Rich Felker 269d193820 fix wrong sigaction syscall ABI on mips*, or1k, microblaze, riscv64 ... we wrongly defined a dummy SA_RESTORER flag on these archs, despite the kernel interface not actually having such a feature. on archs which lack SA_RESTORER, the kernel sigaction structure also lacks the restorer function pointer member, which means the signal mask appears at a different offset. the kernel was thereby interpreting the bits of the code address as part of the signal set to be masked while handling the signal. this patch removes the erroneous SA_RESTORER definitions from archs which do not have it, makes access to the member conditional on whether SA_RESTORER is defined for the arch, and removes the now-unused asm for the affected archs. because there are reportedly versions of qemu-user which also use the wrong ABI here, the old ksigaction struct size is preserved with an unused member at the end. this is harmless and mitigates the risk of such a bug turning into a buffer overflow onto the sigaction function's stack.		2023-02-09 12:33:35 -05:00
