* src/eventsurrender.c: Clear event condition when task is unblocked.
This makes sure that subsequent event send thinks the task is still
blocked and overwrites the initial events received.
* src/imfs/memfile.c: Reapply fix from bug report from
Jose Sturniolo <jsturnio@nec.com.ar> where NULL pointer
was dereferenced when freeing a triply indirect file.
The fix was applied to the 4.5 release branch and not
the development branch.
* cpu.c, cpu_asm.S, iregdef.h, rtems/score/cpu.h, rtems/score/mips.h:
Merged MIPS1 and MIPS3 code reducing the number of lines of assembly.
Also reimplemented some assembly routines in C further reducing
the amount of assembly and increasing maintainability.
* rtems_servers/ftp.d: Following changes:
- Hacks with current dir and root dir removed in favor of new libio
support for task-local current and root directories.
- Bug in `close_data_socket()' introduced by previous change fixed.
- `command_pasv()' changed to set timeout on socket we are listening
on and code fixed to don't close socket twice on error.
- `serr()' changed to clear `errno'.
- `data_socket()' changed to clear `errno' before `bind()'.
- `session()' changed to clear `errno' before processing session.
- `close_data_socket()' fixed to close both active and passive sockets
- Initialize info->data_socket to -1 in `daemon()'
- Initialize `fname' to empty string in `exec_command()'
* cpu.c, rtems/score/cpu.h: Bug report from Peter Mueller
<peter.o.mueller@gmx.de> because of not correcting for the ISR
vector table now being allocated from the workspace.
* lib/tftpDriver.c: Reduce first timeout interval. This
improves throughput on systems which are dropping packets.
Only the first timeout is reduced. This keeps the number
of extra packets down on networks that are very busy and
dropping lots of packets.
* cpu.c, rtems/score/cpu.h: Bug report from Peter Mueller
<peter.o.mueller@gmx.de> because of not correcting for the ISR
vector table now being allocated from the workspace.
* Alternate email is correo@fernando-ruiz.com
* libc/privateenv.c: New file.
* include/rtems/libio_.h, libc/Makefile.am, libc/base_fs.c,
libc/unmount.c: Moved default umask, current working directory,
root, and links followed count into a structure "user environment"
that can then be treated as a unit. This enable giving unique
copies of these to individual threads or collection of threads.
* rtems_servers/ftpd.c, rtems_servers/ftpd.h: Major enhancements
as listed below:
- Timeouts on sockets implemented. 'idle' field added to
configuration. No timeout by default to keep backward compatibility.
Note: SITE IDLE command not implemented yet.
- Basic global access control implemented. 'access' field added to
configuration. No access limitations by default to keep backward
compatibility.
- Anchor data socket for active mode (using self IP and port 20.)
- Fixed default data port support (still not tested).
- Don't allow IP address different from originating host in
PORT command to improve security.
- Fixed bug in MDTM command.
- Check for correctness of parsing of argument in command_port().
- Fixed squeeze_path() to don't allow names like 'NAME/smth' where
'NAME' is not a directory.
- Command parsing a little bit improved: command names are now
converted to upper-case to be more compatible with RFC (command
names are not case-sensitive.)
- Reformat comments so that they have RTEMS look-and-feel.
- Fixed DELE, SITE CHMOD, RMD, MKD broken by previous changes
- True ASCII mode implemented (doesn't work for hooks and /dev/null)
- Passive mode implemented, PASV command added.
- Default port for data connection could be used (untested, can't find
ftp client that doesn't send PORT command)
- SYST reply changed to UNIX, as former RTEMS isn't registered name.
- Reply codes reviewed and fixed.
* rtems_servers/ftpd.c, rtems_servers/ftpd.h: Major enhancements
as listed below:
- use pool of pre-created threads to handle sessions instead of
creating/deleting threads on the fly
- LIST output is now similar to what "/bin/ls -al" would output,
thus FTP clients such Netscape are happy with it.
- LIST NAME now works (both for files and directories)
- added support for NLST, CDUP, and MDTM FTP commands to make
more FTP clients happy
- keep track of CWD for every session separately
- ability to specify root directory name for FTPD in configuration
table. FTPD will then create illusion for FTP clients that this
is actually root directory.
- ignore options sent in commands, thus LIST -al FILE works and
doesn't try to list "-al" directory.
- buffers are allocated on stack instead of heap where possible to
eliminate malloc/free calls (avoid possible heap fragmentation
troubles).
- drop using of task notepad to pass parameters - use function
arguments instead
- use snprintf() instead of sprintf() as the latter is unsafe
- use of PF_INET in socket() instead of AF_INET
Here are ftp clients I've tried new FTPD with (all of them
running on Debian GNU/Linux 2.2):
Lftp 2.1.10
NcFTP 2.4.3
Netscape 4.75
ftp
mc 4.5.49
* src/imfs/imfs.h, src/imfs/imfs_creat.c, src/imfs/imfs_debug.c,
src/imfs/imfs_eval.c, src/imfs/imfs_fchmod.c,
src/imfs/imfs_handlers_memfile.c, src/imfs/imfs_init.c,
src/imfs/imfs_initsupp.c, src/imfs/imfs_stat.c, src/imfs/memfile.c,
src/imfs/miniimfs_init.c: Final developmental update to "tarfs".
When rtems_tarfs_load() is called, it checks the permissions
on each file. If there is write permission, it just creates a
standard file using "creat()" and therefore, uses the IMFS MEMORY_FILE.
If there is no write permission, it creates a LINEAR_FILE node
with the appropriate properties. If the permission is ever changed
to writeable, IMFS_fchmod converts it to a regular memory file.
* idtcpu.h: Commented out definition of "wait". It was stupid to
use such a common word as a macro.
* rtems/score/cpu.h (_CPU_ISR_Disable): Fixed for mips ISA 3.
* rtems/score/mips.h: Added include of <idtcpu.h>.
* rtems/score/mips.h (mips_enable_in_interrupt_mask): Corrected.
* devnull: New addition. Moved from libcpu/sh.
* devnull/devnull.c, devnull/devnull.h, devnull/.cvsignore,
devnull/Makefile.am: New files.
* Makefile.am, configure.in, wrapup/Makefile.am: Modified to reflect
addition of above.
* rtems/score/cpu.h: Added _CPU_Initialize_vectors().
* cpu_asm.S: Modify to properly dereference _ISR_Vector_table
now that it is dynamically allocated.
* rtems/score/cpu.h: Added _CPU_Initialize_vectors().
