* [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
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) The audit_ipc_perms() function has been split into two different functions: - audit_ipc_obj() - audit_ipc_set_perm() There's a key shift here... 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>

| * [PATCH] support for context based audit filtering, part 2Darrel Goeddel2006-05-014-27/+256
| | | | | | | | | | | | | | | | | | | | | | This patch provides the ability to filter audit messages based on the elements of the process' SELinux context (user, role, type, mls sensitivity, and mls clearance). It uses the new interfaces from selinux to opaquely store information related to the selinux context and to filter based on that information. It also uses the callback mechanism provided by selinux to refresh the information when a new policy is loaded. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | The following patch provides selinux interfaces that will allow the audit system to perform filtering based on the process context (user, role, type, sensitivity, and clearance). These interfaces will allow the selinux module to perform efficient matches based on lower level selinux constructs, rather than relying on context retrievals and string comparisons within the audit module. It also allows for dominance checks on the mls portion of the contexts that are impossible with only string comparisons.

* | [NETFILTER] x_tables: fix compat related crash on non-x86Patrick McHardy2006-05-012-19/+22

On 32 bit architectures where iptables aligns to 8 byte it will also have 4 byte padding at the end because it is only 36 bytes large. The compat_ipt_standard_fn in the kernel adjusts the offsets by sizeof(struct ipt_standard_target) - sizeof(struct compat_ipt_standard_target), which will always result in 4, even if the structure from userspace was already padded to a multiple of 8. On x86 this works out by accident because userspace only aligns to 4, on all other architectures this is broken and causes incorrect adjustments to the size and following offsets.

Splice rarely needs to access the virtual address of a page, so it's a waste of time doing it. Introduce ->pin() to take over the responsibility of making sure the page data is valid. ->map() is then reduced to just kmap().

The reason for that is that the arch code apparently has to explictly add a "pcspkr" platform device in order for the driver core to call the ->probe() routine. arch/i386/kernel/setup.c unconditionally adds a "pcspkr" device, but the x86_64 kernel has no code at all related to the PC Speaker. The patch below copies the relevant code from i386 to x86_64, which makes the PC Speaker work for me on x86_64.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix genrtc's read() routine for 64-bit platforms. Current gen_rtc_read() stores 64bit integer and returns 8 even if an user tried to read a 32bit integer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make rtc-dev work well on 64-bit platforms with 32-bit userland. On those platforms, users might try to read 32-bit integer value. This patch make rtc-dev's read() work well for both "int" and "long" size. This tweak is came from genrtc driver.
