2023-08-17Compiler Attributes: counted_by: Adjust name and identifier expansionKees Cook
GCC and Clang's current RFCs name this attribute "counted_by", and have moved away from using a string for the member name. Update the kernel's macros to match. Additionally provide a UAPI no-op macro for UAPI structs that will gain annotations.

2023-08-16um: refactor deprecated strncpy to memcpyJustin Stitt
Use `memcpy` since `console_buf` is not expected to be NUL-terminated and it more accurately describes what is happening with the buffers `console_buf` and `string` as per Kees' analysis [1]. Also mark char buffer as `__nonstring` as per Kees' suggestion [2]. This change now makes it more clear what this code does and that `console_buf` is not expected to be NUL-terminated.

2023-08-16um: vector: refactor deprecated strncpyJustin Stitt
`strncpy` is deprecated for use on NUL-terminated destination strings [1]. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on its destination buffer argument which is _not_ the case for `strncpy`! In this case, we are able to drop the now superfluous `... - 1` instances because `strscpy` will automatically truncate the last byte by setting it to a NUL byte if the source size exceeds the destination size or if the source string is not NUL-terminated. I've also opted to remove the seemingly useless char* casts. I'm not sure why they're present at all since (after expanding the `ifr_name` macro) `ifr.ifr_ifrn.ifrn_name` is a char* already. All in all, `strscpy` is a more robust and less ambiguous interface while also letting us remove some `... -1`'s which cleans things up a bit.

2023-08-15hardening: Move BUG_ON_DATA_CORRUPTION to hardening optionsMarco Elver
BUG_ON_DATA_CORRUPTION is turning detected corruptions of list data structures from WARNings into BUGs. This can be useful to stop further corruptions or even exploitation attempts. However, the option has less to do with debugging than with hardening. With the introduction of LIST_HARDENED, it makes more sense to move it to the hardening options, where it selects LIST_HARDENED instead. Without this change, combining BUG_ON_DATA_CORRUPTION with LIST_HARDENED alone wouldn't be possible, because DEBUG_LIST would always be selected by BUG_ON_DATA_CORRUPTION.

2023-08-15list: Introduce CONFIG_LIST_HARDENEDMarco Elver
Numerous production kernel configs (see [1, 2]) are choosing to enable CONFIG_DEBUG_LIST, which is also being recommended by KSPP for hardened configs [3]. The motivation behind this is that the option can be used as a security hardening feature (e.g. CVE-2019-2215 and CVE-2019-2025 are mitigated by the option [4]). The feature has never been designed with performance in mind, yet common list manipulation is happening across hot paths all over the kernel. Introduce CONFIG_LIST_HARDENED, which performs list pointer checking inline, and only upon list corruption calls the reporting slow path. To generate optimal machine code with CONFIG_LIST_HARDENED: 1. Elide checking for pointer values which upon dereference would result in an immediate access fault (i.e. minimal hardening checks). The trade-off is lower-quality error reports. 2. Use the __preserve_most function attribute (available with Clang, but not yet with GCC) to minimize the code footprint for calling the reporting slow path. As a result, function size of callers is reduced by avoiding saving registers before calling the rarely called reporting slow path. Note that all TUs in lib/Makefile already disable function tracing, including list_debug.c, and __preserve_most's implied notrace has no effect in this case. 3. Because the inline checks are a subset of the full set of checks in __list_*_valid_or_report(), always return false if the inline checks failed. This avoids redundant compare and conditional branch right after return from the slow path. As a side-effect of the checks being inline, if the compiler can prove some condition to always be true, it can completely elide some checks. Since DEBUG_LIST is functionally a superset of LIST_HARDENED, the Kconfig variables are changed to reflect that: DEBUG_LIST selects LIST_HARDENED, whereas LIST_HARDENED itself has no dependency on DEBUG_LIST. Running netperf with CONFIG_LIST_HARDENED (using a Clang compiler with "preserve_most") shows throughput improvements, in my case of ~7% on average (up to 20-30% on some test cases).

2023-08-15list_debug: Introduce inline wrappers for debug checksMarco Elver
Turn the list debug checking functions __list_*_valid() into inline functions that wrap the out-of-line functions. Care is taken to ensure the inline wrappers are always inlined, so that additional compiler instrumentation (such as sanitizers) does not result in redundant outlining. This change is preparation for performing checks in the inline wrappers. No functional change intended.

