compat_ioctl: Supress "unknown cmd" message on serial /dev/console

2010-01-20T23:03:26+00:00

After the commit fb07a5f8 ("compat_ioctl: remove all VT ioctl
handling"), I got this error message on 64-bit mips kernel with 32-bit
busybox userland:

ioctl32(init:1): Unknown cmd fd(0) cmd(00005600){t:'V';sz:0} arg(7fd76480) on /dev/console

The cmd 5600 is VT_OPENQRY.  The busybox's init issues this ioctl to
know vt-console or serial-console.  If the console was serial console,
VT ioctls are not handled by the serial driver.

And by quick search, I found some programs using VT_GETMODE to check
vt-console is available or not.

ecryptfs: use after free

2010-01-20T04:36:06+00:00

The "full_alg_name" variable is used on a couple error paths, so we
shouldn't free it until the end.

ecryptfs: Eliminate useless code

2010-01-20T04:36:05+00:00

The variable lower_dentry is initialized twice to the same (side effect-free)
expression.  Drop one initialization.

A simplified version of the semantic match that finds this problem is:
(http://coccinelle.lip6.fr/)

// 
@forall@
idexpression *x;
identifier f!=ERR_PTR;
@@

x = f(...)
... when != x
(
x = f(...,<+...x...+>,...)

ecryptfs: pass matching flags to interpose as defined and used there

2010-01-20T04:36:02+00:00

ecryptfs_interpose checks if one of the flags passed is
ECRYPTFS_INTERPOSE_FLAG_D_ADD, defined as 0x00000001 in ecryptfs_kernel.h.
But the only user of ecryptfs_interpose to pass a non-zero flag to it, has
hard-coded the value as "1". This could spell trouble if any of these values
changes in the future.

ecryptfs: remove unnecessary d_drop calls in ecryptfs_link

2010-01-20T04:36:00+00:00

Unnecessary because it would unhash perfectly valid dentries, causing them
to have to be re-looked up the next time they're needed, which presumably is
right after.
