5c5c08efcd network: simplify the timeout process logic
1.Consolidate absolute to relative timeout conversion into one place(_net_timedwait)
2.Drive the wait timeout logic by net_timedwait instead of devif_timer
This patch help us remove devif_timer(period tick) to save the power in the future.

5fb5a9dfdd psock_udp_sendto should call udp_wrbuffer_tryalloc for nonblock socket (#20)
net/udp/udp_wrbuffer.c:  Add new function udp_wrbuffer_tryalloc()
net/udp/udp_psock_sendto_buffered.c:  If the socket was opened with O_NONBLOCK, then use udp_wrbuffer_tryalloc() so that the caller will not wait for a write buffer.  Return EGAIN if udp_wrbuffer_tryalloc() failes.

Author: Gregory Nutt <gnutt@nuttx.org>

    Run all .h and .c files modified in last PR through nxstyle.

Author: Xiang Xiao <xiaoxiang@xiaomi.com>

    Net cleanup (#17)

    * Fix the semaphore usage issue found in tcp/udp

    1. The count semaphore need disable priority inheritance
    2. Loop again if net_lockedwait return -EINTR
    3. Call nxsem_trywait to avoid the race condition
    4. Call nxsem_post instead of sem_post

    * Put the work notifier into free list to avoid the heap fragment in the long run.  Since the allocation strategy is encapsulated internally, we can even refine the implementation later.

    * Network stack shouldn't allocate memory in the poll implementation to avoid the heap fragment in the long run, other modification include:

    1. Select MM_IOB automatically since ICMP[v6] socket can't work without the read ahead buffer
    2. Remove the net lock since xxx_callback_free already do the same thing
    3. TCP/UDP poll should work even the read ahead buffer isn't enabled at all

    * Add NET_ prefix for UDP_NOTIFIER and TCP_NOTIFIER option to align with other UDP/TCP option convention

    * Remove the unused _SF_[IDLE|ACCEPT|SEND|RECV|MASK] flags since there are code to set/clear these flags, but nobody check them.

70404ed0dc Merged in antmerlino/nuttx/iobinstrumentation (pull request #1001)
Iobinstrumentation

* mm/iob: Introduces producer/consumer id to every iob call. This is so that the calls can be instrumented to monitor the IOB resources.

* iob instrumentation - Merges producer/consumer enumeration for simpler IOB user.

* fs/procfs: Starts adding support for /proc/iobinfo

* fs/procfs: Finishes first pass of simple IOB user stastics and /proc/iobinfo entry

69056d4053 net/: The value ERROR should never be returned from internal OS functions. That is reserved for returning values to appliations with the errno value set. Within the OS, errors are returned with a negated errno value ALWAYS. 2019-02-14 15:38:36 -06:00

427b3b8fcb Squashed commit of the following:
net/utils:  return from net_breaklock() was being clobbered.
    net/:  Replace all calls to iob_alloc() with calls to net_ioballoc() which will release the network lock, if necessary.
    net/utils, tcp, include/net:  Separate out the special IOB allocation logic and place it in its own function.  Prototype is available in a public header file where it can also be used by network drivers.
    net/utils: net_timedwait() now uses new net_breaklock() and net_restorelock().

fef255e5be This commit adds an as-of-yet untested implemented of UDP write buffering.
Squashed commit of the following:

    net/udp:  Address most of the issues with UDP write buffering.  There is a remaining issue with handling one network going down in a multi-network environment.  None of this has been test but it is certainly ready for test.  Hence, the feature is marked EXPERIMENTAL.
    net/udp:  Some baby steps toward a corrected write buffering design.
    net/udp:  Remove pesky write buffer macros.
    Eliminate trailing space at the end of lines.
    net/udp:  A little more UDP write buffering logic.  Still at least on big gaping hole in the design.
    net/udp:  Undefined CONFIG_NET_SENDTO_TIMEOUT.
    net/udp:  Crude, naive port of the TCP write buffering logic into UDP.  This commit is certainly non-functional and is simply a starting point for the implementatin of UDP write buffering.
    net/udp:  Rename udp/udp_psock_sendto.c udp/udp_psock_sendto_unbuffered.c.
