[1.] One line summary of the problem:
network data corruption (bisected to e5a4b0bb803b)

[2.] Full description of the problem/report:
Note: although my bisect ended at a commit from before 3.19, I have the
same symptom in all newer kernels I've tried, up to 4.6.4.

The commit was:

>commit e5a4b0bb803b39a36478451eae53a880d2663d5b
>Author: Al Viro <viro@zeniv.linux.org.uk>

>    switch memcpy_to_msg() and skb_copy{,_and_csum}_datagram_msg() to primitives

The symptom is that downloaded files (http, ftp, and probably other
protocols) have small corrupted segments (about 1-2 kilobytes long) in
random locations. Only downloads that sustain a high speed for at least a
few seconds are corrupted. Anything small enough to be received in less
than about 5 seconds is not affected.

If I download the same file twice in a row, the corruption is in different
places in each copy.

If I try to do a git clone, it fails a few seconds into the "Receiving
objects" stage with a deflate error.

[3.] Keywords: networking, carl9170

[4.] Kernel information
[4.1.] Kernel version (from /proc/version):
Multiple versions are known to be affected, from 3.19 to 4.6.4

[4.2.] Kernel .config file:
For testing I built with make x86_64_defconfig followed by enabling the
carl9170 driver, which adds these lines:
CONFIG_ATH_COMMON=m
CONFIG_ATH_CARDS=m
CONFIG_CARL9170=m
CONFIG_CARL9170_LEDS=y
CONFIG_CARL9170_WPC=y

[5.] Most recent kernel version which did not have the bug:
That would be the predecessor of e5a4b0bb803b39a36478451eae53a880d2663d5b
which is v3.18-rc6-1620-g17836394e578

[6.] no Oops

[7.] A small shell script or example program which triggers the
     problem (if possible)

This command fails reliably for me when running an affected kernel:

git clone git://git.kernel.org/pub/scm/git/git.git

(I'm including all the standard format stuff suggested by REPORTING-BUGS,
but I think you can skip from here to section 8.7 without missing anything
relevant)

[8.3.] Module information (from /proc/modules):

When I tested with the x86_64_defconfig + carl9170 kernel, there were
hardly any modules built, and I reproduced the problem after booting with
init=/bin/sh, so no unnecessary modules were loaded. Currently running a
normal 4.6.4 kernel which is showing the bug, there are many more modules:
