[PATCH OLK-5.10] sched: Add static key for qos sched to improve performance
by Hui Tang 13 Jun '23

13 Jun '23

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7D76D -------------------------------- Add cmdline of 'noqossched' which is enable by default. Use the static key to reduce noise for multi level prio, smt expell and prio load balance.

[PATCH openEuler-22.03-LTS-SP2 v5 0/2] Add vhost net polling for high frequency TX mode
by Xu Kuohai 13 Jun '23

13 Jun '23

During high-frequency packet transmission, if vhost immediately notifies virtio driver after reading the virtio_queue empty, virtio driver will perform a kick after sending the next packet. However, if vhost waits a little longer, it could get the next packet sent by virtio driver without the need for virtio to perform a kick. This patch optimizes for this issue. If the TX interval recently recorded by vhost-net is within 50us, it is considered a high-frequency packet sending. At this time, after detecting the virtio_queue is empty, vhost-net will wait for new packets to arrive before notifing the virtio driver.

[PATCH OLK-5.10 v3 0/2] Add vhost net polling to suppress kick ratio
by Xu Kuohai 13 Jun '23

13 Jun '23

During high-frequency packet transmission, if vhost immediately notifies virtio driver after reading the virtio_queue empty, virtio driver will perform a kick after sending the next packet. However, if vhost waits a little longer, it could get the next packet sent by virtio driver without the need for virtio to perform a kick. This patch optimizes for this issue. If the TX interval recently recorded by vhost-net is within 50us, it is considered a high-frequency packet sending. At this time, after detecting the virtio_queue is empty, vhost-net will wait for new packets to arrive before notifing the virtio driver.

[PATCH OLK-5.10] proc: allow pid_revalidate() during LOOKUP_RCU
by Li Nan 13 Jun '23

13 Jun '23

From: Stephen Brennan <stephen.s.brennan(a)oracle.com> mainline inclusion from mainline-v5.16-rc1 commit da4d6b9cf80ae5b0083f640133b85b68b53b6497 category: bugfix bugzilla: 188892, https://gitee.com/openeuler/kernel/issues/I7CWJ7 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?i… ---------------------------------------- Problem Description: When running running ~128 parallel instances of TZ=/etc/localtime ps -fe >/dev/null on a 128CPU machine, the %sys utilization reaches 97%, and perf shows the following code path as being responsible for heavy contention on the d_lockref spinlock: walk_component() lookup_fast() d_revalidate() pid_revalidate() // returns -ECHILD unlazy_child() lockref_get_not_dead(&nd->path.dentry->d_lockref) <-- contention The reason is that pid_revalidate() is triggering a drop from RCU to ref path walk mode. All concurrent path lookups thus try to grab a reference to the dentry for /proc/, before re-executing pid_revalidate() and then stepping into the /proc/$pid directory. Thus there is huge spinlock contention. This patch allows pid_revalidate() to execute in RCU mode, meaning that the path lookup can successfully enter the /proc/$pid directory while still in RCU mode. Later on, the path lookup may still drop into ref mode, but the contention will be much reduced at this point. By applying this patch, %sys utilization falls to around 85% under the same workload, and the number of ps processes executed per unit time increases by 3x-4x. Although this particular workload is a bit contrived, we have seen some large collections of eager monitoring scripts which produced similarly high %sys time due to contention in the /proc directory. As a result this patch, Al noted that several procfs methods which were only called in ref-walk mode could now be called from RCU mode. To ensure that this patch is safe, I audited all the inode get_link and permission() implementations, as well as dentry d_revalidate() implementations, in fs/proc. The purpose here is to ensure that they either are safe to call in RCU (i.e. don't sleep) or correctly bail out of RCU mode if they don't support it. My analysis shows that all at-risk procfs methods are safe to call under RCU, and thus this patch is safe. Procfs RCU-walk Analysis: This analysis is up-to-date with 5.15-rc3. When called under RCU mode, these functions have arguments as follows: * get_link() receives a NULL dentry pointer when called in RCU mode. * permission() receives MAY_NOT_BLOCK in the mode parameter when called from RCU. * d_revalidate() receives LOOKUP_RCU in flags. For the following functions, either they are trivially RCU safe, or they explicitly bail at the beginning of the function when they run: proc_ns_get_link (bails out) proc_get_link (RCU safe) proc_pid_get_link (bails out) map_files_d_revalidate (bails out) map_misc_d_revalidate (bails out) proc_net_d_revalidate (RCU safe) proc_sys_revalidate (bails out, also not under /proc/$pid) tid_fd_revalidate (bails out) proc_sys_permission (not under /proc/$pid) The remainder of the functions require a bit more detail: * proc_fd_permission: RCU safe. All of the body of this function is under rcu_read_lock(), except generic_permission() which declares itself RCU safe in its documentation string. * proc_self_get_link uses GFP_ATOMIC in the RCU case, so it is RCU aware and otherwise looks safe. The same is true of proc_thread_self_get_link. * proc_map_files_get_link: calls ns_capable, which calls capable(), and thus calls into the audit code (see note #1 below). The remainder is just a call to the trivially safe proc_pid_get_link(). * proc_pid_permission: calls ptrace_may_access(), which appears RCU safe, although it does call into the "security_ptrace_access_check()" hook, which looks safe under smack and selinux. Just the audit code is of concern. Also uses get_task_struct() and put_task_struct(), see note #2 below. * proc_tid_comm_permission: Appears safe, though calls put_task_struct (see note #2 below). Note #1: Most of the concern of RCU safety has centered around the audit code. However, since b17ec22fb339 ("selinux: slow_avc_audit has become non-blocking"), it's safe to call this code under RCU. So all of the above are safe by my estimation. Note #2: get_task_struct() and put_task_struct(): The majority of get_task_struct() is under RCU read lock, and in any case it is a simple increment. But put_task_struct() is complex, given that it could at some point free the task struct, and this process has many steps which I couldn't manually verify. However, several other places call put_task_struct() under RCU, so it appears safe to use here too (see kernel/hung_task.c:165 or rcu/tree-stall.h:296) Patch description: pid_revalidate() drops from RCU into REF lookup mode. When many threads are resolving paths within /proc in parallel, this can result in heavy spinlock contention on d_lockref as each thread tries to grab a reference to the /proc dentry (and drop it shortly thereafter). Investigation indicates that it is not necessary to drop RCU in pid_revalidate(), as no RCU data is modified and the function never sleeps. So, remove the LOOKUP_RCU check.

