e6050b6 iscsi_ibft: filter null v4-mapped v6 addresses I've had reports of UEFI platforms failing iSCSI boot in various configurations, that ended up being caused by network initialization scripts getting tripped up by unexpected null addresses (0.0.0.0) being reported for gateways, dhcp servers, and dns servers. The tianocore EDK2 iSCSI driver generates an iBFT table that always uses IPv4-mapped IPv6 addresses for the NIC structure fields. This results in values that are "not present or not specified" being reported as ::ffff:0.0.0.0 rather than all zeros as specified. The iscsi_ibft module filters unspecified fields from the iBFT from sysfs, preventing userspace from using invalid values and making it easy to check for the presence of a value. This currently fails in regard to these mapped null addresses. In order to remain consistent with how the iBFT information is exposed, we should accommodate the behavior of the tianocore iSCSI driver as it's already in the wild in a large number of servers. Tested under qemu using an OVMF build of tianocore EDK2.

38d8571 drm: fix writing to /sys/class/drm/*/status Writing to a file is supposed to return the number of bytes written. Returning zero unfortunately causes bash to constantly spin trying to write to the sysfs file, to such an extent that even ^c and ^z have no effect. The only way out of that is to kill the shell and log back in. This isn't nice behaviour. Fix it by returning the number of characters written to sysfs files.

088df2c Input: alps - do not reduce trackpoint speed by half On some v7 devices (e.g. Lenovo-E550) the deltas reported are typically only in the 0-1 range dividing this by 2 results in a range of 0-0. And even for v7 devices where this does not lead to making the trackstick entirely unusable, it makes it twice as slow as before we added v7 support and were using the ps/2 mouse emulation of the dual point setup. If some kind of generic slowdown is actually necessary for some devices, then that belongs in userspace, not in the kernel.

9b7b819 compat: cleanup coding in compat_get_bitmap() and compat_put_bitmap() In the functions compat_get_bitmap() and compat_put_bitmap() the variable nr_compat_longs stores how many compat_ulong_t words should be copied in a loop. The copy loop itself is this: if (nr_compat_longs-- > 0) { if (__get_user(um, umask)) return -EFAULT; } else { um = 0; } Since nr_compat_longs gets unconditionally decremented in each loop and since it's type is unsigned this could theoretically lead to out of bounds accesses to userspace if nr_compat_longs wraps around to (unsigned)(-1). Although the callers currently do not trigger out-of-bounds accesses, we should better implement the loop in a safe way to completely avoid such warp-arounds.

425be56 x86/asm/irq: Stop relying on magic JMP behavior for early_idt_handlers The early_idt_handlers asm code generates an array of entry points spaced nine bytes apart. It's not really clear from that code or from the places that reference it what's going on, and the code only works in the first place because GAS never generates two-byte JMP instructions when jumping to global labels. Clean up the code to generate the correct array stride (member size) explicitly. This should be considerably more robust against screw-ups, as GAS will warn if a .fill directive has a negative count. Using '. =' to advance would have been even more robust (it would generate an actual error if it tried to move backwards), but it would pad with nulls, confusing anyone who tries to disassemble the code. The new scheme should be much clearer to future readers. While we're at it, improve the comments and rename the array and common code. Binutils may start relaxing jumps to non-weak labels. If so, this change will fix our build, and we may need to backport this change.

31a4189 xen: netback: read hotplug script once at start of day. When we come to tear things down in netback_remove() and generate the uevent it is possible that the xenstore directory has already been removed (details below). In such cases netback_uevent() won't be able to read the hotplug script and will write a xenstore error node. A recent change to the hypervisor exposed this race such that we now sometimes lose it (where apparently we didn't ever before). Instead read the hotplug script configuration during setup and use it for the lifetime of the backend device. The apparently more obvious fix of moving the transition to state=Closed in netback_remove() to after the uevent does not work because it is possible that we are already in state=Closed (in reaction to the guest having disconnected as it shutdown). Being already in Closed means the toolstack is at liberty to start tearing down the xenstore directories. In principal it might be possible to arrange to unregister the device sooner (e.g on transition to Closing) such that xenstore would still be there but this state machine is fragile and prone to anger... A modern Xen system only relies on the hotplug uevent for driver domains, when the backend is in the same domain as the toolstack it will run the necessary setup/teardown directly in the correct sequence wrt xenstore changes.

This actually wasn't happening due to a short-circuit that only checked the DP_AUX_CH_CTL_DONE bit in status rather than checking that the operation was done and that DP_AUX_CH_CTL_TIME_OUT_ERROR was not set. [v2] Implemented alternate solution suggested by Jani Nikula.

494e5b6 sparc: Resolve conflict between sparc v9 and M7 on usage of bit 9 of TTE sparc: Resolve conflict between sparc v9 and M7 on usage of bit 9 of TTE Bit 9 of TTE is CV (Cacheable in V-cache) on sparc v9 processor while the same bit 9 is MCDE (Memory Corruption Detection Enable) on M7 processor. This creates a conflicting usage of the same bit. Kernel sets TTE.cv bit on all pages for sun4v architecture which works well for sparc v9 but enables memory corruption detection on M7 processor which is not the intent. This patch adds code to determine if kernel is running on M7 processor and takes steps to not enable memory corruption detection in TTE erroneously.

2459534 net: dsa: Properly propagate errors from dsa_switch_setup_one While shuffling some code around, dsa_switch_setup_one() was introduced, and it was modified to return either an error code using ERR_PTR() or a NULL pointer when running out of memory or failing to setup a switch. This is a problem for its caler: dsa_switch_setup() which uses IS_ERR() and expects to find an error code, not a NULL pointer, so we still try to proceed with dsa_switch_setup() and operate on invalid memory addresses. This can be easily reproduced by having e.g: the bcm_sf2 driver built-in, but having no such switch, such that drv->setup will fail. Fix this by using PTR_ERR() consistently which is both more informative and avoids for the caller to use IS_ERR_OR_NULL().

9f95041 tcp: fix child sockets to use system default congestion control if not set Linux 3.17 and earlier are explicitly engineered so that if the app doesn't specifically request a CC module on a listener before the SYN arrives, then the child gets the system default CC when the connection is established. See tcp_init_congestion_control() in 3.17 or earlier, which says "if no choice made yet assign the current value set as default". The change ("net: tcp: assign tcp cong_ops when tcp sk is created") altered these semantics, so that children got their parent listener's congestion control even if the system default had changed after the listener was created. This commit returns to those original semantics from 3.17 and earlier, since they are the original semantics from 2007 in 4d4d3d1e8 ("[TCP]: Congestion control initialization."), and some Linux congestion control workflows depend on that. In summary, if a listener socket specifically sets TCP_CONGESTION to "x", or the route locks the CC module to "x", then the child gets "x". Otherwise the child gets current system default from net.ipv4.tcp_congestion_control. That's the behavior in 3.17 and earlier, and this commit restores that.

beb39db udp: fix behavior of wrong checksums We have two problems in UDP stack related to bogus checksums : 1) We return -EAGAIN to application even if receive queue is not empty. This breaks applications using edge trigger epoll() 2) Under UDP flood, we can loop forever without yielding to other processes, potentially hanging the host, especially on non SMP. This patch is an attempt to make things better. We might in the future add extra support for rt applications wanting to better control time spent doing a recv() in a hostile environment. For example we could validate checksums before queuing packets in socket receive queue.

9809889 serial: 8250_omap: provide complete custom startup & shutdown callbacks The currently in-use port->startup and port->shutdown are "okay". The startup part for instance does the tiny omap extra part and invokes serial8250_do_startup() for the remaining pieces. The workflow in serial8250_do_startup() is okay except for the part where UART_RX is read without a check if there is something to read. I tried to workaround it in commit 0aa525d11859 ("tty: serial: 8250_core: read only RX if there is something in the FIFO") but then reverted it later in commit ca8bb4aefb9 ("serial: 8250: Revert "tty: serial: 8250_core: read only RX if there is something in the FIFO""). This is the second attempt to get it to work on older OMAPs without breaking other chips this time Peter Hurley suggested to pull in the few needed lines from serial8250_do_startup() and drop everything else that is not required including making it simpler like using just request_irq() instead the chain handler like it is doing now.
