Support displaced stepping in aarch64-linux
This patch is to support displaced stepping in aarch64-linux. A
visitor is implemented for displaced stepping, and used to record
information to fixup pc after displaced stepping if needed. Some
emit_* functions are converted to macros, and moved to
arch/aarch64-insn.{c,h} so that they can be shared.

Support catch syscall on aarch64 linux
Hi,
This patch is to support catch syscall on aarch64 linux. We
implement gdbarch method get_syscall_number for aarch64-linux,
and add aarch64-linux.xml file, which looks straightforward, however
the changes to test case doesn't.
First of all, we enable catch-syscall.exp on aarch64-linux target,
but skip the multi_arch testing on current stage. I plan to touch
multi arch debugging on aarch64-linux later.
Then, when I run catch-syscall.exp on aarch64-linux, gcc errors that
SYS_pipe isn't defined. We find that aarch64 kernel only has pipe2
syscall and libc already convert pipe to pipe2. As a result, I change
catch-syscall.c to use SYS_pipe if it is defined, otherwise use
SYS_pipe2 instead. The vector all_syscalls in catch-syscall.exp can't
be pre-determined, so I add a new proc setup_all_syscalls to fill it,
according to the availability of SYS_pipe.
Regression tested on {x86_64, aarch64}-linux x {native, gdbserver}.

/* Signal frame handling.
|
|
|
|
|
Fix issue #15778: GDB Aarch64 signal frame unwinder issue
The root cause of this issue is unwinder of "#3 <signal handler called>"
doesn't supply right values of registers.
When GDB want to get the previous frame of "#3 <signal handler called>",
it will call cache init function of unwinder "aarch64_linux_sigframe_init".
The address or the value of the registers is get from this function.
So the bug is inside thie function.
I check the asm code of "#3 <signal handler called>":
(gdb) frame 3
(gdb) p $pc
$1 = (void (*)()) 0x7f931fa4d0
(gdb) disassemble $pc, +10
Dump of assembler code from 0x7f931fa4d0 to 0x7f931fa4da:
=> 0x0000007f931fa4d0: mov x8, #0x8b // #139
0x0000007f931fa4d4: svc #0x0
0x0000007f931fa4d8: nop
This is the syscall sys_rt_sigreturn, Linux kernel function "restore_sigframe"
will set the frame:
for (i = 0; i < 31; i++)
__get_user_error(regs->regs[i], &sf->uc.uc_mcontext.regs[i],
err);
__get_user_error(regs->sp, &sf->uc.uc_mcontext.sp, err);
__get_user_error(regs->pc, &sf->uc.uc_mcontext.pc, err);
The struct of uc_mcontext is:
struct sigcontext {
__u64 fault_address;
/* AArch64 registers */
__u64 regs[31];
__u64 sp;
__u64 pc;
__u64 pstate;
/* 4K reserved for FP/SIMD state and future expansion */
__u8 __reserved[4096] __attribute__((__aligned__(16)));
};
But in GDB function "aarch64_linux_sigframe_init", the code the get address
of registers is:
for (i = 0; i < 31; i++)
{
trad_frame_set_reg_addr (this_cache,
AARCH64_X0_REGNUM + i,
sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET
+ i * AARCH64_SIGCONTEXT_REG_SIZE);
}
trad_frame_set_reg_addr (this_cache, AARCH64_FP_REGNUM, fp);
trad_frame_set_reg_addr (this_cache, AARCH64_LR_REGNUM, fp + 8);
trad_frame_set_reg_addr (this_cache, AARCH64_PC_REGNUM, fp + 8);
The code that get pc and sp is not right, so I change the code according
to Linux kernel code:
trad_frame_set_reg_addr (this_cache, AARCH64_SP_REGNUM,
sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET
+ 31 * AARCH64_SIGCONTEXT_REG_SIZE);
trad_frame_set_reg_addr (this_cache, AARCH64_PC_REGNUM,
sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET
+ 32 * AARCH64_SIGCONTEXT_REG_SIZE);
The issue was fixed by this change, and I did the regression test. It
also fixed a lot of other XFAIL and FAIL.

