da1a561b6e binfmt/libelf/libelf_bind.c: Make naming of internal type compliant with coding standard. Yes, the ELF32 types do not follow the standard for historical reasons (and will be fixed someday), but let's not perpetuate the naming violation. 2019-03-20 09:34:08 -06:00

ba859ad302 tools/nxstyle.c: Don't complain about certain lowercase characters in otherwise uppercase pre-processor identifers: IPv6, IPv4, ICMPv6, IGMPv2, p as a decimal point, d signifying a divisor.

ba8714daac binfmt/nxflat.c: Correct a double free debug assertion. This occurs when groups are enabled: (1) once via binfmt_exit and unload_module, and (2) once via sched_releasetcb(). this was corrected by adding logic to free/unload the memory once and nullify the pointer so that cannot be freed a second time.

a7fd58c4db Squashed commit of the following: 
many locations:  Change occurences of open() followed by file_detach() to file_open().  Change most non-controversion calls to open() to nx_open().

    fs/inode/fs_fileopen.c:  Flesh out file_open() with some interim, placeholder logic.

    fs/inode/fs_fileopen.c:  Add a framework for a file_open() implementation (no real logic in place yet).

    fs/vfs/fs_open.c:  Add nx_open() which is the same as open() except that it does not create a cancellation point nor does it modify the errno variable.

4becaea8e3 This commit extends support for the two-pass build. Its primary purpose is to incorporate source logic generated by applications into the kernel phase of the build. 
In the two pass build, the application logic is built during the first phase, pass 1.  In that phase, the application may generate and install source files in the pass1/directory.  The operating system is built during phase 2 of the build.  At that time, those source files in the pass1/ directory will be built and incorporated into the kernel address space.

The primary purpose of the pass1/ directory is to such application-generated kernel symbol tables.  For an example of the use of this feature, look at apps/examples/module/drivers/Makefile.  Kernel symbol tables are needed to support kernel modules.  Of course, addition board-specific logic in, say, configs/<board>/src would have to be included to make use of the application-installed symbol tables.

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

sched/sched:  Correct some build issues introduced by last set of changes.
    sched/sched:  Add new internal OS function nxsched_setaffinity() that is identical to sched_isetaffinity() except that it does not modify the errno value.  All usage of sched_setaffinity() within the OS is replaced with nxsched_setaffinity().
    sched/sched:  Internal functions sched_reprioritize() and sched_setpriority() no longer movidify the errno value.  Also renamed to nxsched_reprioritize() and sched_setpriority().
    sched/sched:  Add new internal OS function nxsched_getscheduler() that is identical to sched_getscheduler() except that it does not modify the errno value.  All usage of sched_getscheduler() within the OS is replaced with nxsched_getscheduler().
    sched/sched:  Add new internal OS function nxsched_setparam() that is identical to sched_setparam() except that it does not modify the errno value.  All usage of sched_setparam() within the OS is replaced with nxsched_setparam().
    sched/sched:  Add new internal OS function nxsched_getparam() that is identical to sched_getparam() except that it does not modify the errno value (actually, the previous value erroneously neglected to set the errno value to begin with, but this fixes both issues).  All usage of sched_getparam() within the OS is replaced with nxsched_getparam().

9568600ab1 Squashed commit of the following: 
This commit backs out most of commit b4747286b1.  That change was added because sem_wait() would sometimes cause cancellation points inappropriated.  But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.

    In the OS, all calls to sem_wait() changed to nxsem_wait().  nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.

    In all OS functions (not libraries), change sem_wait() to nxsem_wait().  This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.

    sched/semaphore:  Add the function nxsem_wait().  This is a new internal OS interface.  It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.

    libc/semaphore and sched/semaphore:  Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable.  Changed all references to sem_setprotocol in the OS to nxsem_setprotocol().  sem_getprotocol() was not used in the OS

    sched/semaphore:  Rename all internal private functions from sem_xyz to nxsem_xyz.  The sem_ prefix is (will be) reserved only for the application semaphore interfaces.

    libc/semaphore:  Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable.  Changed all references to sem_init in the OS to nxsem_init().

    sched/semaphore:  Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.

    sched/semaphoate:  Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.
