[ Upstream commit 468479e6 ] PACKET_FANOUT_LB computes f->rr_cur such that it is modulo f->num_members. It returns the old value unconditionally, but f->num_members may have changed since the last store. Ensure that the return value is always < num. When modifying the logic, simplify it further by replacing the loop with an unconditional atomic increment. Fixes: dc99f600 ("packet: Add fanout support.") Suggested-by:

[ Upstream commit f98f4514 ] We need to tell compiler it must not read f->num_members multiple times. Otherwise testing if num is not zero is flaky, and we could attempt an invalid divide by 0 in fanout_demux_cpu() Note bug was present in packet_rcv_fanout_hash() and packet_rcv_fanout_lb() but final 3.1 had a simple location after commit 95ec3eb4 ("packet: Add 'cpu' fanout policy.")

[ Upstream commit 2dab80a8 ] After the ->set() spinlocks were removed br_stp_set_bridge_priority was left running without any protection when used via sysfs. It can race with port add/del and could result in use-after-free cases and corrupted lists. Tested by running port add/del in a loop with stp enabled while setting priority in a loop, crashes are easily reproducible. The spinlocks around sysfs ->set() were removed in commit: 14f98f25 ("bridge: range check STP parameters") There's also a race condition in the netlink priority support that is fixed by this change, but it was introduced recently and the fixes tag covers it, just in case it's needed the commit is: af615762 ("bridge: add ageing_time, stp_state, priority over netlink") Signed-off-by:

[ Upstream commit 2d45a02d ] ->auto_asconf_splist is per namespace and mangled by functions like sctp_setsockopt_auto_asconf() which doesn't guarantee any serialization. Also, the call to inet_sk_copy_descendant() was backuping ->auto_asconf_list through the copy but was not honoring ->do_auto_asconf, which could lead to list corruption if it was different between both sockets. This commit thus fixes the list handling by using ->addr_wq_lock spinlock to protect the list. A special handling is done upon socket creation and destruction for that. Error handlig on sctp_init_sock() will never return an error after having initialized asconf, so sctp_destroy_sock() can be called without addrq_wq_lock. The lock now will be take on sctp_close_sock(), before locking the socket, so we don't do it in inverse order compared to sctp_addr_wq_timeout_handler(). Instead of taking the lock on sctp_sock_migrate() for copying and restoring the list values, it's preferred to avoid rewritting it by implementing sctp_copy_descendant(). Issue was found with a test application that kept flipping sysctl default_auto_asconf on and off, but one could trigger it by issuing simultaneous setsockopt() calls on multiple sockets or by creating/destroying sockets fast enough. This is only triggerable locally. Fixes: 9f7d653b ("sctp: Add Auto-ASCONF support (core).") Reported-by:

[ Upstream commit fb05e7a8 ] We saw excessive direct memory compaction triggered by skb_page_frag_refill. This causes performance issues and add latency. Commit 5640f768 introduces the order-3 allocation. According to the changelog, the order-3 allocation isn't a must-have but to improve performance. But direct memory compaction has high overhead. The benefit of order-3 allocation can't compensate the overhead of direct memory compaction. This patch makes the order-3 page allocation atomic. If there is no memory pressure and memory isn't fragmented, the alloction will still success, so we don't sacrifice the order-3 benefit here. If the atomic allocation fails, direct memory compaction will not be triggered, skb_page_frag_refill will fallback to order-0 immediately, hence the direct memory compaction overhead is avoided. In the allocation failure case, kswapd is waken up and doing compaction, so chances are allocation could success next time. alloc_skb_with_frags is the same. The mellanox driver does similar thing, if this is accepted, we must fix the driver too. V3: fix the same issue in alloc_skb_with_frags as pointed out by Eric V2: make the changelog clearer Cc: Eric Dumazet <edumazet@google.com> Cc: Chris Mason <clm@fb.com> Cc: Debabrata Banerjee <dbavatar@gmail.com> Signed-off-by:

[ Upstream commit 1a040eac ] Since the addition of sysfs multicast router support if one set multicast_router to "2" more than once, then the port would be added to the hlist every time and could end up linking to itself and thus causing an endless loop for rlist walkers. So to reproduce just do: echo 2 > multicast_router; echo 2 > multicast_router; in a bridge port and let some igmp traffic flow, for me it hangs up in br_multicast_flood(). Fix this by adding a check in br_multicast_add_router() if the port is already linked. The reason this didn't happen before the addition of multicast_router sysfs entries is because there's a !hlist_unhashed check that prevents it. Signed-off-by:

commit d6c763af upstream. Since commit 8a0a9bd4 ('random: make get_random_int() more random'), get_random_int() returns a random value for each call, so comment and hack introduced in mmap_rnd() as part of commit 1d18c47c ('arm64: MMU fault handling and page table management') are incorrects. Commit 1d18c47c seems to use the same hack introduced by commit a5adc91a ('powerpc: Ensure random space between stack and mmaps'), latter copied in commit 5a0efea0 ('sparc64: Sharpen address space randomization calculations.'). But both architectures were cleaned up as part of commit fa8cbaaf ('powerpc+sparc64/mm: Remove hack in mmap randomize layout') as hack is no more needed since commit 8a0a9bd4. So the present patch removes the comment and the hack around get_random_int() on AArch64's mmap_rnd(). Cc: David S.

commit f104765b upstream. If hardware doesn't support DecodeAssist - a feature that provides more information about the intercept in the VMCB, KVM decodes the instruction and then updates the next_rip vmcb control field. However, NRIP support itself depends on cpuid Fn8000_000A_EDX[NRIPS]. Since skip_emulated_instruction() doesn't verify nrip support before accepting control.next_rip as valid, avoid writing this field if support isn't present. Signed-off-by:

commit 5f5bc6b1 upstream. Replacing a xattr consists of doing a lookup for its existing value, delete the current value from the respective leaf, release the search path and then finally insert the new value. This leaves a time window where readers (getxattr, listxattrs) won't see any value for the xattr. Xattrs are used to store ACLs, so this has security implications. This change also fixes 2 other existing issues which were: *) Deleting the old xattr value without verifying first if the new xattr will fit in the existing leaf item (in case multiple xattrs are packed in the same item due to name hash collision); *) Returning -EEXIST when the flag XATTR_CREATE is given and the xattr doesn't exist but we have have an existing item that packs muliple xattrs with the same name hash as the input xattr. In this case we should return ENOSPC. A test case for xfstests follows soon. Thanks to Alexandre Oliva for reporting the non-atomicity of the xattr replace implementation. Reported-by:

commit c80e5c0c upstream. On x86-64, __copy_instruction() always returns 0 (error) if the instruction uses %rip-relative addressing. This is because kernel_insn_init() is called the second time for 'insn' instance in such cases and sets all its fields to 0. Because of this, trying to place a kprobe on such instruction will fail, register_kprobe() will return -EINVAL. This patch fixes the problem. Signed-off-by:

pipe_iov_copy_{from,to}_user() may be tried twice with the same iovec, the first time atomically and the second time not. The second attempt needs to continue from the iovec position, pipe buffer offset and remaining length where the first attempt failed, but currently the pipe buffer offset and remaining length are reset. This will corrupt the piped data (possibly also leading to an information leak between processes) and may also corrupt kernel memory. This was fixed upstream by commits f0d1bec9 ("new helper: copy_page_from_iter()") and 637b58c2 ("switch pipe_read() to copy_page_to_iter()"), but those aren't suitable for stable. This fix for older kernel versions was made by Seth Jennings for RHEL and I have extracted it from their update.

commit 27f344eb upstream. Add a memory barrier to ensure the valid bit is read before any of the cqe payload is read. This fixes an issue seen on Power where the cqe payload was getting loaded before the valid bit. When this occurred, we saw an iotag out of range error when a command completed, but since the iotag looked invalid the command didn't get completed to scsi core. Later we hit the command timeout, attempted to abort the command, then waited for the aborted command to get returned. Since the adapter already returned the command, we timeout waiting, and end up escalating EEH all the way to host reset. This patch fixes this issue. Signed-off-by:

commit c4d69da1 upstream. Running igt, I was encountering the invalid TLB bug on my 845g, despite that it was using the CS workaround. Examining the w/a buffer in the error state, showed that the copy from the user batch into the workaround itself was suffering from the invalid TLB bug (the first cacheline was broken with the first two words reversed). Time to try a fresh approach. This extends the workaround to write into each page of our scratch buffer in order to overflow the TLB and evict the invalid entries. This could be refined to only do so after we update the GTT, but for simplicity, we do it before each batch. I suspect this supersedes our current workaround, but for safety keep doing both. V2: The magic number shall be 2. This doesn't conclusively prove that it is the mythical TLB bug we've been trying to workaround for so long, that it requires touching a number of pages to prevent the corruption indicates to me that it is TLB related, but the corruption (the reversed cacheline) is more subtle than a TLB bug, where we would expect it to read the wrong page entirely. Oh well, it prevents a reliable hang for me and so probably for others as well. Signed-off-by:

commit 43c1a0a9 upstream. Ignore Jabra GN9350E HID interface. USB audio is working nicely, but registering as HID blocks USB mouse buttons. Since special userspace programs are needed we will avoid attaching usbhid drivers in general. Signed-off-by:

commit adc23259 upstream. The Si4713 development board contains a Si4713 FM transmitter chip and is handled by the radio-usb-si4713 driver. The board reports itself as (10c4:8244) Cygnal Integrated Products, Inc. and misidentifies itself as a HID device in its USB interface descriptor. This patch ignores this device as an HID device and hence loads the custom driver. Signed-off-by:

commit 9b028649 upstream. The linux kernel has supported the TiVo Slide remote control for some time, but does not recognize the USB ID of the newer Slide Pro. This patch adds the missing data structures so the newer remote will be recognized by the driver, thereby allowing the TiVo, LiveTV, and Thumbs Up/Down buttons to be mapped with a hwdb file.

commit 5df4eb05 upstream. The report descriptor for the HOLTEK USB ID 04d9:a0c2 (ETEKCITY Scroll T-140 Gaming Mouse) is set to a very large amount of consumer usages (2^16), exceeding HID_MAX_USAGES. Added id, bindings and comments for the mouse, added to hid_have_special_driver, and reduced the usage and logical maximums to 0x2fff, consistent with the other mice in the category. Tested on the hardware. Signed-off-by:
