commit f9a7ba32 upstream. An earlier bug fix of mine made the SND_DM365_VOICE_CODEC symbol tristate to avoid creating an undefined reference from the davinci-vcif.c driver to the davinci_soc_platform_register function that may be in a module. However, this may now lead to a different error on randconfig kernels: "warning: SND_DM365_VOICE_CODEC creates inconsistent choice state" This happens because we now have a choice statement with one bool and one tristate option, and the latter might not support being set to 'y' because of dependencies. This new change turns the other option into 'tristate' as well, which avoids the problem. Signed-off-by:

commit 7331ea47 upstream. Commit f6b2a045 ("ASoC: pxa: mioa701_wm9713: Convert to table based DAPM setup") converted the driver to register the board level DAPM elements with the card's DAPM context rather than the CODEC's DAPM context. The change overlooked that the speaker widget event callback accesses the widget's codec field which is only valid if the widget has been registered in a CODEC DAPM context. This patch modifies the callback to take an alternative route to get the CODEC. Fixes: f6b2a045 ("ASoC: pxa: mioa701_wm9713: Convert to table based DAPM setup") Signed-off-by:

commit 16b036af upstream. If the image size would ever read as 0, pci_get_rom_size() could keep processing the same image over and over again. Exit the loop if we ever read a length of zero. This fixes a soft lockup on boot when the radeon driver calls pci_get_rom_size() on an AMD Radeon R7 250X PCIe discrete graphics card.

commit 145b3fe5 upstream. Some implementations of modprobe fail to load the driver for a PCI device automatically because the "interface" part of the modalias from the kernel is lowercase, and the modalias from file2alias is uppercase. The "interface" is the low-order byte of the Class Code, defined in PCI r3.0, Appendix D. Most interface types defined in the spec do not use alpha characters, so they won't be affected. For example, 00h, 01h, 10h, 20h, etc. are unaffected. Print the "interface" byte of the Class Code in uppercase hex, as we already do for the Vendor ID, Device ID, Class, etc. Commit 89ec3dcf ("PCI: Generate uppercase hex for modalias interface class") fixed only half of the problem. Some udev implementations rely on the uevent file and not the modalias file.

commit 6d00f37e upstream. d1c7e29e (HID: i2c-hid: prevent buffer overflow in early IRQ) changed hid_get_input() to read ihid->bufsize bytes, which can be more than wMaxInputLength. This is the case with the Dell XPS 13 9343, and it is causing events to be missed. In some cases the missed events are releases, which can cause the cursor to jump or freeze, among other problems. Limit the number of bytes read to min(wMaxInputLength, ihid->bufsize) to prevent such problems. Fixes: d1c7e29e "HID: i2c-hid: prevent buffer overflow in early IRQ" Signed-off-by:

commit 5523d11c upstream. We don't really need to use different mac colors when adding mac contexts, because they're not used anywhere. In fact, the firmware doesn't accept 255 as a valid color, so we get into a SYSASSERT 0x3401 when we reach that. Remove the color increment to use always zero and avoid reaching 255. Signed-off-by:

commit cd8f4384 upstream. The base address of the scheduler in the device's memory (SRAM) comes from two different sources. The periphery register and the alive notification from the firmware. We have a check in iwl_pcie_tx_start that ensures that they are the same. When we resume from WoWLAN, the firmware may have crashed for whatever reason. In that case, the whole device may be reset which means that the periphery register will hold a meaningless value. When we come to compare trans_pcie->scd_base_addr (which really holds the value we had when we loaded the WoWLAN firmware upon suspend) and the current value of the register, we don't see a match unsurprisingly. Trick the check to avoid a loud yet harmless WARN. Note that when the WoWLAN has crashed, we will see that in iwl_trans_pcie_d3_resume which will let the op_mode know. Once the op_mode is informed that the WowLAN firmware has crashed, it can't do much besides resetting the whole device. Reviewed-by:

commit 6ee8e25f upstream. Commit e9fd702a ("audit: convert audit watches to use fsnotify instead of inotify") broke handling of renames in audit. Audit code wants to update inode number of an inode corresponding to watched name in a directory. When something gets renamed into a directory to a watched name, inotify previously passed moved inode to audit code however new fsnotify code passes directory inode where the change happened. That confuses audit and it starts watching parent directory instead of a file in a directory. This can be observed for example by doing: cd /tmp touch foo bar auditctl -w /tmp/foo touch foo mv bar foo touch foo In audit log we see events like: type=CONFIG_CHANGE msg=audit(1423563584.155:90): auid=1000 ses=2 op="updated rules" path="/tmp/foo" key=(null) list=4 res=1 ... type=PATH msg=audit(1423563584.155:91): item=2 name="bar" inode=1046884 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=DELETE type=PATH msg=audit(1423563584.155:91): item=3 name="foo" inode=1046842 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=DELETE type=PATH msg=audit(1423563584.155:91): item=4 name="foo" inode=1046884 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=CREATE ... and that's it - we see event for the first touch after creating the audit rule, we see events for rename but we don't see any event for the last touch. However we start seeing events for unrelated stuff happening in /tmp. Fix the problem by passing moved inode as data in the FS_MOVED_FROM and FS_MOVED_TO events instead of the directory where the change happens. This doesn't introduce any new problems because noone besides audit_watch.c cares about the passed value: fs/notify/fanotify/fanotify.c cares only about FSNOTIFY_EVENT_PATH events. fs/notify/dnotify/dnotify.c doesn't care about passed 'data' value at all. fs/notify/inotify/inotify_fsnotify.c uses 'data' only for FSNOTIFY_EVENT_PATH. kernel/audit_tree.c doesn't care about passed 'data' at all. kernel/audit_watch.c expects moved inode as 'data'.

commit 3443a3bc upstream. When the superblock is modified in a transaction, the commonly modified fields are not actually copied to the superblock buffer to avoid the buffer lock becoming a serialisation point. However, there are some other operations that modify the superblock fields within the transaction that don't directly log to the superblock but rely on the changes to be applied during the transaction commit (to minimise the buffer lock hold time). When we do this, we fail to mark the buffer log item as being a superblock buffer and that can lead to the buffer not being marked with the corect type in the log and hence causing recovery issues. Fix it by setting the type correctly, similar to xfs_mod_sb()... Tested-by:

commit 0d612fb5 upstream. Jan Kara reported that log recovery was finding buffers with invalid types in them. This should not happen, and indicates a bug in the logging of buffers. To catch this, add asserts to the buffer formatting code to ensure that the buffer type is in range when the transaction is committed. We don't set a type on buffers being marked stale - they are not going to get replayed, the format item exists only for recovery to be able to prevent replay of the buffer, so the type does not matter. Hence that needs special casing here. Reported-by:

commit 19acc77a upstream. There was a bad typo in commit 43759d4f ("random: use an improved fast_mix() function") and I didn't notice because it "looked right", so I saw what I expected to see when I reviewed it. Only months later did I look and notice it's not the Threefish-inspired mix function that I had designed and optimized. Mea Culpa. Each input bit still has a chance to affect each output bit, and the fast pool is spilled *long* before it fills, so it's not a total disaster, but it's definitely not the intended great improvement. I'm still working on finding better rotation constants. These are good enough, but since it's unrolled twice, it's possible to get better mixing for free by using eight different constants rather than repeating the same four. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1400215 ath3k devices fail to load firmwares on xHCI buses, but work well on EHCI, this might be a compatibility issue between xHCI and ath3k chips. As my testing result, those chips will work on xHCI buses again with this patch. This workaround is from Qualcomm, they also did some workarounds in Windows driver. Signed-off-by:

commit a8f29e89 upstream. Userspace expects to see a long space before the first pulse is sent on the lirc device. Currently, if a long time has passed and a new packet is started, the lirc codec just returns and doesn't send anything. This makes lircd ignore many perfectly valid signals unless they are sent in quick sucession. When a reset event is delivered, we cannot know anything about the duration of the space. But it should be safe to assume it has been a long time and we just set the duration to maximum. Signed-off-by:

commit 2d5b86e0 upstream. As of v3.18, ext4 started rejecting a remount which changes the journal_checksum option. Prior to that, it was simply ignored; the problem here is that if someone has this in their fstab for the root fs, now the box fails to boot properly, because remount of root with the new options will fail, and the box proceeds with a readonly root. I think it is a little nicer behavior to accept the option, but warn that it's being ignored, rather than failing the mount, but that might be a subjective matter... Reported-by:

[ Upstream commit cfbf654e ] When making use of RFC5061, section 4.2.4. for setting the primary IP address, we're passing a wrong parameter header to param_type2af(), resulting always in NULL being returned. At this point, param.p points to a sctp_addip_param struct, containing a sctp_paramhdr (type = 0xc004, length = var), and crr_id as a correlation id. Followed by that, as also presented in RFC5061 section 4.2.4., comes the actual sctp_addr_param, which also contains a sctp_paramhdr, but this time with the correct type SCTP_PARAM_IPV{4,6}_ADDRESS that param_type2af() can make use of. Since we already hold a pointer to addr_param from previous line, just reuse it for param_type2af().

