2024-11-25ksmbd: fix use-after-free in SMB request handlingYunseong Kim
A race condition exists between SMB request handling in `ksmbd_conn_handler_loop()` and the freeing of `ksmbd_conn` in the workqueue handler `handle_ksmbd_work()`. This leads to a UAF. - KASAN: slab-use-after-free Read in handle_ksmbd_work - KASAN: slab-use-after-free in rtlock_slowlock_locked This race condition arises as follows: - `ksmbd_conn_handler_loop()` waits for `conn->r_count` to reach zero: `wait_event(conn->r_count_q, atomic_read(&conn->r_count) == 0);` - Meanwhile, `handle_ksmbd_work()` decrements `conn->r_count` using `atomic_dec_return(&conn->r_count)`, and if it reaches zero, calls `ksmbd_conn_free()`, which frees `conn`. - However, after `handle_ksmbd_work()` decrements `conn->r_count`, it may still access `conn->r_count_q` in the following line: `waitqueue_active(&conn->r_count_q)` or `wake_up(&conn->r_count_q)` This results in a UAF, as `conn` has already been freed. The discovery of this UAF can be referenced in the following PR for syzkaller's support for SMB requests.

2024-11-25cifs: Fix parsing reparse point with native symlink in SMB1 non-UNICODE sessionPali Rohár
SMB1 NT_TRANSACT_IOCTL/FSCTL_GET_REPARSE_POINT even in non-UNICODE mode returns reparse buffer in UNICODE/UTF-16 format. This is because FSCTL_GET_REPARSE_POINT is NT-based IOCTL which does not distinguish between 8-bit non-UNICODE and 16-bit UNICODE modes and its path buffers are always encoded in UTF-16. This change fixes reading of native symlinks in SMB1 when UNICODE session is not active.

Current guard is opposite, which is currently correct but is less-safe. This change is required for adding support for creating WSL-style symlinks as symlinks also do not use device's major and minor numbers.

2024-11-25cifs: Add support for parsing WSL-style symlinksPali Rohár
Linux CIFS client currently does not implement readlink() for WSL-style symlinks. It is only able to detect that file is of WSL-style symlink, but is not able to read target symlink location. Add this missing functionality and implement support for parsing content of WSL-style symlink. The important note is that symlink target location stored for WSL symlink reparse point (IO_REPARSE_TAG_LX_SYMLINK) is in UTF-8 encoding instead of UTF-16 (which is used in whole SMB protocol and also in all other symlink styles). So for proper locale/cp support it is needed to do conversion from UTF-8 to local_nls. Signed-off-by: Pali Rohár <pali@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>

Check that path buffer has correct length (it is non-zero and in UNICODE mode it has even number of bytes) and check that buffer does not contain null character (UTF-16 null codepoint in UNICODE mode or null byte in non-unicode mode) because Linux cannot process symlink with null byte.

2024-11-25cifs: Fix parsing native symlinks relative to the exportPali Rohár
SMB symlink which has SYMLINK_FLAG_RELATIVE set is relative (as opposite of the absolute) and it can be relative either to the current directory (where is the symlink stored) or relative to the top level export path. To what it is relative depends on the first character of the symlink target path. If the first character is path separator then symlink is relative to the export, otherwise to the current directory. Linux (and generally POSIX systems) supports only symlink paths relative to the current directory where is symlink stored. Currently if Linux SMB client reads relative SMB symlink with first character as path separator (slash), it let as is. Which means that Linux interpret it as absolute symlink pointing from the root (/). But this location is different than the top level directory of SMB export (unless SMB export was mounted to the root) and thefore SMB symlinks relative to the export are interpreted wrongly by Linux SMB client. Fix this problem. As Linux does not have equivalent of the path relative to the top of the mount point, convert such symlink target path relative to the current directory. Do this by prepending "../" pattern N times before the SMB target path, where N is the number of path separators found in SMB symlink path. So for example, if SMB share is mounted to Linux path /mnt/share/, symlink is stored in file /mnt/share/test/folder1/symlink (so SMB symlink path is test\folder1\symlink) and SMB symlink target points to \test\folder2\file, then convert symlink target path to Linux path ../../test/folder2/file. Deduplicate code for parsing SMB symlinks in native form from functions smb2_parse_symlink_response() and parse_reparse_native_symlink() into new function smb2_parse_native_symlink() and pass into this new function a new full_path parameter from callers, which specify SMB full path where is symlink stored. This change fixes resolving of the native Windows symlinks relative to the top level directory of the SMB share.

