The poster child for this patch is the third tuntap_user hunk. When an ioctl fails, it properly closes the opened file descriptor and returns. However, the close resets errno to 0, and the 'return errno' that follows returns 0 rather than the value that ioctl set. This caused the caller to believe that the device open succeeded and had opened file descriptor 0, which caused no end of interesting behavior. The rest of this patch is a pass through the UML sources looking for places where errno could be reset before being passed back out. A common culprit is printk, which could call write, being called before errno is returned. In some cases, where the code ends up being much smaller, I just deleted the printk. There was another case where a caller of run_helper looked at errno after a failure, rather than the return value of run_helper, which was the errno value that it wanted. Signed-off-by:

This patch implements a stack trace for a thread, not unlike sysrq-t does. The advantage to this is that a break point can be placed on showreqs, so that upon showing the stack, you jump immediately into the debugger. While sysrq-t does the same thing, sysrq-t shows *all* threads stacks. It also doesn't work right now. In the future, I thought it might be acceptable to make this show all pids stacks, but perhaps leaving well enough alone and just using sysrq-t would be okay. For now, upon receiving the stack command, UML switches context to that thread, dumps its registers, and then switches context back to the original thread. Since UML compacts all threads into one of 4 host threads, this sort of mechanism could be expanded in the future to include other debugging helpers that sysrq does not cover. Note by jdike - The main benefit to this is that it brings an arbitrary thread back into context, where it can be examined by gdb. The fact that it dumps it stack is secondary. This provides the capability to examine a sleeping thread, which has existed in tt mode, but not in skas mode until now. Also, the other threads, that sysrq doesn't cover, can be gdb-ed directly anyway. Signed-off-by: Allan Graves<allan.graves@gmail.com> Signed-off-by:

This patch moves code that is in both switch_to_tt and switch_to_skas to the top level _switch_to function, keeping us from duplicating code. It is required for the stack trace patch to work properly. Signed-off-by:

When an asynchronous interruption occurs during the execution of the 'critical section' within the generic interruption handling code (entry.S), a faulty check for a userspace PSW may result in a corrupted kernel stack pointer which subsequently triggers a stack overflow check. Signed-off-by:

Make sure we that completion is the final action we take; prior to this change, another CPU may have changed ap->pio_task_state before we tested it a final time. Spotted by, and original patch by Albert Lee @ IBM. Also includes a minor optimization: eliminate a ton of unnecessary queue_work() calls, simply by jumping to the beginning of the FSM function ata_pio_task().

Reported by: walt <wa1ter@myrealbox.com> "I routinely switch the console font during bootup to 8x8 so I can get 50 lines per screen. Until 09 Sept, just changing to the small font automatically gave me all 50 lines -- but now I'm only getting 25 lines even with the small font. The bottom half of the screen displays the text that already scrolled off the top." This bug is due to an erroneous check in the recently added hook, vgacon_resize(). It checks the new height against the original number of rows of the console. Because the original number of rows depends on both the scanline and the font height, check it instead against the scanline/fontheight. Signed-off-by:

Thomas Gleixner reported that mmaping and unmapping each physical page in turn eventually caused the kernel to oops. It appears that pfn_valid() in the discontigmem case was too simplistic for proper operation. Tighten the logic so we also check if the PFN is within the range of the selected memory node.
