stmmac_tx_avail() may lie if used unprotected. It's using cur_tx and dirty_tx index. These index may be already in use by tx_clean when entering xmit routine. So, this should be called locked. This can cause transmit queue to be stuck, with following message: NETDEV WATCHDOG: eth0 (stmmaceth): transmit queue 0 timed out Signed-off-by:

drivers: net: ethernet: xilinx: xilinx_emaclite: revert the original commit "1db3ddff" Microblaze is a fpga soft core, it can be customized easily, which may cause many various hardware version strings. So the original fix patch based on hard-coded compatible version strings is not a good idea (although it is correct for current issue). For it, there will be a new solving way soon (which based on the device tree). The original issue is related with qemu, so can only change the hardware version string in qemu for it, then keep the original driver no touch ( qemu is for virtualization which has much easier life than real world).

When VLAN is in use in macvtap_put_user, we end up setting csum_start to the wrong place. The result is that the whoever ends up doing the checksum setting will corrupt the packet instead of writing the checksum to the expected location, usually this means writing the checksum with an offset of -4.

Herbert Xu authored
We set the flag TUN_PKT_STRIP if the user buffer provided is too small to contain the entire packet plus meta-data. However, this has been broken ever since we added GSO meta-data. VLAN acceleration also has the same problem. This patch fixes this by taking both into account when setting the TUN_PKT_STRIP flag. The fact that this has been broken for six years without anyone realising means that nobody actually uses this flag. Fixes: f43798c2 ("tun: Allow GSO using virtio_net_hdr") Signed-off-by:

The SMC91x is written to explicitly look up the IRQ resource from the platform device and extract the IRQ and flags, however the platform_get_irq() does additional things, like call of_irq_get() in the device tree case, which will translate the IRQ using the irqdomain and defer the probe if the IRQ host cannot be found. As we're not looking up the resource, this will not retrieve the IRQ flags, but that is better done using irqd_get_trigger_type(), as the trigger is what the driver wants to modify. We take care to preserve the semantics that will make the trigger type provided from the resource override any local specifier. Tested on the Nomadik NHK15 which has its SMC91x IRQ line connected to a STMPE2401 GPIO expander on I2C. Signed-off-by:

Florian Fainelli says: ==================== net: systemport: TX dma fixes This patch series contains two fixes for our transmit path, first one is a pretty nasty one since we were not allocating a large enough dma coherent pool for our transmit descriptors, which would work most of the time, since allocations are contiguous and we could have. Second patch fixes a less frequent, though highly likley crash when using CMA allocations. ==================== Signed-off-by: -

Callers of bcm_sysport_init_tx_ring() can currently fail, and will always call bcm_sysport_fini_tx_ring() in a loop ending at the number of TX queues (32) without checking if the TX ring was successfully initialized or not. Update bcm_sysport_fini_tx_ring() to return early and avoid a crash de-referencing ring->cbs if the TX ring was not initialized, since ring->cbs is the last part of the initialization done by bcm_sysport_init_tx_ring() that could fail.

Pull ACPI and power management fixes from Rafael Wysocki: "These are fixes received after my previous pull request plus one that has been in the works for quite a while, but its previous version caused problems to happen, so it's been deferred till now. Fixed are two recent regressions (MFD enumeration and cpufreq-dt), ACPI EC regression introduced in 3.17, system suspend error code path regression introduced in 3.15, an older bug related to recovery from failing resume from hibernation and a cpufreq-dt driver issue related to operation performance points. Specifics: - Fix a crash on r8a7791/koelsch during resume from system suspend caused by a recent cpufreq-dt commit (Geert Uytterhoeven). - Fix an MFD enumeration problem introduced by a recent commit adding ACPI support to the MFD subsystem that exposed a weakness in the ACPI core causing ACPI enumeration to be applied to all devices associated with one ACPI companion object, although it should be used for one of them only (Mika Westerberg). - Fix an ACPI EC regression introduced during the 3.17 cycle causing some Samsung laptops to misbehave as a result of a workaround targeted at some Acer machines. That includes a revert of a commit that went too far and a quirk for the Acer machines in question. From Lv Zheng. - Fix a regression in the system suspend error code path introduced during the 3.15 cycle that causes it to fail to take errors from asychronous execution of "late" suspend callbacks into account (Imre Deak). - Fix a long-standing bug in the hibernation resume error code path that fails to roll back everything correcty on "freeze" callback errors and leaves some devices in a "suspended" state causing more breakage to happen subsequently (Imre Deak). - Make the cpufreq-dt driver disable operation performance points that are not supported by the VR connected to the CPU voltage plane with acceptable tolerance instead of constantly failing voltage scaling later on (Lucas Stach)" * tag 'pm+acpi-3.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / EC: Fix regression due to conflicting firmware behavior between Samsung and Acer.

