* [MTD] Fix legacy character sets throughout drivers/mtd, include/linux/mtdDavid Woodhouse2006-05-1411-17/+17

* [MTD] Deal correctly with NOR chips which are smaller than the map windowDavid Woodhouse2006-05-141-2/+14
| | | | | | | | | | | | We used to calculate the number of chips to be zero, allocate an array of that size, then nasty things would happen when we attempt to access the first object in that zero-sized array. Now, if the number of _full_ chips that would fit into the map is zero, we allocate an array of one anyway, and then artificially reduce the total size of the resulting MTD device to fit in the map.

* mtd: fix memory leak in block2mtd_setup()Jesper Juhl2006-05-141-3/+6
| | | | | | | | | | | | | There's a mem leak in drivers/mtd/devices/block2mtd.c::block2mtd_setup() We can leak 'name' allocated with kmalloc in 'parse_name' if leave via the 'parse_err' macro since it contains a return but doesn't do any freeing.

* [MTD] Fix module refcounting in NAND board drivers.David Woodhouse2006-05-1414-4/+27
| | | | | | | | | The _board_ driver needs to be mtd->owner, and it in turn pins the nand.ko module. Fix them all to actually do that, and fix nand.ko not to overwrite it -- and also to check that the caller sets it, if the caller is a module. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* mtd: fix memory leaks in phram_setupJesper Juhl2006-05-141-2/+6
| | | | | | | | | | | | | | There are two code paths in drivers/mtd/devices/phram.c::phram_setup() that will leak memory. Memory is allocated to the variable 'name' with kmalloc() by the parse_name() function, but if we leave by way of the parse_err() macro, then that memory is never kfree()'d, nor is it ever used with register_device() so it won't be freed later either - leak. Found by the Coverity checker as #593 - simple fix below. Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

* [MTD] Convert physmap to platform driverLennert Buytenhek2006-05-073-83/+196
| | | | | | | | | | | | | | | | | | | | | | | | | | | After dwmw2 let me know it ought to be done, I rewrote the physmap map driver to be a platform driver. I know zilch about the driver model, so I probably botched it in some way, but I've done some tests on an ixp23xx board which uses physmap, and it all seems to work. In order to not break existing physmap users, I've added some compat code that will instantiate a platform device iff CONFIG_MTD_PHYSMAP_LEN is defined and != 0. Also, I've changed the default value for CONFIG_MTD_PHYSMAP_LEN to zero, so that people who inadvertently compile in physmap (or new, platform-style, users of physmap) don't get burned. This works pretty well -- the new physmap driver is a drop-in replacement for the old one, and works on said ixp23xx board without any code changes needed. (This should hold as long as users don't touch 'physmap_map' directly.) Once all physmap users have been converted to instantiate their own platform devices, the compat code can go. (Or we decide that we can change all the in-tree users at the same time, and never merge the compat code.)

| * [PATCH] via-rhine: zero pad short packets on Rhine I ethernet cardsCraig Brind2006-05-021-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes Rhine I cards disclosing fragments of previously transmitted frames in new transmissions. Before transmission, any socket buffer (skb) shorter than the ethernet minimum length of 60 bytes was zero-padded. On Rhine I cards the data can later be copied into an aligned transmission buffer without copying this padding. This resulted in the transmission of the frame with the extra bytes beyond the provided content leaking the previous contents of this buffer on to the network. Now zero-padding is repeated in the local aligned buffer if one is used. Following a suggestion from the via-rhine maintainer, no attempt is made here to avoid the duplicated effort of padding the skb if it is known that an aligned buffer will definitely be used. This is to make the change "obviously correct" and allow it to be applied to a stable kernel if necessary. There is no change to the flow of control and the changes are only to the Rhine I code path. The patch has run on an in-service Rhine-I host without incident. Frames shorter than 60 bytes are now correctly zero-padded when captured on a separate host. I see no unusual stats reported by ifconfig, and no unusual log messages.

| | * [PATCH] Rework of IPC auditingSteve Grubb2006-05-016-11/+98

The audit_ipc_obj() collects the uid, gid, mode, and SElinux context label of the current ipc object. This audit_ipc_obj() hook is now found in several places. Most notably, it is hooked in ipcperms(), which is called in various places around the ipc code permforming a MAC check. Additionally there are several places where *checkid() is used to validate that an operation is being performed on a valid object while not necessarily having a nearby ipcperms() call. In these locations, audit_ipc_obj() is called to ensure that the information is captured by the audit system. The audit_set_new_perm() function is called any time the permissions on the ipc object changes. In this case, the NEW permissions are recorded (and note that an audit_ipc_obj() call exists just a few lines before each instance). 2) Support for an AUDIT_IPC_SET_PERM audit message type. This allows for separate auxiliary audit records for normal operations on an IPC object and permissions changes. Note that the same struct audit_aux_data_ipcctl is used and populated, however there are separate audit_log_format statements based on the type of the message. Finally, the AUDIT_IPC block of code in audit_free_aux() was extended to handle aux messages of this new type. No more mem leaks I hope ;-) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
