Pull debugfs patches from Al Viro: "debugfs patches, mostly to make it possible for something like tracefs to be transparently automounted on given directory in debugfs. New primitive in there is debugfs_create_automount(name, parent, func, arg), which creates a directory and makes its ->d_automount() return func(arg). Another missing primitive was debugfs_create_file_size() - open-coded in quite a few places. Dave's patch adds it and converts the open-code instances to calling it" * 'debugfs_automount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: debugfs: Provide a file creation function that also takes an initial size new primitive: debugfs_create_automount() debugfs: split end_creating() into success and failure cases debugfs: take mode-dependent parts of debugfs_get_inode() into callers fold debugfs_mknod() into callers fold debugfs_create() into caller fold debugfs_mkdir() into caller debugfs_mknod(): get rid useless arguments fold debugfs_link() into caller debugfs: kill __create_file() debugfs: split the beginning and the end of __create_file() off debugfs_{mkdir,create,link}(): get rid of redundant argument

While reporting the (refreshed) list of modules on automatic updates we may hit the page boundary of the output console and cause a stop if pagination is enabled. However, gdb does not accept user input while running over the breakpoint handler. So we get stuck, and the user is forced to interrupt gdb. Resolve this by disabling pagination during automatic symbol updates. We restore the user's configuration once done.

I tried to use these scripts in an ubuntu 14.04 host (gdb 7.7 compiled against python 3.3) but there were several errors. I believe this patch fixes these issues so that the commands now work (I tested lx-symbols, lx-dmesg, lx-lsmod). Main issues that needed to be resolved: * In python 2 iterators have a "next()" method. In python 3 it is __next__() instead (so let's just add both). * In older python versions there was an implicit conversion in object.__format__() (used when an object is in string.format()) where it was converting the object to str first and then calling str's __format__(). This has now been removed so we must explicitly convert to str the objects for which we need to keep this behavior. * In dmesg.py: in python 3 log_buf is now a "memoryview" object which needs to be converted to a string in order to use string methods like "splitlines()". Luckily memoryview exists in python 2.7.6 as well, so we can convert log_buf to memoryview and use the same code in both python 2 and python 3. This version of the patch has now been tested with gdb 7.7 and both python 3.4 and python 2.7.6 (I think asking for at least python 2.7.6 is a reasonable requirement instead of complicating the code with version checks etc).

This is probably the most useful helper when debugging kernel modules: lx-symbols first reloads vmlinux. Then it searches recursively for *.ko files in the specified paths and the current directory. Finally it walks the kernel's module list, issuing the necessary add-symbol-file command for each loaded module so that gdb knows which module symbol corresponds to which address. It also looks up variable sections (bss, data, rodata) and appends their address to the add-symbole-file command line. This allows to access global module variables just like any other variable.

This provides the basic infrastructure to load kernel-specific python helper scripts when debugging the kernel in gdb. The loading mechanism is based on gdb loading for <objfile>-gdb.py when opening <objfile>. Therefore, this places a corresponding link to the main helper script into the output directory that contains vmlinux. The main scripts will pull in submodules containing Linux specific gdb commands and functions. To avoid polluting the source directory with compiled python modules, we link to them from the object directory. Due to gdb.parse_and_eval and string redirection for gdb.execute, we depend on gdb >= 7.2. This feature is enabled via CONFIG_GDB_SCRIPTS.
