fb8cf9373c net/udp: Resolve race condition in connection-less UDP sockets with read-ahead buffering.
In connection-mode UDP sockets, a remote address is retained in the UDP connection structure.  This determines both there send() will send the packets and which packets recv() will accept.

This same mechanism is used for connection-less UDP sendto:  A temporary remote address is written into the connection structure to support the sendto() operation.  That address persists until the next recvfrom() when it is reset to accept any address.

When UDP read-ahead buffering is enabled, however, that means that the old, invalid remote address can be left in the connection structure for some time.  This can cause read-ahead buffer to fail, dropping UDP packets.

Shortening the time between when he remote address is reset (i.e., immediately after the sendto() completes) is not a solution, that does not eliminate the race condition; in only makes it smaller.

With this change, a flag was added to the connection structure to indicate if the UDP socket is in connection mode or if it is connection-less.  This change effects only UDP receive operations:  The remote address in the UDP connection is always ignored if the UDP socket is not in connection-mode.

No for connection-mode sockets, that remote address behaves as before.  But for connection-less sockets, it is only used by sendto().

091e3f732e net/udp: Fix several issues using connected UDP sockets: sendto() should not accept and address. Normally send() should be used instead. recvfrom() is no longer necessary. recvfrom() and poll() should not reset to accept any addresses but should, instead, only accept inputs and events from the connected remore peer. On of these issues was noted by 李桂丁 <liguiding@pinecone.net>.

    wireless/bluetooth:  Some small changes that gets to a clean compile by just eliminating some incorrect implementations (still with a lot of warnings.  The logic is still incomplete but now not so lethal.
    wireless/bluetooth:  Restructuring:  Connection interfaces should internal to wireless/bluetooth.  include/nuttx/wireless/bt_conn.h removed and merged with wireless/bluetooth/bt_conn.h.  Several fix to get closer to bt_netdev.c compiling.  Need to design some not interfaces and use some existing interfaces to send and receiv packets.
    wireless/bluetooth: Some organization with some network device compile errors fixed.  Still not even close to compiling.
    net/bluetooth:  Fix numerous compile issues; Still open design issues with regard to the interface with the Bluetooth stack.
    wireless/bluetooth:  Create bt_netdev.c with a crude copy of mac802154_netdev.c.  Does not not even compile yet.

Fix SMP related bugs

* sched/sched: Fix a deadlock in SMP mode

    Two months ago, I introduced sched_tasklist_lock() and
    sched_tasklist_unlock() to protect tasklists in SMP mode.
    Actually, this change works pretty well for HTTP audio
    streaming aging test with lc823450-xgevk.

    However, I found a deadlock in the scheduler when I tried
    similar aging tests with DVFS autonomous mode where CPU
    clock speed changed based on cpu load. In this case, call
    sequences were as follows;

    cpu1: sched_unlock()->sched_mergepending()->sched_addreadytorun()->up_cpu_pause()
    cpu0: sched_lock()->sched_mergepending()

    To avoid this deadlock, I added sched_tasklist_unlock() when calling
    up_cpu_pause() and sched_addreadytorun(). Also, added
    sched_tasklist_lock() after the call.

21041af8a7 This commit modifies the Unix domain local socket design. Local sockets are built on top of pipes. The Local socket implementation maintained file descriptors to interrupt with the pipes. File descriptors have the bad property that they are valid only while running on the thread within the task that created the local socket.
As a policy, all internal OS implementations must use "detached" files which are valid in any context and do not depend on the validity of a file descriptor at any point in time.  This commit converts the usage of file descriptors to detached files throughout the local socket implementation.

Squashed commit of the following:

    net/local: Finish change to eliminate use of file descriptors.
    net/local:  A little more of the conversion.
    net/local: Beginning of chnages to eliminate use of file descriptors in the local socket implementeation. poll() will be a problem.

14fb37c995 Merged in antmerlino/nuttx/sixlowpan-mac802154 (pull request #526)
ieee802154: Simplifies notify() and rxframe() calls to a single notify() call. dataind's and all other "notifs" are now "primitives" which aligns with standard terminology

* mac802154: Adds missing breaks from case statement

* sixlowpan: Fixes bad logic where ACK is not requested if address is not a broadcast

* ieee802154: Simplification of "notifs" and "datainds" to generic primitives passed via a single notify call to the layer above the MAC

* Directories.mk should reference CONFIG_WIRELESS instead of CONFIG_DRIVERS_WIRELESS

* xbee_netdev: Network must be locked when calling sixlowpan_input

* sixlowpan: Reassembly buffer can't be freed if provided by radio driver

* sixlowpan: Don't free IOB if there is an error processing it as the MAC will try to pass it along to another receiver

* ieee802154: Adds basic logging to ieee802154_primitive.c

* Minor fixes after rebase

* xbee: Adds AT query timeout to retry if XBee doesn't respond to request

* same70-xplained: Adds Xbee support. Makes mikroBus slot Kconfig 'choice'

* mac802154: Removes unused function declaration

* drivers/mrf24j40: Fixes compilation error using . operator rather than -> operator

* mac802154_device: Changes a few mac802154_primtive_free's to ieee802154_primitive_free() and changes notif to primitive in a couple places.

* mac802154: Adds promiscous mode logic to bypass parsing of incoming frames. MAC char device also checks for promiscous mode and passes whole frames including header and FCS to the application if promiscous mode is enabled.

* sixlowpan: Fixes logic to correctly check if packet is large enough to include header.  This would cause packets to be considered too small when they are sufficiently sized.

* sixlowpan: Fixes forwarding logic to use forwarding device rather than received device to look up destination link layer address

* net/ipforward: Fixes typo that caused build error when IP forwarding was enabled with CONFIG_NET_ICMPv6_NEIGHBOR enabled as well.

* configs/same70-xplained: Simple spelling fix

cf5cba953d There was a possible recursion that could eventually overflow the stack. The error occurred when closing the socket with inet_close() while a socket callback was still queued. When the socket callback was executed by devif_conn_event(), this resulted in a call to psock_send_eventhandler() with TCP_CLOSE flag set which then called tcp_lost_connection(). tcp_shutdown_monitor() then called tcp_callback() again, which again called psock_send_eventhandler(), and so on.... Noted by Pascal Speck. Solution is also similar to a solution proposed by Pascal Speck. 2017-10-19 11:55:51 -06:00

bc40403516 There was a reference counting problem in the TPC logic of net_clone(). net_clone() which is the common logic underlying dup() and dup2() for sockets. When net_clone() calls net_start_monitor() and net_start_monitor() returns a failure (because the underlying TCP connection) then net_clone() must back out the reference count on the structure. Problem noted by Pascal Speck and this implementation of the solution is based on his suggestion. 2017-10-19 11:09:23 -06:00

9568600ab1 Squashed commit of the following:
This commit backs out most of commit b4747286b1.  That change was added because sem_wait() would sometimes cause cancellation points inappropriated.  But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.

    In the OS, all calls to sem_wait() changed to nxsem_wait().  nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.

    In all OS functions (not libraries), change sem_wait() to nxsem_wait().  This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.

    sched/semaphore:  Add the function nxsem_wait().  This is a new internal OS interface.  It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.

44d88abb83 This commit adds support for routing tables in files in a file system. This might be useful for customized, per-unit routing tables.
There are two issues with it however:

1. Reading from file system on a per packet basis could be slow.  I think it probably should have a small, in-memory cache of most frequently used routes for good problem.

2. Currently the delroute logic is disabled due to a problem with the design.  NuttX does not currently support truncate().  Therefore, it is not possible to delete entries from the routing table file.

In this current implementation, that leaves the last entry intact at the end of the file.  An alternative design might include a tag on each record to indicate if the record is valid or not.  That would work but would add complexity to the other routing table functions.

The existing implementation is available for testing purposes only if CONFIG_EXPERIMENTAL=y.

