6 : /* This file is responsible for serializing and deserializing
7 : the input region of the BPF virtual machine. The input region contains
8 : instruction information, account metadata, and account data. The high level
9 : format is as follows:
10 :
11 : [ account 1 metadata, account 1 data, account 2 metadata, account 2 data, ...,
12 : account N metadata, account N data, instruction info. ]
13 :
14 : This format by no means comprehensive, but it should give an idea of how
15 : the input region is laid out. When direct mapping is not enabled, the input
16 : region is stored as a single contiguous buffer. This buffer in the host
17 : address space is then mapped to the VM virtual address space (the range
18 : starting with 0x400...). This means to serialize into the input region, we
19 : need to copy in the account metadata and account data into the buffer for
20 : each account. Everything must get copied out after execution is complete.
21 : A consequence of this is that a memcpy for the account data is required
22 : for each serialize and deserialize operation: this can potentially become
23 : expensive if there are many accounts and many nested CPI calls. Also, the
24 : entire memory region is treated as writable even though many accounts are
25 : read-only. This means that for all read-only accounts, a memcmp must be done
26 : while deserializing to make sure that the account (meta)data has not changed.
27 :
28 : Direct mapping offers a solution to this by introducing a more sophisticated
29 : memory translation protocol. Now the account data is not copied into a single
30 : contiguous buffer, but instead a borrowed account's data is directly mapped
31 : into the VM's virtual address space. The host memory for the input region is
32 : now represented by a list of fragmented memory regions. These sub regions
33 : also have different write permissions. This should solve the problem of
34 : having to memcpy/memcmp account data regions (which can be up to 10MiB each).
35 : There is some nuance to this, as the account data can be resized. This means
36 : that memcpys for account data regions can't totally be avoided.

38 : SERIALIZATION BEHAVIOR
39 : ==========================================
40 :
41 : This implementation supports three distinct serialization modes based on two
42 : feature flags: virtual_address_space_adjustments and
43 : account_data_direct_mapping.
44 :
45 : MODE 1
46 : --------------------------------------
47 : virtual_address_space_adjustments = false
48 : account_data_direct_mapping = false
49 :
50 : Memory Layout:
51 : - Single contiguous buffer in host memory
52 : - Buffer contains: [metadata1, data1, realloc_buffer1, metadata2, data2,
53 : realloc_buffer2, ..., metadataN, dataN, realloc_bufferN, instruction_info]
54 : - Each account gets: original data + MAX_PERMITTED_DATA_INCREASE (10KiB)
55 : - Padding added to maintain 16-byte alignment between accounts
56 : - Entire buffer is writable
57 :
58 : Memory Regions:
59 : - The entire input region buffer is mapped as one contiguous VM address
60 : space region
61 :
62 : Serialization Process:
63 : - Account data is memcpy'd into the buffer
64 : - 10KiB realloc buffer is zeroed out and appended after each account's data
65 : - Alignment padding is zeroed and added after realloc buffer
66 :
67 : Deserialization Process:
68 : - Account data must be memcpy'd back from buffer to borrowed account
69 : - For writable accounts: always copy data back
70 : - For read-only accounts: memcmp to verify data unchanged, error if modified
71 : - Account resizing allowed if account permissions permit it
72 :
73 : MODE 2
74 : -------------------------------------------
75 : virtual_address_space_adjustments = true
76 : account_data_direct_mapping = false
77 :
78 : Memory Layout:
79 : - Still uses a single contiguous buffer, but organized into fragmented
80 : regions.
81 : - Each account now has separate regions for metadata and data+realloc.
82 : - Buffer contains: [metadata1, data1+realloc1, metadata2, data2+realloc2, ...,
83 : metadataN, dataN+reallocN, instruction_info].
84 : - Each metadata region and data region tracked separately in
85 : input_mem_regions.
86 :
87 : Memory Regions:
88 : - For each account:
89 : * Region 0: Account metadata (writable)
90 : * Region 1: Account data + realloc space (writable if account is writable)
91 : - If the account is owned by the deprecated loader, no realloc region is
92 : created as the deprecated loader does not support resizing accounts.
93 :
94 : Serialization:
95 : - Account metadata serialized first, added as a memory region.
96 : - Account data memcpy'd into buffer - not directly mapped.
97 : - 10KiB realloc buffer zeroed and appended (not direct mapped).
98 : - Data region created pointing to copied data in buffer.
99 :
100 : MODE 3: Direct Mapping (requires virtual_address_space_adjustments)
101 : -----------------------------------------------
102 : virtual_address_space_adjustments = true
103 : account_data_direct_mapping = true
104 :
105 : This is very similar to virtual_address_space_adjustments, but account
106 : data is NOT copied into the input region buffer.
107 :
108 : Instead, the data region points directly to the staging area for the
109 : account in the transaction account's data. This staging area has enough
110 : space to hold the account data and the realloc buffer. Changes to this
111 : staging area will be written back to the account database in transaction
112 : finalization.
