Subject: [BUG report] net.core.rmem_default is larger than net.core.rmem_max
Date: Fri, 27 Apr 2012 17:31:22 +0800 [thread overview]
Message-ID: <4F9A676A.8070406@gmail.com> (raw)
It's unconventional that "default" value is greater than "max". :-(
net.core.rmem_max = 131071
net.core.rmem_default = 229376
net.core.wmem_max = 131071
net.core.wmem_default = 229376
And bisect the code to find the following commit caused this phenomenon.
This patch increase SK_WMEM_MAX and SK_RMEM_MAX which are used to
initialize them.
But rmem_max and wmem_max value are still be covered according the RAM size
in sk_init().
87fb4b7b533073eeeaed0b6bf7c2328995f6c075 is the first bad commit
commit 87fb4b7b533073eeeaed0b6bf7c2328995f6c075
