4Subject: [PATCH] Fix build with latest GCC 9.0 tree
5
6A recent patch [1] to fix a GCC PR [2] actually broke the GDB build.
7To fix, remove the stack pointer clobber. GCC will ignore the clobber
8marker, and will not save or restore the stack pointer.
9
10I ran "make check-gdb" on x86_64 to ensure there are no regressions.

4Subject: [PATCH] AArch64: Fix the gdb build with musl libc
5
6Including asm/sigcontext.h together with libc headers is not valid. In
7general linux headers may not work with libc headers, so mixing them
8should be avoided, especially when the linux header defines types that
9are also exposed in libc headers.
10
11In case of asm/sigcontext.h glibc happens to work because glibc signal.h
12directly includes it, but e.g. in musl libc signal.h replicates the
13sigcontext.h definitions in an abi compatible way which are in conflict
14with the linux definitions when both headers are included.
15
16Since old linux headers or old libc headers may not have the necessary
17definitions, gdb has to replicate the definitions it relies on anyway.
18Which is fine since all definitions must be ABI stable. For linux apis
19that are not available via libc headers, replicating the definitions in
20gdb is the most reliable way to use them.
21
22Note: asm/ptrace.h includes asm/sigcontext.h in some versions of linux
23headers, which is just as problematic and should be fixed in linux.
24
25gdb/ChangeLog:
26
27 * nat/aarch64-sve-linux-ptrace.h: Include signal.h instead of
28 asm/sigcontext.h.

4Subject: [PATCH] Detect invalid length field in debug frame FDE header.
5
6GDB was failing to catch cases where a corrupt ELF or core file
7contained an invalid length value in a Dwarf debug frame FDE header.
8It was checking for buffer overflow but not cases where the length was
9negative or caused pointer wrap-around.
10
11In addition to the additional validity check, this patch cleans up the
12multiple signed/unsigned conversions on the length field so that an
13unsigned representation is used consistently throughout.
14
15This patch fixes CVE-2017-9778 and PR gdb/21600.

22 * dwarf2-frame.c (read_initial_length): Be consistent about using
23 unsigned representation of length.
24 (decode_frame_entry_1): Likewise. Check for wraparound of
25 end pointer as well as buffer overflow.
