[PATCH openEuler-1.0-LTS 1/2] l2tp: Serialize access to sk_user_data with sk_callback_lock
by Yongqiang Liu 05 Dec '22

05 Dec '22

From: Jakub Sitnicki <jakub(a)cloudflare.com> mainline inclusion from mainline-v6.1-rc6 commit b68777d54fac21fc833ec26ea1a2a84f975ab035 category: bugfix bugzilla: 188056, https://gitee.com/src-openeuler/kernel/issues/I62RNU CVE: CVE-2022-4129 -------------------------------- sk->sk_user_data has multiple users, which are not compatible with each other. Writers must synchronize by grabbing the sk->sk_callback_lock. l2tp currently fails to grab the lock when modifying the underlying tunnel socket fields. Fix it by adding appropriate locking. We err on the side of safety and grab the sk_callback_lock also inside the sk_destruct callback overridden by l2tp, even though there should be no refs allowing access to the sock at the time when sk_destruct gets called. v4: - serialize write to sk_user_data in l2tp sk_destruct v3: - switch from sock lock to sk_callback_lock - document write-protection for sk_user_data v2: - update Fixes to point to origin of the bug - use real names in Reported/Tested-by tags Cc: Tom Parkin <tparkin(a)katalix.com> Fixes: 3557baabf280 ("[L2TP]: PPP over L2TP driver core") Reported-by: Haowei Yan <g1042620637(a)gmail.com> Signed-off-by: Jakub Sitnicki <jakub(a)cloudflare.com> Signed-off-by: David S.

[PATCH] memblock,arm64: expand the static memblock memory table
by Zhang Jian 01 Dec '22

01 Dec '22

From: Zhou Guanghui <zhouguanghui1(a)huawei.com> In a system(Huawei Ascend ARM64 SoC) using HBM, a multi-bit ECC error occurs, and the BIOS will mark the corresponding area (for example, 2 MB) as unusable. When the system restarts next time, these areas are not reported or reported as EFI_UNUSABLE_MEMORY. Both cases lead to an increase in the number of memblocks, whereas EFI_UNUSABLE_MEMORY leads to a larger number of memblocks. For example, if the EFI_UNUSABLE_MEMORY type is reported: ... memory[0x92] [0x0000200834a00000-0x0000200835bfffff], 0x0000000001200000 bytes on node 7 flags: 0x0 memory[0x93] [0x0000200835c00000-0x0000200835dfffff], 0x0000000000200000 bytes on node 7 flags: 0x4 memory[0x94] [0x0000200835e00000-0x00002008367fffff], 0x0000000000a00000 bytes on node 7 flags: 0x0 memory[0x95] [0x0000200836800000-0x00002008369fffff], 0x0000000000200000 bytes on node 7 flags: 0x4 memory[0x96] [0x0000200836a00000-0x0000200837bfffff], 0x0000000001200000 bytes on node 7 flags: 0x0 memory[0x97] [0x0000200837c00000-0x0000200837dfffff], 0x0000000000200000 bytes on node 7 flags: 0x4 memory[0x98] [0x0000200837e00000-0x000020087fffffff], 0x0000000048200000 bytes on node 7 flags: 0x0 memory[0x99] [0x0000200880000000-0x0000200bcfffffff], 0x0000000350000000 bytes on node 6 flags: 0x0 memory[0x9a] [0x0000200bd0000000-0x0000200bd01fffff], 0x0000000000200000 bytes on node 6 flags: 0x4 memory[0x9b] [0x0000200bd0200000-0x0000200bd07fffff], 0x0000000000600000 bytes on node 6 flags: 0x0 memory[0x9c] [0x0000200bd0800000-0x0000200bd09fffff], 0x0000000000200000 bytes on node 6 flags: 0x4 memory[0x9d] [0x0000200bd0a00000-0x0000200fcfffffff], 0x00000003ff600000 bytes on node 6 flags: 0x0 memory[0x9e] [0x0000200fd0000000-0x0000200fd01fffff], 0x0000000000200000 bytes on node 6 flags: 0x4 memory[0x9f] [0x0000200fd0200000-0x0000200fffffffff], 0x000000002fe00000 bytes on node 6 flags: 0x0 ... The EFI memory map is parsed to construct the memblock arrays before the memblock arrays can be resized. As the result, memory regions beyond INIT_MEMBLOCK_REGIONS are lost. Add a new macro INIT_MEMBLOCK_MEMORY_REGIONS to replace INIT_MEMBLOCK_REGTIONS to define the size of the static memblock.memory array. Allow overriding memblock.memory array size with architecture defined INIT_MEMBLOCK_MEMORY_REGIONS and make arm64 to set INIT_MEMBLOCK_MEMORY_REGIONS to 1024 when CONFIG_EFI is enabled.
