Pull vfs open-related updates from Al Viro: - "do we need fput() or put_filp()" rules are gone - it's always fput() now. We keep track of that state where it belongs - in ->f_mode. - int *opened mess killed - in finish_open(), in ->atomic_open() instances and in fs/namei.c code around do_last()/lookup_open()/atomic_open(). - alloc_file() wrappers with saner calling conventions are introduced (alloc_file_clone() and alloc_file_pseudo()); callers converted, with much simplification. - while we are at it, saner calling conventions for path_init() and link_path_walk(), simplifying things inside fs/namei.c (both on open-related paths and elsewhere). * 'work.open3' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (40 commits) few more cleanups of link_path_walk() callers allow link_path_walk() to take ERR_PTR() make path_init() unconditionally paired with terminate_walk() document alloc_file() changes make alloc_file() static do_shmat(): grab shp->shm_file earlier, switch to alloc_file_clone() new helper: alloc_file_clone() create_pipe_files(): switch the first allocation to alloc_file_pseudo() anon_inode_getfile(): switch to alloc_file_pseudo() hugetlb_file_setup(): switch to alloc_file_pseudo() ocxlflash_getfile(): switch to alloc_file_pseudo() cxl_getfile(): switch to alloc_file_pseudo() ... and switch shmem_file_setup() to alloc_file_pseudo() __shmem_file_setup(): reorder allocations new wrapper: alloc_file_pseudo() kill FILE_{CREATED,OPENED} switch atomic_open() and lookup_open() to returning 0 in all success cases document ->atomic_open() changes ->atomic_open(): return 0 in all success cases get rid of 'opened' in path_openat() and the helpers downstream ...

Smack: Inform peer that IPv6 traffic has been blocked

2018-07-23T20:00:03Z

In this patch we're sending an ICMPv6 message to a peer to immediately inform it that making a connection is not possible. In case of TCP connections, without this change, the peer will be waiting until a connection timeout is exceeded. Signed-off-by: Piotr Sawicki Signed-off-by: Casey Schaufler

Smack: Check UDP-Lite and DCCP protocols during IPv6 handling

2018-07-23T19:59:51Z

The smack_socket_sock_rcv_skb() function is checking smack labels only for UDP and TCP frames carried in IPv6 packets. From now on, it is able also to handle UDP-Lite and DCCP protocols. Signed-off-by: Piotr Sawicki Signed-off-by: Casey Schaufler

Smack: Fix handling of IPv4 traffic received by PF_INET6 sockets

2018-07-23T19:59:41Z

A socket which has sk_family set to PF_INET6 is able to receive not only IPv6 but also IPv4 traffic (IPv4-mapped IPv6 addresses). Prior to this patch, the smk_skb_to_addr_ipv6() could have been called for socket buffers containing IPv4 packets, in result such traffic was allowed.

Smack: Mark inode instant in smack_task_to_inode

2018-06-23T01:45:56Z

Smack: Mark inode instant in smack_task_to_inode /proc clean-up in commit 1bbc55131e59bd099fdc568d3aa0b42634dbd188 resulted in smack_task_to_inode() being called before smack_d_instantiate. This resulted in the smk_inode value being ignored, even while present for files in /proc/self. Marking the inode as instant here fixes that.

Smack: Fix memory leak in smack_inode_getsecctx

2018-06-05T19:16:01Z

Fix memory leak in smack_inode_getsecctx The implementation of smack_inode_getsecctx() made incorrect assumptions about how Smack presents a security context. Smack does not need to allocate memory to support security contexts, so "releasing" a Smack context is a no-op. The code made an unnecessary copy and returned that as a context, which was never freed. The revised implementation returns the context correctly.

smack: provide socketpair callback

2018-05-04T19:48:54Z

Make sure to implement the new socketpair callback so the SO_PEERSEC call on socketpair(2)s will return correct information. Signed-off-by: Tom Gundersen Signed-off-by: David Herrmann Signed-off-by: James Morris