[OLK-5.10 1/1] proc: allow pid_revalidate() during LOOKUP_RCU
by Li Nan 12 Jun '23

12 Jun '23

From: Stephen Brennan <stephen.s.brennan(a)oracle.com> mainline inclusion from mainline-v5.16-rc1 commit da4d6b9cf80ae5b0083f640133b85b68b53b6497 category: bugfix bugzilla: 188892, https://gitee.com/openeuler/kernel/issues/I7CWJ7 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?i… ---------------------------------------- Problem Description: When running running ~128 parallel instances of TZ=/etc/localtime ps -fe >/dev/null on a 128CPU machine, the %sys utilization reaches 97%, and perf shows the following code path as being responsible for heavy contention on the d_lockref spinlock: walk_component() lookup_fast() d_revalidate() pid_revalidate() // returns -ECHILD unlazy_child() lockref_get_not_dead(&nd->path.dentry->d_lockref) <-- contention The reason is that pid_revalidate() is triggering a drop from RCU to ref path walk mode. All concurrent path lookups thus try to grab a reference to the dentry for /proc/, before re-executing pid_revalidate() and then stepping into the /proc/$pid directory. Thus there is huge spinlock contention. This patch allows pid_revalidate() to execute in RCU mode, meaning that the path lookup can successfully enter the /proc/$pid directory while still in RCU mode. Later on, the path lookup may still drop into ref mode, but the contention will be much reduced at this point. By applying this patch, %sys utilization falls to around 85% under the same workload, and the number of ps processes executed per unit time increases by 3x-4x. Although this particular workload is a bit contrived, we have seen some large collections of eager monitoring scripts which produced similarly high %sys time due to contention in the /proc directory. As a result this patch, Al noted that several procfs methods which were only called in ref-walk mode could now be called from RCU mode. To ensure that this patch is safe, I audited all the inode get_link and permission() implementations, as well as dentry d_revalidate() implementations, in fs/proc. The purpose here is to ensure that they either are safe to call in RCU (i.e. don't sleep) or correctly bail out of RCU mode if they don't support it. My analysis shows that all at-risk procfs methods are safe to call under RCU, and thus this patch is safe. Procfs RCU-walk Analysis: This analysis is up-to-date with 5.15-rc3. When called under RCU mode, these functions have arguments as follows: * get_link() receives a NULL dentry pointer when called in RCU mode. * permission() receives MAY_NOT_BLOCK in the mode parameter when called from RCU. * d_revalidate() receives LOOKUP_RCU in flags. For the following functions, either they are trivially RCU safe, or they explicitly bail at the beginning of the function when they run: proc_ns_get_link (bails out) proc_get_link (RCU safe) proc_pid_get_link (bails out) map_files_d_revalidate (bails out) map_misc_d_revalidate (bails out) proc_net_d_revalidate (RCU safe) proc_sys_revalidate (bails out, also not under /proc/$pid) tid_fd_revalidate (bails out) proc_sys_permission (not under /proc/$pid) The remainder of the functions require a bit more detail: * proc_fd_permission: RCU safe. All of the body of this function is under rcu_read_lock(), except generic_permission() which declares itself RCU safe in its documentation string. * proc_self_get_link uses GFP_ATOMIC in the RCU case, so it is RCU aware and otherwise looks safe. The same is true of proc_thread_self_get_link. * proc_map_files_get_link: calls ns_capable, which calls capable(), and thus calls into the audit code (see note #1 below). The remainder is just a call to the trivially safe proc_pid_get_link(). * proc_pid_permission: calls ptrace_may_access(), which appears RCU safe, although it does call into the "security_ptrace_access_check()" hook, which looks safe under smack and selinux. Just the audit code is of concern. Also uses get_task_struct() and put_task_struct(), see note #2 below. * proc_tid_comm_permission: Appears safe, though calls put_task_struct (see note #2 below). Note #1: Most of the concern of RCU safety has centered around the audit code. However, since b17ec22fb339 ("selinux: slow_avc_audit has become non-blocking"), it's safe to call this code under RCU. So all of the above are safe by my estimation. Note #2: get_task_struct() and put_task_struct(): The majority of get_task_struct() is under RCU read lock, and in any case it is a simple increment. But put_task_struct() is complex, given that it could at some point free the task struct, and this process has many steps which I couldn't manually verify. However, several other places call put_task_struct() under RCU, so it appears safe to use here too (see kernel/hung_task.c:165 or rcu/tree-stall.h:296) Patch description: pid_revalidate() drops from RCU into REF lookup mode. When many threads are resolving paths within /proc in parallel, this can result in heavy spinlock contention on d_lockref as each thread tries to grab a reference to the /proc dentry (and drop it shortly thereafter). Investigation indicates that it is not necessary to drop RCU in pid_revalidate(), as no RCU data is modified and the function never sleeps. So, remove the LOOKUP_RCU check.

[PATCH OLK-5.10] vhost_net: Suppress kick ratio when fast TX detected
by Xu Kuohai 12 Jun '23

12 Jun '23

hulk inclusion category: feature bugzilla: NA CVE: N/A ---------------------------------------------------- During high-frequency packet transmission, if vhost immediately notifies virtio driver after reading the virtio_queue empty, virtio driver will perform a kick after sending the next packet. However, if vhost waits a little longer, it could get the next packet sent by virtio driver without the need for virtio to perform a kick. This patch optimizes for this issue. If the TX interval recently recorded by vhost-net is within 50us, it is considered a high-frequency packet sending. At this time, after detecting the virtio_queue is empty, vhost-net will wait for new packets to arrive before notifing the virtio driver.

[PATCH openEuler-1.0-LTS 1/3] dccp/tcp: Avoid negative sk_forward_alloc by ipv6_pinfo.pktoptions.
by Yongqiang Liu 12 Jun '23

12 Jun '23

From: Kuniyuki Iwashima <kuniyu(a)amazon.com> stable inclusion from stable-v4.19.273 commit 28a1742fcc1d8692e9090864373aa77fb3a0c8fd category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6TPN9 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit ca43ccf41224b023fc290073d5603a755fd12eed upstream. Eric Dumazet pointed out [0] that when we call skb_set_owner_r() for ipv6_pinfo.pktoptions, sk_rmem_schedule() has not been called, resulting in a negative sk_forward_alloc. We add a new helper which clones a skb and sets its owner only when sk_rmem_schedule() succeeds. Note that we move skb_set_owner_r() forward in (dccp|tcp)_v6_do_rcv() because tcp_send_synack() can make sk_forward_alloc negative before ipv6_opt_accepted() in the crossed SYN-ACK or self-connect() cases.

[PATCH openEuler-22.03-LTS-SP2] genirq: Increase the number of IRQ descriptors
by Kunkun Jiang 12 Jun '23

12 Jun '23

virt inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7BQMW CVE: NA ----------------------------------------------------------------- The deafault value of NR_IRQS is not sufficient to support GICv4.1 features and ~56K LPIs. This parameter would be too small for certain server platforms where it has many IO devices and is capable of direct injection of vSGI and vLPI features. Currently, maximum of 64 + 8192 (IRQ_BITMAP_BITS) IRQ descriptors are allowed. The vCPU creation fails after reaching count ~400 with kvm-arm.vgic_v4_enable=1. This patch increases NR_IRQS to 1^19 to cover 56K LPIs and 262144 vSGIs (16vPEs x 16). ------------------------------------------------------------------ Tips: This is a temporary fix[1], but it has been able to solve the problem. The latest upstream version[2] depends on the 'maple tree', which is inappropriately introduced to the current kernel. ------------------------------------------------------------------- Another Tips: According to Chao Liu and Chang Liao's suggestion, modifying IRQ_BITMAP_BITS can achieve the same effect with less impact. Compared with solution[2], solution[1] has a disadvantage: the memory foot print increases as the number of VMs increases.

[PATCH OLK-5.10 1/6] memcg: add page type to memory.reclaim interface
by Liu Shixin 10 Jun '23

10 Jun '23

Add anon/file to memory.reclaim interface to limit only reclaim one type pages. The lru algorithm can reclaim cold pages and balance between file and anon. But it didn't consider the speed of backend device. For example, if there is zram device, reclaim anon pages might has less impact on performance. So extend memory.reclaim interface to reclaim one type pages. Usage: "echo <size> type=anon > memory.reclaim" "echo <size> type=file > memory.reclaim" Also compatible with the previous format.

[openEuler/rdma-core v4] libhns: Support user to choose using UD sl or pktype to adapt MPI APP
by Chengchang Tang 09 Jun '23

09 Jun '23

From: Junxian Huang <huangjunxian6(a)hisilicon.com> driver inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/rdma-core/issues/I7A5YM --------------------------------------------------------------- According to Annex17_RoCEv2 (A17.4.5.2), for RoCEv2 UD, a CQE should carry a flag that indicates if the received frame is an IPv4, IPv6 or RoCE packet. But currently, the values of the flag corresponding to these packet types haven't been defined yet in WC. In UCX, 'sl' in ibv_wc for UD is used as the packet type flag, and the packet type values have already been defined in the UCX patch of https://github.com/openucx/ucx/commit/ed28845b88633e65d64fce8ec880060aa61bd… Therefore, to adapt UCX, add a create flag to hnsdv_create_qp() to allow users to choose whether they use 'sl' in ibv_wc as service level or packet type for UD. For the latter, obtain and translate the packet type from CQE and fill it to 'sl' in ibv_wc.

[PATCH openEuler-1.0-LTS 01/21] udp: Call inet6_destroy_sock() in setsockopt(IPV6_ADDRFORM).
by Yongqiang Liu 08 Jun '23

08 Jun '23

From: Kuniyuki Iwashima <kuniyu(a)amazon.com> stable inclusion from stable-v4.19.282 commit 9577d9f0fbf1eea95f61b02627572c401499aa32 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7BZ5U CVE: NA -------------------------------- commit 21985f43376cee092702d6cb963ff97a9d2ede68 upstream. Commit 4b340ae20d0e ("IPv6: Complete IPV6_DONTFRAG support") forgot to add a change to free inet6_sk(sk)->rxpmtu while converting an IPv6 socket into IPv4 with IPV6_ADDRFORM. After conversion, sk_prot is changed to udp_prot and ->destroy() never cleans it up, resulting in a memory leak. This is due to the discrepancy between inet6_destroy_sock() and IPV6_ADDRFORM, so let's call inet6_destroy_sock() from IPV6_ADDRFORM to remove the difference. However, this is not enough for now because rxpmtu can be changed without lock_sock() after commit 03485f2adcde ("udpv6: Add lockless sendmsg() support"). We will fix this case in the following patch. Note we will rename inet6_destroy_sock() to inet6_cleanup_sock() and remove unnecessary inet6_destroy_sock() calls in sk_prot->destroy() in the future.

[PATCH openEuler-1.0-LTS 1/2] fs: hfsplus: fix UAF issue in hfsplus_put_super

From: Dongliang Mu <mudongliangabcd(a)gmail.com> stable inclusion from stable-v4.19.273 commit e226f1fdcee1ca6e68233b132718deb578a84e38 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I79LIO CVE: CVE-2023-2985 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit 07db5e247ab5858439b14dd7cc1fe538b9efcf32 upstream. The current hfsplus_put_super first calls hfs_btree_close on sbi->ext_tree, then invokes iput on sbi->hidden_dir, resulting in an use-after-free issue in hfsplus_release_folio. As shown in hfsplus_fill_super, the error handling code also calls iput before hfs_btree_close. To fix this error, we move all iput calls before hfsplus_btree_close. Note that this patch is tested on Syzbot.

by Long Li 08 Jun '23

08 Jun '23

From: Dongliang Mu <mudongliangabcd(a)gmail.com> stable inclusion from stable-v5.10.167 commit ef7d71d7bd57b8b7fe514e459927696c1c6d1047 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I79LIO CVE: CVE-2023-2985 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit 07db5e247ab5858439b14dd7cc1fe538b9efcf32 upstream. The current hfsplus_put_super first calls hfs_btree_close on sbi->ext_tree, then invokes iput on sbi->hidden_dir, resulting in an use-after-free issue in hfsplus_release_folio. As shown in hfsplus_fill_super, the error handling code also calls iput before hfs_btree_close. To fix this error, we move all iput calls before hfsplus_btree_close. Note that this patch is tested on Syzbot.

[PATCH OLK-5.10 0/2] bugfix the lost interruption problem after live migration
by liulongfang 08 Jun '23

08 Jun '23

From: JiangShui Yang <yangjiangshui(a)h-partners.com> The problem of service interruption and loss may be triggered during live migration. In order to ensure normal business, it is necessary to resend an interrupt in the live migration driver. And in the QM service driver, it is guaranteed that the retransmission interrupt can be received normally.

[PATCH PATCH OLK-5.10 0/2] bugfix the lost interruption problem after live migration
by liulongfang 08 Jun '23

08 Jun '23

The problem of service interruption and loss may be triggered during live migration. In order to ensure normal business, it is necessary to resend an interrupt in the live migration driver. And in the QM service driver, it is guaranteed that the retransmission interrupt can be received normally.

[PATCH OLK-5.10] mm: page_counter: remove unneeded atomic ops for low/min
by Peng Zhang 07 Jun '23

07 Jun '23

From: Shakeel Butt <shakeelb(a)google.com> mainline inclusion from mainline-v6.1-rc1 commit cfdab60bfa66b2dc0391c9e405b8af6039924cd4 category: perf bugzilla: https://gitee.com/openeuler/kernel/issues/I7BHGR CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Patch series "memcg: optimize charge codepath", v2. Recently Linux networking stack has moved from a very old per socket pre-charge caching to per-cpu caching to avoid pre-charge fragmentation and unwarranted OOMs. One impact of this change is that for network traffic workloads, memcg charging codepath can become a bottleneck. The kernel test robot has also reported this regression[1]. This patch series tries to improve the memcg charging for such workloads. This patch series implement three optimizations: (A) Reduce atomic ops in page counter update path. (B) Change layout of struct page_counter to eliminate false sharing between usage and high.

