2025-01-27tools: ynl: c: correct reverse decode of empty attrsJakub Kicinski
netlink reports which attribute was incorrect by sending back an attribute offset. Offset points to the address of struct nlattr, but to interpret the type we also need the nesting path. Attribute IDs have different meaning in different nests of the same message. Correct the condition for "is the offset within current attribute". ynl_attr_data_len() does not include the attribute header, so the end offset was off by 4 bytes. This means that we'd always skip over flags and empty nests. The devmem tests, for example, issues an invalid request with empty queue nests, resulting in the following error: YNL failed: Kernel error: missing attribute: .queues.ifindex The message is incorrect, "queues" nest does not have an "ifindex" attribute defined. With this fix we decend correctly into the nest: YNL failed: Kernel error: missing attribute: .queues.id Fixes: 86878f14d71a ("tools: ynl: user space helpers") Reviewed-by: Donald Hunter <donald.hunter@gmail.com> Link: https://patch.msgid.link/20250124012130.1121227-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "This is slightly smaller than usual, with the most interesting work being still around RTNL scope reduction. Core: - More core refactoring to reduce the RTNL lock contention, including preparatory work for the per-network namespace RTNL lock, replacing RTNL lock with a per device-one to protect NAPI-related net device data and moving synchronize_net() calls outside such lock. - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge and more specific TCP coverage. - Reduce network namespace tear-down time by removing per-subsystems synchronize_net() in tipc and sched. - Add flow label selector support for fib rules, allowing traffic redirection based on such header field. Netfilter: - Do not remove netdev basechain when last device is gone, allowing netdev basechains without devices. - Revisit the flowtable teardown strategy, dealing better with fin, reset and re-open events. - Scale-up IP-vs connection dumping by avoiding linear search on each restart. Protocols: - A significant XDP socket refactor, consolidating and optimizing several helpers into the core - Better scaling of ICMP rate-limiting, by removing false-sharing in inet peers handling. - Introduces netlink notifications for multicast IPv4 and IPv6 address changes. - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing aggregation and fragmentation of the inner IP. - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to avoid local port exhaustion issues when the average connection lifetime is very short. - Support updating keys (re-keying) for connections using kernel TLS (for TLS 1.3 only). - Support ipv4-mapped ipv6 address clients in smc-r v2. - Add support for jumbo data packet transmission in RxRPC sockets, gluing multiple data packets in a single UDP packet. - Support RxRPC RACK-TLP to manage packet loss and retransmission in conjunction with the congestion control algorithm. Driver API: - Introduce a unified and structured interface for reporting PHY statistics, exposing consistent data across different H/W via ethtool. - Make timestamping selectable, allow the user to select the desired hwtstamp provider (PHY or MAC) administratively. - Add support for configuring a header-data-split threshold (HDS) value via ethtool, to deal with partial or buggy H/W implementation. - Consolidate DSA drivers Energy Efficiency Ethernet support. - Add EEE management to phylink, making use of the phylib implementation. - Add phylib support for in-band capabilities negotiation. - Simplify how phylib-enabled mac drivers expose the supported interfaces.

