Background of this patch set can be found in v1:
https://lore.kernel.org/all/20240613133711.2867745-1-zhengyejian1@huawei.com/
Here add a reproduction to show the impact to livepatch:
1. Add following hack to make livepatch-sample.ko do patch on do_one_initcall()
which has an overriden weak function behind in vmlinux, then print the
actually used __fentry__ location:

.new_func = livepatch_cmdline_proc_show,

};
2. We can see the size of do_one_initcall() is 0x27e:
$ nm -nS vmlinux | grep do_one_initcall
ffffffff810021e0 000000000000027e T do_one_initcall
3. Insert the livepatch ko, the expected ftrace_loc is do_one_initcall+0x4/0x27e but
actually do_one_initcall+0x294/0x2c0 which is invalid, also its size is inaccurate.
Then this livepatch can not properly work!!!

Changes:
v1->v2:
- Drop patch which titled "kallsyms: Optimize multiple times of realloc() to one time of malloc()"
as suggested by Masahiro;
Link: https://lore.kernel.org/all/CAK7LNAQkSnZ1nVXiZH9kg52H-A_=urcsv-W7wGXvunMGhGX8Vw@mail.gmail.com/
- Changes in PATCH 1/5:
- Change may_exist_hole_after_symbol() to has_hole() and return bool type;
- User realloc instead of malloc another table in emit_hole_symbols();
Link: https://lore.kernel.org/all/CAK7LNAQaLc6aDK85qQtPHoCkQSGyL-TxXjpgJTfehe2Q1=jMSA@mail.gmail.com/
- Use empty symbol type/name as a special case to represent the hole instead of
using symbol "t__hole_symbol_XXXXX";
Link: https://lore.kernel.org/all/CAK7LNARiR5z9hPRG932T7YjRWqkX_qZ7WKmbxx7iTo2w5YJojQ@mail.gmail.com/
- Changes in PATCH 3/5:
- Now name of hole symbol is NULL, so if __fentry__ is located in a hole,
kallsyms_lookup() find an NULL name then will return 0, so drop the
needless kallsyms_is_hole_symbol().

When a weak type function is overridden, its symbol will be removed
from the symbol table, but its code will not be removed. Besides,
due to lacking of size for kallsyms, kernel compute function size by
substracting its symbol address from its next symbol address (see
kallsyms_lookup_size_offset()). These will cause that size of some
function is computed to be larger than it actually is, just because
symbol of its following weak function is removed.
This issue also causes multiple __fentry__ locations to be counted in
the same function scope, and eventually causes ftrace_location() to find
wrong __fentry__ location. It was reported in
Link: https://lore.kernel.org/all/20240607115211.734845-1-zhengyejian1@huawei.com/
Peter suggested to change scipts/kallsyms.c to emit readily
identifiable symbol names for all the weak junk.
So in this patch:
1. Pass size info to scripts/kallsyms (see mksysmap());
2. Traverse sorted function symbols, if one function address plus its
size less than next function address, it means there's a hole, with
Masahiro's suggestion, then emit a symbol there of which type and
name are both empty to represent the hole.

When a weak type function is overridden, its symbol will be removed
from the symbol table, but its code will not been removed. It will
cause find_kallsyms_symbol() to compute a larger function size than
it actually is, just because symbol of its following weak function is
removed.
To fix this issue, check that given address is within the size of
the function found.

ftrace_location() was changed to not only return the __fentry__ location
when called for the __fentry__ location, but also when called for the
sym+0 location after commit aebfd12521d9 ("x86/ibt,ftrace: Search for
__fentry__ location"). That is, if sym+0 location is not __fentry__,
ftrace_location() would find one over the entire size of the sym.
However, there is case that more than one __fentry__ exist in the sym
range (described below) and ftrace_location() would find wrong __fentry__
location by binary searching, which would cause its users like livepatch/
kprobe/bpf to not work properly on this sym!
The case is that, based on current compiler behavior, suppose:
- function A is followed by weak function B1 in same binary file;
- weak function B1 is overridden by function B2;
Then in the final binary file:
- symbol B1 will be removed from symbol table while its instructions are
not removed;
- __fentry__ of B1 will be still in __mcount_loc table;
- function size of A is computed by substracting the symbol address of
A from its next symbol address (see kallsyms_lookup_size_offset()),
but because symbol info of B1 is removed, the next symbol of A is
originally the next symbol of B1. See following example, function
sizeof A will be (symbol_address_C - symbol_address_A):
symbol_address_A
symbol_address_B1 (Not in symbol table)
symbol_address_C
The weak function issue has been discovered in commit b39181f7c690
("ftrace: Add FTRACE_MCOUNT_MAX_OFFSET to avoid adding weak function")
but it didn't resolve the issue in ftrace_location().
To solve the issue, with Peter's suggestions, in previous patches, all
holes in the text have been found and filled with specail symbols, also
the same case with module weak function has been handled. Then check and
skip __fentry__ that locate in the holes.
Also in this patch, introduce module_kallsyms_find_symbol() to check if
a __fentry__ locate in a valid function of the given module. It is needed
because other symbol lookup functions like module_address_lookup() will
find module of the passed address first, but as ftrace_process_locs() is
called, the module has not been fully loaded, so those lookup functions
can not work.
Fixes: aebfd12521d9 ("x86/ibt,ftrace: Search for __fentry__ location")

