This fixes coverity bug id #473. After the for loop i==16 if we didn't find a cdrom. So we should check for i==16 first before checking the array element. Signed-off-by:

This fixes coverity bug id #469. The out of range check didnt work as intended, as seen by the printk(), which states that boardno has to be 1 <= boardno <= MAX_BOARD. Signed-off-by:

We must disable local IRQs while holding KM_IRQ0 or KM_IRQ1. Otherwise, an IRQ handler could use those kmap slots while this code is using them, resulting in memory corruption.

The event handler mechanism in the IPMI driver had a limit on the number of received events, but the counts were not being updated. Update the counts to impose a limit. This is not a critical fix, as this function (the sending of the events) has to be turned on by the user, anyway. This avoids problems if they forget to turn it back off. Signed-off-by:

The spufs file system creates files in a directory before instantiating the directory itself, which causes a NULL pointer access in inotify_d_instantiate since c32ccd87. I'd like to keep this behavior since it means that the user will not have access to files in the directory before I know that I succeed in creating everything in it. This patch adds a simple check for the inode to keep that working. Signed-off-by:

Everybody seems to be using /proc/vmcore as a method to access the kernel crash dump. Hence probably it makes sense to enable CONFIG_PROC_VMCORE by default if CONFIG_CRASH_DUMP is selected. This makes kdump configuration further easier for a user. Signed-off-by:

Paolo 'Blaisorblade' Giarrusso authored
An UML user reported (against 2.6.13.3/UML) he got kernel Oopses when trying to rmmod (on a kernel with module unloading enabled) a module compiled with module unloading disabled. As crashing is a very correct thing to do in that case, a solution is altering the vermagic string to include this too. Possibly, however, the code should not crash in this case, even if the module didn't support unloading - it should simply abort the module removal. In this case, fixing that bug would be a better solution. I've not investigated though. (akpm: a bit marginal - root screwed up and shot himself in the foot).

Remove an unnecessary memory barrier (implicit in rcu_dereference()) from install_session_keyring(). install_session_keyring() is also rearranged a little to make it slightly more efficient. As install_*_keyring() may schedule (in synchronize_rcu() or keyring_alloc()), they may not be entered with interrupts disabled - and so there's no point saving the interrupt disablement state over the critical section. exec_keys() will also be invoked with interrupts enabled, and so that doesn't need to save the interrupt state either.

In the memory barrier document, improve the example of the data dependency barrier situation by: (1) showing the initial values of the variables involved; and (2) repeating the instruction sequence description, this time with the data dependency barrier actually shown to make it clear what the revised sequence actually is.

David Howells authored
Fix the memory barrier documentation to attempt to describe atomic ops correctly. atomic_t ops that return a value _do_ imply smp_mb() either side, and so don't actually require smp_mb__*_atomic_*() special barriers. Also explains why special barriers exist in addition to normal barriers. Further fix the memory barrier documents to portray bitwise operation memory barrier effects correctly following Nick Piggin's comments. It makes the point that any atomic op that both modifies some state in memory and returns information on that state implies memory barriers on both sides. Signed-off-by:

The MPBL0010 Telco clock driver (drivers/char/tlclk.c) uses 0222 (anyone can write) permissions on its writable sysfs entries. Alter the permissions to 0220 (owner and group can write). The use case for this driver is to configure the fail over behavior of the clock hardware. That should be done by the more privileged users. Signed-off-by:

Remove dead code from tty_io.c release_dev() Signed-off-by:

Paul Fulghum authored
Remove duplicate call to idr_remove() in ptmx_open. Error during open can result in call to release_dev() followed by call to idr_remove(). release_dev already calls idr_remove so the second call can cause a stack dump in idr_remove()->sub_remove() flagging an attempt to release an already released entry. I reproduces this on a machine with a misconfigured X server (attempting to restart multiple times rapidly) getting the same error as the 1st link below. This also seems to be related to: http://marc.theaimsgroup.com/?l=selinux&m=110536513426735&w=2 http://marc.theaimsgroup.com/?l=selinux&m=110596994916785&w=2 The stack dump can occur on close (as well as open) as shown in the 1st instance above, possible from something like: process A - open (index=0), open fail to out1, release_dev calls idr_remove (index 0), down(sem) sleeps process B - open (index=0), open OK (idr allocated) process A - wake and call idr_remove on index 0 ... process B - close, release_dev, stack dump on idr_remove (index=0) because entry already removed Signed-off-by:

Remove the blkmtd driver. - An alternative exists (block2mtd) that hasn't had bug report for > 1 year. - Most embedded people tend to use ancient kernels with custom patches from mtd cvs and elsewhere, so the 1 year warning period neither helps nor hurts them too much. - It's in the way of klibc. The problems caused by pulling blkmtd support are fairly low, while the problems caused by delaying klibc can be fairly substantial. At best, this would be a severe burden on hpa's time.

The only record we have of the real-time age of a process, regardless of execs it's done, is start_time. When a non-leader thread exec, the original start_time of the process is lost. Things looking at the real-time age of the process are fooled, for example the process accounting record when the process finally dies. This change makes the oldest start_time stick around with the process after a non-leader exec. This way the association between PID and start_time is kept constant, which seems correct to me.

If SELECT_STACK_ALLOC is not a multiple of sizeof(long) then stack_fds[] would be shorter than SELECT_STACK_ALLOC bytes and could overflow later in the function. Fixed by simply rearranging the test later to work on sizeof(stack_fds) Currently SELECT_STACK_ALLOC is 256 so this doesn't happen, but it's nasty to have things like this hidden in the code. What if later someone decides to change SELECT_STACK_ALLOC to 300? Signed-off-by:
