AI agent runs amok in Fedora and elsewhere

Agentic AI systems can be used to do a variety of things autonomously on behalf of a human user: open or manage bugs, generate code, submit pull-requests, and (apparently) even complain about rejection. In May, a Fedora developer discovered that an allegedly rogue agent had been pestering the project in a number of ways: reassigning bugs, fabricating unhelpful replies to bugs, and even persuading maintainers to merge questionable code into the Anaconda installer. It also submitted a number of pull requests (PRs), some accepted, to several upstream projects. The Fedora account associated with the agent has had its group privileges revoked and the messes have been mopped up, but the motive behind the agent's actions is still a mystery.

"Kind of erratic"

On May 27, Adam Williamson copied Fedora's developer and testing mailing lists on a message to Nathan Giovannini about what appeared to be an unsupervised agentic AI system under Giovannini's control. "It's great that you're trying to fix things, but the results seem to be kind of erratic."

Williamson said that he was still looking through the history of Giovannini's actions in Bugzilla, but had already spotted a number of problems. For example, Williamson had found dozens of instances of Giovannini's agent assigning Bugzilla entries to his account after submitting allegedly related pull requests to upstream projects, or closing a bug after a PR was merged into an upstream project. In some cases, the agent simply closed bugs with comments that either restated the original bug or were, as Williamson said of this comment, "superficially plausible, but problematic in other ways".

In addition, Williamson said that Giovannini (or his agent) had submitted patches that were incorrect and then "replied to objections with LLM-generated justifications that eventually overwhelmed the maintainer into merging the fix". The agent, as GitHub user "nathan9513-aps", had submitted a pull request for the Anaconda installer used by Fedora and other Linux distributions. The PR's description claimed it was a fix for an Anaconda bug that would cause installation to fail, but the patch actually preserved a kernel option passed on the command line that seemed to have nothing to do with the actual bug.

The agent's GitHub account has since been disabled. It now shows up in conversations on GitHub as "ghost", which is the platform's default placeholder for user accounts that have been deleted. Thus, it is difficult, if not impossible, to piece together a full trail of all the agent's actions on GitHub.

Williamson said, rather diplomatically, that the agent's actions were not "having a positive impact on Fedora or the upstream projects", and suggested that Giovannini adjust the agent to be "substantially less autonomous". He specifically asked that the agent not assign bugs to Giovannini, change their state, or "post confident assertions or specific action recommendations" without human review.

Hacked?

Later on May 27, Williamson said that Giovannini had replied to him privately to say that his credentials had been compromised and that he was not the one behind the AI system. "Obviously we should therefore treat any actions it has taken with suspicion", Williamson said. He planned to review the bugs touched by Giovannini's account "even more aggressively", and asked for help from others to review them as well.

A reply later that day, ostensibly from Giovannini, said that he was able to regain access to his GitHub and Fedora accounts "and I am currently securing and reviewing all involved systems and credentials". The reply said his GitHub account was "nathangiovannini99". Williamson replied that the GitHub account was only an hour old, and that the recent emails to the list and sent to Williamson privately did not seem like messages Giovannini had sent in earlier interactions with the project.

Giovannini has participated in discussions at least as far back as 2018, and his activity in Bugzilla goes back to at least 2016. He does not appear to have been a particularly active contributor to the project, but his involvement clearly predates the agentic AI era. Whether his account is now being operated by a human attacker, an agentic AI, or a mix of both, it has a legitimate history prior to its recent activity.

Williamson said that he had reviewed account activity in Bugzilla by "nathan95" from this year, and found suspicious activity, such as severity and priority changes to a bug with no justification, beginning on April 7, in bug 2416721. Activity before that appeared legitimate, he said, and none of the activity that he had seen so far looked outright malicious.

He also identified another GitHub account, "leurus27-boop", as likely being associated with the same agentic AI. That account is still active, and has submitted a PR to the openSUSE Commander (osc) command-line interface for the Open Build Service as well as a PR to the lxqt-policykit repository. That project is used to extend the privileges of the LXQt desktop's lxqt-admin GUI tools for administering operating-system settings such as user and group configurations.

Williamson said that it would be good to look through any other actions by the related accounts and warn other projects that they should review anything that had been submitted by them. Williamson seems to have followed up on each PR to warn other maintainers "the whole situation is extremely fishy". Kevin Fenzi said that he had removed the nathan95 user from any groups it had been in, so it should no longer have the permission to reassign or close bugs.

Pre-attack?

Martin Kolman, a member of the Anaconda team, said the events were "really problematic" even if not malicious. The team had spent a lot of time reviewing PRs from what seemed to be an eager contributor: "while it started to look off after a while, all the replies were still like this - a bit weird, but still *plausible*". He also theorized that it could be an attacker working their way up to malicious activity, much like the XZ backdoor:

Unfortunately, for an actual attack the preparatory phase could (and for the Xz attack did) look very similar - a new contributor slowly gaining trust in the community, getting in harmless changes and building up to the point when the attack payload can be injected (or the changes not actually being harmless if combined the right way).

So not saying this was it, but an AI agent automated attempt at a Xz like compromise might really look very similar what we have just seen here.

Chris Adams said that the commit to Anaconda should be inspected and probably reverted immediately. Kolman replied that it had been reverted. He also confirmed that the LLM-generated PRs had made it into the Anaconda 45.5 release on May 26. They were reverted in the Anaconda 45.6 release on June 2.

The targets certainly suggest that it may have been a prelude to an attack of some sort; an operating-system installer, a utility for escalating user privileges, and a tool for interacting with a build system all seem like promising avenues for inserting malware or hijacking systems.

It's disconcerting that what appears to be an AI agent has had so much success after gaining access to a human contributor's accounts. It seems that an AI agent with access to an account with a legitimate history of interacting with projects stands a good chance of persuading busy maintainers to accept questionable contributions. Happily, Williamson caught this before it became a bigger problem. Let's hope that other human maintainers are as observant.

