| |
Hi, couple of things stopped working on my box where I have /dev/vc/XX as symlinks to /dev/ttyXX, and some things use /dev/vc/XX and some /dev/ttyXX. After last update hour ago things which use /dev/vc/XX stopped working for non-root - they now fail with EACCES error if they attempt to redirect its input or output through '>' or '<>' bash redirection operators:
$ touch /tmp/xx $ ln -s /tmp/xx yy $ cat > yy -bash: yy: Permission denied
Strace says:
[pid 3268] open("yy", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = -1 EACCES (Permission denied)
This command succeeds on kernel from thursday. Simillar problem is that
$ rm /tmp/xx $ ln -s /tmp/xx yy $ cat > yy -bash: yy: No such file or directory
while it creates /tmp/xx file on older kernels.
Currently I suspect Trond's LOOKUP_CONTINUE change in '[PATCH] Add open intent information to the 'struct nameidata', but I did not tried reverting it yet to find whether it is culprit or no. But other changes than these four from Trond looks completely innocent. Thanks, Petr Vandrovec vandrove@vc.cvut.cz
