09f4dee6bc All network drivers! Change pre-processor logic that selects the high priority work queue or gives preferential treatment to the high priority work. All network logic must run on the low priority work queue! Or suffer the consequences. 2018-11-21 07:57:26 -06:00

002f09f2da net/mld: Fix logic error when testing for the case where all members have left. Still does not work. The end result is that the query timer no longer stops.

bfa8c362c6 net/devif/devif_loopback.c: Fix warning: implicit declaration of memcmp. 2018-11-11 11:56:37 -06:00
Gregory Nutt
8a3fc26b74 Squashed commit of the following:
The MLD implementation did not follow the RFC correctly when it is the Querier.  The Querier should use a general query and get query messages from all members of all groups.  This would be driven by a single timer per sub-nset since all groups are queried at once. Instead, the design used a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.

    Similary, the MLDv1 compatibility timer should be a single, separate timer, not a per-group timer.

The Querier should use a general query and get query messages from all members of all groups.  This would be driven by a single timer since all groups are queried at once.  Instead, the design currently uses a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.

68a115aed9 net/icmpv6/icmpv6_autoconfig.c and icmpv6_rnotify.c: Don't take the network device down when reconfiguring only the IP address from within ICMPv6 logic. Recommended by Xiang Xiao in order to avoid the long delays of bringing some networks back up.
Normally it is required that the network be in the "down" state when re-configuring the network interface.  This is thought not to be a necessary here because.

  1. The ICMPv6 logic here runs with the network locked so there can be no outgoing packets with bad source IP addresses from any asynchronous network activity using the device being reconfigured.
  2. Incoming packets depend only upon the MAC filtering.  Network drivers do not use the IP address; they filter incoming packets using only the MAC address which is not being changed here.

net/mld:  Fix a couple of places where I forgot to unlock the network in the previous commit.

    net/mld:  Implement 'Other Querier Present Timer'.  This timer is used to revert to Querier mode if there is no other querier on the network.  Also, fix some naming:  The Done message is not just Version 1 but is used with Version 2 as well.

    net/igmp:  Back out some blind, backported improvements to IGMP from MLD.  There are too many subtle differences in the protocols for this to be safe.

5b7ef856a0 Squashed commit of the following:
net/mld:  The MLD logic now compiles and is much less toxic.  It still is not a proper MLD implementation:  (1) It is basically a port of IGMP, tweaked to work with IPv6 and ICMPv6 MLD messages, (2) it needs a proper analysis and comparison with RFC 3810, and (3) it is completely untested.  For this reason, it will remain EXPERIMENTAL for some time.
    net/mld:  Add some missing macros, more fixes related to IPv6 vs IPv4 types,
    net/mld:  More compilation cleaning.  Most fixups for IPv6 vs IPv4 types.

    net/mld:  Add support for MLD statistics.
    net/mld:  Hook in MLD poll and packet transmission logic.
    net/mld:  Change references to IPv4 definitions to IPv6 definitions; Remove mld_input() since MLD piggybacks on ICMPv6 input.  Add functions to catch MLD messages dispatched by ICMPv6 input logic.
    net/mld:  As a starting point, copy all net/igmp/*.c files to net/mld/. and change all occurrences of igmp (or IGMP) to mld (or MLD).

sched/wqueue/kwork_notifier.c:  Redesign some data structures.  struct works_s must appear at the beginning of the notifier entry structure.  That is because it contains the work queue indices.  This solves a harfault issue.

    net/tcp/tcp_netpoll.c:  tcp_iob_work() needs to free the allocated argument when it is finished.

    net/tcp/tcp_send_buffered.c:  Extend psock_tcp_cansend() so that it also requires that at least on IOB is also avaialble.

    mm/iob:  iob_navail() was returning the number of free IOB chain queue entries, not the number of free IOBs.  Completely misnamed.

    net/tcp/tcp_netpoll.c:  Add logic to receive notifications when IOBs are freed (Needs CONFIG_NET_TCP_WRITE_BUFFERS and CONFIG_IOB_NOTIFIER).  At present, does nothing because the logic in in psock_tcp_cansend() does not check for the availability of IOBs.  That will change.

