2018-02-28httpboot: Amend the device path matching ruleGary Lin
Originally, we check if the last 2 nodes in the device path are IPv4()/Uri() or IPv6()/Uri() to determine whether httpboot is used or not. However, since UEFI 2.7, the DNS node will be inserted between the IP node and the URI node if the server provides the DNS server address. This commit changes the matching rule to search IP node and URI node and ignore any node between those two nodes. Signed-off-by: Gary Lin <glin@suse.com>

2017-09-29Make shim_cert.h able to be included more safely.Peter Jones
If you build with ENABLE_SHIM_CERT=1, the include chain right now winds up meaning shim_cert is defined in a header that gets included in netboot.c as well, which never uses it: In file included from shim.h:125:0, from netboot.c:36: shim_cert.h:1:14: error: ‘shim_cert’ defined but not used [-Werror=unused-variable] static UINT8 shim_cert[] = { ^~~~~~~~~ cc1: all warnings being treated as errors So make that okay by adding __attribute__((__unused__)) to the variable decl.

2017-09-26Use iconv for UCS-2 encoding.Peter Jones
Cyphermox discovered that when you run this: ( printf "\xff\x00\xfe\x00" ; echo "shimx64.efi,foo,,This is the boot entry for foo" ) | sed -z 's/./&\x00/g' on some debian machines, printf(1) doesn't interpret the \x.. characters, and that results in this being the encoded text: 00000000 5c 78 66 66 5c 78 66 65 73 00 68 00 69 00 6d 00 |\xff\xfes.h.i.m.| 00000010 78 00 36 00 34 00 2e 00 65 00 66 00 69 00 2c 00 |x.6.4...e.f.i.,.| 00000020 66 00 6f 00 6f 00 2c 00 2c 00 54 00 68 00 69 00 |f.o.o.,.,.T.h.i.| which... yeah, that's wrong. So instead, use iconv instead of printf+sed to encode it in UCS-2. Unfortunately, that means we don't get endian markers, because for some reason iconv(1) doesn't have any way to say it should include them. But that's okay; fallback already handles not having them and just assumes the second byte being \x00 means UCS-2LE. Signed-off-by: Peter Jones <pjones@redhat.com>

2017-08-31Cryptlib: Include stddef.h in CrtLibSupport.hGary Lin
The changes in the openssl headers cause the inclusion of CrtLibSupport.h eariler than the inclusion of stddef.h, so "offsetof" was defined twice and this caused the followling build error: In file included from Cryptlib/Include/openssl/buffer.h:23:0, from Cryptlib/Include/openssl/x509.h:22, from shim.c:56: /usr/lib64/gcc/x86_64-suse-linux/6/include/stddef.h:417:0: error: "offsetof" redefined [-Werror] #define offsetof(TYPE, MEMBER) __builtin_offsetof (TYPE, MEMBER) In file included from Cryptlib/Include/limits.h:15:0, from Cryptlib/Include/openssl/ossl_typ.h:13, from Cryptlib/Include/openssl/x509.h:20, from shim.c:56: Cryptlib/Include/CrtLibSupport.h:192:0: note: this is the location of the previous definition #define offsetof(type, member) ( (int) & ((type*)0) -> member ) We can lower the priority of the gcc include path or just remove the path, but this might cause problem since the path was introduced on purpose(*). Instead, including stddef.h first is more feasible. (*) https://github.com/rhinstaller/shim/commit/d51739a416400ad348d8a1c7e3886abce11fff1b Signed-off-by: Gary Lin <glin@suse.com>
2017-08-31Revert lots of Cryptlib updates.Peter Jones
OpenSSL changes quite a bit of the key validation, and most of the keys I can find in the wild aren't marked as trusted by the new checker. Intel noticed this too: https://github.com/vathpela/edk2/commit/f536d7c3ed but instead of fixing the compatibility error, they switched their test data to match the bug. So that's pretty broken. For now, I'm reverting OpenSSL 1.1.0e, because we need those certs in the wild to work. This reverts commit 513cbe2aea689bf968f171f894f3d4cdb43524d5.

2017-08-18Rework looping in enter_mok_menu(), to allow multiple MOK changesMathieu Trudel-Lapierre
Rather than looping once through the possible actions (MokNew, MokDel, etc.), revise the logic so that instead of rebooting immediately we get back to the main menu setting a flag to replace "Continue booting" with a proper reboot. Getting back to the menu means we can go make other changes before rebooting. For instance, you might want to enable validation, but beforehand you also need to enroll a MOK. You can already do so from userland; except the requests were cleared as soon as one of them was processed. This involves some extra cleanup of the states to avoid running the same request more than once, removing the option from the menu once it's done, and changing prompting functions to return an EFI_STATUS so we can better track whether the process has succeeded.

2017-08-11fallback: work around the issue of boot option creation with AMI BIOSLans Zhang
AMI BIOS (e.g, Intel NUC5i3MYHE) may automatically hide and patch BootXXXX variables with ami_masked_device_path_guid.

2017-08-11fallback: fix double free of dpLans Zhang
If the boot option recorded in csv is not in a media device path, the corresponding full device path will be referred for creating the boot variable. However, the current code logic always frees the full device path (full_device_path) and the media device path (dp) separately. In order to resolve this issue, always check whether dp equals to full_device_path before freeing dp. Signed-off-by: Lans Zhang <jia.zhang@windriver.com>
