-Barrelfish offers a simple \acs{vfs} layer for accessing different filesystems.\r
-blockdevfs adds a further layer to facilitate exporting of file-like objects to\r
-the filesystem layer. There is no restriction on the nature of these files,\r
-apart from having to be of a fixed size.\r
-\r
-The backends of blockdevfs can expose an arbitrary number of filenames. The\r
-filenames from different backends are combined to form the root directory of\r
-the blockdevfs filesystem. \acs{vfs} calls are mapped to the corresponding backend.\r
-The filesystem only consists of a single directory with no nested directories.\r
-Files cannot be created nor deleted or truncated.\r
-\r
-\section{Datastructures}\r
-\r
-blockdevfs keeps a very simple doubly-linked list of directory entries. These\r
-entries contain a file name, file position, file size, backend type and backend\r
-handle. blockdevfs does not enforce any kind of order in this list. Therefore,\r
-enumerating the contents of the blockdevfs root directory will yield the files\r
-registered by blockdevfs backends in the order they were added to blockdevfs.\r
-When routing \acs{vfs} calls to the right backend, the number stored in backend type\r
-is used as an index into the \lstinline+backends+ array holding function\r
-pointers to the backend's operations.\r
-\r
-Figure \ref{fig:blockdevfs_list} shows how the directory structure looks like\r
-with two entries. \lstinline+prev+ and \lstinline+next+ are used to implement\r
-the linked list. \lstinline+path+ holds a pointer to the filename.\r
-\lstinline+size+ contains the size of the file in bytes. \lstinline+type+ is\r
-either $0$ for the \emph{libahci} backend or $1$ for the Flounder-based\r
-backend. \lstinline+backend_handle+ points to an internal handle private to the\r
-backend. \lstinline+open+ is a boolean value indicating if the file has been\r
-opened already.\r
-\r
-blockdevfs backends must use the \lstinline+blockdev_append_entry+ function to\r
-register files they export.\r

