c6adc4ba8e sched/pthread/pthread_initialize.c: Fix a warning found in build testing (that is actually and bug and would cause an incorrect value to be returned in many cases. 2018-08-05 16:23:07 -06:00

9726352d7a configs/olimex-stm32-p407/kmodule: Add a configuration that can be used for testing installation of kernel modules in the protected build. This configuration is useless in its present state, not due to any problem with the OS itself, but rather with the current apps/ build system. The symbol table is built by apps/examples/module/drivers/Makefile in user space. The problem with that is that the kernel module does reference internal kernel symbols which are not available in the user space build context. A mechanism is needed in the build system to build the symbol table in the context of the kernel. There is currently no way to do that. 2018-08-05 15:42:11 -06:00

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

5996d70883 Revise commit 09ccd43d61: That change had the subtle side-effect of unconditionally enabling interrupts in the primask. That may be what we want in most cases, but certainly not all. This does increse the size of the inline function by about 48-bits per instantiation. 2018-08-04 07:37:31 -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.

1d70e7f4b0 Revert "drivers/input/ft5x06.c: Back out part of last PR. I think that is correct to detach the interrupt handler when the drivers is unlinked." 
No... I was misled.  The shutdown function is usually called when the
driver is unlinked.  But not in this case.  In this case, it is simply
called when the last reference is closed.  And no, you don't want to
detach the interrupt handler in that case.  My bad.

This reverts commit b79e6b9c9a.

sched/mqueue/mq_notify.c: Fix - only part of struct copied to internal structure

As source adress the adress of the struct member sigev_value was used,
and it is not located the start of the struct.
This leads to invalid data being copied to internal structure.
Both source and destination should be of type struct sigevent* .
