From 81bbe906c89b6b7af58a1eeb96ec5a0bfdc3386f Mon Sep 17 00:00:00 2001 From: "takasi-y@ops.dti.ne.jp" Date: Mon, 12 Apr 2010 04:07:35 +0900 Subject: linux-user: rlimit conversion between host and target. rlim_t conversion between host and target added. Otherwise there are some incorrect case like - RLIM_INFINITY on 32bit target -> 64bit host. - RLIM_INFINITY on 64bit host -> mips and sparc target ? - Big value(for 32bit target) on 64bit host -> 32bit target. One is added into getrlimit, setrlimit, and ugetrlimit. It converts both RLIM_INFINITY and value bigger than target can hold(>31bit) to RLIM_INFINITY. Another one is added to guest_stack_size calculation introduced by 703e0e89. The rule is mostly same except the result on the case is keeping the value of guest_stack_size. Slightly tested for SH4, and x86_64 -linux-user on x86_64-pc-linux host.
