pop_wait is used to determine if a deferred playback close needs to be cancelled when the a PCM is open or if after the power-down delay expires it needs to run. pop_wait is associated with the CODEC DAI, so the CODEC DAI must be unique. This holds true for most CODECs, except for the dummy CODEC and its DAI. In DAI links with non-unique dummy CODECs (e.g. front-ends), pop_wait can be overwritten by another DAI link using also a dummy CODEC. Failure to cancel a deferred close can cause mute due to the DAPM STOP event sent in the deferred work. One scenario where pop_wait is overwritten and causing mute is below (where hw:0,0 and hw:0,1 are two front-ends with default pmdown_time = 5 secs): aplay /dev/urandom -D hw:0,0 -c 2 -r 48000 -f S16_LE -d 1 sleep 1 aplay /dev/urandom -D hw:0,1 -c 2 -r 48000 -f S16_LE -d 3 & aplay /dev/urandom -D hw:0,0 -c 2 -r 48000 -f S16_LE Since CODECs may not be unique, pop_wait is moved to the PCM runtime structure. Creating separate dummy CODECs for each DAI link can also solve the problem, but at this point it's only pop_wait variable in the CODEC DAI that has negative effects by not being unique.

Pull networking fixes from David Miller: 1) Netlink socket dumping had several missing verifications and checks. In particular, address comparisons in the request byte code interpreter could access past the end of the address in the inet_request_sock. Also, address family and address prefix lengths were not validated properly at all. This means arbitrary applications can read past the end of certain kernel data structures. Fixes from Neal Cardwell. 2) ip_check_defrag() operates in contexts where we're in the process of, or about to, input the packet into the real protocols (specifically macvlan and AF_PACKET snooping). Unfortunately, it does a pskb_may_pull() which can modify the backing packet data which is not legal if the SKB is shared. It very much can be shared in this context. Deal with the possibility that the SKB is segmented by using skb_copy_bits(). Fix from Johannes Berg based upon a report by Eric Leblond. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: ipv4: ip_check_defrag must not modify skb before unsharing inet_diag: validate port comparison byte code to prevent unsafe reads inet_diag: avoid unsafe and nonsensical prefix matches in inet_diag_bc_run() inet_diag: validate byte code to prevent oops in inet_diag_bc_run() inet_diag: fix oops for IPv4 AF_INET6 TCP SYN-RECV state

This reverts commits a5091539 and d7c3b937. This is a revert of a revert of a revert. In addition, it reverts the even older i915 change to stop using the __GFP_NO_KSWAPD flag due to the original commits in linux-next. It turns out that the original patch really was bogus, and that the original revert was the correct thing to do after all. We thought we had fixed the problem, and then reverted the revert, but the problem really is fundamental: waking up kswapd simply isn't the right thing to do, and direct reclaim sometimes simply _is_ the right thing to do. When certain allocations fail, we simply should try some direct reclaim, and if that fails, fail the allocation. That's the right thing to do for THP allocations, which can easily fail, and the GPU allocations want to do that too. So starting kswapd is sometimes simply wrong, and removing the flag that said "don't start kswapd" was a mistake. Let's hope we never revisit this mistake again - and certainly not this many times ;) Acked-by: Mel Gorman <mgorman@suse.de> Acked-by: Johannes Weiner <hannes@cmpxchg.org> Cc: Rik van Riel <riel@redhat.com> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

ip_check_defrag() might be called from af_packet within the RX path where shared SKBs are used, so it must not modify the input SKB before it has unshared it for defragmentation. Use skb_copy_bits() to get the IP header and only pull in everything later. The same is true for the other caller in macvlan as it is called from dev->rx_handler which can also get a shared SKB.

This reverts commit 782fd304. We are going to reinstate the __GFP_NO_KSWAPD flag that has been removed, the removal reverted, and then removed again. Making this commit a pointless fixup for a problem that was caused by the removal of __GFP_NO_KSWAPD flag. The thing is, we really don't want to wake up kswapd for THP allocations (because they fail quite commonly under any kind of memory pressure, including when there is tons of memory free), and these patches were just trying to fix up the underlying bug: the original removal of __GFP_NO_KSWAPD in commit c6543459 ("mm: remove __GFP_NO_KSWAPD") was simply bogus.

Add logic to verify that a port comparison byte code operation actually has the second inet_diag_bc_op from which we read the port for such operations. Previously the code blindly referenced op[1] without first checking whether a second inet_diag_bc_op struct could fit there. So a malicious user could make the kernel read 4 bytes beyond the end of the bytecode array by claiming to have a whole port comparison byte code (2 inet_diag_bc_op structs) when in fact the bytecode was not long enough to hold both.

Add logic to check the address family of the user-supplied conditional and the address family of the connection entry. We now do not do prefix matching of addresses from different address families (AF_INET vs AF_INET6), except for the previously existing support for having an IPv4 prefix match an IPv4-mapped IPv6 address (which this commit maintains as-is). This change is needed for two reasons: (1) The addresses are different lengths, so comparing a 128-bit IPv6 prefix match condition to a 32-bit IPv4 connection address can cause us to unwittingly walk off the end of the IPv4 address and read garbage or oops. (2) The IPv4 and IPv6 address spaces are semantically distinct, so a simple bit-wise comparison of the prefixes is not meaningful, and would lead to bogus results (except for the IPv4-mapped IPv6 case, which this commit maintains).

Add logic to validate INET_DIAG_BC_S_COND and INET_DIAG_BC_D_COND operations. Previously we did not validate the inet_diag_hostcond, address family, address length, and prefix length. So a malicious user could make the kernel read beyond the end of the bytecode array by claiming to have a whole inet_diag_hostcond when the bytecode was not long enough to contain a whole inet_diag_hostcond of the given address family. Or they could make the kernel read up to about 27 bytes beyond the end of a connection address by passing a prefix length that exceeded the length of addresses of the given family.

Fix inet_diag to be aware of the fact that AF_INET6 TCP connections instantiated for IPv4 traffic and in the SYN-RECV state were actually created with inet_reqsk_alloc(), instead of inet6_reqsk_alloc(). This means that for such connections inet6_rsk(req) returns a pointer to a random spot in memory up to roughly 64KB beyond the end of the request_sock. With this bug, for a server using AF_INET6 TCP sockets and serving IPv4 traffic, an inet_diag user like `ss state SYN-RECV` would lead to inet_diag_fill_req() causing an oops or the export to user space of 16 bytes of kernel memory as a garbage IPv6 address, depending on where the garbage inet6_rsk(req) pointed.
