e100: Release skb when DMA mapping is failed in e100_xmit_prepare

2015-08-18T21:06:05Z

When pci_dma_mapping_error in e100_xmit_prepare is failed, the skb buffer allocated by netdev_alloc_skb_ip_align in e100_rx_alloc_skb is not released, which causes a possible resource leak. This patch adds error handling code to fix it. Signed-off-by: Jia-Ju Bai Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

e100: Add a check after pci_pool_create to avoid null pointer dereference

2015-08-18T21:06:05Z

The driver lacks the check of nic->cbs_pool after pci_pool_create in e100_probe. When this function is failed, a null pointer dereference occurs when pci_pool_alloc uses nic->cbs_pool in e100_alloc_cbs. This patch adds a check and related error handling code to fix it.

ethernet/intel: Use setup_timer

2015-06-01T04:46:01Z

Use the timer API function setup_timer instead of structure field assignments to initialize a timer. A simplified version of the Coccinelle semantic patch that performs this transformation is as follows: @change@ expression e1, e2, e3, e4, a, b; @@ -init_timer(&e1); +setup_timer(&e1, a, b); ... when != a = e2 when != b = e3 -e1.function = a; ... when != b = e4 -e1.data = b; Signed-off-by: Vaishali Thakkar Signed-off-by: David S.

e100: Use dma_rmb/wmb where appropriate

2015-04-09T18:25:26Z

Reduce the CPU overhead for transmit and receive by using lightweight dma_ barriers instead of full barriers where they are applicable. Cc: Jeff Kirsher Signed-off-by: Alexander Duyck Acked-by: Jeff Kirsher Signed-off-by: David S. Miller

ethernet: codespell comment spelling fixes

2015-03-09T02:54:22Z

To test a checkpatch spelling patch, I ran codespell against drivers/net/ethernet/. $ git ls-files drivers/net/ethernet/ | \ while read file ; do \ codespell -w $file; \ done I removed a false positive in e1000_hw.h Signed-off-by: Joe Perches Signed-off-by: David S. Miller

e100: fix typo in MDI/MDI-X eeprom check in e100_phy_init

2014-12-31T19:55:40Z

Although it doesn't explicitly say so, commit 60ffa478759f39a2 ("e100: Fix MDIO/MDIO-X") appears to be intended to revert the earlier commit 648951451e6d2d53 ("e100: fixed e100 MDI/MDI-X issues"). However, careful examination reveals that the attempted revert actually _inverted_ the test for eeprom_mdix_enabled. That is bound to program a few PHYs incorrectly... https://bugzilla.redhat.com/show_bug.cgi?id=1156417 Signed-off-by: "John W. Linville" Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

PCI: Remove DEFINE_PCI_DEVICE_TABLE macro use

2014-08-12T18:15:14Z

We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine Signed-off-by: Bjorn Helgaas

net: get rid of SET_ETHTOOL_OPS

2014-05-13T21:43:20Z

net: get rid of SET_ETHTOOL_OPS Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone. This does that. Mostly done via coccinelle script: @@ struct ethtool_ops *ops; struct net_device *dev; @@ - SET_ETHTOOL_OPS(dev, ops); + dev->ethtool_ops = ops; Compile tested only, but I'd seriously wonder if this broke anything.
