Created attachment 6082 [details] diff между оригинальным symbolserial.c и исправленным Ошибка была добавлена Johan Hovold в апреле 2013 года, как пишет автор - «All patches have been compile-tested only.» судя по http://permalink.gmane.org/gmane.linux.usb.general/85260 нужно провести инспекцию и других модулей :( На Sisyphus.

(В ответ на комментарий №4) > Также может иметь смысл повесить в bugzilla.kernel.org, но всё равно > обязательно в рассылку, как показывают предыдущие случаи. В bugzilla.kernel.org зафиксировал и ошибку, и патч. см. https://bugzilla.kernel.org/show_bug.cgi?id=74041 Не обессудьте - в рассылку мне писать слабО. (В ответ на комментарий №5) > см. https://bugzilla.kernel.org/show_bug.cgi?id=74041 О, там Грег глянул: https://bugzilla.kernel.org/show_bug.cgi?id=74041#c1 > Не обессудьте - в рассылку мне писать слабО. И всё-таки если ещё не поправили -- лучше написать; именно про linux-usb@ не скажу, но в linux-kernel@ подписка не требуется, нам отвечали с копией. На всё про всё с чтением документации и приведением патча в требуемый вид может уйти с полчаса; если всё-таки надо, но затруднительно, давайте попробуем вместе. Репорт 2014 года про ядро 3.14; flavour std-def удалён. Если воспроизводится на текущем kernel-image-6.x — просьба завести новый репорт. |
