Hi,
The commit entitled "tcp: reduce out_of_order memory use" turns out to cause
problems with a number of USB drivers.
The first one called to my attention was for staging/r8712u. For this driver,
there are problems with SSL communications as reported in
https://bugzilla.redhat.com/show_bug.cgi?id=847525.
Other drivers including rtl8187, rtl8192cu and rt2800usb cannot connect to a
WPA1- or WEP-encrypted AP, but work fine with WPA2. The rtl8192cu problem is
reported in https://bugzilla.kernel.org/show_bug.cgi?id=46171.
I find it hard to understand why this patch should cause these effects; however,
I have verified that a kernel generated from "git checkout e86b2919" works fine.
This commit is immediately before the patch in question.
Note, this patch was applied during the merge between 3.3 and 3.4. The
regression has been undiscovered for some time.
Any help on this problem will be appreciated.
Larry