Squashed commit of the following:

    net/route:  The current delroute design depends on file truncation.  However, NuttX does not currently support truncate.  Alternative, more complex designs are possible but not implemented.  At present the file routing table are otherwise functional but the delroute logic is disabled via CONFIG_EXPERIMENTAL.  Enable it only if you plan to fix it.

    net/route:  Fix some issues with locking routing table files.

    net/route:  Add partial implementation of delroute for the case where the routing table is in a file.

    net/route:  Add support for seeking to positions in the routing table.

    net/route: Add net_addroute_ipv4/6() using a file-based routing table.

    net/route: Add net_foreach_ipv4/4() using a file-based routing table.

    net/route:  Initial build, configuration, and fs utilies to support routing tables in a file.

3aa18ef56e Addes support for read-only routing tables. Prior to this change, routing tables were only support in RAM and had to be initialized with explicit logic to add the necessary routes to the routing table. With this change, routes may be defined in the pre-initialized, read-only routing table provided by the board-specific logic
This would be particularly useful, for example, in the case where there is only a single network adaptor and you want all output packets to go to the single adaptor in all cases.  So for that behavior you could add a read-only routing table to the board-specific long that contains a single entry, the default route: 0.0.0.0/0.

Squashed commit of the following:

    net/route:  RAM and ROM routing tables build correctly in all IPv4 and IPv6 configurations.

Subject: [PATCH] ICMPv6: fix router advertisement

Fixes several errors preventing icmpv6_radvertise.c from being compiled. Fixes conversions to network byte order (namely vlifetime, plifetime, mtu).

IPv6 source address is set to link-local IP address instead of the address in the netdev structure. This is in compliance to RFC 4861. RA didn't work on Linux before this change.

Finally, router prefix and prefix length are derived from the IPv6 address and netmask in the netdev structure. This seems to make more sense than using a predefined, separate prefix from the config.

88a87f8e3f 6LoWPAN: The original, Contiki-based design used only a single buffer for reassemblying larger packets. This could be a problem issue for hub configurations which really need the capability concurrently reassemble multiple incoming streams concurrently. These was also a design issue in that the reassembly buffer could be corrupted by outgoing packets. The design was extended to support multiple reassembly buffers, each associated with the reassembly tag and source address. This assures that there can be be no corruption of the reassembly once it has started. 2017-08-26 10:00:47 -06:00

    We discovered a problem with the samv7 mcan driver which results, under some circumstances, in a very high CPU load.

    The problem occurs, and is easily reproducible, if the device is connected to a CAN network with a wrongly configured CAN speed (baud rate). In our tests we set the CAN speed of the device to 1000000 and the speed of the other CAN nodes to 500000. The device is restarted and sends a CANopen “bootup message” to the CAN network. This results in huge amount of errors messages on the CAN bus, probably because of the CAN feature for acknowledging error messages. The error messages can’t be read by the device because of the misconfigured CAN speed, instead the CAN chip reports lots of errors, which are reported to the application which uses the CAN driver (CONFIG_CAN_ERRORS is enabled).

    The CAN errors are reported from the CAN chip via interrupts and thus the interrupt load is very high in this scenario. To fix the problem the driver now disables each RX error interrupt after it is occurred. The RX error interrupts are turned back on if at least one CAN message is received successfully.

    We discovered a problem with the samv7 mcan driver which results, under some circumstances, in a very high CPU load.

    The problem occurs, and is easily reproducible, if the device is connected to a CAN network with a wrongly configured CAN speed (baud rate). In our tests we set the CAN speed of the device to 1000000 and the speed of the other CAN nodes to 500000. The device is restarted and sends a CANopen “bootup message” to the CAN network. This results in huge amount of errors messages on the CAN bus, probably because of the CAN feature for acknowledging error messages. The error messages can’t be read by the device because of the misconfigured CAN speed, instead the CAN chip reports lots of errors, which are reported to the application which uses the CAN driver (CONFIG_CAN_ERRORS is enabled).

    The CAN errors are reported from the CAN chip via interrupts and thus the interrupt load is very high in this scenario. To fix the problem the driver now disables each RX error interrupt after it is occurred. The RX error interrupts are turned back on if at least one CAN message is received successfully.