In ftrace_process_locs(), a series pages are prepared and linked in
start_pg, then fentry records are skipped or added, then unused pages
are freed.
However, assume that all records are skipped, currently the start_pg
will still be in list of ftrace_pages_start but without any record.
Then in ftrace_free_mem() index record by (pg->index - 1) will be out
of bound.
To fix this issue, properly handle with unused start_pg and add
WARN_ON_ONCE() where the records need to be indexed.
Fixes: 26efd79c4624 ("ftrace: Fix possible warning on checking all pages used in ftrace_process_locs()")

After patch titled "ftrace: Skip invalid __fentry__ in
ftrace_process_locs()", __fentry__ locations in overridden weak function
have been checked and skipped, then all records in ftrace_pages are
valid, the FTRACE_MCOUNT_MAX_OFFSET workaround can be reverted, include:
1. commit b39181f7c690 ("ftrace: Add FTRACE_MCOUNT_MAX_OFFSET to avoid
adding weak function")
2. commit 7af82ff90a2b ("powerpc/ftrace: Ignore weak functions")
3. commit f6834c8c59a8 ("powerpc/ftrace: Fix dropping weak symbols with
older toolchains")

Hi all, what is the status of this patch series? I'd really like to see
it or some other fix to this issue merged. The underlying bug is a
significant one that can cause ftrace/livepatch/BPF fentry to fail
silently. I've noticed this bug in another context[1] and realized
they're the same issue.
I'm happy to help with this patch series to address any issues as
needed.

As far as I can see there are problems on build with patch 1, see

Yeah, I see those. Additionally, this patch no longer applies cleanly
to current master, though fixing it up to do so is pretty easy. Having
done that, this series appears to resolve the issues I saw in the other
linked thread.
Zheng, do you plan to send a v3? I'd be happy to help out with this
patch series if you'd like, as I'm hoping to get this issue resolved
(though I am not an ftrace expert).

Sorry to rely so late. Thanks for your feedback!
Steve recently started a discussion of the issue in:
https://lore.kernel.org/all/20241014210841.5a4764de@gandalf.local.home/
but there's no conclusion.
I can rebase this patch series and send a new version first, and
I'm also hoping to get more feedbacks and help to resolve the issue.

Hi Zheng,
I may have misunderstood, but based on the final message from Steven, I
got the sense that the idea listed in that thread didn't work out and
we should proceed with your current approach.
Please consider me an interested party for this patch series, and let
me know if there's anything I can do to help speed it along (co-
develop, test, anything else). And of course, thanks very much for your
work thus far!

This patch set attempts to add length information of symbols to kallsyms,
which can then ensure that there is only one valid fentry within the range
of function length.
However, I think this patch set actually has some performance implications,
including：
1. Adding hole symbols may cause the symbol table to grow significantly;
2. When parsing fentry tables, excluding invalid fentries through kallsyms lookups
may also increase boot or module load times slightly.
The direct cause of this issue is the wrong fentry being founded by ftrace_location(),
following the approach of "FTRACE_MCOUNT_MAX_OFFSET", narrowing down the search range
and re-finding may also solve this problem, demo patch like below (not
fully tested):
diff --git a/kernel/trace/ftrace.c b/kernel/trace/ftrace.c
index 9b17efb1a87d..7d34320ca9d1 100644
--- a/kernel/trace/ftrace.c
+++ b/kernel/trace/ftrace.c
@@ -1678,8 +1678,11 @@ unsigned long ftrace_location(unsigned long ip)
goto out;
/* map sym+0 to __fentry__ */
- if (!offset)
+ if (!offset) {
loc = ftrace_location_range(ip, ip + size - 1);
+ while (loc > ip && loc - ip > FTRACE_MCOUNT_MAX_OFFSET)
+ loc = ftrace_location_range(ip, loc - 1);
+ }
}
Steve, Peter, what do you think?

Sorry for the late reply. Forgot about this as I was focused on other end-of-year issues.

Hmm, removing the weak functions from the __mcount_loc location should also
solve this, as the ftrace_location_range() will not return a weak function
if it's not part of the __mcount_loc table.
That is, would this patchset work?

I only pick patch15 and patch16 into v6.14-rc1, since most of patches in that patches
have already merged, and the issue seems gone, thanks!
