tracing: Have memmapped ring buffer use ioctl of "R" range 0x20-2F
To prevent conflicts with other ioctl numbers to allow strace to have an
idea of what is happening, add the range of ioctls for the trace buffer
mapping from _IO("T", 0x1) to the range of "R" 0x20 - 0x2F.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for net-next: Patch #1 to #11 to shrink memory consumption for transaction objects: struct nft_trans_chain { /* size: 120 (-32), cachelines: 2, members: 10 */ struct nft_trans_elem { /* size: 72 (-40), cachelines: 2, members: 4 */ struct nft_trans_flowtable { /* size: 80 (-48), cachelines: 2, members: 5 */ struct nft_trans_obj { /* size: 72 (-40), cachelines: 2, members: 4 */ struct nft_trans_rule { /* size: 80 (-32), cachelines: 2, members: 6 */ struct nft_trans_set { /* size: 96 (-24), cachelines: 2, members: 8 */ struct nft_trans_table { /* size: 56 (-40), cachelines: 1, members: 2 */ struct nft_trans_elem can now be allocated from kmalloc-96 instead of kmalloc-128 slab. Series from Florian Westphal. For the record, I have mangled patch #1 to add nft_trans_container_*() and use if for every transaction object. I have also added BUILD_BUG_ON to ensure struct nft_trans always comes at the beginning of the container transaction object. And few minor cleanups, any new bugs are of my own. Patch #12 simplify check for SCTP GSO in IPVS, from Ismael Luceno. Patch #13 nf_conncount key length remains in the u32 bound, from Yunjian Wang. Patch #14 removes unnecessary check for CTA_TIMEOUT_L3PROTO when setting default conntrack timeouts via nfnetlink_cttimeout API, from Lin Ma. Patch #15 updates NFT_SECMARK_CTX_MAXLEN to 4096, SELinux could use larger secctx names than the existing 256 bytes length. Patch #16 adds a selftest to exercise nfnetlink_queue listeners leaving nfnetlink_queue, from Florian Westphal. Patch #17 increases hitcount from 255 to 65535 in xt_recent, from Phil Sutter. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

tcp_metrics: add netlink protocol spec in YAML
Add a protocol spec for tcp_metrics, so that it's accessible via YNL.
Useful at the very least for testing fixes.
In this episode of "10,000 ways to complicate netlink" the metric
nest has defines which are off by 1. iproute2 does:
struct rtattr *m[TCP_METRIC_MAX + 1 + 1];
parse_rtattr_nested(m, TCP_METRIC_MAX + 1, a);
for (i = 0; i < TCP_METRIC_MAX + 1; i++) {
// ...
attr = m[i + 1];
This is too weird to support in YNL, add a new set of defines
with _correct_ values to the official kernel header.

tcp_metrics: add UAPI to the header guard
tcp_metrics' header lacks the customary _UAPI in the header guard. This makes YNL build rules work less seamlessly. We can easily fix that on YNL side, but this could also be problematic if we ever needed to create a kernel-only tcp_metrics.h.

ethtool: Add an interface for flashing transceiver modules' firmware
CMIS compliant modules such as QSFP-DD might be running a firmware that can be updated in a vendor-neutral way by exchanging messages between the host and the module as described in section 7.3.1 of revision 5.2 of the CMIS standard. Add a pair of new ethtool messages that allow: * User space to trigger firmware update of transceiver modules * The kernel to notify user space about the progress of the process The user interface is designed to be asynchronous in order to avoid RTNL being held for too long and to allow several modules to be updated simultaneously. The interface is designed with CMIS compliant modules in mind, but kept generic enough to accommodate future use cases, if these arise.

