2012-10-06coredump: add a new elf note with siginfo of the signalDenys Vlasenko1-0/+5
Existing PRSTATUS note contains only si_signo, si_code, si_errno fields from the siginfo of the signal which caused core to be dumped. There are tools which try to analyze crashes for possible security implications, and they want to use, among other data, si_addr field from the SIGSEGV. This patch adds a new elf note, NT_SIGINFO, which contains the complete siginfo_t of the signal which killed the process.

2011-10-30[S390] signal race with restarting system callsMartin Schwidefsky1-0/+1
For a ERESTARTNOHAND/ERESTARTSYS/ERESTARTNOINTR restarting system call do_signal will prepare the restart of the system call with a rewind of the PSW before calling get_signal_to_deliver (where the debugger might take control). For A ERESTART_RESTARTBLOCK restarting system call do_signal will set -EINTR as return code. There are two issues with this approach: 1) strace never sees ERESTARTNOHAND, ERESTARTSYS, ERESTARTNOINTR or ERESTART_RESTARTBLOCK as the rewinding already took place or the return code has been changed to -EINTR 2) if get_signal_to_deliver does not return with a signal to deliver the restart via the repeat of the svc instruction is left in place. This opens a race if another signal is made pending before the system call instruction can be reexecuted. The original system call will be restarted even if the second signal would have ended the system call with -EINTR. These two issues can be solved by dropping the early rewind of the system call before get_signal_to_deliver has been called and by using the TIF_RESTART_SVC magic to do the restart if no signal has to be delivered. The only situation where the system call restart via the repeat of the svc instruction is appropriate is when a SA_RESTART signal is delivered to user space. Unfortunately this breaks inferior calls by the debugger again. The system call number and the length of the system call instruction is lost over the inferior call and user space will see ERESTARTNOHAND/ ERESTARTSYS/ERESTARTNOINTR/ERESTART_RESTARTBLOCK. To correct this a new ptrace interface is added to save/restore the system call number and system call instruction length. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2010-03-06elf coredump: add extended numbering supportDaisuke HATAYAMA1-1/+25
The current ELF dumper implementation can produce broken corefiles if program headers exceed 65535. This number is determined by the number of vmas which the process have. In particular, some extreme programs may use more than 65535 vmas. (If you google max_map_count, you can find some users facing this problem.) This kind of program never be able to generate correct coredumps. This patch implements ``extended numbering'' that uses sh_info field of the first section header instead of e_phnum field in order to represent upto 4294967295 vmas. This is supported by AMD64-ABI(http://www.x86-64.org/documentation.html) and Solaris(http://docs.sun.com/app/docs/doc/817-1984/). Of course, we are preparing patches for gdb and binutils.

2010-02-26[S390] Define new s390 ELF note sections in elf.hMichael Holzheu1-0/+5
S390 ELF core dump currently only contains the PSW, the general purpose registers, the floating point registers and the access registers stored in PRSTATUS/PRFPREG note sections. For analyzing s390 kernel problems additional registers are important. In order to be able to include these registers to a kernel ELF core dump, this patch adds the following five new note sections to elf.h: * NT_S390_TIMER: S390 timer register * NT_S390_TODCMP: S390 TOD comparator register * NT_S390_TODPREG: S390 TOD programmable register * NT_S390_CTRS: S390 control registers * NT_S390_PREFIX: S390 prefix register The new note sections have been already defined and accepted in the upstream binutils package.

2010-02-11ptrace: Add support for generic PTRACE_GETREGSET/PTRACE_SETREGSETSuresh Siddha1-1/+5
Generic support for PTRACE_GETREGSET/PTRACE_SETREGSET commands which export the regsets supported by each architecture using the correponding NT_* types. These NT_* types are already part of the userland ABI, used in representing the architecture specific register sets as different NOTES in an ELF core file. 'addr' parameter for the ptrace system call encode the REGSET type (using the corresppnding NT_* type) and the 'data' parameter points to the struct iovec having the user buffer and the length of that buffer. struct iovec iov = { buf, len}; ret = ptrace(PTRACE_GETREGSET/PTRACE_SETREGSET, pid, NT_XXX_TYPE, &iov); On successful completion, iov.len will be updated by the kernel specifying how much the kernel has written/read to/from the user's iov.buf. x86 extended state registers are primarily exported using this interface.

