ext2: improve consistency of ext2_fsblk_t datatype usage
The ext2 block allocation/deallocation functions and their respective calls use a mixture of unsigned long and ext2_fsblk_t datatypes to index the desired ext2 block. This commit replaces occurrences of unsigned long with ext2_fsblk_t, covering the functions ext2_new_block(), ext2_new_blocks(), ext2_free_blocks(), ext2_free_data() and ext2_free_branches(). This commit is rather conservative, and only replaces unsigned long with ext2_fsblk_t if the variable is used to index a specific ext2 block.

ext2: dump current reservation window info
There's report BUG in 'ext2_try_to_allocate_with_rsv()', although there's now dump of all reservation windows information. But there's unknown which window is being processed.So this is not helpful for locating the issue. To better analyze the problem, dump the information about reservation window that is being processed. And just bail with error instead of BUG here.

However, there is no protection between ext2_xattr_set() and do_writepages() so these two functions can conflict on handling the reservation window. To solve about issue don't use the reservation window when allocating block for xattr.

ext2: fix datatype of block number in ext2_xattr_set2()
I run a small server that uses external hard drives for backups. The backup software I use uses ext2 filesystems with 4KiB block size and the server is running SELinux and therefore relies on xattr. I recently upgraded the hard drives from 4TB to 12TB models. I noticed that after transferring some TBs I got a filesystem error "Freeing blocks not in datazone - block = 18446744071529317386, count = 1" and the backup process stopped. Trying to fix the fs with e2fsck resulted in a completely corrupted fs. The error probably came from ext2_free_blocks(), and because of the large number 18e19 this problem immediately looked like some kind of integer overflow. Whereas the 4TB fs was about 1e9 blocks, the new 12TB is about 3e9 blocks. So, searching the ext2 code, I came across the line in fs/ext2/xattr.c:745 where ext2_new_block() is called and the resulting block number is stored in the variable block as an int datatype. If a block with a block number greater than INT32_MAX is returned, this variable overflows and the call to sb_getblk() at line fs/ext2/xattr.c:750 fails, then the call to ext2_free_blocks() produces the error.

udf: Fix -Wstringop-overflow warnings
Use unsigned type in call to macro mint_t(). This avoids confusing the
compiler about possible negative values that would cause the value in
_len_ to wrap around.

architecture with allyesconfig (GCC 13):

quota: simplify drop_dquot_ref()
As Honza said, remove_inode_dquot_ref() currently does not release the last dquot reference but instead adds the dquot to tofree_head list. This is because dqput() can sleep while dropping of the last dquot reference (writing back the dquot and calling ->release_dquot()) and that must not happen under dq_list_lock. Now that dqput() queues the final dquot cleanup into a workqueue, remove_inode_dquot_ref() can call dqput() unconditionally and we can significantly simplify it. Here we open code the simplified code of remove_inode_dquot_ref() into remove_dquot_ref() and remove the function put_dquot_list() which is no longer used.