ethtool: provide customized dim profile management
The NetDIM library, currently leveraged by an array of NICs, delivers
excellent acceleration benefits. Nevertheless, NICs vary significantly
in their dim profile list prerequisites.
Specifically, virtio-net backends may present diverse sw or hw device
implementation, making a one-size-fits-all parameter list impractical.
On Alibaba Cloud, the virtio DPU's performance under the default DIM
profile falls short of expectations, partly due to a mismatch in
parameter configuration.
I also noticed that ice/idpf/ena and other NICs have customized
profilelist or placed some restrictions on dim capabilities.
Motivated by this, I tried adding new params for "ethtool -C" that provides
a per-device control to modify and access a device's interrupt parameters.
Usage
========
The target NIC is named ethx.
Assume that ethx only declares support for rx profile setting
(with DIM_PROFILE_RX flag set in profile_flags) and supports modification
of usec and pkt fields.
1. Query the currently customized list of the device
$ ethtool -c ethx
...
rx-profile:
{.usec = 1, .pkts = 256, .comps = n/a,},
{.usec = 8, .pkts = 256, .comps = n/a,},
{.usec = 64, .pkts = 256, .comps = n/a,},
{.usec = 128, .pkts = 256, .comps = n/a,},
{.usec = 256, .pkts = 256, .comps = n/a,}
tx-profile: n/a
2. Tune
$ ethtool -C ethx rx-profile 1,1,n_2,n,n_3,3,n_4,4,n_n,5,n
"n" means do not modify this field.
$ ethtool -c ethx
...
rx-profile:
{.usec = 1, .pkts = 1, .comps = n/a,},
{.usec = 2, .pkts = 256, .comps = n/a,},
{.usec = 3, .pkts = 3, .comps = n/a,},
{.usec = 4, .pkts = 4, .comps = n/a,},
{.usec = 256, .pkts = 5, .comps = n/a,}
tx-profile: n/a
3. Hint
If the device does not support some type of customized dim profiles,
the corresponding "n/a" will display.
If the "n/a" field is being modified, -EOPNOTSUPP will be reported.

net/smc: Introduce IPPROTO_SMC
This patch allows to create smc socket via AF_INET, similar to the following code, /* create v4 smc sock */ v4 = socket(AF_INET, SOCK_STREAM, IPPROTO_SMC); /* create v6 smc sock */ v6 = socket(AF_INET6, SOCK_STREAM, IPPROTO_SMC); There are several reasons why we believe it is appropriate here: 1. For smc sockets, it actually use IPv4 (AF-INET) or IPv6 (AF-INET6) address. There is no AF_SMC address at all. 2. Create smc socket in the AF_INET(6) path, which allows us to reuse the infrastructure of AF_INET(6) path, such as common ebpf hooks. Otherwise, smc have to implement it again in AF_SMC path.

3) Several tweaks to the instruction-set.rst IETF doc to address
the Last Call review comments, from Dave Thaler.
4) Small batch of riscv64 BPF JIT optimizations in order to emit more
compressed instructions to the JITed image for better icache efficiency,
from Xiao Wang.
5) Sort bpftool C dump output from BTF, aiming to simplify vmlinux.h
diffing and forcing more natural type definitions ordering,
from Mykyta Yatsenko.
6) Use DEV_STATS_INC() macro in BPF redirect helpers to silence
a syzbot/KCSAN race report for the tx_errors counter,
from Jiang Yunshui.
7) Un-constify bpf_func_info in bpftool to fix compilation with LLVM 17+

