2007-10-23[IPV4]: Explicitly call fib_get_table() in fib_frontend.cPavel Emelyanov
In case the "multiple tables" config option is y, the ip_fib_local_table is not a variable, but a macro, that calls fib_get_table(RT_TABLE_LOCAL). Some code uses this "variable" *3* times in one place, thus implicitly making 3 calls. Fix it. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-10-23[NET]: Remove in-code externs for some functions from net/core/dev.cPavel Emelyanov

Commits 58b053e4ce9d2fc3023645c1b96e537c72aa8d9a ("Update arch/ to use sg helpers") 45711f1af6eff1a6d010703b4862e0d2b9afd056 ("[SG] Update drivers to use sg helpers") fa05f1286be25a8ce915c5dd492aea61126b3f33 ("Update net/ to use sg helpers") converted many files to use the scatter gather helpers without ensuring that the necessary headerfile <linux/scatterlist> is included. This happened to work for ia64, powerpc, sparc64 and x86 because they happened to drag in that file via their <asm/dma-mapping.h>. On most of the others this probably broke.

2007-10-22[Bluetooth] Switch from OGF+OCF to using only opcodesMarcel Holtmann
The Bluetooth HCI commands are divided into logical OGF groups for easier identification of their purposes. While this still makes sense for the written specification, its makes the code only more complex and harder to read. So instead of using separate OGF and OCF values to identify the commands, use a common 16-bit opcode that combines both values. As a side effect this also reduces the complexity of OGF and OCF calculations during command header parsing. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2007-10-19pid namespaces: changes to show virtual ids to userPavel Emelyanov
This is the largest patch in the set. Make all (I hope) the places where the pid is shown to or get from user operate on the virtual pids. The idea is: - all in-kernel data structures must store either struct pid itself or the pid's global nr, obtained with pid_nr() call; - when seeking the task from kernel code with the stored id one should use find_task_by_pid() call that works with global pids; - when showing pid's numerical value to the user the virtual one should be used, but however when one shows task's pid outside this task's namespace the global one is to be used; - when getting the pid from userspace one need to consider this as the virtual one and use appropriate task/pid-searching functions.

2007-10-19Make access to task's nsproxy lighterPavel Emelyanov
When someone wants to deal with some other taks's namespaces it has to lock the task and then to get the desired namespace if the one exists. This is slow on read-only paths and may be impossible in some cases. E.g. Oleg recently noticed a race between unshare() and the (sent for review in cgroups) pid namespaces - when the task notifies the parent it has to know the parent's namespace, but taking the task_lock() is impossible there - the code is under write locked tasklist lock. On the other hand switching the namespace on task (daemonize) and releasing the namespace (after the last task exit) is rather rare operation and we can sacrifice its speed to solve the issues above. The access to other task namespaces is proposed to be performed like this: rcu_read_lock(); nsproxy = task_nsproxy(tsk); if (nsproxy != NULL) { / * * work with the namespaces here * e.g. get the reference on one of them * / } / * * NULL task_nsproxy() means that this task is * almost dead (zombie) * / rcu_read_unlock(); This patch has passed the review by Eric and Oleg :) and, of course, tested.

2007-10-18[NET]: Fix possible dev_deactivate race conditionHerbert Xu
The function dev_deactivate is supposed to only return when all outstanding transmissions have completed. Unfortunately it is possible for store operations in the driver's transmit function to only become visible after dev_deactivate returns. This patch fixes this by taking the queue lock after we see the end of the queue run. This ensures that all effects of any previous transmit calls are visible. If however we detect that there is another queue run occuring, then we'll warn about it because this should never happen as we have pointed dev->qdisc to noop_qdisc within the same queue lock earlier in the functino.
