The move is nececcessary if we are doing the decompression in place. Without a move it is hard to tell if there are going to be overlapping address problems. The move is cheap so there is no apparent reason to optimize it away. Eric ^ permalink raw reply [flat|nested] 34+ messages in thread

Interesting. I have been out of the loop for a bit and had not noticed the ELF payload change. It is really sad to say that I have missed a feature like that for 4 years. Time wise copying the kernel probably takes a millisecond or less on modern hardware, so I don't think it is a particularly large concern. Looking at parse_elf I see two misfeatures. - parse_elf is short some memsets for the ELF sections that are larger in memory than they are in the file data. - We don't return the entry point of the elf header and instead hard code the beginning of the file data. The oddest thing about parse_elf is what makes the copies parse_elf performs safe. It just happens to be the case that because of the way ld lays out the file those copies turn into a single memmove that just strips off the elf header and program header. So it should be trivial to and perhaps even safer to decompress the program segments to their final destination. Looking at the way the code is evolving, I suspect we should just give up overlapping compressed data and uncompressed data. The elf header logic in theory allows the code in a more arbitrary order, and it doesn't look like anyone has done a worst case space analysis for anything except gzip. The code works most of the time today but I do wonder if it is safe. Additionally at the rate we are adding compression algorithms I don't believe that all of the compression alorigthms use the gzip footer that reports the uncompressed length of the file. So I suspect it would be wise to get z_output_len from simply examining the uncompressed file that we feed to compression programs, aka vmlinux.bin.all-y Perhaps I am wrong but I have the strongest feeling we are playing with fire and getting very lucky right now.

I think it might be even worse; on x86-64 we produce 2 MiB of completely useless zero-padding after the header. I have wanted to get rid of it but I'm not sure if the ELF code is robust enough. The code is a hackwork and yes, should be replaced by decompressing into the designated target areas. -hpa -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel.

Fair enough. But ugh. Can you point me at your config? Can you tell me your linker version? I tested this originally on both x86_64 and i386, and it worked both places for me. I want to stair at that failure mode. I am wondering what happened in your configuration that is different from mine. Perhaps a linker bug? A subtle conflict with something else? The patch didn't do anything that should have affectected per cpu sections... Eric ^ permalink raw reply [flat|nested] 34+ messages in thread

Well I see what is going on now. In the vmlinux the paddrs and the poffsests stop tracking when they come to the percpu PT_LOAD segment. It looks like we give the percpu segment a 4K alignment in memory and a 2M alignment in the file. It looks like something is causing ld to compute an unfortunate physical load address for the percpu section. At first glace I would say that is a bug. Either we need the alignment or we don't. But if we need the alignment we certainly need it to be respected for the real memory locations of the init symbols.. Ugh. Eric ^ permalink raw reply [flat|nested] 34+ messages in thread

Grumble Grumble. If I force a 2M alignment, poffsets and paddrs align and my previous patches work. Although I don't expect that to be more than a testing hack. Meanwhile if I force a 4K max page size for most purposes things look better from a file offset perspective. But the data segment is now less aligned in the file than it is in memory and my patches don't work. Sigh. I feel like I have stumbled into pandoras box.

Sort of. It was my premise that we should not need a general PHDR parser, or even a parser at all , especially since a general PHDR parser is hard to fit into the existing bzImage protocol. So far emperically except when dealing with the weird percpu section we don't need a general PHDR parser. There is just enough weirdness that it makes sense to have a phdr parser that just verifies it doesn't need to do anything. So I have tracked down part of the crazyness. CONFIG_RODATA actually uses 2MB alignment, making -z max_page_size=4096 a bit questionable. In practice I'm not concerned with a few extra zero's in the file because giant runs of zeros compress very well. I am going to play with the percpu section a bit more and see if I can remove the need for magic to get it's p_offset and p_paddr to be aligned in the file, as that comes for free with everything else. Hmm. I think I see why the percpu section is problematic. We have to specify AT on all of our sections and the usual formula is ".section : AT(.section - LOAD_OFFSET)". Unfortunately that doesn't work when we we set the virtual address to zero. I will play with it a little more and see if I can come up with something interesting.