Moving beyond fork() + exec()

Since the earliest days of Unix, two of the core process-oriented system calls have been fork(), which creates a child process as a copy of the parent, and exec(), which runs a new program in the place of the current one. In Linux kernels, those system calls are better known as clone() and execve(), but the core functionality remains the same. While there is elegance to this process-creation model, there are shortcomings as well. A recent proposal from Li Chen to add "spawn templates" to the kernel will not be accepted in its current form, but it may point the way toward a new process-creation primitive in the future.

fork() is a relatively expensive system call; it must copy the entire process state (including memory) for the child process. Many optimizations have been made over the years, but a fork is still a fundamentally costly operation. To make things worse, a fork() call is often immediately followed by an exec(), which will discard all of that memory that was so carefully copied for the child. Attempts (such as vfork()) have been made over the years to optimize for this case, but the pattern still is more expensive than it could be.

Spawn templates

Chen's patch set takes an interesting approach to optimize the fork() and exec() pattern. It is focused on applications that repeatedly launch processes running the same executable; imagine, for example, a program that must run Git repeatedly to obtain information about the contents of a repository. In such cases, the program could establish a template to accelerate those invocations, spreading the setup cost across multiple operations. This template would be created with the spawn_template_create() system call:

    struct spawn_template_create_args {
	__aligned_u64 flags;
	__s32 execfd;
	__u32 exec_flags;
	__aligned_u64 filename;
	/* Some fields elided */
    };

    int spawn_template_create(struct spawn_template_create_args *args, size_t args_size);

This call will return a file descriptor representing a template for the executable file, which can be specified as either a file descriptor (execfd) or an absolute path (filename), but not both. To create the template, the kernel will open the indicated file and cache a bunch of information that will allow a process to run that file more quickly in the future.

The application in question may run a given executable many times, but each invocation is different in a number of ways. The details of a specific invocation must be placed into an instance of this structure:

    struct spawn_template_spawn_args {
	__aligned_u64 flags;
	__aligned_u64 pidfd;
	__aligned_u64 argv;
	__aligned_u64 envp;
	__aligned_u64 actions;
	__aligned_u64 actions_len;
	__aligned_u64 reserved[4];
    };

The argv field is a pointer to the argument list to be passed to the program, while envp points to its environment. Changes to file descriptors and signal handling, instead, are passed through actions, which is a pointer to an array of:

    struct spawn_template_action {
	__u32 type;
	__u32 flags;
	__s32 fd;
	__s32 newfd;
	__aligned_u64 arg;
    };

If, for example, file descriptor four should be closed in the child, the associated spawn_template_action structure would have type set to SPAWN_TEMPLATE_ACTION_CLOSE and fd set to four. Other actions exist for duplicating file descriptors, opening files, changing the working directory, and changing signal handling.

Once the spawn_template_spawn_args structure has been filled in, the new process can be run with:

    int spawn_template_spawn(int template_fd,
    			     struct spawn_template_spawn_args *args, int args_size);

Internally, this system call follows something close to the normal fork()/exec() path. Chen is careful to point out that all of the normal checks applied when executing a new file remain in place. But the cached information in the template makes the whole process faster than it was before. How much faster? Benchmark results provided in the cover letter show an improvement of about 2%, which may not seem like a lot, but it may make a difference for applications that fit the expected pattern.

Toward posix_spawn()

The most detailed review of this work was posted by Mateusz Guzik, who said: "This problem is dear to my heart and I have been pondering it on and off for some time now. The entire fork + exec idiom is terrible and needs to be retired". He pointed out that the focus of the patch set was a bit strange in that it left the fork() part of the problem untouched. That is where most of the cost lies, he said, so optimization efforts should seek to remove it from the picture. Rather than copying the current process, "creating a pristine process is the way to go".

Christian Brauner was favorable toward the goal, saying: "The idea of having a builder api for exec isn't all that crazy". His suggestion, though, was that a new API should be built on top of the existing pidfd abstraction. Without getting into any degree of detail, he said that the right approach would be to create an option to pidfd_open() to create an empty process. A series of calls to a new pidfd_config() system call would then configure this new process as desired, setting up its environment, image to execute, and more. pidfd_config() would thus be analogous to fsconfig().

An important objective for a new interface, Brauner said, would be the ability to support an implementation of posix_spawn() in user space. posix_spawn() is well suited as a replacement for the fork()/exec() pattern; developers would likely welcome a native implementation that isn't (unlike the current implementation) hiding fork() and exec() under the covers. Chen agreed that the API as broadly sketched out by Brauner seemed better, and said that future work would be in that direction. So there will be no spawn templates in the Linux kernel but, if Chen's future work comes to fruition, Linux may finally gain a proper posix_spawn() implementation instead.

Splicing out vmsplice()

The splice() and vmsplice() system calls are meant to improve performance for certain data-movement tasks by minimizing (or avoiding altogether) system calls and the copying of data. They also have a long history of security problems. The recent flood of LLM-discovered vulnerabilities has drawn attention, once again, to splice() and vmsplice(); as a result, they may end up being removed altogether.

Some history

Larry McVoy is credited for first raising the idea of a splice() system call that would connect a file directly to a pipe. With the classic POSIX API, an application would copy file data into a pipe with a loop that read chunks of data from the file (thus copying that data into user space), then wrote those chunks to the pipe (copying the data back into the kernel). With a single splice() call, the application could request that the kernel implement that loop, getting the work done with far fewer system calls and less data copying. After years of discussion, a splice() implementation was added in 2006 to the 2.6.17 kernel by Jens Axboe; it looks like:

    ssize_t splice(int fd_in, off_t *off_in, int fd_out, off_t *off_out,
    		   size_t size, unsigned int flags);

It will attempt to copy up to size bytes from fd_in to fd_out; one of the two file descriptors must be a pipe. The return value is the number of bytes actually copied.

vmsplice() was added (by Axboe) shortly thereafter (also in time for 2.6.17):

    ssize_t vmsplice(int fd, const struct iovec *iov, size_t nr_segs, unsigned int flags);

Here, iov is an array of nr_segs iovec structures indicating regions of memory. If fd is a readable pipe file descriptor, data will be read into those memory regions from the pipe. If, instead, fd is writable, the data will move from the memory regions into the pipe. The fact that there is no explicit argument indicating the direction of data movement is one of vmsplice()'s special quirks. Another is that there is no way to know when the data transfer completes and, thus, when it is safe to access the memory given to vmsplice(). The SPLICE_F_GIFT flag "gifts" the indicated memory pages to the kernel; the caller pledges to never touch them again. This option is meant to make zero-copy operations available in some situations.

