6a3c2aded6 Fix wait loop and void cast (#24) 
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

4ae09a3b80 net/netlink: Redesign the logic that handles notifications of when response data is available. Signal handlers are sub-optimal inside the OS (especially after the preceding change which forces the hand). Instead, use the work queue notifiers as is done with all other network notifiers. 2019-11-28 14:20:40 -06:00

69318b1024 Re-implements reverted commit 344f7bc9f6 in a way that should not have the undesired side-effect. include/nuttx/sched.h: Add a bit to the TCB flags to indicat the thread is a user thread in a syscall. sched/nuttx/nxsig_dispatch.c: Delay dispatching to signal handlers if within a system call. In all syscall implementations: Process delayed signal handling when exiting system call. 2019-11-28 12:47:36 -06:00

cbdd590c82 Revert "include/nuttx/sched.h: Add storage for a previous signal mask. arch/: In all syscall implementations, block all signals before dispatching a system call; resotre signal mask when the system call returns." 
Using the sigprocmask() for this purpose has too many side-effects.

This reverts commit 344f7bc9f6.

93ed8b66d9 net/netlink: Add partial support for the NETLINK poll() operation. Still missing is some signal handling logic that actually wakes up the poll() when an asynchronous NETLLINK response is available. 
So although the poll() implemenation is still not yet usable, the commit is useful because it (1) does not harm, and (2) incidentally fixes a few other issues in the NETLONK response queuing that I noted in the process.

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.
