8cfb376f81 net/mld: There is an issue with the general query timer design. There should be a single instance, not a per-group instance of the timer (ditto for the v1 compatibility timer). Fall back for now and use the per-group MAX query. 2018-11-10 12:13:54 -06:00

854046a931 /net/devif/ipv6_input.c: Correct handling of IPv6 extension headers. The main confusion was that the payload length in the IPv6 header does not include its extension headers.
net/icmpv6/icmpv6_input.c:  Correct caculation of the ICMPv6 header address
    net/mld/mld_query.c:  Correct back test for group found.
    net/mld/mld_report.c: Fix host vs. network order problem.
    net/mld/mld_send.c: Correct the address used in sending the General Query.  It should be the unspecified address in that case.
    net/mld:  Querying workaround.  The MLD implementation does not follow the RFC correct 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 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.

a7fd58c4db Squashed commit of the following:
many locations:  Change occurences of open() followed by file_detach() to file_open().  Change most non-controversion calls to open() to nx_open().

    fs/inode/fs_fileopen.c:  Flesh out file_open() with some interim, placeholder logic.

    fs/inode/fs_fileopen.c:  Add a framework for a file_open() implementation (no real logic in place yet).

    fs/vfs/fs_open.c:  Add nx_open() which is the same as open() except that it does not create a cancellation point nor does it modify the errno variable.

a7265d71c6 This commit adds support for default signal actions for SIGSTOP, SIGSTP, and SIGCONT.
Squashed commit of the following:

    Add procfs support to show stopped tasks.  Add nxsig_action() to solve a chicken and egg problem:  We needed to use sigaction to set default actions, but sigaction() would refuse to set actions if the default actions could not be caught or ignored.

    sched/signal:  Add configuration option to selectively enabled/disable default signal actions for SIGSTOP/SIGSTP/SIGCONT and SIGKILL/SIGINT.  Fix some compilation issues.

    sched/sched:  Okay.. I figured out a way to handle state changes that may occur while they were stopped. If a task/thread was already blocked when SIGSTOP/SIGSTP was received, it will restart in the running state.  I will appear that to the task/thread that the blocked condition was interrupt by a signal and returns the EINTR error.

    sched/group and sched/sched:  Finish framework for continue/resume logic.

    sched/signal:  Roughing out basic structure to support task suspend/resume

    sched/sched:  Internal functions sched_reprioritize() and sched_setpriority() no longer movidify the errno value.  Also renamed to nxsched_reprioritize() and sched_setpriority().

    sched/sched:  Add new internal OS function nxsched_getparam() that is identical to sched_getparam() except that it does not modify the errno value (actually, the previous value erroneously neglected to set the errno value to begin with, but this fixes both issues).  All usage of sched_getparam() within the OS is replaced with nxsched_getparam().

7deb24484c This comment converts the underlying IPC used by the UserFS from Unix domain local sockets to UDP LocalHost loopback sockets. The problem with the local sockets is that they do require operations on the top level psuedo-file system inode tree. That tree must be locked during certain traversals such as enumerate mountpoints or enumerating directory entries.
This conversion is unfortunate in the sense that Unix local domain sockets are relatively lightweight.  LocalHost UDP sockets are much heavier weight since they rely on the full UDP stack.  If anyone is up for a complete redesign, then using some shared memory and a POSIX message queue would be lightweight again.

This commit also fixes several bugs that were not testable before the inode tree deadlock.  I cannot say that the logic is 100% stable but it does not have basic functionality.

Squashed commit of the following:

    fs/userfs:  Order locking so that access to the shared I/O buffer is also locked.
    fs/userfs:  Converts to use LocalHost UDP loopback for IPC.

70c59a9d91 This commit adds support for semi-standard IPPROTO_ICMP6 sockets. This is a replacement for the non-standard ICMPv6 ping support that violated the portable POSIX OS interface.
Squashed commit of the following:

    net/icmpv6: IPPROT_ICMP6 socket logic now builds without error.
    net/icmpv6:  Add support for read-ahead and poll(). Initial commit is just cloned from ICMP with the appropriate name changes.
    configs/:  All defconfig filess that include CONFIG_NET_ICMPv6_SOCKET=y need to select CONFIG_SYSTEM_PING6=y and deselect CONFIG_DISABLE_POLL.
    Update NSH documention to show that ping6 is now a built in command.
    net/icmpv6:  Add icmpv6_sendto.c and icmpv6_recvfrom.c.  Initial versions are just clones from icmp/ with appropriate name changes.
    net/icmpv6:  Clone some ICMP socket logic as the beginning of support for ICMPv6 socket support.
    Rename CONFIG_NET_ICMPv6_PING to CONFIG_NET_ICMPv6_SOCKET.  Move prototype for icmpv6_ping from include/nuttx/net/icmpv6 to net/icmpv6/icmpv6.h

cccc86da09 This change adds support for semi-standard IPPROTO_ICMP AF_INET datagram sockets. This replaces the old ad hoc, nonstandard way of implementing ping with a more standard, socket interface.
Squashed commit of the following:

    net/icmp:  Finishes off icmp_recvfrom().
    net/icmp:  Add readahead support for IPPROTO_ICMP sockets.
    net/icmp:  Add poll() support for IPPROTO_ICMP sockets.
    net/icmp:  Add a connection structure for IPPROTO_ICMP sockets.
    net/icmp:  Implements sendto for the IPPROTO_ICMP socket.
    net/icmp:  Move icmp_sendto() and icmp_recvfrom() to separate files.  They are likely to be complex (when they are implemented).
    net/icmp:  Hook IPPROTO_ICMP sockets into network.  Fix some naming collisions.  Still missing basic ICMP send/receive logic.
    configs: apps/system/ping current need poll() enabled.
    configs: All defconfig files that use to enable low-level support must now enabled CONFIG_SYSTEM_PING.

5b04c25dcd drivers/serial/tcdrain: tcdrain() was recently added to the NuttX C library. But there is a problem. The specification of tcdrain() requires that it be a cancellation point. In order to do this, tcdrain was moved from the C library into the OS and the addition cancellation point hooks were added. In non-FLAT builds, access via system calls is also now supported. 2017-10-06 10:55:36 -06:00
Gregory Nutt
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.
