2023-07-27staging: Explicitly include correct DT includesRob Herring14-17/+7
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-07-23kbuild: rust: avoid creating temporary filesMiguel Ojeda2-2/+9
`rustc` outputs by default the temporary files (i.e. the ones saved by `-Csave-temps`, such as `*.rcgu*` files) in the current working directory when `-o` and `--out-dir` are not given (even if `--emit=x=path` is given, i.e. it does not use those for temporaries). Since out-of-tree modules are compiled from the `linux` tree, `rustc` then tries to create them there, which may not be accessible. Thus pass `--out-dir` explicitly, even if it is just for the temporary files. Similarly, do so for Rust host programs too.

git://git.samba.org/sfrench/cifs-2.6 Pull smb client fix from Steve French: "Add minor debugging improvement. The change improves ability to read a network trace to debug problems on encrypted connections which are very common (e.g. using wireshark or tcpdump). That works today with tools like 'smbinfo keys /mnt/file' but requires passing in a filename on the mount (see e.g. [1]), but it often makes more sense to just pass in the mount point path (ie a directory not a filename). So this fix was needed to debug some types of problems (an obvious example is on an encrypted connection failing operations on an empty share or with no files in the root of the directory) - so you can simply pass in the 'smbinfo keys <mntpoint>' and get the information that wireshark needs" Link: https://wiki.samba.org/index.php/Wireshark_Decryption [1] * tag '6.5-rc2-smb3-client-fixes-ver2' of git://git.samba.org/sfrench/cifs-2.6: cifs: update internal module version number for cifs.ko cifs: allow dumping keys for directories too

2023-07-23tracing/histograms: Return an error if we fail to add histogram to hist_vars ↵Mohamed Khalfella1-1/+2
list Commit 6018b585e8c6 ("tracing/histograms: Add histograms to hist_vars if they have referenced variables") added a check to fail histogram creation if save_hist_vars() failed to add histogram to hist_vars list. But the commit failed to set ret to failed return code before jumping to unregister histogram, fix it.

2023-07-23ring-buffer: Do not swap cpu_buffer during resize processChen Lin2-2/+15
When ring_buffer_swap_cpu was called during resize process, the cpu buffer was swapped in the middle, resulting in incorrect state. Continuing to run in the wrong state will result in oops. This issue can be easily reproduced using the following two scripts: /tmp # cat test1.sh //#! /bin/sh for i in `seq 0 100000` do echo 2000 > /sys/kernel/debug/tracing/buffer_size_kb sleep 0.5 echo 5000 > /sys/kernel/debug/tracing/buffer_size_kb sleep 0.5 done /tmp # cat test2.sh //#! /bin/sh for i in `seq 0 100000` do echo irqsoff > /sys/kernel/debug/tracing/current_tracer sleep 1 echo nop > /sys/kernel/debug/tracing/current_tracer sleep 1 done /tmp # ./test1.sh & /tmp # ./test2.sh & A typical oops log is as follows, sometimes with other different oops logs.
