tcp: Remove timewait_sock_ops.twsk_destructor().

2025-08-26T00:53:35+00:00

Since DCCP has been removed, sk->sk_prot->twsk_prot->twsk_destructor is always tcp_twsk_destructor(). Let's call tcp_twsk_destructor() directly in inet_twsk_free() and remove ->twsk_destructor(). While at it, tcp_twsk_destructor() is un-exported.

tcp: get rid of twsk_unique()

2024-05-10T03:25:55+00:00

DCCP is going away soon, and had no twsk_unique() method. We can directly call tcp_twsk_unique() for TCP sockets. Signed-off-by: Eric Dumazet Reviewed-by: Kuniyuki Iwashima Link: https://lore.kernel.org/r/20240507164140.940547-1-edumazet@google.com Signed-off-by: Jakub Kicinski

[PATCH] tcp: Cache inetpeer in timewait socket, and only when necessary.

2012-06-09T21:56:12+00:00

Since it's guarenteed that we will access the inetpeer if we're trying to do timewait recycling and TCP options were enabled on the connection, just cache the peer in the timewait socket. In the future, inetpeer lookups will be context dependent (per routing realm), and this helps facilitate that as well. Signed-off-by: David S. Miller

BUG: headers with BUG/BUG_ON etc. need linux/bug.h

2012-03-04T22:54:34+00:00

If a header file is making use of BUG, BUG_ON, BUILD_BUG_ON, or any other BUG variant in a static inline (i.e. not in a #define) then that header really should be including and not just expecting it to be implicitly present. We can make this change risk-free, since if the files using these headers didn't have exposure to linux/bug.h already, they would have been causing compile failures/warnings.

timewait_sock: Create and use getpeer op.

2010-12-02T02:09:13+00:00

The only thing AF-specific about remembering the timestamp for a time-wait TCP socket is getting the peer. Abstract that behind a new timewait_sock_ops vector. Support for real IPV6 sockets is not filled in yet, but curiously this makes timewait recycling start to work for v4-mapped ipv6 sockets. Signed-off-by: David S. Miller

net: Fix memory leak in the proto_register function

2008-11-22T00:45:22+00:00

If the slub allocator is used, kmem_cache_create() may merge two or more kmem_cache's into one but the cache name pointer is not updated and kmem_cache_name() is no longer guaranteed to return the pointer passed to the former function. This patch stores the kmalloc'ed pointers in the corresponding request_sock_ops and timewait_sock_ops structures.

Replace all uses of kmem_cache_t with struct kmem_cache.
