build-id, branch masterExample code for reading an ELF binary's .note.gnu.build-id section, from the program itselfhttp://git.mattst88.com/build-id/atom/?&h=master2022-04-03T23:23:16ZHandle case of NULL dlpi_name2022-04-03T23:23:16ZMatt Turnermattst88@gmail.com2022-04-03T23:23:16Zurn:sha1:3453c3fc3516996fc9a96469249ee7a223e5e32b
Apparently this can happen on some versions of Android. Fixed in Mesa
with commit 70d25cae8b9 ("util/build-id: check dlpi_name before strstr
call").
Closes: https://github.com/mattst88/build-id/issues/5
Remove usage of bash '&>' redirection2020-06-24T17:32:21ZNeil Rozaneil@rtr.ai2020-06-23T13:35:18Zurn:sha1:72ea519e3563df60fe81a9534e0b8b85bd63a37f
On systems where /bin/sh is dash, this would lead to empty *.expected
and *.results files and thus make check would always succeed.
Closes: #1

The dladdr(3) explains that dladdr often doesn't do what you expect
because the function pointer will point to the PLT entry in the original
object and not the actual function itself.
Test that by_symbol returns the same nhdr as by_name2019-04-25T17:52:20ZMatt Turnermattst88@gmail.com2019-04-25T17:38:53Zurn:sha1:5380624471e4ac22edd397cd91289844650ef5e5Fix address comparison for binaries with LOAD vaddr > 02019-04-25T17:52:20ZMatt Turnermattst88@gmail.com2019-04-25T17:37:18Zurn:sha1:df84371bae98aa0724aa7926822da44cbcd3fbca
