+Subject: [PATCH] PR gdb/33747: gdb/ser-unix: modernize Linux custom baud
+ rate support
+
+The Linux custom baud rate implementation previously accessed the
+struct termios members c_ispeed and c_ospeed directly. These fields
+exist in glibc but are not exposed by musl, causing builds to fail on
+musl-based systems.
+
+Update set_custom_baudrate_linux to use a capability-based approach,
+with three distinct code paths:
+
+1) If POSIX cfsetispeed/cfsetospeed accept arbitrary baud rates
+ (HAVE_CFSETSPEED_ARBITRARY), use them to set input and output
+ speeds.
+
+2) Else if Linux termios2 interface is available (TCGETS2/BOTHER),
+ use it to support arbitrary baud rates.
+
+3) Else if legacy struct termios supports c_ispeed/c_ospeed, use
+ the TCGETS/TCSETS fallback (primarily for glibc on older
+ architectures).
+
+4) Otherwise, emit an error indicating that custom baud rates are
+ unsupported on this platform.
+
+This preserves existing behavior on glibc systems while restoring
+build compatibility with musl and other libc implementations.

+Subject: [PATCH] PR gdb/33926: gdbsupport: fix AArch64 struct user_gcs
+ redefinition on musl
+
+Building GDB 17.1 for AArch64 against Linux kernel headers >= 6.13
+with musl libc fails with:
+
+ gdbserver/linux-aarch64-low.cc:42: error: redefinition of 'struct user_gcs'
+ gdb/aarch64-linux-nat.c:54: error: redefinition of 'struct user_gcs'
+
+The fallback definition of struct user_gcs in gdb/arch/aarch64-gcs-linux.h
+was guarded by #ifndef GCS_MAGIC. GCS_MAGIC is defined in
+<asm/sigcontext.h>. On glibc systems, <asm/sigcontext.h> is pulled in
+implicitly, so the guard works. On musl, it is never included implicitly,
+so GCS_MAGIC is not defined, the guard does not fire, and struct user_gcs
+is defined twice.
+
+Fix this by replacing the GCS_MAGIC guard with HAVE_STRUCT_USER_GCS,
+set by an AC_CACHE_CHECK probe in gdbsupport/configure.ac that includes
+<asm/ptrace.h> directly. The probe is fully libc-agnostic.
+
+gdbsupport/config.h is shared by both the gdb and gdbserver builds, so
+this single probe fixes the redefinition error in both translation units.
+
+Backport of upstream fix by Thiago Jung Bauermann:
+ [PATCH v4 6/6] GDB: aarch64-linux: Fix build failure on musl systems
+ https://sourceware.org/pipermail/gdb-patches/2026-February/225010.html
+
+adapted to the GDB 17.1 layout where struct user_gcs still resides in
+gdb/arch/aarch64-gcs-linux.h.