To evaluate the impact of these optimizations, on a 72 CPUs machine, we ran the following workload in root memcg and then compared with scenario where the workload is run in a three level of cgroup hierarchy with top level having min and low setup appropriately. $ netserver -6 # 36 instances of netperf with following params $ netperf -6 -H ::1 -l 60 -t TCP_SENDFILE -- -m 10K Results (average throughput of netperf): 1. root memcg 21694.8 Mbps 2. 6.0-rc1 10482.7 Mbps (-51.6%) 3. 6.0-rc1 + (A) 14542.5 Mbps (-32.9%) 4. 6.0-rc1 + (B) 12413.7 Mbps (-42.7%) 5. 6.0-rc1 + (C) 17063.7 Mbps (-21.3%) 6. 6.0-rc1 + (A+B+C) 20120.3 Mbps (-7.2%) With all three optimizations, the memcg overhead of this workload has been reduced from 51.6% to just 7.2%. [1] https://lore.kernel.org/linux-mm/20220619150456.GB34471@xsang-OptiPlex-9020/ This patch (of 3): For cgroups using low or min protections, the function propagate_protected_usage() was doing an atomic xchg() operation irrespectively. We can optimize out this atomic operation for one specific scenario where the workload is using the protection (i.e. min > 0) and the usage is above the protection (i.e. usage > min). This scenario is actually very common where the users want a part of their workload to be protected against the external reclaim. Though this optimization does introduce a race when the usage is around the protection and concurrent charges and uncharged trip it over or under the protection. In such cases, we might see lower effective protection but the subsequent charge/uncharge will correct it. To evaluate the impact of this optimization, on a 72 CPUs machine, we ran the following workload in a three level of cgroup hierarchy with top level having min and low setup appropriately to see if this optimization is effective for the mentioned case. $ netserver -6 # 36 instances of netperf with following params $ netperf -6 -H ::1 -l 60 -t TCP_SENDFILE -- -m 10K Results (average throughput of netperf): Without (6.0-rc1) 10482.7 Mbps With patch 14542.5 Mbps (38.7% improvement) With the patch, the throughput improved by 38.7% Link: https://lkml.kernel.org/r/20220825000506.239406-1-shakeelb@google.com Link: https://lkml.kernel.org/r/20220825000506.239406-2-shakeelb@google.com Signed-off-by: Shakeel Butt <shakeelb(a)google.com> Reported-by: kernel test robot <oliver.sang(a)intel.com> Acked-by: Soheil Hassas Yeganeh <soheil(a)google.com> Reviewed-by: Feng Tang <feng.tang(a)intel.com> Acked-by: Roman Gushchin <roman.gushchin(a)linux.dev> Acked-by: Michal Hocko <mhocko(a)suse.com> Cc: Eric Dumazet <edumazet(a)google.com> Cc: Johannes Weiner <hannes(a)cmpxchg.org> Cc: "Michal Koutný" <mkoutny(a)suse.com> Cc: Muchun Song <songmuchun(a)bytedance.com> Cc: Oliver Sang <oliver.sang(a)intel.com> Cc: Soheil Hassas Yeganeh <soheil(a)google.com> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Signed-off-by: ZhangPeng <zhangpeng362(a)huawei.com> --- mm/page_counter.c | 13 ++++++------- 1 file changed, 6 insertions(+), 7 deletions(-) diff --git a/mm/page_counter.c b/mm/page_counter.c index 6d8715e3255d..e67e54e836b1 100644 --- a/mm/page_counter.c +++ b/mm/page_counter.c @@ -17,24 +17,23 @@ static void propagate_protected_usage(struct page_counter *c, unsigned long usage) { unsigned long protected, old_protected; - unsigned long low, min; long delta; if (!c->parent) return; - min = READ_ONCE(c->min); - if (min || atomic_long_read(&c->min_usage)) { - protected = min(usage, min); + protected = min(usage, READ_ONCE(c->min)); + old_protected = atomic_long_read(&c->min_usage); + if (protected != old_protected) { old_protected = atomic_long_xchg(&c->min_usage, protected); delta = protected - old_protected; if (delta) atomic_long_add(delta, &c->parent->children_min_usage); } - low = READ_ONCE(c->low); - if (low || atomic_long_read(&c->low_usage)) { - protected = min(usage, low); + protected = min(usage, READ_ONCE(c->low)); + old_protected = atomic_long_read(&c->low_usage); + if (protected != old_protected) { old_protected = atomic_long_xchg(&c->low_usage, protected); delta = protected - old_protected; if (delta) -- 2.25.1

[backport for 5.10.y] The O_TMPFILE creation implementation creates a specific order of operations for inode allocation/freeing and unlinked list modification. Currently both are serialised by the AGI, so the order doesn't strictly matter as long as the are both in the same transaction. However, if we want to move the unlinked list insertions largely out from under the AGI lock, then we have to be concerned about the order in which we do unlinked list modification operations. O_TMPFILE creation tells us this order is inode allocation/free, then unlinked list modification. Change xfs_ifree() to use this same ordering on unlinked list removal. This way we always guarantee that when we enter the iunlinked list removal code from this path, we already have the AGI locked and we don't have to worry about lock nesting AGI reads inside unlink list locks because it's already locked and attached to the transaction. We can do this safely as the inode freeing and unlinked list removal are done in the same transaction and hence are atomic operations with respect to log recovery.

[PATCH OLK-5.10] tcp/dccp: Add another way to allocate local ports in connect()
by Liu Jian 05 Jun '23

05 Jun '23

From: Lu Wei <luwei32(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I7AO8G CVE: NA -------------------------------- Commit 07f4c90062f8 ("tcp/dccp: try to not exhaust ip_local_port_range in connect()") allocates even ports for connect() first while leaving odd ports for bind() and this works well in busy servers. But this strategy causes severe performance degradation in busy clients. when a client has used more than half of the local ports setted in proc/sys/net/ipv4/ip_local_port_range, if this client trys to connect to a server again, the connect time increases rapidly since it will traverse all the even ports though they are exhausted. So this path provides another strategy by introducing a system option: local_port_allocation. If it is a busy client, users should set it to 1 to use sequential allocation while it should be set to 0 in other situations. Its default value is 0.

[PATCH OLK-5.10] ethtool: ioctl: fix potential NULL deref in ethtool_set_coalesce()

From: Julian Wiedmann <jwi(a)linux.ibm.com> mainline inclusion from mainline-v5.16-rc3 commit 0276af2176c78771da7f311621a25d7608045827 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7A2A0 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- ethtool_set_coalesce() now uses both the .get_coalesce() and .set_coalesce() callbacks. But the check for their availability is buggy, so changing the coalesce settings on a device where the driver provides only _one_ of the callbacks results in a NULL pointer dereference instead of an -EOPNOTSUPP. Fix the condition so that the availability of both callbacks is ensured. This also matches the netlink code. Note that reproducing this requires some effort - it only affects the legacy ioctl path, and needs a specific combination of driver options: - have .get_coalesce() and .coalesce_supported but no .set_coalesce(), or - have .set_coalesce() but no .get_coalesce(). Here eg. ethtool doesn't cause the crash as it first attempts to call ethtool_get_coalesce() and bails out on error.

