[PATCH openEuler-1.0-LTS 1/2] nbd: Fix memory leak in nbd_add_socket
by Yang Yingliang 07 Feb '21

07 Feb '21

From: Zheng Bin <zhengbin13(a)huawei.com> stable inclusion from linux-4.19.133 commit 306290bad932950adccfbf99c27b70c105c2c183 -------------------------------- [ Upstream commit 579dd91ab3a5446b148e7f179b6596b270dace46 ] When adding first socket to nbd, if nsock's allocation failed, the data structure member "config->socks" was reallocated, but the data structure member "config->num_connections" was not updated. A memory leak will occur then because the function "nbd_config_put" will free "config->socks" only when "config->num_connections" is not zero.

[PATCH openEuler-1.0-LTS 1/7] futex: Ensure the correct return value from futex_lock_pi()
by Yang Yingliang 04 Feb '21

04 Feb '21

From: Thomas Gleixner <tglx(a)linutronix.de> stable inclusion from linux-4.19.172 commit 72f38fffa4758b878f819f8a47761b3f03443f36 CVE: CVE-2021-3347 -------------------------------- commit 12bb3f7f1b03d5913b3f9d4236a488aa7774dfe9 upstream In case that futex_lock_pi() was aborted by a signal or a timeout and the task returned without acquiring the rtmutex, but is the designated owner of the futex due to a concurrent futex_unlock_pi() fixup_owner() is invoked to establish consistent state. In that case it invokes fixup_pi_state_owner() which in turn tries to acquire the rtmutex again. If that succeeds then it does not propagate this success to fixup_owner() and futex_lock_pi() returns -EINTR or -ETIMEOUT despite having the futex locked. Return success from fixup_pi_state_owner() in all cases where the current task owns the rtmutex and therefore the futex and propagate it correctly through fixup_owner(). Fixup the other callsite which does not expect a positive return value.

[PATCH openEuler-1.0-LTS 1/3] netfilter: clear skb->next in NF_HOOK_LIST()

[PATCH kernel-4.19 1/4] arm64: module: rework special section handling
by Yang Yingliang 04 Feb '21

04 Feb '21

From: Mark Rutland <mark.rutland(a)arm.com> mainline inclusion from mainline-v5.5-rc1 commit bd8b21d3dd661658addc1cd4cc869bab11d28596 category: bugfix bugzilla: 25285 CVE: NA -------------------------------- When we load a module, we have to perform some special work for a couple of named sections. To do this, we iterate over all of the module's sections, and perform work for each section we recognize. To make it easier to handle the unexpected absence of a section, and to make the section-specific logic easer to read, let's factor the section search into a helper. Similar is already done in the core module loader, and other architectures (and ideally we'd unify these in future). If we expect a module to have an ftrace trampoline section, but it doesn't have one, we'll now reject loading the module. When ARM64_MODULE_PLTS is selected, any correctly built module should have one (and this is assumed by arm64's ftrace PLT code) and the absence of such a section implies something has gone wrong at build time. Subsequent patches will make use of the new helper.

[PATCH openEuler-1.0-LTS] scsi: target: Fix XCOPY NAA identifier lookup
by Yang Yingliang 04 Feb '21

04 Feb '21

From: David Disseldorp <ddiss(a)suse.de> stable inclusion from linux-4.19.167 commit fff1180d24e68d697f98642d71444316036a81ff CVE: CVE-2020-28374 -------------------------------- commit 2896c93811e39d63a4d9b63ccf12a8fbc226e5e4 upstream. When attempting to match EXTENDED COPY CSCD descriptors with corresponding se_devices, target_xcopy_locate_se_dev_e4() currently iterates over LIO's global devices list which includes all configured backstores. This change ensures that only initiator-accessible backstores are considered during CSCD descriptor lookup, according to the session's se_node_acl LUN list. To avoid LUN removal race conditions, device pinning is changed from being configfs based to instead using the se_node_acl lun_ref.