2023-08-15compiler_types: Introduce the Clang __preserve_most function attributeMarco Elver
[1]: "On X86-64 and AArch64 targets, this attribute changes the calling convention of a function. The preserve_most calling convention attempts to make the code in the caller as unintrusive as possible. This convention behaves identically to the C calling convention on how arguments and return values are passed, but it uses a different set of caller/callee-saved registers. This alleviates the burden of saving and recovering a large register set before and after the call in the caller. If the arguments are passed in callee-saved registers, then they will be preserved by the callee across the call. This doesn't apply for values returned in callee-saved registers. * On X86-64 the callee preserves all general purpose registers, except for R11. R11 can be used as a scratch register. Floating-point registers (XMMs/YMMs) are not preserved and need to be saved by the caller. * On AArch64 the callee preserve all general purpose registers, except x0-X8 and X16-X18." [1] https://clang.llvm.org/docs/AttributeReference.html#preserve-most Introduce the attribute to compiler_types.h as __preserve_most. Use of this attribute results in better code generation for calls to very rarely called functions, such as error-reporting functions, or rarely executed slow paths. Beware that the attribute conflicts with instrumentation calls inserted on function entry which do not use __preserve_most themselves. Notably, function tracing which assumes the normal C calling convention for the given architecture. Where the attribute is supported, __preserve_most will imply notrace. It is recommended to restrict use of the attribute to functions that should or already disable tracing. Note: The additional preprocessor check against architecture should not be necessary if __has_attribute() only returns true where supported; also see https://github.com/ClangBuiltLinux/linux/issues/1908. But until __has_attribute() does the right thing, we also guard by known-supported architectures to avoid build warnings on other architectures. The attribute may be supported by a future GCC version (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110899).

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 CFI fixes from Peter Zijlstra: "Fix kCFI/FineIBT weaknesses The primary bug Alyssa noticed was that with FineIBT enabled function prologues have a spurious ENDBR instruction: __cfi_foo: endbr64 subl $hash, %r10d jz 1f ud2 nop 1: foo: endbr64 <--- *sadface* This means that any indirect call that fails to target the __cfi symbol and instead targets (the regular old) foo+0, will succeed due to that second ENDBR. Fixing this led to the discovery of a single indirect call that was still doing this: ret_from_fork(). Since that's an assembly stub the compiler would not generate the proper kCFI indirect call magic and it would not get patched. Brian came up with the most comprehensive fix -- convert the thing to C with only a very thin asm wrapper. This ensures the kernel thread boostrap is a proper kCFI call. While discussing all this, Kees noted that kCFI hashes could/should be poisoned to seal all functions whose address is never taken, further limiting the valid kCFI targets -- much like we already do for IBT. So what was a 'simple' observation and fix cascaded into a bunch of inter-related CFI infrastructure fixes" * tag 'x86_urgent_for_6.5_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/cfi: Only define poison_cfi() if CONFIG_X86_KERNEL_IBT=y x86/fineibt: Poison ENDBR at +0 x86: Rewrite ret_from_fork() in C x86/32: Remove schedule_tail_wrapper() x86/cfi: Extend ENDBR sealing to kCFI x86/alternative: Rename apply_ibt_endbr() x86/cfi: Extend {JMP,CAKK}_NOSPEC comment

2023-07-14cifs: fix mid leak during reconnection after timeout thresholdShyam Prasad N
When the number of responses with status of STATUS_IO_TIMEOUT exceeds a specified threshold (NUM_STATUS_IO_TIMEOUT), we reconnect the connection. But we do not return the mid, or the credits returned for the mid, or reduce the number of in-flight requests. This bug could result in the server->in_flight count to go bad, and also cause a leak in the mids. This change moves the check to a few lines below where the response is decrypted, even of the response is read from the transform header. This way, the code for returning the mids can be reused. Also, the cifs_reconnect was reconnecting just the transport connection before. In case of multi-channel, this may not be what we want to do after several timeouts. Changed that to reconnect the session and the tree too. Also renamed NUM_STATUS_IO_TIMEOUT to a more appropriate name MAX_STATUS_IO_TIMEOUT.

2023-07-14block: queue data commands from the flush state machine at the headChristoph Hellwig
We used to insert the data commands following a pre-flush to the head of the queue until commit 1e82fadfc6b ("blk-mq: do not do head insertions post-pre-flush commands"). Not doing this seems to cause hangs of such commands on NFS workloads when exported from file systems with SATA SSDs. I have no idea why this would starve these workloads, but doing a semantic revert of this patch (which looks quite different due to various other changes) fixes the hangs.

The ida_alloc_range() function returns negative error codes on error. On success it returns values in the min to max range (inclusive). It never returns more then INT_MAX even if "max" is higher. It never returns values in the 0 to (min - 1) range. The bug is that "min" is an unsigned int so negative error codes will be promoted to high positive values errors treated as success.

fails Fix to record 0-length data to data_loc in fetch_store_string*() if it fails to get the string data. Currently those expect that the data_loc is updated by store_trace_args() if it returns the error code. However, that does not work correctly if the argument is an array of strings. In that case, store_trace_args() only clears the first entry of the array (which may have no error) and leaves other entries. So it should be cleared by fetch_store_string*() itself. Also, 'dyndata' and 'maxlen' in store_trace_args() should be updated only if it is used (ret > 0 and argument is a dynamic data.)