Their offsets in struct ext4_inode_info is 696 and 744, so when the address of ext4_inode_info after L3 aligned, it may occur L3 false sharing in the following condition: [0x00 ~ 0x10] false sharing [0x18 ~ 0x40] no false sharing [0x48 ~ 0x80] false sharing Change the offset of 'vfs_inode' from 320 to 360 in ext4_inode_info and make the address of ext4_inode_info L3 aligned, so the offset of host and i_mmap_rwsem in ext4_inode_info is changed to 736 and 784, it can make them in different L3 to avoid false sharing. ./Run -c 96 -i 3 execl Before this patch: System Benchmarks Partial Index BASELINE RESULT INDEX Execl Throughput 43.0 24238.0 5636.8 ======== System Benchmarks Index Score (Partial Only) 5636.8 After this patch: System Benchmarks Partial Index BASELINE RESULT INDEX Execl Throughput 43.0 29363.7 6828.8 ======== System Benchmarks Index Score (Partial Only) 6828.8 Yang Yingliang (2): ext4: mitigatin cacheline false sharing in struct ext4_inode_info enable MITIGATION_FALSE_SHARING by default arch/arm64/configs/openeuler_defconfig | 1 + arch/x86/configs/openeuler_defconfig | 1 + fs/ext4/Kconfig | 9 +++++++++ fs/ext4/ext4.h | 5 +++++ fs/ext4/super.c | 4 ++++ 5 files changed, 20 insertions(+) -- 2.33.0

[PATCH openEuler-22.03-LTS] arm64: kdump: Avoid reserving low memory repeatedly
by Li Huafei 31 May '23

31 May '23

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6Y5Y1 ------------------------------- We call reserve_crashkernel_high() before map_mem() to reserve high memory in advance, which in turn can avoid using page level mapping for all memory above 4G to optimize performance. And after reserve_crashkernel_high(), reserve_crashkernel_low() is also needed to reserve low memory. But when the system RAM is less than 4G, the memory reserved by reserve_crashkernel_high() is already low memory (less than 4G), reserve_crashkernel_low() may reserve low memory again and the memory it reserves may be higher than that reserved by reserve_crashkernel_high(). Looking at /proc/iomem would have: # cat /proc/iomem | grep -i crash 65400000-953fffff : Crash kernel ==> crashk_res a7800000-b77fffff : Crash kernel ==> crashk_res_low At this point kexec-tools will incorrectly use the second memory segment for the kdump kernel image load, causing the kernel load address check to fail during kexec load (see sanity_check_segment_list()). When the memory reserved by reserve_crashkernel_high() meets the low memory requirement, reserve_crashkernel_low() is no longer called to reserve memory and avoid introducing problems with duplicate reservations.

[PATCH openEuler-1.0-LTS] x86/pm: Fix false positive kmemleak report in msr_build_context()
by Yongqiang Liu 30 May '23

30 May '23

From: Matthieu Baerts <matthieu.baerts(a)tessares.net> mainline inclusion from mainline-v5.19-rc1 commit b0b592cf08367719e1d1ef07c9f136e8c17f7ec3 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I78RHX CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Since e2a1256b17b1 ("x86/speculation: Restore speculation related MSRs during S3 resume") kmemleak reports this issue: unreferenced object 0xffff888009cedc00 (size 256): comm "swapper/0", pid 1, jiffies 4294693823 (age 73.764s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 48 00 00 00 00 00 00 00 ........H....... 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: msr_build_context (include/linux/slab.h:621) pm_check_save_msr (arch/x86/power/cpu.c:520) do_one_initcall (init/main.c:1298) kernel_init_freeable (init/main.c:1370) kernel_init (init/main.c:1504) ret_from_fork (arch/x86/entry/entry_64.S:304) Reproducer: - boot the VM with a debug kernel config (see https://github.com/multipath-tcp/mptcp_net-next/issues/268) - wait ~1 minute - start a kmemleak scan The root cause here is alignment within the packed struct saved_context (from suspend_64.h). Kmemleak only searches for pointers that are aligned (see how pointers are scanned in kmemleak.c), but pahole shows that the saved_msrs struct member and all members after it in the structure are unaligned: struct saved_context { struct pt_regs regs; /* 0 168 */ /* --- cacheline 2 boundary (128 bytes) was 40 bytes ago --- */ u16 ds; /* 168 2 */ ... u64 misc_enable; /* 232 8 */ bool misc_enable_saved; /* 240 1 */ /* Note below odd offset values for the remainder of this struct */ struct saved_msrs saved_msrs; /* 241 16 */ /* --- cacheline 4 boundary (256 bytes) was 1 bytes ago --- */ long unsigned int efer; /* 257 8 */ u16 gdt_pad; /* 265 2 */ struct desc_ptr gdt_desc; /* 267 10 */ u16 idt_pad; /* 277 2 */ struct desc_ptr idt; /* 279 10 */ u16 ldt; /* 289 2 */ u16 tss; /* 291 2 */ long unsigned int tr; /* 293 8 */ long unsigned int safety; /* 301 8 */ long unsigned int return_address; /* 309 8 */ /* size: 317, cachelines: 5, members: 25 */ /* last cacheline: 61 bytes */ } __attribute__((__packed__)); Move misc_enable_saved to the end of the struct declaration so that saved_msrs fits in before the cacheline 4 boundary. The comment above the saved_context declaration says to fix wakeup_64.S file and __save/__restore_processor_state() if the struct is modified: it looks like all the accesses in wakeup_64.S are done through offsets which are computed at build-time. Update that comment accordingly. At the end, the false positive kmemleak report is due to a limitation from kmemleak but it is always good to avoid unaligned members for optimisation purposes.

[PATCH openEuler-1.0-LTS 1/2] drm: Fix use-after-free read in drm_getunique()
by Yongqiang Liu 30 May '23

30 May '23

From: Desmond Cheong Zhi Xi <desmondcheongzx(a)gmail.com> stable inclusion from stable-v4.19.195 commit 7d233ba700ceb593905ea82b42dadb4ec8ef85e9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I52XND CVE: CVE-2022-1280 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit b436acd1cf7fac0ba987abd22955d98025c80c2b upstream. There is a time-of-check-to-time-of-use error in drm_getunique() due to retrieving file_priv->master prior to locking the device's master mutex. An example can be seen in the crash report of the use-after-free error found by Syzbot: https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f8… In the report, the master pointer was used after being freed. This is because another process had acquired the device's master mutex in drm_setmaster_ioctl(), then overwrote fpriv->master in drm_new_set_master(). The old value of fpriv->master was subsequently freed before the mutex was unlocked. To fix this, we lock the device's master mutex before retrieving the pointer from from fpriv->master. This patch passes the Syzbot reproducer test.

This will lead to error or inaccurate data since before we enable the counters the counter's still counting for the event used in last perf session.

It also avoids the potential KASAN / syzkaller failure, as a bonus.

[OLK-5.10 0/8] Add support for HiSilicon UC/H60PA/PAv3 PMU driver
by Junhao He 23 May '23

23 May '23

1. Compared with the PAv2 PMU, the PAv3 PMU has different event IDs and definitions. The version number in the version register is used to distinguish the event IDs and definitions in the driver. 2. The H60PA PMU and PA are two different devices. The H60PA PMU supports higher bandwidth, and the PA PMU delay is relatively low. Different HIDs are used to distinguish the delay. 3. Each cluster is integrated with a unified cache (UC) PMU, which provides consistency between NUMA and UMA domains. It sits between L2 and the memory system.

