Use the UID and GID of the executing user for the real and effective UID
and GID of the shell task in case no login check is present. This
prevents privilege escalation via shell scripts.
Use '*" to disable shell login instead of '!' according to the Linux man
page. Use getpwnam_r() instead of getpwnam(). Do not access the user
environment directly. Update the user environment only after a
successful login check.
This is a small (21K on sparc) editor that provides some powerful
features useful when a file needs editing on an embedded
board. No need to copy files off, edit, copy back.
The ping code is taken from a recent FreeBSD release. Some options have been
tested, other not tested or do not work. This could be due to the age of
our TCP/IP stack.
This version of ping will not work if more than 64 file descriptors are
open at once because the select FD size is 64 as set in newlib.
Remove rtems_current_shell_env as this is dangerous because
the env can be NULL if used outside of a valid shell with the
POSIX key to an env set up.
Clean up the usage of rtems_current_shell_env.
Use posix keys for current shell environment instead of task variables. With
this patch the shell needs one posix-key and one posix-key-value-pair
configured.
Update documentation for the shell.
Adapt samples/fileio:
- Add necessary objects.
- Add login function and custom device name for better testing of the shell.
Control the help command break with the SHELL_LINES evironment variable
where the numeric value is the number of lines to break on. If the
value is 0 the output is not broken. The default is 16 lines.
Add shell documentation for the help command.
In case the length of cwd path plus the userScriptName exceeds
PATH_MAX (255), the strncat calls will overflow scriptFile. Also
check for getcwd failure.
Move implementation specific parts of message.h and message.inl into new
header file messageimpl.h. The message.h contains now only the
application visible API.
