um: Fix kcov crash during startup

2019-07-02T21:27:42+00:00

Kcov fails to start when compiled with kcov. Disable KCOV on arch/uml/kernel/skas. $ gdb -q -ex r ./vmlinux Program received signal SIGSEGV, Segmentation fault. check_kcov_mode (t=<>, needed_mode=<>) at kernel/kcov.c:70 70 mode = READ_ONCE(t->kcov_mode); Signed-off-by: Marek Majkowski Signed-off-by: Richard Weinberger

uml: style fixes pass 3

2007-10-16T16:43:05+00:00

Formatting changes in the files which have been changed in the course of folding foo_skas functions into their callers. These include: copyright updates header file trimming style fixes adding severity to printks These changes should be entirely non-functional.

uml: remove code made redundant by CHOOSE_MODE removal

2007-10-16T16:43:05+00:00

This patch makes a number of simplifications enabled by the removal of CHOOSE_MODE. There were lots of functions that looked like int foo(args){ foo_skas(args); } The bodies of foo_skas are now folded into foo, and their declarations (and sometimes entire header files) are deleted. In addition, the union uml_pt_regs, which was a union between the tt and skas register formats, is now a struct, with the tt-mode arm of the union being removed. It turns out that usr2_handler was unused, so it is gone. Signed-off-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] uml: file renaming

2006-09-27T15:26:16+00:00

Move some foo_kern.c files to foo.c now that the old foo.c files are out of the way. Also cleaned up some whitespace and an emacs formatting comment. Signed-off-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] uml: cleanup unprofile expression and build infrastructure

2006-05-02T01:17:45+00:00

*) Rather than duplicate in various buggy ways the application of CFLAGS_NO_HARDENING and UNPROFILE (which apply to the same files), centralize it in Makefile.rules. UNPROFILE_OBJS mustn't be listed in USER_OBJS but are compiled as such. I've also verified that unprofile didn't work in the current form, because we set _c_flags directly (using CFLAGS and not USER_CFLAGS, which is wrong), which is normally used by c_flags, but we also override c_flags for all USER_OBJS, and there we don't call unprofile. Instead it only worked for unmap.o, the only one which wasn't a USER_OBJ. We need to set c_flags (which is not a public Kbuild API) to clear a lot of compilation flags like -nostdinc which Kbuild forces on everything. *) Rather than $(CFLAGS_$(notdir $@)), which expands to CFLAGS_anObj.s when building "anObj.s", use $(CFLAGS_$(*F).o) which always accesses CFLAGS_anObj.o, like done by Kbuild. *) Make c_flags apply to all targets having the same basename, rather than listing .s, .i, .lst and .o, with the use (which I tested) of $(USER_OBJS:.o=.%): c_flags = ... and of - $(obj)/unmap.c: _c_flags = ... + $(obj)/unmap.%: _c_flags = ...

[PATCH] uml: fix compilation and execution with hardened GCC

2006-05-02T01:17:45+00:00

To make some half-assembly stubs compile, disable various "hardened" GCC features: *) we can't make it build PIC code as we need %ebx to do syscalls and GCC wants it free for PIC *) we can't leave stack protection as the stub is moved (not relocated!) in memory so the RIP-relative access to the canary tries reading from an unmapped address and causes a segfault, since we move the stub of various megabytes (the exact amount will be decided at runtime) away from the link-time address.
