2008-01-30x86 vDSO: i386 vdso32Roland McGrath13-139/+37
This makes the i386 kernel use the new vDSO build in arch/x86/vdso/vdso32/ to replace the old one from arch/x86/kernel/.

2008-01-30x86 vDSO: vdso32 buildRoland McGrath2-3/+112
This builds the 32-bit vDSO images in the arch/x86/vdso subdirectory. Nothing uses the images yet, but this paves the way for consolidating the vDSO build logic all in one place. The new images use a linker script sharing the layout parts from vdso-layout.lds.S with the 64-bit vDSO. A new vdso32-syms.lds is generated in the style of vdso-syms.lds.

This moves the i386 vDSO sources into arch/x86/vdso/vdso32/, a new directory. This patch is a pure renaming, but paves the way for consolidating the vDSO build logic.

2008-01-30x86 vDSO: harmonize asm-offsetsRoland McGrath2-37/+37
This change harmonizes the asm-offsets macros used in the 32-bit vDSO across 32-bit and 64-bit builds. It's a purely cosmetic change for now, but it paves the way for consolidating the 32-bit vDSO builds.

2008-01-30x86 vDSO: new layoutRoland McGrath3-78/+89
This revamps the vDSO linker script to lay things out with the best packing of the data and good, separate alignment of the code. The rigid layout using VDSO_TEXT_OFFSET no longer matters to the kernel. I've moved the layout parts of the linker script into a new include file, vdso-layout.lds.S; this is in preparation for sharing the script for the 32-bit vDSO builds too.

2008-01-30x86 vDSO: use vdso-syms.ldsRoland McGrath4-15/+22
This patch changes the kernel's references to addresses in the vDSO image to be based on the symbols defined by vdso-syms.lds instead of the old vdso-syms.o symbols. This is all wrapped up in a macro defined by the new asm-x86/vdso.h header; that's the only place in the kernel source that has to know the details of the scheme for getting vDSO symbol values.

2008-01-30x86 vDSO: generate vdso-syms.ldsRoland McGrath2-0/+24
This patch adds a new way of extracting symbols from the built vDSO image. This is much simpler and less fragile than using ld -R; it removes the need to control the DSO layout quite so exactly. I was clearly unduly distracted by clever ld uses when I did the original vDSO implementation.

2008-01-30x86: randomize brkJiri Kosina5-1/+25
Randomize the location of the heap (brk) for i386 and x86_64. The range is randomized in the range starting at current brk location up to 0x02000000 offset for both architectures. This, together with pie-executable-randomization.patch and pie-executable-randomization-fix.patch, should make the address space randomization on i386 and x86_64 complete. Arjan says: This is known to break older versions of some emacs variants, whose dumper code assumed that the last variable declared in the program is equal to the start of the dynamically allocated memory region. (The dumper is the code where emacs effectively dumps core at the end of it's compilation stage; this coredump is then loaded as the main program during normal use) iirc this was 5 years or so; we found this way back when I was at RH and we first did the security stuff there (including this brk randomization). It wasn't all variants of emacs, and it got fixed as a result (I vaguely remember that emacs already had code to deal with it for other archs/oses, just ifdeffed wrongly). It's a rare and wrong assumption as a general thing, just on x86 it mostly happened to be true (but to be honest, it'll break too if gcc does something fancy or if the linker does a non-standard order). Still its something we should at least document. Note 2: afaik it only broke the emacs *build*. I'm not 100% sure about that (it IS 5 years ago) though.

2008-01-30x86: remove -maccumulate-outgoing-args on 32-bitAdrian Bunk1-4/+0
Contrary to the comment "newer gccs do it by default", newer gcc versions default to -maccumulate-outgoing-args only with CONFIG_CC_OPTIMIZE_FOR_SIZE=n, and then only with some CPU settings. Measured with an i386 defconfig, gcc 4.2.1 and kernel 2.6.23-rc1 ("orig" is the plain kernel, "changed is with -maccumulate-outgoing-args removed): $ ls -la vmlinux* -rwxrwxr-x 1 bunk bunk 6269713 2007-07-24 22:19 vmlinux.changed -rwxrwxr-x 1 bunk bunk 6425361 2007-07-24 22:19 vmlinux.orig $ size vmlinux.* text data bss dec hex filename 4493465 504108 614400 5611973 55a1c5 vmlinux.changed 4646160 504108 614400 5764668 57f63c vmlinux.orig $ That's a 2.5% size increase that does for sure hurt small systems. If the stack unwinder ever comes back and needs this as indicated in the comment, adding it to the cflags when the user enabled the unwinder should be a better option.

2008-01-30x86: remove extern declarations for code, data, bss resourcesBernhard Walle7-121/+127
This patch removes the extern struct resource declarations for data_resource, code_resource and bss_resource on x86 and declares that three structures as static as done on other architectures like IA64. On i386, these structures are moved to setup_32.c (from e820_32.c) because that's code that is not specific to e820 and also required on EFI systems. That makes the "extern" reference superfluous. On x86_64, data_resource, code_resource and bss_resource are passed to e820_reserve_resources() as arguments just as done on i386 and IA64. That also avoids the "extern" reference and it's possible to make it static.
