Takes a [[NCM_services#StorageId|StorageId]], an u64 ProcessId, a [[NCM_services#ProgramId|ProgramId]], a 0x1C type-A buffer for the [[NPDM#FS_Access_Header| FS Access Header]], and a 0x2C type-A buffer for the [[NPDM#FS_Access_Control| FS Access Control]]
    
Final FS permissions are stored as (ACI0_perms & ACID_perms). Will panic(svcBreak) when buffer sizes from ipc-rawdata are invalid.

When the flag is zero, it will set ret=0 instead of ret={error} when verifying the fixed-key [[NPDM]] ACID signature fails. This also skips verifying the [[NCA_Format|NCA Header]] signature using the ACID key. Note that if verifying the fixed-key ACID signature is successful, and verifying the ACID-key NCA header signature fails, it will throw an error and abort.

These variables don't seem to be actually used anywhere else (?)
+
== OpenFileSystem ==
 +
Takes a type-0x19 input [[#ContentPath]] and a [[#FileSystemProxyType]] as parameters. Returns an [[#IFileSystem]].
   −
== SetSaveDataRootPath ==
+
[2.0.0+] This function was removed.
−
Takes an input path, and does snprintf(<fsp-srv object>->m_save_data_root_path, FS_MAX_PATH-1, "/%s", input_path);
     −
This path is normally all-zero. When this path is non-zero, the internal OpenSaveDataFileSystem function will create a DirectorySaveDataFileSystem if the target save is a user-save + a directory exists, instead of the normal savedata filesystem object.
+
== SetCurrentProcess ==
 +
Takes a pid-descriptor.
   −
== SetGlobalAccessLogMode ==
+
== OpenFileSystemWithPatch ==
−
Takes an input u32.
+
Takes an input [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].
   −
== SetGlobalAccessLogMode ==
+
Web-applet loads the [[#FileSystemProxyType]] (which must be '''Manual''') from u32_table[inparam].
−
Takes an input u32.
     −
== GetGlobalAccessLogMode ==
+
Note: web-applet strings refer to both this cmd and [[#OpenFileSystemWithId]] as "MountContent", but official nn_sf_sync symbols use "OpenXX" names.
−
Returns an output u32.
+
 
 +
== OpenFileSystemWithId ==
 +
Takes a type-0x19 input buffer, an [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].
   −
GlobalAccessLogMode is normally 0.
+
The [[#IFileSystem]] must be '''Meta''' if the NCA type is 0.
   −
== OutputAccessLogToSdCard ==
+
The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].
−
Takes a type-0x5 input buffer.
     −
The input buffer is the string to output to the log. User-processes normally include a newline at the end.
+
May return errors when attempting to access NCA-paths for an update-title with a gamecard, when the gamecard isn't inserted. May return error 0x7D402 in some cases with update-titles. Non-val2 in32 values with NCA-type1 are unusable, even for normal titles.
   −
User-processes only use this when the value previously loaded from [[#GetGlobalAccessLogMode]] has bit1 set.
+
The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemProxyType]] '''Package'''.
   −
When bit1 in GlobalAccessLogMode is clear, FS-module will just return 0 for OutputAccessLogToSdCard. However even with that set the log doesn't show up SD, unknown why.
+
After the [[#FileSystemProxyType]] specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.
   −
The input buffer is written to the "$FsAccessLog:/FsAccessLog.txt" file, where "$FsAccessLog" is the SD-card mount-name. It's written to the current end of the file(appended).
+
When [[#FileSystemProxyType]] is '''Meta''', it uses in64=0xffffffffffffffff internally, otherwise it checks if in64 is set to 0xffffffffffffffff then throws an error if so. When the in64 used internally is not 0xffffffffffffffff, it's compared with the NCA [[NCM_services#ProgramId|ProgramId]], then an error is thrown on mismatch.
   −
== GetProgramIndexForAccessLog ==
+
== OpenBisFileSystem ==
−
No input, returns two 32-bit values "version" and "program_index".
+
Takes a type-0x19 input buffer string and a [[#BisPartitionId]]. Official user-process code sets instr[0] = 0 normally. Returns an [[#IFileSystem]].
   −
== OpenMultiCommitManager ==
+
Only partitionIDs for FAT partitions are usable with this, otherwise error 0x2EE202 is returned. Seems to be about the same as [[#OpenBisStorage]] except this mounts the partition filesystem instead of allowing direct access to the partition sectors.
−
No input, returns an output [[#IMultiCommitManager]].
     −
= IStorage =
+
== OpenBisStorage ==
−
This is "nn::fssrv::sf::IStorage".
+
Takes a u32 partition ID, returns 0x2EE202 for partitions which do not exist, 0x320002 for partitions which cannot be opened and a valid [[#IStorage]] handle otherwise.
   −
This is the interface for a raw device, usually a block device.
+
== InvalidateBisCache ==
 +
Seems to invalidate the Bis cache for MBR/GPT after overwriting that data via the OpenBisStorage IStorage. Used by [[SystemInitializer]].

