a680553f35 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. 2018-09-12 06:40:18 -06:00

3bf96c8e7e net/arp: Improve arp_find() commit 9774d35010 to reduce the amount and frequency of data copies. 2018-08-25 07:12:21 -06:00
Gregory Nutt
9774d35010 net/arp: Make the function arp_find() thread-safe. It now returns a copy of the ARP table entry, rather than a potentially unstable reference to the ARP table entry. 2018-08-24 17:36:08 -06:00

c065f0fd49 net/tcp: tcp_send_[un]buffered.c: Check routing table in psock_send_addrchck(). Previously only ARP table was considered when determining if the data will actually be sent. 2018-02-22 16:24:15 -06:00

e0142f1d52 net/tcp: Fixed bad return value handling in psock_tcp_send(). send() expects psock_tcp_send() to return a negated errno value, not -1 with the errno set (GN: I added same change for tcp_send_buffered.c which has the same issue as tcp_send_unbuffered.c) 2018-02-13 08:02:42 -06:00

42a0796615 Squashed commit of the following: 
sched/semaphore:  Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable.  Changed all references to sem_post in the OS to nxsem_post().

    sched/semaphore:  Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable.  Changed all references to sem_destroy() in the OS to nxsem_destroy().

    libc/semaphore and sched/semaphore:  Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable.  Changed all references to sem_setprotocol in the OS to nxsem_setprotocol().  sem_getprotocol() was not used in the OS

83cdb0c552 Squashed commit of the following: 
libc/semaphore:  Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable.  Changed all references to sem_getvalue in the OS to nxsem_getvalue().

    sched/semaphore:  Rename all internal private functions from sem_xyz to nxsem_xyz.  The sem_ prefix is (will be) reserved only for the application semaphore interfaces.

    libc/semaphore:  Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable.  Changed all references to sem_init in the OS to nxsem_init().

    sched/semaphore:  Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.

    sched/semaphoate:  Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.

24767a0c66 Fixes for problems found by Coverity in the nuttx repository: 
net/socket/recvfrom.c: Check fromlen integrity before using it.

    net/socket/net_sockets.c: Always check for valid psock before using.

    net/tcp/tcp_send_unbuffered.c:  Avoid using psock beforing checking its integrity.

    sched/timer/timer_create.c: Fix watchdog resource leak if cannot allocate a new timer.

04ad162540 Networking: Clean up some naming that has bothered me for a long time... There are no interrupts and no interrupt handlers in the network. There are events and event handler (there used to to be interrupt logic in there years ago but that is long, long gone). 2017-08-29 14:08:04 -06:00
