| | * [PATCH] drivers/base/bus.c: fix iteration in driver_detach()Roman Kagan2005-05-041-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With 2.6.11 and 2.6.12-rc2 (and perhaps a few versions before) usb drivers for multi-interface devices, which do usb_driver_release_interface() in their disconnect(), make rmmod hang. It turns out to be due to a bug in drivers/base/bus.c:driver_detach(), that iterates over the list of attached devices with list_for_each_safe() under an assumption that device_release_driver() only releases the current device, while it may also call device_release_driver() for other devices on the same list. The following patch fixes it. Please consider applying. Signed-off-by: Roman Kagan <rkagan@mail.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * | [AUDIT] Log correct syscall args for i386 processes on x86_64David Woodhouse2005-05-031-7/+13

| * | [PATCH] add new audit data to last skbChris Wright2005-05-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When adding more formatted audit data to an skb for delivery to userspace, the kernel will attempt to reuse an skb that has spare room. However, if the audit message has already been fragmented to multiple skb's, the search for spare room in the skb uses the head of the list. This will corrupt the audit message with trailing bytes being placed midway through the stream. Fix is to look at the end of the list.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is for -mm only. It should probably be included in git-audit, and should be forwarded to Linus iff git-audit is. It updates the audit-syscall-{entry,exit} calls to current -mm.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attached is a new patch that solves the issue of getting valid credentials into the LOGIN message. The current code was assuming that the audit context had already been copied. This is not always the case for LOGIN messages. To solve the problem, the patch passes the task struct to the function that emits the message where it can get valid credentials.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attached is a patch against David's audit.17 kernel that adds checks for the TIF_SYSCALL_AUDIT thread flag to the ia64 system call and signal handling code paths.The patch enables auditing of system calls set up via fsys_bubble_down, as well as ensuring that audit_syscall_exit() is called on return from sigreturn. Neglecting to check for TIF_SYSCALL_AUDIT at these points results in incorrect information in audit_context, causing frequent system panics when system call auditing is enabled on an ia64 system.

| * | | [AUDIT] Don't allow ptrace to fool auditing, log arch of audited syscalls.2005-04-298-58/+139

Reorder the calls to fix that. While we're touching ever call to audit_syscall_entry(), we also make it take an extra argument: the architecture of the syscall which was made, because some architectures allow more than one type of syscall. Also add an explicit success/failure flag to audit_syscall_exit(), for the benefit of architectures which return that in a condition register rather than only returning a single register. Change type of syscall return value to 'long' not 'int'. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Main change is in path_lookup: added a goto to do audit_inode instead of return statement, when emul_lookup_dentry for root is successful.The existing code does audit_inode only when lookup is done in normal root or cwd. Other changes: Some lookup routines are returning zero on success, and some are returning zero on failure. I documented the related function signatures in this code path, so that one can glance over abstract functions without understanding the entire code.
