[PATCH OLK-5.10] net: ena: Fix incorrect descriptor free behavior
by Zhao Mengmeng 28 May '24

28 May '24

From: David Arinzon <darinzon(a)amazon.com> stable inclusion from stable-v5.10.216 commit b26aa765f7437e1bbe8db4c1641b12bd5dd378f0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QRO8 CVE: CVE-2024-35958 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit bf02d9fe00632d22fa91d34749c7aacf397b6cde ] ENA has two types of TX queues: - queues which only process TX packets arriving from the network stack - queues which only process TX packets forwarded to it by XDP_REDIRECT or XDP_TX instructions The ena_free_tx_bufs() cycles through all descriptors in a TX queue and unmaps + frees every descriptor that hasn't been acknowledged yet by the device (uncompleted TX transactions). The function assumes that the processed TX queue is necessarily from the first category listed above and ends up using napi_consume_skb() for descriptors belonging to an XDP specific queue. This patch solves a bug in which, in case of a VF reset, the descriptors aren't freed correctly, leading to crashes.

This has the abort handler get a ref to the conn so it won't be freed from under it. Note: this is not needed for device/target reset because we are holding the eh_mutex when accessing the conn.

[PATCH OLK-5.10] wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes
by Liu Jian 27 May '24

27 May '24

From: Felix Fietkau <nbd(a)nbd.name> stable inclusion from stable-v5.10.215 commit e8b067c4058c0121ac8ca71559df8e2e08ff1a7e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q8YT CVE: CVE-2024-35789 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------- commit 4f2bdb3c5e3189297e156b3ff84b140423d64685 upstream. When moving a station out of a VLAN and deleting the VLAN afterwards, the fast_rx entry still holds a pointer to the VLAN's netdev, which can cause use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx after the VLAN change.

From: Johan Hovold <johan(a)kernel.org> stable inclusion from stable-v4.19.217 commit 7a2021b896de1ad559d33b5c5cdd20b982242088 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RD17 CVE: CVE-2021-47475 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a23461c47482fc232ffc9b819539d1f837adf2b1 upstream. The driver uses endpoint-sized USB transfer buffers but up until recently had no sanity checks on the sizes. Commit e1f13c879a7c ("staging: comedi: check validity of wMaxPacketSize of usb endpoints found") inadvertently fixed NULL-pointer dereferences when accessing the transfer buffers in case a malicious device has a zero wMaxPacketSize. Make sure to allocate buffers large enough to handle also the other accesses that are done without a size check (e.g. byte 18 in vmk80xx_cnt_insn_read() for the VMK8061_MODEL) to avoid writing beyond the buffers, for example, when doing descriptor fuzzing. The original driver was for a low-speed device with 8-byte buffers. Support was later added for a device that uses bulk transfers and is presumably a full-speed device with a maximum 64-byte wMaxPacketSize.

From: WangJinchao <wangjinchao(a)xfusion.com> stable inclusion from stable-v5.10.201 commit 41aad9d6953984d134fc50f631f24ef476875d4d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RQM3 CVE: CVE-2023-52854 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 7ddc21e317b360c3444de3023bcc83b85fabae2f ] In a high-load arm64 environment, the pcrypt_aead01 test in LTP can lead to system UAF (Use-After-Free) issues. Due to the lengthy analysis of the pcrypt_aead01 function call, I'll describe the problem scenario using a simplified model: Suppose there's a user of padata named `user_function` that adheres to the padata requirement of calling `padata_free_shell` after `serial()` has been invoked, as demonstrated in the following code: ```c struct request { struct padata_priv padata; struct completion *done; }; void parallel(struct padata_priv *padata) { do_something(); } void serial(struct padata_priv *padata) { struct request *request = container_of(padata, struct request, padata); complete(request->done); } void user_function() { DECLARE_COMPLETION(done) padata->parallel = parallel; padata->serial = serial; padata_do_parallel(); wait_for_completion(&done); padata_free_shell(); } ``` In the corresponding padata.c file, there's the following code: ```c static void padata_serial_worker(struct work_struct *serial_work) { ... cnt = 0; while (!list_empty(&local_list)) { ... padata->serial(padata); cnt++; } local_bh_enable(); if (refcount_sub_and_test(cnt, &pd->refcnt)) padata_free_pd(pd); } ``` Because of the high system load and the accumulation of unexecuted softirq at this moment, `local_bh_enable()` in padata takes longer to execute than usual. Subsequently, when accessing `pd->refcnt`, `pd` has already been released by `padata_free_shell()`, resulting in a UAF issue with `pd->refcnt`. The fix is straightforward: add `refcount_dec_and_test` before calling `padata_free_pd` in `padata_free_shell`.

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> stable inclusion from stable-v5.10.216 commit 41586487769eede64ab1aa6c65c74cbf76c12ef0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QRRC CVE: CVE-2024-35950 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 3eadd887dbac1df8f25f701e5d404d1b90fd0fea upstream. The modes[] array contains pointers to modes on the connectors' mode lists, which are protected by dev->mode_config.mutex. Thus we need to extend modes[] the same protection or by the time we use it the elements may already be pointing to freed/reused memory.

[PATCH openEuler-1.0-LTS v2] net/tls: Fix flipped sign in tls_err_abort() calls
by Ziyang Xuan 25 May '24

25 May '24

From: Daniel Jordan <daniel.m.jordan(a)oracle.com> mainline inclusion from mainline-v5.15 commit da353fac65fede6b8b4cfe207f0d9408e3121105 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RCYN CVE: CVE-2021-47496 -------------------------------- sk->sk_err appears to expect a positive value, a convention that ktls doesn't always follow and that leads to memory corruption in other code. For instance, [kworker] tls_encrypt_done(..., err=<negative error from crypto request>) tls_err_abort(.., err) sk->sk_err = err; [task] splice_from_pipe_feed ... tls_sw_do_sendpage if (sk->sk_err) { ret = -sk->sk_err; // ret is positive splice_from_pipe_feed (continued) ret = actor(...) // ret is still positive and interpreted as bytes // written, resulting in underflow of buf->len and // sd->len, leading to huge buf->offset and bogus // addresses computed in later calls to actor() Fix all tls_err_abort() callers to pass a negative error code consistently and centralize the error-prone sign flip there, throwing in a warning to catch future misuse and uninlining the function so it really does only warn once.

However, this is not necessary, because I2C core already has its own locking for that. More importantly, this flag can cause a lock-up: if the flag is set in i2c_hid_xfer() and an interrupt happens, the interrupt handler (i2c_hid_irq) will check this flag and return immediately without doing anything, then the interrupt handler will be invoked again in an infinite loop. Since interrupt handler is an RT task, it takes over the CPU and the flag-clearing task never gets scheduled, thus we have a lock-up. Delete this unnecessary flag.

[PATCH openEuler-1.0-LTS] net/tls: Fix flipped sign in tls_err_abort() calls
by Ziyang Xuan 25 May '24

25 May '24

From: Daniel Jordan <daniel.m.jordan(a)oracle.com> mainline inclusion from mainline-v5.15 commit da353fac65fede6b8b4cfe207f0d9408e3121105 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RCYN CVE: CVE-2021-47496 -------------------------------- sk->sk_err appears to expect a positive value, a convention that ktls doesn't always follow and that leads to memory corruption in other code. For instance, [kworker] tls_encrypt_done(..., err=<negative error from crypto request>) tls_err_abort(.., err) sk->sk_err = err; [task] splice_from_pipe_feed ... tls_sw_do_sendpage if (sk->sk_err) { ret = -sk->sk_err; // ret is positive splice_from_pipe_feed (continued) ret = actor(...) // ret is still positive and interpreted as bytes // written, resulting in underflow of buf->len and // sd->len, leading to huge buf->offset and bogus // addresses computed in later calls to actor() Fix all tls_err_abort() callers to pass a negative error code consistently and centralize the error-prone sign flip there, throwing in a warning to catch future misuse and uninlining the function so it really does only warn once.

[PATCH openEuler-1.0-LTS] drm/radeon: fix a possible null pointer dereference
by Liu Chuang 25 May '24

25 May '24

[PATCH openEuler-1.0-LTS] nvmem: Fix shift-out-of-bound (UBSAN) with byte size cells
by Cai Xinchen 25 May '24

25 May '24

From: Stephen Boyd <swboyd(a)chromium.org> stable inclusion from stable-v4.19.213 commit eb0fc8e7170e61eaf65d28dee4a8baf4e86b19ca category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RD7J CVE: CVE-2021-47497 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 5d388fa01fa6eb310ac023a363a6cb216d9d8fe9 upstream. If a cell has 'nbits' equal to a multiple of BITS_PER_BYTE the logic *p &= GENMASK((cell->nbits%BITS_PER_BYTE) - 1, 0); will become undefined behavior because nbits modulo BITS_PER_BYTE is 0, and we subtract one from that making a large number that is then shifted more than the number of bits that fit into an unsigned long. UBSAN reports this problem: UBSAN: shift-out-of-bounds in drivers/nvmem/core.c:1386:8 shift exponent 64 is too large for 64-bit type 'unsigned long' CPU: 6 PID: 7 Comm: kworker/u16:0 Not tainted 5.15.0-rc3+ #9 Hardware name: Google Lazor (rev3+) with KB Backlight (DT) Workqueue: events_unbound deferred_probe_work_func Call trace: dump_backtrace+0x0/0x170 show_stack+0x24/0x30 dump_stack_lvl+0x64/0x7c dump_stack+0x18/0x38 ubsan_epilogue+0x10/0x54 __ubsan_handle_shift_out_of_bounds+0x180/0x194 __nvmem_cell_read+0x1ec/0x21c nvmem_cell_read+0x58/0x94 nvmem_cell_read_variable_common+0x4c/0xb0 nvmem_cell_read_variable_le_u32+0x40/0x100 a6xx_gpu_init+0x170/0x2f4 adreno_bind+0x174/0x284 component_bind_all+0xf0/0x264 msm_drm_bind+0x1d8/0x7a0 try_to_bring_up_master+0x164/0x1ac __component_add+0xbc/0x13c component_add+0x20/0x2c dp_display_probe+0x340/0x384 platform_probe+0xc0/0x100 really_probe+0x110/0x304 __driver_probe_device+0xb8/0x120 driver_probe_device+0x4c/0xfc __device_attach_driver+0xb0/0x128 bus_for_each_drv+0x90/0xdc __device_attach+0xc8/0x174 device_initial_probe+0x20/0x2c bus_probe_device+0x40/0xa4 deferred_probe_work_func+0x7c/0xb8 process_one_work+0x128/0x21c process_scheduled_works+0x40/0x54 worker_thread+0x1ec/0x2a8 kthread+0x138/0x158 ret_from_fork+0x10/0x20 Fix it by making sure there are any bits to mask out.

[PATCH openEuler-1.0-LTS] ipv6: Fix infinite recursion in fib6_dump_done().
by Zhengchao Shao 25 May '24

25 May '24

From: Kuniyuki Iwashima <kuniyu(a)amazon.com> stable inclusion from stable-v4.19.312 commit 9472d07cd095cbd3294ac54c42f304a38fbe9bfe category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QG76 CVE: CVE-2024-35886 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit d21d40605bca7bd5fc23ef03d4c1ca1f48bc2cae upstream. syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1] From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0] 12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8) Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done(). fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page. To avoid the issue, let's set the destructor after kzalloc().

[PATCH OLK-5.10] net: atlantic: eliminate double free in error handling logic

25 May '24

From: Igor Russkikh <irusskikh(a)marvell.com> mainline inclusion from mainline-v6.8-rc1 commit b3cb7a830a24527877b0bc900b9bd74a96aea928 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q919 CVE: CVE-2023-52664 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Driver has a logic leak in ring data allocation/free, where aq_ring_free could be called multiple times on same ring, if system is under stress and got memory allocation error. Ring pointer was used as an indicator of failure, but this is not correct since only ring data is allocated/deallocated. Ring itself is an array member. Changing ring allocation functions to return error code directly. This simplifies error handling and eliminates aq_ring_free on higher layer.

[PATCH OLK-5.10] ipv6: Fix infinite recursion in fib6_dump_done().
by Zhengchao Shao 25 May '24

25 May '24

From: Kuniyuki Iwashima <kuniyu(a)amazon.com> stable inclusion from stable-v5.10.215 commit fd307f2d91d40fa7bc55df3e2cd1253fabf8a2d6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QG76 CVE: CVE-2024-35886 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit d21d40605bca7bd5fc23ef03d4c1ca1f48bc2cae upstream. syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1] From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0] 12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8) Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done(). fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page. To avoid the issue, let's set the destructor after kzalloc().

[PATCH OLK-5.10] drm/amdgpu: handle the case of pci_channel_io_frozen only in amdgpu_pci_resume
by Xiongfeng Wang 24 May '24

24 May '24

From: Guchun Chen <guchun.chen(a)amd.com> mainline inclusion from mainline-v5.15-rc5 commit 248b061689a40f4fed05252ee2c89f87cf26d7d8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4NB CVE: CVE-2021-47421 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In current code, when a PCI error state pci_channel_io_normal is detectd, it will report PCI_ERS_RESULT_CAN_RECOVER status to PCI driver, and PCI driver will continue the execution of PCI resume callback report_resume by pci_walk_bridge, and the callback will go into amdgpu_pci_resume finally, where write lock is releasd unconditionally without acquiring such lock first. In this case, a deadlock will happen when other threads start to acquire the read lock. To fix this, add a member in amdgpu_device strucutre to cache pci_channel_state, and only continue the execution in amdgpu_pci_resume when it's pci_channel_io_frozen.

[PATCH openEuler-1.0-LTS] hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced from sysfs
by Zheng Yejian 24 May '24

24 May '24

From: Vadim Pasternak <vadimp(a)nvidia.com> stable inclusion from stable-v4.19.209 commit 5c6e0bce647d9cb32a17d58ffa669b3421fcc6ca category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4O0 CVE: CVE-2021-47393 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit e6fab7af6ba1bc77c78713a83876f60ca7a4a064 ] Fan speed minimum can be enforced from sysfs. For example, setting current fan speed to 20 is used to enforce fan speed to be at 100% speed, 19 - to be not below 90% speed, etcetera. This feature provides ability to limit fan speed according to some system wise considerations, like absence of some replaceable units or high system ambient temperature. Request for changing fan minimum speed is configuration request and can be set only through 'sysfs' write procedure. In this situation value of argument 'state' is above nominal fan speed maximum. Return non-zero code in this case to avoid thermal_cooling_device_stats_update() call, because in this case statistics update violates thermal statistics table range. The issues is observed in case kernel is configured with option CONFIG_THERMAL_STATISTICS. Here is the trace from KASAN: [ 159.506659] BUG: KASAN: slab-out-of-bounds in thermal_cooling_device_stats_update+0x7d/0xb0 [ 159.516016] Read of size 4 at addr ffff888116163840 by task hw-management.s/7444 [ 159.545625] Call Trace: [ 159.548366] dump_stack+0x92/0xc1 [ 159.552084] ? thermal_cooling_device_stats_update+0x7d/0xb0 [ 159.635869] thermal_zone_device_update+0x345/0x780 [ 159.688711] thermal_zone_device_set_mode+0x7d/0xc0 [ 159.694174] mlxsw_thermal_modules_init+0x48f/0x590 [mlxsw_core] [ 159.700972] ? mlxsw_thermal_set_cur_state+0x5a0/0x5a0 [mlxsw_core] [ 159.731827] mlxsw_thermal_init+0x763/0x880 [mlxsw_core] [ 160.070233] RIP: 0033:0x7fd995909970 [ 160.074239] Code: 73 01 c3 48 8b 0d 28 d5 2b 00 f7 d8 64 89 01 48 83 c8 ff c3 66 0f 1f 44 00 00 83 3d 99 2d 2c 00 00 75 10 b8 01 00 00 00 0f 05 <48> 3d 01 f0 ff ..

[PATCH openEuler-1.0-LTS] ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr
by Zhao Mengmeng 24 May '24

24 May '24

From: Jiri Benc <jbenc(a)redhat.com> stable inclusion from stable-v4.19.313 commit b4b3b69a19016d4e7fbdbd1dbcc184915eb862e1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QRPL CVE: CVE-2024-35969 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 7633c4da919ad51164acbf1aa322cc1a3ead6129 ] Although ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it still means hlist_for_each_entry_rcu can return an item that got removed from the list. The memory itself of such item is not freed thanks to RCU but nothing guarantees the actual content of the memory is sane. In particular, the reference count can be zero. This can happen if ipv6_del_addr is called in parallel. ipv6_del_addr removes the entry from inet6_addr_lst (hlist_del_init_rcu(&ifp->addr_lst)) and drops all references (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough timing, this can happen: 1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry. 2. Then, the whole ipv6_del_addr is executed for the given entry. The reference count drops to zero and kfree_rcu is scheduled. 3. ipv6_get_ifaddr continues and tries to increments the reference count (in6_ifa_hold). 4.

[PATCH OLK-5.10] ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr
by Zhao Mengmeng 23 May '24

23 May '24

From: Jiri Benc <jbenc(a)redhat.com> stable inclusion from stable-v5.10.216 commit 3fb02ec57ead2891a2306af8c51a306bc5945e70 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QRPL CVE: CVE-2024-35969 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 7633c4da919ad51164acbf1aa322cc1a3ead6129 ] Although ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it still means hlist_for_each_entry_rcu can return an item that got removed from the list. The memory itself of such item is not freed thanks to RCU but nothing guarantees the actual content of the memory is sane. In particular, the reference count can be zero. This can happen if ipv6_del_addr is called in parallel. ipv6_del_addr removes the entry from inet6_addr_lst (hlist_del_init_rcu(&ifp->addr_lst)) and drops all references (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough timing, this can happen: 1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry. 2. Then, the whole ipv6_del_addr is executed for the given entry. The reference count drops to zero and kfree_rcu is scheduled. 3. ipv6_get_ifaddr continues and tries to increments the reference count (in6_ifa_hold). 4. The rcu is unlocked and the entry is freed. 5. The freed entry is returned. Prevent increasing of the reference count in such case. The name in6_ifa_hold_safe is chosen to mimic the existing fib6_info_hold_safe. [ 41.506330] refcount_t: addition on 0; use-after-free.

[PATCH OLK-6.6] Bluetooth: L2CAP: Fix slab-use-after-free in l2cap_connect()

Also make the l2cap_connect() return type void. Nothing is using the returned value but it is ugly to return a potentially freed pointer.

[PATCH OLK-5.10] drm/i915/gt: Reset queue_priority_hint on parking

From: Chris Wilson <chris(a)chris-wilson.co.uk> stable inclusion from stable-v5.10.216 commit fe34587acc995e7b1d7a5d3444a0736721ec32b3 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L5FX CVE: CVE-2024-26937 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit 4a3859ea5240365d21f6053ee219bb240d520895 upstream. Originally, with strict in order execution, we could complete execution only when the queue was empty. Preempt-to-busy allows replacement of an active request that may complete before the preemption is processed by HW. If that happens, the request is retired from the queue, but the queue_priority_hint remains set, preventing direct submission until after the next CS interrupt is processed.

[PATCH OLK-6.6 v2] mm: add thp anon pmd size mapping align control
by Ze Zuo 23 May '24

23 May '24

From: Kefeng Wang <wangkefeng.wang(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I9R7N8 CVE: NA ------------------------------------------------- After committing df0ad0579ac9 ('mm: align larger anonymous mappings on THP boundaries'), we found a number of issues, eg, a significant increase in memory access latency on arm64, which was addressed by commit bb713c2a4a43 (arm64: mmap: disable align larger anonymous mappings on THP boundaries), but subsequently found on x86 that the patch also resulted in a significant degradation of the SPECCPU test. Commit 449846913eb6('mm: huge_memory: add thp mapping align control') has implemented the sysfs interface control of 64 KB aligned mapping in arm64, based on this for thp_align_mapping to add a new bit to control pmd size page alignment, where the 64K alignment mapping enable for arm64 will depend on the new bits being turned on. it is disabled by default, and could be enabled by /sys/kernel/mm/transparent_hugepage/thp_mapping_align.

by Zhang Qiao 23 May '24

23 May '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9RMHW CVE: NA -------------------------------- When perform load balance, a NUMA imbalance is allowed if busy CPUs is less than the maximum threshold, it keeps a pair of communication tasks on the current node when the destination is lightly loaded. 1. But, calculate_imbalance() use local->sum_nr_running, it may not be accurate, because communication tasks is on busiest group, so should be busiest->sum_nr_running. 2. At the same time, idles cpus are used to calculate imbalance, but the group_weight may not be the same between local and busiest groups. In this case, even if both groups are very idle, imbalance will be calculated very large, so the imbalance is calculated by calculating the difference of busy cpus between groups.