The ondisk AGF has a higher LSN than the recovered log item. xlog_recover_buf_commit_pass2 reads the buffer, compares the LSNs, and decides to skip replay because the ondisk buffer appears to be newer. Unfortunately, the ondisk buffer is corrupt, but recovery just read the buffer with no buffer ops specified: error = xfs_buf_read(mp->m_ddev_targp, buf_f->blf_blkno, buf_f->blf_len, buf_flags, &bp, NULL); Skipping the buffer leaves its contents in memory unverified. This sets us up for a kernel crash because xfs_refcount_recover_cow_leftovers reads the buffer (which is still around in XBF_DONE state, so no read verification) and creates a refcountbt cursor of height 32. This is impossible so we run off the end of the cursor object and crash. Fix this by invoking the verifier on all skipped buffers and aborting log recovery if the ondisk buffer is corrupt. It might be smarter to force replay the log item atop the buffer and then see if it'll pass the write verifier (like ext4 does) but for now let's go with the conservative option where we stop immediately.

[PATCH openEuler-1.0-LTS] x86/msr-index: make SPEC_CTRL_IBRS assembler-portable

18 May '23

From: Nick Desaulniers <ndesaulniers(a)google.com> maillist inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6V709 CVE: NA Reference: https://lore.kernel.org/lkml/20221103210748.1343090-1-ndesaulniers@google.c… -------------------------------- GNU binutils' assembler (GAS) didn't support L suffixes on immediates until binutils 2.28 release. Building arch/x86/entry/entry_64.S with GAS v2.27 will produce the following assembler errors: arch/x86/entry/entry_64.S: Assembler messages: arch/x86/entry/entry_64.S:308: Error: found 'L', expected: ')' arch/x86/entry/entry_64.S:308: Error: found 'L', expected: ')' arch/x86/entry/entry_64.S:308: Error: junk `L<<(0)))' after expression arch/x86/entry/entry_64.S:596: Error: found 'L', expected: ')' arch/x86/entry/entry_64.S:596: Error: found 'L', expected: ')' arch/x86/entry/entry_64.S:596: Error: junk `L<<(0)))' after expression These come from the use of the preprocessor defined SPEC_CTRL_IBRS in the IBRS_ENTER and IBRS_EXIT assembler macros. SPEC_CTRL_IBRS was using the BIT macros from include/linux/bits.h which are only portable between C and assembler for assemblers such as GAS v2.28 (or newer) or clang because they use the L suffixes for immediate operands, which older GAS releases cannot parse. The kernel still supports GAS v2.23 and newer (and older for branches of stable). Let's expand the value of SPEC_CTRL_IBRS in place so that assemblers don't have issues parsing the value.

The ondisk AGF has a higher LSN than the recovered log item. xlog_recover_buf_commit_pass2 reads the buffer, compares the LSNs, and decides to skip replay because the ondisk buffer appears to be newer. Unfortunately, the ondisk buffer is corrupt, but recovery just read the buffer with no buffer ops specified: error = xfs_buf_read(mp->m_ddev_targp, buf_f->blf_blkno, buf_f->blf_len, buf_flags, &bp, NULL); Skipping the buffer leaves its contents in memory unverified. This sets us up for a kernel crash because xfs_refcount_recover_cow_leftovers reads the buffer (which is still around in XBF_DONE state, so no read verification) and creates a refcountbt cursor of height 32. This is impossible so we run off the end of the cursor object and crash. Fix this by invoking the verifier on all skipped buffers and aborting log recovery if the ondisk buffer is corrupt. It might be smarter to force replay the log item atop the buffer and then see if it'll pass the write verifier (like ext4 does) but for now let's go with the conservative option where we stop immediately.

[PATCH OLK-5.10] iommu/arm-smmu-v3: Fix ECMDQs is not initialized correctly
by Zhen Lei 18 May '23

18 May '23

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6WAZX -------------------------------- When the number of cores is greater than the number of ECMDQs, the number of ECMDQs occupied by each NUMA node is less than the number of cores of the node. Therefore, the first smmu->nr_ecmdq cores do not cover all ECMDQs.

[PATCH openEuler-22.03-LTS 01/14] uaccess: Add speculation barrier to copy_from_user()

From: Dave Hansen <dave.hansen(a)linux.intel.com> stable inclusion from stable-v5.10.170 commit 3b6ce54cfa2c04f0636fd0c985913af8703b408d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I71N8L CVE: CVE-2023-0459 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 74e19ef0ff8061ef55957c3abd71614ef0f42f47 upstream. The results of "access_ok()" can be mis-speculated. The result is that you can end speculatively: if (access_ok(from, size)) // Right here even for bad from/size combinations. On first glance, it would be ideal to just add a speculation barrier to "access_ok()" so that its results can never be mis-speculated. But there are lots of system calls just doing access_ok() via "copy_to_user()" and friends (example: fstat() and friends). Those are generally not problematic because they do not _consume_ data from userspace other than the pointer. They are also very quick and common system calls that should not be needlessly slowed down. "copy_from_user()" on the other hand uses a user-controller pointer and is frequently followed up with code that might affect caches. Take something like this: if (!copy_from_user(&kernelvar, uptr, size)) do_something_with(kernelvar); If userspace passes in an evil 'uptr' that *actually* points to a kernel addresses, and then do_something_with() has cache (or other) side-effects, it could allow userspace to infer kernel data values. Add a barrier to the common copy_from_user() code to prevent mis-speculated values which happen after the copy. Also add a stub for architectures that do not define barrier_nospec(). This makes the macro usable in generic code. Since the barrier is now usable in generic code, the x86 #ifdef in the BPF code can also go away.

Currently, only x86 architecture supports the CLOCKSOURCE_VALIDATE_LAST_CYCLE option. This option ensures that the timestamps returned by the clocksource are monotonically increasing, and helps avoid issues caused by hardware failures. This commit makes CLOCKSOURCE_VALIDATE_LAST_CYCLE configurable on the arm64 architecture, helps increase system stability and reliability.

[PATCH openEuler-1.0-LTS 1/2] netrom: Fix use-after-free caused by accept on already connected socket
by Yongqiang Liu 11 May '23

