This patch implements the new gdbarch method gdbarch_gdb_signal_to_target. It will be used when one wants to convert between the internal GDB signal representation (enum gdb_signal) and the target's representation. The idea of this patch came from a chat between Pedro and I on IRC, plus the discussion of my patches to add the new $_exitsignal convenience variable: <http://sourceware.org/ml/gdb-patches/2013-06/msg00452.html> <http://sourceware.org/ml/gdb-patches/2013-06/msg00352.html> What I did was to investigate, on the Linux kernel, which targets shared the signal numbers definition with the generic definition, present at <include/uapi/asm-generic/signal.h>. For the record, I used linux-3.10-rc7 as the main source of information, always looking at <arch/<ARCH_NAME>/include/uapi/asm/signal.h>. For SIGRTMAX (which defaults to _NSIG in most cases), I had to look at different signal-related files, but most of them (except MIPS) were defined to 64 anyway. Then, with all the differences in hand, I implemented the bits on each target. 2013-08-09 Sergio Durigan Junior <sergiodj@redhat.com> * linux-tdep.c: Define enum with generic signal numbers. (linux_gdb_signal_from_target): New function. (linux_gdb_signal_to_target): Likewise. (linux_init_abi): Set gdbarch_gdb_signal_{to,from}_target methods to the functions above. * linux-tdep.h (linux_gdb_signal_from_target): New prototype.

(avr_gdbarch_init): Set gdbarch_gdb_signal_{to,from}_target to the functions mentioned above. * sparc-linux-tdep.c: Define enum with differences between SPARC and generic Linux kernel signal numbers.

(mips_gdb_signal_to_target): New function. (mips_gdb_signal_from_target): Redefine to use new enum, handle only different signals from the Linux kernel generic.

/* This enum represents the signals' numbers on a generic architecture
running the Linux kernel. The definition of "generic" comes from
the file <include/uapi/asm-generic/signal.h>, from the Linux kernel
tree, which is the "de facto" implementation of signal numbers to
be used by new architecture ports.
For those architectures which have differences between the generic
standard (e.g., Alpha), we define the different signals (and *only*
those) in the specific target-dependent file (e.g.,
alpha-linux-tdep.c, for Alpha). Please refer to the architecture's
tdep file for more information.
ARM deserves a special mention here. On the file
<arch/arm/include/uapi/asm/signal.h>, it defines only one different
(and ARM-only) signal, which is SIGSWI, with the same number as
SIGRTMIN. This signal is used only for a very specific target,
called ArthurOS (from RISCOS). Therefore, we do not handle it on
the ARM-tdep file, and we can safely use the generic signal handler
here for ARM targets.
As stated above, this enum is derived from
<include/uapi/asm-generic/signal.h>, from the Linux kernel
tree. */

Therefore it reads core number off-by-one (it reads 17 instead of 6) and overruns the array. (1) Make the process name parsing more foolproof. (2) Do not trust the parsed number from /proc/PID/stat and verify it against the array size. I noticed that 'ps' gets this right, so I've peeked at its sources, and it just looks for the first ')' starting at the end. https://gitorious.org/procps/procps/source/dc072aced7250fed9b01fb05f0d672678752a63e:proc/readproc.c Look for stat2proc. Given ps does that, I believe the kernel won't ever be changed in a way that would break it. So it sounds like could do strrchr from the end of stat just as well without worry, which is simpler. gdb/ 2014-02-21 Jan Kratochvil <jan.kratochvil@redhat.com> PR gdb/16594 * common/linux-osdata.c (linux_common_core_of_thread): Find the end of process name.

Therefore it reads core number off-by-one (it reads 17 instead of 6) and overruns the array. (1) Make the process name parsing more foolproof. (2) Do not trust the parsed number from /proc/PID/stat and verify it against the array size. I noticed that 'ps' gets this right, so I've peeked at its sources, and it just looks for the first ')' starting at the end. https://gitorious.org/procps/procps/source/dc072aced7250fed9b01fb05f0d672678752a63e:proc/readproc.c Look for stat2proc. Given ps does that, I believe the kernel won't ever be changed in a way that would break it.

This patch implements the new gdbarch method gdbarch_gdb_signal_to_target. It will be used when one wants to convert between the internal GDB signal representation (enum gdb_signal) and the target's representation. The idea of this patch came from a chat between Pedro and I on IRC, plus the discussion of my patches to add the new $_exitsignal convenience variable: <http://sourceware.org/ml/gdb-patches/2013-06/msg00452.html> <http://sourceware.org/ml/gdb-patches/2013-06/msg00352.html> What I did was to investigate, on the Linux kernel, which targets shared the signal numbers definition with the generic definition, present at <include/uapi/asm-generic/signal.h>. For the record, I used linux-3.10-rc7 as the main source of information, always looking at <arch/<ARCH_NAME>/include/uapi/asm/signal.h>. For SIGRTMAX (which defaults to _NSIG in most cases), I had to look at different signal-related files, but most of them (except MIPS) were defined to 64 anyway. Then, with all the differences in hand, I implemented the bits on each target. 2013-08-09 Sergio Durigan Junior <sergiodj@redhat.com> * linux-tdep.c: Define enum with generic signal numbers.
