2021-11-22 | [gdb/build] Fix x86_64 x32 build | Tom de Vries | 1 | -0/+4 | |
A build error on x86_64 with x32 abi was reported here ( https://sourceware.org/pipermail/gdb/2021-November/049787.html ): ... gdb/nat/amd64-linux-siginfo.c:280:42: error: \ 'struct compat_x32_siginfo_t::<unnamed union>::<unnamed>' has no member \ named 'si_addr_bnd' 280 | #define cpt_si_lower _sifields._sigfault.si_addr_bnd._lower | ^~~~~~~~~~~ gdb/nat/amd64-linux-siginfo.c:337:38: note: in expansion of macro 'cpt_si_lower' 337 | to->cpt_si_lower = from_ptrace.cpt_si_lower; | ^~~~~~~~~~~~ ... The problem is that code added in commit d3d7d1ba3bb "[gdb/tdep] Handle si_addr_bnd in compat_siginfo_from_siginfo" doesn't compile on an x86_64 x32 setup, because compat_x32_siginfo_t doesn't have the si_addr_bnd fields. Fix this conservatively by disabling the code for x32. Tested on x86_64-linux. | |||||
2021-06-07 | nat/amd64-linux-siginfo.c: Remove typedefs | Pedro Alves | 1 | -14/+14 | |
Since GDB is written in C++ now, we don't need struct/union typedefs any more.

2021-06-07 | nat/amd64-linux-siginfo.c: Move align attribute from typedef to struct | Pedro Alves | 1 | -2/+2 | |
Compiling GDB with current git Clang (future 13) fails with (among other problems), this issue: $ make nat/amd64-linux-siginfo.o CXX nat/amd64-linux-siginfo.o src/gdb/nat/amd64-linux-siginfo.c:590:35: warning: passing 4-byte aligned argument to 8-byte aligned parameter 1 of 'compat_x32_siginfo_from_siginfo' may result in an unaligned pointer access [-Walign-mismatch] compat_x32_siginfo_from_siginfo ((struct compat_x32_siginfo *) inf, ^ 1 warning generated. The problem is that: - The flagged code is casting to "struct compat_x32_siginfo" pointer directly instead of to a pointer to the compat_x32_siginfo_t typedef. The called function is declared with a compat_x32_siginfo_t typedef pointer parameter. - Only the typedef has the __aligned__ attribute. Fix this by moving the attribute to the struct, so both struct and typedef have the same alignment. The next patch removes the typedefs. gdb/ChangeLog: yyyy-mm-dd Pedro Alves <pedro@palves.net> * nat/amd64-linux-siginfo.c (compat_x32_siginfo_t): Move __attribute__ __aligned__ from the typedef to the struct. | |||||
2021-02-18 | amd64-linux-siginfo.c: Adjust include order to avoid gnulib error | Kevin Buettner | 1 | -1/+1 | |
On Fedora rawhide, after updating to glibc-2.33, I'm seeing the following build failure: CXX nat/amd64-linux-siginfo.o In file included from /usr/include/bits/sigstksz.h:24, from /usr/include/signal.h:315, from ../gnulib/import/signal.h:52, from /ironwood1/sourceware-git/rawhide-gnulib/bld/../../worktree-gnulib/gdbserver/../gdb/nat/amd64-linux-siginfo.c:20: ../gnulib/import/unistd.h:663:3: error: #error "Please include config.h first." 663 | #error "Please include config.h first." | ^~~~~ glibc-2.33 has changed signal.h to now include <bits/sigstksz.h> which, in turn, includes <unistd.h>. For a gdb build, this causes the gnulib version of unistd.h to be pulled in first. The build failure shown above happens because gnulib's config.h has not been included before the include of <signal.h>. The fix is simple - we just rearrange the order of the header file includes to make sure that gdbsupport/commondefs.h is included before attempting to include signal.h. Note that gdbsupport/commondefs.h includes <gnulib/config.h>. Build and regression tested on Fedora 33. On Fedora rawhide, GDB builds again. gdb/ChangeLog: * nat/amd64-linux-siginfo.c: Include "gdbsupport/common-defs.h" (which in turn includes <gnulib/config.h>) before include of <signal.h>. | |||||

2019-07-09 | Rename common to gdbsupport | Tom Tromey | 1 | -1/+1 | |
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

