[PATCH] ARM: Add sys_*at syscalls

2007-01-10T19:05:18Z

Later glibc requires the *at syscalls. Add them. Signed-off-by: Russell King Signed-off-by: Chris Wright

[ARM] 3338/1: old ABI compat: sys_socketcall

2006-02-16T22:36:13Z

Patch from Nicolas Pitre Commit 99595d0237926b5aba1fe4c844a011a1ba1ee1f8 forgot to intercept sys_socketcall as well. Signed-off-by: Nicolas Pitre Signed-off-by: Russell King

[ARM] 3308/1: old ABI compat: struct sockaddr_un

2006-02-08T21:19:36Z

Patch from Nicolas Pitre struct sockaddr_un loses its padding with EABI. Since the size of the structure is used as a validation test in unix_mkname(), we need to change the length argument to 110 whenever it is 112. Signed-off-by: Nicolas Pitre Signed-off-by: Russell King

[ARM] safer handling of syscall table padding

2006-01-19T12:57:01Z

ARM entry-common.S needs to know syscall table size; in itself that would not be a problem, but there's an additional constraint - some of the instructions using it want a constant that would be a multiple of 4. So we have to pad syscall table with sys_ni_syscall and that's where the trouble begins. .rept pseudo-op wants a constant expression for number of repetitions and subtraction of two labels (before and after syscall table) doesn't always get simplified to constant early enough for .rept. If labels end up in different frags, we lose. And while the frag size is large enough (slightly below 4Kb), the syscall table is about 1/3 of that. We used to get away with that, but the recent changes had been enough to trigger the breakage. Proper fix is simple: have a macro (CALL(x)) to populate the table instead of using explicit .long x and the first time we include calls.S have it defined to .equ NR_syscalls,NR_syscalls+1. Then we can find the proper amount of padding on the first inclusion simply by looking at NR_syscalls at that time. And that will be constant, no matter what. Moreover, the same trick kills the need of having an estimate of padded NR_syscalls - it will be calculated for free at the same time. Signed-off-by: Al Viro Signed-off-by: Russell King

[ARM] 3110/5: old ABI compat: multi-ABI syscall entry support

2006-01-14T16:36:12Z

Patch from Nicolas Pitre This patch adds the required code to support both user space ABIs at the same time. A second syscall table is created to include legacy ABI syscalls that need an ABI compat wrapper. Signed-off-by: Nicolas Pitre Signed-off-by: Russell King

[ARM] 3108/2: old ABI compat: statfs64 and fstatfs64

2006-01-14T16:35:03Z

Patch from Nicolas Pitre struct statfs64 has extra padding with EABI growing its size from 84 to 88. This struct is now __attribute__((packed,aligned(4))) with a small assembly wrapper to force the sz argument to 84 if it is 88 to avoid copying the extra padding over user space memory unexpecting it.

[ARM] Fix sys_sendto and sys_recvfrom 6-arg syscalls

2005-12-17T15:25:42Z

Rather than providing more wrappers for 6-arg syscalls, arrange for them to be supported as standard. This just means that we always store the 6th argument on the stack, rather than in the wrappers. This means we eliminate the wrappers for: * sys_futex * sys_arm_fadvise64_64 * sys_mbind * sys_ipc Signed-off-by: Russell King

[ARM] 2896/1: Add sys_ipc_wrapper to pass 'fifth' argument on stack

2005-09-13T21:55:00Z

Patch from George G. Davis As pointed out be Matthew Klahn , some sys_ipc() call options require six args, e.g. SEMTIMEDOP. This patch adds an ARM sys_ipc_wrapper to save the sys_ipc() 'fifth' arg on the stack. Signed-off-by: George G.

[ARM] sys_mbind needs wrapping

2005-09-09T17:35:12Z

sys_mbind is a 6-arg syscall, hence needs wrapping to save the sixth argument. Signed-off-by: Russell King

[ARM] Add memory type based allocation syscalls

2005-09-09T10:12:51Z

Add syscall numbers and syscall table entries for mbind, set_mempolicy and get_mempolicy. Signed-off-by: Russell King
