| | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | file and processes information retrieval from the running kernel via sysctl in the form of new library, libprocstat. The library also supports KVM backend for analyzing memory crash dumps. Both procstat(1) and fstat(1) utilities have been modified to take advantage of the library (as the bonus point the fstat(1) utility no longer need superuser privileges to operate), and the procstat(1) utility is now able to display information from memory dumps as well. The newly introduced fuser(1) utility also uses this library and able to operate via sysctl and kvm backends. The library is by no means complete (e.g. KVM backend is missing vnode name resolution routines, and there're no manpages for the library itself) so I plan to improve it further. I'm commiting it so it will get wider exposure and review. We won't be able to MFC this work as it relies on changes in HEAD, which was introduced some time ago, that break kernel ABI. OTOH we may be able to merge the library with KVM backend if we really need it there. Discussed with: rwatson

* fstat: fix fsid comparison when executed on systems with 64-bit longavg2009-08-202-2/+2
| | | | | | | | | | | | | | | | | | | | | This affects only fstat on zfs and devfs, only on 64-bit systems and only when fsid is greater than 2^31 - 1. When fstat examines a file via stat(2) it takes uint32_t st_dev and assigns to (signed) (64-bit) long fsid, this results in a positive value. When fstat examines opened files it takes int32_t f_fsid.val[0] and assigns to (signed) (64-bit) long fsid, this results in a negative value. So, while initially st_dev and f_fsid.val[0] have the same bit values they get promoted to different 64-bit values because of the signed-vs-unsigned difference. A fix is to use "more natural" positive numbers by introducing intermediate unsigned cast for f_fsid.val[0]. Reviewed by: jhb, lulf Approved by: re (kib) MFC after: 1 week (to stable/7)

* Integrate the new MPSAFE TTY layer to the FreeBSD operating system.ed2008-08-201-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
