2023-06-22syscalls: Remove file path comments from headersSohil Mehta1-99/+30
Source file locations for syscall definitions can change over a period of time. File paths in comments get stale and are hard to maintain long term. Also, their usefulness is questionable since it would be easier to locate a syscall definition using the SYSCALL_DEFINEx() macro. Remove all source file path comments from the syscall headers. Also, equalize the uneven line spacing (some of which is introduced due to the deletions). Signed-off-by: Sohil Mehta <[email protected]> Signed-off-by: Arnd Bergmann <[email protected]>

2023-06-21mptcp: introduce MPTCP_FULL_INFO getsockoptPaolo Abeni1-0/+24
Some user-space applications want to monitor the subflows utilization. Dumping the per subflow tcp_info is not enough, as the PM could close and re-create the subflows under-the-hood, fooling the accounting. Even checking the src/dst addresses used by each subflow could not be enough, because new subflows could re-use the same address/port of the just closed one.

2023-06-20block: change all __u32 annotations to __be32 in affs_hardblocks.hMichael Schmitz1-34/+34
The Amiga partition parser module uses signed int for partition sector address and count, which will overflow for disks larger than 1 TB. Use u64 as type for sector address and size to allow using disks up to 2 TB without LBD support, and disks larger than 2 TB with LBD. The RBD format allows to specify disk sizes up to 2^128 bytes (though native OS limitations reduce this somewhat, to max 2^68 bytes), so check for u64 overflow carefully to protect against overflowing sector_t. This bug was reported originally in 2012, and the fix was created by the RDB author, Joanne Dow <[email protected]>. A patch had been discussed and reviewed on linux-m68k at that time but never officially submitted (now resubmitted as patch 1 of this series). Patch 3 (this series) adds additional error checking and warning messages. One of the error checks now makes use of the previously unused rdb_CylBlocks field, which causes a 'sparse' warning (cast to restricted __be32). Annotate all 32 bit fields in affs_hardblocks.h as __be32, as the on-disk format of RDB and partition blocks is always big endian.

2023-06-19powerpc/ptrace: Expose HASHKEYR register to ptraceBenjamin Gray1-0/+1
The HASHKEYR register contains a secret per-process key to enable unique hashes per process. In general it should not be exposed to userspace at all and a regular process has no need to know its key. However, checkpoint restore in userspace (CRIU) functionality requires that a process be able to set the HASHKEYR of another process, otherwise existing hashes on the stack would be invalidated by a new random key. Exposing HASHKEYR in this way also makes it appear in core dumps, which is a security concern. Multiple threads may share a key, for example just after a fork() call, where the kernel cannot know if the child is going to return back along the parent's stack. If such a thread is coerced into making a core dump, then the HASHKEYR value will be readable and able to be used against all other threads sharing that key, effectively undoing any protection offered by hashst/hashchk. Therefore we expose HASHKEYR to ptrace when CONFIG_CHECKPOINT_RESTORE is enabled, providing a choice of increased security or migratable ROP protected processes. This is similar to how ARM exposes its PAC keys.

2023-06-19powerpc/ptrace: Expose DEXCR and HDEXCR registers to ptraceBenjamin Gray1-0/+1
The DEXCR register is of interest when ptracing processes. Currently it is static, but eventually will be dynamically controllable by a process. If a process can control its own, then it is useful for it to be ptrace-able to (e.g., for checkpoint-restore functionality). It is also relevant to core dumps (the NPHIE aspect in particular), which use the ptrace mechanism (or is it the other way around?) to decide what to dump. The HDEXCR is useful here too, as the NPHIE aspect may be set in the HDEXCR without being set in the DEXCR. Although the HDEXCR is per-cpu and we don't track it in the task struct (it's useless in normal operation), it would be difficult to imagine why a hypervisor would set it to different values within a guest. A hypervisor cannot safely set NPHIE differently at least, as that would break programs. Expose a read-only view of the userspace DEXCR and HDEXCR to ptrace. The HDEXCR is always readonly, and is useful for diagnosing the core dumps (as the HDEXCR may set NPHIE without the DEXCR setting it).

2023-06-16scsi: block: Improve ioprio value validity checksDamien Le Moal1-17/+33
The introduction of the macro IOPRIO_PRIO_LEVEL() in commit eca2040972b4 ("scsi: block: ioprio: Clean up interface definition") results in an iopriority level to always be masked using the macro IOPRIO_LEVEL_MASK, and thus to the kernel always seeing an acceptable value for an I/O priority level when checked in ioprio_check_cap(). Before this patch, this function would return an error for some (but not all) invalid values for a level valid range of [0..7]. Restore and improve the detection of invalid priority levels by introducing the inline function ioprio_value() to check an ioprio class, level and hint value before combining these fields into a single value to be used with ioprio_set() or AIOs. If an invalid value for the class, level or hint of an ioprio is detected, ioprio_value() returns an ioprio using the class IOPRIO_CLASS_INVALID, indicating an invalid value and causing ioprio_check_cap() to return -EINVAL.

Bump the minor version to declare event age tracking feature is now available. In kernel amdgpu driver, kfd_wait_on_events is used to support user space signal event wait function. For multiple threads waiting on same event scenery, race condition could occur since some threads after checking signal condition, before calling kfd_wait_on_events, the event interrupt could be fired and wake up other thread which are sleeping on this event. Then those threads could fall into sleep without waking up again. Adding event age tracking in both kernel and user mode, will help avoiding this race condition.

