| |
| 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: |
| |
| d28015a8 movz x8, #0xad |
| d4000001 svc #0x0 |
| |
| This is a system call sys_rt_sigreturn. |
| |
| We detect signal frames by snooping the return code for the restorer |
| instruction sequence. |
| |
| The handler then needs to recover the saved register set from |
| ucontext.uc_mcontext. */ |
