From 5889aa978ddc93d31d3c48c29899761ebde3f53d Mon Sep 17 00:00:00 2001 From: =?utf8?q?G=C3=BCnther=20Noack?= Date: Fri, 2 May 2025 12:24:03 +0200 Subject: [PATCH] man/man2const/TIOCLINUX.2const: Document CAP_SYS_ADMIN requirement for TIOCL_SETSEL modes MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit CAP_SYS_ADMIN was previously required for the entire TIOCL_SETSEL subcode, but is now only needed for a subset of the selection modes, since linux.git 2f83e38a095f (2025-01-13; "tty: Permit some TIOCL_SETSEL modes without CAP_SYS_ADMIN"). The CAP_SYS_ADMIN requirement for TIOCL_SELMOUSEREPORT was further corrected in linux.git ee6a44da3c87 (2025-04-11; "tty: Require CAP_SYS_ADMIN for all usages of TIOCL_SELMOUSEREPORT"). Admittedly, there are kernels where CAP_SYS_ADMIN was briefly not required for TIOCL_SELMOUSEREPORT, even after Linux v6.7, but this was a mistake which is now fixed in all up-to-date stable kernels. Therefore, we still document CAP_SYS_ADMIN as required "since Linux 6.7" in this case.