-\label{fig:blockdevfs_list}\r
-\end{figure}\r
-\r
-\section{Backend API}\r
-\r
-blockdevfs only exports \lstinline+blockdev_append_entry+ which can be used by\r
-backends to register their exported files. A backend can choose the\r
-\lstinline+backend_handle+ freely. This handle will be passed as an argument to\r
-all \acs{vfs} related functions.\r
-\r
-For standard \acs{vfs} operations, backends need to provide these four functions:\r
-\r
-\begin{itemize}\r
- \item \lstinline+open(void *handle)+ to open an exported file. The backend does not have to check or manipulate any blockdevfs-specific structures. blockdevfs ensures that only one client has a file open concurrently.\r
- \item \lstinline+close(void *handle)+ to close a previously opened file. As with open, blockdevfs takes care of manipulating its structures.\r
- \item \lstinline+read(void *handle, size_t pos, void *buffer, size_t bytes,+\\\r
- \lstinline+ size_t *bytes_read)+ to read from the file corresponding to the handle.\r
- \item \lstinline+write(void *handle, size_t pos, void *buffer, size_t bytes,+\\\r
- \lstinline+ size_t *bytes_written)+ to write to the file corresponding to the handle.\r
- \item \lstinline+flush(void *handle)+ to flush all data of the file\r
- correpsonding to the handle to persistent storage.\r
-\end{itemize}\r
-\r
-All functions are supplied with the backend-handle associated with the\r
-corresponding file.\r
-\r
-\section{Usage}\r
-\r
-blockdevfs can by mounted by issuing \verb+mount mountpoint blockdevfs://+ and\r
-does not accept any further parameters.\r
-\r
-Upon mounting, blockdevfs initializes its backends which in turn populate the\r
-list of directory entries. Listing the directory contents will yield any\r
-attached disk drives and report their sizes.\r
-\r
-\section{Backends}\r
-\r
-Currently the block device file system has two backends. One backend uses\r
-libahci stand-alone and the other backend uses the Flounder-generated \ac{ata}\r
-interface. The backends are named the \emph{ahci} and \emph{ata} backend\r
-respectively.\r
-\r
-As both these backends expose the same devices (namely any \ac{sata} disks\r
-attached to the \ac{ahci} controller), the file names for the devices are\r
-composed of the backend name and the device's unique id, e.g. \emph{ahci0} and\r
-\emph{ata0} for the device with unique id $0$. Keep in mind that \emph{ahcid}\r
-prevents concurrent access, therefore you can't open the respective \emph{ata}\r
-and \emph{ahci} devices at the same time.\r
-\r
-\subsection{AHCI Backend}\r
-\r
-The \ac{ahci} blockdevfs backend implements the open and close commands by\r
-calling the corresponding functions in libahci (\ahciinit and\r
-\lstinline+ahci_close+) and implements read and write by allocating a \acs{dma}\r
-buffer using \lstinline+ahci_dma_region_alloc+, constructing an appropriate\r
-\ac{fis} and calling \issuecmd. The read implementation updates the\r
-\lstinline+rx_vtbl.command_completed+ pointer to point to\r
-\lstinline+rx_read_command_completed_cb+. That function then uses\r
-\lstinline+ahci_dma_region_copy_out+ to copy the read bytes from the \acs{dma}\r
-buffer to the user buffer, frees the \acs{dma} buffer, and calls the user\r
-continuation. The write implementation copies the bytes that need to be written\r
-to the \acs{dma} buffer (using \lstinline+ahci_dma_region_copy_in+) and updates\r
-the \lstinline+rx_vtbl.command_completed+ pointer to point to\r
-\lstinline+rx_write_command_completed_cb+ which frees the \acs{dma} buffer and\r
-calls the user continuation. Flush is implemented by issuing the {\tt FLUSH\r
-CACHE} \ac{ata} command which flushes the on-disk cache to the harddisk proper.\r
-\r
-\subsection{ATA Backend}\r
-\r
-The \ac{ata} blockdevfs backend implements the open command by initializing an\r
-\acs{rpc} client to the \lstinline+ata_rw28+ Flounder \acs{ahci} interface. The\r
-close command just calls \verb+ahci_+ \verb+close+ so that a subsequent open-call\r
-on the same blockdevfs file is successful. The read, write and flush commands\r
-are easy to implement using the \acs{rpc} client to the Flounder \acs{ahci}\r
-interface by just calling the \lstinline+read_dma+, \lstinline+write_dma+ and\r
-\lstinline+flush_cache+ functions in the \acs{rpc} function table.\r
-\r
-\section{Restrictions}\r
-\r
-As blockdevfs is only intended to provide a simple way for \acs{vfs} aware\r
-applications (e.g. fish) it has several restrictions:\r
-\r
-\begin{itemize}\r
- \item The size of the files should not change. Although a backend might change\r
- the size stored in the handle dynamically, blockdevfs is not geared\r
- towards this.\r
- \item Subdirectories are not supported.\r
- \item Only one client can have a file open.\r
- \item Files cannot be removed, neither by the user nor by the backend.\r
-\end{itemize}\r
-\r
-\section{VFS adaptation}\r
-\r
-In order to ensure that data written to a block device really gets written to\r
-the hard disk, we added a new \acs{vfs} call, namely \lstinline+vfs_flush+,\r
-which is used to flush the hard disk's volatile cache. \lstinline+vfs_flush+\r
-returns \lstinline+VFS_ERR_NOT_IMPLEMENTED+ for \acs{vfs} backends that have no\r
-handler for flush in their \lstinline+struct vfs_ops+ table.\r
-\r

-\r
- ++ New features:\r
-\r
- 2016-07-27: Simon Goldschmidt\r
- * opt.h, timeouts.h/.c: added LWIP_TIMERS_CUSTOM to override the default\r

- passive open to inform the application about this error\r
- ATTENTION: applications have to handle NULL pcb in accept callback!\r
-\r

- * Initial 6LoWPAN support\r
-\r
- 2016-02-XX to 2016-03-XX: Dirk Ziegelmeier\r
- * Cleanup TCPIP thread sync methods in a way that it is possibe to use them\r
- in arbitrary code that needs things to be done in TCPIP thread. Used to\r
- decouple netconn, netif, ppp and 6LoWPAN from LWIP core.\r
-\r
- 2016-02-XX: Dirk Ziegelmeier\r
- * Implement dual-stack support in RAW, UDP and TCP. Add new IP address\r
- type IPADDR_ANY_TYPE for this. Netconn/Socket API: Dual-stack is\r
- automatically supported when an IPv6 netconn/socket is created.\r
-\r
- 2015-12-26: Martin Hentschel and Dirk Ziegelmeier\r
- * Rewrite SNMP agent. SNMPv2c + MIB compiler.\r
-\r
- 2015-11-12: Dirk Ziegelmeier\r

