CVE: NA
--------------------------------
Commit 505a666ee3fc ("writeback: plug writeback in wb_writeback() and
writeback_inodes_wb()") has us holding a plug during wb_writeback, which
may cause a potential ABBA dead lock:
wb_writeback fat_file_fsync
blk_start_plug(&plug)
for (;;) {
iter i-1: some reqs have been added into plug->mq_list // LOCK A
iter i:
progress = __writeback_inodes_wb(wb, work)
. writeback_sb_inodes // fat's bdev
. __writeback_single_inode
. . generic_writepages
. . __block_write_full_page
. . . . __generic_file_fsync
. . . . sync_inode_metadata

. . . trylock_buffer(bh) // LOCK B
. . . redirty_page_for_writepage
. . . wbc->pages_skipped++

. wrote += write_chunk - wbc.nr_to_write // wrote > 0
. requeue_inode

if (progress) // progress > 0
continue;
iter i+1:
queue_io
// similar process with iter i, infinite for-loop !
}
blk_finish_plug(&plug) // flush plug won't be called
Above process triggers a hungtask like:

In my test, 'need_resched()' (which is imported by 590dca3a71 "fs-writeback:
unplug before cond_resched in writeback_sb_inodes") in function
'writeback_sb_inodes()' seldom comes true, unless cond_resched() is deleted
from write_cache_pages().
Fix it by correcting wrote number according number of skipped pages
in writeback_sb_inodes().

+=========================================
+Processor MMIO Stale Data Vulnerabilities
+=========================================
+
+Processor MMIO Stale Data Vulnerabilities are a class of memory-mapped I/O
+(MMIO) vulnerabilities that can expose data. The sequences of operations for
+exposing data range from simple to very complex. Because most of the
+vulnerabilities require the attacker to have access to MMIO, many environments
+are not affected. System environments using virtualization where MMIO access is
+provided to untrusted guests may need mitigation. These vulnerabilities are
+not transient execution attacks. However, these vulnerabilities may propagate
+stale data into core fill buffers where the data can subsequently be inferred
+by an unmitigated transient execution attack. Mitigation for these
+vulnerabilities includes a combination of microcode update and software
+changes, depending on the platform and usage model. Some of these mitigations
+are similar to those used to mitigate Microarchitectural Data Sampling (MDS) or
+those used to mitigate Special Register Buffer Data Sampling (SRBDS).
+
+Data Propagators
+================
+Propagators are operations that result in stale data being copied or moved from
+one microarchitectural buffer or register to another. Processor MMIO Stale Data
+Vulnerabilities are operations that may result in stale data being directly
+read into an architectural, software-visible state or sampled from a buffer or
+register.
+
+Fill Buffer Stale Data Propagator (FBSDP)
+-----------------------------------------
+Stale data may propagate from fill buffers (FB) into the non-coherent portion
+of the uncore on some non-coherent writes. Fill buffer propagation by itself
+does not make stale data architecturally visible. Stale data must be propagated
+to a location where it is subject to reading or sampling.
+
+Sideband Stale Data Propagator (SSDP)
+-------------------------------------
+The sideband stale data propagator (SSDP) is limited to the client (including
+Intel Xeon server E3) uncore implementation. The sideband response buffer is
+shared by all client cores. For non-coherent reads that go to sideband
+destinations, the uncore logic returns 64 bytes of data to the core, including
+both requested data and unrequested stale data, from a transaction buffer and
+the sideband response buffer. As a result, stale data from the sideband
+response and transaction buffers may now reside in a core fill buffer.
+
+Primary Stale Data Propagator (PSDP)
+------------------------------------
+The primary stale data propagator (PSDP) is limited to the client (including
+Intel Xeon server E3) uncore implementation. Similar to the sideband response
+buffer, the primary response buffer is shared by all client cores. For some
+processors, MMIO primary reads will return 64 bytes of data to the core fill
+buffer including both requested data and unrequested stale data. This is
+similar to the sideband stale data propagator.
+
+Vulnerabilities
+===============
+Device Register Partial Write (DRPW) (CVE-2022-21166)
+-----------------------------------------------------
+Some endpoint MMIO registers incorrectly handle writes that are smaller than
+the register size. Instead of aborting the write or only copying the correct
+subset of bytes (for example, 2 bytes for a 2-byte write), more bytes than
+specified by the write transaction may be written to the register. On
+processors affected by FBSDP, this may expose stale data from the fill buffers
+of the core that created the write transaction.
+
+Shared Buffers Data Sampling (SBDS) (CVE-2022-21125)
+----------------------------------------------------
+After propagators may have moved data around the uncore and copied stale data
+into client core fill buffers, processors affected by MFBDS can leak data from
+the fill buffer. It is limited to the client (including Intel Xeon server E3)
+uncore implementation.
+
+Shared Buffers Data Read (SBDR) (CVE-2022-21123)
+------------------------------------------------
+It is similar to Shared Buffer Data Sampling (SBDS) except that the data is
+directly read into the architectural software-visible state. It is limited to
+the client (including Intel Xeon server E3) uncore implementation.
+
+Affected Processors
+===================
+Not all the CPUs are affected by all the variants. For instance, most
+processors for the server market (excluding Intel Xeon E3 processors) are
+impacted by only Device Register Partial Write (DRPW).
+
+Below is the list of affected Intel processors [#f1]_:
+
+ =================== ============ =========
+ Common name Family_Model Steppings
+ =================== ============ =========
+ HASWELL_X 06_3FH 2,4

+ ROCKETLAKE 06_A7H 1
+ =================== ============ =========
+
+If a CPU is in the affected processor list, but not affected by a variant, it
+is indicated by new bits in MSR IA32_ARCH_CAPABILITIES. As described in a later
+section, mitigation largely remains the same for all the variants, i.e. to
+clear the CPU fill buffers via VERW instruction.
+
+New bits in MSRs
+================
+Newer processors and microcode update on existing affected processors added new
+bits to IA32_ARCH_CAPABILITIES MSR. These bits can be used to enumerate
+specific variants of Processor MMIO Stale Data vulnerabilities and mitigation
+capability.
+
+MSR IA32_ARCH_CAPABILITIES
+--------------------------
+Bit 13 - SBDR_SSDP_NO - When set, processor is not affected by either the
+ Shared Buffers Data Read (SBDR) vulnerability or the sideband stale
+ data propagator (SSDP).
+Bit 14 - FBSDP_NO - When set, processor is not affected by the Fill Buffer
+ Stale Data Propagator (FBSDP).
+Bit 15 - PSDP_NO - When set, processor is not affected by Primary Stale Data
+ Propagator (PSDP).
+Bit 17 - FB_CLEAR - When set, VERW instruction will overwrite CPU fill buffer
+ values as part of MD_CLEAR operations. Processors that do not
+ enumerate MDS_NO (meaning they are affected by MDS) but that do
+ enumerate support for both L1D_FLUSH and MD_CLEAR implicitly enumerate
+ FB_CLEAR as part of their MD_CLEAR support.
+Bit 18 - FB_CLEAR_CTRL - Processor supports read and write to MSR
+ IA32_MCU_OPT_CTRL[FB_CLEAR_DIS]. On such processors, the FB_CLEAR_DIS
+ bit can be set to cause the VERW instruction to not perform the
+ FB_CLEAR action. Not all processors that support FB_CLEAR will support
+ FB_CLEAR_CTRL.
+
+MSR IA32_MCU_OPT_CTRL
+---------------------
+Bit 3 - FB_CLEAR_DIS - When set, VERW instruction does not perform the FB_CLEAR
+action. This may be useful to reduce the performance impact of FB_CLEAR in
+cases where system software deems it warranted (for example, when performance
+is more critical, or the untrusted software has no MMIO access). Note that
+FB_CLEAR_DIS has no impact on enumeration (for example, it does not change
+FB_CLEAR or MD_CLEAR enumeration) and it may not be supported on all processors
+that enumerate FB_CLEAR.
+
+Mitigation
+==========
+Like MDS, all variants of Processor MMIO Stale Data vulnerabilities have the
+same mitigation strategy to force the CPU to clear the affected buffers before
+an attacker can extract the secrets.
+
+This is achieved by using the otherwise unused and obsolete VERW instruction in
+combination with a microcode update. The microcode clears the affected CPU
+buffers when the VERW instruction is executed.
+
+Kernel reuses the MDS function to invoke the buffer clearing:
+
+ mds_clear_cpu_buffers()
+
+On MDS affected CPUs, the kernel already invokes CPU buffer clear on
+kernel/userspace, hypervisor/guest and C-state (idle) transitions. No
+additional mitigation is needed on such CPUs.
+
+For CPUs not affected by MDS or TAA, mitigation is needed only for the attacker
+with MMIO capability. Therefore, VERW is not required for kernel/userspace. For
+virtualization case, VERW is only needed at VMENTER for a guest with MMIO
+capability.
+
+Mitigation points
+-----------------
+Return to user space
+^^^^^^^^^^^^^^^^^^^^
+Same mitigation as MDS when affected by MDS/TAA, otherwise no mitigation
+needed.
+
+C-State transition
+^^^^^^^^^^^^^^^^^^
+Control register writes by CPU during C-state transition can propagate data
+from fill buffer to uncore buffers. Execute VERW before C-state transition to
+clear CPU fill buffers.
+
+Guest entry point
+^^^^^^^^^^^^^^^^^
+Same mitigation as MDS when processor is also affected by MDS/TAA, otherwise
+execute VERW at VMENTER only for MMIO capable guests. On CPUs not affected by
+MDS/TAA, guest without MMIO access cannot extract secrets using Processor MMIO
+Stale Data vulnerabilities, so there is no need to execute VERW for such guests.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+The kernel command line allows to control the Processor MMIO Stale Data
+mitigations at boot time with the option "mmio_stale_data=". The valid
+arguments for this option are:
+
+ ========== =================================================================
+ full If the CPU is vulnerable, enable mitigation; CPU buffer clearing
+ on exit to userspace and when entering a VM. Idle transitions are
+ protected as well. It does not automatically disable SMT.
+ full,nosmt Same as full, with SMT disabled on vulnerable CPUs. This is the
+ complete mitigation.
+ off Disables mitigation completely.
+ ========== =================================================================
+
+If the CPU is affected and mmio_stale_data=off is not supplied on the kernel
+command line, then the kernel selects the appropriate mitigation.
+
+Mitigation status information
+-----------------------------
+The Linux kernel provides a sysfs interface to enumerate the current
+vulnerability status of the system: whether the system is vulnerable, and
+which mitigations are active. The relevant sysfs file is:
+
+ /sys/devices/system/cpu/vulnerabilities/mmio_stale_data
+
+The possible values in this file are:
+
+ .. list-table::
+
+ * - 'Not affected'
+ - The processor is not vulnerable
+ * - 'Vulnerable'
+ - The processor is vulnerable, but no mitigation enabled
+ * - 'Vulnerable: Clear CPU buffers attempted, no microcode'
+ - The processor is vulnerable, but microcode is not updated. The
+ mitigation is enabled on a best effort basis.
+ * - 'Mitigation: Clear CPU buffers'
+ - The processor is vulnerable and the CPU buffer clearing mitigation is
+ enabled.
+
+If the processor is vulnerable then the following information is appended to
+the above information:
+
+ ======================== ===========================================
+ 'SMT vulnerable' SMT is enabled
+ 'SMT disabled' SMT is disabled
+ 'SMT Host state unknown' Kernel runs in a VM, Host SMT state unknown
+ ======================== ===========================================

