10 | ( rsp is obviously invariant across normal function calls. (gcc can 'merge' | ||
11 | functions when it sees tail-call optimization possibilities) rflags is | ||
12 | clobbered. Leftover arguments are passed over the stack frame.) | ||
13 | |||
14 | [*] In the frame-pointers case rbp is fixed to the stack frame. | ||
15 | |||
16 | [**] for struct return values wider than 64 bits the return convention is a | ||
17 | bit more complex: up to 128 bits width we return small structures | ||
18 | straight in rax, rdx. For structures larger than that (3 words or | ||
19 | larger) the caller puts a pointer to an on-stack return struct | ||
20 | [allocated in the caller's stack frame] into the first argument - i.e. | ||
21 | into rdi. All other arguments shift up by one in this case. | ||
22 | Fortunately this case is rare in the kernel. | ||
23 | |||
24 | For 32-bit we have the following conventions - kernel is built with | ||
25 | -mregparm=3 and -freg-struct-return: | ||

36 | |||
37 | [*] In the frame-pointers case ebp is fixed to the stack frame. | ||
38 | |||
39 | [**] We build with -freg-struct-return, which on 32-bit means similar | ||
40 | semantics as on 64-bit: edx can be used for a second return value | ||
41 | (i.e. covering integer and structure sizes up to 64 bits) - after that | ||
42 | it gets more complex and more expensive: 3-word or larger struct returns | ||
43 | get done in the caller's frame and the pointer to the return struct goes | ||
44 | into regparm0, i.e. eax - the other arguments shift up and the | ||
45 | function's register parameters degenerate to regparm=2 in essence. | ||

2 | * GCC stack protector support. | ||
3 | * | ||
4 | * Stack protector works by putting predefined pattern at the start of | ||
5 | * the stack frame and verifying that it hasn't been overwritten when | ||
6 | * returning from the function. The pattern is called stack canary | ||
7 | * and unfortunately gcc requires it to be at a fixed offset from %gs. | ||
8 | * On x86_64, the offset is 40 bytes and on x86_32 20 bytes. x86_64 | ||
9 | * and x86_32 use segment registers differently and thus handles this | ||
10 | * requirement differently. | ||
11 | * | ||
12 | * On x86_64, %gs is shared by percpu area and stack canary. All | ||
13 | * percpu symbols are zero based and %gs points to the base of percpu | ||
14 | * area. The first occupant of the percpu area is always | ||
15 | * irq_stack_union which contains stack_canary at offset 40. Userland | ||
16 | * %gs is always saved and restored on kernel entry and exit using | ||
17 | * swapgs, so stack protector doesn't add any complexity there. | ||
18 | * | ||
19 | * On x86_32, it's slightly more complicated. As in x86_64, %gs is | ||
20 | * used for userland TLS. Unfortunately, some processors are much | ||
21 | * slower at loading segment registers with different value when | ||
22 | * entering and leaving the kernel, so the kernel uses %fs for percpu | ||
23 | * area and manages %gs lazily so that %gs is switched only when | ||
24 | * necessary, usually during task switch. | ||
25 | * | ||
26 | * As gcc requires the stack canary at %gs:20, %gs can't be managed | ||
27 | * lazily if stack protector is enabled, so the kernel saves and | ||
28 | * restores userland %gs on kernel entry and exit. This behavior is | ||
29 | * controlled by CONFIG_X86_32_LAZY_GS and accessors are defined in | ||
30 | * system.h to hide the details. | ||
