1c002e1049 fs/vfs/fs_fstat: Correct fstat() for proxied block and MTD drivers.
Block and MTD drivers may be opened and managed as though they were character drivers.  But this is really sleight of hand; there is a hidden character driver proxy that mediates the interface to the block and MTD drivers in this case.

fstat(), however, did not account for this.  It would report the characteristics of the proxy character driver, not of the underlying block or MTD driver.

This change corrects that.  fstat now checks if the character driver is such a proxy and, if so, reports the characteristics of the underlying block or MTD driver, not the proxy character driver.

efe65749ce Fix condition logic: The setup seems to support a network without sockets. That is not the case.
Squashed commit of the following:

    sched/sched/sched_getsockets.c:  Fix an error in conditional compilation.
    fs/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    Documentation/:  Remove all references to CONFIG_NSOCKET_DESCRIPTORS == 0
    include/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    libs/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    net/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    sched/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    syscall/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    tools/:  Fixups for CONFIG_NSOCKET_DESCRIPTORS no longer used to disable sockets.

f5d0fc7447 fs/vfs and net/udp: Repartition logic of commit 0c963449d6, moving into net/udp. Add support to handle connected UDP sockets. The correct 'optimal blksize' to return is the MSS. The MTU is always too big. 2018-04-27 08:36:25 -06:00
