Zach Hilman 0aef2b9c26 crypto: Use compressed sizes in offset calculation for KIP decompression 
Fixes a fatal crash on start when deriving keys.

Lioncash 6467b01de2 partition_data_manager: Reserve and insert data within output vector in DecryptPackage2() 
We can just reserve the memory then perform successive insertions
instead of needing to use memcpy. This also avoids the need to zero out
the output vector's memory before performing the insertions.

We can also std::move the output std::vector into the destination so
that we don't need to make a completely new copy of the vector, getting
rid of an unnecessary allocation.

Additionally, we can use iterators to determine the beginning and end
ranges of the std::vector instances that comprise the output vector, as
the end of one range just becomes the beginning for the next successive
range, and since std::vector's iterator constructor copies data within
the range [begin, end), this is more straightforward and gets rid of the
need to have an offset variable that keeps getting incremented to
determine where to do the next std::memcpy.

Lioncash 781fd7983c partition_data_manager: Remove unused std::map instance within DecryptPackage2() 
Aside from emplacing elements into the map, the map itself is never
actually queried for contained data.

Lioncash e0c76226ad partition_data_manager: Take package2_keys by const reference 
These are only ever read from, so we don't need to make a copy of all
the keys here.
 2018-10-13 09:24:41 -04:00
Lioncash 3d9df49619 partition_data_manager: Move IV data to where it's needed in DecryptPackage2() 
Given it's only used in one spot and has a fairly generic name, we can
just specify it directly in the function call. This also the benefit of
automatically moving it.
 2018-10-13 09:20:21 -04:00
Lioncash bc2196bb09 partition_data_manager: Remove commented out code 
Commented out code shouldn't be left in without a reason indicating why
in a comment.

Lioncash 6da2ed4232 key_manager/partition_data_manager: Silence truncation compiler warnings 2018-10-13 09:13:19 -04:00
Lioncash f56a8da46a partition_data_manager: Dehardcode array bounds 
Instead, we can make it part of the type and make named variables for
them, so they only require one definition (and if they ever change for
whatever reason, they only need to be changed in one spot).
 2018-10-13 08:52:37 -04:00
Lioncash d257a3b56c partition_data_manager: Take VirtualFile by const reference in constructor 
Given the VirtualFile instance isn't stored into the class as a data
member, or written to, this can just be turned into a const reference,
as the constructor doesn't need to make a copy of it.
 2018-10-13 08:39:05 -04:00
Lioncash e96d69c328 partition_data_manager: Amend constructor initializer list order 
Orders the members in the exact order they would be initialized. This
also prevents compiler warnings about this sort of thing.

Lioncash aaca7543f0 partition_data_manager: Remove unused includes 
Gets unused includes out of the headers and moves them into the cpp file
if they're used there instead.
 2018-10-13 08:33:49 -04:00
Lioncash 06898263f6 key_manager: Use std::vector's insert() instead of std::copy with a back_inserter 
If the data is unconditionally being appended to the back of a
std::vector, we can just directly insert it there without the need to
insert all of the elements one-by-one with a std::back_inserter.
 2018-10-13 08:29:35 -04:00
Lioncash e70c08b543 key_manager: Brace long conditional body 
If a conditional (or it's body) travels more than one line, it should be
braced.
 2018-10-13 08:24:21 -04:00
Lioncash ef5639bfbb key_manager: Don't assume file seeks and reads will always succeed 
Given the filesystem should always be assumed to be volatile, we should
check and bail out if a seek operation isn't successful. This'll prevent
potentially writing/returning garbage data from the function in rare
cases.

This also allows removing a check to see if an offset is within the
bounds of a file before perfoming a seek operation. If a seek is
attempted beyond the end of a file, it will fail, so this essentially
combines two checks into one in one place.

Lioncash 82ea1cf35a key_manager: Remove unnecessary seek in DeriveSDSeed() 
Given the file is opened a few lines above and no operations are done,
other than check if the file is in a valid state, the read/write pointer
will always be at the beginning of the file.

Lioncash c1f76abfaf key_manager: Use regular std::string instead of std::string_view 
The benefit of std::string_view comes from the idea of avoiding copies
(essentially acting as a non-owning view), however if we're just going
to copy into a local variable immediately, there's not much benefit
gained here.
