51369649 - sys: further adoption of SPDX licensing ID tags.

Mon, 20 Nov 2017 19:43:44 +0000

sys: further adoption of SPDX licensing ID tags.Mainly focus on files that use BSD 3-Clause license.The Software Package Data Exchange (SPDX) group provides a specificationto make it easier for automated tools to detect and summarize well knownopensource licenses. We are gradually adopting the specification, notingthat 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 ofHighlander" tool: an older (2014) run over FreeBSD tree was useful as astarting point.

fbbd9655 - Renumber copyright clause 4

Tue, 28 Feb 2017 23:42:47 +0000

Renumber copyright clause 4Renumber cluase 4 to 3, per what everybody else did when BSD grantedthem permission to remove clause 3. My insistance on keeping the samenumbering for legal reasons is too pedantic, so give up on that point.Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96 List of files: /freebsd-12.1/sys/fs/cd9660/cd9660_node.h

c222ece0 - Mark cd9660 MPSAFE and add support for using shared vnode locks during

Wed, 28 Jan 2009 18:54:56 +0000

Mark cd9660 MPSAFE and add support for using shared vnode locks duringpathname lookups.- Remove 'i_offset' and 'i_ino' from the ISO node structure and replace them with local variables in the lookup routine instead.- Cache a copy of 'i_diroff' for use during a lookup in a local variable.- Save a copy of the found directory entry in a malloc'd buffer after a successfull lookup before getting the vnode. This allows us to release the buffer holding the directory block before calling vget() which otherwise resulted in a LOR between "bufwait" and the vnode lock.- Use an inlined version of vn_vget_ino() to handle races with .. lookups. I had to inline the code here since cd9660 uses an internal vget routine to save a disk I/O that would otherwise re-read the directory block.- Honor the requested locking flags during lookups to allow for shared locking.- Honor the requested locking flags passed to VFS_ROOT() and VFS_VGET() similar to UFS.- Don't make every ISO 9660 vnode hold a reference on the vnode of the underlying device vnode of the mountpoint. The mountpoint already holds a suitable reference. List of files: /freebsd-12.1/sys/fs/cd9660/cd9660_node.h

8d3027e2 - The ISO9660 spec does allow files up to 4G. Change the i_size

The ISO9660 spec does allow files up to 4G. Change the i_sizefield to "unsigned long" so that it actually works.Thanks to Robert Sciuk for sending me a DVD thatdemonstrated ISO9660-formatted media with a file >2G.I've now fixed this both in libarchive and in the cd9660filesystem.MFC after: 14 days List of files: /freebsd-12.1/sys/fs/cd9660/cd9660_node.h

a0595d02 - Add a flags parameter to VFS_VGET to pass through the desired

Sun, 17 Mar 2002 01:25:47 +0000

Add a flags parameter to VFS_VGET to pass through the desiredlocking flags when acquiring a vnode. The immediate purpose isto allow polling lock requests (LK_NOWAIT) needed by soft updatesto avoid deadlock when enlisting other processes to help withthe background cleanup. For the future it will allow the use ofshared locks for read access to vnodes. This change touches alot of files as it affects most filesystems within the system.It has been well tested on FFS, loopback, and CD-ROM filesystems.only lightly on the others, so if you find a problem there, pleaselet me (mckusick@mckusick.com) know.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"is an application space macro and the applications are supposed to be freeto use it as they please (but cannot).

bfbb9ce6 - Divorce "dev_t" from the "major|minor" bitmap, which is now called

Tue, 11 May 1999 19:55:07 +0000

Divorce "dev_t" from the "major|minor" bitmap, which is now calledudev_t in the kernel but still called dev_t in userland.Provide functions to manipulate both types: major() umajor() minor() uminor() makedev() umakedev() dev2udev() udev2dev()For now they're functions, they will become in-line functionsafter one of the next two steps in this process.Return major/minor/makedev to macro-hood for userland.Register a name in cdevsw[] for the "filedescriptor" driver.In the kernel the udev_t appears in places where we have themajor/minor number combination, (ie: a potential device: wemay not have the driver nor the device), like in inodes, vattr,cdevsw registration and so on, whereas the dev_t appears wherewe carry around a reference to a actual device.In the future the cdevsw and the aliased-from vnode will be hungdirectly from the dev_t, along with up to two softc pointers forthe device driver and a few houskeeping bits. This will essentiallyreplace the current "alias" check code (same buck, bigger bang).A little stunt has been provided to try to catch places where thewrong type is being used (dev_t vs udev_t), if you see somethingnot working, #undef DEVT_FASCIST in kern/kern_conf.c and see ifit makes a difference. If it does, please try to track it down(many hands make light work) or at least try to reproduce itas simply as possible, and describe how to do that.Without DEVT_FASCIST I belive this patch is a no-op.Stylistic/posixoid comments about the userland view of the files welcome now, from userland they now contain the end result.Next planned step: make all dev_t's refer to the same devsw[] whichmeans convert BLK's to CHR's at the perimeter of the vnodes andother places where they enter the game (bootdev, mknod, sysctl).
