| |
I have found a bug in NFSv2.
[root@igor /tmp]# mount igor:/u u [root@igor /tmp]# cd u [root@igor u]# umask 000 [root@igor u]# ls -l q ls: q: File o directory inesistente [root@igor u]# touch q [root@igor u]# ls -l q -rw-r--r-- 1 root root 0 lug 13 07:56 q
This seems to be caused by use of unitialized current->fs->umask via vfs_create called by nfsd_create.
Patch for 2.4.6 follows.
