[PATCH 00/21] replace strtok with strtok_r

[PATCH 00/21] replace strtok with strtok_r

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant function.

[PATCH 06/21] app/test-fib: replace strtok with strtok_r

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant function.

[PATCH 13/21] lib/telemetry: replace strtok with strtok_r

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant function.

[PATCH 20/21] examples/l2fwd-crypto: replace strtok with strtok_r

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant function.

You should add a check in checkpatches.sh so we won't add more in future.

Re: [PATCH 00/21] replace strtok with strtok_r

[fengchengwen]

Hi Jie,

Good fix

There are two minor I think need to modify:
1. The [PATCH 13/21] lib/telemetry should be lib/security
2. All commits should add Cc because it's potential bug.

The other LGTM, with above fixed

Lots of churn. And most of these places are never callable from
multiple threads.

It does indicate that some better  arg handling is needed.

could you please use strtok_s instead of strtok_r the former is part of
the C11 standard the latter is not.

For the DPDK examples and apps, I think it's OK if it called in startup then may not need replace.

But as for lib and drivers, I think we shouldn't make such an assumption.

At last I also recommend fix the examples and apps, because people may refer it.

For startup of libs and driver initialization the code is always single threaded.
If not many, many other things would break.

[PATCH v2 00/22] replace strtok with reentrant version

v2:
1. fix commit log.
2. add check in checkpatches.sh.
3. replace strtok_r with strtok_s.
4. add Acked-by.

[PATCH v2 01/22] app/graph: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

[PATCH v2 02/22] app/bbdev: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

[PATCH v2 07/22] app/flow-perf: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

Fixes: 0c8f1f4ab90e ("app/flow-perf: support raw encap/decap actions")
Fixes: 7f37f0936a19 ("app/flow-perf: support meter policy API")
Fixes: 80a323319745 ("app/flow-perf: add destination ports parameter")

[PATCH v2 13/22] security: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

[PATCH v2 21/22] examples/vhost: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial

[PATCH v3 00/22] replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

This patchset replaces strtok with strtok_s in app, example, lib
and drivers. And adds check for use of strtok in checkpatches.sh.

--
v3:
1. fix compile error.
2. use strtok_r instead.
v2:
1. fix commit log.
2. add check in checkpatches.sh.
3. replace strtok_r with strtok_s.
4. add Acked-by.

[PATCH v3 05/22] app/dma-perf: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

[PATCH v3 12/22] eventdev: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

[PATCH v3 17/22] event/cnxk: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

Hi, Tyler Retzlaff

Thanks for your comment.

For the use of strtok_s, I have consulted some documents, see
	https://en.cppreference.com/w/c/string/byte/strtok
It says
"As with all bounds-checked functions, strtok_s only guaranteed to be
available if __STDC_LIB_EXT1__ is defined by the implementation and if
the user defines __STDC_WANT_LIB_EXT1__ to the integer constant 1 before
including <string.h>.
"

I use strtok_s with "#ifdef __STDC_LIB_EXT1__ ... #endif" around and 
compiled
locally and found that __STDC_LIB_EXT1__ was not defined, so the related
code  was not called. I'm afraid there's a problem with this
modification.

Am I using strtok_s wrong?

Thanks,
Jie Hai

no i overlooked that it is optional my fault sorry.

since there is no portable strtok_r i'm going to have to agree with others
that only places where you actually need reentrant strtok be converted to
strtok_r.

for windows i think we'll either need to introduce an abstracted strtok_r
name for portability or something in the rte_ namespace (dependent on
what other revieweres would prefer)

just as a follow up here maybe it would be optimal if we could use
strtok_s *if* we test that the toolchain makes it available and if not
provide a mapping of strtok_s -> strtok_r.

what do others think?

just a final follow up, i can see that we already have a rte_strerror
here to do the replace with reentrant dance. it is probably good to
follow the already established pattern for this and have a rte_strtok.

what do others think?

Please don't make wide assertions about multi-threading.
All these are only called from test_bbdev_vector_read which is single
threaded.

Please limit patches to places where you are sure the use is multi-threaded.

+1 to rte_strtok doing the reentrant dance for us.

If we had such an rte_strtok(), we could also generally disallow the use of strtok().

Good idea, I like this.

Hi, all maintainers,

Since the map of strtok_r to strtok_s with three patramaters has
been done in "rte_os_shim.h", I just include this file.
And the rte_strtok is defined as below.
My question is whether the
"strtok_s(s, stringlen, delim, save_ptr)" and
"strtok_s(str, delim, saveptr)" are compatible for C11.

And I check the glibc codes here,
https://sourceware.org/git/glibc.git
there is no definition of strtok_s, is strtok_s not in use?

If so, should we delayed processing for the C11 standard strtok_s 
function? That is, delete the "#ifdef __STDC_LIB_EXT1__...
#endif" part, but keep the extension of the four parameters for later 
use. Or keep the following change but never use stringlen as not null
until the function can be used.

What do you think?

Regardless of how it is done internally, I would not inline this helper.
This will minimise headaches with checks against toolchain/compiler
support in a DPDK header.

+1 to doing this, also in functions that are supposed to be single threaded; because it allows the addition to checkpatches.

[PATCH v4 00/13] replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

This patchset replaces strtok with strtok_r in app, example, lib
and drivers. And adds check for use of strtok in checkpatches.sh.

--
v4:
1. fix mispellings.
2. add Acked-bys and Reviewd-bys.
3. remove some patch and add new. 
v3:
1. fix compile error.
2. use strtok_r instead.
v2:
1. fix commit log.
2. add check in checkpatches.sh.
3. replace strtok_r with strtok_s.
4. add Acked-by.

[PATCH v4 01/13] dmadev: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

[PATCH v4 05/13] security: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

[PATCH v4 07/13] bus/fslmc: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

No reason to bother stable with this one. That function is only called
from RTE_INIT() which is a constructor.

Only called from RTE_INIT() so naturally single threaded.

Ok, but checkpatch keeps getting slower and slower with all this copy baset.
Could someone make it into a python script without so much copy/paste?

I recommend replacing all, based on:
1\ almost at no cost.
2\ reduce analysis costs, if don't we have to analyze the callers of strtok when you encounter it.

Yes but. The replacement should not go to stable.
One of the rules of stable is that changes should be minimized, and fixes should
not be accepted for things that can not ever happen with current code.

My assumption is that DPDK operates under similar rules as the Linux kernel.
Linux kernel rules are:

Rules on what kind of patches are accepted, and which ones are not, into the “-stable” tree:
    • It or an equivalent fix must already exist in Linux mainline (upstream).
    • It must be obviously correct and tested.
    • It cannot be bigger than 100 lines, with context.
    • It must follow the Documentation/process/submitting-patches.rst rules.
    • It must either fix a real bug that bothers people or just add a device ID. To elaborate on the former:
        ◦ It fixes a problem like an oops, a hang, data corruption, a real security issue, a hardware quirk, a build error (but not for things marked CONFIG_BROKEN), or some “oh, that’s not good” issue.
        ◦ Serious issues as reported by a user of a distribution kernel may also be considered if they fix a notable performance or interactivity issue. As these fixes are not as obvious and have a higher risk of a subtle regression they should only be submitted by a distribution kernel maintainer and include an addendum linking to a bugzilla entry if it exists and additional information on the user-visible impact.
        ◦ No “This could be a problem...” type of things like a “theoretical race condition”, unless an explanation of how the bug can be exploited is also provided.
        ◦ No “trivial” fixes without benefit for users (spelling changes, whitespace cleanups, etc).

- The current v4 series breaks compilation on Windows with clang.
http://mails.dpdk.org/archives/test-report/2024-November/819978.html

The reason is that some include of rte_os_shim.h are missing.

- grep shows that there are a number of missed places in drivers and
app, which contradicts the commitlog.
I don't like leaving some places with strtok while checkpatches.sh
warn on the rest.
And I think others were expecting too that the whole tree is fixed
after this series.

Re-reading the thread, were the changes on app/ dropped, following
comments from Stephen?
I understand his request was to remove the backport request (iow no
Cc: stable@dpdk.org in the commitlogs), not to drop the changes.

[PATCH v5 00/25]

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

This patchset replaces strtok with strtok_r in app, example, lib
and drivers. And adds check for use of strtok in checkpatches.sh.

--
v5:
1. remove CC stable for some patch.
2. replace strtok for all files.

v4:
1. fix mispellings.
2. add Acked-bys and Reviewd-bys.
3. remove some patch and add new. 
v3:
1. fix compile error.
2. use strtok_r instead.
v2:
1. fix commit log.
2. add check in checkpatches.sh.
3. replace strtok_r with strtok_s.
4. add Acked-by.

[PATCH v5 05/25] app/dma-perf: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

[PATCH v5 10/25] eal: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

[PATCH v5 16/25] common/cnxk: replace strtok with reentrant version

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

The strtok() is non-reentrant, it is better to replace it with a
reentrant version.

[PATCH v5 24/25] examples/vhost: replace strtok with reentrant version

race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

[PATCH v5 25/25] devtools: check for some reentrant function

[Jie Hai]

Multiple threads calling the same function may cause condition
race issues, which often leads to abnormal behavior and can cause
more serious vulnerabilities such as abnormal termination, denial
of service, and compromised data integrity.

This patch adds check in checkpatches.sh for strtok, which is
non-reentrant.

In case you did not notice, including rte_os_shim.h in examples breaks
compilation.
Too late for taking in rc2, I may consider in rc3 if the series is
fixed by then.


Thanks.
