When I added the new style module aliases to the filesystems I deleted the old ones. A bad move. It turns out that distributions like Arch linux use module aliases when constructing ramdisks. Which meant ultimately that an ext3 filesystem mounted with ext4 would not result in the ext4 module being put into the ramdisk. The other change in this tree adds a handful of filesystem module alias I simply failed to add the first time. Which inconvinienced a few folks using cifs. I don't want to inconvinience folks any longer than I have to so here are these trivial fixes." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: fs: Readd the fs module aliases. fs: Limit sys_mount to only request filesystem modules.

| * fs: Readd the fs module aliases.Eric W. Biederman2013-03-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I had assumed that the only use of module aliases for filesystems prior to "fs: Limit sys_mount to only request filesystem modules." was in request_module. It turns out I was wrong. At least mkinitcpio in Arch linux uses these aliases. So readd the preexising aliases, to keep from breaking userspace. Userspace eventually will have to follow and use the same aliases the kernel does. So at some point we may be delete these aliases without problems. However that day is not today.

The problem is that mounts are usually done with some host principal which isn't normally mapped to any user, in which case svcgssd passes down uid -1, which the kernel is then expected to map to the export-specific anonymous uid or gid. The new uid_valid/gid_valid checks were therefore causing that downcall to fail. (Note the regression may not have been seen with older userspace that tended to map unknown principals to an anonymous id on their own rather than leaving it to the kernel.) Reviewed-by: "Eric W.

For new userspace and kernel 3.10 we're going to implement a new "split dump" protocol that can use multiple messages per wiphy. For now though, add a workaround to be able to send more information to userspace. Since generic netlink doesn't have a way to set the minimum dump size globally, and we wouldn't really want to set it globally anyway, increase the size only when needed, as described in the comments. As userspace might not be prepared for large buffers, we can only use 4k. Also increase the size for the get_wiphy command. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

However, if the addresses of the routers are prespecified in the option, then the overflow condition cannot happen: the option is structured so that each prespecified router has a place to write its timestamp. Other routers do not add a timestamp, so there will never be a lack of space. This fix ensures that the Overflow value in the IPv4 timestamp option is not incremented when the addresses of the routers are prespecified, even if the Pointer value is greater than the Length value.

As a consequence, for QFQ+ to be work conserving, at least one of the active aggregates must be eligible when it is time to choose the next aggregate to serve. The set of eligible aggregates is updated through the function qfq_update_eligible(), which does guarantee that, after its invocation, at least one of the active aggregates is eligible. Because of this property, this function is invoked in qfq_deactivate_agg() to guarantee that at least one of the active aggregates is still eligible after an aggregate has been deactivated. In particular, the critical case is when there are other active aggregates, but the aggregate being deactivated happens to be the only one eligible. However, this precaution is not needed for QFQ+ to be work conserving, because update_eligible() is always invoked also at the beginning of qfq_choose_next_agg(). This patch removes the additional invocation of update_eligible() in qfq_deactivate_agg().

For this reason, after a new aggregate has been selected for service, its next packet is immediately dequeued, without any further control. The maximum packet size for a class, lmax, can be changed through qfq_change_class(). In case the user sets lmax to a lower value than the the size of some of the still-to-arrive packets, QFQ+ will automatically push up lmax as it enqueues these packets. This automatic push up is likely to happen with TSO/GSO. In any case, if lmax is assigned a lower value than the size of some of the packets already enqueued for the class, then the following problem may occur: the size of the next packet to dequeue for the class may happen to be larger than lmax, after the aggregate to which the class belongs has been just selected for service. In this case, even the budget of the aggregate, which is an unsigned value, may be lower than the size of the next packet to dequeue. After dequeueing this packet and subtracting its size from the budget, the latter would wrap around. This fix prevents the budget from wrapping around after any packet dequeue.

For this reason, to guarantee QFQ+ to be work conserving, a just-activated aggregate must be set as in service immediately if it happens to be the only active aggregate. This is done by the function qfq_enqueue(). Unfortunately, the function qfq_add_to_agg(), used to add a class to an aggregate, does not perform this important additional operation. In particular, if: 1) qfq_add_to_agg() is invoked to complete the move of a class from a source aggregate, becoming, for this move, inactive, to a destination aggregate, becoming instead active, and 2) the destination aggregate becomes the only active aggregate, then this aggregate is not however set as in service. QFQ+ remains then in a non-work-conserving state until a new invocation of qfq_enqueue() recovers the situation. This fix solves the problem by moving the logic for setting an aggregate as in service directly into the function qfq_activate_agg(). Hence, from whatever point qfq_activate_aggregate() is invoked, QFQ+ remains work conserving. Since the more-complex logic of this new version of activate_aggregate() is not necessary, in qfq_dequeue(), to reschedule an aggregate that finishes its budget, then the aggregate is now rescheduled by invoking directly the functions needed.

