* econet: fix lockingEric Dumazet2010-06-111-9/+18
| | | | | | | | | | | | | | econet lacks proper locking. It holds econet_lock only when inserting or deleting an entry in econet_sklist, not during lookups. - convert econet_lock from rwlock to spinlock - use econet_lock in ec_listening_socket() lookup - use appropriate sock_hold() / sock_put() to avoid corruptions.

* pkt_sched: gen_kill_estimator() rcu fixesEric Dumazet2010-06-116-3/+36
| | | | | | | | | | | | | | | | | | gen_kill_estimator() API is incomplete or not well documented, since caller should make sure an RCU grace period is respected before freeing stats_lock. This was partially addressed in commit 5d944c640b4 (gen_estimator: deadlock fix), but same problem exist for all gen_kill_estimator() users, if lock they use is not already RCU protected. A code review shows xt_RATEEST.c, act_api.c, act_police.c have this problem. Other are ok because they use qdisc lock, already RCU protected.

| | | | | | | | | | | | If oui were a null variable then vic_provinfo_alloc() would leak memory. But this function is only called from one place and oui is not null so I removed the check. I also moved the memory allocation down a line so it was easier to spot. (No one ever reads variable declarations). Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: David S.

This behavior is different then the non-accelerated path and for pkts over a bonded vlan. For example, vlanx -> bond0 -> ethx will be dropped in the vlan path and not delivered to any packet handlers at all. However, bond0 -> vlanx -> ethx and bond0 -> ethx will be delivered to handlers that match the exact dev, because the VLAN path checks the real_dev which is not a slave and netif_recv_skb() doesn't drop frames but only delivers them to exact matches. This patch adds a sk_buff flag which is used for tagging skbs that would previously been dropped and allows the skb to continue to skb_netif_recv(). Here we add logic to check for the deliver_no_wcard flag and if it is set only deliver to handlers that match exactly. This makes both paths above consistent and gives pkt handlers a way to identify skbs that come from inactive slaves. Without this patch in some configurations skbs will be delivered to handlers with exact matches and in others be dropped out right in the vlan path. I have tested the following 4 configurations in failover modes and load balancing modes. # bond0 -> ethx # vlanx -> bond0 -> ethx # bond0 -> vlanx -> ethx # bond0 -> ethx | vlanx -> -- Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S.

That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit: Timestamp incoming packets as padding bytes. PAL field is set to 8 if the PAL field is programmed to less than 8. Must be set to zero if TMR_CTRL[TE]=0. I see that the commit above sets this bit, but it doesn't handle TMR_CTRL. Manfred probably had this bit set by the firmware for his boards. But obviously this isn't true for all boards in the wild. Also, I recall that Freescale BSPs were explicitly disabling the timestamping because of a performance drop. For now, the best way to deal with this is just disable the timestamping, and later we can discuss proper device tree bindings and implement enabling this feature via some property.

The former makes it hard to debug, while the latter later causes a warning in cfg80211 when, as will typically be the case, association timed out. This warning was reported by many, e.g. in https://bugzilla.kernel.org/show_bug.cgi?id=15981, but I couldn't initially pinpoint it. I verified the fix by hacking hostapd to send a deauth frame instead of an association response.

This indicates that it actually expects RAW (read after write) type of request, so perform that when reading ELP_CTRL instead. Also cache last written value so we know what to write when doing RAW request. Because of the above it was not possible to wake the chip from ELP power saving mode, PM had to be disabled to have the driver usable in SDIO mode. After this patch PM is functional. For backporting to 2.6.34 or earlier, this patch depends on 6c1f716e8154ee9315534782b9b1eedea0559a24, which adds the required SDIO funcion.