On signal delivery, the kernel will create a signal handler stack
|
|
|
|
frame and setup the return address in LR to point at restorer stub.
|
|
|
|
The signal stack frame is defined by:
|
|
|
|
|
|
|
|
struct rt_sigframe
|
|
|
|
{
|
|
|
|
siginfo_t info;
|
|
|
|
struct ucontext uc;
|
|
|
|
};
|
|
|
|
|
|
|
|
typedef struct
|
|
|
|
{
|
|
|
|
... 128 bytes
|
|
|
|
} siginfo_t;
|
|
|
|
|
|
|
|
The ucontext has the following form:
|
|
|
|
struct ucontext
|
|
|
|
{
|
|
|
|
unsigned long uc_flags;
|
|
|
|
struct ucontext *uc_link;
|
|
|
|
stack_t uc_stack;
|
|
|
|
sigset_t uc_sigmask;
|
|
|
|
struct sigcontext uc_mcontext;
|
|
|
|
};
|
|
|
|
|
|
|
|
typedef struct sigaltstack
|
|
|
|
{
|
|
|
|
void *ss_sp;
|
|
|
|
int ss_flags;
|
|
|
|
size_t ss_size;
|
|
|
|
} stack_t;
|
|
|
|
|
|
|
|
struct sigcontext
|
|
|
|
{
|
|
|
|
unsigned long fault_address;
|
|
|
|
unsigned long regs[31];
|
|
|
|
unsigned long sp; / * 31 * /
|
|
|
|
unsigned long pc; / * 32 * /
|
|
|
|
unsigned long pstate; / * 33 * /
|
|
|
|
__u8 __reserved[4096]
|
|
|
|
};
|
|
|
|
|
|
|
|
The restorer stub will always have the form:
|
|
|
|
|
|
|
|

|
|
|
|

to Linux kernel code:
trad_frame_set_reg_addr (this_cache, AARCH64_SP_REGNUM,
sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET
+ 31 * AARCH64_SIGCONTEXT_REG_SIZE);
trad_frame_set_reg_addr (this_cache, AARCH64_PC_REGNUM,
sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET
+ 32 * AARCH64_SIGCONTEXT_REG_SIZE);
The issue was fixed by this change, and I did the regression test. It
also fixed a lot of other XFAIL and FAIL.

Rename _const functions to use overloading instead
This renames a few functions -- skip_spaces_const,
skip_to_space_const, get_number_const, extract_arg_const -- to drop
the "_const" suffix and instead rely on overloading.
This makes future const fixes simpler by reducing the number of lines
that must be changed. I think it is also not any less clear, as all
these functions have the same interface as their non-const versions by
design. Furthermore there's an example of using an overload in-tree
already, namely check_for_argument.
This patch was largely created using some perl one-liners; then a few
fixes were applied by hand.

Remove `expout*' globals from parser-defs.h
This commit removes the "expout*" globals from our parser code, turning
them into a structure that is passed when an expression needs to be
evaluated. This is the initial step to make our parser less
"globalized".
This is mostly a mechanical patch, which creates a structure containing
the "expout*" globals and then modify all the functions that handle them
in order to take the structure as argument. It is big, and has been
reviewed at least 4 times, so I think everything is covered.

Remove `expout*' globals from parser-defs.h
This commit removes the "expout*" globals from our parser code, turning
them into a structure that is passed when an expression needs to be
evaluated. This is the initial step to make our parser less
"globalized".
This is mostly a mechanical patch, which creates a structure containing
the "expout*" globals and then modify all the functions that handle them
in order to take the structure as argument. It is big, and has been
reviewed at least 4 times, so I think everything is covered.

Remove `expout*' globals from parser-defs.h
This commit removes the "expout*" globals from our parser code, turning
them into a structure that is passed when an expression needs to be
evaluated. This is the initial step to make our parser less
"globalized".
This is mostly a mechanical patch, which creates a structure containing
the "expout*" globals and then modify all the functions that handle them
in order to take the structure as argument. It is big, and has been
reviewed at least 4 times, so I think everything is covered.

Remove `expout*' globals from parser-defs.h
This commit removes the "expout*" globals from our parser code, turning
them into a structure that is passed when an expression needs to be
evaluated. This is the initial step to make our parser less
"globalized".
This is mostly a mechanical patch, which creates a structure containing
the "expout*" globals and then modify all the functions that handle them
in order to take the structure as argument. It is big, and has been
reviewed at least 4 times, so I think everything is covered.