- Breaking change: Users have to call snmp_init() now!\r
-\r
- 2015-11-12: Dirk Ziegelmeier\r
- * Implement possibility to declare private memory pools. This is useful to\r
- decouple some apps from the core (SNMP stack) or make contrib app usage\r
- simpler (httpserver_raw)\r
-\r
- 2015-10-09: Simon Goldschmidt\r
- * started to move "private" header files containing implementation details to\r
- "lwip/priv/" include directory to seperate the API from the implementation.\r
-\r
- 2015-10-07: Simon Goldschmidt\r
- * added sntp client as first "supported" application layer protocol implementation\r
- added 'apps' folder\r
-\r
- 2015-09-30: Dirk Ziegelmeier\r
- * snmp_structs.h, mib_structs.c, mib2.c: snmp: fixed ugly inheritance\r
- implementation by aggregating the "base class" (struct mib_node) in all\r
- derived node classes to get more type-safe code\r
-\r
- 2015-09-23: Simon Goldschmidt\r
- * netif.h/.c, nd6.c: task #13729: Convert netif addresses (IPv4 & IPv6) to\r
- ip_addr_t (so they can be used without conversion/temporary storage)\r
-\r
- 2015-09-08: Dirk Ziegelmeier\r
- * snmp: Separate mib2 counter/table callbacks from snmp agent. This both cleans\r
- up the code and should allow integration of a 3rd party agent/mib2. Simple\r
- counters are kept in MIB2_STATS, tree/table change function prototypes moved to\r
- snmp_mib2.h.\r
-\r
- 2015-09-03: Simon Goldschmidt\r
- * opt.h, dns.h/.c: DNS/IPv6: added support for AAAA records\r
-\r
- 2015-09-01: Simon Goldschmidt\r
- * task #12178: hardware checksum capabilities can be configured per netif\r
- (use NETIF_SET_CHECKSUM_CTRL() in your netif's init function)\r
-\r
- 2015-08-30: Simon Goldschmidt\r
- * PBUF_REF with "custom" pbufs is now supported for RX pbufs (see pcapif in\r
- contrib for an example, LWIP_SUPPORT_CUSTOM_PBUF is required)\r
-\r
- 2015-08-30: Simon Goldschmidt\r
- * support IPv4 source based routing: define LWIP_HOOK_IP4_ROUTE_SRC to point\r
- to a routing function\r
-\r
- 2015-08-05: Simon Goldschmidt\r
- * many files: allow multicast socket options IP_MULTICAST_TTL, IP_MULTICAST_IF\r
- and IP_MULTICAST_LOOP to be used without IGMP\r
-\r
- 2015-04-24: Simon Goldschmidt\r
- * dhcp.h/c, autoip.h/.c: added functions dhcp/autoip_supplied_address() to\r
- check for the source of address assignment (replacement for NETIF_FLAG_DHCP)\r
-\r
- 2015-04-10: Simon Goldschmidt\r
- * many files: task #13480: added LWIP_IPV4 define - IPv4 can be disabled,\r
- leaving an IPv6-only stack\r
-\r
- 2015-04-09: Simon Goldschmidt\r
- * nearly all files: task #12722 (improve IPv4/v6 address handling): renamed\r
- ip_addr_t to ip4_addr_t, renamed ipX_addr_t to ip_addr_t and added IP\r
- version; ip_addr_t is used for all generic IP addresses for the API,\r
- ip(4/6)_addr_t are only used internally or when initializing netifs or when\r
- calling version-related functions\r
-\r
- 2015-03-24: Simon Goldschmidt\r
- * opt.h, ip4_addr.h, ip4.c, ip6.c: loopif is not required for loopback traffic\r
- any more but passed through any netif (ENABLE_LOOPBACK has to be enabled)\r
-\r
- 2015-03-23: Simon Goldschmidt\r
- * opt.h, etharp.c: with ETHARP_TABLE_MATCH_NETIF== 1, duplicate (Auto)-IP\r
- addresses on multiple netifs should now be working correctly (if correctly\r
- addressed by routing, that is)\r
-\r
- 2015-03-23: Simon Goldschmidt\r
- * etharp.c: Stable etharp entries that are about to expire are now refreshed\r
- using unicast to prevent unnecessary broadcast. Only if no answer is received\r
- after 15 seconds, broadcast is used.\r
-\r
- 2015-03-06: Philip Gladstone\r
- * netif.h/.c: patch #8359 (Provide utility function to add an IPv6 address to\r
- an interface)\r
-\r
- 2015-03-05: Simon Goldschmidt\r
- * netif.c, ip4.c, dhcp.c, autoip.c: fixed bug #37068 (netif up/down handling\r
- is unclear): correclty separated administrative status of a netif (up/down)\r
- from 'valid address' status\r
- ATTENTION: netif_set_up() now always has to be called, even when dhcp/autoip\r
- is used!\r
-\r
- 2015-02-26: patch by TabascoEye\r
- * netif.c, udp.h/.c: fixed bug #40753 (re-bind UDP pcbs on change of IP address)\r
-\r
- 2015-02-22: chrysn, Simon Goldschmidt\r
- * *.*: Changed nearly all functions taking 'ip(X)_addr_t' pointer to take\r
- const pointers (changed user callbacks: raw_recv_fn, udp_recv_fn; changed\r
- port callbacks: netif_output_fn, netif_igmp_mac_filter_fn)\r
-\r
- 2015-02-19: Ivan Delamer\r
- * netif.h, dhcp.c: Removed unused netif flag for DHCP. The preferred way to evaluate\r
- if DHCP is active is through netif->dhcp field.\r
-\r
- 2015-02-19: Ivan Delamer\r

- (see bug #39565)\r
-\r
- 2015-02-16: Claudius Zingerli, Sergio Caprile\r
- * opt.h, dhcp.h/.c: patch #8361 "Add support for NTP option in DHCP"\r

- (note that this is highly unstable yet!)\r
-\r

- still used by sockets, but keeping it private (static) should allow better\r
- compiler optimizations\r
-\r

- - Ported PPP timeout handling to the lwIP timers system\r
- - Disabled all the PPP code using filesystem access, replaced in necessary cases\r
- to configuration variables.\r
- - Disabled all the PPP code forking processes.\r
- - Removed IPX support, lwIP does not support IPX.\r
- - Ported and improved random module from the previous PPP port.\r
- - Removed samba TDB (file-driven database) usage, because it needs a filesystem.\r
- - MS-CHAP required a DES implementation, we added the latest PolarSSL DES\r
- implementation which is under a BSD-ish license.\r
- - Also switched to PolarSSL MD4,MD5,SHA1 implementations, which are meant to be\r
- used in embedded devices with reduced memory footprint.\r
- - Removed PPP configuration file parsing support. \r
- - Added macro definition EAP_SUPPORT to make EAP support optional.\r
- - Added macro definition CHAP_SUPPORT to make CHAP support optional.\r
- - Added macro definition MSCHAP_SUPPORT to make MSCHAP support optional.\r
- - Added macro definition PAP_SUPPORT to make PAP support optional.\r
- - Cleared all Linux syscall calls.\r
- - Disabled demand support using a macro, so that it can be ported later.\r
- - Disabled ECP support using a macro, so that it can be ported later.\r
- - Disabled CCP support using a macro, so that it can be ported later.\r
- - Disabled CBCP support using a macro, so that it can be ported later.\r
- - Disabled LQR support using a macro, so that it can be ported later.\r
- - Print packet debug feature optional, through PRINTPKT_SUPPORT\r
- - Removed POSIX signal usage.\r
- - Fully ported PPPoS code from the previous port.\r
- - Fully ported PPPoE code from the previous port.\r
- - Fully ported VJ compression protocol code from the previous port.\r
- - Removed all malloc()/free() use from PPP, replaced by stack usage or PBUF.\r
- - Disabled PPP server support using a macro, so that it can be ported later.\r
- - Switched all PPP debug to lwIP debug system.\r
- - Created PPP Control Block (PPP PCB), removed PPP unit integer everywhere,\r
- removed all global variables everywhere, did everything necessary for\r
- the PPP stack to support more than one PPP session (pppd only support\r
- one session per process).\r
- - Removed the statically allocated output buffer, now using PBUF.\r
- - Improved structure size of all PPP modules, deep analyze of code to reduce\r
- variables size to the bare minimum. Switched all boolean type (char type in\r
- most architecture) to compiler generated bitfields.\r
- - Added PPP IPv6 support, glued lwIP IPv6 support to PPP.\r
- - Now using a persistent netif interface which can then be used in lwIP\r
- functions requiring a netif.\r
- - Now initializing PPP in lwip_init() function.\r
- - Reworked completely the PPP state machine, so that we don't end up in\r
- anymore in inconsistent state, especially with PPPoE.\r
- - Improved the way we handle PPP reconnection after disconnect, cleaning\r
- everything required so that we start the PPP connection again from a\r
- clean state.\r
- - Added PPP holdoff support, allow the lwIP user to wait a little bit before\r
- reconnecting, prevents connection flood, especially when using PPPoL2TP.\r
- - Added PPPoL2TP LAC support (a.k.a. UDP tunnels), adding a VPN client\r
- feature to lwIP, L2TP being a widely used tunnel protocol.\r
- - Switched all used PPP types to lwIP types (u8t, u16t, u32t, ...)\r
- - Added PPP API "sequential" thread-safe API, based from NETIFAPI.\r

