score: fix off-by-one index into syscall table

2012-01-23T16:38:49Z

If the provided system call number is equal to __NR_syscalls, the current check will pass and a function pointer just after the system call table may be called, since sys_call_table is an array with total size __NR_syscalls. Whether or not this is a security bug depends on what the compiler puts immediately after the system call table. It's likely that this won't do anything bad because there is an additional NULL check on the syscall entry, but if there happens to be a non-NULL value immediately after the system call table, this may result in local privilege escalation.

score: Use HAVE_MEMBLOCK_NODE_MAP

2011-12-08T18:22:09Z

score used early_node_map[] just to prime free_area_init_nodes(). Now memblock can be used for the same purpose and early_node_map[] is scheduled to be dropped. Use memblock instead. Signed-off-by: Tejun Heo Cc: Benjamin Herrenschmidt Cc: Yinghai Lu Cc: Chen Liqin Cc: Lennox Wu

modules: make arch's use default loader hooks

2011-07-24T12:36:04Z

This patch removes all the module loader hook implementations in the architecture specific code where the functionality is the same as that now provided by the recently added default hooks.

ptrace: change signature of arch_ptrace()

2010-10-28T01:03:10Z

Fix up the arguments to arch_ptrace() to take account of the fact that @addr and @data are now unsigned long rather than long as of a preceding patch in this series.

Make do_execve() take a const filename pointer

2010-08-18T01:07:43Z

Make do_execve() take a const filename pointer so that kernel_execve() compiles correctly on ARM: arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type This also requires the argv and envp arguments to be consted twice, once for the pointer array and once for the strings the array points to. This is because do_execve() passes a pointer to the filename (now const) to copy_strings_kernel(). A simpler alternative would be to cast the filename pointer in do_execve() when it's passed to copy_strings_kernel(). do_execve() may not change any of the strings it is passed as part of the argv or envp lists as they are some of them in .rodata, so marking these strings as const should be fine. Further kernel_execve() and sys_execve() need to be changed to match. This has been test built on x86_64, frv, arm and mips.
