x86: ioperm user_regset

2008-10-12T10:05:55+00:00

This adds a user_regset type for the x86 io permissions bitmap. This makes it appear in core dumps (when ioperm has been used). It will also make it visible to debuggers in the future. Signed-off-by: Roland McGrath Signed-off-by: H. Peter Anvin [conflict resolutions: Signed-off-by: Ingo Molnar ]

powerpc: Update for VSX core file and ptrace

2008-07-01T04:47:09+00:00

This correctly hooks the VSX dump into Roland McGrath core file infrastructure. It adds the VSX dump information as an additional elf note in the core file (after talking more to the tool chain/gdb guys). This also ensures the formats are consistent between signals, ptrace and core files. Signed-off-by: Michael Neuling Signed-off-by: Paul Mackerras

[POWERPC] Add SPE registers to core dumps

2008-02-07T09:40:23+00:00

This makes the SPE register data appear in ELF core dumps, using the new n_type value NT_PPC_SPE (0x101). This new note type is not used by any consumers of core files yet, but support can be added. I don't even have any hardware with SPE capabilities, so I've never seen such a note. But this demonstrates how simple it is to export register information in core dumps when the user_regset style is used for the low-level code.

x86: x86 core dump TLS

2008-01-30T12:31:56+00:00

This makes ELF core dumps of 32-bit processes include a new note type NT_386_TLS (0x200) giving the contents of the TLS slots in struct user_desc format. This lets post mortem examination figure out what the segment registers mean like the debugger does with get_thread_area on a live process.

increase AT_VECTOR_SIZE to terminate saved_auxv properly

2007-10-17T15:43:00+00:00

include/asm-powerpc/elf.h has 6 entries in ARCH_DLINFO. fs/binfmt_elf.c has 14 unconditional NEW_AUX_ENT entries and 2 conditional NEW_AUX_ENT entries. So in the worst case, saved_auxv does not get an AT_NULL entry at the end. The saved_auxv array must be terminated with an AT_NULL entry. Make the size of mm_struct->saved_auxv arch dependend, based on the number of ARCH_DLINFO entries.

powerpc: add Altivec/VMX state to coredumps

2007-10-17T15:42:44+00:00

Update dump_task_altivec() (which has so far never been put to use) so that it dumps the Altivec/VMX registers (VR[0] - VR[31], VSCR and VRSAVE) in the same format as the ptrace get_vrregs(), and add the appropriate glue typedef and #defines to make it work. A new note type of NT_PPC_VMX was chosen to be 0x100 (arbitrarily) because it allows the low range values to be used for more generic purposes and 0x100 seems an adequate starting point for PowerPC extensions.

[POWERPC] spufs: Cleanup ELF coredump extra notes logic

2007-09-19T05:12:19+00:00

To start with, arch_notes_size() etc. is a little too ambiguous a name for my liking, so change the function names to be more explicit. Calling through macros is ugly, especially with hidden parameters, so don't do that, call the routines directly. Use ARCH_HAVE_EXTRA_ELF_NOTES as the only flag, and based on it decide whether we want the extern declarations or the empty versions. Since we have empty routines, actually use them in the coredump code to save a few #ifdefs. We want to change the handling of foffset so that the write routine updates foffset as it goes, instead of using file->f_pos (so that writing to a pipe works). So pass foffset to the write routine, and for now just set it to file->f_pos at the end of writing. It should also be possible for the write routine to fail, so change it to return int and treat a non-zero return as failure.
