Queueing to receive an ISO packet with a payload length of zero silently does nothing in dualbuffer mode, and crashes the kernel in packet-per-buffer mode. Return an error in dualbuffer mode, because the DMA controller won't let us do what we want, and work correctly in packet-per-buffer mode. Signed-off-by:

This patch fixes 2 edge cases in using kgdb in conjunction with gdb. 1) kgdb_deactivate_sw_breakpoints() should process the entire array of breakpoints. The failure to do so results in breakpoints that you cannot remove, because a break point can only be removed if its state flag is set to BP_SET. The easy way to duplicate this problem is to plant a break point in a kernel module and then unload the kernel module. 2) kgdb_activate_sw_breakpoints() should process the entire array of breakpoints. The failure to do so results in missed breakpoints when a breakpoint cannot be activated. Signed-off-by:

On some architectures for the segv trap, gdb wants to pass the signal back on continue. For kgdb this is not the default behavior, because it can cause the kernel to crash if you arbitrarily pass back a exception outside of kgdb. Instead of causing instability, pass a message back to gdb about the supported kgdb signal passing and execute a standard kgdb continue operation. Signed-off-by:

On an SMP system the kgdb_single_step flag has the possibility to indefinitely hang the system in the case. Consider the case where, CPU 1 has the schedule lock and CPU 0 is set to single step, there is no way for CPU 0 to run another task. The easy way to observe the problem is to make 2 cpus busy, and run the kgdb test suite. You will see that it hangs the system very quickly. while [ 1 ] ; do find /proc > /dev/null 2>&1 ; done & while [ 1 ] ; do find /proc > /dev/null 2>&1 ; done & echo V1 > /sys/module/kgdbts/parameters/kgdbts The side effect of this patch is that there is the possibility to miss a breakpoint in the case that a single step operation was executed to step over a breakpoint in common code. The trade off of the missed breakpoint is preferred to hanging the kernel. This can be fixed in the future by using kprobes or another strategy to step over planted breakpoints with out of line execution. CC: Ingo Molnar <mingo@elte.hu> Signed-off-by:

The kgdb core should not assume that a single step operation of a kernel thread will complete on the same CPU. The single step flag is set at the "thread" level and it is possible in a multi cpu system that a kernel thread can get scheduled on another cpu the next time it is run. As a further safety net in case a slave cpu is hung, the debug master cpu will try 100 times before giving up and assuming control of the slave cpus is no longer possible. It is more useful to be able to get some information out of kgdb instead of spinning forever. Signed-off-by:

It is possible for the user_mode_vm(regs) check to return true on the i368 arch for a non master kgdb cpu or when the master kgdb cpu handles the NMI watch dog exception. The solution is simply to select the correct gdb_ss location based on the check to user_mode_vm(regs). CC: Ingo Molnar <mingo@elte.hu> Acked-by:

Some versions of gcc replace calls to strstr() with single-character "needle" string parameters by calls to strchr() behind our back. This causes linking errors if strchr() is defined as an inline function in <asm/string.h> (e.g. on m68k, which BTW doesn't have kgdb support). Prevent this by explicitly calling strchr() instead.

Roel Kluin reported an error found with Parfait. Where we want to ensure that that kgdb_info[-1] never gets accessed. Also check to ensure any negative tid does not exceed the size of the shadow CPU array, else report critical debug context because it is an internal kgdb failure. Reported-by:

The comment in there used to be true, but these days do_brk() does the arch-specific check that covers what we open-coded here. So we can use sys_brk() just fine, only need to do force_successful_syscall_return() after it. See commit 3a459756 - that's when the checks in do_brk() had been originally added. Acked-by:

We've had TASK_SIZE set to 1<<31 for 31bit tasks since May 2004. Before that old32_mmap() had to deal with do_mmap_pgoff() giving it an address out of range. It had tried to do that by checking return value and doing do_munmap() (at wrong address, BTW). IOW, that code had been dead for 5.5 years (and bogus - for 8). Kill. Acked-by:

This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA. This driver is a KMS-based driver and requires a compatible nouveau userspace libdrm and nouveau X.org driver. This driver requires firmware files not available in this kernel tree, interested parties can find them via the nouveau project git archive. This driver is reverse engineered, and is in no way supported by nVidia. Support for nearly the complete range of nvidia hw from nv04->g80 (nv50) is available, and the kms driver should support driving nearly all output types (displayport is under development still) along with supporting suspend/resume. This work is all from the upstream nouveau project found at nouveau.freedesktop.org.