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm Pull lsm updates from Paul Moore: - Improved handling of LSM "secctx" strings through lsm_context struct The LSM secctx string interface is from an older time when only one LSM was supported, migrate over to the lsm_context struct to better support the different LSMs we now have and make it easier to support new LSMs in the future. These changes explain the Rust, VFS, and networking changes in the diffstat. - Only build lsm_audit.c if CONFIG_SECURITY and CONFIG_AUDIT are enabled Small tweak to be a bit smarter about when we build the LSM's common audit helpers. - Check for absurdly large policies from userspace in SafeSetID SafeSetID policies rules are fairly small, basically just "UID:UID", it easy to impose a limit of KMALLOC_MAX_SIZE on policy writes which helps quiet a number of syzbot related issues. While work is being done to address the syzbot issues through other mechanisms, this is a trivial and relatively safe fix that we can do now. - Various minor improvements and cleanups A collection of improvements to the kernel selftests, constification of some function parameters, removing redundant assignments, and local variable renames to improve readability. * tag 'lsm-pr-20250121' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: lockdown: initialize local array before use to quiet static analysis safesetid: check size of policy writes net: corrections for security_secid_to_secctx returns lsm: rename variable to avoid shadowing lsm: constify function parameters security: remove redundant assignment to return variable lsm: Only build lsm_audit.c if CONFIG_SECURITY and CONFIG_AUDIT are set selftests: refactor the lsm `flags_overset_lsm_set_self_attr` test binder: initialize lsm_context structure rust: replace lsm context+len with lsm_context lsm: secctx provider check on release lsm: lsm_context in security_dentry_init_security lsm: use lsm_context in security_inode_getsecctx lsm: replace context+len with lsm_context lsm: ensure the correct LSM context releaser
2025-01-21Merge tag 'ftrace-v6.14' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ftrace updates from Steven Rostedt: - Have fprobes built on top of function graph infrastructure The fprobe logic is an optimized kprobe that uses ftrace to attach to functions when a probe is needed at the start or end of the function. The fprobe and kretprobe logic implements a similar method as the function graph tracer to trace the end of the function. That is to hijack the return address and jump to a trampoline to do the trace when the function exits. To do this, a shadow stack needs to be created to store the original return address. Fprobes and function graph do this slightly differently. Fprobes (and kretprobes) has slots per callsite that are reserved to save the return address. This is fine when just a few points are traced. But users of fprobes, such as BPF programs, are starting to add many more locations, and this method does not scale. The function graph tracer was created to trace all functions in the kernel. In order to do this, when function graph tracing is started, every task gets its own shadow stack to hold the return address that is going to be traced. The function graph tracer has been updated to allow multiple users to use its infrastructure. Now have fprobes be one of those users. This will also allow for the fprobe and kretprobe methods to trace the return address to become obsolete. With new technologies like CFI that need to know about these methods of hijacking the return address, going toward a solution that has only one method of doing this will make the kernel less complex. - Cleanup with guard() and free() helpers There were several places in the code that had a lot of "goto out" in the error paths to either unlock a lock or free some memory that was allocated. But this is error prone. Convert the code over to use the guard() and free() helpers that let the compiler unlock locks or free memory when the function exits. - Remove disabling of interrupts in the function graph tracer When function graph tracer was first introduced, it could race with interrupts and NMIs. To prevent that race, it would disable interrupts and not trace NMIs. But the code has changed to allow NMIs and also interrupts. This change was done a long time ago, but the disabling of interrupts was never removed. Remove the disabling of interrupts in the function graph tracer is it is not needed. This greatly improves its performance. - Allow the :mod: command to enable tracing module functions on the kernel command line. The function tracer already has a way to enable functions to be traced in modules by writing ":mod:<module>" into set_ftrace_filter. That will enable either all the functions for the module if it is loaded, or if it is not, it will cache that command, and when the module is loaded that matches <module>, its functions will be enabled. This also allows init functions to be traced. But currently events do not have that feature. Because enabling function tracing can be done very early at boot up (before scheduling is enabled), the commands that can be done when function tracing is started is limited. Having the ":mod:" command to trace module functions as they are loaded is very useful. Update the kernel command line function filtering to allow it. * tag 'ftrace-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (26 commits) ftrace: Implement :mod: cache filtering on kernel command line tracing: Adopt __free() and guard() for trace_fprobe.c bpf: Use ftrace_get_symaddr() for kprobe_multi probes ftrace: Add ftrace_get_symaddr to convert fentry_ip to symaddr Documentation: probes: Update fprobe on function-graph tracer selftests/ftrace: Add a test case for repeating register/unregister fprobe selftests: ftrace: Remove obsolate maxactive syntax check tracing/fprobe: Remove nr_maxactive from fprobe fprobe: Add fprobe_header encoding feature fprobe: Rewrite fprobe on function-graph tracer s390/tracing: Enable HAVE_FTRACE_GRAPH_FUNC ftrace: Add CONFIG_HAVE_FTRACE_GRAPH_FUNC bpf: Enable kprobe_multi feature if CONFIG_FPROBE is enabled tracing/fprobe: Enable fprobe events with CONFIG_DYNAMIC_FTRACE_WITH_ARGS tracing: Add ftrace_fill_perf_regs() for perf event tracing: Add ftrace_partial_regs() for converting ftrace_regs to pt_regs fprobe: Use ftrace_regs in fprobe exit handler fprobe: Use ftrace_regs in fprobe entry handler fgraph: Pass ftrace_regs to retfunc fgraph: Replace fgraph_ret_regs with ftrace_regs ...