quota: fix dqput() to follow the guarantees dquot_srcu should provide
The dquot_mark_dquot_dirty() using dquot references from the inode
should be protected by dquot_srcu. quota_off code takes care to call
synchronize_srcu(&dquot_srcu) to not drop dquot references while they
are used by other users. But dquot_transfer() breaks this assumption.
We call dquot_transfer() to drop the last reference of dquot and add
it to free_dquots, but there may still be other users using the dquot
at this time, as shown in the function graph below:
cpu1 cpu2
_________________|_________________
wb_do_writeback CHOWN(1)
...
ext4_da_update_reserve_space
dquot_claim_block
...
dquot_mark_dquot_dirty // try to dirty old quota
test_bit(DQ_ACTIVE_B, &dquot->dq_flags) // still ACTIVE
if (test_bit(DQ_MOD_B, &dquot->dq_flags))
// test no dirty, wait dq_list_lock
...
dquot_transfer
__dquot_transfer
dqput_all(transfer_from) // rls old dquot
dqput // last dqput
dquot_release
clear_bit(DQ_ACTIVE_B, &dquot->dq_flags)
atomic_dec(&dquot->dq_count)
put_dquot_last(dquot)
list_add_tail(&dquot->dq_free, &free_dquots)
// add the dquot to free_dquots
if (!test_and_set_bit(DQ_MOD_B, &dquot->dq_flags))
add dqi_dirty_list // add released dquot to dirty_list
This can cause various issues, such as dquot being destroyed by
dqcache_shrink_scan() after being added to free_dquots, which can trigger
a UAF in dquot_mark_dquot_dirty(); or after dquot is added to free_dquots
and then to dirty_list, it is added to free_dquots again after
dquot_writeback_dquots() is executed, which causes the free_dquots list to
be corrupted and triggers a UAF when dqcache_shrink_scan() is called for
freeing dquot twice.
As Honza said, we need to fix dquot_transfer() to follow the guarantees
dquot_srcu should provide. But calling synchronize_srcu() directly from
dquot_transfer() is too expensive (and mostly unnecessary). So we add
dquot whose last reference should be dropped to the new global dquot
list releasing_dquots, and then queue work item which would call
synchronize_srcu() and after that perform the final cleanup of all the
dquots on releasing_dquots.

quota: rename dquot_active() to inode_quota_active()
Now we have a helper function dquot_dirty() to determine if dquot has DQ_MOD_B bit. dquot_active() can easily be misunderstood as a helper function to determine if dquot has DQ_ACTIVE_B bit.

Let init_file() and its callers take care of cleaning up each after
their own allocated resources on error.

NFS client updates for Linux 6.5
Highlights include:
Stable fixes and other bugfixes:
- nfs: don't report STATX_BTIME in ->getattr
- Revert "NFSv4: Retry LOCK on OLD_STATEID during delegation return"
since it breaks NFSv4 state recovery.
- NFSv4.1: freeze the session table upon receiving NFS4ERR_BADSESSION
- Fix the NFSv4.2 xattr cache shrinker_id
- Force a ctime update after a NFSv4.2 SETXATTR call
Features and cleanups:
- NFS and RPC over TLS client code from Chuck Lever.
- Support for use of abstract unix socket addresses with the rpcbind
daemon.
- Sysfs API to allow shutdown of the kernel RPC client and prevent
umount() hangs if the server is known to be permanently down.
- XDR cleanups from Anna.

A single regression fix for x86:
Moving the invocation of arch_cpu_finalize_init() earlier in the boot process caused a boot regression on IBT enabled system. The root cause is not the move of arch_cpu_finalize_init() itself. The system fails to boot because the subsequent efi_enter_virtual_mode() code has a non-IBT safe EFI call inside. This was never noticed because IBT was enabled after the EFI initialization. Switching the EFI call to use the IBT safe wrapper cures the problem. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmSga0ITHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYofPAEADCjJ40zgv7cbi6VTKudQhASwclWimy zJk1hR6u+Gt7slDAOS/lcHwPzwPB2wn9VsdTHClSHeJbdT3GBKMCOQOFaj1mHvOW e9H7PKUn76OLUSQtpquNiXvnkZGGK/FkTBCi1dEX3xhrWYQ9EVAg/9gDPLtCR5vv cS95KAETGq/7Krxdkgn/w1cav13t+WA25EjAochwG0DAiqVpj+QK1X+dvm8S9F4I MAyLboPK7cN7WijMVxruy1ho+n8L4ZHv6GcOnd9hD/Z6Tyk48hTvQOpVD7V3h1Yc GWzXVyOETuDAwBubfbxCFWQ2nbzwE6uCTGlwyaCmCxixxNSXhyiysvLOLgZr+tD9 97/Z2tZM+nWjnL8vXvpVCKTNJHTssgh2GvUiKzecRuJWK/FoyfbiZllztVPewmRx k9hwf1qMzW8/XpcpfuY9XkfOBIPDUqWpKBtl9XpprU3EFOjEFfkNmdhGPFHkKefG v0LL3dc19f5N8/tFJN5mEww1ZolgQ0aIKqvT0CeY0x0MvCTT214OWb59tzrn+dw3 tth+pGIZnh+5qM8geE1jQ162zkg+r0UaK4TClTqgwzrxIUHmBygI+LVnuPu2iYMi KlJSaOiU60NjzzVVujbSFclPIgkcINuVuQh5zyTGMBLtRgxPzARKTr8v9dqalHeH xcmDJsrKIpMy7A== =T/8G -----END PGP SIGNATURE----- Merge tag 'x86-urgent-2023-07-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fix from Thomas Gleixner: "A single regression fix for x86: Moving the invocation of arch_cpu_finalize_init() earlier in the boot process caused a boot regression on IBT enabled system.