11 May '23

From: Hyunwoo Kim <v4bel(a)theori.io> stable inclusion from stable-v4.19.273 commit 2c1984d101978e979783bdb2376eb6eca9f8f627 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I70OFF CVE: CVE-2023-32269 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 611792920925fb088ddccbe2783c7f92fdfb6b64 ] If you call listen() and accept() on an already connect()ed AF_NETROM socket, accept() can successfully connect. This is because when the peer socket sends data to sendmsg, the skb with its own sk stored in the connected socket's sk->sk_receive_queue is connected, and nr_accept() dequeues the skb waiting in the sk->sk_receive_queue. As a result, nr_accept() allocates and returns a sock with the sk of the parent AF_NETROM socket. And here use-after-free can happen through complex race conditions: ``` cpu0 cpu1 1. socket_2 = socket(AF_NETROM) . . listen(socket_2) accepted_socket = accept(socket_2) 2. socket_1 = socket(AF_NETROM) nr_create() // sk refcount : 1 connect(socket_1) 3. write(accepted_socket) nr_sendmsg() nr_output() nr_kick() nr_send_iframe() nr_transmit_buffer() nr_route_frame() nr_loopback_queue() nr_loopback_timer() nr_rx_frame() nr_process_rx_frame(sk, skb); // sk : socket_1's sk nr_state3_machine() nr_queue_rx_frame() sock_queue_rcv_skb() sock_queue_rcv_skb_reason() __sock_queue_rcv_skb() __skb_queue_tail(list, skb); // list : socket_1's sk->sk_receive_queue 4. listen(socket_1) nr_listen() uaf_socket = accept(socket_1) nr_accept() skb_dequeue(&sk->sk_receive_queue); 5. close(accepted_socket) nr_release() nr_write_internal(sk, NR_DISCREQ) nr_transmit_buffer() // NR_DISCREQ nr_route_frame() nr_loopback_queue() nr_loopback_timer() nr_rx_frame() // sk : socket_1's sk nr_process_rx_frame() // NR_STATE_3 nr_state3_machine() // NR_DISCREQ nr_disconnect() nr_sk(sk)->state = NR_STATE_0; 6. close(socket_1) // sk refcount : 3 nr_release() // NR_STATE_0 sock_put(sk); // sk refcount : 0 sk_free(sk); close(uaf_socket) nr_release() sock_hold(sk); // UAF ``` KASAN report by syzbot: ``` BUG: KASAN: use-after-free in nr_release+0x66/0x460 net/netrom/af_netrom.c:520 Write of size 4 at addr ffff8880235d8080 by task syz-executor564/5128 Call Trace: <TASK> __dump_stack lib/dump_stack.c:88 [inline] dump_stack_lvl+0xd1/0x138 lib/dump_stack.c:106 print_address_description mm/kasan/report.c:306 [inline] print_report+0x15e/0x461 mm/kasan/report.c:417 kasan_report+0xbf/0x1f0 mm/kasan/report.c:517 check_region_inline mm/kasan/generic.c:183 [inline] kasan_check_range+0x141/0x190 mm/kasan/generic.c:189 instrument_atomic_read_write include/linux/instrumented.h:102 [inline] atomic_fetch_add_relaxed include/linux/atomic/atomic-instrumented.h:116 [inline] __refcount_add include/linux/refcount.h:193 [inline] __refcount_inc include/linux/refcount.h:250 [inline] refcount_inc include/linux/refcount.h:267 [inline] sock_hold include/net/sock.h:775 [inline] nr_release+0x66/0x460 net/netrom/af_netrom.c:520 __sock_release+0xcd/0x280 net/socket.c:650 sock_close+0x1c/0x20 net/socket.c:1365 __fput+0x27c/0xa90 fs/file_table.c:320 task_work_run+0x16f/0x270 kernel/task_work.c:179 exit_task_work include/linux/task_work.h:38 [inline] do_exit+0xaa8/0x2950 kernel/exit.c:867 do_group_exit+0xd4/0x2a0 kernel/exit.c:1012 get_signal+0x21c3/0x2450 kernel/signal.c:2859 arch_do_signal_or_restart+0x79/0x5c0 arch/x86/kernel/signal.c:306 exit_to_user_mode_loop kernel/entry/common.c:168 [inline] exit_to_user_mode_prepare+0x15f/0x250 kernel/entry/common.c:203 __syscall_exit_to_user_mode_work kernel/entry/common.c:285 [inline] syscall_exit_to_user_mode+0x1d/0x50 kernel/entry/common.c:296 do_syscall_64+0x46/0xb0 arch/x86/entry/common.c:86 entry_SYSCALL_64_after_hwframe+0x63/0xcd RIP: 0033:0x7f6c19e3c9b9 Code: Unable to access opcode bytes at 0x7f6c19e3c98f.

[PATCH openEuler-1.0-LTS] mm: memcontrol: switch to rcu protection in drain_all_stock()
by Yongqiang Liu 10 May '23

10 May '23

From: Roman Gushchin <guro(a)fb.com> mainline inclusion from mainline-v5.4-rc1 commit e1a366be5cb4f849ec4de170d50eebc08bb0af20 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I70T8Z CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Commit 72f0184c8a00 ("mm, memcg: remove hotplug locking from try_charge") introduced css_tryget()/css_put() calls in drain_all_stock(), which are supposed to protect the target memory cgroup from being released during the mem_cgroup_is_descendant() call. However, it's not completely safe. In theory, memcg can go away between reading stock->cached pointer and calling css_tryget(). This can happen if drain_all_stock() races with drain_local_stock() performed on the remote cpu as a result of a work, scheduled by the previous invocation of drain_all_stock(). The race is a bit theoretical and there are few chances to trigger it, but the current code looks a bit confusing, so it makes sense to fix it anyway. The code looks like as if css_tryget() and css_put() are used to protect stocks drainage. It's not necessary because stocked pages are holding references to the cached cgroup. And it obviously won't work for works, scheduled on other cpus. So, let's read the stock->cached pointer and evaluate the memory cgroup inside a rcu read section, and get rid of css_tryget()/css_put() calls.

10 May '23

From: Alan Stern <stern(a)rowland.harvard.edu> mainline inclusion from mainline-v6.2-rc5 commit d18dcfe9860e842f394e37ba01ca9440ab2178f4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I66IZK CVE: CVE-2022-4382 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------------------------------------------------------- The syzbot fuzzer and Gerald Lee have identified a use-after-free bug in the gadgetfs driver, involving processes concurrently mounting and unmounting the gadgetfs filesystem. In particular, gadgetfs_fill_super() can race with gadgetfs_kill_sb(), causing the latter to deallocate the_device while the former is using it.

[PATCH openEuler-1.0-LTS 01/12] dm thin: fix deadlock when swapping to thin device
by Yongqiang Liu 08 May '23

08 May '23

From: Coly Li <colyli(a)suse.de> stable inclusion from stable-v4.19.280 commit 84e13235e08941ce37aa9ee238b6dd007170f0fc category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I715PM CVE: NA -------------------------------- commit 9bbf5feecc7eab2c370496c1c161bbfe62084028 upstream. This is an already known issue that dm-thin volume cannot be used as swap, otherwise a deadlock may happen when dm-thin internal memory demand triggers swap I/O on the dm-thin volume itself. But thanks to commit a666e5c05e7c ("dm: fix deadlock when swapping to encrypted device"), the limit_swap_bios target flag can also be used for dm-thin to avoid the recursive I/O when it is used as swap. Fix is to simply set ti->limit_swap_bios to true in both pool_ctr() and thin_ctr(). In my test, I create a dm-thin volume /dev/vg/swap and use it as swap device. Then I run fio on another dm-thin volume /dev/vg/main and use large --blocksize to trigger swap I/O onto /dev/vg/swap. The following fio command line is used in my test, fio --name recursive-swap-io --lockmem 1 --iodepth 128 \ --ioengine libaio --filename /dev/vg/main --rw randrw \ --blocksize 1M --numjobs 32 --time_based --runtime=12h Without this fix, the whole system can be locked up within 15 seconds. With this fix, there is no any deadlock or hung task observed after 2 hours of running fio. Furthermore, if blocksize is changed from 1M to 128M, after around 30 seconds fio has no visible I/O, and the out-of-memory killer message shows up in kernel message. After around 20 minutes all fio processes are killed and the whole system is back to being alive. This is exactly what is expected when recursive I/O happens on dm-thin volume when it is used as swap.

[PATCH openEuler-1.0-LTS 1/7] scsi: dpt_i2o: Remove obsolete driver
by Yongqiang Liu 08 May '23

08 May '23

From: Arnd Bergmann <arnd(a)arndb.de> mainline inclusion from mainline-v6.0-rc1~14 commit b04e75a4a8a81887386a0d2dbf605a48e779d2a0 category: bugfix bugzilla: 188707, https://gitee.com/src-openeuler/kernel/issues/I6VK2F CVE: CVE-2023-2007 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------------------------- The dpt_i2o driver was fixed to stop using virt_to_bus() in 2008, but it still has a stale reference in an error handling code path that could never work. I submitted a patch to fix this reference earlier, but Hannes Reinecke suggested that removing the driver may be just as good here. The i2o driver layer was removed in 2015 with commit 4a72a7af462d ("staging: remove i2o subsystem"), but the even older dpt_i2o scsi driver stayed around. The last non-cleanup patches I could find were from Miquel van Smoorenburg and Mark Salyzyn back in 2008, they might know if there is any chance of the hardware still being used anywhere.

[PATCH openEuler-1.0-LTS 1/9] bonding: Fix memory leak when changing bond type to Ethernet
by Yongqiang Liu 08 May '23

08 May '23

From: Ido Schimmel <idosch(a)nvidia.com> mainline inclusion from mainline-v6.3-rc6 commit c484fcc058bada604d7e4e5228d4affb646ddbc2 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I718K0 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- When a net device is put administratively up, its 'IFF_UP' flag is set (if not set already) and a 'NETDEV_UP' notification is emitted, which causes the 8021q driver to add VLAN ID 0 on the device. The reverse happens when a net device is put administratively down. When changing the type of a bond to Ethernet, its 'IFF_UP' flag is incorrectly cleared, resulting in the kernel skipping the above process and VLAN ID 0 being leaked [1]. Fix by restoring the flag when changing the type to Ethernet, in a similar fashion to the restoration of the 'IFF_SLAVE' flag. The issue can be reproduced using the script in [2], with example out before and after the fix in [3].

[PATCH openEuler-1.0-LTS 1/3] bonding: restore IFF_MASTER/SLAVE flags on bond enslave ether type change
by Yongqiang Liu 06 May '23

06 May '23

From: Nikolay Aleksandrov <razor(a)blackwall.org> mainline inclusion from mainline-v6.3-rc3 commit 9ec7eb60dcbcb6c41076defbc5df7bbd95ceaba5 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6WNGK CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- Add bond_ether_setup helper which is used to fix ether_setup() calls in the bonding driver. It takes care of both IFF_MASTER and IFF_SLAVE flags, the former is always restored and the latter only if it was set. If the bond enslaves non-ARPHRD_ETHER device (changes its type), then releases it and enslaves ARPHRD_ETHER device (changes back) then we use ether_setup() to restore the bond device type but it also resets its flags and removes IFF_MASTER and IFF_SLAVE[1]. Use the bond_ether_setup helper to restore both after such transition.

[PATCH openEuler-1.0-LTS] ext4: only update i_reserved_data_blocks on successful block allocation
by Yongqiang Liu 05 May '23

05 May '23

From: Baokun Li <libaokun1(a)huawei.com> maillist inclusion category: bugfix bugzilla: 188499, https://gitee.com/openeuler/kernel/issues/I6TNVT CVE: NA Reference: https://patchwork.ozlabs.org/project/linux-ext4/patch/20230412124126.228671… ---------------------------------------- In our fault injection test, we create an ext4 file, migrate it to non-extent based file, then punch a hole and finally trigger a WARN_ON in the ext4_da_update_reserve_space(): EXT4-fs warning (device sda): ext4_da_update_reserve_space:369: ino 14, used 11 with only 10 reserved data blocks When writing back a non-extent based file, if we enable delalloc, the number of reserved blocks will be subtracted from the number of blocks mapped by ext4_ind_map_blocks(), and the extent status tree will be updated. We update the extent status tree by first removing the old extent_status and then inserting the new extent_status. If the block range we remove happens to be in an extent, then we need to allocate another extent_status with ext4_es_alloc_extent(). use old to remove to add new |----------|------------|------------| old extent_status The problem is that the allocation of a new extent_status failed due to a fault injection, and __es_shrink() did not get free memory, resulting in a return of -ENOMEM. Then do_writepages() retries after receiving -ENOMEM, we map to the same extent again, and the number of reserved blocks is again subtracted from the number of blocks in that extent. Since the blocks in the same extent are subtracted twice, we end up triggering WARN_ON at ext4_da_update_reserve_space() because used > ei->i_reserved_data_blocks. For non-extent based file, we update the number of reserved blocks after ext4_ind_map_blocks() is executed, which causes a problem that when we call ext4_ind_map_blocks() to create a block, it doesn't always create a block, but we always reduce the number of reserved blocks. So we move the logic for updating reserved blocks to ext4_ind_map_blocks() to ensure that the number of reserved blocks is updated only after we do succeed in allocating some new blocks.

[PATCH openEuler-1.0-LTS] mm: mem_reliable: Use zone_page_state to count free reliable pages
by Yongqiang Liu 28 Apr '23

28 Apr '23

However, this can be achieved by counting NR_FREE_PAGES for all non-movable zones, which will have better compatibility. Therefore, replace it.

If the allocation of new work fails, the on-stack fallback will be used and the reference count of the current wb is increased afterwards. If cgroup writeback membership switches occur before getting the reference count and the current wb is released as old_wd, then calling wb_get() or wb_put() will trigger the null pointer dereference above. This issue was introduced in v4.3-rc7 (see fix tag1). Both sync_inodes_sb() and __writeback_inodes_sb_nr() calls to bdi_split_work_to_wbs() can trigger this issue. For scenarios called via sync_inodes_sb(), originally commit 7fc5854f8c6e ("writeback: synchronize sync(2) against cgroup writeback membership switches") reduced the possibility of the issue by adding wb_switch_rwsem, but in v5.14-rc1 (see fix tag2) removed the "inode_io_list_del_locked(inode, old_wb)" from inode_switch_wbs_work_fn() so that wb->state contains WB_has_dirty_io, thus old_wb is not skipped when traversing wbs in bdi_split_work_to_wbs(), and the issue becomes easily reproducible again. To solve this problem, percpu_ref_exit() is called under RCU protection to avoid race between cgwb_release_workfn() and bdi_split_work_to_wbs(). Moreover, replace wb_get() with wb_tryget() in bdi_split_work_to_wbs(), and skip the current wb if wb_tryget() fails because the wb has already been shutdown.
