This is a regression introduced by commit fd58156e (IPIP: Use ip-tunneling code.) Similar to GRE tunnel, previously we only check the parameters for SIOCADDTUNNEL and SIOCCHGTUNNEL, after that commit, the check is moved for all commands. So, just check for SIOCADDTUNNEL and SIOCCHGTUNNEL. Also, the check for i_key, o_key etc. is suspicious too, which did not exist before, reset them before passing to ip_tunnel_ioctl().

The TPACKET_V3 test code consists of a lot of unecessary macro wrappers that rather obfuscate what members are accessed in what way. So get rid of them and make the code more readable. Also credit Chetan for providing tpacket_v3 example code. Furthermore, get rid of private offset usage, as we do not need it here. Signed-off-by:

As the patch "bnx2x: remove zeroing of dump data buffer" showed, it is too easy implement .get_dump_data incorrectly in a driver. Let's make sure drivers cannot get confused by userspace requesting a too big dump. Also WARN if the driver sets dump->len to something weird and make sure the length reported to userspace is the actual length of data copied to userspace. Signed-off-by:

bnx2x did not set dump->version in its .get_dump_flag() method. Let's set it to BNX2X_DUMP_VERSION. It's not a particularly nice number (0x50acff01 currently), but at least it's something deterministic. dump->flag should report the value previously set using ethtool -W. Signed-off-by:

bnx2x interprets the dump flag as an index of a register preset. It is important to validate the index to avoid out of bounds memory accesses. Signed-off-by:

Michal Schmidt authored
There is no need to initialize the dump data with zeros. data is allocated with vzalloc, so it's already zero-filled. More importantly, the memset is harmful, because dump->len (the length requested by userspace) can be bigger than the allocated buffer (whose size is determined by asking the driver's .get_dump_flag method).

After having reworked the debugging framework, Neil and Vlad agreed to get rid of the leftover SCTP_DBG_TSNS code for a couple of reasons: We can use systemtap scripts to investigate these things, we now have pr_debug() helpers that make life easier, and if we really need anything else besides those tools, we will be forced to come up with something better than we have there. Therefore, get rid of this ifdef debugging code entirely for now. Signed-off-by:

We should get rid of all own SCTP debug printk macros and use the ones that the kernel offers anyway instead. This makes the code more readable and conform to the kernel code, and offers all the features of dynamic debbuging that pr_debug() et al has, such as only turning on/off portions of debug messages at runtime through debugfs. The runtime cost of having CONFIG_DYNAMIC_DEBUG enabled, but none of the debug statements printing, is negligible [1]. If kernel debugging is completly turned off, then these statements will also compile into "empty" functions. While we're at it, we also need to change the Kconfig option as it /now/ only refers to the ifdef'ed code portions in outqueue.c that enable further debugging/tracing of SCTP transaction fields. Also, since SCTP_ASSERT code was enabled with this Kconfig option and has now been removed, we transform those code parts into WARNs resp. where appropriate BUG_ONs so that those bugs can be more easily detected as probably not many people have SCTP debugging permanently turned on. To turn on all SCTP debugging, the following steps are needed: # mount -t debugfs none /sys/kernel/debug # echo -n 'module sctp +p' > /sys/kernel/debug/dynamic_debug/control This can be done more fine-grained on a per file, per line basis and others as described in [2].

In order to avoid making code that deals with printing both, IPv4 and IPv6 addresses, unnecessary complicated as for example ... if (sa.sa_family == AF_INET6) printk("... %pI6 ...", ..sin6_addr); else printk("... %pI4 ...", ..sin_addr.s_addr); ... it would be better to introduce a format specifier that can deal with those kind of situations internally; just as we have a "struct sockaddr" for generic mapping into "struct sockaddr_in" or "struct sockaddr_in6" as e.g. done in "union sctp_addr". Then, we could reduce the above statement into something like: printk("... %pIS ..", &sockaddr); In case our pointer is NULL, pointer() then deals with that already at an earlier point in time internally. While we're at it, support for both %piS/%pIS, where 'S' stands for sockaddr, comes (almost) for free. Additionally to that, postfix specifiers 'p', 'f' and 's' are supported as suggested and initially implemented in 2009 by Joe Perches [1]. Handling of those additional specifiers orientate on the initial RFC that was proposed. Also we support IPv6 compressed format specified by 'c' and various other IPv4 extensions as stated in the documentation part. Likely, there are many other areas than just SCTP in the kernel to make use of this extension as well. [1] http://patchwork.ozlabs.org/patch/31480/Signed-off-by: -

Bjørn Mork authored
The MC8305 module got an additional entry added based solely on information from a Windows driver *.inf file. We now have the actual descriptor layout from one of these modules, and it consists of two alternate configurations where cfg #1 is a normal Gobi 2k layout and cfg #2 is MBIM only, using interface numbers 5 and 6 for MBIM control and data. The extra Windows driver entry for interface number 5 was most likely a bug. Deleting the bogus entry to avoid unnecessary qmi_wwan probe failures when using the MBIM configuration. Reported-by:

John W. Linville says: ==================== Yet one more pull request for wireless updates intended for 3.11... For the mac80211 bits, Johannes says: "Here we have a few memory leak fixes related to BSS struct handling mostly from Ben, including a fix for a more theoretical problem (associating while a BSS struct times out) from myself, a compilation warning fix from Arend, mesh fixes from Thomas, tracking the beacon bitrate (Alex), a bandwidth change event fix (Ilan) and some initial work for 5/10 MHz channels from Simon." Regarding the iwlwifi bits, Johannes says: "Emmanuel removed some unneeded/unsupported module parameters and adds a Bluetooth 1x1 lookup-table for some upcoming products. From Alex I have an older patch to add low-power receive support, this depended on a mac80211 commit that only just came in with the merge from wireless-next I did. Ilan made beacon timings better, and Eytan added some debug statements for thermal throttling. I have a few cleanups, a fix for a long-standing but rare warning, and, arguably the most important patch here, the firmware API version bump for the 7260/3160 devices." Also included is a Bluetooth pull -- Gustavo says: "Here goes a set of patches to 3.11. The biggest work here is from Andre Guedes on the move of the Discovery to use the new request framework. Other than that Johan provided a bunch of fixes to the L2CAP code. The rest are just small fixes and clean ups." On top of all that, there are a variety of updates and fixes to brcmfmac, rt2x00, wil6210, ath9k, ath10k, and a few others here and there. This also includes a pull of the wireless tree, in order to prevent some merge conflicts. ==================== Signed-off-by: -
