The user-provided value to setsockopt(SO_RCVLOWAT) can be larger than the maximum possible receive buffer. Such values mute POLLIN signals on the socket which can stall progress on the socket. Limit the user-provided value to half of the maximum receive buffer, i.e., half of sk_rcvbuf when the receive buffer size is set by the user, or otherwise half of sysctl_tcp_rmem[2].

DP83620 register set is compatible with the DP83848, but it also supports 100base-FX. When the hardware is configured such as that fiber mode is enabled, autonegotiation is not possible. The chip, however, doesn't expose this information via BMSR_ANEGCAPABLE. Instead, this bit is always set high, even if the particular hardware configuration makes it so that auto negotiation is not possible [1]. Under these circumstances, the phy subsystem keeps trying for autonegotiation to happen, without success. Hereby, we inspect BMCR_ANENABLE bit after genphy_config_init, which on reset is set to 0 when auto negotiation is disabled, and so we use this value instead of BMSR_ANEGCAPABLE.

fchownat() doesn't even hold refcnt of fd until it figures out fd is really needed (otherwise is ignored) and releases it after it resolves the path. This means sock_close() could race with sockfs_setattr(), which leads to a NULL pointer dereference since typically we set sock->sk to NULL in ->release(). As pointed out by Al, this is unique to sockfs. So we can fix this in socket layer by acquiring inode_lock in sock_close() and checking against NULL in sockfs_setattr(). sock_release() is called in many places, only the sock_close() path matters here. And fortunately, this should not affect normal sock_close() as it is only called when the last fd refcnt is gone. It only affects sock_close() with a parallel sockfs_setattr() in progress, which is not common. Fixes: 86741ec2 ("net: core: Add a UID field to struct sock.") Reported-by:

Pull x86 updates and fixes from Thomas Gleixner: - Fix the (late) fallout from the vector management rework causing hlist corruption and irq descriptor reference leaks caused by a missing sanity check. The straight forward fix triggered another long standing issue to surface. The pre rework code hid the issue due to being way slower, but now the chance that user space sees an EBUSY error return when updating irq affinities is way higher, though quite a bunch of userspace tools do not handle it properly despite the fact that EBUSY could be returned for at least 10 years. It turned out that the EBUSY return can be avoided completely by utilizing the existing delayed affinity update mechanism for irq remapped scenarios as well. That's a bit more error handling in the kernel, but avoids fruitless fingerpointing discussions with tool developers. - Decouple PHYSICAL_MASK from AMD SME as its going to be required for the upcoming Intel memory encryption support as well. - Handle legacy device ACPI detection properly for newer platforms - Fix the wrong argument ordering in the vector allocation tracepoint - Simplify the IDT setup code for the APIC=n case - Use the proper string helpers in the MTRR code - Remove a stale unused VDSO source file - Convert the microcode update lock to a raw spinlock as its used in atomic context. * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/intel_rdt: Enable CMT and MBM on new Skylake stepping x86/apic/vector: Print APIC control bits in debugfs genirq/affinity: Defer affinity setting if irq chip is busy x86/platform/uv: Use apic_ack_irq() x86/ioapic: Use apic_ack_irq() irq_remapping: Use apic_ack_irq() x86/apic: Provide apic_ack_irq() genirq/migration: Avoid out of line call if pending is not set genirq/generic_pending: Do not lose pending affinity update x86/apic/vector: Prevent hlist corruption and leaks x86/vector: Fix the args of vector_alloc tracepoint x86/idt: Simplify the idt_setup_apic_and_irq_gates() x86/platform/uv: Remove extra parentheses x86/mm: Decouple dynamic __PHYSICAL_MASK from AMD SME x86: Mark native_set_p4d() as __always_inline x86/microcode: Make the late update update_lock a raw lock for RT x86/mtrr: Convert to use strncpy_from_user() helper x86/mtrr: Convert to use match_string() helper x86/vdso: Remove unused file x86/i8237: Register device based on FADT legacy boot flag

Commit a841796f ("signal: align __lock_task_sighand() irq disabling and RCU") introduced a rcu read side critical section with interrupts disabled. The changelog suggested that a better long-term fix would be "to make rt_mutex_unlock() disable irqs when acquiring the rt_mutex structure's ->wait_lock". This long-term fix has been made in commit b4abf910 ("rtmutex: Make wait_lock irq safe") for a different reason. Therefore revert commit a841796f ("signal: align > __lock_task_sighand() irq disabling and RCU") as the interrupt disable dance is not longer required. The change was tested on the base of b4abf910 ("rtmutex: Make wait_lock irq safe") with a four hour run of rcutorture scenario TREE03 with lockdep enabled as suggested by Paul McKenney.

Merge proc_cmdline simplifications. This re-writes the get_mm_cmdline() logic to be rather simpler than it used to be, and makes the semantics for "cmdline goes past the end of the original area" more natural. You _can_ use prctl(PR_SET_MM) to just point your command line somewhere else entirely, but the traditional model is to just edit things in place and that still needs to continue to work. At least this way the code makes some sense. * proc-cmdline: fs/proc: simplify and clarify get_mm_cmdline() function fs/proc: re-factor proc_pid_cmdline_read() a bit

The majority of the diff goes to two SoCs, Actions Semi and Qualcomm.

Pull staging/IIO updates from Greg KH: "Here is the big staging and IIO driver update for 4.18-rc1. It was delayed as I wanted to make sure the final driver deletions did not cause any major merge issues, and all now looks good. There are a lot of patches here, just over 1000. The diffstat summary shows the major changes here: 1007 files changed, 16828 insertions(+), 227770 deletions(-) Because of this, we might be close to shrinking the overall kernel source code size for two releases in a row. There was loads of work in this release cycle, primarily: - tons of ks7010 driver cleanups - lots of mt7621 driver fixes and cleanups - most driver cleanups - wilc1000 fixes and cleanups - lots and lots of IIO driver cleanups and new additions - debugfs cleanups for all staging drivers - lots of other staging driver cleanups and fixes, the shortlog has the full details. but the big user-visable things here are the removal of 3 chunks of code: - ncpfs and ipx were removed on schedule, no one has cared about this code since it moved to staging last year, and if it needs to come back, it can be reverted. - lustre file system is removed. I've ranted at the lustre developers about once a year for the past 5 years, with no real forward progress at all to clean things up and get the code into the "real" part of the kernel. Given that the lustre developers continue to work on an external tree and try to port those changes to the in-kernel tree every once in a while, this whole thing really really is not working out at all. So I'm deleting it so that the developers can spend the time working in their out-of-tree location and get things cleaned up properly to get merged into the tree correctly at a later date. Because of these file removals, you will have merge issues on some of these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the atomisp driver). Just delete those files, it's a simple merge :) All of this has been in linux-next for a while with no reported problems" * tag 'staging-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1011 commits) staging: ipx: delete it from the tree ncpfs: remove uapi .h files ncpfs: remove Documentation ncpfs: remove compat functionality staging: ncpfs: delete it staging: lustre: delete the filesystem from the tree. staging: vc04_services: no need to save the log debufs dentries staging: vc04_services: vchiq_debugfs_log_entry can be a void * staging: vc04_services: remove struct vchiq_debugfs_info staging: vc04_services: move client dbg directory into static variable staging: vc04_services: remove odd vchiq_debugfs_top() wrapper staging: vc04_services: no need to check debugfs return values staging: mt7621-gpio: reorder includes alphabetically staging: mt7621-gpio: change gc_map to don't use pointers staging: mt7621-gpio: use GPIOF_DIR_OUT and GPIOF_DIR_IN macros instead of custom values staging: mt7621-gpio: change 'to_mediatek_gpio' to make just a one line return staging: mt7621-gpio: dt-bindings: update documentation for #interrupt-cells property staging: mt7621-gpio: update #interrupt-cells for the gpio node staging: mt7621-gpio: dt-bindings: complete documentation for the gpio staging: mt7621-dts: add missing properties to gpio node ...

Pull libnvdimm updates from Dan Williams: "This adds a user for the new 'bytes-remaining' updates to memcpy_mcsafe() that you already received through Ingo via the x86-dax- for-linus pull. Not included here, but still targeting this cycle, is support for handling memory media errors (poison) consumed via userspace dax mappings. Summary: - DAX broke a fundamental assumption of truncate of file mapped pages. The truncate path assumed that it is safe to disconnect a pinned page from a file and let the filesystem reclaim the physical block. With DAX the page is equivalent to the filesystem block. Introduce dax_layout_busy_page() to enable filesystems to wait for pinned DAX pages to be released. Without this wait a filesystem could allocate blocks under active device-DMA to a new file. - DAX arranges for the block layer to be bypassed and uses dax_direct_access() + copy_to_iter() to satisfy read(2) calls. However, the memcpy_mcsafe() facility is available through the pmem block driver. In order to safely handle media errors, via the DAX block-layer bypass, introduce copy_to_iter_mcsafe(). - Fix cache management policy relative to the ACPI NFIT Platform Capabilities Structure to properly elide cache flushes when they are not necessary.

Callers of br_fdb_find() need to hold the hash lock, which br_fdb_find_port() doesn't do. However, since br_fdb_find_port() is not doing any actual FDB manipulation, the hash lock is not really needed at all. So convert to br_fdb_find_rcu(), surrounded by rcu_read_lock() / _unlock() pair. The device pointer copied from inside the FDB entry is then kept alive by the RTNL lock, which br_fdb_find_port() asserts.

After commit 6b229cf7 ("udp: add batching to udp_rmem_release()") the sk_rmem_alloc field does not measure exactly anymore the receive queue length, because we batch the rmem release. The issue is really apparent only after commit 0d4a6608 ("udp: do rmem bulk free even if the rx sk queue is empty"): the user space can easily check for an empty socket with not-0 queue length reported by the 'ss' tool or the procfs interface. We need to use a custom UDP helper to report the correct queue length, taking into account the forward allocation deficit.

Commit 4a0e3e98 ("cdc_ncm: Add support for moving NDP to end of NCM frame") added logic to reserve space for the NDP at the end of the NTB/skb. This reservation did not take the final alignment of the NDP into account, causing us to reserve too little space. Additionally the padding prior to NDP addition did not ensure there was enough space for the NDP. The NTB/skb with the NDP appended would then exceed the configured max size. This caused the final padding of the NTB to use a negative count, padding to almost INT_MAX, and resulting in: [60103.825970] BUG: unable to handle kernel paging request at ffff9641f2004000 [60103.825998] IP: __memset+0x24/0x30 [60103.826001] PGD a6a06067 P4D a6a06067 PUD 4f65a063 PMD 72003063 PTE 0 [60103.826013] Oops: 0002 [#1] SMP NOPTI [60103.826018] Modules linked in: (removed( [60103.826158] CPU: 0 PID: 5990 Comm: Chrome_DevTools Tainted: G O 4.14.0-3-amd64 #1 Debian 4.14.17-1 [60103.826162] Hardware name: LENOVO 20081 BIOS 41CN28WW(V2.04) 05/03/2012 [60103.826166] task: ffff964193484fc0 task.stack: ffffb2890137c000 [60103.826171] RIP: 0010:__memset+0x24/0x30 [60103.826174] RSP: 0000:ffff964316c03b68 EFLAGS: 00010216 [60103.826178] RAX: 0000000000000000 RBX: 00000000fffffffd RCX: 000000001ffa5000 [60103.826181] RDX: 0000000000000005 RSI: 0000000000000000 RDI: ffff9641f2003ffc [60103.826184] RBP: ffff964192f6c800 R08: 00000000304d434e R09: ffff9641f1d2c004 [60103.826187] R10: 0000000000000002 R11: 00000000000005ae R12: ffff9642e6957a80 [60103.826190] R13: ffff964282ff2ee8 R14: 000000000000000d R15: ffff9642e4843900 [60103.826194] FS: 00007f395aaf6700(0000) GS:ffff964316c00000(0000) knlGS:0000000000000000 [60103.826197] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [60103.826200] CR2: ffff9641f2004000 CR3: 0000000013b0c000 CR4: 00000000000006f0 [60103.826204] Call Trace: [60103.826212] <IRQ> [60103.826225] cdc_ncm_fill_tx_frame+0x5e3/0x740 [cdc_ncm] [60103.826236] cdc_ncm_tx_fixup+0x57/0x70 [cdc_ncm] [60103.826246] usbnet_start_xmit+0x5d/0x710 [usbnet] [60103.826254] ? netif_skb_features+0x119/0x250 [60103.826259] dev_hard_start_xmit+0xa1/0x200 [60103.826267] sch_direct_xmit+0xf2/0x1b0 [60103.826273] __dev_queue_xmit+0x5e3/0x7c0 [60103.826280] ? ip_finish_output2+0x263/0x3c0 [60103.826284] ip_finish_output2+0x263/0x3c0 [60103.826289] ? ip_output+0x6c/0xe0 [60103.826293] ip_output+0x6c/0xe0 [60103.826298] ? ip_forward_options+0x1a0/0x1a0 [60103.826303] tcp_transmit_skb+0x516/0x9b0 [60103.826309] tcp_write_xmit+0x1aa/0xee0 [60103.826313] ? sch_direct_xmit+0x71/0x1b0 [60103.826318] tcp_tasklet_func+0x177/0x180 [60103.826325] tasklet_action+0x5f/0x110 [60103.826332] __do_softirq+0xde/0x2b3 [60103.826337] irq_exit+0xae/0xb0 [60103.826342] do_IRQ+0x81/0xd0 [60103.826347] common_interrupt+0x98/0x98 [60103.826351] </IRQ> [60103.826355] RIP: 0033:0x7f397bdf2282 [60103.826358] RSP: 002b:00007f395aaf57d8 EFLAGS: 00000206 ORIG_RAX: ffffffffffffff6e [60103.826362] RAX: 0000000000000000 RBX: 00002f07bc6d0900 RCX: 00007f39752d7fe7 [60103.826365] RDX: 0000000000000022 RSI: 0000000000000147 RDI: 00002f07baea02c0 [60103.826368] RBP: 0000000000000001 R08: 0000000000000000 R09: 0000000000000000 [60103.826371] R10: 00000000ffffffff R11: 0000000000000000 R12: 00002f07baea02c0 [60103.826373] R13: 00002f07bba227a0 R14: 00002f07bc6d090c R15: 0000000000000000 [60103.826377] Code: 90 90 90 90 90 90 90 0f 1f 44 00 00 49 89 f9 48 89 d1 83 e2 07 48 c1 e9 03 40 0f b6 f6 48 b8 01 01 01 01 01 01 01 01 48 0f af c6 <f3> 48 ab 89 d1 f3 aa 4c 89 c8 c3 90 49 89 f9 40 88 f0 48 89 d1 [60103.826442] RIP: __memset+0x24/0x30 RSP: ffff964316c03b68 [60103.826444] CR2: ffff9641f2004000 Commit e1069bbf ("net: cdc_ncm: Reduce memory use when kernel memory low") made this bug much more likely to trigger by reducing the NTB size under memory pressure.

The problem here is that set_bit() and test_bit() take a bit number so we should be passing 0 but instead we're passing (1 << 0) which leads to a double shift. It doesn't cause a runtime bug in the current code because it's done consistently and we only set that one bit. I decided to just re-use NVME_AER_NOTICE_NS_CHANGED instead of introducing a new define for this. Signed-off-by:
