getgroups.2: Clarify, mention ascending order, add SECURITY CONSIDERATIONS

2025-10-10T17:15:58Z

Clarify and be more precise about the behavior of getgroups(2), in particular with respect to 'gidsetlen'. Prefer a terminology close to POSIX terms, i.e., use "effective groups" instead of "group access list". Say that getgroups(2) reports the supplementary groups in strictly ascending order (and mention this has been the case since FreeBSD 14.3). Add a new SECURITY CONSIDERATIONS section, in particular contrasting FreeBSD 15's behavior with the current one. While here, fix some style.

The original commit message above was reworked to reflect the actual commit content.

setgroups.2: Add SECURITY CONSIDERATIONS, rework

2025-10-10T17:15:58Z

Add a new SECURITY CONSIDERATIONS section contrasting the current behavior with the new one in force starting from FreeBSD 15. Prefer a terminology referring to POSIX terms, i.e., use "effective group list" instead of "group access list". While here, fix some style.

jail.2: Mention EPERM is returned on open directories

2025-10-10T17:15:55Z

The manual page does not directly mention this reason for getting EPERM, instead referring the reader to chroot(2). We have had some questions about it recently, in part due to a bug (fixed), and this case is not an obvious permission/problem, so let's be more explicit.