As the updated MIDI 2.0 spec has been published freshly, this is a catch up to add the support for new specs, especially UMP v1.1 features, on Linux kernel. The new UMP v1.1 introduced the concept of Function Blocks (FB), which is a kind of superset of USB MIDI 2.0 Group Terminal Blocks (GTB). The patch set adds the support for FB as the primary information source while keeping the parse of GTB as fallback. Also UMP v1.1 supports the groupless messages, the protocol switch, static FBs, and other new fundamental features, and those are supported as well.

UMP v1.1 spec allows to inform whether the function blocks are static and not dynamically updated. Add a new flag bit to snd_ump_endpoint_info to reflect that attribute, too. The flag is set when a USB MIDI device is still in the old MIDI 2.0 without UMP 1.1 support. Then the driver falls back to GTBs, and they are supposed to be static-only.

Also, the former reserved bit 0 for the client group filter is now used for groupless events. When the bit 0 is set, the groupless events are filtered out and skipped.

Implement SCM_PIDFD, a new type of CMSG type analogical to SCM_CREDENTIALS, but it contains pidfd instead of plain pid, which allows programmers not to care about PID reuse problem.

Since its introduction, the ovs module execute_hash action allowed hash algorithms other than the skb->l4_hash to be used. However, additional hash algorithms were not implemented. This means flows requiring different hash distributions weren't able to use the kernel datapath. Now, introduce support for symmetric hashing algorithm as an alternative hash supported by the ovs module using the flow dissector. Output of flow using l4_sym hash: recirc_id(0),in_port(3),eth(),eth_type(0x0800), ipv4(dst=64.0.0.0/192.0.0.0,proto=6,frag=no), packets:30473425, bytes:45902883702, used:0.000s, flags:SP., actions:hash(sym_l4(0)),recirc(0xd) Some performance testing with no GRO/GSO, two veths, single flow: hash(l4(0)): 4.35 GBits/s hash(l4_sym(0)): 4.24 GBits/s Signed-off-by: Aaron Conole <[email protected]> Signed-off-by: David S.

2023-06-09cachestat: implement cachestat syscallNhat Pham2-1/+18
There is currently no good way to query the page cache state of large file sets and directory trees. There is mincore(), but it scales poorly: the kernel writes out a lot of bitmap data that userspace has to aggregate, when the user really doesn not care about per-page information in that case. The user also needs to mmap and unmap each file as it goes along, which can be quite slow as well. Some use cases where this information could come in handy: * Allowing database to decide whether to perform an index scan or direct table queries based on the in-memory cache state of the index. * Visibility into the writeback algorithm, for performance issues diagnostic. * Workload-aware writeback pacing: estimating IO fulfilled by page cache (and IO to be done) within a range of a file, allowing for more frequent syncing when and where there is IO capacity, and batching when there is not. * Computing memory usage of large files/directory trees, analogous to the du tool for disk usage. More information about these use cases could be found in the following thread: https://lore.kernel.org/lkml/[email protected]/ This patch implements a new syscall that queries cache state of a file and summarizes the number of cached pages, number of dirty pages, number of pages marked for writeback, number of (recently) evicted pages, etc. in a given range. Currently, the syscall is only wired in for x86 architecture. NAME cachestat - query the page cache statistics of a file. SYNOPSIS #include <sys/mman.h> struct cachestat_range { __u64 off; __u64 len; }; struct cachestat { __u64 nr_cache; __u64 nr_dirty; __u64 nr_writeback; __u64 nr_evicted; __u64 nr_recently_evicted; }; int cachestat(unsigned int fd, struct cachestat_range *cstat_range, struct cachestat *cstat, unsigned int flags); DESCRIPTION cachestat() queries the number of cached pages, number of dirty pages, number of pages marked for writeback, number of evicted pages, number of recently evicted pages, in the bytes range given by `off` and `len`. An evicted page is a page that is previously in the page cache but has been evicted since. A page is recently evicted if its last eviction was recent enough that its reentry to the cache would indicate that it is actively being used by the system, and that there is memory pressure on the system. These values are returned in a cachestat struct, whose address is given by the `cstat` argument. The `off` and `len` arguments must be non-negative integers. If `len` > 0, the queried range is [`off`, `off` + `len`]. If `len` == 0, we will query in the range from `off` to the end of the file. The `flags` argument is unused for now, but is included for future extensibility. User should pass 0 (i.e no flag specified). Currently, hugetlbfs is not supported. Because the status of a page can change after cachestat() checks it but before it returns to the application, the returned values may contain stale information. RETURN VALUE On success, cachestat returns 0. On error, -1 is returned, and errno is set to indicate the error. ERRORS EFAULT cstat or cstat_args points to an invalid address. EINVAL invalid flags. EBADF invalid file descriptor. EOPNOTSUPP file descriptor is of a hugetlbfs file [[email protected]: replace rounddown logic with the existing helper] Link: https://lkml.kernel.org/r/[email protected] Link: https://lkml.kernel.org/r/[email protected] Signed-off-by: Nhat Pham <[email protected]> Acked-by: Johannes Weiner <[email protected]> Cc: Brian Foster <[email protected]> Cc: Matthew Wilcox (Oracle) <[email protected]> Cc: Michael Kerrisk <[email protected]> Signed-off-by: Andrew Morton <[email protected]>
