With 2.4.21 I get:
$ patch -p1 < mm.patch
patching file mm/mmap.c
Hunk #1 FAILED at 1041.
1 out of 1 hunk FAILED -- saving rejects to file mm/mmap.c.rej
In mmap.c.rej I find:
**************
*** 1041,1046 ****
if (!len)
return addr;
/*
* mlock MCL_FUTURE?
*/
--- 1041,1049 ----
if (!len)
return addr;
+ if ((addr + len) > TASK_SIZE || (addr + len) < addr)
+ return -EINVAL;
+
/*
* mlock MCL_FUTURE?
*/
What am I doing wrong?
