The Sframe V2 has a new errata which introduces the SFRAME_F_FDE_FUNC_START_PCREL flag. This flag indicates the encoding of the SFrame FDE function start address field like this: - if set, sfde_func_start_address field contains the offset in bytes to the start PC of the associated function from the field itself. - if unset, sfde_func_start_address field contains the offset in bytes to the start PC of the associated function from the start of the SFrame section.

And add extra checks to enable for binutils 2.45 and if the architecture explicitly enables it. When SFrame is disabled, all the related code is also not enabled for backtrace() and _dl_find_object(), so SFrame backtracking is not used even if the binary has the SFrame segment. This patch also adds some other related fixes: * Fixed an issue with AC_CHECK_PROG_VER, where the READELF_SFRAME usage prevented specifying a different readelf through READELF environment variable at configure time. * Add an extra arch-specific internal definition, libc_cv_support_sframe, to disable --enable-sframe on architectures that have binutils but not glibc support (s390x). * Renamed the tests without the .sframe segment and move the tst-backtrace1 from pthread to debug. * Use the built compiler strip to remove the .sframe segment, instead of the system one (which might not support SFrame).

2025-07-20termios: SPEED_MAX and BAUD_MAX constantsH. Peter Anvin2-1/+5
Add constants indicating the maximum values of speed_t and baud_t. Hopefully if and when the baud_t interface is standardized then BAUD_MAX will be included in the standardization from the start. Historically, the __MAX_BAUD symbol has indicated the maximum speed_t value on at least some platforms (including glibc). However, this name would be problematic for future standardization, because it confusingly implies a reference to baud_t, not speed_t, and it is inconsistent with other limit symbols, which are all of the form *_MAX (e.g. SIZE_MAX for size_t.)

2025-07-20termios: manual: improve the explanation of various tty conceptsH. Peter Anvin1-128/+281
It is a lot easier to understand the meaning of the tty interface if it is explained from the beginning as conceptually emulating an RS232 serial port. This greatly simplifies the discussions of specific items like the meaning of line speed. Distinguish between "modem disconnect request" (deasserting DTR) and "modem disconnect" (DCD deasserted). Conflating the two terms is confusing, especially for non-RS232 devices. In particular, on most systems, a pseudo-terminal will *not* respond to a modem disconnect request by triggering a modem disconnect event for the purpose of the HUPCL flag. It is not necessarily true that the line speed has no effect on non-serial port devices: e.g. an SPI port may interpret it as the clock frequency to use; however, SPI does not use asynchronous framing bits, instead synchronization is handled by the SS# wire. Similarly, it is common but not by any means universal for interfaces that employ various forms of fixed data to symbol rate encodings to encode the data link layer bit rate rather than the physical symbol rate, which may be higher (e.g. 8B10B) or lower (e.g. QAM/Trellis), without the encoding or framing overhead. Finally, a handful of devices use the line rate for entirely nonstandard purposes. One example is Arduino USB interfaces, which often interprets changing the baud rate to 1200 baud as a command to reset the device. [ v2: removed a bogus stray chunk from editing ] Signed-off-by: H.
