From: Yann Droneaud Date: Tue, 2 Jul 2013 16:39:36 +0000 (+0200) Subject: sctp: use get_unused_fd_flags(0) instead of get_unused_fd() X-Git-Tag: v3.11-rc1~64^2~31 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8a59bd3e9b296b93b905b5509c4ff540ee0e00bf;p=pandora-kernel.git sctp: use get_unused_fd_flags(0) instead of get_unused_fd() Macro get_unused_fd() is used to allocate a file descriptor with default flags. Those default flags (0) can be "unsafe": O_CLOEXEC must be used by default to not leak file descriptor across exec(). Instead of macro get_unused_fd(), functions anon_inode_getfd() or get_unused_fd_flags() should be used with flags given by userspace. If not possible, flags should be set to O_CLOEXEC to provide userspace with a default safe behavor. In a further patch, get_unused_fd() will be removed so that new code start using anon_inode_getfd() or get_unused_fd_flags() with correct flags. This patch replaces calls to get_unused_fd() with equivalent call to get_unused_fd_flags(0) to preserve current behavor for existing code. The hard coded flag value (0) should be reviewed on a per-subsystem basis, and, if possible, set to O_CLOEXEC. Signed-off-by: Yann Droneaud Acked-by: Vlad Yasevich Signed-off-by: David S.
