* insane: Recognise BPF as a valid EM_MACHINE typeKhem Raj2018-09-131-1/+2
| | | | | | | | | | | | | | | | BPF Linux ELF objects are generated with kernel-selftests with >= 4.18 kernel and when clang is enabled which packages BPF objects into packages, therefore recongnise this as a valid ELF target Add a selftest for BPF Do not flag BPF objects in target, since they pretty much will be ok for most of kernels architectures we care do support BPF (From OE-Core rev: 3667a8ec016bae3f8026ef7b4c895546804f6368) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* meta: remove True option to getVar callsJoshua Lock2016-12-161-2/+2
| | | | | | | | | | | | | getVar() now defaults to expanding by default, thus remove the True option from getVar() calls with a regex search and replace. Search made with the following regex: getVar ?\(( ?[^,()]*), True\) (From OE-Core rev: 7c552996597faaee2fbee185b250c0ee30ea3b5f) Signed-off-by: Joshua Lock <joshua.g.lock@intel.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* lib/oe/qa: handle binaries with segments outside the first 4kbRoss Burton2016-11-151-41/+41
| | | | | | | | | | | | | | The ELF parser was assuming that the segment tables are in the first 4kb of the binary. Whilst this generally appears to be the case, there have been instances where the segment table is elsewhere (offset 2MB, in this sample I have). Solve this problem by mmap()ing the file instead. Also clean up the code a little whilst chasing the problem.

* lib/oe/qa: add ELF machine to string functionRoss Burton2016-10-111-0/+20
| | | | | | | | | | Add a function (and test suite) to turn the ELF machine field (e_machine) into a string, so we can tell the user "x86-64" instead of 0x3E.

| | | | | | | | | | | | | Instead of raising a generic Exception that can't be handled specifically, raise a ValueError. Also update the callers so any unexpected exceptions are not ignored.

| | | | | | | | | | | | | When opening an ELF file check that a filename points to a normal file before attempting to open it, as if the file turns out to be something more exotic like a FIFO it could hang forever.

* qa.py: Toolchain path should not be hardcoded to execute objdumpMuhammad Shakeel2012-12-061-2/+2
| | | | | | | | | | | | | | Currently objdump command is invoked from the STAGING_BINDIR_TOOLCHAIN directory. In case of external toolchain if this directory doesn't exist then objdump fails to execute. Instead of hardcoding the path it should search PATH to find it.

* insane: Rationalise phdrs-based QA checksPhil Blundell2012-10-181-0/+17
| | | | | | | | | | | | | | | | | | Various different QA checks are based on essentially the same data from the ELF program headers. Calling objdump to extract it repeatedly is inefficient, particularly if the shell is involved. Instead, let's cache the output from objdump inside the qa.elf object and allow it to be reused by multiple tests. Also, using objdump instead of scanelf to check for bad RPATHs (in the same way that the useless-rpaths check was doing already) allows the dependency on pax-utils-native to be dropped.

* insane.bbclass: Fix ELF bitsize comparisonMark Hatle2011-03-031-4/+17
| | | | | | | | | | | | | | | | Fix the way the ELF size is compared to ensure that incorrectly sized ELF binaries are captured during the file scan. lib/oe/qa.py is changed to accept a bitsize as a parameter. Instead of previously defining true/false, it now takes "0" undefined, "32" 32-bit, and "64" 64-bit as the size argument. This allows us to preserve existing behavior of only loading one ELF type, while allowing the function to be able to discover the size on it's own.
