[PATCH 5.4 0/3] CVE-2023-1611 Kernel: race between quota disable and quota assign ioctls in fs/btrfs/ioctl.c

by Harshvardhan Jha

The following series is a backport the fix of CVE-2023-1611 on stable 5.4. All pics were clean and no conflict resolution was needed. Commits "btrfs: qgroup: remove one-time use variables for quota_root checks" and "btrfs: qgroup: return ENOTCONN instead of EINVAL when quotas are not enabled" were added to get a clean pick for the fix "btrfs: fix race between quota disable and quota assign ioctls" These changes have been tested using the xfstests test-suite and no regressions were observed when compared to stable 5.4. Filipe Manana (1): btrfs: fix race between quota disable and quota assign ioctls Marcos Paulo de Souza (2): btrfs: qgroup: remove one-time use variables for quota_root checks btrfs: qgroup: return ENOTCONN instead of EINVAL when quotas are not enabled fs/btrfs/ioctl.c | 2 ++ fs/btrfs/qgroup.c | 55 +++++++++++++++++++++-------------------------- 2 files changed, 27 insertions(+), 30 deletions(-) -- 2.40.0

Such drivers specifically leave the state set to the default 'suspended' and the wake irq is thus never enabled at suspend. Add a new wake irq flag to track whether a dedicated wake irq has been enabled at runtime suspend and therefore must not be enabled at system suspend. Note that pm_runtime_enabled() can not be used as runtime PM is always disabled during late suspend.
