Richard Purdie	5c928099ed	dwarfsrcfiles: Avoid races over debug-link files ... We use dwarfsrcfiles in package.bbclass to list the source files used by a binary. This is done before they're stripped and linked to debug symbols in separate files. It is possible a binary may already have a link to separate debug symbols, e.g. some of the test binaries in lttng-tools ptest. In those cases, the linked binary may be changed by package.bbclass code whilst dwarfsrcfiles is reading it. That would result in a rare SIGBUS race causing the binary to fail. To avoid this, break the debug file search path so no other binaries are found. Also fix a segfault if no binary is specified while here.

Alexander Kanavin	0d5475a3b2	package.bbclass: replace rpm/debugedit with dwarfsrcfiles ... Debugedit provided by rpm 4.14 is rewriting binaries in-place, and was found to produce broken output at least for grub: http://lists.openembedded.org/pipermail/openembedded-core/2017-November/143989.html A replacement utility was suggested via private mail: https://lists.fedorahosted.org/archives/list/elfutils-devel@lists.fedorahosted.org/message/VZP4G5N2ELYZEDAB3QYLXYHDGX4WMCUF/ (From OE-Core rev: f2e6e1d3bfd4c92ef0f5ed4721fd9050c59dafca) Signed-off-by: Alexander Kanavin <alexander.kanavin@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>	2018-01-02 17:24:36 +00:00