2010-02-11x86, ptrace: regset extensions to support xstateSuresh Siddha1-0/+1
Add the xstate regset support which helps extend the kernel ptrace and the core-dump interfaces to support AVX state etc. This regset interface is designed to support all the future state that gets supported using xsave/xrstor infrastructure. Looking at the memory layout saved by "xsave", one can't say which state is represented in the memory layout. This is because if a particular state is in init state, in the xsave hdr it can be represented by bit '0'. And hence we can't really say by the xsave header wether a state is in init state or the state is not saved in the memory layout. And hence the xsave memory layout available through this regset interface uses SW usable bytes [464..511] to convey what state is represented in the memory layout. First 8 bytes of the sw_usable_bytes[464..467] will be set to OS enabled xstate mask(which is same as the 64bit mask returned by the xgetbv's xCR0). The note NT_X86_XSTATE represents the extended state information in the core file, using the above mentioned memory layout.

2007-09-19[POWERPC] spufs: Cleanup ELF coredump extra notes logicMichael Ellerman1-6/+8
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.

2007-05-02[PATCH] i386: Relocate VDSO ELF headers to match mapped location with ↵Jeremy Fitzhardinge1-0/+17
COMPAT_VDSO Some versions of libc can't deal with a VDSO which doesn't have its ELF headers matching its mapped address. COMPAT_VDSO maps the VDSO at a specific system-wide fixed address. Previously this was all done at build time, on the grounds that the fixed VDSO address is always at the top of the address space. However, a hypervisor may reserve some of that address space, pushing the fixmap address down. This patch does the adjustment dynamically at runtime, depending on the runtime location of the VDSO fixmap.

This patch adds SPU elf notes to the coredump. It creates a separate note for each of /regs, /fpcr, /lslr, /decr, /decr_status, /mem, /signal1, /signal1_type, /signal2, /signal2_type, /event_mask, /event_status, /mbox_info, /ibox_info, /wbox_info, /dma_info, /proxydma_info, /object-id. A new macro, ARCH_HAVE_EXTRA_NOTES, was created for architectures to specify they have extra elf core notes. A new macro, ELF_CORE_EXTRA_NOTES_SIZE, was created so the size of the additional notes could be calculated and added to the notes phdr entry. A new macro, ELF_CORE_WRITE_EXTRA_NOTES, was created so the new notes would be written after the existing notes. The SPU coredump code resides in spufs. Stub functions are provided in the kernel which are hooked into the spufs code which does the actual work via register_arch_coredump_calls(). A new set of __spufs_<file>_read/get() functions was provided to allow the coredump code to read from the spufs files without having to lock the SPU context for each file read from.

2006-04-27Sanitise linux/audit.h for userspace consumption, split elf-em.h from elf.hDavid Woodhouse1-58/+1
Don't include <linux/sched.h> outside __KERNEL__, and split the EM_xxx definitions out of elf.h into elf-em.h so that audit.h can include just that and not pollute the namespace any further than it needs to. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-01-08[PATCH] ELF: symbol table type additionsJan Beulich1-0/+2
Needed for the Novell kernel debugger and perhaps some per-cpu data on x86_64 in the future. Cc: Andi Kleen <ak@muc.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-07[PATCH] auxiliary vector cleanupsH. J. Lu1-23/+1
The size of auxiliary vector is fixed at 42 in linux/sched.h. But it isn't very obvious when looking at linux/elf.h. This patch adds AT_VECTOR_SIZE so that we can change it if necessary when a new vector is added. Because of include file ordering problems, doing this necessitated the extraction of the AT_* symbols into a standalone header file.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+449
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
