2ccc0da0c7 Move getopt() variables into TLS
getopt() in the FLAT build environment is not thread safe.  This is because global variables that are process-specific in Unix are truly global in the FLAT build.  Moving the getopt() variables into TLS resolves this issue.

No side-effects are expected other than to getopt()

Tested with sim:nsh

0b891d60f9 vfs: Define symlink as link
specified here:
https://pubs.opengroup.org/onlinepubs/009695399/functions/symlink.html
yes, symlink is different from link:
1.symlink create the soft(symbolic) link
2.link create the hard link
but it is suitable to make them same now since vfs doesn't support the
hard link and the soft link in file system level yet.

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

That part was correct before the PR. If CONFIG_ARCH_IDLE_CUSTOM, then the build should use a custom IDLE loop in the board src/ directory. 2018-05-11 06:26:01 -06:00

e4652bd3dc Squashed commit of the following:
fs: Add truncate() support for userfs
    fs/unionfs:  Add truncate() support to the unionfs
    fs/tmpfs:  Add ftruncate() support to tmpfs
    syscall/: Add system call support for ftruncate()
    net/route:  Adding ftruncate() support eliminates an issue in file-based routing table management.
    fs:  Add basic framework to support truncate() and ftruncate().  The infrastructure is complete.  Now, however, the actual implementation of ftruncate() will have to be done for each file system.

c23b7ec93d From Lorenz Meier: The implementation of access() as vararg macro has the issue that any function call with the same name (even in a C++ class) will match with it and result in a compile error. I have replaced it with a small function, and tried to have decent documentation as well. This resolves the compile issue, and shouldn’t have negative side effects for users of the function. 2014-11-11 11:52:24 -06:00