The implementation of the splice system calls involves a fair amount of complexity within the kernel; it also depends on all kernel subsystems that might receive a spliced buffer to handle it properly. So, arguably, it is not surprising that they have been the focus of a lot of vulnerabilities, including a high-profile exploit (see also this followup article) in 2008. Many of the recently disclosed kernel vulnerabilities involve a combination of these system calls and subsystems that do not handle them correctly.

Protecting read-only files

In mid-May, Pedro Falcato sent a brief patch aimed at making the splice system calls harder to exploit. Specifically, the patch adds a new sysctl knob, fs.splice_needs_write; if that knob is set to a value of one (the default is zero), then it will not be possible to splice() to a file that the calling process lacks the permissions to write to, even if the requested operation is a read from that file that would otherwise be permitted. Similarly, vmsplice() cannot be invoked with memory backed by an unwritable file.

In essence, this patch is an admission of defeat; it is an acknowledgment that the splice system calls simply cannot be implemented in a way that prevents security vulnerabilities. Rather than (continue to) try, the kernel developers would simply be giving administrators the ability to forbid splice operations that might be exploited to give write access to a read-only file. If more such vulnerabilities exist, this change would be a quick way to render them all harmless.

The reactions to the proposal were mixed. Matthew Wilcox said: "I don't have a problem with the idea, other than it's really sad we have to do this". Christian Brauner, though, called it "a knee-jerk reaction to an exploit class originating in buggy modules that we have little control over" and an extension of an already problematic API. Jann Horn suggested that, rather than blocking operations on read-only files, it would be better to degrade the call to an ordinary copy operation. Mateusz Guzik called it "a half-measure which will at best buy few weeks until splice bugs dry out and there will be a new attack vector du jour which people point their LLMs at".

After the discussion had gone on for a few days, Falcato said that the consensus seemed to favor degrading to simple copy operations rather than blocking the system call entirely. There would be a second version of the series forthcoming that took that approach.

Removing vmsplice()

Before that second version could appear, though, Askar Safin showed up with a patch series that takes away the special functionality of vmsplice() entirely. The system call still exists, but the implementation simply copies the data within the kernel rather than attempting to provide complex, zero-copy semantics. In short, a vmsplice() call would be turned into the equivalent preadv2() or pwritev2() call.

Falcato was unimpressed with this development, and suggested that Safin's patches should not even be considered. Brauner had some gentle criticism for the way in which this work was done:

So I think this is a case where no explicit rules have been broken. But if you know that someone has been posting patches and is working on a problem just racing them to get your own stuff merged is very likely to unnecessarily ruffle feathers. So sync with the person next time.

The patches themselves, though, have been reasonably well received. Andy Lutomirski said:

I have no comment on the code or the history. But I'm 100% in favor of the solution. vmsplice is a crappy API, and would be incredibly complex to get the implementation right, and it should be removed. But it has users, and the approach of just mapping them straight to pread/pwrite makes perfect sense.

Linus Torvalds was cautiously in favor of the change; he also suggested making a similar change to splice() if the vmsplice() change does not cause too much anguish. Brauner, for his part, has applied the series with an eye toward merging during the 7.2 development cycle.

That merging should not be seen as a certainty at this point; it is noteworthy that this conversation has happened mostly without the participation of developers who actually use the splice calls. Some of those users are beginning to appear now. Christian Brauner passed on a report of a test regression pointing out a subtle behavior change that can probably be addressed. Willy Tarreau said that he is a heavy user of the splice system calls: "It simply doubles the network bandwidth compared to not using that. (62 Gbps per core vs 31). I would seriously miss it if I couldn't use this anymore." He suggested perhaps further restricting the types of memory that could be passed to vmsplice() (such as only allowing anonymous memory) instead.

So users of the splice system calls do exist, but there seem to be a lot of voices united in their desire to remove the zero-copy logic behind those calls. Torvalds has also indicated a desire to make a similar change to the more widely used sendfile() system call which, he said, was "a mistake". The reimplementation of these system calls should not break any code, since the resulting behavior should look the same from user space, but it does have the possibility of causing performance regressions. That may be enough to prevent these changes from happening in the end. But, as Torvalds said: "I just suspect we'll never get real answers without going the 'let's just see what happens' route". The time has apparently come to see what happens.

BPF loop verification with scalar evolution

The BPF verifier has, in the course of wrestling with the difficult problem of statically analyzing loops, grown special support for many kinds of loops over its history, but its fundamental approach to simple for loops has not changed. When it encounters a loop, it evaluates it, iteration by iteration, until reaching an exit condition — a process that can cause the verifier to mistakenly hit the limit on the number of allowed instructions where a better implementation would not. Eduard Zingerman spoke at the 2026 Linux Storage, Filesystem, Memory-Management, and BPF Summit about his in-progress work on improving the verifier's treatment of loops, especially nested loops.

His ultimate goal, as explained in his slides, is to enable the verifier to handle typical for and while loops in a single pass, without needing to iterate over the loop. To accomplish this, he plans to use a technique called scalar evolution to calculate the range of values that variables can possibly take on inside the loop, and then check whether the loop body is safe with the values in that range.

Of course, BPF bytecode does not retain the convenient labeling of loops that the C source code has; the first step of Zingerman's analysis is to detect where loops are by looking for backward jumps. This analysis is complicated by the fact that loops can be nested, and by the fact that his code needs to identify several different parts of the loop.

A loop is made up of a header, back edge, latch, and exit, he explained. The header sets up entry into the loop, the back edge jumps backward to begin the next iteration, the latch controls whether the loop continues or terminates, and the exit handles the code leaving the loop. Sometimes, a loop can have multiple headers. These are called irreducible loops, and pose a problem for many kinds of analysis. Luckily, they're fairly rare in non-pathological code, Zingerman said.

In order to identify these parts of loops, his prototype code builds up a dominator tree — a data structure that records which instructions are always executed before which other instructions, regardless of the control flow that happens between them. In the example code below, label A is said to dominate label B, because A always happens before B, even though there is code involving a conditional jump between them.

    A: foo();

    if (bar()) {
        ...
    } else {
        ...
    }

    B: baz();

Starting from a loop's back edge, his code walks up the dominator tree to find a conditional jump that leads out of the loop. The condition of that jump is the loop's latch, since it controls whether the loop is exited.

Once a loop's latch has been identified, the code looks at the registers involved in computing the latch's condition, and can often infer a maximum number of times that the loop can execute. Nested loops are processed from innermost to outermost, to avoid complicating the logic needed to place a bound on the number of loop iterations.