2016-07-26 | Fix PR gdb/20287 - x32 and "gdb_static_assert (sizeof (nat_siginfo_t) == ↵ | Pedro Alves | 1 | -139/+159 | |
sizeof (siginfo_t))" Building an x32 gdb trips on a static assertion: In file included from .../src/gdb/common/common-defs.h:71:0, from .../src/gdb/nat/amd64-linux-siginfo.c:21: .../src/gdb/common/gdb_assert.h:26:66: error: size of array ‘never_defined_just_used_for_checking’ is negative extern int never_defined_just_used_for_checking[(expr) ? 1 : -1] ^ .../src/gdb/nat/amd64-linux-siginfo.c:113:1: note: in expansion of macro ‘gdb_static_assert’ gdb_static_assert (sizeof (nat_siginfo_t) == sizeof (siginfo_t)); ^ The problem is that the way nat_siginfo_t is defined, it can only match the host's siginfo_t object when gdb is built as a 64-bit program. Several bits of nat_siginfo_t are off: - nat_siginfo_t's _pad field's definition is: int _pad[((128 / sizeof (int)) - 4)]; while /usr/include/bits/siginfo.h has: # define __SI_MAX_SIZE 128 # if __WORDSIZE == 64 # define __SI_PAD_SIZE ((__SI_MAX_SIZE / sizeof (int)) - 4) # else # define __SI_PAD_SIZE ((__SI_MAX_SIZE / sizeof (int)) - 3) # endif and __WORDSIZE == 32 for x32. This is what causes the size of nat_siginfo_t to be wrong and the assertion to fail. - the nat_clock_t type is incorrect for 64-bit. We have this: /* For native 64-bit, clock_t in _sigchld is 64bit aligned at 4 bytes. */ typedef long __attribute__ ((__aligned__ (4))) nat_clock_t; however, /usr/include/bits/siginfo.h has: # if defined __x86_64__ && __WORDSIZE == 32 /* si_utime and si_stime must be 4 byte aligned for x32 to match the kernel. We align siginfo_t to 8 bytes so that si_utime and si_stime are actually aligned to 8 bytes since their offsets are multiple of 8 bytes. */ typedef __clock_t __attribute__ ((__aligned__ (4))) __sigchld_clock_t; # define __SI_ALIGNMENT __attribute__ ((__aligned__ (8))) # else typedef __clock_t __sigchld_clock_t; # define __SI_ALIGNMENT # endif So we're currently forcing 4-byte alignment on clock_t, when it should only be so for x32, not 64-bit. The fix: - Leaves nat_siginfo_t strictly for the 64-bit ABI. - Adds a new typedef for the siginfo type that ptrace uses (ptrace_siginfo_t). An x32 gdb always gets/sets an x32 siginfo_t type with PTRACE_GETSIGINFO/PTRACE_SETSIGINFO. - Uses this new ptrace_siginfo_t type instead of nat_siginfo_t as the intermediate conversion type. gdb/ChangeLog: 2016-07-26 Pedro Alves <palves@redhat.com> * amd64-linux-nat.c (amd64_linux_siginfo_fixup): Rename 'native' parameter to 'ptrace'. * nat/amd64-linux-siginfo.c (GDB_SI_SIZE): New define.

2016-02-02 | Adaptation of siginfo fixup for the new bnd fields | Walfred Tedeschi | 1 | -100/+214 | |
New bnds fields will be always present for x86 architecture. Fixup for compatibility layer 32bits has to be fixed. It was added the nat_siginfo to serving as intermediate step between kernel provided siginfo and the fix up routine. When executing compat_siginfo_from_siginfo or compat_x32_siginfo_from_siginfo first the buffer read from the kernel are converted into the nat_signfo for homogenization, then the fields of nat_siginfo are use to set the compat and compat_x32 siginfo fields. In other to make this conversion independent of the system where gdb is compiled the most complete version of the siginfo, named as native siginfo, is used internally as an intermediate step. Conversion using nat_siginfo is exemplified below: compat_siginfo_from_siginfo or compat_x32_siginfo_from_siginfo: buffer (from the kernel) -> nat_siginfo -> 32 / X32 siginfo (memcpy) (field by field) siginfo_from_compat_x32_siginfo or siginfo_from_compat_siginfo: 32 / X32 siginfo -> nat_siginfo -> buffer (to the kernel) (field by field) (memcpy) Caveat: No support for MPX on x32. 2016-02-02 Walfred Tedeschi <walfred.tedeschi@intel.com> gdb/ChangeLog: * amd64-linux-siginfo.c (nat_siginfo_t, nat_sigval_t, nat_timeval): New types.