The motivation to do this comes from a warning from lockdep which detected that we request priv->mutex while holding s_active during a sysfs request (show_statistics in the example copy pasted). The reverse order exists upon request_firmware: request_firmware which is a sysfs operation that requires s_active is run under priv->mutex. This ensures that we don't get sysfs request before we finish to request the firmware, avoiding this deadlock. ======================================================= [ INFO: possible circular locking dependency detected ] ------------------------------------------------------- cat/2595 is trying to acquire lock: (&priv->mutex){+.+.+.}, at: [<facfa598>] show_statistics+0x48/0x100 [iwlagn] but task is already holding lock: (s_active){++++.+}, at: [<c0580ebd>] sysfs_get_active_two+0x1d/0x50 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (s_active){++++.+}: [<c0489b74>] __lock_acquire+0xc44/0x1230 [<c048a1ed>] lock_acquire+0x8d/0x110 [<c0581499>] sysfs_addrm_finish+0xe9/0x180 [<c057f64a>] sysfs_hash_and_remove+0x4a/0x80 [<c05829d4>] sysfs_remove_group+0x44/0xd0 [<c0714b75>] dpm_sysfs_remove+0x15/0x20 [<c070dac8>] device_del+0x38/0x170 [<c070dc1e>] device_unregister+0x1e/0x60 [<c071838d>] _request_firmware+0x29d/0x550 [<c07186c7>] request_firmware+0x17/0x20 [<fad01bf1>] iwl_mac_start+0xb1/0x1230 [iwlagn] [<fa46ba06>] ieee80211_open+0x436/0x6f0 [mac80211] [<c0808cd2>] dev_open+0x92/0xf0 [<c0808b2b>] dev_change_flags+0x7b/0x190 [<c08148e8>] do_setlink+0x178/0x3b0 [<c0815169>] rtnl_setlink+0xf9/0x130 [<c081453b>] rtnetlink_rcv_msg+0x1bb/0x1f0 [<c0827ce6>] netlink_rcv_skb+0x86/0xa0 [<c081436c>] rtnetlink_rcv+0x1c/0x30 [<c08279c3>] netlink_unicast+0x263/0x290 [<c0828768>] netlink_sendmsg+0x1c8/0x2a0 [<c07f85fd>] sock_sendmsg+0xcd/0x100 [<c07f964d>] sys_sendmsg+0x15d/0x290 [<c07f9e6b>] sys_socketcall+0xeb/0x2a0 [<c040ad9f>] sysenter_do_call+0x12/0x38 -> #0 (&priv->mutex){+.+.+.}: [<c0489f84>] __lock_acquire+0x1054/0x1230 [<c048a1ed>] lock_acquire+0x8d/0x110 [<c08bb358>] __mutex_lock_common+0x58/0x470 [<c08bb84a>] mutex_lock_nested+0x3a/0x50 [<facfa598>] show_statistics+0x48/0x100 [iwlagn] [<c070d219>] dev_attr_show+0x29/0x50 [<c057fecd>] sysfs_read_file+0xdd/0x190 [<c052880f>] vfs_read+0x9f/0x190 [<c0528d22>] sys_read+0x42/0x70 [<c040ad9f>] sysenter_do_call+0x12/0x38 other info that might help us debug this: 3 locks held by cat/2595: #0: (&buffer->mutex){+.+.+.}, at: [<c057fe25>] sysfs_read_file+0x35/0x190 #1: (s_active){++++.+}, at: [<c0580ecd>] sysfs_get_active_two+0x2d/0x50 #2: (s_active){++++.+}, at: [<c0580ebd>] sysfs_get_active_two+0x1d/0x50 stack backtrace: Pid: 2595, comm: cat Not tainted 2.6.33-tp-rc4 #2 Call Trace: [<c08b99ab>] ? printk+0x1d/0x22 [<c0487752>] print_circular_bug+0xc2/0xd0 [<c0489f84>] __lock_acquire+0x1054/0x1230 [<c0478d81>] ? sched_clock_cpu+0x121/0x180 [<c048a1ed>] lock_acquire+0x8d/0x110 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<c08bb358>] __mutex_lock_common+0x58/0x470 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<c08bb84a>] mutex_lock_nested+0x3a/0x50 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<facfa598>] show_statistics+0x48/0x100 [iwlagn] [<c0580cf9>] ? sysfs_get_active+0x69/0xb0 [<facfa550>] ? show_statistics+0x0/0x100 [iwlagn] [<c070d219>] dev_attr_show+0x29/0x50 [<c057fecd>] sysfs_read_file+0xdd/0x190 [<c05ff314>] ? security_file_permission+0x14/0x20 [<c0528242>] ? rw_verify_area+0x62/0xd0 [<c052880f>] vfs_read+0x9f/0x190 [<c047745b>] ? up_read+0x1b/0x30 [<c057fdf0>] ? sysfs_read_file+0x0/0x190 [<c04af3b4>] ? audit_syscall_entry+0x1f4/0x220 [<c0528d22>] sys_read+0x42/0x70 [<c040ad9f>] sysenter_do_call+0x12/0x38 Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