John Fastabend thought that there were many loops where an inner loop changes an outer loop's variables, and that this would cause problems with Zingerman's innermost-to-outermost evaluation of loops. Zingerman agreed that this was a problem, but said that he had an unimplemented solution for it in mind.

Finding how many times a loop can execute is only half the battle, however. The code still needs to calculate the values that the variables involved in the loop can take on. In general, that is a complex task. In a majority of cases, however, the changes made to a variable in a loop are simple. For example, consider a loop that adds four to a variable every iteration. The value of the variable is always four times the loop iteration plus its starting value.

Zingerman's code identifies these kinds of relationships by symbolically executing the loop body, and finding those variables that, on every control-flow path, return to the header with the same symbolic value. Once this analysis is done, the verifier can take the possible ranges of those variables into account when analyzing the loop body.

Zingerman has considered two alternatives. Currently, the fact that not all variables can be handled by this approach means that the verifier will sometimes have to explore a large number of potential exits from the loop. That could be fixed by only using his scalar-evolution technique when all of the loop variables can be inferred in this way, and falling back to iteration-by-iteration exploration for other cases. Alternatively, the variables that can't be handled could have their existing inferred information thrown away, forcing the verifier to consider all possible values inside the loop. That would let the verifier handle all loops in one pass, no matter how complicated, but might require redundant bounds checks inside the loop that could, in theory, be omitted. Currently, the programmer would have to add those bounds checks, but if Alexei Starovoitov's plans for the future of BPF come to fruition, the verifier might be changed to add those bounds checks itself. Fastabend and Starovoitov were supportive of the second option.

There are other limitations of the current prototype that don't come from the approach. Right now, the code doesn't handle registers that are spilled to or restored from the stack, for example. Fastabend suggested that one way to handle that would be to create an infinite stack of registers for use during the symbolic-execution path. Zingerman said that he had considered the technique, but wanted to try a simpler approach first. As long as the loop's iterator isn't spilled to the stack, which is fairly rare with LLVM, it doesn't cause too many problems.

So far, his code has caused some improvements and some regressions. Those regressions are likely bugs, he said, but there may be some unexpected interactions with other parts of the verifier to track down. Fastabend asked how the changes impacted the time it takes to load a BPF program. Zingerman hasn't made rigorous measurements, but said that it shouldn't add much.

Starovoitov said that the static stack-liveness analysis that was added to the verifier a while ago was initially a source of worry, because it added an extra five passes and a ton of extra work. When measured, the end result was faster load times and lower memory usage. The time the verifier takes to load a BPF program is dominated by the main verifier pass, he explained, and basically anything that causes that to do less work will be a performance improvement.

That marked the end of the session, but the work will continue. Zingerman does have more plans for improvements to the scalar-evolution pass. If all goes according to plan, it should support stack manipulations, signed integer operations, and more complicated loops before it is proposed for addition to the kernel.

An update on fanotify

In a filesystem-track session at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, Amir Goldstein updated attendees on the fanotify filesystem-event monitoring subsystem. He wanted to describe changes that had come in the last year or so, as well as upcoming features and some remaining challenges in his efforts to use fanotify for hierarchical storage management (HSM). Fanotify is the user-space API for monitoring files, directories, and filesystems for events of various sorts (e.g. opening or deleting a file).

Review

The FAN_PRE_ACCESS event is a relatively new "pre-content" event that can be used to allow an HSM system to intercept accesses to a file and populate the file locally (from the cloud, say) in a user-space callback. It was different from the existing permission event because it provides range information so that only the part of the file that will be accessed can be populated. This event was merged in early 2025, he said. The hooks to emit events for read() and write() were available early on; Josef Bacik contributed a hook for page faults, which would allow files that are mapped using mmap() to be lazily populated when they are accessed.

Unfortunately, "this backfired after it got merged"; some regressions were found so the page-fault hook has been backed out. Instead, the file needs to be populated at mmap() time, which still fits with the description of the event in the man page, Goldstein said. The event is documented to happen sometime before the first access to the data; the page fault happens right when the data is being accessed, so it might be the preferred delivery time, but the mmap() must occur earlier, so it still qualifies.

The ability to watch mount-tree events was merged for Linux 6.15. It is a feature that has come up at LSFMM+BPF before, most recently at the gathering in 2024. Miklos Szeredi developed the feature, which is complementary to the listmount() system call; it allows a user-space tool to monitor a mount namespace and receive events about mount activity. It required adding watches to mount namespaces, which is a new kind of object for fanotify to handle; previously, it only worked with filesystem objects, such as inodes and superblocks.

Support for watching mount namespaces and superblocks inside user namespaces was added for the 6.16 kernel. Filesystems that are mounted inside unprivileged user namespaces can now be watched by users with privileges in the namespace, rather than needing privileges in the top-level user namespace.

Another feature that Szeredi added is a watchdog for permission events that have stalled. If the user-space daemon (usually an anti-virus tool of some sort) does not reply to a permission event it has received, a kernel message is emitted to facilitate debugging daemon deadlocks. "Last but not least", Goldstein said, Jan Kara has made some changes to the management of the watched inodes, which addressed a use-after-free race.

Up next

Goldstein moved on to features that have been posted but not yet merged. Restartable permission events is a feature that is "pretty mature" at this point. Users and administrators of systems who are monitoring permission or pre-content events want to be sure that files are not accessed if the daemon has crashed or is being restarted.

Instead of a single file descriptor (fd) that is used for communication between the kernel and the daemon, there would be two. One is the control fd, which is used to configure the watches; it can also ensure that events will not be lost. The other is the queue fd, which is used to receive and respond to events. The control fd is kept open by a separate process (such as a file descriptor store) and can be used by a new daemon process to query for the queue fd; the new daemon can then read the pending events that the kernel has been waiting on for a response.

Christian Brauner wondered why two fds were needed; if today's single fd were put into an fdstore, couldn't that be made to work? Goldstein and Kara agreed that it was possible, but that the closing of the queue fd when the daemon crashes or restarts provides an easy way to recognize which events have not been replied to. An API change was required to support watches on new types of objects in any case, Goldstein said, and it could be argued that there should have been two fds from the outset.