== OpenGameCardFileSystem ==
 +
Takes two input u32s, with the second u32 located at +4 in rawdata after the first u32. Returns an [[#IFileSystem]].

Mounts a [[Gamecard_Partition|gamecard partition]].
 +
 
 +
== CreateSaveDataFileSystemWithHashSalt ==
 +
Takes a total of 0xB0-bytes of input, no output.
 +
 
 +
== OpenSaveDataFileSystem ==
 +
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte [[#SaveDataAttribute]]. Official user-process code is only known to use value 1 for the u8.
 +
 
 +
Returns an [[#IFileSystem]].
 +
 
 +
Permissions aren't checked until the specified save is successfully found.
   −
* '''RomFS''': Filesystem implementation statically linked in the binary. Uses an [[#IStorage]] interface as underlying raw device.
+
Only one process (specifically only one [[#IFileSystem]] session) can mount a given savedata at any given time (this includes SystemSaveData).
−
* '''IPC proxy''': Used for all non-RomFS filesystems. In this case, actual filesystem implementation is in the FS process.

−
* Output u64 with ARMS-gamecard: titleID 0100000000000816.
+
Returns an output u32.
   −
[[NS_Services|NS]] appears to only use this with [[Content_Manager_services#GetTitleIdInfo]] and [[Content_Manager_services#GetUpdateTitleList]] with storageid=nandsys, for checking whether a sysupdate is required.
+
GlobalAccessLogMode is normally 0.
   −
== GetGameCardDeviceCertificate ==
+
== OutputAccessLogToSdCard ==
−

     −
[9.0.0+] The [[Account_services|account]] system module uses this as part of a new challenge-response mechanism for [[Network#aauth|application authentication]].
+
User-processes only use this when the value previously loaded from [[#GetGlobalAccessLogMode]] has bit1 set.
   −
== GetGameCardCompatibilityType ==
+
When bit1 in GlobalAccessLogMode is clear, FS-module will just return 0 for OutputAccessLogToSdCard. However even with that set the log doesn't show up SD, unknown why.
−

There are two main implementations of this interface:
   −

* '''nn::fs::fsa::IFileSystem''': The main IFileSystem implementation. Filesystem classes implement this interface, and FS code usually operates on this interface.
−
Takes an input u8 [[#SaveDataSpaceId]] and u64, returns an [[#ISaveDataExporter]].
+
* '''nn::fssrv::sf::IFileSystem''': Used for sending an IFileSystem over IPC. Not used outside of IPC code.
   −
== OpenSaveDataImporter ==
+
There are two adapter classes to convert between these interfaces:
−
Takes an input u8 [[#SaveDataSpaceId]] and a 0x10-byte userID, and a type-0x5 input buffer. Returns an output u64 and an [[#ISaveDataImporter]].
     −
= ISaveDataTransferManagerForSaveDataRepair =
+
* '''nn::fssrv::detail::FileSystemInterfaceAdapter''': Allows access to an nn::fs::fsa::IFileSystem via the nn::fssrv::sf::IFileSystem interface.
−
This is "nn::fssrv::sf::ISaveDataTransferManagerForSaveDataRepair".
+
* '''nn::fs::detail::FileSystemServiceObjectAdapter''': Allows access to an nn::fssrv::sf::IFileSystem via the nn::fs::fsa::IFileSystem interface.
   −
This was added with [[9.0.0]].
+
When the FS process returns a filesystem, it will wrap the filesystem object in a FileSystemInterfaceAdapter to return it over IPC.
 +
Then when FS application code receives that filesystem, it will wrap the nn::fssrv::sf::IFileSystem object in a FileSystemServiceObjectAdapter before using it.
