Paulo Flabiano Smorigo 872dec5684 Add powerpc little-endian (ppc64le) flags
libgcc dependency was removed *just* for this target because
the distros that use ppc64el doesn't have 32-bit support on it.

* configure.ac: Add targets for powerpc64el and skip libgcc.
* Makefile.am: Likewise.

David Kozub 17328db3b3 grub-core/kern/arm/misc.S: fix unaligned grub_uint64_t local variable
The unaligned local in __aeabi_uidivmod leads to a store to a 64bit
value at an address that is not divisible by 8 (in grub_divmod64).
The compiler most likely generates a STRD instruction to store it and
this causes an exception.

Fixes Savannah bug #43632.

This includes improvements done by Leif Lindholm.

Andrei Borzenkov cdae5bf208 Avoid use of non-portable echo -n in grub-mkconfig
util/grub-mkconfig_lib.in(version_test_gt): "echo -n" is not really needed,
final newline is stripped by command substitution.

util/grub.d/10_kfreebsd.in, util/grub.d/10_linux.in,
util/grub.d/20_linux_xen.in: change how list is built, to avoid echo -n
completely.

util/grub.d/30_os-prober.in: add spaces to printed line directly

Closes 43668.

Curtis Larsen 06eadf5ebf fix double free in grub_net_recv_tcp_packet
Using the http module to download config files, produces memory errors,
after the config file is downloaded.

The error was traced to the tcp stack in grub-core/net/tcp.c. The wrong
netbuff pointer was being freed in the clean up loop.

Changing the code to free the correct netbuff pointer removes the runtime
error.

Closes 42765.

Andrei Borzenkov ebb3d958aa fix memory corruption in pubkey filter over network
grub_pubkey_open closed original file after it was read; it set
io->device to NULL to prevent grub_file_close from trying to close device.
But network device itself is stacked (net -> bufio); and bufio preserved
original netfs file which hold reference to device. grub_file_close(io)
called grub_bufio_close which called grub_file_close for original file.
grub_file_close(netfs-file) now also called grub_device_close which
freed file->device->net. So file structure returned by grub_pubkey_open
now had device->net pointed to freed memory. When later file was closed,
it was attempted to be freed again.

Change grub_pubkey_open to behave like other filters - preserve original
parent file and pass grub_file_close down to parent. In this way only the
original file will close device. We really need to move this logic into
core instead.

Also plug memory leaks in error paths on the way.

Andrei Borzenkov 272e0466da add file filters tests
Tests file access with all filters enabled. It does it both for local
and network access, due to regression in signature checking over network.

This includes all files in distribution to not depend on existence
of compression tools and gpg. Test preloads all required modules to
avoid having to provide signatures for them.

Still not implemented is file offset filter (is not available in grub
script, needs extra module)