9d3148406c Signals were not a good choice of IPC to implement the poll function for several reasons: In order to handle the asynchrnous poll-related event, a substantial amount of state information is needed. Signals are only capable of passing minimal amounts of data. There are also complexities with performing kernel space signal handlers in kernel space code that is better to avoid. So, instead of signals, the equivalent logic was converted to run via a callback that executes on the high-priority work queue.
Squashed commit of the following:

    Fix up some final compile isses.

    net/netdev:  Convert the network down notification logic to use the new wqueue-based notification factility.

    net/udp:  Convert the UDP readahead notification logic to use the new wqueue-based notification factility.

    net/tcp:  Convert the TCP readahead notification logic to use the new wqueue-based notification factility.

    mm/iob:  Convert the IOB notification logic to use the new wqueue-based notification factility.

    sched/wqueue:  Signals are not good IPCs to support the target poll functionality for several reasons including the amount of data that can be passed with a signal and in the fact that in protected and kernel modes, user threads executing signal handlers in protected, kernel memory is problematic.  Instead, convert the same logic to perform the notifications via function callback on the high priority work queue.

056d704cf9 This commit brings in a fragmentary, experimental implementation of NETLINK sockets. There is not too much to that socket support on this initial commit, just the netlink socketer framework. However, I decided to bring it into master because there is a enough that I would not want to lose what is in place. And since it is dependent on CONFIG_EXPERIMENATL, its presence on master should be innocuous.
Squashed commit of the following:

    net/netlink:  Mark netlink support as EXPERIMENTAL.
    net/netlink/netlink_sockif.c:  Add netlink_getpeername to the socket interface.
    net:  Add getpeeername() support for netlink sockets.
    include/netpacket/netlink.h:  Add a few more definitions and structures used at the NetLink interface.  Still missing many.
    net/netlink:  Add basic framework for Netlink socket support.

22cd0d47fa This commit attempts remove some long standard confusion in naming and some actual problems that result from the naming confusion. The basic problem is the standard MTU does not include the size of the Ethernet header. For clarity, I changed the naming of most things called MTU to PKTSIZE. For example, CONFIG_NET_ETH_MTU is now CONFIG_NET_ETH_PKTSIZE.
This makes the user interface a little hostile.  People thing of an MTU of 1500 bytes, but the corresponding packet is really 1514 bytes (including the 14 byte Ethernet header).  A more friendly solution would configure the MTU (as before), but then derive the packet buffer size by adding the MAC header length.  Instead, we define the packet buffer size then derive the MTU.

The MTU is not common currency in networking.  On the wire, the only real issue is the MSS which is derived from MTU by subtracting the IP header and TCP header sizes (for the case of TCP).  Now it is derived for the PKTSIZE by subtracting the IP header, the TCP header, and the MAC header sizes.  So we should be all good and without the recurring 14 byte error in MTU's and MSS's.

Squashed commit of the following:

    Trivial update to fix some spacing issues.
    net/: Rename several macros containing _MTU to _PKTSIZE.
    net/: Rename CONFIG_NET_SLIP_MTU to CONFIG_NET_SLIP_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_6LOWPAN_MTU to CONFIG_NET_6LOWPAN_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_ETH_MTU to CONFIG_NET_ETH_PKTSIZE.  This is not the MTU which does not include the size of the link layer header.  This is the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename the file d_mtu in the network driver structure to d_pktsize.  That value saved there is not the MTU.  The packetsize is the memory large enough to hold the maximum packet PLUS the size of the link layer header.  The MTU does not include the link layer header.

a186383f2a Recent changes to UDP in order to correct problems with UDP connection mode introduced a new bug: The 'to' address passed to sendto() must now be NULL in connection mode. But there are errors because there was one place where the 'to' address was still being used.
This commit adds logic to first check for UDP connection mode.  If the UDP socket is connected, then the NULL 'to' address is ignored and saved connection address is used instead.

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().

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.

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.

ae78a925eb Add support for an in-memory routing table cache in order to improve performance when the routing table is retained in a file. The cache holds the most recently used routing table entries and so can eliminate some file access.
Squashed commit of the following:

    net/route:  Flush in cache when any entry is deleted from the routing table.  When a router matching an IP address is found, add the routing table entry to the cache.

    net/route:  Add utility functions to manage an in-memory cache to improve performance when use a file-based routing table.

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.

    net/route: Verify IPv6 ROM route build; Make number of ROM routes a variable, not a configuration item.

    net/route:  Add initial support for ROM-base, read-only routing tables.

    net/route:  Adjust and generalize some structures, rename some functions, and add configuration and build support that will eventually support read-only routing tables.

    net/route:  Some initial though experiments on use of a fixe, read-only routing table

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.