Support catch syscall on aarch64 linux
Hi,
This patch is to support catch syscall on aarch64 linux. We
implement gdbarch method get_syscall_number for aarch64-linux,
and add aarch64-linux.xml file, which looks straightforward, however
the changes to test case doesn't.
First of all, we enable catch-syscall.exp on aarch64-linux target,
but skip the multi_arch testing on current stage. I plan to touch
multi arch debugging on aarch64-linux later.
Then, when I run catch-syscall.exp on aarch64-linux, gcc errors that
SYS_pipe isn't defined. We find that aarch64 kernel only has pipe2
syscall and libc already convert pipe to pipe2. As a result, I change
catch-syscall.c to use SYS_pipe if it is defined, otherwise use
SYS_pipe2 instead. The vector all_syscalls in catch-syscall.exp can't
be pre-determined, so I add a new proc setup_all_syscalls to fill it,
according to the availability of SYS_pipe.
Regression tested on {x86_64, aarch64}-linux x {native, gdbserver}.

Process record for aarch64-linux syscall
This patch updates the syscalls in sync with syscalls/aarch64-linux.xml.
Some syscalls are still not supported by gdb/linux-record.c yet. Mark
them UNSUPPORTED_SYSCALL_MAP.
This patch fixes the following test fail,
Process record and replay target doesn't support syscall number 56^M
Process record: failed to record execution log.^M
^M
Program stopped.^M
0x00000020000e9dfc in open () from /lib/aarch64-linux-gnu/libc.so.6^M

Process record for aarch64-linux syscall
This patch updates the syscalls in sync with syscalls/aarch64-linux.xml.
Some syscalls are still not supported by gdb/linux-record.c yet. Mark
them UNSUPPORTED_SYSCALL_MAP.
This patch fixes the following test fail,
Process record and replay target doesn't support syscall number 56^M
Process record: failed to record execution log.^M
^M

Support catch syscall on aarch64 linux
Hi,
This patch is to support catch syscall on aarch64 linux. We
implement gdbarch method get_syscall_number for aarch64-linux,
and add aarch64-linux.xml file, which looks straightforward, however
the changes to test case doesn't.
First of all, we enable catch-syscall.exp on aarch64-linux target,
but skip the multi_arch testing on current stage. I plan to touch
multi arch debugging on aarch64-linux later.
Then, when I run catch-syscall.exp on aarch64-linux, gcc errors that
SYS_pipe isn't defined. We find that aarch64 kernel only has pipe2
syscall and libc already convert pipe to pipe2. As a result, I change
catch-syscall.c to use SYS_pipe if it is defined, otherwise use
SYS_pipe2 instead. The vector all_syscalls in catch-syscall.exp can't
be pre-determined, so I add a new proc setup_all_syscalls to fill it,
according to the availability of SYS_pipe.
Regression tested on {x86_64, aarch64}-linux x {native, gdbserver}.

gdb/linux-record: Fix readdir and getdents handling
getdents buffer size is given in bytes, not dirent entries (which have
variable size anyway). We don't need size_dirent and size_dirent64 for
this reason.
readdir, on the other hand, needs size of old_linux_dirent, which is
a somewhat different structure. Accordingly, rename size_dirent
to size_old_dirent.

size_dirent{,64}, add size_old_dirent.

gdb/linux-record: Fix sizes of sigaction and sigset_t
The values were mistakenly set to size of glibc's sigset_t (128 bytes)
and sigaction (140 or 152 bytes) instead of the kernel ones. The kernel
has 4 or 8 byte old_sigset_t, 8 byte sigset_t, 16 or 32 byte old_sigaction,
20 or 32 byte sigaction.

Support catch syscall on aarch64 linux
Hi,
This patch is to support catch syscall on aarch64 linux. We
implement gdbarch method get_syscall_number for aarch64-linux,
and add aarch64-linux.xml file, which looks straightforward, however
the changes to test case doesn't.
First of all, we enable catch-syscall.exp on aarch64-linux target,
but skip the multi_arch testing on current stage. I plan to touch
multi arch debugging on aarch64-linux later.
Then, when I run catch-syscall.exp on aarch64-linux, gcc errors that
SYS_pipe isn't defined. We find that aarch64 kernel only has pipe2
syscall and libc already convert pipe to pipe2. As a result, I change
catch-syscall.c to use SYS_pipe if it is defined, otherwise use
SYS_pipe2 instead. The vector all_syscalls in catch-syscall.exp can't
be pre-determined, so I add a new proc setup_all_syscalls to fill it,
according to the availability of SYS_pipe.
Regression tested on {x86_64, aarch64}-linux x {native, gdbserver}.

Support displaced stepping in aarch64-linux
This patch is to support displaced stepping in aarch64-linux. A
visitor is implemented for displaced stepping, and used to record
information to fixup pc after displaced stepping if needed. Some
emit_* functions are converted to macros, and moved to
arch/aarch64-insn.{c,h} so that they can be shared.
