[tip: x86/urgent] x86/resctrl: Remove superfluous kernfs_get() calls to prevent refcount leak

by tip-bot2 for Xiaochen Shen

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: fd8d9db3559a29fd737bcdb7c4fcbe1940caae34 Gitweb: https://git.kernel.org/tip/fd8d9db3559a29fd737bcdb7c4fcbe1940caae34 Author: Xiaochen Shen <xiaochen.shen(a)intel.com> AuthorDate: Sat, 31 Oct 2020 03:10:53 +08:00 Committer: Borislav Petkov <bp(a)suse.de> CommitterDate: Tue, 24 Nov 2020 12:03:04 +01:00 x86/resctrl: Remove superfluous kernfs_get() calls to prevent refcount leak Willem reported growing of kernfs_node_cache entries in slabtop when repeatedly creating and removing resctrl subdirectories as well as when repeatedly mounting and unmounting the resctrl filesystem. On resource group (control as well as monitoring) creation via a mkdir an extra kernfs_node reference is obtained to ensure that the rdtgroup structure remains accessible for the rdtgroup_kn_unlock() calls where it is removed on deletion. The kernfs_node reference count is dropped by kernfs_put() in rdtgroup_kn_unlock(). With the above explaining the need for one kernfs_get()/kernfs_put() pair in resctrl there are more places where a kernfs_node reference is obtained without a corresponding release. The excessive amount of reference count on kernfs nodes will never be dropped to 0 and the kernfs nodes will never be freed in the call paths of rmdir and umount. It leads to reference count leak and kernfs_node_cache memory leak. Remove the superfluous kernfs_get() calls and expand the existing comments surrounding the remaining kernfs_get()/kernfs_put() pair that remains in use. Superfluous kernfs_get() calls are removed from two areas: (1) In call paths of mount and mkdir, when kernfs nodes for "info", "mon_groups" and "mon_data" directories and sub-directories are created, the reference count of newly created kernfs node is set to 1. But after kernfs_create_dir() returns, superfluous kernfs_get() are called to take an additional reference. (2) kernfs_get() calls in rmdir call paths.

[tip: x86/urgent] x86/resctrl: Add necessary kernfs_put() calls to prevent refcount leak

by tip-bot2 for Xiaochen Shen

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 758999246965eeb8b253d47e72f7bfe508804b16 Gitweb: https://git.kernel.org/tip/758999246965eeb8b253d47e72f7bfe508804b16 Author: Xiaochen Shen <xiaochen.shen(a)intel.com> AuthorDate: Sat, 31 Oct 2020 03:11:28 +08:00 Committer: Borislav Petkov <bp(a)suse.de> CommitterDate: Tue, 24 Nov 2020 12:13:37 +01:00 x86/resctrl: Add necessary kernfs_put() calls to prevent refcount leak On resource group creation via a mkdir an extra kernfs_node reference is obtained by kernfs_get() to ensure that the rdtgroup structure remains accessible for the rdtgroup_kn_unlock() calls where it is removed on deletion. Currently the extra kernfs_node reference count is only dropped by kernfs_put() in rdtgroup_kn_unlock() while the rdtgroup structure is removed in a few other locations that lack the matching reference drop. In call paths of rmdir and umount, when a control group is removed, kernfs_remove() is called to remove the whole kernfs nodes tree of the control group (including the kernfs nodes trees of all child monitoring groups), and then rdtgroup structure is freed by kfree(). The rdtgroup structures of all child monitoring groups under the control group are freed by kfree() in free_all_child_rdtgrp(). Before calling kfree() to free the rdtgroup structures, the kernfs node of the control group itself as well as the kernfs nodes of all child monitoring groups still take the extra references which will never be dropped to 0 and the kernfs nodes will never be freed. It leads to reference count leak and kernfs_node_cache memory leak. For example, reference count leak is observed in these two cases: (1) mount -t resctrl resctrl /sys/fs/resctrl mkdir /sys/fs/resctrl/c1 mkdir /sys/fs/resctrl/c1/mon_groups/m1 umount /sys/fs/resctrl (2) mkdir /sys/fs/resctrl/c1 mkdir /sys/fs/resctrl/c1/mon_groups/m1 rmdir /sys/fs/resctrl/c1 The same reference count leak issue also exists in the error exit paths of mkdir in mkdir_rdt_prepare() and rdtgroup_mkdir_ctrl_mon(). Fix this issue by following changes to make sure the extra kernfs_node reference on rdtgroup is dropped before freeing the rdtgroup structure. (1) Introduce rdtgroup removal helper rdtgroup_remove() to wrap up kernfs_put() and kfree(). (2) Call rdtgroup_remove() in rdtgroup removal path where the rdtgroup structure is about to be freed by kfree(). (3) Call rdtgroup_remove() or kernfs_put() as appropriate in the error exit paths of mkdir where an extra reference is taken by kernfs_get().

[PATCH 1/6] arm64: pgtable: Fix pte_accessible()

by Will Deacon

pte_accessible() is used by ptep_clear_flush() to figure out whether TLB invalidation is necessary when unmapping pages for reclaim. Although our implementation is correct according to the architecture, returning true only for valid, young ptes in the absence of racing page-table modifications, this is in fact flawed due to lazy invalidation of old ptes in ptep_clear_flush_young() where we elide the expensive DSB instruction for completing the TLB invalidation. Rather than penalise the aging path, adjust pte_accessible() to return true for any valid pte, even if the access flag is cleared.

[PATCH v2] thermal/drivers/cpufreq_cooling: Update cpufreq_state only if state has changed

by zhuguangqing83＠gmail.com

From: Zhuguangqing <zhuguangqing(a)xiaomi.com> If state has not changed successfully and we updated cpufreq_state, next time when the new state is equal to cpufreq_state (not changed successfully last time), we will return directly and miss a freq_qos_update_request() that should have been.

[RESEND PATCH 03/19] pinctrl: sunxi: Always call chained_irq_{enter, exit} in sunxi_pinctrl_irq_handler

by Frank Lee

From: Yangtao Li <frank(a)allwinnertech.com> It is found on many allwinner soc that there is a low probability that the interrupt status cannot be read in sunxi_pinctrl_irq_handler. This will cause the interrupt status of a gpio bank to always be active on gic, preventing gic from responding to other spi interrupts correctly. So we should call the chained_irq_* each time enter sunxi_pinctrl_irq_handler().
