uml: Fix which_tmpdir failure when /dev/shm is a symlink, and in other edge cases

2013-07-19T08:45:18Z

which_tmpdir did the wrong thing if /dev/shm was a symlink (e.g., to /run/shm), if there were multiple mounts on top of each other, if the mount(s) were obscured by a later mount, or if /dev/shm was a prefix of another mount point. This fixes these cases. Applies to 3.9.6. Signed-off-by: Tristan Schmelcher Signed-off-by: Richard Weinberger

um: os-linux/mem.c needs sys/stat.h

2010-06-29T22:29:32Z

The os-linux/mem.c file calls fchmod function, which is declared in sys/stat.h header file, so include it. Fixes build breakage under FC13. Signed-off-by: Liu Aleaxander Acked-by: Boaz Harrosh Cc: Jeff Dike Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

uml: improved error handling while locating temp dir

2008-02-08T17:22:43Z

* arch/um/os-Linux/mem.c (make_tempfile): Don't deref NULL upon failed malloc. * arch/um/os-Linux/mem.c (make_tempfile): Handle NULL tempdir. Don't let a long tempdir (e.g., via TMPDIR) provoke heap corruption.

uml: style fixes in arch/um/os-Linux

2008-02-08T17:22:42Z

Style changes under arch/um/os-Linux: include trimming CodingStyle fixes some printks needed severity indicators make_tempfile turns out not to be used outside of mem.c, so it is now static. Its declaration in tempfile.h is no longer needed, and tempfile.h itself is no longer needed. create_tmp_file was also made static. checkpatch moans about an EXPORT_SYMBOL in user_syms.c which is part of a macro definition - this is copying a bit of kernel infrastructure into the libc side of UML because the kernel headers can't be included there.

uml: tidy kern_util.h

2008-02-05T17:44:26Z

Tidy kern_util.h. It turns out that most of the function declarations aren't used, so they can go away. os.h no longer includes kern_util.h, so files which got it through os.h now need to include it directly. A number of other files never needed it, so these includes are deleted. The structure which was used to pass signal handlers from the kernel side to the userspace side is gone. Instead, the handlers are declared here, and used directly from libc code. This allows arch/um/os-Linux/trap.c to be deleted, with its remnants being moved to arch/um/os-Linux/skas/trap.c. arch/um/os-Linux/tty.c had its inclusions changed, and it needed some style attention, so it got tidied.
