package/glibc: switch to downloading a tarball

2017-11-14T13:04:16+00:00

Currently, we do a full git clone of the repository, which takes quite some time, especially on slow networks. This was done like that because the initial patch was using the official repository as the source of the download, and that repository did not offer remotely-generated tarballs. But now we've switched to using a mirror on github, which does provide such a tarball, which provides faster downloads. Use that. However, the tarball from github differs from the one we were generating locally, because the paths inside are different. WE used to create a archive with paths starting with glibc-glibc-2.26-73-g4b692dfb95[...], while github does away with the git-describe prefix, and generates paths that start with just glibc-4b692dffb95[...]. The content are exactly identicall (checked with a diff), though. Update the hash accordingly. Signed-off-by: "Yann E.

toolchain: Bump ARC tools to arc-2017.09 release

2017-11-03T21:46:06+00:00

This commit finally bumps ARC tools to the most recent arc-2017.09 release version. ARC GNU tools of version arc-2017.09 bring some quite significant changes like: * Binutils v2.29 with additional ARC patches * GCC 7.1.1 with additional ARC patches * glibc 2.26 with additional ARC patches More information on this release could be found here: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2017.09-release Signed-off-by: Evgeniy Didin Cc: Alexey Brodkin Cc: arc-buildroot@synopsys.com Cc: Thomas Petazzoni Signed-off-by: Thomas Petazzoni

package/glibc: switch to using the maintenance branch

2017-10-29T14:49:58+00:00

glibc upstream has ruled against doing regular point-releases, but they do have a lot of interesting and important fixes for regressions and security. Backporting each patch, or cherry-picking individual patches is off limits for us, so we just switch to using the currently-latest HEAD of the maintenance branch instead. The version number is obtained with: $ git describe --match 'glibc-*' --abbrev=40 origin/release/2.26/master The alternative options were: - download the tarball from the git tree --> does not work; not an option - download the 2.26 tarball, and bundle the individual patches in Buildroot --> maintenance of patches is a burden; not an option - download the 2.26 tarball, maintain the list of patches to download from the git tree --> not an option for the same reason So we end up just doing a git clone. The git tree is today about ten times the size of the tarball, so a rough estimate makes it at about ten times the download time. Also upstream doesn't officially provide an https download location [1]. There is one but it's not reliable, sometimes the connection time out and end-up with a corrupted git repo: fatal: unable to access 'https://sourceware.org/git/glibc.git/': Failed to connect to sourceware.org port 443: Connection timed out So switch to using a git mirror from github which is updated once a day [2]. This allow at the same time to clone the git repository faster. Note: The glibc 2.26 patches are not kept for the arc toolchain since they are fixing an issue with the new float128 support introduced in x86, x86_64 and powerpc64le.

toolchain: add glibc support for ARCv2

2017-10-10T21:13:34+00:00

Finally there's working ARC port of glibc thanks to Vineet and Cuper! This port is based on pretty recent glibc's master branch and ARC changes are being reviewed now in glibc's mailing list. Thus we again have to use sources from our GitHub but as soon as there's a glibc release with our patches applied we'll switch to upstream releases and will drop our glibc GitHub repo alltogether. Note now we cut tags in glibc repo simultaneously with tags in Binutils and GCC repos and so to make sure everything works in the best way we plan to update glibc tag together with Binutils and GCC. Also note as of today ARCompact (AKA ARCv1 ISA) is not supported in glibc but we plan to fix it soonish so for now we make glibc intentionally dependent on archs38. Also note we are not creating directory "2.26" because all patches for glibc ver 2.26 applies to arc glibc port.

glibc: add upstream security patches fixing CVE-2017-1000366 (stack clash)

2017-06-28T21:28:47+00:00

glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt Patches are identical to upstream, except that the ChangeLog modifications have been stripped.
