b7f958a02e binfmt/, binfmt/libelf: binfmt/elf: Call umm_initialize as soon as possible otherwise elf_loadctors/elf_loaddtors will fail to allocate memory. 2019-01-26 11:36:38 -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

bc2cded397 Squashed commit of the following: 
binfmt: Fix some compilation issues introduced in previous changes.  Verfied with the STM32F4-Discovery ELF configuration.

    binfmt:  schedule_unload() is an internal OS function and must not alter the errno variable.

    binfmt:  unload_module() is an internal OS function and must not alter the errno variable.

    binfmt:  load_module() is an internal OS function and must not alter the errno variable.

    binfmt:  exec_module() is an internal OS function and must not alter the errno variable.

835c91b03a Add support for a per-process virtual page allocator. This is a new member of the task_group_s structure. The allocaor must be initialized when a new user process is started and uninitialize when the process group is finally destroyed. It is used by shmat() and shmdt() to pick the virtual address onto which to map the shared physical memory. 2014-09-23 16:04:39 -06:00

398f7b594f execv() is a basic system interface. It should not be in libc/ but rather in sched/task. Its symboltable helper logic also belongs in the kernel but belings in binfmt/ with the other symbol table logic 2014-09-15 10:15:47 -06:00

df4682fd1f Add configuration to use the fixed DRAM mapping for the page pool (if available) instead of remapping dynamically to access L2 page tables and page data.

241a7e17bd addrenv interface changes: up_addrenv_create() may need to create .text and .bss/.data separately because of differing access privileges (read/execute vs read/write). And, as a consequence, up_addrenv_vaddr() needs to be split into up_addrenv_vtext(0 and up_addrenv_vdata(). 2014-08-24 11:54:14 -06:00
