The sco_send_frame() also takes lock_sock() during memcpy_from_msg() call that may be endlessly blocked by a task with userfaultd technique, and this will result in a hung task watchdog trigger. Just like the similar fix for hci_sock_sendmsg() in commit 92c685dc5de0 ("Bluetooth: reorganize functions..."), this patch moves the memcpy_from_msg() out of lock_sock() for addressing the hang. This should be the last piece for fixing CVE-2021-3640 after a few already queued fixes. Signed-off-by:Takashi Iwai <tiwai@suse.de> Signed-off-by:

These checks are still not strict enough. The main problem is that if "cb->type == QRTR_TYPE_NEW_SERVER" is true then "len - hdrlen" is guaranteed to be 4 but we need to be at least 16 bytes. In fact, we can reject everything smaller than sizeof(*pkt) which is 20 bytes. Also I don't like the ALIGN(size, 4). It's better to just insist that data is needs to be aligned at the start.

Eric Dumazet says: ==================== inet: make exception handling less predictible This second round of patches is addressing Keyu Man recommendations to make linux hosts more robust against a class of brute force attacks. ==================== Signed-off-by: -
Eric Dumazet authored
Even after commit 6457378f ("ipv4: use siphash instead of Jenkins in fnhe_hashfun()"), an attacker can still use brute force to learn some secrets from a victim linux host. One way to defeat these attacks is to make the max depth of the hash table bucket a random value. Before this patch, each bucket of the hash table used to store exceptions could contain 6 items under attack. After the patch, each bucket would contains a random number of items, between 6 and 10. The attacker can no longer infer secrets. This is slightly increasing memory size used by the hash table, by 50% in average, we do not expect this to be a problem. This patch is more complex than the prior one (IPv6 equivalent), because IPv4 was reusing the oldest entry. Since we need to be able to evict more than one entry per update_or_create_fnhe() call, I had to replace fnhe_oldest() with fnhe_remove_oldest(). Also note that we will queue extra kfree_rcu() calls under stress, which hopefully wont be a too big issue. Fixes: 4895c771 ("ipv4: Add FIB nexthop exceptions.") Signed-off-by:

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for net-next: 1) Clean up and consolidate ct ecache infrastructure by merging ct and expect notifiers, from Florian Westphal. 2) Missing counters and timestamp in nfnetlink_queue and _log conntrack information. 3) Missing error check for xt_register_template() in iptables mangle, as a incremental fix for the previous pull request, also from Florian Westphal. 4) Add netfilter hooks for the SRv6 lightweigh tunnel driver, from Ryoga Sato. The hooks are enabled via nf_hooks_lwtunnel sysctl to make sure existing netfilter rulesets do not break. There is a static key to disable the hooks by default.

The driver is being passed interrupts, then looking up the same interrupts as GPIOs a second time to convert them into interrupts and set properties on them. This is pointless: the GPIO and irqchip APIs of a GPIO chip are orthogonal. Just request the interrupts and be done with it, drop reliance on any GPIO functions or definitions. Use devres-managed functions and add a small devress quirk to unregister the clock as well and we can rely on devres to handle all the resources and cut down a bunch of boilerplate in the process.

After the recent ixp4xx cleanups, the ptp driver has gained a build failure in some configurations: drivers/net/ethernet/xscale/ptp_ixp46x.c: In function 'ptp_ixp_init': drivers/net/ethernet/xscale/ptp_ixp46x.c:290:51: error: 'IXP4XX_TIMESYNC_BASE_VIRT' undeclared (first use in this function) Avoid the last bit of hardcoded constants from platform headers by turning the ptp driver bit into a platform driver and passing the IRQ and MMIO address as resources. This is a bit tricky: - The interface between the two drivers is now the new ixp46x_ptp_find() function, replacing the global ixp46x_phc_index variable. The call is done as late as possible, in hwtstamp_set(), to ensure that the ptp device is fully probed. - As the ptp driver is now called by the network driver, the link dependency is reversed, which in turn requires a small Makefile hack - The GPIO number is still left hardcoded. This is clearly not great, but it can be addressed later. Note that commit 98ac0cc2 ("ARM: ixp4xx: Convert to MULTI_IRQ_HANDLER") changed the IRQ number to something meaningless. Passing the correct IRQ in a resource fixes this. - When the PTP driver is disabled, ethtool .get_ts_info() now correctly lists only software timestamping regardless of the hardware. Signed-off-by:

Michael Chan says: ==================== bnxt_en: Implement new driver APIs to send FW messages The current driver APIs to send messages to the firmware allow only one outstanding message in flight. There is only one buffer for the firmware response for each firmware channel. To send a firmware message, all callers must take a mutex and it is released after the firmware response has been read. This scheme does not allow multiple firmware messages in flight. Firmware may take a long time to respond to some messages (e.g. NVRAM related ones) and this causes the mutex to be held for a long time, blocking other callers. This patchset intoduces the new driver APIs to address the above shortcomings. The new APIs are compatible with new and old firmware. But the new deferred firmware response mechanism will require newer firmware in order to allow multiple outstanding firmware commands. All callers are updated to use the new APIs. v2: Patch 4 and patch 9 updated to fix issues reported by test robot ==================== Signed-off-by:
