Recently, I noticed a selftest failure in my local environment. The test_parse_test_list_file writes some data to /tmp/bpf_arg_parsing_test.XXXXXX and parse_test_list_file() will read the data back. However, after writing data to that file, we forget to call fsync() and it's causing testing failure in my laptop. This patch helps fix it by adding the missing fsync() call.

could we just close the fp stream instead flushing it twice?
maybe something like below, but not sure ferror will work after the fclose call

we should probably fclose() after ferror().
but the original fix works, though I think we should do fsync(fp) instead to say within FILE-based APIs.

I accidentally applied it to bpf-next tree and had to drop it from there.
It actually doesn't apply to bpf tree cleanly, so please rebase and resend.
But first, did you validate that fclose() actually fixes the issue for you? Because I don't think fclose() will call fsync(), will it? fclose() will basically do the same thing as should be done with fflush() anyways, so I have my doubts.
Furthermore, your commit message doesn't correspond to your patch. There is no fsync() call here, please fix that as well.

Thanks for pointing this out. Adding fclose() resolves the issue on my laptop too. I prefer switching back to using fsync() according to your comment.
Best Regards, Xing.

applied to bpf, thanks!
Given you can reproduce this issue locally, do you mind capturing strace log before the fix, with fsync fix, and also with fclose, which you say also fixes the issue. But that makes little sense to me, so I'd like to compare what's going on at syscall level to try to get some idea. Thanks!

I doubt people will be reading this giant log. Please bisect it instead. Since it's not reproducible when /tmp is backed by tmpfs it's probably some change in vfs or in the file system that your laptop is using for /tmp. It changes a user visible behavior of the file system and needs to be investigated, since it may affect more code than just this selftest.

Since it's not reproducible when /tmp is backed by tmpfs it's probably some change in vfs or in the file system that your laptop is using for /tmp. It changes a user visible behavior of the file system and needs to be investigated, since it may affect more code than just this selftest.
dmesg output was certainly too much, but I filtered all that out. Here are relevant pieces of strace log.

So as can be seen above, kernel does see the write(4, <175 bytes of content>) in all cases (so libc's fflush(fp) works as expected), but without either fsync(4) or close(4), kernel won't return those 175 bytes if we open() same file (returning FD 5 this time).
Is that a reasonable behavior of the kernel? I don't know, it would be good for FS folks to double check/confirm. The complication here is that we have two FDs open against the same underlying file (so my assumption is that kernel should share underlying page cache data), and documentation I've found isn't particularly clear on guarantees in that case.
write()'s man page states:
POSIX requires that a read(2) which can be proved to occur after a
write() has returned returns the new data. Note that not all file systems are POSIX conforming.
(but this doesn't clarify if all this is applied only within the same *FD*)
POSIX itself says:
Writes can be serialized with respect to other reads and writes.
If a read() of file data can be proven (by any means) to occur after a write() of the data, it must reflect that write(), even if the calls are made by different processes. A similar requirement applies to multiple write operations to the same file position. This is needed to guarantee the propagation of data from write() calls to subsequent read() calls. This requirement is particularly significant for networked file systems, where some caching schemes violate these semantics.
But again, no mention of multiple FDs opened against the same underlying file.
So unclear, which is why it would be nice for FS folks to double check. It's certainly a change in behavior, it used to work reliably before. [0] is the source code of the test (and note that we now added fsync(), without it the test is now broken).

It's a 9p bug, sorry. tentative fix: https://lkml.kernel.org/r/20251022-mmap-regression-v1-1-980365ee524e@codewre...

I'll send the fix to Linus once someone can confirm this works for this usecase as well (and try to improve our testing a bit... maybe just run the bpf test suite for starters)
Hello:
This patch was applied to bpf/bpf.git (master) by Andrii Nakryiko andrii@kernel.org:
On Thu, 16 Oct 2025 11:53:30 +0800 you wrote:
test_parse_test_list_file writes some data to /tmp/bpf_arg_parsing_test.XXXXXX and parse_test_list_file() will read the data back. However, after writing data to that file, we forget to call fsync() and it's causing testing failure in my laptop. This patch helps fix it by adding the missing fsync() call.