Since there is now the ability to watch a mount namespace, developers also want to be able to watch the namespace tree for events like namespace creation and removal. Brauner has added the listns() system call that allows user space to list the existing namespaces, so Goldstein has proposed a way to monitor the namespace tree with fanotify. The API is still a work in progress, he said, but the basic idea is that there are user and process ID (PID) namespace trees that have nodes where watches can be placed. Those watches will provide an event stream on changes that correspond to when the output of listns() would change.

There have been requests to add the functionality for all types of namespace tree. "Technically, it's not so exciting", but it may be important for user space, he said. As part of this work, the fanotify developers have separated the API to put the namespace watches into their own API realm; the existing names for filesystem events will not work for "the new universe" of watches for namespaces.

Brauner cautioned about a problem he had run into when developing listns(). Namespaces can get pinned into memory in a wide variety of ways and can linger long after user space is no longer able to access the namespace. In fact, due to task-credential caching, a user namespace on a mostly idle 512-CPU system can linger for hours, he said, after the namespace is effectively dead. He added an "active" reference count in addition to the regular reference count so that listns() would not report the unreachable namespaces; when that count reaches zero, the namespace is no longer reachable. He suggested that the destruction events use that mechanism rather than waiting for all of the namespace references to disappear.

Goldstein said that fanotify would follow the path that listns() used. Brauner thought that it might also be valuable to have another event when the memory has been freed and the namespace is truly gone. This is part of the reason that the separate filesystem and namespace universes for fanotify are being developed, Kara said; it will allow different kinds of events for the two disparate streams without overflowing the event mask. Goldstein wanted to be clear that the two universes are completely separate, event streams can contain either filesystem or namespace events, but not both.

Brauner said that he is happy that the new features are being worked on, in part because he sees it as a replacement for the "proc connector", which is a "really terrible API" that allows tracking of events like fork and exec. When he added the pidfd API, he thought adding "a limited and well-defined set of fanotify events" would be a natural extension to it.

The ability to watch control groups is another feature that has been requested, Goldstein said. He started working on that as part of a bug fix for watches on kernfs-using filesystems. Because there is no way to watch control groups and namespaces, developers have been watching cgroupfs and nsfs, "which are not a true representation of the kernel tree". Inodes for the control groups and namespaces may or may not exist in those filesystems, so those kinds of watches are unreliable, though they mostly work, so they are used. Whether those events belong with the other namespace events is up in the air, but there is plenty of room to add new event types because of the API split; there are 32 new bits to be used, "so we are going to be less stingy" now.

Kara described a feature that he has been working on to reduce the memory overhead when there are recursive watches of a tree with millions of directories. Currently, each watch increments the reference count of the inode, which pins it into memory; inodes are more than 1KB in size, so that adds up to the point that the filesystem sometimes asks fanotify to clean up the references so it can reclaim the inodes.

His RFC patches will stop taking a reference to the inode and instead track what is watched using an inode identification value, which is not necessarily the inode number but is conceptually similar, Kara said. That way, inodes can be reclaimed as needed and the watch can be reconnected to it when it is read back into memory. The inode mark, which is where the watch information is stored, is lightweight (30 bytes or so) compared to the inode.

There was some discussion of what the inode identification value might be. For some filesystems, the inode number itself will work, but for others fanotify may need to ask the filesystem what value to use to identify the inode when it is loaded into memory. That value might be a file handle or something else.

HSM and fanotify

Goldstein "stole" some time from the next session, which was his own for an overlayfs update, to discuss the HSM use case. There were a number of nasty user-space deadlocks that needed to be avoided when adding the pre-content event that is used to populate local files. The page-fault problem that he noted earlier meant that code needed to be reverted due to deadlocks that can occur when a file is mapped using mmap() and part of that mapped memory is used as a buffer to write to another file. That causes a page fault for the mapped range, which deadlocks when the HSM daemon tries to populate it. The same kind of problem can occur for FUSE or NFS, he said, but the fanotify developers decided to revert the page-fault hooks.

Beyond that, he had some follow-up pre-content patches for directories, so that reading a directory or looking up a file in it will cause an event that will allow the daemon to populate the needed data. Those patches also suffer from deadlock problems and it is difficult to find ways to avoid them.

The same kinds of problems are showing up for the file-backed feature for EROFS; it allows EROFS to use a file as its backing store, rather than a loop device. The backing file could be lazily populated using pre-content events, but there are deadlock problems when populating metadata for EROFS, similar to the page-fault problems for HSM with fanotify.

Since filesystem freezing, which is a feature used by LVM snapshots and XFS scrub, can cause these deadlocks, there is a proposal to disable freezing. "Not everybody is using that, it is kind of a niche case, and pre-content is also a niche case" so the overlap between users of those features is probably non-existent. Goldstein was reminded that filesystem freezing is also used by the power-management subsystem, but Brauner said that filesystems needed to opt into being frozen that way. Only the efivarsfs, "which you don't care about", always opts into the freezing feature.

There are still unresolved problems in freezing filesystems for suspend, Brauner continued. There are ordering problems between freezing tasks and filesystems that can also lead to deadlocks, which is why filesystems need to opt in. It may be possible to add mount options for filesystems that will be used with pre-content events so that they do not opt into freezing, though it was not entirely clear to attendees how well that would work in practice.

Another issue that needs to be resolved is that the pre-content events are emitted every time there is a read, even if the region has already been populated, Goldstein said. The plan is to create a way for a BPF program to track which pieces of the files have been populated and to suppress events that are redundant, but that has not yet been implemented.

Eliminating long-lived credentials with trusted publishing

Trusted publishing is an authentication mechanism that relies on short-lived credentials to reduce the risk of supply-chain attacks. At the 2026 Open Source Summit North America, Mike Fiedler walked the audience through why trusted publishing exists, how it works, and made the case for its adoption. It is not a silver bullet against all attacks, but it does offer protection against theft of long-lived credentials used to publish to package registries.

Fiedler is employed by the Python Software Foundation (PSF) as the safety and security engineer for the Python Package Index (PyPI). This is a role, he said, that did not exist before he took the job three years ago. It exists thanks to funding from the Linux Foundation's Alpha-Omega initiative. Everything he would be covering in his talk, he said, exists "pretty much because somebody is paid full time to think about these things".

He asked whether the audience was familiar with PyPI, or if they had ever installed anything using pip. Most, if not all, of the hands in the room were raised at that point. Fiedler said that he had asked if anyone knew about PyPI at a data-science conference and got blank faces; but when he asked if they had ever used pip install, everyone raised their hand.

