Revert "fs: don't block i_writecount during exec"
This reverts commit 2a010c41285345da60cece35575b4e0af7e7bf44. Rui Ueyama <rui314@gmail.com> writes: > I'm the creator and the maintainer of the mold linker > (https://github.com/rui314/mold). Recently, we discovered that mold > started causing process crashes in certain situations due to a change > in the Linux kernel. Here are the details: > > - In general, overwriting an existing file is much faster than > creating an empty file and writing to it on Linux, so mold attempts to > reuse an existing executable file if it exists. > > - If a program is running, opening the executable file for writing > previously failed with ETXTBSY.

Since changes to mmap'ed files are > immediately visible to other processes, any processes running that > file would almost certainly crash in a very mysterious way. > Identifying the cause of these random crashes took us a few days. > > Rejecting writes to an executable file that is currently running is a > well-known behavior, and Linux had operated that way for a very long > time. So, I don’t believe relying on this behavior was our mistake; > rather, I see this as a regression in the Linux kernel. Quoting myself from commit 2a010c412853 ("fs: don't block i_writecount during exec") > Yes, someone in userspace could potentially be relying on this. It's not > completely out of the realm of possibility but let's find out if that's > actually the case and not guess. It seems we found out that someone is relying on this obscure behavior.

NFSD 6.13 Release Notes
Jeff Layton contributed a scalability improvement to NFSD's NFSv4 backchannel session implementation. This improvement is intended to increase the rate at which NFSD can safely recall NFSv4 delegations from clients, to avoid the need to revoke them. Revoking requires a slow state recovery process. A wide variety of bug fixes and other incremental improvements make up the bulk of commits in this series. As always I am grateful to the NFSD contributors, reviewers, testers, and bug reporters who participated during this cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmdEgLQACgkQM2qzM29m f5cwmg/9HcfG7blepU/2qNHopzSYRO5vZw1YNJQ5/Wi3bmqIea83lf8OcCY1G/aj 6K+jnenzHrwfhaA4u7N2FPXPVl8sPSMuOrJXY5zC4yE5QnIbranjcyEW5l5zlj3n ukkTYQgjUsKre3pHlvn3JmDHfUhNPEfzirsJeorP7DS3omne+OFA1LNncNP6emRu h0aEC6EJ43zUkYiz9nZYqPwIAwrUIA0WOrvVnq7vsi6gR4/Muk7nS+X/y4qFjli3 9enVskEv8sFmmOAIMK3CHJq+exEeKtKEKUuYkD23QgPt2R4+IwqS70o9IM/S1ypf APiv958BIhxm/SwUn1IjoxIckTB5EdksMxU5/4qGr1ZxprPG4/ruKO80BkrxLzW2 n1HmJ4ZNnpWPQvHN7RQ0WOsPNzL8byxJbGr1bpNgU4AGXnTFWPrAnB6juiyX4xb+ YNfgkQGDY79o7r1OJ5UUdCyx0QBSnaLNACTGm2u2FpI/ukMFPdrWIE99QbBgSe1p MgWaiPwSY+9crFfGPJeQ4t6/siRAec6L3RO9KT9Epcd2S7/Uts3NXYRdJfwZ+Qza TkPY2bm7T/WCcMhW7DN372hqgfRHPWOf4tacJ1Tob+As1d6p6qXEX2zi6piCCOLj dmTVDSVPClRXt8YigF9WqosyWv1jUzSnh9ne+eYPBpj93Ag2YBY= =wBvS -----END PGP SIGNATURE----- Merge tag 'nfsd-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Jeff Layton contributed a scalability improvement to NFSD's NFSv4 backchannel session implementation.

f2fs-for-6.13-rc1
This series introduces a device aliasing feature where user can carve out
partitions but reclaim the space back by deleting aliased file in root dir.
In addition to that, there're numerous minor bug fixes in zoned device support,
checkpoint=disable, extent cache management, fiemap, and lazytime mount option.
The full list of noticeable changes can be found below.
Enhancement:
- introduce device aliasing file
- add stats in debugfs to show multiple devices
- add a sysfs node to limit max read extent count per-inode
- modify f2fs_is_checkpoint_ready logic to allow more data to be written with the CP disable
- decrease spare area for pinned files for zoned devices
Bug fix:
- Revert "f2fs: remove unreachable lazytime mount option parsing"
- adjust unusable cap before checkpoint=disable mode
- fix to drop all discards after creating snapshot on lvm device
- fix to shrink read extent node in batches
- fix changing cursegs if recovery fails on zoned device
- fix to adjust appropriate length for fiemap
- fix fiemap failure issue when page size is 16KB
- fix to avoid forcing direct write to use buffered IO on inline_data inode
- fix to map blocks correctly for direct write
- fix to account dirty data in __get_secs_required()
- fix null-ptr-deref in f2fs_submit_page_bio()
- f2fs: compress: fix inconsistent update of i_blocks in release_compress_blocks and reserve_compress_blocks

exfat: reduce FAT chain traversal
Before this commit, ->dir and ->entry of exfat_inode_info record the first cluster of the parent directory and the directory entry index starting from this cluster. The directory entry set will be gotten during write-back-inode/rmdir/ unlink/rename. If the clusters of the parent directory are not continuous, the FAT chain will be traversed from the first cluster of the parent directory to find the cluster where ->entry is located. After this commit, ->dir records the cluster where the first directory entry in the directory entry set is located, and ->entry records the directory entry index in the cluster, so that there is almost no need to access the FAT when getting the directory entry set.

exfat: move exfat_chain_set() out of __exfat_resolve_path()
__exfat_resolve_path() mixes two functions. The first one is to resolve and check if the path is valid. The second one is to output the cluster assigned to the directory. The second one is only needed when need to traverse the directory entries, and calling exfat_chain_set() so early causes p_dir to be passed as an argument multiple times, increasing the complexity of the code. This commit moves the call to exfat_chain_set() before traversing directory entries.

exfat: rename argument name for exfat_move_file and exfat_rename_file
In this exfat implementation, the relationship between inode and ei is ei=EXFAT_I(inode). However, in the arguments of exfat_move_file() and exfat_rename_file(), argument 'inode' indicates the parent directory, but argument 'ei' indicates the target file to be renamed. They do not have the above relationship, which is not friendly to code readers. So this commit renames 'inode' to 'parent_inode', making the argument name match its role.

exfat: fix uninit-value in __exfat_get_dentry_set
There is no check if stream size and start_clu are invalid. If start_clu is EOF cluster and stream size is 4096, It will cause uninit value access. because ei->hint_femp.eidx could be 128(if cluster size is 4K) and wrong hint will allocate next cluster. and this cluster will be same with the cluster that is allocated by exfat_extend_valid_size(). The previous patch will check invalid start_clu, but for clarity, initialize hint_femp.eidx to zero.

In the case of the directory size is greater than or equal to the cluster size, if start_clu becomes an EOF cluster(an invalid cluster) due to file system corruption, then the directory entry where ei->hint_femp.eidx hint is outside the directory, resulting in an out-of-bounds access, which may cause further file system corruption.

f2fs: fix to drop all discards after creating snapshot on lvm device
Piergiorgio reported a bug in bugzilla as below: ------------[ cut here ]------------ WARNING: CPU: 2 PID: 969 at fs/f2fs/segment.c:1330 RIP: 0010:__submit_discard_cmd+0x27d/0x400 [f2fs] Call Trace: __issue_discard_cmd+0x1ca/0x350 [f2fs] issue_discard_thread+0x191/0x480 [f2fs] kthread+0xcf/0x100 ret_from_fork+0x31/0x50 ret_from_fork_asm+0x1a/0x30 w/ below testcase, it can reproduce this bug quickly: - pvcreate /dev/vdb - vgcreate myvg1 /dev/vdb - lvcreate -L 1024m -n mylv1 myvg1 - mount /dev/myvg1/mylv1 /mnt/f2fs - dd if=/dev/zero of=/mnt/f2fs/file bs=1M count=20 - sync - rm /mnt/f2fs/file - sync - lvcreate -L 1024m -s -n mylv1-snapshot /dev/myvg1/mylv1 - umount /mnt/f2fs The root cause is: it will update discard_max_bytes of mounted lvm device to zero after creating snapshot on this lvm device, then, __submit_discard_cmd() will pass parameter @nr_sects w/ zero value to __blkdev_issue_discard(), it returns a NULL bio pointer, result in panic. This patch changes as below for fixing: 1. Let's drop all remained discards in f2fs_unfreeze() if snapshot of lvm device is created. 2. Checking discard_max_bytes before submitting discard during __submit_discard_cmd().

f2fs: add a sysfs node to limit max read extent count per-inode
Quoted:
"at this time, there are still 1086911 extent nodes in this zombie
extent tree that need to be cleaned up.
crash_arm64_sprd_v8.0.3++> extent_tree.node_cnt ffffff80896cc500
node_cnt = {
counter = 1086911
},
"
As reported by Xiuhong, there will be a huge number of extent nodes
in extent tree, it may potentially cause:
- slab memory fragments
- extreme long time shrink on extent tree
- low mapping efficiency
Let's add a sysfs node to limit max read extent count for each inode,
by default, value of this threshold is 10240, it can be updated
according to user's requirement.

Summary
* sysctl ctl_table constification
Constifying ctl_table structs prevents the modification of proc_handler
function pointers. All ctl_table struct arguments are const qualified in the
sysctl API in such a way that the ctl_table arrays being defined elsewhere
and passed through sysctl can be constified one-by-one. We kick the
constification off by qualifying user_table in kernel/ucount.c and expect all
the ctl_tables to be constified in the coming releases.
* Misc fixes
Adjust comments in two places to better reflect the code. Remove superfluous
dput calls. Remove Luis from sysctl maintainership. Replace comments about
holding a lock with calls to lockdep_assert_held.
* Testing
All these went through 0-day and they have all been in linux-next for at
least 1 month (since Oct-24). I also rand these through the sysctl selftest
for x86_64.

smb: prevent use-after-free due to open_cached_dir error paths
If open_cached_dir() encounters an error parsing the lease from the server, the error handling may race with receiving a lease break, resulting in open_cached_dir() freeing the cfid while the queued work is pending. Update open_cached_dir() to drop refs rather than directly freeing the cfid. Have cached_dir_lease_break(), cfids_laundromat_worker(), and invalidate_all_cached_dirs() clear has_lease immediately while still holding cfids->cfid_list_lock, and then use this to also simplify the reference counting in cfids_laundromat_worker() and invalidate_all_cached_dirs(). Fixes this KASAN splat (which manually injects an error and lease break in open_cached_dir()): ================================================================== BUG: KASAN: slab-use-after-free in smb2_cached_lease_break+0x27/0xb0 Read of size 8 at addr ffff88811cc24c10 by task kworker/3:1/65 CPU: 3 UID: 0 PID: 65 Comm: kworker/3:1 Not tainted 6.12.0-rc6-g255cf264e6e5-dirty #87 Hardware name: VMware, Inc.

smb: Don't leak cfid when reconnect races with open_cached_dir
open_cached_dir() may either race with the tcon reconnection even before
compound_send_recv() or directly trigger a reconnection via
SMB2_open_init() or SMB_query_info_init().
The reconnection process invokes invalidate_all_cached_dirs() via
cifs_mark_open_files_invalid(), which removes all cfids from the
cfids->entries list but doesn't drop a ref if has_lease isn't true. This
results in the currently-being-constructed cfid not being on the list,
but still having a refcount of 2. It leaks if returned from
open_cached_dir().
Fix this by setting cfid->has_lease when the ref is actually taken; the
cfid will not be used by other threads until it has a valid time.
Addresses these kmemleaks:

smb: client: handle max length for SMB symlinks
We can't use PATH_MAX for SMB symlinks because
(1) Windows Server will fail FSCTL_SET_REPARSE_POINT with
STATUS_IO_REPARSE_DATA_INVALID when input buffer is larger than
16K, as specified in MS-FSA 2.1.5.10.37.
(2) The client won't be able to parse large SMB responses that
includes SMB symlink path within SMB2_CREATE or SMB2_IOCTL
responses.
Fix this by defining a maximum length value (4060) for SMB symlinks
that both client and server can handle.

smb: client: improve compound padding in encryption
After commit f7f291e14dde ("cifs: fix oops during encryption"), the
encryption layer can handle vmalloc'd buffers as well as kmalloc'd
buffers, so there is no need to inefficiently squash request iovs
into a single one to handle padding in compound requests.

smb3: request handle caching when caching directories
This client was only requesting READ caching, not READ and HANDLE caching in the LeaseState on the open requests we send for directories. To delay closing a handle (e.g. for caching directory contents) we should be requesting HANDLE as well as READ (as we already do for deferred close of files). See MS-SMB2 3.3.1.4 e.g. Cc: stable@vger.kernel.org Signed-off-by: Steve French <stfrench@microsoft.com> |

cifs: Recognize SFU char/block devices created by Windows NFS server on Windows Server <<2012
Windows NFS server versions on Windows Server older than 2012 release use for storing char and block devices modified SFU format, not compatible with the original SFU. Windows NFS server on Windows Server 2012 and new versions use different format (reparse points), not related to SFU-style. SFU / SUA / Interix subsystem stores the major and major numbers as pair of 64-bit integer, but Windows NFS server stores as pair of 32-bit integers. Which makes char and block devices between Windows NFS server <<2012 and Windows SFU/SUA/Interix subsytem incompatible. So improve Linux SMB client. When SFU mode is enabled (mount option -o sfu is specified) then recognize also these kind of char and block devices and its major and minor numbers, which are used by Windows Server versions older than 2012.