The bucket in which each aggregate is inserted depends on the aggregate's timestamps, and the number of buckets in a group is enough to accomodate the possible (range of) values of the timestamps of all the aggregates in the group. For this property to hold, timestamps must however be computed correctly. One necessary condition for computing timestamps correctly is that the number of bits dequeued for each aggregate, while the aggregate is in service, does not exceed the maximum budget budgetmax assigned to the aggregate. For each aggregate, budgetmax is proportional to the number of classes in the aggregate. If the number of classes of the aggregate is decreased through qfq_change_class(), then budgetmax is decreased automatically as well. Problems may occur if the aggregate is in service when budgetmax is decreased, because the current remaining budget of the aggregate and/or the service already received by the aggregate may happen to be larger than the new value of budgetmax. In this case, when the aggregate is eventually deselected and its timestamps are updated, the aggregate may happen to have received an amount of service larger than budgetmax. This may cause the aggregate to be assigned a higher virtual finish time than the maximum acceptable value for the last bucket in the bucket list of the group. This fix introduces a cap that addresses this issue. Signed-off-by: Paolo Valente <paolo.valente@unimore.it> Reviewed-by: Fabio Checconi <fchecconi@gmail.com> Signed-off-by: David S.

A common practice is to build all of the kernel code and leave code that is not commonly needed as modules, with the result that many users are exposed to any bug anywhere in the kernel. Looking for filesystems with a fs- prefix limits the pool of possible modules that can be loaded by mount to just filesystems trivially making things safer with no real cost. Using aliases means user space can control the policy of which filesystem modules are auto-loaded by editing /etc/modprobe.d/*.conf with blacklist and alias directives. Allowing simple, safe, well understood work-arounds to known problematic software. This also addresses a rare but unfortunate problem where the filesystem name is not the same as it's module name and module auto-loading would not work. While writing this patch I saw a handful of such cases. The most significant being autofs that lives in the module autofs4. This is relevant to user namespaces because we can reach the request module in get_fs_type() without having any special permissions, and people get uncomfortable when a user specified string (in this case the filesystem type) goes all of the way to request_module. After having looked at this issue I don't think there is any particular reason to perform any filtering or permission checks beyond making it clear in the module request that we want a filesystem module. The common pattern in the kernel is to call request_module() without regards to the users permissions. In general all a filesystem module does once loaded is call register_filesystem() and go to sleep. Which means there is not much attack surface exposed by loading a filesytem module unless the filesystem is mounted. In a user namespace filesystems are not mounted unless .fs_flags = FS_USERNS_MOUNT, which most filesystems do not set today.

From Dan Carpenter. 15) Add AISX AX88179 USB driver, from Freddy Xin. 16) Remove MAINTAINERS entries for drivers deleted during the merge window, from Cesar Eduardo Barros. 17) RDS protocol can try to allocate huge amounts of memory, check that the user's request length makes sense, from Cong Wang. 18) SCTP should use the provided KMALLOC_MAX_SIZE instead of it's own, bogus, definition. From Cong Wang. 19) Fix deadlocks in FEC driver by moving TX reclaim into NAPI poll, from Frank Li. Also, fix a build error introduced in the merge window. 20) Fix bogus purging of default routes in ipv6, from Lorenzo Colitti. 21) Don't double count RTT measurements when we leave the TCP receive fast path, from Neal Cardwell." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (61 commits) tcp: fix double-counted receiver RTT when leaving receiver fast path CAIF: fix sparse warning for caif_usb rds: simplify a warning message net: fec: fix build error in no MXC platform net: ipv6: Don't purge default router if accept_ra=2 net: fec: put tx to napi poll function to fix dead lock sctp: use KMALLOC_MAX_SIZE instead of its own MAX_KMALLOC_SIZE rds: limit the size allocated by rds_message_alloc() MAINTAINERS: remove eexpress MAINTAINERS: remove drivers/net/wan/cycx* MAINTAINERS: remove 3c505 caif_dev: fix sparse warnings for caif_flow_cb ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driver sctp: use the passed in gfp flags instead GFP_KERNEL ipv[4|6]: correct dropwatch false positive in local_deliver_finish l2tp: Restore socket refcount when sendmsg succeeds net/phy: micrel: Disable asymmetric pause for KSZ9021 bgmac: omit the fcs phy: Fix phy_device_free memory leak bnx2x: Fix KR2 work-around condition ...