Merge tag 'cxl-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dan Williams:
"The highlights in terms of new functionality are support for the
standard CXL Performance Monitor definition that appeared in CXL 3.0,
support for device sanitization (wiping all data from a device),
secure-erase (re-keying encryption of user data), and support for
firmware update. The firmware update support is notable as it reuses
the simple sysfs_upload interface to just cat(1) a blob to a sysfs
file and pipe that to the device.
Additionally there are a substantial number of cleanups and
reorganizations to get ready for RCH error handling (RCH == Restricted
CXL Host == current shipping hardware generation / pre CXL-2.0
topologies) and type-2 (accelerator / vendor specific) devices.
For vendor specific devices they implement a subset of what the
generic type-3 (generic memory expander) driver expects. As a result
the rework decouples optional infrastructure from the core driver
context.
For RCH topologies, where the specification working group did not want
to confuse pre-CXL-aware operating systems, many of the standard
registers are hidden which makes support standard bus features like
AER (PCIe Advanced Error Reporting) difficult. The rework arranges for
the driver to help the PCI-AER core. Bjorn is on board with this
direction but a late regression disocvery means the completion of this
functionality needs to cook a bit longer, so it is code
reorganizations only for now.
Summary:
- Add infrastructure for supporting background commands along with
support for device sanitization and firmware update
- Introduce a CXL performance monitoring unit driver based on the
common definition in the specification.
- Land some preparatory cleanup and refactoring for the anticipated
arrival of CXL type-2 (accelerator devices) and CXL RCH (CXL-v1.1

Hi Linus, Please, pull the following patch that transforms a zero-length array into a C99 flexible-array member. This patch has been baking in linux-next for a while. Also, this addresses a build failure with Clang[1] by fixing multiple -Warray-bounds warnings in drivers/staging/ks7010/ks_wlan_net.c[2].

mm: Update do_vmi_align_munmap() return semantics
Since do_vmi_align_munmap() will always honor the downgrade request on the success, the callers no longer have to deal with confusing return codes. Since all callers that request downgrade actually want the lock to be dropped, change the downgrade to an unlock request. Note that the lock still needs to be held in read mode during the page table clean up to avoid races with a map request. Update do_vmi_align_munmap() to return 0 for success. Clean up the callers and comments to always expect the unlock to be honored on the success path. The error path will always leave the lock untouched. As part of the cleanup, the wrapper function do_vmi_munmap() and callers to the wrapper are also updated.

mm: Always downgrade mmap_lock if requested
Now that stack growth must always hold the mmap_lock for write, we can always downgrade the mmap_lock to read and safely unmap pages from the page table, even if we're next to a stack.

xtensa: fix lock_mm_and_find_vma in case VMA not found
MMU version of lock_mm_and_find_vma releases the mm lock before
returning when VMA is not found. Do the same in noMMU version.

