From: Ivan Kokshaysky Date: Thu, 24 Apr 2008 12:54:50 +0000 (+0400) Subject: alpha: unbreak OSF/1 (a.out) binaries X-Git-Tag: v2.6.26-rc1~1091 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2444e56b0c08e6f3e3877583841a1213e3263d98;p=linux-2.6 alpha: unbreak OSF/1 (a.out) binaries OSF/1 brk(2) was broken by following one-liner in sys_brk() (commit 4cc6028d4040f95cdb590a87db478b42b8be0508): - if (brk < mm->end_code) + if (brk < mm->start_brk) goto out; The problem is that osf_set_program_attributes() does update mm->end_code, but not mm->start_brk, which still contains inappropriate value left from binary loader, so brk() always fails.
