Merge tag 'ptrace-cleanups-for-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull ptrace cleanups from Eric Biederman: "This set of changes removes tracehook.h, moves modification of all of the ptrace fields inside of siglock to remove races, adds a missing permission check to ptrace.c
The removal of tracehook.h is quite significant as it has been a major source of confusion in recent years. Much of that confusion was around task_work and TIF_NOTIFY_SIGNAL (which I have now decoupled making the semantics clearer).
For people who don't know tracehook.h is a vestiage of an attempt to implement uprobes like functionality that was never fully merged, and was later superseeded by uprobes when uprobes was merged. For many years now we have been removing what tracehook functionaly a little bit at a time. To the point where anything left in tracehook.h was some weird strange thing that was difficult to understand"

Simple Explanation: Th
MIPS: signal: Protect against sigaltstack wraparound
If a process uses alternative signal stack by using sigaltstack(), then that stack overflows and stack wraparound occurs.
Simple Explanation: The accurate sp order is A,B,C,D,... But now the sp points to A,B,C and A,B,C again.
This problem can reproduce by the following code:
$ cat test_sigaltstack.c #include <stdio.h> #include <signal.h> #include <stdlib.h> #include <string.h>
volatile int counter = 0;
void print_sp() { unsigned long sp;
__asm__ __volatile__("move %0, $sp" : "=r" (sp)); printf("sp = 0x%08lx\n", sp); }
void segv_handler() { int *c = NULL;
print_sp(); counter++; printf("%d\n", counter);
if (counter == 23) abort();
*c = 1; // SEGV }
int main() { int *c = NULL; char *s = malloc(SIGSTKSZ); stack_t stack; struct sigaction action;
memset(s, 0, SIGSTKSZ); stack.ss_sp = s; stack.ss_flags = 0; stack.ss_size = SIGSTKSZ; if (sigaltstack(&stack, NULL)) { printf("Failed to use sigaltstack!\n"); return -1; }
memset(&action, 0, sizeof(action)); action.sa_handler = segv_handler; action.sa_flags = SA_ONSTACK | SA_NODEFER; sigemptyset(&action.sa_mask); sigaction(SIGSEGV, &action, NULL);
*c = 0; //SEGV
if (!s) free(s);
return 0; } $ gcc test_sigaltstack.c -o test_sigaltstack $ ./test_sigaltstack sp = 0x120015c80 1 sp = 0x120015900 2 sp = 0x120015580 3 sp = 0x120015200 4 sp = 0x120014e80 5 sp = 0x120014b00 6 sp = 0x120014780 7 sp = 0x120014400 8 sp = 0x120014080 9 sp = 0x120013d00 10 sp = 0x120015c80 11 # wraparound occurs! the 11nd output is same as 1st. sp = 0x120015900 12 sp = 0x120015580 13 sp = 0x120015200 14 sp = 0x120014e80 15 sp = 0x120014b00 16 sp = 0x120014780 17 sp = 0x120014400 18 sp = 0x120014080 19 sp = 0x120013d00 20 sp = 0x120015c80 21 # wraparound occurs! the 21nd output is same as 1st. sp = 0x120015900 22 sp = 0x120015580 23 Aborted
With this patch:
$ ./test_sigaltstack sp = 0x120015c80 1 sp = 0x120015900 2 sp = 0x120015580 3 sp = 0x120015200 4 sp = 0x120014e80 5 sp = 0x120014b00 6 sp = 0x120014780 7 sp = 0x120014400 8 sp = 0x120014080 9 Segmentation fault
If we are on the alternate signal stack and would overflow it, don't. Return an always-bogus address instead so we will die with SIGSEGV.
This patch is similar with commit 83bd01024b1f ("x86: protect against sigaltstack wraparound").