xtensa: fix NOMMU build with lock_mm_and_find_vma() conversion
It turns out that xtensa has a really odd configuration situation: you
can do a no-MMU config, but still have the page fault code enabled.
Which doesn't sound all that sensible, but it turns out that xtensa can
have protection faults even without the MMU, and we have this:
config PFAULT
bool "Handle protection faults" if EXPERT && !MMU
default y
help
Handle protection faults. MMU configurations must enable it.
noMMU configurations may disable it if used memory map never
generates protection faults or faults are always fatal.
If unsure, say Y.
which completely violated my expectations of the page fault handling.
End result: Guenter reports that the xtensa no-MMU builds all fail with
arch/xtensa/mm/fault.c: In function ‘do_page_fault’:
arch/xtensa/mm/fault.c:133:8: error: implicit declaration of function ‘lock_mm_and_find_vma’
because I never exposed the new lock_mm_and_find_vma() function for the
no-MMU case.
Doing so is simple enough, and fixes the problem.

Merge tag 'pci-v6.5-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Export pcie_retrain_link() for use outside ASPM
- Add Data Link Layer Link Active Reporting as another way for
pcie_retrain_link() to determine the link is up
- Work around link training failures (especially on the ASMedia
ASM2824 switch) by training first at 2.5GT/s and then attempting
higher rates
Resource management:
- When we coalesce host bridge windows, remove invalidated resources
from the resource tree so future allocations work correctly
Hotplug:
- Cancel bringup sequence if card is not present, to keep from
blinking Power Indicator indefinitely
- Reassign bridge resources if necessary for ACPI hotplug
Driver binding:
- Convert platform_device .remove() callbacks to return void instead
of a mostly useless int
Power management:
- Reduce wait time for secondary bus to be ready to speed up resume
- Avoid putting EloPOS E2/S2/H2 (as well as Elo i2) PCIe Ports in
D3cold
- Call _REG when transitioning D-states so AML that uses the PCI
config space OpRegion works, which fixes some ASMedia GPIO
controllers after resume
Virtualization:
- Delay extra 250ms after FLR of Solidigm P44 Pro NVMe to avoid KVM
hang when guest is rebooted
- Add function 1 DMA alias quirk for Marvell 88SE9235
Error handling:
- Unexport pci_save_aer_state() since it's only used in drivers/pci/
- Drop recommendation for drivers to configure AER Capability, since
the PCI core does this for all devices
ASPM:
- Disable ASPM on MFD function removal to avoid use-after-free
- Tighten up pci_enable_link_state() and pci_disable_link_state()
interfaces so they don't enable/disable states the driver didn't
specify
- Avoid link retraining race that can happen if ASPM sets link
control parameters while the link is in the midst of training for
some other reason
Endpoint framework:
- Change "PCI Endpoint Virtual NTB driver" Kconfig prompt to be
different from "PCI Endpoint NTB driver"
- Automatically create a function specific attributes group for
endpoint drivers to avoid reference counting issues
- Fix many EPC test issues
- Return pci_epf_type_add_cfs() error if EPF has no driver
- Add kernel-doc for pci_epc_raise_irq() and pci_epc_map_msi_irq()
MSI vector parameters
- Pass EPF device ID to driver probe functions
- Return -EALREADY if EPC has already been started/stopped
- Add linkdown notifier support and use it in qcom-ep
- Add Bus Master Enable event support and use it in qcom-ep
- Add Qualcomm Modem Host Interface (MHI) endpoint driver
- Add Layerscape PME interrupt handling to manage link-up
notification
Cadence PCIe controller driver:
- Wait for link retrain to complete when working around the J721E
i2085 erratum with Gen2 mode
Faraday FTPC100 PCI controller driver:
- Release clock resources on error paths
Freescale i.MX6 PCIe controller driver:
- Save and restore Root Port MSI control to work around hardware defect
Intel VMD host bridge driver:
- Reset VMD config register between soft reboots
- Capture pci_reset_bus() return value instead of printing junk when
it fails
Qualcomm PCIe controller driver:
- Add SDX65 endpoint compatible string to DT binding
- Disable register write access after init for IP v2.3.3, v2.9.0
- Use DWC helpers for enabling/disabling writes to DBI registers
- Hide slot hotplug capability for IP v1.0.0, v1.9.0, v2.1.0, v2.3.2,
v2.3.3, v2.7.0, v2.9.0
- Reuse v2.3.2 post-init sequence for v2.4.0
Renesas R-Car PCIe controller driver:
- Remove unused static pcie_base and pcie_dev
Rockchip PCIe controller driver:
- Remove writes to unused registers
- Write endpoint Device ID using correct register
- Assert PCI Configuration Enable bit after probe so endpoint
responds instead of generating Request Retry Status messages
- Poll waiting for PHY PLLs to lock
- Update RK3399 example DT binding to be valid
- Use RK3399 PCIE_CLIENT_LEGACY_INT_CTRL to generate INTx instead of
manually generating PCIe message
- Use multiple windows to avoid address translation conflicts
- Use u32 (not u16) when accessing 32-bit registers
- Hide MSI-X Capability, since RK3399 can't generate MSI-X
- Set endpoint controller required alignment to 256
Synopsys DesignWare PCIe controller driver:
- Wait for link to come up only if we've initiated link training
Miscellaneous:
- Add pci_clear_master() stub for non-CONFIG_PCI"

