jeff 2007-12-30 01:42:15 UTC FreeBSD src repository Modified files: sys/compat/svr4 svr4_stream.c sys/dev/streams streams.c sys/fs/devfs devfs_vnops.c sys/fs/fifofs fifo_vnops.c sys/kern kern_descrip.c kern_event.c sys_generic.c sys_pipe.c uipc_mqueue.c uipc_syscalls.c uipc_usrreq.c vfs_syscalls.c vfs_vnops.c sys/netgraph ng_socket.c sys/opencrypto cryptodev.c sys/sys file.h unpcb.h Log: Remove explicit locking of struct file. - Introduce a finit() which is used to initailize the fields of struct file in such a way that the ops vector is only valid after the data, type, and flags are valid. - Protect f_flag and f_count with atomic operations. - Remove the global list of all files and associated accounting. - Rewrite the unp garbage collection such that it no longer requires the global list of all files and instead uses a list of all unp sockets. - Mark sockets in the accept queue so we don't incorrectly gc them.