mseal: wire up mseal syscall
Patch series "Introduce mseal", v10.
This patchset proposes a new mseal() syscall for the Linux kernel.
In a nutshell, mseal() protects the VMAs of a given virtual memory range
against modifications, such as changes to their permission bits.
Modern CPUs support memory permissions, such as the read/write (RW) and
no-execute (NX) bits. Linux has supported NX since the release of kernel
version 2.6.8 in August 2004 [1]. The memory permission feature improves
the security stance on memory corruption bugs, as an attacker cannot
simply write to arbitrary memory and point the code to it. The memory
must be marked with the X bit, or else an exception will occur.
Internally, the kernel maintains the memory permissions in a data
structure called VMA (vm_area_struct). mseal() additionally protects the
VMA itself against modifications of the selected seal type.
Memory sealing is useful to mitigate memory corruption issues where a
corrupted pointer is passed to a memory management system. For example,
such an attacker primitive can break control-flow integrity guarantees
since read-only memory that is supposed to be trusted can become writable
or .text pages can get remapped. Memory sealing can automatically be
applied by the runtime loader to seal .text and .rodata pages and
applications can additionally seal security critical data at runtime. A
similar feature already exists in the XNU kernel with the
VM_FLAGS_PERMANENT [3] flag and on OpenBSD with the mimmutable syscall
[4]. Also, Chrome wants to adopt this feature for their CFI work [2] and
this patchset has been designed to be compatible with the Chrome use case.
Two system calls are involved in sealing the map: mmap() and mseal().
The new mseal() is an syscall on 64 bit CPU, and with following signature:
int mseal(void addr, size_t len, unsigned long flags)
addr/len: memory range.
flags: reserved.
mseal() blocks following operations for the given memory range.
1> Unmapping, moving to another location, and shrinking the size,
via munmap() and mremap(), can leave an empty space, therefore can
be replaced with a VMA with a new set of attributes.
2> Moving or expanding a different VMA into the current location,
via mremap().
3> Modifying a VMA via mmap(MAP_FIXED).
4> Size expansion, via mremap(), does not appear to pose any specific
risks to sealed VMAs. It is included anyway because the use case is
unclear. In any case, users can rely on merging to expand a sealed VMA.
5> mprotect() and pkey_mprotect().
6> Some destructive madvice() behaviors (e.g. MADV_DONTNEED) for anonymous
memory, when users don't have write permission to the memory. Those
behaviors can alter region contents by discarding pages, effectively a
memset(0) for anonymous memory.
The idea that inspired this patch comes from Stephen Röttger’s work in
V8 CFI [5]. Chrome browser in ChromeOS will be the first user of this
API.
Indeed, the Chrome browser has very specific requirements for sealing,
which are distinct from those of most applications. For example, in the
case of libc, sealing is only applied to read-only (RO) or read-execute
(RX) memory segments (such as .text and .RELRO) to prevent them from
becoming writable, the lifetime of those mappings are tied to the lifetime
of the process.
Chrome wants to seal two large address space reservations that are managed
by different allocators. The memory is mapped RW- and RWX respectively
but write access to it is restricted using pkeys (or in the future ARM
permission overlay extensions). The lifetime of those mappings are not
tied to the lifetime of the process, therefore, while the memory is
sealed, the allocators still need to free or discard the unused memory.
For example, with madvise(DONTNEED).
However, always allowing madvise(DONTNEED) on this range poses a security
risk. For example if a jump instruction crosses a page boundary and the
second page gets discarded, it will overwrite the target bytes with zeros
and change the control flow. Checking write-permission before the discard
operation allows us to control when the operation is valid. In this case,
the madvise will only succeed if the executing thread has PKEY write
permissions and PKRU changes are protected in software by control-flow
integrity.
Although the initial version of this patch series is targeting the Chrome
browser as its first user, it became evident during upstream discussions
that we would also want to ensure that the patch set eventually is a
complete solution for memory sealing and compatible with other use cases.
The specific scenario currently in mind is glibc's use case of loading and
sealing ELF executables. To this end, Stephen is working on a change to
glibc to add sealing support to the dynamic linker, which will seal all
non-writable segments at startup. Once this work is completed, all
applications will be able to automatically benefit from these new
protections.
In closing, I would like to formally acknowledge the valuable
contributions received during the RFC process, which were instrumental in
shaping this patch:
Jann Horn: raising awareness and providing valuable insights on the
destructive madvise operations.
Liam R. Howlett: perf optimization.
Linus Torvalds: assisting in defining system call signature and scope.
Theo de Raadt: sharing the experiences and insight gained from
implementing mimmutable() in OpenBSD.
MM perf benchmarks
==================
This patch adds a loop in the mprotect/munmap/madvise(DONTNEED) to
check the VMAs’ sealing flag, so that no partial update can be made,
when any segment within the given memory range is sealed.
To measure the performance impact of this loop, two tests are developed.
[8]
The first is measuring the time taken for a particular system call,
by using clock_gettime(CLOCK_MONOTONIC). The second is using
PERF_COUNT_HW_REF_CPU_CYCLES (exclude user space). Both tests have
similar results.
The tests have roughly below sequence:
for (i = 0; i < 1000, i++)
create 1000 mappings (1 page per VMA)
start the sampling
for (j = 0; j < 1000, j++)
mprotect one mapping
stop and save the sample
delete 1000 mappings
calculates all samples.
Below tests are performed on Intel(R) Pentium(R) Gold 7505 @ 2.00GHz,
4G memory, Chromebook.

From 5.10 to 6.8
munmap: added 250-550 ns in time, or 500-1100 in cpu cycle, per vma.
mprotect: added 200-750 ns in time, or 500-1200 in cpu cycle, per vma.
madvise: added 33-50 ns in time, or 70-110 in cpu cycle, per vma.
In comparison to mseal, which adds 20-40 ns or 50-100 CPU cycles, the
increase from 5.10 to 6.8 is significantly larger, approximately ten times
greater for munmap and mprotect.
When I discuss the mm performance with Brian Makin, an engineer who worked
on performance, it was brought to my attention that such performance
benchmarks, which measuring millions of mm syscall in a tight loop, may
not accurately reflect real-world scenarios, such as that of a database
service. Also this is tested using a single HW and ChromeOS, the data
from another HW or distribution might be different. It might be best to
take this data with a grain of salt.
This patch (of 5):
Wire up mseal syscall for all architectures.

virtio-mem: support suspend+resume
With virtio-mem, primarily hibernation is problematic: as the machine shuts down, the virtio-mem device loses its state. Powering the machine back up is like losing a bunch of DIMMs. While there would be ways to add limited support, suspend+resume is more commonly used for VMs and "easier" to support cleanly. s2idle can be supported without any device dependencies. Similarly, one would expect suspend-to-ram (i.e., S3) to work out of the box. However, QEMU currently unplugs all device memory when resuming the VM, using a cold reset on the "wakeup" path. In order to support S3, we need a feature flag for the device to tell us if memory remains plugged when waking up. In the future, QEMU will implement this feature. So let's always support s2idle and support S3 with plugged memory only if the device indicates support. Block hibernation early using the PM notifier. Trying to hibernate now fails early: # echo disk > /sys/power/state [ 26.455369] PM: hibernation: hibernation entry [ 26.458271] virtio_mem virtio0: hibernation is not supported.

Merge tag 'bcachefs-2024-05-19' of https://evilpiepirate.org/git/bcachefs
Pull bcachefs updates from Kent Overstreet: - More safety fixes, primarily found by syzbot - Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is primarily for testing fsck/recovery in dry run mode, so it shouldn't change anything besides disabling writes and holding dirty metadata in memory. The idea here was to reduce the amount of activity if we can't write anything out, so that bringing up a filesystem in "super ro" mode would be more lilkely to work for data recovery - but norecovery is the correct option for this. - btree_trans->locked; we now track whether a btree_trans has any btree nodes locked, and this is used for improved assertions related to trans_unlock() and trans_relock(). We'll also be using it for improving how we work with lockdep in the future: we don't want lockdep to be tracking individual btree node locks because we take too many for lockdep to track, and it's not necessary since we have a cycle detector. - Trigger improvements that are prep work for online fsck - BTREE_TRIGGER_check_repair; this regularizes how we do some repair work for extents that goes with running triggers in fsck, and fixes some subtle issues with transaction restarts there. - bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot equivalence classes are for when snapshot deletion leaves behind redundant snapshot nodes, but snapshot deletion now cleans this up right away, so the abstraction doesn't need to leak. - Improvements to how we resume writing to the journal in recovery. The code for picking the new place to write when reading the journal is greatly simplified and we also store the position in the superblock for when we don't read the journal; this means that we preserve more of the journal for list_journal debugging. - Improvements to sysfs btree_cache and btree_node_cache, for debugging memory reclaim. - We now detect when we've blocked for 10 seconds on the allocator in the write path and dump some useful info. - Safety fixes for devices references: this is a big series that changes almost all device lookups to properly check if the device exists and take a reference to it. Previously we assumed that if a bkey exists that references a device then the device must exist, and this was enforced in .invalid methods, but this was incorrect because it meant device removal relied on accounting being correct to not leave keys pointing to invalid devices, and that's not something we can assume. Getting the "pointer to invalid device" checks out of our .invalid() methods fixes some long standing device removal bugs; the only outstanding bug with device removal now is a race between the discard path and deleting alloc info, which should be easily fixed. - The allocator now prefers not to expand the new member_info.btree_allocated bitmap, meaning if repair ever requires scanning for btree nodes (because of a corrupt interior nodes) we won't have to scan the whole device(s). - New coding style document, which among other things talks about the correct usage of assertions * tag 'bcachefs-2024-05-19' of https://evilpiepirate.org/git/bcachefs: (155 commits) bcachefs: add no_invalid_checks flag bcachefs: add counters for failed shrinker reclaim bcachefs: Fix sb_field_downgrade validation bcachefs: Plumb bch_validate_flags to sb_field_ops.validate() bcachefs: s/bkey_invalid_flags/bch_validate_flags bcachefs: fsync() should not return -EROFS bcachefs: Invalid devices are now checked for by fsck, not .invalid methods bcachefs: kill bch2_dev_bkey_exists() in bch2_check_fix_ptrs() bcachefs: kill bch2_dev_bkey_exists() in bch2_read_endio() bcachefs: bch2_dev_get_ioref() checks for device not present bcachefs: bch2_dev_get_ioref2(); io_read.c bcachefs: bch2_dev_get_ioref2(); debug.c bcachefs: bch2_dev_get_ioref2(); journal_io.c bcachefs: bch2_dev_get_ioref2(); io_write.c bcachefs: bch2_dev_get_ioref2(); btree_io.c bcachefs: bch2_dev_get_ioref2(); backpointers.c bcachefs: bch2_dev_get_ioref2(); alloc_background.c bcachefs: for_each_bset() declares loop iter bcachefs: Move BCACHEFS_STATFS_MAGIC value to UAPI magic.h bcachefs: Improve sysfs internal/btree_cache ... |

Merge tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing ring buffer updates from Steven Rostedt: "Add ring_buffer memory mappings. The tracing ring buffer was created based on being mostly used with the splice system call. It is broken up into page ordered sub-buffers and the reader swaps a new sub-buffer with an existing sub-buffer that's part of the write buffer. It then has total access to the swapped out sub-buffer and can do copyless movements of the memory into other mediums (file system, network, etc). The buffer is great for passing around the ring buffer contents in the kernel, but is not so good for when the consumer is the user space task itself. A new interface is added that allows user space to memory map the ring buffer. It will get all the write sub-buffers as well as reader sub-buffer (that is not written to). It can send an ioctl to change which sub-buffer is the new reader sub-buffer. The ring buffer is read only to user space. It only needs to call the ioctl when it is finished with a sub-buffer and needs a new sub-buffer that the writer will not write over. A self test program was also created for testing and can be used as an example for the interface to user space. The libtracefs (external to the kernel) also has code that interacts with this, although it is disabled until the interface is in a official release. It can be enabled by compiling the library with a special flag. This was used for testing applications that perform better with the buffer being mapped. Memory mapped buffers have limitations. The main one is that it can not be used with the snapshot logic. If the buffer is mapped, snapshots will be disabled. If any logic is set to trigger snapshots on a buffer, that buffer will not be allowed to be mapped" * tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Add cast to unsigned long addr passed to virt_to_page() ring-buffer: Have mmapped ring buffer keep track of missed events ring-buffer/selftest: Add ring-buffer mapping test Documentation: tracing: Add ring-buffer mapping tracing: Allow user-space mapping of the ring-buffer ring-buffer: Introducing ring-buffer mapping functions ring-buffer: Allocate sub-buffers with __GFP_COMP |

Merge tag 'cxl-for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dave Jiang:
- Three CXL mailbox passthrough commands are added to support the
populating and clearing of vendor debug logs:
- Get Log Capabilities
- Get Supported Log Sub-List Commands
- Clear Log
- Add support of Device Phyiscal Address (DPA) to Host Physical Address
(HPA) translation for CXL events of cxl_dram and cxl_general media.
This allows user space to figure out which CXL region the event
occured via trace event.
- Connect CXL to CPER reporting.
If a device is configured for firmware first, CXL event records are
not sent directly to the host. Those records are reported through EFI
Common Platform Error Records (CPER). Add support to route the CPER
records through the CXL sub-system in order to provide DPA to HPA
translation and also event decoding and tracing. This is useful for
users to determine which system issues may correspond to specific
hardware events.
- A number of misc cleanups and fixes:
- Fix for compile warning of cxl_security_ops
- Add debug message for invalid interleave granularity
- Enhancement to cxl-test event testing
- Add dev_warn() on unsupported mixed mode decoder
- Fix use of phys_to_target_node() for x86
- Use helper function for decoder enum instead of open coding
- Include missing headers for cxl-event