Pull PCI fixes from Bjorn Helgaas: "These changes, intended for v3.18, fix: Sysfs - Fix "enable" filename change (Greg Kroah-Hartman) An unintentional sysfs filename change in commit 5136b2da ("PCI: convert bus code to use dev_groups"), which appeared in v3.13, changed "enable" to "enabled", and this changes it back. Old users of "enable" are currently broken and will be helped by this change. Anything that started to use "enabled" after v3.13 will be broken by this change. If necessary, we can add a symlink to make both work, but this patch doesn't do that. PCI device hotplug - Revert duplicate merge (Kamal Mostafa) A mistaken duplicate merge that added a check twice. Nothing's broken; this just removes the unnecessary code.

Rusty noticed a Really Bad Bug (tm) in my NT fix. The entry code reads out of bounds, causing the NT fix to be unreliable. But, and this is much, much worse, if your stack is somehow just below the top of the direct map (or a hole), you read out of bounds and crash. Excerpt from the crash: [ 1.129513] RSP: 0018:ffff88001da4bf88 EFLAGS: 00010296 2b:* f7 84 24 90 00 00 00 testl $0x4000,0x90(%rsp) That read is deterministically above the top of the stack. I thought I even single-stepped through this code when I wrote it to check the offset, but I clearly screwed it up.

Pull networking fixes from David Miller: "A bit has accumulated, but it's been a week or so since my last batch of post-merge-window fixes, so... 1) Missing module license in netfilter reject module, from Pablo. Lots of people ran into this. 2) Off by one in mac80211 baserate calculation, from Karl Beldan. 3) Fix incorrect return value from ax88179_178a driver's set_mac_addr op, which broke use of it with bonding. From Ian Morgan. 4) Checking of skb_gso_segment()'s return value was not all encompassing, it can return an SKB pointer, a pointer error, or NULL. Fix from Florian Westphal. This is crummy, and longer term will be fixed to just return error pointers or a real SKB. 6) Encapsulation offloads not being handled by skb_gso_transport_seglen(). From Florian Westphal. 7) Fix deadlock in TIPC stack, from Ying Xue. 8) Fix performance regression from using rhashtable for netlink sockets. The problem was the synchronize_net() invoked for every socket destroy. From Thomas Graf. 9) Fix bug in eBPF verifier, and remove the strong dependency of BPF on NET. From Alexei Starovoitov. 10) In qdisc_create(), use the correct interface to allocate ->cpu_bstats, otherwise the u64_stats_sync member isn't initialized properly. From Sabrina Dubroca. 11) Off by one in ip_set_nfnl_get_byindex(), from Dan Carpenter. 12) nf_tables_newchain() was erroneously expecting error pointers from netdev_alloc_pcpu_stats(). It only returna a valid pointer or NULL. From Sabrina Dubroca. 13) Fix use-after-free in _decode_session6(), from Li RongQing. 14) When we set the TX flow hash on a socket, we mistakenly do so before we've nailed down the final source port. Move the setting deeper to fix this. From Sathya Perla. 15) NAPI budget accounting in amd-xgbe driver was counting descriptors instead of full packets, fix from Thomas Lendacky. 16) Fix total_data_buflen calculation in hyperv driver, from Haiyang Zhang. 17) Fix bcma driver build with OF_ADDRESS disabled, from Hauke Mehrtens. 18) Fix mis-use of per-cpu memory in TCP md5 code. The problem is that something that ends up being vmalloc memory can't be passed to the crypto hash routines via scatter-gather lists. From Eric Dumazet. 19) Fix regression in promiscuous mode enabling in cdc-ether, from Olivier Blin. 20) Bucket eviction and frag entry killing can race with eachother, causing an unlink of the object from the wrong list. Fix from Nikolay Aleksandrov. 21) Missing initialization of spinlock in cxgb4 driver, from Anish Bhatt. 22) Do not cache ipv4 routing failures, otherwise if the sysctl for forwarding is subsequently enabled this won't be seen.

Pull sparc update from David Miller: "Two changes: 1) It makes no sense to execute a VTOC partition table request in the Sun virtual block device driver and fail to load if it doesn't succeed because a) we don't use the result at all and b) it won't succeed if there is an EFI partition on the disk, for example.
