In the Linux kernel, the following vulnerability has been resolved: md: Fix missing release of 'active_io' for flush submit_flushes atomic_set(&mddev->flush_pending, 1); rdev_for_each_rcu(rdev, mddev) atomic_inc(&mddev->flush_pending); bi->bi_end_io = md_end_flush submit_bio(bi); /* flush io is done first */ md_end_flush if (atomic_dec_and_test(&mddev->flush_pending)) percpu_ref_put(&mddev->active_io) -> active_io is not released if (atomic_dec_and_test(&mddev->flush_pending)) -> missing release of active_io For consequence, mddev_suspend() will wait for 'active_io' to be zero forever. Fix this problem by releasing 'active_io' in submit_flushes() if 'flush_pending' is decreased to zero. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: md: Se corrigió la versión faltante de 'active_io' para descarga submit_flushes atomic_set(&mddev->flush_pending, 1); rdev_for_each_rcu(rdev, mddev) atomic_inc(&mddev->flush_pending); bi->bi_end_io = md_end_flush submit_bio(bi); /* purgar io se realiza primero */ md_end_flush if (atomic_dec_and_test(&mddev->flush_pending)) percpu_ref_put(&mddev->active_io) -> active_io no se publica si (atomic_dec_and_test(&mddev->flush_pending)) -> falta la versión de active_io para Como consecuencia, mddev_suspend() esperará a que 'active_io' sea cero para siempre. Solucione este problema liberando 'active_io' en submit_flushes() si 'flush_pending' se reduce a cero. • https://git.kernel.org/stable/c/f9f2d957a8ea93c73182aebf7de30935a58c027d https://git.kernel.org/stable/c/530cec617f5a8ba6f26bcbf0d64d75c951d17730 https://git.kernel.org/stable/c/c4c2345214b66e2505a26fd2ea58839dd7a1d48d https://git.kernel.org/stable/c/6b2ff10390b19a2364af622b6666b690443f9f3f https://git.kernel.org/stable/c/02dad157ba11064d073f5499dc33552b227d5d3a https://git.kernel.org/stable/c/11f81438927f84edfaaeb5d5f10856c3a1c1fc82 https://git.kernel.org/stable/c/855678ed8534518e2b428bcbcec695de9ba248e8 •
