[PATCH OLK-6.6 00/26] arm64: Support for running as guest in Arm CCA
by Cai Xinchen 20 Jun '25

20 Jun '25

This series adds support for running Linux in a protected VM under the Arm Confidential Compute Architecture (CCA). To support CCA guest, we do things as follow: 1. Revert some virtcca patches to reduce conflicts 2. Backport pkvm guest series patches to support memory encrypt api. 3. Backport virt coco to support tsm report 4. Backport CCA guest patches 5. Backport jump label patches to fix data abort when adding modules 6. Add log to notify rodata=full 7. Recover virtcca Cai Xinchen (2): Revert "virtcca feature : disable swiotlb for passthrough device" Revert "gicv3: add lpi support for cvm guest" Dan Williams (3): virt: coco: Add a coco/Makefile and coco/Kconfig configfs-tsm: Introduce a shared ABI for attestation reports mm/slab: Add __free() support for kvfree Helge Deller (1): parisc: Delay write-protection until mark_rodata_ro() call Peter Zijlstra (1): jump_label,module: Don't alloc static_key_mod for __ro_after_init keys Sami Mujawar (1): virt: arm-cca-guest: TSM_REPORT support for realms Steven Price (7): arm64: realm: Query IPA size from the RMM arm64: Enforce bounce buffers for realm DMA arm64: mm: Avoid TLBI when marking pages as valid arm64: Document Arm Confidential Compute irqchip/gic-v3-its: Share ITS tables with a non-trusted hypervisor irqchip/gic-v3-its: Fix over allocation in itt_alloc_pool() irqchip/gic-v3-its: Rely on genpool alignment Suzuki K Poulose (7): arm64: rsi: Add RSI definitions arm64: Detect if in a realm and set RIPAS RAM arm64: rsi: Add support for checking whether an MMIO is protected arm64: rsi: Map unprotected MMIO as decrypted efi: arm64: Map Device with Prot Shared arm64: Enable memory encrypt for Realms arm64: realm: ioremap: Allow mapping memory as encrypted Will Deacon (2): arm64: mm: Add top-level dispatcher for internal mem_encrypt API arm64: mm: Add confidential computing hook to ioremap_prot() Yiwei Zhuang (1): rme: make sure realm guest map memory in page granularity yxk (1): gicv3: add lpi support for virtcca cvm guest Documentation/ABI/testing/configfs-tsm | 82 ++++ Documentation/arch/arm64/arm-cca.rst | 69 +++ Documentation/arch/arm64/booting.rst | 3 + Documentation/arch/arm64/index.rst | 1 + MAINTAINERS | 8 + arch/arm64/Kconfig | 4 + arch/arm64/include/asm/io.h | 12 + arch/arm64/include/asm/mem_encrypt.h | 24 + arch/arm64/include/asm/pgtable-prot.h | 4 + arch/arm64/include/asm/pgtable.h | 5 + arch/arm64/include/asm/rsi.h | 68 +++ arch/arm64/include/asm/rsi_cmds.h | 160 +++++++ arch/arm64/include/asm/rsi_smc.h | 193 ++++++++ arch/arm64/include/asm/set_memory.h | 4 + arch/arm64/include/asm/virtcca_cvm_guest.h | 8 + arch/arm64/kernel/Makefile | 2 +- arch/arm64/kernel/efi.c | 12 +- arch/arm64/kernel/rsi.c | 165 +++++++ arch/arm64/kernel/setup.c | 3 + arch/arm64/kernel/virtcca_cvm_guest.c | 24 + arch/arm64/mm/Makefile | 2 +- arch/arm64/mm/init.c | 10 +- arch/arm64/mm/ioremap.c | 23 +- arch/arm64/mm/mem_encrypt.c | 50 +++ arch/arm64/mm/pageattr.c | 98 +++- arch/parisc/mm/init.c | 16 +- drivers/irqchip/irq-gic-v3-its.c | 329 +++++--------- drivers/virt/Kconfig | 8 +- drivers/virt/Makefile | 5 +- drivers/virt/coco/Kconfig | 18 + drivers/virt/coco/Makefile | 10 + drivers/virt/coco/arm-cca-guest/Kconfig | 11 + drivers/virt/coco/arm-cca-guest/Makefile | 2 + .../virt/coco/arm-cca-guest/arm-cca-guest.c | 224 +++++++++ drivers/virt/coco/tsm.c | 425 ++++++++++++++++++ include/asm-generic/sections.h | 5 + include/linux/jump_label.h | 3 + include/linux/slab.h | 2 + include/linux/tsm.h | 69 +++ include/linux/virtcca_cvm_domain.h | 10 + init/main.c | 1 + kernel/jump_label.c | 53 +++ 42 files changed, 1990 insertions(+), 235 deletions(-) create mode 100644 Documentation/ABI/testing/configfs-tsm create mode 100644 Documentation/arch/arm64/arm-cca.rst create mode 100644 arch/arm64/include/asm/mem_encrypt.h create mode 100644 arch/arm64/include/asm/rsi.h create mode 100644 arch/arm64/include/asm/rsi_cmds.h create mode 100644 arch/arm64/include/asm/rsi_smc.h create mode 100644 arch/arm64/kernel/rsi.c create mode 100644 arch/arm64/mm/mem_encrypt.c create mode 100644 drivers/virt/coco/Kconfig create mode 100644 drivers/virt/coco/Makefile create mode 100644 drivers/virt/coco/arm-cca-guest/Kconfig create mode 100644 drivers/virt/coco/arm-cca-guest/Makefile create mode 100644 drivers/virt/coco/arm-cca-guest/arm-cca-guest.c create mode 100644 drivers/virt/coco/tsm.c create mode 100644 include/linux/tsm.h -- 2.18.0.huawei.25

[PATCH OLK-5.10] cifs: fix mount deadlock by avoiding super block iteration in DFS reconnect
by Wang Zhaolong 19 Jun '25

19 Jun '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICE4PV -------------------------------- A deadlock issue occurs when network interruption during mount triggers DFS reconnection logic that calls iterate_supers_type(). The detailed call process is as follows: mount.cifs cifsd path_mount do_new_mount vfs_get_tree legacy_get_tree cifs_smb3_do_mount sget alloc_super down_write_nested(&s->s_umount, ..); // hold lock cifs_read_super cifs_root_iget cifs_get_inode_info smb2_query_path_info smb2_compound_op compound_send_recv wait_for_response // wait for cifsd to wake it up cifs_demultiplex_thread cifs_read_from_socket cifs_readv_from_socket server_unresponsive cifs_reconnect cifs_get_tcp_super __cifs_get_super iterate_supers_type down_read(&sb->s_umount); // block mid->callback() cifs_wake_up_task wake_up_process // won't be executed do_new_mount_fc up_write(&sb->s_umount); // release lock here This patch fixes the problem by doing the following: - Add vfs_sb back-pointer to cifs_sb_info for direct access - Protect list traversal with existing tcon->sb_list_lock - Use atomic operations to safely manage super block references - Remove complex callback-based iteration in favor of simple loop Fixes: 93d5cb517db3 ("cifs: Add support for failover in cifs_reconnect()") Signed-off-by: Wang Zhaolong <wangzhaolong1(a)huawei.com> --- fs/cifs/cifs_fs_sb.h | 1 + fs/cifs/cifsfs.c | 1 + fs/cifs/connect.c | 10 ++-- fs/cifs/misc.c | 125 ++++++++++++++++++++++--------------------- 4 files changed, 71 insertions(+), 66 deletions(-) diff --git a/fs/cifs/cifs_fs_sb.h b/fs/cifs/cifs_fs_sb.h index d14002d67b6a..d180ef3f9d89 100644 --- a/fs/cifs/cifs_fs_sb.h +++ b/fs/cifs/cifs_fs_sb.h @@ -58,10 +58,11 @@ struct cifs_sb_info { struct rb_root tlink_tree;

[PATCH] drm: phytium: fix NULL dereference issue in drm_gem_object_free

From: Li Chen <chenl311(a)chinatelecom.cn> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICGG2A ---------------------------------------------------------------------- Syzkaller crashed kernel in drm path. The root cause is that phytium_drm_gem_object_funcs is not assigned before phytium_gem_create_object enters the failed_dma_alloc label. Let's fix this issue by assigning the function earlier. Below is the crash log: ``` [ 9042.703078] [drm:phytium_gem_create_object [phytium_dc_drm]] *ERROR* fail to allocate vram buffer with size 3de4000 [ 9042.717862] Unable to handle kernel NULL pointer
