2013-02-04netns: fdb: allow unprivileged users to add/del fdb entriesGao feng1-6/+0
Right now,only ixgdb,macvlan,vxlan and bridge implement fdb_add/fdb_del operations. these operations only operate the private data of net device. So allowing the unprivileged users who creates the userns and netns to add/del fdb entries will do no harm to other netns. Signed-off-by: Gao feng <gaofeng@cn.fujitsu.com> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Paul Gortmaker says: ==================== The removal of wanrouter code was originally listed in the (now gone) feature removal file since May 2012, and an RFC of the deletion was posted[1] in late 2012. The overall concept was given an OK, but defconfig contamination, build failures, etc. meant that it didn't quite make it into mainline for 3.8. Since that time, Dan discovered (via code audit) a runtime bug that proves nobody has been using this for over four years[2]. With that new information, I think it makes sense for someone to follow through on Joe's original RFC and get this done for the 3.9 release. In addition to resolving the build failures of the RFC by keeping stub headers, this also splits the change into two parts, just like the token ring removal did. Part #1 decouples the mainline kernel from the expired subsystem, and part #2 does the large scale deletion of the subsystem content. The advantage of the above, is that a "git blame" will never lead you to a 4000+ line deletion commit. The large scale deletion will never show up in a "git blame" and hence the same advantages that we get from the "--irreversible-delete" in the review stage of "git format-patch" are also embedded into the git history itself. This may seem like a moot point to some, but for those who spend a considerable amount of time data mining in the git history, this is probably worth doing. I have done build tests of all[mod/yes]config for both the stage 1 (Makefile and Kconfig) and stage 2 (full driver delete) as a sanity check, and the issues with the previously posted RFC should be gone. Speaking of "--irreversible-delete" -- these patches were created with that option, so if you want to use them locally, you are going to have to pull (location below) the content instead of doing a "git am" of the mailed out content.

Jeff Kirsher says: ==================== This series contains updates to ixgbe and e1000e. The ixgbe patches are a mix of fixes, cleanup and added functionality. The first fix is for traffic classes, where if the mapping has changed reset the NIC. The other ixgbe fix resolves an issue where the device lookup neglected to do a pci_dev_put() to decrement the device reference count. The ixgbe cleanup was done by Josh, where the auto-negotiation variables were renamed/cleaned up and refactored. The remaining patches are from Bruce to do additional cleanup on e1000e as well as bump the driver version. Most notably is the cleanup to use the kernel IEEE MII definitions where possible instead of the local MII definitions. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Do not replace references of MII_CR_SPEED_10 with BMCR_SPEED10 (0x0000) when it is not necessary (i.e. when it is bitwise OR'ed with another value).

2013-01-31wanrouter: delete now orphaned header content, files/driversPaul Gortmaker12-4417/+8
The wanrouter support was identified earlier as unused for years, and so the previous commit totally decoupled it from the kernel, leaving the related wanrouter files present, but totally inert. Here we take the final step in that cleanup, by doing a wholesale removal of these files. The two step process is used so that the large deletion is decoupled from the git history of files that we still care about. The drivers deleted here all were dependent on the Kconfig setting CONFIG_WAN_ROUTER_DRIVERS. A stub wanrouter.h header (kernel & uapi) are left behind so that drivers/isdn/i4l/isdn_x25iface.c continues to compile, and so that we don't accidentally break userspace that expected these defines.

2013-01-31wanrouter: completely decouple obsolete code from kernel.Paul Gortmaker9-66/+3
The original suggestion to delete wanrouter started earlier with the mainline commit f0d1b3c2bcc5de8a17af5f2274f7fcde8292b5fc ("net/wanrouter: Deprecate and schedule for removal") in May 2012. More importantly, Dan Carpenter found[1] that the driver had a fundamental breakage introduced back in 2008, with commit 7be6065b39c3 ("netdevice wanrouter: Convert directly reference of netdev->priv"). So we know with certainty that the code hasn't been used by anyone willing to at least take the effort to send an e-mail report of breakage for at least 4 years. This commit does a decouple of the wanrouter subsystem, by going after the Makefile/Kconfig and similar files, so that these mainline files that we are keeping do not have the big wanrouter file/driver deletion commit tied into their history. Once this commit is in place, we then can remove the obsolete cyclomx drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.
