git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c component probing support from Wolfram Sang: "Add OF component probing. Some devices are designed and manufactured with some components having multiple drop-in replacement options. These components are often connected to the mainboard via ribbon cables, having the same signals and pin assignments across all options. These may include the display panel and touchscreen on laptops and tablets, and the trackpad on laptops. Sometimes which component option is used in a particular device can be detected by some firmware provided identifier, other times that information is not available, and the kernel has to try to probe each device. Instead of a delicate dance between drivers and device tree quirks, this change introduces a simple I2C component probe function. For a given class of devices on the same I2C bus, it will go through all of them, doing a simple I2C read transfer and see which one of them responds. It will then enable the device that responds" * tag 'i2c-for-6.13-rc1-part3' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: MAINTAINERS: fix typo in I2C OF COMPONENT PROBER of: base: Document prefix argument for of_get_next_child_with_prefix() i2c: Fix whitespace style issue arm64: dts: mediatek: mt8173-elm-hana: Mark touchscreens and trackpads as fail platform/chrome: Introduce device tree hardware prober i2c: of-prober: Add GPIO support to simple helpers i2c: of-prober: Add simple helpers for regulator support i2c: Introduce OF component probe function of: base: Add for_each_child_of_node_with_prefix() of: dynamic: Add of_changeset_update_prop_string

These are functions that are used by trace_printk() that allows to quickly save the format and arguments into the ring buffer without the expensive processing of converting numbers to ASCII. Then on output, at a much later time, the ring buffer is read and the string processing occurs then. The bprintf() was added for consistency but was never used.

2024-12-01strscpy: write destination buffer only onceLinus Torvalds
The point behind strscpy() was to once and for all avoid all the problems with 'strncpy()' and later broken "fixed" versions like strlcpy() that just made things worse. So strscpy not only guarantees NUL-termination (unlike strncpy), it also doesn't do unnecessary padding at the destination. But at the same time also avoids byte-at-a-time reads and writes by _allowing_ some extra NUL writes - within the size, of course - so that the whole copy can be done with word operations. It is also stable in the face of a mutable source string: it explicitly does not read the source buffer multiple times (so an implementation using "strnlen()+memcpy()" would be wrong), and does not read the source buffer past the size (like the mis-design that is strlcpy does). Finally, the return value is designed to be simple and unambiguous: if the string cannot be copied fully, it returns an actual negative error, making error handling clearer and simpler (and the caller already knows the size of the buffer). Otherwise it returns the string length of the result. However, there was one final stability issue that can be important to callers: the stability of the destination buffer. In particular, the same way we shouldn't read the source buffer more than once, we should avoid doing multiple writes to the destination buffer: first writing a potentially non-terminated string, and then terminating it with NUL at the end does not result in a stable result buffer. Yes, it gives the right result in the end, but if the rule for the destination buffer was that it is _always_ NUL-terminated even when accessed concurrently with updates, the final byte of the buffer needs to always _stay_ as a NUL byte. [ Note that "final byte is NUL" here is literally about the final byte in the destination array, not the terminating NUL at the end of the string itself. There is no attempt to try to make concurrent reads and writes give any kind of consistent string length or contents, but we do want to guarantee that there is always at least that final terminating NUL character at the end of the destination array if it existed before ] This is relevant in the kernel for the tsk->comm[] array, for example. Even without locking (for either readers or writers), we want to know that while the buffer contents may be garbled, it is always a valid C string and always has a NUL character at 'comm[TASK_COMM_LEN-1]' (and never has any "out of thin air" data). So avoid any "copy possibly non-terminated string, and terminate later" behavior, and write the destination buffer only once. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
