I was looking into random driver code and found a suspicious looking memcpy() in drivers/char/ipmi/ipmi_bt_sm.c on 2.6.17-rc1: if ((size < 2) || (size > IPMI_MAX_MSG_LENGTH)) return -1; ... memcpy(bt->write_data + 3, data + 1, size - 1); where sizeof bt->write_data is IPMI_MAX_MSG_LENGTH. It looks like the memcpy would overflow by 2 bytes if size == IPMI_MAX_MSG_LENGTH. A patch attached to limit size to (IPMI_MAX_LENGTH - 2). Cc: Corey Minyard <minyard@acm.org> Signed-off-by:

Fix the "apm: set display: Interface not engaged" error on Armada laptops again. Jordan said: I think this is fine. It seems to me that this may be the fault of one or both of the APM solutions handling this situation in a non-standard way, but since APM is used very little on the Geode, and I have direct access to our BIOS folks, if this problem comes up with a customer again, we'll solve it from the firmware.

DEBUG_MUTEX flag is on by default in current kernel configuration. During performance testing, we saw mutex debug functions like mutex_debug_check_no_locks_freed (called by kfree()) is expensive as it goes through a global list of memory areas with mutex lock and do the checking. For benchmarks such as Volanomark and Hackbench, we have seen more than 40% drop in performance on some platforms. We suggest to set DEBUG_MUTEX off by default. Or at least do that later when we feel that the mutex changes in the current code have stabilized. Signed-off-by:

There are places in the kernel where we look up files in fd tables and access the file structure without holding refereces to the file. So, we need special care to avoid the race between looking up files in the fd table and tearing down of the file in another CPU. Otherwise, one might see a NULL f_dentry or such torn down version of the file. This patch fixes those special places where such a race may happen. Signed-off-by:

We were missing __volatile__ on some bits of asm in the segfault handlers. On x86_64, this was messing up the move from %rdx to uc because that was moved to after the GET_FAULTINFO_FROM_SC, which changed %rdx. Also changed the other bit of asm and the one in the i386 handler to prevent any similar occurrences. Signed-off-by:

This modification is required to fix debugging function for m32r targets with !CONFIG_ISA_DSP_LEVEL2, by unifying 'struct pt_regs' and 'struct sigcontext' size for all M32R ISA. Some m32r processor core with !CONFIG_ISA_DSP_LEVEL2 configuration has only single accumulator a0 (ex. VDEC2 core, M32102 core, etc.), the others with CONFIG_ISA_DSP_LEVEL2 has two accumulators, a0 and a1. This means there are two variations of thread context. So far, we reduced and changed stackframe size at a syscall for their context size. However, this causes a problem that a GDB for processors with CONFIG_ISA_DSP_LEVEL2 cannot be used for processors with !CONFIG_ISA_DSP_LEVEL2. From the viewpoint of GDB support, we should reduce such variation of stackframe size for simplicity. In this patch, dummy members are added to 'struct pt_regs' and 'struct sigcontext' to adjust their size for !CONFIG_ISA_DSP_LEVEL2. This modification is also a one step for a GDB update in future. Currently, on the m32r, GDB can access process's context by using ptrace functions in a simple way of register by register access. By unifying stackframe size, we have a possibility to make use of ptrace functions of not only a single register access but also block register access, PTRACE_{GETREGS,PUTREGS}. However, for this purpose, we might have to modify stackframe structure some more; for example, PSW (processor status word) register should be pre-processed before pushing to stack at a syscall, and so on. In this case, we must update carefully both kernel and GDB at a time... Signed-off-by: -

The function free_pagedir() used by swsusp for freeing its internal data structures clears the PG_nosave and PG_nosave_free flags for each page being freed. However, during resume PG_nosave_free set means that the page in question is "unsafe" (ie. it will be overwritten in the process of restoring the saved system state from the image), so it should not be used for the image data. Therefore free_pagedir() should not clear PG_nosave_free if it's called during resume (otherwise "unsafe" pages freed by it may be used for storing the image data and the data may get corrupted later on).

for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future. This patch replaces for_each_cpu with for_each_possible_cpu. Signed-off-by:

While we can currently walk through thread groups, process groups, and sessions with just the rcu_read_lock, this opens the door to walking the entire task list. We already have all of the other RCU guarantees so there is no cost in doing this, this should be enough so that proc can stop taking the tasklist lock during readdir. prev_task was killed because it has no users, and using it will miss new tasks when doing an rcu traversal.
