This series makes me sad. It brings the 64-bit vdso back above 4kB,
like it was in 3.15. It's also just silly, but it seems to be
needed to keep binutils happy when debugging the vdso.
Patch 5 isn't really necessary, and is likely not 3.16 material.
It's useful for testing the rest of this series, though.
Andy Lutomirski (5):
x86,vdso: Discard the __bug_table section
x86,vdso2c: Use better macros for ELF bitness
x86,vdso: Improve the fake section headers
x86,vdso: Remove some redundant in-memory section headers
x86,vdso: Create .build-id links for unstripped vdso files

Can you tell me what version of ld you're using and send me the output of: for i in arch/x86/vdso/*.so.dbg; do echo $i; eu-readelf -S $i; done To summarize, the issue is that, in 3.16, the vvar area is accessed in a PC-relative manner from the vdso code. So we have: vdso page 1 | vdso page 2 | vvar page 1 | vvar page 2 (where the number of vdso pages can vary) The difficulty comes from the fact that a decent amount of userspace code wants the vdso to have some section headers, and linkers don't stick section headers into allocatable sections, since section headers were never intended to be memory mapped. So there's a risk that the section headers dangle off the last loadable page in the vdso, at which point they overlap the vvar area. I've seen this happen. The "solution" in tip is to move the section headers into a real allocatable area reserved for that purpose. The error you're seeing is that I didn't allocate enough space for all the allocatable section headers. This crap almost makes me want to go back to something closer to Stefani's implementation of sticking vvar before the vdso so we can safely leave non-allocatable crap dangling off the end of the vdso. I don't really want to play section header whack-a-mole. We could also just give up on space efficiency and allocate space for several extra section headers (and their associated names!). --Andy ^ permalink raw reply [flat|nested] 31+ messages in thread

I think we want to actually print the number that we are trying to copy in addition to the maximum, and I also noticed the test looks wrong.

Peter Anvin Cc: Ingo Molnar, linux-kernel, Thomas Gleixner, linux-tip-commits, Andy Lutomirski vdso2c was checking for various types of relocations to detect when the vdso had undefined symbols or was otherwise dependent on relocation at load time. Undefined symbols in the vdso would fail if accessed at runtime, and certain implementation errors (e.g. branch profiling or incorrect symbol visibilities) could result in data access through the GOT that requires relocations. This could be as simple as: extern char foo; return foo; Without some kind of visibility control, the compiler would assume that foo could be interposed at load time and would generate a relocation. My toolchain emits explicit-addent (RELA) instead of implicit-addent (REL) relocations for data access, and vdso2c forgot to detect those. Whether these bad relocations would actually fail at runtime depends on what the linker sticks in the unrelocated references. Nonetheless, these relocations have no business existing in the vDSO and should be fixed rather than silently ignored. This error could trigger on some configurations due to branch profiling.

Peter Anvin Cc: Linux-Kernel@Vger. Kernel. Org, Andy Lutomirski Fully stripping the vDSO has other unfortunate side effects: - binutils is unable to find ELF notes without a SHT_NOTE section. - Even elfutils has trouble: it can find ELF notes without a section table at all, but if a section table is present, it won't look for PT_NOTE. - gdb wants section names to match between stripped DSOs and their symbols; otherwise it will corrupt symbol addresses. We're also breaking the rules: section 0 is supposed to be SHT_NULL. Fix these problems by building a better fake section table. While we're at it, we might as well let buggy Go versions keep working well by giving the SHT_DYNSYM entry the correct size. This is a bit unfortunate: it adds quite a bit of size to the vdso image. If/when binutils improves and the improved versions become widespread, it would be worth considering dropping most of this.

Peter Anvin <hpa@linux.intel.com> CommitDate: Thu, 19 Jun 2014 15:45:12 -0700 x86/vdso: Improve the fake section headers Fully stripping the vDSO has other unfortunate side effects: - binutils is unable to find ELF notes without a SHT_NOTE section. - Even elfutils has trouble: it can find ELF notes without a section table at all, but if a section table is present, it won't look for PT_NOTE. - gdb wants section names to match between stripped DSOs and their symbols; otherwise it will corrupt symbol addresses. We're also breaking the rules: section 0 is supposed to be SHT_NULL. Fix these problems by building a better fake section table. While we're at it, we might as well let buggy Go versions keep working well by giving the SHT_DYNSYM entry the correct size. This is a bit unfortunate: it adds quite a bit of size to the vdso image. If/when binutils improves and the improved versions become widespread, it would be worth considering dropping most of this.

While we're at it, rather than aligning the actual executable text, just shove some unused-at-runtime data in between real data and text. My vdso image is still above 4k, but I'm disinclined to try to trim it harder for 3.16. For future trimming, I suspect that these sections could be moved to later in the file and dropped from the in-memory image: .gnu.version and .gnu.version_d (this may lose versions in gdb) .eh_frame (should be harmless) .eh_frame_hdr (I'm not really sure) .hash (AFAIK nothing needs this section header) Signed-off-by: Andy Lutomirski <luto@amacapital.net> Link: http://lkml.kernel.org/r/2e96d0c49016ea6d026a614ae645e93edd325961.1403129369.git.luto@amacapital.net Signed-off-by: H.

Org, Andy Lutomirski With this change, doing 'make vdso_install' and telling gdb: set debug-file-directory /lib/modules/KVER/vdso will enable vdso debugging with symbols. This is useful for testing, but kernel RPM builds will probably want to manually delete these symlinks or otherwise do something sensible when they strip the vdso/*.so files. This may break make vdso_install with binutils before 2.17.50.0.17. On the other hand, make vdso_install was probably never useful with earlier binutils, since the installed files are AFAIK completely useless without build-id.

If --build-id=none on modern binutils accurately replicates old binutils, it fails by silently creating a broken symlink called .debug. If you want this patch for 3.16, I can send a better version that just doesn't create the links on old binutils. > > -hpa > > -- Andy Lutomirski AMA Capital Management, LLC ^ permalink raw reply [flat|nested] 31+ messages in thread
