* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025

* Commit the 64-bit inode project.Konstantin Belousov2017-05-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the ino_t, dev_t, nlink_t types to 64-bit ints. Modify struct dirent layout to add d_off, increase the size of d_fileno to 64-bits, increase the size of d_namlen to 16-bits, and change the required alignment. Increase struct statfs f_mntfromname[] and f_mntonname[] array length MNAMELEN to 1024. ABI breakage is mitigated by providing compatibility using versioned symbols, ingenious use of the existing padding in structures, and by employing other tricks. Unfortunately, not everything can be fixed, especially outside the base system. For instance, third-party APIs which pass struct stat around are broken in backward and forward incompatible ways. Kinfo sysctl MIBs ABI is changed in backward-compatible way, but there is no general mechanism to handle other sysctl MIBS which return structures where the layout has changed. It was considered that the breakage is either in the management interfaces, where we usually allow ABI slip, or is not important. Struct xvnode changed layout, no compat shims are provided. For struct xtty, dev_t tty device member was reduced to uint32_t. It was decided that keeping ABI compat in this case is more useful than reporting 64-bit dev_t, for the sake of pstat. Update note: strictly follow the instructions in UPDATING. Build and install the new kernel with COMPAT_FREEBSD11 option enabled, then reboot, and only then install new world. Credits: The 64-bit inode project, also known as ino64, started life many years ago as a project by Gleb Kurtsou (gleb).

* Get rid of major/minor number distinction.Ed Schouten2011-09-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | As of FreeBSD 6, devices can only be opened through devfs. These device nodes don't have major and minor numbers anymore. The st_rdev field in struct stat is simply based a copy of st_ino. Simply display device numbers as hexadecimal, using "%#jx". This is allowed by POSIX, since it explicitly states things like the following (example taken from ls(1)): "If the file is a character special or block special file, the size of the file may be replaced with implementation-defined information associated with the device in question." This makes the output of these commands more compact. For example, ls(1) now uses approximately four columns less. While there, simplify the column length calculation from ls(1) by calling snprintf() with a NULL buffer. Don't be afraid; if needed one can still obtain individual major/minor numbers using stat(1).

* Serialize write() calls on TTYs.Ed Schouten2009-02-112-0/+10
| | | | | | | | | | | | | | | | | | | | | | | Just like the old TTY layer, the current MPSAFE TTY layer does not make any attempt to serialize calls of write(). Data is copied into the kernel in 256 (TTY_STACKBUF) byte chunks. If a write() call occurs at the same time, the data may interleave. This is especially likely when the TTY starts blocking, because the output queue reaches the high watermark. I've implemented this by adding a new flag, TTY_BUSY_OUT, which is used to mark a TTY as having a thread stuck in write(). Because I don't want non-blocking processes to be possibly blocked by a sleeping thread, I'm still allowing it to bypass the protection. According to this message, the Linux kernel returns EAGAIN in such cases, but I think that's a little too restrictive: http://kerneltrap.org/index.php?q=mailarchive/linux-kernel/2007/5/2/85418/thread PR: kern/118287 Notes: svn path=/head/; revision=188487
* Don't leave the console TTY constantly open.Ed Schouten2009-02-052-19/+22
| | | | | | | | | | | | | | | | | | | | When we leave the console TTY constantly open, we never reset the termios attributes. This causes output processing, echoing, etc. not to be reset to the proper values when going into single user mode after the system has booted. It also causes nl-to-crnl-conversion not to take place during shutdown, which causes a `staircase effect'. This patch adds a new TTY flag, TF_OPENED_CONS, which is set when the TTY is opened through /dev/console. Because the flags are only used by the kernel and the pstat(8) utility, I've decided to renumber the TTY flags. This shouldn't be an issue, because the TTY layer is not yet part of a stable release.

| | | | | | | | | | | We often run into these very high column numbers when we run curses applications, because they don't print any newlines. This messes up the table output of `pstat -t'.

* Introduce a hooks layer for the MPSAFE TTY layer.Ed Schouten2008-09-222-0/+3
| | | | | | | | | | | | | | | | | | | | | | | One of the features that prevented us from fixing some of the TTY consumers to work once again, was an interface that allowed consumers to do the following: - `Sniff' incoming data, which is used by the snp(4) driver. - Take direct control of the input and output paths of a TTY, which is used by ng_tty(4), ppp(4), sl(4), etc. There's no practical advantage in committing a hooks layer without having any consumers. In P4 there is a preliminary port of snp(4) and thompsa@ is busy porting ng_tty(4) to this interface. I already want to have it in the tree, because this may stimulate others to work on the remaining modules. Discussed with: thompsa Obtained from: //depot/projects/mpsafetty/...

* Integrate the new MPSAFE TTY layer to the FreeBSD operating system.Ed Schouten2008-08-202-163/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

* Remove OTTYDISC, NETLDISC and NTTYDISC definitions.Ed Schouten2008-07-161-4/+0
| | | | | | | | | | | | | | | | | | | When I ported most applications away from <sgtty.h>, I noticed none of them were actually using these definitions. I kept them in place, because I didn't want to touch tools like pstat(8) and stty(1). In preparation for the MPSAFE TTY layer, remove these definitions. This doesn't have any impact with respect to binary compatibility (see tty_conf.c). We couldn now add an #error to <sys/ioctl_compat.h> when included outside the kernel. Unfortunately, kdump's mkioctls includes this file unconditionally. Approved by: philip (mentor) Notes: svn path=/head/; revision=180559

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | setenv(3) by tracking the size of the memory allocated instead of using strlen() on the current value. Convert all calls to POSIX from historic BSD API: - unsetenv returns an int. - putenv takes a char * instead of const char *. - putenv no longer makes a copy of the input string. - errno is set appropriately for POSIX. Exceptions involve bad environ variable and internal initialization code. These both set errno to EFAULT. Several patches to base utilities to handle the POSIX changes from Andrey Chernov's previous commit. A few I re-wrote to use setenv() instead of putenv(). New regression module for tools/regression/environ to test these functions. It also can be used to test the performance. Bump __FreeBSD_version to 700050 due to API change.
