There is still a call to sock_prot_inuse_add() in af_netlink while in a preemptable section. Add explicit BH disable around this call. Signed-off-by:

The rule of calling sock_prot_inuse_add() is that BHs must be disabled. Some new calls were added where this was not true and this tiggers warnings as reported by Ilpo. Fix this by adding explicit BH disabling around those call sites, or moving sock_prot_inuse_add() call inside an existing BH disabled section. Signed-off-by:

Linus mentioned we could try to perform long word operations, even on potentially unaligned addresses, on x86 at least. David mentioned the HAVE_EFFICIENT_UNALIGNED_ACCESS test to handle this on all arches that have efficient unailgned accesses. I tried this idea and got nice assembly on 32 bits: 158: 33 82 38 01 00 00 xor 0x138(%edx),%eax 15e: 33 8a 34 01 00 00 xor 0x134(%edx),%ecx 164: c1 e0 10 shl $0x10,%eax 167: 09 c1 or %eax,%ecx 169: 74 0b je 176 <eth_type_trans+0x87> And very nice assembly on 64 bits of course (one xor, one shl) Nice oprofile improvement in eth_type_trans(), 0.17 % instead of 0.41 %, expected since we remove 8 instructions on a fast path. This patch implements a compare_ether_addr_64bits() function, that uses the CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS ifdef to efficiently perform the 6 bytes comparison on all capable arches.

Commit 4e4fd4e4 ("ne2k: convert to net_device_ops") exported some ei_* symbols from the 8390 library, but the axnet_cs driver defines local static versions of the same functions. Rename them to avoid the namespace conflict. Reported by Stephen Rothwell. Signed-off-by:

dev_net_set() should be the very first thing after alloc_netdev(). "ndo_" changes turned simple assignment (which is OK to do before netns assignment) into quite non-trivial operation (which is not OK, init_net was used). This leads to incomplete initialisation of tunnel device in netns.

This is the last step to be able to perform full RCU lookups in __inet_lookup() : After established/timewait tables, we add RCU lookups to listening hash table. The only trick here is that a socket of a given type (TCP ipv4, TCP ipv6, ...) can now flight between two different tables (established and listening) during a RCU grace period, so we must use different 'nulls' end-of-chain values for two tables. We define a large value : #define LISTENING_NULLS_BASE (1U << 29) So that slots in listening table are guaranteed to have different end-of-chain values than slots in established table. A reader can still detect it finished its lookup in the right chain. Signed-off-by:

The patch extends existing code: * Confirm options divide into the confirmed value plus an optional preference list for SP values. Previously only the preference list was echoed for SP values, now the confirmed value is added as per RFC 4340, 6.1; * length and sanity checks are added to avoid illegal memory (or NULL) access.

This extends the scope of two available functions, encode|decode_value_var, to work up to 6 (8) bytes, to match maximum requirements in the RFC. These functions are going to be used both by general option processing and feature negotiation code, hence declarations have been put into feat.h. Signed-off-by:

This provides function to query the current TX/RX CCID dynamically, without reliance on the minisock value, using dynamic information available in the currently loaded CCID module. This query function is then used to (a) provide the getsockopt part for getting/setting CCIDs via sockopts; (b) replace the current test for "which CCID is in use" in probe.c. Signed-off-by:

Gerrit Renker authored
With this patch, TX/RX CCIDs can now be changed on a per-connection basis, which overrides the defaults set by the global sysctl variables for TX/RX CCIDs. To make full use of this facility, the remaining patches of this patch set are needed, which track dependencies and activate negotiated feature values. Signed-off-by:
