[PATCH openEuler-1.0-LTS v2] atl1c: Work around the DMA RX overflow issue
by Dong Chenchen 18 Jun '24

18 Jun '24

From: Sieng-Piaw Liew <liew.s.piaw(a)gmail.com> mainline inclusion from mainline-v6.7-rc1 commit 86565682e9053e5deb128193ea9e88531bbae9cf category: bugfix bugzilla: 190056, https://gitee.com/src-openeuler/kernel/issues/I9REDN CVE: CVE-2023-52834 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- This is based on alx driver commit 881d0327db37 ("net: alx: Work around the DMA RX overflow issue"). The alx and atl1c drivers had RX overflow error which was why a custom allocator was created to avoid certain addresses. The simpler workaround then created for alx driver, but not for atl1c due to lack of tester. Instead of using a custom allocator, check the allocated skb address and use skb_reserve() to move away from problematic 0x...fc0 address. Tested on AR8131 on Acer 4540.

[PATCH openEuler-22.03-LTS-SP1] mm: swap: fix race between free_swap_and_cache() and swapoff()
by Jinjiang Tu 18 Jun '24

18 Jun '24

From: Ryan Roberts <ryan.roberts(a)arm.com> stable inclusion from stable-v5.10.215 commit d85c11c97ecf92d47a4b29e3faca714dc1f18d0d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L4RJ CVE: CVE-2024-26960 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 82b1c07a0af603e3c47b906c8e991dc96f01688e ] There was previously a theoretical window where swapoff() could run and teardown a swap_info_struct while a call to free_swap_and_cache() was running in another thread. This could cause, amongst other bad possibilities, swap_page_trans_huge_swapped() (called by free_swap_and_cache()) to access the freed memory for swap_map. This is a theoretical problem and I haven't been able to provoke it from a test case. But there has been agreement based on code review that this is possible (see link below). Fix it by using get_swap_device()/put_swap_device(), which will stall swapoff(). There was an extra check in _swap_info_get() to confirm that the swap entry was not free.

[PATCH OLK-5.10] mm: swap: fix race between free_swap_and_cache() and swapoff()
by Jinjiang Tu 18 Jun '24

18 Jun '24

From: Ryan Roberts <ryan.roberts(a)arm.com> stable inclusion from stable-v5.10.215 commit d85c11c97ecf92d47a4b29e3faca714dc1f18d0d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L4RJ CVE: CVE-2024-26960 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 82b1c07a0af603e3c47b906c8e991dc96f01688e ] There was previously a theoretical window where swapoff() could run and teardown a swap_info_struct while a call to free_swap_and_cache() was running in another thread. This could cause, amongst other bad possibilities, swap_page_trans_huge_swapped() (called by free_swap_and_cache()) to access the freed memory for swap_map. This is a theoretical problem and I haven't been able to provoke it from a test case. But there has been agreement based on code review that this is possible (see link below). Fix it by using get_swap_device()/put_swap_device(), which will stall swapoff(). There was an extra check in _swap_info_get() to confirm that the swap entry was not free. This isn't present in get_swap_device() because it doesn't make sense in general due to the race between getting the reference and swapoff. So I've added an equivalent check directly in free_swap_and_cache(). Details of how to provoke one possible issue (thanks to David Hildenbrand for deriving this): --8<----- __swap_entry_free() might be the last user and result in "count == SWAP_HAS_CACHE". swapoff->try_to_unuse() will stop as soon as soon as si->inuse_pages==0.

From: Dan Carpenter <dan.carpenter(a)oracle.com> stable inclusion from stable-v4.19.219 commit bca19bb2dc2d89ce60c4a4a6e59609d4cf2e13ef category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9S27V CVE: CVE-2021-47571 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit b535917c51acc97fb0761b1edec85f1f3d02bda4 upstream.

[PATCH OLK-6.6] maple_tree: fix mas_empty_area_rev() null pointer dereference
by Zheng Yejian 17 Jun '24

17 Jun '24

From: "Liam R. Howlett" <Liam.Howlett(a)oracle.com> stable inclusion from stable-v6.6.31 commit 6c9c7c1e63b198a8b979ad963eb21410f10ccb00 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9TXID CVE: CVE-2024-36891 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 955a923d2809803980ff574270f81510112be9cf upstream. Currently the code calls mas_start() followed by mas_data_end() if the maple state is MA_START, but mas_start() may return with the maple state node == NULL. This will lead to a null pointer dereference when checking information in the NULL node, which is done in mas_data_end(). Avoid setting the offset if there is no node by waiting until after the maple state is checked for an empty or single entry state. A user could trigger the events to cause a kernel oops by unmapping all vmas to produce an empty maple tree, then mapping a vma that would cause the scenario described above.

[PATCH OLK-5.10] Bluetooth: L2CAP: Fix div-by-zero in l2cap_le_flowctl_init()
by Zhengchao Shao 17 Jun '24

17 Jun '24

From: Sungwoo Kim <iam(a)sung-woo.kim> mainline inclusion from mainline-v6.10-rc1 commit a5b862c6a221459d54e494e88965b48dcfa6cc44 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA3COJ CVE: CVE-2024-36968 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- l2cap_le_flowctl_init() can cause both div-by-zero and an integer overflow since hdev->le_mtu may not fall in the valid range. Move MTU from hci_dev to hci_conn to validate MTU and stop the connection process earlier if MTU is invalid. Also, add a missing validation in read_buffer_size() and make it return an error value if the validation fails. Now hci_conn_add() returns ERR_PTR() as it can fail due to the both a kzalloc failure and invalid MTU value. divide error: 0000 [#1] PREEMPT SMP KASAN NOPTI CPU: 0 PID: 67 Comm: kworker/u5:0 Tainted: G W 6.9.0-rc5+ #20 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 Workqueue: hci0 hci_rx_work RIP: 0010:l2cap_le_flowctl_init+0x19e/0x3f0 net/bluetooth/l2cap_core.c:547 Code: e8 17 17 0c 00 66 41 89 9f 84 00 00 00 bf 01 00 00 00 41 b8 02 00 00 00 4c 89 fe 4c 89 e2 89 d9 e8 27 17 0c 00 44 89 f0 31 d2 <66> f7 f3 89 c3 ff c3 4d 8d b7 88 00 00 00 4c 89 f0 48 c1 e8 03 42 RSP: 0018:ffff88810bc0f858 EFLAGS: 00010246 RAX: 00000000000002a0 RBX: 0000000000000000 RCX: dffffc0000000000 RDX: 0000000000000000 RSI: ffff88810bc0f7c0 RDI: ffffc90002dcb66f RBP: ffff88810bc0f880 R08: aa69db2dda70ff01 R09: 0000ffaaaaaaaaaa R10: 0084000000ffaaaa R11: 0000000000000000 R12: ffff88810d65a084 R13: dffffc0000000000 R14: 00000000000002a0 R15: ffff88810d65a000 FS: 0000000000000000(0000) GS:ffff88811ac00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000020000100 CR3: 0000000103268003 CR4: 0000000000770ef0 PKRU: 55555554 Call Trace: <TASK> l2cap_le_connect_req net/bluetooth/l2cap_core.c:4902 [inline] l2cap_le_sig_cmd net/bluetooth/l2cap_core.c:5420 [inline] l2cap_le_sig_channel net/bluetooth/l2cap_core.c:5486 [inline] l2cap_recv_frame+0xe59d/0x11710 net/bluetooth/l2cap_core.c:6809 l2cap_recv_acldata+0x544/0x10a0 net/bluetooth/l2cap_core.c:7506 hci_acldata_packet net/bluetooth/hci_core.c:3939 [inline] hci_rx_work+0x5e5/0xb20 net/bluetooth/hci_core.c:4176 process_one_work kernel/workqueue.c:3254 [inline] process_scheduled_works+0x90f/0x1530 kernel/workqueue.c:3335 worker_thread+0x926/0xe70 kernel/workqueue.c:3416 kthread+0x2e3/0x380 kernel/kthread.c:388 ret_from_fork+0x5c/0x90 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244 </TASK> Modules linked in: ---[ end trace 0000000000000000 ]--- Fixes: 6ed58ec520ad ("Bluetooth: Use LE buffers for LE traffic") Suggested-by: Luiz Augusto von Dentz <luiz.dentz(a)gmail.com> Signed-off-by: Sungwoo Kim <iam(a)sung-woo.kim> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz(a)intel.com> Conflicts: include/net/bluetooth/hci_core.h net/bluetooth/hci_conn.c net/bluetooth/hci_event.c net/bluetooth/l2cap_core.c net/bluetooth/sco.c net/bluetooth/iso.c [The conflict occurs because the commit eca0ae4aea66("Bluetooth: Add initial implementation of BIS connections") and 26afbd826ee3("Bluetooth: Add initial implementation of CIS connections") and 181a42edddf5(" Bluetooth: Make handle of hci_conn be unique") and c8992cffbe74(" Bluetooth: hci_event: Use of a function table to handle Command Complete") and e7b02296fb40 ("Bluetooth: Remove BT_HS") and ccf74f2390d6 ("Bluetooth: Add BTPROTO_ISO socket type") are not merged.

From: Sungwoo Kim <iam(a)sung-woo.kim> mainline inclusion from mainline-v6.10-rc1 commit a5b862c6a221459d54e494e88965b48dcfa6cc44 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA3COJ CVE: CVE-2024-36968 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- l2cap_le_flowctl_init() can cause both div-by-zero and an integer overflow since hdev->le_mtu may not fall in the valid range. Move MTU from hci_dev to hci_conn to validate MTU and stop the connection process earlier if MTU is invalid. Also, add a missing validation in read_buffer_size() and make it return an error value if the validation fails. Now hci_conn_add() returns ERR_PTR() as it can fail due to the both a kzalloc failure and invalid MTU value. divide error: 0000 [#1] PREEMPT SMP KASAN NOPTI CPU: 0 PID: 67 Comm: kworker/u5:0 Tainted: G W 6.9.0-rc5+ #20 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 Workqueue: hci0 hci_rx_work RIP: 0010:l2cap_le_flowctl_init+0x19e/0x3f0 net/bluetooth/l2cap_core.c:547 Code: e8 17 17 0c 00 66 41 89 9f 84 00 00 00 bf 01 00 00 00 41 b8 02 00 00 00 4c 89 fe 4c 89 e2 89 d9 e8 27 17 0c 00 44 89 f0 31 d2 <66> f7 f3 89 c3 ff c3 4d 8d b7 88 00 00 00 4c 89 f0 48 c1 e8 03 42 RSP: 0018:ffff88810bc0f858 EFLAGS: 00010246 RAX: 00000000000002a0 RBX: 0000000000000000 RCX: dffffc0000000000 RDX: 0000000000000000 RSI: ffff88810bc0f7c0 RDI: ffffc90002dcb66f RBP: ffff88810bc0f880 R08: aa69db2dda70ff01 R09: 0000ffaaaaaaaaaa R10: 0084000000ffaaaa R11: 0000000000000000 R12: ffff88810d65a084 R13: dffffc0000000000 R14: 00000000000002a0 R15: ffff88810d65a000 FS: 0000000000000000(0000) GS:ffff88811ac00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000020000100 CR3: 0000000103268003 CR4: 0000000000770ef0 PKRU: 55555554 Call Trace: <TASK> l2cap_le_connect_req net/bluetooth/l2cap_core.c:4902 [inline] l2cap_le_sig_cmd net/bluetooth/l2cap_core.c:5420 [inline] l2cap_le_sig_channel net/bluetooth/l2cap_core.c:5486 [inline] l2cap_recv_frame+0xe59d/0x11710 net/bluetooth/l2cap_core.c:6809 l2cap_recv_acldata+0x544/0x10a0 net/bluetooth/l2cap_core.c:7506 hci_acldata_packet net/bluetooth/hci_core.c:3939 [inline] hci_rx_work+0x5e5/0xb20 net/bluetooth/hci_core.c:4176 process_one_work kernel/workqueue.c:3254 [inline] process_scheduled_works+0x90f/0x1530 kernel/workqueue.c:3335 worker_thread+0x926/0xe70 kernel/workqueue.c:3416 kthread+0x2e3/0x380 kernel/kthread.c:388 ret_from_fork+0x5c/0x90 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244 </TASK> Modules linked in: ---[ end trace 0000000000000000 ]--- Fixes: 6ed58ec520ad ("Bluetooth: Use LE buffers for LE traffic") Suggested-by: Luiz Augusto von Dentz <luiz.dentz(a)gmail.com> Signed-off-by: Sungwoo Kim <iam(a)sung-woo.kim> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz(a)intel.com> Conflicts: include/net/bluetooth/hci_core.h net/bluetooth/hci_conn.c net/bluetooth/hci_event.c net/bluetooth/l2cap_core.c net/bluetooth/sco.c net/bluetooth/iso.c [The conflict occurs because the commit eca0ae4aea66("Bluetooth: Add initial implementation of BIS connections") and 26afbd826ee3("Bluetooth: Add initial implementation of CIS connections") and 181a42edddf5(" Bluetooth: Make handle of hci_conn be unique") and c8992cffbe74(" Bluetooth: hci_event: Use of a function table to handle Command Complete") and e7b02296fb40 ("Bluetooth: Remove BT_HS") and ccf74f2390d6 ("Bluetooth: Add BTPROTO_ISO socket type") are not merged.

From: Sungwoo Kim <iam(a)sung-woo.kim> mainline inclusion from mainline-v6.10-rc1 commit a5b862c6a221459d54e494e88965b48dcfa6cc44 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA3COJ CVE: CVE-2024-36968 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- l2cap_le_flowctl_init() can cause both div-by-zero and an integer overflow since hdev->le_mtu may not fall in the valid range. Move MTU from hci_dev to hci_conn to validate MTU and stop the connection process earlier if MTU is invalid. Also, add a missing validation in read_buffer_size() and make it return an error value if the validation fails. Now hci_conn_add() returns ERR_PTR() as it can fail due to the both a kzalloc failure and invalid MTU value. divide error: 0000 [#1] PREEMPT SMP KASAN NOPTI CPU: 0 PID: 67 Comm: kworker/u5:0 Tainted: G W 6.9.0-rc5+ #20 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 Workqueue: hci0 hci_rx_work RIP: 0010:l2cap_le_flowctl_init+0x19e/0x3f0 net/bluetooth/l2cap_core.c:547 Code: e8 17 17 0c 00 66 41 89 9f 84 00 00 00 bf 01 00 00 00 41 b8 02 00 00 00 4c 89 fe 4c 89 e2 89 d9 e8 27 17 0c 00 44 89 f0 31 d2 <66> f7 f3 89 c3 ff c3 4d 8d b7 88 00 00 00 4c 89 f0 48 c1 e8 03 42 RSP: 0018:ffff88810bc0f858 EFLAGS: 00010246 RAX: 00000000000002a0 RBX: 0000000000000000 RCX: dffffc0000000000 RDX: 0000000000000000 RSI: ffff88810bc0f7c0 RDI: ffffc90002dcb66f RBP: ffff88810bc0f880 R08: aa69db2dda70ff01 R09: 0000ffaaaaaaaaaa R10: 0084000000ffaaaa R11: 0000000000000000 R12: ffff88810d65a084 R13: dffffc0000000000 R14: 00000000000002a0 R15: ffff88810d65a000 FS: 0000000000000000(0000) GS:ffff88811ac00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000020000100 CR3: 0000000103268003 CR4: 0000000000770ef0 PKRU: 55555554 Call Trace: <TASK> l2cap_le_connect_req net/bluetooth/l2cap_core.c:4902 [inline] l2cap_le_sig_cmd net/bluetooth/l2cap_core.c:5420 [inline] l2cap_le_sig_channel net/bluetooth/l2cap_core.c:5486 [inline] l2cap_recv_frame+0xe59d/0x11710 net/bluetooth/l2cap_core.c:6809 l2cap_recv_acldata+0x544/0x10a0 net/bluetooth/l2cap_core.c:7506 hci_acldata_packet net/bluetooth/hci_core.c:3939 [inline] hci_rx_work+0x5e5/0xb20 net/bluetooth/hci_core.c:4176 process_one_work kernel/workqueue.c:3254 [inline] process_scheduled_works+0x90f/0x1530 kernel/workqueue.c:3335 worker_thread+0x926/0xe70 kernel/workqueue.c:3416 kthread+0x2e3/0x380 kernel/kthread.c:388 ret_from_fork+0x5c/0x90 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244 </TASK> Modules linked in: ---[ end trace 0000000000000000 ]--- Fixes: 6ed58ec520ad ("Bluetooth: Use LE buffers for LE traffic") Suggested-by: Luiz Augusto von Dentz <luiz.dentz(a)gmail.com> Signed-off-by: Sungwoo Kim <iam(a)sung-woo.kim> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz(a)intel.com> Conflicts: include/net/bluetooth/hci_core.h net/bluetooth/hci_conn.c net/bluetooth/hci_event.c net/bluetooth/l2cap_core.c net/bluetooth/sco.c [The conflict occurs because the commit eca0ae4aea66("Bluetooth: Add initial implementation of BIS connections") and 26afbd826ee3("Bluetooth: Add initial implementation of CIS connections") and 181a42edddf5(" Bluetooth: Make handle of hci_conn be unique") and c8992cffbe74(" Bluetooth: hci_event: Use of a function table to handle Command Complete") and e7b02296fb40 ("Bluetooth: Remove BT_HS") are not merged In the hci_conn_add function, if the MTU is abnormal, NULL is returned.

Now hci_conn_add() returns ERR_PTR() as it can fail due to the both a kzalloc failure and invalid MTU value. divide error: 0000 [#1] PREEMPT SMP KASAN NOPTI CPU: 0 PID: 67 Comm: kworker/u5:0 Tainted: G W 6.9.0-rc5+ #20 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 Workqueue: hci0 hci_rx_work RIP: 0010:l2cap_le_flowctl_init+0x19e/0x3f0 net/bluetooth/l2cap_core.c:547 Code: e8 17 17 0c 00 66 41 89 9f 84 00 00 00 bf 01 00 00 00 41 b8 02 00 00 00 4c 89 fe 4c 89 e2 89 d9 e8 27 17 0c 00 44 89 f0 31 d2 <66> f7 f3 89 c3 ff c3 4d 8d b7 88 00 00 00 4c 89 f0 48 c1 e8 03 42 RSP: 0018:ffff88810bc0f858 EFLAGS: 00010246 RAX: 00000000000002a0 RBX: 0000000000000000 RCX: dffffc0000000000 RDX: 0000000000000000 RSI: ffff88810bc0f7c0 RDI: ffffc90002dcb66f RBP: ffff88810bc0f880 R08: aa69db2dda70ff01 R09: 0000ffaaaaaaaaaa R10: 0084000000ffaaaa R11: 0000000000000000 R12: ffff88810d65a084 R13: dffffc0000000000 R14: 00000000000002a0 R15: ffff88810d65a000 FS: 0000000000000000(0000) GS:ffff88811ac00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000020000100 CR3: 0000000103268003 CR4: 0000000000770ef0 PKRU: 55555554 Call Trace: <TASK> l2cap_le_connect_req net/bluetooth/l2cap_core.c:4902 [inline] l2cap_le_sig_cmd net/bluetooth/l2cap_core.c:5420 [inline] l2cap_le_sig_channel net/bluetooth/l2cap_core.c:5486 [inline] l2cap_recv_frame+0xe59d/0x11710 net/bluetooth/l2cap_core.c:6809 l2cap_recv_acldata+0x544/0x10a0 net/bluetooth/l2cap_core.c:7506 hci_acldata_packet net/bluetooth/hci_core.c:3939 [inline] hci_rx_work+0x5e5/0xb20 net/bluetooth/hci_core.c:4176 process_one_work kernel/workqueue.c:3254 [inline] process_scheduled_works+0x90f/0x1530 kernel/workqueue.c:3335 worker_thread+0x926/0xe70 kernel/workqueue.c:3416 kthread+0x2e3/0x380 kernel/kthread.c:388 ret_from_fork+0x5c/0x90 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244 </TASK> Modules linked in: ---[ end trace 0000000000000000 ]--- Fixes: 6ed58ec520ad ("Bluetooth: Use LE buffers for LE traffic") Suggested-by: Luiz Augusto von Dentz <luiz.dentz(a)gmail.com> Signed-off-by: Sungwoo Kim <iam(a)sung-woo.kim> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz(a)intel.com> Conflicts: include/net/bluetooth/hci_core.h net/bluetooth/hci_conn.c net/bluetooth/hci_event.c net/bluetooth/l2cap_core.c net/bluetooth/sco.c [The conflict occurs because the commit eca0ae4aea66("Bluetooth: Add initial implementation of BIS connections") and 26afbd826ee3("Bluetooth: Add initial implementation of CIS connections") and 181a42edddf5(" Bluetooth: Make handle of hci_conn be unique") and c8992cffbe74(" Bluetooth: hci_event: Use of a function table to handle Command Complete") and e7b02296fb40 ("Bluetooth: Remove BT_HS") are not merged In the hci_conn_add function, if the MTU is abnormal, NULL is returned.