We can make this lockless. The simple search case can just use a sequence counter to detect concurrent changes to the rbtree For walking the list of mount namespaces sequentially via nsfs we keep a separate rcu list as rb_prev() and rb_next() aren't usable safely with rcu. Currently there is no primitive for retrieving the previous list member. To do this we need a new deletion primitive that doesn't poison the prev pointer and a corresponding retrieval helper Since creating mount namespaces is a relatively rare event compared with querying mounts in a foreign mount namespace this is worth it.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull pid_max namespacing update from Christian Brauner: "The pid_max sysctl is a global value. For a long time the default value has been 65535 and during the pidfd dicussions Linus proposed to bump pid_max by default. Based on this discussion systemd started bumping pid_max to 2^22. So all new systems now run with a very high pid_max limit with some distros having also backported that change. The decision to bump pid_max is obviously correct. It just doesn't make a lot of sense nowadays to enforce such a low pid number. There's sufficient tooling to make selecting specific processes without typing really large pid numbers available. In any case, there are workloads that have expections about how large pid numbers they accept. Either for historical reasons or architectural reasons. One concreate example is the 32-bit version of Android's bionic libc which requires pid numbers less than 65536. There are workloads where it is run in a 32-bit container on a 64-bit kernel. If the host has a pid_max value greater than 65535 the libc will abort thread creation because of size assumptions of pthread_mutex_t. That's a fairly specific use-case however, in general specific workloads that are moved into containers running on a host with a new kernel and a new systemd can run into issues with large pid_max values. Obviously making assumptions about the size of the allocated pid is suboptimal but we have userspace that does it. Of course, giving containers the ability to restrict the number of processes in their respective pid namespace indepent of the global limit through pid_max is something desirable in itself and comes in handy in general. Independent of motivating use-cases the existence of pid namespaces makes this also a good semantical extension and there have been prior proposals pushing in a similar direction. The trick here is to minimize the risk of regressions which I think is doable. The fact that pid namespaces are hierarchical will help us here. What we mostly care about is that when the host sets a low pid_max limit, say (crazy number) 100 that no descendant pid namespace can allocate a higher pid number in its namespace. Since pid allocation is hierarchial this can be ensured by checking each pid allocation against the pid namespace's pid_max limit. This means if the allocation in the descendant pid namespace succeeds, the ancestor pid namespace can reject it. If the ancestor pid namespace has a higher limit than the descendant pid namespace the descendant pid namespace will reject the pid allocation. The ancestor pid namespace will obviously not care about this. All in all this means pid_max continues to enforce a system wide limit on the number of processes but allows pid namespaces sufficient leeway in handling workloads with assumptions about pid values and allows containers to restrict the number of processes in a pid namespace through the pid_max interface" * tag 'kernel-6.14-rc1.pid' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: tests/pid_namespace: add pid_max tests pid: allow pid_max to be set per pid namespace