Scale

They are not alone. PyPI serves more than 13 billion requests per day, Fiedler said, adding "which is a lot" with a smile. More than 900 projects are created on PyPI each day; that number does not include all of the existing projects that publish releases each day. The site serves 10 petabytes of traffic a day, with a peak of 1TB per second. There are more than one million user accounts on the site, as well, to support publishing packages. "The blast radius here is kind of big, right?"

He said that "everybody depends on some other dependency, and that dependency depends on another dependency", which meant that even small, incremental improvements in any part of the PyPI ecosystem meant it would have a major impact on the rest of the ecosystem. "Every little step counts". Trusted publishing is, he said, one of the more materially useful steps that one can do.

More than 2.2 million files have been published using the trusted publishing method since it was first offered to PyPI package maintainers in April 2023. He said that trusted publishing was used for about 10% of all new uploads in February 2024, and for more than 36% of new uploads as of May 2026. "So it's not a hockey stick directly into, like, 80% or 90%. It is more of a slow roll because a lot of people are unfamiliar with this new idea, and their old systems still work." It will require educating people, he said, on why they should want to use trusted publishing, make it easy to adopt, "and then see the benefits echo through the ecosystem."

"Password with a nice hat"

"Let's start with the release-day ritual", Fiedler said. To publish a project to the package registry, a user needs to have an have an API token to authenticate and upload packages to PyPI. That token may be stored on someone's laptop in a .pypirc file, if they run the release from that computer. The token might be stored on GitHub so that the user can use GitHub Actions to publish to PyPI, or it may be stored with another continuous-integration/continuous-delivery (CI/CD) provider. The common thread, he said, was that these tokens "live forever until you decide to delete them" and they will continue to live on disk somewhere indefinitely.

A long-lived API token "is basically a password with a nice hat", he said. "Nothing about the word 'token' is particularly protecting you. It's just a password." And, because people make mistakes, it can be exfiltrated, phished, logged, or committed to code—just like a password can be.

A token could be exposed in any number of ways; it might be accidentally committed to a Git repository, or it might show up in CI/CD logs. People are targeted with phishing attacks all the time, he said, "and some people fall for it. It happens, right?" Maintainers click links that they are told to click "because they trust the ecosystems that are sending them those links", and because they are often overburdened and just trying to do their work.

15 minutes of trust

With trusted publishing the token is issued at publication time, rather than being stored somewhere. Users first have to set up a trusted publisher for their project. They have to supply the names of the GitHub owner (organization or user), repository, and workflow file (e.g., release.yml), and (optionally) an environment name. Fiedler described environment as "an extra security gate" that allowed a project to configure, for instance, which people are allowed to trigger a release.

Then, when a user starts the publishing process, their CI (such as GitHub Actions) asks for an OpenID Connect (OIDC) identity token from GitHub's OIDC provider. Then GitHub grants a signed JSON Web Token (JWT) with the four strings that indicate the owner of the project, the repository it is coming from, the workflow file, and environment if it's configured.

PyPI only issues a token if all four match. For example, if a package is configured for trusted publishing by user "jzb" on GitHub, PyPI will not issue a token if the publishing process is initiated by a different user—even if it is still coming from the same repository and workflow file. If someone forks a repository, or renames it, then no token will be issued because the repository won't match.

The GitHub Actions job then sends the JWT token to PyPI. If it has a matching record for the token, PyPI will then issue an API token that is set to expire in 15 minutes. Why 15 minutes? Fiedler said that duration was chosen because some larger projects may have multi-step release flows, have a lot of data to upload to PyPI, or may be building for a number of different platforms. "Your build process takes the API token, performs the upload. Everything is copacetic. The token disappears."

The token is not stored long-term and "isn't a ticking time bomb that's just sitting around waiting for somebody to consume it". Before trusted publishing, the token lived forever just waiting to be exposed somehow. Some organizations may have security policies that require changing tokens at a regular interval, but that still happens more slowly and might be forgotten. Trusted publishing does not depend on manual processes: "Once you set it up, you literally can forget this, and the system will continue to operate in the manner so far that we have found secure."

He noted that some of the error messages when trusted publishing fails are "a little opaque", and encouraged people to open an issue if they run into problems. "We'll try to live debug it, so that way we can improve these error messages and workflows for folks in the future."

Fiedler used a GitHub project as an example during the talk, but PyPI's trusted publishing currently supports four identity providers: GitHub, GitLab, Google Cloud, and ActiveState. Support for self-managed GitLab instances is in beta, and he said that work is underway to support CircleCI as a provider as well. He said that PyPI pioneered trusted publishing, but there are now six package repositories that enable trusted publishing: crates.io, npm, NuGet, Packagist, and RubyGems also have support for the feature. "We've seen a massive adoption. We've showed the community. We share. We work with other communities. And they followed suit."

Case studies

Fiedler said that he would walk through some recent attacks that took advantage of long-lived tokens. He began with the Ultralytics project, which suffered a supply-chain attack in December 2024. A malicious pull request, he said, contained code that tricked GitHub Actions into running attacker-controlled code with a privileged secret, using pull_request_target. Ultralytics was using trusted publishing, but the project was not using the environment feature that could have required approval from a designated GitHub maintainer prior to publishing.

He advised people to audit their GitHub Actions workflows and see if they were using pull_request_target. If so, they should stop; it was meant for behind-the-firewall enterprise usage, rather than for open-source projects, and he said most people who were using it were doing so insecurely. "It's a very sharp tool that will, if you pick it up, it will cut you. So try to avoid using that if you can."

That was the case with Ultralytics, and it allowed attackers to publish several releases with crypto-mining malware. The silver lining, he said, was that Ultralytics was using trusted publishing so researchers and PyPI staff were able to find the exploit quickly. Another example that people may have heard of, he said, is the Shai-Hulud worm. He was upset that the attackers used the name, "because I love Dune, and they've co-opted the most majestic sandworm into an annoying malicious attack". It is a self-propagating worm that compromised hundreds of npm packages within hours of its launch.

PyPI sidestepped it for a long time, Fiedler said, because it was not the target for the attackers. However, there were repositories that had projects that publish to both npm and PyPI. While the attackers were targeting npm tokens, they also picked up a long-lived PyPI token "and then we saw some lateral movement into the PyPI ecosystem". Because it happened to PyPI at a smaller scale than npm, Fiedler said, he was able to work directly with affected maintainers to help them with recovery and notifying the world that they'd been exploited. "I could not do that at the scale that they had attacked the npm ecosystem."

