Since commit 1751e8a6 ("Rename superblock flags (MS_xyz -> SB_xyz)"), scripts/gdb should be updated to replace MS_xyz with SB_xyz. This change didn't directly affect the running operation of scripts/gdb until commit e262e32d "vfs: Suppress MS_* flag defs within the kernel unless explicitly enabled" removed the definitions used by constants.py. Update constants.py.in to utilise the new internal flags, matching the implementation at fs/proc_namespace.c::show_sb_opts. Note to stable, e262e32d landed in v5.0-rc1 (which was just released), so we'll want this picked back to 5.0 stable once this patch hits mainline (akpm just picked it up). Without this, debugging a kernel a kernel via GDB+QEMU is broken in the 5.0 release.

A bug is present in GDB which causes early string termination when parsing variables. This has been reported [0], but we should ensure that we can support at least basic printing of the core kernel strings. For current gdb version (has been tested with 7.3 and 8.1), 'lx-version' only prints one character. (gdb) lx-version L(gdb) This can be fixed by casting 'linux_banner' as (char *). (gdb) lx-version Linux version 4.19.0-rc1+ (changbin@acer) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #21 SMP Sat Sep 1 21:43:30 CST 2018 [0] https://sourceware.org/bugzilla/show_bug.cgi?id=20077 [kbingham@kernel.org: add detail to commit message] Link: http://lkml.kernel.org/r/20181111162035.8356-1-kieran.bingham@ideasonboard.com Fixes: 2d061d99 ("scripts/gdb: add version command") Signed-off-by:

lx-fdtdump dumps the flattened device tree passed to the kernel from the bootloader to the filename specified as the command argument. If no argument is provided it defaults to fdtdump.dtb. This then allows further post processing on the machine running GDB. The fdt header is also also printed in the GDB console. For example: (gdb) lx-fdtdump fdt_magic: 0xD00DFEED fdt_totalsize: 0xC108 off_dt_struct: 0x38 off_dt_strings: 0x3804 off_mem_rsvmap: 0x28 version: 17 last_comp_version: 16 Dumped fdt to fdtdump.dtb >fdtdump fdtdump.dtb | less This command is useful as the bootloader can often re-write parts of the device tree, and this can sometimes cause the kernel to not boot.

lx-mounts will identify current mount points based on the 'init_task' namespace by default, as we do not yet have a kernel thread list implementation to select the current running thread. Optionally, a user can specify a PID to list from that process' namespace Link: http://lkml.kernel.org/r/e614c7bc32d2350b4ff1627ec761a7148e65bfe6.1462865983.git.jan.kiszka@siemens.com Signed-off-by:

Provide iomem_resource and ioports_resource printers and command hooks It can be quite interesting to halt the kernel as it's booting and check to see this list as it is being populated. It should be useful in the event that a kernel is not booting, you can identify what memory resources have been registered Link: http://lkml.kernel.org/r/f0a6b9fa9c92af4d7ed2e7343ccc84150e9c6fc5.1462865983.git.jan.kiszka@siemens.com Signed-off-by:

lx-version Report the Linux Version of the current kernel. Add a command to identify the version specified by the banner in the debugged kernel. This lets the user identify the kernel of the running kernel, and will let later scripts compare the banner of the attached kernel against the banner in the vmlinux symbols files to verify that the files are correct.