2024-11-25smb: client: fix NULL ptr deref in crypto_aead_setkey()Paulo Alcantara
Neither SMB3.0 or SMB3.02 supports encryption negotiate context, so when SMB2_GLOBAL_CAP_ENCRYPTION flag is set in the negotiate response, the client uses AES-128-CCM as the default cipher. See MS-SMB2 3.3.5.4. Commit b0abcd65ec54 ("smb: client: fix UAF in async decryption") added a @server->cipher_type check to conditionally call smb3_crypto_aead_allocate(), but that check would always be false as @server->cipher_type is unset for SMB3.02. Fix the following KASAN splat by setting @server->cipher_type for SMB3.02 as well. mount.cifs //srv/share /mnt -o vers=3.02,seal,...

2024-11-25x86/Documentation: Update algo in init_size description of boot protocolAndy Shevchenko
The init_size description of boot protocol has an example of the runtime start address for the compressed bzImage. For non-relocatable kernel it relies on the pref_address value (if not 0), but for relocatable case only pays respect to the load_addres and kernel_alignment, and it is inaccurate for the latter. Boot loader must consider the pref_address as the Linux kernel relocates to it before being decompressed as nicely described in this commit message a year ago: 43b1d3e68ee7 ("kexec: Allocate kernel above bzImage's pref_address") Due to this documentation inaccuracy some of the bootloaders (*) made a mistake in the calculations and if kernel image is big enough, this may lead to unbootable configurations. *) In particular, kexec-tools missed that and resently got a couple of changes which will be part of v2.0.30 release. For the record, commit 43b1d3e68ee7 only fixed the kernel kexec implementation and also missed to update the init_size description. While at it, make an example C-like looking as it's done elsewhere in the document and fix indentation as presribed by the reStructuredText specifications, so the syntax highliting will work properly.

2024-11-25x86: fix off-by-one in access_ok()David Laight
When the size isn't a small constant, __access_ok() will call valid_user_address() with the address after the last byte of the user buffer. It is valid for a buffer to end with the last valid user address so valid_user_address() must allow accesses to the base of the guard page. [ This introduces an off-by-one in the other direction for the plain non-sized accesses, but since we have that guard region that is a whole page, those checks "allowing" accesses to that guard region don't really matter. The access will fault anyway, whether to the guard page or if the address has been masked to all ones - Linus ] Fixes: 86e6b1547b3d0 ("x86: fix user address masking non-canonical speculation issue") Signed-off-by: David Laight <david.laight@aculab.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2024-11-25futex: improve user space accessesLinus Torvalds
Josh Poimboeuf reports that he got a "will-it-scale.per_process_ops 1.9% improvement" report for his patch that changed __get_user() to use pointer masking instead of the explicit speculation barrier. However, that patch doesn't actually work in the general case, because some (very bad) architecture-specific code actually depends on __get_user() also working on kernel addresses. A profile showed that the offending __get_user() was the futex code, which really should be fixed up to not use that horrid legacy case. Rewrite futex_get_value_locked() to use the modern user acccess helpers, and inline it so that the compiler not only avoids the function call for a few instructions, but can do CSE on the address masking. It also turns out the x86 futex functions have unnecessary barriers in other places, so let's fix those up too.
