Sorry, I wasn't too sure about this and have not tried to contact the ESP team. As they own the code, I cannot change the license type, and basic googling suggested that we can use a mix of Apache2.0 and BSD as long as we keep the original license as is. Though some claim the resulting code has to be Apache2.0 as it is less permissive than BSD. > > This patch would seem to make hostap.git contents not comply with the > license requirements ("You must give any other recipients of the Work or > Derivative Works a copy of this License;" and the License text is not > included here), so even if I were to accept a different license to be > used, I could not accept something that would not meet the actual > license requirements. So, IIUC, using SPDX ID's implies license text, no? I can surely add the license file if that satisfies the needs. And also, I guess I should add a note at the top that I have modified these. > > > +// Lifted from https://stackoverflow.com/a/47117431 > > +char *strremove(char *str, const char *sub) > ... > > > +// Lifted from: https://stackoverflow.com/a/779960 > > +// You must free the result if result is non-NULL. > > +char *str_replace(char *orig, char *rep, char *with) > ... > > Can you please clarify what you mean with "lifted from"?

Yes, this is copied as is, and that post is licensed under https://creativecommons.org/licenses/by-sa/4.0/ (mentioned in the share link) and mentioning the source should satisfy the license IIUC. I can change "Lifted from" to "original source" and move them to a separate file with SPDX ID for those two functions? And anyways, these changes are not strictly needed, they were made to pass the hwsim tests.So, can use a simple switch case and avoid this algother. > > > diff --git a/tests/build/run-build-tests.sh b/tests/build/run-build-tests.sh > > @@ -8,13 +8,10 @@ popd > /dev/null > > echo "Build test directory: $DIR" > > echo > > > > -for i in build-hostapd-*.config; do > > - ./build-hostapd.sh $DIR $i > > -done > > - > > -for i in build-wpa_supplicant-*.config; do > > +for i in build-wpa_supplicant-mbedtls-3.1.0.config; do > > ./build-wpa_supplicant.sh $DIR $i > > done > > > > echo > > echo "Build test directory: $DIR" > > +cat $DIR/wpa_supplicant-mbedtls-3.1.0.log-* > > These changes are clearly not appropriate.

Okay. I will use $(error) as we do for other checks. > -- > Jouni Malinen PGP id EFC895FA _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
