This can be triggered with root help only, but... Register the ":text:E::txt::/root/cat.txt:' rule in binfmt_misc (by root) and try launching the cat.txt file (by anyone) :) The result is - the endless recursion in the load_misc_binary -> open_exec -> load_misc_binary chain and stack overflow. There's a similar problem with binfmt_script, and there's a sh_bang memner on linux_binprm structure to handle this, but simply raising this in binfmt_misc may break some setups when the interpreter of some misc binaries is a script. So the proposal is to turn sh_bang into a bit, add a new one (the misc_bang) and raise it in load_misc_binary. After this, even if we set up the misc -> script -> misc loop for binfmts one of them will step on its own bang and exit. Signed-off-by:

SysRQ-P is not always useful on SMP systems, since it usually ends up showing the backtrace of a CPU that is doing just fine, instead of the backtrace of the CPU that is having problems. This patch adds SysRQ show-all-cpus(L), which shows the backtrace of every active CPU in the system. It skips idle CPUs because some SMP systems are just too large and we already know what the backtrace of the idle task looks like. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

I noticed that 2.6.24.2 calculates bprm->argv_len at do_execve(). But it doesn't update bprm->argv_len after "remove_arg_zero() + copy_strings_kernel()" at load_script() etc. audit_bprm() is called from search_binary_handler() and search_binary_handler() is called from load_script() etc. Thus, I think the condition check if (bprm->argv_len > (audit_argv_kb << 10)) return -E2BIG; in audit_bprm() might return wrong result when strlen(removed_arg) != strlen(spliced_args). Why not update bprm->argv_len at load_script() etc. ? By the way, 2.6.25-rc3 seems to not doing the condition check. Is the field bprm->argv_len no longer needed?

if (...) BUG(); should be replaced with BUG_ON(...) when the test has no side-effects to allow a definition of BUG_ON that drops the code completely.

Almost all implementations of pci_iomap() in the kernel, including the generic lib/iomap.c one, copies the content of a struct resource into unsigned long's which will break on 32 bits platforms with 64 bits resources. This fixes all definitions of pci_iomap() to use resource_size_t. I also "fixed" the 64bits arch for consistency. Signed-off-by:

16 kB is often no longer enough for a normal boot of an UP system. And even less when people e.g. use suspend. 17 seems to be a more reasonable default for current kernels on current hardware (it's just the default, anyone who is memory limited can still lower it). Signed-off-by:

Add a few __ref to tech modpost to ignore the references. This is just papering over the fact that the cpu hotplug code is fragile with respect to use of HOTPLUG_CPU and in many cases rely on __cpuinit to get rid of code when HOTPLUG_CPU is not enabled. For now this is the least invasive change. Signed-off-by:
