Subject: [PATCH] linux-user: use target_ulong
|
|
|
|
Linux syscalls pass pointers or data length or other information of that sort
|
|
to the kernel. This is all stuff you don't want to have sign extended.
|
|
Otherwise a host 64bit variable parameter with a size parameter will extend
|
|
it to a negative number, breaking lseek for example.
|
|
|
|
Pass syscall arguments as ulong always.
|
|
|
|