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull pidfs updates from Christian Brauner: - Rework inode number allocation Recently we received a patchset that aims to enable file handle encoding and decoding via name_to_handle_at(2) and open_by_handle_at(2). A crucical step in the patch series is how to go from inode number to struct pid without leaking information into unprivileged contexts. The issue is that in order to find a struct pid the pid number in the initial pid namespace must be encoded into the file handle via name_to_handle_at(2). This can be used by containers using a separate pid namespace to learn what the pid number of a given process in the initial pid namespace is. While this is a weak information leak it could be used in various exploits and in general is an ugly wart in the design. To solve this problem a new way is needed to lookup a struct pid based on the inode number allocated for that struct pid. The other part is to remove the custom inode number allocation on 32bit systems that is also an ugly wart that should go away. Allocate unique identifiers for struct pid by simply incrementing a 64 bit counter and insert each struct pid into the rbtree so it can be looked up to decode file handles avoiding to leak actual pids across pid namespaces in file handles. On both 64 bit and 32 bit the same 64 bit identifier is used to lookup struct pid in the rbtree. On 64 bit the unique identifier for struct pid simply becomes the inode number. Comparing two pidfds continues to be as simple as comparing inode numbers. On 32 bit the 64 bit number assigned to struct pid is split into two 32 bit numbers. The lower 32 bits are used as the inode number and the upper 32 bits are used as the inode generation number. Whenever a wraparound happens on 32 bit the 64 bit number will be incremented by 2 so inode numbering starts at 2 again. When a wraparound happens on 32 bit multiple pidfds with the same inode number are likely to exist. This isn't a problem since before pidfs pidfds used the anonymous inode meaning all pidfds had the same inode number. On 32 bit sserspace can thus reconstruct the 64 bit identifier by retrieving both the inode number and the inode generation number to compare, or use file handles. This gives the same guarantees on both 32 bit and 64 bit. - Implement file handle support This is based on custom export operation methods which allows pidfs to implement permission checking and opening of pidfs file handles cleanly without hacking around in the core file handle code too much. - Support bind-mounts Allow bind-mounting pidfds. Similar to nsfs let's allow bind-mounts for pidfds. This allows pidfds to be safely recovered and checked for process recycling. Instead of checking d_ops for both nsfs and pidfs we could in a follow-up patch add a flag argument to struct dentry_operations that functions similar to file_operations->fop_flags. * tag 'vfs-6.14-rc1.pidfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: selftests: add pidfd bind-mount tests pidfs: allow bind-mounts pidfs: lookup pid through rbtree selftests/pidfd: add pidfs file handle selftests pidfs: check for valid ioctl commands pidfs: implement file handle support exportfs: add permission method fhandle: pull CAP_DAC_READ_SEARCH check into may_decode_fh() exportfs: add open method fhandle: simplify error handling pseudofs: add support for export_ops pidfs: support FS_IOC_GETVERSION pidfs: remove 32bit inode number handling pidfs: rework inode number allocation

2025-01-12selftests/mm: set allocated memory to non-zero content in cow testRyan Roberts
After commit b1f202060afe ("mm: remap unused subpages to shared zeropage when splitting isolated thp"), cow test cases involving swapping out THPs via madvise(MADV_PAGEOUT) started to be skipped due to the subsequent check via pagemap determining that the memory was not actually swapped out. Logs similar to this were emitted: ... # [RUN] Basic COW after fork() ... with swapped-out, PTE-mapped THP (16 kB) ok 2 # SKIP MADV_PAGEOUT did not work, is swap enabled? # [RUN] Basic COW after fork() ... with single PTE of swapped-out THP (16 kB) ok 3 # SKIP MADV_PAGEOUT did not work, is swap enabled? # [RUN] Basic COW after fork() ... with swapped-out, PTE-mapped THP (32 kB) ok 4 # SKIP MADV_PAGEOUT did not work, is swap enabled? ... The commit in question introduces the behaviour of scanning THPs and if their content is predominantly zero, it splits them and replaces the pages which are wholly zero with the zero page. These cow test cases were getting caught up in this. So let's avoid that by filling the contents of all allocated memory with a non-zero value. With this in place, the tests are passing again.
