* libc/termios.c: Fixed a memory leak in the termios software. Basically the tty open function was allocating an input raw buffer, an output raw buffer, and a cooked buffer that were not getting released. I have attached a patch for the latest snapshot. The patch also has a fix to ensure the tty link list is updated correctly when a tty is closed.

* libc/printk.c (printNum): Properly handle a maxwidth of 0 as reported by Nick Hennenfent <NICK.HENNENFENT@ROCHE.COM>.

* libc/Makefile.am: Revamp INCLUDES handling to make automake-1.5 happy.

* libc/gxx_wrappers.c: Modifications to make gcc 3.x happy.

* include/rtems/libio_.h: Added ifdef to ensure that LOGIN_NAME_MAX is defined on GNU/Linux (RedHat 6.2 distribution). * libc/unixlibc.c: Added stubs for rtems_io_register_name() and rtems_io_lookup_name() so UNIX port would compile the IO manager sptest that registers /dev/null.

* libc/lseek.c: Modified after discussion with Eugeny S. Mints <jack@oktet.ru> to correct the behavior. There were two mistakes. First, iop->offset was incorrectly set for SEEK_END. Second, iop->offset should be left unmodified if there are errors. This modification attempts to fix both situations.

* libc/termios.c: Fix a bug in the termios implementation in the following scenario: The General Terminal Interface document that me states that if VMIN = 0 and VTIME = 0, then read() should return the minimum of two values: a) number of bytes available b) number of bytes requested (I assume from the read call) The current implementation of the fillBufferQueue() in termios.c is always return 1 character with these setting values. I know the termios buffer has more than one character available and my read() call is requesting 1024 bytes.

* libc/getgrent.c, libc/getpwent.c: the 'ls' and more related command previous failed after a chroot(). (unknown user & group)
2001-08-032001-08-03 Joel Sherrill <joel@OARcorp.com>Joel Sherrill1-0/+8
* libc/libio_sockets.c (rtems_bsdnet_fdToSocket): Per bug report from Gene Smith <Gene.Smith@sea.siemens.com>, enhanced the error checking to account for a socket being closed.
2001-05-252001-05-25 Joel Sherrill <joel@OARcorp.com>Joel Sherrill1-4/+2
* libc/base_fs.c: Deleted chmod() now that IMFS creates the root node with the desired permissions. chmod() is also not supported by the miniIMFS so this is not allowable.
2001-05-242000-05-24 Fernando Ruiz Casas <fernando.ruiz@ctv.es>Joel Sherrill3-9/+15
* libc/ttyname.c (ttyname_r): Removed duplicate call to closedir(). * libc/getpwent.c: Create a more robust /etc/passwd and /etc/group. * libc/base_fs.c: Change permissions of files and directories. Now uses octal constants.
2001-05-112001-05-11 Joel Sherrill <joel@OARcorp.com>Joel Sherrill1-1/+1
* libc/write.c: Change type of rc to match return type from underlying function per report from Eric Norum.
2001-04-242001-04-24 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-1/+2
* libc/libio.c (rtems_libio_allocate): Make sure size and offset fields are cleared on each file open. Before this field was cleared, this resulted in the value from the last time that IOP was used being still in place. Discovered by Andrew Bythell <abythell@nortelnetworks.com>. * libc/open.c: Remove redundant setting of iop->offset.

* include/rtems/libio_.h, libc/chroot.c, libc/privateenv.c: Private environment and chroot() enhancements and fixes. Comments: + privateenv has been modified to let at chroot() to be more POSIX like Sergei Organov recommended. + A task owner lets that rtems_set_private_env() will be called twice or more times. + chroot() can be called without a previous rtems_set_private_env(); (transpanrently) + The second call of rtems_set_private_env() makes a internal chroot("/") into global imfs_root. + chroot() runs like chdir() without a previous chdir("/") with the global root. + The current directory can be in a wrong place like Linux and many other Unices.

* libc/chroot.c: Fixed naming problems. Names were changed when the code this depends on was merged.

* 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.

2000-08-01Patch from Eric Norum <eric@cls.usask.ca> to avoid lockup underJoel Sherrill1-9/+9
the correct circumstances of DMA buffer size, serial line interrupts, and ethernet interrupts the termios osend routine would lock up waiting for the raw output buffer semaphore.
2000-07-26Port of RTEMS to the Texas Instruments C3x/C4x DSP families includingJoel Sherrill1-2/+2
a BSP (c4xsim) supporting the simulator included with gdb. This port was done by Joel Sherrill and Jennifer Averett of OAR Corporation. Also included with this port is a space/time optimization to eliminate FP context switch management on CPUs without hardware or software FP. An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8) on this CPU. This required addressing alignment checks and assumptions as well as fixing code that assumed sizeof(unsigned32) == 4.