- 2011-07-21: Simon Goldschmidt\r
- * sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes\r
- ioctl/FIONREAD return the size of the next pending datagram.\r
-\r
- 2011-05-25: Simon Goldschmidt\r
- * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c,\r
- combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4\r
- and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP\r
- code so that the code is more readable.\r
-\r
- 2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt)\r
- * nearly the whole stack: Finally, we got decent IPv6 support, big thanks to\r
- Ivan! (this is work in progress: we're just post release anyway :-)\r

- ++ Bugfixes:\r
-\r
- 2016-08-23: Simon Goldschmidt\r
- * etharp: removed ETHARP_TRUST_IP_MAC since it is insecure and we don't need\r
- it any more after implementing unicast ARP renewal towards arp entry timeout\r
-\r
- 2016-07-20: Simon Goldschmidt\r
- * memp.h/.c: fixed bug #48442 (memp stats don't work for MEMP_MEM_MALLOC)\r
-\r
- 2016-07-21: Simon Goldschmidt (patch by Ambroz Bizjak)\r
- * tcp_in.c, tcp_out.c: fixed bug #48543 (TCP sent callback may prematurely\r
- report sent data when only part of a segment is acked) and don't include\r
- SYN/FIN in snd_buf counter\r
-\r
- 2016-07-19: Simon Goldschmidt\r

- * netconn/socket API: fixed bug# 43739 (Accept not reporting errors about\r
- aborted connections): netconn_accept() returns ERR_ABRT (sockets: ECONNABORTED)\r
- for aborted connections, ERR_CLSD (sockets: EINVAL) if the listening netconn\r
- is closed, which better seems to follow the standard.\r
-\r
- 2016-03-23: Florent Matignon\r

-\r
- 2016-03-22: Simon Goldschmidt\r
- * tcp: changed accept handling to be done internally: the application does not\r
- have to call tcp_accepted() any more. Instead, when delaying accept (e.g. sockets\r
- do), call tcp_backlog_delayed()/tcp_backlog_accepted() (fixes bug #46696)\r
-\r
- 2016-03-22: Simon Goldschmidt\r
- * dns.c: ignore dns response parsing errors, only abort resolving for correct\r
- responses or error responses from correct server (bug #47459)\r

- 2016-03-17: Simon Goldschmidt\r
- * api_msg.c: fixed bug #47448 (netconn/socket leak if RST is received during close)\r
-\r
- 2016-03-17: Joel Cunningham\r
- * api_msg.c: don't fail closing a socket/netconn when failing to allocate the\r
- FIN segment; blocking the calling thread for a while is better than risking\r
- leaking a netconn/socket (see bug #46701)\r
-\r