Questionable as in the current elf loader in misc.c relies on the fact that there is an almost a fixed offset between physical addresses and file offsets for all of the PT_LOAD segments in the Elf header. In fact CONFIG_RODATA && CONFIG_X86_64 && CONFIG_SMP in combination with -z max_page_size=4096 fails to boot. The Elf loader in misc.c starts coping from lower addresses to higher addresses, instead of higher addresses to lower and that fails miserably. But -z max_page_size=4096 is not the problem the ELF loader is. Eric ^ permalink raw reply [flat|nested] 34+ messages in thread

Peter Anvin; +Cc: Tejun Heo, hacklu, linux-kernel Create a space for the elf headers at the begginng of the kernels image in memory. - Rework arch/x86/kernel/vmlinux.lds.S so that we allow room for the ELF header in the loaded image. This removes the need in the ELF executalbe to insert padding between the ELf headers and the data of the first program segment. This reduces the size of vmlinux by 2MB on x86_64. This removes an overlap of the ELF header and kernel text in arch/x86/boot/compressed that required code to moved. - Move the symbol _text outside of the .text section, and add the fixups in relocs.c to add relocations against _text. This allows the symbol _text to come before the ELF header and effectively including the ELF header in the text section. If this isn't done _text moves 344 bytes in memory on x86_64 and creates subtle breakage in routines like cleanup_highmap, which assume _text is at the beginning of the kernels memory and that _text is 4K+ aligned. The current usage of the symbol _text is already that _text specifies the beginning of the kernel's memory and that _stext specifies where the kernel's code actually starts. Signed-off-by: Eric W.

Biederman @ 2012-07-09 6:55 UTC (permalink / raw) To: H. Peter Anvin; +Cc: Tejun Heo, hacklu, linux-kernel The ELF loader in arch/x86/boot/compressed/misc.c is extremely fragile, as it copies the ELF executable over itself to put the code and data in their proper place. Squeezing unneeded space out of vmlinux by passing -z max-page-size 4096 to ld was enough to render the kernel unbootable. I explored creating a flush function for our current crop of kernel decompressors. While that works it has the very unfortunate side effect of needing a much larger BOOT_HEAP_SIZE. A couple of our supported decompressors in that mode malloc 32MB for use during decompression. The other solution is to return to the original design where we created a file known as vmlinux.bin with exactly what we wanted in memory and compressed that. At this point in time there are complications to going back to the original design. - We need to preserve the ELF headers inside the compresed image file for Xen and other interesting bootloaders that open up the bzImage and boot the ELF executable contained inside. - ld will not uniformly produce a file where the file offsets have a constant offset from the in memory addresses. In particular combinations of CONFIG_RODATA and CLONFIG_x86_64 && CONFIG_SMP play games with 2MB alignments and the virtual address of functions that cause ld to emit valid ELF executables that do not have a fixed differents betwen file offset and loaded physical address making the ELF executable something that must be procecessed to get an in memory image. - The old solution to creating a memory image objcopy -O binary comes very close but it always strips the ELF header even when the ELF header is explicitly made part of the ELF file. Since all of the prebuilt tools don't work I have written a small program mkelfbin, that generates a memory image by loading an ELF executable into an in memory array. Then the ELF program headers offset fields are adjusted to reflect where in the memory image each program header is referring to. By design this results in program headers with a fixes offset between the file offset and the physical memory address with the file be loaded in memory. With the compressed data being a proper memory image misc.c no longer needs an ELF loader or dangerous copies over itself so those are removed. The result is a simpler more robust boot process, that still retains all of the modern bells and whistles. Signed-off-by: "Eric W.

Peter Anvin; +Cc: Tejun Heo, hacklu, linux-kernel By default ld uses 2MB pages and aligns our 3 program segments in the file on 2MB boundaries, creating unnecessarily large uncompressed vmlinux files. Solve this by passing -z max-page-size 4096 to ld. In my test x86_64 SMP test configuration with CONFIG_DEBUG_RODATA enabled, this reduces the size of vmlinux by roughly 5MB from 15141772 bytes to 10210188 bytes. Signed-off-by: "Eric W.

I don't think the .data..percpu section needs 2M alignment. The percpu data section is only used as init template and actual percpu addresses always go through offsetting against __per_cpu_offset[] - no matter what the vaddrs in the vmlinux are, they get offsetted into 2M aligned linear address if necessary. I think the only alignment .data..percpu needs is cacheline alignment for separating its subsections. Thanks. -- tejun ^ permalink raw reply [flat|nested] 34+ messages in thread

Of course all that changed was where in the vmlinux file not where in physical memory the data was loaded, so problems would really surprise me.