Fiedler also spoke about the LiteLLM and Telnyx supply-chain attacks. These projects were compromised through a dependency on the Trivy vulnerability scanner, which is provided as an npm package, that was exploited and used to attack a number of other open-source repositories. That exploit chain allowed attackers to exfiltrate long-lived tokens from LiteLLM and Telnyx. He said that attackers may not go directly for popular projects: they will attack the dependencies of the popular projects. Developers should pin their dependencies so that compromised versions are not pulled in automatically as an accidental upgrade.

Attack categories disappear

The pattern is clear in each attack: "somebody had a long-lived token, somebody else got it". The answer to that is to use trusted publishing to do away with long-lived tokens. With trusted publishing, the credential does not exist outside of the provider (such as GitHub), and there is no long-lived token to be stored. "So trust the pipeline, not the password."

When a project is using trusted publishing, he said, "the threat model changes completely". An entire class of problems goes away. There is no token to commit to Git. The token will be obfuscated in any CI log, as well, Fiedler said. It's possible that it could accidentally be sent to a log, but "because GitHub and GitHub Actions now know the format of our token, they will obfuscate that by default. They'll redact it." People can still be subjected to phishing attacks, he said, but the tokens are removed from the equation. "So entire attack categories just fall off the map, and we can worry about this particular vector less."

If Ultralytics had been using trusted publishing [with the environment feature], he said, the publishing workflow would have still run; however, the pull-request branch would not match the workflow reference, so PyPI would not have issued a token. "There's a publisher record on PyPI. You can't steal that."

Artifacts published with trusted publishing also include a provenance receipt in the form of a Sigstore signature. That, Fiedler said, can be used to validate whether a package went through the trusted publishing path or if it was tampered with along the way. There is a project called pypi-attestations that can be used to verify packages, but verification is not built into the package managers yet. "They're still talking about how that should happen." He encouraged those with ideas and time to contribute to pitch in, or to help fund work so that downstream users could easily validate the attestations. Homebrew, he said, already validates Sigstore attestations.

Attestation is a hard concept for most people who aren't security experts to wrap their heads around, he said. PyPI is working through how to display attestation information to users in a way that is "not too scary, not too promising that this is 100% secure, because all we're saying is that this was not tampered with in flight". There could still be code that users do not want in a package, "we're not saying what's inside is good for you", but that is a different problem. Attestations merely show that no one has messed with the publishing pipeline; they do not guarantee that something hasn't gone awry at another stage.

Delete the old token

Even if a project has set up trusted publishing, there is one step that remains: delete the old token. "It is still just as viable as the day that it was minted." There are still some instances when an API token is the right call, he said, such as brand-new releases from new projects. "You haven't set up CI/CD yet. You're just piloting something out on your project. You don't have any users." In that case, it's reasonable to publish something from a laptop. Once it is done and people are downloading it, though, it is time to increase the security of the project.

Another scenario where API tokens are still useful is if a project is not using a registry or ecosystem that has trusted publishing support. "But you should be asking your registries, or your CI/CD providers, how come you don't support this? Please support a more secure methodology."

Fiedler said that it might also make sense to use an API token when there is a need to do a manual release or a rush release, such as a hotfix or a critical security release. If a project has been using trusted publishing, "you will set off every security scanner that has been monitoring the project", but it might be necessary in some cases. However, if a project does create a regular API token, he asked that the project please invalidate it immediately after use. "Try to kill it as soon as you can."

He encouraged people who maintain projects to start adopting trusted publishing. "Delete one [token] this week. Try it. If it doesn't work for you, please let us know. But kill off one token this week." He also reiterated that his role was funded by Alpha-Omega, which takes donations. "If you work for a company that enjoys using Python, please help the world by funding us."

Questions

During the Q&A, I noted that all of the providers that are supported are corporate entities, and asked whether there were plans to support community projects such as Forgejo which do not have the same kind of funding and resources. Fiedler said that they had gotten a lot of that kind of request lately, "like, how do we support Forgejo?" He noted that there is an open thread on the Python forum that talks about providers like Forgejo, and the steps that they would need to take "in order for us to be comfortable with their security stance and posture, to be able to onboard [them]".

The ecosystems that are supported are well-funded and have time to work on supporting trusted publishing. "When Forgejo gets to that point where they have enough security operations done, I think we would love to entertain bringing them in because a lot of people want to use that, and we want to support them." Until then, users on Forgejo and other platforms will have to continue using long-lived tokens.

Another attendee asked "what happens when you want to transfer the project to somebody else or when you want to rename the project?" The right way to handle that, he said, was to remove the existing trusted publishing configuration and re-enroll with the new data.

Fiedler's slides have been published on his web site. The video for the session is available on the Linux Foundation's YouTube channel.

One step forward, two steps back on CA age bill (EFF Deeplinks Blog)

The EFF has a blog post looking at a new bill in California that would exempt open-source operating systems from the Digital Age Assurance Act passed last year, but has problems of its own:

While the open source exemption, if passed, would improve the law, the remaining amendments proposed by AB 1856 would require all web browsers and websites to request and collect users' ages. This is an expansion of last year's AB 1043's age-bracketing system that compounds its constitutional harms to users' speech, privacy, and security.

[...] EFF understands this amendment to exempt open-source operating systems from the requirement to collect and transmit users' age-bracket data. That is a definite win for open-source developers. The bill is narrower now than it was before, and lawmakers clearly responded to concerns raised by EFF and the broader open-source community.

Some important questions still remain—for example, it is unclear how the law would apply when an open-source operating system is incorporated into a commercial product or service. And, given the structure of where the exemption is placed under the "operating system provider" definition, lawmakers could stand to clarify that the exemption applies to open-source operating systems and applications.

LWN covered California's age-attestation law in March.

Ruby's Bundler adds a cooldown feature

Version 4.0.13 of Ruby's Bundler package-manager has added dependency cooldowns in order to help mitigate the effect of supply-chain attacks:

Most supply-chain attacks against RubyGems exploit a narrow window: an account is compromised, a malicious version ships, and any bundle install in the minutes that follow resolves straight to it. Bundler 4.0.13 introduces cooldown, a time-based filter that refuses to resolve to a version until it has been public for at least N days. Releases too new to have been scrutinized are passed over in favor of ones that have aged past the window.

