2005-09-17[PATCH] uml: preserve errno in error pathsJeff Dike
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.

2005-09-17[PATCH] uml: breakpoint an arbitrary threadJeff Dike
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.

2005-09-15[PATCH] vgacon: Fix sanity checking in vgacon_resizeAntonino A. Daplas
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.

2005-09-15[ARM] 2911/1: ixp2000_reg_{read,write} accessorsLennert Buytenhek
Patch from Lennert Buytenhek This patch: - changes the ixp2000_reg_write accessor to take a 'volatile void *' instead of a 'volatile unsigned long *', which then allows passing in a u32 * as first argument without being greeted with a warning; and - adds an ixp2000_reg_read accessor. We can then use these accessors in ixp2000 code to access on-chip peripherals, instead of directly dereferencing pointers. This is for use by the ixp2000 microengine driver which was recently announced on netdev. We can't use readl/writel on the ixp2000 since it is usually run in big-endian mode, and on big-endian platforms, readl/writel perform byteswapping. A future patch will remove the readback from ixp2000_reg_write, since it's not needed to prevent erratum #66, and add manual readbacks to the places that need them (writes are not synchronous since we map in device space using XCB=101 nowadays), such as interrupt disabling and GPIO manipulation.
