ec5120f69e sched/group and syscall/: Implement 'real' setuid, getuid, setgid, and getgid interfaces. These will be inheritance by all child task groups. 2019-08-06 14:13:43 -06:00

945e27d85c libs/libc/unistd.h: Add getuid() and getgid() to match Michael Jung's setuid() and setgid(). 2019-08-06 12:38:43 -06:00

e8af615578 libs/libc/unistd: Stubs for setuid and setgid. Added stubbed implementations of setuid and setgid. These functions are essentially stubs pretending that NuttX supported users and groups and that the only configured user and group in the system were both 'root' with a uid and a gid of 0, respectively. The intent is not to provide meaningful new features, but to ease porting of foreign source code to NuttX. 2019-08-06 07:17:23 -06:00

721994846c tools/: Change preferred argument of configurations tools to use ':' as the delimiter between <board-name> and <config-name>. This is to emphasize that this is not a path; it is configuration specification.
The legacy '/' delimiter is still supported but not recommend and not advertised.

Squashed commit of the following:

    Update configurations instructions in more README.txt files to show ':' delimiter vs '/' delimiter.
    Update configurations instructions in various README.txt file to show ':' delimiter vs '/' delimiter.
    tools:  Update all configuration-related tools to accept ':' separator between board and configuration name.

f3c85bd253 libc/pwd: Added stubbed implementations
Added stubbed implementations of getpwuid, getpwuid_r, getpwnam, and
getpwnam_r.  These functions are essentially stubs pretending that NuttX
supported users and that the only configured user in the system was 'root'
with uid 0.  The intend is not to provide meaningful new features, but to ease
porting of foreign source code to NuttX.

2fcff93d20 libs/libc/grp/lib_grp.c: Fix a warning when compiling on a 64-bit simulation. Cannot cast a pointer to unsigned in that case because unsigned (int) is only 32-bits, but the pointer is 64-bits. 2019-08-03 08:41:55 -06:00
Michael Jung
1af4c94391 libc/grp: Added stubbed implementations of getgrgid, getgrgid_r, getgrnam, getgrnam_r, and initgroups.

ded8711261 libs/libc/dirent/: Added alphasort, scandir and DT_* defines
- Added an alphasort implementation
- Added a scandir implementation
- Added DT_* literals to include/dirent.h: Apparently those are not required by POSIX, but are part of 4.3BSD and available in glibc as well.

libs/libc/misc/Make.defs:  For platforms whose CPP tool does not support a variable number arguments to pre-processor macros, we may still need to build the debug functions even when CONFIG_DEBUG_FEATURES is not selected.  For example, __alert() may be needed is CONFIG_ARCH_STACKDUMP is set.

Squashed commit of the following:

    configs/makerlisp:  Add LED support, remove vestiges of button support (the board has no user buttons).  Add support for SPI-based MMC/SD card slot.

    arch/z80/src/ez80:  Fix some link problems.

    libs/libc/syslog/lib_syslog.c:  The ZDS-II toolchain does not declare va_coy in stdarg.h.  I think that the use of va_copy in vsyslog() is no necessary.

    configs/makerlisp:  Initial configuration directories cloned from ez80f910200zco with little more than naming changes.

libs/libc/pthread/pthread_spinlock.c:  Resolve several TODO issues by accessing up_testset() via the boardctl() interface rather than attempting to call it directly.

    configs/boardctl.c, include/sys/boardctl.h:  Add access to architecture-specific up_testset() via boardctl().

    arch/Kconfig's, sched/Kconfig, and include/nuttx/spinlock.h:  Spinlocks are not available unless the architecture supports the up_testset() operation.

dc8c814ca3 Squashed commit of the following:
Fixed coding standard error in several files.  Use of while( is incorrect; a space is required between while and (.  Also ran tools/nxstyle and fix thoses complaints as well in most files.

    Changes to comply with coding standard.  Mostly focused on files with missing space after keyword in if(, switch(, and for(.  Offending files also got changes to comply with tools nxstyle.  If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh.  Still need to fix occurrences of while( with missing space.  There are a lot of them.

0951151c33 libs/libc/pthread, syscall/, and include/sys/syscall.h: Support for pthread_mutex_timedlock() was added recently, however no new system call was added for the API make is usable only in the FLAT build. With a pthread_mutex_timedlock() system call, there is no reason for a pthread_mutex_lock() system call since it is now nothing more than an wrapper around pthread_mutex_timedlock(), passing NULL for the time value. The pthread_mutex_lock() syscall was removed and the pthread_mutex_lock() implemented was moved from /sched/pthread to where it now belows in libs/libc/pthread. 2019-02-25 18:19:13 -06:00

0059a5a88e libs/libc/stdio/lib_vsprintf.c and Kconfig:
- Numbered arguments now work by using two pass parsing and an argument list.
    The maximum number of numbered args is determined by CONFIG_LIBC_NL_ARGMAX
    which is then copied into NL_ARGMAX.
  - Size of pointer argument ('p') is determined before output.

  values' per http://pubs.opengroup.org/onlinepubs/7908799/xsh/limits.h.html)

76a2f6c2a2 libs/libc/stdio: This commits makes the nano-printf the defualt logic for the printf family. The legacy printf is still available via CONFIG_LIBC_PRINT_LEGACY. This commit also modifies the nano-prinf configure: The PRINT_LEVEL is not long selectable.

38e93ede2b Revert "libs/libc/stdio: Fix the %f floating point output format."
The previous implementation was probably corect.  On Cygwin with GCC I see this:

int main(int argc, char **argv)
{
  printf("Value 1.2 is: [%f]\n", 1.2);
  printf("Value 0.1 is: [%f]\n", 0.1);
  printf("Value 0.0: [%f]\n", 0.0);
  printf("Value 347.6872: [%f]\n", 347.6872);
}

Generates output

Value 1.2 is: [1.200000]
Value 0.1 is: [0.100000]
Value 0.0: [0.000000]
Value 347.6872: [347.687200]

This reverts commit eb0223bc7f.

350295d009 Squashed commit of the following:
Author: Gregory Nutt <gnutt@nuttx.org>

    TODO:  Remove 'Missing fscanf()' bug
    Clean up remaining complaints for tools/nxstyle
    Apply tools/detab, rmcr, convert-comments, lowhex, and indent.sh to the new and highly modified files.

Author: Johannes <nivus.entwicklung@gmail.com>

    - Move vscanf logic to lib_sscanf.c  Switched to stream interface (tricky, because the old implementation used massive read ahead, which isn't suitable for streams, chars already read are gone).
    - Added scanf and fscanf
    - Added hh, h, and ll modifiers
    - Fixes for standard compliance in scanf
    - Fixes for standard compliance in strto... function family (don't consume single '-' or '+', allow sign in strotul(l))

e05149b745 libs/libc/stdio: Add newlib-nano fprintf as an option. This fprintf code was originally adapted from AVR libc and provides improved floating point output support, including 'g' mode and making 'f' mode include digits past the decimal by default. However, this version does not have any long long support. On a demonstration cortex M4 build, this version saves about 5kB of ROM. The newlib version can be found here: https://salsa.debian.org/electronics-team/toolchains/newlib-nano . That project is GPL overall, but the newlib-nano printf portions are BSD licensed as described in the COPYING.NEWLIB file. 2019-02-06 15:50:52 -06:00
