https://git.reactos.org/?p=reactos.git;a=commitdiff;h=632fa1cfbe32dbcc1f97d… commit 632fa1cfbe32dbcc1f97dc96c9d6374cacf94ac7 Author: George Bișoc <george.bisoc(a)reactos.org> AuthorDate: Sun Jul 25 11:37:02 2021 +0200 Commit: George Bișoc <george.bisoc(a)reactos.org> CommitDate: Sat Jul 31 17:23:05 2021 +0200 [NTOS:SE] Handle the reference logon session of the token When creating or duplicating an access token object, make sure that the logon session is getting referenced by the token must be inserted onto the logon reference member (a.k.a LogonSession) for proper logon session referencing tracking. Also when a token object is about to be destroyed or that we are taking away a reference session from it, we must ensure that the referenced logon session data gets removed from the token in question.

Originally imported at 3a3ef631d12d8ac7ee2a95abf8c1c6e4815ac1a5 The driver is written by Lee Jae-Hong, updated by Bo Brantén. ReactOS porting made by Peter Hater and Pierre Schweitzer. Follow updates at http://www.acc.umu.se/~bosse/ FS Recognizer code is left to keep the FS support as an installable driver.

The super-block is critical - * data and is replicated in each cylinder group to protect against - * catastrophic loss. This is done at `newfs' time and the critical - * super-block data does not change, so the copies need not be - * referenced further unless disaster strikes. - * - * For file system fs, the offsets of the various blocks of interest - * are given in the super block as: - * [fs->fs_sblkno] Super-block - * [fs->fs_cblkno] Cylinder group block - * [fs->fs_iblkno] Inode blocks - * [fs->fs_dblkno] Data blocks - * The beginning of cylinder group cg in fs, is given by - * the ``cgbase(fs, cg)'' macro. - * - * Depending on the architecture and the media, the superblock may - * reside in any one of four places. For tiny media where every block - * counts, it is placed at the very front of the partition. Historically, - * UFS1 placed it 8K from the front to leave room for the disk label and - * a small bootstrap. For UFS2 it got moved to 64K from the front to leave - * room for the disk label and a bigger bootstrap, and for really piggy - * systems we check at 256K from the front if the first three fail. In - * all cases the size of the superblock will be SBLOCKSIZE. All values are - * given in byte-offset form, so they do not imply a sector size. The - * SBLOCKSEARCH specifies the order in which the locations should be searched. - * - * Unfortunately the UFS2/FFSv2 change was done without adequate consideration - * of backward compatibility. In particular 'newfs' for a FFSv2 partition - * must overwrite any old FFSv1 superblock at 8k, and preferrably as many - * of the alternates as it can find - otherwise attempting to mount on a - * system that only supports FFSv1 is likely to succeed!. - * For a small FFSv1 filesystem, an old FFSv2 superblock can be left on - * the disk, and a system that tries to find an FFSv2 filesystem in preference - * to and FFSv1 one (as NetBSD does) can mount the old FFSv2 filesystem. - * As a added bonus, the 'first alternate' superblock of a FFSv1 filesystem - * with 64k blocks is at 64k - just where the code looks first when playing - * 'hunt the superblock'. - * - * The ffsv2 superblock layout (which might contain an ffsv1 filesystem) - * can be detected by checking for sb->fs_old_flags & FS_FLAGS_UPDATED. - * This is the default suberblock type for NetBSD since ffsv2 support was added. - */ -#define BBSIZE 8192 -#define BBOFF ((off_t)(0)) -#define BBLOCK ((daddr_t)(0)) - -#define SBLOCK_FLOPPY 0 -#define SBLOCK_UFS1 8192 -#define SBLOCK_UFS2 65536 -#define SBLOCK_PIGGY 262144 -#define SBLOCKSIZE 8192 -/* - * NB: Do not, under any circumstances, look for an ffsv1 filesystem at - * SBLOCK_UFS2.

https://git.reactos.org/?p=reactos.git;a=commitdiff;h=2e2190df57adf5bfbd47d… commit 2e2190df57adf5bfbd47d99ee88b01579eecd940 Author: Victor Perevertkin <victor.perevertkin(a)reactos.org> AuthorDate: Fri Jul 23 21:12:31 2021 +0300 Commit: Victor Perevertkin <victor.perevertkin(a)reactos.org> CommitDate: Fri Jul 30 17:14:53 2021 +0300 [REISERFS] Remove the ReiserFS driver The upstream driver is not maintained and the file system itself is in a semi-abandoned state. Originally imported at e308102f4ab47c3c6a9107c743cbf3ec2c38f690 The driver is written by Mark W Piper, updated by Bo Brantén. ReactOS porting made by Peter Hater and Pierre Schweitzer. Follow updates at http://www.acc.umu.se/~bosse/ FS Recognizer code is left to keep the FS support as an installable driver.
