The last hunk of this commit: commit 12d04a3c Author: Alexander Duyck <alexander.h.duyck@intel.com> Date: Wed Mar 25 22:05:03 2009 +0000 e1000e: commonize tx cleanup routine to match e1000 & igb changed the logic for determining if we should call napi_complete or not at then end of a napi poll. If the NIC is using MSI-X with no work to do in ->poll, net_rx_action can just spin indefinitely on older kernels and for 2 jiffies on newer kernels since napi_complete is never called and budget isn't decremented. Discovered and verified while testing driver backport to an older kernel. Signed-off-by:Andy Gospodarek <andy@greyhouse.net> Acked-by:

Cleanup multicast_set method to avoid an extra copy of mc_list and unwanted promiscuos sets to BE. Signed-off-by:
-
Sathya Perla authored
Currenlty multicast_set and promiscuous_config cmds -- that may be called in BH context -- use the blocking MCC mbox to post cmds. An mbox cmd is protected via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable to disable BHs while a blocking mbox cmd is in progress (and take long to finish.) This can lockup a cmd in progress in process context. So, these two cmds in BH context must use the MCC queue to post cmds. Signed-off-by:

Currenlty all cmds use the blocking MCC mbox to post cmds.

This can lockup a cmd in progress in process context. Instead cmds that may be called in BH context must use the MCC queue to post cmds. The cmd completions are rcvd in a separate completion queue and the events are placed in the tx-event queue. Signed-off-by:

If the iucv message limit for a communication path is exceeded, sendmsg() returns -EAGAIN instead of -EPIPE. The calling application can then handle this error situtation, e.g. to try again after waiting some time. For blocking sockets, sendmsg() waits up to the socket timeout before returning -EAGAIN. For the new wait condition, a macro has been introduced and the iucv_sock_wait_state() has been refactored to this macro. Signed-off-by:

This forces every update of tx ring producer to check for availability of space for next full TSO command. Earlier firmware control commands didn't care to pause tx queue. Stop the tx queue if there's not enough space to transmit one full LSO command left on the tx ring after current transmit. This avoids returning NETDEV_TX_BUSY after checking distance between producer and consumer on every cpu. Restart the tx queue only if we have cleaned up enough tx descriptors. Signed-off-by:

If the adapter is not power-manageable using either ACPI, or the native PCI PM interface, __e100_power_off() returns error code, which causes every attempt to suspend to fail, although it should return 0 in such a case. Fix this problem by ignoring the return value of pci_set_power_state() in __e100_power_off(). Signed-off-by:

This patch is inspired by patch recently posted by Johannes Berg. Basically what my patch does is to group list and a count of addresses into newly introduced structure netdev_hw_addr_list. This brings us two benefits: 1) struct net_device becames a bit nicer. 2) in the future there will be a possibility to operate with lists independently on netdevices (with exporting right functions). I wanted to introduce this patch before I'll post a multicast lists conversion. Signed-off-by:

My previous patch, which explicitly delays freeing of tnodes by adding them to the list to flush them after the update is finished, isn't strict enough. It treats exceptionally tnodes without parent, assuming they are newly created, so "invisible" for the read side yet. But the top tnode doesn't have parent as well, so we have to exclude all exceptions (at least until a better way is found). Additionally we need to move rcu assignment of this node before flushing, so the return type of the trie_rebalance() function is changed. Reported-by:

The logic in sky2_down was incorrect. Receiver could report status after rx_stop was called. The steps need to be: * stop new frames from being transmitted * shut off transmit/receive logic * synchronize with NAPI to process status info about transmitter and receiver Signed-off-by: -

Stopping all activity through ChipCmd and blindly acking the irqs is neither nice nor completely needed: the transition to low-power mode does enough work and it apparently keeps the device in a sane state. Patch suggested by a fix for http://bugzilla.kernel.org/show_bug.cgi?id=9512 The rtl_shutdown path is kept unchanged so far. Signed-off-by:

The skb mac_header field is sometimes NULL (or ~0u) as a sentinel value. The places where skb is expanded add an offset which would change this flag into an invalid pointer (or offset). Signed-off-by:

Stephen Hemminger authored
Looking at the crash in log_martians(), one suspect is that the check for mac header being set is not correct. The value of mac_header defaults to 0 on allocation, therefore skb_mac_header_was_set will always be true on platforms using NET_SKBUFF_USES_OFFSET. Signed-off-by:

commit 2b85a34e (net: No more expensive sock_hold()/sock_put() on each tx) changed initial sk_wmem_alloc value. Some protocols check sk_wmem_alloc value to determine if a timer must delay socket deallocation. We must take care of the sk_wmem_alloc value being one instead of zero when no write allocations are pending. Reported by Ingo Molnar, and full diagnostic from David Miller. This patch introduces three helpers to get read/write allocations and a followup patch will use these helpers to report correct write allocations to user. Reported-by:
