由 Eric Dumazet 提交于
Andi Kleen and Tim Chen reported huge contention on inetpeer unused_peers.lock, on memcached workload on a 40 core machine, with disabled route cache. It appears we constantly flip peers refcnt between 0 and 1 values, and we must insert/remove peers from unused_peers.list, holding a contended spinlock. Remove this list completely and perform a garbage collection on-the-fly, at lookup time, using the expired nodes we met during the tree traversal. This removes a lot of code, makes locking more standard, and obsoletes two sysctls (inet_peer_gc_mintime and inet_peer_gc_maxtime). This also removes two pointers in inet_peer structure. There is still a false sharing effect because refcnt is in first cache line of object [were the links and keys used by lookups are located], we might move it at the end of inet_peer structure to let this first cache line mostly read by cpus.

由 Ben Hutchings 提交于
For backward compatibility, we should retain the module parameters and sysfs attributes to control the number of peer notifications (gratuitous ARPs and unsolicited NAs) sent after bonding failover. Also, it is possible for failover to take place even though the new active slave does not have link up, and in that case the peer notification should be deferred until it does. Change ipv4 and ipv6 so they do not automatically send peer notifications on bonding failover. Change the bonding driver to send separate NETDEV_NOTIFY_PEERS notifications when the link is up, as many times as requested. Since it does not directly control which protocols send notifications, make num_grat_arp and num_unsol_na aliases for a single parameter. Bump the bonding version number and update its documentation.

This is now a run-time choice so that a single kernel can support both old and new generation ISI modems.

This provides support for newer ISI modems with no need for the earlier experimental compile-time alternative choice. With this, we can now use the same kernel and userspace with both types of modems. This also avoids confusing two different and incompatible state machines, actively connected vs accepted sockets, and adds connection response error handling (processing "SYN/RST" of sorts).

User-space sometimes needs this information. In particular, the GPRS context or the AT commands pipe setups may use the pipe handle as a reference. This removes the settable pipe handle with CONFIG_PHONET_PIPECTRLR. It did not handle error cases correctly. Furthermore, the kernel *could* implement a smart scheme for allocating handles (if ever needed), but userspace really cannot.

When a DNS resolver key is instantiated with an error indication, attempts to read that key will result in an oops because user_read() is expecting there to be a payload - and there isn't one [CVE-2011-1076]. Give the DNS resolver key its own read handler that returns the error cached in key->type_data.x[0] as an error rather than crashing. Also make the kenter() at the beginning of dns_resolver_instantiate() limit the amount of data it prints, since the data is not necessarily NUL-terminated. The buggy code was added in: commit 4a2d7892 Author: Wang Lei <wang840925@gmail.com> Date: Wed Aug 11 09:37:58 2010 +0100 Subject: DNS: If the DNS server returns an error, allow that to be cached [ver #2] This can trivially be reproduced by any user with the following program compiled with -lkeyutils: #include <stdlib.h> #include <keyutils.h> #include <err.h> static char payload[] = "#dnserror=6"; int main() { key_serial_t key; key = add_key("dns_resolver", "a", payload, sizeof(payload), KEY_SPEC_SESSION_KEYRING); if (key == -1) err(1, "add_key"); if (keyctl_read(key, NULL, 0) == -1) err(1, "read_key"); return 0; } What should happen is that keyctl_read() reports error 6 (ENXIO) to the user: dns-break: read_key: No such device or address but instead the kernel oopses. This cannot be reproduced with the 'keyutils add' or 'keyutils padd' commands as both of those cut the data down below the NUL termination that must be included in the data. Without this dns_resolver_instantiate() will return -EINVAL and the key will not be instantiated such that it can be read. The oops looks like: BUG: unable to handle kernel NULL pointer dereference at 0000000000000010 IP: [<ffffffff811b99f7>] user_read+0x4f/0x8f PGD 3bdf8067 PUD 385b9067 PMD 0 Oops: 0000 [#1] SMP last sysfs file: /sys/devices/pci0000:00/0000:00:19.0/irq CPU 0 Modules linked in: Pid: 2150, comm: dns-break Not tainted 2.6.38-rc7-cachefs+ #468 /DG965RY RIP: 0010:[<ffffffff811b99f7>] [<ffffffff811b99f7>] user_read+0x4f/0x8f RSP: 0018:ffff88003bf47f08 EFLAGS: 00010246 RAX: 0000000000000001 RBX: ffff88003b5ea378 RCX: ffffffff81972368 RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff88003b5ea378 RBP: ffff88003bf47f28 R08: ffff88003be56620 R09: 0000000000000000 R10: 0000000000000395 R11: 0000000000000002 R12: 0000000000000000 R13: 0000000000000000 R14: 0000000000000000 R15: ffffffffffffffa1 FS: 00007feab5751700(0000) GS:ffff88003e000000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000010 CR3: 000000003de40000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process dns-break (pid: 2150, threadinfo ffff88003bf46000, task ffff88003be56090) Stack: ffff88003b5ea378 ffff88003b5ea3a0 0000000000000000 0000000000000000 ffff88003bf47f68 ffffffff811b708e ffff88003c442bc8 0000000000000000 00000000004005a0 00007fffba368060 0000000000000000 0000000000000000 Call Trace: [<ffffffff811b708e>] keyctl_read_key+0xac/0xcf [<ffffffff811b7c07>] sys_keyctl+0x75/0xb6 [<ffffffff81001f7b>] system_call_fastpath+0x16/0x1b Code: 75 1f 48 83 7b 28 00 75 18 c6 05 58 2b fb 00 01 be bb 00 00 00 48 c7 c7 76 1c 75 81 e8 13 c2 e9 ff 4c 8b b3 e0 00 00 00 4d 85 ed <41> 0f b7 5e 10 74 2d 4d 85 e4 74 28 e8 98 79 ee ff 49 39 dd 48 RIP [<ffffffff811b99f7>] user_read+0x4f/0x8f RSP <ffff88003bf47f08> CR2: 0000000000000010 Signed-off-by: NDavid Howells <dhowells@redhat.com> Acked-by: NJeff Layton <jlayton@redhat.com> cc: Wang Lei <wang840925@gmail.com> Signed-off-by: NJames Morris <jmorris@namei.org>