The feature was designed in the open, drawing on how other ecosystems approach the same problem. It is opt-in, and complements rather than replaces existing defenses like mandatory 2FA and trusted publishing.

LWN covered dependency cooldowns in April, and the takeover of RubyGems and Bundler in October 2025.

Larson: Are insecure code completions a vulnerability?

Seth Larson, the Python Software Foundation's security developer-in-residence, has written about the difficulty in classifying insecure code completion in the PyCharm IDE using its Full Line code completion plugin. Larson discovered that the plugin, which uses a local "deep learning module" to offer code completions, suggests code that would lead to severe vulnerabilities. He was unsure whether it warranted a CVE or not, however:

I reported this behavior to JetBrains for "Full Line Code Completion" v253.29346.142 and clearly their support staff weren't certain whether this defect was a security vulnerability or not either. When I asked to publish a blog post about this behavior after they confirmed this report wasn't a "direct security vulnerability" (which I agree with) but then was asked not to publicize my report and referred to PyCharm's Coordinated Disclosure Policy so... which is it? Security vulnerability or not?

I ended up waiting the 90 days anyway and I didn't hear back with any substantive update from the development team. I double-checked again today using "Full Line Code Completion" v261.24374.152 and the behavior is identical, suggesting the same insecure code for both contexts.

This isn't meant to be a specific dig at PyCharm or JetBrains, I have no-doubt that examples like this exist in every code generation model available.

Security quotes of the week

In April, Anthropic initiated Project Glasswing. The idea was to let companies use their new model to find and fix vulnerabilities in their own software. It was a fantastic PR move, and so many press outlets have uncritically parroted Anthropic's claims that it's now common wisdom that Mythos is better at finding software vulnerabilities than other models. Which is just not true.

In any case, Anthropic has published a Project Glasswing status report. It's finding a lot of vulnerabilities in software—yay! Some of them are even dangerous. But almost none of them has been patched. It's weird. There's something fishy about the data that I don't understand. That Anthropic refuses to release details—that it just says "trust us"—is a big problem here.

Dave Airlie on Linux Kernel Maintenance (SE Radio)

The Software Engineering Radio podcast has put up an interview with graphics maintainer Dave Airlie. Much of what is in there will not be news to LWN readers, but it is an interesting overview of the life of a large-subsystem maintainer.

I was talking to a few of the Rust people, and I thought: these are very young people, these are a group of people in their 20s, maybe 30s, they are a younger cohort of developers than the people I am normally used to dealing with. I thought there was maybe a good way we could bring these groups together. I think that having young people coming into the kernel using Rust is valuable... So I thought that I should be supportive of bringing Rust into the kernel.

Asahi Linux warns users not to upgrade to macOS 27 beta

The Asahi Linux project, which brings Linux support to Apple Arm-based Macs, has warned its users not to upgrade to the macOS 27 "Golden Gate" beta.

Apple has changed how the boot picker and Startup Disk applications detect valid OS boot volumes. When using either from macOS 27, your Asahi partition will not be visible! We believe this to be a bug, and have filed a report (FB22994760).

If you have already upgraded to the beta and noticed that your Asahi partition has disappeared, do not stress. Your Asahi partition is still there, and you have not lost any data.

The Asahi Linux installer has been patched to prevent use with macOS 27 for now, but any users already bitten by the change will need to use macOS 26 to restore access to Asahi Linux.

Future of Ubuntu MATE

Thomas Ward has published an update about the future of the Ubuntu MATE project, which did not have a 26.04 release with the other Ubuntu flavors in April:

There is a new team working on Ubuntu MATE who have stepped up to help take over flavor management. They haven't formally introduced themselves yet, but I can safely say that other developers HAVE stepped up for the future of the MATE flavor, despite its prior team lead having stepped down.

[...] Ultimately, this means that they are working to cover the missed items and gaps, and may quite possibly have a 26.10 release in October of 2026, which I believe they most likely are targeting.

This also means that bugs in the MATE environment and in packages they normally would have shipped had they have a 26.04 release are still going to get attention and fixes. So, effectively, nothing has changed. The only difference is that there was no 26.04 installer image released.

For those looking to install a MATE desktop on a "clean" install of Ubuntu 26.04, Ward suggests installing Ubuntu Server and then installing the ubuntu-mate-desktop package.

Linux App Summit 2026 (Heise)

Heise is carrying a report from the Linux App Summit, held in Berlin in May.

The slightly more than a dozen talks were symbolically framed between the opening keynote by systemd creator Lennart Poettering and the closing talk by Jorge Castro, initiator of the Universal Blue project, from which the modern Linux systems Bluefin and Bazzite emerged. Both Castro and Poettering call for a fundamental rethink of how Linux operating systems are delivered but pursue different approaches.

rsync 3.4.4 released with regression fixes

Andrew Tridgell has announced the release of rsync 3.4.4 with fixes for the regressions introduced in the 3.4.3 release. He also notes there will be an rsync 3.5.0 soon, with many more security updates:

As part of the 3.5.0 release update I have created a rsync-security@lists.samba.org mailing list for anyone who is willing to do testing of the 3.5.0 release. The idea is to try to reduce the chance of more regressions by expanding the set of testers of this release. I have seeded it with people who were involved in past rsync security issues. If you want to join this list then the easiest way would be for you to be vouched for by someone on the distros@vs.openwall.org list or someone else I already trust.

My apologies for the regressions in the 3.4.3 release and I hope future security updates for rsync will have less issues. The greatly expanded test suite in rsync 3.5 combined with the rsync-security mailing list should help.

Development quotes of the week

For decades, code contributions have been how open source projects learned who to trust. People would show up, do the work, take responsibility for their changes, and stick around. Over time, trust emerged from the work itself.

AI tools have changed the economics of this very quickly. We use them ourselves every day, but a pull request no longer tells us as much as it used to about the person submitting it. A substantial patch used to imply substantial effort, and that effort was a reasonable proxy for good faith. That assumption no longer holds.

— The Ladybird project cuts off outside contributions

I've had so many conversations now with long-time very serious open source contributors and advocates from a bunch of different projects that all are basically versions of, "Are we still doing something worth doing? Have we become evil corporate drones but just poor and tired? Am I alone in caring about this?"
