linuxloader: Convert to python function

2018-08-23T16:58:59+00:00

We could do with one decent general purpose python function to query the path to the dynamic loader. Convert the shell code into python. Also correct baremetal to return "None", not musl loaders. (From OE-Core rev: 73fab4ede12d8ae31be72b5cb4ab29d7ef7dae17) Signed-off-by: Richard Purdie

classes/recipes: Use expanded BUILD_REPRODUCIBLE_BINARIES value

2018-03-12T22:06:32+00:00

Replace the occurences of BUILD_REPRODUCIBLE_BINARIES with expanded values ${BUILD_REPRODUCIBLE_BINARIES} so the variable does not need to be exported. (From OE-Core rev: 27f87bbc8395a2481ef808465a62d213a6b678ac) Signed-off-by: Juro Bystricky Signed-off-by: Richard Purdie

image-prelink.bbclass: support binary reproducibility

2017-08-15T23:03:15+00:00

Conditionally support binary reproducibility in built images. If BUILD_REPRODUCIBLE_BINARIES = 1 then: 1. Do not randomize library addresses 2. Set/export PRELINK_TIMESTAMP to a reproducible value. If REPRODUCIBLE_TIMESTAMP_ROOTFS is specified, then the value will be used. Otherwise the timestamp will be derived from the top git commit.

image-prelink: Disable for musl images

2017-08-13T08:27:38+00:00

For some reason prelink was refusing to prelink musl images but now sometimes does modify the binaries. Since musl has no support for this, such images end up broken and unable to boot. To avoid this, be explicit and only apply prelinking for libc-glibc. [YOCTO #11913] (From OE-Core rev: 5a25ed1071f0d9b7d95edcc2b5b4545f960d5f95) Signed-off-by: Richard Purdie

linuxloader/image-prelink/image-mklibs: Fix non-standard path prelinking

2016-03-07T00:11:40+00:00

Prelinking on x86-64 wasn't working out the box as it uses /lib and not /lib64 for libs. Prelink was refusing to link as the dynamic loader didn't match its idea of the right path. Passing in the --dyanmic-linker option avoids this. We can share code from image-mklibs so abstract that into a new class, linuxloader.bbclass. This does break prelinking of multilib images, I've opened a bug so we can loop back and fix that problem, the code would need to iterate the dynamic loaders (and setup ld.so.conf files for it).

insane/prelink: Handle nonstandard library paths

2016-03-07T00:11:39+00:00

Prelink contains some hardcoded assumptions about the path layout of the target system. Unfortunately if the system doesn't match, prelink doesn't work. This breaks: a) prelink of those images b) the unsafe-references-in-binaries QA test (which uses prelink-rtld) One way to work around this is to construct an ld.so.conf file which lists the library paths in question. We do this in sanity QA check and in the rootfs prelink code, being careful not to trample any existing target ld.so.conf. There is an additional problem that $LIB references in RPATHs won't be handled correctly, I've not see any system use these in reality though so this change at least improves things.

image/image-prelink/image-mklibs/sanity: Drop pointless EXPORT_FUNCTIONS

2014-04-01T22:37:01+00:00

I'm sick of seeing people adding to EXPORT_FUNCTIONS in these classes when they clearly have no idea what it does. Worse, these uses of it are all broken, the naming is incorrect and they do nothing. Lets remove them and try and preserve any remaining part of my sanity. (From OE-Core rev: 05a2fb19f722652c5d13be911b8ed45a264bbb40) Signed-off-by: Richard Purdie

image-prelink: remove hardcoded path assumptions, don't generate cache file

2011-05-17T16:06:38+00:00

Pass -N option to prelink so that no cache file is generated (obviates need for deleting it afterwards). Use symbolic names, ${sysconfdir} et al., rather than hardcoded paths. Pass explicit -c option to prelink in case ${sysconfdir} and ${sysconfdir_native} are different.
