role.ad_disabled ? "!" : "", REC->root_count, REC->unsync ?
"unsync" : "sync", 0); saved_ptr; })
Which is an example of a full argument of an existing event. As the code
already handles finding the next print format argument, process the
argument at the end of it and not the start of it. This way it has both
the start of the argument as well as the end of it.
Add a helper function "process_pointer()" that will do the processing during
the loop as well as at the end. It also makes the code cleaner and easier
to read.

fortify: Hide run-time copy size from value range tracking
GCC performs value range tracking for variables as a way to provide better
diagnostics. One place this is regularly seen is with warnings associated
with bounds-checking, e.g. -Wstringop-overflow, -Wstringop-overread,
-Warray-bounds, etc. In order to keep the signal-to-noise ratio high,
warnings aren't emitted when a value range spans the entire value range
representable by a given variable. For example:
unsigned int len;
char dst[8];
...
memcpy(dst, src, len);
If len's value is unknown, it has the full "unsigned int" range of [0,
UINT_MAX], and GCC's compile-time bounds checks against memcpy() will
be ignored. However, when a code path has been able to narrow the range:
if (len > 16)
return;
memcpy(dst, src, len);
Then the range will be updated for the execution path. Above, len is
now [0, 16] when reading memcpy(), so depending on other optimizations,
we might see a -Wstringop-overflow warning like:
error: '__builtin_memcpy' writing between 9 and 16 bytes into region of size 8 [-Werror=stringop-overflow]
When building with CONFIG_FORTIFY_SOURCE, the fortified run-time bounds
checking can appear to narrow value ranges of lengths for memcpy(),
depending on how the compiler constructs the execution paths during
optimization passes, due to the checks against the field sizes. For
example:
if (p_size_field != SIZE_MAX &&
p_size != p_size_field && p_size_field < size)
As intentionally designed, these checks only affect the kernel warnings
emitted at run-time and do not block the potentially overflowing memcpy(),
so GCC thinks it needs to produce a warning about the resulting value
range that might be reaching the memcpy().
We have seen this manifest a few times now, with the most recent being
with cpumasks:
In function ‘bitmap_copy’,

ftrace: Do not find "true_parent" if HAVE_DYNAMIC_FTRACE_WITH_ARGS is not set
When function tracing and function graph tracing are both enabled (in
different instances) the "parent" of some of the function tracing events
is "return_to_handler" which is the trampoline used by function graph
tracing. To fix this, ftrace_get_true_parent_ip() was introduced that
returns the "true" parent ip instead of the trampoline.
To do this, the ftrace_regs_get_stack_pointer() is used, which uses
kernel_stack_pointer(). The problem is that microblaze does not implement
kerenl_stack_pointer() so when function graph tracing is enabled, the
build fails. But microblaze also does not enabled HAVE_DYNAMIC_FTRACE_WITH_ARGS.
That option has to be enabled by the architecture to reliably get the
values from the fregs parameter passed in. When that config is not set,
the architecture can also pass in NULL, which is not tested for in that
function and could cause the kernel to crash.

fgraph: Still initialize idle shadow stacks when starting
A bug was discovered where the idle shadow stacks were not initialized
for offline CPUs when starting function graph tracer, and when they came
online they were not traced due to the missing shadow stack. To fix
this, the idle task shadow stack initialization was moved to using the
CPU hotplug callbacks. But it removed the initialization when the
function graph was enabled. The problem here is that the hotplug
callbacks are called when the CPUs come online, but the idle shadow
stack initialization only happens if function graph is currently
active. This caused the online CPUs to not get their shadow stack
initialized.
The idle shadow stack initialization still needs to be done when the
function graph is registered, as they will not be allocated if function
graph is not registered.

erofs: use buffered I/O for file-backed mounts by default
For many use cases (e.g. container images are just fetched from remote),
performance will be impacted if underlay page cache is up-to-date but
direct i/o flushes dirty pages first.
Instead, let's use buffered I/O by default to keep in sync with loop
devices and add a (re)mount option to explicitly give a try to use
direct I/O if supported by the underlying files.
The container startup time is improved as below:
[workload] docker.io/library/workpress:latest
unpack 1st run non-1st runs
EROFS snapshotter buffered I/O file 4.586404265s 0.308s 0.198s
EROFS snapshotter direct I/O file 4.581742849s 2.238s 0.222s
EROFS snapshotter loop 4.596023152s 0.346s 0.201s
Overlayfs snapshotter 5.382851037s 0.206s 0.214s

Record `m_sb` and `m_dif` to replace `m_fscache`, `m_daxdev`, `m_fp` and `m_dax_part_off` in order to simplify the codebase.

bpf: Avoid deadlock caused by nested kprobe and fentry bpf programs
BPF program types like kprobe and fentry can cause deadlocks in certain situations. If a function takes a lock and one of these bpf programs is hooked to some point in the function's critical section, and if the bpf program tries to call the same function and take the same lock it will lead to deadlock. These situations have been reported in the following bug reports. In percpu_freelist - Link: https://lore.kernel.org/bpf/CAADnVQLAHwsa+2C6j9+UC6ScrDaN9Fjqv1WjB1pP9AzJLhKuLQ@mail.gmail.com/T/ Link: https://lore.kernel.org/bpf/CAPPBnEYm+9zduStsZaDnq93q1jPLqO-PiKX9jy0MuL8LCXmCrQ@mail.gmail.com/T/ In bpf_lru_list - Link: https://lore.kernel.org/bpf/CAPPBnEajj+DMfiR_WRWU5=6A7KKULdB5Rob_NJopFLWF+i9gCA@mail.gmail.com/T/ Link: https://lore.kernel.org/bpf/CAPPBnEZQDVN6VqnQXvVqGoB+ukOtHGZ9b9U0OLJJYvRoSsMY_g@mail.gmail.com/T/ Link: https://lore.kernel.org/bpf/CAPPBnEaCB1rFAYU7Wf8UxqcqOWKmRPU1Nuzk3_oLk6qXR7LBOA@mail.gmail.com/T/ Similar bugs have been reported by syzbot. In queue_stack_maps - Link: https://lore.kernel.org/lkml/0000000000004c3fc90615f37756@google.com/ Link: https://lore.kernel.org/all/20240418230932.2689-1-hdanton@sina.com/T/ In lpm_trie - Link: https://lore.kernel.org/linux-kernel/00000000000035168a061a47fa38@google.com/T/ In ringbuf - Link: https://lore.kernel.org/bpf/20240313121345.2292-1-hdanton@sina.com/T/ Prevent kprobe and fentry bpf programs from attaching to these critical sections by removing CC_FLAGS_FTRACE for percpu_freelist.o, bpf_lru_list.o, queue_stack_maps.o, lpm_trie.o, ringbuf.o files. The bugs reported by syzbot are due to tracepoint bpf programs being called in the critical sections. This patch does not aim to fix deadlocks caused by tracepoint programs. However, it does prevent deadlocks from occurring in similar situations due to kprobe and fentry programs.
