refcnt/bindcnt are only used in user context under the rtnl, no additional locking is necessary. Besides it was only done in some places, so kill it. Signed-off-by:

Simply kill the pskb_expand_head, iptables targets already take care of cloned packets. Signed-off-by:

- Return proper error codes - Some attribute sizes are not checked - rta may by NULL - multiple leaks - possible unbalanced unlock - used action is freed after if an error happens while trying to replace - estimator can't be replaced This patch makes replacement atomic, so the old action is either replaced entirely or not touched at all.

- Return proper error codes - Attribute sizes are not checked - rta may by NULL - The action is inserted into the hash before its parameters are set - replacement happens without locking - no reallocation on replacement for possibly changed numbers of keys Signed-off-by:

Add rtattr_strlcpy to handle unterminated strings. The destination is nulled out entirely to avoid possible leaks when dumping. The return value can be checked for >= size to detect truncated strings. Currently strings equal to the size of the destination are accepted everywhere even if not null-terminated. Sometimes they are silently truncated, sometimes the unterminated string is used. Signed-off-by:

Thomas Graf points out that I broke net/sched/ipt.c when I removed __ipt_find_target_lock. In fact, those routines don't need to keep the lock held, so we can simplify them, and expose an interface (ipt_find_target) which does module loading correctly for net/sched/ipt.c. Signed-off-by:

Transforms tcindex to use tcf_exts API and thus adds support for actions. Needs more work to allow changing parameters for existing filters. Signed-off-by:

Transforms tcindex to use tcf_exts API and thus adds support for actions. Replaces the existing change implementation with a new one supporting changes for existing filters which allows to change a classifier without letting a single packet pass by unclassified. Fixes various cases where a error is returned but the filter was changed already. Signed-off-by:

The tcf_exts API abstracts extensions such as actions/policers into a generic layer and reduces the knowledge inside classifiers to the minimum required. It isolates the validation code into its own function to allow classifiers to validate all input data before making changes and thus avoids the need to undo changes if a extension configuration request cannot be fullfilled. Adds missing locking when adding a action/police extension to an already existing filter. Acquiring dev->queue_lock makes sure we don't change the action/police in the middle of a classification. Noted by Patrick McHardy. As a nice side effect, using this API removes the existing ifdef clutter. Usage: The classifier holds struct tcf_exts which may be empty if no extensions are compiled in. It then calls tcf_exts_validate when a new change request was received and provides a temporary tcf_exts copy to store the change requests. Given it succeeded the classifier may change its own parameters and at the end call tcf_exts_change to commit the changes and replace the existing extension configuration with the new one. The classifier is responsible to destroy his temporary copy if any of its own validation checks fail. The classifier specific TLV types must be exported to the extensions API via tcf_ext_map. Destroying the extensions is as easy as calling tcf_exts_destroy. The extensions are executed by the classifier by calling tcf_exts_exec which must be done as the last thing after making sure the filter matches. Note: A classifier might take further actions after the execution to tcf_exts_exec such as correcting its own cache to avoid caching results which could have been influenced by the extensions. tcf_exts_exec returns a negative error code if the filter must be considered unmatched, 0 on normal execution or a positive classifier return code (TC_ACT_*) which must be returned to the underlying layer as-is.

The 8139too thread needs to use rtnl_lock_interruptible so it can avoid doing the actual work once it's been kill_proc()ed on module removal time. Based on debugging and an earlier patch that adds a driver-private semaphore from Herbert Xu. Signed-off-by: -
