[PATCH OLK-5.10] arm64/mpam: Fix use-after-free when deleting resource groups
by Zeng Heng 12 Mar '24

12 Mar '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I97KAV -------------------------------- Refer to the below commit: commit b8511ccc75c0 ("x86/resctrl: Fix use-after-free when deleting resource groups") Before removing rdtgroup, we need to refer to waitcount counter, otherwise when unmounting the resctrl file system or deleting ctrl_mon groups, and there were a waiter on resctrl system, then a use-after-free issue would occurs. Fix that by removing rdtgroup after checking the waitcount. Fixes: 3b856c03b36a ("arm64/mpam: remove kernfs_get() calls() and add kernfs_put() calls to prevent refcount leak") Signed-off-by: Zeng Heng <zengheng4(a)huawei.com> --- fs/resctrlfs.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/fs/resctrlfs.c b/fs/resctrlfs.c index e02e4769edc0..3f650eafccd0 100644 --- a/fs/resctrlfs.c +++ b/fs/resctrlfs.c @@ -485,7 +485,10 @@ static void free_all_child_rdtgrp(struct resctrl_group *rdtgrp) /* rmid may not be used */ rmid_free(sentry->mon.rmid); list_del(&sentry->mon.crdtgrp_list); - rdtgroup_remove(sentry); + if (atomic_read(&sentry->waitcount) != 0) + sentry->flags = RDT_DELETED; + else + rdtgroup_remove(sentry); } } @@ -519,7 +522,10 @@ static void rmdir_all_sub(void) kernfs_remove(rdtgrp->kn); list_del(&rdtgrp->resctrl_group_list); - rdtgroup_remove(rdtgrp); + if (atomic_read(&rdtgrp->waitcount) != 0) + rdtgrp->flags = RDT_DELETED; + else + rdtgroup_remove(rdtgrp); } /* Notify online CPUs to update per cpu storage and PQR_ASSOC MSR */ update_closid_rmid(cpu_online_mask, &resctrl_group_default); -- 2.25.1
