[PATCH] uml: host VDSO fix

2007-03-01T22:53:38+00:00

This fixes a problem seen by a number of people running UML on newer host kernels. init would hang with an infinite segfault loop. It turns out that the host kernel was providing a AT_SYSINFO_EHDR of 0xffffe000, which faked UML into believing that the host VDSO page could be reused. However, AT_SYSINFO pointed into the middle of the address space, and was unmapped as a result. Because UML was providing AT_SYSINFO_EHDR and AT_SYSINFO to its own processes, these would branch to nowhere when trying to use the VDSO. The fix is to also check the location of AT_SYSINFO when deciding whether to use the host's VDSO.

[PATCH] uml makefiles sanitized

2005-09-29T15:46:26+00:00

UML makefiles sanitized: - number of generated headers reduced to 2 (from user-offsets.c and kernel-offsets.c resp.). The rest is made constant and simply includes those two. - mk_... helpers are gone now that we don't need to generate these headers - arch/um/include2 removed since everything under arch/um/include/sysdep is constant now and symlink can point straight to source tree. - dependencies seriously simplified.

[PATCH] uml: fix bogus HOST_ELF_CLASS symbol name

2005-09-21T23:16:30+00:00

Even if with a bit of misunderstanding, Al fixed this in commit 95608261dae863bc43292e6fbd946a3abd3aa49f. Well, the symbol was intended to come from userspace (it exists there on normal host), but since some hosts may miss that, using the kernel one is just as fine. However, rename it to be named consistently with the rest. Actually, he missed converting ELFCLASS32 to coming from kernel headers. For consistence, add ELFCLASS64 too.

[PATCH] bogus symbol used in arch/um/os-Linux/elf_aux.c

2005-09-08T00:17:33+00:00

elf_aux is userland code; it uses symbol (ELF_CLASS) that doesn't exist in userland headers; pulled into kernel-offsets.h, switched elf_aux to using it. Signed-off-by: Al Viro Signed-off-by: Linus Torvalds