[ Upstream commit bdbbb852 ] In commit be9f4a44 ("ipv4: tcp: remove per net tcp_sock") I tried to address contention on a socket lock, but the solution I chose was horrible : commit 3a7c384f ("ipv4: tcp: unicast_sock should not land outside of TCP stack") addressed a selinux regression. commit 0980e56e ("ipv4: tcp: set unicast_sock uc_ttl to -1") took care of another regression. commit b5ec8eea ("ipv4: fix ip_send_skb()") fixed another regression. commit 811230cd ("tcp: ipv4: initialize unicast_sock sk_pacing_rate") was another shot in the dark. Really, just use a proper socket per cpu, and remove the skb_orphan() call, to re-enable flow control. This solves a serious problem with FQ packet scheduler when used in hostile environments, as we do not want to allocate a flow structure for every RST packet sent in response to a spoofed packet.

Alternately, the skb->len check can be moved inside rtnl_notify. For the bridge vlan case described in 92081, there is also a fix needed in bridge driver to generate a proper notification.

[ Upstream commit df4d9254 ] Not caching dst_entries which cause redirects could be exploited by hosts on the same subnet, causing a severe DoS attack. This effect aggravated since commit f8864972 ("ipv4: fix dst race in sk_dst_get()"). Lookups causing redirects will be allocated with DST_NOCACHE set which will force dst_release to free them via RCU. Unfortunately waiting for RCU grace period just takes too long, we can end up with >1M dst_entries waiting to be released and the system will run OOM. rcuos threads cannot catch up under high softirq load. Attaching the flag to emit a redirect later on to the specific skb allows us to cache those dst_entries thus reducing the pressure on allocation and deallocation.

Reference counting of auth keys revisited: Shared keys for AUTH chunks are being stored in endpoints and associations in endpoint_shared_keys list. On endpoint creation, a null key is being added; on association creation, all endpoint shared keys are being cached and thus cloned over to the association. struct sctp_shared_key only holds a pointer to the actual key bytes, that is, struct sctp_auth_bytes which keeps track of users internally through refcounting. Naturally, on assoc or enpoint destruction, sctp_shared_key are being destroyed directly and the reference on sctp_auth_bytes dropped. User space can add keys to either list via setsockopt(2) through struct sctp_authkey and by passing that to sctp_auth_set_key() which replaces or adds a new auth key. There, sctp_auth_create_key() creates a new sctp_auth_bytes with refcount 1 and in case of replacement drops the reference on the old sctp_auth_bytes. A key can be set active from user space through setsockopt() on the id via sctp_auth_set_active_key(), which iterates through either endpoint_shared_keys and in case of an assoc, invokes (one of various places) sctp_auth_asoc_init_active_key(). sctp_auth_asoc_init_active_key() computes the actual secret from local's and peer's random, hmac and shared key parameters and returns a new key directly as sctp_auth_bytes, that is asoc->asoc_shared_key, plus drops the reference if there was a previous one. The secret, which where we eventually double drop the ref comes from sctp_auth_asoc_set_secret() with intitial refcount of 1, which also stays unchanged eventually in sctp_assoc_update(). This key is later being used for crypto layer to set the key for the hash in crypto_hash_setkey() from sctp_auth_calculate_hmac(). To close the loop: asoc->asoc_shared_key is freshly allocated secret material and independant of the sctp_shared_key management keeping track of only shared keys in endpoints and assocs. Hence, also commit 4184b2a7 ("net: sctp: fix memory leak in auth key management") is independant of this bug here since it concerns a different layer (though same structures being used eventually). asoc->asoc_shared_key is reference dropped correctly on assoc destruction in sctp_association_free() and when active keys are being replaced in sctp_auth_asoc_init_active_key(), it always has a refcount of 1. Hence, it's freed prematurely in sctp_assoc_update(). Simple fix is to remove that sctp_auth_key_put() from there which fixes these panics.
