Hi All, I have implemented a new entry in proc directory in kernel 2.6.1. It is something similar to /proc/pid/maps. The new entry is /proc/pid/smaps where pid is the process id. It is working well on kernel 2.6.1. I decided to upgrade it to kernel 2.6.9, but something is going wrong when I type de cat command. $ cat /proc/3477/smaps b68ed000-b68ee000 rw-p /usr/lib/kde3/kded_kinetd.so VmRss: 4 kB VmData: 0 KB VmStk: 0 kB VmExe: 0 kB VmLib: 0 kB Shared: 0 kB Private: 4 kB Shareable: 0 kB b68ee000-b68ff000 r--p /usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf VmRss: 68 kB VmData: 0 KB VmStk: 0 kB VmExe: 0 kB VmLib: 0 kB Shared: 0 kB Private: 68 kB Shareable: 0 kB .... b7fea000-b8000000 r-xp /lib/ld-2.3.2.so VmRss: 80 kB VmData: 0 KB VmStk: 0 kB VmExe: Segmentation fault As you can see, the segmentation fault is displayed at the end of the output. This problem does not have for kernel 2.6.1. The files I changed are fs/proc/base.c and fs/proc/task_mmu.c on kernel 2.6.1. AFAIK this files were not changed since 2.6.1. So what is going on with kernel 2.6.9? BR, Mauricio Lin. ===== ************************************************ Conhecimento vem do seu instrutor; Sabedoria vem do seu interior.