perf tools changes and fixes for v6.5: 1st batch
Internal cleanup:
- Refactor PMU data management to handle hybrid systems in a generic way.
Do more work in the lexer so that legacy event types parse more easily.
A side-effect of this is that if a PMU is specified, scanning sysfs is
avoided improving start-up time.
- Fix hybrid metrics, for example, the TopdownL1 works for both performance
and efficiency cores on Intel machines. To support this, sort and regroup
events after parsing.
- Add reference count checking for the 'thread' data structure.
- Lots of fixes for memory leaks in various places thanks to the ASAN and
Ian's refcount checker.
- Reduce the binary size by replacing static variables with local or
dynamically allocated memory.
- Introduce shared_mutex for annotate data to reduce memory footprint.
- Make filesystem access library functions more thread safe.
Test:
- Organize cpu_map tests into a single suite.
- Add metric value validation test to check if the values are within correct
value ranges.
- Add perf stat stdio output test to check if event and metric names match.
- Add perf data converter JSON output test.
- Fix a lot of issues reported by shellcheck(1). This is a preparation to
enable shellcheck by default.
- Make the large x86 new instructions test optional at build time using
EXTRA_TESTS=1.
- Add a test for libpfm4 events.
perf script:
- Add 'dsoff' outpuf field to display offset from the DSO.
$ perf script -F comm,pid,event,ip,dsoff
ls 2695501 cycles: 152cc73ef4b5 (/usr/lib/x86_64-linux-gnu/ld-2.31.so+0x1c4b5)

ls 2695501 cycles: ffffffff992a6db0 ([kernel.kallsyms])
- Adjust width for large PID/TID values.
perf report:
- Robustify reading addr2line output for srcline by checking sentinel output
before the actual data and by using timeout of 1 second.
- Allow config terms (like 'name=ABC') with breakpoint events.
$ perf record -e mem:0x55feb98dd169:x/name=breakpoint/ -p 19646 -- sleep 1
perf annotate:
- Handle x86 instruction suffix like 'l' in 'movl' generally.
- Parse instruction operands properly even with a whitespace. This is needed
for llvm-objdump output.
- Support RISC-V binutils lookup using the triplet prefixes.
- Add '<' and '>' key to navigate to prev/next symbols in TUI.
- Fix instruction association and parsing for LoongArch.
perf stat:
- Add --per-cache aggregation option, optionally specify a cache level
like `--per-cache=L2`.
$ sudo perf stat --per-cache -a -e ls_dmnd_fills_from_sys.ext_cache_remote --\
taskset -c 0-15,64-79,128-143,192-207\
