VFS_QUOTACTL(9): allow implementation to indicate busy state changes Instead of requiring all implementations of vfs_quotactl to unbusy the mount for Q_QUOTAON and Q_QUOTAOFF, add an "mp_busy" in/out param to VFS_QUOTACTL(9). The implementation may then indicate to the caller whether it needed to unbusy the mount. Also, add stbool.h to libprocstat modules which #define _KERNEL before including sys/mount.h. Otherwise they'll pull in sys/types.h before defining _KERNEL and therefore won't have the bool definition they need for mp_busy.

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 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.

This update uses the MNT_VNODE_FOREACH_ACTIVE interface that loops over just the active vnodes associated with a mount point to replace MNT_VNODE_FOREACH_ALL in the vfs_msync, ffs_sync_lazy, and qsync routines. The vfs_msync routine is run every 30 seconds for every writably mounted filesystem. It ensures that any files mmap'ed from the filesystem with modified pages have those pages queued to be written back to the file from which they are mapped. The ffs_lazy_sync and qsync routines are run every 30 seconds for every writably mounted UFS/FFS filesystem. The ffs_lazy_sync routine ensures that any files that have been accessed in the previous 30 seconds have had their access times queued for updating in the filesystem. The qsync routine ensures that any files with modified quotas have those quotas queued to be written back to their associated quota file. In a system configured with 250,000 vnodes, less than 1000 are typically active at any point in time. Prior to this change all 250,000 vnodes would be locked and inspected twice every minute by the syncer. For UFS/FFS filesystems they would be locked and inspected six times every minute (twice by each of these three routines since each of these routines does its own pass over the vnodes associated with a mount point). With this change the syncer now locks and inspects only the tiny set of vnodes that are active. Reviewed by: kib Tested by: Peter Holm MFC after: 2 weeks

Implement fine-grained locking for UFS quotas. Each struct dquot gets dq_lock mutex to protect dq_flags and to interlock with DQ_LOCK. qhash, dqfreelist and dq.dq_cnt are protected by global dqhlock mutex. i_dquot array for inode is protected by lockmgr' vnode lock, corresponding assert added to the dqget(). Access to struct ufsmount quota-related fields (um_quotas and um_qflags) is protected by um_lock.

Quota system cleanup. 1) Do not do quota accounting for the actual quota data files or for file system snapshot files ("system" files). This prevents a deadlock descibed in PR kern/30958 if the kernel ever has to grow the quota file. Snapshot files were already exempt from the quota checks, but this change generalized the check. 2) Fix a cast that caused extremely large uids/gids to incorrectly write the quota information to the data file at a truncated value for a uint_t32 id value. The incorrect cast caused quota files in this case to be around 4GB in size, with the correct cast they can now be 131GB in size. Also related to PR kern/30958. 3) Check for what appear to be negative UIDs/GIDs and not account for them. This prevents the quota files from becoming 131GB in size and causing quotacheck to run forever at bootup. This could also cause the kernel to try and expand the quota file, which might deadlock due to the issue in #1. kern/30958 and kern/38156 (and some much older closed PR's). 4) With the deadlock problems gone, the kernel can now expand the size of the quota database files if it needs to. 5) Pass in the i-node count change value to chkiq and chkiqchg as an int, like it used to be before the common routine was split up into 2 different routines to increase / decrease the i-node in-use count. Prevents an underflow on the i-node count. Related to PR kern/89247. 6) Prevent the block usage from growing slowly if a file system is full and the write was denied due to that fact. PR kern/89247. Some of these changes require an updated quotacheck to prevent the creation of huge (131GB) quota data files (item #3). #1/#4 probably fixes a lot of the random hangs when quotas are enabled, possibly some of the jail hangs.

Re-implement kernel access control for quotactl() as found in the UFS quota implementation. Push some quite broken access control logic out of ufs_quotactl() into the individual command implementations in ufs_quota.c; fix that logic. Pass in the thread argument to any quotactl command that will need to perform access control. o quotaon() requires privilege (PRISON_ROOT). o quotaoff() requires privilege (PRISON_ROOT). o getquota() requires that: If the type is USRQUOTA, either the effective uid match the requested quota ID, that the unprivileged_get_quota flag be set, or that the thread be privileged (PRISON_ROOT). If the type is GRPQUOTA, require that either the thread be a member of the group represented by the requested quota ID, that the unprivileged_get_quota flag be set, or that the thread be privileged (PRISON_ROOT). o setquota() requires privilege (PRISON_ROOT). o setuse() requires privilege (PRISON_ROOT). o qsync() requires no special privilege (consistent with what was present before, but probably not very useful). Add a new sysctl, security.bsd.unprivileged_get_quota, which when set to a non-zero value, will permit unprivileged users to query user quotas with non-matching uids and gids. Set this to 0 by default to be mostly consistent with the previous behavior (the same for USRQUOTA, but not for GRPQUOTA).

This commit adds basic support for the UFS2 filesystem. The UFS2 filesystem expands the inode to 256 bytes to make space for 64-bit block pointers. It also adds a file-creation time field, an ability to use jumbo blocks per inode to allow extent like pointer density, and space for extended attributes (up to twice the filesystem block size worth of attributes, e.g., on a 16K filesystem, there is space for 32K of attributes). UFS2 fully supports and runs existing UFS1 filesystems. New filesystems built using newfs can be built in either UFS1 or UFS2 format using the -O option. In this commit UFS1 is the default format, so if you want to build UFS2 format filesystems, you must specify -O 2. This default will be changed to UFS2 when UFS2 proves itself to be stable. In this commit the boot code for reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c) as there is insufficient space in the boot block. Once the size of the boot block is increased, this code can be defined. Things to note: the definition of SBSIZE has changed to SBLOCKSIZE. The header file <ufs/ufs/dinode.h> must be included before <ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and ufs_lbn_t. Still TODO: Verify that the first level bootstraps work for all the architectures. Convert the utility ffsinfo to understand UFS2 and test growfs. Add support for the extended attribute storage. Update soft updates to ensure integrity of extended attribute storage. Switch the current extended attribute interfaces to use the extended attribute storage. Add the extent like functionality (framework is there, but is currently never used). Sponsored by: DARPA & NAI Labs. Reviewed by: Poul-Henning Kamp <phk@freebsd.org>

The prerequisites for <ufs/ufs/quota.h> were broken in Lite2 by converting some of the kernel declarations to use queue macros without including <sys/queue.h>. <sys/queue.h> was included in applications in /usr/src instead. We polluted this file instead of merging the changes in the applications. Include <sys/queue.h> in the KERNEL case, and forward-declare all structs that are used in prototypes, so that this file is almost self-sufficient even in the kernel.