bugzilla: https://gitee.com/openeuler/kernel/issues/I5CO9A
CVE: NA
---------------------------------
As pass through devices, hypervisor can`t control the status of
device, and can`t track dirty memory DMA from device, during
migration.
The goal of this framework is to combine hardware to accomplish
the task above.

From: Gou Hao <gouhao(a)uniontech.com>
Patch series "Add extended attributes support for EulerFS".
I refer to the extended attribute implementation code of ext2 file
system. At first, I implemented it completely according to the extended
attribute of ext file system. But later, I changed the disk layout of
entries.
About layout of entry:
The layout of ext2's extended attribute is that name and value
are stored separately,with name growing from top to bottom and value
growing from bottom to top. I think the layout of ext2 wastes
space, because, Name and value are aligned with 4 bytes, In the worst
case, the name and value of entry need 3 bytes of padding respectively,
and a total of 6 bytes are wasted.
I store the name and value together. In the worst case, only need
3 bytes of padding.Use xattr-test.c selftests, with the same block
size, my method can store 112 entries, while using ext2 layout can
only store 102 entries.
In ext4 file system, value can be stored in different blocks, which
increases the scalability. In my method, it can add a pointer to the
next block in the header to achieve the same function, and it is simpler.
The performance of my method is the same as that of ext2, or even better.
About block share:
In ext2, if the extended attributes of two files are exactly
the same, they can share the same disk block. Its implementation
process is:
1. When accessing the extended attribute of a file, add this
extended attribute block to a specific cache.
2. When setting the extended attribute of a file, if there is
a block with exactly the same content as this extended attribute
in the cache, share that block directly.
There is a problem here. If the block of a file is not added to the
cache, the extended attribute block will not be shared.So in this
patch set, I didn't realize the shared disk block. I'll implement it
later when there is a good method or when there is a need.
At present, only user. prefix xattr is implemented. Trusted, ACL and
security will be implemented later.
Gou Hao (7):
eulerfs: add EULER_FS_XATTR config
eulerfs: add related fields of extended attributes
eulerfs: add alloc xattr block interface
eulerfs: implement extended attribute core functions
eulerfs: add callback interface of extended attribute
eulerfs: add implementation of user. prefix extended attribute
eulerfs: add selftests for eulerfs extended attribute

我运行咱们的系统在一台分腾d2000的机器上，发现网卡是驱动不起来的。
网卡型号是PHYT0004，走的MDIO的总线，使用stmmac的驱动。
以上是我了解的相关技术，目前网卡驱动不起来，所以没有相关dmesg日志。
正在着手解决该问题，所以提请咨询。

[PATCH openEuler-1.0-LTS 1/4] ext4: add EXT4_INODE_HAS_XATTR_SPACE macro in xattr.h
by Yongqiang Liu 02 Jul '22

From: Baokun Li <libaokun1(a)huawei.com>
hulk inclusion
category: bugfix
bugzilla: 186866, https://gitee.com/openeuler/kernel/issues/I5DTBL
CVE: NA
--------------------------------
When adding an xattr to an inode, we must ensure that the inode_size is
not less than EXT4_GOOD_OLD_INODE_SIZE + extra_isize + pad. Otherwise,
the end position may be greater than the start position, resulting in UAF.