[PATCH openEuler-1.0-LTS v2] dhugetlb: use rcu lock to protect hpool
by Liu Shixin 17 Jun '24

17 Jun '24

hulk inclusion category: bugfix bugzilla: 46904, https://gitee.com/openeuler/kernel/issues/IA5JXN -------------------------------- In freeing process, set memcg->hpool or dpool_global_hpool to NULL and then freeing it. To avoid UAF problem of hpool, we have to make sure the users that already hold pointer to hpool don't use the pointer after freeing hpool. The freeing of hpool should block until make sure all such users don't use hpool. Since anyone who want to use hpool have to increase its refcount at first. Use rcu_read_lock() and synchronize_rcu() to guarantee all such users failed to get hpool before freeing hpool.

[PATCH openEuler-1.0-LTS] dhugetlb: use rcu lock to protect hpool
by Liu Shixin 14 Jun '24

14 Jun '24

hulk inclusion category: bugfix bugzilla: 46904, https://gitee.com/openeuler/kernel/issues/IA5JXN -------------------------------- In freeing process, set memcg->hpool or dpool_global_hpool to NULL and then freeing it. To avoid UAF problem of hpool, we have to make sure the users that already hold pointer to hpool don't use the pointer after freeing hpool. The freeing of hpool should block until make sure all such users don't use hpool. Since anyone who want to use hpool have to increase its refcount at first. Use rcu_read_lock() and synchronize_rcu() to guarantee all such users failed to get hpool before freeing hpool.

[PATCH openEuler-1.0-LTS] RDMA/cma: Ensure rdma_addr_cancel() happens before issuing more requests
by Zheng Zucheng 14 Jun '24

From: Jason Gunthorpe <jgg(a)nvidia.com> mainline inclusion from mainline-v5.15-rc4 commit 305d568b72f17f674155a2a8275f865f207b3808 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4OB CVE: CVE-2021-47391 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- The FSM can run in a circle allowing rdma_resolve_ip() to be called twice on the same id_priv. While this cannot happen without going through the work, it violates the invariant that the same address resolution background request cannot be active twice. CPU 1 CPU 2 rdma_resolve_addr(): RDMA_CM_IDLE -> RDMA_CM_ADDR_QUERY rdma_resolve_ip(addr_handler) #1 process_one_req(): for #1 addr_handler(): RDMA_CM_ADDR_QUERY -> RDMA_CM_ADDR_BOUND mutex_unlock(&id_priv->handler_mutex); [.. handler still running ..] rdma_resolve_addr(): RDMA_CM_ADDR_BOUND -> RDMA_CM_ADDR_QUERY rdma_resolve_ip(addr_handler) !! two requests are now on the req_list rdma_destroy_id(): destroy_id_handler_unlock(): _destroy_id(): cma_cancel_operation(): rdma_addr_cancel() // process_one_req() self removes it spin_lock_bh(&lock); cancel_delayed_work(&req->work); if (!list_empty(&req->list)) == true ! rdma_addr_cancel() returns after process_on_req #1 is done kfree(id_priv) process_one_req(): for #2 addr_handler(): mutex_lock(&id_priv->handler_mutex); !! Use after free on id_priv rdma_addr_cancel() expects there to be one req on the list and only cancels the first one. The self-removal behavior of the work only happens after the handler has returned. This yields a situations where the req_list can have two reqs for the same "handle" but rdma_addr_cancel() only cancels the first one. The second req remains active beyond rdma_destroy_id() and will use-after-free id_priv once it inevitably triggers. Fix this by remembering if the id_priv has called rdma_resolve_ip() and always cancel before calling it again. This ensures the req_list never gets more than one item in it and doesn't cost anything in the normal flow that never uses this strange error path.
