When we use 'nft -f' to submit rules, it will build multiple rules into
one netlink skb to send to kernel, kernel will process them one by one.
meanwhile, it add the trans into commit_list to record every commit.
if one of them's return value is -EAGAIN, status |= NFNL_BATCH_REPLAY
will be marked. after all the process is done. it will roll back all the
commits.
now kernel use list_add_tail to add trans to commit, and use
list_for_each_entry_safe to roll back. which means the order of adding
and rollback is the same. that will cause some cases cannot work well,
even trigger call trace, like:
1. add a set into table foo [return -EAGAIN]:
commit_list = 'add set trans'
2. del foo:
commit_list = 'add set trans' -> 'del set trans' -> 'del tab trans'
then nf_tables_abort will be called to roll back:
firstly process 'add set trans':
case NFT_MSG_NEWSET:
trans->ctx.table->use--;
list_del_rcu(&nft_trans_set(trans)->list);
it will del the set from the table foo, but it has removed when del
table foo [step 2], then the kernel will panic.
the right order of rollback should be:
'del tab trans' -> 'del set trans' -> 'add set trans'.
which is opposite with commit_list order.
so fix it by rolling back commits with reverse order in nf_tables_abort.

Jan Stancek reported that I wrecked things for him by fixing things for Vladimir :/ His report was due to an UNINTERRUPTIBLE wait getting -EINTR, which should not be possible, however my previous patch made this possible by unconditionally checking signal_pending(). We cannot use current->state as was done previously, because the instruction after the store to that variable it can be changed. We must instead pass the initial state along and use that.

The VRF driver cycles netdevs when an interface is enslaved or released: the down event is used to flush neighbor and route tables and the up event (if the interface was already up) effectively moves local and connected routes to the proper table. As of 4f823de the local route is left hanging around after a link down, so when a netdev is moved from one VRF to another (or released from a VRF altogether) local routes are left in the wrong table. Fix by handling the NETDEV_CHANGEUPPER event. When the upper dev is an L3mdev then call fib_disable_ip to flush all routes, local ones to.

…onFly AudioQuest DragonFly DAC reports a volume control range of 0..50 (0x0000..0x0032) which in USB Audio means a range of 0 .. 0.2dB, which is obviously incorrect and would cause software using the dB information in e.g. volume sliders to have a massive volume difference in 100..102% range. Commit 2d1cb7f ("ALSA: usb-audio: add dB range mapping for some devices") added a dB range mapping for it with range 0..50 dB. However, the actual volume mapping seems to be neither linear volume nor linear dB scale, but instead quite close to the cubic mapping e.g. alsamixer uses, with a range of approx. -53...0 dB. Replace the previous quirk with a custom dB mapping based on some basic output measurements, using a 10-item range TLV (which will still fit in alsa-lib MAX_TLV_RANGE_SIZE). Tested on AudioQuest DragonFly HW v1.2. The quirk is only applied if the range is 0..50, so if this gets fixed/changed in later HW revisions it will no longer be applied. v2: incorporated Takashi Iwai's suggestion for the quirk application method Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

Pablo Neira Ayuso says: ==================== netfilter fixes for net The following patchset contains Netfilter fixes for you net tree, specifically for nf_tables and nfnetlink_queue, they are: 1) Avoid a compilation warning in nfnetlink_queue that was introduced in the previous merge window with the simplification of the conntrack integration, from Arnd Bergmann. 2) nfnetlink_queue is leaking the pernet subsystem registration from a failure path, patch from Nikolay Borisov. 3) Pass down netns pointer to batch callback in nfnetlink, this is the largest patch and it is not a bugfix but it is a dependency to resolve a splat in the correct way. 4) Fix a splat due to incorrect socket memory accounting with nfnetlink skbuff clones. 5) Add missing conntrack dependencies to NFT_DUP_IPV4 and NFT_DUP_IPV6. 6) Traverse the nftables commit list in reverse order from the commit path, otherwise we crash when the user applies an incremental update via 'nft -f' that deletes an object that was just introduced in this batch, from Xin Long. Regarding the compilation warning fix, many people have sent us (and keep sending us) patches to address this, that's why I'm including this batch even if this is not critical. ==================== Signed-off-by: David S.

郭永刚 reported that one could simply crash the kernel as root by using a simple program: int socket_fd; struct sockaddr_in addr; addr.sin_port = 0; addr.sin_addr.s_addr = INADDR_ANY; addr.sin_family = 10; socket_fd = socket(10,3,0x40000000); connect(socket_fd , &addr,16); AF_INET, AF_INET6 sockets actually only support 8-bit protocol identifiers. inet_sock's skc_protocol field thus is sized accordingly, thus larger protocol identifiers simply cut off the higher bits and store a zero in the protocol fields. This could lead to e.g. NULL function pointer because as a result of the cut off inet_num is zero and we call down to inet_autobind, which is NULL for raw sockets. kernel: Call Trace: kernel: [<ffffffff816db90e>] ? inet_autobind+0x2e/0x70 kernel: [<ffffffff816db9a4>] inet_dgram_connect+0x54/0x80 kernel: [<ffffffff81645069>] SYSC_connect+0xd9/0x110 kernel: [<ffffffff810ac51b>] ? ptrace_notify+0x5b/0x80 kernel: [<ffffffff810236d8>] ? syscall_trace_enter_phase2+0x108/0x200 kernel: [<ffffffff81645e0e>] SyS_connect+0xe/0x10 kernel: [<ffffffff81779515>] tracesys_phase2+0x84/0x89 I found no particular commit which introduced this problem.

dwmac-sunxi has 2 callbacks that were called from stmmac_platform as part of the probe and remove sequences. Ater the conversion of dwmac-sunxi into a standalone platform driver, the .init function is called before calling into the stmmac driver core, but .exit is not called to clean up if stmmac returns an error. This patch fixes the probe error path. This properly cleans up and releases resources when the driver core fails to probe.

The way the mode probing works is this: 1. All modes currently on the mode list are marked as UNVERIFIED 2. New modes are on the probed_modes list (they start with status OK) 3. Modes are moved from the probed_modes list to the actual mode list. If a mode already on the mode list is deemed to match one of the probed modes, the duplicate is dropped and the mode status updated to OK. After this the probed_modes list will be empty. 4. All modes on the mode list are verified to not violate any constraints. Any that do are marked as such. 5. Any mode left with a non-OK status is pruned from the list, with an appropriate debug message. What all this means is that any mode on the original list that didn't have a duplicate on the probed_modes list, should be left with status UNVERFIED (or previously could have been left with some other status, but never OK). I broke that in commit 05acaec ("drm: Reorganize probed mode validation") by always assigning something to the mode->status during the validation step. So any mode from the old list that still passed the validation would be left on the list with status OK in the end. Fix this by not doing the basic mode validation unless the mode already has status OK (meaning it came from the probed_modes list, or at least a duplicate of it was on that list). This way we will correctly prune away any mode from the old mode list that didn't appear on the probed_modes list.
