46e47c8dcf Squashed commit of the following: 
drivers/serial/uart_16550.c:  Add a configuration, analogous to the STM32 configuration option, to suppress the NuttX standard re-ordering for /dev/ttySN for special case of the 16550 UART.

    config/serial: UART 16550: Add CONFIG_SERIAL_UART_ARCH_MMIO option so the a memory mapped device doesn't need to provide uart_getreg() and uart_putreg() implementations.

    u16550_txempty() should check UART_LSR_TEMT to avoid some data left in the transmit FIFO

drivers/serial:  Add Ctrl-C/Ctrl-X support.  This is an initial working implementation that still requires that several details be resolved.

    sched/task/task_start.c: Add default signal action to SIGKILL.

631071cded Squashed commit of the following: 
sched/wqueue:  Modify high priority work queue to support multiple threads.

    sched/wqueue and libs/libc/wqueue:  workqueues don't need set global data to zero since .bss is cleared automatically.  Removing this unnecessary initialization also avoids the loss the work items queued before initialization.

0074afa0ac net/netdev: add devif_loopback_out() to check the loopback case where a packet is being sent to itself. Modify the net driver to call this function in this case.

4a724b1f3c net/: Remove all references to CONFIG_NET_USER_DEVFMT. That feature is now unconditionally enabled. This was done because (1) the feature does not require very much additional memory, and (2) it causes confusion in the configuration due to the additional complexity. And network drivers that fail to zero the device structure interface name field (d_ifname) because calling netdev_register() will, however, get a nasty surprise. 2018-08-14 08:01:52 -06:00

4e5cf1229c drivers/mmcsd/Kconfig: three configuration settings were within ifdef/endif and led to warning: xxx selects xxxx which has unmet direct dependencies. Fix by moving settings to drivers/Kconfig and outside of the ifdef-endif.

20a86dfc1b binfmt/ and sched/group: Re-architect the way that loadable ELF or NXFLAT modules are unloaded. Memory resources must be recovered when the task loaded into memory exits. The originmal implementatino used the death-of-child SIGCHLD signal to perform the unload. There are several problems with this: It is overly complex, it requires that the parent task stay resident while the loaded task runs, and it has fatal logic flaws in the protected and kernel model builds because the user signal handler attempts to run in the kernel address space. This commit corrects with using a mindlessly simply BINFMT callback when the task exits. 2018-08-05 08:09:54 -06:00

056d704cf9 This commit brings in a fragmentary, experimental implementation of NETLINK sockets. There is not too much to that socket support on this initial commit, just the netlink socketer framework. However, I decided to bring it into master because there is a enough that I would not want to lose what is in place. And since it is dependent on CONFIG_EXPERIMENATL, its presence on master should be innocuous. 
Squashed commit of the following:

    net/netlink:  Mark netlink support as EXPERIMENTAL.
    net/netlink/netlink_sockif.c:  Add netlink_getpeername to the socket interface.
    net:  Add getpeeername() support for netlink sockets.
    include/netpacket/netlink.h:  Add a few more definitions and structures used at the NetLink interface.  Still missing many.
    net/netlink:  Add basic framework for Netlink socket support.
    include/:  Add basic Netlink definitions.

09ccd43d61 arch/arm/include/armv7-m, arch/arm/include/armv7-m, arch/arm/include/stm32f7: Add a configuration to enable workaround for r0p1 Errata 837070: Increasing priority usingwrite to BASEPRI does not take effect immediately. 
This update is required to be serialized to the instruction stream meaning that after this update completes, it takes effect immediately and no exceptions of lower priority than the new boosted priority can pre-empt execution.  Because of this erratum, the priority boosting does not take place immediately, allowing the instruction after the MSR to be interrupted by an exception of lower priority than the new boosted priority. This effect is only limited to the next instruction. Subsequent instructions are guaranteed to see the new boosted priority.

This was raised in Bitbucket issue 113 from Vadzim Dambrouski.

include/sys: Remove unused SYS_nnetsocket from syscall.h

Because SYS_nnetsocket is not implemented so far, it should be
removed so that SYS_prctl can work correctly.
