MFC r357560, r357707: login.conf(5) mail capability

2020-02-12T02:04:03Z

r357560: login.conf(5): split MAIL env var out into a "mail" capability This allows it to be easily suppressed in, e.g., the "daemon" class where it will not be properly expanded. This is a part of D21481. Submitted by: Andrew Gierth r357707: login.conf(5): update commented-out standard, too MAIL now has a mail capability, instead, as of r357560.

r336746: Make pw_scan(3) more compatible with getpwent(3) et. al. when processing data from /etc/passwd rather than /etc/master.passwd. The libc getpwent(3) and related functions automatically read master.passwd when run by root, or passwd when run by a non-root user. When run by non- root, getpwent() copes with the missing data by setting the corresponding fields in the passwd struct to known values (zeroes for numbers, or a pointer to an empty string for literals). When libutil's pw_scan(3) was used to parse a line without the root-accessible data, it was leaving garbage in the corresponding fields. These changes rename the static pw_init() function used by getpwent() and friends to __pw_initpwd(), and move it into pw_scan.c so that common init code can be shared between libc and libutil. pw_scan(3) now calls __pw_initpwd() before __pw_scan(), just like the getpwent() family does, so that reading an arbitrary passwd file in either format and parsing it with pw_scan(3) returns the same results as getpwent(3) would. This also adds a new pw_initpwd(3) function to libutil, so that code which creates passwd structs from scratch in some manner that doesn't involve pw_scan() can initialize the struct to the values expected by lots of existing code, which doesn't expect to encounter NULL pointers or garbage values in some fields. r336779: Stop exporting __pw_scan and __pw_initpwd as freebsd-private libc functions for use in libutil, and instead compile the small amount of common code directly into libutil with a .PATH reachover.

r336017 This exposes ZFS user and group quotas via the normal quatactl(2) mechanism. (Read-only at this point, however.) In particular, this is to allow rpc.rquotad query quotas for NFS mounts, allowing users to see their quotas on the hosts using the datasets. The changes specifically: * Add new RPC entry points for querying quotas. * Changes the library routines to allow non-UFS quotas. * Changes rquotad to check for quotas on mounted filesystems, rather than being limited to entries in /etc/fstab * Lastly, adds a VFS entry-point for ZFS to query quotas. Note that this makes one unavoidable behavioural change: if quotas are enabled, then they can be queried, as opposed to the current method of checking for quotas being specified in fstab. (With ZFS, if there are user or group quotas, they're used, always.) r338799 Author: kib Fix ZFS VFS op quotactl to follow busy protocol. Approved by: mav Sponsored by: iXsystems, inc

humanize_number(3): fix math edge case in rounding large numbers Fix for remainder overflow, when in rare cases adding remainder to divider exceeded 1 and turned the total to 1000 in final formatting, taking up the space for the unit character. The fix continues the division of the original number if the above case happens -- added the appropriate check to the for loop performing the division. This lowers the value shown, to make it fit into the buffer space provided (1.0M for 4+1 character buffer, as used by ls). Add test case for the reported bug and extend test program to support providing buffer length (ls -lh uses 5, tests hard-coded 4). PR: 224498

This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)
