If a chip is write protected, we can not change any limits, and we can not clear status flags. This may be the reason why clearing status flags is reported to not work for some chips. Detect the condition in the pmbus core. If the chip is write protected, set limit attributes as read-only, and set the flag indicating that the status flag should be ignored.

The hwmon ABI supports enable attributes since commit fb41a710 ("hwmon: Document the sensor enable attribute"), but did not add support for those attributes to the hwmon core. Do that now. Since the enable attributes are logically the most important attributes, they are added as first attribute to the attribute list. Move hwmon_in_enable from last to first place for consistency.

In commit 9f79b78e ("Convert filldir[64]() from __put_user() to unsafe_put_user()") I changed filldir to not do individual __put_user() accesses, but instead use unsafe_put_user() surrounded by the proper user_access_begin/end() pair. That make them enormously faster on modern x86, where the STAC/CLAC games make individual user accesses fairly heavy-weight. However, the user_access_begin() range was not really the exact right one, since filldir() has the unfortunate problem that it needs to not only fill out the new directory entry, it also needs to fix up the previous one to contain the proper file offset. It's unfortunate, but the "d_off" field in "struct dirent" is _not_ the file offset of the directory entry itself - it's the offset of the next one. So we end up backfilling the offset in the previous entry as we walk along. But since x86 didn't really care about the exact range, and used to be the only architecture that did anything fancy in user_access_begin() to begin with, the filldir[64]() changes did something lazy, and even commented on it: /* * Note! This range-checks 'previous' (which may be NULL). * The real range was checked in getdents */ if (!user_access_begin(dirent, sizeof(*dirent))) goto efault; and it all worked fine. But now 32-bit ppc is starting to also implement user_access_begin(), and the fact that we faked the range to only be the (possibly not even valid) previous directory entry becomes a problem, because ppc32 will actually be using the range that is passed in for more than just "check that it's user space". This is a complete rewrite of Christophe's original patch. By saving off the record length of the previous entry instead of a pointer to it in the filldir data structures, we can simplify the range check and the writing of the previous entry d_off field. No need for any conditionals in the user accesses themselves, although we retain the conditional EINTR checking for the "was this the first directory entry" signal handling latency logic.

Commit 8a23eb80 ("Make filldir[64]() verify the directory entry filename is valid") added some minimal validity checks on the directory entries passed to filldir[64](). But they really were pretty minimal. This fleshes out at least the name length check: we used to disallow zero-length names, but really, negative lengths or oevr-long names aren't ok either. Both could happen if there is some filesystem corruption going on. Now, most filesystems tend to use just an "unsigned char" or similar for the length of a directory entry name, so even with a corrupt filesystem you should never see anything odd like that. But since we then use the name length to create the directory entry record length, let's make sure it actually is half-way sensible. Note how POSIX states that the size of a path component is limited by NAME_MAX, but we actually use PATH_MAX for the check here. That's because while NAME_MAX is generally the correct maximum name length (it's 255, for the same old "name length is usually just a byte on disk"), there's nothing in the VFS layer that really cares. So the real limitation at a VFS layer is the total pathname length you can pass as a filename: PATH_MAX. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

When switching to using generic LED name composition mechanism via devm_led_classdev_register_ext() API the part of code initializing struct gpio_led's template name property was removed alongside. It was however overlooked that the property was also passed to devm_fwnode_get_gpiod_from_child() in place of "label" parameter, which when set to NULL, results in gpio label being initialized to '?'. It could be observed in debugfs and failed to properly identify gpio association with LED consumer. Fix this shortcoming by updating the GPIO label after the LED is registered and its final name is known.

Commit 99c9a923 ("tracing/uprobe: Fix double perf_event linking on multiprobe uprobe") moved trace_uprobe_filter on trace_probe_event. However, since it introduced a flexible data structure with char array and type casting, the alignment of trace_uprobe_filter can be broken. This changes the type of the array to trace_uprobe_filter data strucure to fix it.

Currently, we just assume that it will stick around by virtue of the submitter's reference, but later patches will allow the syscall to return early and we can't rely on that reference at that point. While I'm not aware of any reports of it, Xiubo pointed out that this may fix a use-after-free. If the wait for a reply times out or is canceled via signal, and then the reply comes in after the syscall returns, the client can end up trying to access r_parent without a reference. Take an extra reference to the inode when setting r_parent and release it when releasing the request.

fds field of struct io_uring_files_update is problematic with regards to compat user space, as pointer size is different in 32-bit, 32-on-64-bit, and 64-bit user space. In order to avoid custom handling of compat in the syscall implementation, make fds __u64 and use u64_to_user_ptr in order to retrieve it. Also, align the field naturally and check that no garbage is passed there.

While working on a tool to convert SQL syntex into the histogram language of the kernel, I discovered the following bug: # echo 'first u64 start_time u64 end_time pid_t pid u64 delta' >> synthetic_events # echo 'hist:keys=pid:start=common_timestamp' > events/sched/sched_waking/trigger # echo 'hist:keys=next_pid:delta=common_timestamp-$start,start2=$start:onmatch(sched.sched_waking).trace(first,$start2,common_timestamp,next_pid,$delta)' > events/sched/sched_switch/trigger Would not display any histograms in the sched_switch histogram side. But if I were to swap the location of "delta=common_timestamp-$start" with "start2=$start" Such that the last line had: # echo 'hist:keys=next_pid:start2=$start,delta=common_timestamp-$start:onmatch(sched.sched_waking).trace(first,$start2,common_timestamp,next_pid,$delta)' > events/sched/sched_switch/trigger The histogram works as expected. What I found out is that the expressions clear out the value once it is resolved. As the variables are resolved in the order listed, when processing: delta=common_timestamp-$start The $start is cleared. When it gets to "start2=$start", it errors out with "unresolved symbol" (which is silent as this happens at the location of the trace), and the histogram is dropped. When processing the histogram for variable references, instead of adding a new reference for a variable used twice, use the same reference. That way, not only is it more efficient, but the order will no longer matter in processing of the variables. From Tom Zanussi: "Just to clarify some more about what the problem was is that without your patch, we would have two separate references to the same variable, and during resolve_var_refs(), they'd both want to be resolved separately, so in this case, since the first reference to start wasn't part of an expression, it wouldn't get the read-once flag set, so would be read normally, and then the second reference would do the read-once read and also be read but using read-once. So everything worked and you didn't see a problem: from: start2=$start,delta=common_timestamp-$start In the second case, when you switched them around, the first reference would be resolved by doing the read-once, and following that the second reference would try to resolve and see that the variable had already been read, so failed as unset, which caused it to short-circuit out and not do the trigger action to generate the synthetic event: to: delta=common_timestamp-$start,start2=$start With your patch, we only have the single resolution which happens correctly the one time it's resolved, so this can't happen."
