2021-03-23Remove all out outstanding patchesSteve McIntyre
* cast-CHAR8-string-handling.patch no longer needed * fix-Make.coverity-bashisms.patch went upstream
2021-03-23Update copyright fileSteve McIntyre
Update a couple of top-level changes, copy in gnu-efi information from the gnu-efi package
2021-03-23Fix up some of the options we're using at build timeSteve McIntyre
Definitely don't want to be setting EFI_PATH, as that over-rides the vendored gnu-efi. Argh
2021-03-23Improve how the dbx hashes are handledSteve McIntyre
Only include the hashes for the architecture we're building for - no point in adding bloat and delay here. Add a script "block_signed_deb" to scan a set of .deb files, extract the hashes for .efi binaries and list them in the format wanted for the dbx hashes file. Split out the code to use that file from the rules file into a separate helper.

2021-02-20Include missing .text sections in PE/COFF binaryChris Coulson
At the default -Os optimization level, gcc emits ".text.startup" and ".text.unlikely" sections for static initializers and noreturn functions which end up in the intermediate ELF binary: $ objdump -h build-x64/shimx64.efi.so build-x64/shimx64.efi.so: file format elf64-x86-64 Sections: Idx Name Size VMA LMA File off Algn 0 .text 00046e7b 0000000000001000 0000000000001000 00001000 2**10 CONTENTS, ALLOC, LOAD, READONLY, CODE 1 .text.startup 00000118 0000000000047e7b 0000000000047e7b 00047e7b 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 2 .text.unlikely 00000046 0000000000047f93 0000000000047f93 00047f93 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 3 .data 000315e8 0000000000048000 0000000000048000 00048000 2**9 These additional .text.* sections are omitted from the final PE/COFF binary, resulting in a crash when processing the ctors.

[edited by pjones to use .text.* instead of naming the sections individually, and to sync up with what other arches have in .text]

2021-02-19sbat: Fix two NULL derefs found with "gcc -fanalyzer"Peter Jones
"gcc -fanalyzer" found two NULL pointer checks we're missing in sbat.c: include/str.h: In function ‘get_sbat_field.part.0’: sbat.c:20:14: error: dereference of NULL ‘offset’ [CWE-476] [-Werror=analyzer-null-dereference] 20 | if (!*offset) and include/str.h: In function ‘parse_sbat’: sbat.c:140:27: error: dereference of NULL ‘current’ [CWE-476] [-Werror=analyzer-null-dereference] 140 | } while (entry && *current != '\0'); Both are simple, and this patch fixes them.

2021-02-19sbat: make shim to parse it's own .sbat section on initJavier Martinez Canillas
This is needed for shim to verify itself when booting, to make sure that shim binaries can't be executed anymore after been revoked by SBAT. Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>
2021-02-19shim: initialize OpenSSL after parsing SBAT dataJavier Martinez Canillas
A following patch will make shim to verify its .sbat section and it should be done before doing the OpenSSL initialization. But having the debugger attached may be useful at this point. Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>
2021-02-19sbat: include NULL terminator when calculating buffer end in parse_sbat()Javier Martinez Canillas
The parse_sbat() function is currently removing the last character of the passed buffer, which will usually be a null-terminated string to parse. There's no reason to do this and just take the whole size as specified by the caller. Reported-by: Chris Coulson <chris.coulson@canonical.com> Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>
2021-02-19pe.c: move sbat verification to its own function.Peter Jones
handle_image() is quite huge and complex. This patch moves the SBAT validation code from handle_image() to a new function, handle_sbat(). Signed-off-by: Peter Jones <pjones@redhat.com>
2021-02-19Don't re-parse the SBAT EFI variable for each binary we load.Javier Martinez Canillas
On a typical boot we validate at least two binaries; parsing the SBAT EFI variable each time, when it should not be changing, is not worth the effort. This patch moves the parsing out to some setup code, instead of doing it during the verification stage. Signed-off-by: Peter Jones <pjones@redhat.com>

2021-02-19pe.c: parse SBAT variable and perform basic verificationAlex Burmashev
Per Peter Jones suggestion, we will be flexible in what data we expect while parsing the variable. Three fields are mandatory: component_generation, component_name_size, component_name However we also support adding comments and additional information to be added after component name, with ',' as a separator. Those information will be ignored and not used for verification purposes. So: grub,1 and grub,1,wow,this,is,my,comment will provide exactly same set of data for verification.

2021-02-19sbat: drop the struct sbat and just use two variables insteadPeter Jones
The struct sbat isn't doing anything and only has two fields so let's pass pass those two to the functions directly instead of storing it in a struct. Signed-off-by: Peter Jones <pjones@redhat.com>
